Description

Technical Field

[0001] This utility model relates to the field of elevator accessories technology, specifically to an elevator handrail that is easy to install and disassemble. Background Technology

[0002] Elevators are ubiquitous in our daily work and life. To further enhance the safety and comfort of elevator use, existing elevators are often equipped with handrails. With the elevator handrails, people can hold on while riding the elevator, which increases comfort and can also ensure the safety of users to a certain extent in emergency situations.

[0003] Many existing elevator handrails are retrofitted after the elevator is installed. During the retrofitting process, it is necessary to measure and position the handrail on the inner wall of the elevator car according to its size, and then use various connectors to stably fix the elevator handrail to the inner wall of the car, bringing convenience to people.

[0004] However, in actual engineering practice, certain errors are often unavoidable during the measurement and positioning process. When the error is small, it usually does not affect the installation. The metal connectors can be deformed to a certain extent by tapping, thus achieving the installation. However, when the error is large, it is necessary to remeasure and reposition. Repeated installation may affect the integrity of the inner wall of the elevator car and affect its appearance. In actual engineering practice, large errors are generally not encountered, but small errors cannot be avoided. This leads to inconvenience in installation on the one hand, and on the other hand, the deformation of metal parts caused by tapping will make disassembly difficult during later maintenance and replacement, causing inconvenience in use.

[0005] Therefore, a more convenient elevator handrail to install and disassemble is a technical problem that needs to be solved in existing engineering projects. Utility Model Content

The thickness of the circular end 61 is the same as the thickness of the circular groove 42. The circular end 61 is connected to the mating rod 62, and the mating rod 62 passes through the second circular through hole 43 so that the first base 4 is fitted onto the mating part 6. The second circular through hole 43... The diameter is consistent with that of the connecting rod 62; a first mounting hole 41 is provided around the first base 4, and the first base 4 is fixedly connected to the inner wall of the elevator car by installing self-drilling self-tapping screws 5 through the first mounting hole 41; the connecting rod 62 cooperates with the first connecting column 21, a first connecting hole 211 is provided on the first connecting column 21, and a threaded hole 63 is provided on the connecting rod 62. The first connecting column 21 is sleeved on the connecting rod 62, and the first connecting hole 211 and the threaded hole 63 cooperate and are connected with hex bolts 7.

[0031] A first pressure cap 3 is also provided between the first base 4 and the first connecting post 21. The diameter of the first pressure cap 3 is larger than the diameter of the first base 4. The first pressure cap 3 covers the first base 4. A first circular through hole 31 is provided on the first pressure cap 3. The first circular through hole 31 cooperates with the connecting rod 62. The connecting rod 62 passes through the first circular through hole 31. The outer diameter of the first connecting post 21 is larger than the diameter of the first circular through hole 31.

[0032] A groove 92 is provided at the bottom of the second base 9, and a second groove-shaped through hole 93 is provided above the groove 92. The connecting piece 6 is installed through the groove 92 and the second groove-shaped through hole 93. The round end of the connecting piece 6 matches the groove 92. The thickness of the round end 61 is the same as the thickness of the groove 92, and the diameter of the round end 61 is the same as the height of the groove 92. The width of the second groove-shaped through hole 93 is the same as the diameter of the connecting rod 62. The connecting rod 62 passes through the second groove-shaped through hole 93 so that the second base 9 is fitted onto the connecting piece 6. A second mounting hole 91 is provided around the second base 9. Self-drilling self-tapping screws 5 are installed through the second mounting hole 91 and fixedly connected to the inner wall of the elevator car.

[0033] The connecting rod 62 is engaged with the second connecting post 22. A second connecting hole 221 is provided on the second connecting post 22. The second connecting post 22 is sleeved on the connecting rod 62. The second connecting hole 221 is engaged with the threaded hole 63 and connected with an internal hex bolt 7.

The diameter of the second pressure cap 8 is larger than the diameter of the second base 9. The second pressure cap 8 covers the second base 9. A first groove-shaped through hole 81 is provided on the second pressure cap 8. The connecting rod 62 passes through the first groove-shaped through hole 81. The length of the first groove-shaped through hole 81 is smaller than the outer diameter of the second connecting post 22.

[0035] The principle of this utility model is as follows:

[0036] In use, the distance between the first connecting column 21 and the second connecting column 22 is used to measure and mark the installation position on the inner wall of the elevator car. Then, the connecting piece 2 is connected to the first base 4, and then pressed and fixed according to the marked position. The first base 4 is fixed to the inner wall of the car using self-drilling self-tapping screws 5 (dovetail screws).

[0037] After the first base 4 is fixed, the connector 2 is connected to the second base 9, and then fixed to the inner wall of the car with self-drilling and self-tapping screws 5 as marked.

[0038] After the above operations are completed, the handrail 1 can be installed. Align the first connecting post 21 and the second connecting post 22 with the two connecting rods 62 respectively, then press down on the handrail 1. After installation, tighten the hex bolts 7.

[0039] However, in actual operation, it is difficult to guarantee that the installation accuracy will not deviate. If there is a positional deviation during the measurement and installation of the first base 4 and the second base 9, it will be difficult to install accurately. In actual operation, the positional deviation is generally not very large. At this time, it can be installed by hammering, but the installation is relatively laborious. At the same time, if disassembly is required during subsequent maintenance or replacement, it will be difficult to disassemble due to the deformation of the metal parts caused by hammering. If the deviation is large, the hole can only be repositioned, which can easily damage the inner wall of the car and affect the aesthetics of use.

[0040] In actual installation, if there is a positional deviation, such as a small horizontal deviation, the position of the connector 2 in the second base 9 can be adjusted by sliding it left or right (keeping the second slotted through hole 93 horizontal during installation) to install the handrail 1. If there is a vertical deviation, the direction of the connector 2 in the first base 4 and the second base 9 can be rotated and the position of the connector 2 in the second base 9 can be adjusted. The same principle applies to deviations in both the horizontal and vertical directions, so it will not be elaborated further.

[0041] Through the above installation, the handrail 1 can be installed conveniently and stably. Even if there are some small measurement and installation errors, it will not affect the installation of the handrail 1 at all. After installation, it can be quickly disassembled and will not be affected by the deformation of metal parts, making it more convenient to use.
