Other meters 10 have data storage and transmission functions that can export measurement data to a computer or mobile device for further processing. The measuring assembly 100 may select different sensors, signal processors and data displays according to actual requirements, and specific arrangements may refer to known techniques.

The substrate 200 is one of the main load bearing parts of the meter 10. The base 200 may be provided in a variety of configurations, and in some embodiments, the base 200 may have a cylindrical profile. In other embodiments, the profile of the substrate 200 may be rectangular. In other embodiments, the outline of the substrate 200 may also be trapezoidal, as the case may be.

The base 200 is connected to the measurement assembly 100. In some embodiments, the base 200 may be fixedly connected to the measurement assembly 100, i.e., the base 200 may carry and protect the measurement assembly 100. In other embodiments, the base 200 may also be slidably coupled to the measurement assembly 100, i.e., the measurement assembly 100 may be movable relative to the base 200 to change the measurement position.

The base 200 defines a receiving cavity 210. In other words, the inside of the base 200 may form the receiving cavity 210, and the receiving cavity 210 is capable of receiving the supporting part 300. The specific structure and size of the receiving chamber 210 are determined according to the supporting part 300.

Referring to fig. 1 to 3, the base 200 is provided with a first opening 220 communicating with the accommodating chamber 210, the first opening 220 being provided for the support 300 to enter and exit the accommodating chamber 210. The shape and size of the first opening 220 are determined according to the receiving cavity 210 and the supporting portion 300, and some embodiments of the present utility model take a circular first opening 220 as an example.

The support 300 is the main load bearing portion of the meter 10 and is capable of supporting the measurement assembly 100. In some embodiments, the supporting portion 300 may be a tripod (including three brackets 330), which has a simple structure and high stability.

The supporting portion 300 is slidably connected with the base 200, that is, the supporting portion 300 can slide relative to the base 200, so that the supporting portion 300 can be located at different connection positions relative to the base 200 according to actual requirements. The support 300 is configured to have a first position and a second position. In the first position, the support 300 is at least partially positioned in the receiving cavity 210, see fig. 3 and 1. In other words, in some embodiments, the support 300 may be partially located in the receiving cavity 210. In other embodiments, the support 300 may also be located entirely within the receiving cavity 210.

Referring to fig. 2, when the support portion 300 is required to provide the support function, the support portion 300 is switched from the first position to the second position, and the support portion 300 protrudes from the accommodating chamber 210 in the first opening 220 in a direction away from the measuring assembly 100. It is understood that the support 300 may partially protrude from the accommodating chamber 210 or may completely protrude from the accommodating chamber 210.

In the embodiment of the present utility model, the measuring instrument 10 includes a measuring assembly 100, a base 200, and a supporting portion 300. When the measuring instrument 10 needs to be stored, the supporting portion 300 can be driven to slide relative to the base 200 along the direction approaching to the measuring assembly 100, so that the supporting portion 300 can extend into the accommodating cavity 210 along the first opening 220. Compared with the measuring instrument 10 which is fixed by the supporting part 300 and cannot be adjusted in a sliding way, the whole space occupation volume of the measuring instrument 10 along the supporting direction of the supporting frame can be reduced, and the whole portability of the measuring instrument 10 is improved. When the support portion 300 is required to provide support, the support portion 300 is driven to extend out of the accommodating cavity 210 from the first opening 220 along a direction away from the measuring assembly 100, so that the measuring assembly 100 can be positioned at a predetermined height position, and related personnel can operate the measuring assembly conveniently. Compared with the supporting part 300 which utilizes a mode of expanding and contracting the multistage slide bars to reduce the volume of the space, the supporting part 300 in the scheme consists of the bracket 330 with balanced structural strength, so that the stability during supporting can be ensured, the abrasion of the supporting part 300 is reduced, and the service life of the measuring instrument 10 is prolonged.

Referring to fig. 1-3, it should be noted that in some embodiments, the substrate 200 is provided with a second opening 230 disposed opposite to the first opening 220. The shape and size of the second opening 230 is dependent on the receiving cavity 210 and the measuring assembly 100. Some embodiments of the utility model take the circular second opening 230 as an example. The second opening 230 communicates with the receiving chamber 210. The second opening 230 is used for the measurement assembly 100 to enter and exit the receiving cavity 210.

The measuring assembly 100 is slidably connected to the base 200, i.e. the measuring assembly 100 is capable of sliding relative to the base 200 to change the measuring position. The measurement assembly 100 is configured to have a third position in which the measurement assembly 100 is at least partially positioned within the receiving cavity 210, and a fourth position, see fig. 3. In other words, in some embodiments, the measurement assembly 100 may be partially located in the receiving cavity 210. In other embodiments, the measurement assembly 100 may also be located entirely within the receiving chamber 210. Depending on the actual situation.

Referring to fig. 2, the measuring assembly 100 protrudes from the receiving cavity 210 at the second opening 230 in a direction away from the support 300 during the switching of the measuring assembly 100 from the third position to the fourth position. It is understood that the measuring assembly 100 may partially extend out of the accommodating chamber 210 through the second opening 230, or may extend out of the accommodating chamber 210 through the second opening 230.

When the measuring apparatus 10 is to be stored, the measuring assembly 100 can be extended into the storage cavity 210 along the direction close to the supporting portion 300 at the second opening 230 on the basis that the supporting portion 300 is accommodated in the storage cavity 210, so that the space occupation volume of the whole measuring apparatus 10 along the supporting direction of the supporting frame is further reduced, and the portability of the whole measuring apparatus 10 is improved. The measurement position of the measuring instrument 10 can be finely adjusted with the support height of the support portion 300 fixed, and the measurement accuracy can be improved.

It will be appreciated that in some embodiments, the base 200 is provided with a spacer 240, see fig. 3. The partition 240 divides the accommodating chamber 210 into a first chamber 211 and a second chamber 212. It should be noted that, the partition 240 may completely partition the first cavity 211 from the second cavity 212, so that the first cavity 211 and the second cavity 212 are completely independent cavities, which avoids interference between the measurement assembly 100 and the support 300, and also prevents dust and sundries carried by the contact between the support 300 and the outside from entering the second cavity 212 where the measurement assembly 100 is located, which affects the measurement accuracy of the measurement assembly 100. In other embodiments, the partition 240 may also partially isolate the first cavity 211 from the second cavity 212. And may be specific to the actual situation.

It should be noted that the first opening 220 may be in communication with the first cavity 211, and the second opening 230 may be in communication with the second cavity 212. The supporting portion 300 is disposed in the first cavity 211, and the measuring assembly 100 is disposed in the second cavity 212. The above arrangement facilitates the support 300 to move in and out of the first cavity 211 at the first opening 220 and the measurement assembly 100 to move in and out of the second cavity 212 at the second opening 230.

In some embodiments, in the first position, the supporting portion 300 is completely accommodated in the accommodating cavity 210, so that the space occupied by the whole measuring apparatus 10 can be further reduced. In other embodiments, in the first position, the supporting portion 300 can be partially accommodated in the accommodating cavity 210, that is, a portion of the supporting portion 300 extends out of the accommodating cavity 210 through the first opening 220, so that the supporting portion 300 can continuously provide a supporting force for the measuring apparatus 10, when the measuring apparatus 10 is supported by the base 200, the base 200 is prevented from directly transmitting jolts in the transportation process to the measuring assembly 100, the measuring accuracy of the measuring assembly 100 is ensured, and the service life of the measuring apparatus 10 is prolonged.

It will be appreciated that in some embodiments, the support 300 has a first slider 310. Specifically, the first slider 310 may be provided at an end of the support 300 near the measuring assembly 100. The number of the first sliders 310 may be single or plural, and the plurality of first sliders 310 may be disposed at intervals. It should be noted that the first sliders 310 may be uniformly spaced or non-uniformly spaced. The plurality of first sliders 310 can ensure the sliding stability of the support 300. The first slider 310 may have various structures, that is, the first slider 310 may have a rectangular shape, a spherical shape, or a cylindrical shape, and some embodiments of the present utility model take the stacked disc-shaped first slider 310 as an example, referring to fig. 3.

The base 200 is provided with a first sliding rail 250 opposite to the first sliding block 310, and the first sliding rail 250 should be disposed at an end portion of the base 200 near the supporting portion 300. It is understood that the structure of the first sliding rail 250 should correspond to the structure of the first sliding block 310, and the number of the first sliding rails 250 should be consistent with the number of the first sliding blocks 310. In some embodiments, the first rail 250 may be provided as a chute. The sliding groove can be directly formed on the base 200, that is, the base 200 and the sliding groove are integrally formed. In other embodiments, the first rail 250 may be formed separately from the base 200, i.e., the first rail 250 may be fixedly attached to the base 200.

It should be noted that, the arrangement direction of the first sliding rail 250 should be parallel to the opposite arrangement direction of the measuring assembly 100 and the supporting portion 300, so that the supporting portion 300 can extend out of or into the accommodating cavity 210 along the direction approaching to the measuring assembly 100 or the direction departing from the measuring assembly 100. It will be appreciated that the length of the first rail 250 should be such as to take the target measurement height of the gauge 10 as an example. I.e. the maximum acquisition height of the gauge 10 is the length of the first rail 250 plus the effective travel distance of the support 300.

The support 300 slides relative to the first rail 250 by the first slider 310, so that the support 300 can be switched between the first position and the second position.

It should be noted that, the end of the first locking member 320 near the supporting portion 300 may further be provided with a transition portion, i.e. along the direction from the supporting portion 300 to the base 200, where the cross-sectional area of the transition portion along the direction perpendicular to the direction from the supporting portion 300 to the base 200 is gradually reduced (i.e. gradually changed). Similarly, the opening portion of the first stopper 270 is also tapered so that the first locking member penetrates the first stopper 270 to position the supporting portion 300.

One end of the first locking member 320 facing away from the supporting portion 300 penetrates into the first limiting portion 270 by means of elastic force generated by compression of the elastic member so as to position the supporting portion 300. It is understood that the first locking member 320 may position the support 300 in a plurality of positions. Specifically, the supporting part 300 may be positioned inside the receiving cavity 210 to enable the receiving of the supporting part 300, and the supporting part 300 may also be positioned outside the receiving cavity 210 to enable the stable support of the supporting part 300 to the base 200.

It is understood that the second sliding rail 260 is similar to the first sliding rail 250, and the second slider 110 is similar to the first slider 310, which will not be described herein. In other embodiments, a worm gear may be secured to the base 200. Specifically, a worm gear may be disposed at an end of the base 200 proximate to the measurement assembly 100. The specific arrangement of the worm gear depends on the weight and construction of the measurement assembly 100. The measurement assembly 100 has a worm opposite the worm gear. In particular, a worm may be provided at the end of the base 200 near the measurement assembly 100. The worm gear is engageable with the worm to enable the measurement assembly 100 to be switched between a third position and a fourth position. The specific arrangement may depend on the actual situation. The above arrangement facilitates the ease with which the measurement assembly 100 extends out of or into the second cavity 212 from the second opening 230, providing Gao Shouna the meter 10.

Referring to fig. 4, it can be appreciated that in some embodiments, the measurement assembly 100 further includes a second lock 120. The second locking member 120 is similar to the first locking member 320, and will not be described in detail herein. The second locking member 120 is resiliently coupled to the measuring assembly 100. Specifically, a spring may be provided near one end of the measurement assembly 100 before the second locking so that the second elastic member has an elastic force away from the measurement assembly 100.

Similarly, the base 200 may be provided with a second limiting portion 280. The second limiting portion 280 depends on the structure of the second locking member 120. The end of the second locking member 120 facing away from the measuring assembly 100 can penetrate into the second limiting portion 280 by means of the elastic force generated by compression of the elastic member, so as to position the measuring assembly 100. It should be noted that the second locking member 120 may position the measurement assembly 100 in a plurality of positions. In particular, the measurement assembly 100 may be positioned within the second cavity 212 to enable stowing of the measurement assembly 100. The measurement assembly 100 may also be positioned outside the second cavity 212 to perform a corresponding detection function.
