[0001] The utility model relates to the technical field of calipers, in particular to a sealing ring deep groove caliper. Background Art

[0002] Sealing rings are commonly used in various types of sealing environments, such as hydraulic, pneumatic or water power systems. In these systems, the size and shape of the sealing ring are critical to the sealing performance and normal operation of the system. Therefore, by measuring the size of the deep groove inside the sealing ring, it can be ensured that the installed sealing ring matches the system requirements and can adapt to the shape and size of the deep groove. The current measurement method generally adopted is to measure with a caliper, and the existing caliper has a fixed length of measuring claws, which cannot effectively measure the deep groove inside the sealing ring with a longer depth, reducing the measurement effect of the measuring caliper.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a sealing ring deep groove caliper.

[0025] The utility model provides Figure 1-3 A sealing ring deep groove caliper shown in the figure comprises a compound ruler body 1 and a measuring frame 2 slidably arranged on the outside of the ruler body 1, upper measuring claws 3 are fixedly arranged at the bottom of the ruler body 1 and the measuring frame 2, a fixing plate 4 is fixedly arranged on the upper end of the outer side of the upper measuring claw 3, a screw 5 is rotatably passed through the inside of the fixing plate 4, an internal threaded sleeve of the outer side of the screw 5 is provided with an internal threaded tube 6, a lower measuring claw 7 is fixedly arranged on the lower end of the outer side of the internal threaded tube 6, two lower measuring claws 7 are arranged in coordination, a limiting ring 8 is fixedly arranged on the lower end of the two upper measuring claws 3 away from each other, a guide rod 9 is slidably passed through the inside of the limiting ring 8, and the guide rod 9 is fixedly connected to the lower measuring claw 7.

[0026] When measuring the deep groove inside the sealing ring, the two screws 5 can be rotated at the same time, so that the internal threaded tube 6 drives the lower measuring claw 7 to move under the sliding support of the guide rod 9 and the limit ring 8, so that the distance between the upper measuring claw 3 and the lower measuring claw 7 can be adjusted, so that the caliper can be extended into the deep groove at a deeper position in the sealing ring for measurement, thereby improving the versatility of the caliper.

[0027] In order to enable the screw rod 5 to rotate stably, Figure 1 As shown, the upper ends of the two screw rods 5 are provided with a rotation adjustment mechanism for driving the screw rods 5 to rotate, and the rotation adjustment mechanism includes a vertical rod 10, a sleeve 11 is fixedly provided on the top of the screw rod 5, the lower end of the vertical rod 10 is fixed in the sleeve 11, and a rotating plate 12 is rotatably sleeved on the upper end.

[0028] When the lower measuring claw 7 needs to be moved longitudinally, the vertical rod 10 can be rotated so that the vertical rod 10 drives the screw rod 5 to rotate stably under the fixed connection of the sleeve 11, so that the screw rod 5 can drive the internal threaded tube 6 and the lower measuring claw 7 to move longitudinally.

[0029] In order to be able to adjust the longitudinal position of the two lower measuring claws 7 at the same time, Figure 1-2 As shown, a synchronous driving mechanism for driving the two screw rods 5 to rotate simultaneously is provided between two adjacent rotating plates 12, and the synchronous driving mechanism includes a telescopic rod 13, and the telescopic rod 13 is a square telescopic rod. A vertical plate 14 is fixedly provided on the top of the side where the two rotating plates 12 are close to each other, and a rotating rod 15 is rotatably penetrated inside the two vertical plates 14. The telescopic rod 13 is fixedly provided between the two rotating rods 15, and a bevel gear 16 is fixedly provided on one end where the rotating rod 15 and the vertical rod 10 are close to each other. The two adjacent bevel gears 16 are meshed, and a rotating block 17 is fixedly provided on the outer side where the two rotating rods 15 are close to each other.

[0030] When it is necessary to adjust the two lower measuring claws 7 at the same time, any rotating block 17 can be rotated to rotate the telescopic rod 13. Since the telescopic rod 13 is a square telescopic rod, the telescopic rod 13 can drive the two rotating rods 15 to rotate at the same time. At this time, under the engagement of the two adjacent bevel gears 16, the rotating rod 15 can drive the vertical rod 10 to rotate, so that the two screws 5 can be driven to rotate at the same time. At the same time, under the connection of the telescopic rod 13, no matter where the mobile frame 2 moves, the lower measuring claws 7 on both sides can still perform stable longitudinal position adjustment.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
