Description

Device for preventing U-shaped lock rod from being cut off and preventing two ends of lock body from being smashed and protecting lock hole

Technical Field

The technical field that this patent scheme involved is the safety protection technical field of U type tool to lock. In particular to a protection device which is specially used for preventing a lock rod of a U-shaped lock from being sheared by hydraulic scissors.

Background

U-lock is a very widely used anti-theft product, but there are many methods and tools that can be opened without a key, and there are mainly technical unlocking and destructive unlocking. The lock is mainly used for locking bicycles, two-wheeled or three-wheeled electric vehicles and motorcycles, and a plurality of U-shaped locks for locking glass doors.

Problems and disadvantages with U-locks, and the reasons for them, and problems that have been encountered when solving these problems:

as various unlocking techniques and methods are widely spread in modern society, the number of unlocking tools sold on the network is increasing, and the number of theft cases of bicycles, two-wheel or three-wheel electric vehicles and motorcycles is also endlessly, the safety protection performance of the U-shaped lock needs to be improved urgently to prevent or reduce the loss caused by theft.

However, since the lock rod of the U-lock is thin and thick but difficult to machine, the lock rod of the U-lock is easily sheared by a large force or a hydraulic shear, and it is difficult to prevent such a destructive unlocking means.

From the issued patents under the category of the patent office E05b, of the hundreds, the ones that individually relate to the resistance to shearing are also said to be more resistant to shearing with the use of a stiff material; mention is made of little protection against pounding; the protection lockhole is protected by a plurality of examples, but most of the protection lockholes are waterproof and dustproof, and the like, and also have individual tools, generally speaking, the A-grade lock cylinder is difficult to be opened technically, the side column lock, the blade lock and the lock cylinders with special lockholes are difficult to be opened technically, but the protection lockholes with the comprehensive protection performance are not seen.

In order to prevent the U-shaped lock from being illegally opened, the protection device which can be effectively combined with the lock rod of the U-shaped lock and can be applied in a matched mode is designed, and the purpose of preventing the U-shaped lock from being stolen is achieved better.

Disclosure of Invention

The technical problem that this patent will solve:

how is the U-shaped locking bar prevented from being sheared?

The technical scheme who this patent adopted:

in order to solve the problems, the technical scheme of the protection of the lock rod of the U-shaped lock in the aspect of shearing is conceived.

Problem with the anti-shear of the locking bar of a U-lock?

The most commonly used tool for shearing the U-shaped locking rod is a hydraulic shear, and is characterized by being high in speed and labor-saving, but the force of the commonly used hydraulic shear is always limited, the shearing opening is also limited in width, the shearing opening of the hydraulic shear on a platform of a certain treasure sales website is 28MM, if the width and the thickness of an object to be sheared are large enough, the object cannot be easily sheared or cannot be sheared at all.

The technical scheme is as follows:

this technical scheme need not process thick locking lever, but installed comparatively thick circular steel pipe as the protective sheath on the locking lever additional, both made ordinary hydraulic pressure cut the mouth difficult or can not put into the U-shaped locking lever, make again even the locking lever and the circular steel pipe cover on it can be put into the mouth of a cut, also because need powerful strength to cut, for example, want to cut the steel pipe of three centimeters or more diameter, be difficult to accomplish, because want to cut the locking stalk, the circular steel pipe of the cover outside the locking lever of cutting earlier, so be difficult for cutting or can't cut. In addition, when the hydraulic shear is difficult to shear, other manual shearing modes are less likely to shear, and the sample in the scheme is a steel pipe with the outer diameter of 32MM and is much larger than the lock rod.

Therefore, the applicant considers that the aim of preventing the lock rod from being cut off, which is to be solved by the technical scheme, is obviously achieved and is established, and the solution of the problem is clear and easy to understand.

The U-shaped lock rod adopting the protection device is not easy to cut off, the sound is very loud when a cutting machine is used, and the U-shaped lock rod cannot be cut at all times when a saw is used.

That is to say that the device of this scheme design can make good better, not so good, also can increase substantially the theftproof performance.

The device of this design mainly includes following four parts:

a first component: "one section both ends are all punched and are had a little U-shaped breach and whole thick steel pipe of the circle of being rolled over into the U-shaped", its characteristics:

(1) the total length of the lock rod is shorter than that of the lock rod of the U-shaped lock, the same pipe bender is also folded into a U shape which is the same as the lock rod, is simultaneously folded with the lock rod and is sleeved outside the lock rod, and if the part is the same as that of a protective clothing which is worn on the periphery of the lock rod;

(2) the diameter of the lock rod is 32MM, which is far larger than the diameter of the lock rod of 16MM, is twice of the diameter of the lock rod, and is obviously larger than the shearing mouth (28MM) of the common hydraulic shear;

(3) the concrete form is as follows: on the surface of the U-shaped steel pipe close to the end parts 10MM of the two lock rods, each U-shaped notch is cut, the notch is slightly wider than the lock body, for example, a lock body with the width of 22MM, the width of the notch is 24MM, each side is 1MM larger, only two ends of the lock body are inserted into parts, and therefore if external force is required to strike two ends of the lock body, the lock tongue is wrapped by the end part of the first part and cannot strike the end part of the lock body, force in two directions for separating the lock tongue and the lock rod of the lock body cannot be generated, and the effects of shearing prevention and partial smashing prevention are achieved at the same time.

A second component: a section of rectangular steel pipe, its characteristic lies in:

(1) the length and the width of the lock body are both larger than those of the lock body, the lock body can be sleeved with the lock body, the length of the lock body is more than half of that of the lock body, but the lock body is shorter than two lock rods or the empty space between the two lock holes, otherwise at least one lock hole is blocked, the two U-shaped lock rods can be influenced, the lock cannot be locked, and therefore, the lock body is slightly away from the lock holes at the two ends;

(2) as shown in fig. 1: the center point position of the surface of one side of the second part is provided with a round hole m2 which is as large as the lock hole, two sides of the round hole are also provided with two rivet holes H1 and H2 on the center line, rivets are arranged, after the lock body is sleeved with 2, when a key is used for unlocking, the lock can be unlocked only by penetrating into the lock cylinder hole m2 through the small hole m1 on the 2, so that the position of the small hole is required in each time of unlocking, after the lock body is sleeved with 2, the shape of the lock cylinder in the lock hole on the lock body cannot be directly observed, after the rivets are arranged with 3 and 4, the lock hole on the 1 and the lock hole on the lock body are separated by a small distance, so that the requirement that others can be better when other technically unlocking needs to still lean against the lock cylinder edge is improved, the pushing force of a hanging arm is changed, and the height from the ground is increased after the lock is locked on a tire, the turning angles of hands and arms and the like, the height and position of the upper body, the head and the eyes of a person are limited and the like, after the second part is reinforced and protected, the shape of the lock cylinder is detected or the structure of the lock cylinder is further speculated and judged, if the lock hole is touched by fingers, the lock cylinder cannot be touched, so that the conditions and requirements are higher if the shape of the lock hole and the shape of the lock cylinder are directly detected, the height of the lock cylinder does not exceed the knee of the person after the lock is locked on the wheel, namely the height of the lock cylinder is usually not higher than 50 cm from the ground, the eyes of the person cannot turn, even if the person squats and uses light to detect the shape, the steps and the time for detecting the shape of the lock cylinder are longer, if the shape of the lock cylinder is not known, technical unlocking cannot be mentioned, the owner of the lock has a key, the lock and the lock cylinder are known and the shape of the lock cylinder is riveted, labor is not required The angle iron is shaped to further block the view of the keyhole structure from both ends. In short, it increases the difficulty and time consumption of technical unlocking.

Parts three and four: is the same 'two small pieces of L-shaped angle iron', and is characterized in that:

the L-shaped angle iron is formed by subtracting the height of the lock body from the inner height of the second part, the width of the L-shaped angle iron is slightly smaller than the inner width of the second part, and a rivet hole H3 is formed in the narrow edge of the third part; a hole H4 is formed in the fourth component so as to be connected with rivet holes H1 and H2 in the second component through rivets;

the function has two points: 1) the lock body is used for sealing two ends of 2 'a section of rectangular steel pipe' after being arranged in the lock body, so that an illegal technician cannot see the shape and the structure of the lock hole from any end;

2) the distance between the edge with the hole of the second distraction part and the edge with the lock hole on the lock body is used for enabling the second distraction part not to directly lean against the lock hole when the second distraction part is prevented, and the second distraction part can only be hung in the air to push away the second distraction part, so that the difficulty of controlling the tool by a hand when the second distraction part is distracted is improved, and the possibility of being distracted is reduced.

Description of the drawings:

fig. 1 is a general schematic diagram.

As shown in the figure: in the figures, 1, 2, 3 and 4 correspond to four components (one, two, three and four) of the device. The middle 1 is a circular steel pipe with the diameter of 32mm, namely a component I; 2, a small rectangular steel pipe for protecting the lock hole, namely a second component; 3. and 4, two small L-shaped angle irons for expanding the distance between the second component and the lock body, namely a third component and a fourth component.

In fig. 1, X is a lock body, Y1 and Y2 are two lock rods, P, Q are two small U-shaped notches at the top end of a U-folded round steel tube, the ends of the lock body are respectively placed into the round steel tube and locked on the lock rods, E, F are two lock rod holes on the lock body, M1 is a key hole on a small rectangular steel tube, M2 is a key hole on the lock body, H1 and H2 are rivet holes on a small rectangular steel tube (part two), and H3 and H4 are rivet holes on L-shaped small angle irons of part three and part four.

The beneficial effect of this patent lies in:

the U-shaped lock rod has the advantages of obviously preventing the U-shaped lock rod from being cut off, has a good protection effect on the prevention in the bud, makes directional expansion on theoretical knowledge and physical devices in a relevant range or research and development of applied products, and defines a new research and development field and range for the U-shaped lock safety protection device in the future. And a certain foundation is laid for developing the U-shaped lockset which can not be stolen in the future.

In particular, with a U-lock with this reinforced protection, manual shearing would not be possible.

And because the two ends of the U-shaped steel pipe are provided with the small U-shaped notches, the end part of the lock body can enter, and the method for effectively preventing the lock body from being effectively struck from the lock hole part to damage the function of the lock is effectively realized.

Moreover, if the lock core is used with an idle lock core, the key can be prevented from being forcibly opened to a certain extent, and if the lock core is used with a so-called ' super B-level ' lock core or a ' C-level lock core such as a blade lock core, the illegal opening prevention performance can be obviously improved.

The specific implementation mode is as follows:

the specific implementation process comprises the following steps:

as shown in the upper part of fig. 1, when locking:

1) the rectangular short steel tube (part two) with the part three and the part four riveted is firstly threaded on the lock body X, as shown in the lower half of figure 1.

2) Then the lock rods Y1 and Y2 sleeved with the first part are inserted into E, F holes on the lock body X and locked, and at the moment, two ends of the lock body are immersed into the round steel tube; and the L-shaped small angle iron of the third component and the fourth component are riveted on the H1 and the H2 of the second component by the holes H3 and H4 respectively and used for expanding a small distance between the lock body X and the second component.

As mentioned above, the device designed and conceived by the scheme has simple and practical structure and simple principle, and is suitable for popularization.

Specifically, the lock rod of the U-shaped lock can have the functions of shearing prevention and partial smashing prevention after only using the U-shaped steel pipe sleeve with the first component; the two, three and four parts can simultaneously have the function of protecting partial lock holes from being illegally opened technically, and the principle and the method are very simple after being understood.

The substantive content is as follows:

the applicant believes that the solution proposed in this patent application is practical and on the basis of this concept has produced samples which, in terms of hydraulic shear resistance, have a clear comparative advantage over the anti-theft performance of the existing U-locks of the conventional type, can improve to a greater extent the anti-theft performance of all existing U-locks of the double-sided opening type, and enable better performance, and are also suitable for single-opening U-locks, with a further improvement in the anti-tamper performance if the width of the lock is matched to the width of the tyre. This can be regarded as a technical solution of the progressive type, and the production, manufacturing and sale at the later stage are also key products.

In summary, it enables a better anti-theft performance of a good lock, the only disadvantage being that the carrying weight sensitivity may be less of a choice, although for powered vehicles this arrangement is clearly considered to be the preferred choice.

For the popular product of the U-shaped lock, the performance of the U-shaped lock is improved only a little, and the U-shaped lock has wide social benefits and is beneficial to users.
