[0030] The convenient backpack holder of the embodiment of the present application is described below with reference to the accompanying drawings. It should be noted that the first direction is shown in the left-right direction in the accompanying drawings, and the second direction is shown in the up-down direction.

[0031] Reference Figures 1 to 3 According to the embodiment of the utility model, the convenient backpack holder includes a first clamping member 100, a rotating member 300, a second clamping member 200 and a clamping member 400. The first clamping member 100 includes a first connecting portion 110 and a second connecting portion 120 connected to each other. The first connecting portion 110 and the second connecting portion 120 are respectively located on two opposite sides of the first clamping member 100 in a first direction. The rotating member 300 includes a third connecting portion 310 and a fourth connecting portion 320 connected to each other. The third connecting portion 310 extends along a second direction. The third connecting portion 310 is slidably connected to the second connecting portion 120. The second direction is perpendicular to the first direction. The second clamping member 200 includes a fifth connecting portion 210 and a sixth connecting portion 220 connected to each other. The fifth connecting portion 210 is rotatably connected to the fourth connecting portion 320. The clamping member 400 is connected to the sixth connection portion 220, and is clamped with the first connection portion 110. The clamping member 400 is used to limit the movement of the first clamping member 100 away from the second clamping member 200. A gap (not shown in the figure) is formed between the first clamping member 100 and the second clamping member 200, and the gap is used to accommodate the clamped object.

[0032] During use, the rotating member 300 connects the first clamping member 100 and the second clamping member 200, so that the first clamping member 100 can be flipped relative to the second clamping member 200. After the first clamping member 100 is flipped open, it is convenient to place a structure used for fixing, such as a shoulder strap, between the first clamping member 100 and the second clamping member 200, and the sliding of the first clamping member 100 relative to the third connecting portion 310 can conveniently adjust the gap size between the first clamping member 100 and the second clamping member 200 to adapt to shoulder straps of different sizes. After the first clamping member 100 and the second clamping member 200 clamp the shoulder strap, the first clamping member 100 and the second clamping member 200 can be relatively fixed by clamping the first connecting portion 110 with the clamping member 400, so that the position of the backpack holder can be maintained, and the operation is convenient and quick.

[0033] Specifically, the second connection part 120 is provided with a through hole, the third connection part 310 is provided as a boss, and the third connection part 310 is inserted into the second connection part 120 to achieve a sliding connection, so as to adjust the gap size between the first clamping member 100 and the second clamping member 200. The clamping member 400 can be rotatably connected to the sixth connection part 220, and the first clamping member 100 can be abutted and limited by rotating to the upper side of the first connection part 110. The clamping member 400 can be configured to be retractable along the second direction to ensure that the first clamping member 100 can be correctly limited after the gap size changes.

[0034] Among them, a fixed slide groove 140 is provided on the side of the first clamping member 100 away from the second clamping member 200, and the fixed slide groove 140 can be slidably assembled with the fixing member 700 to assemble the fixing member 700 in place. The first clamping member 100 is provided with a ejector pin 150 and an unlocking button 160, and the ejector pin 150 can abut against the fixing member 700 to limit the movement of the fixing frame from the first clamping member 100, and the unlocking button 160 can retract the ejector pin 150 to release the abutment on the fixing member 700, so as to facilitate the disassembly of the fixing member 700. The first clamping member 100 can also be provided with a ball spring to increase the sense of frustration when assembling the fixing member 700, and prompt that the fixing member 700 is assembled in place. It can be understood that the fixing member 700 is a fixed component provided with a connection structure adapted to multimedia devices such as cameras or mobile phones, and can achieve a fixed connection with the multimedia device.

[0035] Reference Figure 1 and Figure 2 In some embodiments, the rotating member 300 further includes a resisting portion 340, which is connected to the third connecting portion 310 and is used to resist the side of the first clamping member 100 away from the second clamping member 200. The resisting portion 340 resists the first clamping member 100, which can limit the probability of the first clamping member 100 being separated from the third connecting portion 310, thereby ensuring the structural stability of the backpack fastener, facilitating use and reducing the probability of component loss.

[0036] Reference Figure 1 and Figure 2 Furthermore, in some embodiments, the rotating member 300 further includes a telescopic portion 330, the telescopic portion 330 connects the third connecting portion 310 and the abutting portion 340, and the telescopic portion 330 can move relative to the third connecting portion 310 along the second direction. Through the movement of the telescopic portion 330 relative to the third connecting portion 310, the distance between the abutting portion 340 and the second clamping member 200 can be adjusted, so that after the size of the gap between the first clamping member 100 and the second clamping member 200 changes, the position of the abutting portion 340 can be changed accordingly, and after the first clamping member 100 and the second clamping member 200 are positioned with each other, the abutting portion 340 is pressed against the first clamping member 100, so as to further improve the structural stability of the backpack holder and the clamping stability of the first clamping member 100 and the second clamping member 200, and reduce the probability of the backpack holder sliding relative to the shoulder strap.

[0037] Specifically, in some embodiments, the telescopic part 330 realizes telescopic and positioning through the cooperation of the boss and the sliding groove. For example, a boss is provided on the telescopic part 330, and a sliding groove extending along the second direction is provided on the third connecting part 310, as well as a plurality of limiting grooves arranged in sequence along the second direction, each limiting groove is connected to the sliding groove, and the boss can move along the second direction in the sliding groove. When relative fixation is required, the boss is rotated into one of the limiting grooves to achieve fixation of the telescopic part 330 in the second direction.

[0038] Alternatively, in other embodiments, the telescopic part 330 is threadedly connected to the third connecting part 310. When the telescopic part 330 is rotated relative to the third connecting part 310 through the thread, the position of the telescopic part 330 relative to the third connecting part 310 can be adjusted. When the rotation stops, the pre-tightening force of the thread can be used to provide fixation to achieve telescoping and positioning.

[0039] Reference Figure 1 and Figure 2 As another improvement of the above solution, one side of the abutting portion 340 is rotatably connected to the telescopic portion 330, and the other side of the abutting portion 340 extends in a direction away from the third connecting portion 310. The abutting portion 340 extending to a certain length can facilitate the user to grasp the abutting portion 340 for telescopic extension, and the abutting portion 340 can be rotated relative to the telescopic portion 330. After the telescopic portion 330 is adjusted, the abutting portion 340 can be rotated to make the abutting portion 340 fit the first clamping member 100 as much as possible, so that the backpack holder has a compact structure and reduces space occupation.

[0040] Furthermore, a damping structure (not shown in the figure) is provided at the rotational connection between the abutting portion 340 and the third connecting portion 310, and the damping structure can provide resistance to the relative rotation between the abutting portion 340 and the third connecting portion 310, so that the abutting portion 340 can be temporarily fixed after rotating to a set position. Specifically, the damping structure can be selected as a conventional damper in the art, or an elastic damping ring can be provided at the rotational connection between the abutting portion 340 and the third connecting portion 310, so as to limit the rotation of the abutting portion 340 through the abutment of the damping ring.

[0041] Reference Figure 1 and Figure 2 In some embodiments, the first connection portion 110 is provided with a plurality of snap-fitting grooves 111, each snap-fitting groove 111 is arranged along the second direction, and the snap-fitting member 400 can enter each snap-fitting groove 111. The provision of a plurality of snap-fitting grooves 111 can adjust the snap-fitting position between the snap-fitting member 400 and the first clamping member 100. After the gap between the first clamping member 100 and the second clamping member 200 is adjusted, the snap-fitting member 400 and the sixth connection portion 220 can be snap-fitted by the snap-fitting grooves 111 at different positions. Compared with setting the snap-fitting member 400 in a retractable form, the structure is simpler, convenient to prepare and cost-saving.

[0042] Reference Figure 2 and Figure 3 In some embodiments, the clamping member 400 is slidably connected to the sixth connecting portion 220, and the clamping member 400 can move relative to the sixth connecting portion 220 along the first direction. The clamping member 400 moves away from the rotating member 300 along the first direction, and can release the abutment with the sixth connecting portion 220 to unlock the first clamping member 100, so as to facilitate the placement of the shoulder strap between the first clamping member 100 and the second clamping member 200. After the shoulder strap is in place, the clamping member 400 approaches the rotating member 300 along the first direction, and resumes the abutment with the sixth connecting portion 220 to lock the first clamping member 100. The clamping member 400 can abut against the surface of the first clamping member 100 on the side away from the second clamping member 200 in the first direction, or, in an embodiment with a clamping groove 111, the clamping member 400 is clamped in the clamping groove 111.

[0043] Furthermore, the backpack holder further comprises an elastic member 500, which is connected to the clamping member 400, and is used to drive the clamping member 400 to move in the first direction toward the side close to the rotating member 300. After the first clamping member 100 is in the unlocked state and the shoulder strap is placed on the first clamping member 100 and the second clamping member 200, the elastic member 500 drives the clamping member 400 to automatically rebound, thereby achieving the locking of the first clamping member 100, which is convenient for the use of the backpack holder. Among them, the elastic member 500 can be abutted against the side of the clamping member 400 away from the rotating member 300 on one side, and against the wall structure formed by the second clamping member 200 on the other side.

[0044] Furthermore, the backpack holder further comprises a locking member 600, which comprises a rotating portion 610 and a locking portion 620 connected to each other, wherein the rotating portion 610 is arranged at intervals on the side of the clamping member 400 away from the rotating member 300, the rotating portion 610 is rotatably connected to the sixth connecting portion 220, and the locking portion 620 can abut against the clamping member 400. When the clamping member 400 and the sixth connecting portion 220 are in a clamping state to lock the first clamping member 100, the locking portion 620 abuts against the side of the clamping member 400 away from the rotating member 300 to lock the clamping member 400, thereby preventing the clamping member 400 from moving due to other factors such as accidental touch, thereby preventing the locking of the first clamping member 100 from being misunderstood, and ensuring the stability of the backpack holder. When the first clamping member 100 needs to be unlocked, the locking member 600 is rotated until the locking portion 620 is disengaged from the clamping member 400 , and the clamping member 400 is driven to be disengaged from the abutment of the sixth connecting portion 220 , thereby unlocking the first clamping member 100 .

[0045] A ball spring may be provided on the clamping member 400 to abut against the locking member 600 to enhance the sense of frustration and remind the user that the clamping member 400 and the locking member 600 are in place.

[0046] Specifically, the clamping member 400 can be rotatably connected by the rotating shaft 240 fixed to the second clamping member 200. The rotating shaft 240 can be arranged to penetrate the clamping member 400, and the elastic member 500 can be sleeved on the rotating shaft 240, so that one end of the elastic member 500 abuts against the clamping member 400 and the other end abuts against the locking member 600, so as to provide the clamping member 400 with an elastic force for resetting.

[0047] In some embodiments, an anti-skid pad 230 can be further disposed between the first clamping member 100 and the second clamping member 200 to enhance friction and reduce the probability of the backpack fastener sliding relative to the shoulder strap.

[0048] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
