Problems solved by technology

[0003] When in use, the magnet liner is easily damaged or falls off due to moisture, causing cold air to leak out, reducing the refrigeration degree of the refrigerator, and affecting the freshness of food, so it often causes troubles for users; After the box is closed by the magnetic force of the magnet liner, the door leaf needs to be pulled in the opposite direction to open the door leaf. Therefore, when two hands hold dishes and articles and want to put them into the refrigerator, it will cause inconvenience in opening ; In addition, as the size of the refrigerator increases, the magnetic attraction force formed by the magnet liner and the magnetic body in the cabinet is greater, and for the elderly and young children with limited mobility or insufficient strength, it will be difficult to use. Causing distress

Embodiment Construction

[0040] Please refer to Figure 1 to image 3 As shown, the present invention is a door switch device for a refrigerator, comprising a male component 1 and a female component 2;

[0041] The male assembly 1 is composed of a male fixing seat 11 , a male operating sleeve 12 , a male card hook seat 13 and a telescopic rod body 14 .

[0042] The male fixing seat 11 is provided with a plurality of claws 112 with a stop edge 113 protruding from the cylinder of the disc seat, and a locking groove 114 is provided at the bottom of the cylinder, as shown in FIG. 1C .

[0043] The male operating sleeve 12 is a cylindrical sleeve body; several positioning grooves 121 are formed on the wall of the cylinder, and a conical cylinder 122 is recessed on the top surface, as shown in FIG. 1A .

[0044] The male card hook seat 13 is provided with several hook claws 132 with grooves 134 on the upper side of the ring-shaped seat surface, and the inner side of the end 133 forms a slope 135 and a blocki...

Abstract

The invention is a door leaf switch device, it embeds several male components on the edge of the door leaf, the edge of the box is arranged with several correspondent female components; the male component is made up of male fixed base, male operating cylinder, male clamp hook and link; the female component is made up of female fixed base, female operating cylinder and female clamp hook cover; when the leaf moves to the box, the male component uses the link to push into the female component, thus the hook of the female component can holds the female ring slots at front of the link, thus the door leaf closes the box; when pressing the door leaf, the male operating cylinder and the female operating cylinder push each other, then the front and back male and female slot and the hook of male component quit to the male component, thus the leaf can be opened.

Description

technical field [0001] The invention relates to a door leaf switch device. Background technique [0002] The existing opening and closing method of the door leaf of the refrigerator is to set a magnet liner on the inner periphery of the door leaf, and a magnetic body that can attract the magnet liner is built in the periphery of the opening of the box. Make the door leaf close to close the box body. [0003] When in use, the magnet liner is easily damaged or falls off due to moisture, causing cold air to leak out, reducing the refrigeration degree of the refrigerator, and affecting the freshness of food, so it often causes troubles for users; After the box is closed by the magnetic force of the magnet liner, the door leaf needs to be pulled in the opposite direction to open the door leaf. Therefore, when two hands hold dishes and articles and want to put them into the refrigerator, it will cause inconvenience in opening ; In addition, as the size of the refrigerator increa...
