Abstract
Description
Technical Field
[0001] This utility model belongs to the field of corrugated pipe thickness detection technology, and in particular relates to a PVC corrugated pipe wall thickness detection device. Background Technology
[0002] PVC corrugated pipe is a pipe made of polyvinyl chloride as the main raw material through extrusion or blow molding process. Its inner and outer walls have a corrugated structure, which not only has the rigidity of PVC material, but also gives the pipe good flexibility, making it easy to bend and install. During the production of PVC corrugated pipe, its thickness needs to be measured by measuring device.
[0003] Currently, existing testing equipment can usually only measure the wall thickness of PCV corrugated pipes at a single point. To ensure the accuracy of the measurement, a multi-point sampling method is used when testing the wall thickness of PCV corrugated pipes. This requires staff to repeatedly perform multiple measurement-fixing-measurement-adjustment operations to complete the measurement of multiple measurement points. The measurement rate is low, and it is impossible to guarantee the uniform distribution of measurement points.
[0004] To address the aforementioned issues, this application proposes a PVC corrugated pipe wall thickness testing device. Utility Model Content
[0005] The purpose of this invention is to provide a PVC corrugated pipe wall thickness detection device, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a PVC corrugated pipe wall thickness testing device, comprising a fixed plate and multiple clamping blocks circumferentially arranged on one side of the fixed plate. The clamping blocks are fixedly connected to a connecting block, and the connecting block is respectively arranged in a through groove on the fixed plate. The corrugated pipe is sleeved on the clamping blocks. The movement of the connecting block causes the clamping blocks to move away from each other and clamp against the inner wall of the corrugated pipe. Multiple sets of abutting blocks are circumferentially arranged on one side of the fixed plate. Each set of abutting blocks includes two abutting blocks fixedly connected to symmetrically arranged telescopic sleeves. The two telescopic sleeves are symmetrically arranged and slidably connected to two connecting rods respectively. The connecting rods are fixedly connected to an adjusting seat and a sliding seat respectively. One side of the adjusting seat is provided with a sliding seat that is slidably connected to a U-shaped connecting seat. Each set of abutting blocks abuts against the inner and outer walls of the corrugated pipe.
[0008] Furthermore, the sliding seat passes through the through slot three of the adjusting seat, and a scale line is provided on one side of the U-shaped connecting seat. The end faces of the two abutting blocks in each group that are close to each other are respectively on the same horizontal plane as the zero scale line of the scale line and the side of the sliding seat away from the central axis of the fixed plate.
[0009] Furthermore, a screw rod two, which is threadedly connected to the sliding seat, is rotatably installed inside the U-shaped connecting seat, and two meshing bevel gears are provided outside the U-shaped connecting seat. One bevel gear is connected to the screw rod two through a rotating shaft, and the other bevel gear is connected to the knob through a rotating shaft.
[0010] Furthermore, the adjusting seat is set in the through groove two opened in the fixed plate, and the top of the adjusting seat is rotatably installed with a screw three threadedly connected to the fixed plate, and the top of the screw three is provided with a knob. The fixed plate is provided with a smooth groove two communicating with the through groove two, and the two sides of the adjusting seat are provided with slider two slidably connected to the smooth groove two.
[0011] Furthermore, a screw is fixed on the side of the fixed plate away from the clamping block, and the screw is threadedly connected to an internal threaded ring on the outer wall with a connecting ring rotatably installed. Both the connecting block and the internal threaded ring are equipped with hinge seats that are respectively hinged to both ends of the connecting rod.
[0012] Furthermore, the connecting block is disposed in the through groove of the fixed plate, and the connecting block is provided with sliders on both sides that are slidably connected to the smooth groove of the fixed plate.
[0013] Furthermore, the telescopic sleeve has multiple internal threaded holes evenly spaced laterally, and the connecting rod has an internal threaded groove with the same diameter as the internal threaded holes.
[0014] Furthermore, a hand-held lever is fixed to one end of the screw away from the fixed plate.
[0015] This utility model has the following beneficial effects:
[0016] The connecting block of this utility model can move, thereby driving the abutment block to move. One end of the corrugated pipe is sleeved on the outside of the abutment block. The connecting block drives the abutment blocks to move away from each other, so that the abutment block abuts against the inner wall of the corrugated pipe to fix the corrugated pipe. The abutment block can fix corrugated pipes with different inner diameters.
[0017] This invention uses two contact blocks to contact the inner and outer walls of the bellows respectively. The distance between the two contact blocks is the wall thickness of the bellows. The contact blocks are arranged in multiple sets and distributed in a circumferential array, which can simultaneously measure the bellows at multiple points. The telescopic sleeve can slide relative to the screw to adjust the horizontal position of the contact blocks, so that the contact blocks can measure the wall thickness of the bellows at different horizontal positions.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0030] Please see Figure 1 — Figure 6 As shown, this utility model is a PVC corrugated pipe wall thickness detection device, including a fixed plate 3 and multiple abutting blocks 5, which are circumferentially arranged on one side of the fixed plate 3. The abutting blocks 5 are fixedly connected to connecting blocks 4, and the connecting blocks 4 are respectively arranged in the through grooves 301 opened in the fixed plate 3. The corrugated pipe is sleeved on the abutting blocks 5. The movement of the connecting blocks 4 causes the abutting blocks 5 to move away from each other and abut against the inner wall of the corrugated pipe. Multiple sets of abutting blocks 15 are circumferentially arranged on one side of the fixed plate 3. Each set of abutting blocks 15 includes two abutting blocks 15 that are fixedly connected to symmetrically arranged telescopic sleeves 14. The two telescopic sleeves 14 are symmetrically arranged and slidably connected to two connecting rods 13. The connecting rods 13 are fixedly connected to the adjusting seat 9 and the sliding seat 10, and one side of the adjusting seat 9 is provided with a sliding seat 10 that is slidably connected to a U-shaped connecting seat 11. Each set of abutting blocks 15 abuts against the inner and outer walls of the corrugated pipe.
[0031] This embodiment provides a PVC corrugated pipe wall thickness detection device. During measurement, one end of the corrugated pipe is fitted over the clamping block 5. The connecting block 4 moves the clamping blocks 5 away from each other, so that the clamping blocks 5 are pressed against the inner wall of the corrugated pipe, thus fixing the corrugated pipe. Multiple sets of clamping blocks 15 are evenly distributed, enabling multi-point measurement of the corrugated pipe and ensuring uniform distribution of sampling points. After the corrugated pipe is fixed, the two clamping blocks 15 in each set are located on the inner and outer sides of the corrugated pipe, respectively. The adjusting seat 9 can move, causing the connecting rod 13 fixed to it to move. This causes the telescopic sleeve 14, which is slidably connected to the connecting rod 13, and its fixed contact block 15 to move and contact the outer wall of the bellows. The sliding seat 10 can drive one connecting rod 13 to move, thereby causing the telescopic sleeve 14, which is slidably connected to the connecting rod 13, and its fixed contact block 15 to move and contact the inner wall of the bellows. The distance between the two contact blocks 15 is the wall thickness of the bellows. The telescopic sleeve 14 can slide to adjust the horizontal position of the contact block 15, so that the contact block 15 can measure the wall thickness of the bellows at different horizontal positions.
[0032] The sliding seat 10 passes through the through slot 902 of the adjusting seat 9. The U-shaped connecting seat 11 has a scale line 1101 on one side. The end faces of the two abutting blocks 15 in each group that are close to each other are on the same horizontal plane as the zero scale line of the scale line 1101 and the side of the sliding seat 10 away from the central axis of the fixed plate 3. The end face of the abutting block 15 away from the central axis of the fixed plate 3 that is close to the other abutting block 15 is on the same horizontal plane as the central axis. The end face of the abutting block 15 that is close to the central axis of the fixed plate 3 that is close to the other abutting block 15 is on the same horizontal plane as the side of the sliding seat 10 away from the central axis of the fixed plate 3. After the two abutting blocks 15 abut against the inner and outer walls of the bellows, the distance between the end faces of the two abutting blocks 15 that are close to each other can be read directly through the scale line 1101.
[0033] The U-shaped connecting seat 11 has a screw rod 12 rotatably installed inside, which is threadedly connected to the sliding seat 10. The U-shaped connecting seat 11 has two meshing bevel gears 17 on its outside. One bevel gear 17 is connected to the screw rod 12 through a rotating shaft, and the other bevel gear 17 is connected to a knob through a rotating shaft. The top of the U-shaped connecting seat 11 has a rotating shaft that connects the connecting seat to the bevel gears 17 and rotates them. By rotating the knob, the two bevel gears 17 are rotated, which in turn drives the screw rod 12 to rotate, thereby moving the sliding seat 10.
[0034] The adjusting seat 9 is disposed in the through groove 302 of the fixed plate 3, and the top of the adjusting seat 9 is rotatably mounted with a screw 16 threadedly connected to the fixed plate 3. The top of the screw 16 is provided with a knob. The fixed plate 3 is provided with a smooth groove 3021 communicating with the through groove 302. The two sides of the adjusting seat 9 are provided with sliders 901 that are slidably connected to the smooth groove 3021. The knob can drive the screw 16 to rotate, thereby driving the adjusting seat 9 to move. The sliders 901 and the smooth groove 3021 cooperate to guide the movement of the adjusting seat 9.
[0035] Among them, the fixed plate 3 is fixedly provided with a screw 2 on the side away from the clamping block 5, and the screw 2 is threadedly connected to the internal threaded ring 7 on which the connecting ring 8 is rotatably installed on the outer wall. The connecting block 4 and the internal threaded ring 7 are both provided with hinge seats and are respectively hinged to the two ends of the connecting rod 6. Rotating the internal threaded ring 7 drives the connecting ring 8 to move laterally, thereby driving the connecting block 4 to move through the connecting rod 6.
[0036] The connecting block 4 is disposed in the through groove 301 opened in the fixed plate 3, and the connecting block 4 is provided with sliders 401 on both sides and is slidably connected to the smooth groove 3011 opened in the fixed plate 3. The sliders 401 and the smooth groove 3011 cooperate to guide the movement of the connecting block 4.
[0037] The telescopic sleeve 14 has multiple internal threaded holes 1401 evenly spaced laterally, and the connecting rod 13 has an internal threaded groove 1301 with the same diameter as the internal threaded holes 1401. The internal threaded groove 1301, the internal threaded holes 1401, and the bolts work together to fix the telescopic sleeve 14 and the connecting rod 13. By aligning the internal threaded holes 1401 at different positions with the internal threaded groove 1301 and then tightening the bolts, the horizontal position of the abutment block 15 can be adjusted.
[0038] The screw 2 is fixed with a hand handle 1 at the end away from the fixed plate 3, which is convenient for the user to hold.
[0039] It is understandable that this utility model can fix corrugated pipes with different inner diameters, and secondly, it can perform multiple sampling points with one fixing, and ensure that the sampling points are evenly distributed.
[0040] A specific application of the operation process in this embodiment is as follows: one end of the bellows is sleeved on the outside of the clamping block 5. The internal thread ring 7 is rotated to drive the connecting ring 8 away from the hand handle 1, which further drives the connecting rod 6 and the connecting block 4 to move, thereby driving the clamping blocks 5 to move away from each other and to be clamped and fixed against the inner wall of the bellows. At this time, the two abutting blocks 15 of each group should be located on the inner and outer sides of the bellows respectively. Then, the knob is rotated to drive the screw 16 to rotate, thereby driving the abutting block 15 outside the bellows to move and abut against the outer wall of the bellows. Then, the knob is rotated to drive the bevel gear 17 to rotate, thereby driving the abutting block 15 inside the bellows to move and abut against the inner wall of the bellows. The distance between the end faces of the two abutting blocks 15 approaching each other is read by the scale line 1101 on the side of the sliding seat 10 away from the central axis of the fixed plate 3.
