Description

Technical Field

[0001] The utility model relates to the technical field of measuring tool processing, in particular to a measuring tool calibration mechanism. Background Art

[0002] A measuring tool refers to a measuring tool used to measure the size of an object. There are many types of measuring tools, which can measure the length, width, height, outer diameter, inner diameter, angle, depth and other dimensions of an object, making it easier for staff to draw drawings and check the accuracy of workpieces. After each measuring tool is produced and used for a long time, its accuracy will inevitably deviate, so the user needs to calibrate the accuracy of the measuring tool.

[0003] The correction of measuring tool accuracy is mainly adjusted manually by the user. Since the user needs to grasp the measuring tool and calibrate its accuracy, once the hand slips or fails to grasp it, it is easy to affect the calibration work. To avoid this phenomenon, the existing application number is 202320927565.9, a caliper measuring tool calibration device. This technical scheme clamps the vernier caliper through a clamping structure, thereby avoiding the displacement of the caliper when the user calibrates the vernier caliper. However, the clamping method of this technical scheme is mainly to clamp the vernier caliper by rotating the thread structure. First, the user needs to rotate it several times when clamping and loosening the vernier caliper. If this device is used in the production line, the user is prone to hand soreness and other discomforts due to frequent rotation of the thread structure. Second, the device mainly clamps and limits the vernier caliper by friction. Once the user fails to tighten the thread or the user uses too much force during the calibration process, the vernier caliper is still prone to displacement. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a measuring tool calibration mechanism to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a measuring tool calibration mechanism, comprising a base, a first bracket and a second bracket, a limiting assembly is arranged inside the second bracket, and the limiting assembly includes a push plate, a first spring is connected to the lower part of the first bracket, and a clamping plate is connected to the top of the first spring, a limiting groove is provided on one side of the clamping plate, a second spring is connected to one side of the first bracket, and one end of the second spring is connected to a limiting block, and a pull rope is connected between the limiting block and the push plate.

[0006] By adopting the above technical solution, the tail end of the vernier caliper is first inserted into the second bracket. When the vernier caliper is fully inserted, the push plate completely pulls the limit block out of the limit groove through the pull rope. At this time, the first spring drives the card plate to move up and abut against the head end of the vernier caliper. The card plate cooperates with the second bracket to avoid the front and back, left and right displacements and vertical and horizontal flipping of the vernier caliper. The installation operation is time-saving and labor-saving, and the non-friction limiting function makes it difficult for the vernier caliper to shift even if too much force is used during the proofreading work. When disassembling, you only need to press down the card plate to end the limiting of the vernier caliper, and then directly take out the vernier caliper.

[0007] Furthermore, the push plate is slidably connected to the second bracket, and the limit block is slidably connected to the first bracket.

[0008] By adopting the above technical solution, the vernier caliper is pulled out from the second bracket. At this time, the push plate is no longer held back by the vernier caliper. The limit block is driven to move leftward into the limit groove by the second spring. At the same time, the limit block drives the push plate to move leftward through the pull rope.

[0009] Furthermore, the clamping plate is slidably connected to the first bracket.

[0010] By adopting the above technical solution, after the vernier caliper is calibrated, the user presses down the clamping plate with one hand to end the limiting of the head end of the vernier caliper, and then the user directly pulls the vernier caliper out of the second bracket with the other hand.

[0011] Furthermore, four pulleys are provided on the outer surface of the second bracket, and the pull rope is in contact with the pulleys on the outer surface of the second bracket.

[0012] By adopting the above technical solution, when the vernier caliper is fully inserted, the push plate completely pulls the limit block out of the limit groove through the pull rope, and guides the pull rope through the pulley.

[0013] Furthermore, a vernier caliper is connected between the second bracket and the clamping plate, and the first bracket and the second bracket are respectively connected to two sides of the top of the base.

[0014] By adopting the above technical solution, the vernier caliper is installed between the second bracket and the clamping plate, so as to avoid the vernier caliper from being displaced forward, backward, left, right, and vertically or horizontally flipped.

[0015] Furthermore, a groove is provided on an upper side of one side of the second bracket, and the vernier caliper is detachably connected to the second bracket.

[0016] By adopting the above technical solution, the tail end of the vernier caliper is inserted into the second bracket. When the vernier caliper is fully inserted, the push plate completely pulls the limit block out of the limit groove through the pull rope.

[0017] Furthermore, the vernier caliper abuts against the clamping plate.

[0018] By adopting the above technical solution, the first spring drives the card plate to move up and resist the head end of the vernier caliper. The card plate cooperates with the second bracket to prevent the vernier caliper from being displaced forward, backward, left, right, and vertically or horizontally flipped. The installation operation is time-saving and labor-saving, and non-friction limiting is used.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model arranges the second bracket and the limit assembly, firstly inserts the tail end of the vernier caliper into the second bracket, and when the vernier caliper is fully inserted, the push plate completely pulls the limit block out of the limit groove through the pull rope, at this time the first spring drives the card plate to move up and abut against the head end of the vernier caliper, and the card plate cooperates with the second bracket to avoid the vernier caliper from being displaced front and back, left and right, and flipped vertically and horizontally, so the installation operation is time-saving and labor-saving, and the non-friction force limit is used, so even if the proofreading work is too forceful, it is not easy to cause the vernier caliper to shift, and when disassembling, it is only necessary to press down the card plate to end the limit of the vernier caliper, and then directly take out the vernier caliper; the disassembly and assembly operation is convenient and the structure is simple, and at the same time, due to the non-friction force limit, the vernier caliper is difficult to shift.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A measuring tool calibration mechanism, such as Figure 1-Figure 4As shown, it includes a base 1, a first bracket 2 and a second bracket 3, and a limiting component 5 is arranged inside the second bracket 3.

[0029] Specifically, the limiting assembly 5 includes a push plate 501 that passes through the upper part of the outer surface of the second bracket 3, a limiting groove 505 is provided on one side of the clamping plate 503, a second spring 507 is connected to one side of the inside of the first bracket 2, one end of the second spring 507 is connected to the limiting block 506, a pull rope 502 is connected between the limiting block 506 and the push plate 501, four pulleys are provided on the outer surface of the second bracket 3, the pull rope 502 contacts the pulleys on the outer surface of the second bracket 3, and when the tail end of the vernier caliper 4 is fully inserted into the second bracket 3, the push plate 501 just pulls the limiting block 506 out of the limiting groove 505 completely through the pull rope 502; a first spring 504 is connected to the lower part of the inside of the first bracket 2, and a clamping plate 503 is connected to the top of the first spring 504, and the first spring 504 drives the clamping plate 503 to move up and abut against the head end of the vernier caliper 4, and the clamping plate 503 cooperates with the second bracket 3 to prevent the vernier caliper 4 from being displaced forward, backward, left, right, and vertically or horizontally flipped.

[0030] See also Figure 1 and Figure 2 In the above embodiment, a vernier caliper 4 is connected between the second bracket 3 and the clamping plate 503, the first bracket 2 and the second bracket 3 are respectively connected to the top two sides of the base 1, a groove is opened on the upper side of the second bracket 3, and the vernier caliper 4 is detachably connected to the second bracket 3. After the user installs the vernier caliper 4, the vernier caliper 4 can be calibrated by a calibration standard dedicated to the vernier caliper 4.

[0031] See also Figure 1-Figure 4 In the above embodiment, the vernier caliper 4 is in contact with the clamping plate 503, the clamping plate 503 is slidably connected to the first bracket 2, and the first spring 504 drives the clamping plate 503 to move up and abut against the head end of the vernier caliper 4; the push plate 501 is slidably connected to the second bracket 3, and the tail end of the vernier caliper 4 is inserted into the second bracket 3 so that the push plate 501 is pushed; the limit block 506 is slidably connected to the first bracket 2, and the limit block 506 is driven to move to the left and enter the limit groove 505 by the second spring 507.

[0032] The implementation principle of this embodiment is as follows: first, the user inserts the tail end of the vernier caliper 4 into the second bracket 3 so that the push plate 501 is pushed. When the tail end of the vernier caliper 4 is fully inserted into the second bracket 3, the push plate 501 just completely pulls the limit block 506 out of the limit groove 505 through the pull rope 502, and the second spring 507 is compressed. Then the first spring 504 drives the clamping plate 503 to move up and abut against the head end of the vernier caliper 4. The clamping plate 503 cooperates with the second bracket 3 to prevent the vernier caliper 4 from being displaced forward, backward, left, right, and vertically flipped. The installation operation is time-saving and labor-saving, and it is non-frictional limiting. Therefore, even if the user uses too much force during the calibration work, it is not easy to cause the vernier caliper 4 to deviate. After that, the user can calibrate the vernier caliper 4 through the calibration standard dedicated to the vernier caliper 4;

[0033] After the vernier caliper 4 is calibrated, the user presses down the card plate 503 with one hand, thereby ending the limit on the head end of the vernier caliper 4. At the same time, the first spring 504 is compressed. Then the user directly pulls out the vernier caliper 4 from the second bracket 3 with the other hand. At this time, the push plate 501 is no longer resisted by the vernier caliper 4, and the limit block 506 is driven to move to the left into the limit groove 505 by the second spring 507. At the same time, the limit block 506 drives the push plate 501 to move to the left through the pull rope 502. After pulling out the vernier caliper 4, the user stops pressing down the card plate 503. Since the card plate 503 is limited by the limit block 506, the card plate 503 will not be pushed out by the first spring 504.
