Description

Technical Field

[0001] The utility model belongs to the technical field of radio frequency test shielding boxes, and particularly relates to a new type of high-performance audio and radio frequency integrated shielding box. Background Technique

[0002] A radio frequency shielding box, also known as a shielding box or isolation box, is a shielding body of various shapes made of conductive or magnetic materials that confines electromagnetic energy within a certain space range and is a metal body used to suppress radiation interference. It also processes conduction and radiation to provide a test environment without interference for the wireless communication device under test.

[0003] The utility model with the publication number CN218331698U discloses a radio frequency test shielding box, including a base. A shielding box body is fixedly installed at the top of the base. A moisture-proof mechanism is arranged at the bottom of the shielding box body. The moisture-proof mechanism includes a receiving bin, a heating rod group, an isolation mesh plate, and desiccant particles. A receiving bin is fixedly installed at the bottom of the shielding box body and inside the base. In the above application document, the air in the shielding box body is extracted through an extraction pipe by an exhaust fan and enters the receiving bin, where it is heated by the heating rod group. Then, the heated humid air enters the desiccant particles through the isolation mesh plate, and the water vapor is adsorbed as effectively as possible. Finally, the dry hot air returns to the shielding box body through the exhaust pipe again, ensuring that the shielding box body can be placed dry after the detection. However, the isolation mesh plate and the desiccant particles may become blocked or ineffective after long-term use, and it will be rather troublesome to replace them at this time. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of high-performance audio and radio frequency integrated shielding box to solve the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model relates to a novel high-performance integrated audio and radio frequency shielding box, which comprises a shielding box. A bottom box is fixedly connected to the bottom of the shielding box. A circulating pump is fixedly installed at the bottom inside the bottom box. An air inlet pipe and an air outlet pipe are respectively arranged on both sides of the circulating pump. One end of the air inlet pipe far away from the circulating pump penetrates and is fixedly connected to the bottom of the shielding box. A heater is arranged in the middle of the air outlet pipe. A return pipe penetrates and is fixedly connected to the bottom of the shielding box. A dehumidification mechanism convenient for replacement is arranged at the bottom inside the bottom box. The dehumidification mechanism convenient for replacement comprises a dehumidification box. The dehumidification box is fixedly connected to the bottom inside the bottom box. An installation box is inserted into the dehumidification box. A dust removal plate and a dehumidification plate are arranged inside the installation box. A plug block is fixedly connected to the side of the installation box. A groove is formed on one side of the plug block far away from the dehumidification plate. A telescopic spring is arranged inside the groove. An arc-shaped block is slidably connected inside the groove through the telescopic spring. A plug cylinder is fixedly connected to the side of the dehumidification box. A compression spring is arranged at the rear end inside the plug cylinder. A clamping groove is formed on the inner wall of the plug cylinder. A pressing rod penetrates and is slidably connected to the side of the clamping groove. Speed control mechanisms are arranged at the top and bottom of the plug block.

[0007] Further, one end of the air outlet pipe far away from the circulating pump and one end of the return pipe far away from the bottom of the shielding box respectively penetrate and are fixedly connected to both sides of the dehumidification box. The air discharged from the air outlet pipe will enter the dehumidification box and finally be discharged back into the shielding box through the return pipe.

[0008] Further, the arc-shaped block is made of stainless steel material. The opening size of the groove is the same as that of the clamping groove. The arc-shaped block made of stainless steel material has high strength and is not easy to rust and damage. When the arc-shaped block is clamped into the clamping groove, the installation box cannot leave the inside of the dehumidification box.

[0009] Further, the depth of the groove is greater than the length of the arc-shaped block. The arc surface of the arc-shaped block faces the rear end. When the arc surface of the arc-shaped block is squeezed, it will move into the groove, and the arc-shaped block can be completely retracted into the groove.

[0010] Further, the speed control mechanism comprises a bracket. The bracket is fixedly connected to the plug block. A runner is rotatably connected to the inner side of the bracket. A groove body is formed on the surface of the runner. An elastic pull rope is arranged inside the groove body. A resistance block is slidably connected inside the groove body through the elastic pull rope.

[0011] Further, the surface of the runner is in close contact with the inner wall of the plug cylinder in the initial state. When the plug block moves in the plug cylinder, it will drive the runner to rotate due to the friction with the inner wall of the plug cylinder.

[0012] Further, the resistance block is made of rubber material, and the resistance block is completely inside the groove body in the initial state. When the resistance block made of rubber material contacts the inner wall of the plug cylinder, resistance will be generated.

[0013] The utility model has the following beneficial effects:

[0014] 1. By providing a convenient dehumidification mechanism, the utility model can dust and dehumidify the air entering the dehumidification box through the cooperation of a dust removal plate and a dehumidification plate. When the dust removal plate and the dehumidification plate need to be replaced, pressing the pressure rods on the sides of the insertion cylinders on both sides of the dehumidification box can make the installation box pop out, facilitating the replacement of the dust removal plate and the dehumidification plate.

[0015] 2. By providing a speed control mechanism, the utility model can slow down the speed of the installation box when it pops out through the cooperation of components such as a bracket, a runner, and an elastic pull rope, and it will not be affected when reinstalling the installation box, preventing damage to the installation box caused by too fast a pop-out speed and resulting in impact.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-6 , the present invention is a new type of high-performance audio and radio frequency integrated shield box, including a shield box 1. The bottom of the shield box 1 is fixedly connected with a bottom box 2. The bottom of the inner part of the bottom box 2 is fixedly installed with a circulation pump 3. An air inlet pipe 4 and an air outlet pipe 5 are respectively arranged on both sides of the circulation pump 3. One end of the air inlet pipe 4 far away from the circulation pump 3 penetrates and is fixedly connected with the bottom of the shield box 1. A heater 6 is arranged in the middle of the air outlet pipe 5. The bottom of the shield box 1 penetrates and is fixedly connected with a return pipe 7. A convenient replacement dehumidification mechanism 8 is arranged at the bottom of the inner part of the bottom box 2. The convenient replacement dehumidification mechanism 8 includes a dehumidification box 81. The dehumidification box 81 is fixedly connected to the bottom of the inner part of the bottom box 2. An installation box 82 is inserted into the inner part of the dehumidification box 81. A dust removal plate 83 and a dehumidification plate 84 are arranged in the inner part of the installation box 82. An insert block 85 is fixedly connected to the side of the installation box 82. A groove 86 is opened on one side of the insert block 85 far away from the dehumidification plate 84. A telescopic spring 87 is arranged in the groove 86. An arc-shaped block 88 is slidably connected in the groove 86 through the telescopic spring 87. An insert cylinder 89 is fixedly connected to the side of the dehumidification box 81. A compression spring 810 is arranged at the rear end of the inner part of the insert cylinder 89. A card slot 811 is opened on the inner wall of the insert cylinder 89. A pressure rod 812 penetrates and is slidably connected to the side of the card slot 811. Speed control mechanisms 9 are arranged at both the top and the bottom of the insert block 85.

[0028] One end of the air outlet pipe 5 far away from the circulation pump 3 and one end of the return pipe 7 far away from the bottom of the shield box 1 respectively penetrate and are fixedly connected to both sides of the dehumidification box 81. The air discharged from the air outlet pipe 5 will enter the dehumidification box 81 and finally be discharged back into the shield box 1 through the return pipe 7.

[0029] The material of the arc-shaped block 88 is stainless steel. The opening size of the groove 86 is the same as that of the clamping groove 811. The arc-shaped block 88 made of stainless steel has high strength and is not easy to rust and damage. When the arc-shaped block 88 is clamped into the clamping groove 811, the installation box 82 cannot leave the inside of the dehumidification box 81.

[0030] The depth of the groove 86 is greater than the length of the arc-shaped block 88. The arc surface of the arc-shaped block 88 faces the rear end. When the arc surface of the arc-shaped block 88 is squeezed, it will move into the groove 86, and the arc-shaped block 88 can be completely retracted into the groove 86.

[0031] The speed control mechanism 9 includes a bracket 91. The bracket 91 is fixedly connected to the plug 85. A runner 92 is rotatably connected to the inner side of the bracket 91. A groove 93 is formed on the surface of the runner 92. An elastic pull rope 94 is arranged inside the groove 93. A resistance block 95 is slidably connected to the inside of the groove 93 through the elastic pull rope 94.

[0032] The surface of the runner 92 is initially in close contact with the inner wall of the socket 89. When the plug 85 moves in the socket 89, it will drive the runner 92 to rotate due to the friction with the inner wall of the socket 89.

[0033] The resistance block 95 is made of rubber, and the resistance block 95 is completely inside the groove 93 in the initial state. When the rubber resistance block 95 contacts the inner wall of the socket 89, it will generate resistance.

[0034] A specific application of this embodiment is as follows: When it is necessary to dry and remove dust from the air inside the shielding box 1, the circulation pump 3 is turned on to extract the air inside the shielding box 1 through the air inlet pipe 4 and discharge it into the dehumidification box 81 through the air outlet pipe 5. The heater 6 can be turned on to heat the air inside the air outlet pipe 5. The air entering the dehumidification box 81 will pass through the inside of the installation box 82, and the dust removal plate 83 and the dehumidification plate 84 inside the installation box 82 will remove dust and moisture from the air. Finally, the air after dust removal and dehumidification is discharged back into the shielding box 1 through the return pipe 7. When the dust removal plate 83 and the dehumidification plate 84 inside the installation box 82 need to be replaced after long-term use, the pressure rods 812 on the sides of the two insertion cylinders 89 are pressed so that the corresponding arc-shaped blocks 88 leave the card slots 811 and retract into the grooves 86. At this time, the compression spring 810 will rebound to drive the insertion block 85 to leave the insertion cylinder 89, so that the entire installation box 82 pops out, facilitating the replacement of the dust removal plate 83 and the dehumidification plate 84. Subsequently, the telescopic spring 87 rebounds to drive the arc-shaped block 88 to return to its original position. When reinstalling the installation box 82, the installation box 82 is inserted into the dehumidification box 81, and the insertion block 85 is aligned with the insertion cylinder 89 and inserted. The compression spring 810 is gradually squeezed and tightened. At first, the arc surface of the arc-shaped block 88 is squeezed and compressed into the groove 86, and the telescopic spring 87 is tightened. When the groove 86 coincides with the card slot 811, the telescopic spring 87 rebounds to drive the arc-shaped block 88 to snap into the card slot 811, making the insertion block 85 unable to leave the card slot 811, so that the installation box 82 cannot leave the inside of the dehumidification box 81 to complete the installation of the installation box 82. Moreover, during the process of the compression spring 810 rebounding to drive the insertion block 85 to leave the insertion cylinder 89, the moving speed of the insertion block 85 is relatively fast, which will cause the runner 92 to rotate rapidly due to friction with the inner wall of the insertion cylinder 89. The centrifugal force generated by the rapid rotation of the runner 92 will throw the resistance block 95 out of the groove body 93 to contact the inner wall of the insertion cylinder 89. When the rubber resistance block 95 contacts the inner wall of the insertion cylinder 89, it will generate resistance to slow down the ejection speed of the insertion block 85, thereby slowing down the ejection speed of the installation box 82 to prevent impact damage to the installation box 82.
