Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to a limiting device and a cabinet. Background Technology

[0002] Currently, the connection between the cabinet body and the cabinet door is mainly achieved through hinges. This design allows the cabinet door to rotate relative to the cabinet body, thus enabling the door to open and close. However, many traditional hinge devices are not equipped with limit devices. Therefore, when the user's wall is uneven, the weight of the cabinet door may cause it to automatically open when closed or automatically close when open. This undoubtedly seriously affects the user experience and causes inconvenience in daily life. Utility Model Content

[0003] This utility model provides a limiting device and cabinet body to improve the problem of automatic rotation of the cabinet door when it is in the open or closed position.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A limiting device includes a base and a rotating component. The base is used to connect to a cabinet body, and the rotating component is used to connect to a cabinet door. The base and the rotating component are rotatably connected relative to each other. One of the base or the rotating component is provided with a movable latching member, and the other is provided with a latching position. The latching member or latching position rotates with the cabinet door. When the cabinet door is in the open position and the closed position, the latching member is latched into the latching position.

[0006] Furthermore, the base is provided with an installation cavity and a plug-in cavity arranged radially along the installation cavity, and the base is provided with a fixing plate for connecting a solid; the rotating component includes a rotating shaft and a connecting plate connected to the rotating shaft, and the connecting plate is used to connect a cabinet door.

[0007] Furthermore, the rotating shaft is rotatably disposed within the insertion cavity, the mounting cavity is provided with the snap-fit ​​member, the snap-fit ​​member is movable along the axial direction of the mounting cavity, and the outer side of the rotating shaft is provided with the snap-fit ​​position.

[0008] Furthermore, a first snap-fit ​​member is provided in the mounting cavity located on one side of the rotating shaft, and a second snap-fit ​​member is provided in the mounting cavity located on the other side of the rotating shaft. The outer surfaces of the rotating shaft opposite each other are respectively provided with a first snap-fit ​​position and a second snap-fit ​​position.

[0009] When the cabinet door is in the closed position, the first latching component latches into the first latching position, and the second latching component latches into the second latching position; when the cabinet door is in the open position, the first latching component latches into the second latching position, and the second latching component latches into the first latching position.

[0010] Furthermore, the mounting cavity is provided with a pressure cap and a spring. The pressure cap is threaded to the mounting cavity, and the two ends of the spring abut against the pressure cap and the snap-fit ​​component, respectively. The force exerted by the spring on the snap-fit ​​component can be adjusted by rotating the pressure cap.

[0011] Furthermore, the minimum radial dimension of the mounting cavity is smaller than the maximum radial dimension of the snap-fit ​​element.

[0012] Furthermore, the mounting cavity has a tapered hole with a radial dimension that gradually decreases towards the insertion cavity at one end near the insertion cavity, and the snap-fit ​​component is a ball bearing with a radial dimension greater than the minimum radial dimension of the tapered hole.

[0013] Furthermore, the locking position is an arc-shaped groove used to lock the rolling ball.

[0014] Furthermore, it also includes a sleeve, with the rotating shaft sequentially inserted into the sleeve and the insertion cavity, and the rotating shaft being rotatable relative to the sleeve.

[0015] A cabinet includes a cabinet body and a cabinet door, and also includes a limiting device as described above. The top and bottom of the cabinet door are respectively equipped with the rotating component, and the top plate and bottom plate of the cabinet body are respectively equipped with the base. Each of the rotating components is rotatably connected to the corresponding base.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model proposes a limiting device, including a base and a rotating component. The base is used to connect to the cabinet body, and the rotating component is used to connect to the cabinet door. The base and the rotating component are rotatably connected, and one of the base and the rotating component is provided with a movable latching component, while the other is provided with a latching position. In use, the latching component or latching position rotates with the cabinet door. When the cabinet door is in the open and closed positions, the latching component is engaged with the latching position, thereby limiting the rotation of the cabinet door in both the closed and open positions, improving the problem of automatic opening and closing of the cabinet door, and enhancing the user experience.

[0018] 2. The limiting device proposed in this utility model has a base with multiple snap-fit ​​parts and a rotating shaft with multiple snap-fit ​​positions. When the cabinet door is in the closed position and the open position, each snap-fit ​​part snaps into the corresponding snap-fit ​​position at the same time, ensuring that the limiting force formed between the multiple snap-fit ​​positions and snap-fit ​​parts is greater than the force of the cabinet door rotating automatically, thereby limiting the cabinet door to the open position and the closed position.

[0019] 3. The limiting device proposed in this utility model has a pressure cover and a spring in the installation cavity. By rotating the pressure cover, the force of the spring on the snap-fit ​​component can be adjusted to ensure that the spring still has sufficient force on the snap-fit ​​component after long-term use, so that the snap-fit ​​component can be snapped into the snap-fit ​​position.

[0020] 4. The limiting device proposed in this utility model has a minimum radial dimension of the mounting cavity that is smaller than the maximum radial dimension of the snap-fit ​​component, thereby preventing the snap-fit ​​component from falling out of the mounting cavity and causing the limiting device to fail.

[0021] 5. The limiting device proposed in this utility model has a ball as the locking component and an arc-shaped groove as the locking position, so that the ball can be disengaged from the locking position when the cabinet door is rotated.

[0022] 6. The cabinet door proposed in this utility model is equipped with the aforementioned limiting device. When the cabinet door is in the open or closed position, the limiting device restricts the rotation of the cabinet door, thereby reducing the problem of the cabinet door opening and closing automatically.

Detailed Implementation

[0032] Example 1

[0033] The following is combined with Figures 1 to 5 This embodiment will be described in detail.

[0034] This embodiment provides a limiting device, including a base 10 and a rotating component 20. The base 10 is used to connect to the cabinet body 30, and the rotating component 20 is used to connect to the cabinet door 40. The base 10 and the rotating component 20 are rotatably connected relative to each other. One of the base 10 or the rotating component 20 is provided with a movable latching member, and the other is provided with a latching position. The latching member or latching position rotates with the cabinet door 40. When the cabinet door 40 is in the open position and the closed position, the latching member is latched into the latching position, thereby limiting the rotation of the cabinet door 40 in both the closed and open positions, improving the problem of automatic opening and closing of the cabinet door 40, and improving the user experience. Since the base 10 and the rotating component 20 only need to maintain relative rotation, in other embodiments, the base 10 can be connected to the cabinet door 40, and the rotating component 20 can be connected to the cabinet body 30.

[0035] In this embodiment, as Figure 4 The base 10 has a mounting cavity 101 and a insertion cavity 102 arranged radially along the mounting cavity 101. The base 10 has a fixing piece 103 for connecting the cabinet body 30. The rotating component 20 includes a rotating shaft 201 and a connecting piece 202 connected to the rotating shaft 201. The connecting piece 202 is used to connect the cabinet door 40. The rotating shaft 201 is rotatably disposed in the insertion cavity 102. The mounting cavity 101 has a snap-fit ​​component that is movable along the axial direction of the mounting cavity 101. The outer side of the rotating shaft 201 has a snap-fit ​​position. When the cabinet door 40 is in the closed position and the open position, at least one snap-fit ​​component is snapped into one snap-fit ​​position. Furthermore, when the cabinet door 40 is in the closed position and the open position, each snap-fit ​​component is simultaneously snapped into the corresponding snap-fit ​​position, ensuring that the limiting force formed between the multiple snap-fit ​​positions and snap-fit ​​components is greater than the force of the cabinet door 40's automatic rotation, thereby restricting the cabinet door 40 to the open position and the closed position.

[0036] In this embodiment, as Figure 5As shown, a first latching member 501 is provided in the mounting cavity 101 on one side of the rotating shaft 201, and a second latching member 502 is provided in the mounting cavity 101 on the other side of the rotating shaft 201. The outer surfaces of the rotating shaft 201 opposite each other are provided with a first latching position 601 and a second latching position 602. When the cabinet door 40 is in the closed position, the first latching member 501 latches into the first latching position 601, and the second latching member 502 latches into the second latching position 602. When the cabinet door 40 is rotating, the first latching member 501 and the second latching member 502 abut against the outer surface of the rotating shaft 201. When the cabinet door 40 is in the open position, the first latching member 501 latches into the second latching position 602, and the second latching member 502 latches into the first latching position 601.

[0037] In other embodiments, the first latching position 601 and the second latching position 602 can be asymmetrically arranged. When the cabinet door 40 is in the closed position, the first latching member 501 latches into the first latching position 601, and the second latching member 502 disengages from the second latching position 602 and abuts against the outer surface of the pivot 201. When the cabinet door 40 is in the open position, the first latching member 501 disengages from the first latching position 601 and abuts against the outer surface of the pivot 201, and the second latching member 502 latches into the second latching position 602. In another embodiment, only a single latching member can be provided. When the cabinet door 40 is in the closed position, the latching member latches into the first latching position 601; when the cabinet door 40 is in the open position, the latching member latches into the second latching position 602.

[0038] In this embodiment, as Figure 4 As shown, the mounting cavity 101 is equipped with a pressure cap 70 and a spring 80. The pressure cap 70 is threaded into the mounting cavity 101, and the two ends of the spring 80 abut against the pressure cap 70 and the snap-fit ​​component, respectively. Since the spring 80 remains in a compressed state for a long time, its restoring force will gradually decrease. Therefore, by rotating the pressure cap 70, the force exerted by the spring 80 on the snap-fit ​​component is adjusted to ensure that the spring 80 still has sufficient force on the snap-fit ​​component after long-term use, ensuring that the snap-fit ​​component can be snapped into the snap-fit ​​position. An operating part is provided on the side of the pressure cap 70 away from the spring 80, which allows the user to rotate the pressure cap 70. Furthermore, the operating part is a groove 701, allowing the user to rotate the pressure cap 70 with a screwdriver or other similar tool.

[0039] In this embodiment, the minimum radial dimension of the mounting cavity 101 is smaller than the maximum radial dimension of the snap-fit ​​component to prevent the snap-fit ​​component from falling out of the mounting cavity 101 and causing the limiting function to fail. Furthermore, the mounting cavity 101 has a tapered hole with a radial dimension gradually decreasing towards the insertion cavity 102 at one end. The snap-fit ​​component is a ball bearing, and the radial dimension of the ball bearing is larger than the minimum radial dimension of the tapered hole. Specifically, the snap-fit ​​position is an arc-shaped groove 701 for snapping the ball bearing, and the arc-shaped groove 701 also facilitates the disengagement of the ball bearing from the snap-fit ​​position when the cabinet door 40 rotates.

[0040] In this embodiment, a sleeve 90 is also included. The rotating shaft 201 is sequentially inserted into the sleeve 90 and the insertion cavity 102, and the rotating shaft 201 is rotatable relative to the sleeve 90. The sleeve 90 is used to embed into the top plate and bottom plate of the cabinet body 30 to provide movement space for the rotating shaft 201 and reduce the friction between the rotating shaft 201 and the cabinet body 30.

[0041] The working principle of the limiting device proposed in this utility model is as follows:

[0042] When cabinet door 40 is in the closed position, such as Figure 1 As shown, under the elastic force of the spring 80, the first latching part 501 latches into the first latching part 601 and the second latching part 502 latches into the second latching part 602, so that the cabinet door 40 is kept in the closed position, reducing the automatic opening of the cabinet door 40 due to rotation.

[0043] When cabinet door 40 is rotating, such as Figure 2 As shown, the cabinet door 40 drives the rotating shaft 201 to rotate around its axis. The first latching member 501 disengages from the first latching position 601 and abuts against the outer side of the rotating shaft 201. The second latching member 502 disengages from the second latching position 602 and abuts against the outer side of the rotating shaft 201.

[0044] Continue rotating the cabinet door by 40 to bring it to the open position, as shown. Figure 3 As shown, under the elastic force of the spring 80, the first latching member 501 is pushed to latch onto the second latching position 602, and the second latching member 502 is latched onto the first latching position 601, so that the cabinet door 40 is kept in the open position, reducing the automatic closing of the cabinet door 40 due to rotation.

[0045] Example 2

[0046] The following is combined with Figure 6 and Figure 7 This embodiment will be described in detail.

[0047] This embodiment provides a cabinet, including a cabinet body 30 and a cabinet door 40, and also includes a limiting device as described above. Rotating components 20 are respectively installed on the top and bottom of the cabinet door 40. Bases 10 are respectively installed on the top plate and bottom plate of the cabinet body 30. Sleeves 90 are respectively installed through the top plate and bottom plate of the cabinet body 30. The rotating shaft 201 of each rotating component 20 is rotatably connected to the insertion cavity 102 of the corresponding base 10 after passing through the sleeve 90.

[0048] When cabinet door 40 is in the open or closed position, the rotation of cabinet door 40 is restricted by the limit device, which can reduce the problem of cabinet door 40 opening and closing automatically. Specifically, when cabinet door 40 is in the closed position, such as... Figure 7As shown, the first latching component 501 latches into the first latching position 601, and the second latching component 502 latches into the second latching position 602. The cabinet door 40 remains in the closed position and will not open automatically; when the cabinet door 40 is in the open position, as... Figure 6 As shown, when the cabinet door 40 rotates 180 degrees, the first latching piece 501 latches into the second latching position 602, and the second latching piece 502 latches into the first latching position 601, so that the cabinet door 40 remains in the open position and will not close automatically.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model.
