Abstract
A spring bolt comprises a bolt body. The bolt body is made of powder metal by means of integral compression molding, a guide oblique plane is formed at the front end of the bolt body, a connecting hole which is used for being connected with a lock cylinder is formed in the rear end surface of the bolt body, and guide grooves which are used for being matched with a guide portion of a lock are respectively formed in two side surfaces of the bolt body. The spring bolt has the advantages of simple structure, low cost and the like.
Description
Technical field
The utility model relates to a kind of dead bolt.
Background technology
Known, door lock mainly is made up of lock core and dead bolt, lock core is connected with dead bolt and can be entered in the latch hole to drive dead bolt by operational motion, realize the action of locking a door of door, existing dead bolt is mostly made by metal material, need to adopt processing such as lathe mills, boring, car in manufacturing process, operation is loaded down with trivial details and cost is high, can't meet the need of market.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, with low cost and one-time formed dead bolt is provided.
The purpose of this utility model realizes by following technical solution:
A kind of dead bolt is characterized in that: comprise the tongue body by the compression moulding of powder metallurgy one, lead-in chamfered, rear end face that the tongue body front end is formed with inclination are formed with the connecting hole that is connected for lock core.
Further, described tongue body two sides are formed with the gathering sill that matches for the lock body guide part respectively.
Further, the cross section of described gathering sill is arc.
Further, the cross section of described gathering sill is rectangle.
Further, described connecting hole is circle, rectangle or triangle.
The utlity model has following beneficial effect:
Dead bolt of the present utility model adopts the compression moulding of powder metallurgy one, has simple, the with low cost and production efficiency advantages of higher of technology, the bootable tongue body of the lead-in chamfered of tongue body enters in the latch hole swimmingly, the connecting hole of tongue body can be connected with lock core by pull bar, pull bar one end is plugged in the connecting hole, the other end is connected with lock core, and assembling fast, conveniently; The gathering sill of tongue body can guide the tongue body precision maneuver.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is elevation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
A kind of dead bolt, comprise the tongue body 1 by the compression moulding of powder metallurgy one, lead-in chamfered 12, rear end face that tongue body 1 front end is formed with inclination are formed with for the circular connecting hole 13 that is connected with lock core, tongue body 1 two sides are formed with the gathering sill 11 that matches for the lock body guide part respectively, and the cross section of gathering sill 11 is circular arc.
The above, it only is preferred embodiment of the present utility model, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
