Description

Office lock of furniture

Technical Field

The invention relates to a locking device, in particular to a mechanical lock of furniture.

Background

With the emphasis of the state on the traditional culture, various non-legacy items are actively excavated and protected by governments of various places according to superior instructions, the inventor actively responds to the government call, the excavation and protection are carried out on mortise and tenon skills and organ hidden lattices of traditional furniture, and as the safe box is not available in the times of Ming and Qing and the various locks such as the modern times are few, the craftsman can design some hidden lattices on the furniture for hiding valuable articles, the general design is more hidden and requires skills for opening, but the hidden lattices and the switch devices in a plurality of traditional furniture are lost, so the inventor redesigns various hidden lattices and the switch devices, and provides a mechanical lock of the furniture to fill the defects.

In view of the above-mentioned drawbacks, the inventors of the present invention have finally obtained the present invention through a long period of research and practice.

Disclosure of Invention

The present invention aims to provide a mechanical lock for furniture, which overcomes the technical defects.

In order to achieve the purpose, the invention adopts the technical scheme that the mechanical lock of the furniture comprises a panel, a back plate and a lock tongue, wherein a first handle and a second handle are arranged on the panel, a first shaft is arranged on the first handle, a second shaft is arranged on the second handle, a first shaft sleeve is arranged on the first shaft, a second shaft sleeve is arranged on the second shaft, a groove is formed in the surface of the panel opposite to the back plate, and the first shaft sleeve, the second shaft sleeve and the lock tongue are all arranged in the groove;

the first shaft penetrates through the panel, the first shaft sleeve and the end face of the bolt and is fixed with a screw penetrating through the back plate, and the first shaft sleeve is fixed with the first shaft through a pin;

the second shaft penetrates through the panel and the second shaft sleeve to be coupled with the back plate;

the tail part of the lock tongue is provided with a tenon, and the second shaft sleeve is provided with a mortise matched with the tenon;

the first shaft sleeve is provided with a notch matched with the diameter of the second shaft sleeve;

the panel is provided with a long hole which can enable the first shaft to move up and down at the position where the first shaft penetrates, and the back plate is provided with a long screw hole which can enable the first shaft to move up and down at the position where the screw penetrates;

the diameter of the first shaft sleeve is larger than that of the first handle, and the diameter of the second shaft sleeve is larger than that of the second handle.

Compared with the prior art, the invention has the beneficial effects that: the mechanical lock of the furniture can be opened without a password or a key by a skill method, so that the hidden lattice in the traditional furniture is opened by a more method.

Detailed Description

The technical features and advantages of the present invention are described in more detail with reference to the accompanying drawings.

The embodiment provides a mechanism lock of furniture, including panel 1, backplate 2 and spring bolt 5, be provided with first handle 7 and second handle 8 on the panel 1, be provided with primary shaft 9 on the first handle 7, be provided with secondary shaft 10 on the second handle 8, be provided with first axle sleeve 3 on the primary shaft 9, be provided with secondary shaft sleeve 4 on the

secondary shaft

10, 1 the panel is provided with the recess with the opposite face of backplate 2, primary shaft sleeve 3, secondary shaft sleeve 4 and spring bolt 5 all set up in the recess, primary shaft 9 passes panel 1, primary shaft sleeve 3 and spring bolt 5 terminal surface are fixed with screw 15 that passes backplate 2, primary shaft sleeve 3 passes through the pin and is fixed with primary shaft 9. The second shaft 10 penetrates through the panel 1 and the second shaft sleeve 4 to be coupled with the back plate 2, the tail part of the bolt 5 is provided with a tenon 13, the second shaft sleeve 4 is provided with a mortise 14 matched with the tenon 13, the first shaft sleeve 3 is provided with a notch 6 matched with the diameter of the second shaft sleeve 4, the panel 1 is provided with a long hole 11 capable of enabling the first shaft 9 to move up and down at the penetrating part of the first shaft 9, and the back plate 2 is provided with a long screw hole 12 capable of enabling the first shaft 9 to move up and down at the penetrating part of a screw 15; the diameter of the first shaft sleeve 3 is larger than that of the first handle 7, and the diameter of the second shaft sleeve 4 is larger than that of the second handle 8; when the mechanical lock is to be unlocked, the notch of the first shaft sleeve 3 needs to be downward, the mortise 14 of the second shaft sleeve 4 needs to be upward aligned with the tenon 13, the first handle 7 is moved downward, the bolt 5 is also moved downward at the same time, the mechanical lock is unlocked, when the mechanical lock is to be locked, the first handle 7 is moved upward, the bolt 5 is also moved upward at the same time, and the mechanical lock cannot be unlocked as long as the first handle 7 or the second handle 8 or both the first handle 7 and the second handle 8 are rotated after the mechanical lock is moved upward.
