Description

Technical Field

[0001] This invention relates to the field of teaching equipment technology, specifically to a gap inspection teaching device. Background Technology

[0002] Vehicle hoses are components of automotive braking systems. During the manufacturing process of vehicle hoses, the hose gaps are inspected to maintain their quality. However, due to the variety of vehicle hose types, training tools are needed to ensure that workers clearly understand the hose gap inspection process. Current techniques typically involve attaching a connecting component to the hose and then measuring the gap between one end of the hose and the connecting component. However, this demonstration is flawed because the connecting component is fixed and cannot be adjusted, and the distance between the connecting component and the hose end cannot be displayed in real time. Therefore, the gap between the hose and the connecting component cannot be readily determined, resulting in a less clear and intuitive demonstration.

[0003] Therefore, it is necessary to provide a gap inspection teaching device to solve the above-mentioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide a gap inspection teaching device, which aims to solve the technical problem of poor teaching effect in the prior art regarding gap inspection.

The first protrusion is connected to the first mounting plate, and the second protrusion is connected to the second mounting plate. One end of the first threaded rod passes through the first protrusion and the first mounting plate and is connected to one of the operating handles. The other end of the first threaded rod passes through the second protrusion and is connected to the second mounting plate. One end of the second threaded rod passes through the first protrusion and the first mounting plate and is connected to the other operating handle. The other end of the second threaded rod passes through the second protrusion and is connected to the second mounting plate.

[0012] In one embodiment, the base assembly further includes a protective component, which includes a back plate, a shield, and two side plates respectively disposed on both sides of the back plate. The first mounting plate has a first notch, and the second mounting plate has a second notch. The two ends of the back plate are respectively engaged with the first notch and the second notch. The measuring instrument is mounted on the back plate. One end of the shield is rotatably mounted on one of the side plates, and the other end of the shield can abut against the other side plate.

[0013] In one embodiment, the base assembly further includes an operating platform, the operating platform further includes a base and a plurality of wheels, the first mounting plate and the second mounting plate are mounted on the top of the base, and the plurality of wheels are evenly mounted on the bottom of the base.

[0014] In one embodiment, the base assembly further includes a parking component, which includes a support plate and a threaded sub-component. The support plate is connected to the base, and the support plate is provided with a first threaded hole. The threaded sub-component is telescopically installed in the first threaded hole, and the bottom of the threaded sub-component can be used to abut against the ground.

[0015] In one embodiment, the threaded sub-component includes an anti-slip pad and a third threaded rod. The anti-slip pad is provided with a second threaded hole, and the third threaded rod is threadedly connected to the second threaded hole. The side of the anti-slip pad away from the third threaded rod is used to abut against the ground.

[0016] In the above scheme, the gap inspection teaching device includes a base assembly, a measuring assembly, and a fixing assembly. The fixing assembly includes a fixing component and a measuring hose. The fixing component is installed on the base assembly, and the measuring hose is sleeved on the fixing component. The measuring assembly includes a first connecting component, a second connecting component, a sliding component, a first slider, a second slider, and two measuring instruments. The sliding component is installed on the base assembly, and both the first slider and the second slider are slidably installed on the sliding component. The two measuring instruments are installed on the base assembly at intervals. The first connecting component includes a first top, a first bottom, and a first middle portion located between the first top and the first bottom.

[0017] Specifically, before starting the lesson, the instructor first places the measuring hose on the fixed component, then slides the top of the first connecting component onto the fixed component, and places the second connecting component on the measuring hose. When the lesson begins, the instructor first slides the first slider on the sliding component. Since the first connecting component is connected to the first slider, as the first slider moves, the first connecting component moves along the length of the fixed component until it abuts against the end face of the measuring hose, and the bottom of the first connecting component abuts against a measuring gauge. At this point, the reading on this measuring gauge can be read. Then, the second slider slides on the sliding component. Since the second connecting component is connected to the second slider, as the second slider moves, the second connecting component moves along the length of the measuring hose to a certain position, and the bottom of the second connecting component abuts against another measuring gauge. The reading on this measuring gauge can then be read. Subtracting these two readings allows for the simulation of the gap between the hose and other vehicle components. With this structural setup, the learner can clearly learn the measurement method and see the measurement data in real time, thus improving the effectiveness and quality of the lesson.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each workpiece in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0033] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0036] To achieve the above objectives, the present invention provides a gap inspection teaching device 100, see [link to documentation]. Figures 1 to 3 The gap inspection teaching device 100 includes a base assembly 1, a measuring assembly 2 and a fixing assembly 3. The fixing assembly 3 includes a fixing component 31 and a measuring hose 32. The fixing component 31 is installed on the base assembly 1 and the measuring hose 32 is sleeved on the fixing component 31.

[0037] The measuring component 2 includes a first connecting component 21, a second connecting component 22, a sliding component 23, a first slider 24, a second slider 25, and two measuring instruments 26. The sliding component 23 is mounted on the base component 1. The first slider 24 and the second slider 25 are both slidably mounted on the sliding component 23. The two measuring instruments 26 are mounted on the base component 1 at intervals. The first connecting component 21 includes a first top 211, a first bottom 212, and a first middle portion 213 located between the first top 211 and the first bottom 212. The first middle portion 213 is mounted on the first slider 24. The first top 211 is slidably sleeved on the fixing component 31. The first bottom 212 can abut against one measuring instrument 26. The second connecting component 22 includes a second top 221, a second bottom 222, and a second middle portion 223 located between the second top 221 and the second bottom 222. The second middle portion 223 is mounted on the second slider 25. The second top 221 is slidably sleeved on the measuring hose 32. The second bottom 222 can abut against the other measuring instrument 26. Specifically, before starting the lesson, the instructor first places the measuring hose 32 onto the fixed component 31, then slides the top of the first connecting component 21 onto the fixed component 31, and places the second connecting component 22 onto the measuring hose 32. When starting the lesson, the instructor first slides the first slider 24 on the sliding component 23. Since the first connecting component 21 is connected to the first slider 24, when the first slider 24 moves, the first connecting component 21 will move along the length of the fixed component 31 until it abuts against the end face of the measuring hose 32. The bottom of the measuring hose 32 abuts against a measuring gauge 26, allowing the reading on this gauge 26 to be taken. Then, the second slider 25 slides on the sliding member 23. Since the second connecting member 22 is connected to the second slider 25, as the second slider 25 moves, the second connecting member 22 moves along the length of the measuring hose 32 to a certain position, and the bottom of the second connecting member 22 abuts against another measuring gauge 26, allowing the reading on this gauge 26 to be taken. Subtracting these two readings allows for the simulation of the gap between the hose and other vehicle components. This structural design allows learners to clearly understand the measurement method and see the measurement data in real time, improving the effectiveness and quality of teaching.

[0038] See Figures 1 to 3 In one embodiment, the first connecting component 21 includes a first sleeve 211a and a first long plate 212b, with a first top 211 disposed on the first sleeve 211a and a first bottom 212 disposed on the bottom of the first long plate 212b. The second connecting component 22 includes a second sleeve 221a and a second long plate 222b, with a second top 221 disposed on the second sleeve 221a and a second bottom 222 disposed on the bottom of the second long plate 222b. The second sleeve 221a is sleeved on the measuring hose 32.

[0039] See Figure 1 and Figure 4 In one embodiment, the sliding component 23 includes a fixed base 231, a first threaded rod 232, and a second threaded rod 233. The fixed base 231 has a groove 231a and a first protrusion 231b and a second protrusion 231c disposed on both sides of the groove 231a. The two ends of the first threaded rod 232 pass through the first protrusion 231b and the second protrusion 231c respectively and are connected to the base assembly 1. The two ends of the second threaded rod 233 pass through the first protrusion 231b and the second protrusion 231c respectively and are connected to the base assembly 1. The first threaded rod 232 and the second threaded rod 233 have a distance difference in the vertical direction. The first slider 24 is threadedly connected to the first threaded rod 232, and the second slider 25 is threadedly connected to the second threaded rod 233. Specifically, since the first slider 24 is threadedly connected to the middle of the first threaded rod 232, when the first threaded rod 232 is rotated, the first slider 24 will move along the length of the first threaded rod 232. This will drive the first connecting component 21 to move in the same direction until it abuts against the end face of the measuring hose 32, and the bottom of the first connecting component 21 abuts against a measuring gauge 26. At this point, the reading on the measuring gauge 26 can be read. Since the second slider 25 is threadedly connected to the middle of the second threaded rod 233, when the second threaded rod 233 is rotated, the second slider 25 will move along the length of the second threaded rod 233. This will drive the second connecting component 22 to move in the same direction. After moving a certain distance, the bottom of the second connecting component 22 abuts against another measuring gauge 26. At this point, the reading on the measuring gauge 26 can be read. Subtracting these two readings will simulate the gap between the hose and other vehicle components. Driving the first connecting component 21 and the second connecting component 22 by means of threaded rods is a simple and convenient control method.

[0040] See Figure 1 , Figure 2 and Figure 4 Furthermore, the first slider 24 is provided with a first limiting hole, the second slider 25 is provided with a second limiting hole, and the fixed base 231 is provided with multiple third limiting holes 231d. The third limiting holes 231d are located between the first protrusion 231b and the second protrusion 231c. The gap inspection teaching device 100 also includes limiting members 4, with at least two limiting members 4. When the first slider 24 and the second slider 25 have both moved to the appropriate positions, one limiting member 4 passes through the first limiting hole and is installed in a third mounting hole, and the other limiting member 4 passes through the second limiting hole and is installed in another third mounting hole. This can prevent the numerical changes caused by accidentally touching the first slider 24 or the second slider 25 during the data viewing process, and can ensure the accuracy of the measurement data.

[0041] See Figure 1 , Figure 2 and Figure 4 In one embodiment, the sliding component 23 further includes a guide rod 234, with its two ends connected to a first protrusion 231b and a second protrusion 231c, respectively. The first slider 24 has a first through hole 231f, and the second slider 25 has a second through hole 231g. The first slider 24 is slidably fitted onto the guide rod 234 through the first through hole 231f, and the second slider 25 is slidably fitted onto the guide rod 234 through the second through hole 231g. By providing the guide rod 234, it is ensured that the first slider 24 and the second slider 25 can move in a straight line, preventing deviations during sliding and thus measurement errors.

[0042] See Figure 1 and Figure 7 In one embodiment, a scale 231e is provided on the top of the fixing base 231. Specifically, since the first slider 24 is threadedly connected to the middle of the first threaded rod 232, when the first threaded rod 232 is rotated, the first slider 24 will move along the length of the first threaded rod 232, thus driving the first connecting component 21 to move in the same direction until it abuts against the end face of the measuring hose 32. At this time, the instructor can read the reading of the first connecting component 21 from the scale 231e on the top of the fixed base 231. Since the second slider 25 is threadedly connected to the middle of the second threaded rod 233, when the second threaded rod 233 is rotated, the second slider 25 will move along the length of the second threaded rod 233, thus driving the second connecting component 22 to move in the same direction. After moving a certain distance, the instructor can read the reading of the second connecting component 22 from the scale 231e on the top of the fixed base 231. Then, the two readings are subtracted to obtain the gap data, which is then compared with the data calculated by the measuring instrument 26. This reminds the student to ensure the accuracy of the measurement in subsequent work.

[0043] See Figure 1 and Figure 3In one embodiment, the base assembly 1 includes a first mounting plate 11 and a second mounting plate 12. The sliding component 23 also includes an operating handle 235. There are two operating handles 235. A first protrusion 231b is connected to the first mounting plate 11, and a second protrusion 231c is connected to the second mounting plate 12. One end of a first threaded rod 232 passes through the first protrusion 231b and the first mounting plate 11 and is connected to one operating handle 235. The other end of the first threaded rod 232 passes through the second protrusion 231c and is connected to the second mounting plate 12. One end of a second threaded rod 233 passes through the first protrusion 231b and the first mounting plate 11 and is connected to the other operating handle 235. The other end of the second threaded rod 233 passes through the second protrusion 231c and is connected to the second mounting plate 12. The instructor can rotate the first threaded rod 232 and the second threaded rod 233 by operating the two handles 235 respectively. After the first threaded rod 232 and the second threaded rod 233 are rotated, the first slider 24 and the second slider 25 can be moved. This can further improve the instructor's ease of operation and protect the instructor from being cut by the threads on the first threaded rod 232 and the second threaded rod 233.

[0044] See Figure 5 Furthermore, the base assembly 1 also includes a first welding plate 111 welded to the first mounting plate 11 and a second welding plate 121 welded to the second mounting plate 12. A first protrusion 231b is mounted on the first welding plate 111 and a second protrusion 231c is mounted on the second welding plate 121. The first welding plate 111 and the second welding plate 121 serve to connect the sliding component 23.

[0045] See Figure 1 , Figure 5 , Figure 6 and Figure 7 Furthermore, the gap inspection teaching device 100 also includes two limit nuts 5 and two limit bolts 6. One limit bolt 6 is installed at one end through the first mounting plate 11 and attached to one end of the fixing component 31, and one limit nut 5 is installed at the other end of one limit bolt 6 and abuts against the first mounting plate 11. The other limit bolt 6 is installed at one end through the second mounting plate 12 and attached to the other end of the fixing component 31, and another limit nut 5 is installed at the other end of the other limit bolt 6 and abuts against the second mounting plate 12. This makes the disassembly and installation of the fixing component 31 more convenient.

[0046] See Figure 5In one embodiment, the base assembly 1 further includes a protective component 13, which includes a back plate 131, a shielding plate 132, and two side plates 133 respectively disposed on both sides of the back plate 131. The first mounting plate 11 is provided with a first notch 112, and the second mounting plate 12 is provided with a second notch 122. The two ends of the back plate 131 are respectively engaged with the first notch 112 and the second notch 122. The measuring instrument 26 is mounted on the back plate 131. One end of the shielding plate 132 is rotatably mounted on one side plate 133, and the other end of the shielding plate 132 can abut against the other side plate 133. Specifically, during operation, the shield 132 is rotated around the side plate 133, and then the other end of the shield 132 abuts against the other side plate 133. This can shield the internal components and protect them from being damaged by external objects. After the operation is completed, the shield 132 is rotated in the opposite direction so that the other side of the shield 132 moves away from the other side plate 133. In this way, the instructor can read the data from the measuring instrument 26 and thus determine the gap distance between the hose and the other parts of the car. By setting such a structure, the internal structure of the gap inspection teaching device 100 can be protected from damage.

[0047] See Figure 5 and Figure 7 In one embodiment, the protective component 13 further includes a hinge rod 134. A first hinge sleeve 133a is provided on the side of one side plate 133 away from the back plate 131. The shielding plate 132 is provided with two spaced-apart second hinge sleeves 132a. The first hinge sleeve 133a is rotatably sleeved on the middle of the hinge rod 134, and the two second hinge sleeves 132a are respectively rotatably sleeved on both ends of the hinge rod 134. Specifically, during rotation, the second hinge sleeves 132a only need to rotate around the hinge rod 134 to achieve the shielding effect. The hinge-type connection method has a greater load-bearing capacity, is flexible in use, and is sturdy and durable.

[0048] See Figure 8 In one embodiment, the base assembly 1 further includes an operating platform 14, which includes a base 142 and a plurality of wheels 141. A first mounting plate 11 and a second mounting plate 12 are mounted on the top of the base 142, and the plurality of wheels 141 are evenly mounted on the bottom of the base 142. By providing the wheels 141, the device can be moved to any position, facilitating the movement of the device.

[0049] See Figure 1 , Figure 3 and Figure 6Furthermore, the base 142 includes a flat plate 142a, on which a plurality of first mounting holes 142b are provided, the plurality of first mounting holes 142b being evenly distributed. A second mounting hole is provided on the first mounting plate 11, and a third mounting hole is provided on the second mounting plate 12. The base assembly 1 also includes fasteners 17, the number of which is at least two. One fastener 17 passes through the second mounting hole and is installed in one of the first mounting holes 142b, and the other fastener 17 passes through the third mounting hole and is installed in another of the first mounting holes 142b. This can more firmly fix the first mounting plate 11 and the second mounting plate 12.

[0050] See Figure 1 , Figure 3 and Figure 6 Furthermore, the operating table 14 also includes an extension plate 143, which is vertically mounted on the flat plate 142a. The extension plate 143 is provided with a plurality of fourth mounting holes 143a. The first protrusion 231b is provided with a first through hole 231f, and the second protrusion 231c is provided with a second through hole 231g. The base assembly 1 also includes locking members 15. The number of locking members 15 is at least two. One locking member 15 passes through the first through hole 231f and is mounted on one of the fourth mounting holes 143a, and the other locking member 15 passes through the second through hole 231g and is mounted on another of the fourth mounting holes 143a. This can fix the first protrusion 231b and the second protrusion 231c. When the first slider 24 and the second slider 25 slide, the first protrusion 231b and the second protrusion 231c will not move, thus ensuring the accuracy of the measurement results.

[0051] See Figure 1 , Figure 3 and Figure 6 Furthermore, the first mounting hole 142b can be used to hang teaching aids and teaching pipes.

[0052] See Figure 1 , Figure 3 and Figure 6 Furthermore, the base 142 also includes partitions 142c spaced apart in the vertical direction, on which personal items can be placed.

[0053] See Figure 1 , Figure 3 , Figure 6 and Figure 8In one embodiment, the base assembly 1 further includes a parking component 16, which includes a support plate 161 and a threaded sub-component 162. The support plate 161 is connected to the base 142 and has a first threaded hole. The threaded sub-component 162 is telescopically installed in the first threaded hole, and its bottom can be used to abut against the ground. When the gap inspection teaching device 100 moves to a suitable position, the threaded sub-component 162 is rotated so that it extends towards the ground until the distance of its extension is greater than the diameter of the wheel 141, thus preventing the gap inspection teaching device 100 from moving further. When movement is required, the threaded sub-component 162 is rotated so that it retracts to a length less than the diameter of the wheel 141, allowing the wheel 141 to move the gap inspection teaching device 100. This structure prevents the gap inspection teaching device 100 from moving during measurement, thus avoiding inaccurate measurement results.

[0054] See Figure 1 , Figure 3 , Figure 6 and Figure 8 In one embodiment, the threaded sub-component 162 includes an anti-slip pad 162a and a third threaded rod 162b. The anti-slip pad 162a has a second threaded hole, and the third threaded rod 162b is threadedly connected to the second threaded hole. The side of the anti-slip pad 162a away from the third threaded rod 162b is used to abut against the ground. The third threaded rod 162b is in direct contact with the ground, and will wear down over time, causing its length to shorten and preventing it from functioning as a parking device. The anti-slip pad 162a protects the third threaded rod 162b from wear.
