Description

Thickness gauge

Technical Field

The invention relates to a thickness gauge, in particular to a thickness gauge capable of quickly measuring the gap size of an object.

Background

Various industrial products, such as circuit boards, mechanical parts or plastic finished products, may have holes, gaps and the like, and usually the holes and the gaps have specific dimensions, and at this time, the detailed dimensions of the holes and the gaps need to be measured by manually operating a thickness gauge, so as to judge whether the products meet the specifications.

However, the conventional thickness gauge has a disadvantage that when measuring the gap size of the product, a user needs to visually estimate the size of the gap first, and then select a feeler with a similar size from the thickness gauge and place the feeler into the gap to be measured. When the thickness of clearance gauge is too big, the clearance of product can't be put into to the clearance of clearance gauge, and when the thickness of clearance gauge is too little, clearance gauge and product clearance can have great cavity. Therefore, the user must try different thickness of the feeler step by step to find the feeler that can fit into the product gap, so as to measure the determined dimension of the gap. Because the conventional thickness gauge only depends on manpower to test the feelers with different thicknesses step by step, the measurement time is increased, and the working efficiency is low.

Disclosure of Invention

The invention provides a thickness gauge which is suitable for rapidly measuring the gap size of an object, and further achieves the purposes of shortening the measuring time and improving the working efficiency.

The thickness gauge is used for measuring the size of a gap of an object and comprises a base, an upper cover, an adjusting assembly and two measuring parts. The upper cover is arranged on the base and forms an accommodating space with the base, and the top surface of the upper cover is provided with a scale area. The adjusting component is movably arranged in the accommodating space along a moving direction and partially penetrates through the upper cover, and the width of the adjusting component is gradually reduced in the direction of moving out of the accommodating space. The two measuring pieces are movably arranged on the base and symmetrically positioned at two sides of the adjusting assembly so as to clamp the adjusting assembly in the adjusting assembly, and part of each measuring piece protrudes out of the upper cover and can move along the scale area. When the adjusting component moves along the moving direction to enable two sides of the adjusting component in the width direction to gradually approach to the two inner wall surfaces of the gap, the two measuring parts move oppositely along the scale area under the pushing of the adjusting component, and when the two sides of the adjusting component in the width direction touch the two inner wall surfaces of the gap, the two measuring parts indicate the width of the gap.

Based on the above, the thickness gauge of the present invention is suitable for measuring the size of the gap of an object, during the measurement process, the two measuring members of the thickness gauge penetrate into the gap of the object to be measured, and then the adjusting assembly drives the two measuring members to move along the scale area in opposite directions until the two measuring members respectively abut against the inner wall surface of the gap, and simultaneously the relative positions of the two measuring members on the scale area are checked to obtain the size value of the gap. The invention enables the two measuring parts to synchronously move towards each other by the adjusting component so as to be beneficial to measuring the clearance of an object, and can quickly obtain an exact size numerical value by the mark of the scale area.

Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1A is a schematic perspective view of a thickness gauge bearing object according to an embodiment of the invention. FIG. 1B is an exploded perspective view of the gauge of FIG. 1A.

Referring to fig. 1A and 1B, the thickness gauge 100 of the present embodiment is suitable for measuring the gap G of an object 200, and the thickness gauge 100 includes a base 110, an upper cover 120, an adjusting assembly 140 and two measuring members 130.

The base 110 has a U-shaped appearance and has two inner wall surfaces IS and a bottom surface BS. The upper cover 120 is disposed on the base 110 in a U-shape, and forms an accommodating space AS with the base 110, and the top surface TS of the upper cover 120 is provided with a scale area GA, wherein the scale area GA extends to two opposite outer edges of the upper cover 120, and the scale area GA is, for example, a metric unit or an english unit, which is not limited in the present invention.

The adjusting assembly 140 is movably disposed in the accommodating space AS along the moving direction D and partially penetrates through the upper cover 120, and the width W of the adjusting assembly 140 gradually decreases in a direction of moving out of the accommodating space.

The two measuring members 130 are movably disposed on the base 110 and symmetrically located at two sides of the adjusting assembly 140 to clamp the adjusting assembly 140 therein, and a portion of each measuring member 130 protrudes from the upper cover 120 and can move along the graduation area GA. In detail, the two measuring members 130 are disposed between the base 110 and the upper cover 120 and are symmetrical with respect to the adjusting assembly 140, the two measuring members 130 are suitable for moving toward each other along the calibration area GA, and the two measuring members 130 are used for inserting the gap G of the object 200, so as to facilitate measuring the size of the gap G. The adjusting assembly 140 is adapted to move relative to the base 110 and the cover 120 to drive the two measuring members 130 to move away from or close to each other.

When the adjusting member 140 moves along the moving direction D so that the two sides of the adjusting member 140 in the width W direction gradually approach the two inner wall surfaces IS of the gap G, the two measuring members 130 move toward each other along the scale area GA under the pushing of the adjusting member 140. When the adjustment member 140 touches the inner wall surfaces IS of the gap G on both sides in the width W direction, the measuring pieces 130 indicate the size of the gap G of the object 200.

Further, the moving direction D of the adjusting component 140 is perpendicular to the extending direction of the scale area GA.

Referring to fig. 1B, the present embodiment includes two elastic restoring elements 150, such as compression springs, respectively connected to the two measuring elements 130 and abutting against two opposite inner wall surfaces IS of the base 110. Further, the two elastic restoring members 150 are located on the bottom surface BS and parallel to the scale area GA.

When the adjusting assembly 140 moves toward the calibration area GA, the two measuring members 130 are pushed to move toward each other along the calibration area GA and respectively compress the two elastic restoring members 150, so that each elastic restoring member 150 accumulates an elastic force E. When the adjusting element 140 moves away from the calibration area GA, the two elastic restoring members 130 elastically restore and push the two adjusting elements 140 to approach each other along the calibration area GA by the two opposite elastic forces E.

FIG. 2A is a plan view of the thickness gauge of FIG. 1A in an initial state. FIG. 2B is a plan view of the thickness gauge of FIG. 1A in a measuring state. Referring to fig. 1A, fig. 1B and fig. 2A, each measuring member 130 includes a sliding block 131 and an indicating portion 132. The two sliding blocks 131 are symmetrically located at two sides of the adjusting assembly 140 and are respectively connected to the two elastic restoring members 150. Each of the indicating portions 132 is provided on the corresponding slider 131 and aligned with the scale area GA. In detail, each indication portion 132 is a hook structure and partially surrounds the upper cover 120 to be located in the calibration area GA.

Further, the base 110 has a first guide groove G1, and a recess is formed on the bottom surface BS. Each of the sliders 131 has a guiding portion GP, and the two guiding portions GP of the two sliders 131 are disposed in the first guiding groove G1, so that the two sliders 131 are adapted to move along the first guiding groove G1, thereby compressing or releasing the two elastic restoring members 150. The base 110 has two spaced racks 111 disposed on the bottom surface BS and parallel to the scale area GA and the first guide groove G1, and the two sliders 131 are slidably disposed on the two racks 111, respectively. The two sliding blocks 131 are adapted to slide along the two racks 111 synchronously, and each rack 111 is used to position the corresponding sliding block 131, so as to facilitate observation of the scale value of each indication portion 132 corresponding to the scale area GA.

Referring to fig. 1A, 1B and 2A, the adjusting assembly 140 includes a driving plate 141 and a toggle bar 142. The driving plate 141 is disposed on the bottom surface BS of the base 110 and has a driving end DE and a connecting end CE. Wherein the driving plate 141 is, for example, a triangular flat plate, i.e., the width W of the driving plate 141 is tapered from the connecting end CE toward the driving end DE to form two slopes IP. The entraining end DE of the entraining plate 141 is located between the two sliders 131 of the two measuring elements 130. The base 110 has a sliding rack 112 arranged at the center of the bottom surface BS of the base 110 and parallel to the moving direction D. The driving plate 141 has a slide rail toward the bottom BS for accommodating the sliding rack 112 of the base 110, and the driving plate 141 is adapted to move linearly along the sliding rack 112.

The tap lever 142 is disposed at the connection end CE and penetrates the upper cover 120. In detail, the upper cover 120 has a second guide groove G2 penetrating through the top surface of the upper cover 120. The tap lever 142 is located in the second guide groove G2 and adapted to linearly move along the second guide groove G2. Further, the adjusting assembly 140 includes two limiting blocks 143 disposed on opposite sides of the moving rod 142, and the two limiting blocks 143 abut against two inner wall surfaces of the second guiding groove G2, respectively, to limit the moving rod 142 and the driving plate 141. Since the limit block 143 is limited by the second guide groove G2, when the tap lever 142 moves in the second guide groove G2, it can only move linearly and cannot rotate, which is to prevent the deviation of the driving plate 141 from affecting the measurement of the gap G.

With reference to fig. 1A, 2A and 2B, the following describes the step of measuring the gap G of the object 200 by the thickness gauge 100. First, the object 200 is disposed on the top surface TS of the upper cover 120, and the two indicating portions 132 of the adjusting assembly 140 are accommodated with a gap G. At this time, the thickness gauge 100 is in an initial state, that is, the two sliding blocks 131 are pushed by the two elastic restoring members 150 to be relatively close to each other, and the two indicating portions 132 are respectively spaced from the two inner edges IE of the gap G.

Then, an external force is applied to the tap lever 142 to linearly move along the second guide groove G2 and toward the scale area GA, and the driving plate 141 moves relative to the base 110 along with the tap lever 142. The driving end DE of the driving plate 141 passes through the two sliding blocks 131, and synchronously pushes the two sliding blocks 131 left and right with the two inclined planes IP with gradually increasing width W and presses the two elastic restoring members 150 to accumulate the elastic force E, so that the two sliding blocks 131 are separated from each other along the first guide groove G1.

Meanwhile, the two sliding blocks 131 also drive the two indicating portions 132 to move away from each other along the scale area GA until the two indicating portions 132 abut against the two inner edges IE of the gap G, which indicates that the two indicating portions 132 have accurately measured the size of the gap G. At this time, the user can obtain the dimension value SD of the gap G by observing the scale positions of the two indicating portions 132 corresponding to the scale area GA.

After the size of the gap G is measured, the user only needs to release the external force applied to the dial bar 142, and the two elastic restoring members 150 release the two opposite elastic forces E at the same time, so that the two sliders 131 are relatively close to each other along the first guide groove G1 and simultaneously push the two inclined planes IP of the driving plate 141, so that the driving plate 141 and the dial bar 142 linearly move along the second guide groove G2 and are far away from the scale area GA, and finally the thickness gauge 100 is restored to the initial state.

Referring to fig. 2A and fig. 3, the thickness gauge 100A of the present embodiment is similar to the thickness gauge 100 of fig. 2A. The difference is that the thickness gauge 100A uses another driving plate 141a, and the angle a between the two inclined surfaces IP of the driving plate 141 is larger than the angle a between the two inclined surfaces IP of the driving plate 141, so that the width W of the driving plate 141a is larger than the width W of the driving plate 141. Therefore, when the driving plate 141a is used, the maximum distance between the two sliders 131 can be increased, which is advantageous for measuring the object 200 having the large size of the gap G. Furthermore, the thickness gauge can replace the driving plate with the corresponding included angle according to the gaps of the objects to be measured with different sizes, so as to achieve the effect of rapid measurement.

The thickness gauge of the preferred embodiment of the invention is suitable for measuring the size of the gap of an object, in the measuring process, two measuring parts of the thickness gauge penetrate into the gap of the object to be measured, then the adjusting assembly drives the two measuring parts to move oppositely along the scale area until the two measuring parts respectively abut against the inner wall surface of the gap, and meanwhile, the relative positions of the two measuring parts on the scale area are checked to obtain the size value of the gap. The invention enables the two measuring parts to synchronously move towards each other by the adjusting assembly so as to be beneficial to measuring the gap of an object, and can quickly acquire an exact size numerical value by the mark of the scale area.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
