Abstract
The utility model discloses flanged surface hexagonal self-locking nut, comprise outer-hexagonal body, in outer-hexagonal body, establish tapped hole, flanged surface is established in the lower end surface of outer-hexagonal body, retaining decorative pattern and center counterbore are established in the bottom surface of flanged surface, and the cylindrical of center counterbore is the inner ring of retaining decorative pattern, it is characterized in that: the outside diameter of described center counterbore is A, outer-hexagonal body two is being just B to the distance between hexagon, more than A size is less than B size 4mm; The top part of outer-hexagonal body is provided with horizontal grooving, and laterally grooving runs through outer-hexagonal body half.The utlity model has the advantage that intensity is high, have reliable retaining and locking function simultaneously concurrently, can solve well the flanged surface problem of easy-rupturing when mounted of traditional nut of the same type.
Description
Technical field
The utility model relates to a kind of Fastener products, is specifically related to a kind of improvement invention of flanged surface hexagon nut.
background technique
In Fastener products, flanged surface hexagon nut is applied greatly on a large scale because of its simple in structure, fastening area.The common structure of flanged surface hexagon nut is: comprise outer-hexagonal body, in outer-hexagonal body, establish tapped hole, flanged surface is established in the lower end surface of outer-hexagonal body.Also there are some flanged surface hexagon nuts to establish retaining decorative pattern in the bottom surface of flanged surface, make it to there is stopping function, the bottom surface of flanged surface is provided with center counterbore in the central position of retaining decorative pattern when retaining decorative pattern is set, the cylindrical of center counterbore is the inner ring of retaining decorative pattern, and the outside diameter of center counterbore equals outer-hexagonal body two just to the distance between hexagon (this is the common design of product), and then cause flanged surface to be starkly lower than other position in the intensity at counterbore cylindrical position, center, thereby cause the fracture that often occurs flanged surface in the time that nut is tightened up, nut is directly scrapped, although can solve the problems referred to above from increasing material thickness aspect, but involve the consumption of material and the too much raising of cost, so maintain so existing project organization always, unless nut has specific intensity requirement to adopt structure thicker.Also have, the current flanged surface hexagon nut with retaining decorative pattern does not possess other locking function, because adopt nylon spacer locking, tinsel locking and screw thread distortion locking all can bring the nut increase of size and complexity of structure in short transverse, be all not too applicable to large batch of production and application.
Summary of the invention
In view of the problem of current known technology existence, the technical problems to be solved in the utility model is to be to provide a kind of to have advantages of that intensity is high, have reliable retaining and locking function concurrently simultaneously, can the fine solution flanged surface flanged surface hexagonal self-locking nut of easy-rupturing problem when mounted.
The utility model is implemented by the following technical programs:
Flanged surface hexagonal self-locking nut, comprise outer-hexagonal body, in outer-hexagonal body, establish tapped hole, flanged surface is established in the lower end surface of outer-hexagonal body, retaining decorative pattern and center counterbore are established in the bottom surface of flanged surface, and the cylindrical of center counterbore is the inner ring of retaining decorative pattern, it is characterized in that: the outside diameter of described center counterbore is A, outer-hexagonal body two is being just B to the distance between hexagon, more than A size is less than B size 4mm.The top part of outer-hexagonal body is provided with horizontal grooving, and laterally grooving runs through outer-hexagonal body half.
Adopt the flanged surface hexagonal self-locking nut of technique scheme, compared with prior art have the following advantages: 1. the cylindrical of center counterbore designs near the center of tapped hole, make the outside diameter of center counterbore be less than outer-hexagonal body two just to the distance between hexagon more than 4mm, improve the stressing conditions of flanged surface, after above-mentioned design, substantially do not increasing under the prerequisite of material consumption, can make the intensity of flanged surface improve to meet usage requirement, even flanged surface appearance distortion also can not be ruptured in the time of tightening nut, nut also can be proceeded to use; 2. the top part of hexagon is offered a horizontal grooving outside, just can make the pitch of upper and lower tapped hole change like this by the distortion of part on outer-hexagonal body, hangs the effect of drawing, thereby make nut have locking function thereby reach certain screw thread; 3. flanged surface is provided with retaining decorative pattern and makes nut have stopping function.
Brief description of the drawings
The utility model has following accompanying drawing:
Fig. 1 is bottom surface of the present utility model direction view,
Fig. 2 is the A-A view of Fig. 1,
Fig. 3 is end face direction view of the present utility model.
Embodiment
Describe details and the working principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, flanged surface hexagonal self-locking nut of the present utility model, comprise outer-hexagonal body 1, establish tapped hole 5 in outer-hexagonal body 1, flanged surface 2 is established in the lower end surface of outer-hexagonal body 1, retaining decorative pattern 3 and center counterbore 4 are established in the bottom surface of flanged surface 2, the cylindrical of center counterbore 4 is the inner ring of retaining decorative pattern 3, and the cylindrical of center counterbore 4 designs near the center of tapped hole 5, and the outside diameter of described center counterbore 4 is A, 1 liang of outer-hexagonal body is being just B to the distance between hexagon, more than A size is less than B size 4mm; The top part of outer-hexagonal body 1 is provided with a horizontal grooving 6, laterally the width of grooving 6 is in 2.5mm left and right, laterally grooving 6 is from running through in a lateral direction outer-hexagonal body 1 half, then make the top and the bottom of outer-hexagonal body produce certain amount of deformation up and down by the mode of pressing outer-hexagonal body top, so the pitch of the tapped hole of top and the bottom also changes.
Flanged surface hexagonal self-locking nut of the present utility model, the top part of hexagon is offered a horizontal grooving outside, just can make the pitch of upper and lower tapped hole change by the distortion of part on outer-hexagonal body like this, thereby nut is when mounted in the time that bolt passes the tapped hole of outer-hexagonal body top and the bottom, its screw thread will be subject to certain effect of drawing of hanging up and down, increase threads turn frictional force, thereby make nut after screwing, there is locking function.
Claims (2)
1. flanged surface hexagonal self-locking nut, comprise outer-hexagonal body, in outer-hexagonal body, establish tapped hole, flanged surface is established in the lower end surface of outer-hexagonal body, retaining decorative pattern and center counterbore are established in the bottom surface of flanged surface, and the cylindrical of center counterbore is the inner ring of retaining decorative pattern, it is characterized in that: the outside diameter of described center counterbore is A, outer-hexagonal body two is being just B to the distance between hexagon, more than A size is less than B size 4mm.
2. flanged surface hexagonal self-locking nut as claimed in claim 1, is characterized in that: the top part of outer-hexagonal body is provided with horizontal grooving, and laterally grooving runs through outer-hexagonal body half.
