[0001] The utility model relates to the technical field of spray pumps, in particular to a pump body and a spray pipe connection structure of a spray pump. Background Art

[0002] Recreational facilities refer to vehicles used for business purposes, operating in a closed area, and carrying tourists for entertainment. Motorboats are a common type of recreational facility for water play.

[0003] The jet pump is a fluid power pump, which is an indispensable component of the motorboat. It is installed at the bottom of the motorboat to spray water and provide power for the motorboat through the force of the water flow. A nozzle for assisting in spraying water is installed at the tail end of the jet pump. In the existing jet pump structure, the nozzle is mostly directly fixed on the jet pump body. Therefore, when the jet pump or the nozzle is damaged, the entire jet pump often needs to be replaced, resulting in increased use and maintenance costs of the jet pump. There are also some structures that detachably connect the jet pump and the nozzle, but there is a situation where the nozzle is loose during the use of the jet pump, affecting the use effect of the jet pump. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem in the prior art that most of the nozzles are directly fixed on the spray pump body. Therefore, when the spray pump or the nozzle is damaged, the entire spray pump often needs to be replaced, resulting in increased use and maintenance costs of the spray pump. There are also some structures that detachably connect the spray pump and the nozzle, but there is a defect that the nozzle becomes loose during the use of the spray pump, affecting the use effect of the spray pump. A pump body and nozzle connection structure of a spray pump is provided, and the pump body and the nozzle are detachably connected. Therefore, when the pump body or the nozzle itself is damaged, it can be disassembled and replaced independently without replacing the entire structure, thereby reducing the maintenance and use costs of the device, and through the mutual fitting action of the inner layer fitting part and the outer layer fitting part, the pump body and the nozzle can be made more stable when connected.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model discloses a pump body and nozzle connection structure of a spray pump, which is used to connect the pump body and the nozzle. The connection position of the pump body and the nozzle is detachably connected by a locking piece. The front end of the pump body is provided with an inner sleeve part, and the tail end of the nozzle is provided with an outer sleeve part adapted to the inner sleeve part. When the pump body is connected to the nozzle, the inner sleeve part is sleeved in the outer sleeve part, and the outer wall of the outer sleeve part is provided with an assembly groove. The locking piece is movably engaged in the assembly groove, and the locking piece can slide in the assembly groove. The locking piece has two states through sliding. They are: a locked state in which one end of the locking member pins the pump body, and an unlocked state in which one end of the locking member is separated from the pump body. Such a structural arrangement allows a detachable connection between the pump body and the nozzle. Therefore, when the pump body or the nozzle itself is damaged, it can be disassembled and replaced independently without replacing the entire structure, thereby reducing the maintenance and use costs of the device. In addition, through the mutual fitting of the inner sleeve portion and the outer sleeve portion, the pump body and the nozzle can be made more stable when connected.

[0010] Preferably, a bayonet is provided on the inner side of the connecting female end along the circumferential direction, and the position of the bayonet corresponds to the position of the assembly groove. When one end of the locking component is slidably inserted into the inner position of the bayonet, the locking component enters a locked state. When one end of the locking component is slid out to the inner position of the bayonet, the locking component is in an unlocked state. Such a structural arrangement enables the locking of the locking component only through the Huadong locking component, and the operation is convenient and quick.

[0011] Preferably, a positioning plate is provided on the outer wall of the pump body at one side of the connecting female end. When the locking piece is in a locked state, a positioning bolt is inserted into the positioning plate and passes through the locking piece, thereby fixing the locking piece and ensuring that the locking piece will not loosen and fall off due to the operation vibration of the pump body.

[0012] Preferably, a pump body mounting plate is provided on the outer wall of the rear end of the pump body, and a rib plate is integrally formed on the main body mounting plate, and the rib plate is connected to the connecting female end, so that the pump body mounting plate, the rib plate and the connecting female end are integrated into one, thereby improving the overall structural strength and toughness.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The pump body and the nozzle are detachably connected, so when the pump body or the nozzle itself is damaged, it can be disassembled and replaced independently without replacing the entire structure, thereby reducing the maintenance and use costs of the device, and the mutual sheathing of the inner layer sheathing part and the outer layer sheathing part can make the pump body and the nozzle more stable when connected, and the locking effect of the locking piece can further ensure the stability of the nozzle after installation;

[0015] In the connection structure of the pump body and the nozzle, a bayonet is opened on the inner side of the connecting female end along the circumferential direction, and the position of the bayonet corresponds to the position of the assembly groove. When one end of the locking piece is slid into the internal position of the bayonet, the locking piece enters a locked state. When one end of the locking piece is slid out to the internal position of the bayonet, the locking piece is in an unlocked state. Such a structural setting makes it possible to lock the locking piece only through the Huadong locking piece, which is convenient and quick to operate. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, when the spray pump or the nozzle is damaged, the entire spray pump often needs to be replaced, resulting in an increase in the use and maintenance costs of the spray pump. There are also some structures that detachably connect the spray pump and the nozzle, but there is a defect that the nozzle becomes loose during the use of the spray pump, which affects the use effect of the spray pump. The pump body and the nozzle are detachably connected, so when the pump body or the nozzle itself is damaged, it can be disassembled and replaced independently without replacing the entire structure, thereby reducing the maintenance and use costs of the device, and through the mutual sleeve action of the inner sleeve part and the outer sleeve part, the pump body and the nozzle can be made more stable when connected. The pump body and nozzle connection structure of a spray pump of the utility model is not limited to the description of the following embodiments.

[0023] Embodiment 1:

[0024] This embodiment provides a pump body and nozzle connection structure of a spray pump, such as Figure 1-5 As shown, it is used to connect the pump body 1 and the nozzle 2. The connection position of the pump body 1 and the nozzle 2 is detachably connected by a locking member 3. The front end of the pump body 1 is provided with an inner sleeve portion 105, and the tail end of the nozzle 2 is provided with an outer sleeve portion 202 adapted to the inner sleeve portion 105. When the pump body 1 is connected to the nozzle 2, the inner sleeve portion 105 is sleeved in the outer sleeve portion 202, and the outer wall of the outer sleeve portion 202 is provided with an assembly groove 2021. The locking member 3 is movably engaged in the assembly groove 2021, and the locking member 3 can slide in the assembly groove 2021. The locking member 3 is locked in the assembly groove 2021. The fitting 3 has two states through sliding, namely: a locked state in which one end of the locking piece 3 pins the pump body 1, and an unlocked state in which one end of the locking piece 3 is separated from the pump body 1. A sealing ring 1051 is embedded in the outer wall of the inner sleeve part 105. The sealing ring 1051 is elastic and has a semicircular cross-section. The inner wall of the outer sleeve part 202 is provided with a groove adapted to the sealing ring 1051. When the inner sleeve part 105 and the outer sleeve part 202 are sleeved together, the sealing ring 1051 is embedded in the groove, thereby improving the sealing of the connection position after the pump body 1 and the nozzle 2 are connected.

[0025] By adopting the above technical solution:

[0026] The pump body 1 and the nozzle 2 are detachably connected, so when the pump body 1 or the nozzle 2 itself is damaged, it can be disassembled and replaced independently without replacing the entire structure, thereby reducing the maintenance and use costs of the device, and through the mutual fitting effect of the inner layer fitting part 105 and the outer layer fitting part 202, the pump body 1 and the nozzle 2 can be made more stable when connected, and at the same time, through the locking effect of the locking member 3, the stability of the nozzle 2 after installation can be further guaranteed.

[0027] Example 2

[0028] On the basis of Example 1, in this embodiment, a snap-fit ​​groove 2022 is circumferentially provided on the inner wall of the assembly groove 2021 , and a snap-fit ​​portion 301 adapted to the snap-fit ​​groove 2022 is provided at the bottom of the locking member 3 , and the snap-fit ​​portion 301 is slidably snap-fitted into the snap-fit ​​groove 2022 .

[0029] Specifically, the cross-section of the engaging portion 301 is "T"-shaped or "L"-shaped, so that the engaging portion 301 will not abnormally fall out of the engaging groove 2022. Furthermore, an opening is provided at one end of the engaging groove 2022, and the opening can accommodate the engaging portion 301 from falling out. In this way, when the engaging portion 301 or the locking member 3 is damaged, it can be replaced.

[0030] Specifically, the outer walls of the pump body 1 and the nozzle 2 are provided with a connecting female end 101 and a connecting sub-end 201 that match each other at the connecting position. When the pump body 1 is connected to the nozzle 2, the connecting female end 101 and the connecting sub-end 201 are aligned with each other and fixedly connected by bolts.

[0031] By adopting the above technical solution:

[0032] The engaging portion 301 can always remain inside the engaging groove 2022 when sliding, thereby preventing the locking member 3 from abnormally escaping from the assembly groove 2021, causing the pump body 1 and the nozzle 2 to become loose.

[0033] Example 3

[0034] On the basis of Embodiment 1, in this embodiment, a bayonet 1011 is provided on the inner side of the connecting female end 101 along the circumferential direction, and the position of the bayonet 1011 corresponds to the position of the assembly groove 2021 .

[0035] Specifically, a positioning plate 102 is provided on the outer wall of the pump body 1 at one side of the connecting female end 101. When the locking member 3 is in a locked state, a positioning bolt is inserted into the positioning plate 102 and passes through the locking member 3, thereby fixing the locking member 3 and ensuring that the locking member 3 will not loosen and fall off due to the operation vibration of the pump body 1.

[0036] Specifically, a pump body mounting plate 103 is provided on the outer wall of the rear end of the pump body 1, and a rib plate 104 is integrally formed on the main body mounting plate 103, and the rib plate 104 is connected to the connecting female end 101, so that the pump body mounting plate 103, the rib plate 104, and the connecting female end 101 are integrated, thereby improving the overall structural strength and toughness.

[0037] By adopting the above technical solution:

[0038] When one end of the locking component 3 is slid into the inner position of the bayonet 1011, the locking component 3 enters a locked state. When one end of the locking component 3 is slid out to the inner position of the bayonet 1011, the locking component 3 is in an unlocked state. Such a structural setting makes it possible to lock the locking component 3 only through the East China locking component 3, which is convenient and quick to operate.
