Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments:

referring to fig. 1, 2 and 6, the present embodiment discloses a shower, which includes a shower assembly, a shower assembly and a connection structure, wherein the connection structure is disposed on the shower assembly, and the shower assembly is connected to a wall connector on a wall through the connection structure, so as to fix the shower assembly on the wall. The connecting structure comprises a main body 3 and a metal insert 1 which are connected with each other, in the embodiment, the shower assembly comprises a main body 3 and a shell which is sleeved outside the main body 3, the main body 3 is made of injection molding plastic, the main body 3 is provided with a connecting port 4, in the embodiment, the main body 3 is provided with two connecting ports 4, the metal insert 1 is provided with a plug-in 11 which is used for being plugged in the wall connecting piece 2, the plug-in section 11 is plugged in the wall connecting piece 2, a locking hole 112 penetrates through the side wall of the plug-in section 11, the locking hole 112 is a threaded hole, a locking piece 5 which is used for locking the wall connecting piece 2 is arranged in the locking hole 112, in the embodiment, the locking piece 5 is an internal hexagonal headless screw, the plug-in section 11 is connected with a built-in reinforcing section 12, the connecting port 4 is provided with a cladding section 41 which is cladded inside and outside the built-in reinforcing section 12, and the cladding section 41 is cladded inside and outside the built-in the reinforcing section 12 through injection molding.

Wherein, the metal insert 1 is arranged in the injection mold when the main body 3 is injected, so that the metal insert 1 can be connected with the injection molded main body 3 into a whole when the main body 3 is injected. By arranging the built-in reinforcing section 12 on the metal insert 1, after injection molding, the cladding section 41 of the main body 3 can be cladded inside and outside the built-in reinforcing section 12, and the whole built-in reinforcing section 12 is completely embedded into the side wall of the connecting port 4, so that the connection tightness between the metal insert 1 and the main body 3 is effectively enhanced.

During the equipment, earlier with wall connection spare 2's one end pre-buried in the wall body, the other end stretches into in grafting section 11, passes locking hole 112 through locking piece 5 afterwards, screws locking piece 5 until locking piece 5 tightly supports wall connection spare 2, realizes the locking between wall connection spare 2 and the metal insert 1, makes then that the shower subassembly can be firm fixes on the wall body.

Preferably, the length of the built-in reinforcement section 12 is equal to or greater than the length of the plug section 11, so as to enhance the connection tightness between the metal insert 1 and the body 3.

Through the torque test analysis, when adopting prior art, metal thread inserts and the main part direct embedded solid of plastics material promptly, during installation locking, metal thread inserts can only bear the locking moment of torsion that is less than 3.2N.m, when exceeding this moment of torsion value, can appear the damage problem. With the connection structure of the embodiment, when the locking torque reaches 4.6N.m, the inner hexagon of the inner hexagon headless screw (as the locking piece 5) is damaged, and the product is not damaged. Therefore, the connecting structure of the embodiment can bear larger locking torque.

In this embodiment, on the one hand, through with cladding section 41 through the cladding of moulding plastics inside and outside built-in reinforced section 12, effectively increase bridging area and bridging strength between metal insert 1 and the main part 3, effectively strengthen the fastening degree of being connected between metal insert 1 and the main part 3 from this, on the other hand, reach metal insert 1 and wall connection spare 2 of the mutual grafting of locking through locking hole 112 and the locking piece 5 that set up in grafting section 11, moment of torsion effort directly acts on metal insert 1 during the installation, product simple structure, can bear bigger locking moment of torsion during the installation, and can effectively avoid product spare part fracture to appear, damaged scheduling problem, overall structure is firm.
