AI Technical Summary
The existing three-way interconnection structure increases the length of the support rod during installation due to bolt interference, which reduces the adjustment range of the fitness equipment.
By setting notches at the connection points of the support rods and connecting the first and second crossbars at the same height using the first and second bolt rods, bolt interference is avoided, and the adjustment range of the fitness equipment is increased.
This allows for a greater range of adjustment on the support rod of the fitness equipment, meeting users' needs for the height of the cable output end.

Abstract
Description
Technical Field
[0001] This application relates to the field of fitness equipment technology, and more specifically, to a three-way interconnection structure. Background Technology
[0002] As people's living standards improve, gym equipment is increasingly entering homes. The height of a home after renovation also influences the height of the equipment consumers purchase. When performing exercises (such as flyes (for lower chest exercises), lat pulldowns, and assisted pull-ups), adjusting the rack height (the height of the cable output end) allows users to complete the entire exercise, maximizing the stimulation of the targeted muscles and achieving optimal fitness goals.
[0003] like Figure 3 As shown, Figure 3 The three-way interconnection structure in the middle connects two crossbars horizontally to the upper end of the support rod with bolts. In order to avoid interference between the bolts, they need to be staggered in the height direction, which increases the length of the support rod occupied by the two crossbars during installation and reduces the adjustable range of the fitness equipment on the support rod.
[0004] In view of this, we propose a three-way interconnection structure. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] The purpose of this application is to provide a three-way interconnect 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 three-way interconnection structure includes a support rod, with a first crossbar and a second crossbar connected to the upper part of the support rod. The support rod is hollow and has a connecting part at its upper end. A notch is provided on one side of the connecting part. A first mounting hole is formed along the length of the first crossbar, and a second mounting hole is formed along the width of the first crossbar. The end of the first crossbar is inserted into the connecting part through the notch. A first threaded hole is formed along the length of the first crossbar, and a third mounting hole is formed along the width of the first crossbar. A second threaded hole is formed along the length of the second crossbar. A first bolt is threaded through the first mounting hole and connected to the first threaded hole. A second bolt is threaded through the second mounting hole and slides through the third mounting hole, connecting to the second threaded hole.
[0010] As an optional solution to the technical solution of this application, the support rod, the first crossbar and the second crossbar are all hollow square tubes.
[0011] As an optional solution to the technical solution of this application, the first mounting hole, the second mounting hole, the first threaded hole, the third mounting hole, and the second threaded hole are each provided in two along the vertical direction.
[0012] As an optional solution to the technical solution of this application, the first mounting hole and the second mounting hole are opened at the same height.
[0013] As an optional solution to the technical solution in this application, the length of the first bolt rod is less than the distance from the third mounting hole to the end face of the first crossbar.
[0014] As an optional solution to the technical solution in this application, the support rod is provided with multiple adjustment holes.
[0015] As an optional solution to the technical solution in this application, a pulley mounting bracket is fixed to the outer side of the first crossbar.
[0016] As an optional solution to the technical solution of this application, the upper part of the support rod is provided with a pulley mounting groove, which is located below the notch.
[0017] 3. Beneficial effects
[0018] Compared with the prior art, the beneficial effects of this application are:
[0019] This application provides a notch in the connecting part of the support rod, allowing the end of the first crossbar to be inserted into the connecting part. A second bolt rod can then pass through the first crossbar and connect to the second crossbar, ensuring that the first and second bolt rods are at the same height. This avoids excessive occupation of the support rod's length, increases the adjustable range of the fitness equipment at the bottom of the support rod, and allows the output end of the steel cable passing through the pulley mounting groove to be positioned higher, meeting the user's needs.

[0024] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.
[0025] Please see Figure 1 and Figure 2 This application provides a technical solution:
[0026] A three-way interconnection structure includes a support rod 1, with a first crossbar 2 and a second crossbar 3 connected to the upper part of the support rod 1. Preferably, the support rod 1, the first crossbar 2 and the second crossbar 3 are all hollow square tubes.
[0027] The upper end of the support rod 1 is provided with a connecting part 101, and a notch 102 is provided on one side of the connecting part 101. The connecting part 101 has a first mounting hole 103 along the length direction of the first crossbar 2 and a second mounting hole 104 along the width direction of the first crossbar 2. The first mounting hole 103 and the second mounting hole 104 are opened at the same height. The end of the first crossbar 2 is inserted into the connecting part 101 through the notch 102. The end of the first crossbar 2 has a first threaded hole 201 along its length direction and a third mounting hole 202 along its width direction. The end of the second crossbar 3 has a second threaded hole 301 along its length direction. A first bolt rod 4 passes through the first mounting hole 103. The length of the first bolt rod 4 is less than the distance from the third mounting hole 202 to the end face of the first crossbar 2. The first bolt rod 4 is threadedly connected to the first threaded hole 201. A second bolt rod 5 passes through the second mounting hole 104. The second bolt rod 5 slides through the third mounting hole 202 and is threadedly connected to the second threaded hole 301.
[0028] When installing the support rod 1, the first crossbar 2, and the second crossbar 3, firstly, the end of the first crossbar 2 is inserted into the connecting part 101 through the notch 102. Then, the first bolt 4 passes through the first mounting hole 103 and is screwed into the first threaded hole 201 to fix the end of the first crossbar 2. Next, the second threaded hole 301 at the end of the second crossbar 3 is aligned with the second mounting hole 104 on the side of the connecting part 101. The second bolt 5 passes through the second mounting hole 104 and the third mounting hole 202 and is screwed into the second threaded hole 301 to fix the end of the second crossbar 3. By adopting this connection structure, the first bolt 4 used to fix the first crossbar 2 and the second bolt 5 used to fix the second crossbar 3 can be placed at the same height without interference, reducing the length occupied by the first crossbar 2 and the second crossbar 3 on the support rod 1, and providing a wider range for height adjustment of the fitness equipment on the support rod 1.
[0029] Preferably, the first mounting hole 103, the second mounting hole 104, the first threaded hole 201, the third mounting hole 202, and the second threaded hole 301 are each provided in two in the vertical direction to increase the stability of the first crossbar 2 and the second crossbar 3 on the support rod 1.
[0030] Preferably, the support rod 1 has multiple adjustment holes 105, and the outer side of the first crossbar 2 is fixed with a pulley mounting bracket 203, so that the user can install the fitness equipment onto the support rod 1 and the first crossbar 2.
[0031] Preferably, the upper part of the support rod 1 is provided with a pulley mounting groove, which is located below the notch 102. The user can install the fixed pulley in the pulley mounting groove with bolts, and the output end of the steel cable can bypass the fixed pulley and be kept in a higher position. This avoids the connection between the support rod 1, the first crossbar 2 and the second crossbar 3 occupying too much space on the support rod 1, which would cause the height of the output end of the steel cable to fail to meet the usage requirements.
