Description

Technical Field

[0001] This utility model belongs to the field of laptop computer accessories technology, specifically a laptop computer stand. Background Technology

[0002] A laptop stand is a support tool used to place a laptop. It is usually adjustable and can adjust the height, angle, etc. according to the user's usage habits and needs. It can make the laptop placement more ergonomic, allowing the user to maintain a comfortable posture, and can also help improve the laptop's heat dissipation.

[0003] Laptops are small and lightweight, making them easy to carry. To accommodate this feature, most existing laptop stands are foldable. They use a rotating base, tray, and support plate to create a triangular support structure for holding the laptop. However, when cleaning the desktop or moving the laptop stand, the friction between the base and the desktop causes the stand to vibrate. This vibration can cause the support plate to pop out of its slot, the triangular support structure to break apart, and the laptop to fall onto the desktop.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a laptop stand. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a laptop stand that solves the problem in the prior art where, during operations such as cleaning the desktop that require dragging and moving the laptop stand, the friction between the base plate and the desktop causes the laptop stand to vibrate. In this case, the support plate is prone to jumping out of the positioning groove due to the vibration, causing the triangular support structure to collapse and the laptop to fall onto the desktop.

[0006] A laptop stand includes a base plate with a first rotating groove rotatably connected to a support plate. The support plate has a second rotating groove rotatably connected to a support plate. The base plate has several positioning grooves. Two of the support plates have rotating and sliding grooves. An adjusting plate is rotatably connected to the rotating groove and slidably connected to the sliding groove. The two adjusting plates are rotatably connected. A receiving block is fixedly connected to the base plate. A receiving groove is formed in the base plate and the receiving block. A threaded cylinder communicates with the receiving groove. A screw is threadedly connected to the threaded cylinder. A bullseye ball is fixedly connected to the screw and is located within the receiving groove.

[0007] Preferably, the base plate has a sliding groove, a slider is slidably connected to the sliding groove, a limit plate is fixedly connected to the slider, the limit plate has a limit groove, an elastic sheet is fixedly connected to the limit plate, and the elastic sheet is fixedly connected to the base plate.

[0008] Preferably, the slide groove is an L-shaped slider in cross-section.

[0009] Preferably, the tray has a placement groove, the depth of which is equal to the thickness of the support plate, and the end of the support plate away from the tray has a support protrusion. The tray also has a storage groove.

[0010] Preferably, the adjusting plate is a "Z" shaped plate, and cylinders are fixedly connected to both ends of the adjusting plate. The two cylinders are respectively located in the rotating groove and the sliding groove, and an anti-detachment plate is fixedly connected to the end of the cylinder away from the adjusting plate.

[0011] Preferably, the base plate is provided with a bending head, the bending head is provided with a first friction pad, and the support plate is provided with a second friction pad and a third friction pad.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model slightly lifts the end of the base plate away from the bullseye ball bearing. At this time, the base plate is connected to the desktop by rolling through the bullseye ball bearing, greatly reducing friction. The laptop stand can be easily dragged and moved on the desktop. At the same time, due to the reduced friction, the vibration amplitude is also greatly reduced, which can prevent the support plate from jumping out of the positioning groove due to vibration, thus ensuring the stability of the laptop stand during the movement.

[0014] 2. In this utility model, the screw is connected to the threaded cylinder. When the screw is rotated, the distance of the bullseye ball extending out of the receiving groove can be adjusted, thereby causing the base plate to tilt to different degrees, thus realizing the fine adjustment of the tilt angle of the laptop.

[0015] 3. In this utility model, the positioning groove and the limiting groove are initially misaligned. When the support plate needs to be inserted into the positioning groove, the support plate is first inserted into the limiting groove and abuts against the upper surface of the base plate. Then, the support plate is rotated, and the support plate drives the limiting plate to move through the limiting groove until the positioning groove and the limiting groove are connected. During this period, the elastic sheet deforms and stores force, inserting the support plate into the positioning groove. The elastic sheet wants to return to its original shape and applies external force to the limiting plate. At this time, the inclined surface of the limiting groove has a squeezing and limiting effect on the support plate, which can prevent the support plate from jumping out of the positioning groove due to vibration, further improving the stability of the laptop stand.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1

[0024] As attached Figure 1 To be continued Figure 4 As shown, this embodiment provides a laptop stand, including a base plate 1. The base plate 1 has a first rotating groove 2, and a support plate 3 is rotatably connected to the first rotating groove 2. The support plate 3 has a second rotating groove 4, and a support plate 5 is rotatably connected to the second rotating groove 4. The base plate 1 has several positioning grooves 6. By rotating the support plate 3 and the support plate 5 and inserting the support plate 5 into different positioning grooves 6, the base plate 1, the support plate 3, and the support plate 5 can be assembled into triangular support structures at different angles. Then, the laptop is placed on the support plate 3 to support the laptop. Two support plates 3 have rotating grooves 7 and sliding grooves 8. The rotating grooves 7 are rotatably connected to an adjustment plate 9, and the adjustment plate 9 is slidably connected to the sliding grooves 8. The adjusting plate 9 is rotatably connected, which moves the two support plates 3 closer to each other or further away. At this time, the included angle between the two adjusting plates 9 changes, and the position of the cylinder in the sliding groove 8 changes, so that the two adjusting plates 9 can move synchronously. The base plate 1 is fixedly connected to the receiving block 10. The base plate 1 and the receiving block 10 are provided with a receiving groove 11. The receiving groove 11 is connected to the threaded cylinder 12. The threaded cylinder 12 is threadedly connected to the screw 13. The screw 13 is fixedly connected to the bullseye ball 14. By rotating the screw 13, the distance of the bullseye ball 14 extending out of the receiving groove 11 can be adjusted. The bullseye ball 14 is located in the receiving groove 11 and contacts the table. This can reduce the friction between the base plate 1 and the table and reduce the vibration when dragging the base plate 1.

[0025] As can be seen from the above, by adjusting the angles of the tray 3 and the support plate 5, a triangular support structure is formed by the base plate 1, the tray 3, and the support plate 5. By inserting the support plate 5 into different positioning slots 6, the angle of the triangular support structure can be changed, thereby providing different angles of support for the laptop. According to the size of the laptop, the distance between the two trays 3 is adjusted. At this time, the included angle of the two adjustment plates 9 changes, and the position of the cylinder in the sliding groove 8 changes, ensuring that the two adjustment plates 9 move synchronously. After the tilt angle and distance of the laptop stand are adjusted, the laptop is placed on the tray 3 to provide support for the laptop.

[0026] When the laptop stand needs to be moved, slightly lift the end of the base plate 1 away from the bullseye ball 14. At this time, the base plate 1 is connected to the desktop by rolling through the bullseye ball 14, greatly reducing friction. The laptop stand can be easily dragged and moved on the desktop. At the same time, due to the reduced friction, the vibration amplitude is also greatly reduced, which can prevent the support plate 5 from jumping out of the positioning groove 6 due to vibration, thus ensuring the stability of the laptop stand during the movement.

[0027] Example 2

[0028] As attached Figure 1 To be continued Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the base plate 1 is provided with a sliding groove 15, the sliding groove 15 is slidably connected to a slider 16, the slider 16 is fixedly connected to a limiting plate 17, the limiting plate 17 slides on the base plate 1 through the cooperation of the slider 16 and the sliding groove 15, the limiting plate 17 is provided with a limiting groove 18, the positioning groove 6 and the limiting groove 18 are initially misaligned with each other, the limiting plate 17 is fixedly connected to an elastic piece 19, the elastic piece 19 accumulates energy through deformation as power, and the elastic piece 19 is fixedly connected to the base plate 1.

[0029] Specifically, the slide groove 15 has an "L" shaped cross-section for the slider 16, which prevents the slider 16 from separating from the slide groove 15.

[0030] Furthermore, the tray 3 has a placement groove 20, the depth of which is equal to the thickness of the support plate 5. The end of the support plate 5 away from the tray 3 has a support protrusion 21. The tray 3 has a storage groove 22, and the support plate 5 can be rotated into the placement groove 20. At this time, the support protrusion 21 is located in the storage groove 22, which is convenient for storage.

[0031] Furthermore, the adjusting plate 9 is a "Z" shaped plate, and cylinders are fixedly connected to both ends of the adjusting plate 9. The two cylinders are located in the rotating groove 7 and the sliding groove 8 respectively. An anti-detachment plate is fixedly connected to the end of the cylinder away from the adjusting plate 9. The anti-detachment plate is circular. The anti-detachment plate is set to prevent the adjusting plate 9 from separating from the rotating groove 7 and the sliding groove 8.

[0032] Furthermore, the base plate 1 is provided with a bending head 23, which supports the laptop and prevents the laptop from slipping when placed at an angle. At the same time, the design of the bending head 23 makes it easy to lift the base plate 1. The bending head 23 is provided with a first friction pad 24, and the support plate 3 is provided with a second friction pad 25 and a third friction pad 26. The first friction pad 24, the second friction pad 25 and the third friction pad 26 increase the friction between the bending head 23, the support plate 3 and the laptop, further preventing the laptop from slipping.

[0033] As can be seen from the above, when the support plate 5 needs to be inserted into the positioning groove 6, the support plate 5 is first inserted into the limiting groove 18 and abuts against the upper surface of the base plate 1. Then the support plate 5 is rotated, and the tilt angle of the support plate 3 changes. The support plate 5 drives the limiting plate 17 to move through the limiting groove 18 until the positioning groove 6 and the limiting groove 18 are connected. During this period, the elastic piece 19 deforms and stores force, inserting the support plate 5 downward into the positioning groove 6. The elastic piece 19 wants to return to its original shape and then applies external force to the limiting plate 17. At this time, the inclined surface of the limiting groove 18 has a squeezing and limiting effect on the support plate 5, which can prevent the support plate 5 from jumping out of the positioning groove 6 due to vibration, further improving the stability of the laptop stand. Since the number of positioning grooves 6 is limited and the position is fixed, the tilt angle of the support plate 5 inserted into different positioning grooves 6 can be calculated. The tilt angle of the inclined surface of the limiting groove 18 is set according to this tilt angle so that the inclined surface of the limiting groove 18 fits the support plate 5 as closely as possible, improving the limiting effect.
