Abstract

The utility model discloses a hand tool, particularly a multifunctional spanner for a bicycle, comprising spanner bodies I, II, connecting screws and a press block. Various sizes of spanners and screw drivers for repairing and maintaining the bicycle are designed on the spanner bodies I, II which can be assembled into a whole (can compose the angles of 60 DEG, 120 DEG, 180 DEG, etc.) through the connecting screws and the press block and can also be independently used (the spanner bodies I, II must be separated and simultaneously used when the nuts of the seat pad and the front and the back wheel are loosened and tightened). The multifunctional spanner can conveniently and lightly disassemble, loosen, tighten and regulate all parts of various types of bicycles, having the advantages of simple structure, low cost, small size and convenient use and carrying.

Description

Multifunctional spanner for bicycle

The utility model relates to a kind of hand tools, particularly a kind of bicycle multifunctional wrench.

At present, bicycle still is the main vehicles that people use always, for it maintenance and the maintenance just corresponding instrument must be arranged.The maintenance tool that existing bicycle is commonly used, the sets of tools such as normally dead, adjustable wrench and screwdriver, these instrument volumes are big, Heavy Weight, price height, and carry inconvenience.In order to address this problem, Chinese patent CN2038046U has announced a kind of " bicycle folding combination wrench ", and it is that three combination wrench bodies are housed in handle, at one end connects and can be around its Rotate 180 ° by fixed axis.Though the spanner of this structure can satisfy the needs of the ordinary maintenance and the maintenance of bicycle, complex structure, cost of manufacture is higher, and weight is also heavier, and volume ratio is bigger, uses and carries not very convenient.

The purpose of this utility model is to design the multi-functional energy of a kind of bicycle spanner for overcoming above-mentioned weak point, and it can not only satisfy the needs of the ordinary maintenance and the maintenance of bicycle, and simple in structure, cost is low, in light weight, volume is little, uses and carries all very convenient.

The purpose of this utility model reaches in the following way: the bicycle multifunctional wrench is made up of wrench body I, II, attachment screw and briquetting; The spanner and the screwdriver of the required all size of maintenance and maintenance bicycle have been designed on wrench body I, the II; There is the regular polygon step at the middle part of attachment screw; Briquetting is an annular, the internal thread that matches with attachment screw is arranged in the middle of it, and there is the shirt rim outer, have on it at least one pair of be symmetrical distribution, be used to regulate the mouth of pulling that the rim spoke uses; Wrench body I, II are contained on the regular polygon step at attachment screw middle part by the just polygon hole on it; Briquetting is contained on the attachment screw by screw thread.

The utility model is compared with existing bicycle folding combination wrench owing to adopt as above design, have simple in structure, cost is low, in light weight, physique is little, advantage such as easy to use and carry.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1;

Specify the accompanying drawing of accompanying drawing 1 for the utility model summary.

Below in conjunction with drawings and Examples detailed structure of the present utility model is further described:

Bicycle multifunctional wrench (16) as shown in drawings, wrench body II (17) attachment screw (18), briquetting (19) is formed, the wrench body I, II is shaped with the thick intermediate carbon steel sheet punching out of 3mm, design is useful on the screwdriver (1) of the various slotted head screws of degree of tightness on it, the spanner (2) that is used for degree of tightness trailing wheel axle bumper and pedal spindle, the spanner (3) that is used for degree of tightness pedal spindle nut and front-wheel axle bumper, the spanner (4) that is used for degree of tightness tripod axis nut, (6), be used for degree of tightness tap inserted link and tripod anterior cannula, the spanner (5) of the nut of junction, front fork three position, (10), be used for dismounting and adjust the hexagonal endoporus (7) of front axle and seat cushion, the hexagonal endoporus (8) that is used for the degree of tightness rear axle, the hexagonal endoporus (9) that is used for top, degree of tightness tap center screw is used to regulate the pin (11) of axis gap nut and dismounting flywheel lid and be respectively applied for degree of tightness M4, M6 and M5 hex screw, the spanner of nut (13), (13) and (14) etc.; Attachment screw (18) middle part is the regular hexahedron step that can cooperate with the hexagonal endoporus (8) on wrench body I, the II; There are two pairs to be pull mouthful (15) symmetrical distribution, that be used to regulate the rim spoke on the shirt rim of briquetting (19) outer; Wrench body I, II are contained on the regular hexahedron step at attachment screw middle part by the hexagonal endoporus (8) on it, can form 60 °, 120 ° and 180 ° of three angles mutually, screw on briquetting wrench body I then, II just compresses the location.Because location and torsion mainly act on the hexahedron of locating shaft, briquetting just prevents wrench body I, II axial float, so the briquetting only with hand has been tightened just.Wrench body I, II can be assembled into one, also can be singly only independent the use (when degree of tightness seat cushion and front and back wheel nut the wrench body I, II must be separated and use simultaneously), can very make things convenient for, all parts of dismounting like a cork, degree of tightness and the various model bicycles of adjusting.
