Abstract

The utility model discloses a loading and unloading stick for overhead lamp which is composed of a vertical bar, a pull rope, a pulley and a 'U'-shaped clamping slice. The utility model can used for the loading and unloading of overhead lamps of corridors and street lamps. The utility model is a simple and practicable handling tool.

Description

Loading and unloading stick for overhead lamp

The utility model relates to a kind of high-altitude lamp loading bar, and it belongs to the handling instrument field.

Present high-altitude lamp (as the stair of building, corridor, street lamp etc.) loading and unloading all need be used work high above the ground such as ladder, and are promptly inconvenient, also dangerous.For this reason, we have designed a kind of high-altitude lamp loading bar, can overcome above-mentioned deficiency.

The utility model is to realize like this, be subjected to the inspiration of scalable fishing rod, designed a kind of telescopic high-altitude lamp loading bar easy to carry, 4. the strut of two equal length is installed in telescopic montant with identical angle and 2. goes up, and load onto a pulley respectively at the strut two ends, be with a limit wire clips on the pulley, in the tip designs of montant a cross bar 5., a pair of spring is adorned at the center of cross bar, and the other end of spring is fixed on the supporting member of " U " font clamp clip ⑾ and 10. goes up." U " font clamp clip ⑾ is that sheet metal is made.9. the upper end of clamp clip ⑾ has two round little ring fixed tensioning ropes, on the little ring that one end of rope is fixed therein, through being with limit wire clips pulley 7. 6., 3. the pulley of process band slide block limits the pulley of wire clips to be fixed on another round little ring through another again.A stay cord end 1. is fixed on the pulley of band slide block.When finger-tight stay cord 1. the time, slide block drives the tensioned lines action, and " U " type folder is unclamped, and when hand was decontroled stay cord, " U " type folder then clamped.The friction pad of making at rubber of " U " type folder inwall edge or flannelette, loading and unloading bulb that can safety.

Be illustrated with regard to accompanying drawing below:

Accompanying drawing 1 is a high-altitude lamp loading bar schematic diagram.Accompanying drawing 2 is a 2. structural representation of montant.

Be stay cord 1. among the figure, 3. the pulley that is fixed on the band slide block is gone up.2. montant can be made into telescopic, and a cross bar is fixed in its top 5., two springs of cross bar center fixed 8., spring other two ends 8. are separately fixed at supporting member and 10. go up.⑾ be " U " font clamp clip that sheet metal is stamped to form, and studs with the friction pad ⑿ that rubber or flannelette are made in the clamp clip, also fixes a pair of strut symmetrically 4. on the montant, and the pulley that a band limit wire clips is adorned at strut two ends 4. respectively 6..

Bulb is put into " U " font clamp clip earlier, after lifting montant bulb being inserted socket, pull pulley that 1. stay cord drive the band slide block simultaneously 3., make the 6. 9. stressed equalization of tensioned lines on both sides of pulley, " U " font clamp clip opens bulb and promptly installs, and regains montant and gets final product.7. the limit wire clips is for 9. tensioned lines is slided and unlikely coming off.

The utility model is simple in structure, convenient operation. Montant is expansion link 2., is convenient for carrying, and improves work efficiency. If it is then more convenient that our bulb (declaring simultaneously patent) of " safe spring inserting type lamp base and socket " of design is installed.

Claims

1, a kind of high-altitude lamp loading bar that replaces ladder to use is characterized in that;

A: a telescopic montant is arranged 2.;

B: two of strut length, angles 4. must be identical;

C: an extension spring end 8. is fixed on cross bar and 5. goes up; The other end then is separately fixed at the supporting member that steps up sheet ⑾ and 10. goes up;

D: clamp clip ⑾ is " U " font sheet metal;

E: 3. pulley is the pulley of band slide block.

2, according to the 1. described high-altitude lamp loading bar of claim, it is characterized in that being contained in strut 4. the pulley at two the limit wire clips is housed on 7..

3, it is characterized in that according to the 1. described high-altitude lamp loading bar of claim the inboard of " U " font clamp clip ⑾ studs with the friction pad that rubber or flannelette are made.
