Description

Technical Field

[0001] The present invention relates to the technical field of manual tools, and in particular, to a tool and method for installing and removing a fluorescent tube. Background Art

[0002] Fluorescent tubes are generally used in places such as factories, classrooms, offices, and workshops. To ensure the lighting quality, the fluorescent tubes need to be replaced regularly; the installation positions of the fluorescent tubes in such places are generally relatively high, and it is necessary to use a ladder or a table to raise the height and then install them manually, which poses a risk of falling from a height. At the same time, the manual climbing installation is inconvenient, consuming both manpower and time. The hanging heights of the fluorescent tubes in places such as classrooms and workshops are not the same, which increases the complexity of the installation and removal process.

[0003] Currently, there is no manual device for automatically replacing fluorescent tubes. Relevant research has been carried out to solve this problem, and a tool for installing and removing a fluorescent tube needs to be designed. Summary of the Invention

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. At present, when installing and disassembling fluorescent tubes in places such as classrooms and workshops, most rely on items such as ladders and desks and chairs to pad up, and people climb to high places for installation and disassembly and replacement. In the absence of the assistance of others, padding up and climbing are rather troublesome and prone to falling accidents.

[0033] 3. The present invention is a manual tool with a simple structure, low cost, small volume, and easy to carry.

[0034] 4. The present invention adopts a link mechanism at the clamping end to realize the clamping movement. The clamping of the upper and lower clamping jaws on the tube can be achieved through the simple movement of the front and back telescoping of the rod, and the link mechanism can ensure that the clamping force will not be too large to damage the tube.

[0035] 5. The telescoping mechanism of the present invention adopts a smooth rod and a locking nut, so the stepless adjustment of the tool length can be realized, which can be completed by rotating the nut, and the operation is convenient.

[0036] 6. The present invention is equipped with a tensioning mechanism at the handle, so the tension of the transmission wire can be controlled through the tensioning mechanism, enabling the metal wire inside the present invention to be tensioned at various lengths, thereby transmitting motion.

[0037] 7. The present invention combines the clamping mechanism and the rotating mechanism entirely at the clamping jaw, without redundant structures, and can be well docked with the tube connector to ensure the working quality.

[0038] Based on the above reasons, the present invention can be widely promoted in the fields of installation and disassembly of fluorescent tubes, etc. Description of the Drawings

[0055] The present invention provides a tool for installing and disassembling a fluorescent tube, which is a tool for installing and disassembling a fluorescent tube used for lighting in indoor office places such as factories and classrooms, and can realize the convenient installation and disassembly of the fluorescent tube, and achieve the rapid installation and replacement of the fluorescent tube.

[0056] A tool for installing and disassembling a fluorescent tube according to the present invention includes a handle 2, a device housing 𝟏𝟎, a clamping part, a rotating part, a transmission part, a telescopic part, a tensioning part, and a driving part. The clamping part is installed on the front side of the device housing 𝟏𝟎 and is responsible for clamping the fluorescent tube; the rotating part is installed on the device housing 𝟏𝟎 and is responsible for rotating the fluorescent tube after it is clamped in place, so as to fix the fluorescent tube at the tube joint; the telescopic part is fixedly connected between the rear side of the device housing 𝟏𝟎 and the handle 2 and has a telescopic function, and is responsible for adjusting and fixing the length of the entire installation and disassembly tool, so that fluorescent tubes of different heights can be disassembled; the tensioning part is installed on the handle 2 and is connected to a wire, and is responsible for ensuring the tension of the transmission wire when the telescopic part adjusts the length of the device, so that the device can achieve movement through the transmission part at different lengths; the driving part is installed on the handle 2 and is connected to the rotating part and the clamping part through a wire, and is responsible for controlling the driving of the movement of the rotating part and the clamping part. The present invention can realize the installation and disassembly of fluorescent tubes at different heights and in different environments, and has a simple overall structure, a small volume, convenient operation and safety.

[0057] Such as Figure 1As shown in the figure, a disassembly and assembly tool for a fluorescent tube of the present invention includes a driving pressure handle 1, a handle 2, a wire pressing gasket 3, a rotary adjustment wheel handle 4, a rotary adjustment knob 5, an outer telescopic rod 6, a locking nut 7, a locking nut housing 8, an inner telescopic rod 9, a device housing 10, and a tube clamping jaw 11.

[0058] As Figure 2 shown, the telescopic part includes an inner telescopic rod 9, an outer telescopic rod 6, a locking nut 7, and a locking nut housing 8. The locking nut 7 is installed at one end of the outer telescopic rod 6 by interference fit. One end of the inner telescopic rod 9 passes through the locking nut 7 and is inserted into the outer telescopic rod 6 (inserted into the hollow part of the outer telescopic rod 6). The outer part of the inner telescopic rod 9 is sleeved with a locking nut housing 8. After passing through the inner telescopic rod 9, the locking nut housing 8 is threadedly engaged with the external thread of the locking nut 7. The other end of the outer telescopic rod 6 is connected to the handle 2 by interference fit. The protruding end of the inner telescopic rod 9 is fixedly connected to the mounting hole at the rear side of the device housing 10 by interference fit; by loosening the locking nut 7, stepless adjustment of the length of the inner and outer telescopic rods can be achieved. After tightening the locking nut 7, the inner telescopic rod 9 will be fixed due to the pressing force of the nut. When the locking nut housing 8 rotates forward, the locking nut 7 presses the inner telescopic rod 9, thereby fixing the length of the telescopic part. When the locking nut housing 8 rotates in reverse, the locking nut 7 is loosened and the frictional force is reduced, ensuring that the inner telescopic rod 9 can move freely axially, thus achieving stepless adjustment of the device length.

[0059] As Figure 3As shown, the clamping part includes two groups of lamp tube grippers 11 which are installed on the device housing 10 and arranged at intervals. Each group of lamp tube grippers 11 includes two lamp tube grippers 12 with chutes, pins 19, two curved rods 15, two long straight rods 16, two short straight rods 17 and a T-shaped rod 18.

The middle part of the curved rod 15 is connected to the device housing 10 through a pin 19. The other end of the curved rod 15 is connected to one end of the short straight rod 17 through a pin 19, and the other end of the short straight rod 17 is connected to the T-shaped rod 18 through a pin 19. The lamp tube grippers 12 with chutes on both sides and the linkages (curved rods 15, long straight rods 16, short straight rods 17) on both sides are symmetrically arranged. The T-shaped rod 18 passes through the through hole at the rear of the position on the device housing 10 where the clamping part is installed. Finally, by pulling the T-shaped rod 18 back and forth, the lamp tube grippers 12 with chutes can move up and down, thereby realizing the clamping action. In this embodiment, the curved rod 15 includes a first rod and a second rod. One end of the first rod is connected to the lamp tube gripper 12 with a chute, and the other end is connected to one end of the second rod. The other end of the second rod is connected to the short straight rod 17.

A rotating cushion block 13 is installed in the arc-shaped chute at the clamping position of each lamp tube jaw 12 with a chute. The upper rotating cushion block 13 is pressed and fitted against the front side of the lamp tube jaw 12 with a chute by a return compression spring 14 to ensure that the rotating cushion block 13 is subjected to a forward thrust. The rear sides of the upper rotating cushion blocks 13 of each group of lamp tube jaws 11 are connected and tightened with a first wire. The first wire sequentially passes through the T-shaped rods 18 of this group and the through holes on the device housing 10 at the rear side of the T-shaped rods 18 along the clamping part, bypasses a guide wheel 21 directly behind this group, and is wound around the upper side of the wire reel 23.

The tensioning part is installed inside the housing of the handle 2, and the housing of the handle 2 includes a left handle housing 25 and a right handle housing 24 that are fixedly connected by fastening. The tensioning part includes a tensioning wheel 28, a tensioning wheel end cover 27, a clockwork spring 26 and a wire pressing gasket 3. One part of the tensioning part is that two tensioning wheels 28 are respectively fitted on two first shafts on the inner wall of the left handle housing 25. The first shaft is located inside the tensioning wheel 28. The clockwork spring 26 is fixed inside the tensioning wheel 28. The clockwork spring 26 is sleeved outside the first shaft, and the innermost side (the end of the innermost circle) of the clockwork spring 26 is fixedly connected in the gap on the first shaft of the left handle housing 25. The outermost end of the clockwork spring 26 is fixedly connected to the inner wall of the tensioning wheel 28. The end of the open side of the tensioning wheel 28 is fixedly connected with a tensioning wheel end cover 27 by interference fit. The tensioning wheel end cover 27 fits with one end of the open part of the tensioning wheel 28, and the clockwork spring 26 is encapsulated inside the tensioning wheel 28 through the tensioning wheel end cover 27. Wires are wound around both tensioning wheels 28 and are fitted according to the first shafts on the inner wall of the left handle housing 25. The other part of the tensioning part is a wire pressing gasket 3 installed on the groove of the left handle housing 25. The wire pressing gasket 3 is fitted with the grooves opened on the upper edges of the left handle housing 25 and the right handle housing 24. When the two handle housings are closed, the wire pressing gasket 3 can move along the grooves on the left handle housing 25 and the right handle housing 24. The wire bypasses the boss on the inner wall of the left handle housing 25, and the moving wire pressing gasket 3 can contact the boss to realize the pressing and fixing of the wire bypassing the boss. The driving part includes a driving press handle 1, a clamping part guide wheel 29, a rotary adjusting wheel 30, a rotary adjusting wheel shaft 31, a rotary adjusting knob 5, a rotary adjusting handle 4, and a second wire and a third wire for transmission.

At the device housing 10, it is divided into two wires and respectively passes around the two guide pulleys 21 at the device housing 10. The two wires are finally tied to the holes of the two groups of T-shaped rods 18. After the wire pressing gasket 3 presses the third wire, by pulling the driving pressure handle 1, the third wire can be stretched, thereby realizing the clamping movement of the clamping part and clamping the fluorescent tube.

[0063] As Figure 6 Fig. is the layout diagram of the transmission wires for the rotating part and the clamping part. One end of the wire for the clamping part is tied to the free end of the T-shaped rod 18, extends backward around the guide pulley 21, and the other clamping jaws are symmetrically arranged. Finally, the two wires are combined into one behind the wire release wheel 23 and pass through the telescopic part. One end of the wire for the rotating part is connected to the upper rotation pad 13, passes through the hollow part of the return compression spring 14, passes out through the hole at the rear side of the position where the lamp tube clamping jaw 11 is fixed on the device housing 10, passes around the guide pulley 21, winds around the upper side of the wire release wheel 23, then passes through the hole on the side of the wire release wheel 23 and winds out on the lower side of the wire release wheel 23, passes around the guide pulley 21, passes through the hole on the device housing 10, and is connected to one end of the rotation pad 13 on the other lamp tube clamping jaw 12 with a chute. The wires on the other lamp tube clamping jaw 11 are symmetrically arranged.

[0064] As Figure 7 Fig. is the layout diagram of the transmission wires for the driving part and the tensioning part. The two wires are respectively wound out from the tension pulley 28 and first pass around the boss on the inner wall of the upper handle housing 25. The wire for controlling the clamping passes around the boss and then winds backward around the clamping part guide pulley 29, is led out from the hole of the driving pressure handle 1 at the rear side, passes through the telescopic part, and is divided into two wires at the device housing 10. The wire for controlling the rotation winds around the rotation adjustment wheel 30 for several turns, then passes through the telescopic part to reach the wire release wheel 23 on the device housing 10, winds around the middle part of the wire release wheel and is finally tied to the hole.

[0065] The working principle of the present invention:

[0066] The tensioning wheel 28 realizes the retraction and extension of the two strands of metal wire used for control. In order to ensure that the metal wire can be tensioned to ensure transmission when the length of the telescopic part is adjusted, a spring 26 is fixed in the tensioning wheel 28 and is fixed in the gap of the tensioning wheel shaft after it rotates a few weeks. When it is necessary to complete the drive and control through the metal wire, the metal wire is pressed against the gasket 3 to complete the fixation of the end of the metal wire; when the driving pressure handle 1 is pulled, the clamped metal wire is pulled back to allow the lamp tube clamp 11 to realize the clamping movement, and the rotating adjustment wheel 30 is rotated to control the retraction and extension of the metal wire, driving the rotation of the wire-releasing wheel 23, and finally controlling the equal stroke retraction and extension of the rotating part of the metal wire between the upper and lower lamp tube clamps 12 with slide grooves.

[0067] The present invention also provides a method for assembling and disassembling a fluorescent tube assembly and disassembly tool, comprising the following steps:

[0068] S1. Before replacing the fluorescent tube, loosen the locking nut 7, adjust the length of the telescopic part according to the height of the fluorescent tube, and then tighten the locking nut 7;

[0069] S2, tighten the wire compression gasket 3 upwards to put the transmission part in a tensioned state;

[0070] S3. Hold the handle 2 and lift the entire assembly and disassembly tool to the lamp tube joint. Pull the driving handle 1 and hold it to achieve the clamping part clamping the fluorescent lamp tube.

[0071] S4. After clamping the fluorescent tube, turn the rotary adjustment wheel handle 4 on the rotary adjustment knob 5, and the rotating part starts to move, realizing a 90° rotation of the old fluorescent tube;

[0072] S5. Remove the old fluorescent tube, place the new fluorescent tube between the two tube clamps 11, and pull the driving handle 1 to clamp it;
