Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a dust collector that is easy to move. Background Technology

[0002] A dust collector is a device used to capture and remove solid particulate matter, such as dust, smoke, and particulate matter, from the air. It primarily works through principles such as filtration, inertial separation, and electrostatic sedimentation to separate solid particles from the air, thereby purifying the air and reducing dust concentration. Many industries and workplaces, such as manufacturing, quarrying, welding, and woodworking, generate large amounts of dust. This dust, transported through the air, can cause environmental pollution and potentially harm workers' health. Dust collectors were developed to address dust pollution problems, improve air quality, and enhance the working environment.

[0003] A search revealed patent application number (202122200710.7), which discloses "a baghouse dust collector that is easy to move and adjust," comprising a support platform, a dust collection box fixedly connected to the middle of the support platform, a slag discharge hopper welded to the bottom of the dust collection box, a slag discharge valve connected to the slag discharge hopper via a flange, and an air inlet pipe fixedly connected to one side wall of the dust collection box. This utility model uses a clamping ring and clamping groove to clamp the filter bag opening to the bottom of the top sealing box, completely sealing the outer perimeter of the filter bucket, improving filtration efficiency and quality. When disassembling the filter bag, simply pull the filter bag downwards to pull the clamping ring out of the clamping groove, improving filter bag replacement efficiency. When replacing the filter bag, the top sealing box can be moved upwards by the lifting push rod, exposing the filter bag to the outside. The sealing ring seals the joint between the top sealing box and the dust collection box, facilitating filter bag replacement operations, making it extremely convenient.

[0004] However, the above-mentioned device has the following problems: Most dust collectors on the market are equipped with casters at the bottom, which facilitates movement. However, when moved by external forces, the dust collector is prone to collision damage during use. At the same time, the movement affects the dust collector's ability to filter impurities in the air, thereby reducing the practicality of the dust collector. Therefore, we have proposed a dust collector that is easy to move to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 The present invention provides an embodiment of a portable dust collector, comprising a dust collection box 1, a base 2 fixedly installed at the lower end of the dust collection box 1, four pairs of support legs 3 fixedly connected to the bottom of the base 2, and a traveling wheel 4 rotatably connected inside the support legs 3. A limit assembly 5 is provided at the bottom of the base 2, and an adjustment assembly 6 is provided inside the base 2. The limit assembly 5 includes a positioning block 501, a first adjusting rod 502, a limit block 503, and a ratchet 504. A positioning block 501 is provided at the bottom of the dust collection box 1, and two sets of first adjusting rods 502 are provided on the left and right sides of the positioning block 501. A limit block 503 is provided at the end of the first adjusting rod 502, and a ratchet 504 is fixedly installed at the center of the traveling wheel 4.

[0025] This device, through the setting of the limiting component 5 and the adjusting component 6, solves the problem that the dust collector is prone to movement under the action of external force, which leads to collision damage during use, and at the same time affects the dust collector's ability to filter impurities in the air when it is moving.

[0026] Furthermore, the adjusting assembly 6 includes a screw 601, a movable block 602, an adjusting ring 603, a second adjusting rod 604, and a fixed block 605. The screw 601 is rotatably connected inside the base 2. Two sets of movable blocks 602 are threadedly connected to the surface of the screw 601. The adjusting ring 603 is fixedly connected to the right end of the screw 601. The second adjusting rod 604 is rotatably connected to the lower ends of the two sets of movable blocks 602. The fixed block 605 is fixedly connected to the surface of the first adjusting rod 602. The other end of the second adjusting rod 604 is rotatably connected to the fixed block 605. Figure 2As shown, this structure is used to rotate the screw 601 by rotating the adjusting ring 603, causing the two sets of movable blocks 602 on the surface of the screw 601 to move towards the center. Under the action of the second adjusting rod 604 being rotatably connected to the first adjusting rod 502 and the movable blocks 602 through the fixing block 605, the second adjusting rod 604 is driven to rotate the first adjusting rod 502 inward, adjusting the angle of the first adjusting rod 502, and limiting the travel wheel 4 or vice versa to release the limit.

[0027] Furthermore, the positioning block 501 is located at the center of the base 2, and its top end is fixedly connected to the bottom of the base 2. A bearing is installed inside the positioning block 501, and the screw 601 is rotatably connected to the positioning block 501 via the bearing. Two sets of first adjusting rods 502 are symmetrically distributed on the left and right sides of the positioning block 501 and are rotatably connected to it. The end of the limiting block 503 is provided with teeth that mesh with the ratchet 504. Figure 2 As shown, this structure is used to rotate the first adjusting rod 502 to insert the limiting block 503 at the end of the first adjusting rod 502 into the gap of the ratchet 504. Under the action of the teeth at the limiting block 503 and the ratchet 504 meshing with each other, the ratchet 504 is limited.

[0028] Furthermore, a disassembly assembly 7 is provided between the first adjusting rod 502 and the limiting block 503. The disassembly assembly 7 includes a slot 71, a connecting frame 72, a connecting block 73, a positioning hole 74, and a pin 75. A slot 71 is provided at the lower end of the first adjusting rod 502, and a connecting block 73 is inserted into the slot 71. The connecting frame 72 is fixedly connected to the outer end of the connecting block 73. Positioning holes 74 are provided on the upper and lower sides of the slot 71, and pins 75 are inserted into the positioning holes 74. The limiting block 503 is set in the connecting frame 72, and the ratchet wheels 504 on the left and right sides are symmetrically distributed so that the teeth of the ratchet wheels 504 face opposite directions. Figure 3 As shown, this structure is used to remove the corresponding pin 75 by using the required method, thereby releasing the fixing of the connecting block 73, and pulling the connecting bracket 72 to disengage the connecting block 73 from the inside of the slot 71 and remove it, as shown. Figure 2 As shown, by removing the limiting block 503 at the corresponding position, the dust collector 1 can only move forward or backward, which can effectively limit the movement trajectory of the dust collector 1.

[0029] Furthermore, a fixing rod 8 is inserted inside the limiting block 503. Both ends of the fixing rod 8 are fixedly connected to the inner wall of the connecting frame 72. The limiting block 503 is rotatably connected to the connecting frame 72 via the fixing rod 8. Torsion springs 9 are movably sleeved on the outer surfaces of both ends of the fixing rod 8. One end of the torsion spring 9 is connected to the inner wall of the connecting frame 72, and the other end of the torsion spring 9 is connected to the inner wall of the limiting block 503. Figure 4As shown, this structure is used to adjust the angle of the first adjusting rod 502 by setting the fixed rod 8 and the torsion spring 9, so that the limiting block 503 contacts the ratchet 504. Under the rotation of the limiting block 503, the limiting block 503 is automatically adjusted, and under the elastic action of the torsion spring 9, the teeth at the limiting block 503 are engaged with the gap of the ratchet 504. At the same time, when restricting the movement direction of the dust collector 1, the dust collector 1 moves in the specified direction, so that the traveling wheel 4 rotates, and the ratchet 504 corresponding to the traveling wheel 4 pushes the limiting block 503 to rotate. When moving in the opposite direction, under the mutual meshing of the limiting block 503 and the ratchet 504, the traveling wheel 4 cannot move in the opposite direction.

[0030] Furthermore, a guide block 10 is fixedly connected to the bottom of the connecting frame 72, and the surface of the guide block 10 is provided with a cut that matches the limiting block 503. For example... Figure 4 As shown, this structure is used to limit the rotation angle of the limit block 503 by setting the guide block 10, so as to ensure the stability of the limit block 503.

[0031] Furthermore, the outer surface of the adjusting ring 603 is provided with a rubber pad, and the surface of the rubber pad is provided with a wavy anti-slip texture with a depth of two millimeters. Figure 2 As shown, this structure utilizes the cushioning and anti-slip properties of rubber. Its anti-slip texture enhances its anti-slip effect, preventing slippage from the hand. Furthermore, the two-millimeter depth ensures that the anti-slip texture retains its anti-slip effect even after a certain degree of wear.

[0032] Working principle: When using, such as Figure 1 and Figure 2 As shown, the dust collector 1 is moved to the designated position using the wheels 4. Once at the designated position, the adjusting ring 603 is rotated, causing the screw 601 to rotate. This causes the two sets of movable blocks 602 on the surface of the screw 601 to move towards the center. Under the action of the second adjusting rod 604 being rotatably connected to the first adjusting rod 502 and the movable blocks 602 via the fixed block 605, the second adjusting rod 604 is driven to rotate the first adjusting rod 502 inward, adjusting the angle of the first adjusting rod 502. Figure 4 As shown, the limiting block 503 contacts the ratchet 504. Under the rotation of the limiting block 503, it automatically adjusts, and under the elastic action of the torsion spring 9, the teeth of the limiting block 503 engage with the gap of the ratchet 504. The meshing of the teeth of the limiting block 503 and the ratchet 504 limits the ratchet 504, fixing the dust collector box 1 in the designated position. The reverse operation releases the limiting action. Figure 3 and Figure 4As shown, according to usage requirements, when it is necessary to restrict the movement direction of the dust collector 1, the dust collector 1 moves in the specified direction. The corresponding pin 75 is removed, the fixing of the connecting block 73 is released, and the connecting frame 72 is pulled to disengage the connecting block 73 from the slot 71 and remove it. By removing the corresponding limiting block 503, the dust collector 1 can only move forward or backward, effectively restricting the movement trajectory of the dust collector 1. This causes the traveling wheel 4 to rotate, and the corresponding ratchet 504 at the traveling wheel 4 pushes the limiting block 503 to rotate. When moving in the opposite direction, the interaction between the limiting block 503 and the ratchet 504 prevents the traveling wheel 4 from moving in the opposite direction. The above is the complete working principle of this utility model.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
