[0005] A lateral positioning groove is provided on the inner side surface of the external fixed cover shell on the assembly surface of the detachable bottom support seat, and the detachable bottom support seat is snap-fitted with the external fixed cover shell by snapping into the inside of the lateral positioning groove.

[0006] The outer oblique bottom surface of the external fixed cover shell is provided with a bottom assembly base protruding downward.

[0007] An arc-shaped top sinking groove is provided on the upper surface of the detachable bottom support seat.

[0008] An internal support ring is installed inside the arc-shaped top sinking groove on the upper surface of the detachable bottom support seat.

[0009] A pressure sensor controller is mounted on the inner bottom surface of the arc-shaped top sinking groove.

[0010] The beneficial effects of the utility model are:

[0011] (1) The anti-falling iron shell of the long water outlet of the utility model adopts a split structural design. During use, the detachable bottom support seat effectively supports the internal brick body to prevent the brick body from sinking, thereby improving durability and stability;

[0012] (2) By adopting a detachable bottom support seat design, it can be adapted to different internal brick structures to improve the scope of application;

[0013] (3) By adopting the transverse and longitudinal assembly methods, the lateral and bottom support of the detachable bottom support seat can be ensured, and the structural firmness and safety of the detachable bottom support seat can be ensured;

[0014] (4) The use of local and annular support designs can ensure limit stability and diversity of support methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] Figure 1 It is a structural schematic diagram of the utility model.

[0017] Figure 2 It is a schematic diagram of the internal structure of the utility model. DETAILED DESCRIPTION

[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Figure 1 and Figure 2 The long water outlet anti-falling iron shell shown includes a top iron shell body installed at the upper opening position of the long water outlet, and the top iron shell body includes an external fixed cover shell 1 and an upper fixed cover cover 2 installed at the upper opening position of the external fixed cover shell 1. A detachable bottom support seat 3 is installed on the inner side surface of the external fixed cover shell 1 between the vertical surface and the inclined support surface connection end, and external assembly through holes for internally installing locking bolts 4 are provided on the outer arc surface and the inclined bottom surface of the external fixed cover shell 1, and an internal threaded assembly blind hole matching the external assembly through hole is provided on the assembly surface of the detachable bottom support seat 3.

[0021] In order to improve the inner installation firmness, a lateral positioning groove 5 is opened on the inner side of the external fixed cover shell 1 on the assembly surface of the detachable bottom support seat 3, and the detachable bottom support seat 3 is connected with the external fixed cover shell 1 by being inserted into the lateral positioning groove 5.

[0022] In order to improve the installation firmness and stability of the locking bolt 4 located on the bottom side, a bottom assembly base 6 protruding downward is provided on the outer inclined bottom surface of the outer fixing cover 1 .

[0023] In order to facilitate top assembly, an arc-shaped top sinking groove 7 is provided on the upper surface of the detachable bottom support seat 3 .

[0024] In order to perform bottom support in different ways, an internal support ring 8 is installed inside the arc-shaped top sinking groove 7 on the upper surface of the detachable bottom support seat 3.

[0025] In order to ensure the assembly stability of the internal support ring 8 , a pressure sensor controller 9 is installed on the inner bottom surface of the arc-shaped top sinking groove 7 .

[0026] The pressure sensor controller 9 is a prior art, which detects the height of the detachable bottom support seat 3 at all positions, thereby ensuring that the height of the surrounding detachable bottom support seats 3 is monitored. When the pressure is inconsistent, the pressure sensor controller 9 will start the alarm in the prior art fixed on the outside of the external fixed cover 1, thereby issuing an audible and visual alarm. Alarms are installed on the outside of different pressure sensor controllers 9, so that the position where the pressure decreases can be more intuitively displayed.

[0027] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
