[0001] This utility model relates to the technical field of dust collection equipment, and more specifically, to a dust collection pipe with adjustable angle and extendable length. Background Technology

[0002] Industrial production processes, such as wood processing, metal polishing, and chemical production, generate a large amount of dust. This dust not only pollutes the working environment and affects the health of workers, but may also cause safety accidents such as explosions.

[0003] Existing publication number CN215613961 U discloses an adjustable dust collector, including a power supply, dust collection and processing equipment, a dust collection pipe, a connection port, and a suction port. The dust collection pipe has a movable support frame inside, which includes support rods and a rotating shaft. The movable support frame is composed of multiple support rods and can extend and retract at any angle. The rotating shaft allows the dust collection pipe to be suspended at any angle, and it can rotate 360 ​​degrees. Therefore, according to operational needs, the dust collection pipe can be adjusted to multiple angles using the combined action of the movable support frame and the rotating shaft to achieve optimal dust collection. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] The length and angle of existing pipelines are mostly fixed. In actual use, the layout of different production equipment and the working space vary. Pipelines with fixed lengths and angles cannot flexibly adapt to various complex working conditions and cannot accurately cover dust sources, resulting in incomplete dust collection and affecting the collection effect. On the other hand, stability issues are prominent during pipeline installation and use. Some pipelines lack effective fixing and anti-loosening designs at the connection points, which can easily lead to loosening or displacement due to equipment vibration or external forces, thereby affecting the continuity and stability of dust collection.

[0005] Therefore, a dust collection pipe with adjustable angle and extendable length is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dust collection pipe with adjustable angle and extendable length to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust collection pipe with adjustable angle and extendable length, comprising a telescopic pipe, one end of which is connected to a dust collection port, the dust collection port being funnel-shaped, a fixing plate being fixedly installed on the inner wall of the dust collection port, a dust collection motor being detachably installed above the fixing plate, and a fan blade being detachably installed on the top of the dust collection motor, the fan blade rotating at high speed under the drive of the dust collection motor; in addition, a positioning sleeve is provided at the end of the telescopic pipe away from the dust collection port, the positioning sleeve being used to fix the end position of the pipe, a clamping ring being detachably fitted on the outer side of the positioning sleeve, the clamping ring being able to fit against the positioning sleeve, and an anti-slip pad being provided on the inner wall of the clamping ring.

[0008] Preferably, the dust collection port has an annular groove inside, the groove extends circumferentially along the inner wall of the dust collection port, and the inner wall of the groove has positioning holes evenly distributed.

[0009] Preferably, the interior of the groove has sufficient space to detachably place the protective net. The protective net has evenly distributed threaded holes on its upper surface, and a ground nail is threadedly installed on the upper surface of the protective net. The ground nail has external threads that match the threaded holes. During installation, the ground nail is screwed into the threaded holes to connect the ground nail to the protective net.

[0010] Preferably, a handle is fixedly installed on the outer edge of the dust collection port and the telescopic tube, and the handle is positioned symmetrically on both sides of the dust collection port.

[0011] Preferably, a positioning frame is fixedly installed at the bottom of the dust collection port. The shape of the positioning frame is designed according to the bottom contour of the dust collection port. The positioning frame fits the dust collection port. Several threaded holes are evenly distributed on the upper side of the positioning frame. A positioning bolt is threadedly installed on the upper side of the positioning frame. The positioning bolt has a matching external thread.

[0012] Preferably, the clamping ring is fitted onto the positioning sleeve, the inner wall of the clamping ring is in contact with the outer wall of the positioning sleeve, and a threaded hole is provided on the upper side of the clamping ring. A fastening bolt is installed in the internal thread of the threaded hole, and the fastening bolt has an external thread that matches the threaded hole.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this dust collection pipe with adjustable angle and extendable length allows the pipe length to be freely adjusted according to different working scenarios and equipment layouts through the design of the telescopic pipe. It can accurately cover the dust generation source and effectively solve the problem that the existing pipes have fixed lengths and are difficult to adapt to complex working conditions. At the same time, through the reasonable design of the angle adjustment structure, the pipe angle can be easily adjusted, further enhancing the pipe's adaptability to different spaces.

[0015] Compared with existing technologies, this dust collection pipe with adjustable angle and extendable length uses a positioning sleeve and a clamping ring to cooperate. The anti-slip pad on the inner wall of the clamping ring increases the friction with the positioning sleeve. Then, it is locked with fastening bolts to firmly fix the end position of the pipe. This effectively avoids the pipe from loosening or shifting due to equipment vibration or external force, and ensures the continuity and stability of dust collection.

[0016] In addition, the protective net at the dust collection port is detachable and easy to clean and replace regularly, ensuring dust collection efficiency while extending the service life of the equipment; the handles symmetrically arranged on both sides of the dust collection port make it easy to move and adjust the position of the pipe; the design of the bottom positioning frame and positioning bolts can assist in positioning the dust collection port, further improving the stability of the entire pipeline system and fully meeting the needs of dust collection in industrial production.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0028] In a preferred embodiment, the dust collection port 2 has an annular groove 6 inside. The groove 6 extends circumferentially along the inner wall of the dust collection port 2, providing suitable space for the installation of subsequent components. The inner wall of the groove 6 is evenly distributed with positioning holes 7. The positioning holes 7 are of the same size and evenly spaced. They not only provide positioning points for the installation of dust collection-related components to ensure that the installation position is correct, but also fix the components in the groove 6 by cooperating with the matching positioning pin components, preventing loosening or displacement due to vibration or other reasons during the dust collection process.

[0029] In a preferred embodiment, the interior of the groove 6 has sufficient space for the detachable placement of the protective net 11. The protective net 11 is made of high-strength, wear-resistant material, which can effectively block larger particles of debris from entering the pipe, avoiding blockage or damage to subsequent dust collection equipment and pipes, while ensuring the smooth passage of air and fine dust. Threaded holes are evenly distributed on the top of the protective net 11, and ground nails 12 are threadedly installed on the top of the protective net 11. The ground nails 12 have external threads that match the threaded holes. During installation, the ground nails 12 are screwed into the threaded holes to connect with the protective net 11. Then, through the cooperation between the ground nails 12 and the bottom of the groove 6, the protective net 11 is firmly fixed inside the groove 6.

[0030] As a preferred embodiment, a handle 8 is fixedly installed on the outer edge of the dust collection port 2 and the telescopic pipe 1. The handle 8 is made of a sturdy and durable material with a certain anti-slip property, ensuring a comfortable grip and preventing slippage. The handle 8 is set symmetrically on both sides of the dust collection port 2, making it convenient for workers to grab from different directions. Moreover, it provides a stable and labor-saving force application point when moving, adjusting the angle of the dust collection port 2, or moving the entire dust collection pipe, greatly improving the convenience and flexibility of operation and effectively reducing the labor intensity of workers.

[0031] In a preferred embodiment, a positioning frame 9 is fixedly installed at the bottom of the dust collection port 2. The positioning frame 9 is made of high-strength, deformation-resistant metal material, with a solid and reliable structure, which can provide stable support for the dust collection port 2. The shape of the positioning frame 9 is designed according to the bottom contour of the dust collection port 2. The positioning frame 9 fits the dust collection port 2. Several threaded holes are evenly distributed on the upper side of the positioning frame 9. A positioning bolt 10 is threaded on the upper side of the positioning frame 9. The positioning bolt 10 has a matching external thread. During installation, the positioning bolt 10 is precisely screwed into the threaded hole. By adjusting the screwing depth of the positioning bolt 10, the height and angle of the dust collection port 2 can be flexibly adjusted so that it can be accurately positioned and stably installed in the required working position.

[0032] In a preferred embodiment, the clamping ring 14 is fitted onto the positioning sleeve 13. The inner wall of the clamping ring 14 fits and contacts the outer wall of the positioning sleeve 13, ensuring a tight connection and preventing loosening or shaking during use. A threaded hole is provided on the upper side of the clamping ring 14, and a fastening bolt 15 is installed in the internal thread of the threaded hole. The fastening bolt 15 has an external thread that matches the threaded hole. During installation, the fastening bolt 15 is screwed into the threaded hole. As the fastening bolt 15 is continuously screwed in, the end of the fastening bolt 15 will gradually press against the positioning sleeve 13. Through continuous tightening, the clamping force of the clamping ring 14 on the positioning sleeve 13 can be further enhanced, making the entire connection more stable and reliable.

[0033] In this embodiment, the telescopic tube 1 is a commercially available device known to those skilled in the art. The model can be selected or customized according to actual needs. Here we are only using it without making any structural or functional improvements, so we will not go into details here.

[0034] The working process of this utility model is as follows: First, place the protective net 11 into the groove 6 inside the dust collection port 2, and screw the ground nail 12 into the threaded hole above the protective net 11 to complete the installation of the protective net 11; next, adjust the angle of the dust collection port 2 using the positioning bracket 9 and the positioning bolt 10. The positioning bracket 9 fits against the bottom of the dust collection port 2, and the positioning bolt 10 is screwed into the threaded hole on the upper side of the positioning bracket 9 for fixation; then, start the dust collection motor 4, and its top fan blade 5 rotates at high speed, forming a negative pressure at the dust collection port 2, and the dust is drawn out in a funnel shape. The dust collection port 2 is inserted into the telescopic tube 1. Next, depending on the actual usage scenario, the telescopic tube 1 is stretched or compressed to a suitable length. Then, the positioning sleeve 13 is placed at the target position, and the clamping ring 14 is placed on the outside of the positioning sleeve 13, ensuring the anti-slip pad on the inner wall of the clamping ring 14 fits against the positioning sleeve 13. The fastening bolt 15 is then screwed into the threaded hole on the upper side of the clamping ring 14 and tightened to fix the end position of the telescopic tube 1. Finally, the handles 8 symmetrically installed on both sides of the dust collection port 2 can be easily moved and adjusted. The above describes the working principle of this angle-adjustable and length-extendable dust collection pipe.
