Abstract

The utility model discloses an angular wheel roller spanner, which comprises a spanner body and a spanner strip. The angular wheel roller spanner is characterized in that a circular hole of the spanner body is internally provided with an angular wheel rotor, a plurality of angle baffle blocks are arranged between the corner of the angular wheel rotor and a hole wall of the spanner body, a plurality of rollers are arranged between every two adjoining angle baffle blocks, and the spanner strip is inserted into the central hole of the angular wheel rotor. Compared with the existing roller spanner, the angular wheel roller spanner is optimized in changing the star wheel structure of the rotor of the roller spanner into the angular structure, simplifies the shape of the rotor, is very convenient in machining, not only guarantees the machining precision, but also greatly reduces the machining cost.

Description

Horn ring roller spanner

Technical field

The utility model designs a kind of novel horn ring roller spanner, belongs to the instrument class.

Background technology

The roller spanner is a kind of common tool, and the rotor of existing roller spanner is star wheel structure (as shown in Figure 3), and it is complex-shaped, and difficulty of processing is big, and machining accuracy is difficult to control, thereby its processing cost is just than higher.

Summary of the invention

The purpose of this utility model is to improve the deficiency that exists in the prior art, and a kind of processing simple in structure, easy, novel horn ring roller spanner that cost is low are provided.

The technical solution of the utility model is: a kind of horn ring roller spanner, have the body of pulling, pull bar, characteristics are, in pulling the circular hole of body, be provided with the horn ring rotor, the bight of horn ring rotor and pull between the hole wall of body and be provided with the angle block, be provided with roller between two adjacent angle blocks, pull bar and be plugged in the horn ring centre of rotor hole.Wherein, the bight of angle block and horn ring rotor both can be to flexibly connect, and also can be the fixedly connected shape that is integral.

Can also be provided with elastomer between described roller and the angle block.

In order to locate conveniently, locating slot can be set pulling on the sidewall of bar, corresponding, on the sidewall of horn ring rotor, be provided with alignment pin.

Can also be provided with elastic positioning device in the end of pulling bar.

The utility model is compared with existing roller spanner, and its biggest advantage is exactly that rotor with the roller spanner changes angular structure into by star wheel structure, has simplified the profile of rotor, processes very conveniently, can guarantee machining accuracy, has reduced processing cost again significantly.

Below in conjunction with drawings and Examples the utility model is done at length and to be explained.

Description of drawings

Fig. 1-structural representation of the present utility model;

Fig. 2-side view of the present utility model (broken section);

The structural representation of Fig. 3-existing roller spanner.

The explanation of accompanying drawing drawing:

1 pulls body, 2 horn ring rotors, and 3 rollers, 4 angle blocks, 5 pull bar, 6 elastomers, 7 locating slots, 8 alignment pins, 9 pads, 10 jump rings, 11 steel balls, 12 springs.

The specific embodiment

Referring to Fig. 1, Fig. 2, its profile is the same substantially with existing spanner, comprise and pull body 1 and pull bar 5, horn ring rotor 2 is set in the circular hole of pulling body 1, the angle number of horn ring rotor 2 can be arbitrarily, as triangle, four jiaos, five jiaos, hexagonal, heptangle ... can reach according to actual needs and be processed into original design, in the bight of horn ring rotor 2 and pull setting angle block 4 between the hole wall of body 1, be provided with roller 3 between two adjacent angle blocks 4, pull in the centre bore that bar 5 is plugged on horn ring rotor 2, fixing in the both ends of the surface of pulling body 1 with pad 9 and jump ring 10, prevent horn ring rotor 2, angle block 4 and roller 3 drop.

The shape of angle block 4 is irregular, match with the circular hole wall of pulling body 1 in its side, circle diameter is identical with the Circularhole diameter of pulling body 1, match with the bight of horn ring rotor 2 in the another side, and the distribution in the both sides, bight is unequal, the big side of one side is little, and purpose is roller 3 to be in pull the angle of wedge position that forms between body 1 circular hole wall and the horn ring rotor 2.Angle block 4 generally flexibly connects with the bight of horn ring rotor 2, and promptly angle block 4 and horn ring rotor 2 are individualism, two parts of installation separately; In particular cases also can be fixedly connectedly, promptly angle block 4 is fixed as one with horn ring rotor 2, and the shape of this moment promptly is equal to existing star wheel structure rotor.Angle block 4 can be metal (as a steel) material, can be nylon material also, and manufacture craft is simple, and is with low cost.

If when the space between roller 3 and the angle block 4 is excessive, also can between roller 3 and angle block 4, elastomer 6 be set.

Operation principle of the present utility model and using method and existing roller spanner are basic identical, and two ends and the sleeve of pulling bar are used, and are fit to screw (unclamping) screw in the little angle range.When pulling body and clockwise rotate, angle of wedge effect takes place by pulling body circular hole, horn ring rotor and roller three, drive and pull bar and rotate and carry out work, the rotation work of positive and negative both direction can be realized in the two ends of pulling bar.

In the utility model, on the sidewall of pulling bar 5, be provided with locating slot 7, corresponding, on the sidewall of horn ring rotor 2, be provided with alignment pin 8.During use, pull bar 5 and in pulling body 1, can promote the firm position difficult drop-off as required up and down arbitrarily.

To pull bar and cooperate with sleeve closely in order to make, can also be provided with the elastic positioning device that steel ball 11 matches with spring 12 at the both ends of pulling bar 5, pull when preventing work and take place looseningly between bar and the sleeve, influence is used.
