Description

Technical Field

[0001] The utility model relates to the technical field of hand tools, in particular to a replacement mechanism for replacing light bulbs. Background Art

[0002] Hand tools, also known as manual tools, are tools that are used by hand to turn or apply force to the tools, as opposed to power tools. Light bulb replacement tools are common hand tools. They feature a multi-section telescopic rod that can be adjusted in length to reach bulbs at high altitudes or in hard-to-reach locations. Lighting tools or suction cups can greatly simplify the process of replacing bulbs in high altitudes or in hard-to-reach locations.

[0003] In the prior art, a suction cup is usually used to hold the glass bulb of the light bulb, and then the screw thread of the light bulb is aligned with the lamp holder through a telescopic rod, and the telescopic rod is rotated to install it. After the installation is completed, the suction cup is removed. Since the suction cup holds the glass bulb based on the principle of air pressure, it is impossible to manually operate it to allow air to enter the suction cup when removing it. Therefore, the suction cup will always generate suction. Direct pulling may cause damage to the lamp holder, and in severe cases, the light bulb may fall, thereby greatly reducing the safety of light bulb installation.

[0004] Therefore, there is an urgent need to improve the replacement mechanism for replacing light bulbs to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a replacement mechanism for replacing light bulbs, which is fixed by a steel wire and a pull ring. After the light bulb is installed, the steel wire can be pulled to drive the pull ring to slide down, and the pull ring drives one side of the suction cup to slide downward, thereby causing the suction cup to deform. Air enters between the glass bulb and the suction cup from one side of the pull ring, so that the light bulb and the suction cup are separated, and the adsorption force can be easily eliminated. This not only prevents the lamp holder from being pulled and damaged, but also greatly reduces the probability of the light bulb falling, thereby greatly improving the safety of light bulb replacement.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0007] A replacement mechanism for replacing light bulbs includes a shell and a suction cup fixedly mounted on the shell, a pull ring fixedly provided on one side of the suction cup, a steel wire tied and fixed to the pull ring, a roller rotatably provided inside the shell, the steel wire extends into the interior of the shell and contacts the side of the roller, a connector is clamped on the end of the shell away from the pull ring, and the steel wire passes through the shell and the connector and extends to the outside of the connector.

[0008] Preferably, a mounting hole is provided at the upper end of the shell, and the suction cup is fixedly arranged inside the mounting hole.

[0009] Preferably, a cross bolt is rotatably provided on the mounting hole, the cross bolt passes through the suction cup and the mounting hole and extends to the inner side of the shell, and the bottom side of the cross bolt abuts against the inner side of the suction cup.

[0010] Preferably, a notch is fixedly provided at one end of the shell close to the connector, an inner slide groove is provided on one side of the notch, and a depression is provided at one end of the inner slide groove away from the notch.

[0011] Preferably, a spring piece is fixedly provided on the connector, and a protrusion is fixedly installed on one end of the spring piece away from the connector, and the protrusion corresponds to the recess.

[0012] Preferably, a plurality of evenly distributed rivets are fixedly provided inside the shell.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. The utility model is fixed by a steel wire and a pull ring. After the bulb is installed, the steel wire can be pulled to drive the pull ring to slide down. The pull ring drives one side of the suction cup to slide downward, thereby deforming the suction cup. Air enters between the glass bulb and the suction cup from the side of the pull ring, so that the bulb and the suction cup are separated, and the adsorption force can be easily eliminated. It can not only prevent the lamp holder from being pulled and damaged, but also greatly reduce the probability of the bulb falling, thereby greatly improving the safety of bulb replacement.
