Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and in particular relates to a new type of lock. Background Art

[0002] A lock is a device that is used to fix or seal something. There are many types of locks, and their effects vary.

[0003] Most of the existing locks are developed for long-term fixation. They are equipped with corresponding keys. The locks cannot be unlocked directly without the keys. However, in some occasions where only short-term fixation is required, the use of these locks is inconvenient.

[0004] Specifically, for example, in the field of electrical automation, a lock for fixing a door panel is provided on the cabinet body of an electrical cabinet. During the maintenance and inspection of the electrical cabinet, the operator sometimes needs to leave temporarily, and the door panel needs to be locked and fixed. When the operator comes back, the door panel needs to be unlocked again with a key. When a large number of electrical cabinets need to be repaired, work efficiency will be significantly reduced.

[0005] Therefore, it is necessary to design a lock that can quickly achieve temporary fixation and is more convenient to unlock. Summary of the invention

[0006] At present, there is a lack of a lock that can quickly achieve temporary fixation and is relatively convenient to unlock. The following utility model is now proposed:

[0007] The lock member is a key element in the lock mechanism, and the second locking member is a key element in the lock mechanism, and the key element is a key element in the lock mechanism.

[0008] Furthermore, it also includes a mounting seat fixedly installed in the shell, the mounting seat is provided with a mounting sleeve, the mounting sleeve is provided with a reset rod and a spring sleeved on the outside of the reset rod, the reset rod is provided with an annular plate that presses against the end of the spring, and the other end of the spring presses against the inner side of the mounting sleeve.

[0009] Furthermore, a transmission head is provided at the end of the reset rod, and a through hole is provided on the transmission head for the transmission rod to be inserted.

[0010] Furthermore, a movably inserted interlocking rod is provided in the housing, an interlocking main board is provided at the side of the other end of the reset rod, and an oblong hole is provided on the interlocking main board for inserting the interlocking rod to prevent the reset rod from moving.

[0011] Furthermore, the ends of the interlocking main plate and the interlocking rod are respectively provided with a transverse plate and a pulling plate for pulling the interlocking main plate and the interlocking rod outward.

[0012] Furthermore, a stopper located above the clamping slot is provided on the side of the clamping joint to increase the stability of the matching between the clamping joint and the clamping slot.

[0013] Furthermore, a connecting shaft is provided in the shell, and a connecting sleeve movably mounted on the connecting shaft is provided on the first locking plate and the second locking plate.

[0014] The utility model proposes a new type of lock, which does not require the use of keys or other tools for unlocking and locking. It is mainly suitable for some equipment that requires long-term maintenance. When the operator needs to leave temporarily, the lock can be used to temporarily fix the equipment. When the equipment is to be repaired again, the lock can be unlocked. It is more convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with embodiments.

[0021] Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein. In addition, the terms "include" and "have" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. 7

[0023] like Figure 1-Figure 3 As shown, it is a preferred embodiment of the utility model, a new type of lock, including a shell 1, a lock plate 2, a first locking plate 3, and a second locking plate 4. A lock groove 12 is provided on one side of the shell 1, a lock hole 21 is provided on the lock plate 2, and a connecting shaft 11 is provided in the shell 1. The first locking plate 3 and the second locking plate 4 are provided with a connecting sleeve 34 movably sleeved on the connecting shaft 11, that is, the two locking plates are rotatably installed in the shell 1; a lock head 31 extending from the lock groove 12 is provided on the side of the first locking plate 3, and the lock head 31 matches the lock hole 21. A clamping joint 32 and a stopper 33 located on the side of the clamping joint 32 are provided at the bottom of the first locking plate 3; a clamping groove 41 matching the clamping joint 32 is provided at one end of the second locking plate 4, and a horizontally extending transmission rod 42 is provided at the other end of the second locking plate 4, and a vertical reset rod 5 is transmission-connected to the end of the transmission rod 42, and the reset rod 5 is elastically installed in the shell 1.

[0024] After the lock plate 2 cooperates with the lock head 31, the clamping joint 32 on the first locking plate 3 cooperates with the clamping groove 41 of the second locking plate 4. At this time, after the lock plate 2 is pulled outward, when the force on it is small, the lock head 31 will not separate from the lock plate 2, so as to achieve the purpose of locking the lock plate 2. When the lock plate 2 is subjected to a large force, the first locking plate 3 rotates outward together with the lock head 31. During this process, the clamping joint 32 separates from the clamping groove 41, and the second locking plate 4 tilts to one side and is then driven by the reset rod 5 to return to the initial position. After the lock head 31 rotates to completely separate from the lock hole 21, the lock plate 2 can be pulled out therefrom. At this time, the first locking plate 3 as a whole tilts toward the lock groove 12, and the clamping joint 32 separates from the clamping groove 41 and is located at the side.

[0025] When the lock plate 2 is reinserted into the lock slot 12, the lock plate 2 pushes the first lock plate 3 to rotate inward, and the clamping joint 32 pushes the end of the clamping slot 41 of the second lock plate 4 to rotate downward. The transmission rod 42 tilts upward and drives the reset rod 5 to elastically displace upward until the clamping joint 32 completely enters the upper part of the clamping slot 41. Then the reset rod 5 elastically resets and drives the second lock plate 4 to reset. The clamping slot 41 is matched with the clamping joint 32 again to achieve locking of the lock plate 2.

[0026] In this embodiment, the difference between the lock and the general lock is that the fixation between the lock plate 2 and the lock head 31 is not completely firm, and the lock of the two can be released by applying a large external force without the aid of other tools. Compared with general locks, this lock is mainly used in some occasions where the equipment only needs to be fixed for a short time, or used in conjunction with other traditional locks.

[0027] In this embodiment, the lock further comprises a mounting seat 51 fixedly mounted in the housing 1, a mounting sleeve 52 being provided on the mounting seat 51, a reset rod 5 and a spring 53 sleeved on the outside of the reset rod 5 being provided inside the mounting sleeve 52, an annular plate 55 being provided on the reset rod 5 to press against the end of the spring 53, the other end of the spring 53 being pressed against the inside of the mounting sleeve 52, a transmission head 54 being provided at the bottom of the reset rod 5, a through hole being provided on the transmission head 54 for inserting the transmission rod 42, and after the second locking plate 4 is rotated, the reset rod 5 is driven to elastically move in the vertical direction through the transmission rod 42.

[0028] In this embodiment, a movably inserted interlocking rod 6 is further provided in the shell 1, and an interlocking main board 61 is provided at the top side of the reset rod 5. The interlocking main board 61 is provided with an oblong hole 64 for inserting the interlocking rod 6 to prevent the reset rod 5 from moving. A horizontal plate 62 and a pulling plate 63 are respectively provided at the ends of the interlocking main board 61 and the interlocking rod 6 for pulling the interlocking main board 61 and the interlocking rod 6 outward.

[0029] Only after the interlocking rod 6 is pulled outward from the interlocking main board 61, can the interlocking main board 61 move in the vertical direction, and then the lock of the lock plate 2 and the lock head 31 can be released. The interlocking rod 6 is mainly used in some occasions where it is necessary to prevent the operator from accidentally pulling the lock plate 2. In addition, the operator can also directly pull the interlocking main board 61 to release the lock between the lock head 31 and the lock hole 21 without pulling the lock plate 2 hard, thereby reducing the wear between the lock plate 2 and the lock head 31.

[0030] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
