Abstract
Description
Technical Field
[0001] This application relates to the technical field of vehicle guardrails, and in particular to a guardrail for passenger and cargo vehicles. Background Technology
[0002] Car guardrails can effectively limit the movement of goods during transportation, preventing them from falling off. They can also be used to tighten goods that are tied together with ropes before transport.
[0003] However, in practical applications, most existing vehicles typically use hemp ropes to secure goods during transportation. However, because hemp ropes are flexible and have a certain degree of elasticity, the goods will vibrate to varying degrees during transportation due to bumps. As a result, the surface of the goods is easily damaged by bumps and collisions, which is not conducive to the widespread use of this method.
[0004] Therefore, those skilled in the art have provided a guardrail for passenger and cargo vehicles to solve the problems mentioned in the background art. Utility Model Content
[0005] To address the issue raised in the background art that, due to the elasticity of hemp rope, a flexible fixing method, goods are subject to varying degrees of vibration during transportation, which can easily lead to surface damage such as bumps and knocks, hindering its widespread use, this application provides a guardrail for passenger and cargo vehicles.
[0006] The technical solution for a guardrail for a passenger-cargo vehicle provided in this application is as follows: it includes two side frames, each with multiple mounting plates fixedly connected to its bottom end. These mounting plates are welded to an external cargo box. A single pressure frame is slidably connected vertically to the outer sides of the two side frames. A single horizontal plate is fixedly connected to the top of the two side frames. Two spiral rods are rotatably connected to the bottom of the horizontal plate. The pressure frame is helically driven and sleeved with the two spiral rods. A double-axis worm gear is rotatably connected to the top of the horizontal plate. Two worm wheels are meshed with the outer sides of the double-axis worm gear, and each worm wheel is fixedly sleeved with one of the two spiral rods.
[0007] Preferably, a hexagonal transmission sleeve is fixedly fitted on the outer side of the dual-axis worm gear, and the hexagonal transmission sleeve is located in the center of the dual-axis worm gear.
[0008] Preferably, two hollow sleeve blocks are fixedly connected to the top side of the cross plate, the two hollow sleeve blocks are symmetrically distributed, and the dual-axis worm gear is rotatably connected to the inner wall of the two hollow sleeve blocks.
[0009] Preferably, the bottom side of the pressing frame is fixedly connected with a plurality of rubber pads arranged in a matrix.
[0010] To sum up, the present application has the following beneficial technical effects:
[0011] 1. By setting the pressing frame, the mounting plate is sequentially welded on the carrier of the external device for fixation. When the goods are transported, first, the two side frames cooperate with each other to limit and fix the stacked goods from the front and rear sides. Meanwhile, the double-shaft worm is twisted, the double-shaft worm drives the two worm gears to rotate synchronously, and the two worm gears drive the two spiral rods to rotate synchronously. At this time, the two spiral rods cooperate with each other to make the pressing frame move horizontally downward. When the pressing frame moves to the limit position, the stacked goods can be limited and fixed from the top side. In this way, the bumping damage of the goods during transportation due to bumping can be avoided, and the use of the device is beneficial.
[0012] 2. By setting the six-rib transmission sleeve, when the double-shaft worm is twisted, the six-rib transmission sleeve can facilitate the worker to operate with a tool, so that the labor can be saved. BRIEF DESCRIPTION OF DRAWINGS
