Referring to fig. 1, in some embodiments, a quick-release portable fastening device 10 is used to hold a backpack strap and connect with a photographing apparatus. A quick release portable fastening device 10 comprising: an upper case 100, a lower case 200, and an operating member 300. The upper case 100 is for connection with a photographing apparatus. Specifically, the upper case 100 may be provided with an acarid structure 500 so that photographing devices such as a single lens may be connected to the upper case 100 through the acarid structure 500. Wherein, in addition to the acard structure 500, the single counter can be connected to the upper case 100 by means of screw connection. The manner of single-turn connection to the upper shell 100 may be direct connection or indirect connection. The lower case 200 is rotatably coupled to the upper case 100. The operating member 300 is connected to the lower case 200 and clamps the upper case 100 together with the lower case 200, wherein the operating member 300 is movable with respect to the lower case 200 in a first direction and pushes the upper case 100 to move in the first direction; when the upper case 100 moves in the first direction, the upper case 100 can rotate with respect to the lower case 200 so that the upper case 100 approaches the lower case 200 and can commonly clamp the backpack strap. Specifically, referring to fig. 2, the upper case 100 may be connected to a photographing apparatus, such as a single-lens connection; by operating the operation member 300 to move relative to the lower case 200, the operation member 300 is caused to push the upper case 100 to move in the first direction, so that the upper case 100 can rotate relative to the lower case 200 when the upper case 100 moves in the first direction. Wherein, after the upper case 100 rotates relative to the lower case 200, the upper case 100 can approach the lower case 200 and jointly clamp the backpack strap with the lower case 200. The quick-dismantling type portable fixing device 10 can be clamped on a backpack strap on one hand, and on the other hand, the quick-dismantling type portable fixing device 10 can be connected with shooting equipment. Thus, the quick assembly disassembly formula portable fixing device 10 can let the user hang shooting equipment on the knapsack area to the shooting equipment is got to the person of facilitating the use. And a quick release and attachment type portable fastening device 10 can be easily and quickly attached to and detached from the backpack strap by a user.
Referring to fig. 2, a method for using the quick-detachable portable fastening device 10 is described below, wherein a user can connect the single-piece fastening device to the upper case 100 by means of a fastening connection. Thereafter, the user can put the backpack strap between the upper case 100 and the lower case 200. Then, the user operates the operation member 300, such as rotating the operation member 300, so that the operation member 300 can move in the first direction with respect to the lower case 200 and push the upper case 100 to move in the first direction. When the upper case 100 moves in the first direction, the upper case 100 can rotate with respect to the lower case 200 so that the upper case 100 approaches the lower case 200 and can commonly clamp the backpack strap. In this way, the upper and lower cases 100 and 200 can clamp the backpack strap so as to be hung on the backpack strap. And the photographing apparatus is indirectly hung on the backpack strap by being connected to the upper case 100. Therefore, when a user does not need to use the single counter, the single counter can be hung on the backpack strap, and when the user needs to use the single counter, the single counter can be taken down. It should be noted that, since the upper case 100 is connected by a snap-fit manner, a user can quickly take off or install the same.
The above-mentioned first direction, which may be the length direction of the upper case 100 and the length direction of the lower case 200 when the rotation member 140 is mounted at the side of the lower case 200, will be described below. And when the operating member 300 is provided as a screw, the first direction may be the axial direction of the screw. It should be noted, however, that the first direction is a unidirectional direction, and that only in the unidirectional direction, the operating member 300 is able to move in the first direction relative to the lower housing 200 and push the upper housing 100 in the first direction.
Referring to fig. 8, in some embodiments, the operating member 300 is threadably coupled to the lower housing 200. The operation member 300 may be a screw, or the operation member 300 may be a threaded rod with threads, and the threaded rod is connected to a button, which is convenient for a user to rotate. When the user rotates the button, the screw is screw-coupled to the lower case 200, thereby shortening the distance between the button and the lower case 200, and at this time, the button pushes the upper case 100 to approach the lower case 200 and rotates the lower case 200 with respect to the upper case 100.
The description below is made of the upper case 100 being able to rotate with respect to the lower case 200 when the upper case 100 moves in the first direction. Referring to fig. 3, 4, 5, 6 and 7, in some embodiments, the upper case 100 has a first connection portion 110, the first connection portion 110 is provided with a receiving chamber 120 and a through hole 130, and the through hole 130 is communicated with the receiving chamber 120. The bottom wall of the receiving cavity 120 includes a first guide surface 121, a first surface 122 and a second surface 123. Along the circumference of the receiving cavity 120, the first guide surface 121, the first surface 122 and the second surface 123 are connected end to end. The accommodating chamber 120 may be cylindrical, wherein the first guide surface 121, the first surface 122, and the second surface 123 are connected end to end, specifically, two ends of the first guide surface 121 are connected to the first surface 122 and the second surface 123, two ends of the first surface 122 are connected to the first guide surface 121 and the second surface 123, and two ends of the second surface 123 are connected to the first guide surface 121 and the first surface 122, respectively. The height of the first guide surface 121 is gradually increased in the first direction, wherein the height of the first surface 122 is higher than the height of the second surface 123 in the first direction because the height of the first guide surface 121 is gradually increased, a portion of the first surface 122 may be parallel to the first direction, and another portion of the first surface 122 may be perpendicular to the first direction.
The lower case 200 has a second connection part 250, the second connection part 250 including a protruding part 260 and a body part 270, the protruding part 260 being connected to an outer circumferential surface of the body part 270 and protruding. The projection 260 includes a second guide surface 261, a third surface 262 and a fourth surface 263. The second guide surface 261, the third surface 262 and the fourth surface 263 are connected end to end along the circumferential direction of the body 270, wherein the second guide surface 261, the third surface 262 and the fourth surface 263 are connected end to end, specifically, both ends of the second guide surface 261 are connected to the third surface 262 and the fourth surface 263, both ends of the third surface 262 are connected to the second guide surface 261 and the fourth surface 263, and both ends of the fourth surface 263 are connected to the second guide surface 261 and the third surface 262. The height of the second guide surface 261 is gradually increased in the first direction, and thus, the height of the third surface 262 is higher than the height of the fourth surface 263 in the first direction, and a portion of the third surface 262 may be parallel to the first direction and another portion of the third surface 262 may be perpendicular to the first direction.
Further, when the first connection portion 110 and the second connection portion 250 are connected, the through hole 130 is sleeved outside the body portion 270, the accommodating cavity 120 is sleeved outside the protruding portion 260, and when the operating member 300 pushes the upper case 100 to move relative to the lower case 200, the first guiding surface 121 and the second guiding surface 261 are not attached to each other, and a gap is formed between the first guiding surface 121 and the second guiding surface 261. Therefore, when the upper case 100 is pushed, the upper case 100 is slowly rotated with respect to the lower case 200 by the combined action of the first guide surface 121 and the second guide surface 261, thereby achieving the effect that the upper case 100 approaches the lower case 200 and jointly clamps the backpack strap. When the upper case 100 is close to the lower case 200 and can clamp the backpack strap together, the first guide surface 121 and the second guide surface 261 are bonded, the first surface 122 and the third surface 262 are bonded, and the second surface 123 and the fourth surface 263 are bonded. When the first guide surface 121 is engaged with the second guide surface 261, the first surface 122 is engaged with the third surface 262, and the second surface 123 is engaged with the fourth surface 263, the upper case 100 cannot be rotated relative to the lower case 200, and the upper case 100 and the lower case 200 can always hold the backpack strap.
Referring to fig. 9, in some embodiments, the upper case 100 includes a rotating member 140 and a first clamping member 150, one end of the rotating member 140 is provided with a first connecting portion 110, the other end of the rotating member 140 is rotatably connected to the first clamping member 150, and the first clamping member 150 is used to jointly clamp the backpack strap with the lower case 200. Wherein, when the upper case 100 and the lower case 200 are close to each other and hold the backpack strap together, the upper case 100 is parallel to the lower case 200. When the upper case 100 is far from the lower case 200 and does not clamp the backpack strap together, if the first clamp member 150 cannot rotate relative to the rotating member 140, the first clamp member 150 and the lower case 200 will have a certain angle, and are not parallel. At this time, the quick assembly disassembly type portable fixing device 10 occupies a large space, and is inconvenient for a user to store. After the first clamping member 150 and the rotating member 140 are rotatably connected, the angle of the first clamping member 150 with respect to the lower case 200 can be adjusted by a user, so that the first clamping member 150 is parallel to the lower case, thereby being convenient for storage.
Referring to fig. 9, in some embodiments, a quick-detachable portable fixing device 10 further includes a fixing member 400, the first clamping member 150 is provided with a rotation hole 151, the other end of the rotation member 140 has a rotation shaft 141, the rotation shaft 141 is disposed in the rotation hole 151, one end of the fixing member 400 is connected to the rotation shaft 141, and the other end of the fixing member 400 abuts against the first clamping member 150 and clamps the first clamping member 150 together with the rotation member 140. Wherein the length of the rotation shaft 141 is smaller than the hole depth of the rotation hole 151, the fixing member 400 can restrict the rotation of the rotation member 140 with respect to the first clamping member 150. Specifically, the fixing member 400 may be screw-coupled with the rotation shaft 141, and particularly, when the first clamping member 150 and the rotation member 140 are mounted, the rotation shaft 141 is passed through the rotation hole 151 and then coupled to the rotation shaft 141 by the fixing member 400, so that the first clamping member 150 can be rotated with respect to the rotation member 140. When the first clamping member 150 rotates with respect to the rotating member 140, since the length of the rotating shaft 141 is smaller than the hole depth of the rotating hole 151. Accordingly, when the fixing member 400 is a screw, tightening the screw allows the screw and the rotating member 140 to clamp the first clamping member 150 together, thereby providing a damping effect to the rotation of the first clamping member 150 relative to the rotating member 140. In addition, when the user rotates the first clamp 150 with respect to the rotator 140, the user can rotate the first clamp 150 with a certain amount of force. This advantageously keeps the first clamping member 150 parallel to the lower shell 200 so that the lower shell 200 and the upper shell 100 together clamp the backpack strap more firmly.
Wherein the upper case 100 and the lower case 200 may jointly clamp the backpack strap. In order to prevent the backpack strap from being detached from the upper and lower cases 100 and 200 when the lower and upper cases 200 and 100 clamp the backpack strap, measures to prevent the backpack strap from being detached may be taken on the lower case 200. Specifically, referring to fig. 8, in some embodiments, the lower case 200 includes a second clamping member 210 and an anti-releasing member 240, the second clamping member 210 is connected to the upper case 100, the anti-releasing member 240 is connected to an end of the second clamping member 210 away from the operating member 300, and the anti-releasing member 240 protrudes from the second clamping member 210 toward the upper case 100. The anti-falling member 240 protrudes from the second clamping member 210 toward the upper case 100, and the anti-falling member 240 can play a role in preventing the backpack strap from falling off from the lower case 200, so that the quick assembly disassembly type portable fixing device 10 is relatively stable after being clamped on the backpack strap.
Further, the backpack strap varies in size due to the different backpacks. Thus, referring to fig. 10, in some embodiments, the anti-falling member 240 includes an anti-falling portion 241, a connecting member 244, and an elastic member 245. The second clamping member 210 is provided with a storage cavity 220, the connecting member 244 and the elastic member 245 are arranged in the storage cavity 220, one end of the elastic member 245 is fixedly connected to the cavity wall of the storage cavity 220, the other end of the elastic member 245 is fixedly connected to the connecting member 244, the connecting member 244 is connected to the anti-falling portion 241, and the anti-falling portion 241 protrudes out of the second clamping member 210 towards the upper shell 100. The elastic force of the elastic member 245 can make the anti-falling portion 241 abut against the second clamping member 210. Specifically, when the backpack strap having a size exceeding that of the lower case 200 is encountered, the user may pull the anti-falling portion 241, thereby indirectly extending the size of the lower case 200, allowing the backpack strap to be entirely put on the lower case 200, and then approach the upper case 100 to the lower case 200, thereby commonly clamping the backpack strap. When the backpack strap with smaller size is encountered, the elastic member 245 can pull the anti-falling portion 241, the anti-falling portion 241 can be always propped against the second clamping member 210, wherein the anti-falling portion 241 protrudes out of the second clamping member 210 toward the upper case 100, so that the backpack strap can be prevented from falling off.
Further, the elastic member 245 may be a spring, and when the spring pulls the anti-falling portion 241 to move relative to the second clamping member 210, after the anti-falling portion 241 is pulled, the anti-falling portion 241 has a certain distance from the second clamping member 210, so that when the spring is reset, the anti-falling portion 241 is smooth and not offset in the process of returning to the original position, and the movement track of the anti-falling portion 241 can be limited. Referring to fig. 10, in some embodiments, the second clamping member 210 is further provided with a guiding groove 230, the guiding groove 230 is communicated with the storage cavity 220, the anti-falling portion 241 includes a supporting block 242 and a sliding block 243, the sliding block 243 is disposed in the guiding groove 230 and is connected with the connecting member 244, the supporting block 242 is connected with the sliding block 243, and the supporting block 242 protrudes out of the second clamping member 210 toward the upper case 100.
