In view of the above-mentioned deficiencies of the prior art, the present invention aims to provide a method.

In order to achieve the purpose, the utility model adopts the following technical proposal:

a bracket shell comprises a shell part and a bracket part which is integrally formed with the shell part, wherein the shell part is vertically arranged and is in a single-end closed tubular shape, and the closed end of the shell part faces downwards; the bracket part is Z-shaped and comprises a mounting plate, a turning plate and a connecting plate which are connected in sequence, and the connecting plate is connected with the top of the outer shell part.

The turning plate is perpendicular to the connecting plate and is connected with the connecting plate in an enhanced mode through the reinforcing ribs.

The mounting plate is provided with a plurality of mounting holes.

The shell part is provided with a limiting block which is positioned at the bottom of the connecting plate.

A plurality of bulges are arranged on the bottom surface of the limiting block in an array manner.

The shell part is provided with a circular groove.

The float liquid level switch using the bracket shell comprises a reed switch and a float, wherein the reed switch is arranged inside the shell part, the reed switch is externally connected with a lead, and the shell is filled and encapsulated by resin; the floater is annular, the inner side surface of the floater is provided with a permanent magnet, the shell penetrates through the floater, and the permanent magnet on the inner side surface of the floater cooperates with a reed pipe in the shell part to act.

Has the advantages that:

compared with the prior art, the utility model, because the outer shell part and the bracket part are integrally formed, the assembly procedure of the outer shell part and the bracket part is omitted, thereby eliminating the use of parts such as nuts, gaskets and the like, reducing the material cost and the processing cost, reducing the installation process of the nuts and the gaskets and improving the production efficiency; therefore, the supervision problem caused by the installation of the nut and the gasket is solved, and the reject ratio of the finished product caused by the process is correspondingly reduced. Therefore, the liquid level switch using the bracket shell can be quickly installed on a washing machine or an automobile cooling water tank through the bracket part to realize the liquid level detection function.

Detailed Description

The utility model provides a support shell and use float liquid level switch of this support shell, for making the utility model discloses a purpose, technical scheme and effect are clearer, make clear and definite, and it is right that the following refers to the drawing and the embodiment is lifted the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention.

Referring to fig. 1 and 2, the present invention provides a stent shell, which includes a shell portion 1 and a stent portion 2 integrally formed with the shell portion, wherein the shell portion 1 is vertically disposed and is designed as a single-end closed tubular shape, and a closed end of the shell portion 1 faces downward; the bracket part is Z-shaped and comprises a mounting plate 2.1, a turning plate 2.2 and a connecting plate 2.3 which are connected in sequence, wherein the connecting plate 2.3 is connected with the top of the outer shell part 1. The support shell is preferably formed by plastic injection molding, so that the production and the manufacturing are convenient, and the mass production efficiency is high.

Specifically, the turning plate 2.2 is perpendicular to the connecting plate 2.3, and the turning plate 2.2 is connected with the connecting plate 2.3 through a reinforcing rib 2.5 in a reinforcing manner. Through setting up the strengthening rib, can strengthen the structural strength of support portion.

Preferably, a plurality of mounting holes 2.4 are arranged on the mounting plate. In actual assembly, pass the mounting hole and twist the screw on the product (like washing machine, car cooling water jar) through the screw and lock, easy operation is convenient, and the suitability is good.

In order to avoid that the float breaks away from the housing part in actual operation, said housing part is provided with a stop 3, which is located at the bottom of the connection plate. The float can be limited from sliding on the housing by the limiting block.

Preferably, a plurality of protrusions 4 are arrayed on the bottom surface of the limiting block. Through setting up like this, the area of contact of arch and float is little, so solve the condition emergence of float and stopper adhesion to avoid the float adhesion and the malfunction that produces.

The shell part is provided with a circular groove 5. In order to limit the distance of the downward movement of the float, the lower end of the housing part is provided with a limit ring 8 which is clamped and fixed in the circular groove.
