In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0029] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0030] Reference Figure 1-5 , Figure 1 It is a schematic diagram of the structure of a sprinkler nozzle of some embodiments of the utility model; Figure 2 It is a structural schematic diagram of the connection of some embodiments of the utility model; Figure 3 This is a schematic diagram of the structure of the rubber strip connection of some embodiments of the utility model; Figure 4 It is a schematic diagram of the structure of the shock absorbing member of some embodiments of the utility model; Figure 5 It is a top view of the rubber strips of some embodiments of the utility model.

[0031] The utility model provides an anti-freezing sprinkler head, comprising a sprinkler head body 1, an outer wall of a top connection 11 of the sprinkler head body 1 is provided with an external thread 12, an antifreezing pipe 2 is arranged in the connection 11, and the antifreezing pipe 2 comprises a rubber strip 21, the rubber strip 21 is directly provided with a metal arc plate 22, and the metal arc plate 22 and the rubber strip 21 are connected to form the antifreezing pipe 2.

[0032] In a low temperature environment, the water in the pipe will freeze, causing internal expansion, and the expansion in the antifreeze pipe 2 can increase the strength of the pipe at the connection 11. At the same time, the metal arc plate 22 is connected to the rubber strip 21, so that the rubber strip 21 can be stretched to a certain extent during expansion, and the compression deformation increases the volume in the pipe. At the same time, the metal arc plate 22 can increase the strength of the connection 11, which will not make the connection easy to rupture. Alternatively, a certain gap can be set between the antifreeze pipe 2 and the connection 11 for better expansion. The two metal arc plates 22 connect it to the inner wall of the connection 11 and fix it, leaving a certain gap.

[0033] According to some embodiments of the utility model, optionally, the rubber strip 21 has connecting grooves 23 on both sides, and the metal arc plate 22 has a connecting portion 24 matching the connecting grooves 23. In this way, the connection grooves 23 can be arranged to make them firmly connected, and then they can be firmly and tightly connected by adhesives, etc., so as not to separate.

[0034] According to some embodiments of the present invention, the connection groove 23 is optionally T-shaped so that the rubber strip 21 can be well connected and stuck with the metal arc plate 22 and not easily separated.

[0035] According to some embodiments of the utility model, the end surface of the rubber strip 21 is optionally wavy. When freezing, it can have a certain degree of ductility, allowing the internal space to expand to a certain extent. If a certain gap is left between the antifreeze pipe 2 and the connection 11, it can have good expansibility.

[0036] According to some embodiments of the utility model, optionally, a rubber pad 3 is provided between the inner wall of the connection 11 and the antifreeze pipe 2. If the rubber pad 3 is provided, the metal arc plate 22 will expand when ice forms, and the rubber pad 3 can have good ductility under the characteristics of the rubber pad 3, so that the rubber pad 3 can be compressed and expanded, which can also protect the connection 11 from being easily broken, and the rubber pad 3 can be used for recovery when it is not frozen.

[0037] According to some embodiments of the present invention, the rubber pad 3 is optionally connected to the rubber strip 21. This ensures that the metal arc plate 22 and the rubber strip 21 have good connectivity.

[0038] According to some embodiments of the utility model, a shock absorber 4 is optionally provided between the top of the mercury tube of the sprinkler body 1 and its water outlet, and the shock absorber 4 includes a blocking plate 41, the top of the blocking plate 41 blocks the water outlet of the sprinkler body 1, a spring 42 is provided at the bottom of the blocking plate 41, a shock absorber 43 is provided at the bottom of the spring 42, and the shock absorber 43 is supported on the top of the mercury tube. In this way, when water freezes, it will also expand from the water outlet to compress the mercury tube, and when the ice extends downward, the blocking plate 41 moves downward under the action of the spring 42, which plays a buffering role and does not directly compress the mercury tube. At the same time, the shock absorber 43 is used to protect the mercury tube from being easily broken. Under normal circumstances, if the mercury tube breaks, the water in the environment without support will flush the shock absorber 4 open, which does not affect normal use.

[0039] It should be understood that the embodiments disclosed in the present invention are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features understood by ordinary technicians in the relevant field. It should also be understood that the terms used herein are only used for the purpose of describing specific embodiments and are not meant to be limiting.

[0040] The "embodiment" mentioned in the specification means that the specific features or characteristics described in conjunction with the embodiment are included in at least one embodiment of the utility model. Therefore, the phrases or "embodiment" appearing in various places throughout the specification do not necessarily refer to the same embodiment.

[0041] In addition, the described features or characteristics may be combined in one or more embodiments in any other suitable manner. In the above description, some specific details, such as thickness, quantity, etc., are provided to provide a comprehensive understanding of the embodiments of the utility model.
