Abstract
The utility model discloses a compound material reinforced ratchet spanner, comprising a spanner handle, a cover plate and a ratchet component. The spanner handle comprises a handle part and a spanner head. The board surface of the handle part is provided with a through hole. The spanner head is a frame body used for holding the ratchet component which is elliptical. The front end of the top surface of the spanner head is provided with a shaft hole. Both sides of the center of the spanner head is provided with round holes. The back end is provided with a pin hole. Compound material is used for coating the part from the handle part to a holding space at the bottom end of the spanner head. A stair surface and a groove are extended. The circumference at the front end of the spanner head is provided with notches. The front end of the cover plate is provided with a convex block. A shaft hole, a threaded hole and a pin hole which are arranged on the board surface of the cover plate are respectively corresponding to the shaft hole, the round hole and the pin hole on the spanner head. The spanner of the utility model has good intensity and long service life.
Description
The utility model relates to a kind of spanner, and particularly a kind of composite is strengthened ratchet spanner.
Glass fibre, the material that carbon fibre material etc. are industrial, at present industrial be to be used to be used as reinforcement, use the shortcoming of supplying the finished product undercapacity, yet complete substituted metal material also arranged and make finished product, for example more common ratchet spanner major part is that main material forms moulding integratedly with the glass fibre at present, the general integrated ratchet spanner of glass fibre that adopts, not only weight is lighter in the use, and can not get rusty, but main two of ratchet spanner partly are shank and ratchet assembly, shank is one-body molded with glass fibre, and the spanner that is distinguished into handle and is extended by an end of handle, handle was embedded with reinforcing chip in advance before moulding, use the intensity of reinforcement handle, and spanner is the ducted body that central authorities connected and be provided with endoporus, to hold ratchet assembly; Do not cover any reinforcing body owing to bury in the spanner, and the peripheral wall surface of spanner is thinner, so, if when operation drop ground or when being subjected to the collision of improper external force of spanner, often cause easily that spanner is injured, unfilled corner or the phenomenon of breaking.
Main purpose of the present utility model is to be to provide a kind of composite to strengthen ratchet spanner, be integral the trigger piece of type by the metal sheet punch forming, to improve the relatively poor shortcoming of spanner intensity of ratchet spanner in the past, spanner can not be damaged, when collided by improper external force to increase the service life.
A kind of composite that the utility model proposes is strengthened ratchet spanner, this spanner comprises trigger piece, cover plate and ratchet assembly, it is characterized in that: trigger piece is struck out one-piece type by metal sheet, the spanner that trigger piece is distinguished into shank and is extended by an end of shank, longitudinally be provided with perforation on the plate face of shank, the perforation the when composite layer (as glass fibre, carbon fiber) of confession outer rim is Overmolded is affixed; Spanner is the framework of elliptical shape, and for ccontaining ratchet assembly, the front end of the top surface of spanner is provided with axis hole, and central authorities are provided with circular hole, and the rear end is provided with tip hole.
Cover plate is covered in the bottom of spanner, and the plate face of cover plate is provided with axis hole, screw and tip hole, and the axis hole on the cover plate, screw and tip hole correspond respectively to axis hole, circular hole and the tip hole on the spanner.
That is to say that the utility model proposes a kind of composite strengthens ratchet spanner, this spanner comprises trigger piece, cover plate and ratchet assembly, it is characterized in that: described trigger piece is one-piece type by the metal sheet punch process, the spanner that described trigger piece is divided into shank and is extended by an end of described shank, longitudinally be provided with perforation on the plate face of described shank, the framework of described spanner ovalize, be equipped with ratchet assembly in the described spanner, the front end of the top surface of described spanner is provided with axis hole, the central authorities of described spanner are provided with circular hole, the rear end of described spanner is provided with tip hole, described cover plate is covered in the bottom of described spanner, the plate face of described cover plate is provided with axis hole, screw and tip hole, the axis hole of described cover plate, axis hole on screw and the corresponding described spanner of tip hole difference, circular hole and tip hole;
The periphery of described spanner front end is provided with breach, and the front end of described cover plate is provided with projection;
The described spanner outside has composite layer, and described composite layer is coated to by described shank in the accommodation space of described spanner bottom, is provided with cascaded surface and groove on the composite layer of described spanner bottom.
Combination by above-mentioned each member can obtain the quite high ratchet spanner of intensity, and trigger piece is the rigid body of metal material, so intensity is fine, helps the raising of spanner intensity, uses to prevent to damage, and increases the service life.Details are as follows for its advantage:
(a) trigger piece is the integrated member of metal material, so the spanner rigidity of trigger piece front end is fine, the ability of bearing strength improves, and has suitable high economic worth.
(b) since the bearing strength of spanner improve, so the injured unfilled corner that is caused in the time of must not fearing careless collision or construction wrong again in the use, the defective of breaking or the like are just preventing the ratchet spanner damage, are improving service life.
(c) shank part of existing ratchet spanner is coating glass fibre during moulding, be to use the metal reinforcement sheet to be embedded in the shank part of ratchet spanner, to reach the purpose that shank part intensity improves, but, can't extend to the place that shank part engages with spanner, so the intensity in the place that shank part engages with spanner is often relatively poor, is damaged easily during use; And the trigger piece that the utility model proposes is taked integrated structure, coats glass fibre again and makes it reinforcement, so intensity is fairly good, is difficult for impaired.
(d) design of the projection established of cover plate front end and trigger piece front end breach provides a kind of effect of the combination of correcting rapidly, to increase work efficiency.
Comprehensive the above, a kind of composite that the utility model proposes is strengthened ratchet spanner, by integrated trigger piece structure to improve the intensity of ratchet spanner, not only not fragile but also long service life.
Technology, means are now enumerated preferred embodiment and conjunction with figs. for achieving the above object, are described in detail as follows, wherein
Fig. 1 is the trigger piece of the utility model preferred embodiment, the stereo appearance figure of cover plate;
Fig. 2 is the combination generalized section of the utility model preferred embodiment;
Fig. 3 is the bottom view of the utility model preferred embodiment.
The composite that the utility model proposes is strengthened ratchet spanner, sees also shown in Fig. 1,2, and ratchet spanner comprises members such as trigger piece 10, cover plate 20 and ratchet assembly 30.
During combination, see also shown in Fig. 1,3, the trigger piece 10 that at first will coat glass fiber-reinforced material oppositely is provided with, then, ratchet assembly 30 is inserted in each hole of spanner 12 according to predetermined direction, program, by the time after each member location of ratchet assembly 30, cover and make each borehole jack on the cover plate 20 on ratchet assembly 30 cover plate 20, utilize one group of flat head screw 40 that trigger piece 10, cover plate 20 lockings are combined into one again, whether last test commutation button 36 can normally use, so, the utility model just makes up and finishes.
