Description

Technical Field

[0001] This invention relates to the technical field of shooting equipment, and in particular to a quick-release and easy-to-use fixing device. Background Technology

[0002] In related technologies, photography equipment, such as DSLRs, is frequently favored. People typically use DSLRs for outdoor photography. When hiking, it's convenient to temporarily store the DSLR in a backpack. When encountering a scenic view or wanting to take a picture, the DSLR needs to be taken out. In some situations, the scenery is so beautiful that immediate photos are needed. However, since the DSLR is in the backpack, the backpack must be opened to retrieve it. Since some scenes are fleeting, this process of taking the backpack out takes time, causing users to miss opportunities. Therefore, it is necessary to provide a device that allows users to easily access and remove DSLRs, thus avoiding the need to repeatedly open and close the backpack. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a quick-release and easy-to-use fixing device that allows users to hang the shooting equipment on the backpack strap, thereby facilitating the user's access to and from the shooting equipment.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] Please refer to Figure 1In some embodiments, a quick-release portable mounting device 10 is used to clamp a backpack strap and connect to a shooting device. The quick-release portable mounting device 10 includes an upper shell 100, a lower shell 200, and an operating component 300. The upper shell 100 is used to connect to the shooting device. Specifically, the upper shell 100 may be provided with an Arca structure 500, so that the shooting device, such as a DSLR camera, can be connected to the upper shell 100 through the Arca structure 500. In addition to the Arca structure 500, the DSLR camera can also be connected to the upper shell 100 via a threaded connection. The DSLR camera can be connected to the upper shell 100 directly or indirectly. The lower shell 200 is rotatably connected to the upper shell 100. The operating component 300 is connected to the lower shell 200 and, together with the lower shell 200, clamps the upper shell 100. Along a first direction, the operating component 300 can move relative to the lower shell 200, pushing the upper shell 100 to move along the first direction. When the upper shell 100 moves along the first direction, it can rotate relative to the lower shell 200, so that the upper shell 100 moves closer to the lower shell 200 and together clamps the backpack strap. Specifically, please refer to... Figure 2 The upper shell 100 can be connected to a shooting device, such as a DSLR camera. By operating the operating member 300 relative to the lower shell 200, the operating member 300 pushes the upper shell 100 to move in a first direction, so that the upper shell 100 can rotate relative to the lower shell 200 when moving in the first direction. After rotating relative to the lower shell 200, the upper shell 100 can approach the lower shell 200 and together with the lower shell 200 clamp the backpack strap. A quick-release portable fixing device 10 can be clamped onto the backpack strap and can also be connected to a shooting device. Thus, the quick-release portable fixing device 10 allows the user to hang the shooting device on the backpack strap, making it convenient for the user to put on and take off the shooting device. Furthermore, the quick-release portable fixing device 10 allows the user to quickly install or remove it from the backpack strap.

[0038] Please refer to Figure 2The following describes the use of a quick-release and easy-to-use mounting device 10, in which the user attaches a DSLR camera to the upper housing 100 via a snap-fit ​​mechanism. The user then places a backpack strap between the upper housing 100 and the lower housing 200. The user then operates the operating component 300, for example, by rotating it, causing the operating component 300 to move relative to the lower housing 200 in a first direction, thus pushing the upper housing 100 to move in the first direction as well. When the upper housing 100 moves in the first direction, it can rotate relative to the lower housing 200, bringing it closer to the lower housing 200 and allowing them to jointly clamp the backpack strap. In this way, the upper housing 100 and the lower housing 200 clamp the backpack strap, thus hanging it on the backpack strap. The shooting device is indirectly hung on the backpack strap through its connection to the upper housing 100. Therefore, when the user does not need to use the DSLR, it can be hung on the backpack strap; when the user needs to use the DSLR, it can be removed. It should be noted that since the SLR camera is attached to the upper shell 100 via a snap-fit ​​mechanism, users can quickly remove or install it.

[0039] The first direction mentioned above will be explained below. When the rotating member 140 is installed on the side of the lower shell 200, the first direction can be either the length direction of the upper shell 100 or the length direction of the lower shell 200. When the operating member 300 is set as a screw, the first direction can be the axial direction of the screw. However, it should be noted that the first direction is a unidirectional direction. Only in a unidirectional direction can the operating member 300 move relative to the lower shell 200 along the first direction and push the upper shell 100 to move along the first direction.

[0040] Please refer to Figure 8 In some embodiments, the operating element 300 is threadedly connected to the lower housing 200. The operating element 300 can be a screw or a threaded rod connected to a button, allowing the user to easily rotate the button. When the user rotates the button, the threaded rod connects to the lower housing 200, shortening the distance between the button and the lower housing 200. This causes the button to push the upper housing 100 closer to the lower housing 200, and the lower housing 200 to rotate relative to the upper housing 100.

[0041] The following explanation describes how the upper shell 100 can rotate relative to the lower shell 200 when it moves along the first direction. Please refer to... Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In some embodiments, the upper shell 100 has a first connecting portion 110, which is provided with a receiving cavity 120 and a through hole 130, the through hole 130 communicating with the receiving cavity 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 receiving cavity 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, the two ends of the first guide surface 121 are connected to the first surface 122 and the second surface 123 respectively, the two ends of the first surface 122 are connected to the first guide surface 121 and the second surface 123 respectively, and the two ends of the second surface 123 are connected to the first guide surface 121 and the first surface 122 respectively. Along the first direction, the height of the first guide surface 121 gradually increases. As the height of the first guide surface 121 gradually increases, the height of the first surface 122 is higher than the height of the second surface 123 along the first direction. A part of the first surface 122 is parallel to the first direction, and another part of the first surface 122 is perpendicular to the first direction.

[0042] The lower shell 200 has a second connecting portion 250, which includes a protrusion 260 and a body portion 270. The protrusion 260 is connected to and protrudes from the outer peripheral surface of the body portion 270. The protrusion 260 includes a second guide surface 261, a third surface 262, and a fourth surface 263. Along the circumference of the body portion 270, the second guide surface 261, the third surface 262, and the fourth surface 263 are connected end to end. Specifically, the two ends of the second guide surface 261 are connected to the third surface 262 and the fourth surface 263, respectively; the two ends of the third surface 262 are connected to the second guide surface 261 and the fourth surface 263, respectively; and the two ends of the fourth surface 263 are connected to the second guide surface 261 and the third surface 262, respectively. Along the first direction, the height of the second guide surface 261 gradually increases. As the height of the second guide surface 261 gradually increases, along the first direction, the height of the third surface 262 is higher than the height of the fourth surface 263. A part of the third surface 262 will be parallel to the first direction, and another part of the third surface 262 will be perpendicular to the first direction.

[0043] Furthermore, when the first connecting part 110 and the second connecting part 250 are connected, the through hole 130 is sleeved on the outside of the main body part 270, and the receiving cavity 120 is sleeved on the outside of the protrusion 260. When the operating member 300 pushes the upper shell 100 to move relative to the lower shell 200, the first guide surface 121 and the second guide surface 261 are not yet in contact with each other, and there is a gap between the first guide surface 121 and the second guide surface 261. Therefore, as long as the upper shell 100 is pushed, under the combined action of the first guide surface 121 and the second guide surface 261, the upper shell 100 will slowly rotate relative to the lower shell 200, thereby achieving the effect of the upper shell 100 approaching the lower shell 200 and jointly clamping the backpack strap. Specifically, when the upper shell 100 approaches the lower shell 200 and can jointly clamp the backpack strap, the first guide surface 121 and the second guide surface 261 are in contact, the first surface 122 and the third surface 262 are in contact, and the second surface 123 and the fourth surface 263 are in contact. When the first guide surface 121 and the second guide surface 261 are in contact, the first surface 122 and the third surface 262 are in contact, and the second surface 123 and the fourth surface 263 are in contact, the upper shell 100 cannot rotate relative to the lower shell 200, so that the upper shell 100 and the lower shell 200 can always maintain the state of clamping the backpack strap.

[0044] Please refer to Figure 9 In some embodiments, the upper shell 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, and the other end of the rotating member 140 is rotatably connected to the first clamping member 150. The first clamping member 150 is used to clamp the backpack strap together with the lower shell 200. When the upper shell 100 and the lower shell 200 are close to each other and jointly clamp the backpack strap, the upper shell 100 is parallel to the lower shell 200. However, when the upper shell 100 is far from the lower shell 200 and is not jointly clamping the backpack strap, if the first clamping member 150 cannot rotate relative to the rotating member 140, then the first clamping member 150 and the lower shell 200 will have a certain angle and will not be parallel. In this case, the quick-release and easy-to-use fixing device 10 occupies a large space, making it inconvenient for users to store. After the first clamping member 150 and the rotating member 140 are rotatably connected, it is convenient for the user to adjust the angle of the first clamping member 150 relative to the lower shell 200 so that it can be parallel, thus facilitating storage.

[0045] Please refer to Figure 9In some embodiments, a quick-release and easy-to-use fixing device 10 further includes a fixing member 400. A first clamping member 150 is provided with a rotating hole 151. The other end of a rotating member 140 has a rotating shaft 141 disposed in the rotating hole 151. One end of the fixing member 400 is connected to the rotating shaft 141, and the other end of the fixing member 400 abuts against the first clamping member 150, and together with the rotating member 140, clamps the first clamping member 150. The length of the rotating shaft 141 is less than the depth of the rotating hole 151, and the fixing member 400 can restrict the rotation of the rotating member 140 relative to the first clamping member 150. Specifically, the fixing member 400 can be threadedly connected to the rotating shaft 141. Specifically, when installing the first clamping member 150 and the rotating member 140, the rotating shaft 141 is passed through the rotating hole 151, and then connected to the rotating shaft 141 by the fixing member 400, thereby allowing the first clamping member 150 to rotate relative to the rotating member 140. When the first clamping member 150 rotates relative to the rotating member 140, since the length of the rotating shaft 141 is less than the depth of the rotating hole 151, 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 more tightly, thus providing a damped feel to the rotation of the first clamping member 150 relative to the rotating member 140. Furthermore, it also requires a certain amount of force from the user to rotate the first clamping member 150 relative to the rotating member 140. This effectively keeps the first clamping member 150 parallel to the lower shell 200, thus ensuring a more secure grip on the backpack strap by both the lower shell 200 and the upper shell 100.

[0046] The upper shell 100 and lower shell 200 can jointly hold the backpack straps. To prevent the backpack straps from detaching from the upper shell 100 and lower shell 200 when they are held together, measures can be taken on the lower shell 200 to prevent the backpack straps from detaching. For details, please refer to... Figure 8 In some embodiments, the lower shell 200 includes a second clamping member 210 and an anti-detachment member 240. The second clamping member 210 is connected to the upper shell 100, and the anti-detachment member 240 is connected to the end of the second clamping member 210 away from the operating member 300. The anti-detachment member 240 protrudes from the second clamping member 210 toward the upper shell 100. By protruding from the second clamping member 210 toward the upper shell 100, the anti-detachment member 240 can prevent the backpack strap from detaching from the lower shell 200, thus making the quick-release and easy-to-use fixing device 10 more secure when clamped onto the backpack strap.

[0047] Furthermore, different backpacks have different strap sizes. Therefore, please refer to... Figure 10In some embodiments, the anti-slip member 240 includes an anti-slip portion 241, a connector 244, and an elastic member 245. The second clamping member 210 has a storage cavity 220, in which the connector 244 and the elastic member 245 are disposed. One end of the elastic member 245 is fixedly connected to the cavity wall of the storage cavity 220, and the other end is fixedly connected to the connector 244. The connector 244 is connected to the anti-slip portion 241, which protrudes from the second clamping member 210 towards the upper shell 100. The elasticity of the elastic member 245 allows the anti-slip portion 241 to abut against the second clamping member 210. Specifically, when encountering a backpack strap that exceeds the size of the lower shell 200, the user can pull the anti-slip portion 241, thereby indirectly extending the size of the lower shell 200 so that the backpack strap can be fully placed on the lower shell 200. Then, the upper shell 100 is brought close to the lower shell 200 to jointly clamp the backpack strap. When encountering a small backpack strap, the elastic member 245 can pull the anti-slip part 241, which can be held against the second clamping member 210. The anti-slip part 241 protrudes towards the upper shell 100 from the second clamping member 210 to prevent the backpack strap from coming off.

[0048] Furthermore, the elastic element 245 can be a spring. When the spring pulls the anti-detachment part 241 to move relative to the second clamping member 210, after pulling the anti-detachment part 241, there will be some distance between the anti-detachment part 241 and the second clamping member 210. In order to ensure that the anti-detachment part 241 returns to its original position smoothly and without deviation when the spring resets, the movement trajectory of the anti-detachment part 241 can be restricted. Please refer to... Figure 10 In some embodiments, the second clamping member 210 is further provided with a guide groove 230, which communicates with the storage cavity 220. The anti-detachment part 241 includes a supporting block 242 and a slider 243. The slider 243 is disposed in the guide groove 230 and connected to the connecting member 244. The supporting block 242 is connected to the slider 243 and protrudes from the second clamping member 210 toward the upper shell 100. Specifically, the slider 243 moves along the groove wall of the guide groove 230. The guide groove 230 can extend in a first direction, so that the cooperation between the slider 243 and the guide groove 230 enables the anti-detachment part 241 to have a set movement trajectory, so that the anti-detachment part 241 will not shake when it moves.

[0049] Specifically, after the upper shell 100 and lower shell 200 jointly clamp the backpack strap, to improve the clamping effect, the backpack strap can be prevented from moving relative to the lower shell 200 and upper shell 100. In some embodiments, the second clamping member 210 has a first anti-slip part on its end face near the upper shell 100. The first anti-slip part can be formed by uneven particles on the end face of the second clamping member 210 near the upper shell 100, thereby increasing the friction between the backpack strap and the end face. Alternatively, the first anti-slip part can be formed by applying anti-slip material or attaching anti-slip tape to the end face. Thus, by providing the first anti-slip part, the backpack strap can be prevented from sliding relative to the lower shell 200.

[0050] In some embodiments, a second anti-slip portion is provided on the end face of the upper shell 100 near the second clamping member 210. This second anti-slip portion may consist of uneven particles on the end face of the upper shell 100 near the second clamping member 210, thereby increasing the friction between the backpack strap and the end face. Alternatively, the second anti-slip portion may be formed by applying an anti-slip material or attaching anti-slip tape to the end face. Thus, by providing the second anti-slip portion, the backpack strap can be prevented from sliding relative to the upper shell 100.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
