Description

Technical Field

[0001] This utility model relates to the technical field of track pulley assembly, specifically to a straightening component for a connecting rod of a lifting push-pull wheel assembly. Background Technology

[0002] A track pulley system refers to a hardware component that provides sliding support on standard profiles, primarily used in structures such as sliding doors and windows. A track pulley system typically includes at least two pulley pairs, connected in series by a connecting rod structure. The connecting rods of track pulley systems are prone to bending and deformation during transportation and installation. A bent connecting rod can cause the track pulley system to operate unevenly and produce various abnormal noises. Straightening the connecting rods during on-site installation is difficult; using spare parts or sending them back to the supplier for replacement is not conducive to installation and use. Therefore, it is necessary to provide a straightening component to overcome the bending problem of the connecting rods. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a straightening component for a lifting push-pull wheel assembly that is structurally reasonable and easy to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The present invention discloses a straightening component for a connecting rod of a lifting push-pull wheel assembly, comprising a body, a slot on the body, and an opening on the upper end face of the body, the opening communicating with the slot, allowing the connecting component to pass through the opening and be inserted into the slot; both outer walls of the body are provided with slider structures, the slider structures being adapted to the guide rail so that the body can slide along the guide rail with the connecting component.

[0006] According to the above scheme, the main body includes a base plate and two side plates, the two side plates are spaced apart from each other, and the two sides of the base plate are respectively connected to the lower edges of the two side plates; a slot is formed between the base plate and the inner sidewalls of the two side plates, and a slider structure is provided on the outer sidewalls of the side plates.

[0007] According to the above scheme, the inner wall of the side plate is provided with a buckle strip, which is set along the upper edge of the side plate. The buckles on the two side plates are arranged opposite each other to form an opening.

[0008] According to the above scheme, a circular notch is provided at the gap between the side plate and the bottom plate.

[0009] According to the above scheme, a chamfer is provided between the upper end face and the inner side wall of the buckle strip.

[0011] According to the above scheme, the upper end of the vertical rib is provided with a clearance bevel.

[0012] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure. The main body can be directly fitted onto the bent part of the connector through the opening and slot. The main body is centrally set on the guide rail through the slider structure, thereby straightening the bent part of the connector.

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-4 As shown, the present invention provides a straightening component for a connecting rod of a lifting push-pull wheel assembly, comprising a body 1, a slot 11 on the body 1, and an opening 12 on the upper surface of the body 1, the opening 12 communicating with the slot 11, so that the connecting component 2 can pass through the opening 12 and be inserted into the slot 11; both outer walls of the body 1 are provided with slider structures, the slider structures being adapted to the guide rail 21 so that the body 1 can slide along the guide rail 21 with the connecting component 2.

[0021] It is understood that the connector 2 is used to connect two pulley pairs in the track wheel assembly. The connector 2 connects the two pulley pairs in a straight line to form a connection and is installed in the groove on the guide rail 21. The connector 2 is constrained by the straightness in the assembly tolerance.

[0022] The preferred embodiment of this invention has an opening 12 and a slot 11, through which the connector 2 can be inserted and positioned within the slot 11. The body 1 corresponds to the curved portion (apex of curvature) of the connector 2. The body 1 and the front and rear pulley pairs form a three-point positioning system for the connector 2. When the pulley pairs and connector 2 are installed into the guide rail 21, the body 1 is embedded into the groove of the guide rail 21, thereby correcting the connector 2. It is understood that multiple bodies 1 can be provided on the connector 2 to better correct it and control its straightness. The body 1 can slide along the guide rail 21 via a slider structure, thus fixing itself to the connector 2 and moving with it. This ensures the stability and smoothness of the pulley pair during operation, avoiding problems such as abnormal noise.

[0023] The main body 1 includes a base plate 100 and two side plates 200, which are spaced apart from each other. The two sides of the base plate 100 are respectively connected to the lower edges of the two side plates 200. A slot 11 is formed between the base plate 100 and the inner walls of the two side plates 200, and a slider structure is provided on the outer walls of the side plates 200. The base plate 100 and the two side plates 200 form a U-shaped main body 1 structure. The base plate 100 and the two side plates 200 are integrally molded structures. Preferably, the main body 1 is made of plastic, as the surface of the plastic main body 1 has better smoothness, reducing the friction when the main body 1 slides within the guide rail 21. The slot 11, opening 12, and slider structure can be integrally molded onto the main body 1.

[0024] The inner wall of the side plate 200 is provided with a fastening strip 13, which is set along the upper edge of the side plate 200. The fastening strips 13 on the two side plates 200 are arranged opposite each other to form an opening 12. The body 1 has a certain elastic deformation. The width of the connector 2 is equal to or slightly smaller than the width of the slot 11, but the width of the connector 2 is greater than the distance between the openings 12 between the fastening strips 13.

[0025] Preferably, a circular notch 14 is provided at the seam between the side plate 200 and the base plate 100. The circular notch 14 reduces the thickness of the connection between the side plate 200 and the base plate 100, i.e., the seam is thinned to improve the deformation freedom between the side plate 200 and the base plate 100. The side plate 200 can be deflected relative to the base plate 100 at a certain angle, making the opening 12 larger, making it easier for the connector 2 to pass through and be inserted into the slot 11, facilitating the installation of the body 1 onto the connector 2.

[0026] Furthermore, a chamfer 130 is provided between the upper end face and the inner side wall of the buckle 13, and the chamfer 130 on the buckle 13 makes it easier for the connector 2 to be inserted into the opening 12 and the slot 11.

[0027] The slider structure includes longitudinal ribs 22 and vertical ribs 23, which are arranged in a cross shape on the outer side wall of the side plate 200. The longitudinal ribs 22 have guide bevels 220 at both their front and rear ends. The longitudinal ribs 22 and 23 protrude from the outer side wall of the side plate 200, allowing the sides of the body 1 to conform to the inner wall of the groove of the guide rail 21, thereby controlling the bending deformation of the connecting piece 2 at the location of the body 1. Simultaneously, the longitudinal ribs 22 and 23 reduce the friction between the body 1 and the guide rail 21, making the sliding of the pulley pair on the guide rail 21 smoother.

[0028] like Figure 4 As shown, the upper end of the vertical rib 23 is provided with a relief bevel 230. For the rail 21 of some regions, such as the national standard, American standard and European standard, the groove depth of the rail 21 is different. The relief bevel 230 makes the body 1 adaptable to the rail 21 with a smaller depth.

[0029] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
