Abstract
The utility model discloses a multi -functional bolt, including bolt head and shank of bolt, the shank of bolt sets up the bolt bottom, the surface of shank of bolt is equipped with the spiral shell, shank of bolt bottom, and the inside that is located the shank of bolt is equipped with a protruding type recess, a pin has been placed to the inside of protruding type recess, the pin with be equipped with a coil spring between the top of protruding type recess. The utility model discloses, device design is reasonable, simple structure, the operation of being convenient for, resources are saved, save labour, save time, the low price, through the spring action, prevent to become flexible because of what long -time vibrations produced, simultaneously, can use the spanner, wedge etc. Are to its construction, and are very convenient, are fit for extensively promoting.
Description
Technical field
The utility model relates to component of machine technical field, particularly relates to a kind of Multifunctional bolt.
Background technique
Along with the fast development of society, some big machineries become the main flow of daily production, but big machinery is when assembling, and needing to use a requisite component of machine, is bolt, for two articles is fastening.
At present, a kind of structure of comparatively simple a kind of bolt comprises bolt body and spiral pad, during use, by spiral pad is placed between fastener and bolt body, prevent bolt from producing because shaking for a long time loosening, fastener is departed from, but due to spiral pad and bolt body one each other, when dismantling, being easy to lose spiral pad, also will taking a lot of trouble during placement, simultaneously because bolt head is generally hexagonal structure, just can must use with spanner, comparatively time-consuming, be not suitable for extensive popularization.
Model utility content
For solving above-mentioned technological deficiency, the utility model object is to provide a kind of Multifunctional bolt, and by spring action, what prevent from producing because shaking for a long time loosens; Meanwhile, can use spanner, chock etc. are to its construction, very convenient.
Scheme of the present utility model is as follows: a kind of Multifunctional bolt, comprise bolt head and bolt shank, described bolt shank is arranged on described stud base, it is characterized in that: the outer surface of described bolt shank is provided with spiral shell, bottom described bolt shank, and the inside being positioned at bolt shank is provided with a convex groove, the inside of described convex groove is placed with a pin, is provided with a helical spring between the top of described pin and described convex groove.
Described bolt head is provided with interior hexagonal groove, and the middle part of described interior hexagonal groove is provided with a cross recess.
One end that in described convex groove, diameter is less is arranged on the bottom of described screw rod.
The head diameter of described pin is greater than the diameter in the middle part of it, and the diameter of described pin head is identical with the diameter of larger one end in described convex groove, and the diameter bottom described pin is identical with the diameter of one end less in described convex groove.
Length in the middle part of described pin is greater than the length 5-10 millimeter of one end that diameter is less in described convex groove.
The utility model apparatus design is reasonable, and structure is simple, and convenient operation, economizes on resources; Saving of labor, to save time, cheap; By spring action, what prevent from producing because shaking for a long time loosens; Meanwhile, can use spanner, chock etc. are to its construction, very convenient, are applicable to extensively promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of bolt head in the utility model;
Fig. 3 is the utility model structural representation operationally;
Wherein: 1, bolt head; 11, cross recess; 12, interior hexagonal groove; 2, bolt shank; 3, screw thread; 4, convex groove; 5, helical spring; 6, pin.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As depicted in figs. 1 and 2, a kind of Multifunctional bolt, comprise bolt head 1 and bolt shank 2, described bolt shank 2 is arranged on bottom described bolt head 1, the outer surface of described bolt shank 2 is provided with screw thread 3, the bottom of described bolt shank 2, and the inside being positioned at bolt shank 2 is provided with a convex groove 4, the inside of described convex groove 4 is placed with a pin 6, is provided with a helical spring 5 between the top of described pin 6 and described convex groove 4.
Described bolt head 1 is provided with interior hexagonal groove 12, and the middle part of described interior hexagonal groove 12 is provided with a cross recess 11.
One end that in described convex groove 4, diameter is less is arranged on the bottom of described screw rod 2.
The head diameter of described pin 6 is greater than the diameter in the middle part of it, and the diameter of described pin 3 head is identical with the diameter of larger one end in described convex groove 4, and the diameter bottom described pin 3 is identical with the diameter of one end less in described convex groove 4.
Length in the middle part of described pin 6 is greater than the length 5-10 millimeter of one end that diameter is less in described convex groove 4.
As shown in Figure 3, concrete, during use, spanner or chock is used by bolt to rotate in the tapped hole of fastener, pin 6 is made to enter in convex groove 4 completely, now because the reaction force of helical spring 5 makes the occlusion between screw thread 3 more tight, effectively prevent because of vibrations for a long time, and the loosening phenomenon occurred.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned mode of execution and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection domain of the present utility model.
