Abstract
Description
Technical Field
[0001] The utility model belongs to the field of pipelines, and more specifically, it relates to a fire hose and a quick installation tool. Background Art
[0002] There are various installation methods for fire hoses, including threaded connection, welded connection, flange connection, socket connection, and grooved connection, etc. Among them, threaded connection is a common and important method. It mainly involves machining threads at both ends of the pipeline, and then using sealing materials (such as PTFE tape) and threaded joints to tightly connect the pipelines together to ensure the reliability and tightness of the fire protection system.
[0003] However, in the prior art, for the water pipe connection methods similar to the above, due to the relatively smooth circumferential side wall and the filling of PTFE tape at the connection, when the water pipe is rotationally connected, it is prone to problems such as slipping and insufficient force to tighten. Therefore, a new solution is needed to solve the above problems. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a fire hose and a quick installation tool, which have the advantage of facilitating the installation of the water pipe.
[0005] To achieve the above purpose, the present utility model provides the following technical solutions:
[0006] A fire hose includes a pipe body and threaded portions located at both ends of the pipe body. A plurality of convex teeth are provided on the circumferential side wall of the pipe body, and the convex teeth are distributed in a circumferential manner along the axis of the pipe body.
[0007] The advantages of this solution are at least: The convex teeth can cooperate with the notches on the quick installation tool, so that people can clamp the pipe body through a quick installation tool similar to a clamp, thereby realizing the tightening of the water pipe. Since it is through a clamping method, the problems of frictional slipping and insufficient force to tighten are avoided.
[0008] The present utility model is further provided as: A bottom ring coaxial with the pipe body is fixed at the bottom of the convex teeth on the circumferential side wall of the pipe body.
[0009] The advantages of this solution are at least: The bottom ring can cooperate with the quick installation tool to support the left half clamp and the right half clamp of the quick installation tool, thereby quickly positioning the quick installation tool and facilitating operation.
[0010] The present utility model is further provided as: Reinforcing ribs are connected between the convex teeth and the pipe body.
[0011] The advantages of this solution are at least: Improve the connection stability between the convex teeth and the pipe body.
[0012] In addition, the utility model also provides a quick installation tool for a fire hose, which includes a left half clamp and a right half clamp. One end of the left half clamp and the right half clamp is hinged, and the other end of each extends outward to be provided with a handle. The left half clamp and the right half clamp are provided with notches for the convex teeth to be inserted into.
[0013] The advantages of this solution are at least as follows: directly sleeving the major arc formed by the left half clamp and the right half clamp on the water pipe, then aligning the notch with the convex teeth and inserting them, and then manually closing the two handles can achieve clamping of the water pipe, forming a structure similar to a pair of pliers. Then rotating the handle can apply a rotational force to the water pipe, thereby achieving tightening of the water pipe. Since the connection is through the engagement of the notch and the convex teeth, the problems of friction slip and insufficient force resulting in failure to tighten are avoided.
[0014] The utility model is further configured as: the notch penetrates through the left half clamp and the right half clamp downward.
[0015] The advantages of this solution are at least as follows: after the major arc formed by the left half clamp and the right half clamp is sleeved on the water pipe, only direct downward movement is required to achieve the engagement of the notch and the convex teeth, optimizing the operation.
[0016] The utility model is further configured as: the size of the notch is larger than the size of the convex teeth.
[0017] The advantages of this solution are at least as follows: the larger-sized notch is downward compatible with the smaller-sized convex teeth, facilitating the insertion of the convex teeth into the notch.
[0018] The utility model is further configured as: at least one handle is provided with a wavy portion.
[0019] The advantages of this solution are at least as follows: on the one hand, the wavy portion is wavy, conforming to the ergonomics of the fingers; on the other hand, the wavy shape can function as an anti-slip feature.
[0020] The utility model is further configured as: the handle is provided with a rubber sleeve.
[0021] The advantages of this solution are at least as follows: the rubber sleeve can, on the one hand, improve the holding comfort, and on the other hand, reduce the problem of slipping.
[0022] In summary, the utility model has at least the following advantages:
[0023] 1. By presetting convex teeth on the pipe body and inventing a quick installation tool similar to a pair of pliers, and through the connection of the quick installation tool and the convex teeth, the problems of friction slip and insufficient force resulting in failure to tighten are avoided;
[0024] 2. By further defining that the notch penetrates through the left half clamp and the right half clamp downward, after the superior arc formed by the left half clamp and the right half clamp is sleeved on the water pipe, the notch can be directly moved downward to achieve the clamping connection with the convex teeth, which optimizes the operation.
[0025] 3. By arranging a bottom ring on the pipe body, the bottom ring can cooperate with the quick installation tool to support the left half clamp and the right half clamp of the quick installation tool, so as to quickly position the quick installation tool and facilitate the operation.

[0029] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0030] A fire fighting water pipe includes a pipe body 1 and threaded parts 2 located at both ends of the pipe body 1. A plurality of convex teeth 3 are provided on the circumferential side wall of the pipe body 1. The convex teeth 3 are integrally formed with the circumferential side wall of the pipe body 1, and the convex teeth 3 are distributed in a surrounding manner along the axis of the pipe body 1. In a preferred embodiment, there are two convex teeth 3 and they are symmetrically distributed on the outer peripheral wall of the pipe body 1. In order to improve the structural stability of the convex teeth 3, in some embodiments, a reinforcing rib (not marked in the figure) is connected between the convex teeth 3 and the pipe body 1.
[0031] In some embodiments, a bottom ring 4 coaxial with the pipe body 1 is fixed to the circumferential side wall of the pipe body 1 at the bottom of the convex teeth 3, and there is preferably a gap between the bottom ring 4 and the convex teeth 3.
[0032] In some embodiments, the present utility model provides a quick installation tool for a fire hose, which includes a left half clamp 5 and a right half clamp 6. One end of the left half clamp 5 and the right half clamp 6 is hinged, and the other end of each extends outwardly to be provided with a handle 7. The left half clamp 5 and the right half clamp 6 are provided with notches 8 for the convex teeth 3 to be inserted into. When installing the hose, the major arc formed by the left half clamp 5 and the right half clamp 6 is directly sleeved on the hose. At this time, the bottom ring 4 can play a supporting role, eliminating the operation of vertically aligning the convex teeth 3 and the notches 8. Then, align the notch 8 with the convex teeth 3 and insert them. Subsequently, manually closing the two handles 7 can clamp the hose, forming a structure similar to a pair of pliers. Then, rotating the handle 7 can apply a rotational force to the hose, thereby achieving the tightening of the hose. Since the connection is through the engagement of the notch 8 and the convex teeth 3, the problems of friction slip and insufficient force for non-tightening are avoided.
[0033] In order to simplify the operation, in some embodiments, the notch 8 is directly set to penetrate downward through the left half clamp 5 and the right half clamp 6. After the major arc formed by the left half clamp 5 and the right half clamp 6 is sleeved on the hose, only a direct downward movement is required to achieve the engagement of the notch 8 and the convex teeth 3. Preferably, the size of the notch 8 is slightly larger than the size of the convex teeth 3, thereby further facilitating the insertion of the convex teeth 3 into the notch 8.
[0034] In order to reduce the problem of the handle 7 slipping out of the hand, in some embodiments, at least one handle 7 is provided with a wavy portion 9. Of course, providing a rubber sleeve (not marked in the figure) on the handle 7 can also improve the holding comfort while reducing the slipping problem.
[0035] The working process and beneficial effects of the present utility model are as follows: The convex teeth 3 can cooperate with the notch 8 on the quick installation tool, so that people can clamp the pipe body 1 through a quick installation tool similar to a pair of pliers, thereby achieving the tightening of the hose. Since the connection is through a clamping method, the problems of friction slip and insufficient force for non-tightening are avoided.
[0036] The specific operation is as follows: When installing the hose, directly sleeve the major arc formed by the left half clamp 5 and the right half clamp 6 on the hose, then align the notch 8 with the convex teeth 3 and insert them. Subsequently, manually closing the two handles 7 can clamp the hose, forming a structure similar to a pair of pliers. Then, rotating the handle 7 can apply a rotational force to the hose, thereby achieving the tightening of the hose.
[0037] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
