On the mechanical equipment of movement, it is desirable that bolt was mounted in threaded hole within the angular length time the phenomenon that being not in loosening, such as: vapour
Bolt etc. on wheel hub, therefore, it is necessary to bolt in equipment run duration after lead to the problem of long afterwards loosen progress
Research and improvement.
Utility model content
One of the purpose of this utility model is in view of the above deficiencies, to provide a kind of elastic fastening bolt, it is expected to solve
In the prior art bolt in equipment run duration after long afterwards generate loosen etc. technical problems.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of elastic fastening bolt provided by the utility model, the bolt includes stud, the inside of the stud
Equipped with bolt is suppressed, the top for suppressing bolt is equipped with stop collar, and the bottom for suppressing bolt is equipped with spring bearer plate, described
Spring bearer plate lower part is equipped with spring.
Preferably, further technical solution is: the top of the stud is turret head, and the middle part of the stud is equipped with
Three-level stepped ramp type through-hole, the diameter of the three-level stepped ramp type through-hole are greater than the diameter for suppressing bolt.
Further technical solution is: the top for suppressing bolt is equipped with cylinder table top, the top of the cylinder table top
Portion is equipped with cross recess, and the middle part for suppressing bolt does not set screw thread, and the bottom for suppressing bolt is equipped with screw thread.
Further technical solution is: the centre of the spring bearer plate is equipped with through-hole, and the through-hole is equipped with screw thread, institute
It states spring bearer plate and is matched with the screw thread for suppressing bolt lower part.
Compared with prior art, the beneficial effects of the utility model first is that: by the way that the inside of stud is set three-level type platform
The middle section diameter of rank through-hole, three-level step through-hole is minimum, and the diameter of middle section is greater than the diameter for suppressing bolt, so that bullet
Pressure bolt can be mounted on inside stud, and a diameter is set at the top of bolt greater than the cylindrical stage for suppressing the diameter of bolt suppressing
Face sets the cruciform groove being recessed inwardly at the top of cylindrical mesa, when in use, user can by Phillips screwdriver or
Person's straight screwdriver is installed, and sets stop collar, stop collar and stud on the cylinder for the top cylindrical shape table top for suppressing bolt
On the groove that sets cooperate axial displacement occurs so that suppressing bolt not and will receive elastic force, will suppress in the middle part of bolt and set
Smooth cylindrical surface, the length of smooth, cylindrical peripheral surface is equal to the length of three-level step through-hole middle section in stud, for reducing bullet
The friction between bolt and stud inner wall is pressed, screw thread is set in the lower part for suppressing bolt, is set suppressing space between bolt and stud
Spring bearer plate, spring bearer plate and is suppressed using being threadedly engaged between bolt, sets spring, the internal diameter of spring in the lower part of spring bearer plate
Greater than the diameter for suppressing bolt, elastic fastening bolt is screwed into the threaded hole of equipment by spanner, screwdriver is recycled, turns
Bolt is suppressed, so that spring bearer plate moves down, to squeeze spring, so that entire elastic fastening bolt is by outside elastic force,
To make the frictional force between the screw thread on elastic fastening bolt and the screw thread of equipment threaded hole increase, so that pine occurs for bolt
Dynamic phenomenon is eased.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for illustrating the utility model one embodiment；
Fig. 2 is the top surface structure schematic diagram of the utility model；
In figure, 1 it is spring, 2 is spring bearer plate, 3 is stud, 4 to suppress bolt, 5 be stop collar.
Specific embodiment
The utility model is further elaborated with reference to the accompanying drawing.
A kind of elastic fastening bolt with reference to shown in Fig. 1, the bolt include stud 3, by installing in the inside of stud 3
Bolt 4 is suppressed, a cylindrical mesa is set at the top for suppressing bolt 4, in the cylinder for the top cylindrical shape table top for suppressing bolt 4
On set stop collar 5, the groove that sets on stop collar 5 and stud 3 cooperates, and axis occurs so that suppressing bolt 4 not and will receive elastic force
To displacement, the middle part for suppressing bolt 4 is set to smooth cylindrical surface, suppresses rubbing between 3 inner wall of bolt 4 and stud for reducing
It wipes, sets spring bearer plate 2 suppressing space between bolt 4 and stud 3, spring bearer plate 2 and suppressing is matched between bolt 4 using screw thread
It closes, sets spring 1 in the lower part of spring bearer plate 2, the internal diameter of spring 1 is greater than the diameter for suppressing bolt 4, by spanner by elastic fastening
Bolt is screwed into the threaded hole of equipment, is recycled screwdriver, is turned and suppress bolt 4, so that spring bearer plate 2 moves down, thus
Spring 1 is squeezed, so that entire elastic fastening bolt is made the screw thread and equipment threaded hole on elastic fastening bolt by outside elastic force
Screw thread between frictional force increase so that there is a phenomenon where loosen to be eased for bolt.
In the present embodiment, for the ease of using, the top of stud 3 is set as turret head, turret head makes having a size of national standard
