Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The utility model relates to a post preassembly screw structure of a quick assembly hinge, which comprises a support 100.

As shown in fig. 2 and 4, the holder 100 includes a base 200 and a guide post 300. In the illustrated direction, the thickness direction of the substrate 200 is oriented vertically. The guide post 300 extends upward from the upper plane of the base plate 200 in a column shape. The interior of the guide post 300 is hollow along the axial direction to form a through hole 310, the upper end of the through hole 310 is an opening of the guide post 300, and the lower end penetrates to the bottom surface of the base plate 200. The upper end of the guide post 300 is used as an entering end when the screw 110 is installed, and the screw 110 coaxially penetrates through the through hole site 310. The base 200 is provided with a buckle 210, and the buckle 210 is used for being matched with the connecting seat 410 of the hinge 400 to fix and clamp, and the support 100 is fixedly installed on the hinge 400 through the buckle 210. As shown in fig. 1 and 3, a part of the structure of the hinge is shown. In actual use, after the stand 100 is mounted on the connection base 410, the through hole 310 is coaxial with the hole of the screw 110 at the rear position of the hinge 400. The screw 110 is pre-installed on the installation site. When the hinge 400 is installed, the screw 110 is rotated, and the screw 110 is coaxially screwed along the through hole 310 and passes through the screw 110 hole at the rear position of the hinge 400, so that the screw 110 is prevented from being deflected when being matched with the screw 110 hole. The assembly process guides the installation of the screw 110 through the support 100, so that the screw 110 is quickly aligned and connected with the screw 110 hole; the whole structure is simple, the screws 110 are preassembled and guided, and the installation efficiency and the accuracy of the hinge 400 are greatly improved.

In some embodiments of the present utility model, as shown in FIG. 2, a tapered ramp 320 is provided inside the entry end (upper end in the illustration) of the guide post 300. The tapered ramp 320 has a tapered shape with a large top and a small bottom. The tapered ramp 320 can assist in placement of the screw 110 into the through hole site 310, maintaining the coaxiality of the screw 110 with the through hole site 310 during rotation of the screw 110.

In some embodiments of the present utility model, guide post 300 is formed of at least two annular walls 330. Adjacent annular walls 330 have a spacing therebetween, which is a first gap 331 extending in an axial direction. In this embodiment, as shown in fig. 2 and 4, the guide post 300 is exemplified as being constituted by two annular walls 330. Both of the annular walls 330 extend upward from the upper end surface of the base plate 200. Each annular wall 330 is semi-annular, and two annular walls 330 form a cylindrical structure. Two first gaps 331 are formed between the two annular walls 330. The first gap 331 is provided with a joining wall 332, the joining wall 332 separates the first gap 331 into upper and lower parts, and the joining wall 332 connects opposite sidewalls of the annular wall 330. The first gap 331 is configured to enable outward swinging between the annular walls 330, i.e., the guide post 300 is capable of expanding outward under the action of the screw 110. The engagement wall 332 has a certain tensile force on the adjacent annular wall 330, so that the gradual stable expansion of the guide post 300 in the downward screwing process of the screw 110 can be improved, and the coaxiality of the screw 110 and the screw 110 hole during initial butt joint is ensured. As the screw 110 continues to be screwed in, the upper portion of the guide post 300 expands first and then the engagement wall 332 can be broken, at which point the screw 110 is driven smoothly into the screw 110 hole. The substrate 200 is provided with a through groove 220, the through groove 220 communicates the upper plane and the lower plane of the substrate 200, one end of the through groove 220 is communicated with the lower end of the first gap 331, and the first gap 331 and the through groove 220 form L-shaped distribution. The communication between the through slot 220 and the first gap 331 facilitates demolding during manufacture, and increases the expansion space at the connection position of the guide post 300 and the base plate 200, so that scraps generated when the connecting wall 332 is disconnected can fall into the through slot 220, and the installation of the screw 110 is prevented from being influenced by the scraps.

In some embodiments of the present utility model, as shown in fig. 2 and 4, the guide post 300 extends upward from the upper plane of the base plate 200, the lower plane of the base plate 200 is a surface away from the entry end of the guide post 300, and the clip 210 extends downward from the lower plane (bottom surface) of the base plate 200. The buckle 210 may be in a hook structure, the support 100 is made of plastic, and the buckle 210 has a certain elasticity according to its material property. In this embodiment, the left and right sides of the lower plane of the substrate 200 are symmetrically provided with the hooks 210, and the hooks of the hooks 210 deviate from each other. Specifically, as shown in fig. 1, in the direction of illustration, a rectangular mounting opening 411 is formed in the connection seat 410 of the hinge 400. Hinge plates 412 extend upward from the left and right edges of the mounting opening 411. Hinge plate 412 is used to hinge with other components of hinge 400. The mounting position of the stand 100 is located at the rear side of the mounting opening 411. The front side of the base plate 200 abuts forward against the rear edge of the hinge plate 412. The rear side edge of the hinge plate 412 is spaced from the rear side edge of the base plate 200 by a distance defined as a detent 413. After the base plate 200 abuts against the edge of the hinge plate 412, the buckle 210 is clamped down to the clamping position 413, so that the support 100 is integrally positioned and fixed on the connecting seat 410.

Wherein the base 200 and the guide post 300 are integrally injection molded on the support 100. According to the structural arrangement of the base plate 200 and the guide post 300, the whole structure is simple, and the demolding process of injection molding production is facilitated.
