Description

Technical Field

[0001] This utility model relates to the technical field of instrument cases, and in particular to a novel engineering testing instrument case based on a multi-protection structure. Background Technology

[0002] An instrument case is a box specifically designed for the safe storage and transport of various measuring instruments and their accessories. They typically feature a robust construction to protect the internal equipment from damage. Made of waterproof and shockproof materials, instrument cases enhance their durability and versatility, making them suitable for various working environments.

[0003] In the existing technology, the equipment used for testing the physical protection system of nuclear facilities includes instruments such as illuminometers, handheld laser rangefinders, and field strength meters. When storing field strength meters, it is necessary not only to avoid collision damage, but also to provide insulation to prevent excessively high or low temperatures from increasing reading errors and affecting the test. While instrument cases usually provide strong protection for limiting and buffering, they are relatively weak in terms of temperature protection, making the protective effect of the instrument cases on the equipment used for testing the physical protection system of nuclear facilities poor. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of engineering inspection instrument box based on a multi-protection structure, so as to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A novel engineering inspection instrument case based on a multi-protection structure includes a case body, which is mainly composed of an upper cover and a lower cover. The top of the lower cover has a track groove, and the upper cover is hinged to one side of the top of the lower cover.

[0007] The cushioning airbag, which is located inside the enclosure, is used to provide cushioning for the instrument;

[0008] The booster unit is located inside the lower cover and includes a screw, a slider, a sleeve, a crankshaft, and a piston. The screw is rotatably connected to the track groove, and the slider is slidably connected to the outer wall of the screw. The slider is connected to the spiral groove of the screw through ball bearings. A sleeve is embedded in the lower cover near the track groove. The end of the sleeve communicates with the buffer airbag, and a one-way valve is provided at the communication position. A piston is slidably connected inside the sleeve. The end of the screw is inserted into the sleeve and fixedly connected to the crankshaft. The crankshaft and the piston are connected by a connecting rod.

[0009] Furthermore, the outer diameter of the piston is smaller than the inner diameter of the sleeve, so that there is a space between the outer wall of the piston and the inner wall of the sleeve for air intake. A rubber sheet is fixedly connected to the end of the piston away from the connecting rod, and the edge of the rubber sheet is connected to the inner wall of the sleeve.

[0010] Furthermore, the buffer airbag includes an upper airbag and a lower airbag, which are respectively connected to the inner walls of the upper and lower lids. The upper and lower airbags are connected by a connecting pipe on the side near the hinge position of the upper and lower lids.

[0011] Furthermore, the top of the lower cover is provided with an air passage communicating with the lower airbag, and a pressure relief valve is fixedly connected to the opening of the air passage, and a pressure-sensitive switch is fixedly connected to the top of the pressure relief valve.

[0012] Furthermore, a support rod is rotatably connected to the top of the slider, and the end of the support rod away from the slider is rotatably connected to the bottom of the upper cover.

[0013] Furthermore, both the upper and lower box covers are equipped with flexible fillers, and the surfaces of the flexible fillers are machined with multiple crisscrossing cuts.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. This novel engineering inspection instrument case based on a multi-protection structure, through the inclusion of buffer airbags, provides better protection for the instrument case while the air filling within the buffer airbags further prevents heat exchange. At the same time, the excellent thermal insulation performance of the rubber material of the buffer airbags reduces the temperature interference of the external environment on the instruments inside the case, thereby effectively improving the heat preservation effect of the instrument case and thus making the instrument case more effective in protecting the equipment of the nuclear facility physical protection system inspection.

[0016] 2. This novel engineering testing instrument case based on a multi-protection structure, through a pressurization unit, can inflate the buffer airbags, increasing the pressure applied by the buffer airbags to the flexible filler. This improves the fit between the flexible filler and the instrument, further enhancing the instrument's stability. Simultaneously, the inflated buffer airbags cause the edges of the upper and lower airbags to bulge. When the upper and lower covers are closed, the bulging parts of the upper and lower airbags will abut against each other, resulting in a tight seal between the upper and lower airbags. This improves the sealing performance of the instrument case, enhancing its waterproof effect and further improving its practicality. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1 - Figure 5 The present invention discloses a novel engineering inspection instrument box based on a multi-protection structure, which includes a box body 1. The box body 1 is mainly composed of an upper box cover 101 and a lower box cover 102. The top of the lower box cover 102 is provided with a track groove 4, and the upper box cover 101 is hinged to one side of the top of the lower box cover 102.

[0027] The buffer airbag 2 is installed inside the housing 1 to provide cushioning for the instrument;

[0028] The booster unit 3 is located inside the lower cover 102. The booster unit 3 includes a screw 301, a slider 302, a sleeve 303, a crankshaft 304, and a piston 305. The screw 301 is rotatably connected to the track groove 4. The slider 302 is slidably connected to the outer wall of the screw 301. The slider 302 is connected to the spiral groove of the screw 301 through a ball bearing 5. The sleeve 303 is embedded in the lower cover 102 near the track groove 4. The end of the sleeve 303 is connected to the buffer airbag 2, and a one-way valve 6 is provided at the connection position. The piston 305 is slidably connected inside the sleeve 303. The end of the screw 301 is inserted into the sleeve 303 and fixedly connected to the crankshaft 304. The crankshaft 304 and the piston 305 are connected by a connecting rod 7.

[0029] In this embodiment, observation Figure 1 It can be seen that by setting up a box 1, the box 1 is mainly composed of an upper box cover 101 and a lower box cover 102. The upper box cover 101 is hinged to the top side of the lower box cover 102, so that when the upper box cover 101 and the lower box cover 102 are closed, a space for storing instruments is formed between the upper box cover 101 and the lower box cover 102.

[0030] Because the instruments need to be stored with restraints to prevent damage from shaking or collisions, observation... Figure 1 It can also be observed that flexible padding 13 is provided inside both the upper cover 101 and the lower cover 102. The flexible padding 13 is made of flexible materials such as sponge and foam, which can effectively provide cushioning for the instrument and enhance its protective performance. Further observation... Figure 1 It can be observed that the surface of the flexible filler 13 has multiple intersecting cuts 14, which makes the instrument box more flexible during use. Figure 2 As shown in the diagram, the foam of the flexible filling 13 is folded down according to the shape of the instrument, allowing the instrument's limiting groove to be freely set inside the flexible filling 13. This can effectively improve the applicability of the instrument case and further enhance its practicality.

[0031] GB50348, as a mandatory national standard for the security industry, includes basic requirements for the security industry. The dedicated engineering inspection instruments and equipment mainly include resolution test cards, grayscale test cards, digital grounding resistance testers, pointer-type tensile testers, illuminance meters, handheld laser rangefinders, field strength meters, sound level meters, thermo-hygrometers, personal radiation meters, steel tape measures, and network analyzers. Among them, field strength meters have requirements for the storage environment, and extreme high and low temperature environments such as summer and winter need to be avoided. Therefore, a special toolbox was designed based on the equipment for inspecting the physical protection system of nuclear facilities.

[0032] Observe at this time Figure 1It can be observed that a buffer airbag 2 is installed inside the housing 1, and the buffer airbag 2 is mainly composed of an upper airbag 201 and a lower airbag 202. The upper airbag 201 and the lower airbag 202 are respectively connected to the inner walls of the upper housing cover 101 and the lower housing cover 102. The side of the upper airbag 201 and the lower airbag 202 near the hinge position of the upper housing cover 101 and the lower housing cover 102 is connected by a connecting pipe 203. The buffer airbag 2 can provide better protection for the instrument housing, and the air filling in the buffer airbag 2 can further avoid heat exchange of the air. At the same time, the excellent heat insulation performance of the rubber material of the buffer airbag 2 reduces the temperature interference of the external environment on the instruments inside the instrument housing, thereby effectively improving the heat preservation effect of the instrument housing, and thus making the instrument housing better protect the equipment of the nuclear facility physical protection system inspection.

[0033] Subsequently combined Figure 1 and Figure 2 It can be observed that a pressurizing unit 3 is installed inside the lower cover 102. The pressurizing unit 3 includes a screw 301, a slider 302, a sleeve 303, a crankshaft 304, and a piston 305. A track groove 4 is provided on the top of the lower cover 102, allowing the screw 301 to be rotatably connected within the track groove 4. The slider 302 is slidably connected to the outer wall of the screw 301. Simultaneously, to allow the screw 301 to rotate when the slider 302 slides, observation... Figure 3 It can be seen that the slider 302 is connected to the spiral groove of the screw 301 through the ball 5, which can effectively improve the sliding stability of the slider 302.

[0034] Now let's look at it again. Figure 2 It can be observed that a sleeve 303 is embedded in the lower cover 102 near the track groove 4, at which point it is combined with... Figure 4 As can be seen, the end of the sleeve 303 is connected to the buffer airbag 2, and a one-way valve 6 is provided at the connection position. The piston 305 is slidably connected inside the sleeve 303. The end of the screw 301 is inserted into the sleeve 303 and fixedly connected to the crankshaft 304. The crankshaft 304 and the piston 305 are connected by a connecting rod 7. When the slider 302 slides in the track groove 4, the screw 301 will rotate, thereby rotating the crankshaft 304. The connecting rod 7 pushes the piston 305 to slide back and forth in the sleeve 303.

[0035] And in Figure 4We can see that the outer diameter of piston 305 is smaller than the inner diameter of sleeve 303, leaving a space between the outer wall of piston 305 and the inner wall of sleeve 303 for air intake. A rubber sheet 8 is fixedly connected to the end of piston 305 away from connecting rod 7, and the edge of the rubber sheet 8 is connected to the inner wall of sleeve 303. When piston 305 moves away from buffer airbag 2, the rubber sheet 8 rubs against the inner wall of sleeve 303. Since the side of rubber sheet 8 away from piston 305 is unsupported, it deforms, creating a gap that allows air to enter piston 305. Between 05 and the one-way valve 6, when the piston 305 is reset, the piston 305 provides support to the rubber sheet 8, affecting the deformation of the rubber sheet 8 and reducing the deformation amplitude of the rubber sheet 8. At this time, the rubber sheet 8 cannot generate enough gap for air leakage, so that the air passes through the one-way valve 6 and is forced into the buffer airbag 2, thereby inflating the buffer airbag 2. This can be used to increase the pressure applied by the buffer airbag 2 to the flexible filler 13, thereby improving the fit between the flexible filler 13 and the instrument, and further improving the fixation stability of the instrument.

[0036] At the same time, the inflated buffer airbag 2 will cause the edges of the upper airbag 201 and the lower airbag 202 to bulge. When the upper cover 101 and the lower cover 102 are closed, the bulging parts of the upper airbag 201 and the lower airbag 202 will abut against each other, so that the contact points between the upper airbag 201 and the lower airbag 202 are tightly fitted, which can improve the sealing performance inside the instrument case, thereby improving the waterproof effect of the instrument case and further enhancing the practicality of the instrument case.

[0037] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the top of the lower cover 102 is provided with an air passage 9 that communicates with the lower airbag 202. A pressure relief valve 10 is fixedly connected to the opening of the air passage 9, and a pressure relief valve 11 is fixedly connected to the top of the pressure relief valve 10.

[0038] In this embodiment, the expansion of the buffer airbag 2 will increase the limiting force of the flexible filling 13 on the instrument, thereby increasing the friction when the instrument is removed and making it more difficult to remove the instrument.

[0039] Therefore, observe Figure 5 It can be observed that the top of the lower cover 102 has an air passage 9 that communicates with the lower airbag 202. A pressure relief valve 10 is fixedly connected to the opening of the air passage 9, and a pressure-sensitive switch 11 is fixedly connected to the top of the pressure relief valve 10. When the instrument needs to be removed, the pressure relief valve 10 can be opened by pressing the pressure-sensitive switch 11, thereby allowing the air in the buffer airbag 2 to be discharged through the air passage 9. This can reduce the pressure exerted by the buffer airbag 2 on the flexible filling 13, thereby reducing the difficulty of removing the instrument.

[0040] In a further preferred embodiment of this utility model, such as Figure 1- Figure 3 As shown, a support rod 12 is rotatably connected to the top of the slider 302, and the end of the support rod 12 away from the slider 302 is rotatably connected to the bottom of the upper box cover 101.

[0041] In this embodiment, a support rod 12 is rotatably connected to the top of the slider 302. The end of the support rod 12 away from the slider 302 is rotatably connected to the bottom of the upper cover 101. When the instrument case is opened, the support rod 12 can pull the slider 302 to the end of the track groove 4. Then, when the instrument case is closed, the support rod 12 will push the slider 302 to reset, causing the screw 301 to rotate, thereby inflating the buffer airbag 2 and making the use of the instrument case more stable.

[0042] The implementation principle of the above embodiment is as follows: Open the instrument case, place the equipment for testing the physical protection system of nuclear facilities on the flexible filler 13, and then cut out the corresponding placement slot according to the size of the instrument so that the equipment for testing the physical protection system of nuclear facilities can be placed in the instrument case.

[0043] After the instrument is placed, as the upper cover 101 and the lower cover 102 are closed, the support rod 12 will push the slider 302 to move in the track groove 4, thereby causing the screw 301 to rotate. At this time, the crankshaft 304 will drive the piston 305 to reciprocate to inflate the buffer airbag 2, which can be used to increase the pressure applied by the buffer airbag 2 to the flexible filler 13, thereby improving the adhesion between the flexible filler 13 and the instrument, and further improving the fixed stability of the instrument.

[0044] At the same time, the inflated buffer airbag 2 will cause the edges of the upper airbag 201 and the lower airbag 202 to bulge. When the upper cover 101 and the lower cover 102 are closed, the bulging parts of the upper airbag 201 and the lower airbag 202 will abut against each other, so that the contact points between the upper airbag 201 and the lower airbag 202 are tightly fitted, which can improve the sealing performance inside the instrument case, thereby improving the waterproof effect of the instrument case and further enhancing the practicality of the instrument case.

[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
