Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a door-mounted horizontal bar with a higher safety factor. Background Art

[0002] With the improvement of people's living standards, people pay more and more attention to physical exercise and body shaping. In order to facilitate exercise, door horizontal bars have appeared on the market. The existing door horizontal bars on the market include telescopic rods and support seats arranged at both ends of the telescopic rods. When in use, the telescopic rods are extended to make the support seats squeeze the wall to generate friction for fixing. Although it can play a fixing role to a certain extent, when the load becomes heavier or when the user is exercising, the force borne by the door horizontal bar may be greater than the friction between the support seat and the wall, causing the door horizontal bar to fall off, causing a safety hazard.

[0003] Therefore, there appeared a Chinese invention patent application with application publication number CN114652997A, which is a horizontal bar on a door, including a horizontal bar body, both ends of the horizontal bar body are provided with main support seats for leaning against the door frame, and both ends of the horizontal bar body are provided with secondary support seats for leaning against the door frame. However, this secondary support seat is separated from the main support seat, and the secondary support seat supports the horizontal bar body through a support rod. This structure requires one end of the support rod to be connected to the secondary support seat, and the other end of the support rod to be fixedly connected to the horizontal bar body. The support rod is inevitably connected to the secondary support seat and the horizontal bar body respectively. If the connection is not firm enough, it is easy to have a problem of structural instability. In serious cases, the installation is not firm enough during use, which may cause the user to fall and cause damage. In view of this situation, it is necessary to improve the existing technology.

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. 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 , Figure 2 and Figure 3A horizontal bar on a door with a higher safety factor includes a horizontal bar body 1 and main support seats 2 for leaning against a door frame (or wall) at both ends of the horizontal bar body 1, and a secondary support seat 3 is arranged on each main support seat 2. The main support seat 2 and the secondary support seat 3 are connected by a movable structure 4. After the secondary support seat 3 rotates with the movable structure 4 as a fulcrum, the secondary support seat 3 is in conflict with the back of the main support seat 2. This is conducive to realizing the effect on the door frame (or wall) through the secondary support seat 3, and is more conducive to improving the stability of the utility model installed on the door frame (or wall). Since the main support seat 2 and the secondary support seat 3 are connected by the movable structure 4, the connection between the components is directly reduced, which is also conducive to improving the stability of the utility model installed on the door frame (or wall), and ultimately improving the safety of use.

[0034] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the movable structure 4 includes a fixed seat 41 arranged on the main support seat 2 and a mounting seat 42 arranged on the auxiliary support seat 3, a torsion spring 43 is arranged between the fixed seat 41 and the mounting seat 42, and an axis core 44 is arranged in the middle of the torsion spring 43, which is conducive to movably connecting the fixed seat 41 and the mounting seat 42 together, and a sliding block 45 is arranged on the back of each main support seat 2, and a matching groove 46 for matching with the sliding block 45 is arranged on the mounting seat 42, and an inclined surface 47 is arranged on the sliding block 45. After the support seat 3 rotates with the torsion spring 43 as the fulcrum, the matching groove 46 on the mounting seat 42 is caused to abut against the inclined surface 47 of the sliding block 45. In this way, when the utility model is installed on the door frame (or wall), the auxiliary support seat 3 will also act on the door frame (or wall). This not only has a simple structure and reduces the connecting parts between the auxiliary support seat 3 and other components, but also helps to improve the stability of the utility model installed on the door frame (or wall), ultimately improving the safety of use. Moreover, the operation is also simple and convenient, which is convenient for improving the safety of use.

[0035] I want to explain that if Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the fixing seat 41 and the main supporting seat 2 are integrally formed, and the mounting seat 42 and the auxiliary supporting seat 3 are integrally formed, which is beneficial to greatly improve the firmness and stability of the structure.

[0036] Among them Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7and Figure 8 As shown, a mounting groove 411 is provided on the fixing seat 41, a partition plate 412 is provided between the mounting grooves 411, a torsion spring 43 is placed in the mounting groove 411, and an assembly groove 421 for placing the fixing seat 41 is provided on the mounting seat 42, a device groove 422 matching the mounting groove 411 is provided in the assembly groove 421, and one end of the torsion spring 43 is located on the fixing seat 41, and the other end of the torsion spring 43 is located on the mounting seat 42. This arrangement is conducive to the installation of the torsion spring 43, and is conducive to realizing the rotation of the auxiliary support seat 3 through the torsion spring 43 to contact the inclined surface 47 of the sliding block 45 on the back of the main support seat 2, which greatly improves the fastening and stability with the door frame (or wall) during use, improves the safety of use, and also enables the utility model to clamp the auxiliary support seat 3 by utilizing the action of the torsion spring 43.

[0037] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Fig. 9 As shown, a first level 11 is provided on the horizontal bar body 1, and in this embodiment, the first level 11 is provided in the middle position of the horizontal bar body 1, and this arrangement is conducive to better grasping whether the horizontal bar body 1 is level after installation, which is more convenient for users to use. It is to be noted that a second level 21 is provided on the main support seat 2, and in this embodiment, each main support seat 2 is provided with a second level 21, and this arrangement is conducive to ensuring that the main support seat 2 is placed horizontally.

[0038] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Fig. 9 As shown, the front of the main support seat 2 and the auxiliary support seat 3 are both provided with wear-resistant pads 5, which are helpful to increase the friction with the contacting door frame (or wall) and improve the stability of the installation. It should be noted that the wear-resistant pads 5 are made of rubber material, which reduces the difficulty of production and is easy to produce.

[0039] The utility model first adjusts the horizontal bar body 1 so that the main support seats 2 at both ends of the horizontal bar body 1 abut against the door frame (or wall), and then adjusts the auxiliary support seat 3 to abut against the inclined surface 47 on the back of the auxiliary support seat 3 at one end of the mounting seat 42. In this way, not only the main support seat 2 abuts against the door frame (or wall), but also the auxiliary support seat 3 abuts against the door frame (or wall), so that the horizontal bar body 1 is tightly installed between the two door frames (or wall), increasing the force that the horizontal bar on the door can withstand; and when it needs to be disassembled, it is only necessary to shorten the length of the horizontal bar body 1, so that the horizontal bar body 1 can be disassembled from the middle of the two door frames (or wall), which is convenient for people to operate.

[0040] 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 existing technology. The horizontal bar body, main support seat and auxiliary support seat are commonly used structures in the existing technology and will not be described in detail here.

[0041] 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.
