In this utility model, through the cooperation of a motor, lead screw, slider, crossbar, extension rod, and electric telescopic rod, the output end of the motor drives the lead screw to rotate when it is working. Since the lead screw and slider are connected by a thread, and the lead screw is longitudinally set in the groove inside the mounting base, the rotation of the lead screw can cause the slider to move up and down in the groove, thereby driving the crossbar fixedly connected to it to move up and down. The extension rod inserted inside one end of the crossbar will move synchronously with the crossbar, thereby realizing the adjustment of the handrail height. The output end of the electric telescopic rod is fixedly connected to the handrail, and its telescopic action can change the distance between the handrail and the human body. This structure can flexibly adjust the height of the handrail and the distance from the human body according to the user's height and weight, which can better meet the usage needs of people of different heights and weights, greatly improve the convenience and comfort of use, and avoid the problem of inconvenience caused to some users due to the fixed position of the handrail. It allows the elderly to more easily use the handrail to support their body and ensure their safety during use.

[0013] 2. In this utility model, through the T-shaped groove and limiting groove opened on the handrail pressing surface, and the cooperation of the T-shaped rod and limiting rod fixedly connected on the anti-slip mat, when installing the anti-slip mat, simply align the T-shaped rod on the anti-slip mat with the T-shaped groove on the handrail pressing surface and insert it, so that the limiting rod is simultaneously inserted into the limiting groove, thus realizing the installation of the anti-slip mat. When the anti-slip mat needs to be replaced after prolonged use, it can be easily removed by reversing the operation. This structure facilitates the disassembly and replacement of the anti-slip mat, ensuring that the anti-slip mat always maintains good anti-slip performance, providing reliable anti-slip protection for the elderly when using handrails, reducing the risk of the elderly slipping due to wet handrail surfaces, and further improving the safety and practicality of the device.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a barrier-free device for elderly care buildings, including a mounting base 1, a groove 2 on the inner side of the mounting base 1, a rotatable lead screw 8 longitudinally arranged inside the groove 2, a slider 3 threadedly connected to the surface of the lead screw 8, a motor 9 fixedly connected to the bottom of the mounting base 1, the output end of the motor 9 fixedly connected to the bottom end of the lead screw 8, a crossbar 4 fixedly connected to the surface of the slider 3, an extension rod 5 inserted into the inner side of one end of the crossbar 4, and a handrail 6 fixedly connected to the end of the extension rod 5 away from the crossbar 4. An electric telescopic rod 10 is fixedly connected to the surface of the handrail 6. The output end of the electric telescopic rod 10 is fixedly connected to the handrail 6. An inclined brace 11 is provided between the slider 3 and the crossbar 4. The two ends of the inclined brace 11 are fixedly connected to the crossbar 4 and the slider 3, respectively. The mounting base 1 is provided with mounting holes 12. There are two sets of mounting holes 12, and each set has three mounting holes 12. A height adjustment button 13 and a distance adjustment button 14 are provided on the side of the handrail 6 away from the extension rod 5. An anti-slip pad 7 is provided on the pressing surface of the handrail 6. The anti-slip pad 7 is made of elastic rubber.

[0019] The beneficial effects achieved in this embodiment 1 are as follows: the handrail 6 can be flexibly adjusted in position through the coordinated action of the motor 9, lead screw 8, slider 3, crossbar 4, extension rod 5, and electric telescopic rod 10. After the motor 9 is started, its output end drives the lead screw 8 to rotate. The rotation of the lead screw 8 causes the slider 3 to move up and down along the slide groove 2, thereby driving the crossbar 4, which is fixedly connected to it, to move up and down accordingly. The extension rod 5, which is inserted into the inner side of one end of the crossbar 4, moves along with the crossbar 4, thereby achieving the adjustment of the height of the handrail 6. At the same time, the output end of the electric telescopic rod 10 is fixed to the handrail 6, and its telescopic action can change the distance between the handrail 6 and the human body. This structural design fully considers the differences in height and weight of different users, and can flexibly and precisely adjust the height of the handrail 6 and its distance from the human body according to the actual situation, which well meets the needs of users. The diverse usage needs greatly enhance the convenience and comfort of the entire device. The diagonal brace 11 between the slider 3 and the crossbar 4 is fixedly connected to the crossbar 4 and the slider 3 at both ends. The presence of the diagonal brace 11 enhances the stability of the connection structure between the crossbar 4 and the slider 3, making the crossbar 4 more stable during the up-and-down movement of the slider 3 and during daily use, and less prone to shaking or deformation. The mounting base 1 is provided with two sets of mounting holes 12, with three holes in each set. This design makes the mounting base 1 more secure in the elderly care building. The handrail 6 is provided with a height adjustment button 13 and a distance adjustment button 14 on the side away from the extension rod 5. The setting of these two buttons allows users or caregivers to easily and intuitively adjust the height and distance of the handrail 6.

[0020] Example 2: As Figure 4As shown, the pressing surface of the handrail 6 is provided with a T-shaped groove 15 and a limiting groove 16. The anti-slip pad 7 is fixedly connected to a T-shaped rod 17 and a limiting rod 18 on the side facing the pressing surface of the handrail 6. The T-shaped rod 17 is slidably connected inside the T-shaped groove 15, and the limiting rod 18 is inserted inside the limiting groove 16.

[0021] The beneficial effects achieved in this embodiment 2 are as follows: Through the T-shaped groove 15 and the limiting groove 16 opened on the pressing surface of the handrail 6, and the cooperation of the T-shaped rod 17 and the limiting rod 18 fixedly connected on the anti-slip pad 7, when installing the anti-slip pad 7, simply align the T-shaped rod 17 on the anti-slip pad 7 with the T-shaped groove 15 on the pressing surface of the handrail 6 and insert it, so that the limiting rod 18 is simultaneously inserted into the limiting groove 16, thus realizing the installation of the anti-slip pad 7. When the anti-slip pad 7 needs to be replaced after a long period of use, it can be easily removed by reversing the operation. This structure facilitates the disassembly and replacement of the anti-slip pad 7, enabling the anti-slip pad 7 to always maintain good anti-slip performance, providing reliable anti-slip protection for the elderly when using the handrail 6, reducing the risk of the elderly slipping due to the wet surface of the handrail 6, and further improving the safety and practicality of the device.

[0022] The working principle of this embodiment is as follows: In use, firstly, based on the actual installation location and needs in the elderly care building, the mounting base 1 is securely installed on the wall or corresponding support structure using the mounting holes 12 on the mounting base 1 and appropriate fasteners (such as screws), ensuring the entire device is stably installed. When the height of the handrail 6 needs to be adjusted to accommodate different user heights, the user or caregiver can press the height adjustment button 13 on one side of the handrail 6. This button will trigger the corresponding circuit control signal, causing the motor 9 at the bottom of the mounting base 1 to start working. The output of the motor 9 drives the lead screw 8 to rotate. The lead screw 8 and the slider 3 are connected by a thread, and the lead screw 8 is longitudinally confined within the groove 2 inside the mounting base 1. Therefore, the rotation of the lead screw 8 is converted into the vertical linear movement of the slider 3 within the groove 2. The movement of the slider 3 drives the crossbar 4, which is fixedly connected to it, to move up and down synchronously. The extension rod 5 inserted at one end of the crossbar 4 also moves accordingly, ultimately raising or lowering the height of the armrest 6 until it is adjusted to a suitable height position to meet the user's needs for comfortable grip and support. To adjust the distance between the armrest 6 and the human body to accommodate different body types, the far-hand side of the armrest 6 can be pressed. When the adjustment button 14 is pressed, the electric telescopic rod 10 receives a corresponding control signal. The electric telescopic rod 10 then extends or retracts according to the signal. Since the output end of the electric telescopic rod 10 is fixedly connected to the handrail 6, its extension and retraction process changes the distance between the handrail 6 and the user, adjusting the handrail 6 to a position that is easy for the user to grip and provides the most comfortable and safest use. During daily use, the anti-slip pad 7 on the pressing surface of the handrail 6 plays an important anti-slip role. This is achieved through the sliding engagement of the T-shaped rod 17 with the T-shaped groove 15 on the pressing surface of the handrail 6, and the interaction between the limiting rod 18 and the limiting groove 16. The anti-slip pad 7 is stably installed on the handrail 6. When the elderly person grasps the handrail 6, the anti-slip pad 7 uses its own elastic rubber material to make close contact with the elderly person's hand, increasing friction and preventing the elderly person from losing balance and falling due to hand slippage. If the anti-slip pad 7 becomes worn or its anti-slip effect deteriorates after long-term use, the old anti-slip pad 7 can be removed and replaced with a new one according to the above-mentioned anti-slip pad 7 disassembly and assembly method. This will continue to ensure the good anti-slip performance of the handrail 6 and ensure that the barrier-free device of the entire elderly care building continuously, stably, safely and reliably assists the elderly person in their daily life activities.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
