Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present application, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0032] The quick release assembly is widely used in many fields and products due to its convenience and practicality. For example, it is used in the quick release buckle on the shoulder strap and waist belt of a backpack, and in the camera quick release for photography enthusiasts to carry and fix their cameras. The quick release assembly 100 can usually separate the main structure from the quick release part 107 by simple operation. For example, in daily use, the existing camera quick release often causes the button on one side to be accidentally touched, resulting in the quick release part 107 being separated from the main structure, which easily causes the object to fall off and be damaged.

[0033] In order to solve the above technical problems, the embodiment of the present application provides a quick-hanging assembly 100 and a camera strap.

[0034] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the embodiment of the present application provides a quick-hanging assembly 100, including a main body mounting block 101 and a first button 102 and a second button 103 respectively arranged on opposite sides of the main body mounting block 101; a locking structure 104 and a linkage lock 105 located between the first button 102 and the second button 103 are arranged in the main body mounting block 101; one side of the locking structure 104 is connected to the first button 102, and the other side close to the second button 103 has an effective contact surface 106 that abuts against the linkage lock 105; the main body mounting block 101 is provided with a locking structure 104 and a linkage lock 105 between the first button 102 and the second button 103; A quick-install part 107 is inserted on the mounting block 101, and the locking structure 104 abuts against the quick-install part 107 to generate a force that prevents the quick-install part 107 from escaping from the main mounting block 101, thereby achieving locking; when the first button 102 and the second button 103 are pushed closer to each other, the second button 103 pushes the interlocking lock part 105 and separates the interlocking lock part 105 from the effective contact surface 106; and the first button 102 pushes the locking structure 104 to move and separate from the quick-install part 107, so that the quick-install part 107 can be pulled out of the main mounting block 101.

[0035] The quick-hanging assembly 100 provided in the embodiment of the present application is provided with a first button 102 and a second button 103 on opposite sides of the main body mounting block 101, and the quick-installing member 107 is inserted on the main body mounting block 101 between the first button 102 and the second button 103. It should be noted that the locking structure 104 provided in the embodiment of the present application can be engaged with the quick-installing member 107 to generate a force to prevent the quick-installing member 107 from escaping from the main body mounting block 101.

[0036] It should be noted that the embodiment of the present application uses a linkage lock 105 connected to the second button 103 to abut against the locking structure 104 to lock the first button 102 to prevent accidental contact with the first button 102, causing the quick-install part 107 to fall out of the main mounting block 101.

[0037] Among them, if the first button 102 is pressed unilaterally, the linkage lock 105 abuts against the locking structure 104, and the first button 102 cannot be pressed. Therefore, neither the first button 102 nor the locking structure 104 moves, enabling the locking structure 104 to maintain a stable clamping relationship with the quick-mounting part 107.

[0038] Among them, if the second button 103 is pressed unilaterally, the second button 103 pushes the linkage lock 105 to move, causing the linkage lock 105 to separate from the effective contact surface 106, and only unlocking the locking structure 104.

[0039] Therefore, in the embodiment of the present application, whether the first button 102 is accidentally touched unilaterally or the second button 103 is accidentally touched, the quick-hanging component 100 cannot be unlocked, realizing the reliable connection of the quick-hanging component 100.

[0040] The embodiment of the present application provides a quick-hanging component 100, including a main body mounting block 101 and a first button 102 and a second button 103 respectively arranged on opposite sides of the main body mounting block 101; a locking structure 104 and a linkage lock 105 are arranged between the first button 102 and the second button 103 in the main body mounting block 101 of the embodiment of the present application; wherein, one side of the locking structure 104 is connected to the first button 102, and the other side close to the second button 103 has an effective contact surface 106 that abuts against the linkage lock 105. In the embodiment of the present application, the linkage lock 105 abuts against the locking structure 104 to generate a force that blocks the movement of the first button 102 towards the second button 103, realizing double locking and preventing the situation that the quick-hanging component 100 is unlocked due to accidental unilateral touching of the first button 102.

[0041] A quick-mounting part 107 is inserted into the main body mounting block 101 of the embodiment of the present application, and the locking structure 104 abuts against the quick-mounting part 107 to generate a force that blocks the quick-mounting part 107 from disengaging from the main body mounting block 101; in the embodiment of the present application, the locking structure 104 abuts against the quick-mounting part 107 to realize the limit locking of the quick-mounting part 107, realizing the reliable insertion and locking of the quick-mounting part 107 on the main body mounting block 101.

[0042] In the embodiment of the present application, the first button 102 and the second button 103 are simultaneously subjected to a thrust force. When the first button 102 and the second button 103 approach each other, the second button 103 pushes the linkage lock 105 and causes the linkage lock 105 to separate from the effective contact surface 106, releasing the double lock; at the same time, the first button 102 pushes the locking structure 104 to move and separate from the quick-mounting part 107, so that the quick-mounting part 107 can be pulled out from the main body mounting block 101.

[0043] Compared with the prior art, in the embodiment of the present application, it is necessary to press both sides simultaneously to unlock the product, effectively preventing the unlocking situation caused by accidental touch on one side, making the quick-release component 100 safer and more reliable.

[0044] Wherein, the first button 102 is in abutting connection and linkage with the locking structure 104, or the first button 102 and the locking structure 104 are integrally formed.

[0045] Wherein, the first button 102 and the second button 103 approach each other under the thrust force, and the linkage lock 105 is separated from the effective contact surface 106, so that the locking structure 104 can move to unlock the quick-installation part 107.

[0046] As an optional implementation manner, the first button 102 is connected to the main body mounting block 101 through a first sliding component, and / or the second button 103 is connected to the main body mounting block 101 through a second sliding component whose sliding direction is parallel to the sliding direction of the first sliding component.

[0047] Refer to Figure 2 、 Figure 3 As shown in the figure, wherein, the first sliding component includes a first sliding groove 111 provided on the main body mounting block 101, and the first button 102 is embedded in the first sliding groove 111; the second sliding component includes a second sliding groove 117 provided on the main body mounting block 101, and the second button 103 is embedded in the second sliding groove 117.

[0048] It should be noted that the first sliding groove 111 and the second sliding groove 117 are parallel to each other. According to needs, the first sliding groove 111 and the second sliding groove 117 can be arranged in parallel at intervals, that is, the first button 102 and the second button 103 are arranged at intervals in the direction perpendicular to the extending path of the first sliding groove 111.

[0049] Refer to Figure 2 、 Figure 3 As shown in the figure, preferably, the first sliding groove 111 and the second sliding groove 117 are on the same straight line. In the embodiment of the present application, the first sliding groove 111 and the second sliding groove 117 are arranged on the same straight line, so that the first button 102 and the second button 103 are exactly corresponding, and it is convenient for the user to press the first button 102 and the second button 103 simultaneously to achieve quick operation with one hand.

[0050] Refer to Figure 2 As shown in the figure, as an optional implementation manner, a first elastic member 112 is provided in the main body mounting block 101, and the first elastic member 112 is compressed to form an elastic force that pushes the first button 102 to move away from the second button 103; a second elastic member 113 is provided in the main body mounting block 101, and the second elastic member 113 is compressed to form an elastic force that pushes the second button 103 to move away from the first button 102.

[0051] It should be noted that in the embodiment of the present application, the first elastic member 112 and the second elastic member 113 can enable the first button 102 and the second button 103 to generate elastic forces against pressure respectively. When the first button 102 and the second button 103 move in the first sliding groove 111 and the second sliding groove 117 respectively under pressure, the first elastic member 112 and the second elastic member 113 store elastic potential energy, forming elastic forces acting on the first button 102 and the second button 103, so that the first button 102 and the second button 103 have a reset movement tendency.

[0052] It should be noted that during reset, the first button 102 and the second button 103 can be flush with the surface of the main body mounting block 101. Those skilled in the art can set it according to needs and no special limitation is made here.

[0053] In addition, according to needs, the first button 102 and the second button 103 can also be slightly protruded from the surface of the main body mounting block 101, which is convenient for the user's finger to quickly touch the button and facilitates pressing.

[0054] During specific operation, two fingers can be used to generate a pressing force to push the first button 102 and the second button 103 closer to each other.

[0055] Refer to Figure 2 As shown, further, the first button 102 abuts against the locking structure 104, and the locking structure 104 is slidably arranged in the main body mounting block 101; a third elastic member 114 is arranged in the main body mounting block 101, and the third elastic member 114 is compressed to form an elastic force that pushes the locking structure 104 to move in the direction close to the first button 102.

[0056] That is to say, the first button 102 and the locking structure 104 are two structural members; it should be noted that according to needs, the first button 102 and the locking structure 104 can also be integrally formed, which is beneficial to reducing the structure and improving the stability and reliability of the whole structure.

[0057] Refer to Figure 2 、 Figure 3 And Figure 4 As shown, as an optional implementation manner, the second button 103 has a convex portion 108 extending toward the first button 102; the linkage lock 105 is provided with a rotating shaft 109 perpendicular to the sliding direction, and the linkage lock 105 is provided with a first extension arm 115 and a second extension arm 116 extending radially along the rotating shaft 109; the first extension arm 115 abuts against the effective contact surface 106, and the second extension arm 116 abuts against the convex portion 108; the second button 103 drives the convex portion 108 to move toward the first button 102, pushes the second extension arm 116 and drives the first extension arm 115 to rotate around the rotating shaft 109 in the direction away from the effective contact surface 106.

[0058] It should be noted that the second button 103 can push the linkage lock 105 to rotate around the rotation shaft 109 through the protrusion 108. A torsion spring can be arranged on the rotation shaft 109 of the linkage lock 105 to generate an elastic force for resetting the linkage lock 105.

[0059] Specifically, a torsion spring is sleeved on the rotation shaft 109. When the second button 103 drives the protrusion 108 to move towards the first button 102, pushes the second extension arm 116 and drives the first extension arm 115 to rotate around the rotation shaft 109 in a direction away from the effective contact surface 106, the torsion spring is compressed to store elastic potential energy. After releasing the second button 103, the linkage lock 105 rotates in the reverse direction and continues to abut against the locking structure 104.

[0060] As an optional implementation manner, the connecting line between the center point of the rotation shaft 109 and the geometric center of the effective contact surface 106 is parallel to the sliding direction.

[0061] Wherein, the first extension arm 115 is perpendicularly abutted against the effective contact surface 106, and the formed abutting point is close to the side of the locking structure 104.

[0062] It should be noted that the first extension arm 115 of the embodiment of the present application abuts against the part of the locking structure 104 close to the edge, which is convenient for the first extension arm 115 to rotate to be misaligned with the locking structure 104, so as to release the abutment against the effective contact surface 106.

[0063] Wherein, referring to Figure 2 、 Figure 3 and Figure 4 as shown, the first extension arm 115 and the second extension arm 116 are perpendicular to each other; a limiting protrusion 110 is arranged on the main body mounting block 101 between the first extension arm 115 and the second extension arm 116 for limiting the rotation angle of the second extension arm 116.

[0064] It should be noted that the first extension of the embodiment of the present application is perpendicularly arranged with the second extension arm 116 to form a linkage lock 105 with an L-shaped structure. Among them, the limiting protrusion 110 is arranged between the two extension arms of the L-shaped structure, which can limit the pressing depth of the second button 103. In addition, a limiting part for limiting the pressing stroke of the first button 102 is arranged in the main body mounting block 101.

[0065] Different from the above-described embodiments, the linkage locking member 105 is slidably disposed within the main body mounting block 101. The sliding direction of the linkage locking member 105 intersects with the sliding direction of the second button 103. The second button 103 has a guiding inclined surface, and the linkage locking member 105 abuts against the guiding inclined surface. When the second button 103 is pressed and pushed, under the action of the guiding inclined surface, the linkage locking member 105 is pushed to slide away from the effective contact surface 106, so that the structure in contact with the effective contact surface 106 is separated from the effective contact surface 106 after a certain sliding displacement, and the holding force on the first button 102 is released.

[0066] It should be noted that the sliding of the linkage locking member 105 can be realized by the structure of the sliding groove and the sliding block. Among them, the sliding direction of the linkage locking member 105, that is, the extending direction of the sliding groove, is parallel to the effective contact surface 106, and the inclination angle of the guiding inclined surface is set in cooperation with the sliding direction.

[0067] Exemplarily, under the condition of ensuring parallelism with the effective contact surface 106, the sliding direction of the linkage locking member 105 is Figure 4 the up-and-down direction, or is perpendicular Figure 4 to the plane of the paper.

[0068] Among them, since the area of the effective contact surface 106 is limited, the linkage locking member 105 can be separated from the effective contact surface 106 with a certain sliding displacement, so that the volume of the whole structure will not increase.

[0069] In addition, the camera strap provided by the embodiment of the present application includes a strap body for carrying the camera and a quick-release component 100 disposed on the strap body; the strap body is connected to the hanging loop of the camera through a set connection buckle. The camera strap provided by the embodiment of the present application adopts the above-mentioned quick-release component 100, which can allow the camera to be quickly released and immediately enter the shooting state, can prevent accidental touch, and makes the quick-release component 100 safer and more reliable.

[0070] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
