Abstract

This present application concerns a boundary box for a tap that can be mounted in the wall. The boundary box comprises a housing (3) and a fixture frame (1) which is slidable mounted on the housing. The position of fixture frame can be fixed using a linkage mechanism whereby a first notch (7) on the inner side of the frame facing the housing interacts with a first rib (4) on the outer wall of the housing. The frame is provided with a passage (6) extending from the outer side of the frame to the inner side. The passage ends in the notch. The boundary box further comprises a plug (2) that can be inserted in the passage such that the plug cooperates with the rib on the housing and fixes the position of the frame relative to the housing.

Description

Technical field

This design patent is referring to a pre-mounted installation box for faucets.

State of the art

A kind of the pre-mounted installation box is circular, where the fixture frame is usually also circular. The fixture frame may be installed directly on the installation box. By means of threads on the fixture frame and the box, or alternatively by means of buckles, the fixture frame and the pre-mounted installation box can be connected tightly. During the installation, the fixture frame and installation box must be rotated about each other, which may lead to a restriction: when the installation box is non-circular, the fixture frame can not be installed.
When the installation box is non-circular, the fixture frame is usually separated into two parts, i.e. two fixture planks. The fixture plank has buckles in its inner side, which can match to the other joints on the outer wall of the installation box. Additionally, the fixture plank has plug on one end and socket on the other end. The fixture frame may be formed by connecting both fixture planks by plugging the plugs to the sockets on each other, yet the strength is reduced significantly and the connection is weakened. Due to the fixture frame is separable, when the fixture planks are under strong external force, the connection may be broken and the installation box may become unstable.

Firstly, the fixture frame is designed to have a circular structure, which is inseparable. This design not only may fix the installation box, tighten its installation, but also may simplify the installation and break the restriction of the shape of the fixture frame. Secondly, in this design patent, plugs, first ribs, second ribs along with sockets, first notches and second notches that may fit to them, are able to fix the fixture frame and the installation box into one piece tightly. At last, in this design patent, the plug is fixed by the bar-shape buckle in the fixture frame, which may tighten the connection between the fixture frame and the box body. The designed structure is concise, it not only may simplify the installation and operation of the pre-mounted installation box in the hollow wall, but also may adapt the fixture frame with a certain shape to the box body that in different shape.

Application modes

Following are detailed explanations for this design patent with the schematic drawings. It serves the technicians in this field, so that one may apply these modes according to the guideline.
As shown in Figure 1-7, this design patent introduces a pre-mounted installation box, comprising:

Circular fixture frame 1, plug 2, box body 3, first rib 4, socket 5, slot 6, first notch 7, first installation hole 8, bar-shape buckle 9, groove 10, second installation hole 11, inlet 12, outlet 13, fixture foot 14, second rib 15, vertical part 18, horizontal part 17.

The box body 3, which has a rectangular cross section, has at least one inlet 12 and outlet 13. There is one fixture foot 14, which may be used for mounting the box body 3, on each corner of the box body 3.
Several first installation holes 8 are distributed equally on the circular fixture frame 1. The linkage mechanism includes: first notch 7, slot 6, first rib 4, bar-shape buckle 9, second rib 15, plug 2, and second notch 16. First notch 7 is located on the inner side of the fixture frame 1. Slot 6, which is the hole on the end surface of the fixture frame 1, extends through the frame to the first notch 7. Additionally, Slot 6 goes through the first notch 7 and forms an extension part below the first notch 7.
