Abstract

A tool is used for placing or removing light bulb on high and the manufacturing and the using of the tool. The utility model refers to a tool for avoiding the climbing operation and implementing the placing and the removing of the light bulb on high. The tool for placing or removing light bulb on high is implemented by that a locking device, a clamping device, a winding device and a light electric torch [14]are respectively arranged on two telescopic tubes [1][3]sheathed together. A hand wheel [15] and a line wheel [17]are rotated to drive line cords [2][11]to move downward and to cause an arm [9]to be healed; the arm [9] drives a gripper [12]to implement grasping the light bulb. The tool for placing or removing light bulb on high is used for placing and removing various light bulbs having no closed bulb covers and fixed on bulb heads. Using the tool for placing or removing light bulb on high is safe, convenient and quick; the tool for placing or removing light bulb on high can separately operate at all hours of the day or night.

Description

Tool for placing or removing light bulb on high

The utility model is the instrument that is used to load and unload the eminence lighting bulb.

The method of existing loading and unloading eminence lighting bulb all steps down on the desktop or on the ladder and directly carries out with hand, and this method is dangerous, also is not easy to independence and night work.

Task of the present utility model is to propose a kind of ascend operation of avoiding, and implements the instrument of loading and unloading eminence lighting bulb.

Action when the utility model is imitation hand cargo lamp bubble, finish as follows: when rotating handwheel, the spline on the axle can drive the rotation of line wheel, and the cotton rope on the line wheel will haul arm closes up it, firmly grasps lighting bulb up to handgrip.

Below in conjunction with accompanying drawing utility model is further described.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.Fig. 2 is the profile at Figure 1A A place.Fig. 3 is the profile at Figure 1B B place.

Telescoping tube ［ 3 ］ with certain-length, be sleeved in another telescoping tube with certain-length ［ 1 ］, the fixing of the relative axial position between two telescoping tubes finished by locking device, and it is achieved in that the upper end in telescoping tube ［ 1 ］, be fixed with clamp ring ［ 4 ］, be provided with taper hole in it, interior dress tapered sleeve ［ 6 ］, axial at tapered sleeve ［ 6 ］, be provided with two groups of grooves, every group of groove is more than 3 and be staggered, and wherein an end of one group of groove communicates with small end, and end of another group groove communicates with holding greatly.Clamp ring ［ 4 ］ is threaded with clamp ring ［ 5 ］.When clamp ring ［ 5 ］ is rotated, promote tapered sleeve ［ 6 ］ and move axially, in clamp ring ［ 4 ］, produce the purpose that strain reaches locking telescoping tube ［ 3 ］ by tapered sleeve ［ 6 ］.

The bared end of telescoping tube ［ 3 ］ is provided with clamping device, and it is to realize like this; Be fixed on the power frame ［ 20 ］ on flexible ［ 3 ］, be provided with in groups axle ［ 7 ］, torsion spring ［ 8 ］, arm ［ 9 ］, arm ［ 9 ］ is provided with handgrip 12 ］, cotton rope ［ 11 ］, being shaped as of handgrip ［ 12 ］ has flange, the sphere of diameter between 40 millimeters to 70 millimeters, lining ［ 13 ］ is fixed in the sphere, and its material is the moderate sponge of elasticity.Arm ［ 9 ］ can be in all the time around axle ［ 7 ］ swing and under torsion spring ［ 8 ］ effect and close up state.Cotton rope ［ 11 ］ other end is by being contained in conductor cap ［ 10 ］ on the telescoping tube ［ 3 ］, being tied with of cotton rope ［ 2 ］, and the other end of cotton rope ［ 2 ］ ties up to line by axle ［ 18 ］ and takes turns on ［ 17 ］.

The lower end of telescoping tube ［ 1 ］ is provided with Winder.It is to realize like this; Be fixed on the framework ［ 19 ］ on the telescoping tube ［ 1 ］, axle ［ 16 ］, line wheel ［ 17 ］ are housed, the hole of framework ［ 19 ］ and line wheel ［ 17 ］ be all splined hole and with axle ［ 16 ］ on spline fitted, spline is divided into two sections, after handwheel ［ 15 ］ pushes, two sections splines should be able to mesh with framework ［ 19 ］ upper spline hole simultaneously, otherwise should break away from.

When rotating handwheel ［ 15 ］, line wheel ［ 17 ］ and then rotates, and the cotton rope on it ［ 2 ］ drives cotton rope ［ 11 ］ closes up arm ［ 9 ］.

Illumination torch ［ 14 ］ is contained in arm ［ 9 ］ middle part, the two connects for elasticity, promptly on the shell of illumination torch ［ 14 ］, be provided with two arms, with arm ［ 9 ］ tight fit, two facies medialis brachiis middle part is respectively established a round boss and is matched with the hole at arm ［ 9 ］ middle part, be provided with end tooth around the round boss, a bar shaped boss is respectively established in arm ［ 9 ］ mider hole both sides, and end tooth matches with the bar shaped boss.

Use method of the present utility model to divide following step:

1. handwheel ［ 15 ］ is pulled out.

2. unclamp clamp ring ［ 5 ］, adjust the length and the locking of telescoping tube ［ 3 ］.

3. open illumination torch ［ 14 ］, adjust illumination angle.

4. lift telescoping tube ［ 1 ］ the flange contact illumination bulb of handgrip ［ 12 ］ is also upwards pushed away, lighting bulb is entered in the lining ［ 13 ］.

5. rotate handwheel ［ 15 ］, make spline engagement.

6. rotary extension pipe ［ 1 ］ unloads lighting bulb.

During the dress lighting bulb, in the lining ［ 13 ］ of at first lighting bulb must being packed into, the step in the time of can repeating to unload lighting bulb then.

Use the utility model, be regardless of night on daytime, a people stands in the operation that can implement to load and unload the eminence lighting bulb on the ground.

Implementing best way of the present utility model, is the big soft material of one deck frictional resistance to be set on lining ［ 13 ］ and to adopt the multiple-segment telescopic tube suit.
