A straight tube fluorescent lamp replacement device

Abstract

The present invention discloses a replacement device for a straight tubular fluorescent lamp, which comprises a fixing rod. A lamp tube clamp, a rotating head and a rotating seat are installed at the top end of the fixing rod. A rotating handle is installed in the middle of the fixing rod. A handle and a rotating knob are installed at the bottom end of the fixing rod. The rotating handle is connected to the fixing rod by a thread. Rotating the rotating handle drives a steel wire rope to pull the lamp tube clamp to clamp the lamp tube. The threaded connection enables the lamp tube clamp to be in a clamping state all the time. The rotating knob drives the steel wire rope to pull the rotating head to rotate through a handle push rod and a right-angle part, so as to remove the lamp tube. The threaded connection design of the rotating handle and the fixing rod can maintain the magnitude of the clamping force after clamping the lamp tube, preventing the accidental detachment of the lamp tube during operation. The present invention is mainly designed for the lamp tube of a straight tubular fluorescent lamp, and has the advantages of simple structure, light weight, sensitive operation and strong pertinence.

Description

Technical Field

[0001] The present invention relates to a replacement device for straight tubular fluorescent lamps and belongs to the field of daily necessities. Background Art

[0002] In people's living environments, straight tubular fluorescent lamps are used for lighting in the vast majority of places and public areas. Once a fluorescent lamp is damaged, it needs to be replaced. However, usually the fluorescent lamps are installed on the ceiling, and tools such as ladders are often required, which is not only inconvenient but also very dangerous. Therefore, there is an urgent need for a lamp replacement device that can be operated on the ground to meet the needs of people's daily lives. Currently, a variety of bulb replacement devices have emerged on the market, but they are only applicable to bulbs with screw threads or bayonet sockets and are not applicable to straight tubular fluorescent lamps. Therefore, we have made improvements to the above-mentioned devices and designed a replacement device for straight tubular fluorescent lamps for straight tubular fluorescent lamps. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Such as Figure 1 、such as Figure 2 、such as Figure 3 and such as Figure 4As shown in the figure, the present invention provides a straight tubular fluorescent lamp replacement device, which includes a fixed rod 8. A rotating seat 7 is installed at the top of the fixed rod 8. There is a mounting hole at the top of the rotating seat 7, and a rotating head 2 is connected by a precision reamed bolt. One end of the rotating head 2 is connected to the rotating seat 7 through a tension spring 5. There are mounting holes at both ends of the rotating head 2, and two lamp tube clips 1 are connected by precision reamed bolts. A torsion spring 4 is installed between the lamp tube clip 1 and the rotating head 2. A through hole is opened in the middle of the fixed rod 8 for installing a tension pin 9. There is an external thread in the middle of the fixed rod 8, which is connected to the internal thread of a rotating handle 10. There is a rotating groove at the top of the rotating handle 10 for installing the tension pin 9. A handle 11 is installed at the bottom of the fixed rod 8. There are two lugs at the top of the handle 11 for installing a rotating handle 12. A rectangular hole is opened in the upper part of the handle 11 for installing a right-angle part 15. One end of the rotating handle 12 and the right-angle part 15 are connected by two handle push rods 13. The other end of the right-angle part 15 is connected to the other end of the rotating head 2 through a second steel wire rope 6. The tension pin 9 is connected to the two lamp tube clips 1 through a first steel wire rope 3. The clamping part of the lamp tube clip 1 is adhered with soft rubber. Soft rubber is provided on the exteriors of the rotating handle 10, the handle 11, and the rotating handle 12.

[0016] There are two lamp tube clips 1. The clamping part of the lamp tube clip 1 is arc-shaped, and the material of the clamping part of the lamp tube clip 1 is soft rubber. This makes the lamp tube clip 1 fit the surface of the lamp tube better, reduces the pressure on the lamp tube, and reduces the possibility of the lamp tube breaking.

[0017] Soft rubber is sleeved on the surfaces of the handle 11, the rotating handle 10, and the rotating handle 12. This can increase the friction with the hand and reduce the possibility of the device slipping from the hand.

[0018] The lamp tube clip 1 is clamped by the up and down movement of the rotating handle 10, and the rotating handle 10 is connected to the fixed rod 8 by a thread. Since the thread has self-locking property, the lamp tube can be prevented from falling off the lamp tube clip during operation after clamping.

[0019] A torsion spring 4 is installed between the lamp tube clip 1 and the rotating head 2. When it is necessary to take the lamp tube out of the lamp tube clip 1, the torsion spring 4 can reset the two lamp tube clips 1 and open them at a certain angle, simplifying the operation steps.

[0020] A tension spring 5 is installed at one end of the rotating head 2. The maximum rotation angle of the rotating head 2 is 135 degrees. The other end of the rotating head 2 is connected to the right-angle part through the second steel wire rope 6. The lamp tubes used in daily life need to be rotated 90 degrees to be removed. The maximum rotation angle of the rotating head 2 is much larger than the rotation angle required for removing the lamp tube. Therefore, the disassembly process is relatively simple.

[0021] The handle 11 is parallel to the fixed rod 8. The included angle between the rotating handle 12 and the handle 11 is 24.5 degrees. The distance between the farthest ends of the rotating handle 12 and the handle 11 is 80 mm. The distance between the rotating handle 10 and the handle 11 is 26 cm. Such an operating posture and the opening degree of the rotating handle 12 are more ergonomic.

[0022] All materials used in the present invention are 6061 aluminum materials, which greatly reduce the weight compared with stainless steel and make the operation easier.

[0023] When the present invention is in use, first adjust the height to align the lamp tube clamp 1 with the middle part of the lamp tube. Rotate the rotating handle 10 to drive the tension pin 9 to pull the first steel wire rope 3 downward. The first steel wire rope 3 pulls the lamp tube clamp to clamp the lamp tube. Then press the rotating handle 12. The rotating handle 12 drives the right-angle part 15 to rotate through the handle push rod 13. The other end of the right-angle part 15 pulls the second steel wire rope 6 downward. The second steel wire rope 6 pulls the rotating head 2 to rotate around its fulcrum, so as to remove the lamp tube. After the lamp tube is removed, rotate the rotating handle 10 in the opposite direction. The rotating handle 10 drives the tension pin 9 to move upward to relax the steel wire rope. The torsion spring 4 installed on the lamp tube clamp 1 drives the two lamp tube clamps to open, so as to remove the lamp tube.
