Description

A mechanical lock

technical field

The present invention relates to an operating tool under the sharing economy mode, in particular to a mechanical lock, which is suitable for fixed-point borrowing and returning of small-sized shared products such as umbrellas.

Background technique

With the in-depth development of the Internet and the interactive evolution of the new generation of information technology and innovation, the development of the sharing economy has been promoted. Sharing economy, also known as sharing economy, refers to a social system that allows goods, services, data resources, etc. to have shared channels. In recent years, the sharing economy has developed rapidly, and the vigorous development of the sharing economy represented by shared bicycles has led to the widespread launch of sharing economies in other industries and fields. For example, smaller products, such as umbrellas, horses, charging treasures, etc., can all be operated under the operation mode of shared bicycles, but the attributes of these small-sized products determine their borrowing and returning methods and the pile-free borrowing and returning of shared bicycles. The models are different, and these products are more suitable for situations with fixed storage points. At fixed storage points, set up special locks to realize self-service borrowing and returning under unattended conditions.

detailed description

Embodiment: see Fig. 1-4.

The invention discloses a mechanical lock, comprising a housing 1 and two holding arms 2, one end of the holding arms 2 is located inside the housing 1 and connected to the housing 1 by a rotating hinge, and the other end It is in the shape of a hook and protrudes from the outside of the housing 1. The hook ends of the two holding arms 2 are relatively bent to form a holding ring. There is also a linkage rod 3 inside the housing 1. The linkage One end of the rod 3 is located inside the housing 1, and the other end protrudes from the opening of the side wall of the housing 1. A sliding block 5 is set on the outside of the linkage rod 3, and a sliding block 5 is provided between the sliding block 5 and the holding arm 2. Diagonal stay rod 6, the two ends of said diagrid stay rod 6 are respectively connected with slide block 5 and holding arm 2 through rotating pin; There is also a sliding pin 11 that penetrates its surface, and the sliding pin 11 slides in the slideway 12. When the two holding arms are closed to form a holding circle, the free end of the linkage rod 3 is located inside the opening of the side wall Or flush with the opening of the side wall, when the two holding arms 2 are opened, the linkage rod 3 protrudes from the opening of the side wall.

The mechanical lock of the present invention can be applied in many fields. Under the premise of vigorous promotion of the sharing economy, the lock can be used as a lock of various shared products, such as shared umbrellas, shared gadgets and so on. Taking a shared umbrella as an example, when the holding arm 2 is opened as shown in Figure 2, put the umbrella handle of the umbrella between the two holding arms, press the linkage lever 3 by the umbrella handle, and the linkage lever 3 is pressed back into the housing, holding The holding arm 2 is in the state shown in Figure 1. When the umbrella needs to be taken out, by pressing the button outside the casing, the corresponding circuit structure inside the casing will drive the linkage lever 3 with an external force, and the holding arm can be opened to take it out. .

One end of the linkage rod 3 located inside the housing 1 is provided with a locking block 7, and both sides of the bottom of the housing 1 are respectively provided with a limiting block 8 and a locking position 9, and the limiting block 8 is provided with There is an electronic lock, the locking position 9 is provided with a sensor linked with the electronic lock, the lower end of the dead bolt 15 of the electronic lock is an inclined plane, and the electronic lock can be a common product on the market, limited in Fig. 1 and Fig. 2 The inside of the bit block is provided with a compression spring for ejecting the dead bolt, which is not shown in the figure, and the upper end of the contact surface adjacent to the locking tongue of the linkage rod 3 is provided with an inclined surface matching the inclined surface of the dead bolt. 3 is pressed back into the housing 1, and the inclined surface at the end of the lock tongue 15 is pressed through the inclined surface above the linkage rod 3, the linkage rod passes through the lock tongue smoothly, and the linkage lever 3 presses the lock tongue 15 back, and on the right side of the linkage lever 3 A bayonet 16 is provided on the side wall, and then the lock tongue pops out repeatedly to engage and lock with the bayonet 16 on the side of the linkage rod 3; The open state of 2 changes to when the sensor sends an unlock command to the electronic lock, the dead bolt retracts, and the linkage rod 3 protrudes out of the housing under the action of external force.

When it is necessary to take out the locked object, that is, to change the lock from the locked state in Figure 1 to the open state in Figure 2, it is only necessary to send an unlock command to the electronic lock through the sensor, and the linkage of the sensor can be achieved through the Set the unlock button on the body 1, or click the unlock command on the mobile phone APP, the communication module of the mobile phone and the sensor realize intercommunication, the unlock button triggers the sensor circuit, and then the sensor circuit triggers the unlock command of the electronic lock. This is a conventional technology in the field of electronic locks, and will not be described in detail here. After the dead bolt is retracted, the holding arm can be opened by exerting a slight external force on the linkage rod.

A guide groove 4 is provided in the housing, and the linkage rod 3 slides in the guide groove 4 .

Both sides of the linkage rod 3 are respectively provided with guide sub-rods 10, wherein the position of the end of one guide sub-rod 10 matches the position of the limit block 8, and the end of the other guide sub-rod 10 matches the position of the locking block 7. connect.

A secondary guide groove 13 is provided on the outside of the secondary guide rod 10 , and the secondary guide rod 10 and the secondary guide groove 13 are symmetrically arranged on both sides of the linkage rod 3 .

A compression spring 14 is sheathed on the outside of the guide sub-rod 10 .

The mechanical lock in this case uses mechanical driving force to push back the linkage lever 3 when the object enters, and needs to use the external force in the housing to drive the linkage lever 3 when the object is taken out, so as to open the two holding arms, which can be applied to the sharing economy Storage and removal of various objects.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent transformations made by using the description of the present invention and the contents of the accompanying drawings or directly or indirectly used in the relevant technical fields are all included in this patent. inventions within the scope of patent protection.
