Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a triangular key for an elevator. Background Art

[0002] When an elevator malfunctions or is being installed, it is sometimes necessary to open the elevator floor door or car door and keep it open. In such cases, elevator staff often use a triangular key to open the elevator door and then randomly search for objects such as screwdrivers or expansion bolts to prevent the floor door or car door from closing. Because the objects used are not dedicated door blockers, the door blocking effect is not very reliable. Sometimes the door will reclose when it is touched or vibrated. This situation poses certain risks to certain elevator operations. For example, when an elevator staff member is carrying an object into the shaft and the door suddenly closes, the elevator staff member may turn around to prevent the door from closing due to the abnormal door behavior, which may cause the carried objects to collide with others, causing damage to the carried objects, or even causing the person to fall or fall into the shaft due to hasty steps.

DETAILED DESCRIPTION

[0021] The utility model object of the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation methods of the utility model are not limited to the following embodiments.

[0022] like Figure 1 and 2 As shown, a triangular key for an elevator includes a key head 1, a first elastic bending part 2, a second elastic bending part 3, a first anti-slip pad 4, and a second anti-slip pad 5. The upper end of the key head 1 is welded to the left end of the first elastic bending part 2, and the right end of the first elastic bending part 2 is welded to the right end of the second elastic bending part 3. The lower end of the key head 1 passes through the limiting hole 303 of the second elastic bending part 3. The first anti-slip pad 4 is attached to the top surface of the first elastic bending part 2, and the right end of the first anti-slip pad 4 covers the intersection of the first elastic bending part 2 and the second elastic bending part 3. The second anti-slip pad 5 is attached to the bottom surface of the second elastic bending part 3, and the first anti-slip pad 4 and the second anti-slip pad 5 are connected.

[0023] The key head 1 is used to insert the triangular hole into the triangular lock cylinder to unlock the door. Both the first and second elastic bent parts 2 and 3 are made of spring steel, allowing for easier downward pressure when the triangular key is used to block the door, creating a smaller wedge slope and facilitating insertion into the door gap. Once inserted, the rebound of the first and second elastic bent parts 2 and 3 tightens the door. Both the first and second anti-slip pads 4 and 5 are made of rubber to increase friction.

[0024] like Figure 3 As shown, the first elastic bending member 2 includes a pressing plate 201 and a bent connecting portion 202. A retaining groove is provided at the top of the key head 1, and the lower end of the bent connecting portion 202 is embedded in the retaining groove. The lower end of the bent connecting portion 202 is welded to the top of the key head 1. The top of the bent connecting portion 202 is connected to the left end of the pressing plate 201, and the right end of the pressing plate 201 is welded to the right end of the second elastic bending member 3. The first anti-slip pad 4 is covered on the top of the pressing plate 201 by bolts or glue.

[0025] like Figure 3As shown, the second elastic bending member 3 includes a positioning plate 301 and a bending portion 302. The positioning plate 301 is provided with a limiting hole 303, which is elliptical. The lower end of the key head 1 passes through the limiting hole 303, and the key head 1 can swing left and right in the limiting hole 303. The right end of the positioning plate 301 is connected to the right end of the first elastic bending member 2. The second anti-slip pad 5 is covered on the bottom of the positioning plate 301 by bolts or glue. The second anti-slip pad 5 is located on the right side of the positioning hole. The left end of the positioning plate 301 is connected to the upper end of the bending portion 302, and the lower end of the bend is facing the side away from the first elastic bending member 2.

[0026] like Figure 2 As shown, the key head 1 comprises a connecting cylindrical portion 101, a transition connecting portion 102, and a keyhole portion 103. The connecting cylindrical portion 101 is cylindrical, with a retaining groove at its top. The bent connecting portion 202 of the first elastic bending member 2 is inserted into the retaining groove and welded to the retaining groove. The lower end of the connecting cylindrical portion 101 passes through the retaining hole 303 of the second elastic bending member 3 and connects to the upper end of the transition connecting portion 102. The lower end of the transition connecting portion 102 is connected to the top of the keyhole portion 103, and the bottom of the keyhole portion 103 is provided with a triangular hole.

[0027] like Figure 4 As shown, the first anti-slip pad 4 includes an anti-slip plate 401 and a stopper 403. The anti-slip plate 401 is mounted on the first elastic bending member 2 using bolts or glue. The anti-slip plate 401 is connected to the stopper 403, which is located at the junction of the first elastic bending member 2 and the second elastic bending member 3. The anti-slip plate 401 is provided with multiple anti-slip grooves, with a ridge 402 located between adjacent anti-slip grooves.

[0028] The second anti-skid pad 5 is similar in structure to the anti-skid plate 401. The anti-skid plate 401 is provided with anti-skid grooves, and a ridge 402 is provided between two adjacent anti-skid grooves. The right end of the second anti-skid pad 5 is connected to the limiting portion 403 of the first anti-skid pad 4.

[0029] Unlocking principle: By embedding the triangular hole on the key head 1 into the triangular lock core, the handle formed by the first elastic bending part 2 and the second elastic bending part 3 can be used to twist the lock core to rotate with little effort, thereby completing the unlocking.

[0030] Explanation of the door-blocking principle: The first elastic bending part 2, the second elastic bending part 3, the first anti-slip pad 4 and the second anti-slip pad 5 form a door wedge. When the elevator's triangular key is in use, by pressing the first elastic bending part 2, a smaller door wedge angle can be obtained, making it easier to insert it into the door gap. At the same time, because the first elastic bending part 2 and the second elastic bending part 3 both have a certain elasticity, the elevator door obtains a greater supporting force. Under the interaction force, the bottom of the door wedge (that is, the first elastic bending part 2 and the second elastic bending part 3) obtains a greater vertical separation, so that the whole obtains greater friction and the door-blocking effect is better. After the door-blocking function of the elevator's triangular key is completed, the first elastic bending part 2 is pressed again to reduce the door wedge angle and push the elevator door backward, so that the door wedge obtains a larger gap, and the elevator's triangular key can be more conveniently removed.

[0031] The above specific implementation methods are preferred embodiments of the present invention and cannot limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the scope of protection of the present invention.
