[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figure 1 , Figure 2 As shown, this embodiment provides a push-type lock that can be used in an extremely short wheelbase, which is composed of a lock tongue mechanism ( Figure 3 , Figure 4 ) and lock box mechanism ( Figure 5 , Figure 6 ), the bolt mechanism includes a bolt 11, a ball 2, a small spring 3, a large spring 4, a housing 5, a top cover 6 and a rotating shaft 10; the lock box mechanism includes a lock plate 7, a lock base 8 and a fixing pin 9. The bolt 1 in the bolt mechanism cooperates with the lock box mechanism to realize the opening and locking functions of the lock.

[0030] like Figure 3 , Figure 4 The bolt mechanism shown includes a bolt 1, a ball 2, a small spring 3, a large spring 4, a housing 5 and a top cover 6. The housing 5 is composed of a mounting seat and a protrusion fixed on the mounting seat. The housing 5 serves as the main frame of the bolt mechanism and provides a mounting position for other components. A through hole is provided at the center of the bolt 1, and a connecting hole deviating from the axis of the protrusion is also provided on the protrusion. The rotating shaft 10 passes through the two holes to enable the bolt 1 to be rotatably connected to the protrusion. The sleeve is installed on the rotating shaft 10, which can ensure that the bolt 1 is less worn when rotating and is smoother. The bolt 1 is connected to the housing 5 through the rotating shaft 10, and the locking and separation of the lock plate are achieved by rotating around the rotating shaft 10.

[0031] The protruding part is provided with a receiving groove, and the lock tongue 1, the ball 2 and the small spring 3 are sequentially arranged in the receiving groove. Semi-circular grooves are provided on both sides of the receiving groove to limit the displacement of the ball 2 and the small spring 3. When the push-type lock is closed or opened, the small spring 3 will only reset and compress in the specified groove, thereby driving the rotation of the ball 2, and finally generating an eccentric force on the lock tongue 1. The presence of the ball 2 eliminates the direct contact between the small spring 3 and the lock tongue 1, effectively reducing the jamming generated during the contact between the small spring 3 and the lock tongue 1, and reducing the failure rate of the push-type lock.

[0032] The top cover 6 includes a cover body and a guide portion. The cover body is provided with a through hole that runs through the opposite sides thereof. The through hole matches the shape of the protruding portion, and the top cover 6 is sleeved on the outside of the protruding portion through the through hole. On the side of the cover body close to the mounting seat, a plurality of guide portions are arranged at intervals along the circumference of the through hole. A large spring 4 sleeved on the protruding portion is also provided between the top cover 6 and the mounting seat. The guide portion extends into the large spring 4, so that one end of the large spring 4 is fixedly connected to the top cover 6, and the other end is fixedly connected to the mounting seat, which is used to reduce the displacement of the large spring 4 during the resetting and compression process. The guide portion can be in the form of a sheet, which is used to increase the contact area with the large spring 4, better stabilize the resetting and compression of the large spring 4, and reduce the generation of errors.

[0033] like Figure 5 , Figure 6 The lock box mechanism shown includes a lock plate 7, a lock base 8 and a fixing pin 9. The lock box mechanism and the lock tongue mechanism move in coordination to achieve closing or opening of the lock.

[0034] The lock base 8 is provided with avoidance openings that penetrate through the opposite sides thereof. During the closing or opening process of the push-type lock, the lock base 8 penetrates the protruding portion through the avoidance openings. The locking plate 7 is provided on the opposite sides of the lock base 8 close to the top cover 6, and the locking plate 7 partially overlaps with the avoidance openings. The opposite sides of the lock base 8 where the locking plate 7 is not provided are provided with connecting holes for connecting the lock base 8 to the outside. The lock base 8 is provided with a plurality of L-shaped protrusions, and the two ends of the locking plate 7 extend in the protrusions correspondingly, so that the locking plate 7 is fixedly connected to the lock base 8. The lock base 8 is also provided with a plurality of fixing pins 9, which are located on both sides of the locking plate 7 and are used to limit the locking plate 7.

[0035] The utility model is a push-type lock that can be used in an extremely short wheelbase. The lock tongue 1 is connected to the housing 5 through a rotating shaft 10 to form the main frame of the push-type lock. A shaft sleeve is provided between the rotating shaft 10 and the housing 5, and the lock tongue 1 can rotate around the rotating shaft 10. The cooperation of the small spring 3 and the large spring 4 provides a deflecting thrust for the lock tongue 1.

[0036] The lock tongue 1 is connected to the protruding portion of the housing 5 through the rotating shaft 10. Since the connecting hole on the protruding portion deviates from the axis of the protruding portion, one side of the guide shaft lock tongue 1 is away from the protruding portion (side A), and one side is close to the protruding portion (side B). When the push-type lock is in the open state, the lower corner of the side A contacts the inner wall of the top cover 6, and the upper corner of the side A protrudes above the top cover 6. At this time, the small spring 3 contacts the lower corner of the side A through the ball 2. The small spring 3 is in the reset state and pushes the lower corner of the side A upward. The top cover 6 provides support for the lower corner of the side A. Under the joint action of the two, the lock tongue 1 is in a tilted state and remains stationary.

[0037] When the push-type lock needs to be closed, the lock box mechanism is pressed to move downward, and the locking plate 7 in the lock box mechanism will pass over the upper corner of the A side and contact the top cover 6. When the locking plate 7 contacts the top cover 6, the lock box mechanism is stopped from being pressed, and the large spring 4 is reset to push the top cover 6 and the lock box structure upward. In this process, the A side and the B side of the lock tongue 1 gradually extend the protruding part, and when the lower side corner of the A side of the lock tongue 1 contacts the inner wall of the top cover 6, and the upper side corner of the A side of the lock tongue 1 contacts the locking plate 6 of the lock box mechanism, the push-type lock is closed. In this process, the small spring 3 is always in contact with the right angle surface of the lower side angle of the A side through the ball 2, and provides an upward eccentric force to make the lock tongue 1 rotate counterclockwise.

[0038] When the push-type lock is in the closed state, when it is necessary to open the push-type lock, the lock box mechanism is pressed downward again, and the locking plate 7 presses the top cover 6 downward, causing the locking plate 7 to contact the top cover 6, and move downward together to compress the large spring 4. The lower side angle of the A side is pushed by the locking plate 7 and the top cover 6, causing the lock tongue 1 to rotate clockwise. Due to the clockwise rotation of the lock tongue 1, the small spring 3 will gradually change from contacting the right angle surface of the lower side angle of the A side through the ball 2 to contacting the arc surface of the lower side angle of the A side. When the ball 2 contacts the arc surface of the lower side angle of the A side, the direction of the eccentric force on the lock tongue 1 is changed, which will cause the push on the lock tongue 1 to change from counterclockwise to clockwise. The clockwise rotation of the lock tongue 1 will be further pushed, so that the A side and the B side of the lock tongue are further retracted into the protrusion.

[0039] When the lock box mechanism stops being pressed, the large spring 4 stretches and resets to push the top cover 6 and the lock box structure upward. In this process, since the small spring 3 contacts the arc surface of the lower side angle of the A side through the ball 2, the lock tongue 1 generates an eccentric force to rotate clockwise. When the lock plate 7 and the top cover 6 move upward, the upper side angle of the A side will not prevent the lock plate 7 from moving upward. When the small spring 3 contacts the right angle surface of the lower side angle of the A side through the ball 2, the lock tongue 1 starts to rotate counterclockwise, the top cover 6 is between the lower side angle and the upper side angle of the A side, and the lock plate 7 is located above the upper side angle. At this time, the push-type lock is opened.

[0040] By adopting the above technical solution disclosed in the utility model, the following beneficial effects are obtained:

[0041] The present invention has a simple and reasonable structure and strong stability. In actual use, the lock tongue 1 realizes the movement of the lock tongue 1 through two springs, and the lock tongue 1 is connected to the shaft sleeve through the rotating shaft 10, so that the lock can be opened and closed smoothly. The lock box mechanism optimizes the lock plate structure and adopts two lock plates 7. The structure of the lock plate 7 is movable. During the pressing process, the lock plate 7 will not hinder the movement of the lock tongue mechanism, so that the opening and closing can be achieved at a very small distance from the opening and closing axis to the lock center, which improves the use scenario of the push-type lock.
