Description

TECHNICAL FIELD

[0001] The utility model relates to an automobile lock technical field, concretely is a glove box lock mechanism. BACKGROUND

[0002] The glove box is the storage box that sets up in the vice driver position of car, opens and locks tightly through the locking device control glove box. The current glove box locking device includes the lock rod subassembly and the hand component, drives the lock rod subassembly horizontal movement through the hand component, and the opening of glove box is completed. The lock mechanism in the conventional lock rod subassembly drives the left and right lock rods (such as Figure 1 The structure occupies greater in width direction, and the whole rotating shaft structure is exposed, is not beautiful, and transmission linearity is not very good, influences the operation experience. UTILITY MODEL CONTENT

[0003] The utility model discloses a glove box lock mechanism to solve the problem in the above background technology.

[0004] To realize above -mentioned purpose, the utility model provides the following technical scheme: a glove box lock mechanism, including two left and right symmetrical setting lock rods, still including the rotary cylinder, the inside end of lock rod is equipped with the connecting rod of concentricity, the inside end of connecting rod is inserted to rotary cylinder respectively, the both ends of rotary cylinder are symmetrically provided with helical groove, the inside outside of connecting rod's inside end is fixedly installed with the radial pin, and the pin is inserted into helical groove and is slidably connected with it, and the tail end of lock rod is connected with the end portion of rotary cylinder, and the spring is sleeved on the connecting rod.

[0005] Preferably, the diameter of the lock rod is greater than the diameter of the connecting rod, and the tail of the lock rod is provided with a concentric flange.

[0006] Preferably, the outer diameter of the pin is greater than the width of the helical groove.

[0007] Compared with the prior art, the utility model has the beneficial effects that: the transmission of the utility model can be realized on an axis, saving space, making the size of the entire lock mechanism smaller than conventional glove box locks on the market, and the transmission of the device is in the form of screw rotation, making the transmission smoother and more linear.
