[0002] In industrial production processes, bag-type dust collectors are widely used for dust treatment, and the stability and sealing of their piping systems are crucial to ensuring dust removal efficiency. However, existing bag-type dust collection pipe connection methods often have problems such as difficulty in tightening, poor sealing performance, and susceptibility to loose connections due to temperature and vibration. These problems not only affect the dust removal effect, but may also cause dust leakage, causing harm to the environment and human health. In existing technologies, the fastening structure of the dust removal pipe usually adopts a simple bolt fastening method. Although it can achieve basic fixing effects, it has many deficiencies in actual applications. For example, the lack of an effective adjustment mechanism makes it impossible to adapt to pipes of different diameters or shapes, resulting in uneven fastening or loose sealing, which in turn leads to a decrease in the sealing performance of the joints. In addition, some fastening structures require the use of complex tools during installation and adjustment, which increases the difficulty and cost of maintenance. Utility Model Content

[0029] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0030] In order to solve the technical problems in the background technology, such as Figure 1-4 As shown, the present application provides a technical solution: a special fastening structure for a dust collector pipe, which has the following characteristics:

[0031] The fixing base 1 adopts a U-shaped design and is preferably made of high-strength steel or aluminum alloy to ensure structural stability and durability. Multiple through-holes 2 are provided on the side walls of the fixing base 1, each of which is used to mount a clamp 3. The clamp 3 is fixedly installed in the through-hole 2 of the fixing base 1, either by pin fixation, welding, or fastening with screws and nuts. The through-hole 2 can be a simple circular hole or a threaded hole to facilitate fastening with bolts or screws. The clamp 3 consists of a first clamp body 4 and a second clamp body 5, which are connected by a hinged structure to allow a certain degree of relative movement. One end of the first clamp body 4 is provided with a limit slot 6 for mounting an adjustment and positioning mechanism 7, and the other end is hingedly connected to the second clamp body 5. One end of the second clamp body 5 is provided with a slot 8 for securing the hinged column 9 and forming a fastening structure. The adjustment and positioning mechanism 7 includes a hinged column 9, a gasket 10, a spring 11, an adjustment sleeve 12, and an adjustment buckle 13. One end of the hinged column 9 is hinged to the first hoop body 4 at the limiting groove 6, and the other end is provided with an external thread for connecting to the internal thread hole of the adjustment buckle 13. The gasket 10 and the spring 11 are sequentially mounted on the hinged column 9. The gasket 10 is used to abut the spring 11, and the spring 11 is used to provide a preload force to ensure that the first hoop body 4 and the second hoop body 5 have an elastic fastening space at the non-hinged end. The adjustment sleeve 12 is a hollow cylinder with a symmetrical arc-shaped undulating surface at one end for cooperating with the adjustment buckle 13. One end of the adjustment buckle 13 is cylindrical and adapts to the arc surface of the adjustment sleeve 12, and the other end is connected to the adjustment sleeve 12 via an eccentric hinge shaft 14. An internal threaded hole is provided in the middle radial direction of the eccentric hinge shaft 14, which is connected to the external thread of the hinged column 9, allowing the adjustment buckle 13 to rotate axially around the hinge shaft 14 to adjust the fastening force of the first hoop body 4 and the second hoop body 5. The hinge post 9 is inserted into the slot 8, and the adjustment sleeve 12 is located on the side of the second hoop body 5 away from the first hoop body 4. In simple terms, the adjustment sleeve 12 is located on the outer wall of the second hoop body 5. At this time, the hoop 3 is enclosed to form a tight structure. By rotating the adjustment buckle 13, the distance between the hinge axis 14 and the second hoop body 5 is adjusted. When the distance is farthest, the first hoop body 4 and the second hoop body 5 are most tightly connected. At this time, the other end of the adjustment buckle 13 is in contact with the outer wall of the second hoop body 5, forming a stable tight structure.

[0032] It should be noted that the reinforcing ribs 15 are provided on the outer sidewall of the first hoop body 4 and may be continuous or discontinuous to increase the rigidity and strength of the first hoop body 4. The reinforcing ribs 15 are curved ribs, formed according to the shape of the outer sidewall of the first hoop body 4, to provide additional support and strength, enabling the first hoop body 4 to withstand greater pressure and torque, thereby improving the stability of the entire fastening structure.

[0033] Furthermore, to improve the installation efficiency and reliability of the dedicated fastening structure for the dust collector duct, the through hole 2 is designed as a threaded hole so that a screw can be screwed in to fix the clamp 3 to the fixing base 1. The length of the screw should be determined according to the thickness of the fixing base 1 and the clamp 3 and the required fastening force.

[0034] It should be noted that in order to further improve the stability and installation convenience of the special fastening structure of the dust collector duct, a groove 16 is provided in the middle of the first hoop body 4 in this embodiment, and the groove 16 is adapted to the fixing seat 1. The groove 16 is provided in the middle part of the first hoop body 4, and its shape and size are designed to be adapted to the corresponding U-shape of the fixing seat 1. The main functions of the groove 16 are, firstly, to enable the clamp 3 to be installed on the fixing seat 1 more stably, and secondly, to facilitate the hiding of the fixing screw without affecting the sealing of the dust bag. When the clamp 3 is installed on the fixing seat 1, the groove 16 cooperates with the raised part of the fixing seat 1 to prevent the clamp 3 from rotating or moving during use.

[0035] Furthermore, a center hole 17 is added in the groove 16 of the first hoop body 4. The center hole 17 is adapted to the through hole 2 and is used to pass the screw to connect the first hoop body 4 to the fixing base 1. The center hole 17 is precisely set at the center position of the groove 16, and its diameter and shape are adapted to the through hole 2. The size design of the center hole 17 is to ensure that the screw can pass through smoothly while ensuring sufficient structural strength. The use of the center hole 17 in conjunction with the through hole 2 can improve the installation accuracy of the clamp 3 and ensure that the clamp 3 is centered on the fixing base 1.

[0036] It should be noted that one end of the adjusting sleeve 12 is designed to have an arc-shaped undulating surface, and this arc-shaped undulating surface is specifically a concave surface 18, so as to fully adapt to the hinged end cylinder of the adjusting buckle 13. The concave surface 18 of the adjusting sleeve 12 is designed so that the inner surface or outer surface of one end thereof is a smooth concave arc. The shape of the concave surface 18 can be a semicircle, a quarter circle or other suitable arc to ensure a perfect match with the hinged end cylinder of the adjusting buckle 13. The main function of the concave surface 18 is to provide a surface that adapts to the hinged end cylinder of the adjusting buckle 13, so that the adjusting buckle 13 can be flexibly rotated on the adjusting sleeve 12 to adjust the tightening force of the clamp 3. The design of the concave surface 18 helps to improve the smoothness and accuracy of the operation of the adjustment and positioning mechanism 7, and ensure that the clamp 3 can evenly and tightly surround the dust collector bag pipe. To adjust the tightening force of the clamp 3, the user can hold the adjustment buckle 13 and rotate it around the hinge shaft 14. The hinged end cylinder of the adjustment buckle 13 will move along the concave surface 18 of the adjustment sleeve 12. Because the hinge shaft 14 is eccentric, the user can increase or decrease the tightening pressure of the clamp 3 on the pipe by rotating the adjustment buckle 13 clockwise or counterclockwise.

[0037] It should be noted that a non-slip washer 19 is added to the lower end of the fixing base 1. Non-slip washer 19 is coaxially arranged with through hole 2 and has the same inner diameter as through hole 2. Non-slip washer 19 is designed as an annular washer and can be made of rubber, plastic, or other materials with a good coefficient of friction to provide sufficient non-slip effect. Its main function is to increase the friction between the fixing base 1 and the fixing nut.

[0038] It should be noted that to improve the locking stability of the dust collector duct fastening structure and prevent the adjustment sleeve 12 from sliding into the slot 8 under high pressure or unexpected impact, the outer diameter of the adjustment sleeve 12 is 5-10 mm larger than the width of the slot 8. This provides an appropriate fit clearance when the adjustment sleeve 12 is locked into the slot 8. The main function of the adjustment sleeve 12 is to provide an adjustable locking mechanism. When the outer diameter of the adjustment sleeve 12 is larger than the width of the slot 8, the adjustment sleeve 12 is locked in the slot 8, which helps prevent the adjustment sleeve 12 from accidentally sliding out.

[0039] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
