Description

A kind of double-safety children's pet door hurdle

Technical field

The utility model relates to children's pet door hurdle technical field, particularly relates to a kind of double-safety children pet door hurdle.

Background technology

Now there are underage child or pet in many families, sometimes in order to limiting child and pet are in scope of activities placed in the middle, can install children's pet door hurdle, children and pet are isolated in the side on a hurdle in the narrower place in some passageway or doorways etc.Because children's pet door hurdle is mainly used for limiting child and pet, therefore the comparatively simple door lock of a Structure of need, current children's pet door hurdle generally only has simple one structure heavily insured, pet and children accidentally can untie these door-lock opening door hurdles, and this just makes the safety having had a strong impact on children's pet door hurdle.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, the double-safety children pet door hurdle providing a kind of safety high.

In order to realize above object, the technical field that the utility model adopts is:

A kind of double-safety children's pet door hurdle, comprise a body, the latch being with slider is provided with in doorframe and door lock box described in the door lock box be arranged on a body, its slider is positioned at locking box outer surfac, drive latch along its axial interior external extension by slider, described doorframe offers and coordinates this lock bolt hole, locked by latch and pin-and-hole between Men Tiyu doorframe, described door lock box outer surfac is also rotatably connected to knob, the point of rotation of described knob and the sliding path of slider are located along the same line, the point of rotation of this knob also departs from its center simultaneously, the knob of described door lock box outer surfac is by rotating the movement controlling slider, thus realize control gate body switch.

Further, on described latch, cover has the back-moving spring making latch automatic spring.

Further, the rotating shaft of described knob extends in door lock box, and on the other end of rotating shaft, form the rotating limit block for limiting knob angle, described rotating limit block is the structure of half rectangle half kidney-shaped simultaneously.

The beneficial effects of the utility model are: in the double-safety children pet door hurdle of the present embodiment, its door lock box has the latch of band slider, drive latch along its axial interior external extension by sliding slider, when stretching into the pin-and-hole on doorframe when latch, just can realize the locking between Men Tiyu doorframe.Its knob is connected to the external surface of door lock box, the sliding path of its point of rotation and slider is located along the same line, and the central point of the point of rotation and knob departs from, this just makes knob knob occupying length and can change thereupon slider sliding path in its turn process, knob occupy the larger slider of length to slide stroke less, just can be fixed when it occupies the position of slider when length is in maximum value and cannot slide, thus latch is remained at door body and doorframe locking in pin-and-hole, by realizing the effect of double locking with upper type, improve the unlocking difficulty on door hurdle, effectively children and pet are isolated in Men Lan side by simple structure, improve the safety on door hurdle, children or pet are fixed on specific place, children or pet is avoided easily to beat opening door body, leave particular place to cause danger.

Detailed description of the invention

Now with specific embodiment, the utility model technical scheme required for protection is described in further detail by reference to the accompanying drawings.

Shown in accompanying drawing 1 to accompanying drawing 7, in the present embodiment, the door lock box 3 that double-safety children pet door hurdle comprises a body 1, doorframe 2 and is arranged on a body 1, being provided with in locking box can along the latch 31 of its axial interior external extension, this latch 31 is formed with slider 311, the external surface that its slider 311 is positioned at locking box comes and goes along the axis of latch 31 and slides, and latch 31 can be driven in the process that slider 311 slides to stretch; The correspondence position of doorframe 2 offers the pin-and-hole 21 coordinating latch 31, when latch 31 stretches out in insertion pin-and-hole 21, can mutually lock between door body 1 and doorframe 2, realize the first heavy locking function on door hurdle.On latch 31, also overlap upper reset spring 312 in the present embodiment makes latch 31 can automatic spring.

Knob 32 is also rotatably connected at the external surface of door lock box 3, the point of rotation of knob 32 and the sliding path of slider 311 are on same straight line, when slider 311 cunning contacts with knob 32, knob 32 can stop that slider 311 makes it cannot continue to slide along the direction at knob 32 place, thus make knob 32 define slider 311 slide stroke, the point of rotation of knob 32 departs from its side being centrally located at knob 32, be rotated in length occupied in the sliding path of slider 311 can change when knob 32 rotates thereupon, in the present embodiment after the length direction of knob 32 is overlapping with sliding path, the length of knob 32 occupied by sliding path is maximum value, the stroke of slider 311 is made latch 31 retract by knob 32 restriction thus is locked by latch 31, realize the second heavy locking function on door hurdle, by realizing the effect of double locking with upper type, improve the unlocking difficulty on door hurdle, effectively children and pet are isolated in Men Lan side by simple structure, improve the safety on door hurdle.In the present embodiment, the rotating shaft of knob 32 extends in door lock box 3, on the other end of rotating shaft, form the rotating limit block 321 for limiting knob 32 rotational angle simultaneously, the structure of rotating limit block 321 in half rectangle half kidney-shaped, when behind the half rectangle side and door lock box 3 contact internal walls of rotating limit block 321, rotating limit block 321 will be blocked and cannot be rotated further by door lock box 3 inwall, thus restriction knob 32 rotates.

Children and pet are isolated in Men Lan side by simple structure by the double-safety children pet door hurdle of the present embodiment effectively, improve the safety on door hurdle, children or pet are fixed on specific place, avoid children or pet easily to beat opening door body, leave particular place and cause danger.

The embodiment of the above is only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model.Any those of ordinary skill in the art, do not departing under technical solutions of the utility model ambit, the technology contents of above-mentioned announcement all can be utilized to make more how possible variation and retouching to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Therefore all contents not departing from technical solutions of the utility model, the equivalent equivalence change that the thinking according to the utility model is done, all should be covered by protection domain of the present utility model.
