Description

Technical Field

[0001] This application relates to the field of vernier caliper technology, and in particular to an easy-to-use vernier caliper. Background Technology

[0002] A vernier caliper is a measuring instrument used to measure length, inner and outer diameters, and depth. A vernier caliper consists of two parts: a main scale and a sliding vernier scale attached to the main scale. Additionally, it comprises an upper measuring scale, a lower measuring scale, a depth gauge, and a set screw. The main scale, along with the fixed upper and lower measuring scales on the left, forms a single unit. The vernier scale, along with the movable upper and lower measuring scales on the right, forms another unit fitted onto the main scale and can slide along it.

[0003] In existing technology, when using vernier calipers, the vernier scale can move along the slide of the main scale. When it is necessary to position the vernier scale, its position is generally fixed by tightening the bolt on the vernier scale. This positioning method requires first tightening the bolt, then moving the vernier scale, and then tightening the bolt to fix the position of the vernier scale, which makes the operation process relatively cumbersome and inconvenient. Moreover, when adjusting the position of the vernier scale and then tightening the bolt, the vernier scale is prone to move during the tightening process, which can easily affect the measurement accuracy. Therefore, in order to solve the above problems, a vernier caliper with convenient positioning is proposed. Utility Model Content

[0004] To facilitate the fixing of the main scale and the vernier scale, this application provides a user-friendly vernier caliper.

[0005] The easy-to-use vernier caliper provided in this application adopts the following technical solution:

[0006] A user-friendly vernier caliper includes a main scale, a secondary scale, and a positioning component. The secondary scale has a sliding groove, and the main scale is slidably installed within the sliding groove. The positioning component is used to fix the main scale and the secondary scale together. The positioning component includes a mounting block, a sliding rod, a positioning element, and an elastic element. The mounting block is installed on the main scale, and the sliding rod is installed on the secondary scale. The mounting block has a sliding groove for the sliding rod to slide. The positioning element is installed on the inner wall of the sliding groove, and the bottom wall of the sliding rod has multiple positioning grooves for the positioning element to be inserted into. The elastic element is used to drive the positioning element to be inserted into the positioning groove in its normal state.

[0007] By adopting the above technical solution, the position of the vernier scale on the main scale can be flexibly adjusted by sliding the sliding rod within the sliding groove of the mounting block, thereby meeting the measurement needs of different items. The insertion and engagement of the positioning component with different positioning grooves can quickly fix the vernier scale in a suitable position on the main scale. The elastic force generated by the elastic component ensures that the positioning component is firmly inserted into the positioning groove, enhancing the stability of the vernier scale fixed on the main scale. This avoids the cumbersome operation of traditional bolt positioning methods and reduces the occurrence of measurement accuracy issues caused by the vernier scale moving due to bolt tightening.

[0008] Optionally, the elastic element is a torsion spring, and the positioning element is rotatably mounted on the inner wall of the sliding groove. The elastic force of the torsion spring is used to drive one end of the positioning element to be inserted into the positioning groove. When the positioning element is inserted into the positioning groove, the end of the positioning element near the positioning groove is tilted towards the side of the vernier scale.

[0009] By adopting the above technical solution, the torsion spring provides elastic force to insert one end of the positioning component into the positioning groove, thereby fixing the main scale and the secondary scale. This simplifies the positioning operation, avoids the cumbersome traditional bolt tightening method, and improves ease of use. The positioning component is inclined at the end near the positioning groove, which facilitates the smooth movement of the secondary scale on the main scale. When the secondary scale is pushed, the positioning component can rotate and disengage from the positioning groove, further improving the ease of operation.

[0010] Optionally, the positioning member has a pusher integrally formed on the side away from the positioning groove, and the mounting block is slidably mounted with a pusher rod, one end of which is used to abut against the pusher.

[0011] By adopting the above technical solution, users can easily push the push rod to make it abut against the pushing part, thereby driving the positioning part to rotate and disengage from the positioning groove, so as to adjust the position of the vernier scale relative to the main scale; at the same time, the structure is simple and easy to operate, improving the convenience of using the vernier caliper.

[0012] Optionally, the mounting block is provided with a first spring, the spring force of which is used to move the push rod toward the side away from the pushing part.

[0013] By adopting the above technical solution, the first spring in the mounting block can use its elasticity to move the push rod away from the pushing part. This is beneficial for the push rod to automatically reset when positioning is not required, avoiding accidental contact with the pushing part that would cause the positioning to be released, improving the positioning stability and reliability of the vernier caliper, making operation more convenient, and reducing the trouble of manual reset.

[0014] Optionally, the outer wall of the positioning element is covered with a rubber layer.

[0015] By adopting the above technical solution, the rubber layer can enhance the friction and sealing between the positioning component and the positioning groove, improve the stability of the positioning of the main scale and the auxiliary scale, and reduce the situation of positioning failure caused by vibration and other factors.

[0016] Optionally, the elastic element is configured as a second spring, and the mounting block has a movable groove connected to the sliding groove on the side away from the main scale; the positioning element is movably installed in the movable groove, and a positioning block is integrally formed at one end of the positioning element, and the positioning block is inserted into the positioning groove; the elastic force of the second spring is used to drive the positioning block to be inserted into the positioning groove under normal conditions.

[0017] By adopting the above technical solution, the elastic element is set as a second spring. The elastic force of the second spring is used to make the positioning block normally inserted into the positioning groove, thereby fixing the main scale and the auxiliary scale. This avoids the cumbersome operation of the traditional bolt-tightening positioning method, making the operation more convenient. Moreover, the auxiliary scale will not move due to the bolt-tightening process during the adjustment of the auxiliary scale position, ensuring measurement accuracy.

[0018] Optionally, multiple sets of positioning blocks may be provided.

[0019] By adopting the above technical solution and setting multiple positioning blocks, the stability of the connection between the positioning rod and the positioning slot can be increased.

[0020] Optionally, a first limiting piece is provided at the end of the positioning member away from the mounting block, and the second spring is sleeved on the outer wall of the positioning member, with the two ends of the second spring connected to the first limiting piece and the mounting block respectively.

[0021] By adopting the above technical solution and setting the first limiting piece, the second spring can be set outside the positioning block, so as to facilitate the installation of the second spring on the vernier caliper and reduce production costs.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By interlocking the positioning components with different positioning slots, the vernier scale can be quickly fixed in a suitable position on the main scale; the elastic force generated by the elastic component makes the positioning components firmly inserted in the positioning slots, which enhances the stability of the vernier scale fixed on the main scale; and avoids the problem of cumbersome operation of the traditional bolt positioning method, while reducing the occurrence of the vernier scale moving due to the tightening of bolts, which affects the measurement accuracy.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] Example 1:

[0031] This application discloses an easy-to-use vernier caliper.

[0032] Reference Figure 1 A user-friendly vernier caliper includes a main scale 1, a secondary scale 2, an inner measuring jaw 3, an outer measuring jaw 4, and a positioning component 5. The secondary scale 2 has a slide groove 21, and the main scale 1 is slidably installed in the slide groove 21. The positioning component 5 is used to fix the main scale 1 and the secondary scale 2.

[0033] The outer measuring jaws 4 and the inner measuring jaws 3 are respectively installed on opposite sides of the main scale 1. The inner measuring jaws 3 include two inner measuring scales 31, which are respectively installed on the side of the main scale 1 and the auxiliary scale 2 that are close to each other, and are used to measure the inner diameter of the object. The outer measuring jaws 4 include two outer measuring scales 41, which are respectively installed on the side of the main scale 1 and the auxiliary scale 2 that are close to each other, and are used to measure the outer diameter of the object.

[0034] Simultaneously refer to Figure 2 Specifically, the positioning component 5 includes a mounting block 6, a sliding rod 7, a positioning element 8, and an elastic element 9. The mounting block 6 is mounted on the main scale 1 and located at the end away from the outer measuring jaw 4. The end of the auxiliary scale 2 away from the outer measuring jaw 4 is provided with a connecting block 22. The sliding rod 7 is mounted on the connecting block 22, and the extension direction of the sliding rod 7 is in the same direction as the sliding direction of the main scale 1. The mounting block 6 has a sliding groove 61, and the sliding rod 7 is slidably mounted in the sliding groove 61.

[0035] Reference Figure 2In this embodiment, the inner diameter of the sliding groove 61 is larger than the outer diameter of the sliding rod 7; the positioning member 8 is set in the shape of a plate, and the positioning member 8 is rotatably installed in the sliding groove 61 through the rotating shaft 81; the outer wall of the sliding rod 7 is provided with a plurality of positioning grooves 71 for the end of the positioning member 8 to be inserted into. When the positioning member 8 is inserted into the positioning groove 71, the end of the positioning member 8 near the positioning groove 71 is inclined toward the side of the auxiliary ruler 2.

[0036] The elastic element 9 is a torsion spring 91, which is installed between the positioning plate and the inner wall of the sliding groove 61. The elastic force of the torsion spring 91 is used to drive one end of the positioning element 8 to be inserted into the positioning groove 71 under normal conditions. In addition, the outer peripheral wall of the positioning element 8 is covered with a rubber layer 82, which further increases the stability of the positioning element 8 inserted into the positioning groove 71.

[0037] A sliding part 85 is inclinedly provided on the side of the positioning member 8 away from the positioning groove 71. When the positioning member 8 is inserted into the positioning groove 71, the sliding part 85 abuts against the side of the mounting block 6 away from the auxiliary scale 2. The mounting block 6 has a sliding hole 62, and a push rod 63 is slidably installed in the sliding hole 62. One end of the push rod 63 is used to abut against the sliding part 85. When it is necessary to cancel the abutment between the positioning member 8 and the positioning groove 71, the push rod 63 is slid towards the side of the sliding part 85 and abuts against the sliding part 85, thereby canceling the insertion of the positioning member 8 into the positioning groove 71; the auxiliary scale 2 can slide on the main scale 1.

[0038] A second limiting piece 64 is provided at the end of the push rod 63 away from the pushing part 85. A first spring 65 is sleeved on the outer wall of the push rod 63, and the two ends of the first spring 65 abut against the second limiting piece 64 and the outer wall of the mounting block 6, respectively. The elastic force of the first spring 65 can drive the push rod 63 to move towards the side away from the pushing part 85. When the push rod 63 is not needed to cancel the insertion of the positioning member 8 into the positioning groove 71, the elastic force of the first spring 65 will cause the push rod 63 to return to the initial position. At this time, the positioning member 8 will be inserted into the positioning groove 71 again under the action of the torsion spring 91.

[0039] The implementation principle of Embodiment 1 of this application is as follows:

[0040] When measuring the outer diameter of an object, first adjust the distance between the two measuring scales to be greater than the distance between the outer diameters of the object. Then, align the outer measuring scale 41 on the main scale 1 with the outer diameter of the object. Next, slide the outer measuring scale 41 on the secondary scale 2 toward one side of the object. Since the positioning piece 8 is inserted into the positioning groove 71 at an angle, the positioning piece 8 rotates and disengages from the positioning groove 71, allowing the outer measuring scale 41 on the secondary scale 2 to slide toward one side of the object without obstruction, thus improving the ease of sliding the secondary scale 2. When the outer measuring scale 41 on the secondary scale 2 aligns with the object, stop sliding the secondary scale 2. At this time, the positioning piece 8 is inserted into the positioning groove 71 under the elastic force of the torsion spring 91.

[0041] The positioning component 8 is inserted into the positioning groove 71 under the elastic force of the torsion spring 91, which can avoid the cumbersome operation of the traditional bolt positioning method, and at the same time reduce the occurrence of the situation where the auxiliary scale 2 moves due to the tightening of the bolt, thus affecting the measurement accuracy.

[0042] Example 2:

[0043] This application discloses an easy-to-use vernier caliper.

[0044] Reference Figure 3 and Figure 4 The difference between Embodiment 2 and Embodiment 1 is that: the positioning member 8 is rod-shaped, and the outer diameter of the sliding rod 7 is adapted to the inner diameter of the sliding hole; the end of the mounting block 6 away from the main scale 1 is provided with a movable groove 66 that communicates with the sliding groove 61, and the positioning member 8 is slidably installed in the movable groove 66; a plurality of positioning blocks 83 are integrally formed at the end of the positioning member 8 near the positioning groove 71, and the plurality of positioning blocks 83 are respectively inserted into each positioning groove 71; the insertion and engagement of the positioning blocks 83 and the positioning groove 71 can fix the auxiliary scale 2 and the main scale 1 together.

[0045] The elastic element 9 is set as a second spring 92. The end of the positioning element 8 away from the positioning block 83 is provided with a first limiting piece 84. The second spring 92 is sleeved on the outer wall of the positioning element 8. The two ends of the second spring 92 are respectively connected to the first limiting piece 84 and the bottom of the mounting block 6. The elastic force of the second spring 92 is used to drive the positioning block 83 to be inserted into the positioning groove 71 under normal conditions.

[0046] The implementation principle of Embodiment 2 of this application is as follows:

[0047] The positioning block 83 is normally inserted into the positioning groove 71 by the elastic force of the second spring 92, thus fixing the main scale 1 and the auxiliary scale 2. This avoids the cumbersome operation of the traditional bolt positioning method and makes the operation more convenient. In addition, the auxiliary scale 2 will not move due to the bolt during the adjustment of the position, thus ensuring the measurement accuracy.

[0048] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
