The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0037] like Figure 1-Figure 5 As shown, the utility model provides a self-locking clamping mechanism, including a fixed seat 100, and the fixed seat 100 of the utility model is a rectangular plate. The fixed seat 100 is provided with a first strip-shaped guide groove 101 and a second strip-shaped guide groove 102 of equal length spaced apart and opposite to each other along a first direction. In the utility model, the first guide groove 101 is located at the upper end of the central axis of the fixed seat 100 along the first direction, and the second guide groove 102 is located at the lower end of the central axis of the fixed seat 100 along the first direction.

[0038] It is defined that the direction of relative movement of the right arm 200 and the left arm 300 is a first direction, the surface of the fixing base 100 contacting the product 600 is the front surface, and the direction is forward; the surface of the fixing base 100 facing away from the product 600 is the back surface, and the direction is backward; the direction extending toward the top surface of the product 600 is upward, and the direction extending toward the bottom surface of the product 600 is downward.

[0039] In addition, both side edges of the fixing seat 100 along the first direction extend backward to form a fixing seat side rib 103 , respectively. A plurality of grooves and convex rib structures are symmetrically spaced on each side rib 103 .

[0040] On the back side of the fixing seat 100 , along the four end faces of the rectangular surface, a hollow cylindrical limiting column 104 is symmetrically fixed or integrally formed.

[0041] The right arm 200 and the left arm 300 are arranged opposite to each other along a first direction and are slidably connected to the back side of the fixing base 100 .

[0042] The first guide groove 101 is away from the right arm 200, and the right arm 200 is slidably connected to the first guide groove 101. The second guide groove 102 is away from the left arm 300, and the left arm 300 is slidably connected to the second guide groove 102. This arrangement, on the one hand, fully utilizes the space position on the fixing base 100; on the other hand, makes the center of gravity of the clamping mechanism more stable.

[0043] In addition, when the right arm 200 is slidably connected to the first guide groove 101 and the left arm 300 is slidably connected to the second guide groove 102, the central axes of the right arm 200, the left arm 300 and the fixing base 100 along the first direction are on the same horizontal line.

[0044] like Figure 4-5 As shown, the right arm 200 includes an integrally formed connection plate 201 and a bayonet portion 202, and the bayonet portion 202 is located on one side of the connection plate 201. The connection plate 201 is slidably connected to the first guide groove 101 and is located on the back of the fixing seat 100; the opening of the bayonet portion 202 faces the product 600, and includes a bayonet support plate 2021 perpendicular to the connection plate 201 and an obtuse rib 2022 connected to the bayonet support plate 2021. The design of the oblique rib 2022 increases the opening size of the bayonet portion 202, so that the clamping mechanism can be compatible with products 600 of different thicknesses.

[0045] Preferably, in the present invention, a bayonet portion 202 is symmetrically provided at intervals on both sides of the central axis of the connecting plate 201 along the first direction.

[0046] The connecting plate 201 is divided into an upper end portion of the connecting plate 201 and a lower end portion of the connecting plate 201 by the central axis along the first direction thereof. The upper end portion of the connecting plate 201 is provided with a connecting plate guide groove 2011 along the side edge of the first direction thereof, and the connecting plate guide groove 2011 is slidably connected to the limiting column 104 close thereto. Immediately below the connecting plate guide groove 2011 and at one end away from the bayonet portion 202, a strip-shaped support arm 2013 is extended in a direction away from the bayonet portion 202, and a cylindrical bayonet pin is integrally formed on the top end surface of the support arm 2013 away from the bayonet portion 202, and the bayonet pin is slidably connected to the first guide groove 101.

[0047] Preferably, the support arm 2013 is arc-shaped away from the top of the bayonet portion 202 .

[0048] At the lower end of the connecting plate 201, a connecting plate guide groove 2011 is provided along its side in the first direction. The connecting plate guide groove 2011 is slidably connected to a limiting column 104 close to it, and is concave inwardly toward the bayonet portion 202 just above the connecting plate guide groove 2011 to form a strip-shaped support arm accommodating groove 2015.

[0049] The two connecting plate guide grooves 2011 are of equal length to the first guide groove 101 , and the support arm 2013 is of equal length to the support arm receiving groove 2015 .

[0050] In addition, on the lower end of the connecting plate, on the side below the connecting plate guide groove 2011 and on the top surface of one end away from the bayonet portion 202, one end of an elastic component 400 is connected, and the other end of the elastic component 400 is connected to the fixing seat 100, and a spring connecting column 105 is provided at the connection between the fixing seat 100 and the elastic component 400. The length of the elastic component 400 in the natural state is not greater than the length of the fixing seat 100. The elastic component 400 in the utility model is a stretching spring column, but is not limited thereto, and can have an elastic structural function of stretching and extending, contracting and resetting.

[0051] Preferably, one end of the arm receiving groove 2015 close to the bayonet portion 202 is arc-shaped.

[0052] Furthermore, the connecting plate 201 is located on the central axis of the first direction, and one end away from the bayonet portion 202 is concave inwardly toward the bayonet portion 202 to form a wire groove 2016. Correspondingly, the fixing base 100 is concave inwardly toward both sides along the central axis of the first direction, each forming a wire groove 2016, and the fixing base 100 is provided with a through hole 107 at the center of the central axis of the first direction to facilitate the insertion and removal of the data cable connector.

[0053] like Figure 4-5 As shown, the structure of the left arm 300 and the structure of the right arm 200, the connection relationship between the left arm 300 and the fixing base 100, and the connection relationship between the right arm 200 and the fixing base 100 are all in an upper and lower mirror relationship, which will not be repeated here.

[0054] When the elastic components 400 on the right boom 200 and the left boom 300 are both in a free state, the bayonet on the arm 2013 of the right boom 200 is located in the first guide slot 101 close to one end of the left boom 300, and each limiting column 104 connected to the right boom 200 is located in the corresponding connecting plate guide slot 2011 and away from one end of the left boom 300; the bayonet on the arm 2013 of the left boom 300 is located in the second guide slot 102 close to one end of the right boom 200, and each limiting column 104 connected to the left boom 200 is located in the corresponding connecting plate guide slot 2011. At this time, since the structures of the right arm 200 and the left arm 300 and their respective connection relationships with the fixing seat 100 are in a mirror image relationship, the support arm 2013 of the right arm 200 is placed in the support arm accommodating groove 2015 of the left arm 300, and the support arm 2013 of the left arm 300 is placed in the support arm accommodating groove 2015 of the right arm 200, that is, the connecting plates 201 on the right arm 200 and the left arm 300 are both located in the loading plane of the fixing seat 100, and the bayonet parts 202 on the right arm 200 and the left arm 300 are both located outside the loading plane of the fixing seat 100.

[0055] In addition, on the front surface of the fixing seat 100, along the four end surfaces of its rectangular surface, soft cushions 108 are symmetrically arranged at intervals. The arrangement of the cushions 108, on the one hand, makes the product 600 and the front surface of the fixing seat 100 softly connected when in contact, and enhances the connection between the two, while providing a certain buffering force against external forces; on the other hand, the top surface of the cushion 108 has a height difference with the front surface of the fixing seat 100, and combined with the above-mentioned wire grooves 2016, it plays the role of organizing the data line 700, that is, when the product 600 is placed on the cushion 108, the connector part of the data line 700 adapted to the product 600 passes through the through hole 107, and the wire body of the data line 700 can be sequentially clamped in the cavity formed by the wire groove 2016 and the cushion 108 and the front surface of the fixing seat 100.

[0056] Furthermore, the clamping mechanism is also provided with a bracket cover 500. The bracket cover 500 in the utility model is a rectangular plate. The bracket cover 500 is symmetrically provided with a plurality of ribs and groove structures on both side edges along the first direction, which are respectively engaged and connected with the grooves and ribs on the side guard 103 of the fixing seat, and a cavity is formed between the front surface of the bracket cover 500 and the back surface of the fixing seat 100.

[0057] Preferably, the rear surface of the bracket cover 500 is provided with a step surface on both side edges along the first direction, each of which protrudes outward away from the fixing seat 100. Each step surface is symmetrically provided with a plurality of ribs and groove structures on both side edges along the first direction, which are respectively engaged with the grooves and ribs on the side retaining edge 103 of the fixing seat.

[0058] The cavity formed by each step surface and its corresponding fixing seat side guard 103 is relatively large, and the two elastic components 400 are respectively accommodated therein, while the other cavities formed by the other parts of the bracket cover 500 and the back plate of the fixing seat 100 are relatively small, making the spatial layout of the clamping mechanism more compact and further optimizing the stability of the clamping mechanism during application.

[0059] In addition, the central axis along the first direction of the bracket cover 500 is concave toward both sides, each forming a wire groove 2016, and a through hole B is provided at the center of the central axis along the first direction, and the two wire grooves 2016 on the bracket cover 500 and the fixing base 100 correspond to each other, and the positions of the through hole B of the bracket cover 500 and the through hole 107 correspond to each other, so as to facilitate the organization and accommodation of the data cable 700.

[0060] In order to further stabilize the connection between the bracket cover 500 and the fixing base 100, a connecting hole is provided on each of the four end faces along the rectangular surface of the bracket cover 500. The positions of the four connecting holes correspond one-to-one to the positions of the four limiting columns 104 on the fixing base 100. Each connecting hole is inserted into the hollow cavity of the corresponding limiting rod 104 through a clamping rod to achieve fixed connection between the bracket cover 500 and the fixing base 100.

[0061] Furthermore, the back surface of the bracket cover 500 can be fixedly connected with various types of brackets, so that the product 600 can be supported on a desktop, a wall, or a car center console. Specifically, the back surface of the bracket cover 500 is symmetrically and spaced apart with a plurality of bracket connection holes 501, and the bracket can be engaged in the bracket connection holes 501; preferably, each bracket connection hole 501 is provided with an internal thread, and the bracket can be threadedly connected with each bracket connection hole 501. In the utility model, the back surface of the bracket cover 500 is symmetrically and spaced apart with 6 bracket connection holes 501.

Taking pulling the right arm 200 as an example, the right arm 200 moves along the first guide groove 100 away from the fixed seat 100. At the same time, the two connecting plate guide grooves 2011 on the right arm 200 also synchronously move relative to their corresponding limit columns 104 away from the fixed seat 100, so as to increase the distance between the upper snap-in portion 202 of the right arm 200 and the upper snap-in portion 202 of the left arm 300; when pulling the left arm 300, its moving direction is opposite to that of the right arm 200, but the movement process is similar and will not be repeated here. In this way, the clamping mechanism is compatible with products of different sizes;

[0065] S3, data cable integration, the connector of the data cable 700 compatible with the product 600 can pass through the through holes of the fixing base 100 and the bracket cover 500, and connect the plug, and the body of the data cable 700 is sequentially organized in the cavity between the soft pad 108 and the fixing base 100 and any wire groove 2016.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
