Abstract

The utility model provides a rotary bidirectional ratchet vertical handgrip spanner, which is primarily used in construction of architectural engineering. One end of the vertical handgrip of the spanner is a cone-shaped tip and the other end is an annular head. The inner wall of the annular head is step-like. The ratchet of the rotary bidirectional ratchet vertical handgrip spanner is a double-caliber ratchet. The external surface of the ratchet is step-like, and is provided with an annular tooth zone and an annular slot. The rotary bidirectional ratchet vertical handgrip spanner further comprises an annular fastener which is a C-shaped elastic trip and is used for fixing a ratchet cylinder; a directional brake which is a W-shaped block; steel balls which can push the directional brake; and a spring which can push the steel balls. Each side of the upper end of the directional brake is provided with two teeth which prop the tooth zone. The vertical tip handgrip can be used as a small pry bar in construction. The spanner is simple in construction, has a plurality of functions and uses, which is an ideal substitute of the prior spanner.

Description

The rotating bidirectional ratchet erects the handle spanner

Affiliated technical field:

The utility model belongs to building engineering field, is mainly used in the assembling of steel pipe scaffold in the building engineering construction and the instrument that when dismounting loading and unloading steel pipe clamp is used specifically.

Background technology:

At home in the architectural engineering, the assembling of steel pipe scaffold or dismounting steel pipe card nut all are with double offset ring spanner or open-end wrench, owing to be subjected to spatial constraints during practical operation, generally can not rotate continuously, need rotate to certain angle lifts down spanner and gets back to original angle and operate, repeatable operation just can be finished the mounting or dismounting work of a nut like this, and time-consuming, effort has prolonged the work high above the ground time again.

Summary of the invention:

In order to solve above-mentioned existing problems, the utility model provides a kind of rotating bidirectional ratchet to erect the handle spanner, its simple structure, and easy to use, laborsaving, saving of labor, efficient height, and should be able to shorten the work high above the ground time.

The technical solution of the utility model is achieved in that it is made up of rotating part and standing part and taper tip handle, wherein also comprises the ratchet tube, and spring part, steel ball, loop fasteners are turned round in the direction braking.The rotating bidirectional ratchet spanner can rotate repeatedly according to its arm optimum range and rotary work space, until the tense-lax silk work of finishing nut.

Effect of the present utility model is:

1. because its principle is identical with the reason of bicycle freewheel rotation, different is the rotating bidirectional ratchet spanner, because a direction backstop is turned round in the direction braking, one direction can rotate freely, need not take off from nut during construction, just can directly turn round and turn back to original angle, turn round by regulating the direction braking, up time and inverse time direction can both be worked, and both direction can both make spanner idling slide in the other direction.

2. two of rotating bidirectional ratchet spanner sleeve pipe is the ratchet tube, may be used to nut and tightly unloads work, and taper tip handle can be used as little crowbar and uses.

3. its function is many, and is easy to use, laborsaving, less manpower, and operating efficiency improves 6 times than original.

4. shorten the time of work high above the ground, reduced the danger coefficient of work high above the ground.

Fig. 2 is the utility model decomposing schematic representation

Fig. 3 is the utility model profile

Among the figure: 1, taper tip handle; 2, ring head; 3, ratchet tube; 4, teeth band; 5, the direction braking is turned round; 6, circular hole; 7, riveting axle; 8, rectangle slotted eye; 9, steel ball; 10, spring part; 11, vertical circular hole; 12, teeth band; 13, teeth and ratchet tube just form step; 14, groove; 15, loop fasteners; 16, teeth;

The specific embodiment:

In order to describe structure of the present utility model and characteristics place in detail, in conjunction with the accompanying drawings shown in 1～3, the perpendicular handle spanner of this rotating bidirectional ratchet by: members such as taper tip handle 1, ratchet tube 3, loop fasteners 15, direction braking turn round 5, steel ball 9, spring part 10 constitute.

Taper tip handle 1, one end is the taper tip, and an end is a ring head 2, and a circular hole 6 is arranged at ring head 2 tops, and used for ratchet 3 notes lubricants, 2 lower side of annular have a rectangle slotted eye 8, put the set direction braking and turn round 5; 5 belows are turned round in the direction braking a vertical circular hole 11, for placing steel ball 9, spring part 10; 5 riveting axle 7 is turned round for regulating the direction braking in ring head 2 positive belows; Ring head 2 inwalls are step-like 16.

Ratchet tube 3, interior is teeth band 4, and ratchet tube 3 outsides are teeth band 12, and it is step-like 13 that the ring head outer wall is, and also there is an annular groove 14 in the ratchet outside.

Loop fasteners 15 is C shape spring secures rail to sleeper, in ratchet tube 3 outside grooves 14, and fixed ratchet wheel tube 3.

The direction braking turns round 5, is a W shape block, and the every side in block both sides, upper end has two teeth 16, coincide with ratchet tube 3 outside teeth bands 12.

Steel ball 9 is positioned at the direction braking and turns round 5 belows, spring part 10 tops, and the braking of pushing tow direction turns round 5.

Spring part 10: spring part 10 is positioned at steel ball 9 below circular troughs, all the time be in elastic stage, jack-up steel ball 9,5 belows are turned round in the braking of steel ball 9 jack-up W shape directions, direction braking is turned round 5 and is in an end all the time and contacts with ratchet 3 outside teeth 12, plays ratchet 3 one direction backstops, and a direction can rotate freely, it is more sensitive that its spanner is controlled, and two-wayly allots the raising that reaches operating efficiency relatively.

Using method: the ratchet jacket casing with the rotation reversible ratcheting tool is lived nut, according to silk on the nut or unload the direction of silk and operator custom is regulated the direction braking and turned round, firmly move handle, the rotation proper angle, make spanner get back to suitable location again, firmly move handle repeatedly, till the operation of finishing a nut loading and unloading like this.

This spanner overall package is easy, has improved result of use, and its function is many, and is easy to use, and laborsaving, saving of labor has shortened the danger coefficient of work high above the ground, and operating efficiency improves greatly.
