[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides: a corner bracket with a positioning self-locking structure, such as... Figures 1-5 As shown, the device includes a corner bracket body 1 and a matching frame strip 2. Several sets of self-locking components 3 are installed between the corner bracket body 1 and the frame strip 2. The corner bracket body 1 provides the mounting base for the self-locking components 3, enabling angular connections between the frame strips 2. The frame strips 2 and the corner bracket body 1 cooperate to form a complete frame structure. The self-locking components 3 are installed between the corner bracket body 1 and the frame strip 2 to achieve rapid positioning and self-locking, thereby simplifying the installation process and reducing labor and time costs.

[0024] The self-locking assembly 3 includes several sets of positioning holes 31 formed on the side wall of the frame strip 2. An annular groove 32 is formed in the center of each positioning hole 31. A positioning pin 34 is movably installed on the inner side wall of the corner bracket body 1 corresponding to the positioning hole 31. Several sets of auxiliary pins 37, matching the annular groove 32, are movably installed on the outer wall of the positioning pin 34. The positioning hole 31, located on the side wall of the frame strip 2, is the insertion position of the positioning pin 34, serving as a preliminary positioning element. The annular groove 32, located in the center of the positioning hole 31, matches the auxiliary pins 37 and is used to achieve the self-locking function. During assembly, the positioning pin 34 can be inserted into the positioning hole 31. The auxiliary pins 37, movably installed on its outer wall, are compressed and contracted during the insertion of the positioning pin 34. When the auxiliary pin 37 reaches the position of the annular groove 32, it pops out under the action of elasticity and embeds into the annular groove 32, completing the self-locking. This mating structure replaces the traditional screw fastening method, eliminating the need for precise pre-drilling and avoiding the impact of insufficient drilling accuracy on assembly accuracy, significantly improving the reliability of the corner bracket connection.

[0025] Preferably, the inner wall of the corner bracket body 1 is provided with several sets of first circular grooves 33 for mounting positioning pins 34. Each set of positioning pins 34 is connected to the inner wall of the first circular groove 33 by a first spring 35. The first circular groove 33 is used to mount the positioning pins 34 and provides space for the positioning pins 34 to move. The first spring 35 connects the positioning pins 34 to the inner wall of the first circular groove 33 and provides elastic force to the positioning pins 34. During assembly, when the positioning pins 34 are inserted into the positioning holes 31 of the frame strip 2, the first spring 35 is compressed. When the positioning pins 34 reach the appropriate position, the elastic force of the first spring 35 keeps the positioning pins 34 stably in the positioning holes 31, ensuring the accuracy and stability of the positioning.

[0026] Furthermore, each set of positioning pins 34 has several sets of second circular grooves 36 evenly formed around its central axis on its sidewall, each set of auxiliary pins 37 being connected to the inner wall of the second circular groove 36 via a second spring 38. The second circular groove 36 provides movement space for the auxiliary pins 37; the second spring 38 connects the auxiliary pins 37 to the inner wall of the second circular groove 36, providing elastic force to the auxiliary pins 37. During assembly, when the positioning pin 34 is inserted into the positioning hole 31, the auxiliary pin 37 is squeezed by the inner wall of the positioning hole 31. At this time, the second spring 38 is compressed, and the auxiliary pin 37 retracts into the second circular groove 36. When the auxiliary pin 37 reaches the position of the annular groove 32, the elastic force of the second spring 38 causes the auxiliary pin 37 to pop out and embed into the annular groove 32, achieving self-locking between the corner bracket body 1 and the frame strip 2.

[0027] Furthermore, the output ends of each set of locating pins 34 and auxiliary pins 37 are hemispherical, with polished surfaces. This hemispherical structure at the output ends of the locating pins 34 and 37 provides better guidance when the locating pin 34 is inserted into the locating hole 31 and when the auxiliary pin 37 engages with the annular groove 32, allowing for smoother insertion and embedding, reducing resistance and friction during insertion, and minimizing component wear. The polishing further reduces surface roughness, making the locating pins 34 and 37 move more smoothly during operation, improving assembly efficiency and extending component lifespan.

[0028] It is worth noting that the outer wall of the corner bracket body 1 has two sets of rectangular grooves 4, and a fixing plate 5 for fixing the protrusion 7 is movably installed in the middle of each set of rectangular grooves 4. The fixing plate 5 is movably installed in the middle of the rectangular groove 4 and is used to fix the protrusion 7, playing a transitional role in the entire connection structure. When the corner bracket body 1 is assembled with the frame strip 2, the fixing plate 5 can move within the rectangular groove 4. This movable design creates conditions for subsequent use of elastic structures to enhance connection stability, allowing the fixing plate 5 to adaptively adjust according to the position of the frame strip 2, thereby ensuring that the fitting operation between the protrusion 7 and the inner wall of the frame strip 2 can be smoothly achieved.

[0029] Specifically, each set of fixing plates 5 is elastically connected to the corresponding rectangular groove 4 via several sets of third springs 6, which are arranged in a matrix array. The matrix array arrangement allows for the application of a uniform elastic force to the fixing plates 5. This elastic connection method not only buffers the impact force during assembly but also adaptively adjusts the position of the fixing plates 5 through the spring force, compensating for loose fits caused by component processing errors or assembly deviations, thus enhancing the reliability and stability of the connection between the corner bracket body 1 and the frame strip 2.

[0030] More specifically, each set of fixing plates 5 has several sets of protrusions 7 installed on its outer wall, with the output end of each set of protrusions 7 tightly attached to the inner wall of the frame strip 2. During assembly, the output end of the protrusions 7 is tightly attached to the inner wall of the frame strip 2, effectively enhancing the connection strength between the corner bracket body 1 and the frame strip 2 by increasing the contact points and friction with the inner wall of the frame strip 2. When the corner bracket body 1 is assembled with the frame strip 2, the third spring 6 pushes the fixing plate 5 to make the protrusions 7 tightly adhere to the inner wall of the frame strip 2. At this time, the protrusions 7 generate significant friction, preventing the frame strip 2 from sliding relative to the corner bracket body 1, further improving the stability of the connection structure. Simultaneously, the distributed design of multiple protrusions 7 evenly distributes the connection pressure, avoiding excessive local stress and making the entire connection structure more balanced and reliable. The protrusions 7 can be made of wear-resistant rubber, which, through its own elasticity, further enhances the tightness of the fit with the inner wall of the frame strip 2, reducing hard friction during assembly.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
