New type of safe button with lock
Technical field
The utility model relates to a kind of vehicular spare parts, and more particularly, it relates to a kind of safety belt for vehicle snap close.
Background technology
At present, safety belt lock catch on the automotive seat, connector between snap close body and the seat all is the vertical bar type, dead bolt inserts the snap close body for convenience, connector is all long, typical structure as depicted in figs. 1 and 2, safety belt lock catch comprises snap close body 1 and connector 9, connector 9 is the vertical bar shape, and whole safety belt lock catch is long, has made things convenient for dead bolt to insert snap close body 1, but connector 9 is longer, descendant's the health of fastening seat belts is just run into snap close body 1 easily, and particularly when safety misadventures such as automobile bumps, snap close body 1 will hurt the passenger.At the edge of connector 9, be provided with the groove of the location usefulness of two symmetries with the coupling end of seat.When connector 9 is connected with seat, use space washer 8, space washer 8 is provided with the packing ring bending 10 protruding upward with groove fit.Be provided with the packing ring bending 10 of protruding to space washer 8 another directions in the middle of two packing ring bendings 10, the knock hole on this packing ring bending 10 and the seat cooperates, and whole safety belt lock catch is had good positioning.Such location structure is cumbersome in the Assembly ﹠Disassembly safety belt lock catch.
Summary of the invention
Safety belt lock catch is long to be easy to hurt the passenger in order to solve, and safety belt lock catch location structure complexity, the deficiency of Assembly ﹠Disassembly trouble.The utility model provides a kind of new type of safe button with lock, and it is safe and reliable, makes things convenient for the insertion of dead bolt.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of new type of safe button with lock, comprise snap close body, connector, connector one end is connected on the snap close body, the other end connects on the seat, and the length overall of described new type of safe button with lock is 135mm ~ 150mm, connector be one step-like, be circular with the seat coupling end on the connector, the edge of coupling end is provided with the bending of location usefulness.Connector is a step-like snap close body that makes can not run into seat, makes things convenient for the insertion of dead bolt.Location between connector and the seat is to realize that by bending on the connector and the cooperating of knock hole on the seat location structure is simple, makes the Assembly ﹠Disassembly of safety belt lock catch convenient.The length overall of safety belt lock catch is made as 135mm ~ 150mm, and when automobile crashed, snap close damaged health with regard to being difficult for running into health.
As preferably, on the described step-like connector between two adjacent stations terraces excessive section is 150 ° with these two step surfaces.Excessively section makes the stressed more steady of connector.
As preferably, described snap close body is provided with and is used to the travel switch of reminding safety strap whether to buckle well.Whether travel switch inserts the automobile circuit control system and can remind the passenger to fasten seat belts.
Compared with prior art, the beneficial effects of the utility model are: (1) prevents that snap close from meeting the passenger and making the passenger uncomfortable, can prevent snap close injury passenger when running into safety misadventure, and dead bolt to insert snap close convenient; (2) location structure is simple, and the safety belt lock catch Assembly ﹠Disassembly is convenient.

The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: a kind of new type of safe button with lock (referring to accompanying drawing 3), length overall is 140mm, comprise snap close body 1, connector 2, connector 2 is a strip shape, through be after twice bending one step-like, on the step-like connector 2 between two adjacent stations terraces excessive section is 150 ° (referring to accompanying drawings 4) with these two step surfaces.Connector 2 one ends are connected on the snap close body 1, it is circular that the other end is, be provided with the bending 7 of a location usefulness at circular outward flange, bending 7 cooperates with knock hole on the seat 6 and realizes the location, by screw with a circular end and the seat 6 of connector 2 link together (referring to accompanying drawing 5).Snap close body 1 is provided with and is used to the travel switch 3 of reminding safety strap whether to buckle well, and travel switch 3 inserts the automobile circuit control system, and whether control system fastens seat belts according to the information reminding passenger of travel switch 3.
During installation, behind the knock hole on the bending 7 insertion seats 6 of connector 2, again the tapped bore on annulus hole on the connector 2 and the seat 6 is aimed at, and then it is fastening good to insert screw 5, so just safety belt lock catch and seat 6 is linked together and has had good positioning.During use, fasten one's safety belt, dead bolt is inserted in the snap close, if at this moment do not insert, travel switch 3 just is sent to the automobile circuit control system with this signal, and control system is just sent prompting and reminded the passenger to insert good safety strap.The utility model can prevent that snap close from hurting the passenger, make things convenient for dead bolt to insert snap close, and the safety belt lock catch Assembly ﹠Disassembly is simple.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
