Detailed Description

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

Referring to fig. 1, the elevator triangular key disclosed by the present invention comprises a first sleeve 1, a second sleeve 2 inserted into the first sleeve 1, and a third rod 3 hinged to the bottom of the second sleeve 2; a first key head 4 arranged at the head of the first sleeve 1. The two sleeves are square pipes; the square tube prevents relative slippage of the first sleeve 1 and the second sleeve 2 when a rotational force is applied to the sleeves. The third section of rod 3 comprises two clamping pieces 31 hinged at the bottom ends of the lifting and contracting rods and a connecting block 32 for connecting the two clamping pieces 31 at the lower ends of the two clamping pieces 31; the side of the connecting block 32 is provided with a second key head 5.

Under the normal state, the first sleeve 1 is received in the second sleeve 2, and the third rod 3 is rotated and overlapped with the second sleeve 2 to be received between the two clamping pieces 31. The second key head 5 on the connecting block 32 is used for a lock hole which can be obtained by a person located on the outer surface of the hoistway door.

As shown in fig. 2, for a lock hole which is positioned at the top of an elevator door opening and can not be reached by a person, the second sleeve 2 can be rotated out from the third section rod 3, so that the second sleeve and the third section rod are in a vertical state, the first sleeve 1 is pulled out from the second sleeve 2, and the first key head 4 fixedly connected with the top of the first sleeve 1 is used for opening the lock hole at the top of the elevator door opening; in the state, the third section of rod 3 in the vertical state increases the force arm for screwing, so that the triangular lock is opened more labor-saving. As shown in fig. 3, if the lockhole is too far away from the ground, the height of a maintenance worker is not enough, even if the lockhole is still not enough in the above state, the length of the device can be increased by continuously rotating the third rod 3, the length is the largest when the third rod 3 and the second sleeve 2 are in a straight line, and the maintenance worker can conveniently open the lockhole at the top of the door hole. The device has the advantages that the maintenance worker can conveniently open the existing elevator lock holes at two different positions, the pin holes at the high positions can be opened without a chair or a ladder, and the device is easy to carry; in addition, the arrangement of the two key heads enables the device to open two different types of lock holes.

Preferably, the end of the key head is provided with an external thread and the first sleeve 1 head is provided with an internal thread matching the external thread, screwing the first key head 4 into the first sleeve 1 head. The side of connecting block 32 is seted up with the internal thread that the key head external screw thread matches, and second key head 5 twists into connecting block 32. By manually replacing key heads with different models, the elevator hall door with different models of different producers can be opened, and the door of an electric cabinet can also be opened. And the first key head 4 and the second key head 5 can select two different types, and the two types can be replaced by each other according to actual conditions in the maintenance process. The device has realized dismantling of key head, and when the maintenance elevator, the maintenance workman only need carry this device, takes enough key head can open the lockhole of different models, conveniently carries, and is not restricted to and is used for opening the hoistway door.

When the key head is inserted into the lock hole, the lock hole applies a pushing force to the key head, and in order to prevent the pushing force from being too large, the first sleeve 1 is retracted into the second sleeve 2. Therefore, referring to fig. 2 and 3, a ball plunger 21 is arranged at the joint of the first sleeve 1 and the second sleeve 2, the ball plunger 21 is installed at the bottom end of the first sleeve 1, a through hole is formed in one side wall, close to the top end, of the second sleeve 2, and when the first sleeve 1 is elongated to the longest length, the ball of the ball plunger 21 is clamped into the through hole to achieve clamping. In the recovery, recovery can be achieved by pressing the first sleeve 1 with force.

Further, referring back to fig. 1 and 2, one end of the connecting block 32 close to the sleeve is provided with a straight chamfer 321, so that the third rod 3 and the second sleeve 2 can be conveniently rotated to open and close, the length of the whole device can be properly shortened, and the carrying is convenient. The edge openings of the two clamping pieces 31 are fixedly connected with limiting pieces 322, two ends of the limiting pieces 322 are vertically and fixedly connected with the edges of the two clamping pieces 31, and the limiting pieces 322 are close to the connecting block 32. At this time, the straight chamfer 321 is disposed at an end away from the stopper piece 322. After the second sleeve 2 is inserted into the third rod 3 in a rotating manner, the second sleeve cannot rotate out from the other opening of the third rod 3, so that the device is convenient to store and carry.

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.
