Description

U type clamp fixation device

The utility model relates to the mechanical grip jockey, a kind of specifically U type clamp fixation device.

In numerous mechanical grip jockeys; U type card is a kind of widely used part that grips; it has simple in structure; advantage easy to use; in the prior art; U type card or single use or two uses; its structure is in the axostylus axostyle upper end of U type card and is shaped on screw thread; this screw rod stretches out from the respective aperture of fixed head and uses nut check; the lower surface of fixed head directly is pressed in fastened connecting elements; this structure is suitable for being clamped and connected of some stabilizing members; but to the member of some movable machineries member of the sower type machinery in the agricultural machinery for example, the U type card of prior art can be because of vibrations; jolt and become flexible, make the member clamping shakiness that is held connection; influence the work quality of movable machinery, even cause the accident or shut down.

The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of U type clamp fixation device that has improved is provided, and clamping is firm, be not afraid of vibrations, and simple in structure, easy and simple to handle, cost is lower, is particularly suitable for for example use of agricultural seeding machine type machinery of movable machinery.

The purpose of this utility model is achieved in that

A kind of U type clamp fixation device is used for two or more members are fixed together, and mainly is made up of U type card and fixed head, it is characterized in that it is configured to:

One fixed head is square, the four jiaos of circular holes that dress U type card is arranged in its plane, and planar central is shaped on screw;

Two U-shaped cards, shape is identical, and two tops of U type axis bar have the circular hole of four jiaos of thin neck and fixed heads corresponding;

One tight fixed bolt nut is installed in the fixed head center screw;

One backing plate, its size suitably can be placed in the space between the two U type cards below the fixed head, and the last planar central of this backing plate is shaped on and the corresponding taper hole of tight fixed bolt head;

The assembly relation of above-mentioned each assembly is: the corresponding circle hole that the thin neck of two U type axis masthead ends penetrates fixed head becomes non-removable fixedly connected with fixed head; Penetrate by the member of tightening in the U type card, backing plate is placed in by between tightening member upper surface and the fixed head lower surface, tight fixed bolt is screwed into by fixed head upper end and with nut check, the lower end of tight fixed bolt holds out against the corresponding taper hole into the backing plate center, and backing plate is pressed on by the member of tightening.

During enforcement, the shape of cross section of described U type card can be circular, square; The shape of described backing plate can be square pad, planchet.

The utility model has following actively useful effect:

1, clamping is firm, is not afraid of vibrations:

Two U type cards of present technique totally four pole axles and fixed head are fixedly connected as integral body with welding or riveted joint mode, be connected on the bottom bar that the member lower end is supported in two U type bars, the upper end is subjected to compressing of backing plate, this thrust is from the pressure of tight fixed bolt to the other side, the application point of this thrust is positioned at the i.e. center of four pole axles of two U type cards, backing plate center, make and be held member is subjected to mid point just as two strutbeams pressure, thereby clamping is firm, and general vibrations, jolting to make that it is loosening, shock resistance is strong.

2, simple in structure, easy to use:

If the double-U-shaped card of prior art, need tighten the nut of four axle end, not only waste time and energy, and possibility degree of tightness difference, stressed irregular, the U type clamp fixation device of use present technique only needs a fastening holding screw, not only time saving and energy saving, and stress helps fastening clamp.

3, connect the structure of setting up a backing plate between clamp structure and the fixed head being held, not only make stressed evenly, also can prevent to be connected deformation of members.

4, applied widely, be applicable to movable machinery and non-movable machinery, being specially adapted to the agricultural seeding machine type has the upper and lower machinery that jolts, shakes to use in work.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the end view of Fig. 1.

U type clamp fixation device of the present utility model is used for two or more members are fixed together, and mainly is made up of U type card 1 and fixed head 2, please refer to Fig. 1 Fig. 2 Fig. 3, and it is configured to:

Fixed head 2 is square, the four jiaos of circular holes that dress U type card is arranged in its plane, and planar central is shaped on screw;

Two U-shaped cards 1 and 1 ', shape is identical, and two tops of U type axis bar have thin neck 101 corresponding with the circular hole of 2 four jiaos of fixed heads;

One tight fixed bolt 3 is installed in the screw at fixed head 2 centers;

One backing plate 4, its size suitably can be placed in the two U type cards 1 and 1 of fixed head 2 belows ' between the space in, the last planar central of this backing plate is shaped on and the corresponding taper hole of tight fixed bolt 3 heads;

The assembly relation of above-mentioned each assembly is: the corresponding circle hole that the thin neck 101 of two U type axis masthead ends penetrates fixed head 2 and fixed head 2 are with welding or rivet into non-removable fixedly connected; Penetrate in the U type card by the member 6 and 7 of tightening, backing plate 4 is placed in by between the lower surface of the upper surface of tightening member 6 and fixed head 2, tight fixed bolt 3 is screwed into and is locked with nut 5 by the upper end of fixed head 2, the lower end of tight fixed bolt 3 holds out against the corresponding taper hole into backing plate 4 centers, and backing plate 4 is pressed on by the member 6 of tightening.

During enforcement, described U type card 1 and 1 ' shape of cross section can be circular, square; The shape of described backing plate 4 can be square pad, planchet.

During enforcement, the bottom bar 102 of described U-shaped bar can be seen Fig. 3 for straight-bar according to the member shape of fastened connection, also can be bow (accompanying drawing does not show).
