Description

Technical Field

[0001] This utility model relates to the field of water heater testing fixtures, specifically to a testing fixture. Background Technology

[0002] A water heater is a device that heats water for domestic or commercial use, and is widely used for bathing, washing, and kitchen water use. A water heater typically includes a casing, as well as components such as a burner and a heat exchanger housed within the casing. The casing has multiple mounting holes, as well as an inlet and an outlet that connect to the heat exchanger. Cold water entering from the inlet is heated by the heat exchanger, and hot water is then output from the outlet.

[0003] After the water heater is manufactured, the positions of the connection holes, as well as the positions of the liquid inlet and outlet, need to be inspected to ensure that the positions of the multiple connection holes, as well as the positions of the liquid inlet and outlet, meet the design requirements. In the existing technology, measuring tools are usually used to measure the distance between the test holes, the liquid inlet and outlet and the reference edge or reference surface. The inspection time is long, the accuracy is limited, and the error is large due to the influence of human reading, which can easily lead to inaccurate test results. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] To address the technical problem in existing technologies where it is inconvenient to determine the positions of multiple connection holes on a water heater, as well as whether the inlet and outlet positions meet preset requirements, this solution provides a testing fixture. This fixture can detect the positions of the connection holes, as well as the inlet and outlet positions of the water heater, improving testing speed and accuracy, and ensuring the production quality of the water heater.

[0019] Please see Figures 1-4 , Figures 1-4 This invention provides a detection device for detecting the positions of connection hole a1, inlet end a2, and outlet end a3 of a water heater A. The device includes a detection platform 1, port detection components 2, multiple hole position detection components 3, and multiple test components 4. The port detection component 2 is mounted on the detection platform 1 and has two spaced-apart alignment portions 21. The multiple hole position detection components 3 are mounted on the detection platform 1 and have support ends 31 with detection holes 3a. The multiple test components 4 are mounted on the detection platform 1 and are detachably connected to the platform 1. When each support end 31 supports the water heater, and the inlet end and outlet end of the water heater correspond to the two alignment portions 21, the multiple test components 4 can be used to detect whether each detection hole 3a corresponds one-to-one with each connection hole.

[0020] In actual use, by placing water heater A on the test platform 1 and ensuring that multiple hole detection pieces 3 support water heater A, first determine whether the liquid inlet end a2 and liquid outlet end a3 of water heater A correspond to the two alignment parts 21 respectively. Then, remove the test piece 4 and use the test piece 4 to check whether each connection hole a1 of water heater A can correspond one-to-one with each detected hole 3a.

[0021] It should be noted that the port detection component 2 is not limited to a specific structure. In one embodiment, the port detection component 2 includes a mounting base 22, which is fixed on the detection platform 1. Both alignment parts 21 are slidably connected to the mounting base 22, and the two alignment parts 21 can be inserted into the inlet and outlet of the water heater, respectively.

[0022] Specifically, when water heater A is placed on test platform 1 and multiple hole detection elements 3 support water heater A, the liquid inlet and liquid outlet can be observed to be able to be inserted into the two alignment elements 21 respectively by pushing the alignment part 21 to slide relative to the mounting base 22.

[0023] It should be noted that, in one embodiment, the alignment part 21 includes a guide rod 211 and a positioning block 212. The guide rod 211 is slidably connected to the mounting base 22. One end of the guide rod 211 is fixedly connected to the positioning block 212, and a groove is provided on the positioning block 212, so that the liquid inlet end or liquid outlet end can be inserted into the groove.

[0024] In addition, based on the above scheme, the alignment part 21 also includes a compression spring 213, which is sleeved on the guide rod 211. One end of the compression spring 213 abuts against the protrusion at the other end of the guide rod 211, and the other end of the compression spring 213 abuts against the mounting base 22.

[0025] It is understandable that when the inlet or outlet is inserted into the groove of the positioning block 212, the operator can release the protrusion, and under the action of the compression spring 213, the positioning block 212 can automatically separate from the inlet or outlet.

[0026] It should be noted that, in one embodiment, the testing platform 1 is fixed with a plurality of seats 11, and the seats 11 are provided with insertion holes, through which the test piece 4 is inserted into the seats 11.

[0027] In one embodiment, the test piece 4 includes a grip 41, the end of which is provided with a column 42, which can pass through the insertion hole. The outer diameter of the column 42 is the same as the inner diameter of the connection hole and the detection hole 3a. The axis of the grip 41 coincides with the axis of the column 42, and the outer diameter of the grip 41 is larger than the outer diameter of the column 42. The grip 41 is provided with anti-slip texture.

[0028] It should be noted that water heater A has four connection holes a1, and there are four hole position detection elements 3 and four test elements 4. The hole position detection element 3 is not limited to a specific structure. It is only necessary to ensure that the hole position detection element 3 has a support end 31 and a detection hole 3a is opened on the support end 31. Specifically, the installation position of the hole position detection element 3 can be designed according to the actual situation, and the height of each support end and the inner diameter of the detection hole 3a can also be designed according to the actual situation. No other limitations are made here.

[0029] Furthermore, based on the above scheme, each end of the testing platform 1 is provided with a handle 12 for supporting the testing platform 1. The testing platform 1 is made of alloy plate. Of course, in other embodiments, the testing platform 1 can also be made of plastic plate.

[0030] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
