Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a clamp structure for clamping profiles. Background Technology

[0002] Currently, when metal profiles undergo surface treatments such as electroplating, electrophoresis, and anodizing, clamps are required to hold and fix the metal profiles and immerse them in an electrolyte solution to prevent them from floating or moving in the electrolyte solution, thus ensuring the uniformity and smoothness of the coating.

[0003] In existing clamps, such as the Chinese patent document that discloses a technical solution with patent application number 200920265085.0 entitled "An Oxidation Line Clamp," this type of clamp has only one clamping opening. During the clamping process, the profile is prone to rotation and swinging around the clamp as an axis, resulting in loosening and falling off, making the reliability of this single-head clamp low. To solve this technical problem, the applicant previously filed a patent application with the Patent Office of the State Intellectual Property Office of China with patent application number 202322230789.7 entitled "A Sheet Metal Clamp." This solution mainly includes a mounting base and two clamping components arranged horizontally side by side on the mounting base. Each of the two clamping components has a clamping opening, and the two clamping openings are at the same horizontal height. This allows the metal profile to be clamped at two positions on the same plane in different vertical directions through the two clamping openings, thereby improving the stability and firmness of the clamping. However, in practical applications, this solution still has some shortcomings: Since the two clamping ports are at the same horizontal level, it is only limited to providing a very stable fixing effect on sheet profiles. For tubular profiles, it can only be clamped to one side. Due to the influence of its center of gravity, the clamped and suspended tubular profile is prone to tilting and swaying. This not only causes the clamped part of the profile to bend and deform easily, but also makes it easy to loosen and fall off. Therefore, the clamping and fixing of tubular profiles by this double-headed clamp is not stable and reliable enough.

[0004] Therefore, given the aforementioned shortcomings of existing profile clamps, it is essential to further improve their structure in order to better meet people's application needs. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a double-layer clamping structure for clamping profiles. This double-layer clamping structure can clamp and fix both sides of the tubular profile respectively. After the tubular profile is lifted, it can better control the balance of the tubular profile to provide stable support, prevent it from tilting to the side, and prevent the clamped part of the profile from bending and deforming. This greatly reduces the probability of loosening or falling off, thereby greatly improving the stability and firmness of clamping and fixing the tubular profile.

[0006] The technical solution of this utility model is implemented as follows: a double-layer clamping structure for clamping profiles includes a mounting base, a first clamping component with a first clamping port, and a second clamping component with a second clamping port. The first clamping component and the second clamping component are arranged in a stacked and spaced manner on the mounting base, and the first clamping port and the second clamping port are arranged in a parallel and spaced manner.

[0007] Preferably, there are multiple first clamping components, and each first clamping component is arranged at horizontal intervals.

[0008] Preferably, there are multiple second clamping components, and each second clamping component is arranged horizontally at intervals.

[0009] Preferably, the mounting base includes a first mounting frame, a second mounting frame, and a connecting frame. The second mounting frame and the first mounting frame are connected together by the connecting frame, and the second mounting frame and the first mounting frame are arranged in a stacked and spaced manner. The first clamping component is disposed on the first mounting frame, and the second clamping component is disposed on the second mounting frame.

[0010] Preferably, the present invention further includes a locking bolt, wherein the connecting frame and the second mounting frame are an integral structure, and the connecting frame and the first mounting frame are detachably fixed together by the locking bolt.

[0011] Preferably, the first or second mounting bracket is further provided with fixing holes.

[0012] Preferably, the first clamping assembly and the second clamping assembly each include a main clamping seat, a movable clamp, a fixed clamp, a pull rod, a connecting rod, and a tension spring. The fixed clamp is disposed on the main clamping seat. One end of the pull rod and the movable clamp are respectively rotatably hinged to the main clamping seat, and the pull rod drives the movable clamp to move closer to or away from the fixed clamp through the connecting rod. The two ends of the tension spring are respectively connected to the pull rod and the main clamping seat. The first clamping opening is formed between the movable clamp and the fixed clamp of the first clamping assembly, and the second clamping opening is formed between the movable clamp and the fixed clamp of the second clamping assembly.

[0013] Preferably, the present invention further includes a linkage rod, wherein the pull rod of the second clamping assembly and the pull rod of the first clamping assembly are hinged together via the linkage rod.

[0014] Preferably, the first mounting bracket is disposed between the fixed chuck of the first clamping assembly and the main body clamp seat; the second mounting bracket is disposed between the fixed chuck of the second clamping assembly and the main body clamp seat.

[0015] Preferably, the main clamp seat is composed of a base plate and side plates arranged on the left and right sides of the base plate. A storage space is formed between the two side plates for storing and installing the movable clamp, pull rod, and connecting rod. The base plate is also provided with a clearance notch for the movable clamp to move in and out.

[0016] The beneficial effects of this utility model are as follows: By arranging the first clamping component and the second clamping component in a stacked and spaced manner, and with the first clamping opening and the second clamping opening arranged in parallel and spaced manner, the two sides of the tubular profile can be clamped and fixed respectively. After the tubular profile is lifted, the balance of the tubular profile can be better controlled to provide stable support and prevent it from tilting to the side. This prevents the clamped part of the profile from bending and deforming, greatly reducing the probability of loosening or falling off, thereby greatly improving the stability and firmness of clamping and fixing the tubular profile.

[0022] like Figure 1 As shown, the double-layer clamping structure for clamping profiles according to this utility model includes a mounting base 1, a first clamping assembly 2 with a first clamping port 20, and a second clamping assembly 3 with a second clamping port 30. To achieve the purpose proposed by this utility model, as... Figure 3As shown, the first clamping component 2 and the second clamping component 3 are arranged in a stacked and spaced manner on the mounting base 1, and the first clamping port 20 and the second clamping port 30 are arranged in parallel and spaced apart. This utility model can clamp and fix both sides of the tubular profile respectively. After the tubular profile is lifted, it can better control the balance of the tubular profile to provide stable support, prevent it from tilting to the side, and prevent the clamped part of the profile from bending and deforming. This greatly reduces the probability of loosening or falling off, thereby greatly improving the stability and firmness of clamping and fixing the tubular profile.

[0023] To further improve the stability and firmness of profile clamping, such as Figure 1 As shown, there are multiple first clamping components 2, arranged horizontally at intervals. Similarly, there can also be multiple second clamping components 3, arranged horizontally at intervals. Preferably, there are two first clamping components 2 and one second clamping component 3, thus forming a three-headed clamp. This provides a stable and reliable triangular clamping support structure for the profile, ensuring that the profile will not swing or loosen after being clamped and lifted, greatly improving the reliability of use.

[0024] To further improve the structure of mounting base 1, such as Figure 4 As shown, the mounting base 1 includes a first mounting frame 11, a second mounting frame 12, and a connecting frame 13. The second mounting frame 12 is connected to the first mounting frame 11 via the connecting frame 13, and the second mounting frame 12 and the first mounting frame 11 are arranged in a stacked and spaced manner. The first clamping assembly 2 is disposed on the first mounting frame 11, and the second clamping assembly 3 is disposed on the second mounting frame 12. By providing the connecting frame 13, not only can the first mounting frame 11 and the second mounting frame 12 be connected together, but it is also easier to maintain the stacked and spaced state of the first mounting frame 11 and the second mounting frame 12, thereby maintaining the stacked and spaced state of the first clamping assembly 2 and the second clamping assembly 3.

[0025] For ease of assembly and disassembly, such as Figure 4As shown, this utility model also includes a locking bolt 14. The connecting frame 13 and the second mounting frame 12 are an integral structure, and the connecting frame 13 and the first mounting frame 11 are detachably fixed together by the locking bolt 14. With this detachable structural design, in practical applications, different lengths of the connecting frame 13 can be replaced according to the overall thickness of the profile, thus adapting to profiles of various thicknesses and providing wider compatibility. Furthermore, during manufacturing, only connecting frames 13 of various sizes need to be manufactured to assemble mounting seats 1 with various spacing sizes, which is very flexible and convenient, and can greatly reduce the manufacturing cost of the mounting seat 1. At the same time, by making the second mounting frame 12 and the connecting frame 13 an integral structure, the assembly steps of the mounting seat 1 can be greatly reduced, thereby improving assembly efficiency.

[0026] like Figure 1 As shown, the first mounting bracket 11 or the second mounting bracket 12 is also provided with fixing holes 15. Since the first mounting bracket 11 is a general-purpose component with fixed dimensions, it is preferable that the fixing holes 15 are provided on the first mounting bracket 11, so that there is no need to open fixing holes 15 on the second mounting bracket 12, thereby reducing the manufacturing difficulty of the second mounting bracket 12 and the connecting bracket 13. By providing fixing holes 15, the mounting base 1 and the lifting bracket can be easily fixedly connected together. When the profile undergoes surface treatment processes such as electroplating, electrophoresis, and anodizing, the lifting bracket and the double-layer clamp can be used to stably lift and immerse the profile into the electrolyte solution for surface treatment.

[0027] To further improve the structure of the first clamping component 2 and the second clamping component 3, such as Figure 2 and Figure 3As shown, the first clamping assembly 2 and the second clamping assembly 3 each include a main clamping seat 21, a movable clamp 22, a fixed clamp 23, a pull rod 24, a connecting rod 25, and a tension spring 26. The fixed clamp 23 is disposed on the main clamping seat 21. One end of the pull rod 24 and the movable clamp 22 are rotatably hinged to the main clamping seat 21, and the pull rod 24 drives the movable clamp 22 to move closer to or away from the fixed clamp 23 through the connecting rod 25. The two ends of the tension spring 26 are respectively connected to the pull rod 24 and the main clamping seat 21. The first clamping opening 20 is formed between the movable clamp 22 and the fixed clamp 23 of the first clamping assembly 2, and the second clamping opening 30 is formed between the movable clamp 22 and the fixed clamp 23 of the second clamping assembly 3. Specifically, the two ends of the connecting rod 25 are respectively hinged to the pull rod 24 and the movable clamp 22. Profile clamping process: By pulling the pull rod 24, the tension spring 26 is extended, and then the movable chuck 22 is pulled by the connecting rod 25, causing the movable chuck 22 to swing away from the fixed chuck 23, thereby opening the first clamping port 20 and the second clamping port 30 to facilitate the placement of the profile in the first clamping port 20 and the second clamping port 30; after the profile is placed in the first clamping port 20 and the second clamping port 30, by pulling the pull rod 24, the tension spring 26 retracts under the action of the rebound force, thereby pulling the pull rod 24 to move in the opposite direction, and then the movable chuck 22 is driven to approach the fixed chuck 23 by the connecting rod 25, thereby clamping the profile between the movable chuck 22 and the fixed chuck 23.

[0028] To make the operation simpler, such as Figure 2 As shown, this utility model also includes a linkage rod 4, through which the pull rod 24 of the second clamping component 3 and the pull rod 24 of the first clamping component 2 are hinged together. By setting the linkage rod 4, simply pulling the pull rod 24 of either the second clamping component 3 or the first clamping component 2 will cause both the pull rod 24 of the second clamping component 3 and the pull rod 24 of the first clamping component 2 to be pulled together, thus making the operation simpler.

[0029] To increase the adjustable range between the movable chuck 22 and the fixed chuck 23, such as Figure 3 As shown, the first mounting bracket 11 is disposed between the fixed clamp 23 and the main clamp seat 21 of the first clamping assembly 2; the second mounting bracket 12 is disposed between the fixed clamp 23 and the main clamp seat 21 of the second clamping assembly 3. This serves to raise the main clamp seat 21, thereby extending the distance between the main clamp seat 21 and the fixed clamp 23, thus increasing the adjustable range between the movable clamp 22 and the fixed clamp 23, and enabling the clamping of profiles with different wall thicknesses, thereby improving the applicability of the double-layer clamp structure.

[0030] To further improve the structure of the main clamp 21, such as Figure 5As shown, the main clamp seat 21 consists of a base plate 211 and side plates 212 disposed on the left and right sides of the base plate 211. A storage space 213 is formed between the two side plates 212 to accommodate the movable clamp 22, pull rod 24, and connecting rod 25. The base plate 211 also has a clearance notch 214 for the movable clamp 22 to move in and out. By providing the storage space 213, the movable clamp 22, pull rod 24, and connecting rod 25 are largely shielded, preventing external objects from obstructing their movement and making them more reliable. By providing the clearance notch 214, the movable clamp 22 is shielded without affecting its movement.

[0031] In practical applications, such as Figure 3 As shown, the main clamping seat 21 of the first clamping assembly 2 and the main clamping seat 21 of the second clamping assembly 3 are respectively provided with adjusting bolts 27, and one end of the tension spring 26 is connected to the adjusting bolt 27 of the main clamping seat 21. By setting the adjusting bolt 27, the distance between one end of the tension spring 26 and the main clamping seat 21 can be adjusted, thereby adjusting the magnitude of the elastic force of the tension spring 26 when the pull rod 24 is pulled, so as to prevent the clamping force on the profile from being too tight or too loose.
