Description

Technical Field

[0001] The utility model belongs to the technical field of drag chain equipment, and particularly relates to a drag chain noise reduction trough. Background Art

[0002] Drag chains are generally used to pull and protect cables, oil pipes, air pipes, water pipes, and air ducts in machine tools and other machinery. They are widely used in CNC electronic equipment, stone and glass machinery, manipulators, lifting and transportation equipment, automated warehouses, and robotic arms.

[0003] During long-term use, it was found that when the drag chain moves back and forth quickly, its chain links will collide with the hard limit grooves used with it. This not only produces loud noise, but also makes the drag chain prone to wear under long-term impact, shortening its service life. Utility Model Content

[0004] The purpose of the utility model is to provide a drag chain noise reduction groove, which is used to solve the problem that the existing drag chain directly collides with the hard limit groove.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A drag chain noise reduction trough, comprising:

[0007] A trough body, wherein the cross section of the trough body is U-shaped;

[0008] A buffer pad, the buffer pad is located in the tank body and has a U-shaped cross section;

[0009] The buffer pad comprises a bottom pad and side pads located on both sides of the bottom pad.

[0010] It is further defined that the inner wall of the side pad is inclined outward from bottom to top.

[0011] This structural design, through the inclination of the side pads, makes the opening on the upper part of the buffer pad larger. While ensuring that the width of the lower part of the buffer pad remains unchanged, forming an effective constraint on the drag chain, the larger opening makes it easier for the drag chain to enter the noise reduction groove, which is more practical.

[0012] It is further defined that the outer walls on both sides of the upper portion of the trough body are provided with flanges;

[0013] The upper portion of the side pad is integrally formed with a fixed edge covering the flange.

[0014] This structural design completes the connection between the buffer pad and the trough body through the cooperation of the fixed edge and the flange. It has a simple structure, is easy to assemble and disassemble, and is highly practical.

[0015] It is further defined that a special-shaped steel bar is embedded in the fixed edge, and the special-shaped steel bar covers the flange and extends into the side pad.

[0016] This structural design strengthens the structural strength of the fixed edge through special-shaped steel bars, thereby strengthening the connection stability between the buffer pad and the trough body, and is more practical.

[0017] It is further defined that a slot is provided on the edge of the flange, a limit block is provided on the fixed edge, and the limit block is locked in the slot.

[0018] Such a structural design completes the position limitation between the slot body and the buffer pad in the length direction through the cooperation between the card slot and the limit block, and is highly practical.

[0019] It is further defined that the bottom pad and / or the side pad are both provided with a blind hole on one side close to the trough body.

[0020] Such a structural design, through the setting of the blind hole, allows the buffer pad to be placed in the slot body, and the volume of the blind hole can be reduced by pressing the buffer pad. After the pressure is released, the volume of the blind hole is restored due to the action of the buffer pad's own elasticity, thereby forming a negative pressure in the blind hole, thereby adsorbing the buffer pad on the slot body, further enhancing the connection strength between the buffer pad and the slot body, and having strong practicality.

[0021] It is further defined that there are multiple buffer pads, and the multiple buffer pads are distributed in sequence along the length direction of the trough body.

[0022] This structural design divides the buffer pad into multiple parts, so that when part of the buffer pad is excessively worn, it can be maintained by replacing it in sections, without replacing the entire buffer pad, saving maintenance costs and being more practical.

[0023] It is further defined that one end of the buffer pad is provided with a T-shaped block and the other end is provided with a T-shaped slot.

[0024] Such a structural design, through the mutual cooperation of the T-shaped card block and the T-shaped card slot, can use the T-shaped card block to clamp the T-shaped card slot of another buffer pad when there are multiple buffer pads, thereby realizing the connection between two adjacent buffer pads, which is highly practical.

[0025] It is further defined that the T-shaped card block and the T-shaped card slot are both provided on the bottom pad.

[0026] This structural design, by arranging the T-shaped block and the T-shaped slot on the bottom pad, utilizes the up and down movement of the buffer pad during installation to complete the setting of the T-shaped block and the T-shaped slot. It has a simple structure, is easy to install, and is highly practical.

[0027] The utility model adopting the above technical solution has the following advantages:

[0028] 1. The buffer pad is used to buffer the space between the tank body and the chain links of the drag chain, preventing the tank body from directly hitting the bottom wall and side wall of the tank body. While reducing noise, it also reduces the wear of the drag chain and extends the service life of the drag chain, which is more practical.

[0029] 2. The tilt of the side pads makes the opening on the top of the cushion larger. While ensuring the width of the bottom of the cushion remains unchanged, it effectively restrains the drag chain. The larger opening makes it easier for the drag chain to enter the noise reduction groove, which is more practical.

[0030] 3. By dividing the buffer pad into multiple parts, when part of the buffer pad is excessively worn, it can be maintained by replacing it in sections, without replacing the entire buffer pad, thus saving maintenance costs and being more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts in the drawings or in the specification are numbered the same. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back" mentioned in the embodiments are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0041] like Figures 1 to 3 As shown, a drag chain noise reduction trough of the utility model includes:

[0042] The trough body 1 has a U-shaped cross section;

[0043] The buffer pad 2 is located in the tank body 1 and has a U-shaped cross section;

[0044] The cushion pad 2 includes a bottom pad 22 and side pads 21 located on both sides of the bottom pad 22 .

[0045] The inner wall of the side pad 21 is inclined outward from bottom to top.

[0046] In fact, the inner wall of the side pad 21 can also be set to a vertical shape according to actual conditions. In this embodiment, the opening of the upper part of the buffer pad 2 is larger by tilting the side pad 21. While ensuring that the width of the lower part of the buffer pad 2 remains unchanged, forming an effective constraint on the drag chain, the larger opening makes it easier for the drag chain to enter the noise reduction groove, which is more practical.

[0047] The outer walls on both sides of the upper part of the tank body 1 are provided with flanges 11;

[0048] A fixing edge 210 covering the flange 11 is integrally formed on the upper portion of the side pad 21 .

[0049] In fact, according to actual conditions, a connection method such as glue can be directly selected to complete the connection between the buffer pad 2 and the trough body 1. In this embodiment, the connection between the buffer pad 2 and the trough body 1 is completed by cooperating with the fixed edge 210 and the flange 11. The structure is simple, the assembly and disassembly is convenient, and the practicability is strong.

[0050] A special-shaped steel bar 211 is embedded in the fixed edge 210 . The special-shaped steel bar 211 covers the flange 11 and extends into the side pad 21 .

[0051] The structural strength of the fixed edge 210 is enhanced by the special-shaped steel bar 211 , thereby strengthening the connection stability between the buffer pad 2 and the trough body 1 , and the practicality is strong.

[0052] A slot 12 is formed on the edge of the flange 11 , and a limit block 212 is provided on the fixed edge 210 . The limit block 212 is locked in the slot 12 .

[0053] In fact, according to actual conditions, a connection method such as glue can be directly selected to complete the connection between the buffer pad 2 and the slot body 1. This embodiment completes the position limitation in the length direction between the slot body 1 and the buffer pad 2 through the cooperation between the card slot 12 and the limit block 212, which is more practical.

[0054] A blind hole 23 is formed on the bottom pad 22 and / or the side pad 21 close to the tank body 1 .

[0055] Through the provision of the blind hole 23, after the buffer pad 2 is placed in the slot body 1, the buffer pad 2 can be pressed to reduce the volume of the blind hole 23. After the pressure is released, the buffer pad 2 restores the volume of the blind hole 23 under the action of its own elasticity, thereby forming a negative pressure in the blind hole 23, thereby adsorbing the buffer pad 2 on the slot body 1, further enhancing the connection strength between the buffer pad 2 and the slot body 1, and having strong practicality.

[0056] There are multiple buffer pads 2 , which are distributed in sequence along the length direction of the tank body 1 .

[0057] In fact, according to actual conditions, an integral buffer pad 2 can be provided in the trough body 1. In this embodiment, the buffer pad 2 is divided into multiple parts, so that after part of the buffer pad 2 is excessively worn, it can be maintained by replacing it in sections, without replacing the entire buffer pad 2, thus saving maintenance costs and being more practical.

[0058] One end of the buffer pad 2 is provided with a T-shaped block 221 , and the other end is provided with a T-shaped slot 222 .

[0059] Through the mutual cooperation between the T-shaped block 221 and the T-shaped slot 222, when there are multiple buffer pads 2, the T-shaped block 221 can be used to clamp the T-shaped slot 222 of another buffer pad 2 to achieve the connection between two adjacent buffer pads 2, which is more practical.

[0060] The T-shaped block 221 and the T-shaped slot 222 are both disposed on the bottom pad 22 .

[0061] In fact, the T-shaped block 221 and the T-shaped slot 222 can also be set on the side pad 21 according to actual conditions. In this embodiment, the T-shaped block 221 and the T-shaped slot 222 are set on the bottom pad 22, and the up and down movement of the buffer pad 2 during installation is utilized to complete the setting of the T-shaped block 221 and the T-shaped slot 222. The structure is simple, the installation is convenient, and the practicality is strong.

[0062] In this embodiment, during installation, the fixed edges 210 on both sides of the buffer pad 2 are first hung on the flanges 11 of the trough body 1, and the limit blocks 212 are locked in the locking grooves 12. Then, the bottom pad 22 of the buffer pad 2 is pressed down so that the bottom pad 22 is pressed against the bottom of the trough body 1. The pressing is continued to reduce the volume of the blind hole 23 of the bottom pad 22, and the bottom pad 22 is adsorbed on the bottom of the trough body 1 by using the blind hole 23.

[0063] Then, the side pads 21 are squeezed toward both sides, and the blind holes 23 of the side pads 21 are utilized to make the side pads 21 adsorbed on the side walls of the tank body 1 .

[0064] The above describes in detail the noise reduction trough for a drag chain provided by the present invention. The description of the specific embodiment is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
