Abstract
The utility model relates to a bolt dropping prevention device which comprises a base plate and a bolt connected on the base plate. The bolt dropping prevention device further comprises a fixing frame which is fixedly connected with the bolt and a clamping plate which is connected with the fixing frame, and the fixing frame and the clamping plate are respectively placed on two sides of the base plate. The fixing frame which is fixedly connected with the bolt and the clamping plate which is connected with the fixing frame are placed on the two sides of the base plate, and the fact that the bolt can not drop out accidentally after a nut drops out is guaranteed.
Description
Technical field
The utility model belongs to the link field, is specifically related to a kind of bolt anti-dropping apparatus.
Background technique
In industrial production or daily life, often two objects need be fixed together, general common employing screw bolt and nut is fixedly connected with two objects, and when needs demounting bolt and nut, or screw bolt and nut often drops easily because external causes such as vibration exist down again, when these two objects are in specific position (as high altitude environment), dropping of screw bolt and nut can produce potential safety hazard or cause other bad problems.
People such as Nian Zhouming outstanding person have applied for a kind of nut anti-dropping device, this device comprises the nut and bolt that first object and second object are fixed together, be used for nut is contained on first object anti-lost, described anti-lost comprise and the interference fit portion of the first object interference fit and and the first object Spielpassung between the auxiliary section, crack.Interference fit produces precompression and then produces frictional force and makes anti-lost firmly to fix when assembling, guarantees that nut does not drop; In when dismounting during bolt, nut produces axial extruding force to anti-lost, makes anti-lost interference fit portion direction distortion, has increased anti-lost frictional force greatly, has effectively prevented dropping of nut.
So far, though some innovation and creation about nut anti-dropping device have been arranged, for how preventing that technology or device that bolt drops from still being few.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of bolt anti-dropping apparatus is provided, this device comprises the fixing frame that is connected with bolt that is positioned at the substrate both sides and the clamping plate that are connected with fixing frame, guarantees can accident not drop after bolt unclamps.
For solving above technical problem, the technological scheme that the utility model is taked is:
A kind of bolt anti-dropping apparatus comprises substrate, is connected the bolt on the substrate, and the bolt anti-dropping apparatus also comprises the fixing frame that is connected with bolt, the clamping plate that are connected with fixing frame, and fixing frame and clamping plate lay respectively at the both sides of substrate.
Preferably, fixing frame is provided with a barb, offers attachment hole on the clamping plate, and described barb passes substrate and penetrates this attachment hole.
Preferably, offer a chute on the substrate, bolt passes this chute movably along the chute length direction, and the width of described chute is less than the size of described fixing frame.
Further preferably, barb passes chute and penetrates in the attachment hole on the clamping plate.
Preferably, the substrate top offers a through hole that supplies fixing frame to pass, and described through hole links to each other with chute.
Preferably, all offer a circular hole that supplies bolt to pass through on fixing frame and the clamping plate.
Because the employing of above technological scheme, the utility model compared with prior art has following advantage:
1, the utility model is by being provided with the fixing frame that is connected with bolt and the clamping plate that are connected with fixing frame, and fixing frame and clamping plate lay respectively at the both sides of substrate, guaranteed that the nut back bolt that drops can accident not drop;
When 2, the barb that arranges on the utility model fixing frame has effectively prevented the installation nut, bolts and nuts generation transfer.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic representation of the present utility model;
Among the figure: 1, substrate; 2, bolt; 3, fixing frame; 4, clamping plate.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further elaborated.Should be understood that specific embodiment described herein is for explanation basic principle of the present utility model, major character and advantage, and the utility model is not limited by the scope of following examples.
As Fig. 1 ~ shown in Figure 2, the bolt anti-dropping apparatus that the utility model provides, comprise substrate 1, be connected the bolt 2 on the substrate 1, the bolt anti-dropping apparatus also comprises the fixing frame 3 fixedly connected with bolt 2, the clamping plate 4 that are connected with fixing frame 3, and fixing frame 3 and clamping plate 4 lay respectively at the both sides of substrate 1.
Particularly, all offer a circular hole that supplies bolt 2 to pass through on fixing frame 3 and the clamping plate 4, also be provided with a barb on the fixing frame 3, offer attachment hole on the clamping plate 4, offer a chute on the substrate 1, bolt 2 passes this chute 1 movably along the chute length direction, substrate 1 top offers a through hole that supplies fixing frame 3 to pass, described through hole links to each other with chute, and the width of described chute is less than the size of described fixing frame 3, and described barb passes the chute on the substrate 1 and penetrates in the attachment hole on the clamping plate 4.
The working principle of the bolt anti-dropping apparatus that the utility model provides is as follows:
As Fig. 1 ~ shown in Figure 2, during assembling, at first the barb that arranges on the fixing frame 3 is penetrated in the attachment hole on the clamping plate 4, be that fixing frame 3 and clamping plate 4 interconnect, this moment, the cooperation of fixing frame 3 and clamping plate 4 had bigger rolling momentum; Penetrate one piece of bolt 2 then, bolt 2 passes the circular hole on fixing frame 3 and the clamping plate 4, makes both holes coaxial; Bolt 2 and fixing frame 3 are welded mutually, this moment, fixing frame 3 became one with bolt 2, and with clamping plate 4 bigger rolling momentum was arranged, but can not deviate from again; With the through hole of fixing frame 3 and bolt 2 these general alignment substrate 1 tops, slip into substrate 1 along chute, the nut of screwing on from the front at last.
In sum, the utility model is by being provided with the fixing frame that is connected with bolt and the clamping plate that are connected with fixing frame, and fixing frame and clamping plate lay respectively at the both sides of substrate, guaranteed that the nut back bolt that drops can accident not drop; Simultaneously, when the barb that arranges on the fixing frame has effectively prevented the installation nut, bolts and nuts generation transfer.
More than the utility model has been done detailed description, but the utility model is not limited to the above embodiments.All equivalences of doing according to spiritual essence of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model
