Description

Technical Field

[0001] This utility model relates to the field of instrumentation technology, specifically a high-precision instrumentation protective housing. Background Technology

[0002] With the development of industrial automation, various high-precision instruments and meters are being applied in various fields. Instruments and meters are tools or equipment used to detect, measure, observe, and calculate various physical quantities, material composition, physical property parameters, etc. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, multipliers, etc. all belong to instruments and meters. In a broader sense, instruments and meters can also have functions such as automatic control, alarm, signal transmission, and data processing.

[0003] As precision devices, instruments and meters require careful protection during transportation and handling. Without protection, damage is highly likely, especially to the instrument's screen, which not only affects its appearance but also its reading function. Existing protective housings offer limited impact resistance and protection for instruments and meters. Furthermore, in practical use, instruments come in various shapes, including rectangular and circular ones, and existing devices are only suitable for instruments of a single shape, lacking versatility. Therefore, we have designed a high-precision protective housing for instruments and meters to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision instrument protective housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision instrument protective housing includes a housing, a bottom cover rotatably mounted on the front side of the housing via a hinge, two telescopic rods fixedly inserted into the rear surface of the bottom cover, the other ends of the two telescopic rods being connected to a first compression plate, two first springs connecting the first compression plate and the bottom cover, the first springs being sleeved on the outside of the corresponding telescopic rods, an inner plate located near the top wall of the housing, the inner plate dividing the internal space of the housing in two, the lower space of the inner plate being used for storing instruments, the upper space of the inner plate being a shock-absorbing buffer zone containing multiple buffer springs, a threaded sleeve inserted at the middle of the top of the housing, the other end of the threaded sleeve penetrating the inner plate, a matching stud inserted into the threaded sleeve, a handle connected to the top of the stud and a second compression plate rotatably connected to the bottom end, a snap-fit ​​assembly located on the side of the bottom cover away from the hinge, and an auxiliary fixing mechanism located on the outer surface of the housing.

[0007] As a preferred embodiment of this utility model: the auxiliary fixing mechanism includes two boxes, which are symmetrically arranged in a figure-eight shape on the outer surfaces of the left and right sides of the shell. The internal space of the boxes is connected to the internal space of the shell. The cross-section of the internal space of the boxes is rectangular. A threaded rod is rotatably provided on the bottom wall of the inner wall of the boxes. One end of the threaded rod is connected to a rotating shaft, and the other end of the rotating shaft is connected to a knob. The knob is rotatably connected to the outer surface of the boxes. A threaded sleeve is threadedly fitted on the other end of the threaded rod. A rubber protrusion is provided on the other end of the threaded sleeve, and the threaded sleeve cooperates with the internal space of the boxes.

[0008] As a further preferred embodiment of this utility model: the snap-fit ​​assembly includes a second spring, a push button, a snap block, a snap groove, and a connecting rod. A groove is formed on the surface of the bottom cover away from the hinge. A snap block adapted to the groove is slidably disposed in the groove. One end of the second spring is connected to the bottom wall of the groove and the other end is connected to the snap block. A snap groove is formed on the inner side wall of the housing for the snap block to slide into. A sliding groove communicating with the groove is formed on the front surface of the bottom cover. A connecting rod adapted to the groove is slidably disposed in the sliding groove. One end of the connecting rod is connected to the snap block and the other end is connected to a push button. The push button is slidably disposed on the front surface of the bottom cover.

[0009] As a further preferred embodiment of this utility model: several limiting blocks are symmetrically provided on the outer walls of the left and right sides of the second extrusion plate, and a limiting groove is provided on the inner wall of the shell for the limiting blocks to slide into.

[0010] As a further preferred embodiment of this utility model: the top edge of the first extrusion plate is rounded, and the top of the first extrusion plate is provided with a first sponge layer.

[0011] As a further preferred embodiment of this utility model: a second sponge layer is provided at the bottom of the second extrusion plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this device, for rectangular instruments, after closing the bottom cover, the first pressing plate on the rear side of the bottom cover will abut against the bottom of the instrument, the telescopic rod will retract, and the first spring will be compressed to generate elastic force, initially pressing and fixing the instrument. Then, rotating the handle will drive the second pressing plate downward through the stud until the second sponge layer abuts against the top surface of the instrument, thus pressing and fixing the instrument again, fully ensuring the instrument's position is fixed. For round instruments, an auxiliary fixing mechanism is required. The operator only needs to rotate the knob, which drives the threaded rod to rotate, and the threaded sleeve rod is subjected to the action of the threaded connection and... The rectangular space inside the housing acts as a limiting element, allowing the threaded sleeve to move along its length. The sleeve extends into the housing, causing two rubber protrusions to abut against the curved outer surface of the circular instrument from different directions, thus fixing and limiting the instrument's position and ensuring effective protection. Simultaneously, the inner plate enhances the strength of the protective shell, while the anti-collision buffer zone and its multiple buffer springs significantly reduce the impact force, further improving the device's protective effect. It is highly practical, simple, and convenient to operate. This device is suitable for instruments of various shapes, making it widely applicable and worthy of promotion. Attached Figure Description

[0020] Please see Figure 1-5 In this embodiment of the utility model, a high-precision instrument protective housing includes a housing 1. A bottom cover 8 is rotatably provided on the front side of the housing 1 via a hinge. Two telescopic rods 18 are fixedly inserted into the rear surface of the bottom cover 8. The other ends of the two telescopic rods 18 are connected to a first compression plate 16. Two first springs 17 are connected between the first compression plate 16 and the bottom cover 8. The first springs 17 are sleeved on the outside of the corresponding telescopic rods 18. An inner plate 24 is provided near the top wall inside the housing 1. The inner plate 24 divides the internal space of the housing 1 into two parts. The space below the inner plate 24 is used to store instruments. The space above the inner plate 24 is a collision buffer zone. Multiple buffer springs 25 are provided in the collision buffer zone. A threaded sleeve 9 is inserted at the middle of the top of the housing 1. The other end of the threaded sleeve 9 passes through the inner plate 24. A stud 3 that cooperates with it is inserted into the threaded sleeve 9. The top end of the stud 3 is connected to a handle 2, and the bottom end is rotatably connected to a second compression plate 26. A snap-fit ​​assembly is provided on the side of the bottom cover 8 away from the hinge. An auxiliary fixing mechanism is provided on the outer surface of the housing 1.

[0021] The auxiliary fixing mechanism includes two boxes 4, which are symmetrically arranged in a figure-eight shape on the outer surfaces of the left and right sides of the shell 1. The internal space of the box 4 is connected to the internal space of the shell 1. The cross-section of the internal space of the box 4 is rectangular. A threaded rod 13 is rotatably provided on the bottom wall of the inner side of the box 4. One end of the threaded rod 13 is connected to a rotating shaft 14, and the other end of the rotating shaft 14 is connected to a knob 5. The knob 5 is rotatably connected to the outer surface of the box 4. A threaded sleeve 12 is threadedly fitted on the other end of the threaded rod 13. A rubber protrusion 11 is provided on the other end of the threaded sleeve 12. The threaded sleeve 12 cooperates with the internal space of the box 4.

[0022] The snap-fit ​​assembly includes a second spring 23, a push button 6, a snap block 21, a snap groove 22, and a connecting rod 20. A groove 19 is provided on the side of the bottom cover 8 away from the hinge. A snap block 21 is slidably disposed in the groove 19. One end of the second spring 23 is connected to the bottom wall of the groove 19 and the other end is connected to the snap block 21. A snap groove 22 is provided on the inner side wall of the housing 1 for the snap block 21 to slide into. A sliding groove 7 communicating with the groove 19 is provided on the front side surface of the bottom cover 8. A connecting rod 20 is slidably disposed in the sliding groove 7. One end of the connecting rod 20 is connected to the snap block 21 and the other end is connected to the push button 6. The push button 6 is slidably disposed on the front side surface of the bottom cover 8.

[0023] The second extrusion plate 26 has several limiting blocks 27 symmetrically arranged on the outer walls of its left and right sides. The inner wall of the housing 1 has a limiting groove for the limiting blocks 27 to slide into. The limiting blocks 27 and the limiting groove are connected to guide and stabilize the movement of the second extrusion plate 26, thereby improving the extrusion and fixing effect.

[0024] The bottom of the second extrusion plate 26 is provided with a second sponge layer 28, which can provide good protection for the surface of the instrument, especially the display screen.

[0025] The top edge of the first extrusion plate 16 is rounded, and the top of the first extrusion plate 16 is provided with a first sponge layer 15. Since the first extrusion plate 16 will rotate with the bottom cover 8, when it rotates to the bottom of the instrument and is extruded, the setting of the first sponge layer 15 and the rounded corner design improve the feasibility and convenience of the device's function.

[0026] Specifically, in use, for rectangular instruments, such as Figure 5 As shown, after the bottom cover 8 is closed, the first compression plate 16 on the rear side of the bottom cover 8 will abut against the bottom of the instrument, the telescopic rod 18 will retract, and the first spring 17 will be compressed to generate elastic force, initially compressing and fixing the instrument. Then, the handle 2 will be rotated, and the second compression plate 26 will move downward through the stud 3 until the second sponge layer 28 abuts against the top surface of the instrument, that is, the instrument will be compressed and fixed again, fully ensuring that the instrument position is fixed; for round instruments, such as Figure 2As shown, an auxiliary fixing mechanism is required. The operator only needs to turn the knob 5. The knob 5 drives the threaded rod 13 to rotate. The threaded sleeve 12 is subject to the action of the threaded connection and the limiting effect of the rectangular space inside the housing 4. Therefore, the threaded sleeve 12 can move along the length of the threaded rod 13, that is, the threaded sleeve 12 extends into the housing 1, so that the two rubber protrusions 11 abut against the arc-shaped outer surface of the circular instrument from different directions for fixing and limiting, which fully ensures the fixed position of the instrument and ensures the protective effect of the instrument. At the same time, the inner plate 24 enhances the strength of the protective shell, while the anti-collision buffer and the multiple buffer springs 25 inside the anti-collision buffer can greatly reduce the impact force generated by the collision, further improving the protective effect of this device. It is highly practical and easy to operate. This device is suitable for instruments of different shapes, has higher applicability, and is worth promoting.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
