Description
Technical field
The utility model relates to a kind of expansion bolt hand-hole booster, belongs to engineering construction service field.
Background technology
At present, in daily life and modernization construction, expansion bolt purposes is very extensive, as: fixing frameless balcony window, burglary-resisting window, water heater, lampblack absorber, furred ceiling screw mandrel, kitchen guarding's assembly etc.Expansion bolt is made up of expansion set and bolt, and its operation principle is: expansion bolt be fixedly utilize tapering to impel expansion bolt produce friction bond stress, reach fixed effect.. there is screw thread bolt one end, and there is tapering one end, and outer bread one irony cylinder, there are some even otch (see figure bis-) irony cylinder one end.They are pounded in hole that wall is accomplished fluently in advance together, and then use spanner nutting, nut pulls outward bolt, is had by bolt one end of tapering to draw in irony cylinder cut ends, and irony cylinder cut ends is by spreading, so expansion bolt is just tightly fixed on the wall.
Expansion bolt hand-hole, the general technique adopted first gets out the hole slightly less than the large footpath of expansion bolt afterbody, then carries out dedusting to hole, then by one end aligning aperture of expansion bolt with tapering, to the expansion bolt end of thread impose brute force pound into.Owing to being subject to powerful external force, the threaded one end of expansion bolt can produce distortion, causes the nut of expansion bolt smooth and easyly can not to be screwed into, to back-out, and causes expansion bolt not have corresponding effect, even scraps.Want double thread crushed element to process, the reclamation activities usually taked has following several:
(1) die handle tapping is again adopted.
(2) crushed element is ground off (this way is extremely conventional, but due to grinding wheel unbalance stress, easily fragmentation, abnormally dangerous) with abrasive machine.
(3) with saw bow, crushed element is amputated.Though (this way is comparatively safe, and the time needed is longer, and sometimes because space is too narrow, this method is also infeasible.）
But no matter adopt which kind of mode to process crushed element, difficulty is all very large, and waste time and energy all very much, some measure also has very high danger.Thus cause that labour intensity is large, extensive work time waste, inefficiency.Sometimes also unnecessary personal injury can be caused.The needs of modern production can not be met.
Summary of the invention
The utility model provides a kind of expansion bolt hand-hole booster, causes the problems such as labour intensity is large, extensive work time waste, inefficiency for solution prior art.
The technical solution of the utility model is: a kind of expansion bolt hand-hole booster, and comprising is threaded twists slip prevention part 3 from latching segment 1, power-assisted cap 2, hand, is threaded from latching segment 1 as being arranged on the blind hole in power-assisted cap 2; Wherein be threaded and carry out thread connection from the internal thread of latching segment 1 and the external screw thread of expansion bolt end, be arranged with hand outside power-assisted cap 2 and twist slip prevention part 3.
Described power-assisted cap 2 and the area of section of expansion bolt abutting end are greater than the area of section of power-assisted cap 2 other end.
The described length of internal thread in latching segment 1 that is threaded is 15mm-20mm.
The course of work of the present utility model is:
1, get out the degree of depth moderate, diameter than expansion bolt with the slightly little hole of the outside diameter of tapering.
2, the dust in hole is cleared up.
3, the nut hand of expansion bolt is screwed into bolt and compresses metal sleeve.
4, hold the hand that expansion bolt enters wall booster and twist slip prevention part 3, what expansion bolt is entered wall booster is threaded from latching segment and expansion bolt thread connection, until the two tightened by hand.
5, the hand pinching bolt hand-hole assistant device is on the other hand twisted slip prevention part 3 and expansion bolt is aimed at the hole of having bored with the large end of tapering, another hand just can take hammer to aim at power-assisted cap 2 hammering with all strength of expansion bolt booster, until expansion bolt reaches desired depth.
6, expansion bolt is entered wall booster to back out, finish the work.
The beneficial effects of the utility model are:
1, use expansion bolt hand-hole booster can carry out effective protection to expansion bolt end thread, can not occur that expansion bolt end thread is pounded the generation of deformation again;
2, expansion bolt hand-hole booster can be reused, and avoids the waste of man-hour and material;
3, expansion bolt hand-hole booster significantly can reduce the labour intensity of operator;
4, expansion bolt hand-hole booster can significantly improve production efficiency, improve the quality of production;
5, expansion bolt hand-hole booster can avoid workman to cause unnecessary personal injury;
6, the area of section by arranging power-assisted cap and expansion bolt abutting end is greater than the area of section of the power-assisted cap other end, can alleviate the weight of booster, cost-saving, increases the lifting surface area of hammering;
7, screwed hole is blind hole, can ensure locking, but can not be locked.
