Description

Lock catch

Technical Field

The utility model belongs to the technical field of machinery, and relates to a lock catch.

Background

At present, self-driving tour is an emerging oil outlet mode, and in order to meet the convenience of self-driving travel of people, people improve a traditional outdoor tent into a roof tent which can be installed on a roof, and the roof tent can be unfolded to be a place for people to rest when the vehicle is outdoors. The roof tent is mounted and fixed on the roof of the vehicle, and is folded and stored when not needed and forms a box-like shape. The conventional roof tent generally includes an openable cover and a tarpaulin provided in the cover and unfolded when the cover is opened, wherein the cover includes a bottom cover and a top cover hinged to the bottom cover, and the top cover is turned over to close or open the cover.

The bottom cover and the top cover are hinged by utilizing a hinge on the same side of the bottom cover and the top cover, and a lock catch is arranged on the outer cover in order to ensure that the outer cover can keep a closed state. For example, a tent fixing structure disclosed in patent application number 202121404192.4 comprises a support frame, wherein a lower cover plate is hinged to one side of the bottom of the support frame, an upper cover plate is hinged to one side of the top of the support frame, which is far away from the lower cover plate, a lock catch safety mechanism is arranged on the outer wall of the support frame, and a support mechanism is arranged on the outer wall of the support frame; the lock catch safety mechanism comprises a fixed seat arranged on two sides of the outer wall of the lower cover plate, one side of the outer wall of the fixed seat, far away from the support frame, is hinged with a breaking button, one side of the outer wall of the breaking button, far away from the fixed seat, is provided with a male button, two sides of the outer wall of the support frame are provided with female buttons matched with the male button, after the tent is covered and retracted, the breaking button arranged on the fixed seat is rotated, the breaking button drives the male button to eccentrically rotate, and then the male button and the female buttons are locked and fixed. When no article exists in the tent, the tent can be easily covered, and at the moment, the tent can be easily kept in a covered state by connecting the male buckle with the female buckle by operating the breaking buckle.

In practice, in order to prevent water leakage inside, a rubber strip is generally disposed on the upper side of the bottom cover, and when the outer cover is closed, the top cover and the outer cover are buckled by a lock catch, so that the top cover can squeeze the rubber strip to deform to realize sealing and water leakage prevention. However, when the tent is not used for a long time, the rubber strip is likely to be in a compressed state all the time, and the elastic restoring capability is weakened in this state, when the user opens the tent outer cover and wants to close again, since the top height of the rubber strip is already low, the height of the female buckle is also low compared with the previous one when the top cover is abutted against the bottom cover, and the height after the male buckle is finally buckled is always unchanged, so that the buckling of the lock buckle is relatively loose, and therefore the top cover cannot be tightly abutted against the rubber strip to ensure the tightness.
