[0002] Stage lights generally consist of a lamp body frame and a lamp head. The lamp head is pivotally connected to the lamp body frame, which contains a drive mechanism for rotating the lamp head. Stage lights are quite heavy, and when moving them, the base at the bottom of the lamp body frame is usually lifted. However, hands can easily slip off the base, causing the stage light to fall and be damaged. Utility Model Content

[0003] The purpose of this utility model is to provide a foldable handle structure that can be lifted up and down. The unlocking and locking operation of the handle is simple, ensuring that the handle will not rotate or shake during the lifting process, thus ensuring the safety and convenience of the handle during use. It can also be stored away to reduce space occupation.

[0004] To achieve the above objectives, this utility model provides a foldable handle structure that can be lifted up and down, including a handle, a lamp body bracket, a movable plate, a fixed plate, an elastic element, a sliding block, and a limiting slider. The fixed plate is installed inside the lamp body bracket and has a limiting block. The movable plate has a guide groove that slides with the limiting block. One end of the elastic element is connected to the fixed plate, and the other end is connected to the movable plate. The sliding block is connected to the movable plate. The lamp body bracket has a sliding groove. The limiting slider includes a sliding block, a sliding prism, and a sliding cylinder. The sliding block is slidably disposed in the sliding groove and has a sliding inclined groove. The sliding block has a sliding rod that passes through the sliding groove. A sliding groove is formed and slides in engagement with the sliding groove. The sliding prism is connected between the sliding cylinder and the sliding block. The handle is provided with a limiting hole that matches the shape of the sliding prism. When the movable plate is pressed down, the elastic element is compressed, the sliding rod moves downward and moves to the lower part of the sliding groove, simultaneously driving the limiting slider to move, so that the sliding prism retracts into the sliding groove. The limiting hole of the handle can rotate in engagement with the sliding cylinder. When the movable plate loses external force, under the restoring force of the elastic element, the movable plate moves upward, and the sliding rod moves upward and moves to the upper part of the sliding groove, simultaneously driving the limiting slider to move, so that the sliding prism is inserted into the limiting hole of the handle.

[0005] As a preferred embodiment of this utility model, a button is provided on the top of the movable plate.

[0006] As a preferred embodiment of this utility model, the button is provided with a first magnet, and the handle is provided with a second magnet that is magnetically attracted to the first magnet.

[0007] As a preferred embodiment of this utility model, the lamp body bracket is provided with a limiting pressure plate, the limiting pressure plate covers the sliding groove and surrounds the sliding groove to form a sliding cavity, and the limiting pressure plate is provided with a limiting groove that cooperates with the moving rod.

[0008] As a preferred embodiment of this utility model, the upper side wall of the lamp body bracket is provided with a handle storage groove that matches the shape of the handle.

[0009] As a preferred embodiment of this utility model, the cross-section of the sliding prism is square, and the diameter of the sliding cylinder is the same as the side length of the sliding prism.

[0010] In a preferred embodiment of this invention, the sliding cylinder and the sliding prism are rotatably connected.

[0011] As a preferred embodiment of this utility model, the limiting block includes a screw and a self-locking nut, the fixing plate is provided with a connecting hole, the screw passes through the connecting hole and the guide groove and is threadedly connected to the self-locking nut.

[0012] As a preferred embodiment of this utility model, the elastic element is a tension spring, the upper part of the fixed plate is provided with a first connecting hook connected to the tension spring, and the lower part of the movable plate is provided with a second connecting hook connected to the tension spring.

[0013] Compared with the prior art, the foldable handle structure that can be lifted up and down according to this utility model embodiment has the following advantages:

[0014] This invention utilizes a pressing movable plate, which overcomes the elastic force of the elastic element. The sliding rod on the sliding block drives the limiting slider to retract, causing the sliding cylinder on the limiting slider to engage with the limiting hole on the handle. The handle is no longer restricted by the sliding prism, thus unlocking it. The handle can rotate to lower or retract. When the stage light is not being moved, the handle can be stored away, reducing space occupation and preventing damage from collisions caused by the protruding handle during transportation or use. After the movable plate is released, the elastic element loses the resistance of external force. Under the restoring force of the elastic element, the elastic element drives the movable plate and the sliding rod to move upward synchronously. During the upward movement of the sliding rod, the limiting slider extends outward, so that the sliding prism of the limiting slider is inserted into the limiting hole on the handle. At this time, the handle cannot rotate under the limiting action of the sliding prism, thus locking the handle. This allows the handle to be stably kept in the lifting or retracted state, ensuring that the handle will not rotate or shake randomly during the lifting process. This makes it convenient to lift the stage light by the handle, ensuring the safety and convenience of the handle during use. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 this utility model.

[0025] like Figures 1 to 6As shown, a preferred embodiment of the present invention provides a foldable handle structure that can be lifted up and down, including a handle 1, a lamp body bracket 2, a movable plate 3, a fixed plate 4, an elastic element 5, a sliding block 6, and a limiting slider 7. The fixed plate 4 is installed inside the lamp body bracket 2, and a limiting block 41 is provided on the fixed plate 4. The movable plate 3 is provided with a guide groove 31 that slides with the limiting block 41. One end of the elastic element 5 is connected to the fixed plate 4, and the other end of the elastic element 5 is connected to the movable plate 3. The sliding block 6 is connected to the movable plate 3. A sliding groove 21 is provided inside the lamp body bracket 2. The limiting slider 7 includes a sliding block 71, a sliding prism 72, and a sliding cylinder 73. The sliding block 71 is slidably disposed in the sliding groove 21 and is provided with a sliding inclined groove 711. The sliding block 6 is provided with a sliding rod 61, which passes through the sliding inclined groove 711 and is connected to the sliding inclined groove 711. 1. A sliding fit is formed, wherein the sliding prism 72 is connected between the sliding cylinder 73 and the sliding block 71, and the handle 1 is provided with a limiting hole 11 that matches the shape of the sliding prism 72; when the movable plate 3 is pressed down, the elastic element 5 is compressed, the sliding rod 61 moves downward and moves to the lower part of the sliding groove 711, simultaneously driving the limiting slider 7 to move, so that the sliding prism 72 retracts into the sliding groove 21, and the limiting hole 11 of the handle 1 can rotate with the sliding cylinder 73, preventing the handle 1 from moving excessively or coming off during rotation under the action of the sliding cylinder 73; when the movable plate 3 loses external force, the restoring force of the elastic element 5 drives the movable plate 3 to move upward, and the sliding rod 61 moves upward and moves to the upper part of the sliding groove 711, simultaneously driving the limiting slider 7 to move, so that the sliding prism 72 is inserted into the limiting hole 11 of the handle 1. In this embodiment, the elastic element 5 is a tension spring, the upper part of the fixed plate 4 is provided with a first connecting hook 42 connected to the tension spring, and the lower part of the movable plate 3 is provided with a second connecting hook 34 connected to the tension spring.

[0026] This invention utilizes a downward-pressing movable plate 3, which overcomes the elastic force of the elastic element 5. The sliding rod 61 on the sliding block 6 drives the limiting slider 7 to retract inward, causing the sliding cylinder 73 on the limiting slider 7 to engage with the limiting hole 11 on the handle 1. The handle 1 is no longer restricted by the sliding prism 72, thus unlocking it. The handle 1 can rotate to lower or retract itself. When the stage light is not needed, the handle 1 can be stored away, reducing space occupation and preventing collision damage caused by the handle 1 protruding during transportation or use. After the movable plate 3 is released, the elastic element 5 loses the resistance of external force. Under the restoring force of the elastic element 5, the elastic element 5 drives the movable plate 3 and the sliding rod 61 to move upward synchronously. During the upward movement of the sliding rod 61, the limiting slider 7 extends outward, so that the sliding prism 72 of the limiting slider 7 is inserted into the limiting hole 11 on the handle 1. At this time, the handle 1 cannot rotate under the limiting action of the sliding prism 72, thus locking the handle 1. This allows the handle 1 to be stably kept in the lifting or retracted state, ensuring that the handle 1 will not rotate or shake randomly during the lifting process. This makes it convenient to lift the stage light through the handle 1, ensuring the safety and convenience of using the handle 1.

[0027] For example, the top of the movable plate 3 is provided with a button 32, the button 32 is provided with a first magnet 12, and the handle 1 is provided with a second magnet 33 that is magnetically attracted to the first magnet 12. The button 32 allows for convenient pressing or releasing of the movable plate 3. When the handle 1 is in the stored state, the second magnet 33 on the handle 1 is magnetically attracted to the first magnet 12 on the button 32, effectively positioning the handle 1. This ensures that the handle 1 does not shake due to vibration or movement of the stage light during operation, thereby preventing the handle 1 from colliding with other parts of the stage light and causing abnormal noises. This ensures the stability and quietness of the stage light operation and improves the overall effect of the stage performance.

[0028] Furthermore, a limiting pressure plate 22 is provided inside the lamp body bracket 2. The limiting pressure plate 22 covers the slide groove 21 and forms a sliding cavity with the slide groove 21. The limiting pressure plate 22 is provided with a limiting groove 221 that cooperates with the moving rod 61. First, the limiting slider 7 is installed into the slide groove 21 of the lamp body bracket 2, and then locked in a suitable position by the limiting slider 7 to ensure that the limiting slider 7 can work stably in the sliding cavity. Preferably, the length of the slide groove 21 is greater than or equal to the length of the limiting slider 7, which facilitates the quick placement of the limiting slider 7 into the slide groove 21 and improves installation efficiency.

[0029] For example, the upper side wall of the lamp body bracket 2 is provided with a handle 1 storage groove that matches the shape of the handle 1, so as to ensure that the handle 1 can be stored in the handle 1 storage groove and prevent the handle 1 from protruding out of the lamp body bracket 2.

[0030] For example, the cross-section of the sliding prism 72 is square, and the diameter of the sliding cylinder 73 is the same as the side length of the sliding prism 72. In this way, when the handle 1 is lowered horizontally and the movable plate 3 is released, the sliding prism 72 can be inserted into the limiting hole 11 of the handle 1 more conveniently and accurately, and the handle 1 can be locked quickly and accurately.

[0031] Furthermore, the sliding cylinder 73 is rotatably connected to the sliding prism 72, which can reduce the friction between the sliding cylinder 73 and the limiting hole 11 of the handle 1.

[0032] In this embodiment, the limiting block 41 includes a screw and a self-locking nut 411. The fixing plate 4 is provided with a connecting hole. The screw passes through the connecting hole and the guide groove 31 and is threadedly connected to the self-locking nut 411. By adjusting the tightness between the self-locking nut 411 and the screw, the degree of vertical movement of the movable plate 3 on the fixing plate 4 can be controlled, ensuring that the movable plate 3 can move up and down flexibly relative to the fixing plate 4 without being too loose and affecting the stability and safety of use.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
