Technical Field

[0001] The utility model relates to the technical field of instrument protection, in particular to an instrument casing with a dustproof function. Background Art

[0002] Instruments are devices or equipment used to detect, measure, observe and calculate various physical quantities, material components, physical parameters, etc. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments. In the actual use of instruments, they are easily invaded by dust. Too much dust can cause the instrument to malfunction and seriously affect its normal use. Therefore, the instrument needs to be placed in a casing with dustproof function. However, the dust net on the traditional casing is often difficult to remove quickly, resulting in a lot of time spent on cleaning and maintenance. In addition, if the dust net is damaged or needs to be replaced due to excessive dust accumulation, the traditional design may require the replacement of more parts or the entire casing, which increases the cost.

[0023] See also Figure 1-5 As shown, the utility model is an instrument housing with dustproof function, including a housing 1, an opening 2 is opened on the front of the housing 1, a dustproof heat dissipation net 3 is arranged on the inner wall of the opening 2, and a quick disassembly mechanism 4 is arranged between the opening 2 and the dustproof heat dissipation net 3; the quick disassembly mechanism 4 includes a first connecting plate 41 and a second connecting plate 42, the first connecting plate 41 is fixedly connected to the inner wall of the opening 2, the second connecting plate 42 is fixedly connected to the back of the dustproof heat dissipation net 3, the front of the first connecting plate 41 is respectively fixedly connected to two spring bars 43 and two fixing bars 44, and the front faces of the two spring bars 43 are fixedly connected A fastening strip 45 is connected, and a rotating shaft 46 is fixedly connected between the inner walls of the two fastening strips 45. The rotating shaft 46 is rotatably connected between the inner walls of the two fixed strips 44. A clamping strip 47 is fixedly connected to the back of the second connecting plate 42. The two fastening strips 45 are movably connected to the clamping strip 47. By setting a quick disassembly and assembly mechanism 4, the dustproof and heat dissipation net 3 can be quickly disassembled and assembled, so that the dustproof net can be replaced separately, avoiding the high cost of replacing the entire casing or complex components. By replacing the damaged dustproof net in time, dust can be prevented from damaging the internal components of the instrument, thereby extending the service life of the equipment.

[0024] Both sides of the shell 1 are penetrated with movable holes 5, and a clamping and stabilizing mechanism 6 is arranged between the shell 1 and the two movable holes 5. By setting the clamping and stabilizing mechanism 6, the two sides of the instrument can be tightly clamped to ensure its stability and safety in the casing, reduce the risks caused by shaking, collision or damage, and can also adapt to instruments of different sizes and shapes.

[0025] The clamping stabilization mechanism 6 includes a motor 61 and two connecting slide bars 62. The motor 61 is electrically connected to an external power supply and is controlled by an external program. The motor 61 is a stepping motor. By controlling the stepping signal of the motor, the forward and reverse rotation and precise position control of the motor can be realized. When the stepping motor stops working, the position of the output shaft can be kept unchanged and the output shaft can be locked. Through precise drive control, forward and reverse rotation functions and locking the output shaft, the instrument can be accurately clamped and will not be moved by external forces when it is not moving, so that the instrument can be more stable when being clamped. The motor 61 is fixedly connected to the back side of the shell 1 through an L-shaped fixing plate 63. The two connecting slide bars 62 are respectively slidably connected to the inner walls of adjacent movable holes 5. The output end of the motor 61 is fixedly connected to a gear 64. The opposite ends of the two connecting slide bars 62 are fixedly connected to a clamping plate 65. The other ends of the two connecting slide bars 62 are fixedly connected to a rack 66. The height position of the left rack 66 is higher than the height position of the right rack 66. The two racks 66 are meshed with the gear 64.

[0026] A cover plate 7 is slidably connected to the top of the shell 1, a handle 8 is fixedly connected to the top of the cover plate 7, a support leg 9 is fixedly connected to the bottom of the shell 1, and an inlet is opened on the top of the shell 1, and the cover plate 7 is used to cover it to prevent dust.

[0027] Two quick disassembly mechanisms 4 are provided and are symmetrically distributed between the inner wall of the opening 2 and the back of the dustproof and heat dissipation net 3. The design of the two quick disassembly mechanisms 4 makes the disassembly and assembly of the dustproof and heat dissipation net 3 simple and quick.

[0028] Four supporting legs 9 are provided and distributed at the bottom edge of the housing 1 in a rectangular array.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] The working principle of the utility model is as follows: first, hold the dustproof heat dissipation net 3, push the two clips 47 on the back side to insert into the middle position of the two adjacent fastening strips 45, and when the clips 47 are pushed backward, the thrust will cause the two fastening strips 45 to rotate outward in the upper and lower directions respectively through the elastic force of the spring strips 43 pressing toward the back side, and through the rotating shaft 46 in the inner wall of the fixed strip 44; when the clips 47 are fully inserted and pressed against the inner walls of the two fastening strips 45, the two fastening strips 45 are driven to rotate inward in the upper and lower directions relative to each other and return to their original positions by the elastic force of the spring strips 43 pressing forward; at this time, the two fastening strips 45 are completely fitted with the clips 47 and are buckled together to allow quick disassembly and assembly on both sides. The mechanisms 4 all complete the snap connection synchronously, completing the quick installation of the dustproof and heat dissipation net 3 (hold the dustproof and heat dissipation net 3 again, press it and then pull it out to quickly complete the disassembly), then hold the handle 8, pull up the cover 7 through it, slide it out, put the instrument into the shell 1 from above, and then slide the cover 7 into the cover, and finally start the motor 61 to rotate the gear 64 at its output end. When the gear 64 rotates, it drives the two racks 66 meshing with it to move toward the opposite side. When the two racks 66 move, they drive the two connecting slide rods 62 to slide toward the opposite side in the inner walls of the two movable holes 5, so that the two clamping plates 65 clamp and fix the two sides of the instrument.
