Description

Technical Field

[0001] The utility model relates to the technical field of thickness gauges, in particular to a portable thickness gauge for experiments. Background Art

[0002] A thickness gauge is an instrument used to measure the thickness of the material itself or the thickness of the coating on the surface of the material. The thickness of some components must be measured during manufacturing and maintenance in order to understand the thickness specifications of the material, the uniformity of each point, and the degree of corrosion and wear of the material; sometimes the thickness of the coating on the surface of the material must be measured to ensure product quality and production safety.

[0003] In physical laboratories, it is often necessary to measure the thickness of some samples. In order to avoid large data fluctuations caused by the compressibility of the sample or poor surface flatness, the thickness gauges used in physical laboratories usually use desktop thickness gauges. These gauges can apply a certain amount of pressure to the measuring surface of the sample while measuring the thickness. However, in order to ensure its stability, the base of this desktop thickness gauge is usually thick and heavy, which is not conducive to handheld measurement. In addition, the base occupies a large area, which is not conducive to carrying it. Therefore, a portable thickness gauge for experimental use is proposed. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a portable thickness gauge for experiments.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a portable thickness gauge for experimental use, comprising a handheld handle, a thickness measuring instrument, and a support base, wherein a circular hole is formed on one side of the handheld handle, and further comprising:

[0006] A splitting mechanism, which is provided on the supporting base and is used to separate the thickness gauge and the supporting base;

[0007] Among them, the splitting mechanism includes a card slot, which is opened at the top of the support base, and a cavity is opened in the middle of the support base. A first fixed shaft is fixed inside the cavity, and the outer surface of the first fixed shaft is sleeved with a movable frame and a first spring, and a limiting shaft is fixed on one side of the movable frame. A second fixed shaft is fixed inside the support base, and the outer surface of the second fixed shaft is sleeved with a second spring and an extrusion member, and a pressing plate is fixed on one side of the extrusion member.

[0008] As mentioned above, the first spring is elastically supported between the cavity and the movable frame.

[0009] As mentioned above, the end of the limiting shaft passes through the circular hole and is movably engaged with the circular hole, and the hand-held handle is sleeved with the card slot.

[0010] As mentioned above, the ends of the movable frame and the extrusion piece are both provided with chamfers, and the extrusion piece is in extrusion contact with the inclined surface of the movable frame.

[0011] As mentioned above, the second spring is elastically supported between the support base and the extrusion member.

[0012] As mentioned above, the pressing plate passes through the supporting base and is slidably connected to the supporting base. When the pressing plate presses the extrusion member, the limiting shaft can be separated from the circular hole.

[0013] Compared with the existing technology, this portable thickness gauge for experiment has the following beneficial effects:

[0014] 1. The utility model can drive the extrusion member to move along the outer surface of the second fixed shaft and squeeze the movable frame by pressing the pressing plate, thereby driving the movable frame to move along the outer surface of the first fixed shaft. At this time, the limit shaft will be separated from the circular hole and the limit on the handheld handle will be released. Then, the handheld handle and the card slot can be used to drive the thickness gauge to separate from the handheld handle, thereby facilitating handheld measurement or carrying of the thickness gauge.

[0015] 2. The utility model uses the elastic force of the second spring to make the extrusion piece have good elastic reset performance. At this time, since the second spring is in a compressed state, it will apply an elastic force to the extrusion piece, thereby driving the extrusion piece to release the extrusion of the movable frame, and then the elastic force of the first spring can drive the movable frame to reset, making it easy to assemble the hand grip and the support base, so that it can adapt to different places.

[0016] Other advantages, objectives and features of the present invention will be described in part in the following description and will be apparent to those skilled in the art based on an examination of the following or may be learned from the practice of the present invention.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, the utility model provides a portable thickness gauge for experiments, including a handheld handle 1, a thickness gauge 2 and a support base 3. A circular hole 4 is opened on one side of the handheld handle 1, and further includes:

[0025] A splitting mechanism, which is provided on the support base 3 and is used to separate the thickness measuring instrument 2 and the support base 3;

[0026] Among them, the splitting mechanism includes a slot 5, which is opened at the top of the support base 3, and a cavity 6 is opened in the middle of the support base 3. A first fixed shaft 7 is fixed inside the cavity 6, and the outer surface of the first fixed shaft 7 is sleeved with a movable frame 8 and a first spring 9. A limiting shaft 10 is fixed on one side of the movable frame 8, and a second fixed shaft 11 is fixed inside the support base 3. The outer surface of the second fixed shaft 11 is sleeved with a second spring 12 and an extrusion member 13, and a pressing plate 14 is fixed on one side of the extrusion member 13.

[0027] By pressing the pressing plate 14, the extrusion member 13 can be driven to move along the outer surface of the second fixed axis 11 and squeeze the movable frame 8, thereby driving the movable frame 8 to move along the outer surface of the first fixed axis 7. At this time, the limit axis 10 will be driven to separate from the circular hole 4 and the limit on the handheld handle 1 will be released. Then, through the cooperation between the handheld handle 1 and the card slot 5, the thickness gauge 2 can be driven to separate from the handheld handle 1, thereby facilitating handheld measurement or carrying of the thickness gauge 2.

[0028] like Figure 3 As shown, the first spring 9 is elastically supported between the cavity 6 and the movable frame 8 .

[0029] Through the design of the first spring 9, the movable frame 8 has good elastic reset performance. At this time, since the first spring 9 is in a compressed state, it will apply an elastic force to the movable frame 8, so that the handheld handle 1 can be limited by the cooperation between the limiting shaft 10 and the circular hole 4.

[0030] like Figure 2 、 3 As shown, the end of the limiting shaft 10 passes through the circular hole 4 and is movably engaged with the circular hole 4, and the handheld handle 1 is sleeved with the card slot 5.

[0031] Through the cooperation between the movable frame 8 and the first fixed shaft 7, the movable frame 8 can slide along the outer surface of the first fixed shaft 7. At this time, the hand-held handle 1 can be positioned through the cooperation between the limiting shaft 10 and the circular hole 4, and the cooperation between the hand-held handle 1 and the card slot 5.

[0032] like Figure 3 、 4 As shown in Figures 5 and 6, the ends of the movable frame 8 and the extrusion piece 13 are both provided with chamfers, and the extrusion piece 13 is in extrusion contact with the inclined surface of the movable frame 8.

[0033] Through the cooperation between the extrusion piece 13 and the movable frame 8, when the extrusion piece 13 squeezes the movable frame 8, it can drive the movable frame 8 to slide along the outer surface of the first fixed axis 7, thereby driving the limiting axis 10 to separate from the circular hole 4, thereby facilitating the disassembly of the handheld handle 1.

[0034] like Figure 5 As shown, the second spring 12 is elastically supported between the support base 3 and the extrusion member 13 .

[0035] Through the design of the second spring 12, the extrusion member 13 has good elastic reset performance. At this time, since the second spring 12 is in a compressed state, it will apply an elastic force to the extrusion member 13, thereby driving the extrusion member 13 to release the extrusion of the movable frame 8, and then the elastic force of the first spring 9 can drive the movable frame 8 to reset, making it easier to install the hand grip 1.

[0036] like Figure 3 、 4 As shown, the pressing plate 14 passes through the supporting base 3 and is slidably connected to the supporting base 3. When the pressing plate 14 presses the extruding member 13, the limiting shaft 10 can be separated from the circular hole 4.

[0037] Through the design of the pressing plate 14, the pressing plate 14 can be pressed from the outside of the handheld handle 1, thereby pushing the extrusion member 13 to move along the outer surface of the second fixed axis 11, causing the extrusion member 13 to squeeze the movable frame 8, and then driving the limit shaft 10 to separate from the circular hole 4.

[0038] Working principle:

[0039] When the thickness gauge 2 needs to be carried, the user can press the pressing plate 14 to drive the extrusion member 13 to move along the outer surface of the second fixed axis 11. When the extrusion member 13 moves, its inclined surface will be squeezed with the inclined surface of the movable frame 8. At this time, the movable frame 8 will move along the outer surface of the first fixed axis 7 and drive the limit shaft 10 to separate from the circular hole 4, so that the handheld handle 1 can be released from the limit. Then, through the cooperation between the handheld handle 1 and the card slot 5, the handheld handle 1 can be pulled apart from the card slot 5, so that the thickness gauge 2 can be used for handheld measurement.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
