Description

Technical Field

[0001] The utility model relates to the field of refrigerator installation, and particularly to a limiting device. Background Art

[0002] An embedded refrigerator is a refrigerator embedded in a cabinet. An installation groove is formed in the cabinet, and the embedded refrigerator is located in the installation groove. The cabinet door of the embedded refrigerator is located at the opening of the installation groove and is flush with the edge of the installation groove opening, so that the embedded refrigerator and the cabinet form an integrated structure in appearance. Correspondingly, the cabinet door of the embedded refrigerator is usually opened and closed by pressing.

[0003] When the embedded refrigerator is in the installation groove, on the one hand, it is supported on the ground, and on the other hand, it keeps a certain distance from the wall. When the cabinet door is pressed, if the friction force between the embedded refrigerator and the ground is insufficient, the embedded refrigerator is likely to slide towards the wall, resulting in a step between the cabinet door and the edge of the installation groove opening. This not only reduces the integration degree of the embedded refrigerator and the cabinet in appearance, but also easily hinders the opening and closing of the cabinet door. Summary of the Utility Model

[0004] Based on this, in view of the problem that the embedded refrigerator is prone to sliding in the cabinet, it is necessary to provide a limiting device.

[0005] A limiting device includes:

[0006] A first limiting seat for abutting against the wall;

[0007] A second limiting seat for abutting against the refrigerator;

[0008] A first swing rod, with both ends of the first swing rod rotatably arranged on the first limiting seat and the second limiting seat respectively; and

[0009] A first telescopic rod, with one end of the first telescopic rod fixed on the first limiting seat and the other end of the first telescopic rod slidably arranged on the second limiting seat.

[0010] In the utility model, a sliding groove is formed in the second limiting seat, a sliding block is arranged at the end of the first telescopic rod, and the sliding block is slidably arranged in the sliding groove.

[0011] In the utility model, the cross sections of the sliding groove and the sliding block are both T-shaped.

[0012] The limiting device of the utility model further includes a second swing rod, with both ends of the second swing rod rotatably arranged on the first limiting seat and the second limiting seat respectively.

[0013] In the utility model, the second limiting seat is clamped between the first swing rod and the second swing rod.

[0014] The first limit seat of the utility model includes a limit plate and a support plate, the edge of the limit plate is fixed to one side of the support plate, the first swing rod, the first telescopic rod and the second swing rod are all installed on the limit plate, and the support plate and the second limit seat are located on the same side of the limit plate.

[0015] The first limit seat of the utility model further comprises an anti-skid pad, and the anti-skid pad is installed on a side of the support plate away from the limit plate.

[0016] The limit plate of the utility model is provided with a first hinge seat and a second hinge seat, the end of the first swing rod is hinged on the first hinge seat and fits with the first hinge seat, the end of the second swing rod is hinged on the second hinge seat and fits with the second hinge seat, and the first swing rod and the second swing rod are located between the first hinge seat and the second hinge seat.

[0017] In the utility model, the first swing rod is parallel to the second swing rod.

[0018] The second limiting seat of the utility model is provided with a heat dissipation opening.

[0019] The beneficial effects of the utility model are:

[0020] The first limit seat, the second limit seat, the first swing rod and the first telescopic rod form a quadrilateral connecting rod structure. During the telescopic process, the first telescopic rod can change the distance between the second limit seat and the first limit seat. After the first telescopic rod stops telescoping, the distance between the first limit seat and the second limit seat can be well stabilized by utilizing the stability of the quadrilateral connecting rod structure.

[0021] The cabinet is provided with a mounting groove, and the limiting device and the refrigerator are both installed in the mounting groove, the first limiting seat abuts against the wall, and the second limiting seat abuts against the back of the refrigerator. When the cabinet door of the refrigerator is pushed, the first limiting seat presses against the wall, and at the same time, due to the first swing rod and the first telescopic rod limiting the distance between the first limiting seat and the second limiting seat, the refrigerator cannot approach the wall during the pressure process, so the cabinet door can be in the same vertical plane with the opening of the mounting groove when being pressed, so as to avoid being blocked by the edge of the opening of the mounting groove when the cabinet door is opened.

[0022] The telescopic design of the first telescopic rod allows the distance between the first limit seat and the second limit seat to be adjustable, thereby matching the installation of refrigerators of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment:

[0038] See Figure 1 and Figure 2 , this embodiment provides a limiting device, including a first limiting seat 1, a second limiting seat 2, a first swing rod 3 and a first telescopic rod 4. Among them, the first direction, the second direction and the third direction are perpendicular to each other in pairs, and the second direction is perpendicular to the horizontal plane.

[0039] The two ends of the first swing rod 3 are rotatably arranged on the first limit seat 1 and the second limit seat 2 respectively, and the rotation plane of the first swing rod 3 is perpendicular to the first direction. The first telescopic rod 4 is arranged along the third direction, one end of the first telescopic rod 4 is fixed on the first limit seat 1, and the other end of the first telescopic rod 4 is arranged on the second limit seat 2, and the second limit seat 2 can slide along the second direction at the end of the first telescopic rod 4. Thus, the first limit seat 1, the second limit seat 2, the first swing rod 3 and the first telescopic rod 4 form a quadrilateral connecting rod structure. During the telescopic process of the first telescopic rod 4, the second limit seat 2 will move along the second direction on the first limit seat 1, and the first swing rod 3 will also rotate on the first limit seat 1, and the relative rotation between the first swing rod 3 and the second limit seat 2 can change the distance between the second limit seat 2 and the first limit seat 1.

[0040] In this embodiment, the first telescopic rod 4 is an electric push rod, and the rotation of the first swing rod 3 is controlled by the telescopic movement of the first telescopic rod 4, so the rotation of the first swing rod 3 can match the telescopic movement of the first telescopic rod 4. After the first telescopic rod 4 stops telescoping, the stability of the quadrilateral connecting rod structure can be used to stabilize the distance between the first limit seat 1 and the second limit seat 2.

[0041] There are installation slots on the cabinet, see Figure 5 and Figure 6 , the limiting device and the refrigerator 200 are both installed in the installation groove, the limiting device is located between the wall 100 and the refrigerator 200, the refrigerator 200 is supported on the ground, and the cabinet door of the refrigerator 200 and the opening of the installation groove are in the same vertical plane. Among them, the first limiting seat 1 abuts against the wall 100, and the second limiting seat 2 abuts against the back of the refrigerator 200. When the cabinet door of the refrigerator 200 is pushed, the back of the refrigerator 200 presses the second limiting seat 2 along the third direction, and the pressure of the first swing rod 3 and the first telescopic rod 4 is transmitted, so that the first limiting seat 1 presses the wall 100 along the third direction. Due to the restriction of the first swing rod 3 and the first telescopic rod 4 on the distance between the first limiting seat 1 and the second limiting seat 2, the refrigerator 200 cannot approach the wall 100 during the pressure process, thereby enabling the cabinet door of the refrigerator 200 to always be in the same vertical plane with the opening of the installation groove during the pressure process, thereby avoiding the cabinet door being blocked by the edge of the installation groove opening when opening.

[0042] The first telescopic rod 4 can change the distance between the first limit seat 1 and the second limit seat 2 through telescopic action, thereby matching the installation of refrigerators 200 of different sizes on the cabinet, ensuring that the cabinet door of the refrigerator 200 and the opening of the installation groove are in the same vertical plane.

[0043] See also Figure 3 and Figure 4In this embodiment, a slide groove 21 is provided on the second limit seat 2, and the slide groove 21 extends along the second direction. A slider 41 is provided at the end of the first telescopic rod 4, and the slider 41 is slidably disposed in the slide groove 21. Preferably, the cross sections of the slide groove 21 and the slider 41 are both T-shaped to prevent the slider 41 from detaching from the slide groove 21.

[0044] In order to improve the stability of the second limiting seat 2 on the first limiting seat 1, the limiting device also includes a second swing rod 5, the two ends of which are rotatably arranged on the first limiting seat 1 and the second limiting seat 2, respectively, and the ends of the first swing rod 3 and the second swing rod 5 can cooperate to support the second limiting seat 2. The working principle of the second swing rod 5 is the same as that of the first swing rod 3, and will not be repeated in this embodiment.

[0045] Preferably, the second limiting seat 2 is clamped between the first swing rod 3 and the second swing rod 5 , and the first swing rod 3 is parallel to the second swing rod 5 .

[0046] The first limiting seat 1 of this embodiment includes a limiting plate 11, a supporting plate 12 and an anti-slip pad 13. The limiting plate 11 is perpendicular to the third direction, the supporting plate 12 is perpendicular to the second direction, the bottom edge of the limiting plate 11 is fixed to the upper surface of the supporting plate 12, and the bottom edge of the limiting plate 11 is also located at the edge of the supporting plate 12. The horizontally arranged supporting plate 12 can be stably supported on the ground, and the limiting plate 11 can fully fit with the wall 100. The second limiting seat 2 is in the shape of a flat plate, and the second limiting seat 2 is parallel to the limiting plate 11. The first swing rod 3, the first telescopic rod 4 and the second swing rod 5 are all installed on the limiting plate 11, and the supporting plate 12 and the second limiting seat 2 are located on the same side of the limiting plate 11, so the second limiting seat 2 can also fully fit with the back of the refrigerator 200.

[0047] The second limiting seat 2 is provided with a heat dissipation port 22 , and the heat on the back of the refrigerator 200 can be conducted to between the first limiting seat 1 and the second limiting seat 2 through the air at the heat dissipation port 22 , which helps the refrigerator 200 to dissipate heat.

[0048] The anti-skid pad 13 is installed on the side of the support plate 12 away from the limiting plate 11 to increase the friction between the first limiting seat 1 and the ground, prevent the first limiting seat 1 from sliding on the ground, and ensure that the limiting plate 11 can always fit the wall 100.

[0049] In this embodiment, a first hinge seat 111 and a second hinge seat 112 are provided on the limit plate 11. The first hinge seat 111, the second hinge seat 112 and the support plate 12 are located on the same side of the limit plate 11. The end of the first swing rod 3 is hinged to the first hinge seat 111 and is in contact with the first hinge seat 111. The end of the second swing rod 5 is hinged to the second hinge seat 112 and is in contact with the second hinge seat 112. The first swing rod 3 and the second swing rod 5 are located between the first hinge seat 111 and the second hinge seat 112.
