Description

Technical Field

[0001] This utility model relates to the field of clamp technology, specifically a retractable toothed belt type I clamp. Background Technology

[0002] A clamp is a fastener used to fix or connect two materials. It is usually composed of components such as clamp plate, flange plate, tie plate and bolt, and is widely used in power, communication, pipeline engineering and other fields.

[0003] Existing clamps are all integral die-cast, with two clamps attached to the pipe surface and fixed to the pipe surface with bolts. Since the clamps cannot be extended or retracted to change the inner diameter, when the size is not suitable, clamps of different specifications must be replaced to fix the pipe. This makes the traditional clamps very limited in use. In order to solve the above problems, a telescopic toothed belt type I clamp is proposed. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a retractable toothed belt type I clamp.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a telescopic toothed belt type I clamp, including two first clamps and two second clamps, a connecting rod is fixedly installed on one side of the second clamp, a pre-embedded groove adapted to the connecting rod is opened on one side of the first clamp, a bracket is fixedly installed on one side of the top of the first clamp, and a limiting component is provided inside the bracket;

[0006] The limiting assembly includes a first toothed plate slidably connected to one side of the bracket. Support shafts are fixedly installed at the center of opposite sides inside the bracket. Gears are rotatably connected between the two support shafts. A second toothed plate is slidably connected to the other side of the bracket. A connecting plate is fixedly installed on one side of the bottom end of the second toothed plate. A limiting rod penetrating the bracket and the first clamp is fixedly installed at the center of the bottom end of the connecting plate. Several limiting grooves adapted to the limiting rod are opened on the surface of the connecting rod.

[0007] Preferably, a lever plate is fixedly installed on one side of the first toothed plate, and the surface of the lever plate is provided with protrusions.

[0008] Preferably, a horizontal plate is fixedly installed inside the bracket on the side near the gear, and a plurality of spring assemblies are fixedly installed at the bottom end of the horizontal plate, with the other end of the spring assembly connected to the connecting plate.

[0009] Preferably, connecting ears are fixedly installed on the other side of both first clamps and both second clamps, and bolts are installed on the radial inner wall of the connecting ears through internal and external thread engagement.

[0010] Preferably, a washer is fitted on the surface of the bolt, and several anti-slip strips are installed on the side of the washer facing the connecting lug.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The extension and retraction of the clamp can be achieved by sliding the connecting rod set on one side of the second clamp through the pre-embedded groove inside the first clamp. The clamp can be fixed after adjustment by the set limiting component, so that it can be adjusted in real time according to the specifications of the pipeline, which increases the practicality of the clamp.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-4As shown, this utility model provides a telescopic toothed belt type I clamp, including two first clamps 1 and two second clamps 2. The two first clamps 1 and two second clamps 2 can form a complete clamp. A connecting rod 5 is fixedly installed on one side of the second clamp 2. A pre-embedded groove 101 adapted to the connecting rod 5 is opened on one side of the first clamp 1. The connecting rod 5 can slide in the pre-embedded groove 101 inside the first clamp 1 to adjust the distance between the first clamp 1 and the second clamp 2. A bracket 6 is fixedly installed on one side of the top of the first clamp 1. A limiting component is provided inside the bracket 6. The limiting component limits and fixes the first clamp 1 and the second clamp 2 after adjustment.

[0021] The limiting component includes a first toothed plate 601 slidably connected to one side of the bracket 6. Support shafts 603 are fixedly installed at the center positions of opposite sides inside the bracket 6. A lever plate is fixedly installed on one side of the first toothed plate 601. The surface of the lever plate has protrusions. Moving the lever plate causes the first toothed plate 601 to move downwards inside the bracket 6. At this time, a gear 602 interacts with the first toothed plate 601 to rotate. A gear 602 is rotatably connected between the two support shafts 603. The rotating gear 602 interacts with a second toothed plate 604, causing the second toothed plate 604 to be limited along with the bottom end of the connecting plate 605. Moving the rod 606 upwards allows the first clamp 1 and the second clamp 2 to be adjusted by pulling the limiting rod 606 out of the limiting groove 501 on the surface of the connecting rod 5. Conversely, inserting the limiting rod 606 into the limiting groove 501 on the surface of the connecting rod 5 completes the limiting fixation. A second toothed plate 604 is slidably connected to the other side of the bracket 6. A connecting plate 605 is fixedly installed on one side of the bottom end of the second toothed plate 604. A limiting rod 606 that penetrates the bracket 6 and the first clamp 1 is fixedly installed at the center of the bottom end of the connecting plate 605. Several limiting grooves 501 that are adapted to the limiting rod 606 are opened on the surface of the connecting rod 5.

[0022] A horizontal plate 607 is fixedly installed inside the bracket 6 on one side near the gear 602. Several spring assemblies 608 are fixedly installed at the bottom of the horizontal plate 607. The other end of the spring assembly 608 is connected to the connecting plate 605.

[0023] By adopting the above technical solution, it is worth noting that when the first toothed plate 601 is moved down, the second toothed plate 604, along with the connecting plate 605, squeezes the spring assembly 608 under the action of the gear 602, thereby giving the spring assembly 608 elasticity. After the adjustment is completed, the lever is released and the spring assembly 608 elasticity causes the limiting rod 606 to pass through the bracket 6 and spring into the limiting groove 501 on the surface of the connecting rod 5.

[0024] Connecting ears 3 are fixedly installed on the other side of the two first clamps 1 and the two second clamps 2. Bolts 4 are installed on the radial inner wall of the connecting ears 3 through internal and external thread engagement. Washers are fitted on the surface of the bolts 4, and several anti-slip strips are installed on the side of the washers facing the connecting ears 3.

[0025] By adopting the above technical solution, the first clamp 1 and the second clamp 2 can be installed on the surface of the pipe by means of the connecting lug 3 and the bolt 4, and the friction between the bolt 4 and the connecting lug 3 can be increased by means of the gasket.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
