Abstract

A guard door handrail belongs to the field of household supplies and comprises two outer frames arranged in parallel; a net-like stretching door is connected in the outer frames; fixed parts are also connected with two sides of the outer frames; the guard door handrail also comprises a chute frame arranged between the two outer frames and connected to the upper part of the stretching door. The chute frame is formed by mutually connecting a large chute frame, a middle chute frame and a small chute frame. The connecting strength of the net-like stretching door can be effectively improved, so the pressing resistance and anti-collision strength can be improved. The chute frame is divided into multiple sections for connecting, so the volume after the net-like stretching door is contracted can be ensured, hands of a user can be effectively protected from being clamped, and the unfolding and folding processes of the net-like stretching door can be more smooth.

Description

A kind of protective door sill

Technical field

The present invention relates to household articles, especially for the Domestic door hurdle in limiting child or pet activity zone.

Background technology

A lot of protective door sills are arranged on market, and form is different, various in style.A kind of mesh door hurdle is wherein just arranged, and because its stretching structure is simple, the hurdle gathering of whole door or expansion are all very convenient, and by the customer, are liked rapidly.

But after long-term the use, the mid portion that the customer finds the mesh door hurdle is because lacking and being fixedly connected with of other mechanisms, so compressive strength is low, and the reasons in structure on mesh door hurdle own, mid portion and two ends are difficult to keep at grade, long mesh door hurdle particularly, mid portion, compressive strength is lower.

Summary of the invention

Purpose of the present invention, be to solve the problems of the technologies described above, and a kind of bonding strength that improves the mid portion on mesh door hurdle is provided, and improve its safety.

Technical solution of the present invention is: a kind of protective door sill, comprise two housings that be arranged in parallel, connect netted stretching door in housing, housing is gone back connection fixture on both sides, also comprise and being arranged between two housings, and being connected to the chute frame on the door top that stretches, described chute frame is that large chute frame, middle chute frame and little chute frame interconnect and form.

Because being connected of chute frame and the netted door that stretches arranged, can heighten a netted bonding strength stretched.Because the whole netted top that stretches door all is connected in the chute frame, guaranteed that like this mid portion of chute frame can not lower compressive strength because having mechanism to connect.And all by the chute frame, protected because of the top of the netted door that stretches, can effectively prevent tong, improve safety.

As preferably, described large chute frame arranges in its end with the arc hook of thinking middle chute frame guiding.

As preferably, described middle chute frame its end arrange with arc hook, be connected and along in the extension that extends of chute edge edge; Described middle chute frame also is provided with the retaining groove of thinking little chute frame guiding.

As preferably, offer the through hole in order to be connected with the netted door that stretches on described little chute frame.

As preferably, between described little chute frame and netted stretching door, prerotation vane is set.

As preferably, described prerotation vane comprises the bending part on body, connecting hole, stator and connection body.

Beneficial effect of the present invention is:

(1) because all being arranged in the chute frame on the netted top that stretches door, can effectively improve like this bonding strength of the netted door that stretches, thereby improve the crashproof intensity of resistance to compression.

(2) the chute frame is divided into multistage and connects, and has ensured the volume after the netted door that stretches shrinks, and can effectively protect the user can be by tong, and the expansion of netted stretching door or gathering process are more smooth-going.

The accompanying drawing explanation

Fig. 1 is embodiment of the present invention protective door sill structural representation;

The structural representation that Fig. 2 is the chute frame;

The structural representation that Fig. 3 is prerotation vane.

In figure: 1-housing, the netted stretching door of 2-, 3-fixture, 4-chute frame, the large chute frame of 41-, chute frame in 42-, the little chute frame of 43-, 411-arc hook, 421-extension, 422-retaining groove, 431-through hole, the 5-prerotation vane, 51-connecting hole, 52-bending part, 53-stator, 54-body.

The specific embodiment

Below in conjunction with accompanying drawing, with embodiment, the invention will be further described.

This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this manual, but as long as all are subject to the protection of Patent Law in claim scope of the present invention.

Embodiment 1, as Figure 1-3, and a kind of protective door sill, comprise two housings that be arranged in parallel 1, the both ends up and down of housing 1 connect netted stretching door 2, and housing is gone back connection fixture 3 on 1 both sides, and described fixture 3 can be fixed on needed position by whole protective door sill.Protective door sill also comprises and being arranged between two housings 1, and is connected to the chute frame 4 on door 2 tops that stretch.Described chute frame 4 forms for large chute frame 41, middle chute frame 42 and little chute frame 43 interconnect.Large chute frame 41 is fixedly connected with housing 1 on one side, and large chute frame 41 connects with the arc hook (411) of thinking middle chute frame 42 guiding in its end one.Described middle chute frame 42 connects in its end one the extension 421 that in the also edge be connected with arc hook (411), chute frame 42 edges extend; The end of extension 421 also arranges fillet, extension 421 slides more smooth and easyly in arc hook 411 like this, and fillet is consistent with the radian of arc hook 411, and arc hook 411 not only can be done guide effect for extension 421, can also block extension 421, prevent middle chute frame 42 derailings.Described middle chute frame 42 also is connected with the retaining groove 422 of thinking little chute frame 43 guiding.Retaining groove 422 is formed by connecting by transverse slat and riser, and riser is fixedly connected with middle chute frame 42, and between transverse slat and middle chute frame 42, distance is than the large 1 ~ 2mm of the thickness of little chute frame 43.On described little chute frame 43, offer in order to netted stretching door 2 through holes that are connected 431.By the interior bookbinding bolt of through hole 431, can netted stretching door 2 is fixing with little chute frame 43, but do not need all netted upper ends that stretch door 2 all to be fixedly connected with little chute frame 43, only need fixing several parts.

Because the width of little chute frame 43 can not be consistent with the width of the netted door 2 that stretches, otherwise can make both always touch and be plugged together.If but the width of little chute frame 43 is greater than netted stretching door 2, netted stretching door 2 is when launching, reasons in structure because of the netted door 2 that stretches, the middle part of stretching door 2 can be offset, also will encounter little chute frame 43, so between the junction of netted stretch door 2 and little chute frame 43, prerotation vane 5 is set, described prerotation vane 5 comprises body 54, offer connecting hole 51 on body 54, connecting hole 51 coaxially is connected with little chute frame 43, netted stretching door 2 for guaranteeing.Bending part 52 is set on the end of body 54, and bending part 52 touches little chute frame 43 for stopping netted stretching door 2.The both sides of body 54 also arrange leg-of-mutton stator 53, and stator 53 can be inserted in netted stretching door 2, in order to fixed body 54.
