[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0019] like Figure 1-6 As shown, a locking structure in this embodiment includes a base 10 and a vertical plate 2 mounted on the base 10; the vertical plate 2 is provided with a lifting spring 31, a lifting slide 32, and a slider 33 slidably connected to the lifting slide 32; the slider 33 is provided with a connecting component 7 for connecting to a projector; one end of the lifting spring 31 is mounted on the vertical plate 2; the other end of the lifting spring 31 is connected to the slider 33; the slider 33 is provided with a slot 331; the vertical plate 2 is also provided with a button assembly and a locking block 41 for assembling with the slot 331; the button assembly is used to engage or disengage the locking block 41 from the slot 331.
[0020] Specifically, the base 10 serves as the foundation of the entire structure, ensuring overall stability. The slider 33 can slide up and down within the lifting groove 32, allowing the user to adjust the projector's height as needed. The connecting component 7 on the slider 33 is used to directly or indirectly fix the projector.
[0021] When the slider 33 is adjusted to the desired height, the position of the slider 33 is fixed by inserting the locking block 41 into the locking groove 331 on the slider 33, preventing it from shifting due to external force or vibration. Specifically, when the locking block 41 engages with the locking groove 331, it locks the current position of the slider 33; when the locking block 41 disengages from the locking groove 331, it is in an unlocked state, and the slider 33 can slide freely up and down along the lifting slide 32.
[0022] In addition, the number of slots 331 is one or more; when there are two or more slots 331, the multiple slots 331 are arranged sequentially along the lifting direction; when multiple slots 331 are provided, the projector can also have a height adjustment function. Specifically, when fully unlocked (at this time, the projector is at its highest position), the user can directly press the projector to move it downwards, and release the hand at a suitable height. The locking block 41 will automatically lock into the slot 331 closest to the locking block 41 under the force of the reset torsion spring 45.
[0023] The advantage of this design is that users can unlock slider 33 with a simple operation (pressing the button assembly), then adjust the projector's height manually or with the help of the lifting spring 31, and finally press the button again to make the locking block 41 re-engage in the slot 331 on slider 33 to fix the projector in its new position. This mechanism is both convenient and safe, and is suitable for occasions where frequent height adjustments are required.
[0024] like Figure 4 As shown, for better projector storage, the following configuration can be implemented: When the projector is not in use, rotate it so that the projection lens 61 faces the base 10, then press the projector down to bring it close to the base 10 until it is flush against it. At this point, the locking block 41 engages with the locking slot 331, locking the current storage state. The top surface of the base 10 is slightly concave to ensure it can fully accommodate the projection lens 61, thus protecting it. Figure 5 As shown, when the button assembly is pressed, the locking block 41 disengages from the locking slot 331, entering the unlocked state. Under the lifting action of the lifting spring 31, the projector body 6 separates from the base 10. Figure 6 As shown, adjust the angle of the projector body 6 according to actual needs to expose the projection lens 61, and projection can begin.
[0025] like Figure 1-3 As shown, in this embodiment, a locking structure is provided, wherein the slot 331 is provided on the side of the slider 33; the lifting slide 32 is provided with a clearance hole 42 corresponding to the position of the slot 331; and the locking block 41 is telescopically disposed in the clearance hole 42.
[0026] The function of the clearance hole 42 is to provide a channel for the locking block 41, so that the locking block 41 can pass through the vertical plate 2 and extend into the locking groove 331 of the slider 33 or exit from the locking groove 331.
[0027] like Figure 1-3 As shown, in this embodiment, a locking structure is provided. The button assembly includes a locking rod 43, a rotating shaft 44, a reset torsion spring 45, and a pressing block 46. The middle portions of the reset torsion spring 45 and the locking rod 43 are both mounted on the vertical plate 2 via the rotating shaft 44. The two ends of the reset torsion spring 45 are respectively connected to the locking rod 43 and the vertical plate 2. The pressing block 46 is mounted on the vertical plate 2. One end of the locking rod 43 is connected to the pressing block 46. The other end of the locking rod 43 is connected to the locking block 41.
[0028] The locking lever 43 can rotate around the pivot 44. One end of the locking lever 43 is connected to the pressing block 46, and the other end is connected to the locking block 41. When the user presses the pressing block 46, the locking lever 43 rotates around the pivot 44, thereby actuating the locking block 41. When the pressing block 46 is released, under the force of the return torsion spring 45, the locking block 41 can press against the side of the slot 331 or the slider 33, fixing the current position of the slider 33.
[0029] When the user presses the pressing block 46, it pushes the locking rod 43 to rotate around the pivot 44, overcoming the force of the reset torsion spring 45, causing the locking block 41 to retract, thus allowing the slider 33 to slide freely; when the user releases the pressing block 46, the locking block 41 will try to engage with the slot 331 on the slider 33 again under the action of the reset torsion spring 45, and once aligned and engaged, it will automatically lock the current position of the slider 33.
[0030] The above design improves the ease of use of the equipment, and also enhances the stability of the system and the user experience.
[0031] like Figure 1-3 As shown, in this embodiment, a locking structure is provided, wherein the lifting slide 32 is provided on the front side of the vertical plate 2; the vertical plate 2 is also provided with a first strip groove 51; the lifting slide 32 is provided with a second strip groove 52 corresponding to the position of the first strip groove 51; one end of the connecting component 7 is connected to the slider 33; the other end of the connecting component 7 passes through the second strip groove 52 and the first strip groove 51 in sequence and extends to the back side of the vertical plate 2; the projector is connected to the other end of the connecting component 7 and installed on the back side of the vertical plate 2.
[0032] Specifically, the dimensions of the first slot 51 and the second slot 52 should precisely match the diameter of the connecting component 7 to ensure that the connecting component 7 can pass smoothly without unnecessary friction or loosening. This configuration allows the projector to be directly mounted on the back of the vertical plate 2, thus hiding it behind the plate and saving space. During use, pressing the button assembly on the front of the vertical plate 2 allows for the control of raising and lowering the projector from the back of the plate 2.
[0033] In addition, the first strip groove 51 and the second strip groove 52 also serve as limiting functions, limiting the lifting distance of the slider 33 on the lifting groove 32.
[0034] like Figure 1-3 As shown in the figure, in one locking structure of this embodiment, the number of lifting springs 31 is two.
[0035] With the above settings, the overall structure is more stable, ensuring that the slider 33 can move up and down smoothly and reliably on the vertical plate 2. Specifically, the elasticity of the lifting spring 31 should be moderate, providing sufficient support (to ensure that the projector is lifted) while avoiding excessive elasticity that would cause it to bounce up too quickly.
[0036] like Figure 1-3 As shown, in this embodiment of the locking structure, the vertical plate 2 is provided with a mounting groove 21 for accommodating the lifting spring 31; the bottom of the slider 33 is provided with a guide block 332; the top end of the lifting spring 31 is sleeved on the guide block 332; and the bottom end of the lifting spring 31 is connected to the mounting groove 21.
[0037] The design of mounting slot 21 and guide block 332 makes the entire system structure more compact, saves space, and also improves the overall aesthetics.
[0038] like Figure 3 As shown, in this embodiment of the locking structure, the inner wall of the slot 331 is provided with a guide groove.
[0039] Specifically, when the user releases the button assembly, the reset torsion spring 45 causes the locking rod 43 to move the locking block 41 to attempt to re-insert into the slot 331 on the slider 33. At this time, the front end of the locking block 41 will first contact the guide groove at the entrance of the slot 331. The design of the guide groove can gradually guide the locking block 41 to slide into the slot 331 along the inclined surface, reducing the possibility of the locking block 41 directly hitting the inner wall of the slot 331, and ensuring that the locking block 41 can enter the slot 331 smoothly and accurately.
[0040] like Figure 3-6 As shown, in this embodiment, a locking structure is provided, wherein the vertical plate 2 is installed on one side of the base 10; the horizontal projection of the vertical plate 2 and the base 10 forms an "L" shape.
[0041] The above setup is simple and compact, making full use of space.
[0042] like Figure 3-6 As shown, a rotating projector of this embodiment includes a body 6 and the aforementioned locking structure; the body 6 is mounted on the connecting assembly 7; the vertical plate 2 is also provided with a power interface 22 for supplying power to the body 6.
[0043] The projector can be connected to an external power source via a power cord to obtain the power required for operation. This design allows the projector to operate stably without a built-in battery and enables flexible selection of installation locations based on the needs of the installation environment.
[0044] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
