Description
Technical Field
[0001] The utility model relates to the technical field of elevator doors, and in particular to an elevator door with an anti-pinch function. Background Art
[0002] An elevator is a fixed lifting device serving specified floors. A vertical elevator has a car that runs between at least two columns of vertical rigid guide rails. The car size and structural form facilitate the entry and exit of passengers or the loading and unloading of goods. Conventionally, regardless of its driving method, an elevator is generally referred to as a vertical transportation tool within a building.
[0003] During the use of existing elevators, maintenance and inspection are often required. During the maintenance process, when the elevator does not sense the situation inside the elevator door, it is very easy to have a clamping and closing situation, resulting in poor lighting. At this time, the maintenance personnel may need to come down to open the elevator door again to make the lighting better. To ensure good lighting during maintenance, maintenance personnel usually place an object in the middle of the elevator door, so that when the elevator door closes, the elevator door touches the object and cannot close, and thus returns. Repeated closing operations of the elevator door easily cause the elevator door to push the object to move until the distance between the two sides of the elevator door is the maximum length of the object, resulting in a constant distance and gradually poor lighting during the maintenance process. At this time, the staff needs to come down to continue adjusting the elevator door, which greatly affects the maintenance process and increases the danger of maintenance operations.
[0004] Therefore, there is an urgent need to develop an elevator door structure that can prevent the elevator door from closing during elevator maintenance, so as to obtain good lighting during maintenance and promote the progress of elevator maintenance. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an elevator door with an anti-pinch function, so as to prevent the elevator door from closing during elevator maintenance and promote the progress of elevator maintenance.
[0006] The purpose of the utility model can be realized by the following technical solutions:
[0007] An elevator door with an anti-pinch function includes a first elevator door and a second elevator door. A moving cavity is arranged inside the first elevator door, and a horizontal circular groove is opened inside the second elevator door;
[0008] A moving rod that can extend out of the first elevator door is slidably arranged inside the moving cavity. The moving rod is connected with a pushing component for driving the horizontal movement of the moving rod; the moving rod can extend into the circular groove of the second elevator door when the first elevator door and the second elevator door are normally closed;
[0009] An opening groove is formed on the outer wall of the moving rod close to the second elevator door. The opening groove communicates with the sliding cavity inside the moving rod. A clamping prevention block and a moving component capable of driving the clamping prevention block to extend out of the opening groove and block the entrance of the circular groove are arranged in the sliding cavity.
[0010] Further, first sliding grooves are formed on both inner walls of the moving cavity. A moving rod slider capable of horizontally sliding in the first sliding grooves is connected to the end of the moving rod away from the second elevator door.
[0011] Further, the pushing component includes a movable rod movably connected to the moving rod and a telescopic rod movably connected to the movable rod. The telescopic rod is connected with a driving member for driving the telescopic rod to expand and contract.
[0012] Furthermore, the driving member is connected to the elevator control system, and the opening and closing of the driving member can be remotely controlled.
[0013] Further, a first movable shaft is installed on the moving rod, and one end of the movable rod is hinged to the first movable shaft.
[0014] Further, a second movable shaft is installed at the top end of the telescopic rod, and the other end of the movable rod is hinged to the second movable shaft.
[0015] Further, a pressure sensor is arranged at the bottom of the inner cavity of the circular groove.
[0016] Further, the moving rod has a cylindrical structure, and the outer diameter of the moving rod is smaller than the inner diameter of the circular groove.
[0017] Further, the distance that the clamping prevention block extends out of the opening groove is greater than the difference between the outer diameter of the moving rod and the inner diameter of the circular groove, so that the clamping prevention block can effectively prevent the moving rod from extending into the circular groove after extending out of the opening groove.
[0018] Further, a group of moving guide rails are symmetrically formed on the opening groove along the moving direction of the clamping prevention block. A clamping block capable of moving on the moving guide rails is arranged at the bottom of the clamping prevention block.
[0019] Further, the moving component includes a threaded rod rotatably installed along the axial direction of the moving rod. A threaded sleeve is sleeved on the threaded rod. A knob is threadedly installed on the horizontal section of the threaded rod extending out of the moving rod.
[0020] Further, a slider is installed on the threaded sleeve. A second sliding groove for the slider to horizontally move is formed on the inner wall of the sliding cavity.
[0021] Further, the slider is connected with a top rod capable of abutting against the clamping prevention block.
[0022] Furthermore, the contact surface between the clamping prevention block and the top rod is an inclined slope.
[0023] Furthermore, the included angle between the inclined plane and the ejector rod is 20-40°, so that the anti-pinch block can slide in a direction perpendicular to the ejector rod.
[0024] Furthermore, two sliders are symmetrically arranged on the threaded sleeve along its circumference, and corresponding second sliding grooves are symmetrically opened on the inner wall of the sliding cavity.
[0025] Furthermore, two opening grooves are symmetrically opened on the moving rod along its circumference, and two anti-pinch blocks corresponding to the opening grooves are arranged in the sliding cavity.
[0026] Compared with the prior art, the utility model has the following beneficial effects:
[0027] (1) In the utility model, a moving rod that can extend out of the elevator door is arranged inside one side of the elevator door. When it is necessary to repair the elevator to prevent the elevator door from closing, the anti-pinch block can be adjusted to extend out of the opening groove of the moving rod, so as to prevent the moving rod from extending into the circular groove of the other side elevator door, and finally play an anti-pinch function.
[0028] (2) Without affecting the normal use of the elevator door, the utility model cleverly reforms the two sides of the elevator door so that when the elevator needs to be maintained, the extended moving rod and anti-pinch block can keep the two sides of the elevator door open, so as to obtain good light during maintenance and promote the process of elevator maintenance.
[0029] (3) The anti-pinch block of the utility model is cleverly arranged in an inclined plane structure, and the anti-pinch block can be extended out of the opening groove through the cooperation with the ejector rod of the moving component.
[0030] (4) The elevator door with anti-pinch function of the utility model can be applied to various conventional elevator structures, and there is no need to build additional anti-pinch measures during maintenance, which greatly improves the maintenance efficiency.

[0068] The pushing assembly 4 includes a driving member 43 (hydraulic cylinder), a telescopic rod 42 (hydraulic telescopic rod), two movable shafts (a first movable shaft 44 and a second movable shaft 45), a movable rod 41 and a moving rod 3. The driving member 43 is arranged in the cavity of the first elevator door 1, and a telescopic rod 42 is fixedly installed at the output end of the driving member 43. A first movable shaft 44 is fixedly installed on the side wall of the bottom of the telescopic rod 42 close to the second elevator door 2, and a movable rod 41 is movably clamped in the first movable shaft 44; the other end of the movable rod 41 is movably clamped with a second movable shaft 45, and the second movable shaft 45 is fixedly installed on the moving rod 3.
[0069] A circular groove 21 is formed on the side wall of the second elevator door 2 close to the moving rod 3, and a sensor is further arranged at the bottom of the inner cavity of the circular groove 21. When the moving rod 3 enters the circular groove 21 formed on the second elevator door 2 and thus contacts the sensor, the first elevator door 1 and the second elevator door 2 can move relative to each other at this time, so as to close.
[0070] Sliding mechanisms are arranged on the opposite sides of the moving rod 3. The sliding mechanisms include two first sliding grooves 12, and the two first sliding grooves 12 are respectively formed in the inner cavity of the first elevator door 1, and the two first sliding grooves 12 are symmetric with each other. The inner cavities of the two first sliding grooves 12 are slidably clamped with moving rod sliders 33, and the opposite side walls of the two moving rod sliders 33 are connected with the moving rod 3. In this setting, the installation position and composition of the sliding mechanism are determined.
[0071] On opposite side walls of the moving rod 3, rectangular opening grooves 31 are formed. At one end of the moving rod 3 away from the first elevator door 1, a knob 65 is provided. A threaded rod 61 is fixedly connected to the knob 65. The threaded rod 61 movably penetrates through the moving rod 3. A threaded sleeve 62 is meshingly installed on the threaded rod 61. Moving mechanisms are arranged at both ends of the threaded sleeve 62. In this setting, it is ensured that when the knob 65 is rotated, the knob 65 can drive the threaded rod 61 to rotate.
[0072] The moving rod 3 is parallel to the circular groove 21, and the moving rod 3 is movably inserted into the circular groove 21. Two symmetrically arranged opening grooves 31 are formed on the moving rod 3. Two symmetrically arranged moving guide rails 311 are arranged in the inner cavities of the two opening grooves 31. Anti-pinch blocks 5 are arranged above the two moving guide rails 311. The two anti-pinch blocks 5 are symmetric to each other. This setting ensures that the anti-pinch blocks 5 can move horizontally.

[0074] When maintenance is required, the first elevator door 1 and the second elevator door 2 need to be in an open state. At this time, control the hydraulic cylinder to drive the driving telescopic rod 42 to move, so as to drive the angle of the movable rod 41 to change, and then drive the moving rod 3 to move horizontally on the first sliding groove 12 until the moving rod 3 extends out. After extension, the staff rotates the knob 65 arranged on the moving rod 3, so that the knob 65 can drive the threaded rod 61 to rotate. When the threaded rod 61 rotates, it will be able to drive the threaded sleeve 62 to move horizontally with the assistance of the second sliding groove 321 and the slider 63. When the slider 63 moves, it will be able to drive the push rod 64 to move. The two anti-pinch blocks 5 can be pushed out through the push rod 64. Thus, when the first elevator door 1 and the second elevator door 2 need to be closed, the anti-pinch blocks 5 cannot be inserted into the circular groove 21, playing the anti-pinch function of the elevator door in this embodiment.
[0075] The above description of the embodiments is to enable those of ordinary skill in the art to understand and use the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative efforts. Therefore, the present utility model is not limited to the above embodiments, and all improvements and modifications made by those skilled in the art without departing from the scope of the present utility model according to the disclosure of the present utility model should be within the protection scope of the present utility model.
