Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a horizontal bar. Background Art

[0002] A Chinese patent document with the publication number of CN216366446U discloses a telescopic horizontal bar, which is characterized by comprising a telescopic bar and two mounting seats for abutting against a support surface; the mounting seat includes a base and a sliding part for connecting the end of the telescopic bar; a concave cavity for the sliding part to slide up and down is arranged on the front side of the base; a first inclined surface is arranged in the concave cavity, and the inclination trend of the first inclined surface is gradually away from the support surface from top to bottom; an interface for connecting the end of the telescopic bar is arranged on the front side of the sliding part; a second inclined surface for sliding contact with the first inclined surface is arranged on the rear side of the sliding part; by applying a downward acting force to the telescopic bar, the sliding part moves downward, so that the second inclined surface of the sliding part presses the first inclined surface of the base, thereby making the base closely abut against the support surface.

[0003] In the above scheme during use, by applying a downward acting force to the telescopic bar, the sliding part connected to the telescopic bar moves downward, which causes the second inclined surface on the sliding part to press the first inclined surface of the base, and makes the base closely abut and press the support surface of the door frame. When the use time is long or the user overuses it, it is easy to cause the base to be unstable or slip. Therefore, there is still a large room for improvement in this telescopic horizontal bar. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a horizontal bar with reasonable structure, better stability and safety.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A horizontal bar includes a horizontal bar body and fixing mechanisms arranged at both ends of the horizontal bar body. The horizontal bar body is supported on an installation surface through the fixing mechanisms. It is characterized in that: the fixing mechanism includes a main support seat, a sub-support seat and a sliding seat. A main support surface that can fit with the installation surface is arranged at the front end of the main support seat. The front end of the sliding seat is movably arranged up and down at the rear end of the main support seat. The horizontal bar body is connected to the rear end of the sliding seat. The sub-support seat is movably arranged up and down on the main support seat. The sub-support seat is provided with a sub-support surface that can fit with the installation surface. The main support seat is provided with a first inclined surface. The sliding seat is provided with a second inclined surface that fits with the first inclined surface. The sub-support seat is provided with a third inclined surface. The sliding seat is provided with a fourth inclined surface that fits with the third inclined surface. The first inclined surface, the second inclined surface, the third inclined surface and the fourth inclined surface are inclined backward from top to bottom.

[0007] By adopting the above scheme, after the horizontal bar is tightly fixed on two opposite mounting surfaces, when the horizontal bar body is subjected to a downward force, the first inclined surface and the second inclined surface cooperate to apply a force toward the mounting surface to the main support seat, and the third inclined surface and the fourth inclined surface cooperate to apply a force toward the mounting surface to the auxiliary support seat, so that the horizontal bar can be firmly fixed on the two opposite mounting surfaces; when the horizontal bar body loosens and causes the main support seat and the sliding seat to slide downward, the auxiliary support seat will not slide downward with the main support seat and the sliding seat, and the third inclined surface and the fourth inclined surface cooperate to apply a force toward the mounting surface to the auxiliary support seat, so that the auxiliary support seat can also play the role of supporting the horizontal bar body, further increasing the stability and safety of the horizontal bar when in use, and the horizontal bar will not fall due to the loosening of the horizontal bar body.

[0008] The auxiliary support seat comprises a mounting portion and at least one fixing portion. The mounting portion is movably arranged between the main support seat and the slide seat. The fixing portion is connected to the mounting portion. The front end of the fixing portion is provided with the auxiliary support surface.

[0009] By adopting the above scheme, the mounting part is movably arranged up and down between the main support seat and the slide seat, which can facilitate the use of the horizontal bar. Through the mounting part, the auxiliary support seat and the main support seat can be supported together on the support surface to increase the stability of the horizontal bar when in use.

[0010] The auxiliary support seat includes two fixing parts which are symmetrically arranged on both sides of the mounting part.

[0011] By adopting the above solution, two fixing parts are symmetrically arranged on both sides of the mounting part, so that the contact area between the auxiliary support seat and the mounting surface can be increased to increase the stability of the auxiliary support seat.

[0012] A first spring is arranged between the mounting portion and the main support seat, and the first spring is used to drive the auxiliary support seat to move downward.

[0013] By adopting the above solution, a first spring is arranged between the mounting portion and the main support seat, and the first spring can drive the auxiliary support seat to move downward to prevent the auxiliary support seat from being separated from the main support seat.

[0014] A limiting groove is arranged on the front end surface of the mounting portion, and a limiting portion located in the limiting groove is arranged at the rear end of the main supporting seat, and the limiting portion can move up and down in the limiting groove.

[0015] By adopting the above scheme, a limit groove is set on the front end surface of the mounting part, and a limit part located in the limit groove is set at the rear end of the main support seat, so that the limit part can move up and down in the limit groove. In this way, the movement of the limit part can be limited by the limit groove to prevent the mounting part from leaving the sliding range when in use.

[0016] A third spring is arranged between the slide seat and the mounting portion, and the third spring can apply a pre-tightening force to the mounting portion toward the mounting surface.

[0017] By adopting the above - mentioned solution, the third spring can apply a pre - tightening force towards the mounting surface to the mounting part, which is convenient for the installation of the horizontal bar. Specifically, when the horizontal bar has not been fully tightened against the mounting surface, the pre - tightening of the auxiliary support seat against the mounting surface can facilitate the operation of the horizontal bar body, extend the horizontal bar body, and finally make the horizontal bar fully tightened against the mounting surface; and when the horizontal bar body is slightly loose, the pre - tightening force can also ensure that the horizontal bar does not fall. In this state, if the horizontal bar is used continuously, under the cooperation of the third inclined surface and the fourth inclined surface, a force towards the mounting surface will be applied to the auxiliary support seat, enabling the auxiliary support seat to also play a role in supporting the horizontal bar body.

[0018] A second spring is arranged between the main support seat and the sliding seat, and this second spring is used to drive the sliding seat to move upward.

[0019] By adopting the above - mentioned solution, using the second spring to drive the sliding seat to move upward can reduce the acting force of the sliding seat on the main support seat, which is convenient for adjusting the position of the main support seat on the mounting surface.

[0020] An installation groove is arranged at the rear end of the main support seat, and a protruding convex part is arranged at the front end of the sliding seat. The convex part is movably arranged up and down in the installation groove. The bottom of the installation groove constitutes the first inclined surface, and the front end surface of the convex part constitutes the second inclined surface.

[0021] By adopting the above - mentioned solution, arranging the convex part movably up and down in the installation groove can prevent the sliding seat from shifting or detaching from the main support seat during use, and through the mutual cooperation of the first inclined surface formed by the bottom of the installation groove and the second inclined surface formed by the front end surface of the convex part, the main support seat can be tightened against the mounting surface.

[0022] A long - shaped limiting hole is formed on the bottom of the installation groove, a limiting column that can pass through the long - shaped limiting hole is formed at the front end of the convex part, and a locking part for preventing the limiting column from detaching from the long - shaped limiting hole is arranged on the limiting column.

[0023] By adopting the above - mentioned solution, passing the limiting column formed at the front end of the convex part through the long - shaped limiting hole, the long - shaped limiting hole can facilitate the up - and - down movement of the sliding seat, and the cooperation between the limiting column and the locking part further fixes the sliding seat on the main support seat.

[0024] The first inclined surface and the third inclined surface are arranged parallel to each other, and the second inclined surface and the fourth inclined surface are arranged parallel to each other.

[0025] By adopting the above - mentioned solution, making the first inclined surface and the third inclined surface parallel to each other, and the second inclined surface and the fourth inclined surface parallel to each other, can make the cooperation between the first inclined surface and the second inclined surface closer, and the cooperation between the third inclined surface and the fourth inclined surface closer.

[0026] Elastic buffer pads are provided on both the main support surface and the secondary support surface.

[0027] By adopting the above solution, the friction between the main support surface and the secondary support surface can be increased, making the main support surface and the secondary support surface more stable during use. Description of the Drawings

[0035] Referring to Figures 1 to 7 Shown in one kind, the technical solution of the present utility model will be further described below through specific embodiments in conjunction with the accompanying drawings of the specification:

[0036] A horizontal bar includes a horizontal bar body 1 and a fixing mechanism 2 provided at both ends of the horizontal bar body 1. The horizontal bar body 1 is supported on the installation surface through the fixing mechanism 2.

[0037] The horizontal bar body 1 is a telescopic tubular structure, and its specific structure is the prior art and will not be described in detail here. A timing or counting device 11 can also be installed in the middle of the horizontal bar body 1 to enable the user to directly record the training process and data. The falling of the horizontal bar is often caused by the loosening of the horizontal bar body 1. Here, the loosening refers to that the telescopic horizontal bar body 1 is not installed in place, that is, it is not fully tightened, or the locking member on the horizontal bar body 1 is not fully locked after tightening, resulting in the loosening and sliding down of the horizontal bar body 1 under force.

[0038] The fixing mechanism 2 includes a main support base 21, a secondary support base 22 and a sliding base 23. The front end of the sliding base 23 is movably arranged up and down at the rear end of the main support base 21. The secondary support base 22 is movably arranged up and down on the main support base 21. The main support base 21 is provided with a first inclined surface 211. The sliding base 23 is provided with a second inclined surface 231 that fits with the first inclined surface 211. The secondary support base 22 is provided with a third inclined surface 221. The sliding base 23 is provided with a fourth inclined surface 232 that fits with the third inclined surface 221. When a downward force is applied to the horizontal bar body 1, the first inclined surface 211 slides downward and cooperates with the second inclined surface 231 to apply a force towards the installation surface to the main support base 21. The third inclined surface 221 slides downward and cooperates with the fourth inclined surface 232 to apply a force towards the installation surface to the secondary support base 22.

[0039] The front end of the main support base 21 is provided with a main support surface 212 that can fit with the installation surface. The main support surface 212 fits with the installation surface through an elastic buffer pad 24. This can increase the friction between the main support surface 212 and the installation surface, making the main support base 21 more stably supported on the installation surface. The secondary support base 22 includes an installation part 222 and two fixing parts 223. The installation part 222 and the two fixing parts 223 are integrally formed. The two fixing parts 223 are located on both sides of the installation part 222. The front end of the fixing part 223 is provided with a secondary support surface 224. The secondary support surface 224 is also provided with an elastic buffer pad 24 to increase the friction between the secondary support surface 224 and the installation surface. The installation part 222 is movably arranged up and down between the main support base 21 and the sliding base 23. A first spring 25 is arranged between the installation part 222 and the main support base 21. The first spring 25 is used to drive the secondary support base 22 to move downward. The front end surface of the installation part 222 is provided with a limit groove 225. The rear end of the main support base 21 is provided with a limit part 213 located in the limit groove 225. The limit part 213 can move up and down in the limit groove 225. A third spring 27 is arranged between the sliding base 23 and the installation part 222. The third spring 27 can apply a pre-tightening force towards the installation surface to the installation part 222, which is convenient for the installation of the horizontal bar. Specifically, when the horizontal bar is not fully tightened against the installation surface, through the pre-tightening of the secondary support base 22 against the installation surface, it is convenient to operate the horizontal bar body 1, extend the horizontal bar body 1, and finally make the horizontal bar fully tightened against the installation surface. And when the horizontal bar body 1 is slightly loose, this pre-tightening force can also ensure that the horizontal bar does not fall off. In this state, if the horizontal bar is continued to be used, under the cooperation of the third inclined surface 221 and the fourth inclined surface 232, a force towards the installation surface will be applied to the secondary support base 22, enabling the secondary support base 22 to also play a role in supporting the horizontal bar body 1.

[0040] A second spring 26 is provided between the main support base 21 and the sliding seat 23. The second spring 26 is used to drive the sliding seat 23 to move upward. An installation groove 214 is provided at the rear end of the main support base 21. A protruding convex portion 233 is provided at the front end of the sliding seat 23. The convex portion 233 is movably arranged up and down in the installation groove 214. The bottom of the installation groove 214 constitutes a first inclined surface 211. The front end surface of the convex portion 233 constitutes a second inclined surface 231. A long-shaped limiting hole 215 is further formed on the bottom of the installation groove 214. A limiting post 234 that can pass through the long-shaped limiting hole 215 is formed at the front end of the convex portion 233. A locking member 235 for preventing the limiting post 234 from detaching from the long-shaped limiting hole 215 is provided on the limiting post 234. A positioning groove 236 is formed at the rear end of the sliding seat 23. A limiting protrusion 237 is formed on the inner wall of the groove. A groove adapted to the limiting protrusion 237 is formed on the horizontal bar body 1. The cooperation between the limiting protrusion 237 and the groove can prevent the horizontal bar body 1 from rotating during use.

[0041] During installation, as shown in Figures 1 to 5 , the horizontal bar main body 1 can be first supported on the installation surface through the fixing mechanism 2. At this time, the first spring 25 drives the auxiliary support base 22 to move downward, so that the auxiliary support base 22 is fixed on the main support base 21. The second spring 26 drives the sliding seat 23 to slide upward, so that the convex portion 233 slides upward to the upper groove wall of the installation groove 214. The third spring 27 drives the installation portion 222 to apply a pre-tightening force towards the installation surface. At this time, the user can conveniently adjust the installation position of the fixing mechanism 2.

[0042] During use, as shown in Figures 6 to 7 , when the user applies a downward force to the horizontal bar main body 1, the horizontal bar main body 1 drives the sliding seat 23 to slide downward, so that the first inclined surface 211 and the second inclined surface 231 cooperate, and the third inclined surface 221 and the fourth inclined surface 232 cooperate to convert the downward force into the supporting force of the fixing mechanism 2 on the installation surface. When the sliding seat 23 slides downward, the first spring 25 and the third spring 27 are compressed. Driven by the third spring 27, the auxiliary support base 22 further abuts against the installation surface. When the convex portion 233 slides to the bottom wall of the installation groove 214, the sliding seat 23 will drive the main support base 21 to slide downward. The auxiliary support base 22 and the main support base 21 are slidably connected. Therefore, when the sliding seat 23 drives the main support base 21 to slide downward, the first spring 25 and the third spring 27 will be triggered to make the auxiliary support base 22 press tightly against the installation surface and further support the main support base 21 and the sliding seat 23. In this way, even when the sliding seat 23 and the main support base 21 slide downward, the auxiliary support base 22 can also play a good supporting role and further improve the stability of the fixing mechanism 2, so that the user can perform pull-up training on the horizontal bar main body 1 more stably and safely.

[0043] The above are only the preferred embodiments of the present utility model, and thus the scope of implementation of the present utility model cannot be limited thereby. That is, equivalent changes and modifications made in accordance with the scope of the patent application of the present utility model and the content of the specification should still fall within the scope covered by the patent of the present utility model.
