DETAILED DESCRIPTION

[0051] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0052] The connection assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

Figure 1 The housing 1 is provided with a mounting hole 12 (in the vertical direction shown in the figure), and the chamber 11 includes a first portion 111 and a second portion 112 sequentially arranged along the length direction of the housing 1. The first portion 111 and the second portion 112 are connected, and the first portion 111 is connected to the mounting hole 12. Specifically, as shown in FIG. Figure 2 , Fig.13 and Fig.21 As shown, the shell 1 can be inserted between the two splicing pieces 6, the chamber 11 penetrates the cylindrical chamber 11 of the shell 1 along the left-right direction, the first part 111 and the second part 112 are arranged in sequence along the left-right direction, and the mounting hole 12 is a rectangular hole formed on the outer peripheral surface of the shell 1, and the first part 111 and the second part 112 are both connected to the mounting hole 12.

[0055] The mounting member 2 is disposed in the first portion 111 and at least a portion of the mounting member 2 can be disposed in the first portion 111 along the width direction of the housing 1 (eg Figure 1 Specifically, as shown in the figure, Figure 2 , Figure 3 , Fig.13 and Fig.14 As shown, the mounting member 2 is a spring sheet and extends in the left-right direction. One end of the mounting member 2 is arranged in the first part 111 and the other end of the mounting member 2 is arranged opposite to the mounting hole 12 in the up-down direction. The other end of the mounting member 2 can extend into the mounting hole 12.

[0056] The elastic member 3 is disposed in the mounting hole 12 and is located on a side of the mounting member 2 away from the chamber 11, and at least a portion of the elastic member 3 is disposed opposite to the mounting member 2 along the width direction of the housing 1. Specifically, Figure 1-Figure 3 , Figure 8-Figure 12 As shown, the elastic member 3 is a rubber member and extends in the left-right direction. The elastic member 3 is arranged in the mounting hole 12 and the left and right ends of the elastic member 3 are fixed to the left and right ends of the mounting hole 12 by adhesive. At least a portion of the elastic member 3 is arranged relative to the mounting member 2 in the up-down direction and the inner circumferential surface of the elastic member 3 is in contact with the outer circumferential surface of the mounting member 2.

[0057] The driving member 4 is disposed in the chamber 11 and is movable between a first position and a second position along the extension direction of the chamber 11. The driving member 4 includes a first section 41 and a second section 42 connected in sequence. The cross-sectional area of ​​the first section 41 is greater than the cross-sectional area of ​​the second section 42. In the first position, the first section 41 is located in the second portion 112. In the second position, the first section 41 is located in the mounting member 2. The first section 41 drives the mounting member 2 to move in a direction away from the chamber 11, and the mounting member 2 drives the elastic member 3 to move in a direction away from the chamber 11. Specifically, as Figure 5-Figure 8 and Figure 16-Figure 19 As shown, the driving member 4 is a rod extending in the left-right direction and has a first section 41 and a second section 42 connected in sequence. The cross-sectional area of ​​the first section 41 is larger than the cross-sectional area of ​​the second section 42. The driving member 4 can be moved between the first position and the second position in the left-right direction. When the connecting assembly 100 needs to be installed between the two splicing members 6, as shown in FIG. Figure 5 , Figure 6 As shown, Fig.14 and Fig.15 As shown, the driving member 4 is in the first position, the first section 41 is located in the second portion 112, the second section 42 is located in the mounting member 2, and the elastic member 3 is located in the mounting hole 12, so that the connecting assembly 100 is conveniently installed between the two splicing members 6. When the friction between the connecting assembly 100 and the splicing member 6 needs to be increased, as shown in FIG. Figure 7 , Figure 8 As shown, Fig.18 and Fig.19As shown, the driving member 4 is in the second position, the first section 41 is located in the mounting member 2, and the second section 42 is located in the second portion 112, so that the first section 41 drives the mounting member 2 to move from the inside to the outside toward the mounting hole 12, and the mounting member 2 drives the elastic member 3 to expand from the inside to the outside so that the elastic member 3 extends out of the mounting hole 12 and presses tightly between the splicing members 6, so that the elastic member 3 fills between the two splicing members 6.

[0058] The connecting component 100 of the embodiment of the present invention is provided with a shell 1, a mounting member 2, an elastic member 3 and a driving member 4. When the connecting component 100 needs to be installed between the splicing members 6, the driving member 4 drives the elastic member 3 to shrink into the mounting hole 12 to facilitate the installation of the connecting component 100 between the splicing members 6. When the connecting component 100 needs to be installed on the splicing members 6, the driving member 4 drives the elastic member 3 to expand out of the mounting hole 12 to make the elastic member 3 tightly combined with the splicing members 6, thereby improving the connection stability of the connecting component 100.

[0059] In some embodiments, the mounting member 2 includes a first plate 21 and a plurality of second plates 22, the first plate 21 extends along the circumference of the housing 1, the second plate 22 extends along the length direction of the housing 1, the plurality of second plates 22 are arranged at one end of the first plate 21 and are arranged at intervals along the extension direction of the second plate 22, the first plate 21 is arranged in the first portion 111, and in the second position, the first section 41 drives the plurality of second plates 22 to move toward the direction adjacent to the elastic member 3. Specifically, as Figure 2 As shown, the first plate 21 is an arc-shaped plate extending along the circumference of the chamber 11, and the second plate 22 is an arc-shaped plate extending along the left-right direction. The first plate 21 can be fixed on the inner circumference of the chamber 11, and the number of the second plates 22 is three (such as Figure 2 3), three second plates 22 are arranged at intervals along the circumference of the first plate 21. In the second position, the first section 41 is located between the multiple second plates 22, and the first section 41 pushes the second plate 22 to move toward the mounting hole 12, so that the second plate 22 transmits the driving force of the first section 41, and the second plate 22 drives the elastic member 3 to expand, thereby increasing the expansion area of ​​the elastic member 3, increasing the contact area between the connecting component 100 and the two splicing parts 6, and improving the stability of the connection between the connecting component 100 and the two splicing parts 6.

[0060] In some embodiments, the housing 1 further comprises a mounting portion 16, the mounting portion 16 is disposed in the first portion 111, and the mounting member 2 is disposed on the mounting portion 16. Figure 2 and Fig.13As shown, the mounting portion 16 is a mounting plate extending in the front-to-back direction, and the front and rear ends of the mounting portion 16 are fixed on the front and rear sides of the first portion 111. An arc groove penetrating the mounting portion 16 in the left-right direction is provided on the side of the mounting portion 16 away from the elastic member 3, and the first plate 21 is bonded or welded in the arc groove, thereby providing a mounting base for the mounting member 2 through the mounting portion 16, thereby improving the installation stability of the mounting member 2.

[0061] In some embodiments, a mounting groove 31 is provided on the side of the elastic member 3 facing the chamber 11, at least a portion of the mounting portion 16 is inserted into the mounting groove 31, and a side of the elastic member 3 away from the chamber 11 is flush with the outer peripheral surface of the housing 1. Figure 3 and 14 As shown, a rectangular mounting groove 31 extending in the front-to-back direction is provided on the inner circumferential surface of the elastic member 3. When the elastic member 3 is installed in the mounting hole 12, the mounting portion 16 is installed in the mounting groove 31 on the side away from the chamber 11. Therefore, through the cooperation of the mounting groove 31 and the mounting portion 16, the elastic member 3 can be positioned in the left-right direction. The outer circumferential surface of the elastic member 3 is flush with the outer circumferential surface of the shell 1. Therefore, when the connecting component 100 is installed between the two splicing pieces 6, collision or friction between the elastic member 3 and the splicing pieces 6 can be prevented, thereby reducing the wear of the elastic member 3, facilitating the installation of the connecting component 100, and ensuring the durability and reliability of the elastic member 3.

[0062] In some embodiments, the housing 1 includes a first shell 13 and a second shell 14 symmetrical to each other, and a mounting frame 15 .

[0063] The chamber 11 includes a first sub-chamber and a second sub-chamber, the first sub-chamber is formed in the first shell 13, the second sub-chamber is formed in the second shell 14, and the mounting hole 12 is formed in at least one of the first shell 13 and the second shell 14. Specifically, as Figure 2 and Fig.13 As shown, the first shell 13 is arranged above the second shell 14 and the first shell 13 and the second shell 14 are arranged opposite to each other in the up and down directions, the first sub-cavity is formed on the lower end surface of the first shell 13, and the second sub-cavity is formed on the upper end surface of the second shell 14. When the first shell 13 and the second shell 14 are buckled into a whole, the first sub-cavity and the second sub-cavity form a chamber 11, and the number of mounting holes 12 can be set according to actual conditions. For example, the number of mounting holes 12 is two, one of which is formed on the first shell 13, and the other is formed on the second shell 14. The number of elastic members 3 is also two and they are respectively installed in the two mounting holes 12. Through the arrangement of the first shell 13 and the second shell 14, the installation of the elastic member 3 and the mounting member 2 can be facilitated, so that the shell 1 is arranged more reasonably.

[0064] The mounting frame 15 is disposed on one side of the housing 1, and one end of the first shell 13 and one end of the second shell 14 are both disposed on the mounting frame 15. Figure 2and Fig.13 As shown, the outer contour of the mounting frame 15 is consistent with the outer contour of the shell 1 and there are two mounting frames 15, which are respectively arranged at the left and right ends of the first shell 13 and the second shell 14, and the left and right ends of the first shell 13 and the second shell 14 are respectively welded to the mounting frames 15, so that the first shell 13 and the second shell 14 form a whole through the mounting frame 15.

[0065] In some embodiments, the connection assembly 100 further includes a locking member 5, which is disposed in the chamber 11 and connected to the driving member 4. The locking member 5 has a locked state and an unlocked state. In the locked state, the locking member 5 is locked in the first position or the second position. In the unlocked state, the locking member 5 moves between the first position and the second position. Specifically, Figure 2-Figure 8 , Figure 13-Figure 19 As shown, the locking member 5 is arranged in the chamber 11 and can be moved in the left and right directions in the chamber 11. The locking member 5 can be welded, bonded or integrally formed with the driving member 4. In the locked state, the locking member 5 drives the driving member 4 to be located at the first position and the second position and the position of the locking member 5 cannot be moved, so that the driving member 4 is fixed at the desired position by the locking member 5 to prevent movement. In the unlocked state, the locking member 5 can drive the driving member 4 to move between the first position and the second position, so that by unlocking and re-locking, the user can flexibly adjust the position of the driving member 4 to meet the needs under different working conditions.

[0066] In some embodiments, the locking member 5 includes a fixing sleeve 51 and a locking rod 52 .

[0067] The fixing sleeve 51 is arranged in the chamber 11. Specifically, Figure 2-Figure 8 , Figure 13-Figure 19 As shown, the fixing sleeve 51 is fixed to one end of the chamber 11 and is fixedly connected to the inner circumference of the chamber 11 by welding or gluing.

[0068] The locking rod 52 is disposed in the chamber 11 and penetrates the fixing sleeve 51. The locking rod 52 is threadedly connected to the fixing sleeve 51 and one end of the locking sleeve is connected to the driving member 4. Figure 2-Figure 8 , Figure 11-Figure 17 As shown, the locking rod 52 extends in the left-right direction and is fixedly connected to the driving member 4. The outer circumference of the locking rod 52 is provided with an external thread, and the inner circumference of the fixing sleeve 51 is provided with an internal thread. The locking rod 52 is inserted into the fixing sleeve 51 and is threadedly matched, so that the locking rod 52 is installed in the chamber 11, and by rotating the locking rod 52, its position in the fixing sleeve 51 can be fine-tuned to ensure accurate locking of the driving member 4 at the first position or the second position. In addition, the threaded connection has good self-locking properties, that is, in the absence of external force, the threaded connection can maintain a locked state to prevent the driving member 4 from accidentally moving.

[0069] It is worth noting that the fixing sleeve 51 may be a nut, and the locking rod 52 may be a bolt.

[0070] In some embodiments, the locking member 5 further includes a cover plate 53, which is detachably mounted on the housing 1 and covers one end of the chamber 11 so as to seal the chamber 11. In the locked state, the cover plate 53 covers the chamber 11 and the locking rod 52 drives the driving member 4 to be located at the first position or the second position. In the unlocked state, the cover plate 53 is separated from the housing 1 so as to drive the locking rod 52 to drive the driving member 4 to move between the first position and the second position. Specifically, as Figure 2 and Fig.13 As shown, the cover plate 53 is a vertical plate and the contour shape of the cover plate 53 is consistent with the shape of the mounting frame 15. The cover plate 53 can be snapped onto the mounting frame 15. In the locked state, the cover plate 53 covers the mounting frame 15 to seal the chamber 11 to prevent accidental touching of the driving rod. In the unlocked state, the cover plate 53 can be removed from the mounting frame 15, and the locking rod 52 can be twisted to move the locking rod 52 between the first position and the second position.

[0071] In some embodiments, there are multiple first parts 111 and second parts 112, and the multiple first parts 111 and second parts 112 are alternately arranged in sequence. There are multiple mounting members 2, and the multiple mounting members 2 are arranged in the multiple first parts 111 in a one-to-one correspondence. There are multiple first sections 41 and second sections 42, and the multiple first sections 41 and second sections 42 are alternately connected. In the first position, the multiple first sections 41 are located in the multiple second parts 112 in a one-to-one correspondence. In the second position, the multiple first sections 41 are located in the multiple mounting members 2 in a one-to-one correspondence. Specifically, Figure 2 and Fig.13 As shown, the number of the first part 111, the second part 112, the mounting member 2 and the first section 41 are all equal. Therefore, through the cooperation of multiple first parts 111, the second part 112, the mounting member 2 and the first section 41, when the driving member 4 is in the second position, the elastic member 3 expands at multiple positions at the same time, thereby increasing the outward expansion area of ​​the elastic member 3, making the connection between the two splicing members 6 more stable, reducing the risk of loosening and falling off at the connection between the splicing member 6 and the connecting assembly 100, and improving the reliability and safety of the connection between the splicing member 6 and the connecting assembly 100.

[0072] In some embodiments, the driving member 4 includes a first driving member 44 and a second driving member 45, both of which are disposed in the chamber 11 and are spaced apart from each other along the length direction of the chamber 11, and both of which are movable between a first position and a second position along the extension direction of the chamber 11 relative to the chamber 11. Specifically, Figure 10-Figure 20As shown, the first driving member 44 is disposed in the left half of the chamber 11, and the second driving member 45 is disposed in the right half of the chamber 11. Through the coordinated action of the two driving members 4, the elastic member 3 expands simultaneously at multiple positions, further enhancing the connection stability of the two splicing members 6.

[0073] In some embodiments, in a projection plane orthogonal to the length direction of the housing 1, the projection of the first shell 13 and the projection of the second shell 14 are both isosceles trapezoids, and the first shell 13 and the second shell 14 are arranged opposite to each other in the up-down direction. Figure 1 and Fig.12 As shown, since there is a mounting cavity between two adjacent splicing pieces 6, the inner circumferential surface shape of the mounting cavity matches the outer circumferential surface shape of the shell 1, and the isosceles trapezoidal shape can ensure the precise docking of the first shell 13 and the second shell 14 during splicing, reduce splicing errors, and improve the accuracy of the overall assembly. In addition, the isosceles trapezoidal shape can provide multiple contact points, ensure multi-point contact between the shell 1 and the mounting cavity, and improve the stability and reliability of the connection.

[0074] In some embodiments, Fig. 22 As shown, the driving rod also includes a transition section 43, which is arranged between the first section 41 and the second section 42 and is connected to the first section 41 and the second section 42, and the cross-sectional area of ​​the transition section 43 gradually decreases from the first section 41 to the second section 42. Thus, the stress concentration point can be reduced by the transition section 43. During the movement of the driving rod, the stress will be evenly distributed along the transition section 43, avoiding the generation of local high stress at the connection, thereby improving the durability and reliability of the driving rod. Secondly, the design of the transition section 43 can ensure the smooth transmission of force between the first section 41 and the second section 42, avoiding fracture or deformation caused by sudden force transmission. In addition, the smooth design of the transition section 43 can reduce the friction and stagnation of the driving rod when it moves in the chamber 11, ensuring the smooth movement of the driving rod.

[0075] In some embodiments, Figure 6 and Figure 7 As shown, when the size of the splicing piece 6 is relatively large, a connecting assembly 100 can be installed at both ends of the splicing piece 6 to ensure the stability of the connection.

[0076] It is worth mentioning that when the connecting component 100 is installed between the two splicing parts 6, the position of the driving member 4 can be adjusted so that the elastic member 3 of the connecting component 100 expands according to the actual situation, and then the adjusted connecting component 100 is installed between the two splicing parts 6, thereby eliminating the trouble of repeated adjustment of the connecting component 100 and improving the connection efficiency of the connecting component 100.

When it is necessary to adjust the angle between the second connecting plate 65 and the splicing piece 6, the angle of the second connecting plate 65 can be adjusted by adjusting the position of the mounting block 641 and the second hole 631, thereby adjusting the connection angle between the two adjacent splicing pieces 6.

[0087] In some embodiments, the fastener passes through the connecting plate and is disposed in the first hole 621 of the connecting shaft 62 and is threadedly engaged with the first hole 621. Thus, the connection of the splicing device is more stable.
