Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In this embodiment: referring to fig. 1 and 2, for the utility model discloses an access door of elevator car, including welt 1, welt 1 offers the holding tank 11 that is used for holding the elevator circuit, and the opening part of holding tank 11 is provided with constant head tank 12, and constant head tank 12 department inlays and is equipped with access door body 2, and the both sides that access door body 2 is relative are provided with the joint subassembly that restriction access door body 2 breaks away from constant head tank 12.

Referring to fig. 3 and 4, the clamping assembly includes two clamping bars 3 disposed opposite to each other, and an elastic member 4 connected between the two clamping bars 3.

Wherein, access door body 2 is provided with spout 22, and two joint poles 3 all are located spout 22 and along the length direction and the spout 22 sliding connection of spout 22, and welt 1 is provided with joint groove 13 respectively in the both sides that spout 22 is relative, and two joint grooves 13 and spout 22 are on same straight line. When needs are in the constant head tank 12 with the locking of access door body 2, two joint poles 3 of opposite direction slip make two joint poles 3 run through access door body 2 and carry out the joint with joint groove 13 to spacing in constant head tank 12 (refer to figure 2) with access door body 2, access door body 2 can not deviate from in constant head tank 12.

In addition, the elastic member 4 is specifically a spring having elasticity. The spring is located between two joint rods 3, and two ends of the spring are respectively fixed at one end of two joint rods 3 far away from the joint groove 13. When the access door body 2 is locked in the positioning groove 12, the spring is in a normal state; when the elevator needs to be maintained, the two clamping rods 3 are separated from the clamping grooves 13 through the compression springs, so that the purpose of opening the access door body 2 and maintaining the elevator is achieved. In order to prevent the two clamping rods 3 from compressing the spring, the spring inclines to one side, a telescopic sleeve 5 which can be telescopic is connected between the two clamping rods 3, and the spring is sleeved on the periphery of the sleeve.

For the convenience of sliding the clamping rod 3, the clamping rod 3 is in a round rod shape, a handle 31 is fixedly arranged at one end of the clamping rod 3 close to the spring, and the handle 31 is perpendicular to the clamping rod 3. Since the handle 31 occupies a relatively large space, in order to store the handle 31, in the present embodiment, the first storage groove 23 and the second storage groove 24 for storing the handle 31 are provided at one side of the sliding groove 22, and two first storage grooves 23 and two second storage grooves 24 are provided. Wherein, the two second accommodating grooves 24 are located between the two first accommodating grooves 23, and the distance between the adjacent first accommodating grooves 23 and the second accommodating grooves 24 is greater than or equal to the groove depth of the clamping groove 13. When the access door body 2 is in the locked state, the handle 31 can be received in the first receiving groove 23 by rotating the handle 31; when the access door body 2 needs to be detached from the lining plate 1, the two clamping rods 3 are slid to compress the spring between the two clamping rods 3, so that the clamping rods 3 are separated from the clamping grooves 13, and the handle 31 is rotated to store the handle 31 in the second storage groove 24.

One side of joint pole 3 is provided with sliding block 32, and sliding block 32 and handle 31 are located the relative both sides of spout 22 respectively, and access door body 2 is provided with the gliding guide way 25 of confession sliding block 32, and guide way 25 communicates with each other with spout 22. In this embodiment, the guide groove 25 is a dovetail groove, and the sliding block 32 is adapted to the guide groove 25. The clamping rod 3 is provided with a sliding block 32, and the access door body 2 is arranged in the guide groove 25 matched with the sliding block 32, so that the sliding of the clamping rod 3 is facilitated to be guided.

Referring to fig. 1 and 2, a groove 21 is formed in the surface of the access door body 2 located on the outer side, and a cover plate 6 matched with the groove 21 is embedded in the groove 21. Wherein, spout 22, first groove 23, the second of accomodating is accomodate groove 24 and is all seted up in the bottom of recess 21, inlays at recess 21 and establishes apron 6, is favorable to hiding joint pole 3, spring etc. that are located spout 22, can prevent in dust etc. gets into spout 22. In addition, one side of apron 6 is articulated to be set up in access door body 2, and the surface that apron 6 is located the outside is inwards sunken to be provided with the portion of gripping 61, through setting up the portion of gripping 61, is favorable to elevator maintainer's accessible to hold the portion of gripping 61, opens apron 6 of recess 21 department.

The implementation principle of the embodiment is as follows: when the access door body 2 needs to be opened to overhaul an elevator, the cover plate 6 is firstly opened through the holding part 61, so that the two clamping rods 3 are slid through the handle 31, the two clamping rods 3 are mutually close to each other and compress the spring between the two clamping rods 3, one end of each clamping rod 3 entering the clamping groove 13 is separated from the clamping groove 13, and finally the access door body 2 is taken down from the lining plate 1; because the utility model discloses opening of access door need not additionally with the help of other instruments, so can not take place the elevator maintainer and forget to take the instrument and lead to the problem of unable access door of opening, have the effect of being convenient for open the access door.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
