Description

Technical Field

[0001] The present invention relates to the field of military equipment, in particular to a novel military portable water bag. Background Art

[0002] Military water bags are water storage devices for marching, generally consisting of an external frame and a flexible surface within the frame. Due to the flexible surface, they can be folded and carried during marches and unfolded when needed. They are highly portable and practical. However, existing military water bags still have the following disadvantages:

[0003] 1. To facilitate use on the march, water bladders are typically larger in volume, making filling them easier. However, due to the large volume and weight of the water inside, draining the water completely is more difficult. Some existing water bladders have a water outlet pipe on their flexible surface, with a valve such as a faucet installed on the pipe to allow the water inside the bladder to flow out. However, typical pipe valves cannot withstand the water pressure inside military water bladders, and simple valves such as faucets are less stable. Prolonged use poses a risk of leakage, and the faucet can also cause water loss due to accidental operation, making them unsuitable for military water bladders.

[0004] 2. The strength of the flexible fabric is insufficient and the support is poor. When the water level in the water bag is high or the water bag is disturbed by external force, the water bag is prone to deformation, causing the internal water to overflow, the water bag to tilt, collapse, etc.

[0005] In view of this, how to provide a new type of military portable water bag that can fully or partially solve the above technical problems is urgently needed to be solved by people in this field. Summary of the Invention

[0006] The purpose of the present invention is to provide a new type of military portable water bag to solve the problems existing in the above-mentioned prior art, so that the military water bag can be easily discharged, the water outlet valve structure is stable, and water leakage and misoperation are avoided.

[0007] To achieve the above-mentioned purpose, the present invention provides the following solutions: The present invention provides a new type of military portable water bag, comprising an upper frame, a water bag body and a lower frame, and also comprising: a water outlet pipe, the water outlet pipe comprising a first pipe and a second pipe made in one piece, the first pipe being connected to the second pipe, the first pipe being communicated with the water bag body, the second pipe being vertically arranged, the second pipe being contracted inward near its bottom end to form a sealed pipe, the bottom of the sealed pipe being a water outlet; a sealing ring, a sealing ring being provided on the inner surface of the sealed pipe; a valve body ball, the valve body ball being arranged in the second pipe, the outer diameter of the valve body ball being larger than the inner diameter of the sealed pipe and smaller than the inner diameter of the second pipe, the valve body ball being able to partially enter the sealed pipe and abut against the sealing ring, the outer surface of the part of the valve body ball that enters the sealed pipe being adapted to the shape of the sealing ring, when the When the valve body ball abuts the sealing ring, the sealing pipe is sealed; a limiting member, the limiting member is located in the second pipe and is spaced apart from the sealing pipe, the limiting member has one or more first water flow channels, and the limiting member can prevent the valve body ball from moving upward along the second pipe; a valve opening member, the valve opening member is a cylindrical structure with upper and lower openings, the upper end of the valve opening member is detachably connected to the sealing pipe, and the lower end of the valve opening member has a mounting seat and a connecting rod, the mounting seat is fixedly connected to the inner surface of the valve opening member through the connecting rod, and a second water flow channel is formed between the connecting rod and the inner surface of the valve opening member; a first push rod, the bottom of the first push rod is fixedly connected to the mounting seat, and the top is a first contact member adapted to the shape of the bottom of the valve body ball. When the valve opening member is connected to the sealing pipe, the first contact member pushes the valve body ball upward away from the sealing pipe.

[0008] The beneficial effects of the present invention are:

[0009] The valve body ball is used as a valve device for draining water from the water bag. The valve body ball is tightly fitted with the upper port and the sealing ring of the sealing pipe under the influence of its own gravity and the downward water pressure. It has extremely strong stability and can effectively prevent water bag leakage. The present application provides a valve opening component that can be separated from the valve body ball. When water needs to be drained, it is only necessary to connect the valve opening component to the sealing pipe, and the first contact component will automatically push the valve body ball open. The water in the water bag can flow downward along the gap between the valve body ball and the second pipe and then flow out from the water outlet, making it convenient for military water bags to discharge water, and can also prevent the problem of water loss caused by misoperation of the valve. It has a simple structure and is easy to use. It has good application prospects and scope of application.

[0010] Furthermore, it also includes a second push rod, the upper end of which is fixedly connected to the limit member, and the lower end has a second contact member that is adapted to the shape of the top of the valve body ball. When the valve opening member is connected to the sealing pipe, the first contact member pushes the valve body ball upward until the valve body ball is fixed between the first contact member and the second contact member.

[0011] Since the outer diameter of the valve body ball is smaller than the inner diameter of the second pipe, when the valve body ball is pushed upward by the first contact piece, the valve body ball will be impacted by the water flow and move irregularly between the limit piece and the first contact piece, which may cause damage to the first contact piece and may also affect the stability of the water outlet. Therefore, the present application sets a second contact piece at the upper end of the valve body ball. When the valve opening piece is connected to the sealing pipe and the first contact piece moves to the uppermost end, it can cooperate with the second contact piece to firmly fix the valve body ball between the first contact piece and the second contact piece, thereby avoiding irregular movement of the valve body ball during the water bag releasing process, providing certain protection for the first contact piece, and providing guarantee for stable water outlet.

[0012] Preferably, the first contact piece and / or the second contact piece are made of rubber.

[0013] In addition to strengthening the friction between the first contact piece and / or the second contact piece made of rubber and the valve body ball, it can also adaptively adjust the fastening force of the first contact piece and the second contact piece on the valve body ball to prevent the first contact piece from excessively upward when the valve opening piece and the sealing pipe are too tight, thereby squeezing the valve body ball. Under this working condition, the first contact piece and / or the second contact piece will undergo adaptive elastic deformation to protect the valve body ball in the middle.

[0014] Preferably, the outer surface of the valve opening member is provided with anti-slip grooves. The anti-slip grooves serve to increase friction between the operator's hand and the valve opening member during installation. To reduce installation difficulty, a threaded connection can be employed between the valve opening member and the sealing pipe, with the sealing pipe having external threads and the corresponding position of the valve opening member having internal threads.

[0015] Furthermore, the limiting member is fixedly connected to the inner side wall of the second pipe, and a plurality of first water flow channels are evenly arranged on the front and rear surfaces of the limiting member, and the inner diameter of the first water flow channel is smaller than the outer diameter of the valve body ball.

[0016] Furthermore, the valve opening member also includes an extension pipe, which is connected to the lower end of the valve opening member. The extension pipe can be communicated with an external pipe, and an electric-controlled pump is provided on the external pipe.

[0017] When the water discharge position is far away from the water bag, it is obviously unreasonable to move the water bag to the water discharge position. Therefore, this application adds an extension pipe at the end of the valve opening member. The extension pipe can be set to a standard model and can be connected to most external pipes, so that the water in the water bag flows from the water outlet into the external pipe and finally flows to the water discharge position.

[0018] Furthermore, it also includes a heating metal sheet. The bottom of the water bag body is open, and the heating metal sheet is arranged at the bottom opening and fixedly connected to the inner edge of the bottom opening.

[0019] During use, the water bag does not actually have the function of heating water. Therefore, the water bag body at the bottom of the water bag can be replaced with a heating metal sheet that can be heated, and the water bag can be placed directly above the fire for heating.

[0020] Furthermore, it also includes: an articulated seat, the lower frame is composed of a plurality of lower connecting rods connected end to end in sequence, the water bag body is fixedly connected to the inner side surface of the lower connecting rod, and the articulated seat is arranged near the right end of each of the lower connecting rods; a hinged rod, one end of the hinged rod is fixedly connected to the side surface of the articulated seat, and the other end extends horizontally toward the direction of the water bag body; a first limit block, one side of the first limit block is fixedly connected to the outer side surface of the water bag body, and the other side is fixedly connected to the other end of the articulated rod; a support rod, the support rod is hinged to the articulated rod and is located between the first limit block and the articulated seat, and when the support rod is rotated to a vertical direction, the support rod can support the upper frame.

[0021] The beneficial effects of adopting the above technical solution are:

[0022] Before use, rotate the support rod along the hinged rod to the vertical direction. At this time, the support rod uses the lower bracket as the fulcrum to generate supporting force on the upper bracket, preventing the upper bracket from moving downward and causing the water bag to deform when the amount of water in the water bag is too large. This greatly improves the stability of the water bag and can effectively prevent the water in the water bag from overflowing.

[0023] Furthermore, it also includes: a fixing block, the upper frame is composed of a plurality of upper connecting rods connected end to end in sequence, the water bag body is fixedly connected to the inner side of the upper connecting rod, and the fixing block is arranged near the left end of each of the upper connecting rods; a first screw hole is provided on the fixing block, and a second screw hole is provided on the support rod; when the support rod is rotated to a vertical direction, the support rod abuts against the fixing block and the positions of the first screw hole and the second screw hole correspond to each other; a fastening screw, the fastening screw can be inserted into the first screw hole from the second screw hole and threadedly connected to the first screw hole and the second screw hole respectively.

[0024] When the support rod is moved to the vertical direction, although it can support the upper bracket, it is still very easy to rotate left and right if the support rod is subjected to a horizontal external force. Therefore, the present application provides a fixing block on the upper frame. The support rod supports the upper frame while also being fixed by the fixing block. In addition, the upper connecting rod actually supported by the support rod and the upper connecting rod connected to the fixing block are not the same connecting rod, but two adjacent connecting rods. Therefore, when the support rod is subjected to a horizontal external force, the support rod is not only fixed by the fixing block, but also affected by the interaction force between the two adjacent connecting rods, further improving stability. Therefore, the support rod is difficult to rotate due to the influence of the horizontal external force, that is, the stability of the water bag is further enhanced.

[0025] Furthermore, it also includes: a second limit block, which is adjacent to the right side of the bottom end of the support rod. When the support rod is rotated to a vertical direction, the right side of the support rod abuts against the second limit block, and the second limit block can prevent the support rod from continuing to rotate to the right.

[0026] The second limit block has two functions. The first is positioning. When the support rod rotates to the position abutting the limit block, it can be directly considered that the support rod has rotated to the vertical direction, and the top of the support rod can be abutted against the upper frame. The second is limiting. After the support rod supports the upper frame, it cannot continue to rotate to the right due to the influence of the second limit block. Used in conjunction with the fixed block, it can further improve the stability of the water bag and prevent the water bag from deformation, tilting, and collapse. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Reference Figure 1-15 The present invention provides a new type of military portable water bag, including an upper frame 1, a water bag body 2 and a lower frame 3, and also includes: a water outlet pipe 4, the water outlet pipe 4 includes a first pipe 401 and a second pipe 402 made in one piece, the first pipe 401 is connected to the second pipe 402, the first pipe 401 is connected to the water bag body 2, the second pipe 402 is vertically arranged, the second pipe 402 is contracted inwardly near its bottom end to form a sealed pipe 4021, and the bottom of the sealed pipe 4021 is a water outlet; a sealing ring 5, a sealing ring 5 is provided on the inner surface of the sealing pipe 4021; a valve body ball 6, the valve body ball 6 is arranged in the second pipe 402, the outer diameter of the valve body ball 6 is larger than the inner diameter of the sealing pipe 4021 and smaller than the inner diameter of the second pipe 402, the valve body ball 6 can partially enter the sealing pipe 4021 and abut against the sealing ring 5, the outer surface of the part of the valve body ball 6 that enters the sealing pipe 4021 is adapted to the shape of the sealing ring 5, when the valve body ball 6 and the sealing ring When the sealing ring 5 abuts, the sealing pipe 4021 is sealed; the limiting member 7, the limiting member 7 is located in the second pipe 402 and is spaced apart from the sealing pipe 4021, the limiting member 7 has one or more first water flow channels, and the limiting member 7 can prevent the valve body ball 6 from moving upward along the second pipe 402; the valve opening member 8, the valve opening member 8 is a cylindrical structure with upper and lower openings, the upper end of the valve opening member 8 is threadedly connected to the sealing pipe 4021, and the lower end of the valve opening member 8 has a mounting seat 801 and a connecting rod 802, the mounting seat 801 is fixedly connected to the inner surface of the valve opening member 8 through the connecting rod 802, and a second water flow channel is formed between the connecting rod 802 and the inner surface of the valve opening member 8; the first push rod 9, the bottom of the first push rod 9 is fixedly connected to the mounting seat 801, and the top is a first contact member 901 that is adapted to the shape of the bottom of the valve body ball 6. When the valve opening member 8 is connected to the sealing pipe 4021, the first contact member 901 pushes the valve body ball 6 upward away from the sealing pipe 4021.

[0050] The sizes of the valve body ball 6, the second pipe 402, and the sealing pipe 4021 are closely related. When the valve body ball 6 moves upward away from the sealing pipe 4021, the water in the water bag body 2 needs to flow downward from the gap between the valve body ball 6 and the sealing pipe 4021. If the gap is too small, the water flow rate is small and the water discharge speed is slow. If the gap is too large, the production cost of the second pipe 402 is increased, and the valve body ball 6 is not easy to reset after the water discharge is completed (restoring the state of abutment and sealing with the sealing pipe 4021). Therefore, in actual application, it is necessary to design the sizes of the valve body ball 6, the second pipe 402, and the sealing pipe 4021 according to the overall volume of the water bag body 2 and the required water discharge speed to ensure sufficient water discharge speed, appropriate production cost, and easy reset of the valve body ball 6. In some embodiments, a structure such as an inclined surface can also be provided near the second pipe 402 and the sealing pipe 4021 to help the valve body ball 6 quickly reset.

[0051] In some embodiments, the limiter 7 is fixedly connected to the inner wall of the second pipe 402 , and a plurality of first water flow channels are evenly arranged on the front and rear surfaces of the limiter 7 , and the inner diameter of the first water flow channel is smaller than the outer diameter of the valve body ball 6 .

[0052] In this embodiment, a second push rod 10 is also included, the upper end of the second push rod 10 is fixedly connected to the limit member 7, and the lower end has a second contact member 1001 that is adapted to the top shape of the valve body ball 6. When the valve opening member 8 is connected to the sealing pipe 4021, the first contact member 901 pushes the valve body ball 6 upward until the valve body ball 6 is fixed between the first contact member 901 and the second contact member 1001.

[0053] After the second push rod 10 is installed, the function of the stopper 7 is no longer necessary. The second push rod 10 itself can limit the valve body ball 6 and prevent the valve body ball 6 from moving upward along the second pipe 402. Therefore, in this embodiment, the stopper 7 is directly made into a structure with multiple hollows, retaining only the mounting portion of the second push rod 10 and the connection structure between the mounting portion and the inner wall of the second pipe 402 (in fact, this structure is exactly the same as the mounting seat 801 and connecting rod 802 at the bottom end of the valve opening member 8). This increases the water flow at the stopper 7 and improves the water discharge speed. The first contact member 901 and the second contact member 1001 are both made of rubber, and the outer surface of the valve opening member 8 is provided with anti-slip grooves 803.

[0054] In this embodiment, the valve opening member 8 further includes an extension pipe 11 , which is connected to the lower end of the valve opening member 8 . The extension pipe 11 can be communicated with an external pipe, and an electric-controlled pump is provided on the external pipe.

[0055] In this embodiment, a heating metal sheet is also included. The water bladder body 2 has an opening at the bottom, and the heating metal sheet is disposed within the bottom opening and fixedly connected to the inner edge of the bottom opening. Furthermore, to enhance ease of use, a removable support frame can be installed beneath the lower frame 3. The support frame can elevate the water bladder body 2, facilitating the construction of a fire pit, etc., beneath the heating metal sheet. The water bladder body 2 should be made of a flexible material that is waterproof, heat-insulating, high in strength, and high in toughness. This material can be a composite flexible material, such as an inner waterproof rubber layer and an outer wear-resistant and fire-resistant canvas layer. In other embodiments, a heating circuit can be provided within the heating metal sheet to heat the water within the water bladder body 2 using solar energy, an external power source, or the like, to ensure normal use in winter or during low temperatures.

[0056] In this embodiment, it also includes: an articulated seat 12, the lower frame 3 is composed of a plurality of lower connecting rods 301 connected end to end, the water bag body 2 is fixedly connected to the inner side of the lower connecting rod 301, and the articulated seat 12 is arranged near the right end of each lower connecting rod 301; an articulated rod 13, one end of the articulated rod 13 is fixedly connected to the side of the articulated seat 12, and the other end extends horizontally toward the direction of the water bag body 2; a first limit block 14, one side of the first limit block 14 is fixedly connected to the outer side of the water bag body 2, and the other side is fixedly connected to the other end of the articulated rod 13; a support rod 15, the support rod 15 is hinged to the articulated rod 13 and is located between the first limit block 14 and the articulated seat 12. When the support rod 15 is rotated to a vertical direction, the support rod 15 can support the upper frame 1. Since the lower end of the support rod 15 is in direct contact with the lower frame 3, the lower end of the support rod 15 is set as an arc surface to avoid being unable to rotate. When the support rod 15 is rotated to the vertical position, the middle position of the arc surface abuts against the lower frame 3.

[0057] In this embodiment, it also includes: a fixing block 16, the upper frame 1 is composed of a plurality of upper connecting rods 101 connected end to end in sequence, the water bag body 2 is fixedly connected to the inner side of the upper connecting rod 101, and the fixing block 16 is arranged near the left end of each upper connecting rod 101; a first screw hole 1601 is provided on the fixing block 16, and a second screw hole 1501 is provided on the support rod 15; when the support rod 15 is rotated to a vertical direction, the support rod 15 abuts against the fixing block 16 and the positions of the first screw hole 1601 and the second screw hole 1501 correspond to each other; a fastening screw, the fastening screw can be inserted into the first screw hole 1601 from the second screw hole 1501 and threadedly connected to the first screw hole 1601 and the second screw hole 1501 respectively.

[0058] In this embodiment, a second stopper 17 is further included. The second stopper 17 is located adjacent to the right side of the bottom end of the support rod 15. When the support rod 15 rotates to a vertical position, the right side of the support rod 15 abuts the second stopper 17, thereby preventing the support rod 15 from further rotating to the right. To ensure that the installation position of the second stopper 17 does not affect the return of the support rod 15 to the adjacent lower connecting rod 301, the length of the lower connecting rod 301 can be set to be greater than the length of the support rod 15, leaving sufficient space for the installation of the second stopper 17. In this case, the width of the water bladder body 2 is greater than its height after expansion, which can also improve the overall stability of the water bladder body 2 to a certain extent.

[0059] like Figure 17-18 As shown, in some other embodiments, a top surface 18 may be provided above the water bladder body 2. The function of the top surface 18 is to prevent fallen leaves, dust, etc. from falling into the water bladder body 2 when the water bladder body 2 is used outdoors and causing contamination. In this case, the top opening of the water bladder body 2 is sealed, so a water inlet is provided on the top surface 18. A one-way valve 19 is provided at the water inlet. The one-way valve 19 can be connected to equipment such as a military water truck or a water supply pipeline, and water enters the water bladder body 2 through the one-way valve 19. In order to remove impurities in the water used in the field, a corresponding filter layer 20, such as gauze, can be provided at the one-way valve 19. A filter element such as a pre-filter can also be provided to filter the water without affecting the water flow rate.

[0060] The specific working process is as follows:

[0061] 1. Valve opening process of valve opening member 8

[0062] In the initial state, a large amount of water is stored in the water bag body 2. The valve ball 6 is tightly fitted with the upper end of the sealing pipe 4021 and the sealing ring 5 under the influence of its own gravity and water pressure, so that the sealing pipe 4021 is sealed and the water in the water bag body 2 cannot flow out from the water outlet. When it is necessary to open the valve to release water, the operator holds the valve opening member 8, extends the first contact member 901 into the sealing pipe 4021, and applies force in the direction of the second pipe 402 while twisting the valve opening member 8 so that the valve opening member 8 is threadedly connected and fixed to the sealing pipe 4021. During the process, the valve body ball 6 is moved toward the second contact member 1001 by the thrust of the first contact member 901 (the first push rod 9 is located on the central axis of the valve opening member 8, and the position of the first contact member 901 remains unchanged during the twisting of the valve opening member 8). When the valve opening member 8 is completely fixed to the sealing pipe 4021, the valve body ball 6 is squeezed and fixed by the first contact member 901 and the second contact member 1001. At this time, the water in the water bag body 2 flows through the first pipe 401, the second pipe 402, and the sealing pipe 4021 in turn to the water outlet and finally flows out from the tail end of the valve opening member 8; when it is necessary to change the water release position, it is only necessary to connect the external pipe with the extension pipe 11 before opening the valve to release water.

[0063] 2. The process of supporting the water bag body 2 by the support rod 15

[0064] In the initial state, the support rod 15 is placed horizontally on the lower connecting rod 301. The operator holds the upper connecting rod 101 and pulls the water bag body 2 upward to make the upper connecting rod 101 reach the position where the water bag body 2 is fully expanded, and rotates the support rod 15 to the right. During the rotation process, the arc surface at the bottom end of the support rod 15 always abuts against the lower support rod 15. When rotated to the vertical position, the support rod 15 abuts against the second limit block 17 on its right side, and the top end abuts against the lower surface of the upper connecting rod 101 (the height of the upper frame 1 is slightly higher than the length of the support rod 15 to facilitate the rotation of the support rod 15 to the upper connecting rod 101 When the support rod 15 is rotated to the vertical position, the water bag body 2 can be gently pulled downward to make the upper connecting rod 101 contact the support rod; when in use, water is filled in the water bag body 2, and the tension of the water will cause the water bag body 2 to expand. At this time, the upper connecting rod 101 will move down a distance and fit tightly with the support rod 15), align the upper end of the support rod 15 with the fixing block 16, so that the first screw hole 1601 and the second screw hole 1501 correspond to each other, and connect the fastening screws with the second screw hole 1501 and the second screw hole 1501 respectively to complete the fixation of the support rod 15 and the fixing block 16, and then it can be used normally.

[0065] The present invention adopts a valve body ball as a valve device for draining water from the water bag. The valve body ball is tightly fitted with the upper port and the sealing ring of the sealing pipe under the influence of its own gravity and downward water pressure, and has extremely strong stability, which can effectively prevent water leakage from the water bag. When water needs to be drained, it is only necessary to connect the valve opening member to the sealing pipe, and the first contact member automatically pushes the valve body ball open, and the water in the water bag can flow downward along the gap between the valve body ball and the second pipe and then flow out from the water outlet, making it convenient for military water bags to discharge water, and can also prevent the problem of water loss caused by improper operation of the valve, with a simple structure and easy use. In addition, the lower bracket of the outer support rod of the water bag body is used as a fulcrum to generate a supporting force on the upper bracket, so as to avoid the upper bracket moving downward when the amount of water in the water bag is too large, causing the water bag to deform, thereby greatly improving the stability of the water bag and effectively preventing the water in the water bag from overflowing.
