Description

Technical Field

[0001] This application relates to components for special-purpose vehicles, and more particularly to a connector suitable for use in the superstructure of special-purpose vehicles. Background Technology

[0002] Special purpose vehicles typically have their superstructures installed on existing vehicle chassis. Different superstructures are installed depending on the specific needs. The superstructures are generally fixedly mounted on the sub-beams, which are then connected to the vehicle chassis using U-bolts.

[0003] The U-bolt fixing connection has the following disadvantages: 1. Poor stability, it can only limit the vehicle to the left and right, and its fixing effect is not good when the sub-beam moves towards the front or rear of the vehicle; 2. Inconvenient maintenance, when the U-bolt needs to be repaired or replaced, it is necessary to enter the bottom of the vehicle to operate when removing the U-bolt due to the installation of the upper structure. Summary of the Invention

[0004] The purpose of this utility model is to avoid the shortcomings of the prior art and provide a connector suitable for special vehicle mounting.

[0005] To solve the above problems, the technical solution of this utility model is: a connector suitable for the upper body of a special vehicle, which includes a chassis and an upper sub-beam. A lower connecting frame is fixedly connected to the chassis by bolts, and an upper connecting frame is fixedly connected to the upper sub-beam by bolts. The upper connecting frame and the lower connecting frame are fixedly connected by bolts.

[0006] The lower connecting frame includes a fixing plate, a connecting plate perpendicular to the top of the fixing plate, and side plates on both sides of the fixing plate and the connecting plate.

[0007] The upper connecting frame includes a second fixing plate, and a second connecting plate perpendicular to it is provided at the bottom end of the second fixing plate. Side plates are provided on both sides of the second fixing plate and the second connecting plate.

[0008] The connecting plate one and the connecting plate two are fixedly connected by bolts, and the inner side of the side plate one is in contact with the outer side of the side plate two.

[0009] The beneficial effects of this utility model are: 1. Good stability. The vertical direction is achieved by adjusting the bolt tension, the front and back direction is achieved by the tangential tension of the bolt and the blocking force of the side plate of the lower connecting frame, and the left and right direction is achieved by the opposing tension on both sides and the locking action of the side plate of the connecting frame.

[0010] Easy to install, not limited by space, and can be pre-positioned. The sub-beams and chassis can be pre-installed separately and then directly assembled, which can achieve quick disassembly and reduce maintenance complexity.

[0011] It is easy to maintain, with the connectors installed on both sides without obstruction, making it easy to disassemble or repair. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] exist Figures 1 to 4 In the present invention, a connecting component suitable for the upper body of a special vehicle is provided, comprising a chassis 1 and an upper sub-beam 2, wherein a lower connecting frame 4 is fixedly connected to the chassis 1 by bolts, and an upper connecting frame 3 is fixedly connected to the upper sub-beam 2 by bolts, and the upper connecting frame 3 and the lower connecting frame 4 are fixedly connected by bolts.

[0019] The lower connecting frame 4 includes a fixing plate 43, a connecting plate 41 perpendicular to the top of the fixing plate 43, and side plates 42 on both sides of the fixing plate 43 and the connecting plate 41.

[0020] The upper connecting frame 3 includes a second fixing plate 31, and a second connecting plate 33 perpendicular to the bottom of the second fixing plate 31. Side plates 32 are respectively provided on both sides of the second fixing plate 31 and the second connecting plate 33.

[0021] The connecting plate 41 and the connecting plate 33 are fixedly connected by bolts, and the inner side of the side plate 42 is in contact with the outer side of the side plate 32.

[0022] During installation, the upper connecting frame 3 fixes the fixing plate 2 31 to the upper sub-beam 2 with bolts, and the lower connecting frame 4 fixes the fixing plate 43 to the chassis 1 with bolts. The connecting plate 41 and the connecting plate 33 are fixedly connected with bolts, thus fixing the upper connecting frame 3 and the lower connecting frame 4 together. At this time, the inner side of the side plate 42 contacts the outer side of the side plate 32, which can limit the movement of the upper connecting frame 3 in the direction of the front or rear of the vehicle, thereby limiting the movement of the upper sub-beam 2. In this structure, the vertical direction is secured by adjusting the bolt tension, the front and rear direction is secured by the tangential tension of the bolts and the blocking force of the side plate 42 of the lower connecting frame 4, and the left and right direction is secured by the opposing tension on both sides and the locking action of the side plate 42 of the lower connecting frame 4.

[0023] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. However, the above description is only a preferred embodiment of this utility model. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched by those skilled in the art to form various equivalent solutions without departing from or changing the design concept and technical effects of this utility model.
