Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, a speaker with a height-adjustable projector includes a cabinet 100 for playing audio. The top of the cabinet 100 has a receiving slot 110, within which a projector 120 is housed. The projector 120 works in conjunction with the cabinet 100 to achieve synchronized playback of images and audio, adding more functionality to the speaker. The receiving slot 110 can store the projector 120. When not in use, the projector 120 is located within the receiving slot 110, improving the overall appearance of the cabinet 100. Simultaneously, the receiving slot 110 also protects the projector 120, reducing the possibility of damage.

[0026] like Figure 1 , 2As shown in Figure 3, the housing 100 is equipped with a lifting rod 200. The lifting rod 200 is used to drive the projector 120 to move up and down. When the lifting rod 200 is in the retracted state, the projector 120 is lowered into the receiving slot 110 for storage. When the lifting rod 200 is in the extended state, the projector 120 is raised from the receiving slot 110, and the user can use the projector 120 to project. The lifting rod 200 includes a cavity tube 210 fixedly installed inside the housing 100. A pressure rod 220 is slidably connected inside the cavity tube 210. A piston 221 is provided at the end of the pressure rod 220. The pressure rod 220 drives the piston 221 to slide inside the cavity tube 210. The cavity tube 210 and the pressure rod 220 work using the principle of air pressure. When there is no external force, the air pressure inside the cavity tube 210 pushes the piston 221 to rise, and the pressure rod 220 will always remain in the raised state. When the pressure rod 220 is under pressure, the pressure rod 220 will push the piston 221 to compress air and descend. When the pressure rod 220 is not affected by external force, the pressure rod 220 will rise again.

[0027] like Figure 3 As shown, the lifting rod 200 also includes a lower sleeve 230 and an upper sleeve 240. The cavity tube 210 is located inside the lower sleeve 230, and one end of the cavity tube 210 is connected to one end of the lower sleeve 230. The pressure rod 220 is located inside the upper sleeve 240, and one end of the pressure rod 220 is connected to one end of the upper sleeve 240. The upper sleeve 240 slides between the lower sleeve 230 and the cavity tube 210. The top end of the lower sleeve 230 is provided with a fixing plate 231, which is connected to the bottom of the receiving groove 110. Through the connection between the fixing plate 231 and the end of the cavity tube 210 and the housing 100, it can be ensured that the lifting rod 200 always remains vertical inside the housing 100. The upper sleeve 240 and the lower sleeve 230 are used to maintain the connection stability of the cavity tube 210 and the pressure rod 220, ensure that the pressure rod 220 and the cavity tube 210 always remain in a straight state, and improve the airtightness inside the cavity tube 210 to avoid air pressure drop.

[0028] like Figure 2 , 4 As shown, the end of the pressure rod 220 is connected to a pitch adjustment mechanism 300, which is connected to the projector 120. The pitch adjustment mechanism 300 includes a connecting plate 320 and a hinge seat 310. The hinge seat 310 is connected to the top of the pressure rod 220, and the connecting plate 320 is hinged to the hinge seat 310. The projector 120 is fixedly connected to the connecting plate 320. The pitch adjustment mechanism 300 can be used to adjust the pitch angle of the projector 120, so that the user can adjust the projected image.

[0029] like Figure 3 , 5As shown, the cavity tube 210 and the pressure rod 220 are provided with a lifting locking mechanism 400 for locking the lifting rod 200 in the retracted state. The lifting locking mechanism 400 comprises a rotating ring 410 sleeved on the top end of the pressure rod 220, and the outer wall of the rotating ring 410 is provided with a plurality of first protrusions 411 which are acute triangle structures and have one side surface vertically arranged. The inner wall of the top end of the cavity tube 210 is fixed with a locking ring 420, and the inner wall of the top end of the locking ring 420 is provided with a plurality of second protrusions 421, and a sliding groove 412 for the first protrusions 411 to pass through is arranged between two adjacent second protrusions 421. The top end of the second protrusion 421 is provided with a guide surface 4211 for matching the bottom side inclined surface of the first protrusion 411. When the user needs to store the projector 120, the projector 120 can be pressed to push the pressure rod 220 to descend, and the pressure rod 220 drives the rotating ring 410 to descend. When the first protrusions 411 continuously descend and contact the second protrusions 421, the guide surface 4211 at the top end of the second protrusion 421 matches the inclined surface at the bottom side of the first protrusion 411 to drive the rotating ring 410 to rotate, so that the first protrusion 411 smoothly passes through the sliding groove 412.

[0030] As Figure 5As shown, the bottom end of the second protrusion 421 is provided with a bayonet 4212 for fixing the first protrusion 411, the bayonet 4212 is a triangular structure matched with the top end of the first protrusion 411, when the first protrusion 411 passes through the sliding slot 412 and descends below the second protrusion 421, as long as the rotating ring 410 is rotated, the first protrusion 411 corresponds to the bayonet 4212, the bayonet 4212 can fix the first protrusion 411, lock the rotating ring 410, and then realize the locking of the pressing rod 220, at this time the projector 120 cannot be pushed up by the pressing rod 220, and remains in the storage state. The inner wall of the locking ring 420 is provided with a convex ring 422 for driving the rotating ring 410 to rotate, the top end of the convex ring 422 is provided with a plurality of first and second convex corners 4221 and 4222 arranged at intervals, the first convex corner 4221 is higher than the second convex corner 4222, the top end of the first convex corner 4221 corresponds to the sliding slot 412, and the top end of the second convex corner 4222 corresponds to the bayonet 4212. The side surface of each of the first and second convex corners 4221 and 4222 is a vertical surface, and the other side surface is an inclined surface, and the inclined surfaces of the first and second convex corners 4221 and 4222 are consistent in inclination direction. When the user presses the projector 120, the first protrusion 411 passes through the sliding slot 412 and descends to contact the first convex corner 4221, the inclined surface of the first convex corner 4221 cooperates with the inclined surface on the bottom side of the first protrusion 411 to drive the rotating ring 410 to rotate, after the rotating ring 410 rotates, the top end of the first protrusion 411 corresponds to the bayonet 4212, when the air pressure in the cavity tube 210 pushes the pressing rod 220 to rise, the bayonet 4212 can block the first protrusion 411, prevent the pressing rod 220 from rising, and realize the locking of the lifting rod 200 in the retracted state.

[0031] It should be noted that the bayonet 4212 is a triangular structure matched with the top end of the first protrusion 411, so the bayonet 4212 also consists of an inclined surface and a vertical surface, and the inclined surface of the bayonet 4212 is consistent in inclination direction with the upper inclined surface of the first protrusion 411. When the top end of the first protrusion 411 contacts the inclined surface of the bayonet 4212, the inclined surface of the bayonet 4212 cooperates with the upper inclined surface of the first protrusion 411 to drive the rotating ring 410 to rotate, so that the first protrusion 411 slides into the bayonet 4212, and the vertical surface of the bayonet 4212 can limit the sliding of the first protrusion 411. When the first convex corner 4221 drives the rotating ring 410 to rotate, the vertical surface of the second convex corner 4222 limits the rotation angle of the rotating ring 410, when the vertical surface of the first protrusion 411 contacts the vertical surface of the second convex corner 4222, the top end of the first protrusion 411 is just rotated below the inclined surface of the bayonet 4212, when the pressing rod 220 rises, the top end of the first protrusion 411 can be clamped into the bayonet 4212.

[0032] When the top end of the first protrusion 411 is in contact with the inclined surface of the second protrusion 4222, the first protrusion 411 slides into the socket 4212, and the rotating ring 410 generates a certain rotation, at this time, the inclined surface of the second protrusion 4222 corresponds to the bottom end of the first protrusion 411, when the user presses the projector 120 again, the pressure rod 220 drives the rotating ring 410 to descend, the bottom end of the first protrusion 411 is in contact with the inclined surface of the second protrusion 4222, the second protrusion 4222 drives the rotating ring 410 to rotate again, at this time, the top end of the first protrusion 411 rotates to the position corresponding to the sliding groove 412, the first protrusion 411 can pass through the sliding groove 412 smoothly, and the pressure rod 220 can drive the projector 120 to ascend smoothly, so that the user can use the projector 120 normally.

[0033] Based on the working principle of the lifting locking mechanism 400, in the embodiment, the user only needs to press the projector 120, and then the lifting locking mechanism 400 can control the lifting of the projector 120, so that the operation is very simple, and meanwhile, the lifting rod 200 and the lifting locking mechanism 400 in the embodiment have the advantages of simple structure, low production cost, simple and reliable structure, and convenience for production and popularization.

[0034] The above embodiment is a preferred implementation manner of the utility model, and is not a limitation on the utility model, and any obvious replacement without departing from the utility model concept is within the protection scope of the utility model.
