Problems solved by technology

At least two or more fittings are required on each tread, usually four, with at least three screw holes on each fitting, so this type of connection is particularly inefficient
[0010] At the same time, since the two inner surfaces of the fitting body and the screw rod of the screw are both smooth, during use, the relative position between the fitting body and the screw will be affected by factors such as vibration or external forces from various directions. The change makes the connection part loose, which directly affects the firmness of the connection between the tread plate and the vertical plate or the beam plate, thus leaving a safety hazard in the use of stairs

Embodiment 1

[0062] when using as Figure 12 , Figure 13 For the cap screw 2 shown in , the axial outer surface of the accessory body 1 is a toothed surface 12, and the positioning section 21 of the screw 2 includes a screw head 21a and a screw shaft 21b; the special-shaped groove 11 on the accessory body 1 by such as Figure 3-6 The shown opening groove 11a is combined with a circular positioning groove 11b, and the positioning groove 11b is integrally connected with the opening groove 11a. The screw head 21 a and the screw shaft 21 b on the screw positioning section 21 can enter through the opening groove 11 a, and are positioned and connected in the circular positioning groove 11 b on the accessory body 1 . When dismounting, the positioning section 21 of the screw is still withdrawn from the opening groove 11a.

[0063] At least one notch that can be opened and closed appropriately as shown in the figure can be provided on the circular positioning groove 11b, which is conducive to t...

Embodiment 2

[0066] when using as Figure 11 For the headless screw 2 shown, the axial outer surface of the accessory body 1 is a toothed surface 12, and the positioning section 21 of the screw 2 only includes the screw rod 21b; the special-shaped groove 11 on the accessory body 1 also includes the following Figure 3-6 The shown integrally connected opening groove 11a and a circular positioning groove 11b for positioning connection, the screw rod 21b enters or exits from the opening groove 11a;

[0067] Similarly, at least one notch that can be properly opened and closed can be provided on the circular positioning groove 11b, which is conducive to the expansion of the accessory body 1 along its radial direction; the center of the circular groove 11b coincides with the center of the accessory body 1, which is convenient for assembly quick positioning.

[0068] The setting of the screw connection section 22 is the same as that in Embodiment 1.

Embodiment 3

[0070] when using as Figure 7 or Figure 8 In the case of the accessory body 1 shown, its axial outer surface is a toothed surface 12, and the positioning section 21 of the screw 2 only includes the screw rod 21b;

[0071] The special-shaped groove 11 on the accessory body 1 is only a circular positioning groove 11 b for positioning and connection, and the circular positioning groove 11 b is centrally arranged on the top surface of the accessory body 1 . Once it needs to be disassembled, the positioning section 21 of the screw 2 can be rotated out of the circular positioning groove 11b.

[0072] The setting of the screw connection section 22 can also be the same as that in Embodiment 1.

Abstract

The invention discloses a connection fitting of a family product, comprising a fitting body and a bolt, wherein the fitting body is embedded in a first groove, and the bolt is connected with the fitting body in a positioning mode; the bolt comprises a positioning section and a linkage section; the fitting body is provided with a heteromorphic groove used for connecting with the positioning section of the bolt; the heteromorphic groove extends vertically from the top surface to the back surface; an expansion slot which enables the wall of the heteromorphic groove and the fitting body to extend moderately along the radial direction thereof is arranged in the heteromorphic groove; the notch or the wall of the expansion slot is provided with a latch mutually meshed with the positioning section of the bolt; the axial outer surface of the fitting body can be a toothed surface or a thread surface; the overall dimension thereof is slightly bigger than the diameter of the first groove; the shape of the cross section of the first groove is matched with the appearance of the fitting body; and the linkage section of the bolt is embedded in a second groove, the external diameter of the linkage section of the bolt is bigger than that of the positioning section of the bolt, and the axial periphery of the linkage section of the bolt is slightly bigger than the toothed surface of the diameter of the second groove. The fitting body can be fixed without any screw, can be quickly assembled and has high construction efficiency and firm connection.

Description

technical field [0001] The invention belongs to the technical field of hardware fittings, and relates to a connection fitting for household products. Background technique [0002] For a long time, there are generally the following types of assembly structures for household products: [0003] 1. Directly connect and fix with iron nails. It belongs to the most traditional assembly method. With this assembly structure, countless screw heads will be left on the surface of wooden products, making the surface uneven, which is not beautiful and will affect the effect of paint. The screws will rust after a long time , is also not conducive to disassembly. [0004] 2. Use drilling screw to connect and cover. Compared with the above-mentioned iron nail connection structure, the surface flatness of this assembly structure has been improved, but the construction is time-consuming and laborious, and the work efficiency is low. Once the cover at the drilled hole is lost during use, the...
