An embodiment of the utility model provides a refrigeration plant for store and cold-stored frozen article, including the refrigeration box and the door body, refrigeration plant specifically can establish to refrigerator, freezer, gradevin etc. In the present embodiment, a description is developed taking a refrigerator as an example.

Referring to fig. 1 to 3, the refrigeration box includes an inner container 1, a slide rail 2 and a drawer assembly 3, a containing cavity 4 for storing articles is enclosed in the inner container 1, the slide rail 2 is assembled on an inner wall surface of the inner container 1, and the drawer assembly 3 is installed on the inner container 1 of the refrigeration box in a sliding manner by sliding fit with the slide rail 2, so that the drawer assembly 3 extends out of the containing cavity 4 or is accommodated in the containing cavity 4.

For convenience of description, the direction in which the drawer assembly 3 is pulled out from the accommodating chamber 4 toward the user is defined as front, the direction in which the drawer assembly 3 is returned from the user into the accommodating chamber 4 is defined as back, and the left-right direction and the up-down direction of the user are defined as the left-right direction and the up-down direction of the present embodiment, with reference to the user facing the door body.

The inner container 1 comprises a bottom wall 11, a top wall 12, a left side wall 13, a right side wall 14 and a rear wall 15, the bottom wall 11 and the top wall 12 are opposite up and down, the left side wall 13 and the right side wall 14 are opposite left and right, the rear wall 15 is positioned on one side of the inner container 1 far away from a user, four sides of the rear wall 15 are respectively connected with the left side wall 13, the right side wall 14, the top wall 12 and the bottom wall 11, the top wall 12, the left side wall 13, the right side wall 14 and the rear wall 15 jointly enclose the accommodating cavity 4, and the accommodating cavity 4 is provided with a front opening facing the user so as to be operated by the user. The door body is arranged on one side of the inner container 1 close to a user and used for opening or closing the front opening.

Referring to fig. 1 to 5, the drawer assembly 3 includes a drawer body 31 and rolling members 32 disposed on the drawer body 31, the rolling members 32 are disposed in pairs, each pair of rolling members 32 is disposed on the left and right sides of the drawer body 31 and moves synchronously, and the drawer body 31 can slide back and forth along the slide rail 2 by the rolling members 32 cooperating with the slide rail 2. The drawer body 31 has a retracted position housed in the housing chamber 4, and an extended position extending from the front opening out of the housing chamber 4. In use, a user pulls the drawer body 31 out of the front opening from the retracted position to the extended position to place an article in the drawer body 31 or take the article out of the drawer body 31 to complete the article storage and retrieval, and then pushes the drawer body 31 back to the retracted position from the extended position to return the drawer body 31 to be accommodated in the accommodating cavity 4.

With reference to fig. 6 to 8, the slide rail 2 includes an installation portion 21, a first guide rail 22 and a second guide rail 23, the slide rail 2 is assembled on an inner wall surface of the inner container 1 through the installation portion 21, specifically, the slide rail 2 is assembled on an inner wall surface of the left side wall 13 and/or the right side wall 14 of the inner container 1, the first guide rail 22 and the second guide rail 23 are respectively arranged in a pair in a left-right opposite manner, the first guide rail 22 and the second guide rail 23 are respectively connected with the installation portion 21, the first guide rail 22 and the second guide rail 23 respectively extend in a front-back direction, and are arranged at an interval from top to bottom, and the second guide rail 23 is located below the first guide rail 22. The rolling member 32 rolls back and forth between the first rail 22 and the second rail 23 to drive the drawer body 31 to move back and forth along the sliding rail 2, so that the drawer body 31 is pulled out of or pushed back into the accommodating cavity 4, and the drawer body 31 moves between the extended position and the retracted position.

Referring to fig. 6 to 8, the second guide rail 23 includes a horizontal section 231 at a front end thereof and an inclined section 232 at a rear end thereof, the inclined section 232 being connected to the horizontal section 231, the horizontal section 231 extending horizontally in a front-rear direction, and the inclined section 232 being gradually inclined downward from front to rear. When the user accesses the article and pushes the drawer body 31 back to the inclined section 232, the drawer body 31 can automatically move to the retracted position along the inclined section 232 under the action of the gravity of the user. Like this, the user only need exert very little power and can make drawer body 31 reset, has solved the problem that drawer body 31 can't return the position, has avoided leading to because of drawer body 31 can't return the position the door body striking drawer body 31, the cold and hot distribution in the refrigeration box is uneven, the emergence of the condition such as cold volume loss, labour saving and time saving, can also effectively prevent drawer body 31 from holding chamber 4 roll-off when the refrigeration box slightly leans forward, perhaps, drawer body 31 kick-backs and holds chamber 4 roll-off in when rolling member 32 supports and holds spacing arch 5.

Referring to fig. 6 to 9, the refrigeration box further includes a limiting protrusion 5, the limiting protrusion 5 and the rolling members 32 are correspondingly disposed and have the same number, the limiting protrusion 5 is disposed on the mounting portion 21 and protrudes from the mounting portion 21 toward the drawer body 31, that is, the limiting protrusion 5 protrudes along the left-right direction. The limiting protrusion 5 is disposed between the first guide rail 22 and the second guide rail 23, and specifically, the limiting protrusion 5 is located above the inclined section 232. When the drawer body 31 moves to the retraction position along the inclined section 232 under the action of the gravity of the drawer body, the rolling part 32 abuts against the limiting protrusion 5, and a gap is formed between the drawer body 31 and the rear wall 15 of the inner container 1, so that the drawer body 31 is prevented from moving to impact the rear wall 15 of the inner container 1 under the action of the gravity of the drawer body 31, and the drawer body 31 and the inner container 1 are prevented from being damaged.

Further, one side of the limiting protrusion 5 facing the rolling element 32 is a plane, so that the rolling element 32 is effectively braked, the impact force of the rolling element 32 on the limiting protrusion 5 is dispersed, and the processing is convenient.

Referring to fig. 9, in the present embodiment, the limiting protrusion 5 is a square column, which greatly reduces the processing difficulty and saves material. Further, the outer diameter of the limiting protrusion 5 is smaller than the outer diameter of the rolling member 32, so that under the condition that the connection strength of the limiting protrusion 5 and the mounting portion 21 is ensured, materials can be further saved, and the cost is reduced.

Furthermore, the limiting protrusion 5 is an elastic part, so that the rolling part 32 can play a role in buffering when impacting the limiting protrusion 5, impact noise is reduced, and the service life of the rolling part 32 and the limiting protrusion 5 is prolonged.

Referring to fig. 7, the periphery of the limiting protrusion 5 is further coated with an elastic washer 6, so that impact buffering of the rolling member 32 on the limiting protrusion 5 can be further increased, impact and damage to the limiting protrusion 5 caused by the fact that the rolling member 32 impacts the limiting protrusion 5 are reduced, and the service lives of the rolling member 32 and the limiting protrusion 5 are further prolonged.
