Description
Technical Field
[0001] This utility model relates to the field of glass bottle measurement, and in particular to a depth measuring tool for glass bottles. Background Technology
[0002] In the production and quality inspection of glass bottles, accurately measuring the internal depth of the glass bottle is a key step in verifying capacity, ensuring the stability of the filling process, and optimizing product design. Traditional measurement methods usually use mechanical measuring devices, whose core structure includes a measuring rod and a stabilizing plate to keep the measuring rod vertical. In specific operation, the stabilizing plate has a movable groove inside, and the measuring rod is slidably connected to the stabilizing plate through the movable groove. The stabilizing plate is used to place flat on the mouth of the glass bottle, so that the measuring rod is inserted along the vertical direction of the glass bottle until the lower end of the measuring rod contacts the inner bottom surface of the glass bottle, and the internal depth is read through the scale of the measuring rod.
[0003] Because different batches of glass bottles have different shapes, the diameter of the bottle mouth will vary greatly. When the size of the stabilizing plate (especially the width of the support structure in contact with the bottle mouth) is smaller than the actual inner diameter of the bottle mouth, especially for large-diameter glass bottles, the stabilizing plate cannot be placed on the bottle mouth. This causes the measuring rod to lose horizontal support during insertion. The measuring rod will be radially offset due to gravity or external operating force, or even completely detached from the central axis of the bottle mouth, resulting in a large measurement error. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a depth measuring tool for glass bottles. The purpose is to solve the technical problem that when the size of the stabilizing plate is smaller than the actual inner diameter of the bottle mouth, the stabilizing plate cannot be placed on the bottle mouth, causing the measuring rod to lose horizontal support during insertion. The measuring rod will then be radially offset due to gravity or external operating force, or even completely detach from the central axis of the bottle mouth, resulting in a large measurement error.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A depth measuring tool for glass bottles includes a connecting base. The connecting base has a first movable groove inside, and a measuring rod is slidably connected inside the first movable groove. A fixed base is located at the bottom of the connecting base. The fixed base has a second movable groove inside, communicating with the first movable groove. A stabilizing plate is located at the bottom of the fixed base, and the stabilizing plate is used to abut against the mouth of the glass bottle. A third movable groove is located inside the stabilizing plate, communicating with the second movable groove. The lower end of the measuring rod passes through the second movable groove and exits through the third movable groove. A measuring scale is provided on one side of the measuring rod. Multiple connecting blocks are located at the top of the stabilizing plate. Multiple connecting slots are located at the bottom of the fixed base, and the multiple connecting blocks are inserted into the multiple connecting slots. Multiple first locking holes are located along the outer edge of the fixed base, each communicating with one of the multiple connecting slots. A second locking hole is located inside each connecting block, and a locking bolt passes through the first locking hole, threadedly engaging with the adjacent second locking hole.
[0007] When measuring large-diameter glass bottles, the connecting block at the top of the stabilizing plate and the connecting slot at the bottom of the fixing base are plugged in and fastened by threaded bolts passing through the first and second locking holes. This design allows for the replacement of stabilizing plates of different sizes according to the inner diameter of the glass bottle mouth. The replacement can be done quickly by simply removing the locking bolts, which makes it easy to place the stabilizing plate at the mouth of large-diameter glass bottles and ensures the stability of the measuring rod during measurement.
[0008] Furthermore, in this application, the bottom of the stabilizing plate is provided with an installation groove, and an anti-slip plate is adhered inside the installation groove. The bottom of the anti-slip plate is provided with a frosted surface, which is used to contact the mouth of the glass bottle.
[0009] The frosted surface of the anti-slip plate contacts the mouth of the glass bottle through micro-textured bumps and grooves. The mechanical interlocking effect between the rough surfaces increases static friction, so that when the stabilizing plate is placed at the mouth of the bottle, it can resist the lateral force generated by the shaking or tilting of the bottle mouth during the insertion of the measuring rod. This ensures that the stabilizing plate always stays in place with the mouth of the bottle and prevents the measuring rod from tilting due to the displacement of the stabilizing plate.
[0010] Furthermore, in this application, the mounting groove is annular in shape, and the anti-slip plate is shaped to match the mounting groove.
[0011] The mounting groove is designed as a ring, and its shape perfectly matches the bottom contour of the stabilizing plate. This ensures that the contact surface between the anti-slip plate and the mounting groove is evenly distributed along the 360° circumference after the anti-slip plate is embedded. Furthermore, when the stabilizing plate is placed at the bottle mouth, the downward pressure applied by the measuring rod is transmitted to the bottle mouth through the ring-shaped anti-slip plate. Due to the geometric symmetry of the ring, the pressure is evenly distributed along the circumference, avoiding stress concentration on one side that could cause the bottle mouth edge to be deformed by pressure or the anti-slip plate to peel off locally.
[0012] Furthermore, in this application, a fixing hole is provided on one side of the fixing seat, the fixing hole is connected to the second movable groove, and a fixing bolt is threaded into the fixing hole, the fixing bolt abutting against the measuring rod.
[0013] Furthermore, in this application, the lower end of the measuring rod is provided with a movable bottom cavity, the interior of the movable bottom cavity is provided with a mounting plate, the bottom of the mounting plate is provided with a buffer spring, one end of the buffer spring is provided with a movable plate, the buffer spring and the movable plate are located inside the movable bottom cavity, and the bottom of the movable plate extends out of the bottom of the movable bottom cavity.
[0014] Furthermore, in this application, the bottom of the movable plate is provided with a buffer plate, and the buffer plate is elastic.
[0015] Furthermore, in this application, the movable plate is provided with guide sliders on both sides, and the movable bottom cavity is provided with guide grooves on both sides, and the guide sliders on both sides of the movable plate are respectively slidably engaged with the guide grooves on both sides of the movable bottom cavity.
[0016] Furthermore, in this application, the bottom of the mounting plate is provided with a first mounting post, and the two sides of the first mounting post are provided with first latching protrusions. The other end of the buffer spring is inserted into the first mounting post, so that the first latching protrusions on both sides of the first mounting post are engaged with the other end of the buffer spring. The top of the movable plate is provided with a second mounting post, and the two sides of the second mounting post are provided with second latching protrusions. One end of the buffer spring is inserted into the second mounting post, so that the second latching protrusions on both sides of the second mounting post are engaged with one end of the buffer spring.
[0017] Furthermore, in this application, a visible notch is provided on one side of the connecting seat, and the visible notch connects to the first movable slot.
[0018] Furthermore, in this application, the upper end of the measuring rod is provided with a limiting block, the size of which is larger than the size of the first movable groove.
[0019] This utility model has the following beneficial effects:
[0020] When measuring large-diameter glass bottles, the connecting block at the top of the stabilizing plate and the connecting slot at the bottom of the fixing base are plugged in and fastened by threaded bolts passing through the first and second locking holes. This design allows for the replacement of stabilizing plates of different sizes according to the inner diameter of the glass bottle mouth. Replacement can be done quickly by simply removing the locking bolts, thus making it easy to place the stabilizing plate at the mouth of large-diameter glass bottles and ensuring the stability of the packaging measuring rod during measurement.

[0035] Reference Figures 1-9In some specific embodiments, a depth measuring tool for a glass bottle includes a connecting base 2. The connecting base 2 has a first movable groove 7 inside, and a measuring rod 3 is slidably connected inside the first movable groove 7. A fixed base 8 is provided at the bottom of the connecting base 2. The fixed base 8 has a second movable groove 9 inside, communicating with the first movable groove 7. A stabilizing plate 5 is provided at the bottom of the fixed base 8, and the stabilizing plate 5 is used to abut against the mouth of the glass bottle 1. A third movable groove 6 inside the stabilizing plate 5 communicates with the second movable groove 9. The lower end of the measuring rod 3 passes through the second movable groove 9, allowing the measuring rod to... The lower end of 3 extends through the third movable groove 6. The measuring rod 3 has a measuring scale 4 on one side. The top of the stabilizing plate 5 has multiple connecting blocks 12. The bottom of the fixing base 8 has multiple connecting slots 13. The multiple connecting blocks 12 are inserted into the multiple connecting slots 13. The outer edge of the fixing base 8 has multiple first locking holes 14. The multiple first locking holes 14 are respectively connected to the multiple connecting slots 13. The inside of the connecting block 12 has a second locking hole 17. The first locking hole 10 has a locking bolt 15 inserted into it. The locking bolt 15 is threaded into the adjacent second locking hole 17.
[0036] With the above technical solution, when the measuring rod 3 measures the internal depth of the glass bottle 1, the stabilizing plate 5 is placed on the mouth of the glass bottle 1, so that the measuring rod 3 passes through the first movable groove 7 of the connecting seat 2, the second movable groove 9 of the fixed seat 8 and the third movable groove 6 of the stabilizing plate 5 in sequence, forming a three-section sliding channel. Through the coaxial connection of the three grooves, the measuring rod 3 always moves in the vertical direction under the action of gravity. When the measuring rod 3 touches the bottom of the glass bottle 1, the operator can obtain the internal depth dimension of the glass bottle 1 by observing the measuring scale 4 of the measuring rod 3. When it is necessary to measure a large-diameter glass bottle 1, the connecting block 12 at the top of the stabilizing plate 5 and the connecting slot 13 at the bottom of the fixing base 8 are plugged in and fastened by threaded fastening through the first locking hole 14 and the second locking hole 17 by the locking bolt 15. This design allows for the replacement of stabilizing plates 5 of different sizes according to the inner diameter of the bottle mouth of the glass bottle 1 (such as those suitable for 18mm and 25mm diameter glass bottles 1). The replacement can be done quickly by simply removing the locking bolt 15, which makes it easy to place the stabilizing plate 5 at the mouth of the large-diameter glass bottle 1 and improve the stability of the packaging measuring rod 3 during measurement.
[0037] Reference Figures 1-6 In some specific embodiments, the bottom of the stabilizing plate 5 is provided with an installation groove 18, and an anti-slip plate 19 is attached inside the installation groove 18. The bottom of the anti-slip plate 19 is provided with a frosted surface 20, which is used to contact the mouth of the glass bottle 1.
[0038] Through the above technical solution, the frosted surface 20 at the bottom of the anti-slip plate 19 contacts the mouth of the glass bottle 1 through the micro-textured surface. The mechanical interlocking effect between the rough interfaces increases the static friction, so that when the stabilizing plate 5 is placed at the mouth of the bottle, it can resist the lateral force generated by the shaking during the insertion of the measuring rod 3, ensuring that the stabilizing plate 5 always remains in the original position with the mouth of the bottle, and preventing the measuring rod 3 from tilting due to the displacement of the stabilizing plate 5.
[0039] In addition, the anti-slip plate 19 is fixed in the mounting groove 18 at the bottom of the stabilizing plate 5 by adhesive. The adhesive surface covers the entire area of the mounting groove 18 to enhance adhesion. This design avoids the use of rigid fixing methods such as bolts, reducing the risk of the anti-slip plate 19 loosening due to vibration caused by frequent contact with the bottle mouth.
[0040] Reference Figure 6 In some specific embodiments, the mounting groove 18 is annular in shape, and the anti-slip plate 19 is shaped to match the mounting groove 18.
[0041] Through the above technical solution, the mounting groove 18 is designed as a ring, and its shape is completely matched with the bottom contour of the stabilizing plate 5, ensuring that the contact surface between the anti-slip plate 19 and the mounting groove 18 is evenly distributed along the 360° circumference after the anti-slip plate 19 is embedded; and when the stabilizing plate 5 is placed at the bottle mouth, the downward pressure applied by the measuring rod 3 is transmitted to the bottle mouth through the ring anti-slip plate 19. Due to the geometric symmetry of the ring, the pressure is evenly distributed along the circumference, avoiding stress concentration on one side that could cause the edge of the glass bottle 1 to be deformed by pressure or the anti-slip plate 19 to peel off locally.
[0042] Reference Figures 1-6 In some specific embodiments, a fixing hole 10 is provided on one side of the fixing seat 8. The fixing hole 10 is connected to the second movable groove 9. A fixing bolt 11 is threaded into the fixing hole 10 and abuts against the measuring rod 3.
[0043] With the above technical solution, when the measuring rod 3 reaches the bottom of the glass bottle 1, the measuring rod 3 can be temporarily locked by tightening the fixing bolt 11. This prevents the operator from reading the measuring scale 4 or removing the measuring rod 3, as slight hand shaking may cause the measuring rod 3 to retract or continue to press down, resulting in reading deviation.
[0044] Reference Figures 7-9 In some specific embodiments, the lower end of the measuring rod 3 is provided with a movable bottom cavity 21, the interior of the movable bottom cavity 21 is provided with a mounting plate 22, the bottom of the mounting plate 22 is provided with a buffer spring 27, one end of the buffer spring 27 is provided with a movable plate 23, the buffer spring 27 and the movable plate 23 are located inside the movable bottom cavity 21, and the bottom of the movable plate 23 extends out of the bottom of the movable bottom cavity 21.
[0045] With the above technical solution, when the lower end of the measuring rod 3 contacts the bottom of the glass bottle 1, the buffer plate 25 (elastic material such as rubber or silicone) first contacts the bottom of the glass bottle 1, and absorbs the initial impact energy through its own deformation, so as to prevent the hard measuring rod 3 from directly hitting the bottom of the bottle and prevent the bottom of the glass bottle 1 from being damaged by the impact force of the measuring rod 3.
[0046] Furthermore, during measurement, since the bottom of the movable plate 23 protrudes from the bottom of the movable bottom cavity 21, when the lower end of the measuring rod 3 touches the inner bottom surface of the glass bottle 1, the measuring rod 3 needs to be continuously moved downward until the movable plate 23 is pushed into the interior of the movable bottom cavity 21, thereby preventing the protrusion of the movable plate 23 from causing deviation in the measured value.
[0047] Reference Figures 7-9 In some specific embodiments, the bottom of the movable plate 23 is provided with a buffer plate 25, which is elastic.
[0048] Through the above technical solution, when the buffer plate 25 contacts the bottom of the bottle, its elastic deformation expands the contact surface from "point contact" to "surface contact", the pressure distribution is more uniform, the pressure on the local area of the inner bottom surface of the glass bottle 1 is reduced, and the glass bottle 1 is prevented from breaking due to stress concentration.
[0049] Reference Figures 7-9 In some specific embodiments, guide sliders 24 are provided on both sides of the movable plate 23, and guide grooves 26 are provided on both sides of the movable bottom cavity 21. The guide sliders 24 on both sides of the movable plate 23 are slidably engaged with the guide grooves 26 on both sides of the movable bottom cavity 21.
[0050] Through the above technical solution, when the buffer plate 25 contacts the bottom of the irregular glass bottle 1, the lateral force is transmitted to the guide groove 26 through the guide groove 26, which avoids the movable plate 23 directly pressing the buffer spring 27 to cause lateral bending and protects the axial elastic performance of the buffer.
[0051] Reference Figure 9 In some specific embodiments, the bottom of the mounting plate 22 is provided with a first mounting post 28, and the two sides of the first mounting post 28 are provided with first latching protrusions 29. The other end of the buffer spring 27 is inserted into the first mounting post 28, so that the first latching protrusions 29 on both sides of the first mounting post 28 are engaged with the other end of the buffer spring 27. The top of the movable plate 23 is provided with a second mounting post 30, and the two sides of the second mounting post 30 are provided with second latching protrusions 31. One end of the buffer spring 27 is inserted into the second mounting post 30, so that the second latching protrusions 31 on both sides of the second mounting post 30 are engaged with one end of the buffer spring 27.
[0052] Through the above technical solution, the first latching protrusions 29 on both sides of the first mounting post 28 are latched to the other end of the buffer spring 27, and the second latching protrusions 31 on both sides of the second mounting post 30 are latched to one end of the buffer spring 27, so that the protruding structures of the first latching protrusions 29 and the second latching protrusions 31 are embedded in the coil gap of the buffer spring 27, forming a mechanical interlock to prevent the buffer spring 27 from axially dislodging when compressed or rebounding.
[0053] Reference Figures 1-6 In some specific embodiments, a visible notch 32 is provided on one side of the connecting seat 2, and the visible notch 32 connects to the first movable groove 7.
[0054] Through the above technical solution, the visible notch 32 opened on one side of the connecting seat 2 is connected to the first movable groove 7, forming an open window that directly reaches the sliding area of the measuring rod 3 from the outside. The operator can directly observe the position of the measuring rod 3 in the first movable groove 7 without disassembling the connecting seat 2. The operator can directly compare the measuring scale 4 with the reference line through the visible notch 32 to ensure the accuracy of the initial position and reduce the number of trial and error.
[0055] Reference Figures 1-4 In some specific embodiments, the upper end of the measuring rod 3 is provided with a limiting block 16, the size of which is larger than the size of the first movable groove 7.
[0056] With the above technical solution, when the measuring rod 3 slides up and down in the first movable groove 7 of the connecting seat 2, the limiting block 16, because its size is larger than the first movable groove 7, will be blocked by the edge of the first movable groove 7 when it slides to the limit position, forcibly stopping the movement of the measuring rod 3, thereby preventing the measuring rod 3 from leaving the first movable groove 7.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
