Description

Technical Field

[0001] This utility model relates to the technical field of chain guide rails, specifically to a composite chain transmission guide rail. Background Technology

[0002] A chain guide is a device used to support and guide the movement of a chain. Its main functions are as follows:

[0003] First, it reduces friction between the chain and the equipment surface, lowering wear and extending the chain's lifespan. Second, it ensures the chain runs along a specific path and direction, improving transmission efficiency and making chain operation more precise and stable. Chain guides are made from various materials, with ultra-high molecular weight polyethylene (UHMWPE) being a common choice. This material has excellent wear resistance and self-lubricating properties, making it adaptable to different working environments. It is widely used in automated production lines, conveyor equipment, food processing machinery, and many other fields.

[0004] The chain guide rail has pre-drilled mounting holes for both flat and suspended mounting using screws. The mounting openings are typically located on the inner bottom surface of the rail, requiring a rectangular mounting groove to ensure proper chain installation while preventing subsequent screws from obstructing the chain. For side mounting, an outer panel extends outwards to align with the surface of external equipment. However, this design presents a problem:

[0005] When the existing chain guide rail is fixed by screws, the mounting groove on the inner side is a rectangular groove with equal width at the top and bottom, which is not conducive to the convenient installation and removal of screws in actual operation. When the chain guide rail is fixed by side mounting, the overall stability of the chain guide rail needs to be improved after the guide rail is installed by extending the outer side panel to fit the plane of the external equipment.

[0006] Therefore, this utility model proposes a composite chain transmission guide rail. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a composite chain transmission guide rail that can solve the following problems:

[0008] When using screws for installation and fixing, the existing mounting grooves on the inner side of the chain guide are rectangular grooves with equal width at the top and bottom, which makes it difficult to easily install and remove the screws in actual operation.

[0009] When side-mounting the chain guide rail, after the guide rail is installed by extending the outer side panel to fit the plane of the external equipment, the overall stability of the chain guide rail needs to be improved.

[0010] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0011] A composite chain transmission guide rail includes a guide rail body, a guide groove is formed on the inner side of the guide rail body, a chain is embedded in the guide groove, a surrounding plate assembly is formed on the outer side of the guide rail body, and extension components are fixedly connected to both sides of the bottom end of the surrounding plate assembly. An installation groove is formed in the guide groove. The surrounding plate assembly includes an integrally formed outer plate, a first limiting part and a second limiting part. The extension components include an integrally formed upper clamping layer and a lower clamping layer.

[0012] Furthermore, multiple sets of installation slots are equidistantly opened along the bottom surface of the guide slot, and the top of the installation slot is trapezoidal, while the bottom is rectangular and vertical. The top of the installation slot and the guide slot are inclined inwards at the junction.

[0013] Furthermore, the outer plate surrounds the main body of the guide rail, and two sets of first limiting parts extend inward in a rectangular shape, located on both sides of the inner side of the outer plate, which are simultaneously embedded in the surface of the main body of the guide rail.

[0014] Furthermore, the second limiting part is trapezoidally protruding inward, located at the top two corners of the outer perimeter plate.

[0015] Furthermore, slots are provided on both sides of the guide rail body corresponding to the first limiting part, and the top two corners of the guide rail body are set in inclined grooves corresponding to the second limiting part.

[0016] Furthermore, the extension components are provided in two sets, one set is arranged horizontally outward, and the other set is arranged vertically outward. The upper and lower pressing layers are integrated in a "U" shape, and both surfaces are provided with screw holes. The surface of the lower pressing layer is also arranged in a trapezoidal concave shape.

[0017] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves the effect of facilitating the installation and fixing of external fixing screws in the guide slot by installing a slot.

[0019] 2. This utility model achieves the effect of surrounding and protecting the guide rail body from the outside through the outer plate, and ensures the stability of the connection between the outer plate and the guide rail body through the first limiting part and the second limiting part.

[0020] 3. This utility model achieves the effect of facilitating the installation and fixation of the guide rail body on the external plane from the horizontal and vertical positions by extending the component. The upper and lower clamping layers, which are integrally formed, can effectively ensure the installation stability between the extension component as a whole and the external equipment plane.

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] See Figure 1-3 As shown, a composite chain transmission guide rail includes a guide rail body 1. A guide groove 5 is provided on the inner side of the guide rail body 1. A chain 2 is embedded in the guide groove 5. A surrounding plate assembly 3 is provided on the outer side of the guide rail body 1. Extension components 4 are fixedly connected to the bottom two sides of the surrounding plate assembly 3. An installation groove 6 is provided in the guide groove 5. The surrounding plate assembly 3 includes an integrally formed outer plate 7, a first limiting part 10 and a second limiting part 11. The extension component 4 includes an integrally formed upper pressing layer 8 and a lower pressing layer 9.

[0029] In this embodiment of the utility model, multiple sets of mounting slots 6 are equidistantly opened along the bottom surface of the guide slot 5, and the top of the mounting slots 6 is trapezoidal and the bottom is rectangular and vertical. The top of the mounting slots 6 and the guide slot 5 are inclined inward at the junction. The mounting slots 6 facilitate the installation and fixing of external fixing screws in the guide slots 5.

[0030] When using external screws to install and fix the guide rail body 1, the top position of the trapezoidal mounting slot 6 provides a larger screw installation space, which facilitates the user to quickly complete the connection and fixation of the guide rail body 1 and the external plane with the screws, as well as subsequent disassembly and assembly operations, while avoiding obstruction to the installation and use of the chain 2.

[0031] The outer plate 7 completely surrounds the guide rail body 1. Two sets of first limiting parts 10 extend inward in a rectangular shape and are located on the inner sides of the outer plate 7. They are embedded in the surface of the guide rail body 1. The second limiting part 11 protrudes inward in a trapezoidal shape and is located at the top corners of the outer plate 7. Slots are opened on both sides of the guide rail body 1 corresponding to the first limiting part 10. The top corners of the guide rail body 1 are inclined grooves corresponding to the second limiting part 11. The outer plate 7 achieves the effect of surrounding and protecting the guide rail body 1 from the outside. The first limiting part 10 and the second limiting part 11 ensure the stability of the connection between the outer plate 7 and the guide rail body 1.

[0032] The first limiting part 10 and the second limiting part 11 ensure the connection stability between the guide rail body 1 and the outer plate 7 from the top two sides and the outer side, respectively, which is conducive to the subsequent installation and fixing of the guide rail and ensures its installation stability.

[0033] The extension component 4 is provided in two sets, one set is set out horizontally outward, and the other set is set out vertically outward. The upper clamping layer 8 and the lower clamping layer 9 are set in a "U" shape as a whole. Both of them have screw holes on their surfaces. The surface of the lower clamping layer 9 is also set in a trapezoidal concave shape. The extension component 4 achieves the effect of facilitating the installation and fixation of the guide rail body 1 on the external plane from the horizontal and vertical positions. The integrated upper clamping layer 8 and the lower clamping layer 9 can effectively ensure the installation stability between the extension component 4 as a whole and the external equipment plane.

[0034] When the chain guide rail is side-mounted and fixed, a set of extension components 4 can be made to be horizontally attached to the surface of the external equipment according to the actual installation requirements. Then, the extension components 4 are fixed by external screws. The upper clamping layer 8 and the lower clamping layer 9 are pressed against each other when fixed by external screws, which can effectively ensure the installation stability of the extension components 4.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
