Description
Technical Field
[0001] The utility model belongs to the technical field of fire fighting appliances, and particularly relates to a reciprocating water gun. Background Art
[0002] Fire is a relatively common disaster, which causes serious harm to people's lives, property and the environment. Due to the diversity and complexity of fire accidents, various types of fire fighting water guns have emerged. Among them, the backpack reciprocating fire fighting water gun has the advantages of being easy to carry and having good mobility, and plays an important role in forest fire prevention and some areas with complex terrain and environment. Generally, a reciprocating fire fighting water gun consists of a backpack water tank and a reciprocating water gun connected thereto. The reciprocating water gun is composed of a one-way water inlet pipe and a water outlet pipe that are piston-sleeved with each other. By pulling the one-way water inlet pipe or the water outlet pipe, negative pressure is generated inside to suck water, and by pushing the one-way water inlet pipe or the water outlet pipe, the water is ejected.
[0003] The Chinese utility model patent with the application number of "2009202932611" discloses a reciprocating fire fighting water gun, which includes a spraying gun head, an inner rod handle and an outer rod handle. The inner rod handle is inserted into the outer rod handle, and a water inlet communicating with an external water pipe is provided at the rear end head. An inclined handle is provided at the front part of the inner rod handle, and an inner and outer pipe locking device is sleeved on the inner rod handle behind the inclined handle. When in use, one hand holds the outer rod handle, and the other hand holds the inclined handle on the inner rod handle and pushes and pulls the inner rod handle to complete water spraying. In order to facilitate exerting force, generally, users are used to holding the part of the inclined handle close to the inner rod handle. At this time, when the reciprocating water gun moves back forcefully, the thumb of the hand holding the inclined handle is easily clamped or even injured by the inclined handle and the outer rod handle. If the length of the inner rod handle is increased to prevent pinching the hand so as to leave a gap between the inclined handle and the inner rod handle, the overall length of the water gun will increase, reducing the operation experience and also conflicting with the principle of portability of the reciprocating water gun, and the stroke of the length between the inclined handle and the inner rod handle is not fully utilized. 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 reciprocating water gun that can prevent pinching the hand and make full use of the handle stroke.
[0005] The purpose of the present utility model can be realized by the following technical solutions:
[0006] A reciprocating water gun includes an inner rod and an outer rod that are piston-sleeved with each other. The outer rod is sleeved outside the inner rod. An inclined handle is fixedly connected to the front part of the inner rod. The inclined handle includes a socket part and a hand-held part. The socket part is in the shape of a hollow tube and is sleeved outside the inner rod. The inner rod, the outer rod and the socket part are coaxially arranged. The inner diameter of the rear part of the socket part is larger than the outer diameter of the outer rod, and the outer rod can be inserted into the socket part.
[0007] When this reciprocating water gun is in use, the user holds the outer rod with one hand and the hand-held part of the inclined grip with the other hand. When holding the inner rod, the thumb is close to the rear of the socket part. Since the inner diameter of the rear of the socket part is larger than the outer diameter of the outer rod, when pulling the inner rod back forcefully to insert the outer rod into the socket part, there is no need to increase the length of the inner rod, which can avoid pinching the thumb and will not additionally increase the occupied space to affect the portability of the reciprocating water gun. In addition, if a solid limiting structure is set here to avoid pinching the hand, it will inevitably lead to a shortened stroke of the inner rod and reduce the water spraying efficiency. Therefore, through the structural design of inserting the outer rod into the socket part, this part of the stroke of inserting the outer rod into the socket part is fully utilized, and the original water spraying efficiency will not be affected.
[0008] In this reciprocating water gun, the front part of the socket part gradually tapers forward axially to match the outer diameter of the inner rod.
[0009] In order to enable the outer rod to be inserted into the socket part, the inner diameter of the socket part needs to be designed larger, which makes it easy for some sundries to enter along the gap between the socket part and the inner rod. Therefore, the front part of the socket part gradually tapers forward axially to match the outer diameter of the inner rod, so as to prevent sundries from entering through the gap between the socket part and the inner rod and affecting normal use.
[0010] In this reciprocating water gun, anti-slip patterns are provided on the hand-held part, and an anti-slip sleeve is provided on the outer rod, and anti-slip patterns are provided on the anti-slip sleeve. During the use of the water gun, it is inevitable that it will get wet and cause the hand to slip, so anti-slip components need to be set, and the anti-slip patterns play a role in increasing friction.
[0011] In this reciprocating water gun, the rear end of the outer rod is the water inlet, the front end of the inner rod is the water outlet, a water gun nozzle is provided at the position of the water outlet, and one-way water inlet components are provided at the rear ends of both the inner rod and the outer rod.
[0012] When pushing the inner rod forward, a negative pressure is formed inside the outer rod, the one-way water inlet component at the rear end of the outer rod opens, and the one-way water inlet component at the rear end of the inner rod closes, introducing water into the outer rod. Then, when pulling the inner rod back, the one-way water inlet component at the rear end of the inner rod opens, and the one-way water inlet component at the rear end of the outer rod closes, causing the water to be sprayed out through the water outlet of the inner rod.
[0013] Furthermore, the inner rod is provided with a first sealing ring with an annular protrusion. A water guiding hole radially penetrating the inner rod is provided between the first sealing ring and the one-way water inlet component. Through the sealing of the sealing ring and the one-way water inlet component, a water storage cavity is formed in the gap between the inner rod and the outer rod. While pulling the inner rod back, part of the water flows into the water storage cavity through the water guiding hole. When pushing the inner rod outward, the water in the water storage cavity enters the inner rod along the water guiding hole and is sprayed out, ensuring the continuity of the sprayed water flow.
[0014] Further, a second sealing ring is provided on the inner rod between the socket part and the first sealing ring. During the normal use of the water gun, although the first sealing ring seals the water, under the high-strength reciprocating push and pull, there will still be water seepage. Therefore, the second sealing ring is provided to further play a sealing role.
[0015] Compared with the prior art, the technical effects of the present utility model are as follows:
[0016] The outer rod of the reciprocating water gun provided by the present utility model is inserted into the socket part. Without increasing the length of the inner rod, it can avoid pinching the thumb, does not additionally increase the occupied space, and improves the operation experience; through the structural design of inserting the outer rod into the socket part, this scheme makes full use of the stroke of the outer rod inserted into the socket part and does not affect the original water spraying efficiency; the front part of the socket part of this scheme gradually tapers forward axially to match the outer diameter of the inner rod, which can prevent sundries from entering through the gap between the socket part and the inner rod and affecting the normal use.

Detailed Embodiments
[0025] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.
[0026] As Figure 1 、 Figure 2 、 Figure 3 shown, a reciprocating water gun includes an inner rod 1 and an outer rod 2 that are sleeved in a piston-like manner. The outer rod 2 is sleeved outside the inner rod 1. The front part of the inner rod 1 is fixedly connected with an inclined handle 3. The inclined handle 3 includes a socket part 31 and a handheld part 32. The socket part 31 is in the shape of a hollow tube and is sleeved outside the inner rod 1. The inner rod 1, the outer rod 2, and the socket part 31 are coaxially arranged. The front part of the socket part 31 gradually tapers forward along the axis to adapt to the outer diameter of the inner rod 1.
[0027] Furthermore, as Figure 4 shown, the inner diameter of the rear part of the socket part 31 is larger than the outer diameter of the outer rod 2. When the inner rod 1 is pulled back, the user's fingers are close to the outer peripheral surface of the socket part 31, and the outer rod 2 is inserted into the inside of the socket part 31, which not only avoids pinching the hand but also makes full use of the short-distance stroke of inserting into the socket part 31 to improve the water spraying efficiency.
[0028] Preferably, as Figure 2 、 Figure 5 shown, the handheld part 32 is provided with anti-slip lines 321, and the outer rod 2 is provided with an anti-slip sleeve 21, and the anti-slip sleeve 21 is provided with anti-slip lines. During the use of the water gun, it is inevitable to get wet, resulting in a decrease in the friction force on the outer surface of the water gun. The setting of anti-slip components can effectively prevent the water gun from slipping out of the hand during use.
[0029] Preferably, as Figure 3 、 Figure 6 shown, the rear end of the outer rod 2 is a water inlet 22, the front end of the inner rod 1 is a water outlet 11, a water gun nozzle 12 is provided at the position of the water outlet 11, and one-way water inlet assemblies 4 are provided at the rear ends of both the inner rod 1 and the outer rod 2. When the inner rod 1 is pushed forward, a negative pressure is formed inside the outer rod 2, and the one-way water inlet assembly 4 at the rear end of the outer rod 2 opens, and the one-way water inlet assembly 4 at the rear end of the inner rod 1 closes, introducing water into the outer rod 2. Then, when the inner rod 1 is pulled back, the one-way water inlet assembly 4 at the rear end of the inner rod 1 opens, and the one-way water inlet assembly 4 at the rear end of the outer rod 2 closes, causing the water to spray out through the water outlet 11 of the inner rod 1. The inner rod 1 is provided with a first sealing ring 13 with an annular protrusion, and a second sealing ring 15 is provided between the socket part 31 and the first sealing ring 13 on the inner rod 1. The double sealing effect effectively reduces the leakage of water inside the water gun.
[0030] Furthermore, as Figure 7As shown in the figure, a water diversion hole 14 radially penetrating the inner rod 1 is provided between the first sealing ring 13 and the one-way water inlet assembly 4. The gap between the inner rod 1 and the outer rod 2 forms a water storage cavity 5 due to the sealing of the sealing ring 13 and the one-way water inlet assembly 4. When the inner rod 1 is pulled back, part of the water flows into the water storage cavity 5 through the water diversion hole 14. When the inner rod 1 is pushed outwards, the water in the water storage cavity 5 enters the inner rod 1 along the water diversion hole 14 and sprays out, ensuring the continuity of the sprayed water flow.
[0031] The above embodiments are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope defined by the claims of the present invention.
