However, the present box body and the lid are only locked and fixed by a lock tongue, so that the storage box lock mechanism locking is not firm, and the fixing stability between the lid and the box body is not high, which is difficult to meet the requirements that the storage box lock mechanism does not fail under the condition of 4G acceleration, so that the lid is not opened. SUMMARY

[0004] The utility model intends to provide a storage box lock mechanism and storage box, to improve the stability of the storage box lock mechanism locking, improve the firmness and stability of the lid locking on the box body.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme: a storage box lock mechanism, including first lock bar, second lock bar, gear and handle;

[0006] The first lock bar and the second lock bar are both provided with a rack portion, the rack portion of the first lock bar and the rack portion of the second lock bar are located at both sides of the gear respectively, and the rack portion of the first lock bar and the rack portion of the second lock bar are both engaged with the gear;

[0007] One end of the first lock bar and one end of the second lock bar are both fixedly provided with a lock tongue, and the first lock bar and the second lock bar are connected with an elastic member for making the lock tongue extend;

[0008] The first lock bar is provided with a bevel portion, the handle is provided with a sliding portion, and the sliding portion and the bevel portion are slidingly matched;The lock tongue is retracted by controlling the handle to drive the sliding portion to slide on the bevel portion and push the first lock bar to move.

[0009] To achieve the above object, the utility model discloses the following technical scheme: the storage box, including the box and the lid, be equipped with a kind of storage box lock mechanism in the application on the lid, the inner wall of the box is equipped with the lock hole for making lock tongue insertion.

[0010] The principle and advantages of the present application are as follows: the storage box lock mechanism is applied to the storage box, the lid is closed on the box, the first lock rod and the second lock rod are moved by the elastic member, the lock tongue on the first lock rod and the lock tongue on the second lock rod are extended, and the lock tongue is inserted into the lock hole, thereby achieving the locking of the lid and the box.

[0011] When unlocking is needed, the handle is controlled, the handle moves, and the sliding part is driven by the handle to slide on the inclined surface part. The sliding part has a pushing effect on the inclined surface part, thereby moving the first lock rod, retracting the lock tongue on the first lock rod, and making the lock tongue of the first lock rod come out of the lock hole. At the same time, when the first lock rod moves, the first lock rod gear part drives the gear to rotate, the gear drives the gear part of the second lock rod to move, the second lock rod drives the lock tongue to retract from the lock hole, and the lock tongue of the second lock rod comes out of the lock hole, thereby achieving the unlocking of the storage box lock mechanism.

[0012] The storage box lock mechanism in the application achieves the locking of the lid and the box by the two lock tongues on the first lock rod and the second lock rod. Compared with using one lock tongue to lock the lid and the box, the stability of the storage box lock mechanism is improved, the firmness and stability of the lid locked on the box are improved, and the lid is not easy to open in the case of sudden acceleration or sudden braking of the car.

[0013] At the same time, only one handle needs to be controlled in the application, the first lock rod and the second lock rod are linked by the gear, the simultaneous control of the first lock rod and the second lock rod is realized, the simultaneous control of the two lock tongues is realized, the structure design is simple and ingenious. The elastic member has a pulling force on the first lock rod and the second lock rod at the same time, so that the lock tongue can be in the extended state without the help of multiple elastic members, that is, one elastic member can pull the first lock rod and the second lock rod at the same time, so that the lock tongue of the first lock rod and the lock tongue of the second lock rod are in the extended state, and the structure is simpler.

[0014] Preferably, as an improvement, a wedge-shaped part is fixedly arranged on the first lock rod, the inclined surface part is located on the wedge-shaped part, one end of the wedge-shaped part close to the first lock rod is a large end, and the other end of the wedge-shaped part away from the first lock rod is a small end. The inclined surface part is directed to the direction of the lock tongue on the first lock rod. Thus, the sliding part slides on the inclined surface part, the sliding part pushes the wedge-shaped part, the wedge-shaped part drives the first lock rod to move away from the direction of the lock tongue, thereby achieving the retraction of the lock tongue.

[0015] Preferably, as an improvement, a plurality of reinforcing ribs are fixedly arranged on the back of the inclined surface part. Since the inclined surface part continuously bears the pushing force of the sliding part, the structural strength of the inclined surface part is improved by arranging the reinforcing ribs, and the inclined surface part is not easily damaged after the sliding part slides on the inclined surface part for many times, thereby prolonging the service life of the inclined surface part.

[0016] Preferably, as an improvement, a guide part is further arranged, and the first locking rod and the second locking rod are slidingly arranged in the guide part. The guide part guides the sliding of the first locking rod and the second locking rod, thereby making the sliding of the first locking rod and the second locking rod more stable.

[0017] Preferably, as an improvement, the elastic member is a tension spring.

[0018] Preferably, as an improvement, a rotating shaft is arranged on the handle, and the handle can rotate around the rotating shaft; the handle drives the sliding part to slide on the inclined surface part to push the first locking rod to move and realize the retraction of the locking tongue by controlling the rotation of the handle.

[0019] Therefore, the arrangement of the rotating shaft makes the handle rotatable on the box cover, so that when unlocking, the handle is pulled to rotate around the rotating shaft, the handle drives the sliding part to slide on the inclined surface part to push the first locking rod to move and realize the retraction of the locking tongue, thereby realizing the unlocking; after unlocking, the handle is continuously pulled to open the box cover and pull out the inner pot from the box body, and the operations of unlocking, opening the box cover and pulling out the inner pot from the box body can be realized in one step, thereby making the operation simple and convenient.

[0020] Preferably, as an improvement, an elastic part for resetting the handle is further arranged. When the handle is released, the elastic part resets the handle.

[0021] Preferably, as an improvement, the elastic part is a torsion spring, and the torsion spring is sleeved on the rotating shaft.

[0022] Preferably, as an improvement, a metal insert is arranged in the locking tongue. Compared with the locking tongue made of only plastic material, the arrangement of the metal insert greatly improves the structural strength of the locking tongue, the locking tongue is not easily broken or damaged, and the service life of the locking tongue is prolonged, especially in the case of sudden acceleration or sudden braking, the locking tongue is not easily damaged.

[0032] Combination Figures 4-6 As shown, this embodiment discloses a locker mechanism, including a first locking rod 8, a second locking rod 7, a gear 10, and a handle 3.

[0033] In this embodiment, the first locking rod 8 is located above the second locking rod 7 and is arranged horizontally. The first locking rod 8 has a first rack portion 11 integrally formed on it, and the second locking rod 7 has a second rack portion 9 integrally formed on it. The teeth of the first rack portion 11 and the teeth of the second rack portion 9 are arranged opposite to each other. The gear 10 is rotatably mounted on the cover 2 via a shaft. The first rack portion 11 and the second rack portion 9 are located on both sides of the gear 10, and both the first rack portion 11 and the second rack portion 9 mesh with the gear 10.

[0034] Combination Figure 5 As shown in the figure, the left end of the first locking rod 8 and the right end of the second locking rod 7 are both fixed (e.g., by screws) and equipped with a locking tongue 6, which, in conjunction with... Figure 4As shown, the bottom of the first locking rod 8 and the top of the second locking rod 7 are both integrally formed with spring connecting parts. An elastic element 16 for extending the latch 6 is connected between the two spring connecting parts. In this embodiment, the elastic element 16 is a tension spring, with both ends hooked onto the spring connecting parts. Thus, under the pulling action of the elastic element 16, the latch 6 extends from the side of the inner compartment 5 (e.g., ...). Figure 3 (As shown).

[0035] Combination Figure 5 As shown, the top of the first locking bar 8 is integrally provided with a wedge-shaped portion 12, the bottom end of the wedge-shaped portion 12 is the large end, and the top end of the wedge-shaped portion 12 is the small end. The left side of the wedge-shaped portion 12 in the figure has an inclined bevel, facing the direction of the locking tongue 6 of the first locking bar 8. The side of the wedge-shaped portion 12 has a groove, in which a reinforcing rib is integrally formed, located on the back side of the bevel. Combined with... Figure 6 As shown, a protrusion 19 is integrally formed on the top of the back of the handle 3, and a sliding part 13 is integrally provided on the protrusion 19, which slides in conjunction with the inclined part.

[0036] Combination Figure 6 As shown, in this embodiment, the handle 3 and the lid 2 are rotatably connected. Specifically, the rotation is achieved by a pivot 18 between the handle 3 and the lid 2. The pivot 18 provides a rotatable connection between the handle 3 and the lid 2. The pivot 18 is equipped with an elastic component, specifically a torsion spring 17. The torsion spring 17 is fitted onto the pivot 18, with one end of the torsion spring 17 engaged in the lid 2 and the other end engaged in the bottom of the protrusion 19.

[0037] Combination Figure 4 and Figure 5 As shown, the lock mechanism of the storage box in this embodiment also includes a guide portion, which consists of a first guide portion 14 near the latch and a second guide portion 15 near the tail end of the first locking rod 8 (or the tail end of the second locking rod 7). Both the first guide portion 14 and the second guide portion 15 are fixed blocks. The fixed blocks are fixed to the box cover 2 by screws. The fixed blocks are provided with transverse rod holes. The first locking rod 8 and the second locking rod 7 both pass through the corresponding fixed blocks and slide on the fixed blocks.

[0038] To improve the strength of the latch 6, in some embodiments, a metal insert is provided inside the latch 6. By setting the metal insert, the hardness of the latch 6 is increased, and the latch 6 is not easily broken or damaged. Alternatively, the latch 6 can be made of metal directly.

[0039] The bevel at the end of the latch 6 is an arc-shaped spherical surface. As the latch 6 is inserted into the lock hole 4, the contact area between the bevel of the arc-shaped spherical latch 6 and the side wall of the box 1 is small, which helps to reduce the friction between the bevel of the latch 6 and the side wall of the box 1 before the latch 6 enters the lock hole 4.

[0040] The implementation process is as follows: the inner pot 5 is loaded into the box body 1, and the box cover 2 is closed, during the closing of the box cover 2, the inclined surface of the lock tongue 6 slides on the side wall of the box body 1, the first lock rod 8 and the second lock rod 7 slide on the box cover 2, the lock tongue 6 retreats, and after the lock tongue 6 is opposite to the lock hole 4, the lock tongue 6 is inserted into the lock hole 4 again under the action of the elastic element 16, at this time, the box cover 2 cannot be opened. Since two lock tongues 6 are arranged, the two lock tongues 6 are fixed on the left and right sides of the box cover 2 respectively, compared with only one lock tongue 6, the stability of the box cover 2 locked on the box body 1 is higher.

[0041] When it is needed to open the box cover 2, the fingers are put into the finger groove on the box cover 2, and the handle 3 is pulled (pried), the handle 3 rotates around the rotating shaft 18, the handle 3 makes the torsional spring 17 store energy, the handle 3 drives the sliding part 13 to slide downward on the inclined surface part, the sliding part 13 drives the wedge-shaped part 12 to move, the wedge-shaped part 12 drives the first lock rod 8 to move away from the lock tongue 6 thereof, the lock tongue 6 on the first lock rod 8 retreats, and the lock tongue 6 of the first lock rod 8 comes out of the lock hole 4; at the same time, when the first lock rod 8 moves, the first rack part 11 drives the gear 10 to rotate, the gear 10 drives the second rack part 9 to move, the second lock rod 7 moves away from the lock tongue 6 thereof (at this time, the elastic element 16 between the first lock rod 8 and the second lock rod 7 is elongated), the second lock rod 7 drives the lock tongue 6 to retreat from the lock hole 4, and the lock tongue 6 of the second lock rod 7 comes out of the lock hole 4, so that the two lock tongues 6 all come out of the lock hole 4, and the unlocking of the storage box lock mechanism is realized. Then the handle 3 is continuously pulled to the outside of the box body 1, the handle 3 drives the box cover 2 to open, and the inner pot 5 comes out of the box body 1.

[0042] Then the handle 3 is released, the handle 3 reversely rotates and resets under the action of the elastic force of the torsional spring 17, and the first lock rod 8 and the second lock rod 7 reversely move and reset under the action of the elastic force of the elastic element 16, and the lock tongue 6 extends from the side of the inner pot 5 again.

[0043] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be regarded as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
