Description

Caravan screen window safety-protection lock

Technical field

The utility model is related to a kind of safety-protection locks, more particularly to a kind of caravan screen window safety-protection lock simple in structure, at low cost.

Background technology

Existing caravan screen window security protection lock construction is more complicated, of high cost, is unfavorable for promoting and applying, and therefore, is badly in need of a kind of It is simple in structure, at low cost, the mechanical safety-protection lock being suitable on car door.

Utility model content

The purpose of this utility model is to provide a kind of caravan screen window safety-protection locks simple in structure, at low cost.

To achieve the goals above, caravan screen window safety-protection lock provided by the utility model includes pedestal, front handlebar, afterwards handle Hand, shifting block, tongue bolt and elastic component, the front handlebar and rear handle are in be rotatably arranged in the both sides of the pedestal, and institute respectively It states front handlebar and the rear handle is fixedly connected with the shifting block, the tongue bolt is slidingly arranged in the pedestal, the bullet The both ends elasticity of property part contacts at the tongue bolt and the base vivo wall；The shifting block is equipped with top, and the tongue bolt is equipped with and supports Top bevel, so as to drive the tongue bolt retraction by top is slided and supports inclined-plane described in conflict when the shifting block rotates In the pedestal.

Compared with prior art, a shifting block is fixed on the front handlebar and rear handle due to the utility model, described Top is set on shifting block, and a tongue bolt is slidably set on the pedestal, is arranged on the tongue bolt and supports inclined-plane, pass through Therefore the top when rotating front handlebar or rear handle, can drive with the effect supported inclined-plane and supported in sliding The shifting block realizes locking or unlock to drive the tongue bolt to slide；Thus, entire lock body structure very simple, adult is low, Be conducive to promote and apply.

Preferably, the edge of the shifting block extends the first tongue body, the top is set on first tongue body.

Specifically, the second tongue body is extended in one end of the tongue bolt, and the inclined-plane of supporting is set to second tongue body Edge.

Preferably, the pedestal is equipped with sliding groove, the tongue bolt is slidingly arranged in the sliding groove.

Preferably, the elastic component is compressed spring, the compressed spring, which provides one, makes the tongue bolt stretch out the pedestal Elastic force.

Preferably, the pedestal includes rear pedestal and front pedestal, the rear pedestal is screwed with the front pedestal Connection, the front handlebar are set in the rear pedestal, and the rear handle is set in the front pedestal.

Description of the drawings

Fig. 1 is the stereogram of the utility model caravan screen window safety-protection lock.

Fig. 2 is the exploded view of the utility model caravan screen window safety-protection lock.

Specific implementation mode

For the technology contents of the utility model, construction feature, the effect realized is described in detail, below in conjunction with embodiment And attached drawing is coordinated to be explained in detail.

As shown in Figure 1 and Figure 2, the utility model caravan screen window safety-protection lock 100 includes pedestal 1, front handlebar 2, rear handle 3, dials Block 4, tongue bolt 5 and elastic component 6, the front handlebar 2 and rear handle 3 are in be rotatably arranged in the both sides of the pedestal 1, and institute respectively It states front handlebar 2 and the rear handle 3 is fixedly connected with the shifting block 4, the pedestal 1 is equipped with sliding groove 11, and the tongue bolt 5 slides Ground is set in the sliding groove 11.The both ends elasticity of the elastic component 6 contacts at 1 inner wall of the tongue bolt 5 and the pedestal；Institute It states shifting block 4 and is equipped with top 42, the tongue bolt 5 is equipped with and supports inclined-plane 52, so that the shifting block 4 passes through the top when rotating 42 slidings are supported inclined-plane 52 and are driven in pedestal 1 described in 5 retraction of tongue bolt described in contradicting.

Specifically, the edge of the shifting block 4 extends the first tongue body 41, and the top 42 is set to first tongue body On 41.Extend the second tongue body 51, the side supported inclined-plane 52 and be set to second tongue body 51 in one end of the tongue bolt 5 Edge.

The elastic component 6 is compressed spring, and the compressed spring provides a bullet for making the tongue bolt 5 stretch out the pedestal 1 Property power.

The pedestal 1 includes rear pedestal 1a and front pedestal 1b, the rear pedestal 1a and the front pedestal 1b solid by screw Fixed connection, the front handlebar 2 are set on the rear pedestal 1a, and the rear handle 3 is set on the front pedestal 1b.

Compared with prior art, since the utility model fixes a shifting block 4 on the front handlebar 2 and rear handle 3, in institute Setting top 42 on shifting block 4 is stated, and a tongue bolt 5 is slidably set on the pedestal 1, is arranged on the tongue bolt 5 and supports Inclined-plane 52, by the top 42 with the inclined-plane 52 of supporting in the effect supported of sliding, therefore, in rotation front handlebar 2 or Afterwards when handle 3, the shifting block 4 can be driven to drive the tongue bolt 5 to slide, realize locking or unlock；Thus, entire lock body Structure very simple, adult is low, is conducive to promote and apply.

Above disclosed is only the preferred embodiments of the utility model, cannot limit the utility model with this certainly Interest field, therefore equivalent variations made according to the patent scope of the utility model still fall within the utility model and are covered Range.
