Description
Technical Field
The present disclosure relates to mounting structures for embedded nuts, and particularly to a mounting structure for an elastic embedded nut.
Background
The embedded nut is widely applied to automobile manufacturing, such as automobile body outer plate connection, chassis component assembly, engine part fixation, instrument panel installation and the like. The second procedure can be reduced by embedding the nut, and the assembly process is simplified. The embedded nut is compact in structure and convenient to use, but the interference between the embedded nut and the mounting seat needs to be controlled in the specific use process, the connection strength is unstable when the interference is too small, and the mounting seat is extruded when the interference is too large, so that the possibility of damage is caused.
For example, chinese patent specification CN214533871U discloses a fastening connection structure with an embedded self-locking nut, comprising an embedded self-locking nut and a bolt; the base body is provided with a mounting hole at the joint, the embedded self-locking nut is arranged in the mounting hole, and the bolt penetrates through the part and is fixedly connected with the embedded self-locking nut; the mounting hole is a special-shaped hole, the embedded self-locking nut is circular, the size of the embedded self-locking nut is larger than the radial minimum size of the mounting hole, and when the embedded self-locking nut is mounted in the mounting hole, the embedded self-locking nut is extruded by the mounting hole to generate certain deformation.
The above proposal forms locking by making the two shapes of the mounting hole and the embedded nut different so as to generate elastic deformation after the embedded nut is mounted. However, the above scheme has the following disadvantages: because the embedded nut is wholly immersed in the mounting seat, namely, the matrix is locked, larger deformation force can be generated on the periphery of the mounting hole on the mounting seat, and the mounting seat is easy to deform and damage.
Disclosure of Invention
The utility model provides an elastic embedded nut mounting structure which reduces deformation force generated after the embedded nut is mounted on the premise of ensuring connection stability.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the mounting structure of the elastic embedded nut comprises a mounting seat and the embedded nut, wherein the mounting seat comprises a mounting hole, the embedded nut comprises elastic pins which are symmetrically arranged, the pins comprise expansion parts and first deformation parts, the two expansion parts are in parallel relation, and the distance between the two expansion parts is larger than the aperture of the mounting hole; after the pins pass through the mounting holes, the parts outside the mounting holes are expanded towards the opposite directions under the drive of the first deformation parts.
The beneficial effects of the utility model are as follows: because the hole diameter of the mounting hole is larger between the expansion parts, the elastic pin can elastically deform after entering the mounting hole, so that the pin is abutted in the mounting hole, and the fixation of the embedded nut is realized; more importantly, after the first deformation part is additionally arranged, the space between the expansion parts which can be originally reduced can be enlarged, so that the expansion parts turn over towards the outer direction of the aperture of the mounting hole, the embedded nut can be more stably connected with the mounting seat due to the fact that the expansion parts located outside the mounting hole turn over, and the deformation force generated after the embedded nut is mounted can be reduced due to the fact that the expansion parts located outside the mounting hole are more difficult to loose.
Further, the pin further comprises a second deformation portion which is connected with the expansion portion and is opposite to the expansion portion, the first deformation portion is arranged on the second deformation portion, and at least one part of the first deformation portion is located outside the pin and enables the two second deformation portions to generate a trend deviating from each other when the first deformation portion passes through the mounting hole.
After the second deformation part is connected with the expansion part, two symmetrically arranged pins form a clamping jaw shape, when the pins are embedded into the mounting holes, the first deformation part outside the pins is stressed and deformed first, so that the second deformation part is driven to deflect in the same direction as the embedding direction, and after part of the expansion part is moved out of the mounting holes, the second deformation part is driven to deflect towards the outer direction of the aperture of the mounting holes.
Further, the second deformation portion is U-shaped, two sides of the second deformation portion are connected to the expansion portion located on the same side, the first deformation portion extends out of an opening formed in the second deformation portion, and the width of the first deformation portion is smaller than that of the second deformation portion and the expansion portion.
The second deformation portion is U-shaped, and two side edges of the second deformation portion are connected to the end face of the same-side expansion portion, so that the second deformation portion can turn over with one end of the expansion portion as an axis in the process of inserting pins into the mounting holes, and the expansion portion is driven to deflect towards the outer side of the aperture of the mounting holes when the expansion portion moves out of the mounting holes. And the width of the first deformation part is smaller than that of the second deformation part and the expansion part, so that the second deformation part and the expansion part can be elastically deformed more easily after entering the mounting hole.
Further, the portion of the first deformation portion located outside the pin is inclined, and an included angle between the inclined angle and the embedding direction of the pin is larger than 90 degrees.
The first deformation part outside the pin is inclined and provided with the mounting hole, so that the deformation of the first deformation part can be further improved after the first deformation part enters the mounting hole, and the second deformation part can be driven to deflect better.
Further, the embedded nut further comprises a locking surface, a threaded hole and a plurality of locking pieces are arranged on the locking surface, and the locking pieces are matched with the mounting seat for locking after extending from the end face of the locking surface in the axial direction.
The screw hole is located the center of locking face and is used for realizing the cooperation between fastener after embedded nut installs to the setting up of locking piece can further improve the connection stability between embedded nut and the mount pad after the installation, prevents that it from deviating from.
Further, the locking piece is hook-shaped and the bending direction of the locking piece is towards the mounting seat, a locking groove is formed in the mounting seat corresponding to the locking piece, and the locking groove is gradually reduced from the opening of the locking groove towards the bottom of the groove.
The embedded nut is further fixed on the locking surface through the matching of the locking piece and the locking groove, and the locking groove is gradually tapered from the opening of the locking groove towards the groove bottom, namely the sectional area of the locking groove is gradually reduced, so that the embedded nut is clamped and fixed with the hook-shaped locking piece, and the stability of fixation is further improved.
