[0041] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following description, with reference to the accompanying drawings, describes a connecting device 100 according to an embodiment of the present invention, which includes a connector 1, an assembly 2, and a drive component 3.

[0043] like Figure 1-19 As shown, the connecting device 100 according to an embodiment of the present utility model includes a connector 1, an assembly 2, and a driving component 3.

[0044] The connector 1 has a mounting cavity 11 and an opening 12 that communicate with each other, the mounting cavity 11 being along the length direction of the connector 1 (e.g., Figure 1 The opening 12 extends through the connector 1 in the left-right direction (as shown), and extends along one side of the connector 1 and along the width direction of the connector 1. Specifically, as shown... Figure 1 , Figure 2 ,and Figure 3 and Figure 7 As shown, the connector 1 can be inserted between two splicing parts 7. The mounting cavity 11 penetrates the cavity of the shell in the left and right direction. The left side or right side of the connector 1 is provided with an opening 12, and the opening 12 communicates with the mounting cavity 11.

[0045] The assembly 2 is disposed within the opening 12 and is rotatable relative to the connector 1 between a first position and a second position. In the first position, the assembly 2 is located within the opening 12, and in the second position, at least a portion of the assembly 2 is located outside the opening 12. Specifically, as... Figure 1 As shown, the assembly 2 is located inside the opening 12 and can rotate around the connector 1 in the left and right directions. In the first position, the assembly 2 is located inside the opening 12, which facilitates the installation of the connector 1 between the two splicing parts 7. In the second position, the assembly 2 rotates to the outside of the opening 12 and abuts against the splicing parts 7, so that the two splicing parts 7 are connected by the connecting device 100.

[0046] The driving component 3 is located within the mounting cavity 11 and is movable between a third position and a fourth position along the length of the connecting component 1. When the driving component 3 is in the third position, the assembly 2 is in the first position. When the driving component 3 is in the fourth position, the driving component 3 drives the assembly 2 to rotate, thereby driving the assembly 2 to the second position. Specifically, as shown... Figures 9-12As shown, the driving component 3 is a horizontal rod extending in the left and right direction. The driving component 3 is located in the mounting cavity 11 and can move between the third position and the fourth position in the left and right direction within the mounting cavity 11. When the driving component 3 moves to the third position, the mounting part 2 is located in the first position. In the fourth position, the driving component 3 drives the mounting part 2 to rotate outward so that the driving component 3 rotates to the second position, thereby causing the driving component 3 to abut against the inner circumferential surface of the splicing part 7, so that the connecting device 100 is fixed between the two splicing parts 7, thereby connecting the two splicing parts 7 through the connecting device 100.

[0047] The connecting device 100 of this utility model embodiment is provided with a connector 1, an assembly 2 and a driving member 3. When it is necessary to install the connecting device 100 between the splicing parts 7, the driving member 3 drives it to a third position, so that the assembly 2 is located in the opening 12, so as to facilitate the installation of the connecting device 100 between the splicing parts 7. When it is necessary to install the connecting device 100 between the splicing parts 7, the driving member 3 drives the assembly 2 to rotate outward from the opening 12 so that the assembly 2 is tightly connected with the splicing parts 7, thereby improving the connection stability of the connecting device 100.

[0048] In some embodiments, the assembly 2 includes a first plate 21, a second plate 22, and a rotating shaft 23. The rotating shaft 23 passes through the opening 12, and the first plate 21 and the second plate 22 are rotatably mounted on the rotating shaft 23. In a first position, both the first plate 21 and the second plate 22 are located within the opening 12. In a second position, at least one of the first plate 21 and the second plate 22 protrudes outside the opening 12. Specifically, as... Figures 4-6 As shown, the rotating shaft 23 is a horizontal shaft extending in the left and right direction and passes through the opening 12. The first plate 21 and the second plate 22 can both be passed through the rotating shaft 23 by torsion springs 8. The torsion springs 8 give the first plate 21 and the second plate 22 an elastic force to rotate from the second position to the first position, and rotate around the rotating shaft 23 in the opening 12. In the first position, the first plate 21 and the second plate 22 are both located in the opening 12. In the second position, the first plate 21 and the second plate 22 rotate outward under the drive of the driving member 3, so that the first plate 21 and the second plate 22 both extend out of the opening 12 and abut against the splicing member 7. Thus, the stability of the connection of the connecting device 100 can be improved by setting the first plate 21 and the second plate 22.

[0049] In some embodiments, the cross-sectional area of ​​the first plate 21 gradually increases in the direction away from the second plate 22, and / or, the cross-sectional area of ​​the second plate 22 gradually increases in the direction away from the first plate 21. Specifically, as Figure 4As shown, the first plate 21 is a wedge-shaped plate with a cross-sectional area that gradually decreases from top to bottom, and the second plate 22 is a wedge-shaped plate with a cross-sectional area that gradually increases. The lower end of the first plate 21 passes through the rotating shaft 23, and the upper end of the second plate 22 passes through the rotating shaft 23. Thus, the first plate 21 and the second plate 22 gradually rotate outward. The increase in cross-sectional area ensures a tight fit with the splicing component 7. The wedge design optimizes the space utilization inside the connecting device 100. When the first plate 21 and the second plate 22 rotate to the second position, their gradually increasing cross-sectional area fills more space, reduces the gaps inside the connecting device 100, and improves the overall compactness and stability.

[0050] In some embodiments, the connecting device 100 further includes a first rubber plate 24 and a second rubber plate 25, wherein the first rubber plate 24 is disposed on the side of the first plate 21 away from the driving member 3, and the second rubber plate 25 is disposed on the side of the second plate 22 away from the driving member 3. Specifically, as Figure 4 As shown, a first rubber plate 24 is disposed on the outer peripheral surface of the first plate 21, and a second rubber plate 25 is disposed on the outer peripheral surface of the second plate 22. The cross-sectional area of ​​the first rubber plate 24 is larger than that of the first plate 21, and the cross-sectional area of ​​the second rubber plate 25 is larger than that of the second plate 22. When the first plate 21 and the second plate 22 are in the second position, the first rubber plate 24 and the second rubber plate 25 abut against the splicing component 7 through the first plate 21 and the second plate 22. Due to the softness and elasticity of the first rubber plate 24 and the second rubber plate 25, they can adapt to the surface shape of the splicing component 7, providing a tight fit and better friction. Furthermore, the first rubber plate 24 and the second rubber plate 25 can also absorb vibration and impact during the connection process, further protecting the connecting device 100 and the splicing component 7 from damage.

[0051] In some embodiments, the connector 1 includes a first shell 13 and a second shell 14, which are disposed opposite to each other along the width direction of the connector 1, and a mounting cavity 11 is formed between the first shell 13 and the second shell 14. Specifically, as Figure 15 As shown, the first shell 13 and the second shell 14 are both L-shaped and identical in shape. The first shell 13 and the second shell 14 are arranged opposite each other in the front-back direction and are fixedly connected by adhesive. The first shell 13 and the second shell 14 are in a 180° rotational combination relationship. The inner circumferential surface of the first shell 13 and the inner circumferential surface of the second shell 14 define the mounting cavity 11. Thus, by setting the first shell 13 and the second shell 14, the assembly part 2 and the driving part 3 can be pre-installed between the connecting part 1, thereby improving the assembly efficiency of the connecting device 100 and reducing the assembly difficulty.

[0052] In some embodiments, there are multiple openings 12, which are spaced apart circumferentially along the connector 1. There are also multiple fittings 2, each corresponding to one of the multiple openings 12. Specifically, as shown... Figure 1As shown, there are two openings 12, one opening 12 is formed on the front side of the connector 1, and the other opening 12 is formed on the rear side of the connector 1. There are also two fittings 2, which are installed in the two openings 12 respectively. The driving member 3 is located between the two fittings 2 to drive the two fittings 2 to rotate between the first position and the second position, so that the two fittings 2 simultaneously pass through the connector 1 to abut against the splicing member 7, thereby improving the connection efficiency of the connecting device 100.

[0053] In some embodiments, the connecting device 100 further includes a drive plate 4, which is disposed within the mounting cavity 11 and passes through the drive member 3. The drive plate 4 cooperates with the drive member 3 to allow the drive member 3 to drive the drive plate 4 to move relative to the mounting cavity 11 along the length direction of the mounting cavity 11. The drive plate 4 includes a first connecting plate 41 and a second connecting plate 42 connected to each other. In a projection plane orthogonal to the length direction of the connecting member 1, the first connecting plate 41 is located on the side of the second connecting plate 42 away from the inner circumferential surface of the mounting cavity 11. When the drive member 3 is in a third position, the second connecting plate 42 abuts against the mounting part; when the drive member 3 is in a fourth position, the first connecting plate 41 abuts against the mounting part, so that the drive member 3 drives the mounting part to rotate via the drive plate 4. Specifically, as shown... Figure 6 and Figure 15 As shown, the right end of the first connecting plate 41 is connected to the left end of the second connecting plate 42. The first connecting plate 41 is located at the front end of the second connecting plate 42. The driving member 3 is connected to the driving plate 4 to drive the driving plate 4 to move in the left and right direction. When the driving member 3 drives the driving plate 4 to the third position, the second connecting plate 42 abuts against the first plate 21 and the second plate 22, so that the connecting device 100 can be installed between the two splicing pieces 7. When the driving member 3 drives the driving plate 4 to the fourth position, the first connecting plate 41 abuts against the first plate 21 and the second plate 22, so that the first connecting plate 41 drives the first plate 21 and the second plate 22 to rotate outward, so that the first plate 21 and the second plate 22 abut against the two splicing pieces 7.

[0054] In some embodiments, the driving member 3 includes a threaded rod 33, a nut 34, a first limiting portion 35, and a second limiting portion 36. The first limiting portion 35 and the second limiting portion 36 are both disposed on the threaded rod 33 and spaced apart along the length of the threaded rod 33. The nut 34 is threadedly engaged with the threaded rod 33 and located on the side of the first limiting portion 35 away from the second limiting portion 36. A slot 15 is provided in the mounting cavity 11, and the nut 34 is engaged in the slot 15 to allow rotation of the threaded rod 33 to move within the mounting cavity 11. A driving plate 4 is disposed between the first limiting portion 35 and the second limiting portion 36 so that the driving member 3 can drive the driving plate 4 to move via the first limiting portion 35 and the second limiting portion 36. Specifically, as shown... Figure 2 , Figure 6 , Figure 13 and Figure 14As shown, the threaded rod 33 extends in the left-right direction. The first limiting part 35 and the second limiting part 36 are both provided on the threaded rod 33 and fixed on the threaded rod 33. The first limiting part 35 and the second limiting part 36 are spaced apart in the left-right direction. The nut 34 is threaded through the threaded rod 33 and is located between the first limiting part 35 and the second limiting part 36. The inner circumferential surface of the connector 1 is provided with a groove 15. The nut 34 is engaged in the groove 15, so that the nut 34 cannot rotate or move in the groove 15. The drive plate 4 is located between the first limiting part 35 and the second limiting part 36 and is connected to the first limiting part 35 and the second limiting part 36, thereby driving the drive plate 4 to move left and right.

[0055] In some embodiments, the driving member 3 is a threaded rod 33, and the driving plate 4 has a threaded hole that passes through the driving plate 4 along the length direction of the connecting member 1. The threaded rod 33 passes through the threaded hole and is threadedly engaged with the threaded hole so that rotating the threaded rod 33 drives the driving plate 4 to move. Specifically, as shown in the figure Figure 15 — Figure 17 As shown, a groove 15 is provided on the inner circumferential surface of the connector 1, and the left end of the threaded rod 33 passes through the groove 15, which allows the threaded rod 33 to rotate in the connector 1, thereby driving the drive plate 4 to move in the left and right directions.

[0056] In some embodiments, the opening 12 includes a first opening and a second opening, both formed on the connector 1 and spaced apart along the length of the connector 1. The mounting part 2 includes a first mounting part 26 and a second mounting part 27, the first mounting part 26 being disposed within the first opening and the second mounting part 27 being disposed within the second opening. The driving member 3 includes a first driving member and a second driving member, both disposed within the mounting cavity 11 and spaced apart from each other along the length of the connector 1. Both the first driving member and the second driving member are movable between a third position and a fourth position along the length of the connector 1. Specifically, as shown... Figures 13-19 As shown, the first opening and the second opening are spaced apart on the connector 1 in the left-right direction. The first assembly 26 is located in the first opening, and the second assembly 27 is located in the second opening. The first driving member and the second driving member are spaced apart in the mounting cavity 11 in the left-right direction, and both the first driving member and the second driving member can move between the third position and the fourth position in the left-right direction. The driving plate 4 includes a first driving plate 43 and a second driving plate 44. The first driving member passes through the first driving plate 43 to drive the first assembly 26 to move outside the first opening, and the second driving member passes through the second driving plate 44 to drive the second assembly 27 to move outside the second opening. Thus, when the length of the splicing piece 7 is too long, the first driving member and the second driving member can be driven simultaneously to drive the first assembly 26 and the second assembly 27 to abut against the splicing piece 7, thereby connecting the left and right ends of the splicing piece 7 and improving the connection efficiency.

[0057] In some embodiments, such as Figure 14 and Figure 17 As shown, the first driving member and the second driving member can be integrally formed, so that by driving one of the first driving member and the second driving member, the first assembly 26 and the second assembly 27 can be driven to move in the inward and outward directions.

[0058] In some embodiments, such as Figure 19 As shown, the first drive plate 43 and the second drive plate 44 can be integrally formed. Thus, the first drive plate 43 and the second drive plate 44 can be driven to move synchronously in the left and right direction within the connector 1 by a single drive member 3, so that the first drive plate 43 and the second drive plate 44 synchronously drive the first assembly 26 and the second assembly 27 to rotate.

[0059] In some embodiments, the connecting device 100 further includes a first cover plate 5 and a second cover plate 6, which are detachably disposed at both ends of the connecting member 1, so that the first cover plate 5 and the second cover plate 6 seal the mounting cavity 11. Specifically, as Figure 15 As shown, the first cover plate 5 and the second cover plate 6 are both vertical plates and the outline shape of the first cover plate 5 and the second cover plate 6 matches the shape of the mounting cavity 11. The first cover plate 5 and the second cover plate 6 can be snapped into the connector 1 to prevent accidental contact with the drive rod, or the first cover plate 5 and the second cover plate 6 can be removed from the connector 1, and the drive member 3 can be twisted to move between the third position and the fourth position.

[0060] In some embodiments, the connector 1 includes a first part and a second part. The first part is disposed on the second part and is symmetrically arranged in the vertical direction. In a projection plane orthogonal to the length direction of the connector 1, the projections of the first part and the second part are both isosceles trapezoids. The first part and the second part are arranged opposite each other in the vertical direction. Specifically, as shown... Figure 1 and Figure 7 As shown, since there is a mounting cavity 11 between each of the two adjacent splicing parts 7, the inner circumferential surface shape of the mounting cavity 11 matches the outer circumferential surface shape of the connector 1, and the isosceles trapezoidal shape can ensure the precise alignment of the first part and the second part during splicing, reduce splicing errors, improve the accuracy of the overall component, and the isosceles trapezoidal shape can provide multiple contact points to ensure multi-point contact between the connector 1 and the mounting cavity 11, thereby improving the stability and reliability of the connection.
