[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0017] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0018] See also Figure 1 The embodiment of the present invention provides a special equipment elevator car handrail fixing structure, and the special equipment elevator car handrail fixing structure includes:

[0019] A car 1, which is provided with an entrance and exit and a threaded hole. A car door 2 is installed at the entrance and exit of the car 1, and the car door 2 is used to control the opening and closing of the entrance and exit; a connecting mechanism 3, which is threadedly connected to the threaded hole opened in the car 1 and is detachable. There are two connecting mechanisms 3 and a linkage mechanism 4 is fixedly connected to the ends close to each other; a distance adjustment mechanism 5, which is fixedly connected to the two connecting mechanisms 3 and is used to adjust the distance between the two connecting mechanisms 3 to adapt to the threaded holes of different distances opened in the car 1; a handrail body 6, which is fixedly installed on the distance adjustment mechanism 5.

[0020] When using the special equipment elevator car handrail fixing structure, first rotate the control end of the distance adjustment mechanism 5 according to the distance of the threaded holes opened on the car 1, and the distance adjustment mechanism 5 can drive the two connecting mechanisms 3 to approach or move away from each other. After adjusting the distance between the two connecting mechanisms 3 to be consistent with the distance between the threaded holes, align the connecting mechanism 3 with the threaded holes, rotate the control end of the connecting mechanism 3, and the connecting mechanism 3 can be screwed into the threaded holes, thereby realizing the installation of the handrail body 6, and the linkage mechanism 4 can make the two connecting mechanisms 3 synchronously screwed into the threaded holes.

[0021] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the present utility model, the connecting mechanism 3 includes: a shell 31, which is fixedly connected to the power output end of the distance adjustment mechanism 5, a rotating column 32 is rotatably provided in the shell 31, the linkage mechanism 4 is fixedly connected to the two rotating columns 32, and a first bevel gear 33 is fixedly provided on the rotating column 32; a rotating rod 34, which is rotatably installed on the inner wall of the shell 31, and a second bevel gear 35 engaged with the first bevel gear 33 is fixed on the rotating rod 34; a bolt 36, which is fixedly connected to the rotating rod 34, and the bolt 36 can be screwed into the threaded hole to install the armrest body 6; a turning handle 37, which is fixedly connected to the rotating column 32 on one side.

[0022] like Figure 2As shown, as a preferred embodiment of the present utility model, the linkage mechanism 4 includes: a rotating sleeve 41, which is provided with two ends that are far away from each other and fixedly connected to the rotating columns 32 on both sides, and a linkage rod 42 is slidably provided on the rotating sleeves 41 on both sides, and the rotating sleeves 41 can slide along the linkage rod 42.

[0023] When installing the armrest body 6, align the two bolts 36 with the threaded holes and turn the handle 37. The handle 37 drives the lower rotating column 32 to rotate. The lower rotating column 32 drives the upper rotating column 32 to rotate through the rotating sleeve 41 and the linkage rod 42. The rotation of the rotating columns 32 on both sides drives the first bevel gear 33 thereon to rotate. The rotation of the first bevel gear 33 drives the second bevel gear 35 and the rotating rod 34 to rotate. The rotation of the rotating rod 34 drives the bolt 36 to rotate. The bolt 36 can enter the threaded hole by rotation, thereby completing the installation of the armrest body 6.

[0024] like Figure 2 As shown, as a preferred embodiment of the present utility model, the distance adjustment mechanism 5 includes: a support groove 51, which is fixedly connected to the armrest body 6, a screw rod 52 is rotatably provided on the inner wall of the support groove 51, a handle 53 is fixed on the screw rod 52, a partition 54 is fixedly provided in the middle of the screw rod 52, and the screw rod 52 on both sides of the partition 54 has opposite thread rotation directions; a guide rod 55, both ends of which are fixedly connected to the inner wall of the support groove 51, a threaded block 56 threadedly connected to the screw rod 52 is sleeved on the guide rod 55, and the threaded blocks 56 are distributed on both sides of the partition 54, and the shell 31 and the threaded block 56 are fixedly connected.

[0025] When adjusting the distance between the two connecting mechanisms 3, rotate the handle 53, and the handle 53 drives the screw rod 52 to rotate. The rotation of the screw rod 52 can make the threaded blocks 56 on both sides of the partition 54 approach or move away from each other along the guide rod 55, thereby driving the connecting mechanisms 3 on both sides to approach or move away from each other, and then the distance between the two connecting mechanisms 3 can be adjusted to the same distance as the threaded hole, which is convenient for installing the armrest body 6.

[0026] like Figure 4 As shown, as a preferred embodiment of the present invention, the armrest bodies 6 are provided in plurality and distributed from top to bottom on the support groove 51 , and the plurality of armrest bodies 6 are used to accommodate people of different heights.

[0027] By providing a plurality of armrest bodies 6, people of different heights can use the armrest more conveniently, thereby improving the riding experience of passengers.
