Description

Technical Field

[0001] The invention relates to the field of loudspeaker installation technology, specifically to a loudspeaker installation lifting device and its usage method. Background Technology

[0002] Embedded speakers are primarily used to achieve uniform and discreet audio coverage within a space, while also serving functions such as background music playback, voice broadcasting, notification prompts, and emergency announcements. They are widely used in various indoor scenarios. In commercial venues such as shopping malls, supermarkets, hotels, and office buildings, they can create a comfortable background music environment and support zoned broadcasting, promotional announcements, and emergency evacuation notifications. In public areas such as schools, hospitals, office buildings, and train stations, they can be used to announce get out of class start and end times, call numbers, locate people, and broadcast train and flight information. In home environments, they are often used in living rooms, bedrooms, kitchens, bathrooms, and balconies to create background music throughout the house.

[0003] However, the above-mentioned device still has the following problems during implementation: Existing technologies typically involve installing embedded speakers by creating holes in the ceiling, inserting the speaker into the hole, and then having the clips automatically pop open to hook onto the ceiling panel from the back. However, during embedded speaker installation, workers usually need to use climbing tools to reach the ceiling working height. Among these, A-frame ladders have limited stability and are prone to tipping over due to uneven ground or shifting center of gravity. When operating alone, wiring and fixing the speaker requires one hand, which increases the risk. Scaffolding is also time-consuming, takes up a lot of space, and affects on-site passage. Therefore, a speaker installation lifting device and its usage method are proposed to solve the above problems. Summary of the Invention

[0004] To address the problems mentioned in the background art, the purpose of this invention is to provide a lifting device for speaker installation and its usage method, which has the advantages of convenient installation and adjustment. It solves the problems that when installing embedded speakers, workers usually rely on climbing tools to reach the ceiling working height. Among these tools, the stability of the A-frame ladder is limited, and it is easy to tip over due to uneven ground and shift in the center of gravity. When operating alone, wiring and fixing the speaker requires one hand, which is even more risky. Furthermore, scaffolding is time-consuming, occupies a lot of space, and affects on-site passage.

[0005] To achieve the above objectives, the invention provides the following technical solution: a speaker mounting lifting device and its usage method, comprising a pole, a first mounting groove, a moving hole and a second mounting groove, wherein the first mounting groove is opened at the bottom of the inner cavity of the pole, the moving hole is opened on the left and right sides of the first mounting groove, and the second mounting groove is opened at the top of the inner cavity of the pole; The front and rear sides of the upright are fixedly connected to connecting plates, the top of the upright is movably connected to a placement plate, the top of the placement plate is provided with a mating groove, the inner cavity of the mating groove is movably connected to a device body, the four corners of the surface of the device body are provided with limit grooves, and the four corners of the inner cavity of the placement plate are provided with receiving grooves. A control component, wherein the control component is disposed within the cavity of the first mounting slot; Four spring-loaded components are provided on the left and right sides of the upright; A positioning component is disposed within the cavity of the receiving groove.

[0006] As a preferred embodiment of the invention, the control component includes a first motor, the top of which is fixedly connected to the inner wall of the first mounting groove, the output end of which is fixedly connected to a first screw, a screw sleeve block is sleeved on the surface of the first screw, the front and rear sides of the screw sleeve block are both through moving holes and fixedly connected with teeth, and there are multiple teeth, and a gear is meshed on the side of the teeth away from the screw sleeve block.

[0007] As a preferred embodiment of the invention, the rebound assembly includes a fixed shell, the fixed shell being fixedly connected to the connecting plate on the side near the connecting plate, rotating rods being fixedly connected to both the left and right sides of the gear, the rotating rods passing through the connecting plate and being fixedly connected to a rotating plate on the side near the fixed shell, a torsion spring being sleeved on the surface of the rotating rods, the torsion springs being fixedly connected to the connecting plate on the side near the connecting plate, and the torsion springs being fixedly connected to the rotating plate on the side near the rotating plate.

[0008] As a preferred embodiment of the invention, a connecting pipe is fixedly connected to the top of the gear, and support legs are fixedly connected to both the left and right sides of the connecting pipe.

[0009] As a preferred embodiment of the invention, a second motor is fixedly connected to the bottom of the inner cavity of the second mounting slot, a hollow plate is movably connected to the inner cavity of the second mounting slot, a second screw is fixedly connected to the output end of the second motor, the top of the second screw passes through the hollow plate and is threadedly connected to the hollow plate, and the top of the hollow plate passes through the second mounting slot and is fixedly connected to the placement plate.

[0010] As a preferred embodiment of the invention, the top of the placement plate is provided with a groove, and there are multiple grooves, with an infrared lamp fixedly installed at the bottom of the inner cavity of the groove.

[0011] As a preferred embodiment of the invention, the positioning component includes a movable block, the top of which has a pressing groove, the inner cavity of which is movably connected to the pressing block, a limiting rod that cooperates with the limiting groove is fixedly connected to the side of the pressing block near the groove, the side of the limiting rod away from the pressing block passes through the receiving groove and extends into the inner cavity of the slot, and a spring is fixedly connected to the side of the movable block away from the limiting rod.

[0012] As a preferred embodiment of the invention, the top of the placement plate is provided with an anastomosis groove, and the number of anastomosis grooves is four. The inner cavity of the anastomosis groove is movably connected to a linkage block, and the bottom of the linkage block is fixedly connected to a linkage rod. The bottom of the linkage rod passes through the anastomosis groove and is fixedly connected to the compression block.

[0013] When it is necessary to install the speaker on the ceiling, hold the upright firmly with your hand to move the lifting device to the appropriate position, and then turn on the first motor to drive the first screw to rotate. The rotation of the first screw will drive the screw sleeve block to rise. Step 2: The movement of the screw sleeve block will cause the teeth to mesh with the gear, the rotation of the gear will cause the rotating rod to rotate, the rotation of the rotating rod will cause the rotating plate to twist the torsion spring, the rotation of the gear will also cause the connecting pipe to rotate, and the rotation of the connecting pipe will cause the support leg to contact the ground. Step 3: Then turn on the infrared spotlight in the groove. The red light emitted by the infrared spotlight will form a ring, which can help align with the hole at the bottom of the ceiling panel. Step 4: After aligning the placement plate with the hole at the bottom of the ceiling panel, pick up the device and place it in the mating groove at the top of the placement plate. Then, pull up the linkage block to move the linkage rod. The movement of the linkage rod will cause the pressing block to rise. At this time, the spring will undergo elastic deformation, causing the movable block to move. The movement of the movable block will cause the limiting rod to insert into the limiting groove, thus fixing the position of the device. Step 5: Then turn on the second motor to drive the second screw to rotate, which will move the hollow plate. The movement of the hollow plate will cause the placement plate to rise, and the rise of the placement plate will cause the device to be inserted into the hole at the bottom of the ceiling panel. Step 6: After the placement plate comes into contact with the ceiling plate, the ceiling plate will press down the linkage block, linkage rod and pressing block. The pressing block presses down on the inclined surface of the pressing groove, which will drive the movable block to move. The movement of the movable block will drive the limit rod to disengage from the limit groove. Then the second screw will drive the placement plate to descend, and the device body will pop out the claw in the hole, thus completing the installation of the device body.

[0014] Compared with existing technologies, the beneficial effects of the invention are as follows: 1. The invention solves the problems of the following when installing embedded speakers: workers usually need to use climbing tools to reach the ceiling working height. Among them, the stability of the A-frame ladder is limited and it is easy to tip over due to uneven ground and shift of the center of gravity. When a single person is operating, wiring and fixing the speaker requires one hand, which is even more risky. The scaffolding is time-consuming and takes up a lot of space, affecting the passage on site. The invention achieves the effect of convenient installation and adjustment by setting up control components, spring-loaded components, positioning components, first motor, first screw, screw sleeve block, teeth, gear, fixed shell, rotating rod and rotating plate.

[0015] 2. By setting up the second embodiment, the invention converts the rotational motion of the motor into the unfolding action of the support leg. There is no need for manual support setup. The ground contact of the support leg can be completed with one click. The cooperation of the torsion spring, rotating rod and rotating plate in the rebound assembly allows the support leg to automatically retract after the installation is completed through the elastic rebound of the torsion spring. There is no need for manual disassembly of the support structure. The connection design between the connecting pipe and the support leg realizes the synchronous linkage between the gear rotation and the unfolding of the support leg, ensuring the consistency of the unfolding of the support legs on both sides and further improving the support stability of the device.

[0016] 3. The invention, through the third embodiment, employs a threaded linkage design between the second motor, the second screw, and the hollow plate to provide stable and controllable vertical lifting power for the placement plate and the speaker. This allows for precise adjustment of the speaker's rising height, enabling smooth insertion into the ceiling opening. The infrared spotlight, through a ring formed by red light, achieves rapid and accurate alignment between the placement plate and the bottom opening of the ceiling panel, eliminating the need for repeated manual climbing and verification. The elastic deformation of the spring positions the limiting rod. When the placement plate contacts the ceiling, the ceiling automatically presses against the linkage block, causing the limiting rod to disengage from the limiting groove, thus automatically unlocking the speaker. Combined with the descent of the placement plate, the speaker's claws can smoothly pop out and hook onto the ceiling panel, completing the fixed installation. The entire process requires no manual unlocking. Attached Figure Description

[0023] Example 1 Reference Figure 1-6 The invention provides a speaker mounting lifting device and its usage method, including a pole 1, a first mounting groove 2, a moving hole 3 and a second mounting groove 4. The first mounting groove 2 is opened at the bottom of the inner cavity of the pole 1, the moving hole 3 is opened on the left and right sides of the first mounting groove 2, and the second mounting groove 4 is opened at the top of the inner cavity of the pole 1. The front and rear sides of the upright 1 are fixedly connected with connecting plates 5. The top of the upright 1 is movably connected with a placement plate 6. The top of the placement plate 6 is provided with a mating groove 7. The inner cavity of the mating groove 7 is movably connected with a device body 8. The four corners of the surface of the device body 8 are provided with limit grooves 9. The four corners of the inner cavity of the placement plate 6 are provided with receiving grooves 10. Control component 11 is disposed in the inner cavity of the first mounting slot 2; Four spring-loaded components 12 are provided on the left and right sides of the upright 1. Positioning component 13 is disposed in the inner cavity of receiving groove 10.

[0024] Specifically, the lifting device abandons the traditional form of use of climbing tools and integrates the speaker's load-bearing, lifting, and positioning operations into a single device. From the structural design level, it solves the core problems of poor stability of A-frame ladders and time-consuming and space-consuming scaffolding erection.

[0025] Example 2 A second embodiment of the invention provides a speaker mounting lifting device and its usage method. The control component 11 includes a first motor 111, the top of which is fixedly connected to the inner wall of a first mounting groove 2. A first screw 112 is fixedly connected to the output end of the first motor 111. A screw sleeve block 113 is sleeved on the surface of the first screw 112. The front and rear sides of the screw sleeve block 113 pass through a moving hole 3 and are fixedly connected with teeth 114. There are multiple teeth 114. A gear 115 is meshed on the side of the teeth 114 away from the screw sleeve block 113. The spring-loaded component 12 includes a fixed... The housing 121 is fixedly connected to the connecting plate 5 on the side near the connecting plate 5. The gear 115 is fixedly connected to the left and right sides of the gear 122. The rotating rod 122 passes through the connecting plate 5 and is fixedly connected to the rotating plate 123 on the side near the fixed housing 121. A torsion spring 124 is sleeved on the surface of the rotating rod 122. The torsion spring 124 is fixedly connected to the connecting plate 5 on the side near the connecting plate 5 and fixedly connected to the rotating plate 123 on the side near the rotating plate 123. A connecting tube 14 is fixedly connected to the top of the gear 115. Support legs 15 are fixedly connected to the left and right sides of the connecting tube 14.

[0026] Specifically, by setting up the second embodiment, the rotational motion of the motor is converted into the unfolding action of the support leg 15. There is no need for manual support setup. The ground contact of the support leg 15 can be completed with one click. The cooperation of the torsion spring 124, the rotating rod 122, and the rotating plate 123 in the rebound assembly 12 allows the support leg 15 to automatically retract after the installation is completed through the elastic rebound of the torsion spring 124. There is no need for manual disassembly of the support structure. The connection design between the connecting pipe 14 and the support leg 15 realizes the synchronous linkage between the rotation of the gear 115 and the unfolding of the support leg 15, ensuring the consistency of the unfolding of the support legs 15 on both sides and further improving the support stability of the device.

[0027] Furthermore, when it is necessary to install the speaker on the ceiling, hold the upright 1 firmly to move the lifting device to the appropriate position, then turn on the first motor 111 to drive the first screw 112 to rotate. The rotation of the first screw 112 will drive the screw sleeve block 113 to rise. The movement of the screw sleeve block 113 will drive the teeth 114 to mesh with the gear 115. The rotation of the gear 115 will drive the rotating rod 122 to rotate. The rotation of the rotating rod 122 will drive the rotating plate 123 to twist the torsion spring 124. When the gear 115 rotates, it will also drive the connecting pipe 14 to rotate. The rotation of the connecting pipe 14 will drive the support leg 15 to contact the ground.

[0028] Example 3 A third embodiment of the invention provides a speaker mounting lifting device and its usage method. A second motor 16 is fixedly connected to the bottom of the inner cavity of a second mounting groove 4. A hollow plate 17 is movably connected to the inner cavity of the second mounting groove 4. A second screw 18 is fixedly connected to the output end of the second motor 16. The top of the second screw 18 passes through the hollow plate 17 and is threadedly connected to it. The top of the hollow plate 17 passes through the second mounting groove 4 and is fixedly connected to a placement plate 6. The top of the placement plate 6 has multiple grooves 19. An infrared spotlight 20 is fixedly installed at the bottom of the inner cavity of each groove 19. The positioning component 13 includes a movable block 131. The top of the movable block 131 has... The device is provided with a compression groove 132, and a compression block 133 is movably connected to the inner cavity of the compression groove 132. A limiting rod 134 that works with the limiting groove 9 is fixedly connected to the side of the compression block 133 near the groove 19. The side of the limiting rod 134 away from the compression block 133 passes through the receiving groove 10 and extends into the inner cavity of the slot. A spring 135 is fixedly connected to the side of the movable block 131 away from the limiting rod 134. A matching groove 21 is provided on the top of the placement plate 6, and there are four matching grooves 21. A linkage block 22 is movably connected to the inner cavity of the matching groove 21. A linkage rod 23 is fixedly connected to the bottom of the linkage block 22. The bottom of the linkage rod 23 passes through the matching groove 21 and is fixedly connected to the compression block 133.

[0029] Specifically, through the threaded linkage design of the second motor 16, the second screw 18, and the hollow plate 17 in the third embodiment, a stable and controllable vertical lifting power is provided for the placement plate 6 and the speaker. The rising height of the speaker can be precisely adjusted so that the speaker can be smoothly inserted into the ceiling opening. The setting of the infrared spotlight 20 enables the placement plate 6 to be quickly and accurately aligned with the bottom opening of the ceiling plate through the ring formed by the red light, without the need for manual repeated climbing to check the position. The elastic deformation of the spring 135 can position the limit rod 134. When the placement plate 6 contacts the ceiling, the ceiling will automatically squeeze the linkage block 22 to drive the limit rod 134 to disengage from the limit groove 9, realizing the automatic unlocking of the speaker. With the descent action of the placement plate 6, the speaker's claws can be smoothly ejected and hooked onto the ceiling plate to complete the fixed installation. The whole process does not require manual unlocking.

[0030] Furthermore, the infrared spotlight 20 inside the groove 19 is turned on. The red light emitted by the infrared spotlight 20 forms a ring, which helps to align with the hole at the bottom of the ceiling panel. After the placement plate 6 is aligned with the hole at the bottom of the ceiling panel, the device 8 is picked up and placed in the mating groove 7 on the top of the placement plate 6. Then, the linkage block 22 is pulled up to move the linkage rod 23. The movement of the linkage rod 23 will cause the pressing block 133 to rise. At this time, the spring 135 will undergo elastic deformation, causing the movable block 131 to move. The movement of the movable block 131 will cause the limiting rod 134 to insert into the limiting groove 9. At this time, the position of the device 8 can be fixed, and then it can be turned on. The second motor 16 drives the second screw 18 to rotate, which in turn moves the hollow plate 17. The movement of the hollow plate 17 causes the placement plate 6 to rise, and the rising placement plate 6 causes the device body 8 to be inserted into the hole at the bottom of the ceiling panel. After the placement plate 6 contacts the ceiling panel, the ceiling panel will press down the linkage block 22, linkage rod 23 and pressing block 133. The pressing block 133 presses down on the inclined surface of the pressing groove 132, which will cause the movable block 131 to move. The movement of the movable block 131 will cause the limiting rod 134 to disengage from the limiting groove 9. Then the second screw 18 drives the placement plate 6 to fall, and the device body 8 pops out the claw in the hole, thus completing the installation of the device body 8.

[0031] Working principle: When the speaker needs to be installed on the ceiling, hold the upright 1 firmly to move the lifting device to the appropriate position. Then, turn on the first motor 111 to rotate the first screw 112. The rotation of the first screw 112 will cause the screw sleeve block 113 to rise. The movement of the screw sleeve block 113 will cause the teeth 114 to mesh with the gear 115. The rotation of the gear 115 will cause the rotating rod 122 to rotate. The rotation of the rotating rod 122 will cause the rotating plate 123 to twist the torsion spring 124. When the gear 115 rotates, it will also cause the connecting pipe 14 to rotate. The rotation of the connecting pipe 14 will cause the support leg 15 to contact the ground. Then, turn on the infrared spotlight 20 in the groove 19. The red light emitted by the infrared spotlight 20 will form a ring, which can help align with the hole at the bottom of the ceiling panel. After the placement plate 6 is aligned with the hole at the bottom of the ceiling panel, pick up the device 8 and place it in the mating groove 7 on the top of the placement plate 6. Then, pull up the linkage block 22 to drive the linkage rod 23. The movement of the linkage rod 23 causes the pressing block 133 to rise. At this time, the spring 135 will undergo elastic deformation, causing the movable block 131 to move. The movement of the movable block 131 will cause the limiting rod 134 to insert into the limiting groove 9, thus fixing the position of the device body 8. Then, the second motor 16 is turned on to drive the second screw 18 to rotate, which will drive the hollow plate 17 to move. The movement of the hollow plate 17 will cause the placement plate 6 to rise. The rise of the placement plate 6 will cause the device body 8 to be inserted into the hole at the bottom of the ceiling plate. After the placement plate 6 contacts the ceiling plate, the ceiling plate will press the linkage block 22, linkage rod 23 and pressing block 133 to fall. The pressing block 133 presses the inclined surface of the pressing groove 132, which will cause the movable block 131 to move. The movement of the movable block 131 will cause the limiting rod 134 to disengage from the limiting groove 9. Then, the second screw 18 will drive the placement plate 6 to fall. The device body 8 will pop out the claw in the hole, thus completing the installation of the device body 8.

[0032] In summary, the coordination of the control component 11, the springback component 12, the positioning component 13, the first motor 111, the first screw 112, the screw sleeve block 113, the teeth 114, the gear 115, the fixed shell 121, the rotating rod 122, and the rotating plate 123 achieves the effect of convenient installation and adjustment.

9. A method of using a speaker installation lifting device as described in any one of claims 1 to 8, comprising the following steps: Step 1: When it is necessary to install the speaker on the ceiling, hold the upright (1) firmly with your hand to move the lifting device to a suitable position, and then turn on the first motor (111) to drive the first screw (112) to rotate. The rotation of the first screw (112) will drive the screw sleeve block (113) to rise. Step 2: The movement of the screw sleeve block (113) will cause the teeth (114) to mesh with the gear (115). The rotation of the gear (115) will cause the rotating rod (122) to rotate. The rotation of the rotating rod (122) will cause the rotating plate (123) to twist the torsion spring (124). When the gear (115) rotates, it will also cause the connecting pipe (14) to rotate. The rotation of the connecting pipe (14) will cause the support leg (15) to contact the ground. Step 3: Then turn on the infrared spotlight (20) in the groove (19). The red light emitted by the infrared spotlight (20) will form a ring, which can help align with the hole at the bottom of the ceiling panel. Step 4: After the placement plate (6) is aligned with the hole at the bottom of the ceiling board, pick up the device (8) and place it in the mating groove (7) at the top of the placement plate (6). Then pull up the linkage block (22) to drive the linkage rod (23) to move. The movement of the linkage rod (23) will drive the pressing block (133) to rise. At this time, the spring (135) will undergo elastic deformation to drive the movable block (131) to move. The movement of the movable block (131) will drive the limiting rod (134) to insert into the limiting groove (9). At this time, the position of the device (8) can be fixed. Step 5: Then turn on the second motor (16) to drive the second screw (18) to rotate, which will drive the hollow plate (17) to move. The movement of the hollow plate (17) will drive the placement plate (6) to rise. The rise of the placement plate (6) will drive the body (8) to be inserted into the hole at the bottom of the ceiling plate. Step 6: After the placement plate (6) comes into contact with the ceiling plate, the ceiling plate will press down the linkage block (22), linkage rod (23) and pressing block (133). The pressing block (133) presses down the inclined surface of the pressing groove (132), which will drive the movable block (131) to move. The movement of the movable block (131) will drive the limit rod (134) to disengage from the limit groove (9). Then the second screw (18) will drive the placement plate (6) to descend, and the device body (8) will pop out the claw in the hole, thus completing the installation of the device body (8).
