Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application are further described below with reference to the accompanying drawings and examples.

Referring to the drawing figures 1-11, a first tensioning part and a second tensioning part of a hook body structure are formed on two side edges of a frame upright post, and the first tensioning part and the second tensioning part are mutually embedded and sleeved.

In order to improve the strength of the currently formed upright post, the present application designs a pin, as shown in fig. 4, the pin 1 contacts with the outer surface of the first tensioning portion in a rolling extrusion state, and drives the first tensioning portion to deform and embed into the second tensioning portion. The concrete operation is as shown in fig. 5, the space between the nailing pins 1 is assembled on the nailing wheel, the upright post is formed in a state of continuous movement, the nailing wheel synchronously rotates and drives the space between the nailing pins 1 to be pressed into the first tensioning part of the upright post, and the structural surfaces of the first tensioning part and the second tensioning part are mutually clung, so that after the nailing wheel 1 is rolled into the first tensioning part, the deformation of the first tensioning part can act on the second tensioning part, the deformation structures of the first tensioning part and the second tensioning part are mutually embedded to form an integral connection structure, the tightness of the first tensioning part and the second tensioning part is finally improved, and the problem that external force is separated is solved.

Specifically, as shown in fig. 4, the injection nail 1 includes a rod body 11, one end of the rod body 11 is provided with a conical tip 12, and the conical tip 12 can drive the first tensioning portion to deform and continuously embed the deformed structure portion into the second tensioning portion through the external force of rolling the nailing wheel, so that the two are embedded and connected, and the matching tightness is improved.

Further, as shown in fig. 4 and 7 to 9, the tapered tip 12 includes a first tapered portion 12a and a second tapered portion 12b in this order from the rod 11 toward the outside, and the second tapered portion 12b has a taper smaller than that of the first tapered portion 12a. The second cone portion 12b with smaller taper is more sharp relative to the appearance structure of the first cone portion 12a, so that the second cone portion 12b can be smoothly and rapidly rolled into the first tensioning portion and the second tensioning portion (sequentially pass through the first plate surface, the second bending surface and the first bending surface), the first plate surface is embedded into the second bending surface after being rolled and deformed through the cone center 12, the second bending surface is embedded into the first bending surface after being rolled and deformed, and therefore external force deformation mutual embedding of the first tensioning portion and the second tensioning portion is achieved, the first tensioning portion and the second tensioning portion are connected into an integrated structure, and the matched tightness is improved.

The nailing nail 1 is penetrated on the peripheral surface of the nailing wheel through the spacing of the rod bodies 11, the nailing needle 1 is fixed on the side edge of the nailing wheel through the contact of the fastening bolt and the side wall of the rod bodies 11, and meanwhile, the height of the nailing needle 1 is convenient to adjust and replace. Since the circumferential surface of the rod body 11 is a smooth surface, a reverse force is generated when the rod body is rolled into the upright post, so that the nailing needle 1 cannot be ensured to slide, and each nailing needle 1 can be rolled into the first bending surface of the first tensioning part, and thus, the position fastening performance of the nailing needle 1 is improved, the problem that the effective rolling depth cannot be ensured due to the sliding caused by overcoming the reverse force of the upright post is solved, and as shown in fig. 4 and 11, a position adjusting inclined surface 11a facing the bottom end direction of the nailing needle is formed on the side wall of the rod body 11. The fastening bolt of the nailing wheel contacts the inclined surface, and when the nailing needle 1 is subjected to the reverse acting force of the upright post, the adjusting inclined surface 11a can limit the movement of the nailing needle 1, thereby ensuring the position accuracy of the nailing needle and overcoming the reverse acting force of the upright post.

The principle of the application is as follows: the nailing needle is assembled on the peripheral surface of the nailing wheel, the nailing wheel synchronously rotates in the moving process of the stand column, the conical center 12 of the nailing needle 1 is driven to sequentially pass through the first plate surface, the second bending surface and the first bending surface of the stand column, the first plate surface is embedded into the second bending surface after being rolled into deformation through the conical center 12, the second bending surface is embedded into the first bending surface after being rolled into deformation, and therefore the mutual embedding of the external force deformation of the first tensioning part and the second tensioning part is realized, the first plate surface, the second plate surface and the second bending surface are connected into an integrated structure, the matched tightness is improved, and finally the integral strength of the stand column is improved.

The foregoing has outlined and described the basic principles, main features and advantages of the present application. Various changes and modifications may be made to the present application without departing from the spirit and scope of the application, and such changes and modifications fall within the scope of the application as hereinafter claimed.
