Abstract
Description
Technical Field
[0001] This utility model relates to the field of air spring technology, and in particular to a cab air spring that is easy to install. Background Technology
[0002] An air spring is an industrial component that can provide support, cushioning, braking, height adjustment, and angle adjustment. It is a spring made by utilizing the compressibility of air in a closed container. In automobile cabs, air springs are used to reduce shock and improve comfort.
[0003] A search revealed that Chinese patent application number CN202122499469.2 discloses an easy-to-install car cab air spring. Through the cooperation of a top cover, mounting base, positioning groove, positioning block, through groove, limiting groove, sliding rod, movable plate, limiting block, connecting plate, first bolt, bottom cover, base, pull block, locking block, locking groove, and second bolt, the air spring can be easily disassembled and installed. The disassembly process is simple and convenient, greatly improving work efficiency. At the same time, it ensures the stability of the air spring after installation, preventing loosening at the connection points, improving practicality, and bringing great convenience to the user.
[0004] The above-mentioned technical solution has the following drawbacks. Although such a cab air spring structure can be basically positioned by the clips and slots, and then stabilized by bolts, in actual use, the air spring still needs to be fixed with bolts. However, the cab space is limited, and it is quite laborious to remove and install the fixing bolts when disassembling and assembling the air spring. To further facilitate installation, replacement, and maintenance, a cab air spring that is easy to install is proposed. It is equipped with two mounting brackets, one above the other. The mounting brackets are connected to the brackets or plates in the cab by screws or bolts. When disassembling and assembling the air spring body, it is not necessary to remove the mounting brackets. The mounting brackets are equipped with a positioning structure, which can be used to connect with the air spring. This allows the air spring to be installed in the cab without bolts, making the installation and disassembly process more convenient.
[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0007] This utility model provides a cab air spring that is easy to install, solving the problems mentioned in the background. It is equipped with a mounting bracket that connects to the cab via screws or bolts. When installing or removing the air spring, it is not necessary to disassemble the mounting bracket in the cab. The mounting bracket is equipped with a positioning structure, which can be used to connect with the air spring. This allows the air spring to be installed in the cab without bolts, making the installation and disassembly process more convenient.
[0008] The present invention provides the following solution to the above-mentioned technical problems: A cab air spring that is easy to install includes a mounting bracket, a cab air spring body, a limiting component, and a positioning screw. The cab air spring body is provided with a top plate and a bottom plate. Two mounting brackets are provided corresponding to the top plate and the bottom plate. Positioning components are fixedly installed on both the top plate and the bottom plate. An equipment slot is provided on the inner wall of the mounting bracket. A double-acting screw is rotatably connected to the inner wall of the equipment slot. A screw nut is threadedly connected to the outer wall of the double-acting screw. Two screw nuts are provided. Load-bearing sliders are fixed on both sides of the two screw nuts. A load-bearing rod is fixedly installed on the inner wall of the equipment slot. The load-bearing slider is fixedly connected to the limiting component. A nut is fixedly connected to the double-acting screw. The positioning screw passes through the nut for positioning.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, a waist ring is provided in the middle of the main body of the cab air spring, and a buffer block is fixedly installed on the inner wall of the main body of the cab air spring. The waist ring can limit the main body of the cab air spring from the side, and the buffer block can limit and protect the main body of the cab air spring when it is under great pressure, thus achieving an explosion-proof effect.
[0011] Furthermore, the load-bearing slider has a sliding hole corresponding to the load-bearing rod, and the inner wall of the sliding hole is slidably connected to the load-bearing rod, so that the load-bearing rod can limit the movement of the load-bearing slider and bear the load.
[0012] Furthermore, the nut has a positioning hole corresponding to the positioning screw, and the positioning screw can pass through the nut for positioning.
[0013] Furthermore, the mounting bracket has bolt grooves corresponding to the positioning screws, and the positioning screws can be threadedly connected to the mounting bracket.
[0014] Furthermore, the mounting bracket has a positioning groove corresponding to the top plate or bottom plate, and the top plate and bottom plate can be inserted into the mounting bracket for stable placement.
[0015] Furthermore, the mounting bracket has an inlet hole for the corresponding positioning component, and the positioning component can be inserted into the mounting bracket through the inlet hole for positioning.
[0016] Furthermore, mounting brackets are fixedly installed on both sides of the mounting bracket, and the mounting brackets have slotted holes through which bolts can pass to connect the mounting brackets to the inner wall of the cab.
[0017] This utility model provides a cab air spring that is easy to install, and has the following advantages:
[0018] 1. By passing bolts through the mounting brackets, the two mounting brackets can be connected to the cab support or plate according to the placement position of the cab air spring body. The cab air spring body is compressed and placed into the gap between the two mounting brackets to pre-position it. Rotating the screw cap will position and install the cab air spring body in the gap between the two mounting brackets. The overall installation steps are simple and easy to operate.
[0019] 2. The double-acting screw can be rotated in the equipment slot by turning the screw cap. When the double-acting screw rotates, the screw nut can drive the load-bearing slider to slide on the outer wall of the load-bearing rods on both sides, so that the limiting part can slide in the equipment slot until the positioning part is positioned, so that the positioning parts of the top plate and the bottom plate can be positioned in the mounting bracket. The positioning screw is threaded through the positioning hole of the screw cap and connected to the mounting bracket. The positioning screw can squeeze and position the screw cap to prevent it from rotating, thereby preventing the positioning part from falling out of the mounting bracket, so that the main body of the air spring in the cab can be stably installed in the gap between the mounting brackets on both sides.
[0020] 3. When it is necessary to disassemble, replace or repair the cab air spring body, simply unscrew the positioning screw and turn the cap in the opposite direction to release the positioning, so that the cab air spring body can be taken out from the gap of the mounting brackets on both sides for maintenance or replacement.
