[0003] With the continuous development of modern technology, people's living standards are constantly improving, and their requirements for life and entertainment are also constantly increasing. In addition to audio, there are also demands for video playback, projection, and even VR, which has led to an increase in related equipment. Correspondingly, integrated audio cabinets for placing audio, projection and other equipment have emerged. For example, the Chinese utility model patents with announcement numbers CN215834228U and CN210930176U both disclose related integrated cabinets.

[0004] Due to the increase in the equipment carried, the above-mentioned integrated cabinet is difficult to be moved by manual movement, so rollers are usually installed on the bottom of the integrated cabinet, and in order to prevent the integrated cabinet from moving during use, the rollers are also equipped with a brake function.

[0005] However, when the integrated audio equipment cabinet disclosed in the prior art is applied to a ship, the contact area between the roller and the ship deck is small. Therefore, when the ship shakes, the roller is likely to slip on the ship deck, causing the integrated audio equipment cabinet to collide with the ship bulkhead or other equipment. Therefore, it is necessary to design a new integrated audio equipment cabinet that increases the stability of its support while maintaining its easy-to-move function. Utility Model Content

[0006] In view of the problem in the prior art that the rollers of the integrated audio equipment cabinet are prone to slippage, the purpose of the utility model is to provide an integrated audio equipment cabinet so as to at least partially solve the above problem.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood based on the overall idea of ​​the utility model and the specific context of the scheme.

[0025] like Figure 1-2 As shown, the embodiment of the utility model provides an integrated cabinet for audio equipment, including a cabinet body 1. The cabinet body 1 is a hollow rectangular body structure, and a partition is usually provided inside the cabinet body 1 to facilitate dividing the internal space of the cabinet body 1 into multiple parts, so as to place various equipment including audio equipment separately. In addition, rollers 2 are fixedly installed at the four corners of the bottom surface of the cabinet body 1.

[0026] In this embodiment, a movable foot support is also installed on the cabinet 1. When the integrated audio equipment cabinet needs to be moved, the movable foot support is away from the ground, so that the cabinet 1 can be moved through the rollers 2; when the integrated audio equipment cabinet needs to be used, the movable foot support lifts the cabinet 1 and leaves it off the ground (or deck), thereby replacing the rollers 2 to support the cabinet 1.

[0027] Specifically, the movable foot support includes a support 3, a foot pad 4, a return spring 5, a rotating shaft 6, a cam 7 and a force-adding rod 8, wherein:

[0028] The support 3 is in a rectangular plate or block shape, and is located at the center of the bottom surface of the cabinet 1, that is, the roller 2 is arranged in a surrounding shape on the outside of the support 3. The support 3 is slidably connected with the bottom surface of the cabinet 1 along the vertical direction. For example, a plurality of vertically arranged guide rods are welded on the bottom surface of the cabinet 1, and corresponding guide holes for matching are opened on the support 3, so that the support 3 moves vertically relative to the bottom surface of the cabinet 1 under the guidance of the guide rods;

[0029] The foot pad 4 is made of a material suitable for increasing friction, such as rubber, and is in a sheet-like structure, and is fixed to one side of the bottom surface of the support 3 by screws. There are multiple foot pads 4 and they are symmetrically distributed about the center of the bottom surface of the support 3. For example, four foot pads 4 are respectively fixed at the four corners of the bottom surface of the support 3;

[0030] The return spring 5 is configured as a tension spring, and its two ends are respectively connected to the top surface of the support 3 and the bottom surface of the cabinet 1. The return spring 5 is used to provide an elastic force to move the support 3 toward the bottom surface of the cabinet 1.

[0031] The rotating shaft 6 is arranged horizontally, and a bearing is installed on it, and a bearing seat is welded on one side of the bottom surface of the cabinet 1, so that the rotating shaft 6 can be rotatably connected to the cabinet 1. The rotating shaft 6 is located between the top surface of the support 3 and the bottom surface of the cabinet 1. The cam 7 is configured as a disc cam and is fixed to the rotating shaft 6 by a key. The profile of the cam 7 is egg-shaped, and the cam 7 is also located between the top surface of the support 3 and the bottom surface of the cabinet 1, that is, under the action of the reset spring 5, the profile of the cam 7 is always in contact with the top surface of the support 3. One end of the rotating shaft 6 extends from the bottom surface of the cabinet 1, and the force rod 8 is fixed to this end of the rotating shaft 6.

[0032] In this embodiment, the lift of the cam 7 is greater than the ground clearance of the foot pad 4. The ground clearance refers to the distance from the foot pad 4 to the ground or deck when the base circle profile of the cam 7 contacts the top surface of the support 3, that is, in the initial state, the base circle profile of the cam 7 contacts the top surface of the support 3.

[0033] In this way, when in use, after the rotating shaft 6 is driven to rotate by the force-adding rod 8, the support 3 can be pushed to move in the direction away from the bottom surface of the cabinet 1 with the help of the contour of the cam 7, until the support 3 moves to the farthest distance from the bottom surface of the cabinet 1 (the central axis of the cam 7), the cabinet 1 and the roller 2 installed on the bottom surface are supported and lifted off the ground or deck. At this time, the cabinet 1 is in contact with the ground or deck through the foot pad 4, so it is only necessary to increase the area of ​​the foot pad 4 to effectively increase the friction, thereby preventing the cabinet 1 from slipping relative to the ground or deck.

[0034] It is understandable that the cabinet 1 is also provided with a fixing buckle 9, which is used to fix the force-adding rod 8 when the support 3 moves to the farthest distance from the central axis of the cam 7. For example, in this embodiment, the fixing buckle 9 is configured as a lock buckle for easy operation, and the force-adding rod 8 is correspondingly provided with a hook or a hanging ear suitable for matching with the lock buckle. Of course, the fixing buckle 9 can also be replaced by a rope, a cable tie, etc., as long as the force-adding rod 8 can be fixed.

[0035] It is understandable that a limit block 10 is also provided on the cabinet 1, and the limit block 10 is used to limit the maximum rotation angle of the force rod 8, and when the force rod 8 rotates to the limit block 10, the support 3 moves to the farthest distance from the central axis of the cam 7. This arrangement prevents the force rod 8 from excessive rotation, thereby facilitating operation and use.

[0036] It is understandable that the cabinet 1 is also provided with an elastic slot 11 adapted to the force rod 8, and the elastic slot 11 is specifically configured as an arc-shaped structure made of elastic material, and its opening size is slightly smaller than the center of the force rod 8, and when the force rod 8 is embedded in the elastic slot 11, the support 3 is located at the closest point to the central axis of the cam 7. In this way, when the movable foot support is not in use, the force rod 8 can also be effectively disposed of to prevent it from accidentally deflecting due to bumps or shaking.

[0037] It is understandable that the force-adding rod 8 can also be a telescopic rod, such as a sleeve-type or threaded telescopic rod. Such a configuration enables the rotating shaft 6 to be driven to rotate with a small force, thereby facilitating use.

[0038] The use process of the integrated audio equipment cabinet disclosed in the utility model is as follows:

[0039] When the integrated audio equipment cabinet is used, it is equipped with audio equipment and other equipment. In order to prevent it from slipping, it is necessary to support the cabinet 1 with a movable foot support instead of the roller 2. During operation, first remove the force rod 8 from the elastic slot 11, then extend the force rod 8, and drive the rotating shaft 6 to rotate through the force rod 8. Then, the support 3 moves in the direction away from the bottom surface of the cabinet 1 under the thrust given by the profile of the cam 7, until the force rod 8 is blocked by the limit block 10, and then the force rod 8 is fixed by the fixing buckle 9. At this time, the support 3 moves to the farthest distance from the central axis of the cam 7, and because the lift of the cam 7 is greater than the ground clearance of the foot pad 4, the cabinet 1 and the roller 2 installed on the bottom surface are lifted up by the movable foot support and leave the ground or deck. At this time, the cabinet 1 is only in contact with the ground or deck through the foot pad 4, and because the contact area between the foot pad 4 and the ground or deck is larger than that of the roller 2, it can effectively increase the friction force, thereby preventing the cabinet 1 from slipping relative to the ground or deck.

[0040] When the integrated audio equipment cabinet needs to be moved, first release the lock of the fixing buckle 9 on the force rod 8, and then rotate the force rod 8 in the opposite direction until the force rod 8 is embedded in the elastic slot 11. At this time, under the action of the reset spring 5, the support 3 moves to the farthest distance from the central axis of the cam 7, that is, the cabinet body 1 contacts the ground or deck through the roller 2, and the transfer operation of the integrated audio equipment cabinet can be carried out.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
