Description
Technical Field
The utility model relates to a connecting piece field, concretely relates to threaded fastener with supplementary block connection structure.
Background
Threaded fasteners, which are a generic term for threaded members such as nuts and bolts, are a very common type of connection in mechanical design. Traditional bolt and nut cooperation fastener when installing on the great machinery of vibration, appears not hard up phenomenon very easily after long-time operation, is because the restriction of area is connected on the one hand, and on the other hand seems not enough because the cooperation power of the little angle of circumference confining force can only rely on the screw thread. Therefore, how to improve the anti-loosening capability of the threaded connection is a significant issue in practical work.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides a threaded fastener with supplementary block connection structure.
The purpose of the utility model is realized by adopting the following technical scheme:
the utility model provides a threaded fastener with supplementary block connection structure, includes the screw rod and connects the nut on the screw rod soon, and the thread groove has been seted up on the upper portion of screw rod, inserts connecting stud in the thread groove soon, and connecting stud's top both sides rigid coupling respectively have an L type pole, and the bottom side rigid coupling of L type pole has the arc elastic metal piece of evagination, and in the rectangular channel that the nut was seted up was inserted to L type pole end, the arc wall that is used for block arc elastic metal piece was seted up to the lateral wall of rectangular channel.
Has the advantages that: this fastener has effectively improved threaded connection's connection area through the cooperation of addding thread groove and connecting stud, simultaneously through the block of arc elasticity sheetmetal and arc wall, has improved holistic circumference confining force and vertical confining force, and nut and connecting stud are as a whole, and when only both take place the syntropy not hard up simultaneously, the whole just can become flexible of fastening structure, have improved fastening reliability.
Drawings
The present invention is further explained by using the drawings, but the embodiments in the drawings do not constitute any limitation to the present invention, and for those skilled in the art, other drawings can be obtained according to the following drawings without any inventive work.
Fig. 1 is a cross-sectional view of the present invention;
FIG. 2 is an isometric view of the connecting stud and L-bar;
FIG. 3 is an isometric view of the nut;
FIG. 4 is an isometric view of the screw;
fig. 5 is a shape view of an arc-shaped groove.
Detailed Description
The invention will be further described with reference to the following examples.
Referring to fig. 1-5, taking fastening the component a to the base B as an example, the threaded fastener with the auxiliary fastening connection structure of the present embodiment includes a screw rod 1 and a nut 2 screwed on the screw rod 1, a thread groove 3 is formed on the upper portion of the screw rod 1, a connecting stud 4 is screwed into the thread groove 3, two sides of the top end of the connecting stud 4 are respectively and fixedly connected with an L-shaped rod 5, a convex arc-shaped elastic metal sheet 6 is fixedly connected to the bottom side of the L-shaped rod 5, the end of the L-shaped rod 5 is inserted into a rectangular groove 7 formed in the nut 2, and an arc-shaped groove 8 for fastening the arc-shaped elastic metal sheet 6 is formed in the side wall of the rectangular groove 7.
The depth setting of the thread groove 3 should satisfy: when the bottom surface of the nut 2 contacts the upper end surface of the part A, the distance between the bottom end of the connecting stud 4 and the bottom wall of the thread groove 3 is not less than 5 mm. The component A and the base B are provided with a first threaded hole 9 and a second threaded hole 10 for the screw rod 1 to be screwed in.
As a further preferred option, the vertical bar part of the L-shaped bar 5 is rectangular in cross-section.
As a further preferable scheme, the arc-shaped elastic metal sheet 6 is made of chromium-manganese-molybdenum steel, and the thickness is 8mm-15 mm.
Preferably, the screw 1, the nut 2, the connecting stud 4 and the L-shaped rod 5 are all made of stainless steel.
As a further preferred option, the depth of the rectangular groove 7 is half the height of the nut.
As a further preferred scheme, the nut 2 is a hexagonal nut.
The working principle is as follows: during the use, at first screw 1 is in first screw hole 9 and second screw hole 10 with the screw of screwing into as shown in fig. 1, then with two L type poles 5 hard insert in rectangular channel 7 slightly for arc elasticity sheetmetal 6 block goes into in arc wall 8, then with nut 2 and connecting stud 4 as an organic whole screwed on screw 1: the nut 2 is screwed on the screw rod 1, and the connecting stud 4 is screwed into the thread groove 3 until the bottom surface of the nut 2 contacts and presses the upper surface of the part A.
Has the advantages that: this fastener has effectively improved threaded connection's connection area through the cooperation of addding thread groove and connecting stud, simultaneously through the block of arc elasticity sheetmetal and arc wall, has improved holistic circumference confining force and vertical confining force, and nut and connecting stud are as a whole, and when only both take place the syntropy not hard up simultaneously, the whole just can become flexible of fastening structure, have improved fastening reliability.
Each single component itself, and software, control and other programs that may be involved in the present invention are market standard components or the prior art that can be obtained by those skilled in the art through technical manuals and common general knowledge, and do not affect the technical effect to be obtained.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
