Description

Technical Field

[0001] This utility model belongs to the field of rail transit technology, specifically relating to a connection structure between an installation base and a cabinet. Background Technology

[0002] Currently, when cabinets need to be installed on rail transit vehicles, a base is typically installed on the vehicle. The base has mounting holes, and the cabinet's mounting base itself has horizontal or vertical slots, the positions of which correspond to the mounting holes on the base. During installation, fasteners, typically bolts, pass through the slots on the mounting base and connect to the mounting holes on the base, thus securing the cabinet to the rail transit vehicle. Additionally, the slots on the mounting base allow for adjustment of the cabinet's position relative to the vehicle. However, this installation method has significant limitations. The slots are generally horizontal or vertical, limiting the range of adjustment for the cabinet's position relative to the vehicle. It cannot be adjusted within a 360° range, thus failing to compensate for installation problems caused by base positional errors and making it difficult to meet the needs of fast-paced production. Utility Model Content

[0003] In view of the existing technical problems, this utility model aims to provide a connection structure between the mounting base and the cabinet, which can solve the technical problem of limited adjustment range of the cabinet and vehicle installation position in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A mounting base includes a mounting base body, which can be fixed to a base by fasteners. Its structural features include: a first fixing member and a circular movable member; the circular movable member has an oblong hole, the width of which matches the diameter of the fastener; the first fixing member is fixedly connected to the mounting base body, and a receiving cavity for accommodating the circular movable member is provided between the first fixing member and the mounting base body, allowing the circular movable member to rotate within the receiving cavity; the mounting base body has a first through hole, and the first fixing member has a second through hole corresponding to the first through hole, the size of the second through hole being greater than or equal to the size of the first through hole; when the mounting base body is connected to the base, rotating the circular movable member allows the axial centerline of the mounting hole on the base to simultaneously pass through the first through hole, the oblong hole, and the second through hole.

[0006] By setting a first fixing member on the mounting base body, the circular movable member is fixed to the mounting base body. Simultaneously, the circular movable member can rotate within a 360° range on the surface of the mounting base body. In use, the mounting base body is placed on the base, and the circular movable member is rotated to connect the mounting hole on the base with the first through hole, the oblong hole, and the second through hole. The lower end of a fastener passes through the second through hole, the oblong hole, and the first through hole in sequence and connects to the base. The upper end of the fastener abuts against the circular movable member, thereby achieving a fixed connection between the mounting base and the base. Because the circular movable member of this invention can rotate within a 360° range within the receiving cavity, even if there is an error in the position of the mounting hole on the base, rotating the circular movable member can connect the oblong hole with the mounting hole on the base, thus achieving a fixed connection between the mounting base and the base and improving the assembly efficiency of the component.

[0007] Preferably, both the first through hole and the second through hole are circular holes, and the axial center lines of the first through hole and the second through hole coincide.

[0008] Preferably, the length of the oblong hole is less than or equal to the diameter of the first through hole. Depending on the actual installation requirements of the mounting base, the length of the oblong hole generally needs to be equal to the diameter of the fastener plus the required tolerance dimension. The diameter of the first through hole is slightly larger than or equal to the length of the oblong hole, providing a connection between the oblong hole and the mounting hole of the base.

[0009] Preferably, the axial center lines of the waist-shaped hole, the first through hole, and the second through hole coincide.

[0010] Specifically, the diameters of both the first and second through holes are smaller than the diameter of the circular movable component. The diameter of the circular movable component is generally slightly larger than the diameters of the first and second through holes, so that the circular movable component can be fixed within the receiving cavity.

[0011] Specifically, the receiving cavity is a cylindrical cavity, and the diameter of the cylindrical cavity is larger than the diameter of the circular movable part.

[0012] Based on the same inventive concept, this utility model also provides a cabinet connection structure, including a base and a cabinet. The cabinet is provided with the mounting base as described above. The first fixing member and the base are respectively arranged on opposite sides of the mounting base body. The mounting base body and the base are fixed together by a plurality of fasteners, which are connected to the base by passing through a second through hole, a waist-shaped hole and a first through hole in sequence.

[0013] The cabinet connection structure of this utility model allows for installation even if there are manufacturing errors in the dimensions of the base provided for cabinet mounting. By rotating the circular movable part, a suitable position can be found where the center of the oblong hole coincides with the center of the mounting hole on the base, thus enabling cabinet installation. This cabinet connection structure also allows for adjustment of the gap between the cabinet and surrounding cabinets or the surrounding environment by adjusting the position of the circular movable part. This effectively solves the problem of excessive gaps or interference between equipment, demonstrating significant application value in practical use, improving overall vehicle assembly efficiency, and reducing unnecessary rework.

[0014] Specifically, the fastener is a bolt, and the fastener is detachably and fixedly connected to the base by threads.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The mounting base of this utility model allows the circular movable part to rotate within a 360° range within the accommodating cavity. Even if there is an error in the position of the mounting hole on the base, rotating the circular movable part can connect the waist-shaped hole with the mounting hole of the base, thereby achieving a fixed connection between the mounting base and the base and improving the assembly efficiency of the component.

[0017] 2. The cabinet connection structure of this utility model can achieve cabinet installation even if there is a manufacturing error in the size of the base provided for cabinet installation. By rotating the circular movable part, a suitable position can be found where the center of the waist-shaped hole coincides with the center of the mounting hole of the base, thereby realizing the installation of the cabinet.

[0018] 3. The cabinet connection structure of this utility model controls the gap between the cabinet and the surrounding cabinets or the surrounding environment by adjusting the position of the circular movable parts, thereby achieving the purpose of adjusting the gap. This effectively solves the problem of excessive gaps or interference between equipment, and has great application value in practical use. It can improve the assembly efficiency of the whole vehicle and reduce unnecessary rework. Attached Figure Description
