Description

A kind of U-shaped mortise lock convenient for locking

Technical field

The present invention relates to lock technology fields, more particularly, to a kind of U-shaped mortise lock convenient for locking.

Background technique

Currently, general U-shape lock, including U-shape lock ring, lock body on the market, lockhole, setting on the inside of lockhole are provided on lock body There is lock pin, the inside of U-shape lock ring lower part straight-bar is evenly distributed with multiple locked grooves, lock ring is inserted in lockhole, and lock pin fastens locked groove Complete locking-in state.Due to having gap between lockhole and lock ring, when lock ring is inserted into lockhole, often there are both ends Lock ring does not accomplish synchronous insertion lockhole, and lock ring is caused to block with lockhole, cause using inconvenience.

Summary of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of U-shaped mortise lock convenient for locking, and structure is simple, easy to use, It not will cause lock ring and the stuck state of lockhole, greatly improve practicability and convenience.

The technical solution adopted by the present invention to solve the technical problems is: a kind of U-shaped mortise lock convenient for locking, including U-shaped Lock ring, lock body are provided with lockhole on the lock body, are provided with lock pin on the inside of the lockhole, U-shape lock ring lower part straight-bar it is interior Side is evenly distributed with multiple locked grooves, and the lockhole includes the first lockhole and the second lockhole, is provided with opening, the U on second lockhole The lower part straight-bar of type lock ring can be placed in second lockhole by the opening, and the lock body is in second lockhole Inside is provided with the limit plate that can be stretched, and the limit plate end is provided with elastic mechanism, original state, the elastic mechanism The limit plate is driven to be inserted in the limit hole on the lock body, when the lower part straight-bar of the U-shape lock ring is pressed against the limit When on plate, the limit plate stress is bounced back in the lock body, when the U-shape lock ring is sticked into second lockhole, the limit Position plate restores to original state.In this way, using when a wherein straight-bar for the U-shape lock ring first can be initially inserted into In one lockhole, the U-shape lock ring is then rotated, another straight-bar on the U-shape lock ring, which is resisted against, described can stretch On the limit plate, the limit plate stress is bounced back in the lock body, when this root straight-bar is totally placed in second lockhole When middle, the limit plate is driven stretching until being inserted into the limit hole on the lock body by elastic mechanism, makes the second lock The opening in hole is closed.

In above-mentioned technical proposal, it is preferred that the elastic mechanism is spring, and the quantity of the spring is 2.It is respectively set In the two sides of the limit plate, it can make the sliding of limit plate will not be crooked, more smoothly.

In above-mentioned technical proposal, it is preferred that the limit board ends have thickness difference, and the thickness close to lock body center is less than Thickness on the outside of lock body.In this way, it is described U-shaped so as to open to be effectively prevented limit plate described in slide outside Lock ring is sealed with second lockhole.

In above-mentioned technical proposal, it is preferred that when locking states, the lower part straight-bar of the limit plate and the U-shape lock ring The shortest distance is 1-2mm.In this way, the limit plate can be resisted against the U-shape lock when external force pushes the limit plate On ring, prevents the limit plate stress from bouncing back, guarantee the safety of U-shape lock.

In above-mentioned technical proposal, it is preferred that the depth of the limit hole is 3-6mm.

The beneficial effects of the present invention are: using when a wherein straight-bar for the U-shape lock ring first can be initially inserted into In one lockhole, the U-shape lock ring is then rotated, another straight-bar on the U-shape lock ring, which is resisted against, described can stretch On the limit plate, the limit plate stress is bounced back in the lock body, when this root straight-bar is totally placed in second lockhole When middle, the limit plate is driven stretching until being inserted into the limit hole on the lock body by elastic mechanism, makes the second lock The opening in hole is closed.Above setting keeps the present invention easy to use, not will cause lock ring and the stuck state of lockhole, significantly Improve practicability and convenience.

Specific embodiment

In figs. 1-5, a kind of U-shaped mortise lock convenient for locking, including U-shape lock ring 1, lock body 2 are provided on the lock body 2 Lockhole, the lockhole inside are provided with lock pin 4, and the inside of the 1 lower part straight-bar of U-shape lock ring is evenly distributed with multiple locked grooves 5, the lockhole Including the first lockhole 31 and the second lockhole 32, opening, the lower part straight-bar of the U-shape lock ring 1 are provided on second lockhole 32 It can be placed in second lockhole 32 by the opening, the lock body 2 is provided in the inside of second lockhole 32 The limit plate 7 that can be stretched, 7 end of limit plate are provided with two springs 8, original state, and the spring 8 drives the limit Position plate 7 is inserted in the limit hole 9 on the lock body 2, and the depth of the limit hole 9 is 4mm.When the lower part of the U-shape lock ring 1 When straight-bar is pressed against on the limit plate 7,7 stress of limit plate is bounced back in the lock body 2, and the U-shape lock ring 1 sticks into described When in the second lockhole 32, the limit plate 7 restores to original state.

In use, first a wherein straight-bar for the U-shape lock ring 1 is initially inserted into the first lockhole 31, institute is then rotated U-shape lock ring 1 is stated, another straight-bar on the U-shape lock ring 1 is resisted against on the limit plate 7 that can be stretched, it is described 7 stress of limit plate bounces back in the lock body 2, when this root straight-bar is totally placed in second lockhole 32, the limit Plate 7 is stretched out by the driving of spring 8 up to being inserted into the limit hole 9 on the lock body 2, and the opening of the second lockhole 32 is made It closes.

Wherein, 7 both ends of limit plate have thickness difference, and the thickness close to 2 center of lock body is less than close to 2 outside of lock body Thickness.When locking states, the shortest distance of the limit plate 7 and the lower part straight-bar of the U-shape lock ring 1 is 1mm.In this way, When external force push the limit plate 7 when, the limit plate 7 can be resisted against on the U-shape lock ring 1, prevent the limit plate 7 by Power retraction, guarantees the safety of U-shape lock.
