Description

Technical Field

[0001] This utility model belongs to the field of television cart technology, and more specifically, it relates to a single-column mobile television cart. Background Technology

[0002] With the increasing demand for smart homes and efficient space utilization, the traditional method of placing a TV in one location and keeping it stationary is gradually being phased out. Portable TV stands are gradually replacing traditional wall-mounted or base-mounted installations, becoming an important option for flexible viewing.

[0003] Existing single-column trolleys generally adopt a fixed bottom frame structure, such as the frame being directly welded or bolted to the bottom of the column. Although this makes them easy to move, they cannot be folded for storage. The bolted fixing method is also more troublesome to disassemble, resulting in them still occupying a lot of space when not in use. This makes them unsuitable for scenarios that require frequent storage, and they also take up a lot of space during transportation. Utility Model Content

[0004] To address the problem that fixed-base frame structures cannot be folded for storage and occupy a large amount of space during transportation, this utility model proposes a single-column mobile TV trolley to overcome the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a single-column mobile TV trolley, including a column. A first displacement component and a second displacement component are respectively arranged inside the column. A rotating plate is provided on the outer surface of the first displacement component, and universal wheels are fixedly installed on the outer surface of the rotating plate. A limiting component is provided between the rotating plate and the first displacement component. A connecting component is provided on the outer surface of the second displacement component. The first displacement component is used to drive the rotating plate to slide inside the column, the limiting component is used to limit and fix the rotating plate, and the second displacement component is used to drive the connecting component to move. The connecting component is used to connect the TV.

[0007] Furthermore, the first displacement component includes a first screw, which is rotatably connected to the inside of the column. A base is threadedly connected to the outer surface of the first screw, and a square plate is fixedly connected to the outer surface of the base. A square groove is formed inside the column, and the square plate is slidably connected inside the square groove.

[0008] Furthermore, the limiting component includes a limiting plate, which is slidably connected to the inside of the rotating plate. A spring is fixedly connected to the outer surface of the limiting plate, and one end of the spring is fixedly connected to the inside of the rotating plate. The outer surface of the base is provided with a first limiting groove and a second limiting groove, and the limiting plate is used to insert into the first limiting groove and the second limiting groove.

[0009] Furthermore, the second displacement component includes a second screw, which is rotatably connected to the column. The outer surface of the second screw is threaded with a first sliding seat and a second sliding seat, respectively. The outer surface of the column is provided with a sliding groove, and the first sliding seat and the second sliding seat are slidably connected to the sliding groove.

[0010] Furthermore, the connecting assembly includes inclined plates, and there are multiple sets of inclined plates. The multiple sets of inclined plates are respectively fixedly installed on the outer surfaces of the first sliding seat and the second sliding seat. Vertical plates are fixedly connected to the outer surfaces of the multiple sets of inclined plates, and horizontal plates are fixedly installed on the outer surfaces of the vertical plates. Multiple sets of circular holes are opened on the outer surfaces of the vertical plates and the horizontal plates.

[0011] Furthermore, screws are threadedly connected between the vertical plate and the horizontal plate.

[0012] Furthermore, handwheels are fixedly connected to the outer surfaces of both the first screw and the second screw.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects the first displacement component and the rotating plate. The rotating plate is rotatably connected to the outer surface of the first displacement component. Before transportation, the rotating plate is rotated to be parallel to the column. At this time, the cross-section of the multiple rotating plates is smaller than the cross-section of the column. The first displacement component drives the multiple rotating plates to move upward, so that the multiple rotating plates and casters are retracted into the column, reducing the space occupied and facilitating transportation and storage.

[0015] 2. This utility model, through the connection of a limiting plate, a first limiting groove, and a second limiting groove, allows the rotating plate to be fixed in place when it is in a vertical state. This prevents unnecessary swinging of the rotating plate after it is retracted into the column. When the rotating plate is in a horizontal state, the limiting plate is fixed in place by inserting into the first limiting groove. At this time, the rotation of the rotating plate is blocked by the limiting plate, allowing the rotating plate to provide more stable support to the column.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-7 As shown, this utility model is a single-column mobile TV trolley, including a column 1. A first displacement component 2 and a second displacement component 6 are respectively arranged inside the column 1. A rotating plate 3 is arranged on the outer surface of the first displacement component 2. A universal wheel 4 is fixedly installed on the outer surface of the rotating plate 3. A limiting component 5 is arranged between the rotating plate 3 and the first displacement component 2. A connecting component 7 is arranged on the outer surface of the second displacement component 6. The first displacement component 2 is used to drive the rotating plate 3 to slide inside the column 1. The limiting component 5 is used to limit and fix the rotating plate 3. The second displacement component 6 is used to drive the connecting component 7 to move. The connecting component 7 is used to connect the TV.

[0030] The first displacement component 2 is driven to move inside the column 1, causing the first displacement component 2 to drive the rotating plate 3 and the caster wheel 4 to slide out of the column 1. This pushes the limiting component 5 to move, releasing the limiting fixation between the rotating plate 3 and the first displacement component 2. At this time, the rotating plate 3 can be pushed to rotate and unfold to support the column 1. Then, the TV is installed on the connecting component 7 on the outer surface of the column 1. The movement of the second displacement component 6 can drive the connecting component 7 and the TV to move, thereby adjusting the height of the TV.

[0031] This utility model connects the first displacement component 2 and the rotating plate 3. The rotating plate 3 is rotatably connected to the outer surface of the first displacement component 2. Before transportation, the rotating plate 3 is rotated to be parallel to the column 1. At this time, the cross-section of the multiple rotating plates 3 is smaller than the cross-section of the column 1. The first displacement component 2 drives the multiple rotating plates 3 to move upward, so that the multiple rotating plates 3 and the casters 4 are retracted into the column 1, reducing the space occupied and facilitating transportation and storage.

[0032] In one embodiment, the first displacement component 2 includes a first screw 201, which is rotatably connected to the inside of the column 1. A base 202 is threadedly connected to the outer surface of the first screw 201, and a square plate 203 is fixedly connected to the outer surface of the base 202. A square groove 204 is provided inside the column 1, and the square plate 203 is slidably connected to the inside of the square groove 204.

[0033] When the first screw 201 is rotated, the rotational tendency of the base 202 on the first screw 201 is blocked by the square plate 203 and the square groove 204. At this time, the first screw 201 can drive the base 202 to slide the square plate 203 along the square groove 204. The square groove 204 can limit the movement distance of the square plate 203 and the base 202 to prevent the base 202 from separating from the first screw 201. The base 202 can drive the rotating plate 3 to move out to the outside of the column 1 or retract the rotating plate 3 into the column 1.

[0034] In one embodiment, the limiting component 5 includes a limiting plate 501, which is slidably connected to the inside of the rotating plate 3. A spring 502 is fixedly connected to the outer surface of the limiting plate 501, and one end of the spring 502 is fixedly connected to the inside of the rotating plate 3. A first limiting groove 503 and a second limiting groove 504 are respectively opened on the outer surface of the base 202. The limiting plate 501 is used to insert into the first limiting groove 503 and the second limiting groove 504.

[0035] After the base 202 moves the rotating plate 3 to the outside of the column 1, it pushes the limiting plate 501 to slide inside the rotating plate 3. The limiting plate 501 compresses the spring 502 and separates from the second limiting groove 504 on the base 202. At this time, the rotating plate 3 can be pushed to rotate. After the rotating plate 3 rotates to the horizontal, the limiting plate 501 is released. The spring 502 pushes the limiting plate 501 to reset so that it is inserted into the first limiting groove 503 to limit and fix the rotating plate 3. At this time, the rotating plate 3 and the universal wheel 4 can support the column 1. When it is necessary to retract the rotating plate 3, the limiting plate 501 is pushed to move again so that it separates from the first limiting groove 503. The rotating plate 3 is rotated to the vertical and the limiting plate 501 is released. The base 202 can drive the rotating plate 3 and the universal wheel 4 to retract into the column 1.

[0036] In one embodiment, the second displacement component 6 includes a second screw 601, which is rotatably connected to the column 1. The outer surface of the second screw 601 is threaded with a first sliding seat 602 and a second sliding seat 603, respectively. The outer surface of the column 1 is provided with a sliding groove 604, and the first sliding seat 602 and the second sliding seat 603 are slidably connected to the sliding groove 604.

[0037] When the second screw 601 is rotated, the rotational tendency of the first sliding seat 602 and the second sliding seat 603 on the second screw 601 is blocked by the slide groove 604. At this time, the second screw 601 can drive the first sliding seat 602 and the second sliding seat 603 to slide up and down along the slide groove 604 at the same time.

[0038] In one embodiment, the connecting component 7 includes inclined plates 701, and there are multiple sets of inclined plates 701. The multiple sets of inclined plates 701 are respectively fixedly installed on the outer surfaces of the first sliding seat 602 and the second sliding seat 603. Vertical plates 702 are fixedly connected to the outer surfaces of the multiple sets of inclined plates 701. Horizontal plates 703 are fixedly installed on the outer surfaces of the vertical plates 702. Multiple sets of circular holes 704 are formed on the outer surfaces of both the vertical plates 702 and the horizontal plates 703.

[0039] In one embodiment, for the vertical plate 702, a screw 8 is threadedly connected between the vertical plate 702 and the horizontal plate 703.

[0040] Screw 8 is installed in the round hole 704 on the vertical plate 702 and the horizontal plate 703 to connect and fix the vertical plate 702 and the horizontal plate 703. When the first sliding seat 602 and the second sliding seat 603 move, they can drive the vertical plate 702 and the horizontal plate 703 to move synchronously and install the TV on the horizontal plate 703. The height of the TV can be adjusted by rotating the second screw 601.

[0041] In one embodiment, for the first screw 201, a handwheel 9 is fixedly connected to the outer surface of both the first screw 201 and the second screw 601.

[0042] After the user holds the handwheel 9, pushing different handwheels 9 can drive the first screw 201 and the second screw 601 to rotate respectively. The design of the handwheel 9 makes it easy for the user to use and avoids slippage when rotating the first screw 201 or the second screw 601.

[0043] Through the above technical solution, 1. By connecting the first displacement component 2 and the rotating plate 3, the rotating plate 3 is rotatably connected to the outer surface of the first displacement component 2. Before transportation, the rotating plate 3 is rotated to be parallel to the column 1. At this time, the cross-section of the multiple rotating plates 3 is smaller than the cross-section of the column 1. The first displacement component 2 drives the multiple rotating plates 3 to move upward, so that the multiple rotating plates 3 and the casters 4 are retracted into the column 1, reducing the space occupied and facilitating transportation and storage; 2. By connecting the limiting plate 501, the first limiting groove 503 and the second limiting groove 504, when the rotating plate 3 is in a vertical state, the limiting plate 501 and the second limiting groove 504 are inserted to limit and fix the rotating plate 3, avoiding unnecessary swinging after the rotating plate 3 is retracted into the column 1. When the rotating plate 3 is in a horizontal state, the limiting plate 501 and the first limiting groove 503 are inserted to limit and fix the rotating plate 3. At this time, the rotation of the rotating plate 3 is blocked by the limiting plate 501, so that the rotating plate 3 can provide more stable support for the column 1.
