Description

Technical Field

[0001] This utility model relates to the field of silicone tube inner diameter detection technology, specifically a high-precision silicone tube inner diameter detection device. Background Technology

[0002] Silicone tubing is a tubular product made of silicone rubber, characterized by high temperature resistance, aging resistance, non-toxicity, odorlessness, and good flexibility. Its smooth inner wall makes it resistant to impurities and exhibits strong chemical stability, resisting corrosion from various acids, alkalis, and oils. It is widely used in medical fields (such as infusion tubing and drainage tubes), the food industry (beverage delivery, pharmaceutical piping), electronics and electrical appliances (cable protection, insulating sleeves), and mechanical and chemical industries, becoming a common flexible connection component in both industrial and daily life due to its excellent performance.

[0003] Existing silicone tube inner diameter measuring devices often place the measuring device on one side of the silicone tube and measure the inner diameter of the silicone tube by moving two pointers and observing their position on the scale line. However, there is no fixing device between the silicone tube and the measuring device. When the silicone tube moves, the position of the measuring device and the silicone tube deviates, which will cause errors in the measured value of the inner diameter of the silicone tube and affect the measurement effect.

[0004] To address this issue, we designed a high-precision silicone tube inner diameter testing device. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision silicone tube inner diameter detection device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-precision silicone tube inner diameter detection device, including a detection plate, a mounting shell fixedly installed on the top of the detection plate, a rotating motor fixedly installed on one side of the mounting shell, a bidirectional screw rotatably installed inside the mounting shell, a connecting rod threaded onto the outer side of the bidirectional screw, a slider fixedly connected to the bottom of the connecting rod, a contact block fixedly connected to the bottom of the slider, and two connecting rods symmetrically arranged inside the mounting shell.

[0007] Furthermore, a drive motor is fixedly installed at the top center of the detection plate, and a drive gear is rotatably installed at the bottom of the detection plate. The drive end of the drive motor is fixedly connected to the drive gear. A rack is meshed with one side of the drive gear, and a locking block is fixedly connected to one side of the rack. An abutment rod is fixedly connected to the bottom of the locking block.

[0008] Furthermore, the top of the detection plate is fixedly provided with scale lines, and one side of the snap-fit ​​block is fixedly connected with a pointer, and the number of pointers is set to two.

[0009] Furthermore, a guide groove is provided at the bottom of the detection plate, and a guide slider is fixedly connected to the side of the rack near the detection plate, and the guide slider is fixedly connected to the guide groove.

[0010] Furthermore, a snap-fit ​​groove is provided on one side of the snap-fit ​​block, and the snap-fit ​​block is slidably connected to the detection plate through the snap-fit ​​groove.

[0011] Furthermore, the shape of the contact block is set to semi-circle.

[0012] Furthermore, the pointer is shaped like a triangle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: starting the rotating motor causes the bidirectional screw to rotate, bringing the two contact blocks closer together. The contact blocks are located inside the silicone tube. Then, starting the rotating motor causes the bidirectional screw to reverse until the two contact blocks move away from each other and approach the inner wall of the silicone tube, where they abut against the inner wall. This allows the detection plate to be fixed on one side of the silicone tube, so that the inner diameter of the silicone tube can be obtained by measuring the difference in position of the two pointer tips on the scale line.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a high-precision silicone tube inner diameter detection device, including a detection plate 1, a mounting shell 2 fixedly installed on the top of the detection plate 1, a rotating motor 3 fixedly installed on one side of the mounting shell 2, a bidirectional screw 7 rotatably installed inside the mounting shell 2, a connecting rod 5 threadedly connected to the outer side of the bidirectional screw 7, a slider 4 fixedly connected to the bottom of the connecting rod 5, and an abutment block 6 fixedly connected to the bottom of the slider 4. There are two connecting rods 5, symmetrically arranged inside the mounting shell 2. The abutment block 6 is semi-circular in shape.

[0021] In practice, before use, the operator can first start the rotating motor 3 to rotate the bidirectional screw 7, causing the connecting rod 5 to move relative to each other, bringing the two contact blocks 6 closer together. Then, the operator can place the detection plate 1 at the opening of the silicone tube whose inner diameter is to be measured, so that the two contact blocks 6 are inside the silicone tube. Subsequently, the rotating motor 3 is started, causing the bidirectional screw 7 to rotate in the opposite direction until the two contact blocks 6 move away from each other and approach the inner wall of the silicone tube, abutting against the inner wall of the silicone tube. The rotating motor 3 is then turned off, allowing the detection plate 1 to be fixed on one side of the silicone tube. The inner diameter of the silicone tube can then be obtained by measuring the difference in position of the two pointers 13 on the scale line 15. The contact block 6 is designed to be semi-circular, so that when the contact block 6 contacts the silicone tube, the semi-circular arc surface of the contact block 6 abuts against the silicone tube without damaging the inner wall of the silicone tube. A protrusion is fixedly connected to one side of the connecting rod 5, and a limiting groove is opened on one side of the inner wall of the mounting shell 2. The connecting rod 5 is slidably connected to the protrusion and the limiting groove.

[0022] See Figure 1-4 A drive motor 8 is fixedly installed at the top center of the detection plate 1, and a drive gear 9 is rotatably installed at the bottom of the detection plate 1. The drive end of the drive motor 8 is fixedly connected to the drive gear 9. A rack 10 is meshed with one side of the drive gear 9, and a locking block 11 is fixedly connected to one side of the rack 10. A contact rod 12 is fixedly connected to the bottom of the locking block 11. A guide groove 14 is provided at the bottom of the detection plate 1, and a guide slider 4 is fixedly connected to the side of the rack 10 near the detection plate 1. The guide slider 4 is fixedly connected to the guide groove 14. A locking slot is provided on one side of the locking block 11, and the locking block 11 is slidably connected to the detection plate 1 through the locking slot.

[0023] In practice, the drive motor 8 can be started to rotate the drive gear 9. When the drive gear 9 rotates, the racks 10 on both sides of the drive gear 9 mesh with the drive gear 9. The racks 10 slide at the bottom of the detection plate 1. There are two racks 10, which are symmetrically arranged on both sides of the drive gear 9 and mesh with both sides of the drive gear 9 respectively. When the racks 10 move, they drive the locking block 11, the contact rod 12 and the pointer 13 to move synchronously. The two contact rods 12 move synchronously inside the silicone tube. After the contact rods 12 contact the silicone tube, the drive motor 8 is turned off. The position of the two pointers 13 on the detection plate 1 is observed. According to the value on the scale line 15, the difference between the position of the two pointers 13 at the sharp corners on the scale line 15 is calculated, and the inner diameter of the silicone tube can be obtained.

[0024] See Figure 1-4 The top of the detection plate 1 is fixedly provided with a scale line 15, and a pointer 13 is fixedly connected to one side of the snap-fit ​​block 11. There are two pointers 13. The pointers 13 are triangular in shape.

[0025] In specific implementation, based on the above implementation, pointers 13 are respectively set on both sides of the scale line 15, and can move relative to each other on both sides of the scale line 15. The scale line 15 is marked with numerical values. The staff can determine the inner diameter of the silicone tube by observing the difference between the positions indicated by the two pointers 13. In the vertical direction, the abutment rod 12 is located at the center of the pointer 13 so that the position indicated by the abutment rod 12 and the tip of the pointer 13 is synchronized. The pointer 13 is set as a triangle, and the tip of the pointer 13 is opposite to the scale line 15.

[0026] Working principle: Before use, the operator can first start the rotating motor 3 to rotate the bidirectional screw 7, which drives the connecting rod 5 to move relative to each other, bringing the two contact blocks 6 closer together. Then, the operator can place the detection plate 1 at the opening of the silicone tube whose inner diameter is to be measured, so that the two contact blocks 6 are inside the silicone tube. Then, start the rotating motor 3 to rotate the bidirectional screw 7 in the opposite direction until the two contact blocks 6 move away from each other and approach the inner wall of the silicone tube, abutting against the inner wall of the silicone tube. Then, turn off the rotating motor 3. At this time, the drive motor 8 can be started to rotate the drive gear 9. When the driving gear 9 rotates, the racks 10 on both sides of the driving gear 9 mesh with the driving gear 9 respectively. The racks 10 slide at the bottom of the detection plate 1. When the racks 10 move, they drive the locking block 11, the contact rod 12 and the pointer 13 to move synchronously. The two contact rods 12 move synchronously inside the silicone tube. After the contact rods 12 contact the silicone tube, the drive motor 8 is turned off. The position of the two pointers 13 on the detection plate 1 is observed. According to the value on the scale line 15, the difference between the position of the two pointers 13 at the sharp corners on the scale line 15 is calculated, and the inner diameter of the silicone tube can be obtained.
