[0007] Preferably, the chute is open at both ends, and the upper ends of the side walls of the chute are bent inward to form a detour. A gap is left between the detours of the two side walls to form a groove opening on the upper side of the chute. The openings at both ends of the chute allow the fixing block to slide into the chute through the openings at the ends, while the detour serves as a stop to prevent the fixing block from falling out of the groove.

[0008] Preferably, the first connecting portion of the fixed block cooperates with the detour portion, and the second and third connecting portions of the fixed block are fixedly connected to the bottom of the chute. This structure allows the fixed block to be cooperatively connected to the chute, while the proximity of the first connecting portion to the notch of the chute facilitates the rotational connection between the fixed block and the connecting rod.

[0009] Preferably, the detour portion is formed with positioning bumps that limit the front and rear ends of the first connecting portion of the fixed block. The positioning bumps can achieve a quick positioning connection between the fixed block and the chute, and can also limit the fixed block in the chute to prevent it from sliding and deviating along the length of the chute.

[0010] Preferably, the detour portion is formed with a snap-fit ​​groove, and the first connecting portion of the fixing block is snap-fitted with the snap-fit ​​groove. By snapping the snap-fit ​​groove and the first connecting portion together, the connection stability between the fixing block and the slide groove can be further improved, preventing the fixing block from detaching from the slot.

[0011] Preferably, the first connecting portion of the fixing block is provided with a first axial hole for a shaft connecting member to pass through, and the shaft connecting member is rotatably connected to the connecting rod. Utilizing the above structure, a rotatable connection between the first connecting portion and the connecting rod can be achieved.

[0012] Preferably, the connecting assembly further comprises a spacer block, which is disposed between the connecting rod and the first connecting portion of the fixed block and has a second axial hole for the shaft connector to pass through. The spacer block can support the connecting rod, thereby maintaining a gap between the connecting rod and the chute to prevent contact and friction between the two.

[0013] Preferably, a positioning block is formed at the lower end of the cushion block, and a positioning hole is formed on the first connecting portion of the fixing block to cooperate with the positioning block. The positioning block and the positioning hole cooperate with each other to ensure that the cushion block and the fixing block can be fixedly installed to prevent the cushion block from rotating.

[0014] Preferably, the second and third connecting portions of the fixing block are formed with a first groove and a second groove, and the bottom of the chute is provided with a first and a second boss that respectively cooperate with the first groove and the second groove. Furthermore, the first groove and the first boss are provided with mutually aligned connecting through holes, and the second groove and the second boss are provided with mutually aligned waist-shaped grooves. The mutual cooperation between the first groove and the first boss, and the second groove and the second boss, allows for a quick positioning connection between the fixing block and the chute, while further preventing the fixing block from sliding and deflecting along the chute.

DETAILED DESCRIPTION

[0021] The technical solution claimed by the present utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] See also Figures 1 to 5 As shown, the slide and connecting rod connection structure in this embodiment includes a slide 1, a connecting rod 2 and a connecting component for connecting the slide 1 and the connecting rod 2. The connecting component is fixedly connected to the connecting slide 1 and is rotationally connected to the connecting rod 2 at the same time.

[0023] The chute 1 is open at both ends, and the upper end of the side wall of the chute 1 is bent inward to form a detour portion 11. A gap is left between the detour portions 11 on both side walls to form a groove opening 12 on the upper side of the chute 1.

[0024] The connecting assembly includes a fixed block 31 and a spacer block 32. The fixed block 31 includes a first connecting portion 311 that is rotatably connected to the connecting rod 2, and a second connecting portion 312 and a third connecting portion 313 disposed on the front and rear sides of the first connecting portion 311 and fixedly connected to the chute 1. The first connecting portion 311 of the fixed block 31 cooperates with the detour portion 11, while the second connecting portion 312 and the third connecting portion 313 of the fixed block 31 are fixedly connected to the bottom of the chute 1. Utilizing this structure, the fixed block 31 can be connected to the chute 1 in a coordinated manner. Furthermore, the proximity of the first connecting portion 311 to the notch 12 of the chute 1 facilitates the rotational connection between the fixed block 31 and the connecting rod 2. In this embodiment, the detour portion 11 is formed with positioning protrusions 13, which limit the front and rear ends of the first connection portion 311 of the fixed block 31. The positioning protrusions 13 can achieve a quick positioning connection between the fixed block 31 and the chute 1. At the same time, the positioning protrusions 13 can also restrict the fixed block 31 in the chute 1, preventing it from sliding and deviating along the length of the chute 1. At the same time, the detour portion 11 is formed with a snap-fit ​​groove 111, and the first connection portion 311 of the fixed block 31 is snap-fitted with the snap-fit ​​groove. The snap-fitting connection between the snap-fit ​​groove 111 and the first connection portion 311 can further improve the connection stability between the fixed block 31 and the chute 1 and prevent the fixed block 31 from detaching from the notch 12.

[0025] The first connecting portion 311 of the fixed block 31 is provided with a first axial hole 314 for a shaft connecting member to pass through, and the shaft connecting member is rotatably connected to the connecting rod 2. In this embodiment, the shaft connecting member is a rivet. The second connecting portion 312 and the third connecting portion 313 of the fixed block 31 are provided with a first groove 316 and a second groove 317. The bottom of the chute 1 is provided with a first boss 14 and a second boss 15 that respectively match the first groove 316 and the second groove 317. The first groove 316 and the first boss 14 are both provided with mutually aligned connecting through holes 318, and the second groove 317 and the second boss 15 are provided with mutually aligned waist grooves 319. In this embodiment, the first groove 316 and the first boss 14 are riveted together by rivets, and the second groove 317 and the second boss 15 are also riveted together by rivets. The first groove 316 and the first boss 14 as well as the second groove 317 and the second boss 15 cooperate with each other to achieve a quick positioning connection between the fixing block 31 and the slide groove 1, and further prevent the fixing block 31 from sliding and deflecting along the slide groove 1.

[0026] The pad 32 is positioned between the connecting rod 2 and the first connecting portion 311 of the fixed block 31. It defines a second axial hole 321 for the shaft connector. Furthermore, a positioning block 322 is formed at the lower end of the pad 32, while the first connecting portion 311 of the fixed block 31 defines a positioning hole 315 that mates with the positioning block 322. The pad 32 supports the connecting rod 2, maintaining a gap between the connecting rod 2 and the chute 1 to prevent contact and friction between the two.

[0027] In this embodiment, the connection process between the chute 1 and the connecting rod 2 is as follows:

[0028] S1. First, use rivets to rivet the connecting rod 2, the cushion block 32 and the fixing block 31 from top to bottom, and use the rivets as the shaft connection parts to pass through the first shaft connection hole and the second shaft connection hole at the same time.

[0029] S2. Push the fixing block 31 into the opening at the end of the slide groove 1. Since the slide groove 1 and the fixing block 31 are made of metal, they can produce a certain elastic deformation, and the positioning protrusion 13 has a certain curvature. When the first connecting portion 311 conflicts with the positioning protrusion 13, a slightly increased force can cause the positioning protrusion 13 to deform to a certain extent to avoid the fixing block 31, so that the fixing block 31 can be smoothly pushed to the predetermined installation position. Similarly, elastic deformation and avoidance also occur between the first groove 316 and the first boss 14, and between the second groove 317 and the second boss 15.

[0030] S3. Use rivets to rivet the first groove 316 and the first boss 14 and the second groove 317 and the second boss 15 to complete the installation.

[0031] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art may, without departing from the scope of the present invention, utilize the technical content disclosed above to make further possible variations and modifications to the present invention, or to modify the present invention into equivalent embodiments with equivalent variations. Therefore, any equivalent variations made in accordance with the principles of the present invention without departing from the scope of the present invention shall be included within the scope of protection of the present invention.
