[0001] The utility model relates to the technical field of detection devices, in particular to a seesaw type detection mechanism. Background Art

[0002] During the production or processing of products, it is necessary to inspect specific positions of the products to determine whether the specific positions of the products are qualified, such as whether the depth of the blind hole is qualified or whether the depth of the nut screwed into the bolt is qualified. Among the existing patents, the Chinese patent document with application number 202223482852.8 discloses a position and surface contour lever detection mechanism, including a platform, a first support seat is provided on the top left side of the platform, a second support seat is provided in the middle of the top, and a meter support is provided on the top right side, and a lever is rotatably connected to the U-shaped groove on the top of the second support seat through a rotating shaft; a first detection block is fixedly provided in the open groove at the left end of the lever, a pin seat is fixedly provided on the top of the first support seat, a position detection pin for matching with the part for detection is inserted on the pin seat, a connecting block is fixedly sleeved on the outer side of the position detection pin, a surface detection pin matching with the part is provided on the top of the connecting block, a first baffle is fixedly provided on the bottom of the position detection pin through a nut, and a first spring is sleeved on the outer side of the position detection pin between the first baffle and the pin seat, and a second baffle with a limited position on the top of the first baffle and sleeved on the outside of the first spring is fixedly provided on the left side of the top end of the lever. Although the patent document uses a lever to detect the position and surface contour of the product, it has a complex structure and high cost, which is not conducive to popularization and use, and it is impossible to quickly determine whether the product is qualified simply by naked eye observation. Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

The utility model has the advantages of simple structure, low cost, convenient operation, high detection efficiency, being conducive to popularization and use, and being able to quickly judge whether a product is qualified by naked eye observation.

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0017] like Figures 1 to 3 As shown, the utility model provides a simple seesaw type detection mechanism, which includes a base plate 1, a fixed seat 2, a seesaw rod 3, a tension spring 4, a mounting seat 5, a detection assembly 6 and a determination reference member 7. The mounting seat 5 and the fixed seat 2 are both mounted on the base plate 1, the detection assembly 6 slides up and down through the mounting seat 5, the middle part of the seesaw rod 3 is rotatably connected with the fixed seat 2, the detection assembly 6 is located above one end of the seesaw rod 3, and one end of the seesaw rod 3 is used to abut against the bottom end of the detection assembly 6, the determination reference member 7 is mounted on the base plate 1 and is located below the other end of the seesaw rod 3, and the determination reference member 7 is used to abut against the other end of the seesaw rod 3, one end of the tension spring 4 is connected to the fixed seat 2, and the other end of the tension spring 4 is connected to one end of the seesaw rod 3 close to the detection assembly 6; in normal state, the elastic force of the tension spring 4 makes the seesaw rod 3 in a balanced state. Specifically, the distance from the detection component 6 to the fixed base 2 is smaller than the distance from the determination reference piece 7 to the fixed base 2 , that is, the distance from the fixed base 2 to one end of the seesaw rod 3 is smaller than the distance from the fixed base 2 to the other end of the seesaw rod 3 .

[0018] In actual application, the product is fixed above the utility model, and the position to be detected of the product is located above the detection component 6, and the distance between the position to be detected of the product and the top of the detection component 6 is set, and the seesaw rod 3 is in a horizontal balance state under the elastic force of the tension spring 4; when the position to be detected of the product is detected, a downward pressure is applied to the end of the seesaw rod 3 away from the detection component 6, so that the seesaw rod 3 rotates, and one end of the rotating seesaw rod 3 will move upward and contact the bottom end of the detection component 6, so that the detection component 6 moves up relative to the mounting seat 5, and the detection component 6 detects the position to be detected of the product. In the process of the detection component 6 detecting the position to be detected of the product, when the other end of the seesaw rod 3 can contact the determination reference part 7, it proves that the position to be detected of the product is qualified; when the other end of the seesaw rod 3 cannot contact the determination reference part 7, it proves that the position to be detected of the product is unqualified. After the detection is completed, the force on the seesaw rod 3 is released, and the seesaw rod 3 restores the balance state under the elastic force of the tension spring 4, so that the utility model can detect the next product. The utility model has the advantages of simple structure, low cost, convenient operation, high detection efficiency, and is conducive to popularization and use. It can quickly judge whether a product is qualified by naked eye observation, avoiding the need to carefully check the readings displayed by the detection instrument (such as micrometer, etc.).

[0019] In this embodiment, the detection assembly 6 includes a guide sleeve 8 embedded in the mounting seat 5, a detection member 9 slidingly passing through the guide sleeve 8, a guide spring column 10 installed at the bottom end of the detection member 9, and a spring 11 sleeved outside the guide spring column 10, the two ends of the spring 11 respectively contact the end plate of the guide spring column 10 and the mounting seat 5, and one end of the seesaw rod 3 is used to contact the bottom surface of the end plate of the guide spring column 10. Specifically, the detection assembly 6 also includes a limit block 12 installed on the mounting seat 5, and a sliding limit groove 13 is opened on the side wall of the detection member 9. The sliding limit groove 13 extends along the length direction of the detection member 9, and one end of the limit block 12 protrudes into the sliding limit groove 13.

[0020] In normal state, the spring 11 is in an extended state, the limit block 12 is in contact with the top wall of the sliding limit groove 13, and the detection piece 9 is in a low position; when one end of the seesaw rod 3 rotates upward, one end of the seesaw rod 3 is in contact with the guide spring column 10, so that the guide spring column 10 and the detection piece 9 move upward relative to the guide sleeve 8, and the guide spring column 10 compresses the spring 11 so that the detection piece 9 can detect the position to be detected of the product; after the detection is completed, the seesaw rod 3 releases the force on the guide spring column 10, and under the action of the rebound force of the spring 11, the guide spring column 10 and the detection piece 9 move downward and reset until the limit block 12 is in contact with the bottom wall of the sliding limit groove 13, proving that the detection piece 9 is reset in place, so as to facilitate the detection of the next product.

[0021] In this embodiment, the detection member 9 is a pin or a pin sleeve. When the detection member 9 is a pin, the pin can detect the depth of the blind hole on the product. During the detection, the pin is gradually inserted into the blind hole. When the other end of the seesaw rod 3 can collide with the determination reference member 7, it is proved that the depth of the blind hole meets the requirement, and the blind hole of the product is qualified. Otherwise, the pin conflicts with the bottom wall of the blind hole of the product, so that the other end of the seesaw rod 3 cannot collide with the determination reference member 7, which proves that the blind hole of the product is unqualified. When the detection member 9 is a pin sleeve, the pin sleeve can detect the nut screwed into the bolt on the product. During the detection, the pin sleeve is gradually sleeved outside the bolt. When the other end of the seesaw rod 3 can collide with the determination reference member 7, it is proved that the depth of the nut screwed in meets the requirement, and the bolt and nut assembly of the product is qualified. Otherwise, the pin sleeve conflicts with the nut, so that the other end of the seesaw rod 3 cannot collide with the determination reference member 7, which proves that the bolt and nut assembly of the product is unqualified.

[0022] Specifically, the guide spring column 10 is threadedly connected to the detection member 9. This structural design ensures that the connection between the guide spring column 10 and the detection member 9 is firm and convenient for disassembly, assembly and maintenance.

[0023] In this embodiment, the determination reference member 7 is a determination screw, which is threadedly connected to the bottom plate 1. According to the detection requirements of different products, the determination screw is screwed to change the height of the determination screw, so as to meet the requirements of rapid detection of different products.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
