Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and particularly relates to a protection structure for the side wall of a car. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin for carrying passengers or goods in multi-story buildings. There are also step-type ones, with tread plates running continuously on a track, commonly known as escalators or moving sidewalks, which are fixed lifting devices serving specified floors. The vertical lift elevator has a car that runs between at least two columns of vertical or inclined rigid guide rails with an inclination angle less than 15°. The car size and structural form facilitate the entry and exit of passengers or the loading and unloading of goods.

[0003] Chinese patent document CN221607533U discloses an internal protection structure for an elevator car, including a bottom plate, and three side plates are fixedly connected to the top of the bottom plate. When a material impacts the outside of the rectangular plate in the utility model, the rectangular plate drives the round rod to move through the vertical rod, the round rod drives the sealing ring to slide inside the circular tube, the cross block drives the corresponding vertical block to move to compress the elastic airbag, the vertical block drives the rectangular block to move through the flexible steel wire, and the rectangular block drives the cylinder to move and slide outside the square rod to stretch the spring. At this time, under the action of the elastic force of the elastic airbag, the elastic force of the spring and the negative pressure in the circular tube, the impact of the material is effectively buffered. At the same time, the setting of the damper makes the buffering performance concentrated, and can effectively buffer and protect the elevator car, avoiding damage to the elevator caused by the impact of the material, not requiring frequent maintenance, and greatly improving the service life of the elevator at the same time.

[0004] The following problems exist in the prior art:

[0005] This protection structure is fixedly connected to the inner side wall of the elevator car. However, in reality, these protection structures may be progressively affected by external factors, such as deliberate damage by children, etc. This makes it necessary to perform maintenance and replacement operations, but there are no components for quick disassembly on it, resulting in difficulty in removing and replacing the rectangular plate and increasing the maintenance difficulty.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2As shown in the figure, a protection structure for the side wall of a car body includes a car body 1. At the positions near the four corners on the upper and lower sides of the inner side of the car body 1, four columns 2 are fixedly connected. A fixing mechanism 3 is movably sleeved inside each of the four columns 2. A mounting plate 4 is movably sleeved between two adjacent columns 2, and one mounting plate 4 is distributed on each of the left, right, and rear sides. Buffer pads 5 are fixedly connected to the sides of the three fixing mechanisms 3 close to each other. At the positions slightly above the middle of the sides close to each other of the two mounting plates 4 on the left and right sides, suspension mechanisms 6 are rotatably connected.

[0025] It should be noted that the buffer pads 5 are used to reduce the impact damage of the passengers in the elevator on the inner side wall of the car body 1. Cross bars are used to connect the four columns 2 to improve the overall structural strength.

[0026] As Figure 3 、 Figure 4 As shown in the figure, the fixing mechanism 3 includes a limiting column 31. The outer side of the limiting column 31 is movably sleeved inside the column 2. A number of fixing components 32 evenly distributed up and down are movably sleeved on the inner side wall of the limiting column 31. The fixing component 32 includes a clamping plate 321. The outer side of the clamping plate 321 is movably sleeved inside the inner side wall of the column 2. The side of the outer side of the clamping plate 321 away from the mounting plate 4 is attached to the side wall of the limiting column 31. The side of the outer side of the clamping plate 321 away from the limiting column 31 is movably sleeved in the clamping holes on the left and right sides of the mounting plate 4.

[0027] It should be noted that the limiting column 31 is used to block the clamping plate 321, so that the clamping plate 321 cannot move. When the clamping plate 321 is clamped into the clamping holes on the left and right sides of the mounting plate 4, the clamping plate 321 fixes the mounting plate 4.

[0028] As Figure 3 、 Figure 4 As shown in the figure, two limiting rods 322 distributed up and down are fixedly connected to the side of the clamping plate 321 away from the mounting plate 4. The outer sides of the limiting rods 322 are movably sleeved inside the vertical plates on the upper and lower sides of the inner side wall of the column 2. The outer sides of the two limiting rods 322 are both movably sleeved with first springs 323. A number of annular grooves 33 linearly distributed are opened on the outer side of the limiting column 31.

[0029] It should be noted that when the limiting column 31 is lifted upward so that the annular groove 33 is aligned with the clamping plate 321, the limiting column 31 cannot block the clamping plate 321. The shape of the side of the clamping plate 321 away from the limiting column 31 is an isosceles trapezoid, so that the mounting plate 4 can be removed from the clamping plate 321. The first spring 323 is used to limit the position of the clamping plate 321.

[0030] As Figure 4As shown, a bottom plate 34 is fixedly connected to the lower end of the column 2. A lock core 35 is movably installed on the upper side of the bottom plate 34. A connecting plate 36 is fixedly connected to the lower end of the limit post 31. A fixed cylinder 37 is fixedly connected to the upper side of the connecting plate 36. The inner side of the fixed cylinder 37 is movably sleeved on the outer side of the lock core 35.

[0031] It should be noted that there are engaging teeth on the lock core 35, and corresponding vertical grooves are provided on the inner side of the fixed cylinder 37. In the initial state, the engaging teeth are not opposite to the vertical grooves, so that the limit post 31 cannot move upward. By using a special key to rotate the lock core 35, the engaging teeth are aligned with the vertical grooves, enabling the limit post 31 to move upward.

[0032] As Figure 5 shown, the suspension mechanism 6 includes a round rod 61. The front and rear ends of the round rod 61 are rotatably connected to two symmetrically distributed rotating rods 62. The upper ends of the rotating rods 62 are rotatably connected to the middle upper positions on the closer sides of the left and right mounting plates 4. The inner sides of the two rotating rods 62 are both rotatably connected to a rotating shaft 63. Limit rods 64 are fixedly connected to the left and right ends of the two rotating shafts 63. The outer sides of the limit rods 64 are movably sleeved in fixed grooves opened on the closer sides of the left and right mounting plates 4.

[0033] It should be noted that the shape of the notch of the fixed groove is the same as the shape of the limit rod 64 after rotating 90 degrees. By rotating the limit rod 64 to align it with the notch of the fixed groove, the limit rod 64 can be movably sleeved into the fixed groove. Then, by rotating the limit rod 64, the limit rod 64 cannot be pulled out of the fixed groove, fixing the round rod 61.

[0034] As Figure 5 shown, torsion springs 65 are movably sleeved on the outer sides of the two rotating shafts 63.

[0035] It should be noted that the second spring 65 is a torsion spring, which limits the limit rod 64 in the initial state to prevent it from rotating freely.

[0036] Working principle of the utility model: First, the limit post 31 is used to block the clamping plate 321, so that the clamping plate 321 cannot move. When the clamping plate 321 is inserted into the clamping holes on the left and right sides of the mounting plate 4, the clamping plate 321 fixes the mounting plate 4. Lift the limit post 31 to align the annular groove 33 with the clamping plate 321, so that the limit post 31 cannot block the clamping plate 321. The shape of the side of the clamping plate 321 away from the limit post 31 is an isosceles trapezoid, so that the mounting plate 4 can be removed from the clamping plate 321. The first spring 323 is used to limit the position of the clamping plate 321. There are teeth on the lock core 35, and corresponding vertical grooves are provided inside the fixed cylinder 37. In the initial state, the teeth do not face the vertical grooves, so that the limit post 31 cannot move upward. Use a special key to rotate the lock core 35 so that the teeth are aligned with the vertical grooves, so that the limit post 31 can move upward. Rotate the lock core 35 with a special key, so that the limit post 31 can move upward, so that the mounting plate 4 can be quickly removed from the inner wall of the car body 1. It is convenient to install, simple to disassemble, and easy to maintain. Try to shorten the time for removing the mounting plate 4 during maintenance work. Finally, the shape of the notch of the fixed groove is the same as the shape of the limiting rod 64 after rotating 90 degrees. Rotate the limiting rod 64 so that the limiting rod 64 is aligned with the notch of the fixed groove, so that the limiting rod 64 can be movably sleeved into the fixed groove. Then rotate the limiting rod 64 so that the limiting rod 64 cannot be pulled out of the fixed groove, so that the round rod 61 is fixed. The second spring 65 is a torsion spring, so that the limiting rod 64 in the initial state is limited to prevent it from rotating freely. Fix the round rod 61 through the limiting rod 64, so that the round rod 61 can be in the lower side and the upper side, so that the device can place items for the people taking the elevator, or can be turned upward when there are many people to reduce the occupation of the space in the elevator. The adjustment is convenient and fast.
