Description

Extremely simple structure spring lock

Technical Field

The utility model relates to a tool to lock especially relates to an extremely simple structure hits lock.

Background

In some families with pets or children, fence doors are installed at some doors to isolate dangerous places, and the fence doors for entrance and exit are generally closed and fixed by using a latch. The spring used inside the spring lock is used for locking more, so that the spring is out of work after frequent opening and closing or long-time use, and therefore the door lock needs to be replaced at intervals, which not only causes inconvenience in use, but also easily causes unnecessary economic loss due to the fact that the damaged door lock is not replaced in time.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide a simple structure spring lock, which can prolong the service life and reduce the cost.

In order to achieve the purpose, the technical proposal adopted by the utility model is that,

a kind of very simple structure bumping lock, including the fence door 1, the fence door 1 includes fixed door and movable gate, the fixed door is fixed on the wall, the movable gate is mounted to one side of the fixed door, open to the outside; the mounting seat 7 is installed to the outside face of fixed door, is connected with lock seat 3 on the mounting seat 7, is connected with lock core 2 on the lock seat 3, and fixed plate 6 is installed to the outside face of dodge gate, is connected with set bar 5 on the fixed plate 6, and set bar 5 and lock core 2 cooperate.

The lock bolt 5 is a horizontal round rod, one end of the round rod is fixed on the outer side plate surface of the movable door through a fixing plate 6, and the other end of the round rod is horizontally suspended.

The lock seat 3 is a U-shaped sleeve, two top ends of the U-shaped sleeve are fixedly arranged on the fixed door through a mounting seat 7, and a positioning shaft 4 is vertically arranged on two parallel plates of the U-shaped sleeve; the lock core 2 is a large circular ring which is arranged between two parallel plates of the lock base 3 through a positioning shaft 4.

The position of the positioning hole for installing the positioning shaft 4 on the lock base 3 requires that when external force is not applied, the lock core 2 can always keep a vertical and vertical state in the lock base 3 through the self gravity of the lock core under the support of the positioning shaft 4, a distance larger than the diameter of the lock bolt 5 is reserved, and the distance between the positioning shaft 4 and the bottom of the U-shaped sleeve of the lock base 3 cannot be larger than the radius of the lock core 2.

The utility model has the advantages that:

the utility model discloses simple structure, convenient to use. The lock core 2 keeps a vertical state in the lock seat 3, and when the lock bolt 5 enters the lock core 2, the lock core 2 resets by utilizing the self gravity to lock the fence door. The utility model discloses in not using the elastic component, not involving the problem of inefficacy, long service life.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the very simple structure latch includes a barrier door 1, the barrier door 1 includes a fixed door and a movable door, the fixed door is fixed on the wall, the movable door is installed on one side of the fixed door and is opened to the outside; the mounting seat 7 is installed to the outside face of fixed door, is connected with lock seat 3 on the mounting seat 7, is connected with lock core 2 on the lock seat 3, and fixed plate 6 is installed to the outside face of dodge gate, is connected with set bar 5 on the fixed plate 6, and set bar 5 and lock core 2 cooperate.

The utility model discloses a theory of operation does:

when the lock bolt 5 applies an external force to the lock cylinder 2 to approach a fixed door, the lock cylinder 2 rotates around the positioning shaft 4, and the distance between the positioning shaft 4 and the mounting seat 7 can provide enough space for the rotation of the lock cylinder 2, so that the smooth rotation of the lock cylinder 2 is ensured; the set bar 5 is through the lock core 2 after, and the lock core 2 utilizes self gravity to get back to vertical state, when the dodge gate attempted direct outside opening, and the outside power is exerted to lock core 2 to set bar 5, and lock core 2 rotates around location axle 4 because the distance of location axle 4 and the U type cover bottom of lock seat 3 is less than the radius of lock core 2, and the great circle of lock core 2 encircles and is blocked after location axle 4 rotates certain angle to this locking of accomplishing the dodge gate is fixed.

When the door is opened, the movable door is slightly pushed inwards, the lock cylinder 2 is lifted by hand, and the lock bolt 5 can be easily separated from the lock cylinder 2.

The foregoing description is only of the preferred embodiments of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
