Detailed Implementation

[0028] 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.

[0029] The core of this utility model is to provide a test fixture for the protection level of lock-type products of various specifications, which can be used for products of different specifications, and the disassembly and assembly of this device with the product is simple and convenient. Another core aspect of this utility model is to provide a testing device including the above-mentioned test fixture for the protection level of lock-type products of various specifications.

[0030] Please refer to Figure 1 and Figure 2 This specific embodiment provides a testing fixture for the protection level of locks of various specifications, including:

[0031] The base 1 has a threaded rod 11 at its center;

[0032] A sealing gasket 2 is provided on the top of the base 1, and the sealing gasket 2 has a through hole 21 for the threaded rod 11 to pass through;

[0033] The upper cover 3 is used to clamp the product 4 with the base 1. The upper cover 3 is provided with an assembly hole 31 for assembly and connection with the threaded rod 11. The bottom of the upper cover 3 protrudes downward and is provided with an assembly part 32 for assembly with products 4 of different sizes. The assembly part 32 includes at least two circular bosses 33 with a height difference, and the diameter of each circular boss 33 gradually decreases from top to bottom.

[0034] It should be noted that the bottom of the top cover 3 protrudes downward to provide an assembly part 32, and the assembly part 32 includes at least two circular bosses 33 with a height difference, and the diameter of each circular boss 33 gradually decreases from top to bottom, so that the circular bosses 33 of the assembly part 32 can be sealed and assembled with products 4 of different sizes, thereby making the device compatible with various models of products 4 and reducing the types of fixtures.

[0035] like Figure 3 As shown, this is an assembly diagram of a large-diameter product 4 and a multi-specification lockable product protection level test fixture. At this point, the sealing element 5, used to seal the top of product 4, and the end of the largest outer diameter surface of the upper cover 3 are in contact for sealing. (As shown...) Figure 4 As shown, it is an assembly diagram of product 4 with a small diameter and a test fixture for the protection level of multiple specifications of lockable products. At this time, the sealing element 5 used to seal the top of product 4 and the end of the smallest outer diameter surface (that is, the smallest diameter, the lowest circular boss 33) of the top cover 3 abut and seal.

[0036] In practical applications, the shape, structure, size, material, and position of the base 1, sealing gasket 2, and top cover 3 can be determined according to the actual situation and needs.

[0037] When using the interlocking multi-specification product protection level test fixture provided by this utility model, firstly, the through hole 21 of the sealing gasket 2 can be passed through the threaded rod 11 of the base 1, so that the sealing gasket 2 is located at the top of the base 1. Then, the product 4 is placed on the sealing gasket 2 through the threaded rod 11, so that the bottom end of the product 4 is sealed by the sealing gasket 2. After that, the sealing element 5 of the product 4 and the top end of the product 4 can be sealed and connected. Finally, the assembly hole 31 of the upper cover 3 is aligned with the threaded rod 11 and assembled, and then the upper cover 3 is tightened so that the upper cover 3 and the threaded rod 11 are threadedly connected until the assembly part 32 of the upper cover 3 and the sealing element 5 abut.

[0038] Because the bottom of the top cover 3 protrudes downwards and has an assembly part 32 for assembling with products 4 of different sizes, the top of products 4 of different sizes can be abutted by the assembly part 32, and the bottom of products 4 can be sealed by the sealing gasket 2. That is, this device can be adapted to various models of products 4, effectively reducing the manufacturing cost of the device. Moreover, the base 1 is provided with a sealing gasket 2. If it is necessary to replace the product 4, it is only necessary to insert the product 4, the sealing element 5 and the top cover 3 in sequence. The operation is simple and the disassembly and assembly are convenient.

[0039] In summary, the interlocking multi-specification product protection level testing fixture provided by this utility model can be used for products 4 of different specifications, and the disassembly and assembly operation between this device and product 4 is simple and convenient.

[0040] In one embodiment, the diameter of the sealing gasket 2 is greater than or equal to the maximum diameter of the top cover 3, and the diameter of the sealing gasket 2 is less than or equal to the diameter of the base 1. By setting a large-area sealing gasket 2 on the base 1 to accommodate different models of products 4, the bottom of different models of products 4 is sealed. Combined with the sealing element 5 of the product 4 and the seal of the top cover 3, the sealing position of the product 4 can be made more reliable, reducing the risk of sealing failure of the product 4 and avoiding misjudgment of leakage due to deformation or poor sealing of the product 4.

[0041] In one embodiment, the sealing gasket 2 includes a rubber gasket or a silicone gasket. By fixing the sealing gasket 2 on the base 1, different models of products 4 can be installed on the sealing gasket 2 to seal the bottom of the product 4. That is, the base 1 of this device is equipped with a sealing gasket 2, and there is no need to repeatedly install the sealing gasket 2, making the installation of the product 4 more convenient and the locking operation between the device and the product 4 easier. Only the top cover 3 needs to be tightened last, so that the assembly part 32 of the top cover 3 and the sealing element 5 of the product 4 abut and seal. This device adopts a locking sealing structure, which can reduce the installation steps of the product 4 and achieve quick locking of the product 4 and the device.

[0042] In one embodiment, such as Figure 3 and Figure 4 As shown, the assembly hole 31 includes a first threaded hole 34 and a second threaded hole 35 that are threadedly connected to the threaded rod 11. The diameter of the second threaded hole 35 is larger than the diameter of the first threaded hole 34. The second threaded hole 35 is used for threaded connection with a tightening tool.

[0043] It should be noted that the threaded rod 11 at the center of the base 1 is used to cooperate with the upper cover 3. The upper cover 3 can be designed with multiple circular bosses 33 with different heights and diameters according to the series of products 4, which can form a stepped surface (which is a sealing surface). During testing, the product 4 with the sealing element 5 installed is put into the threaded rod 11 of the base 1. The inner hole of the product 4 can pass through the threaded rod 11 until the bottom of the product 4 is sealed and connected with the sealing gasket 2, thus achieving the sealing operation of the bottom end of the product 4. After that, the first threaded hole 34 of the upper cover 3 is aligned with the threaded rod 11 and inserted, and the tightening tool is aligned with the second threaded hole 35 and inserted. The tightening tool is used to seal the second threaded hole 35 and drive the upper cover 3 to rotate around the threaded rod 11. At this time, the upper cover 3 and the threaded rod 11 are threadedly connected, and the upper cover 3 can also move down along the threaded rod 11, so that the assembly part 32 at the bottom of the upper cover 3 and the sealing element 5 at the top of the product 4 abut against each other, ensuring that the sealing element 5 effectively seals the top of the product 4, thus achieving the sealing operation of the top of the product 4.

[0044] This device is particularly suitable for waterproof testing scenarios involving products with small outer sealing surfaces and multiple specifications. By improving the fixture structure, this device can be adapted to multiple models of products and ensures reliable sealing of products 4, while also being easy to operate.

[0045] In one embodiment, such as Figure 2 As shown, the top of the upper cover 3 is provided with a long strip-shaped boss 36, and a second threaded hole 35 is provided in the long strip-shaped boss 36.

[0046] It should be noted that a long strip-shaped protrusion 36 is provided on the top of the upper cover 3. To facilitate the processing and manufacturing of the upper cover 3, a portion can be cut off from the front and rear ends of the top of the upper cover 3, so that the front and rear ends of the long strip-shaped protrusion 36 are vertical surfaces, and the left and right ends of the long strip-shaped protrusion 36 are arc surfaces. Furthermore, during the use of this device, the second threaded hole 35 in the second step surface needs to be threadedly connected to the tightening tool, so that the second threaded hole 35 is blocked, and it is convenient for the tightening tool to rotate the upper cover 3, so that the upper cover 3 moves up and down along the threaded rod 11 until the assembly part 32 at the bottom of the upper cover 3 and the end of the sealing element 5 of the product 4 abut against each other. At this time, the top of the product 4 is effectively sealed by the sealing element 5, and the bottom of the product 4 is effectively sealed by the sealing gasket 2.

[0047] In one embodiment, the assembly part 32, the upper cover 3, and the elongated boss 36 are integral structural components to facilitate the processing and manufacturing of the upper cover 3 and to ensure that the assembly part 32 and the elongated boss 36 of the upper cover 3 meet the usage requirements.

[0048] In addition to the aforementioned interlocking multi-specification product protection level test fixture, this utility model also provides a test device including the interlocking multi-specification product protection level test fixture disclosed in the above embodiments. For the structure of other parts of the test device, please refer to the prior art, which will not be repeated here.

[0049] In one embodiment, a sealing element 5 is further included for sealing one end of the product 4. The end of the sealing element 5 abuts against the end of the upper cover 3 of the multi-specification product protection level test fixture. That is, after the inner hole of the product 4 is inserted into the threaded rod 11, so that the bottom of the product 4 and the sealing gasket 2 are sealed together, the sealing element 5 can be inserted into the top of the product 4, and then the upper cover 3 is aligned with the threaded rod 11 and inserted, so that the mounting end of the upper cover 3 abuts against the end of the sealing element 5, thereby pressing the sealing element 5 and the top of the product 4 to achieve a seal at the top of the product 4.

[0050] It should be noted that the first threaded hole 34 and the second threaded hole 35 mentioned in this application are only distinguished by their different positions and do not have any order of precedence.

[0051] In addition, it should be noted that the orientation or positional relationship indicated by "upper" and "lower" in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
