Description

Technical Field

[0001] This application relates to the field of fitness equipment technology, and more specifically, to a single-point fixed tensioning structure. Background Technology

[0002] The support frame of fitness equipment is often made of square tubes. The ends of the square tubes have cuts, which need to be sealed with baffles to prevent the cuts from causing safety hazards and to increase the safety performance of the fitness equipment.

[0003] When installing existing baffles at the cut position, welding or bolting is often used. When welding, it is difficult to control the welding quality and the cost is high. When bolting is used, the bolts are often exposed on the side of the square tube, which affects the appearance of the product and also affects the safety of use.

[0004] In view of this, we propose a single-point fixed tensioning structure. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a single-point fixed tensioning structure to solve the problems mentioned in the background art.

[0007] 2. Technical Solution

[0008] This application is achieved through the following technical solution:

[0009] A single-point fixed tensioning structure includes a square tube with a notch at one end and a baffle at the notch. The bottom of the baffle has a first bend, the angle between the first bend and the baffle being smaller than the angle between the end face of the square tube and the horizontal plane. The first bend is capable of elastic deformation. A fixing hole is opened at the bottom of the square tube, and a bolt rod passes through the fixing hole. A threaded hole is opened on the first bend, and the bolt rod is threadedly connected to the threaded hole. The upper end of the baffle abuts against the upper end face of the square tube.

[0010] As an optional solution to the technical solution of this application, the baffle is provided with a second bending portion on both sides, and the second bending portion and the notch are inserted and matched in the vertical direction.

[0011] As an optional solution to the technical solution of this application, the baffle protrudes upwards through a second bend.

[0012] As an optional solution to the technical solution in this application, the baffle is chamfered at all four corners.

[0013] As an optional solution to the technical solution of this application, the connection between the baffle and the first bending part is arc-shaped, and the difference between the included angle between the first bending part and the baffle and the included angle between the end face of the square tube and the horizontal plane is 2°-3°.

[0014] As an optional solution to the technical solution in this application, a pad is fixedly connected to the bottom of the square tube.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] This application achieves bending of the first bend by setting a first bend at the bottom of the baffle and using bolts to pull the first bend downward, so that the baffle can cover the notch of the square tube and abut against the upper end face of the square tube. This effectively reduces the number of bolts used, increases installation efficiency, avoids the safety risks of exposed bolts, and makes the connection more aesthetically pleasing.

[0021] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0022] Please see Figure 1 and Figure 2 This application provides a single-point fixed tensioning structure, including a square tube 1. The end of the square tube 1 is provided with a notch 101, and a baffle 2 is provided at the notch 101. The bottom of the baffle 2 is provided with a first bending part 201. The included angle between the first bending part 201 and the baffle 2 is smaller than the included angle between the end face of the square tube 1 and the horizontal plane. The first bending part 201 can undergo elastic deformation. A fixing hole 102 is opened at the bottom of the square tube 1. A bolt rod 3 passes through the fixing hole 102. A threaded hole is opened on the first bending part 201. The bolt rod 3 is threadedly connected to the threaded hole. The upper end of the baffle 2 abuts against the upper end face of the square tube 1.

[0023] By inserting the bolt rod 3 into the fixing hole 102, covering the notch 101 with the baffle 2, and then screwing the bolt rod 3 into the threaded hole, the angle between the baffle 2 and the first bend 201 can be increased. This allows the baffle 2 to abut against the upper surface of the square tube 1, enabling it to be fixed with only one bolt rod 3. Since the bolt rod 3 is located at the bottom of the square tube 1, it is not exposed on the sides or top surface, increasing the safety of the square tube 1 during use and improving its aesthetics.

[0024] Preferably, the connection between the baffle 2 and the first bend 201 is an arc-shaped transition. The difference between the angle between the first bend 201 and the baffle 2 and the angle between the end face of the square tube 1 and the horizontal plane is 2°-3°. The baffle 2 has second bends 202 on both sides, which are vertically inserted into the notch 101. The baffle 2 protrudes upwards from the second bends 202, and chamfers are provided at all four corners. This design prevents the first bend 201 from being excessively bent, thus avoiding damage at the connection between the baffle 2 and the first bend 201. After the baffle 2 is installed, its upper end can abut against the upper surface of the square tube 1, limiting the bending range of the first bend 201 and increasing the coverage of the notch 101 by the baffle 2.

[0025] Preferably, a pad 103 is fixedly connected to the bottom of the square tube 1. The pad 103 can support the square tube 1 upward, so that there is a gap between the lower end of the bolt rod 3 and the bottom surface, which plays a role in protecting the bolt rod 3.
