DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here, for example.

[0037] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0038] When the inner tank of a water heater of the related technology needs to be inflated, each water heater needs to be placed on a work trolley, and multiple work trolleys are placed on an elliptical track so that the multiple work trolleys can be driven on the elliptical track. When the work trolley drives the water heater to move to the position of the inflation device, the inflation of the inner tank is achieved by connecting the inflation pipeline of the inflation device with the air inlet pipeline of the water heater inner tank. Usually, a female plug is provided on the inflation pipeline of the inflation device, and a female plug is provided on the air inlet pipeline of the water heater inner tank. The female plug and the male plug are plugged together to achieve fixation and connection between the inflation pipeline and the air inlet pipeline, thereby facilitating inflation of the inner tank.

[0039] However, the male plug is usually fixed to the air inlet pipe manually. When the inflation pipe of the inflation device is connected or disconnected with the air inlet pipe of the water heater inner tank, the female plug and the male plug on the inflation pipe and the air inlet pipe need to be manually plugged in and out, which wastes manpower.

[0040] In order to solve the above technical problems, the present application provides an automatic gas connection device. When the tooling trolley drives the inner tank of the water heater to move to the position of the inflation device through the elliptical track, the driving mechanism drives the movable seat to move toward the fixed seat, so that the male plug is plugged into the inner cylinder. The male plug can drive the opening and closing cylinder to move toward the movable seat, so that the opening and closing hole is driven to move into the connecting space. The driving part drives the outer cylinder to move in the direction away from the movable seat, so that the outer cylinder drives the second closed end to guide the ball into the groove, so that the male plug is locked into the female plug. At this time, the gas can flow along the first connecting hole, the inner cylinder, and the connecting hole. The space, the opening and closing hole, the opening and closing cylinder and the male plug enter into the second connecting hole, so that the gas is filled into the inner tank; when the inflation is completed, the outer tank is driven to move toward the moving seat by the driving part, and at this time the driving mechanism drives the female plug away from the male plug. Due to the setting of the first elastic member, the opening and closing cylinder moves in the direction away from the moving seat. At this time, the groove can drive the ball part to move into the groove body, and the opening and closing cylinder can move out of the connecting space, so that the inner wall of the inner tank closes the opening and closing hole, and the gas cannot be discharged from the inner tank at this time; by repeating the above steps, the automatic inflation of multiple inner tanks can be realized, which saves the manpower of manually plugging and unplugging the female plug and the male plug.

[0042] In this embodiment, the male plug 200 is used to be plugged into the female plug 100 to achieve connectivity between the male plug 200 and the female plug 100; a plurality of male plugs 200 are provided, and the plurality of male plugs 200 can be installed on the inner tanks of a plurality of water heaters by manual pre-installation, or the male plugs 200 can be automatically installed on the inner tanks of a plurality of water heaters by a robot, so that the use of the robot saves some manpower.

[0043] By adopting the above technical solution, when it is necessary to inflate the inner tanks of multiple water heaters, multiple mobile tooling can be moved to the position of the inflation device in sequence, and the driving mechanism 300 can drive the female plug 100 to move toward the male plug 200, so that the female plug 100 and the male plug 200 are plugged into each other. At this time, the gas in the inflation pipeline can be sent into the inner tank along the female plug 100 and the male plug 200 to achieve inflation of the inner tank, without the need for manual plugging and unplugging of the female plug 100 and the male plug 200, thereby saving manpower; by adopting the locking mechanism The setting of 400 can fix the female plug 100 and the male plug 200 to each other when the female plug 100 and the male plug 200 are plugged in, thereby preventing the female plug 100 and the male plug 200 from being separated due to the impact of gas, improving the stability of gas being transported from the female plug 100 and the male plug 200 to the inner tank, and by fixing the female plug 100 and the male plug 200, the sealing effect between the female plug 100 and the male plug 200 is indirectly improved, preventing the gas from flowing out along the gap between the female plug 100 and the male plug 200.

[0046] By adopting the above technical solution, by always keeping the inflation pipeline of the inflation device connected to the first connecting hole 510, when inflation is needed, the inflation device can be driven to open so that the gas can enter the first connecting hole 510 along the inflation device, and then enter the female plug 100 along the first connecting hole 510, without constantly plugging and unplugging the inflation pipeline and the female plug 100, thereby further saving manpower and improving the stability of transporting gas from the inflation device to the female plug 100; by detachably connecting the female plug 100 to the movable seat 500, the female plug 100 is easy to repair and replace.

[0047] Combination Figures 1 to 3 The automatic air connection device also includes a fixing base 700, and the male plug 200 is detachably connected to the fixing base 700. A second connecting hole 710 is provided on the fixing base 700. One end of the second connecting hole 710 is used to communicate with the air intake pipeline, and the other end is connected with the male plug 200.

[0048] In this embodiment, the cross-section of the male plug 200 is arranged in an annular shape, and one end of the annular male plug 200 is inserted and threadedly connected to the fixing base 700. The male plug 200 is detachably connected to the fixing base 700 by means of a threaded connection. The fixing base 700 is arranged as a rectangular block as a whole.

[0049] By adopting the above technical solution, by always keeping the air inlet pipe of the inner tank connected with the second connecting hole 710, when the female plug 100 and the male plug 200 are plugged in, the gas can enter the second connecting hole 710 along the male plug 200, and enter the air inlet pipe along the second connecting hole 710, without the need to constantly plug and unplug the male plug 200 and the air inlet pipe, thereby further saving manpower and improving the stability of transporting the gas from the male plug 200 to the air inlet pipe; by detachably connecting the male plug 200 to the fixing seat 700, the male plug 200 is easy to repair and replace.

[0050] Combination Figures 1 to 3 The female plug 100 includes an inner cylinder 110 and an opening and closing member 120. A connecting space 130 is provided in the inner cylinder 110. The connecting space 130 is connected to the first connecting hole 510. The opening and closing member 120 is slidably provided in the inner cylinder 110. The opening and closing member 120 is configured to move into or out of the connecting space 130 when the male plug 200 is plugged in or out of the female plug 100, so as to connect or disconnect the male plug 200 and the female plug 100.

[0051] By adopting the above technical solution, when the male plug 200 is plugged into the female plug 100, the opening and closing member 120 can be moved into the connecting space 130, so that the opening and closing member 120 connects the male plug 200 and the female plug 100 through the connecting space 130; when the male plug 200 is detached from the female plug 100, the opening and closing member 120 can be moved out of the connecting space 130, so that the opening and closing member 120 disconnects the connection between the male plug 200 and the female plug 100; the arrangement of the inner cylinder 110 and the opening and closing member 120 has a simple structure; the connection and disconnection of the male plug 200 and the female plug 100 can be realized by driving the male plug 200 and the female plug 100 to be plugged in or detached from the plugging, thereby improving the degree of automation of the connection and disconnection of the male plug 200 and the female plug 100.

[0052] Combination Figures 1 to 3 The opening and closing member 120 includes an opening and closing cylinder 121 and a first elastic member 122. A plurality of opening and closing holes 123 are arranged on the opening and closing cylinder 121 along the circumference of the opening and closing cylinder 121. The end of the opening and closing cylinder 121 close to the movable seat 500 is arranged as a first closed end 124, and the end of the opening and closing cylinder 121 away from the movable seat 500 is arranged as a first open end 125. The first elastic member 122 is used to drive the opening and closing cylinder 121 to move out of the connecting space 130 when the male plug 200 and the female plug 100 are disengaged. The opening and closing cylinder 121 is configured to move into the connecting space 130 when the male plug 200 and the female plug 100 are connected.

[0053] In this embodiment, the cross-section of the opening and closing cylinder 121 is annular, and the first closed end 124 is conical as a whole. By adopting the conical first closed end 124, the gas entering the inner cylinder 110 can be guided to the surroundings through the conical first closed end 124, thereby guiding the gas into the connecting space 130 and entering the opening and closing cylinder 121 through the opening and closing hole 123 along the connecting space 130; the first elastic member 122 is configured as a spring, the spring is coaxially arranged with the opening and closing cylinder 121, and one end of the spring is connected to the surface of the connecting space 130 away from the opening and closing cylinder 121, and the other end is connected to the outer wall of the first closed end 124.

[0054] By adopting the above technical solution, when the male plug 200 is plugged into the female plug 100, the opening and closing cylinder 121 can be moved into the connecting space 130, so that the gas in the first connecting hole 510 can enter the opening and closing cylinder 121 along the inner cylinder 110, the connecting space 130 and the opening and closing hole 123, and the gas entering the opening and closing cylinder 121 can enter the second connecting hole 710 through the first opening end 125 and the male plug 200, thereby realizing the inflation of the inner liner; when the male plug 200 and the female plug 100 are disconnected, at this time, due to the design of the first elastic member 122 The device is capable of driving the opening and closing cylinder 121 to move out of the connecting space 130, so that the opening and closing hole 123 cannot be connected with the connecting space 130. Because the end of the opening and closing cylinder 121 close to the movable seat 500 is set as the first closed end 124, the gas cannot enter the opening and closing cylinder 121 along the inner cylinder 110 and the connecting space 130, thereby realizing the closure of the female plug 100 and preventing the gas from continuously spraying out from the female plug 100, thereby affecting the plug-in fit between the male plug 200 and the female plug 100, and further improving the plug-in fit stability between the male plug 200 and the female plug 100.

[0055] In this embodiment, a first sealing ring 111 is embedded on the inner wall of the inner cylinder 110 along the circumference of the inner cylinder 110. The first sealing ring 111 is located on the side of the connecting space 130 away from the movable seat 500. When the opening and closing cylinder 121 moves out of the connecting space 130, the first sealing ring 111 can abut against the outer side wall of the opening and closing cylinder 121 close to the connecting space 130, thereby preventing the gas from being ejected along the gap between the inner cylinder 110 and the opening and closing cylinder 121 when the opening and closing cylinder 121 moves out of the connecting space 130; a second sealing ring 126 is embedded on the inner wall of the opening and closing cylinder 121 along the circumference of the opening and closing cylinder 121. When the male plug 200 is inserted into the opening and closing cylinder 121, the second sealing ring 126 can abut against the outer wall of the male plug 200, thereby preventing the gas from being ejected along the gap between the opening and closing cylinder 121 and the male plug 200.

[0056] Combination Figures 1 to 3The communicating space 130 is arranged in the middle of the inner cylinder 110 , and the inner diameter of the communicating space 130 is larger than the outer diameter of the opening and closing cylinder 121 , and the outer wall of the opening and closing cylinder 121 is used to abut against the inner wall of the inner cylinder 110 .

[0057] In this embodiment, the inner cylinder 110 is divided into three parts. The part of the inner cylinder 110 close to the movable seat 500 is the first part for threaded connection with the movable seat 500, the middle part of the inner cylinder 110 is the second part where the connecting space 130 is located, and the part of the inner cylinder 110 away from the movable seat 500 is the third part for plugging with the male plug 200. The inner walls of the first part and the third part of the inner cylinder 110 are used to abut against the outer wall of the opening and closing cylinder 121; when the opening and closing cylinder 121 moves into the connecting space 130, the opening and closing cylinder 121 can drive the opening and closing hole 123 to be located in the connecting space 130. At this time, the part of the opening and closing cylinder 121 away from the movable seat 500 is in the third part, so that the outer wall of the opening and closing cylinder 121 abuts against the first sealing ring 111, thereby preventing the gas from spraying out along the gap between the inner cylinder 110 and the opening and closing cylinder 121.

[0058] By adopting the above technical solution, by making the inner diameter of the connecting space 130 larger than the outer diameter of the opening and closing cylinder 121, when the opening and closing cylinder 121 is moved into the connecting space 130, the inner wall of the connecting space 130 will not close the opening and closing hole 123, so that the gas entering the inner cylinder 110 through the first connecting hole 510 can enter the opening and closing cylinder 121 along the connecting space 130 and the opening and closing hole 123, and then enter the male plug 200 along the opening and closing cylinder 121 and the open end. By making the inner diameter of the connecting space 130 larger than the outer diameter of the opening and closing cylinder 121, when the opening and closing cylinder 121 enters the connecting space 130, Automatic communication between the inner cylinder 110 and the opening and closing cylinder 121 is achieved; by abutting the outer wall of the opening and closing cylinder 121 with the inner wall of the inner cylinder 110, when the opening and closing cylinder 121 moves out of the connecting space 130, the opening and closing cylinder 121 can abut against the inner wall of the inner cylinder 110, so that the opening and closing hole 123 is closed by the inner wall of the inner cylinder 110, preventing the gas in the inner cylinder 110 from entering the opening and closing cylinder 121 through the opening and closing hole 123, so that the opening and closing cylinder 121 moves out of the connecting space 130, and the automatic sealing of the inner cylinder 110 and the opening and closing cylinder 121 can be achieved, thereby improving the connection and sealing effect between the inner cylinder 110 and the opening and closing cylinder 121.

[0059] Combination Figures 1 to 3 A convex edge 210 is provided on the male plug 200 along the circumference of the male plug 200 , and the convex edge 210 is used to abut against the first opening end 125 to drive the opening and closing cylinder 121 to move toward the connecting space 130 .

[0060] In this embodiment, the cross-section of the convex edge 210 is set to be an isosceles trapezoid, and the first open end 125 is used to cooperate with one of the waists of the isosceles trapezoid, so that the convex edge 210 can drive the opening and closing cylinder 121 to move toward the movable seat 500 through the first open end 125; in other embodiments, the convex edge 210 can also be replaced by a plurality of protrusions evenly distributed along the circumference of the male plug 200.

[0061] By adopting the above-mentioned technical solution, when the male plug 200 is plugged into the female plug 100, the male plug 200 can drive the convex edge 210 to abut against the first opening end 125, so that the convex edge 210 drives the opening and closing cylinder 121 to move, thereby driving the opening and closing cylinder 121 to move into the connecting space 130. The driving of the opening and closing cylinder 121 can be realized without the need for other additional driving parts 432, thereby improving the effect of the opening and closing cylinder 121 moving into the connecting space 130.

[0062] Combination Figures 1 to 3 The locking mechanism 400 includes a groove 410, a plurality of balls 420 and a driving member 430. The groove 410 is arranged along the circumference of the male plug 200. The balls 420 are radially penetrated along the opening and closing cylinder 121 and are slidably connected to the opening and closing cylinder 121. The driving member 430 is configured to drive the balls 420 to move into or out of the groove 410 when the opening and closing cylinder 121 moves into the connecting space 130, so as to fix or detach the male plug 200 and the female plug 100.

[0063] In this embodiment, the cross-section of the groove 410 is also set to be an isosceles trapezoid, and one of the waists of the isosceles trapezoidal groove 410 is shared with one of the waists of the isosceles trapezoidal convex edge 210. By setting the cross-section of the groove 410 to be an isosceles trapezoid, when the opening and closing cylinder 121 moves, the inclined waist of the isosceles trapezoidal groove 410 can drive the ball 420 to move outside the groove 410, thereby achieving a guiding effect on the ball 420; multiple balls 420 are located at a position of the inner cylinder 110 away from the movable seat 500.

[0064] By adopting the above technical solution, when the opening and closing cylinder 121 moves into the connecting space 130, the driving member 430 can drive the ball 420 to move into the groove 410, so that the ball 420 and the groove 410 prevent the inner cylinder 110 and the male plug 200 from disengaging, thereby locking the inner cylinder 110 and the male plug 200 to a fixed state to prevent the inner cylinder 110 and the male plug 200 from disengaging due to the impact of gas; when the opening and closing cylinder 121 moves out of the connecting space 130, the driving member 430 can drive the ball 420 to move out of the groove 410, so that the inner cylinder 110 and the male plug 200 can be separated from each other; by adopting the arrangement of the groove 410, the ball 420 and the driving member 430, the male plug 200 is locked in the circumferential direction, thereby improving the fixing strength between the inner cylinder 110 and the male plug 200.

[0065] Combination Figures 1 to 3 The driving member 430 includes an outer cylinder 431 and a driving portion 432. A groove body 433 is arranged on the outer cylinder 431 along the circumference of the outer cylinder 431. The groove body 433 is used for partially moving the ball 420 into. The side of the groove body 433 away from the moving seat 500 is set as a second open end 435, and the side of the groove body 433 close to the moving seat 500 is set as a second closed end 434. The outer cylinder 431 is sleeved and slidably connected to the inner cylinder 110. The driving portion 432 is used to drive the outer cylinder 431 away from or close to the moving seat 500, so that the second closed end 434 abuts against or disengages from the ball 420.

[0066] In this embodiment, the cross-section of the outer cylinder 431 is annular, and the bottom wall of the second closed end 434 is inclined. By setting the bottom wall of the second closed end 434 to be inclined, when the outer cylinder 431 moves in a direction away from the movable seat 500, the outer cylinder 431 can drive the inclined bottom wall of the second closed end 434 to guide the ball 420, so as to guide the ball 420 into the groove 410; the driving part 432 includes a second cylinder 436 and a sleeve 437, the second cylinder 436 is fixedly arranged on the movable seat 500, the sleeve 437 is fixedly arranged on the driving end of the second cylinder 436, and the sleeve 437 is sleeved and fixedly connected to the outer cylinder 431, so that the second cylinder 436 can drive the sleeve 437 to drive the outer cylinder 431 to move on the inner cylinder 110.

[0067] By adopting the above technical solution, when the male plug 200 is plugged into the female plug 100, the outer cylinder 431 is driven away from the movable seat 500 by the driving part 432. At this time, since the side of the groove body 433 close to the movable seat 500 is the second closed end 434, the second closed end 434 can abut against the ball 420, so that the second closed end 434 pushes the ball 420 into the groove 410. At this time, the inner wall of the outer cylinder 431 abuts against the ball 420; When the plug 200 is disconnected from the female plug 100, the driving part 432 drives the outer cylinder 431 to approach the movable seat 500. At this time, the second closed end 434 of the groove body 433 is away from the ball 420. When the male plug 200 is disconnected from the female plug 100, the groove 410 can drive the ball 420 to partially move into the groove body 433. At this time, the ball 420 can move out of the groove 410, thereby releasing the lock between the inner cylinder 110 and the male plug 200.

[0068] Combination Figures 1 to 3 A second elastic member 112 is sleeved on the outer wall of the inner cylinder 110 , one end of the second elastic member 112 is connected to the inner cylinder 110 , and the other end is connected to the outer cylinder 431 .

[0069] In this embodiment, the second elastic member 112 is configured as a spring, which is sleeved on the outer wall of the inner cylinder 110 , and one end of the spring is fixedly connected to the inner cylinder 110 , and the other end of the spring is fixedly connected to the outer cylinder 431 .

[0070] By adopting the above technical solution, the second elastic member 112 is provided to facilitate the resetting between the inner cylinder 110 and the outer cylinder 431 and prevent the inner cylinder 110 and the outer cylinder 431 from deviating along their axial direction when moving, thereby improving the moving effect of the inner cylinder 110 and the outer cylinder 431.

[0071] In this embodiment, a third sealing ring 113 is embedded along the circumference of the inner cylinder 110 on the outer wall of the inner cylinder 110 and at a position away from the movable seat 500. When the driving part 432 drives the outer cylinder 431 to move in a direction away from the movable seat 500, the third sealing ring 113 can abut against the inner wall of the outer cylinder 431, thereby preventing the gas from spraying out along the gap between the outer cylinder 431 and the inner cylinder 110.

[0072] When the tooling trolley drives the inner tank of the water heater to move to the position of the inflation device through the elliptical track, the driving mechanism 300 drives the movable seat 500 to move toward the fixed seat 700, so that the male plug 200 is plugged into the inner cylinder 110, and the male plug 200 can drive the opening and closing cylinder 121 to move toward the movable seat 500, so as to drive the opening and closing hole 123 to move into the connecting space 130, and the driving part 432 drives the outer cylinder 431 to move in the direction away from the movable seat 500, so that the outer cylinder 431 drives the second closed end 434 to guide the ball 420 into the groove 410, so that the male plug 200 is locked into the female plug 100, and the gas can flow along the first connecting hole 510, the inner cylinder 110, the connecting space 130, the opening and closing hole 123, the opening and closing cylinder 1 21 and the male plug 200 enter into the second connecting hole 710, so that the gas is filled into the inner liner; when the inflation is completed, the outer cylinder 431 is driven to move toward the moving seat 500 by the driving part 432, and at this time the driving mechanism 300 drives the female plug 100 away from the male plug 200. Due to the setting of the first elastic member 122, the opening and closing cylinder 121 moves in the direction away from the moving seat 500. At this time, the groove 410 can drive the ball 420 to partially move into the groove body 433, and the opening and closing cylinder 121 can move out of the connecting space 130, so that the inner wall of the inner cylinder 110 closes the opening and closing hole 123, and the gas cannot be discharged from the inner cylinder 110 at this time; by repeating the above steps, the automatic inflation of multiple inner liner can be realized, which saves the manpower of manually plugging and unplugging the female plug 100 and the male plug 200.
