Description

Technical Field

[0001] The invention relates to the technical field of double-point locks, and in particular to a connector and a double-point lock having the connector. Background Art

[0002] In daily life, many door products are locked with double-point locks, especially in the automotive field, where the doors of center consoles and glove boxes are particularly common.

[0003] The double-point lock is installed on door products, which generally include a connector, a buckle and two connecting rods. The two connecting rods are respectively connected to the two working ends of the connector, and the buckle is against one of the connecting rods. When unlocking, the buckle pushes one of the connecting rods to move, and under the action of the connector, the other connecting rod also moves toward each other, so that the ends of the two connecting rods are separated from the threshold, thereby achieving unlocking. For example, patent CN201820688783 discloses a glove box lock and a car glove box, which specifically records that when opening the glove box, the buckle plate is pulled upward, and the buckle plate is against the baffle on one of the connecting rods, so that under the action of the connector, the two connecting rods move relatively close to achieve unlocking.

[0004] The existing double-point lock structure has the problems of difficult installation and troublesome maintenance. During the assembly process of the above-mentioned double-point lock, it is necessary to first assemble the entire connector, and then connect the two working ends of the connector to the connecting rod, and then install the entire connector together with the connecting rod inside the door, and then cover the door shell, and finally install the buckle on the door shell and connect it to one of the connecting rods. This assembly structure may cause the following problems: First, the connector is difficult to maintain. If the gear inside the connector lacks oil or is damaged or dusty and needs maintenance, the entire door needs to be disassembled before the coupling inside can be maintained; second, the service life is short. After a certain period of use, the baffle on the connecting rod becomes aged or fatigued as the main stress point, and the baffle is easily broken or partially damaged, resulting in problems such as the inability to open the door or the door opening is not smooth. Summary of the invention

[0005] The purpose of the present invention is to provide a connector with a compact structure in view of the deficiencies in the prior art. The present application also provides a double-point lock having the connector, which can solve the problem of short service life.

DETAILED DESCRIPTION

[0026] The present invention is further described in conjunction with the following examples.

[0027] For a specific embodiment of a connector of the present invention, see Figure 1 The connector includes a base 1 and a buckle handle. The connector of this embodiment is suitable for various door locks.

[0028] Please see Figure 3 , two spaced-apart mounting posts 11 are provided in the base 1, see Figure 4 The coupling also includes two gears 3, which are meshed and mirror-symmetrically sleeved on two mounting posts 11. Figure 1 and Figure 2 As shown, each gear 3 is provided with a working end 31 passing through the base 1, and a torsion spring 4 is provided between the mounting column 11 and the gear 3, one end of the torsion spring 4 is clamped with the mounting column 11, and the other end is clamped with the gear 3. Specifically, the top surface of each mounting column 11 is provided with a straight groove 111 facing downward, and the inner ring surface of each gear 3 is provided with a clamping groove 32 facing outward, one end of the torsion spring 4 is clamped in the straight groove 111, and the other end is clamped in the clamping groove 32. This fixing method of the torsion spring 4 can make the assembly process simpler, the torsion mechanism smoother, and the overall structure more compact.

[0029] Please see Figure 1 and Figure 2 The buckle includes a buckle body 2, and a pair of hinged parts 21 extend downward from both sides of the buckle body 2. The hinged parts 21 are hinged to the outer side of the base 1 through hinges. Specifically, the hinges are semi-arc convex strips 12 formed on two opposite outer sides of the base 1, and the two hinged parts 21 of the buckle body 2 are provided with semi-arc holes 22 that are engaged with the semi-arc convex strips 12. The semi-arc setting can effectively limit the rotation angle of the buckle and prevent the buckle from being damaged due to excessive rotation.

[0030] Please see Figure 2 The bottom surface of the buckle body 2 is provided with a push rod 23 for pushing the gear 3 to rotate, and a reset spring 5 is also provided between the buckle body 2 and the base 1. Among them, the head of the push rod 23 is spherical, which can effectively protect the gear 3 and make the unlocking process smoother. In addition, a cross convex strip 52 extends downward from the bottom surface of the buckle body 2, and a receiving groove 13 is provided at the end of the base 1 opposite to the cross convex strip 52. A protrusion 51 is fixedly connected in the receiving groove 13. One end of the reset spring 5 is sleeved on the cross convex strip 52, and the other end is sleeved on the protrusion 51. This fixing method of the reset spring 5 can effectively limit the reset spring 5 and prevent the reset spring 5 from deviating.

[0031] In this embodiment, in order to prevent foreign matter from falling between the two gears 3, see Figure 2 and Figure 4The connector further comprises a baffle 6, a reverse cone-shaped holding portion 61 extending downward from the bottom surface of the baffle 6, a plurality of buckles are arranged on the inner side wall of the base 1 and a holding hole 16 is opened on the bottom surface thereof, in the assembled state, the reverse cone-shaped holding portion 61 of the baffle 6 is inserted into the holding hole 16, and a plurality of buckles buckle the top surface of the baffle 6. This fixing structure of the baffle 6 can not only effectively prevent the baffle 6 from interfering with the gear 3, but also makes the assembly easier and the structure more compact.

[0032] In this example, see Figure 4 In order to further reduce the manufacturing cost, both gears 3 are incomplete gears. The design of the incomplete gear can be further designed according to the required opening range, and its manufacturing cost is lower than that of the full-tooth gear.

[0033] To further limit the rotation range of gear 3, see Figure 4 The bottom end surface of the base 1 is provided with a limiting hole 15 for the working end 31 of each gear 3 to pass through.

[0034] The working process of a connector of this embodiment is as follows: when unlocking, the buckle is lifted by external force, and the buckle rotates to drive the push rod 23 to push one of the gears 3 to rotate counterclockwise, and the counterclockwise rotating gear 3 will drive the gear 3 meshing with it to rotate clockwise, and the working ends 31 of the two gears 3 will move toward each other synchronously, so as to unlock the connector; when locking, the buckle is released, and the reset spring 5 pushes against the buckle body 2 to drive the buckle back, and at the same time, the torsion spring 4 releases the compression force to drive the gear 3 to rotate back, so that the working ends 31 of the two gears 3 are synchronously pulled apart and moved back to the original position, so as to lock the connector. Compared with the prior art, the connector structure of this application is simpler and more compact, and the buckle is directly used as the upper cover of the connector, which simplifies the components of the connector, reduces the volume of the connector, and reduces the manufacturing cost.

[0035] A specific implementation of a double-point lock of the present invention is shown in Figure 5 The double-point lock includes two connecting rods 7, and the double-point lock also includes the above-mentioned connector. The starting ends of the two connecting rods 7 are connected to the two working ends 31 of the connector, and the ends of the two connecting rods 7 are provided with locking tongues 71. The starting ends of each connecting rod 7 are provided with a clamping groove 72. In the assembled state, the working end 31 of the gear 3 is inserted into and fixed in the clamping groove 72.

[0036] Compared with the prior art, the double-point lock of this embodiment is easier to assemble on the door, and the maintenance and replacement of the coupling are more convenient. There is no need to place the coupling as a whole in the door, which simplifies the assembly steps and improves the assembly efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
