Description

Cage nuts

The present invention relates to a cage nut, and in detail, a protrusion weld portion is formed at each of the lower ends of a set of bent pieces that are bent to both sides of the cage constituting the cage nut, but two spaced apart from the lower ends of one bent piece of the set of bent pieces. Two protruding welds and the other end of the bent piece constitute a protruding weld at a position biased to one side, and the protruding weld is set at the three-point position as a whole so that the flatness of the cage nut is fixed when the cage nut is fixed. Plane correction work for fitting is desired, and among the elements constituting the cage nut, the member fitted into the nut protrusion pipe of the nut part is composed of one retainer member, and the insulation of the retainer member is secured and the tension member is tensioned to the upper and lower ends, respectively. It is made up of parts to prevent noise or noise from the outside during use. The present invention relates to a cage nut for minimizing noise due to a shock absorbing effect and impact between cage nuts.

Cage nuts generally comprise a cage of a U-shaped cross section in which a collar nut is supported in a floating manner by appropriate means.

Cage nuts are manufactured in consideration of assembly tolerances so that the components of each automobile that are assembled into a finished product by combining various components are smoothly combined.

Since each component is coupled to the cage, the cage is attached to the cage nut flowing within a certain range to the fastening hole so that each component is fastened quickly. The purpose of such cage nuts is to compensate for mounting tolerances that occur between the fixed points of the body and the parts to be mounted, such as the seats of a motor or motor vehicle. For this purpose, the nut body has sufficient play in the cage.

Such a cage nut is made by combining at least four individual parts, for example, a cage forming a base panel having one side opening and a circular guide hole formed at the center thereof, and a nut part inserted into the opened side of the cage; Insulating fixture for fitting into the nut projection tube of the nut portion, and the upper position of the insulation fixing body and is fitted to the nut projection tube, after forming the locking projections by pressing the outer periphery of the upper end of the nut projection tube to form a cage nut as a whole To be configured.

However, the cage nut of such a conventional structure has a problem that the production cost is increased due to the large number of parts and the manufacturing is difficult, and when the cage nut is poor in the smoothness of the fixing part, the cage nut is kept horizontal and the cage nut is There is a problem that the plane correction operation is impossible because the welding can not be fixed.

Meanwhile, in the case of the 'electrically insulated cage nut' disclosed in Korean Patent Application Publication No. 10-2013-0036230, the 'nut body includes a cylindrical fastener and an extended fixing element, and the cylindrical fastener has a female thread and has an opening in the cage. Extends through, the inner diameter of the opening is substantially larger than the outer diameter of the cylindrical fastener but smaller than the external dimensions of the fastening element, and includes a nut body fixed in the cage, and an insulation device arranged between the cage and the cylindrical fastener, The insulating device is integrally formed so that the cage nut is disclosed as an electrically insulating cage nut consisting of only three components.

In the case of the prior patent, by reducing the number of parts of the cage nut from the previous four parts to three parts, it is true that some of the above problems are solved, but it is difficult to secure smoothness when fixing the cage nut to the vehicle body. There is a problem, and as described above, the disadvantage of not being able to reduce the noise generated during external impact or collision in the cage nut transportation process is not solved.

Noise is not only a noise generated when the cage nut is transported, but also an insulation device which is inserted into the cage after being fixed to the vehicle body and mounted on the cylindrical end of the nut body (hereinafter referred to as a nut protrusion pipe in the present invention). When the flow inside the cage has a certain amount of play, but in the case of the prior patent is to suppress the fluidity, in this case there is a problem that the playability of the nut part, that is, the nut body in the cage is greatly reduced, In case of securing the playability of the nut body, the noise caused by the left and right flow of the nut body is essentially generated when the nut body and the cage flow, and there is a problem that multiple noise is generated in the cage nut fixed in a myriad of numbers inside the vehicle body. The prior patent does not solve this problem.

Therefore, the prior patent discloses that the left and right flow of the nut body is quite limited, there is a problem that the playability of the nut body is not sufficiently secured.

In contrast, Korean Patent Application Publication No. 10-2014-0021607, filed in Korea, discloses a 'cell-centering cage nut' with a 'opening cage, and a hollow-cylindrical shoulder portion accommodated in the cage and having internal screws. And a nut body having a nut body with an extended flange, wherein a spacer element is disposed between the nut body and the cage, the element having at least one spring element acting perpendicular to the axial direction of the inner screw. It provides a cage nut, characterized in that it comprises a.

Unlike the above-mentioned prior patent [Patent Document 1], the aforementioned patent adopts a spacer element capable of sufficiently securing the playability of the nut main body, and causes a squeaking noise even when not in use when the spacer element is flowed. Provides a configuration to avoid doing so.

However, the above configuration requires a configuration of an insulator, a spring element, a spacer element, a nut part, and a cage, which is somewhat different from minimizing the number of parts. When the shaking up and down occurs, the shock is transmitted as it is, there is a problem that can not suppress the noise generated therefrom.

The present invention has been made to solve the above-described problems, such as to reduce the number of components constituting the cage nut to minimize the production price of the product, and also to move the nut in the cage nut up and down When the impact force generated during the flow is configured to be buffered to prevent the noise caused by the impact force, when the cage nut is welded fixed to the set position when the smoothness between the cage nut and the fixed part can not maintain the horizontality The purpose is to ensure the horizontality of the cage nut to be fixed in the set position by configuring a three-point protruding welding portion consisting of the lower sides of the cage to enable the correction of the welding fixing position.

The present invention for achieving the above object, the cage 100 to form a bending piece (130, 130 ') each bent in both sides of the upper plate 101 having a guide hole 120 is circular through the center and one side is opened And, in the cage nut consisting of the nut portion 200 which is inserted in the opening direction of the cage 100,

It is characterized in that the retainer 300, which is fitted to the outer circumferential surface of the nut protruding tube 210 of the nut part 200 and made of an insulator that absorbs the shock generated during the up, down, left and right flow is fixed.

According to the present invention, one of the elements constituting the cage nut is inserted into the nut projection tube of the nut portion consisting of one retainer member, but ensuring the insulation of the retainer member and the tension member is formed on the upper and lower ends of the retainer member, respectively, to be generated when not in use. It is possible to minimize the buffer effect due to noise or impact from the outside, and the noise due to the impact between cage nuts, and to reduce the production cost due to the reduction of the number of parts constituting the cage nut.
