DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] As Figure 1 , Figure 2 , Figure 5 and Figure 6 indicate, the specific structure of the utility model is displayed from different perspectives. It is easy to know that the utility model is a digital display indicator. The digital display indicator 1 is mainly used for measuring the dimensional error of a workpiece. In particular, the digital display indicator 1 of the utility model is particularly used in the machining process of a machine tool. Specifically, the digital display indicator 1 includes an indicator body 11. Various measuring structures are installed in the indicator body 11. One of the structures is a measuring head 12 that extends out of the indicator body 11. The measuring head 12 is used for contacting a measuring surface for measurement (the unevenness of the measuring surface will drive the measuring head 12 to fluctuate, achieving measurement). Further, the digital display indicator 1 also includes a display 13 installed on the indicator body 11 for displaying measurement data and a button 14 provided on the indicator body 11 for controlling the program. Specifically, the button 14 of the digital display indicator 1 has multiple buttons, each having a different control function, such as zero setting, setting switching, etc.

[0027] The measuring head 12 of the digital indicating gauge 1 is easy to be damaged by collision, therefore, the utility model also includes the protective device 2 which is elastically connected to the indicating gauge body 11 near the measuring head 12, that is, the protective device 2 is located at the periphery of the measuring head 12, and the protective device 2 is used to cover the measuring head 12 when needed to avoid impact, and can be folded when not needed to not hinder the measurement of the measuring head 12; further, the indicating gauge body 11 is provided with the pull hanging device 3 which is used to pre-hang the indicating gauge body 11 on the machine tool, and the pull hanging device 3 is mainly used when the digital indicating gauge 1 is used on the machine tool, for example, the digital indicating gauge 1 is installed on the machine tool, and the operation of installation is easy to cause falling, at this time, the pull hanging device 3 is hung on the machine tool to prevent the impact caused by landing when falling.

[0028] In order to realize the function that the protective device 2 can be unfolded to cover the measuring head 12 when needed, and can be folded to not hinder the measuring head 12 when not needed, specifically, as shown in Figure 2 and Figure 3 , the protective device 2 includes a plurality of mounting seats 21 which are fixedly installed to the indicating gauge body 11 near the measuring head 12, and a support rod 22 which is elastically connected to the mounting seat 21, more specifically, a blind hole is formed in the mounting seat 21, a spring is placed in the blind hole, and the support rod 22 is installed in the blind hole by abutting against the spring, thereby constituting the elastic connection of the mounting seat 21 and the spring; further, the protective device 2 also includes an end seat 23 which is fixed to the support rod 22, and a sliding connecting piece 24 which is movably connected to the end seat 23, specifically, the end seat 23 forms a through hole, and the sliding connecting piece 24 is arranged in the through hole, and the arrangement is a certain damping arrangement, of course, it can be a non-damping arrangement, at this time, a locking piece 26 is rotatably connected to the part of the support rod 22 close to the end seat 23, and the locking piece 26 is used to lock the sliding of the sliding connecting piece 24, because the sliding connecting piece 24 is easy to slide without damping and does not have the impact resistance; further, a plurality of anti-collision bodies 25 are rotatably connected to the end of the sliding connecting piece 24, the plurality of anti-collision bodies 25 can be unfolded in order to cover and protect the measuring head 12, and the specific state is shown in Figure 7 and Figure 8 , the sliding connecting piece 24 is stretched out, and then the anti-collision bodies 25 are unfolded to form a hollow hemispherical shell which covers the measuring head 12, and the hemispherical shell has a certain elasticity to effectively unload a part of the impact force.

[0029] As shown in Figure 2 and Figure 4As shown, specifically, the pulling and hanging device 3 comprises a mounting shell 31 mounted on the top surface of the indicating meter body 11, a fixing cylinder 32 and a fixing column 33 fixedly mounted in the mounting shell 31, and one end of a connecting rope 34 is fixedly clamped and connected between the fixing cylinder 32 and the fixing column 33; the other end of the connecting rope 34 is connected with the magnet connecting body 5 which can be hung on the machine tool and can be attracted to the machine tool made of iron.

[0030] Although the above protective structure has a protective effect when the digital indicating meter 1 falls, it is still necessary to prevent the falling of the digital indicating meter 1 as much as possible in daily use to better protect the digital indicating meter 1 and improve its service life. Therefore, further optimization is made, and the surface of the indicating meter body 11 is provided with anti-skid lines 15 for preventing the indicating meter body 11 from slipping when being held by hand.

[0031] The digital indicating meter specially matched with the machine tool usually needs to be fixed to the corresponding position of the machine tool through some supports or mounting supports. At this time, some structures capable of being quickly installed are needed, and sometimes the position needs to be adjusted after the digital indicating meter 1 is installed, for example, the side of the display 13 is mistakenly directed towards the inside of the machine tool during installation, which causes the reading to be inconvenient. Therefore, the digital indicating meter needs to have an adjusting function. Therefore, further optimization is made, as shown in Figure 1 and Figure 2 As shown, a fastening device 4 is arranged on the bottom surface of the indicating meter body 11. Specifically, the fastening device 4 comprises a connecting ball 41 arranged on the bottom surface of the indicating meter body 11 and a mounting bracket 42 rotationally connected to the connecting ball 41. The mounting bracket 42 acts as a support for installing the digital indicating meter 1 to the machine tool, and the mounting bracket 42 can be rotated around the connecting ball 41 to adjust the angle and position of the digital indicating meter 1, as shown in Figure 1 As shown, the mounting bracket 42 forms a through hole for installation, which facilitates quick installation. Further, the fastening device 4 further comprises a screwing member 43 arranged beside the through hole. The screwing member 43 can be screwed into the through hole, and quick screwing and fixing are performed during installation to prevent the digital indicating meter 1 from shaking during measurement, thereby improving the work efficiency.

[0032] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
