Description

Technical Field

[0001] This invention belongs to the field of lamp installation technology, specifically a lamp gripping and mounting mechanism. Background Technology

[0002] A lamp tube is a type of lighting device with many varieties and wide applications. A lamp tube usually refers to a straight fluorescent lamp, but due to the specific nature of the term, it now also refers to a lamp with a long tube shape. An LED lamp tube refers to a lamp tube that uses LEDs as the light source.

[0003] 1. Tubular lamps (ordinary fluorescent tubes): Traditional fluorescent tubes emit light through argon and mercury vapor inside the tube under the action of an electric current, and then the light is converted into visible light by phosphors. The thinner the tube, the higher the efficiency. For example, T5 fluorescent tubes are gradually replacing T8 fluorescent tubes.

[0004] 2. LED tubes: Using LEDs as the light source, LED tubes have advantages such as energy saving, low price, long life, drop resistance and simple structure. Compared with traditional fluorescent tubes, LED tubes are more environmentally friendly and are a good alternative to fluorescent tubes in the future.

[0005] 3. Ultraviolet lamps: Low-pressure ultraviolet lamps are mainly used for sterilization and disinfection, and can also be used for ultraviolet testing, medical treatment, etc. High-pressure ultraviolet lamps are suitable for high-requirement indoor lighting. They are made of excellent materials and have a wide effective spectral range.

[0006] Currently, regardless of the type of light tube used in home decoration, its installation requires manual fixing. However, because some light tubes are quite long, it is impossible for the installer to fix the light tube into the light cover plate in one go. Moreover, the length makes it difficult to control the light tube, and the installation operation cannot be completed quickly. At the same time, the installation process may cause tilting and swinging. Once the light tube swings, it may collide with the wall, which may damage the surface of the light tube. Summary of the Invention

[0007] To address the problems mentioned in the background section, the present invention provides a lamp tube gripping and mounting mechanism.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a lamp tube gripping and mounting mechanism, comprising two U-shaped groove plates, two groove plate frames fixedly connected between the two U-shaped groove plates, a set of telescopic plates symmetrically and slidably connected to the inner walls of the two U-shaped groove plates, and arc-shaped convex rubber plates symmetrically provided on the top end of each of the two sets of telescopic plates. The lamp tube body is intermittently and tightly connected between the inner walls of one end of the two sets of arc-shaped convex rubber plates, and each of the two sets of telescopic plates is also provided with an elastic telescopic structure. Each of the two U-shaped groove plates is provided with a rotating structure that allows each set of telescopic plates to move. Triangular arc blocks are intermittently connected to the outer wall of one side of the top of each of the two U-shaped groove plates, and suction cup rods are fixedly connected to the top of each of the two triangular arc blocks. The two U-shaped groove plates indirectly holding the lamp tube can be limited by the two suction cup rods. An upward structure is provided on one side of each of the two triangular arc blocks to assist the suction cup rods in moving upwards and adhering to the wall surface.

[0009] Preferably, each of the two sets of elastic telescopic structures includes a groove opened on the top end of the telescopic plate, the inner wall of the groove and the outer wall of the arc-shaped convex rubber plate can be slidably connected, and two springs are fixedly connected between the inner wall of one end of the groove and the outer wall of one end of the arc-shaped convex rubber plate.

[0010] Preferably, the rotating structure includes screws movably sleeved in the inner walls of the two ends of the slot plate frame. Both screws are threadedly connected to the two sets of telescopic plates near the bottom. A synchronous belt is fixedly connected between one side of the two screws. A handwheel is fixedly connected to one end of one of the screws. Both screws are specifically composed of two opposite threaded rods.

[0011] Preferably, a vertical plate is fixedly connected to one side wall of the telescopic plate, and the bottom outer wall of the vertical plate and the top outer wall of the U-shaped groove plate are slidably connected, and a rectangular groove is formed on the bottom end of the vertical plate.

[0012] Preferably, a stop plate is intermittently slidably connected in the middle of the rectangular groove, a fixed shaft is fixedly connected in the stop plate, and multiple L-shaped ball-locking rods are fixedly connected on the outer wall of one side of the top of the stop plate. Each L-shaped ball-locking rod can intermittently and tightly engage with the inner wall of one end of the rectangular groove.

[0013] Preferably, each L-shaped cue stick is specifically composed of two sections made of different materials: the cue body is made of metal, and the ball body is made of natural rubber.

[0014] Preferably, a second spring is fixedly connected to the outer wall of one side of the bottom end of the abutment plate, and the bottom end of the second spring is fixedly connected to the inner wall of the bottom end of the rectangular groove.

[0015] Preferably, each of the two top structures includes an inclined groove plate that is slidably connected to one end of the outer wall of the vertical plate. A pressure plate is slidably connected through one side of the top of the inclined groove plate. The bottom end of the pressure plate is hinged to the other side of the top of the pressure plate. Both ends of the fixed shaft are rotatably connected to the inner walls of one end of the inclined groove plate.

[0016] Preferably, the bottom end of the inclined groove plate and the outer wall of one side of the top end of the U-shaped groove plate are fitted and slidably connected, and the top inclined surface of the inclined groove plate can be intermittently fitted and slidably connected with the bottom end of the triangular arc block.

[0017] Preferably, a bending block plate is slidably connected to the body of the suction cup rod, one end of the bending block plate is fixedly connected to the outer wall of one end of the U-shaped groove plate, and the bottom outer wall of the triangular arc block and the top outer wall of the pressure plate can be intermittently fitted together.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention involves manually holding the slotted plate frame and rotating a handwheel to drive one of the screws to rotate. While one screw is rotating, it drives the other screw to rotate synchronously via a timing belt. As a result, the screws with opposite threads rotate, causing a set of telescopic plates inside the U-shaped slot to move in opposite directions until the arc-shaped convex rubber plates on the two telescopic plates can clamp and limit the lamp body. The arc-shaped convex rubber plates made of natural rubber can increase the clamping friction with the surface of the lamp body while avoiding the possibility of pinching and damaging its surface.

[0020] This invention involves rotating the entire device 180 degrees using a handheld slotted plate frame, so that the clamped lamp body faces upwards. Immediately afterwards, the handwheel is rotated again, causing the triangular arc block to make smooth contact with the pressure plate on the inclined slotted plate over a short distance. This causes the pressure plate to move downwards, tilting around a fixed axis. The tilted pressure plate then causes multiple L-shaped ball clamps to disengage from the inner wall of the vertical plate, making it impossible to limit the pressure plate and the inclined slotted plate. Immediately, the unloaded springs automatically reset, indirectly causing the inclined slotted plate to move upwards. The upward-moving inclined slotted plate then causes the suction cup rod to move upwards to a certain height, allowing the suction cup rod to adhere to the side wall where the lamp body is installed. This facilitates the installation of the lamp body by the installer and also limits the lamp body, preventing damage to the lamp body due to gravity shift caused by manual operation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 8As shown, the present invention provides a lamp tube gripping and mounting mechanism, including two U-shaped groove plates 1, two groove plate frames 11 fixedly connected between the two U-shaped groove plates 1, a set of telescopic plates 15 symmetrically and slidably connected to the inner walls of the two U-shaped groove plates 1, and arc-shaped convex rubber plates 17 symmetrically provided on the top end of each of the two sets of telescopic plates 15. The lamp tube body 3 can be intermittently and tightly connected between the inner walls of one end of the two sets of arc-shaped convex rubber plates 17, and each of the two sets of telescopic plates 15 is also provided with an elastic telescopic joint. The structure includes two U-shaped groove plates 1, each with a rotating structure that allows each set of telescopic plates 15 to move. Triangular arc blocks 127 are intermittently attached to the outer wall of one side of the top of each of the two U-shaped groove plates 1. Suction cup rods 128 are fixedly connected to the top of each of the two triangular arc blocks 127. The two U-shaped groove plates 1 that indirectly hold the lamp tube can be limited by the two suction cup rods 128. One side of each of the two triangular arc blocks 127 is provided with an upper top structure to assist the suction cup rods 128 in moving upward and adhering to the wall.

[0033] Both sets of elastic telescopic structures include a plate groove 16 opened on the top end of the telescopic plate 15. The inner wall of the plate groove 16 and the outer wall of the arc-shaped convex rubber plate 17 can be slidably connected. Two springs 18 are fixedly connected between the inner wall of one end of the plate groove 16 and the outer wall of one end of the arc-shaped convex rubber plate 17.

[0034] Using the above scheme: a set of telescopic plates 15 move in opposite directions until the arc-shaped convex rubber plates 17 on the two telescopic plates 15 can clamp and limit the lamp tube body 3. The arc-shaped convex rubber plates 17 made of natural rubber can increase the clamping friction with the surface of the lamp tube body 3, while avoiding the possibility of pinching damage to its surface.

[0035] The rotating structure includes screws 12 that are movably sleeved in the inner walls of the two ends of the two slotted plate frames 11. Both screws 12 are threadedly connected to the two sets of telescopic plates 15 near the bottom. A synchronous belt 13 is fixedly connected between the two screws 12 on one side. A handwheel 14 is fixedly connected to one end of one of the screws 12. Both screws 12 are specifically composed of two opposite threaded rods. A vertical plate 19 is fixedly connected to one side wall of the telescopic plate 15. The bottom outer wall of the vertical plate 19 is slidably connected to the top outer wall of the U-shaped slotted plate 1. A rectangular groove 120 is opened on the bottom end of the vertical plate 19.

[0036] Using the above scheme: the manual hand holds the slot plate frame 11 and then rotates the handwheel 14 to drive one of the screws 12 to rotate. While one screw 12 is rotating, it will drive the other screw 12 to rotate synchronously through the synchronous belt 13. Thus, the screws 12 with opposite threads will drive a set of telescopic plates 15 in the U-shaped slot plate 1 to translate in opposite directions during the rotation process. During the movement of the telescopic plates 15, the vertical plate 19 will also be translated synchronously.

[0037] A stop plate 121 is intermittently slidably connected to the middle of the rectangular groove 120. A fixed shaft 122 is fixedly connected to the stop plate 121. Multiple L-shaped ball-locking rods 123 are fixedly connected to the outer wall of one side of the top of the stop plate 121. Each L-shaped ball-locking rod 123 can intermittently and tightly engage with the inner wall of one end of the rectangular groove 120. Each L-shaped ball-locking rod 123 is specifically composed of two sections of different materials: the rod part is made of metal and the ball part is made of natural rubber. A spring 124 is fixedly connected to the outer wall of one side of the bottom end of the stop plate 121. The bottom end of the spring 124 is fixedly connected to the inner wall of the bottom end of the rectangular groove 120.

[0038] Using the above scheme: the abutment plate 121 is tilted with the fixed axis 122 as the axis point. The tilted abutment plate 121 can drive multiple L-shaped ball clamping rods 123 to disengage from the inner wall of the vertical plate 19, and can no longer limit the abutment plate 121 and the inclined groove plate 125. At the same time, it is also impossible to squeeze the limiting spring 124. The spring 124, which is no longer under force, will automatically reset.

[0039] Each of the two top structures includes a sloping groove plate 125 that is slidably connected to one end of the outer wall of the vertical plate 19. A pressure plate 126 is slidably connected through one side of the top of the sloping groove plate 125. The bottom end of the pressure plate 126 is hinged to the other side of the top of the abutment plate 121. Both ends of the fixed shaft 122 are rotatably connected to the inner walls of one side of the sloping groove plate 125. The bottom end of the sloping groove plate 125 is slidably connected to the outer wall of one side of the top of the U-shaped groove plate 1. The top sloping surface of the sloping groove plate 125 can be intermittently slidably connected to the bottom end of the triangular arc block 127. A bent block plate 129 is slidably connected to the body of the suction cup rod 128. One end of the bent block plate 129 is fixedly connected to the outer wall of one end of the U-shaped groove plate 1. The bottom outer wall of the triangular arc block 127 and the top outer wall of the pressure plate 126 can be intermittently slidably connected.

[0040] Using the above scheme: The vertical plate 19 pushes the inclined slot plate 125 to move horizontally on the slot plate frame 11. In the horizontal position, the inclined slot plate 125 will contact the triangular arc block 127, causing it to move upward according to its own inclined surface. This synchronously drives the suction cup rod 128 to move upward until the triangular arc block 127 moves to the highest point on the inclined slot plate 125. At this time, the suction cup rod 128 is also on the same horizontal line as the lamp tube body 3 that is being gradually clamped. Then, the handwheel 14 is rotated again so that the triangular arc block 127 can make a short distance on the inclined slot plate 125 for smooth movement. At this time, the horizontal movement will also cause the telescopic plate 15 to be stressed. When the lamp tube body 3 is moved and subjected to force, it will push against the spring 18 in the slot 16. This avoids the possibility of the lamp tube body 3 cracking due to continuous pressure without affecting the translation of the inclined slot plate 125. When the triangular arc block 127 is passively smoothed on the inclined slot plate 125, it will contact and squeeze the pressure plate 126. When the spring 124 is no longer subjected to force, it will automatically reset, indirectly driving the inclined slot plate 125 to move upward. The upward-moving inclined slot plate 125 will eventually drive the suction rod 128 to move upward to a certain height. Thus, the suction rod 128 can be attached to the side wall where the lamp tube is installed, making it convenient for the installer to install the lamp tube.

[0041] One point that needs to be added is that when clamping and limiting the lamp tube body 3, the lamp tube body 3 needs to be placed parallel to the ground, with the curved convex rubber plate 17 facing downwards. This facilitates manual activation of the entire device to clamp the lamp tube body 3. After the lamp tube body 3 is clamped and limited, the device can be manually rotated 180 degrees so that the curved convex rubber plate 17 faces upwards. This facilitates subsequent fixing of the entire device to the ceiling using the suction cup rod 128, which is beneficial for the subsequent installation of the lamp tube body 3. Figure 1 As shown, the entire device is currently in a non-operational state, so the two sets of curved convex rubber plates 17 are facing upwards and unfolded, and do not have the capability to... Figure 1 The lamp body 3, which is suspended in the air, is clamped.

[0042] The working principle and usage process of this invention are as follows: A person manually holds the slot plate frame 11 and rotates the handwheel 14 to drive one of the screws 12 to rotate. Simultaneously, the rotation of one screw 12 drives the other screw 12 to rotate synchronously via the timing belt 13. Thus, the screws 12 with opposite threads rotate, causing a set of telescopic plates 15 within the U-shaped slot plate 1 to translate along opposite paths until the arc-shaped convex rubber plates 17 on the two telescopic plates 15 can clamp and limit the position of the lamp tube body 3 placed on the ground. Then, the entire device is manually rotated 180 degrees, allowing the arc-shaped convex rubber plates 17 made of natural rubber to further clamp the surface of the lamp tube body 3. While applying friction, it also avoids the possibility of pinching the surface. Simultaneously, as the telescopic plate 15 moves, it also drives the vertical plate 19 to move horizontally. This vertical plate 19 then pushes the inclined slot plate 125 to move horizontally on the slot plate frame 11. During this horizontal movement, the inclined slot plate 125 contacts the triangular arc block 127, causing it to move upwards according to its inclined surface. This, in turn, drives the suction cup rod 128 upwards until the triangular arc block 127 reaches its highest point on the inclined slot plate 125. At this point, the suction cup rod 128 is also on the same horizontal line as the gradually clamped lamp tube body 3. At this point, the operator needs to pause rotating the handwheel 14 and then hold the handwheel... The slot plate frame 11 rotates the entire equipment 180 degrees so that the clamped lamp body 3 faces upward. Then, the handwheel 14 is rotated again so that the triangular arc block 127 can slide smoothly on the inclined slot plate 125 for a short distance. At this time, the translation will cause the telescopic plate 15 to move under force. Instantly, the lamp body 3 under force will push against the spring 18 in the slot 16. Thus, without affecting the translation of the inclined slot plate 125, it can also avoid the possibility of continuous pressure on the lamp body 3 causing it to crack. When the triangular arc block 127 is passively smoothing on the inclined slot plate 125, it will contact and squeeze the pressure plate 126, causing it to move downward and drive the abutment plate 121 to advance around the fixed axis 122. When the plate is tilted, the tilted abutment 121 can cause multiple L-shaped ball clamps 123 to disengage from the inner wall of the vertical plate 19, making it impossible to limit the abutment 121 and the inclined groove plate 125. In the same way, it can no longer limit the compression limiting spring 124. The spring 124, which is no longer under force, will automatically reset, indirectly causing the inclined groove plate 125 to move upward. The upward-moving inclined groove plate 125 will eventually cause the suction cup rod 128 to move upward to a certain height. Thus, the suction cup rod 128 can be attached to the side wall where the lamp tube is installed, which is convenient for the installer to install the lamp tube body 3. At the same time, it can also limit the lamp tube body 3 to avoid gravity displacement caused by manual operation, which could lead to damage to the lamp body.
