Description

Portable refrigerator

Technical Field

The invention relates to the technical field of refrigeration equipment, in particular to a portable refrigerating box.

Background

A refrigerator is a common life tool for refrigerating items; with the continuous improvement of living standard, people often travel or participate in outdoor activities, and especially in summer, people usually use the cold storage box to carry cold drinks so as to achieve the purposes of relieving summer heat and cooling.

The existing refrigerating box generally comprises a box body, wherein a sliding door is hinged to the box body, and a coolant is placed in the box body; the refrigerating box is used for storing the articles to be refrigerated and storing the articles to be refrigerated. However, in the above technical solution, if the refrigerator is moved, the refrigerator usually shakes, which may cause the sliding door to be opened by mistake to some extent, thereby causing a phenomenon that the articles roll out of the refrigerator, etc., and causing a certain loss to the user.

Therefore, how to avoid the mistaken opening of the sliding door in the process of moving the refrigerator and prevent articles from sliding down from the refrigerator is a problem which needs to be solved urgently at present.

Disclosure of Invention

The invention aims to provide a portable refrigerating box to solve the problem that articles can not slide from the refrigerating box due to mistaken opening of a sliding door in the process of moving the refrigerating box in the prior art.

In order to achieve the above purpose, the basic scheme of the invention is as follows: the portable refrigerating box comprises a box body, wherein a sliding door is hinged to the box body, an object placing plate and a cold storage bag storing a cold storage agent are arranged in the box body, the upper surface of the box body is fixedly connected with a lifting handle, the lifting handle comprises an arc-shaped holding rod and a hollow handle shell, two ends of the holding rod are connected in the handle shell in a sliding mode, two ends of the holding rod are fixedly connected with limiting plates, and a reset spring is connected between each limiting plate and the handle shell; the sliding door is provided with a through hole, a rotary disc is rotatably connected in the through hole, the rotary disc is coaxially connected with a rotary shaft, the rotary shaft is fixedly connected with a ratchet wheel, one side of the rotary disc, which is far away from the box body, is fixedly connected with a door opening handle, the rotary disc is fixedly connected with an extension plate which is positioned at the inner side of the sliding door, one side of the extension plate, which is far away from the sliding door, is fixedly connected with an extension; the side wall of the box body is of a hollow structure, the side wall of the box body is provided with an opening for the ratchet wheel, the extension plate and the clamping plate to pass through, the inner surface of the side wall of the box body is provided with a supporting groove for the end part of the rotating shaft to extend into, the inner surface of the side wall of the box body is provided with a clamping groove for the clamping plate to extend into, and the inner surface of the side wall of the box body is fixedly connected with an extrusion; the side wall of the box body is internally provided with a clamping mechanism for clamping the ratchet wheel, and the two limiting plates are connected with a pull rope for triggering the clamping mechanism.

The working principle of the scheme is as follows: in the initial state, the refrigerator is in the closed state. When needing to open, it drives the carousel and rotates to rotate the handle that opens the door, the carousel drives the extension board, extension rod and block board rotate, when the block board rotates to when blocking groove notch is relative, under the elastic action of extrusion spring, outwards pop open the ratchet to the box, the ratchet drives pivot and carousel and keeps away from the box and removes, the carousel drives the extension board, extension rod and block board are kept away from the box and are removed, break away from with the block groove along with the block board, the pulling handle that opens the door, make the ratchet, the pivot, extension rod and block board shift out from the opening, the sliding door breaks away from with the box mutually, put the article that will wait to refrigerate in the refrigerator-freezer, then close the sliding door.

If the refrigerating box needs to be moved, the lifting handle is held, and the refrigerating box is moved to a specified position; at the in-process that removes the fridge, the effect that the holding rod received the external force, for the ascending removal of handle casing, the holding rod drives limiting plate rebound, and the limiting plate drives the stay cord and removes, and stay cord pulling block mechanism carries out the block to the ratchet, prevents to take place to rotate at the in-process ratchet of the fridge that removes, avoids the sliding door mistake to open.

Compared with the prior art, the technical scheme has the advantages that: 1. through the arrangement of the rotary disc, the clamping plate, the ratchet wheel, the extrusion spring and the clamping groove, the sliding door can be clamped with the box body, and cold air in the box body is prevented from leaking; 2. through setting up the lifting handle, can realize carrying out the block at the in-process that removes the box to the ratchet, avoid the ratchet to take place to rotate at the in-process that removes to cause sliding door and box to break away from mutually, lead to the problem of article landing from the box.

Further optimize, the block mechanism includes the pawl subassembly, the pawl subassembly is including being X form articulated first pawl, the second pawl, box lateral wall internal surface rigid coupling has the bracing piece that is used for supporting first pawl, the second pawl, the equal rigid coupling in pawl subassembly both sides has the fixed block, all be connected with between fixed block and the pawl subassembly and be used for making the pawl subassembly to keeping away from the elastic component that the ratchet direction removed, the one end that first pawl and second pawl are close to the ratchet all is equipped with the driven part with ratchet engaged with mutually, the other end of first pawl and second pawl all articulates there is the pawl connecting rod, the end of two pawl connecting rods is articulated mutually, the stay cord links to each other with two pawl connecting rod ends. The first pawl and the second pawl are clamped with the ratchet wheel only when the lifting handle is pulled, so that the ratchet wheel is locked and limited, and the sliding door is prevented from being opened by mistake; when the lifting handle stops being pulled, the first pawl, the second pawl and the ratchet wheel are disengaged from the clamping relation, the sliding door can be normally opened, and articles can be taken according to requirements.

Further optimizing, the box upper surface is equipped with the recess of placing that is used for placing article. When the refrigerator is used outdoors, the cup or the beverage can be placed in the placing groove, and the cup or the beverage can is prevented from being toppled.

Further optimization, the surface of the door opening handle is provided with a plurality of anti-skidding bulges. The phenomenon of skidding when the user pulls the door opening handle is prevented.

Further optimizing, the holding rod is sleeved with an anti-slip sleeve. The friction between the hand of the user and the holding rod is increased, and the phenomenon of falling off in the process of moving the box body is prevented.

Further preferably, the elastic member is a tension spring. The extension spring is common spare part, is favorable to the maintenance work in later stage.
