Based on this, those skilled in the art have provided an anti-drop adjusting bolt to solve the problems set forth in the background art.

SUMMERY OF THE UTILITY MODEL

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to solve to being located some equipment that the range of vibrations is bigger will appear the not hard up problem of cooperation.

In order to solve the technical problem, the utility model discloses a following technical scheme:

an anti-drop jack bolt comprising: the bolt and the nut, the nut is installed at the upper wall of bolt, and nut axle center and bolt axle center coincidence, gear-shaped recess has been seted up to the lower wall of nut.

As the utility model discloses further scheme again: the lower wall surface of the nut is provided with a positioning plate, the upper wall surface of the positioning plate is provided with a lock catch groove, and a lock catch component is arranged in the lock catch groove.

As the utility model discloses further scheme again: the latch assembly includes: the lock catch comprises a lock catch, a lock catch support plate and a lock catch cap; the lock catch supporting plate is arranged in a lock catch groove of the positioning plate, the lock catch is arranged inside the lock catch supporting plate, and the lock catch cap is arranged on the right wall surface of the lock catch.

As the utility model discloses further scheme again: and a return spring is arranged between the lock catch support plate and the lock catch cap.

As the utility model discloses further scheme again: two positioning pins are mounted on the lower wall surface of the positioning plate.

As the utility model discloses further scheme again: the nut is a hexagonal nut.

Advantageous effects

Compared with the prior art, the utility model has the advantages that:

1. the utility model discloses an install on the great equipment of amplitude to current bolt, for example the equipment such as engine, the not hard up phenomenon will appear, has made the design that prevents to drop right, passes through the screw thread when the bolt and installs in the screw hole to carry out anti-drop locking, just so played the effect that prevents to drop, thereby make the use that the bolt can be safer on having the equipment that the vibration range is relatively.

2. The utility model discloses an improve on traditional bolt, just so practiced thrift a lot of costs on the processing aspect, meanwhile, the utility model discloses also can practice thrift very wrong resource on the aspect of design, and the utility model discloses a on being applicable to the bolt of all models on the current market, like this has just greatly promoted the utility model discloses an application scope.

In the figure: 1. a bolt; 2. a nut; 3. positioning a plate; 4. locking; 5. a latch support plate; 6. a locking cap; 7. a return spring; 8. and a positioning pin.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In the specific implementation: as shown in fig. 1 to 4, in the embodiment of the present invention, 1, an anti-dropping adjusting bolt includes: bolt 1 and nut 2, nut 2 installs in the upper wall of bolt 1, and the coincidence of 2 axle centers of nut and 1 axle centers of bolt, and the recess of gear shape is seted up to the lower wall face of nut 2.

Wherein, locating plate 3 is installed to the lower wall of nut 2, and the hasp groove has been seted up to the upper wall of locating plate 3, and installs the hasp subassembly in the hasp groove. The latch assembly includes: a lock catch 4, a lock catch support plate 5 and a lock catch cap 6; the hasp backup pad 5 is installed in the hasp inslot of locating plate 3, and hasp 4 is installed in the inside of hasp backup pad 5, and the right wall at hasp 4 is installed to hasp cap 6. A return spring 7 is arranged between the lock catch support plate 5 and the lock catch cap 6. Two positioning pins 8 are mounted on the lower wall surface of the positioning plate 3. The nut 2 is a hexagonal nut.

The utility model discloses a theory of operation is:

when the utility model is used, firstly, a pin hole is respectively processed at two sides of a threaded hole to be installed for positioning the utility model, then a positioning plate 3 is placed on the upper wall surface of the threaded hole to be installed, two positioning pins 8 are respectively clamped in the pin holes at two sides of the threaded hole, a through hole in the positioning plate 3 and the threaded hole to be installed are kept concentric, then a bolt 1 is installed in the threaded hole to be installed, then the nut 2 is twisted, an operator presses a lock catch cap 6 with hands while twisting the nut 2, a reset spring 7 is compressed between a catch support plate 5 and the lock catch cap 6, a lock catch 4 is attached to the bolt 1, then the bolt 1 and the nut 2 are continuously locked until the lower wall surface of the nut 2 is attached to the upper wall surface of the positioning plate 3, then the operator loosens the hand pressing the lock catch cap 6, reset spring 7 begins to extend between hasp backup pad 5 and hasp cap 6, just so lets hasp 4 to the gear groove internal left-hand thread in the nut 2, then, continues to twist nut 2 until hasp 4 left-hand thread to the gear groove in, has just so accomplished the utility model discloses an installation comes the analysis from mechanical design's angle, because the locking motion pair of the gear groove formation in hasp 4 and the nut 2, has just so prevented bolt 1 in the rotation of Z direction to the complete positioning of traditional bolt has been accomplished.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the technical scope of the present invention, and the technical scope of the present invention is also considered to fall into the scope of the claims.
