Description

Technical Field

[0001] This utility model relates to the field of lifting devices, specifically to an anti-slip lifting device for a flash meter. Background Technology

[0002] As a precision measuring instrument employing novel image measurement technology, the flash measurement instrument is widely used in various industries within the industrial manufacturing sector, including but not limited to machining, motor manufacturing, automotive parts production, precision hardware and tool manufacturing, mold design, and optical component processing. Its main feature is its ability to quickly and accurately measure two-dimensional planar dimensions. Even when equipped with an optical non-contact measuring head, it can achieve precise and rapid measurement of parameters such as height and flatness, improving production line efficiency and product quality.

[0003] In the use of a flash measuring instrument, the lifting device plays a crucial role. Existing flash measuring instruments are typically equipped with a lifting mechanism to adjust the height of the worktable or measuring head to accommodate the measurement needs of workpieces of different sizes and types. These lifting devices mostly employ mechanical structures, such as screw lifts, hydraulic lifts, or pneumatic lifts, and are adjusted manually or electrically. Their basic structure includes a base, support column, lifting mechanism, connecting parts, and worktable, which work together to ensure the smoothness and accuracy of the lifting process.

[0004] Chinese patent CN 115061272 B discloses a mechanical structure for a fully automatic continuous zoom stereomicroscope. The patent discloses a lifting mechanism including a fixed base, a gear, and a rack. The fixed base is fixed to a base 1, and a bushing is fixed through the fixed base, with both ends of the bushing extending to the outside of the fixed base. A rotating shaft is rotatably connected inside the bushing, with both ends of the rotating shaft extending to the outside of the bushing. The gear is fixed in the middle of the rotating shaft. A groove is provided on the fixed base, and the rack is slidably installed in the groove. A locking screw is threaded onto the bushing, with the end of the locking screw pressing against the rotating shaft. Knobs are provided at both ends of the rotating shaft for easy rotation. This patent discloses precise control and adjustment of the lifting structure.

[0005] However, while existing lifting devices meet the needs of measurement work to a certain extent, some obvious shortcomings still exist. Some lifting devices lack sufficient stability during lifting, especially when carrying heavy workpieces, and are prone to swaying or tilting, affecting the accuracy of measurements. Furthermore, existing lifting devices rely solely on locking screws for locking, which also lacks anti-slip performance when carrying heavy workpieces. When the slide is subjected to external forces in the vertical direction, it is prone to sliding or displacement due to its own weight or vibration if operated carelessly or the workpiece is improperly placed, thus affecting the accuracy of the testing instrument and the stability of the testing process. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned defects and provide an anti-slip lifting device for a flash meter, so as to solve the technical problem that the existing slide table is prone to sliding due to its own weight or the influence of the load in the above-mentioned background art, and the existing locking structure is relatively simple, which leads to the sliding of the slide table affecting the measurement accuracy and stability of the testing instrument.

[0007] The objective of this utility model is achieved through the following means:

[0008] The anti-slip lifting device for the flash meter includes a base, a mounting seat on the base, and a slide table slidably connected to the mounting seat. The base has two connecting plates for connecting the mounting seat, and the mounting seat is installed between the two connecting plates. The mounting seat and the slide table are paired and connected by a guide rail. The mounting seat has an adjustment mechanism for adjusting the slide table to slide up and down along the guide rail. The adjustment mechanism is connected to a locking member for locking and limiting the slide table. The side of the connecting plate has an anti-slip plate for anti-slip limiting. The side of the slide table near the connecting plate has a limiting part that is opposite to the anti-slip plate. A limiting screw is connected to the limiting part by a screw sleeve. One end of the limiting screw can pass through the limiting part and press against the side of the anti-slip plate, so that one end of the limiting screw makes frictional contact with the anti-slip plate.

[0009] Furthermore, as described above, the mounting base has a through groove, a guide rail is mounted on the groove, and a slide table is mounted on the guide rail and can slide along the guide rail in the direction of extension of the groove. The guide rail is made of a V-shaped guide rail. The mounting base and the slide table are connected by the V-shaped guide rail, which improves the adjustment accuracy and stability of the slide table.

[0010] Further, as described above, the adjustment mechanism includes a gear, a rack meshing with the gear, a sleeve, a connecting rod, and an adjustment handwheel. A mounting groove is provided on the mounting base, the gear is disposed within the mounting groove, and the end of the gear extends to both sides of the mounting base to form a connecting portion. One end of the sleeve extends into the mounting groove and is coaxially connected to the connecting portion. One end of the connecting rod passes through the sleeve and is connected to the connecting portion, and the other end of the connecting rod is connected to the adjustment handwheel. The rack is mounted on the back of the slide and meshes with the gear, so that the rotation of the adjustment handwheel can drive the slide to move up and down via the gear.

[0011] The meshing of gears and racks allows the rotation of the gears to drive the rack to slide. The design of the slide groove and guide rail allows the rack to drive the slide table to move up and down along the guide rail, further improving the precise control and adjustment of the slide table and enhancing the stability and reliability of the adjustment.

[0012] Furthermore, as described above, both ends of the gear are provided with connecting parts, and two sets of sleeves, connecting rods and adjusting handwheels are provided. The sleeves, connecting rods and adjusting handwheels are symmetrically arranged on both sides of the mounting base and paired with the connecting parts of the gear.

[0013] The two sets of sleeves, connecting rods, and adjusting handwheels make it easy to use and adjust.

[0014] Furthermore, as described above, the end of the sleeve away from the mounting base is formed with a locking part that can be opened and closed radially. The locking member is connected to the locking part by a thread, so that the locking member can tension and lock the connecting rod inside the sleeve by closing the locking part.

[0015] The locking element connected by threads allows the locking part to close radially, thereby tensioning the connecting rod inside the sleeve. This prevents the adjusting handwheel from rotating the connecting rod, further enhancing the stability and precise control of the adjustment.

[0016] Furthermore, as described above, the anti-slip plate has an anti-slip groove on its side, one end of the limiting screw passes through the limiting part and presses against the anti-slip groove to limit it, and a retaining spring is connected to the end of the limiting screw near the anti-slip plate.

[0017] By pressing the end of the limiting screw against the anti-slip plate, anti-slip friction is formed on the contact surface, further enhancing the anti-slip displacement effect of the slide table, improving its stability and reliability, and thus improving the measurement accuracy and precision of the testing instrument.

[0018] Furthermore, as described above, the slide table has limiting portions on both sides, and two limiting screws are provided, with the two limiting screws symmetrically installed on the limiting portions.

[0019] The two limit screws can simultaneously press the slide table against the anti-slip plate on the side of the connecting plate, further enhancing the anti-slip effect of the anti-slip plate and preventing the slide table from shifting downwards due to its own weight. At the same time, it also ensures a stable connection between the base and the slide table when the locking device is locked, and enhances the high precision between the base and the slide table.

[0020] The beneficial effects of this utility model are as follows: The sliding connection between the slide table and the mounting base allows the slide table to move flexibly up and down along the guide rail. The adjustment mechanism on the mounting base allows users to easily control the up and down movement of the slide table, achieving precise adjustment of the slide table height, improving measurement accuracy and work efficiency. The locking component can lock and limit the slide table's lifting position, preventing accidental slippage during measurement and ensuring measurement stability and safety. The limit screw is connected to the limit part through a screw sleeve, and one end of the limit screw can pass through the limit part and press against the side of the anti-slip plate. The design of the limit screw and the anti-slip plate increases the friction when the slide table is locked, effectively preventing the slide table from slipping due to external forces during lifting and lowering, improving the anti-slip performance of the entire device, further enhancing the locking and limiting effect of the slide table's lifting position, and improving the stability and safety of the entire device. At the same time, the design of the limit screw facilitates manual adjustment and locking by the user, enhancing ease of use. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] In this embodiment, refer to Figures 1-7 The anti-slip lifting device for the flash detector includes a base 1, a mounting seat 2 on the base 1, and a slide 3 slidably connected to the mounting seat 2. The base 1 is provided with two connecting plates 4 for connecting the mounting seat 2. The mounting seat 2 is installed between the two connecting plates 4. The mounting seat 2 and the slide 3 are paired and connected by a guide rail 5. The mounting seat 2 is provided with an adjustment mechanism 6 for adjusting the slide 3 to slide up and down along the guide rail 5. The adjustment mechanism 6 is connected with a locking member 7 for locking and limiting the slide 3. The side of the connecting plate 4 is provided with an anti-slip plate 8 for anti-slip limiting. The side of the slide 3 near the connecting plate 4 has a limiting part 9 that is distributed opposite to the anti-slip plate 8. The limiting part 9 is connected to a limiting screw 11 through a screw sleeve 10. One end of the limiting screw 11 can pass through the limiting part 9 and press against the side of the anti-slip plate 8, so that one end of the limiting screw 11 makes frictional contact with the anti-slip plate 8.

[0031] Reference Figure 2 and Figure 3 The mounting base 2 has a through groove 12, a guide rail 5 is mounted on the groove 12, and a slide table 3 is mounted on the guide rail 5 and can slide along the guide rail 5 in the direction of extension of the groove 12. The guide rail 5 is made of V-shaped guide rail. The connection between the mounting base 2 and the slide table 3 through the V-shaped guide rail 5 improves the adjustment accuracy and stability of the slide table 3. The mating connection of the guide rail 5 ensures that the slide table 3 can slide smoothly and accurately along the mounting base 2, improving the efficiency and accuracy of lifting.

[0032] Reference Figure 6 and Figure 7 The adjustment mechanism 6 includes a gear 601, a rack 602 meshing with the gear 601, a sleeve 603, a connecting rod 604, and an adjusting handwheel 605. A mounting groove 13 is provided on the mounting base 2. The gear 601 is disposed within the mounting groove 13, and its end extends to both sides of the mounting base 2 to form a connecting portion 606. One end of the sleeve 603 extends into the mounting groove 13 and is coaxially connected to the connecting portion 606. One end of the connecting rod 604 passes through the sleeve 603 and is connected to the connecting portion 606, while the other end of the connecting rod 604 is connected to the adjusting handwheel 605. The rack 602 is mounted on the back of the slide table 3 and meshes with the gear 601, so that the rotation of the adjusting handwheel 605 can drive the slide table 3 to move up and down via the gear 601. Both ends of the gear 601 are provided with connecting parts 606. There are two sets of sleeves 603, connecting rods 604 and adjusting handwheels 605. The sleeves 603, connecting rods 604 and adjusting handwheels 605 are symmetrically arranged on both sides of the mounting base 2 and are paired and connected with the connecting parts 606 of the gear 601.

[0033] The meshing of gear 601 and rack 602 allows the rotation of gear 601 to drive the rack 602 to slide. The sliding groove 12 and guide rail 5 allow the rack 602 to drive the slide table 3 to slide up and down along the guide rail 5, further improving the precise control and adjustment of the slide table 3 and enhancing the stability and reliability of the adjustment. The two sets of sleeves 603, connecting rods 604, and adjusting handwheels 605 facilitate convenient use and adjustment.

[0034] Reference Figure 6 The end of the sleeve 603 away from the mounting base 2 has a locking part 607 that can open and close radially. The locking member 7 is threadedly connected to the locking part 607, so that the locking member 7 can tension and lock the connecting rod 604 inside the sleeve 603 by closing the locking part 607. The threaded locking member 7 can cause the locking part 607 to close radially, thereby tensioning the connecting rod 604 inside the sleeve 603, thus preventing the adjusting handwheel 605 from driving the connecting rod 604 to rotate, further enhancing the stability and precise control of the adjustment.

[0035] The anti-slip plate 8 has an anti-slip groove 14 on its side. One end of the limiting screw 11 passes through the limiting part 9 and presses against the anti-slip groove 14 to limit its movement. A retaining spring 15 is connected to the end of the limiting screw 11 near the anti-slip plate 8. By pressing against the anti-slip plate 8, the end of the limiting screw 11 forms anti-slip friction on the contact surface, further enhancing the anti-slip displacement effect of the slide table 3, improving its stability and reliability, and thus improving the measurement accuracy and precision of the testing instrument.

[0036] The limiting part 9 is positioned opposite to the anti-slip plate 8, providing an installation position for the limiting screw 11. This ensures that the limiting screw 11 can accurately press against the side of the anti-slip plate 8, thereby further locking and limiting the lifting position of the slide table 3.

[0037] Both sides of the slide table 3 have limiting portions 9, and two limiting screws 11 are provided, which are symmetrically installed on the limiting portions 9. The two limiting screws 11 can simultaneously press the slide table 3 against the anti-slip plate 8 on the side of the connecting plate 4, further enhancing the anti-slip effect of the anti-slip plate 8, preventing the slide table 3 from shifting downwards due to its own weight, and also ensuring a stable connection between the base 1 and the slide table 3 when the locking member 7 is locked, as well as enhancing the high precision between the base 1 and the slide table 3.

[0038] In this embodiment, the specific installation and use are as follows: two connecting plates 4 are symmetrically installed on both sides of the mounting base 2 and connected to the base 1. The slide table 3 and the mounting base 2 are slidably connected by a V-shaped guide rail 5, allowing the slide table 3 to move flexibly up and down along the guide rail 5. By adjusting the rotation of the handwheel 605, the connecting rod 604 can drive the gear 601 to rotate through the connecting part 606. The design of the handwheel 605 allows the user to easily control the up and down movement of the slide table 3, achieving precise adjustment of the height of the slide table 3, improving the accuracy of measurement and work efficiency. Through the threaded connection between the locking part 7 and the locking part 607, the closing of the locking part 607 clamps the connecting rod 604, thereby achieving the control of the slide table 3. The locking limit of the lifting position prevents the slide table 3 from sliding unexpectedly during the measurement process, ensuring the stability and safety of the measurement. The limiting screw 11 is connected to the limiting part 9 through the screw sleeve 10, and one end of the limiting screw 11 can pass through the limiting part 9 and press against the anti-slip groove 14 of the anti-slip plate 8. The design of the limiting screw 11 and the anti-slip plate 8 increases the friction when the slide table 3 is locked, effectively preventing the slide table 3 from slipping due to external force during the lifting process, improving the anti-slip performance of the entire device, further enhancing the locking limit effect of the lifting position of the slide table 3, and improving the stability and safety of the entire device. At the same time, the design of the limiting screw 11 makes it easy for users to manually adjust and lock, enhancing the convenience of use.
