Abstract

A camera rack telescopic rod comprises an outer tube, a fixed tube sleeve arranged at the end part of the outer tube and an inner tube telescopically sleeved in the fixed tube sleeve, wherein a slide block, an adjusting spring and an adjusting screw are sequentially arranged in a tube wall hole of the fixed tube sleeve from inside to outside, and the inner side of the slide block is attached to the surface of the inner tube, so that the slide block is always pressed in the inner tube under the action of the adjusting spring no matter the camera rack telescopic rod is in a telescopic adjustment state or a locking state, a gap between the inner tube and the fixed tube sleeve can be eliminated, and the camera rack telescopic rod cannot shake or rock when being locked or in telescopic adjustment, so that the shooting effect is ensured; in addition, after the device is used for a period of time, the gap between the inner pipe and the fixed pipe sleeve changes due to the influence of the abrasion between the inner pipe and the sliding block and the elastic force change of the adjusting spring, and the purpose of always eliminating the gap can be achieved by screwing the adjusting screw to tighten the gap.

Description

Camera Holder Telescoping Pole

technical field

The invention relates to a photographic equipment, in particular to a telescopic pole of a camera frame.

Background technique

We know that the camera stand can adjust the shooting height of the camera and avoid shaking during shooting, so as to improve the stability of the camera and further enhance the shooting effect of the camera. The current camera stand mainly has two types of single-legged and three-legged telescopic poles. The telescopic rods are all connected together by at least two pipes from small to large, and the adjacent pipes can be adjusted up and down, and tightened by twisting the locking device after the adjustment is completed. Install the camera on the pan/tilt of the camera stand when in use, and adjust the height of the camera stand by loosening the locking device to stretch the length of the corresponding adjacent tube when necessary, and then tighten the locking device after the adjustment is completed .

At present, there are two main telescopic structures of each telescopic rod: one is that the telescopic adjustment between each section of adjacent pipes is independent, and this structure is not only time-consuming and laborious to adjust, but also relatively slow to operate; The first is that all tubes of the same telescopic rod are linked when telescopic, such as the camera frame telescopic rod of Chinese Patent No. 201230491236.1, which is convenient and fast during telescopic operation. The telescopic rods of these two structures have relatively large gaps between the tubes, and are prone to shake and shake when locked in use or telescopically adjusted, thereby affecting the shooting effect.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a camera frame telescopic rod with a more reasonable structure and the ability to eliminate the inner tube gap, which can still ensure the shooting effect during telescopic adjustment.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

A telescopic rod for a camera frame, comprising an outer tube, a fixed sleeve installed at the end of the outer tube, and an inner tube telescopically inserted into the fixed sleeve, which is sequentially inserted in the tube wall hole of the fixed sleeve from inside to outside There is a slider, an adjustment spring and an adjustment screw; the inner side of the slider is attached to the surface of the inner tube, and the adjustment screw can adjust the distance between the slider and the inner tube when the adjustment screw is turned in the hole of the tube wall. tightness.

In the improved solution to the telescopic rod of the above-mentioned camera frame, the slider is in the shape of a strip in the vertical direction; the adjustment spring acts on the middle position of the slider; There is a positioning post, and a positioning hole for the positioning post to slide therein is provided in the fixing sleeve.

Compared with the prior art, the beneficial effect of the present invention is that: since a slide block, an adjustment spring and an adjustment screw are sequentially arranged in the pipe wall hole of the fixed sleeve from the inside to the outside, the inner side of the slide block is attached to the On the surface of the inner tube, no matter whether the telescopic rod of the camera frame is in the telescopic adjustment or in the locked state, under the action of the adjustment spring, the slider is always pressed in the inner tube, so that the gap between the inner tube and the fixed sleeve can be eliminated. There is no gap between the inner tube and the slider, so that there will be no shaking or shaking when the lock is used or the telescopic adjustment is made, thus ensuring the shooting effect; Influenced by the change of the elastic force, the gap between the inner tube and the fixed sleeve will change. At this time, the purpose of eliminating the gap can be achieved by turning the adjusting screw to tighten it. Therefore, the structure of the present invention is more reasonable.

Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

【detailed description】

The present invention is a telescopic rod for a camera frame, as shown in Figures 1 to 4, comprising an outer tube 1, a fixed tube sleeve 2 mounted on the end of the outer tube 1, and an inner tube 3 telescopically inserted into the fixed tube sleeve 2 , in the pipe wall hole 21 of the fixed pipe sleeve 2, a slider 4, an adjustment spring 5 and an adjustment screw 6 are sequentially arranged from the inside to the outside, and they form a gap elimination structure, and the inner side of the slider 4 is attached to the On the surface of the inner tube 3 , the adjusting screw 6 can adjust the tightness between the slider 4 and the inner tube 3 when screwed in the tube wall hole 21 . Whether the telescopic rod of the camera frame is in the telescopic adjustment or in the locked state, under the action of the adjustment spring, the slider is always pressed into the inner tube, so that the gap between the inner tube and the fixed sleeve can be eliminated, so that the locking There will be no shaking or shaking during use or telescopic adjustment, thus ensuring the shooting effect; in addition, after a period of use, due to the wear between the inner tube and the slider and the change in the elastic force of the adjustment spring, the inner tube and the sliding block will be affected. The gap between the fixed pipe sleeves will change, and at this moment, the purpose of eliminating the gap can be achieved by turning the adjusting screw and tightening, so the structure of the present invention is more reasonable.

Preferably, the slider 4 is strip-shaped in the vertical direction to increase the contact length between the slider and the inner tube to further reduce shaking, and the adjustment spring 5 acts on the middle position of the slider 4 The upper and lower ends of the slider 4 are respectively provided with a positioning column 41, and the positioning hole 22 for the positioning column 41 to slide therein is provided in the fixed sleeve 2, so that the slider can be prevented from falling.

In summary, the above are only preferred embodiments of the present invention, and are not intended to limit the implementation scope of the present invention. That is, all equivalent changes and modifications made according to the content of the patent scope of the present invention shall belong to the technical scope of the present invention.
