Description

Technical Field

[0001] The utility model relates to the technical field of gas compressors, and more specifically to a dust filter component of a gas compressor which is easy to disassemble. Background Art

[0002] A gas compressor is a power device whose main function is to convert mechanical energy into gas pressure energy. This device is often used to provide gas power for pneumatic tools. When in use, a gas compressor needs to absorb a large amount of air from the outside air, and then there is often a large amount of floating dust in the air. If these dusts are not filtered and directly enter the gas compressor, it is easy to cause damage to the gas compressor equipment.

[0003] The Chinese authorized utility model patent with announcement number CN217795106U discloses a dust filter device for a gas compressor, which manually slides two convex blocks in opposite directions, so that a push rod pushes an L-shaped slide bar to slide, and then the filter frame slides along a guide groove through the L-shaped slide bar to be installed between a front frame and a rear frame, and then the two convex blocks are released, and the L-shaped clamping block can be clamped into a clamping slot through a first spring and a second spring, so that the filter frame can be quickly installed. Conversely, the L-shaped clamping block is disengaged from the clamping slot, and the filter can be quickly disassembled. After research by the inventor of the present application, it is found that the above patent also has the disadvantage of being more complicated to operate and making the loading and unloading speed slower. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a dust filter assembly for a gas compressor that is easy to disassemble, which can ensure the stable assembly effect while greatly simplifying the difficulty of loading and unloading the filter frame and filter element when the filter element needs to be cleaned, thereby greatly shortening the time required for loading and unloading the filter frame and filter element.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A dust filter assembly for a gas compressor that is easy to disassemble, comprises a front frame, a rear frame and a filter frame, the filter frame being installed in a slot between the front frame and the rear frame, the front frame and the rear frame being respectively provided with a grille plate and a seal, the filter frame being provided with a filter element, the filter frame being movably connected to the front frame and the rear frame, a pair of transverse slide grooves being provided at one end close to each other, the filter frame being provided with an adjustment groove and a placement groove that are interconnected, a driving adjustment mechanism being provided in the placement groove, and a driven adjustment mechanism being provided in the transverse slide groove, so that the difficulty of loading and unloading the filter frame and the filter element when the filter element needs to be cleaned can be greatly simplified while ensuring the stable assembly effect, thereby greatly shortening the time required for loading and unloading the filter frame and the filter element.

[0009] Furthermore, the driving adjustment mechanism includes an active adjustment block, which is inserted in a transverse sliding groove and movably connected thereto, the active adjustment block is set as a rectangular block, the inner end of the active adjustment block is fixedly connected to a magnetic block 1, the front and rear ends of the active adjustment block are provided with assembly grooves, a slider is slidably connected in the assembly groove, and a micro-compression spring is fixedly connected between the slider and the inner bottom end of the assembly groove, and the filter frame is also provided with a pair of active card grooves connected to the placement groove, and one end of the slider outside the assembly groove abuts against the active card groove, and the driven adjustment mechanism includes a driven adjustment block, which is located in the transverse sliding groove and slidably connected thereto, and the inner end of the driven adjustment block is fixedly connected to a magnetic block 2, and the front and rear ends of the filter frame are provided with limit grooves corresponding to the position of the driven adjustment block. When the filter frame is assembled, the driven adjustment mechanism is in the initial state. The block is located in the guard plate, and the filter frame is inserted into the slot between the front frame and the rear frame. When the bottom of the filter frame slides into the bottom of the slot, in this state, the magnetic poles of the end of the magnetic block one and the pair of magnetic blocks two that are close to each other are opposite, and a magnetic attraction force is generated between the magnetic block one and the magnetic block two, prompting the magnetic block two to move to the side close to the limiting slot until the two are engaged. At this time, the placement slot is partially located in the front frame and the rear frame, and partially located in the filter frame. At this time, the filter frame will not be detached from the slot between the front frame and the rear frame. When disassembling the filter frame, take the active adjustment block out of the placement slot, rotate it horizontally 180° and put it back into the placement slot. In this state, the magnetic block two and the magnetic block one that are close to each other have the same magnetic poles, and a magnetic repulsion force is generated between the magnetic block one and the magnetic block two. The magnetic block two drives the driven adjustment block to detach from the limiting slot and move toward the inner bottom end of the horizontal slide slot until it is reset. At this time, the filter frame can be taken out.

[0010] Furthermore, the movable slot is a concave hemispherical slot, and the shape of the end of the slider close to the movable slot is adapted thereto. After the active adjustment block is placed in the placement slot, the slider cooperates with the movable slot to prevent the active adjustment block from detaching from the placement slot without external interference.

[0011] Furthermore, a pull ring is fixedly connected to the upper top of the active adjustment block, and a handle is fixedly connected to the inner end of the adjustment groove. The heights of the pull ring and the handle are both smaller than the groove body depth of the adjustment groove, and the outer ends of the pull ring and the handle are provided with a rubber layer matching their shapes. The pull ring allows personnel to easily remove the active adjustment block from the placement groove to reverse the magnetic pole direction of magnetic block one, and the handle allows personnel to easily remove the filter frame from the slots of the front frame and the rear frame. Since the heights of the pull ring and the handle are both smaller than the groove body depth of the adjustment groove, they will not affect the operation of the equipment after the filter frame is assembled.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) This solution can achieve the effect of ensuring stable assembly while greatly simplifying the difficulty of loading and unloading the filter frame and filter element when the filter element needs to be cleaned, and greatly shortens the time required for loading and unloading the filter frame and filter element.

[0015] (2) The driving adjustment mechanism includes an active adjustment block, which is inserted into the transverse slide groove and movably connected thereto. The active adjustment block is set as a rectangular block. The inner end of the active adjustment block is fixedly connected to a magnetic block 1. Both the front and rear ends of the active adjustment block are provided with assembly grooves. A slider is slidably connected in the assembly groove. A micro-compression spring is fixedly connected between the slider and the inner bottom end of the assembly groove. The filter frame is also provided with a pair of movable card grooves connected to the placement groove. One end of the slider located outside the assembly groove abuts against the movable card groove. The driven adjustment mechanism includes a driven adjustment block. The driven adjustment block is located in the transverse slide groove and slidably connected thereto. The inner end of the driven adjustment block is fixedly connected to a magnetic block 2. Both the front and rear ends of the filter frame are provided with limit grooves corresponding to the position of the driven adjustment block. When the filter frame is assembled, the driven adjustment block is located in the guard plate in the initial state. The filter frame is moved from the front frame to the back frame. The filter frame is inserted into the slot between the front frame and the rear frame. When the bottom of the filter frame slides into the bottom of the slot, in this state, the magnetic poles of the end of the magnetic block 1 and the pair of magnetic blocks 2 that are close to each other are opposite, and a magnetic attraction is generated between the magnetic block 1 and the magnetic block 2, prompting the magnetic block 2 to move to the side close to the limiting slot until the two are engaged. At this time, the placement slot is partially located in the front frame and the rear frame, and partially located in the filter frame. At this time, the filter frame will not be separated from the slot between the front frame and the rear frame. When disassembling the filter frame, take the active adjustment block out of the placement slot, rotate it horizontally 180° and put it into the placement slot again. In this state, the magnetic poles of the end of the magnetic block 2 and the magnetic block 1 that are close to each other are the same, and a magnetic repulsion is generated between the magnetic block 1 and the magnetic block 2. The magnetic block 2 drives the driven adjustment block to separate from the limiting slot and move toward the inner bottom end of the horizontal slide slot until it is reset. At this time, the filter frame can be taken out.

[0016] (3) The movable slot is a concave hemispherical slot, and the shape of the end of the slider close to the movable slot is adapted thereto. After the active adjustment block is placed in the placement slot, the slider cooperates with the movable slot to prevent the active adjustment block from falling out of the placement slot without external interference.

[0017] (4) A pull ring is fixedly connected to the top of the active adjustment block, and a handle is fixedly connected to the inner end of the adjustment groove. The height of the pull ring and the handle are both less than the depth of the adjustment groove, and the outer ends of the pull ring and the handle are provided with a rubber layer matching the shape thereof. The pull ring is convenient for personnel to take out the active adjustment block from the placement groove to turn the magnetic pole direction of the magnetic block one, and the handle is convenient for taking out the filter frame from the slots of the front frame and the rear frame. Since the height of the pull ring and the handle are both less than the depth of the adjustment groove, they will not affect the operation of the equipment after the filter frame is assembled.
