Description

Technical Field

[0001] This utility model relates to the field of escape lock technology, specifically a lever-type escape lock cover. Background Technology

[0002] A lever-type escape lock is a hardware device installed on escape doors at safety exits or emergency exits. In an emergency, people only need to press the lever to open the lock, facilitating the rapid evacuation of large numbers of people. It mainly consists of a lock seat and a lever. The lock seat includes a base, a lock cover, and a locking tongue mechanism.

[0003] Existing lever-type escape locks typically contain two lock covers, one with a latch groove and the other without, thus requiring the production of two different lock covers, which increases production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a lever-type escape lock cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lever-type escape lock cover, comprising a cover body, a notch on one side of the cover body, and a latch groove on the other side of the cover body. A blocking plate is detachably installed inside the latch groove. A slot is provided on the inner side of the cover body. A locking block that cooperates with the slot is symmetrically provided on the outer side of the blocking plate. A baffle is provided on one side of the blocking plate. A recessed portion that matches the baffle is provided on the edge of the latch groove.

[0006] As a preferred embodiment of this utility model, a sealing frame is sleeved on the outer side of the blocking plate, and a sealing groove that cooperates with the sealing frame is provided on the recessed part.

[0007] As a preferred embodiment of this utility model, a sealing strip is provided at the bottom of the lock cover body.

[0008] As a preferred embodiment of this utility model, one side of the card block is provided with an inclined surface.

[0009] In a preferred embodiment of this utility model, the size of the baffle is larger than the size of the locking tongue groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the blocking plate, baffle, locking block and locking groove, this utility model can meet different usage needs by producing only one type of lock cover body with locking tongue groove, without the need to produce different types of lock cover bodies, thereby reducing production costs, simplifying inventory, avoiding stockpiling or shortages, reducing capital occupation, and the setting of sealing frame and sealing groove can seal the lock cover body and the baffle, preventing external impurities from entering the lock cover body through the locking tongue groove.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 7This utility model provides a technical solution: a lever-type escape lock cover, including a cover body 1, made of aluminum alloy to ensure sufficient structural strength; a notch 4 on one side of the cover body 1 to facilitate the connection of an external lever with the latch mechanism inside the cover body 1 to drive the latch action; and a latch groove 5 on the other side of the cover body 1 to facilitate the latch extension outside the cover body 1. A blocking plate 11 is detachably installed inside the latch groove 5. The blocking plate 11 and the baffle 2 are used to seal the latch groove 5, so that only one cover body 1 with a latch groove 5 needs to be produced, eliminating the need for... Different types of lock cover bodies 1 are produced to reduce production costs, simplify inventory, avoid stockpiling or shortages, and reduce capital occupation. The inner side of the lock cover body 1 is provided with a slot 7, and the outer side of the blocking plate 11 is symmetrically provided with a locking block 6 that cooperates with the slot 7. The locking block 6 cooperates with the slot 7 to fix the blocking plate 11 on the lock cover body 1. A baffle 2 is provided on one side of the blocking plate 11. The baffle 2, the blocking plate 11 and the locking block 6 are made of plastic and are integrally injection molded. The edge of the lock tongue groove 5 is provided with a recess 8 that matches the baffle 2. The recess 8 is used to accommodate the baffle 2 so that the baffle 2 does not protrude from the outer side of the lock cover body 1.

[0021] The outer side of the blocking plate 11 is fitted with a sealing frame 10, which is made of rubber. The recessed part 8 is provided with a sealing groove 9 that cooperates with the sealing frame 10. The sealing frame 10 and the sealing groove 9 cooperate to seal the baffle 2 and the lock cover body 1, preventing external impurities from entering through the lock tongue groove 5.

[0022] The bottom of the lock cover body 1 is provided with a sealing strip 3. The sealing strip 3 is made of rubber and is used to seal the lock cover body 1 and the base to prevent external dust from entering through the gap between the lock cover body 1 and the base.

[0023] One side of the card block 6 has a bevel, which makes it easier for the card block 6 to be inserted into the card slot 7.

[0024] The size of the baffle 2 is larger than the size of the locking tongue groove 5, so that the baffle 2 cannot pass through the locking tongue groove 5.

[0025] Specifically, if the latch groove 5 is needed, take a tool and push the blocking plate 11 through the notch 4 to separate the blocking plate 11 from the lock cover body 1. At this time, the latch groove 5 is no longer blocked. If the latch groove 5 is not needed, align the blocking plate 11 with the latch groove 5 and press it in. The locking block 6 is inserted into the locking groove 7 to fix the blocking plate 11. The baffle 2 and the lock cover body 1 press the sealing frame 10 tightly so that the sealing frame 10 has a good sealing effect and prevents external impurities from entering the lock cover body 1 through the latch groove 5. Depending on the actual situation, choose whether to install the blocking plate 11.
