Background

The secret room escape, also known as TAKAGISM, is an on-line puzzle solving game, and generally requires a player to find clues in the game and walk out of the secret room step by step.

The escape of the real-person secret room originates from the online secret room escape game, but the limitation and the constraint of the computer game are broken, the essence of the secret room is shown in original juice and original taste, a player can experience a real scene personally, and the game is more entertaining. Meanwhile, the real-person private room escape keeps the characteristics of private room escape exercise reasoning and logical thinking ability, and for a team, the team cooperation ability can be exercised, so that the method is a new and effective group building project.

In the escape game of the secret room, the structure of the lock is an important tool, and a great deal of entertainment property is added to the game process, but in the long-term process, the service life of the lock is always the stability which is difficult to solve by a user, and a stable lock with long service life is of great importance.

Disclosure of Invention

The invention aims to provide a mechanical door lock structure which is simple in structure and long in service life.

In order to solve the technical problems, the invention adopts the technical scheme that:

the utility model provides a machine closes lock structure, includes internal gear, rotation axis, external gear, ratchet structure and slip rack, be provided with the mounting hole on the door body, the rotation axis rotates and installs in the mounting hole, external gear fixed mounting is in the rotation axis outer end, the internal gear rotates and installs in the mounting hole bottom, the rotation axis passes the internal gear, the ratchet includes ratchet, ratchet and spring, the ratchet equidistance rotates and installs the periphery at the rotation axis, the spring mounting is on the rotation axis, stimulates the ratchet return stroke, the ratchet is installed in the internal gear bottom, ratchet and ratchet cooperation, and one-way transmission is connected, slip rack slidable mounting is in the door body, with the internal gear transmission cooperation.

Further, a rolling structure is further arranged, the rolling structure comprises a ball, a sliding groove, an inner side limiting ring and an outer side limiting ring, the sliding groove is respectively located at the bottom of the mounting hole and the outer end face of the inner gear, the ball is fully distributed in the sliding groove, and the inner side limiting ring and the outer side limiting ring limit the ball to move towards the outer side of the sliding groove.

Furthermore, a lock hole is formed in the outer end face of the outer gear.

Further, the external gear is in transmission connection with an external motor.

The invention has the beneficial effects that:

1. mechanical structure has improved the life-span of this lock, and the rolling structure who sets up has increased the stability of internal gear and external gear rotation in-process, has improved the life-span.

2. The ratchet wheel ratchet is used for driving the inner gear to rotate, the structure is simple, and the operation is convenient.

3. The unlocking and locking actions can be completed manually or driven by a motor.

Drawings

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

FIG. 1 is a schematic view of the present invention mounted to one of the door bodies.

Fig. 2 is a cross-sectional view of the present invention.

Fig. 3 is a sectional view of the rolling structure of the present invention.

FIG. 4 is a schematic view of the ratchet structure of the ratchet of the present invention.

Wherein: the device comprises an internal gear-1, a rotating shaft-2, an external gear-3, a ratchet wheel and ratchet structure-4, a sliding rack-5, a mounting hole-6, a ratchet-7, a spring-8, a ratchet wheel-9, an annular sliding groove-11, a ball-12, an inner limiting ring-13 and an outer limiting ring-14.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

The first embodiment is as follows:

referring to fig. 1, 2 and 4, a mechanical door lock structure includes an internal gear 1, a rotating shaft 2, an external gear 3, a ratchet structure 4 and a sliding rack 5, a mounting hole 6 is formed on a movable end door body, the rotating shaft 2 is rotatably mounted in the mounting hole 6, the external gear 3 is fixedly mounted at the outer end of the rotating shaft 2, the outer end surface of the external gear 3 is flush with the outlet of the mounting hole 6, so that the appearance is more attractive, the internal gear 1 is rotatably mounted at the bottom of the mounting hole 6, the rotating shaft 2 penetrates through the internal gear 1, namely, the rotating shaft 2 is not directly in transmission connection with the internal gear 1, a plurality of ratchets 7 are rotatably mounted at the tail end of the rotating shaft 2 at equal intervals, a spring 8 is mounted on the rotating shaft 2, two ends of the spring are respectively connected with the rotating shaft 2 and the ratchet, when the ratchet 7 rotates forwards, the ratchet 7 is matched with the ratchet 9 to drive the internal gear 1 to rotate forwards, the same rotating shaft 2 rotates backwards, the ratchet 9 is not matched with the ratchet 7, the spring 8 can pull the ratchet 7 to return, the sliding rack 5 is movably arranged in the door body, the sliding rack 5 is matched with the internal gear 1, and obviously, the internal gear 1 can drive the sliding rack 5 to move only when the ratchet rotates forwards.

Referring to fig. 3, in order to improve the stability of the internal gear 1 and the external gear 3, annular chutes 11 are respectively disposed at the bottom of the mounting hole 6 and outside the internal gear 1, balls 12 are mounted in the annular chutes 11 in a rolling manner, the balls 12 are distributed over the chutes 11, the balls 12 are positioned by an inner limiting ring 13 and an outer limiting ring 14, and the internal gear 1 and the external gear 3 are respectively in contact with the balls at the bottom of the mounting hole 6 and the balls 12 on the outer end surface of the internal gear 1 for supporting.

The mode of opening this lock has the multiple, and the first is to set up the lockhole at outer terminal surface of outer gear 3, and the manual work uses the lock core wrench movement to drive outer gear 3 and rotate, accomplishes to unblank, and the second is to be provided with outside motor, and this motor has outer gear 3 transmission to connect to the mesh of control switch lock.
