[0018] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.
[0019] Example 1
[0020] An elevator car handrail structure, installed inside the car body 5, includes: a handrail body 1, two sets of fixing rods 2, an inner heating component 3, and an outer sheath 4. One side of the fixing rod 2 is threaded to the handrail body 1, and the other side of the fixing rod 2 is fixedly connected to the car body 5. The inner heating component 3 includes an annular core 31, a cage-like heating wire 32, a connecting socket 33, a wire 34, and a power plug 35. The handrail body 1 has a cavity 11 inside. The annular core 31 is disposed inside the cavity 11 and fits against the inner wall of the cavity 11. The cage-like heating wire 32 is disposed inside the annular core 31. The connecting socket 33 is electrically connected to the head end of the cage-like heating wire 32. The plug 341 at the front end of the wire 34 is electrically plugged into the connecting socket 33. The wire 34 passes through the inside of one set of fixing rods 2 to the outside of the car body 5 and is connected to the power plug 35. The outer sheath 4 is detachably sleeved on the outside of the handrail body 1.
[0021] As a further preferred embodiment, the outer sheath 4 includes a first sheath 41 and a second sheath 42. The first sheath 41 and the second sheath 42 are respectively fitted onto both sides of the handrail body 1, closing both ends of the handrail body 1. Both the first sheath 41 and the second sheath 42 are provided with through grooves 44 to avoid the fixing rod 2. The first sheath 41 and the second sheath 42 are fitted onto both sides of the handrail body 1, closing both ends of the handrail body 1, thus providing protection and insulation for both ends of the handrail body 1. The through grooves 44 are provided to avoid the fixing rod 2 during the installation of the first sheath 41 and the second sheath 42, allowing the sheaths to fit tightly against the handrail body 1, ensuring the accuracy and stability of the installation. This split design facilitates operation during installation and disassembly, and also better adapts to the connection structure between the handrail body 1 and the fixing rod 2.
[0022] As a further preferred embodiment, the outer sheath 4 also includes a third sheath 43. The third sheath 43 is fitted onto the middle of the handrail body 1, with its front and rear ends contacting the first sheath 41 and the second sheath 42. The bottom ends of the third sheath 43 are connected and fixedly fitted onto the handrail body 1 via Velcro fasteners. The third sheath 43 covers the middle of the handrail body 1 and cooperates with the first sheath 41 and the second sheath 42 to achieve complete coverage of the handrail body 1. The Velcro fastener connection method allows the third sheath 43 to be easily installed and removed. During installation, simply align and stick the first and last ends of the Velcro fasteners to fix it onto the handrail body 1; during removal, gently peel off the Velcro fasteners to remove it.
[0023] As a further preferred embodiment, the cavity 11 of the handrail body 1 extends to the outside on both sides, and end caps 12 are inserted into both ends of the cavity 11. When installing the internal heating assembly 3, components such as the annular base core 31 and the cage-shaped heating wire 32 can be sequentially placed into the cavity from one side of the cavity 11; during disassembly, each component can also be easily removed. The end caps 12 at both ends of the cavity 11 can seal both ends of the cavity 11, preventing dust, debris, etc. from entering the cavity 11 and affecting the normal operation of the internal heating assembly 3; on the other hand, it can also play a certain role in heat preservation.
[0024] As a further preferred embodiment, the end of the fixing rod 2 is connected to a flange seat 21, and the flange seat 21 is fixedly connected to the car body 5 by bolts.
[0025] As a further preferred embodiment, one set of the fixing rods 2 has a guide channel 22 inside, and the wire 34 passes through the guide channel 22 to the outside of the car body 5 and connects to the power plug 35. The wire 34 can pass through the guide channel 22 from the inside of the handrail body 1 to the outside of the car body 5.
[0026] like Figures 1-4 As shown, the working principle of this utility model is as follows: The handrail structure is connected to an external power source via the power plug 35. Current is transmitted through the wire 34 and the connecting socket 33 to the cage-shaped heating wire 32, which generates heat under the action of the current. Since the cage-shaped heating wire 32 is located inside the annular base core 31, on the one hand, the heat it generates can be evenly transferred to the handrail body 1 through the annular base core 31, thereby heating the handrail body 1; on the other hand, the structure of the cage-shaped heating wire 32 can support the annular base core 31, making it firmly attached to the inner wall of the cavity of the handrail body 1, ensuring the stability and uniformity of heat transfer. The outer sheath 4 is fitted on the outside of the handrail body 1, which can reduce the loss of heat to the external environment and play a role in heat preservation.
[0027] In winter, the handrail structure can heat the handrail body 1 through the internal heating component 3, keeping the handrail surface warm and preventing passengers from touching the cold handrail, greatly improving passenger comfort when riding the elevator. At the same time, the heat insulation effect of the outer sheath 4 further enhances the heating effect, reduces heat loss, and lowers energy consumption.
[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
