Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire-fighting equipment technology, and more specifically, it relates to a fire extinguisher nozzle. Background Technology
[0002] The nozzle mounted on a fire extinguisher hangs downwards in its natural state, requiring one hand to lift the extinguisher and the other to support the nozzle while extinguishing the fire. If the nozzle did not require support during extinguishing, one hand could be freed. Therefore, this invention proposes a fire extinguisher nozzle. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fire extinguisher nozzle.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The fire extinguisher nozzle involved in this utility model includes a nozzle connection nozzle provided on the fire extinguisher body, a freely bendable nozzle body connected to the nozzle connection nozzle, and a telescopic multi-section sleeve fitted on the nozzle body. The multi-section sleeve includes at least three shaped conical tubes fitted from the inside out. The diameter of the larger end of the innermost shaped conical tube in two adjacent shaped conical tubes is larger than the diameter of the smaller end of the outermost shaped conical tube. The smaller end of the innermost shaped conical tube is fitted and fixed to the nozzle connection nozzle.
[0005] The present invention is further configured such that the length of the multi-section sleeve in its longest extended state is not greater than the length of the nozzle body.
[0006] The present invention is further configured such that the extension and retraction direction of the multi-section sleeve is perpendicular to the axis of the fire extinguisher body.
[0007] The present invention is further configured such that all the shaped tapered tubes have the same length.
[0008] The present invention is further configured such that the shaped conical tube is a plastic tube.
[0009] In summary, the present invention has the following beneficial effects: the fire extinguisher nozzle involved in the present invention, by extending the multi-section sleeve, makes the nozzle body arranged therein nearly straight even when not held in the hand, so that the fire extinguisher can be lifted with one hand to perform fire extinguishing operation, freeing up the other hand. The overall function is perfect and the practicality is strong. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the overall structure of this utility model;
[0011] Figure 2 This is a schematic diagram illustrating the structure of a multi-section sleeve in this utility model. Detailed Implementation
[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0014] Example 1
[0015] See Figure 1 and Figure 2 As shown, the fire extinguisher nozzle involved in this embodiment includes a nozzle connector 101 disposed on the fire extinguisher body 100. A freely bendable nozzle body 102 is connected to the nozzle connector 101. A telescopic multi-section sleeve 200 is sleeved on the nozzle body 102. The multi-section sleeve 200 includes at least three shaped cone tubes 201 that are fitted from the inside out. The diameter of the larger end of the innermost shaped cone tube 201 is larger than the diameter of the smaller end of the outermost shaped cone tube 201. The smaller end of the innermost shaped cone tube 201 is fitted and fixed to the nozzle connector 101.
[0016] Furthermore, the extension and retraction direction of the multi-section sleeve 200 is perpendicular to the axis of the fire extinguisher body 100.
[0017] Furthermore, all the shaped tapered tubes 201 are of equal length.
[0018] Furthermore, the shaped tapered tube 201 is a plastic tube.
[0019] In this embodiment, the multi-section sleeve 200 of the fire extinguisher is shortened when not in use, and the nozzle body 102 is lowered and close to the fire extinguisher body 100. When the fire extinguisher needs to be used for fire extinguishing, the multi-section sleeve 200 is stretched until the two adjacent fixed cone tubes 201 are tightly fitted together, so that the nozzle body 102 placed in the multi-section sleeve 200 is straightened along the sleeve, and fire extinguishing can be performed without hand support.
[0020] Example 2
[0021] See Figure 1 and Figure 2 As shown, the fire extinguisher nozzle involved in this embodiment is further configured, based on embodiment 1, such that the length of the multi-section sleeve 200 in its longest state is not greater than the length of the nozzle body 102.
[0022] In this embodiment, by setting the length of the multi-section sleeve 200 in its longest state to no greater than the length of the nozzle body 102, the opening of the multi-section sleeve 200 in its longest state is prevented from blocking the nozzle of the nozzle body 102.
[0023] The fire extinguisher nozzle involved in this utility model extends multiple sections of the sleeve, so that the nozzle body can be straight even when not held in the hand. The fire extinguisher can be lifted with one hand to extinguish the fire, freeing up the other hand. The overall function is perfect and highly practical.
[0024] Unless otherwise specified, in this utility model, terms such as "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the actual orientation or positional relationship shown. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe orientation or positional relationships in this utility model are for illustrative purposes only and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood in conjunction with the embodiments and according to the specific circumstances.
