Description

Technical Field

[0001] This utility model relates to the field of positioning rib measurement technology, and in particular to an adjustable dial gauge distance measuring device. Background Technology

[0002] For example, publication number "CN218723764U" discloses "a measuring tool for measuring the chord distance of the ribs in a dovetail-shaped positioning rib section," which includes a measuring rod, a sliding rod, and a dial indicator. The dial indicator's probe is used to press against the measuring point on the second positioning rib, and the first and second positioning ribs are arranged adjacent to each other. The centerline of the dial indicator's probe along its length is collinear with the centerline of the measuring rod along its length. However, in practical applications, the end of this type of measuring tool with the dial indicator cannot maintain stability during measurement, making it inconvenient for operators. Adding a handle for stability would affect the telescopic function. Summary of the Invention

[0003] In view of the problem mentioned in the background art that the existing technology cannot be equipped with a handle for assistance, which affects the telescopic function, this utility model provides an adjustable dial gauge distance measuring device. It can provide a handle to assist the operator in measuring while ensuring the telescopic function, so as to avoid the handle interfering with the telescopic process and improve the flexibility and stability of the device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] An adjustable dial indicator distance measuring device includes several telescopic rods that are connected together. Each telescopic rod includes an end measuring rod, on which a dial indicator is connected. A handle is rotatably connected to the end measuring rod. Each telescopic rod also includes an end fixing rod, on which a measuring connector is provided. A locking plate is rotatably connected to the handle. The locking plate can engage with the end measuring rod. A locking hole is provided at the end of the locking plate, and a through hole is provided on the measuring connector. When each telescopic rod is retracted, the locking plate can rotate relative to the handle until the locking hole aligns with the through hole.

[0006] In this application, the telescopic rods at both ends of the entire device are an end measuring rod and an end fixing rod, respectively. The end measuring rod is connected to a dial indicator, which contacts the object being measured for measurement. The end fixing rod is connected to a measuring connector, which abuts against the object being measured at the other end to achieve a positioning effect, thereby completing the measurement of the positioning rib. Since the telescopic rods are connected by a sleeve, each telescopic rod can extend and retract relative to the others, thereby achieving overall length control. Since the dial indicator is located on the end measuring rod, the handle is also located on the end measuring rod, which makes it convenient for the operator to hold and assists the operator in controlling the stability of the entire device, and also improves the control accuracy of the dial indicator. In this application, a locking plate is rotatably connected to the handle, while the other end of the handle can rotate relative to the end measuring rod. In the actual measurement process, it is necessary to extend the end measuring rod and control the dial indicator to measure data. Therefore, the handle and end measuring rod can rotate relative to each other, allowing the locking plate to engage with the end measuring rod. This fixes the handle relative to the end measuring rod, facilitating operation. When the measurement is completed and the telescopic rod needs to be retracted, the locking plate is disengaged from the end measuring rod, causing the handle to rotate relative to the end measuring rod. The handle is rotatably connected to the end measuring rod at the end of the end measuring rod away from the end fixing rod. This allows the handle to retract to the maximum extent into the next telescopic rod after disengaging the locking plate and rotating, reducing the overall retraction size and preventing the handle from interfering with the retraction of the telescopic rod. Meanwhile, a through hole is provided on the measuring connector. When the telescopic rod is retracted, the relative rotation of the handle and the relative rotation of the locking plate can align the locking hole on the locking plate with the through hole. Then, the locking hole and the through hole are locked together by bolts or pins, thus ensuring the connection between the handle and the measuring connector. This prevents the telescopic rod from coming off by itself due to loosening. The combination of the locking hole and the through hole ensures the mutual limiting constraint between the handle and the telescopic rod, thereby ensuring the stability of the device in the retracted state and preventing damage caused by the handle rotating arbitrarily or the telescopic rod extending or retracting.

[0007] Preferably, the ends of adjacent telescopic rods are provided with threaded pairs that can be threaded together. The threaded pairs at the ends of the telescopic rods ensure the stability of the connection between them, and tighten adjacent telescopic rods together to prevent expansion and contraction during testing.

[0008] Preferably, the end measuring rod is provided with an extension plate, and the handle is rotatably connected to the extension plate. There is a clearance between the connection between the extension plate and the handle and the end measuring rod. By providing an extension plate on the end measuring rod and leaving a clearance between the handle and the end measuring rod, the handle will not interfere with or abut against other telescopic rods with larger diameters during the extension and retraction of the telescopic rod, thus improving the smoothness of use.

[0009] Preferably, a positioning bolt is provided between the extension plate and the handle, and the handle can rotate around the positioning bolt. The positioning bolt between the extension plate and the handle allows the handle to rotate relative to the extension plate. At the same time, by tightening the positioning bolt, the connection tightness between the handle and the extension plate can be changed, thereby fixing the rotational position of the handle and ensuring the stability of the handle. The positioning bolt is a combination of a bolt and a nut threaded pair.

[0010] Preferably, the extension plate and the end measuring rod are fixedly connected. By setting a fixed connection between the extension plate and the end measuring rod, the connection stability between the extension plate and the end measuring rod can be enhanced. The fixed connection includes, but is not limited to, welding, integral molding, etc.

[0011] Preferably, the locking plates are provided on both sides of the handle. Each locking plate has a semi-circular groove with opposing openings, which engages with the end measuring rod. An adjusting bolt for connecting the handle is provided on each locking plate, and a locking bolt is provided on the side of the semi-circular groove away from the adjusting bolt. Two locking plates are provided, one on each side of the handle. Since there are locking plates on both sides, the semi-circular grooves can combine to form a structure that engages with the end measuring rod. The adjusting bolt connects the locking plate to the handle, and its tightness affects whether the locking plate can rotate relative to the handle, thus adjusting the relative position of the locking plates. The locking bolt secures the two locking plates, ensuring a stable connection and preventing them from disengaging from the end measuring rod due to their elasticity.

[0012] Preferably, the diameter of the through hole is greater than or equal to the diameter of the locking bolt. This through hole diameter allows the locking bolt to pass through the locking plate connection hole. When the telescopic rod is retracted, the locking plate can unlock and disengage from the end measuring rod, rotating it to a position aligned with the through hole. This allows the locking plate to connect with the measuring connector. The locking plate connection ensures connection stability, fixes the telescopic rod to prevent it from disengaging, and also fixes the handle to prevent it from swinging, ensuring the device's retraction stability and safety.

[0013] Preferably, the locking plate includes a rotating plate with a rotatable connecting handle, and a fixed plate that can connect to the end measuring rod. A pivot is provided between the fixed plate and the rotating plate, allowing the rotating plate to rotate relative to the fixed plate. The locking plate has a rotating plate and a fixed plate that can rotate relative to each other. The fixed plate is connected to the end measuring rod, while the rotating plate can rotate relative to the fixed plate. This allows the semi-circular groove to more easily engage with the end measuring rod during the connection process, facilitating subsequent disengagement. Furthermore, during the connection of the end measuring rod or measuring connector, the locking bolts provide stability, ensuring both stability and flexibility.

[0014] Preferably, a mounting plate is provided on the end measuring rod away from the end fixing rod, and a dial indicator is rotatably connected to the mounting plate. The dial indicator's rotatable connection to the mounting plate ensures its flexibility.

[0015] Preferably, the measuring connector is provided with a locking groove that adapts to the contour of the product being measured. By adapting the measuring connector to the contour of the product, the connection stability between the measuring connector and the product is ensured.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) While ensuring the telescopic function, a handle can be set up to assist the staff in taking measurements, so as to avoid the handle interfering with the telescopic process and improve the flexibility and stability of the device.

[0018] (2) It can ensure the stability of the telescopic rod of the handle, avoid the telescopic rod from extending and the handle from swinging when it is retracted, and ensure safety. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] like Figure 1 , 2 As shown in Figure 3, an adjustable dial indicator distance measuring device includes several telescopic rods 1 connected together. Each telescopic rod 1 includes an end measuring rod 11, a dial indicator 2 connected to the end measuring rod 11, and a handle 3 rotatably connected to the end measuring rod 11. Each telescopic rod 1 includes an end fixing rod 12, a measuring connector 4 provided on the end fixing rod 12, and a locking piece 31 rotatably connected to the handle 3. The locking piece 31 can engage with the end measuring rod 11. A locking hole 311 is provided at the end of the locking piece 31, and a through hole 41 is provided on the measuring connector 4. When each telescopic rod 1 is retracted, the locking piece 31 can rotate relative to the handle 3 until the locking hole 311 is aligned with the through hole 41.

[0031] In this application, the telescopic rods 1 at both ends of the entire device are an end measuring rod 11 and an end fixing rod 12, respectively. The end measuring rod 11 is connected to a dial indicator 2, which contacts the object being measured for measurement. The end fixing rod 12 is connected to a measuring connector 4, which abuts against the object being measured at the other end to achieve a positioning effect, thereby completing the measurement of the positioning rib. Since the telescopic rods 1 are connected by a sleeve, each telescopic rod 1 can extend and retract relative to the others, thereby achieving overall length control. Since the dial indicator 2 is set on the end measuring rod 11, the handle 3 is also set on the end measuring rod 11, which makes it convenient for the operator to hold and assists the operator in controlling the stability of the entire device, and also improves the control accuracy of the dial indicator 2. In this application, a locking plate 31 is rotatably connected to the handle 3, and the other end of the handle 3 can rotate relative to the end measuring rod 11. In the actual measurement process, it is necessary to extend the end measuring rod 11 and control the dial indicator 2 to measure data. Therefore, the handle 3 can rotate relative to the end measuring rod 11, so that the locking plate 31 can be engaged with the end measuring rod 11. This fixes the handle 3 relative to the end measuring rod 11, making it convenient for the operator to use. When the measurement is finished and the telescopic rod 1 needs to be retracted, the locking plate 31 is disengaged from the end measuring rod 11, and the handle 3 rotates relative to the end measuring rod 11. The position where the handle 3 is rotatably connected to the end measuring rod 11 is the end of the end measuring rod 11 away from the end fixing rod 12. This allows the handle 3 to disengage from the connection between the locking plate 31 and the end measuring rod 11 and rotate, so that the end measuring rod 11 can retract to the maximum extent into the next telescopic rod 1, thereby reducing the overall retraction size and avoiding the handle 3 interfering with the retraction of the telescopic rod 1. Meanwhile, a through hole 41 is also provided on the measuring connector 4. When the telescopic rod 1 is retracted, the relative rotation of the handle 3 and the relative rotation of the locking plate 31 can align the locking hole 311 on the locking plate 31 with the through hole 41. Then, the locking hole 311 and the through hole 41 are locked together by bolts or pins, thereby ensuring the connection between the handle 3 and the measuring connector 4. This prevents the telescopic rod 1 from coming off by itself due to loosening. The combination of the locking hole 311 and the through hole 41 ensures the mutual limiting constraint between the handle 3 and the telescopic rod 1, thereby ensuring the stability of the device in the retracted state and preventing damage caused by the arbitrary rotation of the handle 3 or the extension and retraction of the telescopic rod 1.

[0032] The ends of adjacent telescopic rods 1 are provided with threaded pairs that can be threaded together. The threaded pairs at the ends of the telescopic rods 1 ensure the connection stability between the telescopic rods 1, and the adjacent telescopic rods 1 are tightened together by the threaded pairs to prevent expansion and contraction during the testing process.

[0033] like Figure 2 As shown, an extension plate 32 is provided on the end measuring rod 11, and the handle 3 is rotatably connected to the extension plate 32. There is a clearance distance 33 between the connection between the extension plate 32 and the handle 3 and the end measuring rod 11. By providing the extension plate 32 on the end measuring rod 11 and leaving a clearance distance 33 between the handle 3 and the end measuring rod 11, the handle 3 will not interfere with or abut against other telescopic rods 1 with larger diameters during the extension and retraction of the telescopic rod 1, thus improving the smoothness of use.

[0034] like Figure 2 As shown, a positioning bolt 34 is provided between the extension plate 32 and the handle 3, allowing the handle 3 to rotate around the positioning bolt 34. The positioning bolt 34 between the extension plate 32 and the handle 3 allows the handle 3 to rotate relative to the extension plate 32. Simultaneously, by tightening the positioning bolt 34, the connection tightness between the handle 3 and the extension plate 32 changes, thereby fixing the rotational position of the handle 3 and ensuring its stability. The positioning bolt 34 is a combination of a bolt and a nut threaded pair.

[0035] like Figure 2 As shown, the extension plate 32 and the end measuring rod 11 are fixedly connected. By setting a fixed connection between the extension plate 32 and the end measuring rod 11, the connection stability between the extension plate 32 and the end measuring rod 11 can be enhanced. The fixed connection includes, but is not limited to, welding, integral molding, etc.

[0036] like Figure 2 , 3 As shown, locking plates 31 are provided on both sides of the handle 3. The locking plates 31 on both sides are provided with semi-circular grooves 312 with opposite openings. The semi-circular grooves 312 can engage with the end measuring rod 11. The locking plates 31 are provided with adjusting bolts 35 for connecting the handle 3. The locking plates 31 are provided with locking bolts 36 on the side of the semi-circular grooves 312 away from the adjusting bolts 35. Two locking plates 31 are provided, one on each side of the handle 3. Each locking plate 31 has a semi-circular groove 312. Since there are locking plates 31 on both sides, the semi-circular grooves 312 can be combined to form a structure that engages with the end measuring rod 11. An adjusting bolt 35 and a locking bolt 36 are provided on the locking plates 31. The adjusting bolt 35 connects the locking plate 31 and the handle 3, and the tightness of the adjusting bolt 35 can affect whether the locking plate 31 can rotate relative to the handle 3, thereby adjusting the relative position of the locking plate 31. The locking bolt 36 is also provided on the locking plate 31. The locking bolt 36 can lock the two locking plates 31, so that the semi-circular grooves 312 on the two locking plates 31 can be locked and engaged with the end measuring rod 11, ensuring the stability of the connection and preventing the locking plates 31 from coming off the end measuring rod 11 due to their elasticity.

[0037] The diameter of the through hole 41 is greater than or equal to the diameter of the locking bolt 36. This allows the locking bolt 36 to pass through the locking plate 31 and connect to the through hole 41. When the telescopic rod 1 is retracted, the locking plate 31 can be unlocked and disengaged from the end measuring rod 11, rotating to a position aligned with the through hole 41. This allows the locking plate 31 to connect with the measuring connector 4. The connection through the locking plate 31 ensures the stability of the connection, fixing the telescopic rod 1 and preventing it from disengaging. Simultaneously, it fixes the handle 3, preventing it from swinging, thus ensuring the stability and safety of the device's retraction.

[0038] like Figure 2 As shown, a mounting plate 111 is provided on the end measuring rod 11 away from the end fixing rod 12, and a dial indicator 2 is rotatably connected to the mounting plate 111. By rotatably connecting the dial indicator 2 to the mounting plate 111, the flexibility of the dial indicator 2 can be ensured.

[0039] like Figure 1 As shown, the measuring connector 4 is provided with a locking groove 42 that adapts to the contour of the product being measured. By adapting the measuring connector 4 to the contour of the product, the connection stability between the measuring connector 4 and the product is ensured.

[0040] Example 2:

[0041] like Figure 4 As shown, in this embodiment, the locking plate 31 includes a rotating plate 313 that rotatably connects to the handle 3, and a fixing plate 314 that connects to the end measuring rod 11. A rotating shaft 315 is provided between the fixing plate 314 and the rotating plate 313, allowing the rotating plate 313 to rotate relative to the fixing plate 314. The locking plate 31 is provided with a rotating plate 313 and a fixing plate 314 that can rotate relative to each other. The fixing plate 314 is connected to the end measuring rod 11, while the rotating plate 313 can rotate relative to the fixing plate 314. This allows the semi-annular groove 312 to more easily engage with the end measuring rod 11 during the process of connecting the locking plate 31 to the end measuring rod 11, and also facilitates subsequent disengagement. At the same time, during the process of connecting the end measuring rod 11 or the measuring connector 4, the locking bolt 36 can be used for stabilization, ensuring stability and flexibility.

[0042] This embodiment also includes several telescopic rods 1 connected together. Each telescopic rod 1 includes an end measuring rod 11, a dial indicator 2 connected to the end measuring rod 11, and a handle 3 rotatably connected to the end measuring rod 11. Each telescopic rod 1 also includes an end fixing rod 12, on which a measuring connector 4 is provided. A locking plate 31 is rotatably connected to the handle 3, and the locking plate 31 can engage with the end measuring rod 11. A locking hole 311 is provided at the end of the locking plate 31, and a through hole 41 is provided on the measuring connector 4. When each telescopic rod 1 retracts, the locking plate 31 can rotate relative to the handle 3 until the locking hole 311 aligns with the through hole 41. Adjacent telescopic rods 1 have threaded pairs at their ends that can be threaded together. An extension plate 32 is provided on the end measuring rod 11, and the handle 3 is rotatably connected to the extension plate 32. A clearance distance 33 exists between the connection between the extension plate 32 and the handle 3 and the end measuring rod 11. A positioning bolt 34 is provided between the extension plate 32 and the handle 3, and the handle 3 can rotate around the positioning bolt 34. The extension plate 32 is fixedly connected to the end measuring rod 11. Locking plates 31 are provided on both sides of the handle 3, and each locking plate 31 has a semi-circular groove 312 with opposing openings. The semi-circular groove 312 can engage with the end measuring rod 11. An adjusting bolt 35 for connecting the handle 3 is provided on the locking plate 31, and a locking bolt 36 is provided on the side of the locking plate 31 away from the adjusting bolt 35. The diameter of the through hole 41 is greater than or equal to the diameter of the locking bolt 36. A mounting plate 111 is provided on the end measuring rod 11 away from the end fixing rod 12, and a dial indicator 2 is rotatably connected to the mounting plate 111. The measuring connector 4 has a locking groove 42 adapted to the contour of the measured product.

[0043] A threaded pair is provided at the end of the telescopic rod 1. This threaded pair ensures the connection stability between the telescopic rods 1 and secures adjacent telescopic rods 1 tightly, preventing extension and contraction during testing. An extension plate 32 is provided on the end measuring rod 11. The extension plate 32 provides a clearance distance 33 between the handle 3 and the end measuring rod 11, ensuring that the handle 3 does not interfere with or abut against other telescopic rods 1 with larger diameters during the extension and contraction of the telescopic rod 1, improving the smoothness of use. A positioning bolt 34 is provided between the extension plate 32 and the handle 3. The positioning bolt 34 allows the handle 3 to rotate relative to the extension plate 32. Tightening the positioning bolt 34 changes the connection tightness between the handle 3 and the extension plate 32, thus fixing the rotational position of the handle 3 and ensuring its stability. The positioning bolt 34 is a combination of a bolt and a nut threaded pair. By establishing a fixed connection between the extension plate 32 and the end measuring rod 11, the connection stability between them is enhanced. This fixed connection includes, but is not limited to, welding and integral molding. Two locking plates 31 are provided, one on each side of the handle 3. Each locking plate 31 has a semi-circular groove 312. Since there are locking plates 31 on both sides, the semi-circular grooves 312 can be combined to form a structure that engages with the end measuring rod 11. An adjusting bolt 35 and a locking bolt 36 are provided on the locking plates 31. The adjusting bolt 35 connects the locking plate 31 and the handle 3, and the tightness of the adjusting bolt 35 can affect whether the locking plate 31 can rotate relative to the handle 3, thereby adjusting the relative position of the locking plate 31. The locking bolt 36 is also provided on the locking plate 31. The locking bolt 36 can lock the two locking plates 31, so that the semi-circular grooves 312 on the two locking plates 31 can be locked and engaged with the end measuring rod 11, ensuring the stability of the connection and preventing the locking plates 31 from coming off the end measuring rod 11 due to their elasticity.

[0044] 7. The diameter of the through hole 41 is greater than or equal to the diameter of the locking bolt 36, allowing the locking bolt 36 to pass through the locking plate 31 and connect to the through hole 41. When the telescopic rod 1 is retracted, the locking plate 31 can be unlocked and disengaged from the end measuring rod 11, rotating to a position aligned with the through hole 41. This allows the locking plate 31 to connect with the measuring connector 4. The connection of the locking plate 31 ensures the stability of the connection, fixes the telescopic rod 1 to prevent it from disengaging, and fixes the handle 3 to prevent it from swinging, ensuring the stability and safety of the device's retraction. The dial indicator 2 is rotatably connected to the mounting plate 111, ensuring the flexibility of the dial indicator 2. The measuring connector 4 is adapted to the contour of the product, ensuring the stability of the connection between the measuring connector 4 and the product.
