Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically a locking structure for a fitness horizontal bar. Background Technology

[0002] The current door-mounted exercise bar allows users to rotate the threaded end tubes connected to both ends of the main tube to extend outwards and push against the door walls on both sides. When the user performs pull-ups while holding the main tube, a torsional force is applied to the main tube. If the direction of the torsion is opposite to the original direction of the torsion to extend the end tube, the end tube may retract towards the main tube, causing the user to fall off the bar and causing a safety problem.

[0003] Publication No. CN215916334U discloses a single-bar locking structure for a door, including a grab bar with telescopic rods on both sides. The grab bar has a first threaded portion, and the telescopic rods have a second threaded portion that mates with the first threaded portion. The outer contour of the grab bar's cross-section is a regular polygon. A connecting sleeve is slidably mounted on the telescopic rod, and the connecting sleeve has a connecting hole that mates with the end of the grab bar. The connecting hole mates with the grab bar and restricts the relative rotation between the grab bar and the telescopic rod. The telescopic rod has a sliding groove, and the connecting sleeve has a guide protrusion that matches the sliding groove.

[0004] The aforementioned patent provides a simple, easy-to-manufacture, and long-lasting door bar locking structure. It uses a connecting sleeve to prevent the mounting base from rotating relative to the telescopic bar during use. Although a component that can limit rotation is added to the connecting base, the connecting sleeve does not have a component that is fixed relative to the hand gripper. This allows the connecting sleeve to slide left and right. If the user moves too much during use and the connecting sleeve slips onto the telescopic bar, losing the locking effect between the telescopic bar and the hand gripper, the telescopic bar and the hand gripper will still slide, and the stability of the fixation cannot be guaranteed.

[0005] Based on this, a locking structure for a fitness horizontal bar is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a locking structure for a fitness horizontal bar to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A locking structure for a fitness horizontal bar includes a locking assembly for connecting an anti-slip seat and the horizontal bar body. There are two anti-slip seats arranged symmetrically. The horizontal bar body is located in the middle of the two anti-slip seats. A connecting pipe is fixedly connected to both ends of the horizontal bar body. Several limiting grooves are arrayed on the surface of the connecting pipe.

[0009] The locking assembly includes a locking sleeve, with a limiting tube threadedly connected to the inner side of the locking sleeve. The limiting tube is slidably connected to one end of an adjacent connecting tube, and a limiting assembly is provided in the middle of the limiting tube.

[0010] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0011] In one alternative: the limiting component includes a through groove, which is opened through the middle of the limiting tube. Two limiting blocks are slidably disposed in the through groove. The two limiting blocks are symmetrically arranged and their adjacent ends are limited and connected to the upper and lower sides of the corresponding limiting groove.

[0012] In one alternative: a telescopic support rod is fixed to the middle of one end of the anti-slip seat near the connecting pipe, and the other end of the telescopic support rod is slidably connected to one end of the adjacent connecting pipe.

[0013] In one alternative: the locking sleeve extends through the outside of the connecting tube, and one side of the locking sleeve is provided with a connecting component for connecting with the anti-slip seat.

[0014] In one alternative: the connecting component includes a fixing groove, which is formed at one end of the locking sleeve near the anti-slip seat, and a fixing ring is slidably connected inside the fixing groove.

[0015] In one alternative: a second threaded hole is provided through the middle of the upper end of the fixing ring, and a first threaded hole is provided correspondingly at the end of the locking sleeve near the anti-slip seat.

[0016] In one alternative: the first threaded hole and the second threaded hole are fixed by a locking bolt threaded connection.

[0017] In one alternative: the anti-slip seat is provided with an anti-slip pad at the end away from the horizontal bar body.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model uses a locking component that employs a snap-fit ​​method for fixation, abandoning the conventional threaded connection method. This ensures that the locking effect is not affected when the bar body rotates, effectively improving the safety of the bar. At the same time, the multiple limit grooves provide length adjustment for the device, ensuring that it can be used with doors of different sizes, effectively improving the device's usability and enhancing user protection.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, a locking structure for a fitness bar includes a locking assembly for connecting an anti-slip seat 1 and a bar body 2. There are two anti-slip seats 1 arranged symmetrically. The bar body 2 is located in the middle of the two anti-slip seats 1. A connecting pipe 3 is fixedly connected to both ends of the bar body 2. Several limiting grooves 9 are arrayed on the surface of the connecting pipe 3.

[0027] The locking assembly includes a locking sleeve 7, with a limiting tube 4 threadedly connected to the inner side of the locking sleeve 7. The limiting tube 4 is slidably connected to one end of an adjacent connecting tube 3, and a limiting assembly is provided in the middle of the limiting tube 4.

[0028] In this embodiment, the connecting pipes 3 at both ends are locked to the anti-slip seat 1 by the locking assembly. The limiting groove 9 on the connecting pipe 3 can be used to adjust the length of the entire bar to adapt to different door sizes.

[0029] In one embodiment, such as Figure 2 As shown, in one optional embodiment: the limiting component includes a through groove 5, which is opened through the middle of the limiting tube 4. Two limiting blocks 6 are slidably arranged in the through groove 5. The two limiting blocks 6 are symmetrically arranged and their adjacent ends are limited and connected to the upper and lower sides of the corresponding limiting groove 9. After adjusting the position of the connecting tube 3 inside the limiting tube 4 according to the size of the door, the limiting block 6 is placed through the through groove 5. At this time, one end of the limiting block 6 is limited by the corresponding limiting groove 9. Then, the locking sleeve 7 is rotated and tightened to complete the initial fixation.

[0030] In one embodiment, such as Figure 2As shown, a telescopic support rod 8 is fixed at the middle of one end of the anti-slip seat 1 near the connecting pipe 3. The other end of the telescopic support rod 8 is slidably connected to one end of the adjacent connecting pipe 3. The telescopic support rod 8 passes through the connecting pipe 3 to improve the overall load-bearing capacity of the bar and prevent breakage at the locking component position.

[0031] In one embodiment, such as Figure 2 As shown, the locking sleeve 7 is disposed through the outside of the connecting tube 3. A connecting component for connecting with the anti-slip seat 1 is provided on one side of the locking sleeve 7. The locking sleeve 7 is fixed on the anti-slip seat 1 by the connecting component to prevent the locking sleeve 7 from becoming loose.

[0032] In one embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the connecting assembly includes a fixing groove 14, which is located at one end of the locking sleeve 7 near the anti-slip seat 1.

[0034] In one embodiment, such as Figure 2 As shown, the first threaded hole 10 and the second threaded hole 13 are fixed by a locking bolt 11. The locking bolt 11 passes through the first threaded hole 10 and the second threaded hole 13 to fix the fixing ring 12 and the locking sleeve 7, thus completing the fixing effect between the locking sleeve 7 and the anti-slip seat 1.

[0035] In one embodiment, such as Figure 1 As shown, the anti-slip seat 1 has an anti-slip pad at the end away from the horizontal bar body 2, which improves the anti-slip ability of the horizontal bar on the door.

[0036] The above embodiment discloses a locking structure for a fitness bar. In use, the position of the connecting tube 3 inside the limiting tube 4 is adjusted according to the actual situation. Then, the two limiting blocks 6 are slidably placed into the through groove 5 from the upper and lower sides respectively. At this time, one end of the limiting block 6 slides and fits against the inner side of the corresponding limiting groove 9. Then, the locking sleeve 7 is threadedly connected to the limiting tube 4. At this time, the fixing ring 12 slides and is limited into the inside of the fixing groove 14. Finally, the locking bolt 11 passes through the first threaded hole 10 and the second threaded hole 13 and is threadedly connected to it to fix the locking sleeve 7 to the anti-slip seat 1, thus completing the installation.
