Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment protection, in particular to a handle-equipped padlock latch structure for equipment maintenance interlocking. Background Art
[0002] The protection of equipment is to separate the equipment operation area from the personnel safety area and delimit the operation space of the equipment, so as to ensure that when the equipment is operating normally, personnel will not enter the equipment operation space by mistake, threatening the safety of personnel.
[0003] However, when the equipment has problems or malfunctions, in order to repair the equipment, maintenance personnel will inevitably enter the equipment protection through the maintenance door. At this time, if the maintenance personnel are not found and the maintenance door is closed to start the equipment, it is possible that the maintenance personnel are in a place where they are not easily noticed, which will pose a danger to the maintenance personnel; or the maintenance personnel leave midway and the equipment has not been repaired yet, which will cause damage to the equipment. Summary of the Invention
[0004] The utility model mainly solves the deficiencies existing in the prior art, and provides a handle-equipped padlock latch structure for equipment maintenance interlocking, which has the characteristics of compact structure, convenient use and good stability. It solves the problem of abnormal closing of the maintenance door during maintenance. On the premise of not affecting the functions of opening, closing and locking the door, it realizes that after the maintenance personnel open the door, other personnel will not be able to lock the maintenance door, ensuring the personal safety of the maintenance personnel and the safety of the maintenance equipment.
[0005] The above technical problems of the utility model are mainly solved by the following technical solutions:
[0006] A handle-equipped padlock latch structure for equipment maintenance interlocking, including a door and a door frame. A handle is provided on the door. A substrate is provided between the handle and the door. A latch plate that is slidably inserted and limited with the substrate is provided between the substrate and the handle. The latch plate is fixedly connected with the handle. A socket that is slidably inserted with the latch plate is provided on the door frame.
[0007] Preferably, a rear fixing block that is slidably inserted with the latch plate is provided at one end of the substrate, and a front fixing block that is slidably inserted with the latch plate is provided at the other end of the substrate.
[0008] Preferably, lock holes are provided at both ends of the latch plate.
[0009] Preferably, a padlock that is inserted into the lock hole is provided on the lock hole.
[0010] Preferably, the handle has a "concave" shape structure, and the handle is fixedly connected with the latch plate by screws.
[0011] The utility model can achieve the following effects:
[0012] The utility model provides a handle-equipped padlock door latch structure for equipment maintenance interlock, which, compared with the prior art, has the characteristics of compact structure, convenient use and good stability. It solves the problem of abnormal closing of the maintenance door during maintenance. On the premise of not affecting the functions of opening, closing and locking the door, after the maintenance personnel open the door, other personnel will not be able to lock the maintenance door, ensuring the personal safety of the maintenance personnel and the safety of the maintenance equipment. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 is the front view structural schematic diagram of the utility model.
[0014] Figure 2 is the top view structural schematic diagram of the utility model.
[0015] In the figure: door 1, rear fixing block 2, lock hole 3, latch plate 4, handle 5, base plate 6, front fixing block 7, socket 8, door frame 9, padlock 10. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The technical solution of the present utility model will be further specifically described below through embodiments and in conjunction with the drawings.
[0017] Embodiment: As Figure 1 and Figure 2 shown, a handle-equipped padlock door latch structure for equipment maintenance interlock includes a door 1 and a door frame 9. A handle 5 is provided on the door 1, and the handle 5 is in a "concave" shape structure. A base plate 6 is provided between the handle 5 and the door 1, and a latch plate 4 that is slidably inserted and limited with the base plate 6 is provided between the base plate 6 and the handle 5. Lock holes 3 are provided at both ends of the latch plate 4, and a padlock 10 that is inserted into the lock hole 3 is provided on the lock hole 3. The latch plate 4 is fixedly connected to the handle 5, and a socket 8 that is slidably inserted with the latch plate 4 is provided on the door frame 9. One end of the base plate 6 is provided with a rear fixing block 2 that is slidably inserted with the latch plate 4, and the other end of the base plate 6 is provided with a front fixing block 7 that is slidably inserted with the latch plate 4.
[0018] Working principle: When the door 1 is closed, the front side of the handle 5 is in contact with the front fixing block 7, the latch plate 4 is inserted into the socket 8, and the padlock 10 is locked in the lock hole 3 in front of the latch plate 4. When the door 8 needs to be opened, the padlock 10 is opened, the handle 5 is pulled to drive the latch plate 4 to move backward until the rear side of the handle 5 is in contact with the rear fixing block 2. The lock hole 3 at the rear side of the latch plate 4 extends out of the rear fixing block 2, and the lock hole at the front side of the latch plate 4 shrinks into the front fixing block 7. The padlock 10 is locked in the lock hole 3 at the rear side of the latch plate 4, and the handle 5 is pulled to open the door. At this time, the latch plate 4 cannot move back and forth, and the key of the padlock 10 is carried by the maintenance personnel.
[0019] In summary, the handle-equipped padlock latch structure for equipment maintenance interlock has the characteristics of compact structure, convenient use and good stability. It solves the problem of abnormal closing of the maintenance door during maintenance. On the premise of not affecting the functions of opening, closing and locking the door, after the maintenance personnel open the door, other personnel will not be able to lock the maintenance door, ensuring the personal safety of the maintenance personnel and the safety of the maintenance equipment.
