Description

Technical Field

[0001] This utility model relates to the field of bracket positioning technology, and in particular to a positioning fixture for the inner tank bracket of a water heater. Background Technology

[0002] In the modern water heater manufacturing industry, with the continuous improvement of energy efficiency and environmental protection requirements, heat pump electric water heaters have gradually become one of the mainstream products in the market due to their high efficiency, energy saving and low carbon emissions. Heat pump electric water heaters use a compressor to drive the refrigerant circulation, transferring heat energy from the air to the inner tank to heat the water. The structure of its inner tank is more complex than that of traditional electric water heaters, and the installation accuracy and stability requirements of the inner tank support are higher. The inner tank support not only needs to bear the weight of the inner tank and hot water, but also needs to ensure the precise docking of the heat pump system components with the inner tank to maintain the efficient operation of the whole machine.

[0003] In existing liner support positioning technology, simple fixing molds are often used to position the support. These molds are usually pre-designed and manufactured according to specific product models. The principle is to place the liner support in a specific position through fixing grooves or protrusions on the mold, and then perform welding operations. This method can achieve the positioning of the liner support to a certain extent, but it has great limitations in practical applications.

[0004] However, existing technologies have significant problems. In the early stages of product development, the solutions often need to be constantly adjusted, and there are many uncertainties in the product's structure and assembly. The welding positions of the inner tank support and the inner tank often need to be adjusted multiple times. However, the existing simple fixed mold positioning method cannot meet the needs of such position adjustments, resulting in inaccurate positioning of the inner tank support. This not only poses risks to the direct mass production of welding fixtures and easily leads to repeated modifications to the welding equipment, but also seriously affects the production schedule and wastes human and material resources. Therefore, a positioning fixture for the water heater inner tank support is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a positioning fixture for the inner tank support of a water heater, which improves the problem that traditional positioning fixtures in the prior art cannot flexibly adjust the position of the support, resulting in a lack of flexibility in the fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water heater inner tank support positioning fixture includes a water heater inner tank and an inner tank support. Multiple connecting pipes are fixedly connected inside the water heater inner tank, and a positioning component is provided on the outer wall of the water heater inner tank.

[0008] The positioning component includes a positioning frame, one side of which is slidably connected to the outer wall of the water heater inner tank. A support pad is fixedly connected to one side of the positioning frame, and the support pad is in contact with the outer wall of the water heater inner tank. Multiple connecting blocks are fixedly connected inside the positioning frame, and limit blocks are slidably connected inside each connecting block. A spring is provided on one side of each limit block, with one end of the spring fixedly connected to the side wall of the limit block and the other end fixedly connected to the inner wall of the connecting block. A limit ball is fixedly connected to one side of each limit block. Limit grooves are formed inside each inner tank support, and the limit ball fits into the limit groove. Multiple connecting components are provided on one side of the positioning frame.

[0009] As a further description of the above technical solution:

[0010] The plurality of connecting components include a support plate and a support disk, one side of the support plate being fixedly connected to one side of the positioning frame, and the outer wall of the support disk being fixedly connected to the other side of the support plate.

[0011] As a further description of the above technical solution:

[0012] The support plate is rotatably connected to a first connecting rod, and the support plate is rotatably connected to a second connecting rod.

[0013] As a further description of the above technical solution:

[0014] A locking plate is fixedly connected to the outer wall of the first connecting rod, and a locking plate is fixedly connected to the outer wall of the second connecting rod. The support plate is made of plastic.

[0015] As a further description of the above technical solution:

[0016] Both the first and second locking plates are made of rubber, and both the first and second locking plates are in contact with the outer wall of the connecting pipe.

[0017] As a further description of the above technical solution:

[0018] Both the first and second locking plates have a transmission disc fixedly connected to their outer walls, and an elastic gasket is provided on one side of the transmission disc.

[0019] As a further description of the above technical solution:

[0020] One end of the elastic pad is fixedly connected to the side wall of the support plate, and the other end is fixedly connected to the side wall of the transmission disc.

[0021] As a further description of the above technical solution:

[0022] Both the first and second locking plates have multiple anti-slip grooves inside.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by inserting the inner tank support into the positioning frame, it compresses the limiting ball, which further causes the spring to undergo elastic deformation. The elastic deformation of the spring provides a reverse force to the limiting ball, thereby limiting the inner tank support. At the same time, by pulling the inner tank support, the operator can make the inner tank support slide inside the positioning frame, thereby achieving the effect of freely adjusting the welding position of the inner tank support. This solves the problem of difficulty in adjusting the welding position of the inner tank support and the inner tank, and improves the positioning and adjustment efficiency in the welding process of the water heater.

[0025] 2. In this utility model, by squeezing the connecting pipe into the gap between the first and second locking plates, a squeezing force is generated during the locking process, causing the first and second locking plates to deflect. The movement of the first and second locking plates causes the elastic gasket to deform elastically. The elastic deformation of the elastic gasket provides a reverse force to the first and second locking plates, making the first and second locking plates tightly locked to the outer wall of the connecting pipe. This achieves the effect of quickly installing the positioning component, solving the problem that the positioning component cannot be quickly fixed to the inner tank of the water heater, and providing convenience and stability of the tooling.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a water heater inner tank support positioning fixture, which includes a water heater inner tank 1 and an inner tank support 2. Multiple connecting pipes 3 are fixedly connected inside the water heater inner tank 1. A positioning component is provided on the outer wall of the water heater inner tank 1. The positioning component can realize precise positioning and dynamic adjustment between the inner tank support 2 and the water heater inner tank 1.

[0035] The positioning assembly includes a positioning frame 4, one side of which is slidably connected to the outer wall of the inner tank 1 of the water heater. A support pad 5, made of polyurethane, is fixedly connected to one side of the positioning frame 4. This support pad 5 can fit tightly against the curved surface of the outer wall of the inner tank 1, providing support while preventing scratches. The support pad 5 fits snugly against the outer wall of the inner tank 1. Multiple connecting blocks 7 are fixedly connected inside the positioning frame 4. Limit blocks 8 are slidably connected inside each connecting block 7. The function of the limit blocks 8 is to limit the movement of the spring 9, ensuring that the spring 9 does not move excessively and cause damage. Simultaneously, it can transmit power, compressing the spring 9 to cause elastic deformation. A spring is provided on one side of each limit block 8. 9. The function of spring 9 is to provide elastic support for the limiting ball 10 and provide elastic restoring force to ensure the engagement of the limiting ball 10 with the limiting groove 6. One end of spring 9 is fixedly connected to the side wall of the limiting block 8, and the other end is fixedly connected to the inner wall of the connecting block 7. Limiting balls 10 are fixedly connected to one side of the limiting block 8. Limiting grooves 6 are opened inside the inner liner bracket 2. The limiting ball 10 and the limiting groove 6 fit together. Through the cooperation of the limiting ball 10 and the limiting groove 6, the stability of the inner liner bracket 2 can be ensured, and it can be guaranteed that it will not be displaced during welding. Multiple connecting components are provided on one side of the positioning frame 4. The connecting components are used to facilitate the operator to quickly install the positioning frame 4.

[0036] Specifically, when using this bracket positioning fixture, the operator first installs the inner tank bracket 2 inside the positioning frame 4. The function of the inner tank bracket 2 is to support and fix the position of the water heater inner tank 1. Its cooperation with the positioning frame 4 ensures that the inner tank bracket 2 can be accurately positioned on the outer wall of the water heater inner tank 1. At this time, the outer wall of the inner tank bracket 2 will contact the limiting ball 10. When the operator continues to install the inner tank bracket 2 into the positioning frame 4, this contact generates a squeezing force. Under the action of this squeezing force, the limiting ball 10 retracts into the connecting block 7, restricting the position of the inner tank bracket 2 and ensuring that it is stable and immobile. Through the contraction movement of the limiting ball 10, the limiting block 8 slides inside the connecting block 7, thereby squeezing the spring 9, causing the spring 9 to undergo elastic deformation and store elastic potential energy. The restoring force of the spring 9 provides a reverse force for the limiting ball 10 in subsequent operations, so that the limiting ball 10 accurately engages in the limiting groove 6, completing the precise locking of the position of the inner tank bracket 2. This process ensures the stability and accuracy of the inner liner support 2 during welding. When the position of the inner liner support 2 needs to be adjusted, the operator only needs to pull the inner liner support 2 to adjust its position within the gap of the positioning frame 4, thus providing flexibility to meet different tooling requirements. This ensures that the tooling can not only be stably positioned, but also easily adjusted, increasing the convenience of use.

[0037] Reference Figure 4 and Figure 5 The multiple connecting components include a support plate 11 and a support disk 12. One side of the support plate 11 is fixedly connected to one side of the positioning frame 4, and the outer wall of the support disk 12 is fixedly connected to the other side of the support plate 11. The function of the support plate 11 and the support disk 12 in the connecting components is to provide stable support and connection, ensuring the stable use of the connecting components. A connecting rod 13 is rotatably connected inside the support disk 12, and a connecting rod 14 is rotatably connected inside the support disk 12. The outer wall of the connecting rod 13 is fixedly connected to... The outer wall of the connecting rod 14 is fixedly connected to the locking plate 15 and the connecting plate 16. The support plate 11 is made of plastic, while the locking plates 15 and 16 are made of rubber. The rubber material of the locking plates 15 and 16 ensures that they can be tightly locked with the connecting pipe 3, thereby ensuring the installation stability of the positioning frame 4 and preventing the connecting pipe 3 from being damaged by extrusion. Both the locking plates 15 and 16 are in contact with the outer wall of the connecting pipe 3.

[0038] Specifically, when it is necessary to fix the positioning bracket 4 to the outer wall of the inner tank 1 of the water heater, the operator will align one side of the positioning bracket 4 with the connecting pipe 3 and then apply pressure. At this time, the connecting pipe 3 will be inserted into the gap between the first locking plate 15 and the second locking plate 16, causing the first locking plate 15 and the second locking plate 16 to deflect synchronously. At this time, the movement of the first locking plate 15 and the second locking plate 16 will further drive the transmission disc 17 to squeeze the elastic pad 18, thereby causing the elastic pad 18 to undergo elastic deformation and store elastic potential energy.

[0039] Reference Figure 4 and Figure 5 Both the first snap-fit ​​plate 15 and the second snap-fit ​​plate 16 have a transmission disc 17 fixedly connected to their outer walls. The transmission disc 17 is used to further transmit power, thereby driving the elastic pad 18 to be squeezed and deformed. An elastic pad 18 is provided on one side of the transmission disc 17. The elastic pad 18 is used to provide elastic restoring force and reverse force for the first snap-fit ​​plate 15 and the second snap-fit ​​plate 16, ensuring that they can quickly return to their original position after deflection. One end of the elastic pad 18 is fixedly connected to the side wall of the support plate 11, and the other end is fixedly connected to the side wall of the transmission disc 17. Both the first snap-fit ​​plate 15 and the second snap-fit ​​plate 16 have multiple anti-slip grooves 19 inside to increase friction and further improve the installation stability of the components.

[0040] Specifically, further, the elastic restoring force generated by the elastic gasket 18 during the recovery process provides elastic support for the first locking plate 15 and the second locking plate 16, ensuring that the first locking plate 15 and the second locking plate 16 can tightly fit against the outer wall of the connecting pipe 3, thereby realizing the rapid installation of the positioning frame 4. Through the cooperation of the first locking plate 15 and the second locking plate 16, the positioning frame 4 is guaranteed to remain stable when fixed, avoiding the displacement of the positioning frame 4 due to pressure or improper operation, and further improving the accuracy and reliability of the entire positioning fixture.

[0041] Working Principle: When using this bracket positioning fixture, the operator first installs the inner tank bracket 2 inside the positioning frame 4. Then, the positioning frame 4 is placed against the outer wall of the water heater inner tank 1. When the inner tank bracket 2 is installed inside the positioning frame 4, the outer wall of the inner tank bracket 2 contacts the limiting ball 10, thereby generating a compressive force. Under the action of the compressive force, the limiting ball 10 contracts into the connecting block 7. The contraction movement of the limiting ball 10 drives the limiting block 8 to slide inside the connecting block 7, thereby further compressing the spring 9, causing the spring 9 to undergo elastic deformation and store elastic potential energy, providing a reverse force for the limiting ball 10, pushing the limiting ball 10 into the limiting groove 6, thereby locking the position of the inner tank bracket 2 and ensuring the accuracy of the position of the inner tank bracket 2 during the welding process. When it is necessary to adjust the position of the inner tank bracket 2, the operator only needs to pull the inner tank bracket 2 to make the inner tank bracket 2 move within the positioning frame 4. The adjustable gap position provides flexibility for the tooling. When it is necessary to fix the positioning frame 4 to the outer wall of the inner tank 1 of the water heater, the operator aligns one side of the positioning frame 4 with the connecting pipe 3 and then presses the positioning frame 4. Under the pressure, the connecting pipe 3 is inserted into the gap between the first locking plate 15 and the second locking plate 16, causing the first locking plate 15 and the second locking plate 16 to deflect synchronously. The movement of the first locking plate 15 and the second locking plate 16 will further drive the transmission disc 17 to squeeze the elastic pad 18, causing the elastic pad 18 to undergo elastic deformation and store elastic potential energy. The elastic restoring force of the elastic pad 18 provides elastic support for the first locking plate 15 and the second locking plate 16, ensuring that the first locking plate 15 and the second locking plate 16 can be tightly attached to the outer wall of the connecting pipe 3, thereby achieving the function of quickly installing the positioning frame 4 and ensuring that the positioning frame 4 can remain stable during the positioning process, preventing the positioning frame 4 from shifting.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
