[0027] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0028] It should be noted that the embodiments and features and technical solutions in the embodiments in the present application can be combined with each other without conflict.

[0029] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0030] Embodiment, please refer to Figures 1-5 A small-tonnage elevator car includes a car body 1, both sides of the car body 1 are provided with air exchange openings, and a filter structure 2 is arranged between each air exchange opening and the car body 1, the filter structure 2 includes a support frame 201 inserted with a heat dissipation opening, a filter screen body 202 is arranged at the middle part of the support frame 201, and two grooves 203 are formed in the support frame 201;

[0031] A threaded hole in communication with the groove 203 is also formed in the support frame 201, a threaded rod 207 is threadedly connected in the threaded hole, one end of the threaded rod 207 extends to the outside of the car body 1 and is fixedly connected with a chuck 208, a clamping groove 209 is formed in the bottom of the chuck 208, a stop lever 3 is inserted into the inner wall of the clamping groove 209, and one end of the stop lever 3 is fixedly connected with the car body 1, rotating the threaded rod 207 makes the chuck 208 rotate and stand up, thereby making the clamping groove 209 separate from the stop lever 3, so that the fixation of the support frame 201 is released, the disassembly of the support frame 201 and the support frame 201 is more convenient, so as to facilitate cleaning, and the maintenance personnel can operate in the car body 1, which is safer.

[0032] Further, a protrusion is arranged on the outer circumferential side of the inner side of the support frame 201, and the protrusion part is in contact with the inner wall of the car body 1, so as to play a limiting role on the support frame 201.

[0033] Further, the chuck 208 is in contact with the car body 1 on one side of the support frame 201, and the distance between the chuck 208 and the support frame 201 is the shortest when the chuck 208 is horizontally arranged. By relying on the friction between the support frame 201 and the car body 1, the chuck 208 can be assisted to limit the rotation of the chuck 208 and the threaded rod 207.

[0034] Further, the bottom of the chuck 208 is fixedly provided with a second counterweight 211, and the second counterweight 211 is located on the side of the chuck slot 209 away from the threaded rod 207. The second counterweight 211 can counterbalance the end of the chuck 208 away from the threaded rod 207, so that the end has a downward rotating trend, thereby improving the stability of the chuck slot 209 and the insertion of the stop rod 3.

[0035] Further, the recess 203 is provided with a rotating disc 204, and the rotating disc 204 is fixedly connected to the end of the threaded rod 207 away from the chuck 208. The rotating disc 204 is arranged to facilitate the rotation of the threaded rod 207.

[0036] Further, the rotating disc 204 and the recess 203 are circularly arranged, which facilitates the rotation of the rotating disc 204.

[0037] Further, the rotating disc 204 is provided with a folding handle 205 on the side away from the threaded rod 207, which facilitates the rotation of the rotating disc 204.

[0038] Further, the outer surface of the car body 1 is provided with a protective member on both sides, and the position of the protective member corresponds to the position of the heat dissipation port.

[0039] Further, the protective member is a grid-shaped protective frame 101, which is fixedly installed on the outer side of the car body 1. The position of the grid-shaped protective frame 101 corresponds to the position of the heat dissipation port, and the grid-shaped protective frame 101 can protect the heat dissipation port, making it safer to remove the support frame 201.

[0040] The use process of the small-tonnage elevator car is as follows:

[0041] When the support frame 201 is taken out, the two folding handles 205 are held and rotated by ninety degrees, the folding handles 205 drive the threaded rod 207 to rotate through the rotating disc 204, the threaded rod 207 drives the chuck 208 to rotate and stand up, so that the clamping groove 209 is separated from the insertion of the stop lever 3, the chuck 208 moves away from the support frame 201 in the process of rotating and standing up, and the folding handle 205 is pulled outward, so that the support frame 201 can be taken out from the heat dissipation port, after the filter screen body 202 is cleaned, the support frame 201 is inserted into the heat dissipation port, the folding handle 205 is reversely rotated to make the chuck 208 rotate to the horizontal, so that the clamping groove 209 is inserted with the stop lever 3, the chuck 208 moves to the direction of the support frame 201 in the process of rotating and standing up and contacts the support frame 201 and the car body 1, so that the convex part of the chuck 208 and the support frame 201 is clamped on the car body 1 under the action of the threaded rod 207, so that the installation can be completed.

[0042] In the present application, unless otherwise clearly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected or in communication with each other; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] Obviously, the above-described embodiments are only a part of the embodiments of the present application, not all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
