Description

Tapered end structure for U-shaped lock

Technical Field

The invention relates to the field of hardware, in particular to a lock head structure for a U-shaped lock.

Background

The lock is an indispensable articles for daily use in people's life, and along with the continuous improvement of living standard, people not only pay close attention to the safety of lock extremely, also pay more and more attention to appearance and the quality of lock shell. U type mortise lock is often used for places such as office, shop and storefront, the tapered end structure of tapered end structure is generally the cuboid form for current U-shaped lock, the structure is less, key slot on it is embedded on one side to be set up in one side of tapered end, people are when locking the door, on the U-shaped locking lever is being fallen with the tapered end easily, and when exerting oneself too big back, extremely easily impel the tapered end to the place that is close to the door, only leave less gap like this, cause the key can't insert in the key slot with normal angle, therefore cause the dilemma that the door can not be opened, only will destroy, just can open.

Therefore, those skilled in the art have been devoted to developing a lock head structure for a U-lock that does not insert the lock head backwards.

Disclosure of Invention

In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a lock head structure for a U-shaped lock, which can solve the problem that the U-shaped locking bar of the existing U-shaped mortise lock is difficult to insert into the lock head.

In order to achieve the purpose, the invention provides a lock head structure for a U-shaped lock, which comprises a body, wherein the body is provided with a lock hole and a key slot, a handle is arranged above the body and comprises two vertical parts and a transverse straight part, two ends of the transverse straight part are respectively connected with one end of the vertical part through a transverse rod, and the transverse straight part and the key slot are arranged on the same side.

Preferably, the upper surface and the lower surface of the body are both provided with positioning holes.

Preferably, the upper surface of the body is provided with five positioning holes, and the lower surface of the body is provided with one positioning hole.

The handle is arranged above the lock body, the direction of the handle is the same as the direction of the key slot, so that people can visually judge the opening direction of the key slot when using the lock head to lock the door, and when using the lock, people can hold the handle after the lock hole is aligned with the U-shaped lock rod, and push the lock head into the U-shaped lock rod according to actual requirements, thereby effectively preventing the embarrassing situation that the key slot faces inwards, and the gap between the lock and the door is very small, so that the lock cannot be unlocked.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, wherein the terms "upper", "lower", "left", "right", "inner", "outer", and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is for convenience and simplicity of description, and does not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular manner, and thus should not be construed as limiting the present invention. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 to 3, a lock head structure for a U-shaped lock comprises a body 1, wherein a lock hole 2 and a key slot 3 are arranged on the body 1, and a handle 4 is arranged above the body 1; the handle 4 comprises two vertical parts 4a and a transverse part 4b, and two ends of the transverse part 4b are respectively connected with one end of the vertical part 4a through a cross rod 4 c; the horizontal straight portion 4b is on the same side as the key slot 3.

According to the invention, the handle is arranged on the lock head, so that people can conveniently identify the direction of the key slot 3, meanwhile, the handle is beneficial to applying force to lock the door, and the door locking efficiency is improved.

The upper surface and the lower surface of the body 1 are both provided with positioning holes 5; compared with the existing lock with a smooth surface, the upper surface of the body 1 is provided with five positioning holes 5; the positioning hole 5 is formed in the lower surface of the body 1, the positioning hole is formed in the lock head, when people hold the lock head, fingers can be embedded into the positioning hole, the lock head can be prevented from sliding off the hands, and the positioning hole can be designed to be in the shape of the fingers in order to improve comfort.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
