Abstract
The structure preventing bolt rotation and get loose, it is made up of bolt, mounting plate, snap ring and foam; Wherein: the stud top of this bolt has one section of square hanging platform; This mounting plate has the square mounting hole corresponding to square hanging platform; This snap ring is by spring steel material snap ring, and it is by the multiple fan-deck card dog collars connected in an annular ring around forming, and multiple fan-shaped claw top forms a bayonet socket; This foam adopts EPDM material, and has a bolt penetration hole.The utility model component make simple, required precision is not high, manual operations, need not by extra adjustable spanner, scene or outdoor assembling, maintenance can be widely used in, narrow limitation suffered by its use is very little, especially when bolt situation about being arranged on as inside cannot clamp, effectively can overcome these difficulties.
Description
Technical field
The utility model relates to the fastening structure field, particularly a kind of structure preventing bolt rotation and get loose of the process industries such as all kinds of thin-wall metal sheet material, tubing.
Background technique
Along with manufacturing development, a lot of large snap bolt is widely used, and the structure of existing large snap bolt and mounting plate as shown in Figure 1, 2.Shaft due to bolt is circular, and the mounting hole of mounting plate is also circular, the phenomenon that therefore there will be bolt rotation when mounted and get loose.
Model utility content
The purpose of this utility model is to provide a kind of structure preventing bolt rotation and get loose, mainly solve the technical problem existing for above-mentioned prior art, the utility model structural elements makes simple, required precision is not high, and manual operations, need not by extra adjustable spanner, scene or outdoor assembling, maintenance can be widely used in, narrow limitation suffered by its use is very little, especially when bolt situation about being arranged on as inside cannot clamp, effectively can overcome these difficulties.
For achieving the above object, the technical solution of the utility model is:
The structure preventing bolt rotation and get loose, is characterized in that: it is made up of bolt, mounting plate, snap ring and foam; Wherein: the stud top of this bolt has one section of square hanging platform; This mounting plate has the square mounting hole corresponding to square hanging platform; This snap ring is by spring steel material snap ring, and it is by the multiple fan-deck card dog collars connected in an annular ring around forming, and multiple fan-shaped claw top forms a bayonet socket; This foam adopts EPDM material, and has a bolt penetration hole.
The described structure preventing bolt rotation and get loose, is characterized in that: this snap ring has gap between adjacent fan-shaped claw.
The described structure preventing bolt rotation and get loose, it is characterized in that: this bolt is inserted in foam and mounting plate successively, and square hanging platform is snapped in square mounting hole, this snap ring is inserted in bolt by the bayonet socket between fan-shaped claw and fixes in the screw thread of bolt penetrating the Bolt to position of mounting plate.
The utility model has the advantages that: in the utility model, after bolt being inserted in foam, load mounting plate, due to the mutual restraint of liberty degree of square area, cause bolt cannot rotation; Snapped in along bolt across mounting plate by snap ring, because of spring steel good springiness, snap ring can smooth and easyly manually snap in screw thread corresponding to bolt, plays the effect preventing bolt from getting loose; Because the extruding of uneven formula can be realized between bolt and foam, allow the run-off the straight of bolt body, and it is fixing not affect nut installation, indirectly increases the adjustment activity of bolt, the requirement of reduction holes position accuracy of manufacturing.

Embodiment
Refer to Fig. 3-6, the utility model discloses a kind of structure preventing bolt rotation and get loose.As shown in the figure: it is made up of bolt 1, mounting plate 2, snap ring 3 and foam 4; Wherein: the stud top of this bolt 1 has one section of square hanging platform 11; This mounting plate 2 has the square mounting hole 21 corresponding to square hanging platform 11; This snap ring 3 is by spring steel material snap ring, and it is that multiple fan-shaped claw 31 top forms a bayonet socket 32 by the multiple fan-shaped claw 31 connected in an annular ring 30 around forming; This foam 4 adopts EPDM material, and has a bolt penetration hole 41.
In the utility model part processing in it is to be noted that
1, square its size of mounting hole 21 need be greater than the size of bolt square hanging platform 11, and both guarantees are Spielpassung, and monolateral Spielpassung amount is depending on Bolt sizes.
2, foam compressibility and compressional deformation: compressibility gets 50%, thickness TV structure space and determining.
As preferred structure, as Fig. 5, this snap ring 3 has gap between adjacent fan-shaped claw 31.
During the utility model structure installment, as shown in Figure 7: this bolt 1 is inserted in foam 4 and mounting plate 2 successively, and square hanging platform 11 is snapped in square mounting hole 21, this snap ring 3 is inserted in bolt 1 by the bayonet socket 32 between fan-shaped claw 31 and fixes in the screw thread of bolt to be located by the bolt 1 penetrating mounting plate 2.
By above-mentioned package assembly, after bolt being inserted in foam, load mounting plate, due to the mutual restraint of liberty degree of square area, cause bolt cannot rotation; Snapped in along bolt across mounting plate by snap ring, because of spring steel good springiness, snap ring can smooth and easyly manually snap in screw thread corresponding to bolt, plays the effect preventing bolt from getting loose; Because the extruding of uneven formula can be realized between bolt and foam, allow the run-off the straight of bolt body, and it is fixing not affect nut installation, indirectly increases the adjustment activity of bolt, the requirement of reduction holes position accuracy of manufacturing.
Be only preferred embodiment of the present utility model in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
