[0045] The following is a reference to the appendix. Figures 1 to 7 The specific embodiments of this application will be described in further detail below.

[0046] This utility model provides a quick-release connection device 100, which can install electronic products, connect them to an object to be secured, and quickly separate the electronic products from the object when needed. In this embodiment, the electronic products include digital products such as mobile phones and cameras, while the objects to be secured include the straps of backpacks and school bags. It is understood that the electronic products can also be monitors, and the objects to be secured can be stands on campsites, in rooms or RVs, on walls, or on brackets.

[0047] This embodiment uses the quick-release connector 100 to connect digital products to the shoulder straps of a backpack as an example for detailed explanation. The connector 20 is equivalent to a backpack clip, which can be installed on the shoulder straps of the backpack and detachably connect digital products such as cameras and mobile phones.

[0048] Reference Figure 1 and Figure 2The quick-release connector 100 includes a connector 20, a locking component 53, and a mounting component 60. The connector 20 is fixed to the backpack strap, the locking component 53 is movably installed inside the connector 20, and the mounting component 60 is detachably installed in the connector 20 and engages with the locking component 53 to secure digital products such as cameras and mobile phones.

[0049] The connector 20 includes a connecting part 50, a locking part 95, and a base 93. The connecting part 50 and the base 93 are separable and form a gap to clamp the backpack straps. The locking part 95 securely connects the connecting part 50 and the base 93, so that the backpack straps are stably clamped between the connecting part 50 and the base 93.

[0050] Specifically, the connecting portion 50 is arc-shaped at one end near the mounting member 60, and an opening 501 is formed at the center of the arc. The connecting portion 50 is hollow inside and houses the fixing portion 51. The fixing portion 51 includes a base plate, a first mounting portion 511 protruding from the base plate, and two second mounting portions 513 protruding from both sides of the first mounting portion 511. The size of the base plate is the same as the bottom surface of the connecting portion, thereby sealing the bottom surface of the connecting portion 50 and making the connecting portion closed. The first mounting portion 511 is cylindrical, and a recessed portion 510 is formed inside. The recessed portion 510 and the opening 501 are opposite to each other and communicate with each other. The recessed portion 510 and the opening 501 together form an insertion recess, allowing the mounting member 60 to enter through the opening 501 and slide into the recessed portion 510 until the mounting member 60 abuts against the bottom surface of the recessed portion 510, i.e., the bottom surface of the insertion recess.

[0051] The second mounting portion 513 has a receiving space inside, and a mounting hole is provided through the second mounting portion 513. The mounting hole and the inner sidewall of the recess 510 are interconnected. The mounting hole is used to receive the engaging member 53. In this embodiment, the opening direction of the mounting hole is perpendicular to the recess direction of the recess 510. The mounting member 60 can pass through the recess 510 and is located between the two engaging members 53. When the mounting member 60 is inserted into the connecting portion 50 through the opening 501 and its end abuts against the bottom surface of the recess 510, the two engaging members 53 are elastically squeezed and elastically restored to engage with the sidewall of the mounting member 60, thereby realizing the quick connection between the mounting member 60 and the connecting portion 50.

[0052] Reference Figure 4 and Figure 5Each engaging component 53 includes a engaging arm 531 and a first elastic portion 533. The first elastic portion 533 is elastic and is housed within the receiving space of the second mounting portion 513, such that it is clamped between the engaging arm 531 and the inner wall of the connector 20. One end of the first elastic portion 533 is fixedly sleeved on the outer periphery of one end of the engaging arm 531, and the other end is fixed to the inner sidewall of the connector 50. A portion of the engaging arm 531 is housed within the receiving space of the second mounting portion 513, and another portion protrudes into the recess 510 through a mounting hole. Specifically, the end of the engaging arm 531 furthest from the first elastic portion 533 protrudes from the mounting hole and is located within the recess 510, allowing it to slide relative to the mounting member 60. When the mounting member 60 abuts against the bottom surface of the recess 510, the engaging arm 531, with the elastic release of the first elastic portion 533, slides and engages with the sidewall of the mounting member 60.

[0053] The base 93 is installed on the side of the base plate away from the first mounting part 511. The base 93 and the connecting part 50 are locked together by the locking part 95. In this embodiment, two locking parts 95 are provided. Each locking part 95 passes through one end of the connecting part 50 and the base 93 and is fixed to the connecting part 50 and the base 93 by a threaded connection. When the locking part 95 is loosened, there is a gap between the connecting part 50 and the base 93, and a backpack strap can be inserted. Tightening the locking part 95 will fix the quick-release connecting device 100 to the backpack strap.

[0054] Furthermore, an anti-slip part 91 is installed between the base plate and the base 93 to further position the quick-release connecting device 100 and prevent it from slipping off the backpack strap.

[0055] Mounting member 60 includes housing 10 and connecting part 70. An insertion hole is provided on the back of housing 10. One end of connecting part 70 is fixed to the inner side wall of insertion hole, and the other end passes through insertion hole and partially passes through opening 501 into recess 510 until it abuts against the bottom surface of recess 510, and at the same time, the engaging member 53 abuts against the two side walls of connecting part 70.

[0056] Specifically, the housing 10 has a mid-frame structure, with through openings 11 at both ends inside. Electronic devices such as cameras and mobile phones are inserted and fixed in the openings 11 for stable shooting. Support members 13 protrude from both sides of the housing 10. Each support member 13 includes two side-by-side spaced support parts, forming a placement space between adjacent support parts for placing auxiliary shooting items such as microphones and fill lights.

[0057] The joint 70 includes a main body 71, a contact portion 73 mounted on the main body 71, and a cover 72. The cover 72 covers one end of the main body 71, and the contact portion 73 protrudes from the end of the main body away from the cover 72 and can pass through the opening 501 and the recess 510 until it is elastically compressed against the bottom surface of the recess 510.

[0058] The main body 71 has a hollow cylindrical structure inside, with an opening at one end and a receiving recess inside. A receiving hole is formed through the bottom of the receiving recess. The cover 72 covers the opening and has an opening, a receiving recess, and a receiving hole formed sequentially, and the opening, receiving recess, and receiving hole are interconnected with the outside. In this embodiment, the diameters of the opening, receiving recess, and receiving hole decrease sequentially. A recess 75 and a guide groove 77 are installed on the side wall of the main body 71. Two engaging members 53 enter from the guide groove 77 and move towards the recess 75 under the drive of an external force. When the contact part 73 abuts against the bottom surface of the recess 510 and is compressed, the two engaging members 53 move to the side wall of the recess 75 near the guide groove 77 and are elastically released by the first elastic part 533 to abut against the end face of the recess 75, thereby realizing the connection between the connecting part 70 and the connecting part 50. When the engaging member 53 needs to disengage from the recess 75, the connecting part 70 is pressed and rotated, causing the contact part 73 to be further compressed. The main body 71 moves toward the recess 510, while the engaging member 53 moves away from the guide groove 77 and slides in the recess 75 and gradually disengages from the main body 71, thereby achieving the separation of the connecting part 70 and the connecting part 50.

[0059] Reference Figure 6 Specifically, the guide groove 77 is formed by gradually recessing from the side wall end face of the main body 71 near the contact portion 73 along the length of the main body 71, and the depth of its recess towards the main body 71 gradually decreases from the side wall end face towards the middle of the side wall of the main body 71, so that the distance between the connecting portion 50 and the locking arm 531 gradually decreases. When the connecting portion 70 is viewed from the end face of the connecting portion 50, the end face of the guide groove 77 forms an inclined guide surface 771, which is trapezoidal in shape, and the cross-sectional area gradually decreases from the side wall end face along the middle of the side wall. When the locking arm 531 gradually slides from one end of the guide surface 771 near the contact portion 73 towards the end away from the contact portion 73, the distance between the locking arm 531 and the inner side wall of the connecting portion 50 is shortened, and the first elastic portion 533 is elastically compressed.

[0060] The recess 75 is located on one side of the guide groove 77 and approximately in the middle of the side wall of the main body 71. The recess 75 includes a slot 751 and an inclined groove 753 arranged side by side. A clamping part 78 and a mounting block 79 are installed between the slot 751 and the inclined groove 753, and the slot 751 and the inclined groove 753 are isolated from each other by the clamping part 78 and the mounting block 79. The locking part 78 is located on the side of the slot 751 near the guide groove 77, and it can abut against the outer wall of the engaging member 53. The mounting block 79 is mounted side by side on one side of the locking part 78. Its cross-sectional area along the length direction perpendicular to the main body 71 is slightly larger than the depth of the slot 751 and the inclined groove 753, so that the locking arm 531 can be locked in the slot 751 and is limited by the slot 751 and the locking part 78 and cannot slide. When the mounting member 60 presses towards the connector 20, that is, when the engaging part 70 moves relative to the locking arm 531, the locking arm 531 can move along the slot 751, pass over the mounting block 79, slide into the inclined groove 753, and slide out of the main body 71 from the inclined groove 753.

[0061] The slot 751 is recessed from the side wall of the main body 71 inward, and its recess depth is greater than that of the guide groove 77, thus forming a stepped structure between the guide groove 77 and the slot 751, preventing the locking arm 531 from moving back into the guide groove 77. One side of the slot 751 is connected to the locking part 78 and the mounting block 79, and the other end has an arc-shaped structure. The arc shape of the end face of the slot 751 near the guide groove 77 is the same as the shape of the locking arm 531. Thus, when the locking arm 531 slides from the guide groove 77 into the slot 751, it can be stably locked in the slot 751. The arc-shaped structure of the slot 751 near the mounting block 79 is defined as a guide surface 751a, which can guide the locking arm 531 along the direction of the guide surface 751a, across the mounting block 79, and into the inclined groove 753, from which it disengages from the main body 71.

[0062] Reference Figure 7Two locking points, A and B, are formed on the slot 751. Locking point A is located between the inner wall of the slot 751 and the clamping part 78, serving as the mounting point for fixing the locking arm 531 within the main body 71. Locking point B is located between the guide surface 751a and the mounting block 79, serving as the final sliding point for the locking arm 531 within the slot 751 as it slides along the guide surface 751a. When the locking arm 531 slides along the guide surface 771 and into the slot 751, the distance between the locking arm 531 and the inner wall of the connecting part 50 increases, releasing the first elastic part 533. This causes the locking arm 531 to abut against locking point A, and both ends to be clamped between the side wall of the slot 751 and the clamping part 78. At this time, the contact part 73 is compressed and elastically abuts against the bottom surface of the recessed part 510. When the main body 71 is pressed, causing the contact part 73 to be elastically squeezed again in the direction of the bottom surface of the compression recess 510, the locking arm 531 slides along the guide surface 751a and moves to the B locking point. When the joint part 70 is rotated in the direction of the locking part 78, the locking arm 531 crosses the mounting block 79 from the B locking point and slides to the inclined groove 753.

[0063] In this embodiment, both the locking arm 531 and the locking groove 751 are made of rigid material. When the first elastic part 533 is released and the locking arm 531 abuts against the locking groove 751, the locking arm 531 will instantly produce a striking sound because the locking groove 751 and the guide groove 77 are stepped structures, to remind the connecting part 70 and the connecting part 50 to complete the connection.

[0064] The inclined groove 753 is located on one side of the slot 751 and is separated from the slot 751 by the clamping part 78 and the mounting block 79. The inclined groove 753 is formed by a gradual indentation from the middle of the side wall of the main body 71 toward the end of the side wall, and the depth of the indentation gradually decreases. The side wall of the inclined groove 753 away from the mounting block 79 forms a guide surface 753a. The outer side wall of the clamping arm 531 is in contact with the guide surface 753a, the clamping part 78, and the mounting block 79. Under the guidance of the guide surface 753a and the elastic compression of the first elastic part 533, the clamping arm 531 slides and gradually moves away from the inclined groove 753, and finally separates from the main body 71, realizing the separation of the joint part 70 and the connecting part 50.

[0065] Reference Figure 4 and Figure 5 The contact portion 73 is installed at the end of the main body portion 71 near the connecting portion 50. The contact portion 73 includes a spring arm 731 and a second elastic portion 733 that is elastic.

[0066] One end of the spring arm 731 is received within the receiving recess of the main body 71, and the other end protrudes from the outside of the main body 71 through the receiving hole. The second elastic part 733 is received within the receiving recess of the main body 71, with one end sleeved on one end of the spring arm 731 and the other end contacting the cover 72, such that the second elastic part 733 is located between the cover 72 and the spring arm 731. One end of the spring arm 731 protrudes from the main body 71, and when the engaging member 53 slides in the guide groove 77, the spring arm 731 gradually approaches the fixing part 51, while the second elastic part 733 is elastically compressed until the spring arm 731 abuts against the bottom surface of the recess 510. When the locking arm 531 is fixed at locking point A, the second elastic part 733 is still in a compressed state and generates a resistance force to recover elastic deformation in the direction of the connecting part 50, so that the elastic arm 731 is stably abutted against the bottom surface of the recessed part 510 and is stably locked at locking point A. When the second elastic part 733 is squeezed again, the locking arm 531 can slide from locking point A along the guide surface 751a to locking point B. When the fixing part 51 is rotated, so that the locking arm 531 passes over the mounting block 79 and disengages from the inclined groove 753 from the main body part 71, the elastic arm 731 and the fixing part 51 gradually separate, the second elastic part 733 recovers elastic deformation, and the elastic arm 731 resets in the direction away from the main body part 71.

[0067] When installing the quick-release connector 100, firstly, insert the connecting part 70 into the insertion hole of the housing 10 and fix one end to the inner side wall of the insertion hole. Then, align the other end of the connecting part 70 with the opening 501 of the connecting part 50, pass through the opening 501, and insert it into the recess 510. The two locking arms 531 slide into the locking groove 751 along the direction of the guide groove 77. At the same time, the contact part 73 is squeezed and abuts against the bottom surface of the recess 510. The locking arms 531 are fixed in the locking point A in the locking groove 751. At this time, the connecting part 70 and the connecting part 50 are connected. Then, the anti-slip part 91 and the base 93 are installed on the end of the connecting part 50 away from the connecting part 70, and the connecting part 50 and the base 93 are fixed by the locking part 95.

[0068] When using the quick-release connector 100, first, loosen the locking part 95, place the backpack strap between the anti-slip part 91 and the base 93, and then tighten the locking part 95 to fix the backpack strap between the connecting part 50 and the base 93. Next, pass the connecting part 70 through the insertion hole of the housing and fix one end to the side wall of the insertion hole. Then, insert one end of the connecting part 70 into the recessed part 510 through the opening 501. When you hear the click sound of the locking arm 531 engaging with the locking groove 751, the quick-release connector 100 is installed. Then, fix electronic devices such as mobile phones and cameras into the opening 11 of the housing 10, and fix items such as fill lights into the placement space between the support members 13. After the quick-release connector 100 is used, first, press and rotate the connecting part 70, the second elastic part 733 is compressed, the spring arm 731 is driven to move towards the inside of the main body part 71, the locking arm 531 slides along the guide surface 751a in the locking groove 751 and passes over the mounting block 79 to disengage from the inclined groove 753. Next, loosen the locking part 95 to separate the base 93 and the connecting part 50 from each other, take out the backpack strap, and finally take out the digital product from the housing 10. The quick-release connector 100 is now separated from the backpack strap.

[0069] In this invention, the quick-release connector 100 has its connector 20 fixedly mounted on the backpack strap. The engaging component 53 is elastically deformed and mounted on the connector 20. Digital products such as mobile phones and cameras are mounted on the mounting component 60. Pressing the mounting component 60 downwards towards the connector 20 causes it to engage with the engaging component 53, thus allowing for quick and easy mounting of digital products onto the backpack without disassembling the connector 20. This makes installation convenient and easy to use. Furthermore, when holding the digital product, simply rotating the mounting component 60 relative to the connector 20 and pulling it out allows for quick removal of the digital product without disassembling the connector 20, making the overall operation convenient.
