Description

Technical Field

[0001] This utility model belongs to the technical field of digital calipers and wireless transmission components, specifically a quick docking device for digital calipers and wireless transmission components. Background Technology

[0002] In precision manufacturing, electronic processing, and mechanical quality inspection, digital calipers, as core measuring tools, are widely used for rapid measurement of workpiece dimensions due to their high precision and intuitive readings. However, with the advancement of intelligent manufacturing technology, the traditional reliance on manual data recording with digital calipers has gradually revealed problems such as low efficiency, error-proneness, and data lag, failing to meet the demands of real-time quality data collection, analysis, and traceability in modern production lines. Therefore, combining digital calipers with wireless transmission components to achieve automatic uploading and cloud management of measurement data has become a key direction for upgrading digital quality inspection.

[0003] Currently, docking devices for digital calipers and wireless transmission components are available on the market. Their core function is to connect the wireless transmission module to the data interface of the digital caliper via a mechanical structure, enabling wireless data transmission. Existing docking methods mainly include three types: plug-in docking, screw-fixed docking, and magnetic docking. Plug-in docking is simple in structure and convenient to operate, but lacks a precise positioning and guiding mechanism. During docking, misalignment between the plug and the digital caliper connector can easily occur, leading to poor contact. Especially under conditions of workshop vibration and frequent personnel operation, connection stability is poor, and data transmission interruptions are likely. Screw-fixed docking improves connection strength, but requires tools for installation and disassembly, making rapid docking impossible. Repeated disassembly and assembly can cause interface wear, affecting service life. Magnetic docking achieves rapid adsorption and docking through magnetic force, but its positioning accuracy depends on the magnet's adsorption position, making it prone to misalignment. Furthermore, the weakening of the magnetic force can lead to loosening of the connection, making it unsuitable for the high-frequency use requirements of industrial environments.

[0004] Therefore, this utility model provides a quick docking device for digital calipers and wireless transmission components. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a rapid docking device for digital calipers and wireless transmission components is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The quick docking device for a digital caliper and a wireless transmission component of this utility model includes a digital caliper; a connector is fixedly installed on one side of the digital caliper, a plug is movably inserted into the side of the connector away from the digital caliper, a wireless transmission component is fixedly installed on the side of the plug away from the connector, a positioning mechanism is provided on the side of the digital caliper close to the wireless transmission component, and auxiliary components are provided on both sides of the positioning mechanism away from the digital caliper; a plugging mechanism is provided on both sides of the wireless transmission component close to the digital caliper, and the connector is close to the wireless transmission component... A limit component is provided on one side of the plug; a clamping mechanism is provided on the side of the plug near the digital caliper, and a tightening component is provided on the side of the fixing block away from the digital caliper; the positioning mechanism includes a fixing block, a first shaft frame, and a positioning cylinder. The fixing block is fixedly installed on the side of the digital caliper near the connector, and both sides of the surface of the fixing block are fixedly installed with the first shaft frame. The side of the first shaft frame away from the digital caliper is fixedly installed with the positioning cylinder. The cooperation of the fixing block, the first shaft frame, and the positioning cylinder can achieve docking with the insertion mechanism, thereby achieving precise positioning to prevent the plug from tilting or jamming and ensure that the plug can be inserted vertically.

[0007] Preferably, the auxiliary component includes a first cone and a first magnetic ring. The first cone is fixedly installed on the side of the positioning cylinder away from the first shaft frame, and the first magnetic ring is fixedly installed on the side of the first cone away from the positioning cylinder. In this scheme, the cooperation between the first cone and the first magnetic ring can accurately guide the plug into the positioning cylinder when the plug is inserted, so that the positioning cylinder and the plug can be connected first, thereby ensuring the stability of the plug insertion.

[0008] Preferably, the insertion mechanism includes a second shaft, a plug rod, a spring, and a second magnetic ring. The second shaft is fixedly installed on both sides of the plug surface. The side of the second shaft closer to the digital caliper is fixedly installed with the plug rod. The side of the second shaft closer to the plug rod and located on the surface of the plug rod is fixedly installed with the spring. The side of the spring away from the second shaft is fixedly installed with the second magnetic ring. The second magnetic ring and the first magnetic ring attract each other. In this scheme, the cooperation of the second shaft and the plug rod allows the plug to preferentially insert with the positioning cylinder when it is connected to the connector, thereby providing a positioning function for the plug and enabling it to be accurately aligned with the connector, avoiding deviation. The cooperation of the spring and the second magnetic ring allows for auxiliary alignment through the magnetic attraction between the second and first magnetic rings when the plug rod is close to the first conical cylinder.

[0009] Preferably, the limiting component includes a fixed circular plate and grooves. The fixed circular plate is fixedly installed on the side of the connector near the plug. The grooves are provided in four sets, which are arranged in a ring on the surface of the fixed circular plate. In this design, after the fixed circular plate and the grooves are inserted, the elastic piece can be embedded in the groove, so that the elastic piece can no longer rotate the plug. It can also engage with the locking block, so that when the plug is strongly pulled out, it can be locked by the locking block and the fixed circular plate, making it difficult for the plug to be pulled out.

[0010] Preferably, the clamping mechanism includes an elastic plate, a circular block, and a locking block. Four sets of elastic plates are arranged in a ring and fixedly installed on the side of the plug near the connector. The side of the elastic plate away from the plug is fixedly installed with the circular block, and the bottom of the circular block is fixedly installed with the locking block. The elastic plate is in an inclined position. In this design, the coordinated use of the elastic plate, circular block, and locking block allows them to be inserted into the inner wall of the fixing ring during insertion, guided by the second cone. This allows them to fit tightly against the inner wall of the fixing ring through their own elasticity, and a stable connection is achieved through the friction between the elastic plate and the fixing ring.

[0011] Preferably, the tightening assembly includes a fixing ring and a second cone. The fixing ring is fixedly installed on the side of the fixing block away from the digital caliper. The side of the fixing ring away from the fixing block is fixedly installed with the second cone. The elastic plate and the circular block are movably inserted into the inner wall of the fixing ring through the second cone. In this scheme, the cooperation between the fixing ring and the second cone facilitates the insertion of the elastic plate, and the elasticity of the elastic plate enables the plug to be firmly inserted into the connector, thereby preventing loosening.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The quick docking device for digital calipers and wireless transmission components described in this utility model, through the arrangement of a fixing block, a first shaft frame, a positioning cylinder, a first conical cylinder, and a first magnetic ring, enables the fixing block, the first shaft frame, and the positioning cylinder to dock with the insertion mechanism, thereby achieving precise positioning to prevent the plug from tilting or jamming and ensuring that the plug can be inserted vertically. The cooperation between the first conical cylinder and the first magnetic ring can accurately guide the insertion rod into the positioning cylinder when the insertion rod is inserted, so that the positioning cylinder and the insertion rod dock first, thereby ensuring the stability of the plug insertion.

[0014] 2. The quick docking device for digital calipers and wireless transmission components described in this utility model, through the arrangement of a second shaft frame, a plug rod, a spring, a second magnetic ring, a fixed circular plate, and a groove, allows the second shaft frame and the plug rod to preferentially engage with the positioning cylinder when the plug and the connector are docked, providing positioning for the plug and ensuring accurate alignment with the connector to avoid deviation. The spring and the second magnetic ring work together to assist alignment when the plug rod approaches the first conical cylinder through the magnetic attraction between the second and first magnetic rings. After the insertion is completed, the fixed circular plate and the groove allow the elastic piece to be embedded in the groove, preventing the elastic piece from rotating and allowing it to engage with the locking block. This ensures that when the plug is forcefully pulled out, the locking block and the fixed circular plate can lock it in place, making it difficult to pull out. Attached Figure Description

The fastening mechanism 9 has a tightening component 10 on the side of the fixing block 51 away from the digital caliper 1; the positioning mechanism 5 includes a fixing block 51, a first shaft bracket 52, and a positioning cylinder 53. The fixing block 51 is fixedly installed on the side of the digital caliper 1 near the connector 3, and both sides of the surface of the fixing block 51 are fixedly installed with the first shaft bracket 52. The side of the first shaft bracket 52 away from the digital caliper 1 is fixedly installed with the positioning cylinder 53; the auxiliary component 6 includes a first cone cylinder 61 and a first magnetic ring 62. The first cone cylinder 61 is fixedly installed on the side of the positioning cylinder 53 away from the first shaft bracket 52, and the first magnetic ring 62 is fixedly installed on the side of the first cone cylinder 61 away from the positioning cylinder 53; the insertion mechanism 7 includes a second shaft bracket 71 and an insertion rod. 72, spring 73, and second magnetic ring 74; second shaft bracket 71 is fixedly installed on both sides of the surface of plug 4; the side of second shaft bracket 71 near digital caliper 1 is fixedly installed with plug rod 72; the side of second shaft bracket 71 near plug rod 72 and located on the surface of plug rod 72 is fixedly installed with spring 73; the side of spring 73 away from second shaft bracket 71 is fixedly installed with second magnetic ring 74; second magnetic ring 74 and first magnetic ring 62 attract each other; limiting assembly 8 includes fixed circular plate 81 and groove 82; fixed circular plate 81 is fixedly installed on the side of connector 3 near plug 4; four sets of grooves 82 are formed in a ring on the surface of fixed circular plate 81; clamping mechanism 9 includes... The assembly includes an elastic sheet 91, a circular block 92, and a locking block 93. The elastic sheet 91 is provided in four sets, and the four sets of elastic sheets 91 are fixedly installed in a ring on the side of the plug 4 near the connector 3. The side of the elastic sheet 91 away from the plug 4 is fixedly installed with the circular block 92. The bottom of the circular block 92 is fixedly installed with the locking block 93. The elastic sheet 91 is in an inclined position. The tightening assembly 10 includes a fixing ring 101 and a second cone 102. The fixing ring 101 is fixedly installed on the side of the fixing block 51 away from the digital caliper 1. The side of the fixing ring 101 away from the fixing block 51 is fixedly installed with the second cone 102. The elastic sheet 91 and the circular block 92 are movably inserted into the inner wall of the fixing ring 101 through the second cone 102.

[0027] like Figures 1 to 6As shown, the cooperation of the fixing block 51, the first shaft bracket 52, and the positioning cylinder 53 enables docking with the insertion mechanism 7, thereby achieving precise positioning to prevent the plug 4 from tilting or jamming and ensuring that the plug 4 can be inserted vertically. The cooperation of the first cone cylinder 61 and the first magnetic ring 62 allows the plug rod 72 to be precisely guided into the positioning cylinder 53 when it is inserted, thus allowing the positioning cylinder 53 to dock with the plug rod 72 first, ensuring the stability of the plug 4 insertion. The cooperation of the second shaft bracket 71 and the plug rod 72 allows the plug 4 to dock with the positioning cylinder 53 first when it is connected to the connector 3, providing positioning for the plug 4 and ensuring that it is accurately aligned with the connector 3, avoiding deviation. The cooperation of the spring 73 and the second magnetic ring 74 allows the second magnetic ring 74 to assist in alignment when the plug rod 72 approaches the first cone cylinder 61 through the magnetic attraction between the second magnetic ring 74 and the first magnetic ring 62. The fixed circular plate 81 and the groove 82 allow the elastic piece 91 to be embedded in the groove 82 after insertion, thus preventing the plug 4 from rotating. The elastic piece 91 can also engage with the locking block 93, ensuring that the plug 4 is securely locked when forcefully pulled out, preventing it from being pulled out easily. The combined use of the elastic piece 91, the circular block 92, and the locking block 93 allows the plug 4 to be inserted into the inner wall of the fixing ring 101 through the guidance of the second cone 102 during insertion. Its own elasticity allows it to fit tightly against the inner wall of the fixing ring 101, and the friction between the elastic piece 91 and the fixing ring 101 achieves a stable connection. The combination of the fixing ring 101 and the second cone 102 facilitates the insertion of the elastic piece 91, and the elasticity of the elastic piece 91 ensures that the plug 4 is firmly inserted into the connector 3, preventing loosening.

[0028] Working principle: During operation, first keep the digital caliper 1 vertical. Then, the user picks up the wireless transmission component 2 and aligns the plug 4 with the connector 3. At that time, the second magnetic ring 74 will attract the first magnetic ring 62, providing guidance for the insertion rod 72. Then, the plug 4 is inserted into the inner wall of the connector 3. During insertion, the insertion rod 72 will be inserted into the first cone 61. Then, through the conical guide of the first cone 61, the insertion rod 72 is steadily guided into the positioning cylinder 53. When the insertion rod 72 is inserted into the positioning cylinder 53, the second magnetic ring 74 will compress the spring 73 until the plug 4 is inserted in place. At the same time, when the plug 4 is inserted, the circular block 92 will be affected by the second cone 102. The tapered guide is compressed until the elastic piece 91 remains vertical. Then, the elastic piece 91 is inserted into the fixing ring 101 and embedded in the groove 82, thus completing the docking. In use, if the wireless transmission component 2 is pulled out quickly, the elastic piece 91 will not be able to reset due to the excessive speed, so that the locking block 93 can hook onto the fixing circular plate 81, making it impossible to disassemble the wireless transmission component 2. When disassembly is required, the user only needs to slowly pull out the wireless transmission component 2. When the locking block 93 moves into the second cone 102, the elasticity of the elastic piece 91 will drive it to reset and maintain an inclined posture. At that time, the locking block 93 can be pulled out.
