Description

Lock

Technical field

The utility model relates to a lock. The lock can be applied to various types of package locks, box locks, cabinet locks, door locks, etc., such as handbags, pencil cases and the like, which can realize the opening and locking of the locks.

Background technique

At present, the lock structures commonly used in the market are various and complex, with many parts and high costs.

technical problem

Technical solution

The purpose of the utility model is to provide a lock device which realizes low cost, convenient production and good reliability; the ball and the slider are assembled in the lock body shell with the bolt, and the effective specific space is made. The slider pushes the marble to allow the marble to occupy the space inside the pin hole. The ball's own scrolling characteristics and specific duty cycle characteristics are used to achieve the function of locking and unlocking.

In order to achieve the above object, the technical solution of the present invention is as follows:

A lock body, comprising: a lock body shell 1, a marble 2, a slider 3, a bolt 4, a marble 2, a slider 3 are assembled in the lock body shell 1; a first slot 11 is defined in the lock body shell 1, The second slot 12, the slider 3 can move up and down axially in the first slot 11; the pinball 2 can roll laterally left and right in the second slot 12; the latch 4 can insert and pull out the lock body shell 1, and the latch 4 has a hole 41 with a ball fit; the slider 3 has a first end surface 31, a second end surface 32, and when the slider 3 moves up to the top end of the first groove 11, the second end surface 32 abuts the marble 2; the slider 3 moves downward to the At the bottom end of a slot 11, the first end surface 31 abuts the marble 2; the slider 3 can push the marble 2 to roll rightward in the second slot 12; when the marble 2 rolls to the right, the left half portion remains in the second slot 12 The inner and right half portions are rolled into the hole 41 to form a limit action of the pin 2 on the pin 4, and are locked; when the ball 2 rolls to the left, the space occupied by the hole 41 is released, and the pin 2 is no longer limited to the pin 4. Bit, unlocked.

The second groove 12 on the lock body casing 1 may have an inclined structure to facilitate the rolling of the marble 2 to the left by its own gravity.

The first end surface 31 has an inclined structure or a curved surface structure to facilitate engagement with the marble 2 when the slider 3 moves upward.

Due to the adoption of the above structure, the safety and reliability of the lock are improved, and the structure is simple, exquisite and compact, and is suitable for a wide range of promotion and application.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

a lock body, comprising: a lock body shell 1, a marble 2, a slider 3, a bolt 4; a marble 2, a slider 3 is assembled in the lock body shell 1; a first slot 11 is defined in the lock body shell 1, The second slot 12, the slider 3 can move axially up and down in the first slot 11; the latch 4 can insert and pull out the lock body shell 1, the bolt 4 has a hole 41 matching the marble; the pin 2 can be in the second slot 12 is horizontally scrolled left and right; the slider 3 has a first end surface 31 and a second end surface 32. When the slider 3 moves up to the top end of the first slot 11, the second end surface 32 abuts the marble 2; the slider 3 moves downward to the first At the bottom end of a slot 11, the first end surface 31 abuts the marble 2; the slider 3 can push the marble 2 to roll rightward in the second slot 12; when the marble 2 rolls to the right, the left half portion remains in the second slot 12 The inner and right halves are rolled into the hole 41 to form a limit action of the pin 2 on the pin 4.

As shown in FIG. 1 , the slider 3 is moved upward to the top of the first slot 11 to push the pin 2 to the right to lock the state diagram of the pin 4; when the slider 3 moves upward, the first end face 31 is opposite to the pin 2 And pushing the marble 2 to the right, at this time, the second end surface 32 is opposite to the marble 2, and the limit action of the slider 3 on the marble 2 is realized; the left half of the marble 2 is in the second slot 12 and the right half is deep into the hole 41. The latch 4 inserted into the lock body case 1 is locked, so that the latch 4 cannot be pulled out of the lock body case 1 to form a locked state.

As shown in FIG. 2, the slider 3 is moved downward to the bottom end of the first slot 11, the marble 2 is rolled to the left, and the unlocking state is a schematic sectional view; when the slider 3 is moved downward, the second end surface 32 is no longer with the marble 2 At the same time, the resistance of the slider 3 to the marble 2 disappears. At this time, the external force exerts an upward pulling force on the pin 4, and the pin 4 generates a thrust force when the pin 4 moves upward; meanwhile, since the second slot 12 where the pin 2 is located is a bevel groove And the marble 2 is a ball that can be rolled, so the marble 2 is rolled to the lower left by the self-gravity and the thrust generated when the bolt 4 moves upward, and is opposite to the first end surface 31, and the space occupying the hole 41 is released. The pin 2 is no longer limited to the pin 4, and the pin 4 can smoothly pull out the lock body casing 1 to achieve the purpose of unlocking.

The above-described embodiments are merely illustrative of several embodiments of the present invention, and the description thereof is more specific and detailed, but is not to be construed as limiting the scope of the invention; it should be noted that those skilled in the art It is to be understood that modifications and improvements may be made without departing from the spirit and scope of the invention. Modifications are intended to fall within the scope of the claims of the invention.
