AI Technical Summary
The existing central dust collection system's dust suction inlet lacks a sealing mechanism, resulting in poor sealing at the interface.
The design employs a combination of threaded connection between internal and external threaded cylinders, along with a clamping block and a fluorocarbon rubber plate. The flange is mounted via external bolts, and the cooperation of springs, connecting plates, and connecting seats ensures that the fluorocarbon rubber plate is tightly attached to the surface of the suction pipe while allowing rotation, thus guaranteeing sealing and robustness.
It enables convenient disassembly and high-sealing connection of the suction pipe and the inlet, avoiding dust leakage and improving the overall cleaning effect of the central dust removal system.

Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, specifically a dust suction port for a central dust removal system. Background Technology
[0002] A central dust collection system is a cleaning system capable of large-area dust removal and preventing secondary pollution. By placing the main unit outdoors and laying pipes to various locations, and connecting to the inlet at one end of the pipe, the main unit can be activated to suck indoor dust to the outside, facilitating the cleaning of large areas. At the same time, the dust is directly sucked to the outside, avoiding secondary pollution. However, existing vacuum inlets use a direct snap-fit method, which lacks a sealing mechanism, resulting in poor sealing at the interface. Therefore, we propose a vacuum inlet for a central dust collection system. Utility Model Content
[0003] The purpose of this invention is to provide a vacuum inlet for a central dust removal system to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a dust suction inlet for a central dust removal system, comprising an internally threaded cylinder, an externally threaded cylinder being threadedly connected to the right side of the internally threaded cylinder, and a retainer being fixedly connected to the right side of the externally threaded cylinder, wherein the retainer has multiple equally spaced slots on its right side, a retaining block being inserted into the inner side of the slot, and a dust suction pipe being fixedly connected to the inner side of the retaining block.
[0005] Preferably, a flange is fixedly connected to the left side of the internally threaded cylinder, and mounting holes are provided around the inner surface of the flange.
[0006] Preferably, the right side of the external threaded cylinder has multiple equidistant reserved slots, a spring is fixedly connected to the left side of the cavity of the reserved slot, and a connecting plate is fixedly connected to the right side of the spring.
[0007] Preferably, a limiting block is fixedly connected to the outer side of the connecting plate, and a limiting groove is opened in the inner cavity of the external threaded cylinder and located outside the reserved groove, and the limiting block is slidably connected in the inner cavity of the limiting groove.
[0008] Preferably, a first connecting rod is fixedly connected to the right side of the connecting plate, and a connecting seat is fixedly connected to the right side of the first connecting rod, with a sliding groove provided in the inner cavity of the connecting seat.
[0009] Preferably, a slider is slidably connected to the inner side of the groove, a second connecting rod is fixedly connected to the inner side of the slider, and a fluorocarbon rubber plate is fixedly connected to the right side of the second connecting rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This invention uses an external bolt to install the flange onto the main unit through the mounting hole. The external threaded cylinder is threaded onto the surface of the internal threaded cylinder, which facilitates disassembly while ensuring overall sealing. Then, the clamp is inserted from the slot, and the suction pipe is rotated to quickly connect the suction pipe to the clamp. During this process, the suction pipe squeezes the fluorocarbon rubber plate, and with the cooperation of the spring, connecting plate, first connecting rod, and connecting seat, the fluorocarbon rubber plate is tightly attached to the surface of the suction pipe. At the same time, due to the action of the slide, slider, and second connecting rod, the fluorocarbon rubber plate has the ability to rotate, so that the fluorocarbon rubber plate will rotate with the suction pipe, preventing the spring from generating torque and deforming, thus ensuring the firmness and sealing of the connection.

The ferrule 3 has multiple equally spaced slots 7 on its right side, a locking block 8 is inserted into the inner side of the slot 7, and a suction pipe 4 is fixedly connected to the inner side of the locking block 8. A flange 2 is fixedly connected to the left side of the internally threaded cylinder 1, and mounting holes 6 are opened around the inner surface of the flange 2. The flange 2 is installed on the main unit by external bolts passing through the mounting holes 6, and the externally threaded cylinder 5 is threadedly connected to the surface of the internally threaded cylinder 1, which facilitates disassembly while ensuring overall sealing.

[0022] Please see Figure 3 and Figure 4 The following technical solution is provided, specifically disclosing that: Multiple equidistant reserved grooves 9 are provided on the right side of the external threaded cylinder 5; a spring 10 is fixedly connected to the left side of the inner cavity of the reserved groove 9; a connecting plate 11 is fixedly connected to the right side of the spring 10; a limiting block 12 is fixedly connected to the outer side of the connecting plate 11; a limiting groove 19 is provided in the inner cavity of the external threaded cylinder 5, located outside the reserved groove 9; the limiting block 12 is slidably connected to the inner cavity of the limiting groove 19; a first connecting rod 18 is fixedly connected to the right side of the connecting plate 11; a connecting seat 13 is fixedly connected to the right side of the first connecting rod 18; a sliding groove 17 is provided in the inner cavity of the connecting seat 13; a slider 14 is slidably connected to the inner side of the sliding groove 17; and a fixed block 12 is fixedly connected to the inner side of the slider 14. The second connecting rod 16 has a fluorocarbon rubber plate 15 fixedly connected to its right side. When the locking block 8 is inserted into the locking slot 7 and the vacuum tube 4 is rotated, the vacuum tube 4 can be quickly connected to the locking sleeve 3. During this process, the vacuum tube 4 will squeeze the fluorocarbon rubber plate 15, and with the cooperation of the spring 10, the connecting plate 11, the first connecting rod 18 and the connecting seat 13, the fluorocarbon rubber plate 15 will be tightly attached to the surface of the vacuum tube 4. At the same time, due to the action of the sliding groove 17, the slider 14 and the second connecting rod 16, the fluorocarbon rubber plate 15 can rotate, so that when the vacuum tube 4 rotates, the fluorocarbon rubber plate 15 will also rotate, and the spring 10 will not be deformed by torque, thus ensuring the firmness and sealing of the connection.
[0023] The working principle of this application is as follows: the flange 2 is installed on the main unit by passing through the mounting hole 6 with an external bolt, and the external threaded cylinder 5 is threaded to the surface of the internal threaded cylinder 1. This facilitates disassembly while ensuring overall sealing. Then, the clamp 8 is inserted from the slot 7, and the suction pipe 4 is rotated to quickly connect the suction pipe 4 to the clamp 3. During this process, the suction pipe 4 will squeeze the fluorocarbon rubber plate 15, and with the cooperation of the spring 10, the connecting plate 11, the first connecting rod 18 and the connecting seat 13, the fluorocarbon rubber plate 15 will be tightly attached to the surface of the suction pipe 4. At the same time, due to the action of the slide groove 17, the slider 14 and the second connecting rod 16, the fluorocarbon rubber plate 15 can rotate. Thus, when the suction pipe 4 rotates, the fluorocarbon rubber plate 15 will also rotate, preventing the spring 10 from generating torque and deforming, thus ensuring the firmness and sealing of the connection.
