Description

Technical Field

[0001] This utility model belongs to the field of electric water heater technology, and in particular relates to a protective device for the outlet pipe of an anti-collision electric water heater. Background Technology

[0002] As a common household hot water supply device, the core function of an electric water heater is to provide users with constant-temperature hot water by heating the cold water in the inner tank. The outlet pipe, as a key component connecting the inner tank to external water terminals (such as shower heads and faucets), bears the responsibility of transporting high-temperature water for extended periods. However, the outlet pipe of an electric water heater is constantly exposed to complex operating conditions and is susceptible to external impacts, bending, or vibrations, leading to stress concentration at the interface.

[0003] Traditional protective structures often employ rigid fixing methods, lacking cushioning capabilities. With prolonged use, metal fatigue or plastic deformation can lead to loosening of interfaces and seal failure, resulting in leakage risks. Furthermore, the disassembly and assembly of existing protective devices require complex tools or multiple disassembly processes, resulting in low maintenance efficiency and potential secondary damage to the piping. Therefore, we provide a collision-resistant water outlet pipe protection device for electric water heaters to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for the outlet pipe of an anti-collision electric water heater. Through the cooperation of a buffer mechanism and a quick-release mechanism, it solves the problems of easy leakage at the outlet pipe and interface of the electric water heater in the prior art and the inconvenience of disassembling and assembling the protective structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a protective device for the outlet pipe of an anti-collision electric water heater, including a water heater connector. The bottom of the water heater connector is connected to the outlet pipe body, and a protective shell is provided on the surface of the outlet pipe body. A buffer mechanism is provided inside the protective shell, and the buffer mechanism includes a telescopic rod fixedly connected to the inside of the protective shell, an arc-shaped plate fixedly connected to the other end of the telescopic rod, and a first spring sleeved on the surface of the telescopic rod. A quick-release mechanism is provided on the surface of the protective shell, and the quick-release mechanism includes a pressing groove formed on the surface of the protective shell, a second spring fixedly connected to the inner cavity of the pressing groove, a pressing block fixedly connected to the other end of the second spring, a connecting rod fixedly connected to one side of the pressing block, a stop block fixedly connected to the other end of the connecting rod, and a fixing ring sleeved on the surface of the protective shell.

[0007] The present invention is further configured such that one end of the first spring is fixedly connected to the inner side of the protective shell, and the other end of the first spring is fixedly connected to one side of the arc plate. The two ends of the first spring are respectively fixed to the protective shell and the arc plate, so as to ensure that the buffer force is evenly transmitted when the spring is compressed, and to avoid the protection failure caused by the off-center load.

[0008] The present invention is further configured such that there are six arc-shaped plates arranged in a circular array, forming an annular buffer zone that evenly wraps the water outlet pipe body in multiple directions, thereby enhancing its resistance to bending.

[0009] The present invention is further configured such that the protective shell is composed of two half shells, and each half shell has a locking block fixedly connected to one side, and a locking groove adapted to the locking block is opened on the other side of the half shell. The protective shell is connected by the two half shells through the locking block and the locking groove. The split design makes it easy to wrap the installed pipeline, and the locking structure ensures a stable closure.

[0010] The present invention is further configured such that a limiting plate is fixedly connected to the surface of the protective shell, and there are two limiting plates, which are symmetrically arranged on the surface of the protective shell and abut against the fixing ring to prevent the fixing ring from axially displacing.

[0011] The present invention is further configured such that the cross-sectional shape of the stop block is trapezoidal, the inner diameter of the fixing ring is the same as the outer diameter of the protective shell, the trapezoidal cross-section of the stop block provides a self-locking function, and the inner diameter of the fixing ring matches the outer diameter of the protective shell to ensure that the quick-release mechanism fits tightly.

[0012] The present invention is further provided that a sealing ring is provided on the inner side of the protective shell. The sealing ring is made of elastic rubber. The elastic rubber sealing ring is provided on the inner side of the protective shell, filling the gap between the protective shell and the water outlet pipe, which is waterproof and dustproof, and at the same time helps to buffer vibration.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model combines six circumferentially arrayed arc plates with telescopic rod springs to form an annular buffer zone, which can absorb external force impacts from any direction and disperse stress into elastic potential energy, significantly reducing the risk of leakage caused by bending deformation at the interface. The protective shell adopts a split buckle structure design, combined with an elastic sealing ring, which can not only adapt to the wrapping needs of different pipe diameters, but also achieve waterproof and dustproof functions, further improving the protection effect at the interface.

[0015] 2. This utility model achieves quick installation and disassembly of the protective shell by using a trapezoidal stop and a fixing ring in a snap-fit ​​design, combined with a press-type unlocking design, without the need for tools, which facilitates daily maintenance or repair. At the same time, the cooperation between the fixing ring and the limiting plate ensures the stability of the protective shell installation.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1 Please see Figures 1-5This utility model is a protective device for the outlet pipe of an anti-collision electric water heater, including a water heater connector 1, with an outlet pipe body 2 connected to the bottom of the water heater connector 1, and a protective shell 3 provided on the surface of the outlet pipe body 2; a buffer mechanism is provided inside the protective shell 3, the buffer mechanism including a telescopic rod 4 fixedly connected to the inside of the protective shell 3, an arc-shaped plate 5 fixedly connected to the other end of the telescopic rod 4, and a first spring 6 sleeved on the surface of the telescopic rod 4; a quick-release mechanism is provided on the surface of the protective shell 3, the quick-release mechanism including a pressing groove 7 opened on the surface of the protective shell 3, a second spring 8 fixedly connected to the inner cavity of the pressing groove 7, a pressing block 9 fixedly connected to the other end of the second spring 8, a connecting rod 10 fixedly connected to one side of the pressing block 9, a stop block 11 fixedly connected to the other end of the connecting rod 10, and a fixing ring 12 sleeved on the surface of the protective shell 3.

[0026] Further details: The telescopic rod 4 is vertically fixed to the inner wall of the protective shell 3, and the end is fixedly connected to the arc plate 5. The first spring 6 is sleeved on the outside of the telescopic rod 4, and both ends are fixed to the protective shell 3 and the arc plate 5 respectively. When the water outlet pipe body 2 is bent by external force, the arc plate 5 is squeezed and pushes the telescopic rod 4 to retract. The spring is compressed to absorb energy, disperse the stress at the interface, and avoid leakage caused by long-term deformation. The pressing block 9 is elastically connected to the pressing groove 7 through the second spring 8. The connecting rod 10 is linked to the stop block 11 and the pressing block 9. During installation, the fixing ring 12 is sleeved on the outside of the protective shell 3. The trapezoidal cross-section design of the stop block 11 makes it easy for the fixing ring 12 to be inserted. When the pressing block 9 is pressed, the stop block 11 is disengaged from the groove, realizing quick disassembly.

[0027] Example 2 Please see Figures 1-5 Based on embodiment 1, one end of the first spring 6 is fixedly connected to the inner side of the protective shell 3, and the other end of the first spring 6 is fixedly connected to one side of the arc plate 5. There are six arc plates 5 arranged in a circumferential array. The protective shell 3 is composed of two half shells, and a locking block 13 is fixedly connected to one side of each half shell. A locking groove 14 adapted to the locking block 13 is opened on the other side of the half shell. Limiting plates 15 are fixedly connected to the surface of the protective shell 3. There are two limiting plates 15. The cross-sectional shape of the stop block 11 is trapezoidal. The inner diameter of the fixing ring 12 is the same as the outer diameter of the protective shell 3. A sealing ring 16 is provided on the inner side of the protective shell 3. The sealing ring 16 is made of elastic rubber.

[0028] Further details: The first spring 6 is fixed at both ends to the protective shell 3 and the arc plate 5 respectively, ensuring that the spring is compressed and the buffer force is transmitted evenly, avoiding the failure of protection caused by uneven load. The six arc plates 5 are arranged in a circumferential array to form an annular buffer zone, which evenly wraps the water outlet pipe body 2 in multiple directions, enhancing the bending resistance. The protective shell 3 is composed of two half shells connected by the interlocking of the locking block 13 and the locking groove 14. The split design makes it easy to wrap the installed pipe. The locking structure ensures a stable closure. The limiting plate 15 is symmetrically arranged on the surface of the protective shell 3 and abuts against the fixing ring 12 to prevent the axial displacement of the fixing ring 12. The trapezoidal cross section of the stop block 11 provides a self-locking function. The inner diameter of the fixing ring 12 matches the outer diameter of the protective shell 3 to ensure that the quick-release mechanism fits tightly. The elastic rubber sealing ring 16 is located on the inner side of the protective shell 3 to fill the gap between the protective shell 3 and the water outlet pipe, making it waterproof and dustproof, and at the same time assisting in buffering vibration.

[0029] The working principle of this utility model is as follows: When the water outlet pipe body 2 is subjected to external impact or bending, its surface contacts the arc plate 5 on the inner side of the protective shell 3. After being squeezed, the arc plate 5 pushes the telescopic rod 4 to contract towards the inner wall of the protective shell 3, and at the same time compresses the first spring 6. In this process, the impact energy is converted into the elastic potential energy of the spring and evenly distributed through the six circumferentially distributed arc plates 5, thereby avoiding stress concentration that could damage the connection between the water heater connector 1 and the water outlet pipe body 2, and effectively preventing the sealing failure of the interface due to long-term deformation.

[0030] When disassembling the protective shell 3, press the pressing blocks 9 on both sides simultaneously. The pressing blocks 9 move inward against the elastic force of the second spring 8, driving the stop block 11 to move through the connecting rod 10. At this time, the fixing ring 12 releases its axial restriction on the protective shell 3, allowing the two halves of the protective shell 3 to be separated along the docking direction of the locking block 13 and the locking groove 14, achieving quick disassembly. During installation, after wrapping the half shell around the water outlet pipe body 2 and clamping it, push down the fixing ring 12 so that its inner wall slope contacts the trapezoidal section of the stop block 11. The stop block 11 is briefly retracted under pressure. When the fixing ring 12 moves to the limiting plate 15, the stop block 11 pops out under the action of the second spring 8, limiting the fixing ring 12.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
