Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to an indoor horizontal bar support arm structure. Background Art

[0002] As people's living standards improve, they pay more and more attention to healthy living. However, modern people work long hours and have a fast pace of life, so the time for outdoor exercise is gradually decreasing, and they exercise more indoors. Now there are many indoor fitness equipment on the market, such as horizontal bars that can exercise arm strength. Therefore, indoor horizontal bars, as a kind of fitness equipment that is convenient to use indoors and easy to install, can easily meet people's fitness needs for pull-ups. In order to improve safety, a Chinese utility model patent with authorization announcement number CN220237654U has been published, which discloses an indoor horizontal bar with a more secure installation, including a main body, telescopic rods that can move along the axial direction are inserted at both ends of the main body, and support components are arranged at the ends of the telescopic rods. The support component includes a mounting seat and a sliding seat, and a sloped protrusion is formed on the side where the sliding seat is connected to the mounting seat, and a supporting slope is formed on the mounting seat, and the supporting slope is wedge-shaped with a small top and a large bottom; the support component also includes an anti-slip part, the upper end of the anti-slip part is rotatably connected to the sliding seat through a first rotating shaft, and the middle part of the anti-slip part is rotatably connected to the mounting seat through a second rotating shaft, and an abutment part is formed on one side of the anti-slip part. When the sliding seat moves downward relative to the mounting seat, the anti-slip part The anti-skid member is linked to and increases the friction force of the abutment against the wall. However, this can achieve dual anti-skid and anti-detachment functions through the mounting seat and the anti-skid member. However, since the mounting seat and the sliding seat need to cooperate through the inclined surface to achieve that the mounting seat can be stably fixed on the wall / door frame, etc., this will increase the difficulty of production and increase the production cost. Secondly, since the main body, the telescopic rods at both ends of the main body and the end of the telescopic rod are required to be provided with a support assembly, the support assembly includes a mounting seat and a sliding seat, and the upper end of the anti-skid member is rotatably connected to the sliding seat through a first rotating shaft. It can be seen that there are many such components, which invisibly increases the production cost and is not conducive to mass production of manufacturing enterprises. Therefore, improvements are urgently needed for this situation. Utility Model Content

However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0033] Example 1: See Figure 1 , an indoor horizontal bar support arm structure, comprising a single-rod body 1, main support arms 2 are arranged at both ends of the single-rod body 1, a fixing assembly 3 for axial locking is arranged between the single-rod body 1 and the main support arm 2, one end face of the main support arm 2 is movably connected with a main mounting seat 4, the other end of the main support arm 2 is movably connected with a secondary support arm 5, the secondary support arm 5 is movably connected with a secondary mounting seat 6, and the lever movement is realized by taking the other end of the main support arm 2 and the secondary support arm 5 as a fulcrum, and the single-rod body 1 moves up and down on the main support arm 2 so that the secondary support arm 5 can make a lever movement with the other end of the main support arm 2 and the secondary support arm 5 as a fulcrum, so that the secondary support arm 5 can move through the secondary mounting seat The seat 6 applies additional pressure toward the wall or door frame to generate greater friction, so that during use, each time the user exerts force to move the single-rod body 1 downward, the single-rod body 1 will prompt the secondary support arm 5 to make a lever movement, and then the secondary support arm 5 will be tightly pressed against the wall or door frame through the secondary mounting seat 6, ultimately making it able to press against the wall or door frame more and more during use, making it safer and more reliable to use. In addition, since the utility model can achieve dual orientation towards the wall or door frame through the combination of the main support arm 2 and the secondary support arm 5, its design is more reasonable, which greatly reduces the difficulty and burden of the manufacturing enterprise and is more suitable for the enterprise's mass production.

[0034] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9As shown, the main support arm 2 includes an arm body 21, and the arm body 21 is provided with a distance adjustment hole 22 for adjusting the single-rod body 1 up and down. The single-rod body 1 and the arm body 21 are axially locked by a fixing assembly 3, which is helpful to prevent the axial movement of the single-rod body 1. One end of the arm body 21 is movably connected to a main mounting seat 4, and the other end of the arm body 21 is movably connected to a secondary support arm 5. A mounting hole 23 is provided at the other end of the arm body 21, and the secondary support arm 5 extends into the mounting hole 23 and extends to a position below the single-rod body 1. When the single-rod body 1 moves downward, the single-rod body 1 will prompt the secondary support arm 5 to make a lever movement.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 As shown, it is to be noted that the distance adjustment hole 22 is a court hole, wherein the court hole is rectangular in the middle and semicircular at both ends. This arrangement is conducive to realizing the up and down movement of the single-rod body 1, thereby achieving the effect that the single-rod body 1 can be adjusted up and down.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 As shown, it should be noted that the arm body 21 is connected to the main mounting seat 4 via a movable shaft (not shown in the figure), which is conducive to realizing that one end surface of the main support arm 2 is movably connected to the main mounting seat 4.

[0037] Embodiment 3: It can be explained on the basis of embodiment 2, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the fixing assembly 3 includes a threaded portion 31 disposed on both ends of the single-rod body 1, and an outer nut 32 and an inner nut 33 are disposed on the single-rod body 1 of the threaded portion 31, and the arm body 21 is located on the single-rod body 1 of the threaded portion 31 between the outer nut 32 and the inner nut 33, which is conducive to locking the single-rod body 1 in the axial direction. Among them, the inner nut 33 includes a sleeve 331, and a shaft body 332 is disposed on the sleeve 331. One end of the sleeve 331 can be inserted into the distance adjustment hole 22, which is conducive to preventing the single-rod body 1 from moving axially.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it is to be explained that the auxiliary support arm 5 includes a main body 51 and an arc groove 52 arranged on one end face of the main body 51 and matched with the single-rod main body 1. One end of the main body 51 extends into a position below the single-rod main body 1 in the main support arm 2, and the main body 51 is movably connected to the main support arm 2 through a rotating shaft 53. This arrangement is reasonable, simple in structure, and easy to implement.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it should be noted that the other end of the main body 51 is connected to the auxiliary mounting seat 6 via a rotating shaft (not shown in the figure), which is conducive to better pressing against the wall or door frame.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the two ends of the single-rod body 1 of the utility model respectively pass through the distance adjustment holes 22 on the corresponding arm body 21, and the distance is adjusted and tightened (to prevent axial movement) through the threaded parts 31 at both ends of the single-rod body 1 and the corresponding external nuts 32 and internal nuts 33. At this time, the end face of the secondary support arm 5 is tightly against the single-rod body 1 through the pressure adjusted by the internal nut 33 on the single-rod body 1, so that the main support arm 2 and the secondary support arm 5 as a whole are tightly against the wall or door frame. When in use, the single-rod body 1 is adjusted to an appropriate length, and then the main mounting seat 4 on the arm body 21 is tightly pressed against the wall or door frame. In actual use, since the single-rod body 1 moves downward due to weight, the single-rod body 1 presses down the secondary support arm 5. Through the lever principle, the secondary support arm 5 in the main support arm 2 uses the rotating shaft 53 as a fulcrum to apply downward pressure to the secondary support arm 5. Through the secondary support arm 5, the secondary mounting seat 6 on the secondary support arm 5 is tightly pressed against the wall or door frame, thereby achieving secondary pressing against the wall or door frame, which is more conducive to making the support more stable and safer.

[0041] Embodiment 4: It can be explained on the basis of embodiment 2, such as Figure 7 , Figure 8 and Fig. 9As shown, the fixing assembly 3 includes a rod 34 arranged at both ends of the single rod body 1, each rod 34 passes through the corresponding distance adjustment hole 22, and a sliding sleeve 35 is arranged on the rod 34 to move up and down along the arm body 21, and a jacket 36 is arranged on the rod 34, and the jacket 36 contacts the sliding sleeve 35, which is helpful to prevent the single rod body 1 from moving too far in the distance adjustment hole 22 of the arm body 21. When the lower end of the sliding sleeve 35 touches the auxiliary support arm 5 after moving downward, it drives the auxiliary support arm 5 to make a lever movement on the arm body 21, so that the auxiliary support arm 5 will be tightly pressed against the wall or door frame through the auxiliary mounting seat 6. In this embodiment, the auxiliary support arm 5 adopts an inclined plate, which is reasonable and easy to implement.

[0042] like Figure 7 , Figure 8 and Fig. 9 As shown, it is to be explained that the outer sleeve 36 and the rod portion 34 can be integrally formed, and the rod portion 34 and the single-rod body 1 can be integrally formed, which greatly improves the firmness of the structure.

[0043] like Figure 7 , Figure 8 and Fig. 9 As shown, it is also to be noted that the rod portion 34 is non-threaded. This arrangement is reasonable, simple in structure, and easy to implement.

[0044] like Figure 7 , Figure 8 and Fig. 9 As shown, the rods 34 at both ends of the single-rod body 1 of the utility model pass through the distance adjustment holes 22 on the corresponding arm body 21, and the rods 34 at both ends of the single-rod body 1 are adjusted and tightened (to prevent axial movement) with the corresponding outer sleeves 36 and sliding sleeves 35. At this time, the end face of the secondary support arm 5 is tightly pressed against the single-rod body 1 by the pressure adjusted by the inner nut 33 on the single-rod body 1, so that the main support arm 2 and the secondary support arm 5 are tightly pressed against the wall or door frame as a whole. When in use, the single-rod body 1 is adjusted to a suitable length, and then the main mounting seat 4 on the arm body 21 is tightly pressed against the wall or door frame. In actual use, as the single-rod body 1 moves downward by weight, the single-rod body 1 presses down the secondary support arm 5, and the lever principle force exerts downward pressure on the sliding sleeve 35 in the main support arm 2 to act on the secondary support arm 5, and then the secondary mounting seat 6 on the secondary support arm 5 is tightly pressed against the wall or door frame through the secondary support arm 5, so that the secondary pressing against the wall or door frame is achieved, which is more conducive to making the support more stable and safe.

[0045] Embodiment 5: It can be explained on the basis of embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4 that the main mounting seat 4 is provided with an anti-skid pad (not shown in the figure), and the anti-skid pad is formed with a plurality of horizontal stripes or honeycomb patterns to increase the friction force and make the installation more stable. And the auxiliary mounting seat 6 is provided with an anti-skid member (not shown in the figure), which plays a role in enhancing the friction force and also plays a role in buffering and protecting the anti-skid member, thereby improving the service life of the utility model.

[0046] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0047] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
