Description

Technical Field

[0001] This utility model relates to the field of dust bags, and in particular to a pull-out type sealing dust bag structure. Background Technology

[0002] A dust bag is a bag used to collect and store dust, trash, or other small particles. It is commonly found in vacuum cleaners, industrial equipment, cleaning tools, and other similar applications.

[0003] When using dust bags, an inlet is provided at the mounting plate on one side of the bag. The mounting plate connects the bag to other equipment. After the bag is removed, the sealing plate on one side of the mounting plate is moved to seal the inlet and prevent dust leakage. However, if the sealing plate is not properly positioned to stop the dust inlet, it can easily detach from the inlet under stress, affecting the dust bag's performance. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the sealing plate blocks the ash inlet, it does not limit the sealing plate's movement. As a result, the sealing plate is prone to detach from the ash inlet on one side of the bag body after being subjected to force, which affects the effectiveness of the dust bag.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pull-out type sealing dust bag structure, including a bag body, an installation plate on one side of the bag body, an ash inlet on the side of the bag body near the installation plate, a limiting device on one side of the installation plate, and a sealing plate on the installation plate with the aid of the limiting device, wherein the limiting device limits the sealing plate.

[0006] The effect achieved by the above components is as follows: When using the dust bag, an inlet is opened at the mounting plate on one side of the bag body. The mounting plate connects the bag body to other equipment. After the bag body is removed, the sealing plate on one side of the mounting plate is moved to seal the inlet and prevent dust from leaking out. At this time, a limiting device is used to limit the position of the sealing plate on the mounting plate.

[0007] Preferably, the limiting device includes a groove, a sliding block, a bolt, and a threaded groove on one side of the mounting plate. The sliding block moves in the groove on one side of the mounting plate, and one side of the sliding block is connected to the sealing plate. The bolt is inserted into one side of the sliding block and is adapted to the size of the threaded groove on one side of the mounting plate.

[0008] The aforementioned components achieve the following effects: When using the sealing plate, the sliding block moves within a groove on one side of the mounting plate, causing the sealing plate, which is fixed on one side, to reach the ash inlet on one side of the bag, thus sealing the ash inlet. Then, the bolt is rotated, causing it to rotate within the threaded groove on one side of the mounting plate for threaded connection, thus limiting and fixing the positions of the sliding block and the sealing plate. When the sealing plate is not in use, the sliding block moves the sealing plate away from the ash inlet on one side of the bag. Then, the bolt is rotated, causing one end of the bolt to abut against the inner wall of the groove on the mounting plate, thus limiting the position of the sealing plate. By using this limiting device, the position of the sealing plate on the mounting plate can be limited, preventing the sealing plate from being unlimited when sealing the ash inlet and then detaching from the ash inlet on one side of the bag under pressure. This improves the effectiveness of the sealing plate and, consequently, the effectiveness of the dust bag.

[0009] Preferably, a control block is provided on one side of the bolt, and the control block increases the dimension of one side of the bolt.

[0010] The effect achieved by the above components is that by fixing the control block to the bolt, the size of one side of the bolt is increased, making it easier for the bolt to rotate.

[0011] Preferably, a groove is formed on one side of the control block, and the groove on one side of the control block is located at the center of the bolt.

[0012] The effect achieved by the above components is that by opening a groove on one side of the control block at the center of the bolt, the control block can be connected with external tools, making it easier to rotate the bolt.

[0013] Preferably, a rubber pad is provided on the side of the bolt near the mounting plate, and the rubber pad increases the friction on one side of the bolt.

[0014] The effect achieved by the above components is to increase the friction between the bolt and the inner wall of the groove on one side of the mounting plate by fixing the rubber pad on the side of the bolt, so that the bolt can better abut and fix with the groove on one side of the mounting plate.

[0015] Preferably, a plurality of anti-slip blocks are provided at equal intervals on one side of the sliding block, and the plurality of anti-slip blocks increase the friction on one side of the sliding block.

[0016] The effect achieved by the above components is that by fixing several anti-slip blocks equidistantly on one side of the sliding block, the friction on one side of the sliding block is increased, making the sliding block easier to move.

[0017] Preferably, the sliding block has arc strips on both sides, and the arc surface of the arc strips has a groove on the side close to the mounting plate.

[0018] The effect achieved by the above components is as follows: by fixing the arc strips on both sides of the sliding block, and with the arc surface of the arc strips close to the groove on the side of the mounting plate, the contact area between the sliding block and the mounting plate is reduced, thereby reducing the friction between the two, and making it easier for the sliding block to move.

[0019] Preferably, a round rod is provided inside the groove on one side of the mounting plate, the round rod passes through the sliding block and slides with the sliding block.

[0020] The effect achieved by the above components is as follows: the round rod is fixed to the sliding groove on one side of the mounting plate, and the round rod passes through the sliding block to slide and connect with the sliding block, thereby increasing the connection strength between the sliding block and the mounting plate and preventing the sliding block from separating from the sliding groove on one side of the mounting plate under force.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a limiting device, the position of the sealing plate on the mounting plate can be limited, preventing the sealing plate from being unlimited when blocking the ash inlet and then detaching from the ash inlet on one side of the bag after being subjected to force. This improves the effectiveness of the sealing plate and, consequently, the effectiveness of the dust bag. Attached Figure Description

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figures 1 to 4 The illustrated dust bag structure includes a bag body 1, an mounting plate 2 on one side of the bag body 1, a dust inlet 3 on the side of the bag body 1 near the mounting plate 2, a limiting device 5 on one side of the mounting plate 2, and a sealing plate 4 mounted on the mounting plate 2 via the limiting device 5. The limiting device 5 limits the position of the sealing plate 4. When using the dust bag, the dust inlet 3 is opened at the mounting plate 2 on one side of the bag body 1. The mounting plate 2 connects the bag body 1 to other equipment. After the bag body 1 is removed, the sealing plate 4 on one side of the mounting plate 2 is moved to seal the dust inlet 3, preventing dust leakage. The limiting device 5 then limits the position of the sealing plate 4 on the mounting plate 2.

[0032] Figures 1 to 4 The limiting device 5 shown includes a groove 51, a sliding block 52, a bolt 53, and a threaded groove 54 on one side of the mounting plate 2. The sliding block 52 moves in the groove 51 on one side of the mounting plate 2. One side of the sliding block 52 is connected to the sealing plate 4. The bolt 53 is inserted into one side of the sliding block 52 and is adapted to the size of the threaded groove 54 on one side of the mounting plate 2. When the sealing plate 4 is used, the sliding block 52 is moved so that it moves in the groove 51 on one side of the mounting plate 2. Then, the sliding block 52 drives the sealing plate 4, which is fixed on one side, to the ash inlet 3 on one side of the bag body 1 to seal the ash inlet 3 of the bag body 1. Then, the bolt 53 is rotated so that the bolt 53 rotates inside the sliding block 52 and reaches the threaded groove 54 on one side of the mounting plate 2 for threaded connection. This completes the limiting and fixing of the position of the sliding block 52 and the sealing plate 4. When the sealing plate 4 is not used, the sliding block 52... Move the sealing plate 4 away from the ash inlet 3 on the side away from the bag body 1, and then rotate the bolt 53 so that one end of the bolt 53 abuts against the inner wall of the sliding groove 51 of the mounting plate 2 to complete the position limit of the sealing plate 4. By using the limiting device 5, the position of the sealing plate 4 on the mounting plate 2 can be limited, so as to avoid the situation where the sealing plate 4 does not limit the ash inlet 3 when it is blocking the ash inlet 3, and then the sealing plate 4 is separated from the ash inlet 3 on the side of the bag body 1 after being subjected to force, thereby improving the use effect of the sealing plate 4, and thus improving the use effect of the dust bag.

[0033] Figures 1 to 4A control block 55 is provided on one side of the bolt 53, which raises the dimension of one side of the bolt 53. The control block 55 is fixed to the bolt 53, and the raised dimension of one side of the bolt 53 makes it easier to rotate. A groove 56 is formed on one side of the control block 55, located at the center of the bolt 53. This groove 56 allows the control block 55 to engage with external tools, further facilitating the rotation of the bolt 53.

[0034] Figures 1 to 4 A rubber pad 57 is provided on the side of the bolt 53 near the mounting plate 2, which increases the friction on one side of the bolt 53. By fixing the rubber pad 57 to the side of the bolt 53 near the mounting plate 2, the friction between the bolt 53 and the inner wall of the groove 51 on one side of the mounting plate 2 is increased, allowing the bolt 53 to better abut and be fixed to the groove 51 on one side of the mounting plate 2. Several anti-slip blocks 58 are equidistantly provided on one side of the sliding block 52, which increases the friction on one side of the sliding block 52. By fixing the anti-slip blocks 58 equidistantly on one side of the sliding block 52, the friction on one side of the sliding block 52 is increased, making the sliding block 52 easier to move.

[0035] Figures 1 to 4 The sliding block 52 shown has arcuate strips 59 on both sides, with the arcuate surfaces of the arcuate strips 59 close to the groove 51 on the side of the mounting plate 2. By fixing the arcuate strips 59 to both sides of the sliding block 52, and with the arcuate surfaces of the arcuate strips 59 close to the groove 51 on the side of the mounting plate 2, the contact area between the sliding block 52 and the mounting plate 2 is reduced, thereby reducing the friction between them and making it easier for the sliding block 52 to move. A round rod 510 is provided inside the groove 51 on the side of the mounting plate 2. The round rod 510 passes through the sliding block 52 and slides with the sliding block 52. By fixing the round rod 510 to the groove 51 on the side of the mounting plate 2 and passing through the sliding block 52, a sliding connection is formed with the sliding block 52, thereby increasing the connection strength between the sliding block 52 and the mounting plate 2 and preventing the sliding block 52 from separating from the groove 51 on the side of the mounting plate 2 under force.

[0036] Working Principle: When using the dust bag, an inlet 3 is opened at the mounting plate 2 on one side of the bag body 1. The mounting plate 2 connects the bag body 1 to other equipment. After the bag body 1 is removed, the sealing plate 4 on one side of the mounting plate 2 is moved to seal the inlet 3 and prevent dust leakage. At this time, the limiting device 5 is used to limit the position of the sealing plate 4 on the mounting plate 2. When using the sealing plate 4, the sliding block 52 is moved so that it moves in the sliding groove 51 on one side of the mounting plate 2. Then, the sliding block 52 drives the sealing plate 4 fixed on one side to reach the inlet 3 on one side of the bag body 1 to seal the inlet 3. Then, the bolt 53 is rotated so that the bolt 53 rotates inside the threaded groove 54 on one side of the mounting plate 2 to form a threaded connection. This completes the limiting and fixing of the positions of the sliding block 52 and the sealing plate 4. When the sealing plate 4 is not in use, the sliding block 52... Move the sealing plate 4 away from the ash inlet 3 on the side away from the bag body 1, and then rotate the bolt 53 so that one end of the bolt 53 abuts against the inner wall of the sliding groove 51 of the mounting plate 2 to complete the position limit of the sealing plate 4. By using the limiting device 5, the position of the sealing plate 4 on the mounting plate 2 can be limited, so as to avoid the situation where the sealing plate 4 does not limit the ash inlet 3 when it is blocking the ash inlet 3, and then the sealing plate 4 is separated from the ash inlet 3 on the side of the bag body 1 after being subjected to force, thereby improving the use effect of the sealing plate 4, and thus improving the use effect of the dust bag.
