Description

Technical Field

[0001] The utility model relates to the technical field of construction elevator floor doors, in particular to a construction elevator door lock. Background Art

[0002] Construction elevators are common construction equipment that can be used to lift and carry people or materials vertically over a large area. They are construction machinery with a higher probability of accidents.

[0003] Traditional construction elevator landing doors (opening the landing door to enter the construction floor) are fixed with latches, which are often opened by wind loads, human factors, external factors, etc. There are great safety hazards when the construction elevator landing doors on high floors are accidentally opened. Some construction units will use locks to lock the construction elevator landing doors, but it is very cumbersome to unlock them in this case, especially in high-rise buildings. If each construction elevator landing door is equipped with a lock, there will be many corresponding keys, and it will be very cumbersome for the elevator driver to unlock and find the right key when arriving at the corresponding floor.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a construction elevator door lock to ensure the safety performance of the construction elevator.

[0006] The technical solution of the utility model is as follows:

[0007] A construction elevator door lock comprises a locking rod, a latch, a telescopic mechanism, a magnetic switch and a rotating mechanism, wherein the locking rod is arranged on a first mounting surface, and a limiting hole is provided on a side of the locking rod close to the second mounting surface; the latch is arranged on the second mounting surface, and the latch is aligned with the limiting hole; the telescopic mechanism connects the latch; the magnetic switch comprises a magnet arranged on the locking rod, and a contact arranged on the second mounting surface; and the rotating mechanism rotatably connects the locking rod and the first mounting surface.

[0008] The beneficial technical effects of the utility model are as follows:

[0009] (1) The construction elevator door lock in the utility model is provided with a lock rod, a latch and a telescopic mechanism. The telescopic mechanism is driven to plug the latch and the lock rod for locking. The plugging stability is good, and the action is simple and easy to implement, which is conducive to simplifying the structure of the construction elevator door lock. In addition, the locking and unlocking actions are implemented by the telescopic mechanism, and the operation is highly universal. Multiple telescopic structures can be driven in the same way, which is easy to operate. Finally, a magnetic switch and a rotating mechanism are also provided. The magnetic switch can determine whether the lock rod is rotated to the preset angle for plugging the lock rod and the latch, and then determine whether the construction elevator door lock is locked.

[0010] (2) Furthermore, a first lock seat and a second lock seat are provided, and all parts are fixed to the first mounting surface and the second mounting surface through the first lock seat and the second lock seat, thereby simplifying the installation.

[0011] (3) Furthermore, the telescopic mechanism includes a triangular lock and a connecting rod. When the triangular lock is unlocked, the lock tongue of the triangular lock rotates to drive the bolt to move. The triangular lock driving method reduces the possibility of unlocking or locking by mistake. At the same time, the unlocking method is highly universal. Different triangular locks can be unlocked with the same tool, reducing tool management. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiment 1

[0019] Figure 1 The figure shows the internal structure of the construction elevator door lock of the utility model after the cover is hidden. Figure 1 A construction elevator door lock includes a locking rod 6, a latch 3, a telescopic mechanism 2, a magnetic switch 7 and a rotating mechanism 5. The locking rod 6 is arranged on the first mounting surface, and a limiting hole (not shown in the figure) is provided on the side of the locking rod 6 close to the second mounting surface. The latch 3 is arranged on the second mounting surface, and the latch 3 is aligned with the limiting hole. The telescopic mechanism 2 connects the latch 3. By controlling the telescopic mechanism 2, the latch 3 can be driven to move and insert into the limiting hole of the locking rod 6, and the relative position of the first mounting surface and the second mounting surface is fixed. Or the latch 3 can be driven to move away from the limiting hole of the locking rod 6, and the relative movement of the first mounting surface and the second mounting surface is no longer restricted. The magnetic switch 7 includes a magnet 71 arranged on the locking rod 6, and a contact 72 arranged on the second mounting surface. The rotating mechanism 5 rotatably connects the locking rod 6 and the first mounting surface.

[0020] Among them, the magnetic switch 7 can determine whether the locking rod 6 is rotated to the preset angle for the locking rod 6 and the latch 3 to be plugged in, and then determine whether the construction elevator door lock is locked. The magnetic switch 7 is connected to the control system (not shown in the figure) to provide real-time feedback on the locking status. For example, when the operator drives the telescopic mechanism 2 to extend the latch 3, if the magnet 71 in the magnetic switch 7 is close to the contact 72, it can be determined that it is locked. If the magnet 71 in the magnetic switch 7 is far away from the contact 72 and cannot sense each other, it is determined that it is not locked.

[0021] The specific structures of the telescopic mechanism 2 and the rotating mechanism 5 are described below:

[0022] Figure 2 The three-dimensional structure diagram of the construction elevator door lock of the utility model is shown. Figure 1 and Figure 2The telescopic mechanism 2 includes a triangular lock 21 and a connecting rod 23. The lock tongue 22 of the triangular lock 21 is rotatably connected to the connecting rod 23, and the connecting rod 23 is also rotatably connected to the bolt 3. By twisting the triangular lock 21, the lock tongue 22 can be driven to rotate, and the lock tongue 22 rotates to drive the connecting rod 23, and the connecting rod 23 pushes out or pulls back the bolt 3 to unlock or lock. The driving method of the triangular lock 21 reduces the situation of unlocking or locking by mistake, and the unlocking method is highly versatile. Different triangular locks 21 can be unlocked with the same tool, reducing tool management.

[0023] The rotating mechanism 5 includes a rotating shaft 52, and the rotating shaft 52 is connected to the locking rod 6 through a synchronous pin 53. The locking rod 6 can be synchronously rotated by rotating the rotating shaft 52, which simplifies the operation. The rotating mechanism 5 also includes a handle 51, and the handle 51 is connected to the rotating shaft 52 through the synchronous pin 53. The operator can quickly drive the locking rod 6 to rotate by turning the handle 51, which is convenient for on-site operation.

[0024] The specific structure of the first lock seat 1 is described below:

[0025] Please refer to Figure 1 , and also includes a first lock seat 1 arranged on the first mounting surface, and the latch 3, the telescopic mechanism 2 and the magnetic switch 7 are arranged on the first lock seat 1. The latch 3, the telescopic mechanism 2 and the magnetic switch 7 are first installed on the first lock seat 1, and then uniformly fixed on the first mounting surface to simplify the installation. The first lock seat 1 is provided with a cover body 11 and an extension part 12, and the latch 3, the telescopic mechanism 2 and the magnetic switch 7 are arranged in the cover body 11 to enhance the protection performance. The extension part 12 is arranged on the rotation path of the lock rod 6 to limit the rotation angle of the lock rod 6 to prevent the lock rod 6 from excessively rotating and colliding with the magnet 71 and the contact 72.

[0026] The specific structure of the second lock seat 4 is described below:

[0027] Please refer to Figure 1 , and further includes a second lock seat 4 arranged on the second mounting surface, and a lock rod 6 and a rotating mechanism 5 are arranged on the second lock seat 4. The lock rod 6 and the rotating mechanism 5 are first installed on the second lock seat 4, and then uniformly fixed on the second mounting surface, simplifying the installation. A support frame 41 is also arranged on the second lock seat 4, and the support frame 41 is arranged on the rotation path of the lock rod 6. When the lock rod 6 and the bolt 3 are plugged, the support frame 41 supports the lock rod 6 to increase stability.

[0028] The latch pin 3 may be a latch pin 3 of an electromagnetic lock, and the connecting rod 23 pushes the tail rod of the electromagnetic lock to make the latch pin move in and out of the lock rod to lock and unlock.

[0029] The specific workflow of this embodiment is as follows:

[0030] When locking, the operator turns the handle 51, and the handle 51 drives the rotating shaft 52 to rotate, thereby synchronously rotating the lock rod 6. The lock rod 6 is continuously rotated until the lock rod 6 abuts against the extension 12, and the lock rod 6 is still supported by the support frame 41. The triangular lock 21 is twisted, and the lock tongue 22 of the triangular lock 21 rotates to drive the connecting rod 23 to move, and the connecting rod 23 pushes the bolt 3 to insert into the limiting hole of the lock rod 6. At this time, the magnetic switch 7 outputs a contact signal, and the locking is completed.

[0031] When unlocking, the operator twists the triangular lock 21 in the opposite direction, and the lock tongue 22 of the triangular lock 21 rotates to drive the connecting rod 23 to move, and the connecting rod 23 pulls the bolt 3 out of the limit hole. The operator turns the handle 51 in the opposite direction, and the handle 51 drives the rotating shaft 52 to rotate, and then synchronously rotates the lock rod 6 in the opposite direction. At this time, the magnetic switch 7 outputs a separation signal, and the unlocking is completed.

[0032] Embodiment 2

[0033] The structure and working process of the second embodiment are mostly the same as those of the first embodiment, except that the telescopic mechanism 2 is a telescopic motor (not shown in the figure). The operator can drive the latch 3 by pressing the control button of the telescopic motor, which is more convenient to operate. The telescopic length of the telescopic motor can also be flexibly controlled, thereby accommodating greater installation errors and facilitating automatic control.

[0034] It can be seen that the above-mentioned construction elevator door lock is locked by driving the telescopic mechanism 2, plugging the bolt 3 and the locking rod 6. The plug-in stability is good, and the action is simple and easy to implement, which is conducive to simplifying the structure of the construction elevator door lock. In addition, the locking and unlocking actions are realized by the telescopic mechanism 2, and the operation is versatile. Multiple telescopic structures can be driven in the same way, which is easy to operate. Finally, a magnetic switch 7 and a rotating mechanism 5 are also provided. The magnetic switch 7 can determine whether the locking rod 6 is rotated to the preset angle of the locking rod 6 and the bolt 3, and then determine whether the construction elevator door lock is locked.

[0035] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
