Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, and particularly relates to a single bar for doors. Background Art

[0002] A single bar for doors is a fitness equipment for exercising the arms and the waist and abdomen. In the existing market, the single bar for doors includes a tube body and a pair of rod bodies that are telescopically arranged in the tube body. The rod bodies can be threadedly connected in the tube body. By rotating the rod bodies, the rod bodies can extend or contract in the tube body, so that the pair of rod bodies can respectively abut against the wall.

[0003] The single bar for doors in the prior art only uses friction to fix the single bar body. This fixing method is not applicable to a flat and smooth wall. That is to say, the fixing effect of the single bar for doors in the prior art on a smooth wall is poor, and it is easy to fall off, having potential safety hazards. Content of the Utility Model

[0004] The utility model provides a single bar for doors, aiming to solve the problem that the fixing effect of the single bar for doors in the prior art on a smooth wall is poor.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] A single bar for doors includes a fixing seat;

[0007] There are two fixing seats. A single bar body is arranged between the two fixing seats, and the two fixing seats are respectively arranged at both ends of the single bar body;

[0008] The fixing seat includes a housing, a suction cup is arranged on the housing, and a control component for controlling the suction cup to adsorb on the wall is arranged in the housing.

[0009] A further improved scheme: A sliding seat is further arranged in the housing, a driver for driving the sliding seat to move is further arranged in the housing, a supporting foot is arranged on the sliding seat, and one end of the supporting foot far away from the sliding seat extends out of the housing;

[0010] Wherein, when the suction cup is not adsorbed on the wall, the sliding seat drives the supporting foot to contract towards the housing, and when the suction cup is adsorbed on the wall, the sliding seat drives the supporting foot to extend out of the housing.

[0011] Based on the above technical solution: When the suction cup successfully adsorbs to the wall, the driver drives the slide to drive the support feet to automatically extend out of the housing, providing an additional support point for the fixed seat. This automatic support mechanism ensures the stability of the fixed seat during operation, reducing the risk of shaking or falling caused by improper operation or external interference. The extension of the support feet increases the contact area between the fixed seat and the wall, and the support feet can effectively prevent the fixed seat from accidentally falling.

[0012] Further improved solution: There are four support feet, and the four support feet are evenly distributed around the housing.

[0013] Based on the above technical solution: The four support feet provide more support points compared to a single or a small number of support feet, making the fixed seat more stable when adsorbed to the wall surface. The multi-point support effectively disperses the torque, reducing the risk of shaking and tilting.

[0014] Further improved solution: The support feet are rotatably connected to the slide, and through holes for the support feet to pass through are provided on the housing.

[0015] Based on the above technical solution: When the suction cup is not adsorbed to the wall surface, the support feet can rotate smoothly and retract into the housing, thus avoiding friction with the wall or other obstacles, and reducing the space occupied by the fixed seat during storage.

[0016] Further improved solution: A foot pad for increasing the contact area between the support foot and the wall is provided at the end of the support foot away from the slide.

[0017] Based on the above technical solution: The design of the foot pad significantly increases the contact area between the support foot and the wall. This helps to disperse the pressure exerted by the horizontal bar on the wall, reducing the unstable factors caused by excessive single-point force, thereby enhancing the stability of the horizontal bar on the door during use. The increased contact area and the friction of the foot pad help to prevent the horizontal bar on the door from sliding or shifting during use, ensuring the safety of users.

[0018] Further improved solution: The driver is a guide cylinder rotatably arranged in the housing, an external thread is provided on the guide cylinder, and an internal thread is provided on the slide.

[0019] Based on the above technical solution: The guide cylinder restricts the movement of the slide in other degrees of freedom except the sliding direction, making the slide can only slide along the axis direction of the guide cylinder. This restriction enhances the overall stability of the device, reducing the risk of the suction cup shaking or falling caused by the instability of the slide. Moreover, the guide cylinder can also drive the slide, simplifying the structure of the housing.

[0020] Further improved solution: The support feet are rotatably connected to the slide through a rotating shaft.

[0021] Based on the above technical solution: Since the supporting feet are rotatably connected to the sliding seat through a rotating shaft, they can be flexibly adjusted according to the angle and shape of the wall surface. This design enables the fixing seat to adapt to walls with different inclinations or irregular shapes, ensuring stable support. Moreover, the supporting feet can be easily retracted into the housing or extended from the housing.

[0022] Further improved solution: A sealed cavity is formed between the housing and the suction cup, and the control assembly includes a negative pressure pump disposed in the housing, and the negative pressure pump communicates with the sealed cavity.

[0023] Based on the above technical solution: The negative pressure pump generates negative pressure through operation, extracting the air in the sealed cavity, thereby creating a vacuum state between the suction cup and the wall surface. This negative pressure effect enables the suction cup to firmly adsorb on the wall surface, providing strong adsorption ability, and the fixing seat remains stable in various working states, not easily falling off or shaking.

[0024] Further improved solution: A cavity is provided between the housing and the suction cup, and a pull rod for controlling the suction cup to enter or leave the cavity is disposed in the housing, and the control assembly includes a driving mechanism for driving the pull rod.

[0025] Based on the above technical solution: By driving the pull rod through the driving mechanism, the suction cup can be quickly pulled into or out of the cavity, thereby achieving rapid adsorption or release from the wall surface. The user can achieve the adsorption and release of the suction cup through simple control, without complex operation steps, improving the convenience of use.

[0026] Further improved solution: The driving mechanism includes a motor, a cam is disposed on the output shaft of the motor, one end of the cam away from the output shaft is rotatably connected to the upper end of the pull rod, and the lower end of the pull rod is connected to the suction cup.

[0027] Based on the above technical solution: The motor drives the cam to rotate, and the cam drives the pull rod to move up and down during rotation, thereby enabling the suction cup to accurately enter or leave the cavity, avoiding problems such as unstable adsorption or incomplete release caused by position deviation. Through the mechanical transmission method of the cam and the pull rod, the power of the motor can be stably transmitted to the pull rod, and then drive the movement of the suction cup. This transmission method is simple and reliable, reducing energy loss and improving transmission efficiency.

[0028] The beneficial effects of the present utility model are:

[0029] The utility model is provided with a suction cup on the housing, and a control component for controlling the suction cup to adsorb on the wall is arranged inside the housing. Due to the suction cup design, the single-bar on the door can be firmly adsorbed on a smooth and flat wall surface, and is no longer limited by the material or structure of the wall surface. This enables it to be used in more types of home or gym environments.

[0030] Users do not need to use complex tools or perform cumbersome installation steps. They only need to align the suction cup on the fixing base with the wall surface and operate the control component to achieve quick installation. This greatly reduces the installation difficulty and time cost.

[0031] The adsorption force of the suction cup can ensure that the single-bar remains stable and does not shake during use, thereby improving the safety and user experience of users. Brief Description of the Drawings
