Abstract
The utility model discloses a single-direction return-proof bolt for overcoming the prior problems of easy detachment, which comprises a bolt body, a Chinese character 'yi' or 'shi' latch which is arranged on the head of the bolt body. The single-direction return-proof bolt is characterized in that a wedge face is prepared on one side of the bolt body head and a boss corresponding to the latch along the reverse bolt rotation direction. By adopting the bolt of the structure, the bolt can be assembled on various objects conveniently, a screw driver can slide on the wedge face when the screw driver is applied to detach, thereby reaching the goal of preventing the detachment, because the wedge face is prepared on one side of the boss which corresponds to the latch along the reverse bolt rotation direction.
Description
Technical field
The utility model relates to a kind of bolt, and is particularly a kind of by the fastening bolt of bottle opener.
Background technique
Existing by the fastening bolt of bottle opener, it is that termination by bottle opener is stuck in the in-line or cross bath of bolt top, comes fastening by external force Rotating opener handle then and unloads bolt.This mode makes that the bolt installation and removal are all very convenient, but this has made many chances equally also for some offenders.For example: for easy for installation, the car plate of many automobiles all is installed on the automobile by bolt; But this car plate is stolen through regular meeting.
The model utility content
To go up this and state defective in order to overcome, the purpose of this utility model be to provide a kind of simple in structure, prevent the unidirectional bolt that resists back dismantled.
In order to achieve the above object, the unidirectional bolt that resists back of the present utility model comprises a bolt body, is provided with in-line or cross grooving at the bolt body head, it is characterized in that a side of anti-bolt rotation direction is shaped on sphenoid surface on described bolt body head and the pairing boss of grooving.
Particularly, the lower surface one at described bolt body head is shaped on anti-skidding packing ring.
Particularly, also comprise one with the suitable nut of bolt body, described nut outer surface is smooth cylindrical.
Particularly, also comprise the metal bottom cover that an opening makes progress, the bottom middle part is provided with and mounting hole, and described bolt body is arranged in the mounting hole; In the position of bottom short transverse middle part or middle and lower part is circumferential along bottom, be provided with 3-10 protruding; One can be fastened on the metal top cover that Open Side Down in the bottom, and the loam cake lower limb outwards is integrally formed with the shirt rim of a radius greater than loam cake excircle radius; Wherein, the radius of loam cake shirt rim and bottom inner circumference radius are suitable; When loam cake was fastened in the bottom by external force, the shirt rim was positioned under the projection.
Particularly, the longitudinal section of above-mentioned projection is roughly an acute angle, and the bottom of this acute angle and its below bottom side are 90 degree substantially, and the hypotenuse of this acute angle and its top bottom side are the obtuse angle of 95-175 degree substantially.
Particularly, outside bottom, be shaped on depression in described bottom inside side walls bottom along bottom sidewall circumference.
Adopt the bolt of above-mentioned structure, can be installed in easily on the various objects, but owing to a side of anti-bolt rotation direction on the pairing boss of grooving is shaped on sphenoid surface.Like this, when dismantling with bottle opener, bottle opener then can skid on sphenoid surface, thereby reaches the purpose of anti-dismounting.
Description of drawings
Fig. 1 is the unidirectional perspective view that resists back bolt of the utility model.
Fig. 2 is the structural representation that the embodiment of nut is installed.
Fig. 3 is another embodiment's of the utility model a structural representation.
Fig. 4 is the exploded view of middle loam cake embodiment illustrated in fig. 3 and bottom.
Embodiment
Below in conjunction with drawings and Examples the utility model is done to improve further.
Fig. 1, shown in Figure 2, the unidirectional bolt that resists back of the present utility model, comprise a bolt body 9, be provided with in-line or cross grooving at the bolt body head, a side of anti-bolt rotation direction is shaped on sphenoid surface 91 on described bolt body head and the pairing boss of grooving.In use for non-skid, be shaped on anti-skidding packing ring in the lower surface one of described bolt body head.In order to prevent that further bolt is disassembled, also comprise one with the suitable nut 8 of bolt body, described nut outer surface is smooth cylindrical.Like this, can prevent from nut to be twisted by instrument.
As shown in Figure 3, further improve as the utility model, also comprise the metal bottom cover 1 that an opening makes progress, bottom middle part is provided with mounting hole, is provided with 3-10 protruding 2 in the position of bottom short transverse middle part or middle and lower part is circumferential along bottom; One can be fastened on the metal top cover 3 that Open Side Down in the bottom, and the loam cake lower limb outwards is integrally formed with the shirt rim 4 of a radius greater than loam cake excircle radius; Wherein, the radius of loam cake shirt rim and bottom inner circumference radius are suitable; When loam cake was fastened in the bottom by external force, the shirt rim was forced through projection by the elasticity of its metal self, is positioned under the projection.
Bottom in the said structure and loam cake select any metal material for use, but destroyed for preventing for more time, should select for use material relatively harder, as iron, steel etc., preferably can select stainless steel for use.Above-mentioned projection should be less, reducing the gap between loam cake and the bottom, inserts between loam cake and bottom by instrument preventing to greatest extent.The quantity of projection can be set according to the radius of bottom and loam cake, generally can be selected in 3-10, and diameter is less, as is used for installing car plate, is raised with that 3-6 is individual to get final product on it.When too many or projection of projection quantity is big slightly, then can strengthen the external force of loam cake when the bottom clinching.
During use, only need to pass mounting hole on the bottom, then bottom is fixed on the fixation, with hand or other instrument the loam cake clinching is got final product in bottom then with bolt body.
Improve further as the foregoing description, as shown in Figure 3, Figure 4, the longitudinal section of above-mentioned projection is roughly an acute angle, and the bottom of this acute angle and its below bottom side are 90 degree substantially, and the hypotenuse of this acute angle and its top bottom side are the obtuse angle of 95-175 degree substantially.
Further, also can outside bottom, be shaped on depression 5 along bottom sidewall circumference in above-mentioned bottom inside side walls bottom.With ccontaining loam cake shirt rim,, strengthen its anti-dismounting performance to reduce the gap between loam cake and bottom to greatest extent.
In summary, the utility model is simple in structure, and is easy to use, and anti-dismounting ability is stronger, is that example is tested to select stainless steel for use, and instrument can't be opened in 20 minutes usually.
