Description

Technical Field

[0001] This utility model relates to the field of analytical chemistry instrument technology, and in particular to a handheld portable standard gas dilution device. Background Technology

[0002] A gas dilution device is a precision instrument used to mix high-concentration gas samples with a diluent gas (such as clean air, nitrogen, or zero gas) in a precise ratio to obtain a desired low-concentration standard gas. It is widely used in environmental monitoring, industrial safety, medical equipment calibration, laboratory analysis, and gas sensor testing, and is a key tool for achieving accurate gas concentration control and calibration.

[0003] The existing patent, CN214844374U, discloses a portable standard gas dilution device, including a housing. The housing comprises an upper shell, a lower shell, a front panel, and a rear panel. The upper shell has a flip cover. The upper and lower shells are interlocked to form a ring structure. The front and rear panels are respectively positioned at notches on both sides of the ring structure. A support plate is located inside the housing. A gas mixing container is mounted on the support plate. A standard gas storage container and a zero gas storage container are connected to both sides of the gas mixing container. An analytical instrument for analyzing the mixed gas in the gas mixing container is located on the inner side of the front panel. A buffer device is symmetrically positioned between the support plate and the housing. This device ensures dilution under stable gas flow conditions, increasing the accuracy of configuring the diluted gas concentration under dynamic conditions. The flip cover and buffer device make the device easy to assemble and disassemble, simple to use, more portable, and lower in cost, making it applicable to various laboratories.

[0004] While the above scheme can ensure dilution under stable gas flow conditions and increase the accuracy of setting the dilution gas concentration under dynamic conditions, the device installs the buffer device at the bottom of the dilution device and does not directly connect it to the dilution device. This design may cause the buffer device to collide during the transportation of the device, thereby affecting the stability of the standard gas dilution device.

[0005] Therefore, how to provide a portable standard gas dilution device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a handheld, portable standard gas dilution device to solve the problems mentioned in the background art.

[0007] A portable standard gas dilution device according to an embodiment of the present invention includes a gas storage tank and a transport box. A gas mixing tank is disposed inside the transport box. Two fixing blocks are fixedly connected to one side of the gas mixing tank. A triangular support is fixedly connected to the opposite side of the two fixing blocks. A linkage bar is fixedly connected to one side of the triangular support. A first trapezoidal block is fixedly connected to the other side of the linkage bar. A partition is fixedly installed inside the transport box. Dampers are fixedly connected to the inner walls of both sides of the transport box. A second trapezoidal block is fixedly connected to the other side of each of the two dampers. A first spring is fixedly connected to one side of each of the two second trapezoidal blocks. The two first springs are fixedly connected to the inner wall of the opposite side of the transport box. The two second trapezoidal blocks slide on the outer surface of one side of the partition.

[0008] As a further preferred embodiment of this utility model: a fixed rod is fixedly connected to one side of the inner wall of both sides of the transport box, and a movable disc is movably sleeved on the outer surface of each of the two fixed rods. A second spring is fixedly connected to the opposite side of each of the two movable discs. The two second springs are fixedly connected to the inner wall of the opposite side of the transport box. An inclined brace is fixedly connected to the outer surface of each of the two movable discs near the top. The two inclined braces are hinged to the outer surfaces of both sides of the linkage bar.

[0009] As a further preferred embodiment of this utility model: a limiting ring is fixedly installed inside the transport box, a telescopic rod is fixedly connected to one side of the limiting ring, the telescopic rod is fixedly connected to the inner wall of one side of the transport box, a third spring is fixedly connected to one side of the telescopic rod, a threaded rod is movably connected inside the limiting ring, and a pad is fixedly connected to one side of the threaded rod.

[0010] As a further preferred embodiment of this utility model: the gas storage tank is disposed inside the limiting ring, the output end of the top of the limiting ring is fixedly connected to a first gas pipe, a buffer device is fixedly installed on the top of the gas storage tank, the output end of the buffer device is fixedly connected to a second gas pipe, the buffer device is fixedly connected inside the first gas pipe, the first gas pipe is fixedly connected to the input end of the gas mixing tank, and a wooden board is fixedly connected to one side of the gas mixing tank.

[0011] As a further preferred embodiment of this utility model: a third gas pipe is fixedly connected to the output end of the gas mixing tank, and an analyzer is fixedly connected to the other side of the third gas pipe.

[0012] As a further preferred embodiment of this utility model: the top of the transport box is fixedly connected to a handle, the side of the transport box is movably connected to a door, and a wooden board is provided on one side of the transport box.

[0013] The beneficial effects of this utility model are as follows: When in use, the user holds the handle and carries the transport box out of the laboratory. During the movement, the shaking force is applied to the gas storage tank and the gas mixing tank. The gas mixing tank shakes and moves to both sides. One side is directly buffered by the damping device, while the pressure on the other side is transmitted to one side through the fixed block and the triangular support. The linkage bar is squeezed by the force, which causes it to push the second trapezoidal blocks on both sides, thereby dispersing the pressure of the gas mixing tank to one side to three directions for buffering. The pressure buffered to the other two sides can be maximized with the cooperation of the damper and the first spring.

[0014] The beneficial effects of this utility model are as follows: When in use, when the linkage bar moves to one side, the inclined support pushes the movable disc to slide on the outer surface of the fixed rod, thereby compressing and deforming the second spring. When it is buffered in multiple directions, the impact force is very small. When the pressure disappears, the rebound effect of the first and second springs will push the first trapezoidal block to rebound to a distance, so that the position of the transport box will not change and it can meet the next buffering force. The gas storage tank is placed inside the limiting ring. Due to the telescopic effect of the telescopic rod, it can be used to accommodate gas storage tanks of different sizes. With the cooperation of the telescopic rod and the third spring, one side of the gas storage tank is fixedly supported. Then, the threaded rod is rotated to make the pad move. The pad is attached to the outer surface of the other side of the gas storage tank and fixed thereon. At this time, both sides of the gas storage tank are fixed to prevent shaking during the movement. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figures 1 to 4 As shown, the system includes a gas storage tank 1 and a transport box 101. A gas mixing tank 102 is installed inside the transport box 101. Two fixing blocks 103 are fixedly connected to one side of the gas mixing tank 102. A triangular support 104 is fixedly connected to the opposite side of the two fixing blocks 103. A linkage bar 105 is fixedly connected to one side of the triangular support 104. A first trapezoidal block 106 is fixedly connected to the other side of the linkage bar 105. A partition 107 is fixedly installed inside the transport box 101. Dampers 108 are fixedly connected to the inner walls of both sides of the transport box 101. Second trapezoidal blocks 110 are fixedly connected to the other side of each of the two dampers 108. Each side of block 110 is fixedly connected to a first spring 109. Both first springs 109 are fixedly connected to the inner wall of the opposite side of the transport box 101. The two second trapezoidal blocks 110 slide on the outer surface of one side of the partition 107. The pressure on one side of the gas mixing tank 102 is transmitted to one side through the fixed block 103 and the triangular support 104. The linkage bar 105 is squeezed and pushes the second trapezoidal blocks 110 on both sides, thereby dispersing the pressure of the gas mixing tank 102 to one side to three directions for buffering. The pressure buffered to the other two sides can be buffered to the maximum extent with the cooperation of the damper 108 and the first spring 109.

[0023] refer to Figures 1 to 4As shown, fixed rods 111 are fixedly connected to opposite sides of the inner walls of the transport box 101. Movable discs 113 are movably fitted onto the outer surfaces of the two fixed rods 111. Second springs 112 are fixedly connected to opposite sides of the two movable discs 113. The two second springs 112 are fixedly connected to the inner walls of opposite sides of the transport box 101. Diagonal braces 114 are fixedly connected to the outer surfaces of the two movable discs 113 near the top. The two diagonal braces 114 are hinged to the outer surfaces of the two sides of the linkage bar 105. When the linkage bar 105 moves to one side, the diagonal braces 114 push the movable discs 113 to slide on the outer surfaces of the fixed rods 111, thereby compressing and deforming the second springs 112. When buffered in multiple directions, the impact force is very small. When the pressure disappears, the rebound effect of the first spring 109 and the second spring 112 will push the first trapezoidal block 106 to rebound to a distance, so that the position of the transport box 101 will not change and can be ready to receive the next buffering force.

[0024] refer to Figures 1 to 4 As shown, a limiting ring 115 is fixedly installed inside the transport box 101. A telescopic rod 116 is fixedly connected to one side of the limiting ring 115. The telescopic rod 116 is fixedly connected to the inner wall of one side of the transport box 101. A third spring 117 is fixedly connected to one side of the telescopic rod 116. A threaded rod 118 is movably connected inside the limiting ring 115. A pad 119 is fixedly connected to one side of the threaded rod 118. The gas storage tank 1 is placed inside the limiting ring 115. Due to the telescopic effect of the telescopic rod 116, it can be used to accommodate gas storage tanks 1 of different sizes. With the cooperation of the telescopic rod 116 and the third spring 117, one side of the gas storage tank 1 is fixedly supported. Then, the threaded rod 118 is rotated to move the pad 119. The pad 119 is attached to the outer surface of the other side of the gas storage tank 1 to fix it. At this time, both sides of the gas storage tank 1 are fixed to prevent shaking during the journey.

[0025] refer to Figures 1 to 4 As shown, the gas storage tank 1 is located inside the limiting ring 115. The output end of the top of the limiting ring 115 is fixedly connected to the first gas pipe 120. A buffer device 121 is fixedly installed on the top of the gas storage tank 1. The output end of the buffer device 121 is fixedly connected to the second gas pipe 122. The buffer device 121 is fixedly connected inside the first gas pipe 120. The first gas pipe 120 is fixedly connected to the input end of the gas mixing tank 102. A wooden board 126 is fixedly connected to one side of the gas mixing tank 102. Gas enters the interior of the first gas pipe 120 from the second gas pipe 122 through the action of the buffer device 121. The first gas pipe 120 transmits the gas into the interior of the gas mixing tank 102. The gas mixing tank 102 then discharges the gas.

[0026] refer to Figures 1 to 4As shown, a third gas pipe 123 is fixedly connected to the output end of the gas mixing tank 102, and an analyzer 124 is fixedly connected to the other side of the third gas pipe 123. The gas mixing tank 102 then dilutes the gas and enters the analyzer 124 through the third gas pipe 123 for analysis.

[0027] refer to Figures 1 to 4 As shown, a handle 125 is fixedly connected to the top of the transport box 101, a door 127 is movably connected to one side of the transport box 101, a wooden board 126 is provided on one side of the transport box 101, the handle 125 makes it easy for the user to move the equipment to any location, the wooden board 126 strengthens the sturdiness of one side to prevent the damper 108 from damaging it, and the door 127 makes it easy for the user to open.

[0028] Working principle: During use, the user holds handle 125 to carry the transport box 101 out of the laboratory. During the movement, the swaying force is applied to the gas storage tank 1 and the gas mixing tank 102. The gas mixing tank 102 sways and moves to both sides. One side is directly buffered by the damping device, while the pressure on the other side is transmitted to one side through the fixed block 103 and the triangular support 104. The linkage bar 105 is compressed by the force, which causes it to push the second trapezoidal blocks 110 on both sides, thereby dispersing the pressure of the gas mixing tank 102 to one side into three directions for buffering. The pressure buffered to the other two sides is maximized by the cooperation of the damper 108 and the first spring 109. When the linkage bar 105 moves to one side, the diagonal support 114 pushes the movable plate 113 to slide on the outer surface of the fixed rod 111, thereby compressing and deforming the second spring 112. When buffered in multiple directions, the impact is minimized. The force is already very small. When the pressure disappears, the rebound effect of the first spring 109 and the second spring 112 will push the first trapezoidal block 106 back to a distance, so that the position of the transport box 101 will not change and can be ready to receive the next buffering force. The gas storage tank 1 is placed inside the limiting ring 115. Due to the telescopic effect of the telescopic rod 116, it can be used for gas storage tanks 1 of different sizes. With the cooperation of the telescopic rod 116 and the third spring 117, one side of the gas storage tank 1 is fixedly supported. Then, the threaded rod 118 is rotated to cause the pad 119 to move. The pad 119 is attached to the outer surface of the other side of the gas storage tank 1 to fix it. At this time, both sides of the gas storage tank 1 are fixed to prevent shaking during the journey. This solves the problem that the buffer device will collide during the transportation of the device carried by the carrier, which will affect the stability of the standard gas dilution device.
