Description

Technical Field

[0001] The invention relates to the field of fishing rod production, and in particular to an inner and outer diameter length measuring device for fishing rod production. Background Art

[0002] Fishing rod is one of the indispensable tools for many fishing enthusiasts. In order to catch different fish, fishing rods are also classified accordingly. Different types of fishing rods also have different specifications and sizes. In the traditional fishing rod production process, the inner and outer diameters of fishing rods are usually measured by manual handheld measuring tools, such as micrometers, vernier calipers and outside diameter calipers, which are clamped on the outer surface of the fishing rod for measurement. This method has the advantages of low measurement accuracy, slow efficiency and easy to be affected by the operator's operation, resulting in measurement errors.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the inner and outer diameter measuring devices of fishing rods. In order to make a more accurate comparison, for example, a Chinese patent with publication number CN219674985U discloses an inner and outer diameter measuring device, including a measuring plate, a motor, a screw and a measuring tube, etc.; when in use, two adaptation rings are placed inside the fishing rod, and the motor drives the screw to rotate until the outer walls of the two adaptation rings abut against the inner wall of the fishing rod, and the inner diameter of the fishing rod is measured by the scale lines on the measuring tube; when the inner wall of the fishing rod abuts against the outer walls of the two adaptation rings, the second measuring plate is moved to both sides to contract the spring, and then the second adaptation ring under the second measuring plate is pressed against the outer diameter of the fishing rod, the second measuring plate is released, the spring loses its restriction and stretches, the fishing rod is clamped and then the outer diameter of the fishing rod is measured by the measuring rod.

[0004] However, the above measuring device still has some shortcomings in actual use:

[0005] 1. When the above device measures the inner and outer diameters of a fishing rod, it is necessary to drive the two adaption rings to press against the inner wall of one end of the fishing rod, and to make the two second adaption rings press against the outer wall of one end of the fishing rod, so as to complete the measurement of the inner and outer diameters of the fishing rod. However, due to the relative position limitation of the distance between the adaption rings and the measuring tube, when measuring the inner and outer diameters of the fishing rod, only the inner and outer diameters near the end of the fishing rod can be measured, and the inner and outer diameters at other positions on the fishing rod cannot be measured. Therefore, when in use, the inner and outer diameters at any position on the fishing rod cannot be effectively measured, thereby reducing the usability of the device when in use.

[0006] 2. When the above device is in use, only one end of the fishing rod is tightened and limited by the adaptation ring and the second adaptation ring. Therefore, when the inner and outer diameters of the fishing rod are measured by the device without additionally limiting the fishing rod, the fishing rod can be easily caused to deviate by external interference, thereby causing errors in the measurement results and reducing the accuracy of the measurement results.

[0007] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing devices for measuring the inner and outer diameters of fishing rods. Summary of the invention

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 To Attachment Fig.12 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0038] The embodiment of the present application discloses an inner and outer diameter length measuring device for the production of fishing rods, and it is explained that the inner and outer diameter length measuring device for the production of fishing rods is mainly used in the process of measuring the inner and outer diameters of fishing rods, and technically achieves the measurement of the inner and outer diameters of the fishing rods to be measured at the same time; in particular, when measuring the inner and outer diameters of the fishing rods, the fishing rods to be measured can be clamped and limited by self-centering to avoid the deviation of the fishing rods caused by external forces during measurement, thereby causing inaccurate measurement results; further, the inner and outer diameter length measuring device for the production of fishing rods, while measuring the inner and outer diameters of the fishing rods to be measured, also assists the staff in proofreading the measurement results to avoid the problem of deviation in the measurement results.

[0039] Example 1: Reference Figure 1 As shown, a device for measuring inner and outer diameters of fishing rods for production includes a horizontal panel 1, a measuring piece 2 and a stopper 3. The horizontal panel 1 is provided with the measuring piece 2 for measuring the inner and outer diameters of the fishing rod, and the side of the horizontal panel 1 away from the measuring piece 2 is also provided with the stopper 3 for clamping the fishing rod. When in use, after the stopper 3 clamps the fishing rod to be measured, the clamped fishing rod is driven through the measuring piece 2, and the inner and outer diameters of the fishing rod can be measured at the same time.

[0040] Reference Figures 2 to 4As shown, the measuring piece 2 is used to measure the inner and outer diameters of the fishing rod; specifically, the measuring piece 2 includes a mounting seat 20, a measuring tube 21 and a measuring head 22. The mounting seat 20 is arranged on the horizontal panel 1, and the upper limit of the mounting seat 20 is provided with a measuring tube 21 with an annular structure. The inner circle of the measuring tube 21 forms a measuring circle, and a plurality of measuring heads 22 arranged in the measuring circle are evenly penetrated circumferentially on the measuring tube 21, wherein any one of the measuring heads 22 is pressed against the outer side surface of the fishing rod to form a measuring point, and the diameter of the circumscribed circle jointly constructed at all the measuring points is the outer diameter of the fishing rod, and a plurality of scale marks corresponding to the measuring head 22 are arranged on the outer wall of the measuring tube 21.

[0041] When in use, first read the scale mark of the initial position of the measuring head 22 when the fishing rod is not placed to obtain L0, and by making all the measuring heads 22 press against the outer surface of the fishing rod to be measured, by reading the scale mark at the corresponding position on the outer surface of the measuring tube 21 at this time to obtain L1, the measurement of the outer diameter of the fishing rod is completed, and the outer diameter 2* (L0-L1) of the fishing rod is obtained; as an optional embodiment, the number of measuring heads 22 should be at least not less than three. In this embodiment, the number of measuring heads 22 is set to three, and the three measuring heads 22 are evenly distributed in the circumference and form an equilateral triangle with each other. After contacting the fishing rod to be measured, the fishing rod can be more stably clamped therein to prevent the fishing rod from being disturbed by external forces, thereby affecting the accuracy of the measurement results.

[0042] Reference Figure 3 As shown, the measuring tube 21 is hollow inside, and a connecting strip 23 is sleeved on one end of the measuring head 22 placed in the measuring tube 21. The two ends of the connecting strip 23 slide out of the measuring tube 21 and correspond to any scale mark. When in use, since the fishing rod itself has a certain taper, when the fishing rod is driven through the measuring tube 21 for measurement, the measuring head 22 is always pressed against the outer side of the fishing rod, and moves in the vertical direction along the outer side of the fishing rod as the fishing rod moves. The movement of the measuring head 22 drives the connected connecting strip 23 to slide in the measuring tube 21, and the connecting strip 23 passes through the end of the measuring tube 21, indicating the scale mark at the corresponding position. At this time, the scale mark indicated by the connecting strip 23 is the size of the connected measuring head 22 (i.e., L1).

[0043] Reference Figure 3 and Figure 4As shown, the measuring head 22 is also sleeved with a limit frame 24 connected to the inner side wall of the measuring tube 21, and the connecting strip 23 is symmetrically connected with a driven block 240, and a guide slide bar 241 connected to the limit frame 24 is slidably penetrated on the driven block 240, and an adjustment spring 242 located between the connected driven block 240 and the limit frame 24 is sleeved on the guide slide bar 241. When in use, the measuring head 22 moves to drive the connected connecting strip 23 to move in the vertical direction, and the movement of the connecting strip 23 drives the connected driven block 240 to move, and the adjustment spring 242 is compressed by force. After the adjustment spring 242 is compressed, a driving and pressing force is provided to the connected driven block 240, the connecting strip 23 and the measuring head 22 to always press against the outer side of the fishing rod, thereby increasing the accuracy of the measurement result.

[0044] Reference Figures 5 to 7 As shown, a measuring branch chain 25 for measuring the inner diameter of the fishing rod to be measured is also provided in the measuring circle. The measuring branch chain 25 includes a mounting plate 250, a measuring rod 251, a telescopic strip 252, a connecting support rod 253 and a guide plate 254. A mounting plate 250 is provided in the inner circle of the measuring cylinder 21. A plurality of measuring rods 251 corresponding to the measuring head 22 are circumferentially penetrated on the mounting plate 250. The measuring rods 251 are pressed against the inner wall of the fishing rod to be measured to measure the inner diameter of the fishing rod. The mounting plate 250 is provided with a plurality of measuring rods 251 corresponding to the measuring head 22. The measuring rods 251 are pressed against the inner wall of the fishing rod to be measured to measure the inner diameter of the fishing rod. A telescopic strip 252 is symmetrically arranged on 50, which is limitedly connected to the mounting seat 20 and has a bent structure. A connecting strut 253 is symmetrically extended from one end of the mounting plate 250 away from the measuring tube 21. A guide plate 254 is arranged at one end of all the connecting struts 253 away from the mounting plate 250. The guide plate 254 is simultaneously sleeved on all the limiting sleeve rods 261. A plurality of scale marks corresponding to the limiting sleeve rods 261 are also arranged on the guide plate 254. The guide plate 254 is connected to the telescopic strip 252.

[0045] When in use, by making a plurality of measuring rods 251 close to the inner wall of the fishing rod to be measured, the distance between the end face of the measuring rod 251 in contact with the inner wall of the fishing rod and the axis of the fishing rod is the inner radius of the fishing rod, that is, the number of scales on the guide plate 254 where the measuring rod 251 is located is L2, then the inner diameter R of the fishing rod is 内 =2L2.

[0046] Reference Figure 3 As shown, the measuring rod 251 includes a measuring bar 260, a limiting sleeve rod 261, a limiting slide rod 262 and a ball 263. The measuring bar 260 is arranged in a bent structure. The limiting sleeve rod 261 is slidably sleeved on the horizontal section of the measuring bar 260, the mounting plate 250 is sleeved on the limiting sleeve rod 261, and a limiting slide rod 262 is slidably penetrated on the vertical section of the measuring bar 260. The ball 263 is rollingly arranged on the end of the limiting slide rod 262 away from the connected measuring bar 260.

[0047] When in use, the fishing rod to be measured is moved so that the measuring bar 260 and the limiting sleeve 261 are inserted into the fishing rod, so that the ball 263 on the bent section of the measuring bar 260 presses against the inner wall of the fishing rod. When the fishing rod moves, the friction stress generated between the inner wall of the fishing rod and the ball 263 drives the ball 263 to rotate, and the friction between the measuring bar 260 and the inner wall of the fishing rod is reduced by the rolling of the ball 263, thereby avoiding the problem that the measuring bar 260 and the inner wall of the fishing rod are out of the pressing state due to excessive friction between the measuring bar 260 and the fishing rod when the measuring bar 260 presses against the inner wall of the fishing rod, thereby affecting the accuracy of the measurement result.

[0048] When the fishing rod is driven to slide along the axial direction of the measuring tube 21, the end face of the fishing rod away from the limiting plate 30 comes into contact with the mounting plate 250, and simultaneously pushes the mounting plate 250, the connecting strut 253, the limiting sleeve 261 and the guide plate 254 to slide in the direction away from the measuring tube 21. The movement of the guide plate 254 drives the telescopic strip 252 to extend in the direction away from the measuring tube 21, and the limiting sleeve 261 slides along the outer surface of the connected measuring strip 260 in the direction away from the measuring tube 21. The measuring strip 260 stays in the fishing rod and remains motionless in the horizontal direction because the ball 263 connected thereto is adsorbed and pressed against the inner wall of the fishing rod by the measuring head 22. With the axial sliding of the fishing rod, the inner and outer diameters at any position on the fishing rod can be measured.

[0049] Reference Figure 6 As shown, the outer side surface of any one of the limiting sleeve rods 261 is sleeved with a driving tooth plate 255, and both sides of the driving tooth plate 255 in the length direction are meshed with driven gears 256 rotatably connected to the mounting plate 250, and the driven gears 256 are respectively meshed with driven tooth plates 257 connected to the remaining limiting sleeve rods 261, and the two driven tooth plates 257 are respectively located on both sides of the driving tooth plate 255 and are cross-distributed.

[0050] Reference Figure 5As shown, the mounting plate 250 is provided with limiting sliding grooves 258 corresponding to the plurality of limiting sleeve rods 261 one by one, and the plurality of limiting sliding grooves 258 are distributed circumferentially on the mounting plate 250 . When in use, the driving tooth plate 255 and one of the limit sleeve rods 261 connected thereto are moved to slide in the direction close to the inner wall of the fishing rod. The driving tooth plate 255 will slide in the limit slide groove 258 connected thereto, and drive the driven gears 256 on both sides thereof to rotate synchronously. The sliding path of the limit sleeve rod 261 is limited by the limit slide groove 258, and the driven gear 256 rotates to drive the driven tooth plate 257 meshing with it to slide, so that the driven tooth plate 257 drives the connected limit sleeve rod 261 to slide in the direction close to the inner wall of the fishing rod, thereby achieving the effect of making all the limit sleeve rods 261 on the mounting plate 250 slide synchronously in the direction close to the inner wall of the fishing rod until they are simultaneously pressed against the inner wall of the fishing rod, thereby achieving the effect of increasing the accuracy of the measurement results.

[0051] Reference Figure 3 As shown, the measuring head 22 is made of a material with magnetic adsorption capability, and the ball 263 is made of a metal material that allows the measuring head 22 to be magnetically adsorbed. When in use, when the positions of the measuring bar 260 and the measuring head 22 correspond one to one, the magnetic adsorption of the measuring head 22 causes the ball 263 and the connected limit slide bar 262 to slide toward the inner wall of the fishing rod. Due to the magnetic adsorption of the ball 263 by the measuring head 22, the ball 263 always contacts the inner wall of the fishing rod. At this time, the distance from the end face of the ball 263 to the axis of the measuring tube 21 is the inner radius of the fishing rod, thereby further increasing the accuracy of the measurement result.

[0052] Reference Figure 8 As shown, the limit member 3 is used for limiting and clamping the fishing rod; specifically, the limit member 3 includes a limit plate 30, an active rod 31, a rotating disk 32, a spiral slide 33, a passive block 34, a mounting side plate 35 and a limit frame plate 36. The limit plate 30 is arranged on the horizontal panel 1, and the active rod 31 is passed through the limit plate 30. The end of the active rod 31 close to the mounting seat 20 is provided with a rotating disk 32, and the end of the rotating disk 32 away from the active rod 31 is provided with a spiral slide 33 with a scroll structure. A plurality of passive blocks 34 circumferentially distributed with the active rod 31 as the axis are slidably arranged on the spiral slide 33. The end of the passive block 34 away from the rotating disk 32 is provided with a mounting side plate 35, and a limit frame plate 36 is provided on the mounting side plate 35. When in use, the active rod 31 is driven to rotate, and the rotation of the active rod 31 drives the rotating disk 32 and the spiral slide 33 to rotate. After the spiral slide 33 rotates, the multiple passive blocks 34 drive the connected mounting side plates 35 and the limit frame plates 36 to move towards each other through the spiral slide 33, so that the multiple limit frame plates 36 are pressed against the outer surface of the fishing rod to be measured, thereby achieving the effect of clamping and limiting the fishing rod.

[0053] When it is necessary to release the clamping limit of the fishing rod, it is only necessary to drive the rotating disk 32 and the spiral slide bar 33 in reverse to rotate, so that the passive block 34 can drive the connected mounting side plate 35 and the limit frame plate 36 to slide away from each other, thereby breaking contact with the fishing rod and completing the effect of releasing the limit of the fishing rod.

[0054] Reference Figures 8 to 10 As shown, an arc plate 37 is rotatably provided on the limit frame plate 36. When in use, when the limit frame plate 36 drives the connected arc plate 37 to press against the outer side of the fishing rod, the arc plate 37 deflects with the connecting axis between the limit frame plate 36 so as to be more closely fitted to the outer side of the fishing rod. Further, in order to increase the friction between the arc plate 37 and the fishing rod to be measured, a rubber pad can be further provided on the side of the arc plate 37 away from the connected limit frame plate 36, or a plurality of friction lines can be provided on the arc plate 37 to increase the friction between the arc plate 37 and the outer side of the fishing rod.

[0055] Example 2: Reference Fig. 9 and Fig.10 As shown, on the basis of Example 1, in order to improve the accuracy of the results after measuring the inner and outer diameters of the fishing rod, a limiting disk 38 is rotatably arranged on the rotating disk 32, and a plurality of guide grooves are evenly arranged circumferentially on the limiting disk 38, and the plurality of guide grooves correspond to the passive blocks 34 one by one, and the passive blocks 34 are inserted in the guide grooves, and a plurality of ear blocks 380 are evenly arranged circumferentially on the limiting disk 38, and a limiting rod 381 connected to the limiting plate 30 is slidably penetrated on the ear block 380, and the limiting rod 381 is evenly arranged with a plurality of arc-shaped convex strips of flexible material in the circumference, and a plurality of extension rods 382 slidably inserted on the rotating disk 32 are evenly arranged in the circumference at one end of the limiting disk 38 close to the rotating disk 32, and a receiving groove concentrically arranged with the rotating disk 32 is formed on the limiting plate 30.

[0056] When the locking cam 380 is engaged with the locking cam 381, the locking cam 380 and the locking cam 381 engage with the locking cam 382, ​​and the locking cam 382 engages with the locking cam 382.

[0057] When in use, the fishing rod is manually placed in the middle of several mounting side plates 35, and then the active rod 31 and the rotating disk 32 are driven to rotate. After the rotating disk 32 rotates, the passive block 34 slides toward each other through the spiral slide bar 33 of the rotating disk 32, and the movement of the passive block 34 drives the connected mounting side plates 35, the limiting frame plates 36 and the arc plate 37 to slide toward the direction of the middle fishing rod, until all the limiting frame plates 36 and the arc plate 37 are pressed against the outer surface of the fishing rod, thereby completing the effect of clamping and limiting the fishing rod.

[0058] The active rod 31 is then driven in the reverse direction to rotate, and the active rod 31 and the rotating disc 32 are moved in the direction away from the limit plate 30 at the same time, so that the rotating disc 32 is disengaged from the accommodating groove, and the limit rod 381 and the arc-shaped convex strip are disengaged from the ear block 380, thereby releasing the limit on the ear block 380 and the limiting disc 38. When the rotating disc 32 and the limiting disc 38 slide in the direction away from the limit plate 30, the friction force between the arc-shaped convex strip and the ear block 380 will drive the ear block 380 and the limiting disc 38 to slide in the direction close to the rotating disc 32 during the process of the arc-shaped convex strip and the ear block 380 disengaging, so that the limiting disc 38 is re-attached to the outer surface of the rotating disc 32, and the extension rod 382 is reinserted on the rotating disc 32.

[0059] At this time, when the rotating disc 32 is driven to rotate, the rotating disc 32 also drives the limiting disc 38, the passive block 34, the mounting side plate 35, the limiting frame plate 36, the arc plate 37 and the fishing rod to rotate synchronously, so that the fishing rod rotates at different angles along the three measuring heads 22 and the outer side surfaces of the ball 263. At this time, by observing the positions of the measuring heads 22 and the connecting strips 23 at the scale marks on the measuring tube 21 when the fishing rod rotates at different angles, a number of L2s are obtained, that is, the measuring heads 22 form a number of measuring points on the outer side surface of the fishing rod, and the diameter of the circumscribed circle formed between all the measuring points is the outer diameter of the fishing rod. By comparing the diameter of the circumscribed circle with 2*(L0-L1), the measurement results of the outer diameter and inner diameter of the fishing rod can be calibrated.

[0060] Further, refer to Fig.11 and Fig.12 As shown, the measuring head 22 includes a connecting tube 220 and a spherical head 221. The connecting tube 220 and the spherical head 221 are both hollow inside and connected to each other. The spherical head 221 is made of a material with magnetic adsorption ability. A discharge port is provided on the side of the spherical head 221 away from the connecting tube 220. A ball 222 with a spherical structure is rotatably arranged in the discharge port. One end of the connecting tube 220 away from the connected spherical head 221 passes through the limit frame 24, the connecting strip 23 and the measuring tube 21. Dyeing pigments are stored in the chambers inside the connecting tube 220 and the spherical head 221.

[0061] It should be noted that the rotation axis between the ball 222 and the discharge port is set perpendicular to the axial direction of the measuring cylinder 21. Therefore, when the fishing rod is driven to slide along the axial direction of the measuring cylinder 21, the ball 222 will not be driven to rotate, thereby smearing the dye in the spherical head 221 on the outer surface of the fishing rod. When the fishing rod stops sliding axially and instead rotates around the axis of the measuring cylinder 21, the friction between the fishing rod and the ball 222 will drive the ball 222 to rotate, thereby smearing the dye on the fishing rod.

[0062] During use, when the fishing rod is driven to rotate, the adjusting spring 242 drives the connected driven block 240, the connecting strip 23, the connecting tube 220 and the spherical head 221 to press against the outer side of the fishing rod, so that the rotation of the fishing rod drives the ball 222 to rotate in the spherical head 221 through the friction between its outer side surface and the ball 222, thereby smearing the dyeing pigment in the spherical head 221 on the outer side of the fishing rod. Therefore, after the fishing rod rotates one circle, by observing whether the dyeing pigment on the outer side of the fishing rod forms a complete circle, it can more conveniently assist the staff to judge and proofread the measurement results, thereby improving the accuracy of measuring the inner and outer diameters of the fishing rod. At the same time, it can also make it easier for the staff to distinguish the fishing rods with accurate measurement results, which is convenient for subsequent unified processing.

[0063] Based on the above, when measuring the inner and outer diameters of the fishing rod, the outer diameter value R 外 =2*(L0-L1), the inner diameter of the fishing rod is R 内 =2*L2, so when the wall thickness of the measured fishing rod is known, R 外 Subtract the wall thickness to get the inner diameter of the fishing rod. 内 Proofreading, without knowing the wall thickness of the fishing rod, through R 外 Subtract R 内 The wall thickness of the fishing rod can be obtained, and the outer diameter and inner diameter of the fishing rod can be calibrated by observing whether the dyeing pigment on the outer side of the fishing rod forms a complete circle.

[0064] During operation: The first step is to place the fishing rod in the inner circle of the measuring tube 21 and at the same time perform self-centering limit clamping on the fishing rod through the limit member 3 to complete the preliminary limit clamping of the fishing rod to be measured.

[0065] Step 2: When the fishing rod is placed in the inner circle of the measuring tube 21, the measuring heads 22 distributed circumferentially on the measuring tube 21 are pressed against the outer side of the fishing rod. At the same time, the measuring rod 251 is inserted into the fishing rod. The measuring heads 22 adsorb the ball 263 on the measuring rod 251. Based on this, the position of the connecting strip 23 at the scale mark on the measuring tube 21 is the outer radius of the fishing rod, and the position of the measuring rod 251 at the scale mark on the guide plate 254 is the inner radius of the fishing rod. At the same time, the circumferentially and correspondingly distributed measuring heads 22 and measuring rods 251 can further clamp and limit the fishing rod.

[0066] Step 3: During the measurement process, by driving the limit member 3 to rotate, the rotation of the limit member 3 will drive the clamped fishing rod to rotate at the same time, so that the measuring head 22 will apply the dye to the outer surface of the fishing rod, thereby assisting the staff to proofread the measurement results more easily.
