Description

Technical Field

[0001] This utility model belongs to the field of display technology, and relates to a support structure and a display. Background Technology

[0002] Currently, in blood purification equipment, the display is integrated into the top of the main unit or set on the top of the main unit, providing the blood purification equipment with the functions of displaying the treatment interface and interactive operation.

[0003] To facilitate convenient monitor maintenance, Chinese patent CN222399706U discloses a detachable monitor assembly. This assembly features two hooks at the bottom of the monitor's front cover and a raised locking strip at the bottom of the back cover for the hooks to engage. However, this mounting structure has the following problem: when the monitor's front cover is opened, the hooks connecting to the bottom of the back cover can easily disengage from the locking strip, causing the monitor to fall off and rendering the monitor unusable. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a support structure that can prevent the display screen from falling off.

[0005] A display with this support structure was also proposed.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] The support structure includes a support portion disposed on the back cover / front shell of the display and a connector disposed on the front shell / back cover of the display that cooperates with the support portion. An anti-detachment structure is provided between the support portion and the connector to prevent the connector from falling off. The connector slides along a first direction. When the connector slides along the first direction to a set position, the connector can rotate around a second direction.

[0008] In the above-mentioned support structure, the support part is provided with a guide groove extending in a first direction, and the connecting body is provided with a rotating part extending in a second direction, and the rotating part is slidably engaged with the guide groove.

[0009] In the above-mentioned support structure, the anti-detachment structure includes a blocking part located at the outer end of the guide groove. When the rotating part slides along the first direction to the blocking part, the rotating part can rotate around the second direction.

[0010] In the above-mentioned support structure, the guide groove is provided with a limiting rib, and one side of the limiting rib and / or one side of the rotating part is provided with a first guide surface that facilitates the rotating part to pass over the limiting rib from the outside to the inside, and the other side of the limiting rib and / or the other side of the rotating part is provided with a second guide surface that facilitates the rotating part to pass over the limiting rib from the inside to the outside.

[0011] Because of the limiting ribs, when disassembling the monitor, manual force is required to make the rotating part pass over the limiting ribs and begin to slide and engage with the guide groove, thus preventing the monitor front cover from automatically separating from the monitor back cover during disassembly.

[0012] In the aforementioned support structure, the angle between the first guide surface and the bottom surface of the guide groove is smaller than the angle between the second guide surface and the bottom surface of the guide groove. Because the angle between the first guide surface and the bottom surface of the guide groove is smaller, it is easier for the rotating part to pass over the limiting rib, thus enabling the rotating part to achieve sliding self-locking with the guide groove when the monitor is installed and fastened. However, because the angle between the first guide surface and the bottom surface of the guide groove is larger, it is not conducive to the rotating part passing over the limiting rib. When disassembling the monitor, manual force is required to make the rotating part pass over the limiting rib.

[0013] In the aforementioned support structure, a recessed groove is provided on the lower side of the outer end of the guide groove. The recessed groove facilitates the rotation of the rotating part when it moves to the outer end of the guide groove along with the display housing; at the same time, it can limit the rotation of the rotating part to a certain extent, preventing the rotating part from sliding when the display housing is in a flipped state; when the rotating part slides into the recessed groove, the sinking feedback of the rotating part indicates that the display housing can be flipped.

[0014] In the aforementioned support structure, the bottom surface of the recessed groove smoothly transitions to the lower side surface of the guide groove. This design facilitates the flipping of the display casing back to an upright position and also makes it easier for the rotating part to slide from the recessed groove to the guide groove.

[0015] In the above-mentioned support structure, the rotating part is a cylinder / elliptical cylinder.

[0016] In the above-mentioned support structure, guide grooves are provided on two opposite sides of the support part, and there are two connecting bodies located on the two opposite sides of the support part where the guide grooves are provided. The rotating part provided on the connecting body and the corresponding guide groove are in sliding fit.

[0017] In the above-mentioned support structure, there are 1 to 3 support parts.

[0018] In the above-mentioned support structure, the display back cover / display front shell is provided with a sleeve extending along a first direction, and the display front shell / display back cover is provided with a limiting post that slides / clearly engages with the sleeve along the first direction. When the rotating part is located at the inner end of the guide groove, the limiting post slides with the sleeve, and when the rotating part is located at the outer end of the guide groove, the limiting post disengages from the sleeve.

[0019] The limiting posts and sleeves, along with the guide grooves, rotating parts, and limiting ribs, work together to prevent interference between the bottom of the monitor faceplate and the components inside the monitor cavity when the monitor faceplate is flipped off from the monitor back cover. In other words, the bottom of the monitor faceplate is moved outwards a certain distance before being flipped, ensuring that the bottom of the monitor faceplate does not compress the components inside the monitor cavity.

[0020] In the aforementioned support structure, the limiting column is a cross-shaped rib.

[0021] The aforementioned support structure also includes a pull cord, one end of which is connected to the back cover of the display, and the other end of which is connected to the front panel of the display. The display includes a back cover and a front panel, and also includes the aforementioned support structure.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The monitor front cover and monitor back cover are installed and fitted using a rotating part and guide groove. When opening and maintaining them, the monitor front cover and monitor back cover are not easy to suddenly separate and fall off, thus protecting the internal connecting wires from being broken. The limiting post and sleeve ensure that the bottom of the monitor front cover moves outward a certain distance before it can be flipped, avoiding the problem of the monitor front cover being flipped open too early and scratching other parts at the bottom of the monitor front cover. The pull rope acts as a safety rope to prevent the monitor front cover and monitor back cover from separating too quickly and causing damage. Attached Figure Description

Detailed Implementation

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] Example 1

[0036] The display shown in Figures 1-3 includes a display back cover 1, a display front cover 2, and a support structure disposed between the display back cover 1 and the display front cover 2.

[0037] The first direction is the front-to-back direction of the display, and the second direction is the left-to-right direction of the display. As shown in Figure 4, the support structure includes two support parts 10 located at the bottom inside the back cover 1 of the display and four connecting bodies 11 located at the bottom inside the front cover 2 of the display. Each support part 10 has a connecting body 11 on its left and right sides. Each support part 10 has a guide groove 3 extending in the front-to-back direction on its left and right sides. The width of the guide groove 3 extends in the vertical direction. Two guide grooves 3 located on the same support part 10 are arranged back to back. A rotating part 4 is provided on the connecting body 11 and extends into the corresponding guide groove 3. The rotating part 4 slides with the guide groove 3. A blocking part 5 is provided at the outer end of the guide groove 3 (i.e., the end near the front cover 2 of the display). The blocking part 5 is used to prevent the rotating part 4 from coming out of the guide groove 3.

[0038] To improve the structural strength of the connector 11, as shown in Figure 8, the connector 11 is made into a groove-shaped structure.

[0039] To ensure balance, the two support parts 10 are symmetrically arranged in the left-right direction.

[0040] As shown in Figures 5 and 6, each guide groove 3 is provided with a vertically extending limiting rib 6. The protrusion height of the limiting rib 6 in the left-right direction is greater than the distance from the rotating part 4 to the bottom surface of the guide groove 3. In order to facilitate the rotating part 4 to pass over the fiber rib, in addition to requiring the connecting body 11 to have a certain elasticity, as shown in Figures 5 and 6, a first guide surface 7 is provided on the side of the limiting rib 6 facing the display front cover 2 and the side of the rotating part 4 facing the display back cover 1. A second guide surface 8 is provided on the side of the limiting rib 6 facing the display back cover 1 and the side of the rotating part 4 facing the display front cover 2. As shown in Figure 9, the angle α between the first guide surface 7 and the bottom surface of the guide groove 3 is smaller than the angle β between the second guide surface 8 and the bottom surface of the guide groove 3.

[0041] Because the angle between the first guide surface 7 and the bottom surface of the guide groove 3 is small, it is easier for the rotating part 4 to pass over the limiting rib 6. This allows the rotating part 4 to slide and self-lock with the guide groove 3 when the monitor is installed and fastened. Because the angle between the first guide surface 7 and the bottom surface of the guide groove 3 is large, it is not easy for the rotating part 4 to pass over the limiting rib 6. When disassembling the monitor, manual force is required to make the rotating part 4 pass over the limiting rib 6, thus preventing the monitor front cover 2 from automatically separating from the monitor back cover 1 during disassembly.

[0042] As shown in Figure 7, the lower outer end of the guide groove 3 is provided with an arc-shaped recessed groove 9 with an enlarged opening. The bottom surface of the recessed groove 9 smoothly transitions with the lower surface of the guide groove 3. The recessed groove 9 facilitates the rotation of the rotating part 4 when it moves with the monitor housing 2 to the outer end of the guide groove 3, and at the same time, it can limit the rotation of the rotating part 4 to a certain extent, preventing the rotating part 4 from sliding when the monitor housing 2 is in a flipped state. When the rotating part 4 slides into the recessed groove 9, the downward feedback of the rotating part 4 indicates that the monitor housing 2 can be flipped, and it makes it easier for the rotating part 4 to slide from the recessed groove 9 to the guide groove 3.

[0043] As shown in Figure 8, the rotating part 4 is an elliptical cylinder, which can maintain a large contact area between the rotating part 4 and the guide groove 3 during the sliding engagement process, thereby improving connection stability and optimizing the force structure. At the same time, when the rotating part 4 enters the sink 9, it is easy for the display shell 2 to flip.

[0044] As shown in Figure 4, sleeves 12 extending in the front-to-back direction are provided at the four corners of the inner side of the monitor back cover 1, and limiting posts 13 that slide with the sleeves 12 are provided at the four corners of the monitor face shell 2. When the rotating part 4 is located at the inner end of the guide groove 3, the limiting posts 13 extend into the sleeves 12 to prevent interference between the bottom of the monitor face shell 2 and the components in the monitor cavity when the monitor face shell 2 is flipped off from the monitor back cover 1. When the rotating part 4 is located at the outer end of the guide groove 3, the limiting posts 13 have disengaged from the sleeves 12.

[0045] In this embodiment, as shown in Figure 4, the limiting column 13 is a cross-shaped rib.

[0046] To further facilitate the release of the limiting post 13 from the sleeve 12, as shown in Figure 4, the upper parts of the two sleeves 12 located on the upper part of the display housing 2 are formed with notches. When the display housing 2 slides outward a certain distance (10mm in this embodiment), the limiting post 13 can be released from the notch.

[0047] As shown in Figure 3, a pull cord 14 is provided between the monitor back cover 1 and the monitor front cover 2. One end of the pull cord 14 is connected to the upper end of the monitor back cover 1, and the other end is connected to the upper end of the monitor front cover 2. The pull cord 14 can be a single cord or multiple cords, which serve as a safety cord to prevent the monitor front cover 2 from being disassembled from the monitor back cover 1 too quickly and causing damage.

[0048] As shown in Figure 1, when the monitor front cover 2 is closed, the gap between the monitor front cover 2 and the monitor back cover 1 is relatively large because there are no screws or other structures to fix them at the bottom. The bottom gap is controlled by the cooperation of the rotating part 4 on the monitor front cover 2 and the limiting rib 6 on the monitor back cover 1. As shown in Figure 5, the monitor front cover 2 can be easily closed by the cooperation of the two first guide surfaces 7.

[0049] As shown in Figure 2, when the monitor cover 2 is slid open, the rotating part 4 of the monitor cover 2 can only slide within the guide groove 3 because the blocking part 5 at the outer end of the guide groove 3 restricts the rotating part 4 of the monitor cover 2 from leaving the guide groove 3.

[0050] As shown in Figure 3, when the monitor cover 2 is slid open by about 10mm, the rotating part 4 on the monitor cover 2 slides into the recess 9 of the monitor back cover 1. The sinking feedback of the monitor cover 2 indicates that the monitor cover 2 can be flipped.

[0052] The structural principle of this embodiment is basically the same as that of embodiment one. The difference is that the support part 10 is set on the display front shell 2, the guide groove 3 is set on the support part 10, the connector 11 is set on the display back cover 1, and the rotating part 4 is set on the connector 11.

[0053] Example 3

[0054] The structural principle of this embodiment is basically the same as that of embodiment one. The difference is that there is only one support part 10 and it is located in the middle of the lower inner side of the back cover 1 of the display. There are only two connectors 11 and they are located on the left and right sides of the support part 10 respectively. The pull rope 14 is located directly above the support part 10.
