DETAILED DESCRIPTION

[0027] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1, refer to the specification Figure 1-5 , a fixing structure applied to a desktop base, comprising a base limiting structure for limiting and fixing a base connecting member, and a desktop fixing structure for fixing the base limiting structure on a desktop;

[0029] The base limiting structure includes a support plate 18, an outer cover 19 and a cushion 21, wherein the support plate 18 is provided with an auxiliary groove 20. In order to prevent the base connector from rotating, the auxiliary groove 20 generally adopts an angular shape, which can be a triangle or a waist shape for a simpler one, or a multi-sided shape for a more complex one. The base connector is limited by the insertion and the angular shape of the base connector.

[0030] After the base connector is inserted into the auxiliary groove 20, the outer cover 19 is buckled onto the support plate 18 and fixed to the support plate 18 by bolts. At this time, under the action of the outer cover 19, the support plate 18 and the auxiliary groove 20, the base connector cannot be displaced relative to the base limiting structure.

[0031] One side of the base limiting structure is detachably connected to the connecting assembly in the desktop fixing structure, wherein the connecting assembly includes a connecting block 11, a guide plate 12, and a threaded rod 2 rotating bearing block 13, and the support plate 18 is detachably connected to the connecting block 11 by bolts, and the connecting block 11 is also installed on the guide plate 12 by bolts, and a first positioning column is also provided on the connecting block 11, and the support plate 18 can be positioned and installed by the first positioning column;

[0032] The desktop fixing structure also includes a limit assembly, in which the middle guide plate 12 of the connecting assembly guides the limit assembly, a guide groove 15 is provided on the guide plate 12, and the sliding block 3 in the limit assembly is provided with a rotating shaft 8 inserted into the guide groove 15, and the rotating shaft 8 is also rotatably connected to the limit plate.

[0033] The limiting plate is divided into a limiting part 4 and a hinge part. The limiting part 4 and the base limiting structure fix the desktop. During the fixing process, the soft pad 21 fits tightly against the desktop, which can increase the friction between the desktop and the device, so that the base connector can bear a certain weight more stably.

[0034] The hinged part is further divided into a major arc circle 5 and a connecting plate 6. The rotating shaft 8 is coaxial with the major arc circle 5 and passes through the major arc circle 5. The connecting plate 6 is tangent to the major arc circle 5 and realizes the horizontal state of the limiting part 4 as the extreme position of the limiting part 4. A limiting groove 7 for accommodating the hinged part is also provided on the sliding block 3. The plane of the connecting plate 6 can contact and fit with the side wall of the limiting groove 7. When the plane of the connecting plate 6 contacts and fits with the side wall of the limiting groove 7, the hinged part is in a horizontal state. Under the action of the limiting groove 7 and the connecting plate 6, the hinged part cannot continue to rotate counterclockwise along the rotating shaft 8. Under the action of the major arc circle 5, the hinged part can rotate clockwise along the rotating shaft 8 to the extreme position in the vertical direction.

[0035] The limiting assembly also includes a threaded rod 2 and a sliding block 3. The sliding block 3 is located in the guide plate 12. At the same time, the rotating shaft 8 on the sliding block 3 is also inserted into the guide groove 15 on the guide plate 12. The sliding block 3 is limited under the action of the guide groove 15 and the rotating shaft 8. The threaded rod 2 passes through the connecting block 11, the sliding block 3 and the rotating bearing block 13 in sequence along the moving direction of the sliding block 3, wherein the force-bearing operating end of the threaded rod 2 is located on the base limiting structure, and the rotation auxiliary end of the threaded rod 2 is located on the outside of the rotating bearing block 13. The limiting pin 10 connected to the rotation auxiliary end of the threaded rod 2 can be removed to limit the position of the threaded rod 2.

[0036] The hinge is also provided with a clearance groove 16 for accommodating the threaded rod 2. When the hinge is located at the extreme position in the vertical direction, the threaded rod 2 is inserted into the clearance groove 16. At the same time, the hinge is also in contact with the arc-shaped spring piece 17 arranged in the guide plate 12. When the connecting component needs to pass through a narrow space, the hinge is swung upward to the extreme position. At this time, the side surface of the hinge is in contact with the outer edge surface of the arc-shaped spring piece 17. In the process of the connecting component moving downward, the narrow space compresses the arc-shaped spring piece 17 through the hinge. In the process of the deformation of the arc-shaped spring piece 17, the connecting component moves downward to a position where the narrow space does not compress the hinge. Under the elastic action of the arc-shaped spring piece 17, the hinge swings outward at a certain angle. The staff lifts the connecting component upward, so that the lower end of the desktop can apply a certain pressure to the hinge and swing it to a horizontal position.

[0037] The connecting block 11 is provided with a through hole 14 whose diameter is larger than that of the threaded rod 2. During the installation of the threaded rod 2, the threaded rod 2 can directly pass through the connecting block 11. The threaded rod 2 is threadedly connected to the sliding block 3. Under the action of the thread, the threaded rod 2 rotates to drive the sliding block 3 to move up and down, thereby realizing the up and down movement of the limiting part 4 to get closer to or away from the desktop.

[0038] An auxiliary hole 1 is provided on the outer cover 19 in the base limiting structure, and the force-bearing operating end of the threaded rod 2 is located in the auxiliary hole 1. Since the auxiliary hole 1 is located above the desktop, the operator can rotate the threaded rod 2 without extending his hand under the desktop during the installation process. At the same time, the threaded rod 2 drives the limiting part 4 to approach the desktop, so as to achieve the purpose of clamping and fixing the desktop.

[0039] The guide plate 12 is also provided with a blocking plate 22 located in front of the rotating bearing block 13. When the threaded rod 2 drives the sliding block 3 to move downward, the blocking plate 22 contacts the bottom surface of the limiting part 4 and drives the end of the limiting part 4 to rotate clockwise and be stored in the guide plate 12, which can make it easier for the device to be taken out from the gap between the desktop and the wall. In addition, an arc-shaped surface is also provided above the blocking plate 22. By squeezing the bottom surface of the limiting part 4 with the arc-shaped surface, the limiting part can be better stored in the guide plate.

[0040] When the utility model is used, the staff first assembles each component one by one. When it is necessary to install the utility model on the desktop, the staff moves the table body facing the wall to a certain space, and the staff manually rotates the threaded rod 2. Under the drive of the threaded rod 2, the sliding block 3 moves in the direction of the rotating bearing block 13, and under the action of the blocking plate 22, the limiting part 4 swings in the direction of the threaded rod 2 and makes the threaded rod 2 located in the yield groove 16 on the limiting part 4, wherein the surface of the limiting part 4 contacts and squeezes the arc-shaped spring piece 17, so that the arc-shaped spring piece 17 is deformed, and the staff holds the base limiting structure to move the connecting assembly downward so that the limiting part 4 is located under the desktop. When the limiting part 4 is located under the desktop, the staff rotates the threaded rod 2 in the opposite direction, and the threaded rod 2 drives the limiting part 4 to move upward through the sliding block 3 and disengage from the blocking plate 22. Under the elastic action of the arc-shaped spring piece 17, the limiting part 4 is driven to swing outward at a certain angle. At this angle, when the base limiting structure is pulled up, the limiting part 4 can be caused to swing in the horizontal direction.

[0041] When the limiting part 4 is located below the desktop, the staff rotates the force-bearing operating end of the threaded rod 2 located above the desktop, and the threaded rod 2 rotates relative to the guide plate 12. Under the action of the thread of the threaded rod 2 itself, the threaded rod 2 drives the sliding block 3 to approach the desktop. As the sliding block 3 gradually approaches the desktop, the desktop presses the end of the limiting part 4 and forces the limiting part 4 to rotate counterclockwise.

[0042] When the end of the limiting portion 4 is pressed to a horizontal state by the desktop, the limiting groove 7 blocks the limiting portion 4 through the connecting plate 6, so the device can be fixed on the desktop through the limiting portion 4 and the base limiting structure;

[0043] When the device needs to be taken out, the staff rotates the threaded rod 2 in the opposite direction, and the threaded rod 2 drives the sliding block 3 thereon to move downward to the extreme position. During the downward movement of the sliding block 3, the blocking plate 22 squeezes the limiting part 4, and the squeezing of the blocking plate 22 makes the limiting part 4 rotate clockwise to a vertical state, so that it can be better taken out from the gap between the table body and the wall.

[0044] The utility model adopts a force-bearing operating end of the threaded rod 2 arranged above the desktop so that the limit plate can be close to or away from the desktop, so that when the device is fixed on the desktop, the operator can operate the device without extending his hand to the desktop, which increases the convenience of fixing the desktop base.

[0045] The utility model adopts the giving groove 16 provided on the limiting plate and the arc-shaped elastic sheet arranged in the guide plate 12, so that when there is a small gap between the table body and the wall, the fixing structure can be placed without manually widening the gap.

[0046] The utility model adopts a blocking plate 22 arranged on the guide plate 12, so that when the utility model needs to be taken out or put in from the enclosed space formed by the inner side of the table body and the wall, the limiting plate can be directly stored in the guide plate 12 through the blocking plate 22, so that it can be taken out more simply and quickly.

[0047] The multiple components of the utility model are connected by a disassembly structure, so that the utility model can be better stored during transportation and will not occupy a large space.
