Description

A kind of simple door latch

Technical field

The utility model belongs to the building engineering construction field, is specifically related to a kind of simple door latch.

Background technology

In the building engineering construction process, the interim door of construction elevator, the interim door in washroom and interim electric door etc., these doors should keep normally closing, but can not be locked with lockset, thereby door bolt just seems still for important.

Door bolt commonly used at present has following several:

First kind of latch is to adopt sheet iron to add the common latch that " 7 " shape inserted link is formed, and this latch adopts iron sheet thin, and under the higher environment of this door leaf switching frequency in building site, durability is relatively poor, and is fragile simultaneously.

Per two kinds of latches are night bolts that a kind of stainless steel is made, and this latch is made exquisite, but cost is higher, once it is big to damage the maintain and replace cost, are not suitable for equally using under this open-air atmosphere in building site.

Therefore, need a kind of simple door latch to address the above problem.

The utility model content

The utility model purpose: the utility model is in the building engineering construction process in the prior art, and the defective of interim door bolt provides a kind of simple and easy, durable simple door latch.

Technical scheme: for solving the problems of the technologies described above, simple door latch of the present utility model adopts following technical scheme:

A kind of simple door latch comprises key seat and pin rod, and the both sides of described pin rod are provided with stopper slot, and the both sides of described key seat are provided with the projection that matches with described stopper slot, and described projection is inserted described stopper slot.

Further, described pin rod is provided with the stopping means of described key seat.Avoid pin rod to come off.

Further, described stopping means is arranged on the two ends of described pin rod.Key seat is limited in the pin rod.

Further, described stopping means and described pin rod are for removably connecting.Key seat for convenience detach and pin rod.

Further, described key seat and pin rod are shape.Shape extremely is easy to get in the building site, gathers materials on the spot during making, draws materials easily, effectively saves engineering cost.

Beneficial effect: simple door latch of the present utility model adopts the design that horizontally slips of key seat and pin rod, and slip freely, and is simple in structure, durable, improved the durability of latch, improved an interior environmentAL safety.
