Abstract
The utility model is a locking device of leisure folding chair, including a sliding sleeve fixed on the lower of handrail and a sliding tube punctured into the sliding sleeve. Two ends of the sliding tube are respectively connected with chairback frame and legplate frame, the front end of the sliding sleeve is fixed with a holt hoop iron, the holt hoop iron is sheathed on the sliding tube, two foot-tablets of the opening of the holt hoop iron are punctured with pull rods, the lateral foot-tablet is provided with a locking piece with eccentric wheel or cam, the axle center on the position of the eccentric wheel or cam of the locking piece is provided with a pin, the pin passed through the pull hole of the pull rod is connected with the pull rod. As adopting the circular ring shaped holt hoop iron to wrap the sliding tube, when the locking piece is rotated, the eccentric wheel or cam and the holt hoop iron are compactly pressed, the pin pulls the pull rod, the holt hoop iron is hauled tight, the sliding tube is compactly hooped to lock the sliding tube. The force contact area between the holt hoop iron and the sliding tube is more than that of previous eccentric locking piece structure, the utility model is also provided with large friction, uneasy slipping and good locking effect.
Description
Technical field
The utility model relates to foldable chair, particularly to the improvement of its locking device.
Background technology
Folding seat because carry, easy to use, be widely used in stress-relieving activity.Folding seat has forms such as wooden and iron.The Wood folding chair adopts batten to make skeleton, and its chair back angular adjustment adopts the zigzag that is fixed on the handrail below to regulate stator, for many gears that progression is arranged are regulated.Iron folding seat adopts iron pipe to be bent into skeleton, its chair back angle regulator comprises the sliding sleeve that is fixed on the handrail below, and be located in slip pipe in the sliding sleeve, the two ends of slip pipe are connected on the skeleton of the chair back and leg plate, front end at sliding sleeve is inlaid with the locking plate with eccentric through-hole, slip pipe passes this eccentric through-hole, when rotating locking plate, because the endoporus off-centre of its endoporus and sliding sleeve, two hole deflections, cause the lateral pressure to slip pipe, reach the purpose of locking slip pipe, this device is the step-less adjustment of optional position.But existing apparatus is owing to the lateral pressure that has only provided a direction of slip pipe, and pressure is little, and frictional force is little, and slip pipe easily skids in sliding sleeve, and locking effect is poor.
The utility model content
The locking device of the foldable chair that the utility model purpose is to provide that a kind of frictional force is big, be difficult for skidding between slip pipe and sliding sleeve uses with convenient.
Scheme of the present utility model is: a kind of locking device of foldable chair, comprise the sliding sleeve that is fixed on the handrail below, and be located in slip pipe in the sliding sleeve, the two ends of slip pipe are connected on chair back skeleton and the leg framework, the front end of sliding sleeve is provided with anchor ear, and anchor ear is enclosed within on the slip pipe, is equipped with pull bar on two pin sheets of anchor ear opening part, the pin sheet outside is provided with the locking plate of band eccentric wheel or cam, and an end of pull bar draws and is connected on the locking plate.
The axle center at locking plate eccentric wheel or cam position is provided with pin, and the pulling eye that this pin passes pull bar is connected on the pull bar.
The utility model has the advantages that: owing to adopted circular anchor ear, be enclosed within on the slip pipe, work as rotation, the pin sheet of eccentric wheel or cam and anchor ear closely contacts, pin pulling pull bar, and the tension anchor ear, the banding slip pipe plays the effect of locking slip pipe.Stressed contact area between anchor ear and slip pipe is bigger than the stressed contact area of eccentric lock chip architecture in the past, and frictional force is big, is difficult for skidding, and locking effect is good.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is the structural representation of foldable chair.
Fig. 2 is the structural representation of this device.
Mark among the figure: 1 chair back skeleton, 2 slip pipes, 3 handrails, 4 sliding sleeves, 5 anchor ears, 6 back chair pin chutes, 7 back chair pin, 8 connecting rods, 9 locking plates, 10 front chair legs, 11 seat board skeletons, 12 leg frameworks, 13 pull bars, 14 pins.Wherein, the 51st, the pin sheet in the anchor ear; The 131st, the pulling eye in the pull bar.
The specific embodiment
Referring to Fig. 1, the locking device of the foldable chair of embodiment, comprise the sliding sleeve 4 that is fixed on handrail 3 belows, and be located in slip pipe 2 in the sliding sleeve 4, the two ends of slip pipe 2 are connected on chair back skeleton 1 and the leg framework 12 by fulcrum respectively, foldable chair is when opening and closing, slides in slip pipe 2 front and back in sliding sleeve 4.
Referring to Fig. 2, the front end of sliding sleeve 4 is provided with anchor ear 5, anchor ear 5 is enclosed within on the slip pipe 2, be equipped with pull bar 13 on two pin sheets 51 of anchor ear 5 opening parts, pin sheet 51 outsides are provided with locking plate 9, what present embodiment adopted is to be with eccentric locking plate, and an end of pull bar 13 draws and is connected on the locking plate 9, and the other end is stuck in the opposite side of pin sheet 51.
The axle center at locking plate 9 eccentric positions is provided with pin 14, and the pulling eye 131 that pin 14 passes pull bar is connected on the pull bar 13.
When as shown clockwise direction rotates 90 ° of locking plates, because closely the contacting of eccentric wheel and pin sheet 51, pull bar 13 is tightened up, and anchor ear 5 is by banding, and banding slip pipe 2 plays the effect of locking slip pipe 2, locks the angle of inclination of the chair back and leg plate at this moment.
