Abstract

The utility model discloses a mortised joint bracket which comprises more than three upright columns with mortises and inserted pin holes at the upper ends, cross beams and inserted pins with corresponding tenons at two ends, and a canopy frame, wherein the cross beams correspond in number to the inserted pins; and the tenons can be locked in the mortises through the inserted pins without of the risk of slipping off after the cross beams and the upright columns are completely mortised. The mortised joint bracket can be used so long as the upright columns and the cross beams are mortised and locked through the inserted pins, the canopy frame is mounted (the canopy frame is not required to be mounted if the mortised joint bracket is used indoors), and a canopy or a mosquito net is mounted. The utility model is improved on that the upper columns are retractable, each cross beams can rotate by taking the tenons at the two ends as the rotating shafts and be folded in the middle and in the suitable positions near to the two ends in double-shaft and single shaft hinge joint, and as a result, the whole bracket can be folded into a neat and compact cluster; and the mortised joint bracket is not required to be mounted or dismounted repeatedly after the first assembly, and can be opened to used or folded to be carried and put away.

Description

A kind of tenon joint type support

Technical field

The utility model relates to the support that a kind of suitable tent, mosquito net etc. use, particularly a kind of tenon joint type support.

Background technique

Existing tent bracket often adds X formula crossbeam with a kind of telescopic column and adds ceiling and be configured to, during use, by the supporting that lands of four root posts, four X formula crossbeams that link to each other with four columns with column draw back and elongated, fixing after, load onto the ceiling frame, cover tent and get final product.This support complex process, material is many, and Heavy Weight is fragile.

Summary of the invention

The purpose of this utility model: the tenon joint type support simple in structure and solid that a kind of suitable tent, mosquito net etc. use.

A kind of tenon joint type support, the corresponding two ends of column, quantity that comprise more than three upper end band mortise and hinge last have the crossbeam of the corresponding tenon of shape and latch, a ceiling frame.Wherein, latch is positioned at column inside, and it is axially axially vertical mutually with mortise, can pin the tenon of joggle in mortise.During use, crossbeam and column joggle are plugged latch, load onto ceiling frame (indoor use can not installed), set up tent or mosquito net gets final product.Support production technology of the present utility model is simple, consumptive material is few, cost is low, volume is little, in light weight, mounting or dismounting are easy, simple in structure firmly.

Further, formed angle is connected and fixed by diagonal control arm between column and crossbeam and crossbeam and the crossbeam.

Further again, described column and crossbeam can stretch.

Further, described column can stretch, and described crossbeam can carry out the two-part doubling from the centre, and its two ends can be carried out oppositely downward 90 degree flexions respectively by the tenon place, and entire bracket can realize foldable integral; Again, but the tenon joint type support of this foldable integral, the mortise of its column upper end and the tenon at crossbeam two ends are circular, on the tenon arc surface on column the corresponding position of hinge last have and the corresponding circular groove of latch, tenon can be pinned by latch behind the joggle fully, can not deviate from vertically, but can in mortise, rotate along circular groove; Again, there is telescopic projection on column mortise next door, then there is corresponding depression on crossbeam tenon next door, it is concavo-convex when overlapping behind the joggle with the tenon to be that axle rotates to, telescopic projection enters recess, rotation is blocked temporarily reaches the rotation positioning purpose, scalable projection withdrawal when strengthening rotating force, and rotation can continue.

Like this, the crossbeam that joggle is good is rotary, and support is opened and crossbeam is gone to not downwards the position of flexion and just can use under situation about not dismantling, and the position that goes to flexion downwards is just collapsible, and folding back is easy to carry and store.

Embodiment

Below the utility model will be further described by embodiment.

Embodiment one

With reference to Fig. 1, Fig. 2, Fig. 2 a: a kind of improved mode of the present utility model---a kind of tenon joint type support, comprise: 1 four on the column of upper end band mortise 2.2 and hinge last 3.1,2 four on the crossbeam of two ends band tenon 2.1,3 four of latches, 4 one on ceiling frame, 5 eight of diagonal control arms, 6 four of vertical rod foots pad.Wherein, the tenon 2.1 at described crossbeam 2 two ends is all made small one and large one double tenon, and its big tenon tenon body has groove to be locked in the mortise by latch, and little tenon plays auxiliary fixation; The mortise 2.2 of described column 1 upper end also be corresponding small one and large one, the mortise on its two adjacent surfaces is interlaced 2.2 about, can same latch 3 pins and inserts its interior tenons 2.1 (shown in enlarged view 2a).Like this, with above-mentioned crossbeam 2 and column 1 joggle, plug latch 3, connect diagonal control arm 5, load onto ceiling frame 4, tent or mosquito net on the cover just can use, and it is installed and removed and makes things convenient for, and remove also to be easy to carry or to preserve, not the side of occupation of land.

Implement mode of execution two

With reference to Fig. 3, Fig. 3 a, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9: the improved mode of another kind of the present utility model---a kind of tenon joint type folding rack, comprise: the upper end with circular mortise 2.4 and hinge last 3.1, ceiling frame fixed hole 4.1 and scalable protruding 2.5, there is 1 four on the column of foot pad 6 lower end, have on the end face of two ends cylindrical tenon 2.3, near end face area have can 90 hinged 2.2, the centre of the single shaft sheet of degree flexions 2 four on the crossbeam of can 180 degree folding twin shaft sheet hinged 2.1 is arranged, 3 four of latches, 4 one on ceiling frame, 5 eight of diagonal control arms.Wherein, the next door of tenon 2.3 has with scalable protruding 2.5 caves in accordingly, have on the arc surface of tenon 2.3 and hinge last 3.1 and latch 3 corresponding circular grooves (as shown in Figure 5), the latch 3 that joggle well can be inserted into later hinge last 3.1 pins from circular groove, tenon 2.3 can rotate in mortise 2.4 but can not deviate from vertically, crossbeam 2 rotates to sags and crests when overlapping, telescopic protruding 2.5 enter recess, rotation is blocked temporarily reaches the rotation positioning purpose, scalable projection withdrawal when strengthening rotating force, rotation can continue.Like this, with above-mentioned four collapsible crossbeams 2 and four scalable column 1 joggles, plug latch 3, column 1 is stretched to ideal height, adjusts crossbeam 2 and connect diagonal control arm 5, load onto ceiling frame 4, bracket with foldable has just installed, and tent or mosquito net can use on the cover.Opening and using with the folding operation of carrying, depositing afterwards is then very simple: with reference to accompanying drawing, wherein, Fig. 3 is a user mode, Fig. 3 a is complete folded state, Fig. 4 is five kinds of representative states that are folded to the process that opens and uses fully fully, its operating process: from opening and using A condition, the first step fully: pull down ceiling frame 4, turn on the crossbeam 2 fixedly the screw of diagonal control arm 5 and diagonal control arm 5 is allocated to parallel with column 1, crossbeam 2 revolved turn 90 degrees, become the B state to flexion downwards; Second step: four crossbeams 2 from dual-shaft articulation 2.1 downward flexions, are become the C state; The 3rd step: scalable column 1 is contracted to the shortest, become the D state; The 4th step: four root posts 1 are closed up to cluster to the entire bracket center, become the E state.Otherwise, then can open and use.
