Technical Field
[0001] The utility model relates to the technical field of engine filters, in particular to an engine filter which is convenient to install. Background Art
[0002] An engine filter is a device used to filter impurities and wastes generated during the operation of an engine. According to different filtration objects, engine filters can be divided into three types: air filters, oil filters, and fuel filters. An air filter is a filter mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation rooms, and various precision operation rooms. It can filter out impurities such as dust and sand grains in the air, ensure sufficient and clean air enters the cylinder, and thus protect the normal operation of the engine.
[0003] During the use of the existing air filter, it needs to be disassembled regularly for maintenance. The common installation method of the air filter is bolt connection. The air filter is fixed on the housing base through bolts. Since the number of thread turns of the connecting bolts is too many, and a torque wrench is required to disassemble the bolts during installation and disassembly, it is rather troublesome to install and disassemble the air filter. Furthermore, it is not conducive to the user's later maintenance of the air filter, and other internal structures of the air filter may be damaged due to improper operation, affecting the working efficiency of the air filter and the operation of the engine.
[0004] Therefore, it is necessary to provide a new engine filter that is convenient to install to solve the above technical problems. Summary of the Utility Model
[0005] To solve the above technical problems, the utility model provides an engine filter that is convenient to install.
[0006] The engine filter that is convenient to install provided by the utility model includes a bottom plate and a filter body. The filter body is connected to the inner wall of a groove opened at the top of the bottom plate through a fixing plate. A fixing device is fixedly connected to the inner walls of limiting grooves opened on both sides of the filter body at the top of the bottom plate.
[0007] The fixing device includes a fixing block, a fixing baffle, a sliding block and a first spring. The fixing block is fixedly connected to the inner wall of the limiting groove formed at the top of the bottom plate. The fixing baffle is fixedly connected to the inner wall of the fixing block, and a limiting component is movably connected to the inner wall of the through hole formed in the fixing baffle. The sliding block is movably connected to the inner wall of the through hole formed at the top of the fixing block, and one end of the sliding block located inside the fixing block is fixedly connected to the side wall of the limiting component. One end of the first spring is fixedly connected to the top wall of the fixing block, and the end of the first spring away from the fixing block is fixedly connected to a movable column. The movable column is movably connected to the inner wall of the through hole formed in the sliding block, and a clamping plate is movably connected to the inner wall of the groove formed in the side wall of the movable column. One end of the clamping plate away from the movable column is fixedly connected to a fixing column. The top of the fixing column is fixedly connected to a pressing plate, and the bottom wall of the fixing column is fixedly connected to a second spring. The end of the second spring away from the fixing column is fixedly connected to the top of the fixing block.
[0008] Preferably, the limiting component includes a connecting rod and an elastic member. The connecting rod is movably connected to the inner wall of the through hole formed in the baffle. The connecting rod is fixedly connected to a limiting plate. One end of the limiting plate away from the connecting rod is movably connected to the inner wall of the fixing groove formed in the side wall of the fixing plate. And one end of the connecting rod away from the limiting plate is fixedly connected to a movable plate. The movable plate is fixedly connected to one end of the sliding block located inside the fixing block. The elastic member is sleeved on the connecting rod. One end of the elastic member is fixedly connected to the side wall of the fixing baffle, and the end of the elastic member away from the fixing baffle is fixedly connected to the side wall of the limiting plate.
[0009] Preferably, the elastic member is a third spring. The third spring is sleeved on the connecting rod. One end of the third spring is fixedly connected to the side wall of the fixing baffle, and the end of the third spring away from the fixing baffle is fixedly connected to the side wall of the limiting plate.
[0010] Preferably, one end of the sliding block located inside the fixing block is fixedly connected to the side wall of the movable plate.
[0011] Preferably, one side of the limiting plate adjacent to the fixing plate is inclined.
[0012] Preferably, a plurality of fixing holes are formed in the top of the bottom plate.
[0013] Compared with the related art, an engine filter provided by the utility model, which is convenient for installation, has the following beneficial effects:
[0014] Through the provided fixing device, when the air filter needs to be disassembled, first press the pressing plate. The pressing plate will drive the movable column to move downward through the engaging plate provided on the side wall of the fixing column. When the movable column loses the limit on the sliding block, the sliding block can be moved. The sliding block drives the movable plate to move. The movable plate drives the limiting plate to slide through the third spring and the connecting rod, so that the limiting plate disengages from the inner wall of the fixing groove opened on the side wall of the fixing plate. At this time, the filter element body can be disassembled. This device solves the problem that both the installation and disassembly of the air filter are relatively troublesome, avoids the problem that it is not conducive to the later maintenance of the air filter by the user, and avoids the damage of other structures inside the air filter caused by improper operation, reducing the impact on the working efficiency of the air filter and the operation of the engine.
