The linear guide rail is fixedly connected to the housing and is located on the side of the housing. The moving frame is slidably connected to the linear guide rail and is located on the side of the linear guide rail.

[0008] Wherein, the first reset mechanism includes a push rod and a spring. The push rod is slidably arranged on the fixed frame of the lever. The spring is fixedly connected to the push rod and is fixedly connected to the fixed frame of the lever, and is located between the push rod and the fixed frame of the lever.

[0009] Wherein, the moving frame includes a slider and a moving frame body. The slider is slidably connected to the linear guide rail and is located on the side of the linear guide rail.

[0011] A test tube rack transmission device for extending the pushing distance without power. The test tube rack can be pushed to slide over the fixed plate and slide from the first device to the second device. The fixed plate also supports the casing. The lever fixing bracket is arranged inside the sliding box and is used for rotatably installing the on-line bridge lever. A first reset mechanism is installed between the on-line bridge lever and the lever fixing bracket.

The mounting bracket, the stud and the nut cooperate to rotatably install the secondary pushing rod inside the moving frame. When an external force acts on the secondary pushing rod, the secondary pushing rod can be pushed back into the moving frame. When the external force disappears, the torsion spring will pull the cylinder and drive the secondary pushing rod to reset and stand up. The second reset mechanism is used for the reset of the moving frame. During use, the sampling lever is pushed for the first time to drive the test tube rack to slide along the fixed plate. The test tube rack first presses down the secondary pushing rod. The sampling lever continuously presses the secondary pushing rod and then pushes the test tube rack to continue sliding, pressing down the on-line bridge lever. After moving to the limit position, the first reset mechanism drives the on-line bridge lever to reset and abut against the back of the test tube rack. The sampling lever retracts. The torsion spring drives the secondary pushing rod to reset. The sampling lever is pushed for the second time. At this time, since there is no test tube rack pressing down the secondary pushing rod, the secondary pushing rod will not rotate and retract into the moving frame. The sampling lever will directly abut against the cylinder and directly push the secondary pushing rod, driving the moving frame and thus driving the sliding box to slide to the left. The on-line bridge lever pushes the test tube rack to continue sliding to the left for a certain distance. After feeding, the sampling lever resets. The second reset mechanism drives the moving frame to reset, thus driving the sliding box to reset together. The secondary pushing rod and the on-line bridge lever also reset. Without adding new power additionally, the pushing distance of the test tube rack is extended through two pushes of the sampling lever. Description of the Drawings

The housing 106 includes a shell 119 and a linear guide 120. The first reset mechanism 110 includes a push rod 121 and a spring 122. The moving frame 111 includes a slider 123 and a moving frame body 124. The second reset mechanism 118 includes a mounting plate 125, a constant force clockwork spring 126 and a mounting column 128.

[0025] For this specific embodiment, the first device 101 is provided with a sample introduction lever 104, and the second device 102 is located on the side of the first device 101. The first device 101 is a urine analyzer, and the second device 102 is other instrument that needs to be connected online with the urine analyzer. The second device 102 is connected online with the first device 101 through the online connection component 103 to send the test tube rack 127 in the first device 101 into the second device 102, and the sample introduction lever 104 is used to provide power.

[0026] Among them, the fixed plate 105 is arranged between the first device 101 and the second device 102. The casing 106 is fixedly connected to the fixed plate 105 and is located on the side of the fixed plate 105. The sliding box 107 is located on the side of the casing 106. The lever fixing frame 108 is arranged inside the sliding box 107. The on-line bridge lever 109 is rotatably arranged on the lever fixing frame 108. The first reset mechanism 110 is arranged on the lever fixing frame 108. The moving frame 111 is slidably connected to the casing 106, fixedly connected to the sliding box 107, and is located on the side of the casing 106. The mounting frame 112 is arranged inside the moving frame 111. The secondary push rod 113 is located inside the moving frame 111. The stud 114 passes through the mounting frame 112, the secondary push rod 113 and the moving frame 111. The nut 115 is threadedly installed on one side of the stud 114. The cylinder 116 is fixedly connected to the secondary push rod 113 and is located on one side of the secondary push rod 113. One end of the torsion spring 117 is fixedly connected to the cylinder 116, the other end is fixedly connected to the mounting frame 112, and is sleeved on the stud 114. The second reset mechanism 118 is arranged on the side of the moving frame 111.The test tube rack 127 can be pushed to slide over the fixed plate 105 and slide from the first device 101 to the second device 102. The fixed plate 105 also supports the housing 106. The lever fixing bracket 108 is arranged inside the sliding box 107 and is used for rotatably mounting the on-line bridge lever 109. A first reset mechanism 110 is installed between the on-line bridge lever 109 and the lever fixing bracket 108. After the on-line bridge lever 109 is pressed down, the second reset mechanism 118 can push the on-line bridge lever 109 to rotate and reset. The moving frame 111 can slide on the housing 106 and can also drive the sliding box 107 to slide when sliding to the left. The sliding box 107 is fixedly installed on one side of the moving frame 111. The mounting bracket 112, the stud 114 and the nut 115 cooperate to rotatably mount the secondary push rod 113 inside the moving frame 111. When an external force acts on the secondary push rod 113, the secondary push rod 113 can be pushed and retracted into the inside of the moving frame 111. When the external force disappears, the torsion spring 117 will pull the cylinder 116 to drive the secondary push rod 113 to reset and stand up. The second reset mechanism 118 is used for the reset of the moving frame 111. During use, the sampling lever 104 is pushed for the first time to drive the test tube rack 127 to slide along the fixed plate 105. The test tube rack 127 first presses down the secondary push rod 113. The sampling lever 104 continuously presses the secondary push rod 113 and then pushes the test tube rack 127 to continue sliding, pressing down the on-line bridge lever 109. After moving to the extreme position, the first reset mechanism 110 drives the on-line bridge lever 109 to reset and abut against the back of the test tube rack 127. The sampling lever 104 retracts. The torsion spring 117 drives the secondary push rod 113 to reset. The sampling lever 104 is pushed for the second time. At this time, since there is no test tube rack 127 pressing down the secondary push rod 113, the secondary push rod 113 will not rotate and retract into the moving frame 111. The sampling lever 104 will directly abut against the cylinder 116 and directly push the secondary push rod 113 to drive the moving frame 111, thereby driving the sliding box 107 to slide to the left. The on-line bridge lever 109 pushes the test tube rack 127 to continue sliding to the left for a certain distance. After feeding, the sampling lever 104 resets. The second reset mechanism 118 drives the moving frame 111 to reset, thereby driving the sliding box 107 to reset together. The secondary push rod 113 and the on-line bridge lever 109 also reset. Without adding new power additionally, by pushing the sampling lever 104 twice, the pushing distance of the test tube rack 127 is extended.

[0027] Secondly, the housing 119 is fixedly connected to the fixing plate 105 and is located on the side of the fixing plate 105. The linear guide rail 120 is fixedly connected to the housing 119 and is located on the side of the housing 119. The moving frame 111 is slidably connected to the linear guide rail 120 and is located on the side of the linear guide rail 120. The housing 119 is disposed on the side of the fixing plate 105, and the linear guide rail 120 is used for slidably mounting the moving frame 111.

[0028] Meanwhile, the ejector rod 121 is slidably disposed on the lever fixing bracket 108. The spring 122 is fixedly connected to the ejector rod 121 and is fixedly connected to the lever fixing bracket 108 and is located between the ejector rod 121 and the lever fixing bracket 108. When the on-line bridge lever 109 is pressed down by the test tube rack 127, it will push the ejector rod 121, and the ejector rod 121 will compress the spring 122. After the test tube rack 127 no longer presses the on-line bridge lever 109, the spring 122 drives the ejector rod 121, and the ejector rod 121 pushes the on-line bridge lever 109 to rotate and reset, so that the on-line bridge lever 109 abuts behind the test tube rack 127.

[0029] In addition, the slider 123 is slidably connected to the linear guide rail 120 and is located on the side of the linear guide rail 120. The moving frame body 124 is fixedly connected to the slider 123 and is fixedly connected to the sliding box 107 and is located on one side of the slider 123. The slider 123 is slidably mounted on the linear guide rail 120 to support the moving frame body 124. The moving frame body 124 can drive the sliding rod box to slide together. Inside the moving frame body 124, a secondary push rod 113 and a mounting bracket 112 are installed. There is a box on the side of the moving frame body 124 that is adapted to the slider 123 and just buckles on the slider 123.

[0030] Finally, the mounting plate 125 is fixedly connected to the moving frame body 124 and is located on one side of the moving frame body 124. The mounting post 128 is fixedly connected to the housing 119 and is located inside the housing 119. One end of the constant force spring 126 is fixedly connected to the mounting plate 125 and is sleeved on the mounting post 128. The constant force spring 126 is installed inside the housing 119 through the mounting post 128. When the slider 123 is pulled leftward by force, it will pull the constant force spring 126. When the slider 123 is no longer under force, the constant force spring 126 drives the slider 123 to reset, driving the moving frame body 124 and the sliding box 107 to reset.

[0031] A test tube rack transmission device for extending the pushing distance without power. When in use, the sampling lever 104 makes the first push, driving the test tube rack 127 to slide along the fixed plate 105. The test tube rack 127 first presses down the secondary push rod 113. The sampling lever 104 continuously presses the secondary push rod 113, and then pushes the test tube rack 127 to continue sliding, pressing down the on-line bridge lever 109. After moving to the extreme position, the spring 122 drives the ejector rod 121, and the ejector rod 121 pushes the on-line bridge lever 109 to rotate and reset, so that the on-line bridge lever 109 abuts behind the test tube rack 127. The sampling lever 104 retracts. The torsion spring 117 drives the secondary push rod 113 to reset. The sampling lever 104 makes the second push. At this time, since there is no test tube rack 127 pressing down the secondary push rod 113, the secondary push rod 113 will not rotate and retract into the moving frame body 124. The sampling lever 104 will directly abut against the cylinder 116 and directly push the secondary push rod 113, driving the moving frame body 124, thereby driving the sliding box 107 to slide leftward. The on-line bridge lever 109 pushes the test tube rack 127 to continue sliding leftward for a certain distance. After feeding, the sampling lever 104 resets. The constant force spring 126 pulls the slider 123, driving the moving frame body 124 to reset, thereby driving the sliding box 107 to reset together. The secondary push rod 113 and the on-line bridge lever 109 also reset. Without adding new power additionally, through two pushes of the sampling lever 104, the pushing distance of the test tube rack 127 is extended.
