Description

Technical Field

[0001] This application relates to the field of diameter measuring instruments, and in particular to a diameter measuring instrument with a storage function. Background Technology

[0002] A diameter gauge is a precision instrument used to accurately measure the diameter of an object, and is mainly used for dimensional inspection in industrial production and scientific research.

[0003] When used in the metal processing and wire and cable industries, there is always a large amount of dust or floating matter in the air. The dust and floating matter in the air can easily affect the optical lens and sensor accuracy of the diameter measuring instrument. Therefore, when the diameter measuring instrument is not in use, it is best to store it to reduce the long-term contact between the diameter measuring instrument and the dust and floating matter in the surrounding environment. Therefore, there is a need for a diameter measuring instrument with storage function. Utility Model Content

[0004] To reduce the contact between the diameter gauge and dust and floating objects in the surrounding environment when the diameter gauge is not in use, this application provides a diameter gauge with a storage function.

[0005] This application provides a diameter measuring instrument with a storage function, which adopts the following technical solution: A diameter measuring instrument with a storage function includes a diameter measuring instrument body, two covers and a locking assembly. The two covers are located on both sides of the diameter measuring instrument body. The covers are rotatably connected to the diameter measuring instrument body along a horizontal direction that is perpendicular to the distribution direction of the two covers. When the two covers are in contact with each other, a sealed cavity is formed inside. The diameter measuring instrument body is located in the sealed cavity. The locking assembly is used to keep the two covers in contact.

[0006] By adopting the above technical solution, the two covers connected by rotation on both sides of the diameter measuring instrument body can fit together to form a sealed cavity when not in use, completely accommodating the diameter measuring instrument body. Combined with the locking component to fix the fit, it effectively isolates dust and floating objects in the surrounding environment, avoids prolonged contact between the optical lens and sensor and pollutants, ensures the measurement accuracy of the diameter measuring instrument, and at the same time achieves convenient storage function, adapting to the dusty usage scenarios in industrial production.

[0007] Optionally, the locking assembly includes a rotating plate, a snap-fit ​​block, a limiting block, and a limiting member. The rotating plate is rotatably connected to one of the covers, and the rotation axis of the rotating plate is parallel to the rotation axis of the cover. The snap-fit ​​block is disposed on the other cover and has a receiving groove. The limiting block is disposed on the rotating plate and is used to insert into the receiving groove. The limiting member is used to prevent the limiting block from disengaging from the receiving groove.

[0008] By adopting the above technical solution, the locking component provides reliable fixation for the fit of the two covers through the cooperation of the rotating plate, the snap-fit ​​block, the limiting block and the limiting component. The rotation direction of the rotating plate is parallel to the rotation axis of the cover, and the operation process is smooth. After the limiting block is inserted into the receiving groove of the snap-fit ​​block, it is limited by the limiting component, which can prevent the cover from being accidentally loosened in the storage state, ensure the sealing of the sealed cavity, and further improve the dust protection effect.

[0009] Optionally, the limiting component includes a limiting rod and a limiting spring. The limiting block has a limiting groove. The limiting rod is slidably connected to the snap-fit ​​block. The limiting spring is used for the limiting rod to pass into the limiting groove.

[0010] By adopting the above technical solution, the limiting component uses a combination of a limiting rod and a limiting spring. The elastic force of the limiting spring pushes the limiting rod into the limiting groove of the limiting block, thereby achieving automatic locking of the limiting block. The structure is simple and the locking response is fast. Fixing can be completed without additional complicated operations, while ensuring the stability of the locking and preventing the limiting block from dislodging from the receiving groove and causing the cover to open.

[0011] Optionally, the locking assembly further includes a coil spring for driving the rotating plate to rotate away from the locking block.

[0012] By adopting the above technical solution, the coil spring can drive the rotating plate to rotate away from the locking block. After the limiting component is unlocked, the rotating plate can automatically reset without manual prying, which simplifies the unlocking operation process, improves the ease of use, and at the same time reduces the long-term pressure of the rotating plate on the locking block, extending the service life of the locking component.

[0013] Optionally, the cover is provided with a handle for easy gripping.

[0014] By adopting the above technical solution, the handle on the cover makes it easy for users to hold and carry, improving the portability of the diameter measuring instrument. Whether it is moving it in the storage state or adjusting its position during use, it is more labor-saving and convenient, and it meets the needs of mobile use in multiple scenarios in industrial production.

[0015] Optionally, the housing is provided with shock-absorbing sponge, which is attached to the diameter measuring instrument body, and the shock-absorbing sponges in the two housings are attached to each other.

[0016] By adopting the above technical solution, the shock-absorbing sponge inside the cover fits into the diameter measuring instrument body, and the shock-absorbing sponges of the two covers fit together, which can form a buffer protection for the diameter measuring instrument body, reduce the vibration and impact during carrying or storage, avoid damage to internal precision components, and further fill the gap between the cover and the body, improving the dustproof and sealing effect of the sealed cavity.

[0017] Optionally, the contact surfaces of the two shock-absorbing foams are zigzag-shaped.

[0018] By adopting the above technical solution, the contact surfaces of the two shock-absorbing sponges are designed in a zigzag shape, which increases the contact area and tightness between the sponges, improves the cushioning and shock absorption effect, and at the same time, the zigzag structure can enhance the friction between the sponges, prevent the two covers from sliding relative to each other when stored, and further ensure the stability and dustproof sealing of the sealed cavity.

[0019] Optionally, a threaded hole for connecting an auxiliary support is provided at the bottom of the diameter measuring instrument body.

[0020] By adopting the above technical solution, the threaded hole at the bottom of the diameter measuring instrument can be used to connect to the auxiliary bracket, so that the diameter measuring instrument can be fixed on the bracket according to the usage requirements, improving the stability during measurement, adapting to the measurement needs of different heights and different scenarios, expanding the application range of the diameter measuring instrument, and at the same time not affecting the storage function of the cover.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By configuring the diameter measuring instrument body, two covers, and a locking assembly, the two covers are located on either side of the diameter measuring instrument body and rotate to connect to the body in a specific direction. When the two covers are in contact with each other, a sealed cavity is formed inside to accommodate the diameter measuring instrument body. The locking assembly then secures the covers in place. This effectively isolates dust and floating debris from the metal processing and wire and cable industry environments, preventing them from affecting the accuracy of the diameter measuring instrument's optical lens and sensor. It also allows for convenient storage of the diameter measuring instrument. 2. The rotating plate, snap-fit ​​block, limit block and limiting component are used to provide reliable locking for the cover to fit; the limiting component structure is optimized, and the limiting spring pushes the limiting rod to automatically enter the limiting groove, which simplifies the operation and improves the locking reliability; a coil spring is added to drive the rotating plate to automatically reset, which simplifies the unlocking process and reduces the extrusion wear of the components. 3. Shock-absorbing sponge is installed inside the cover to fit the diameter measuring instrument body, and the shock-absorbing sponge of the two covers fits together. This can not only buffer vibrations when carrying or storing the instrument and protect the precision components inside, but also fill the gap between the cover and the body to enhance the sealing of the sealed cavity.

The limiting groove 331 extends along the length of the diameter measuring instrument body 1 and passes through the limiting block 33.

[0030] Reference Figure 3 and Figure 4 The snap-fit ​​block 32 has a receiving groove 321 on the side opposite to the cover 2. The receiving groove 321 extends from the snap-fit ​​block 32 to the cover 2. The limiting block 33 is used to insert into the receiving groove 321.

The cover 2 is also provided with a handle 5, which is rotatably connected to the cover 2 along the length direction of the diameter measuring instrument.

[0031] The implementation principle of a diameter measuring instrument with storage function in this application embodiment is as follows: When not in use, two covers 2 distributed along the thickness direction of the diameter measuring instrument body 1 are rotated along the length direction parallel to the body until they fit together to form a sealed cavity to accommodate the diameter measuring instrument body 1. At the same time, the state of the covers 2 is fixed by two locking components 3 distributed along the length direction of the body. When locked, the rotating plate 31 rotates around the axis parallel to the length direction of the body, so that the limiting block 33 is inserted into the receiving groove 321 of the snap block 32 of the other cover 2. The limiting spring 342 in the limiting member 34 pushes the limiting rod 341 into the limiting groove 331 of the limiting block 33 to prevent the limiting block 33 from disengaging. The coil spring 35 can drive the rotating plate 31 to automatically reset when unlocking.

[0032] The shock-absorbing sponge 4 inside the cover 2 fits the main body to buffer vibration and enhance the cavity sealing. The handle 5 on the cover 2 makes it easy to carry. The threaded hole 11 at the bottom of the main body can be connected to an auxiliary bracket to adapt to different measurement scenarios, so as to achieve dustproof storage while ensuring the accuracy and ease of use of the diameter measuring instrument main body 1.
