Description

Folding lock folding plate hinge structure

The present invention relates to a folding plate hinge structure of a folding lock, and more particularly to a structure that can increase the strength of the folding plate hinge portion to prevent the folding plate from being damaged by force at the hinge portion.

Generally, the folding lock 1, as shown in the first figure, is mainly composed of a lock head 11 and a plurality of folding plates 12, wherein the folding plate 12 is configured as a long plate, and the folding plate 12 and the hinges 120 at both ends of the folding plate 12 are hinged by rivets 13. However, it is known that the hinges 120 at both ends of the folding lock 1 are relatively weak in strength, and thieves can easily destroy the folding plate 12 by force therefrom. The hinge 120 or rivet 13 of the folding plate 12 of the folding lock 1 may be broken and the anti-theft effect may not be achieved. Therefore, in order to increase the strength of the hinge 120 of the folding plate 12, the hinge 120 at both ends of the folding plate 12 is usually increased in area or thickness for reinforcement. This will increase the trouble in manufacturing, and its strength may not necessarily meet the requirement of preventing damage.

The main purpose of the present invention is to provide a folding plate hinge structure of a folding lock, which can effectively solve the shortcomings of the conventional folding lock when in use.

The folding plate hinge structure of the folding lock of the present invention is mainly composed of a lock head and a folding plate assembly. The folding plate assembly is composed of a plurality of folding plates, a plurality of first sets, a plurality of second sets and a plurality of rivets. The two ends of the plurality of folding plates are respectively provided with a through hole. The two ends of the folding plates are respectively provided with a first set and a second set. A protrusion is provided on a side wall surface of the first set. A through hole is provided on the other side of the first set and passes through the protrusion, a through hole is provided on one side of the second set, and a through hole is provided on the other side of the second set for the protrusion of the first set to be installed. The rivet is inserted through the through hole of the first set, the through hole of the folding plate and the through hole of the second set, and the rivet is riveted to make the two folding plates connected to each other hinged as a whole.

The folding plate hinge structure of the folding lock of the present invention has a tapered hole with a larger diameter on one side opposite to the through holes provided at the two ends of the folding plate.

The folding plate hinge structure of the folding lock of the present invention, wherein the first set and the second set are made of metal material.

The folding plate hinge structure of the folding lock of the present invention has the advantages of increasing the strength of the folding plate and preventing thieves from forcefully destroying the hinged portion of the folding plate, thereby effectively achieving the anti-theft effect.

In order to achieve the above-mentioned purpose and effect, the technical means adopted by the present invention are described in detail as follows with reference to the preferred embodiments and the accompanying drawings:

The embodiment of the present invention, as shown in the second figure, is mainly composed of a lock head 2 and a folding plate set 3. The folding plate set 3 is composed of a plurality of folding plates 30, a plurality of first sets 31, a plurality of second sets 32 and a plurality of rivets 33. The two ends of the plurality of folding plates 30 are each provided with a through hole 300. The through holes 300 provided at the two ends of the folding plates 30 are each provided with a tapered hole 301 with a larger diameter on one of the opposite sides. The two ends of the folding plates 30 are respectively provided with a first set 31 and a second set 32. The first set 31 and the second set 32 are made of metal material. A protrusion 310 is provided on one side wall surface, a through hole 311 is provided on the other side surface of the first set 31 and penetrates the protrusion 310, a through hole 320 is provided on one side surface of the second set 32, and a through hole 321 is provided on the other side surface of the second set 32 for the protrusion 310 of the first set 31 to be set, and the rivet 33 is penetrated through the through hole 311 of the first set 31, the through hole 300 of the folding plate 30 and the through hole 320 of the second set 32, and the rivet 33 is riveted to make the two folding plates 30 connected to each other hinged as a whole, so that a folding plate hinge structure of a folding lock is formed.

When assembling the present invention, please refer to the second to fifth figures. First, a first set 31 and a second set 32 are respectively mounted on the two ends of each folding plate 30, so that the through holes 311 and 320 of the first set 31 and the second set 32 are respectively aligned with the through holes 300 at the two ends of the folding plate 30, and then one end of the two folding plates 30 is placed against each other so that the protrusion 311 of the first set 31 on one folding plate 30 is aligned with the protrusion 311 of the first set 31 on one folding plate 30. 10 is inserted into the through hole 321 of the second set 32 on the other folding plate 30, and then a rivet 33 is penetrated through the through holes 311, 300, 320 of the first set 31, the folding plate 30 and the second set 32, and then the rivet 33 is riveted to hinge the two folding plates 30 together. In this way, the folding plates 30 are hinged and connected to each other, so that the overall assembly can be completed.

When the present invention is used, it is only necessary to unfasten the lock head 2 and then unfold each folding plate 30, as shown in the fourth figure, and wrap the folding plate 30 around the object to be fixed, and then lock the lock head 2 to complete the locking. The present invention is provided with a first set 31 and a second set 32 at the two ends of each folding plate 30, and the protrusion 310 provided in the first set 31 is provided in the through hole 321 of the second set 32, and then riveted by the rivet 33, which can greatly increase the strength of the hinge parts of each folding plate 30, and can prevent thieves from forcefully destroying the hinge parts of the folding plates 30, so as to achieve the best anti-theft effect.

In summary, the present invention has indeed achieved the expected purpose and effect, and is more ideal and practical for those who are familiar with it. However, the above embodiments are only specific descriptions of the preferred embodiments of the present invention, and the embodiments are not used to limit the scope of the patent application of the present invention.
