[0001] The utility model relates to the technical field of measuring instruments, and particularly relates to a measuring instrument for general equipment. Background Technique

[0002] Measuring instruments are instrument devices used to measure various physical quantities (such as length, weight, temperature, pressure, etc.), and they play an important role in fields such as quality control, production process control, and laboratory analysis.

[0003] For example, a vernier caliper with the Chinese patent publication number CN206740013U includes a main scale, a vernier scale is arranged on the main scale, through holes and track grooves are arranged on the vernier scale, a fastening device is arranged on the vernier scale, and the fastening device includes a semi-circular ring, a push switch, a folding rod I, a folding rod II and a push rod. The semi-circular ring is hinged to the folding rod I, the folding rod I is hinged to the folding rod II, and a push rod is connected between the connecting part between the folding rod I and the folding rod II and the push switch.

[0004] When the above-mentioned vernier caliper in the patent is in use, it can only achieve the purpose of improving the measurement accuracy. When the existing vernier calipers are in use, since the vernier scale needs to be positioned by screwing a screw rod during positioning, one hand is required for operation, resulting in the vernier scale being unable to measure accurately. Therefore, a device is needed to improve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a measuring instrument for general equipment to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a measuring instrument for general equipment, including a main scale, a displacement device is slidably sleeved on the outer ring of the main scale, a positioning device is fixedly installed at the rear end of the top of the displacement device, an extension device is slidably installed inside the positioning device, the displacement device includes a vernier scale, a cross bar, a support frame and a magnifying glass, the cross bar is fixedly installed at the top and bottom of the side end of the vernier scale, the support frame is slidably sleeved between the two cross bars, and the magnifying glass is fixedly installed inside the support frame away from the vernier scale.

[0007] Preferably, the positioning device includes a displacement plate, a movable rod, a connecting rod, a support frame and a return spring. The movable rod is slidably inserted into the inner bottom end of the support frame, the displacement plate is fixedly installed at the top end of the movable rod, the return spring is fixedly installed between the support frame and the displacement plate, and the connecting rods are symmetrically fixedly installed at the bottom of the front end of the support frame.

[0008] Preferably, the extension device includes a round rod, a displacement frame and a cross block. The round rods are symmetrically fixedly installed at the inner top end of the displacement frame, and the cross block is fixedly installed at the bottom end of the displacement frame.

[0009] Preferably, the bottom end of the round rod penetrates through the top end of the support frame and is connected to the displacement plate. The connecting rod is fixedly installed at the rear end of the top of the vernier scale, and the vernier scale is slidably sleeved on the outer ring of the main scale.

[0010] Preferably, jacks adapted to the round rod and the displacement frame are symmetrically opened at the top end of the support frame.

[0011] Preferably, a plastic sheet is fixedly installed at the bottom end of the movable rod, and the plastic sheet is vertically aligned with the center of the top end of the main scale.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] When the device is in use, the cross block can be pressed upward, so that the displacement plate and the movable rod can be simultaneously displaced upward through the round rod, thereby facilitating the displacement of the vernier scale. When the vernier scale is displaced to the designated position, the cross block can be released, and the displacement plate is driven to move downward by the return spring, so that the plastic gasket at the bottom end of the movable rod can be fastened to the main scale, thereby preventing the vernier scale from moving again. At the same time, a magnifying glass is installed in the support frame, so that it is convenient for the user to more conveniently observe the numerical value between the vernier scale and the main scale, and complete the work of quickly positioning the vernier scale.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a general equipment measuring instrument, including a main scale 4, a displacement device 1 is slidably sleeved on the outer ring of the main scale 4, a positioning device 2 is fixedly installed at the rear end of the top of the displacement device 1, an extension device 3 is slidably installed inside the positioning device 2, the displacement device 1 includes a vernier scale 5, a cross bar 6, a support frame 7 and a magnifying glass 8, the cross bar 6 is fixedly installed at the top and bottom of the side end of the vernier scale 5, the support frame 7 is slidably sleeved between the two cross bars 6, and the magnifying glass 8 is fixedly installed inside the support frame 7 away from the vernier scale 5.

[0021] The positioning device 2 includes a displacement plate 9, a movable rod 10, a connecting rod 11, a support frame 12 and a return spring 13. The movable rod 10 is slidably inserted into the inner bottom end of the support frame 12. The displacement plate 9 is fixedly installed at the top end of the movable rod 10. The return spring 13 is fixedly installed between the support frame 12 and the displacement plate 9. The connecting rods 11 are symmetrically fixedly installed at the bottom of the front end of the support frame 12. Through a through hole adapted to the movable rod 10 opened at the bottom end of the support frame 12, the movable rod 10 is allowed to slide and displace inside the support frame 12.

[0022] The extension device 3 includes a round rod 14, a displacement frame 15 and a cross block 16. The round rods 14 are symmetrically fixedly installed at the inner top end of the displacement frame 15. The cross block 16 is fixedly installed at the bottom end of the displacement frame 15, which can support the displacement frame 15 to slide up and down.

[0023] The bottom end of the round rod 14 passes through the top end of the support frame 12 and is connected to the displacement plate 9. The connecting rod 11 is fixedly installed at the rear end of the top of the vernier scale 5. The vernier scale 5 is slidably sleeved on the outer ring of the main scale 4, which is convenient for the vernier scale 5 and the main scale 4 to be adapted for equipment measurement.

[0024] The top end of the support frame 12 is symmetrically provided with insertion holes adapted to the round rod 14 and the displacement frame 15, allowing the displacement frame 15 to slide up and down inside the support frame 12.

[0025] A plastic sheet is fixedly installed at the bottom end of the movable rod 10, and the plastic sheet is vertically aligned with the center of the top end of the main scale 4, which can quickly fix the vernier scale 5.

[0026] Working principle: when in use, the user can hold the main ruler 4 and move it to the device to be measured. The user's thumb can press the cross block 16 to move upward. When the cross block 16 moves upward, the displacement frame 15 can be driven to squeeze the round rod 14 and move upward. The round rod 14 penetrates the top of the supporting frame 12 and is connected to the displacement plate 9, so that when the displacement frame 15 moves upward, the movable rod 10 can be driven to move upward through the round rod 14 and the displacement plate 9, causing the movable rod 10 to be out of contact with the top of the main ruler 4. Subsequently, the cross block 16 can be pushed, thereby driving the vernier ruler 5 to slide along the surface of the main ruler 4, thereby avoiding measurement of the equipment. Subsequently, when the measuring claws on the vernier ruler 5 and the main ruler 4 contact the surface of the equipment, the cross block 16 can be released, and the elasticity of the reset spring 13 will drive the displacement plate 9 and the movable rod 10 to move downward quickly and reset until the plastic gasket at the bottom of the movable rod 10 is in contact with the main ruler 4. The ruler 4 is fastened, so that the vernier ruler 5 can be temporarily restricted to the specified position, and when the user needs to read the markings on the main ruler 4 and the vernier ruler 5, the scale lines on the main ruler 4 and the vernier ruler 5 can be magnified through the setting of the magnifying glass 8, so that the user can read the scale lines more clearly. At the same time, the support frame 7 is slidably sleeved on the two cross bars 6, so that the support frame 7 can drive the magnifying glass 8 to slide on the side end of the vernier ruler 5 as a whole, so that the user can identify the scale lines in different areas of the vernier ruler 5. When the measurement work of the equipment is completed, the cross block 16 can be pressed upward again, so that the displacement frame 15 can drive the displacement plate 9 to move upward through the round rod 14, so that the plastic gasket at the bottom end of the movable rod 10 can be disengaged from the main ruler 4, thereby releasing the vernier ruler 5, which is convenient for the vernier ruler 5 to avoid being disengaged from the equipment. At this time, the user can remove the device from the surface of the equipment to complete the work.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
