Abstract
Description
Technical Field
[0001] The utility model relates to a parallel side sliding door for special vehicles. Background Art
[0002] In the prior art, a parallel side sliding door is used for a special vehicle. The special vehicle includes a car chassis and a box body mounted on the car chassis. The parallel side sliding door is arranged below the box body. The parallel side sliding door includes a corresponding door frame and a door body. A rotating rod is hinged between the upper and lower side frames of the door frame and the upper and lower parts of the door body. A handle is provided on the outside of the door body. When the handle is held to open the door, the door body can be translated to one side outside the door frame. When the door is closed, the door body can be translated into the door frame.
[0003] The above-mentioned parallel side sliding doors for special vehicles in the prior art open in parallel to the sides, without blocking the upper box of the vehicle and without hindering the operation of the upper box. However, during long-term use, it is found that the door body sinks, which to some extent affects the normal opening and closing of the door body. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a parallel side sliding door for special vehicles, which is not prone to sinking even after long-term use and does not affect the normal opening and closing of the door body.
[0005] In order to solve the above technical problems, the utility model provides a parallel side sliding door for special vehicles, wherein the special vehicle includes a car chassis and a box body mounted on the car chassis, and the parallel side sliding door is arranged below the box body. The parallel side sliding door includes a corresponding door frame and a door body, and a rotating rod is hinged between the upper and lower side frames of the door frame and the upper and lower parts of the door body respectively. A handle is provided on the outside of the door body, and positioning blocks are fixed at intervals on the lower side frame, and each positioning block has an inclined surface formed on the side facing the door body.
[0006] The parallel side sliding door for special vehicles adopts the above structure. Since positioning blocks are fixed at intervals on the lower frame, and the positioning blocks have an inclined surface on the side facing the door body, when closing the door, the bottom of the door body is just supported and limited by the inclined surface, which can achieve closing limit and prevent the door body from sinking, and will not affect the normal opening and closing of the door body.
[0007] Furthermore, the positioning block is formed by cutting off the triangular prism on one side of the rectangular block facing the door body. The positioning block of the utility model is generally rectangular in shape as a whole and is easy to process.
[0008] Furthermore, pins are fixed to the upper and lower frames and the upper and lower parts of the door body, respectively, and bearings are installed on the pins. Correspondingly, the two ends of the rotating rod are fixed to the bearings of the corresponding pins. With the above technical features, the rotating rod can rotate with low resistance, making the door opening and closing more labor-saving.
[0009] Furthermore, the door also includes a gas strut, the rod end of which is hinged to the lower frame, and the cylindrical end of which is fixed to one end of a rotating rod adjacent to a bearing located on the lower frame. With these technical features, the gas strut reduces opening torque and, when closing, compresses the door toward the door frame by means of a force component, preventing the door from automatically opening during driving and causing a safety accident. The gas strut limits the door's maximum opening position. BRIEF DESCRIPTION OF THE DRAWINGS
