Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0029] See also Figure 1-Figure 3 .

[0030] The utility model discloses a syringe tightness detection device, comprising:

[0031] Support platform 1;

[0032] A U-shaped tube 2 is provided on the support platform 1. The side wall of the U-shaped tube 2 is marked with scales. When a flowing medium exists in the U-shaped tube 2, the U-shaped tube 2 is used to detect the tightness of the syringe 8.

[0033] A mounting sleeve 3 is provided on the orifice at one end of the U-shaped tube 2. The mounting sleeve 3 is coaxial with the center of the corresponding orifice of the U-shaped tube 2, and a positioning hole 321 for mounting the syringe 8 is provided at the center of the mounting sleeve 3. The mounting sleeve 3 is used to position the syringe 8 to be tested and to connect the syringe 8 to the U-shaped tube 2.

[0034] A sealing component 4 is provided on the mounting sleeve 3 and is used to fill the gap between the syringe 8 and the mounting sleeve 3;

[0035] The clamping component 5 includes two support rods 51 provided on the mounting sleeve 3. The two support rods 51 are arranged opposite to each other and each support rod 51 is provided with a sliding rod 52 near the center of the mounting sleeve 3. A clamping clamp 53 is slidably provided on each sliding rod 52. The clamping clamp 53 is used to clamp the syringe 8. Each clamping clamp 53 is also provided with a pressure component 54, which is used to apply downward pressure to the syringe barrel of the syringe 8.

[0036] The adjustment component 6 includes a first adjustment component 61 disposed on the mounting sleeve 3, the first adjustment component 61 being used to drive the two support rods 51 to move vertically back and forth, and a second adjustment component 62 disposed above the first adjustment component 61. The second adjustment component 62 is disposed on the mounting sleeve 3, one end of the second adjustment component 62 being connected to the two clamping jaws 53, and the second adjustment component 62 being used to control the two clamping jaws 53 to move closer to or further away from each other;

[0037] The detection component 7 is provided on the support platform 1 and is located on one side of the clamping component 5 . The detection component 7 is used to detect the pressure in the syringe barrel of the syringe 8 .

[0038] In specific implementation, when it is necessary to perform a tightness test on the syringe 8, the pintle of the syringe 8 to be tested is inserted into the positioning hole 321. At this time, the pintle of the syringe 8 and the end of the syringe barrel of the syringe 8 close to the pintle are in contact with the sealing component 4. At this time, the sealing component 4 seals the gap between the syringe 8 and the mounting sleeve 3, and the syringe 8 is connected to the cavity of the U-shaped tube 2. First, the first adjustment component 61 is used to drive each clamping clamp 53 to move to the top of the syringe barrel of the syringe 8, and then the second adjustment component 62 is used to control the two clamping clamps 53 to approach each other until each clamping clamp 53 contacts the outer wall of the syringe barrel of the syringe 8 and applies a clamping force toward the center of the syringe 8. At this time, the pressure component 54 applies downward pressure to the syringe barrel of the syringe 8, thereby increasing the sealing effect of the connection between the syringe 8 and the sealing component 4. The syringe 8 is clamped. Afterwards, fluid medium is added into the U-shaped tube 2 until the fluid medium reaches a predetermined scale point. At this time, in the inner cavity of the U-shaped tube 2, there is a sealed space between the fluid medium and the syringe 8 and the pressure is a constant value. At this time, the push rod of the syringe 8 is pushed downward by the detection component 7, so that the space in the syringe barrel of the syringe 8 is compressed and pressure is applied to the inner cavity of the U-shaped tube 2, so that the fluid medium is pushed. The water column level at one end of the U-shaped tube 2 away from the syringe 8 rises, and the current water column level is recorded. The pressure can be calculated by the height difference of the water column level and the aperture of the U-shaped tube 2, and verified with the pressure detected by the detection component 7. At this time, the syringe 8 is left stationary, and the water column level is observed again after it has been left stationary for a predetermined time. If the water column level does not change, the syringe 8 is qualified for tightness. If the water column level drops, the syringe 8 is unqualified for tightness.

[0039] In the present invention, after the syringe 8 is set on the mounting sleeve 3, the first adjusting component 61 drives each clamping clamp 53 to move to the top of the syringe 8 syringe barrel through the cooperation between the clamping component 5 and the adjusting component 6, so as to adapt to different lengths of the syringe 8 syringe barrel, and then adjusts the relative distance between the two clamping clamps 53 through the second adjusting component 62 until the outer wall of the syringe barrel is clamped, so as to adapt to different diameters of the syringe 8 syringe, thereby improving work efficiency.

[0040] Preferably, the fluid medium can be water, oil, etc.

[0041] It should be noted that when the push rod of the syringe 8 moves downward, sufficient space needs to be reserved in the syringe and the push rod cannot be fully pushed to prevent excessive pressure in the syringe to ensure the effectiveness of the test.

[0042] In one embodiment, the mounting sleeve 3 includes a sleeve 31 disposed on the side wall of the corresponding pipe opening of the U-shaped pipe 2 and a mounting platform 32 disposed on the top of the sleeve 31. The height of the mounting platform 32 is flush with the height of the corresponding pipe opening. The positioning hole 321 is provided at the center of the mounting platform 32. Each support rod 51 is vertically slidably provided on the mounting platform 32. The outer wall of the sleeve 31 is provided with threads.

[0043] The first adjustment component 61 includes a ring 611 arranged below each support rod 51, and the ring 611 is sleeved on the sleeve 31 and screwed with the thread on the sleeve 31. A connecting ring 612 is also rotatably sleeved on the ring 611, and the connecting ring 612 is connected to one end of each support rod 51 passing through the bottom surface of the mounting platform 32. When the ring 611 rotates, the connecting ring 612 drives each support rod 51 to move vertically back and forth together, and because the mounting platform 32 and each support rod 51 are vertically slidably matched, when the ring 611 rotates, each support rod 51 prevents the connecting ring 612 from rotating with the sleeve 31.

[0044] With this design, when it is necessary to adapt the height of the syringe barrel 8, the support rods 51 are driven to move vertically back and forth by rotating the ring 611. When the ring 611 rotates, the support rods 51 prevent the connecting ring 612 from rotating along with the sleeve 31, and each support rod 51 drives the corresponding clamping forceps 53 to move together until each clamping forceps 53 moves to one side of the top of the syringe barrel 8.

[0045] In one embodiment, the second adjustment component 62 includes a first screw rod 621 that is rotatably provided on each clamping clamp 53, and the first screw rod 621 is provided with two threaded sections with opposite rotation directions. Each clamping clamp 53 is screwed on the corresponding threaded section. When the first screw rod 621 rotates, it is used to drive the two clamping clamps 53 to move closer to or away from each other. A telescopic plate 622 is also provided on the mounting platform 32, and the telescopic end of the telescopic plate 622 is rotatably connected to one end of the first screw rod 621. When each clamping clamp 53 moves with the corresponding support rod 51, the telescopic end of the telescopic plate 622 telescopes together with the movement of the first screw rod 621.

[0046] With this design, after each clamping clamp 53 is adjusted to a suitable height, the first screw rod 621 is rotated to make each clamping clamp 53 slide relatively on the corresponding sliding rod 52 until each clamping clamp 53 contacts the side wall of the syringe barrel 8 and applies a thrust toward the center of the syringe 8, thereby completing the clamping of the syringe barrel 8. When the clamping clamp 53 moves vertically, the telescopic plate 622 telescopes and extends along with the movement of each clamping clamp 53, thereby avoiding interference with the first screw rod 621.

[0047] In one embodiment, the sealing component 4 includes a sealing ring 41 arranged on the top surface of the mounting platform 32. When the sealing ring 41 contacts the syringe, the sealing ring 41 is used to fill the gap between the syringe and the sealing ring 41. A sealing sleeve 42 is also provided at the positioning hole 321. The sealing sleeve 42 is connected to the mounting platform 32 and has a through hole at the center for the syringe 8 needle plug to pass through. When the syringe 8 needle plug is inserted in the sealing sleeve 42, the sealing sleeve 42 covers the outer wall of the needle plug.

[0048] With this design, when the syringe 8 needs to be connected to the U-shaped tube 2, the needle plug of the syringe 8 is inserted into the sealing sleeve 42. At this time, the end of the syringe barrel of the syringe 8 close to the needle plug contacts the sealing ring 41. The sealing ring 41 fills the gap between the syringe barrel and the sealing ring 41, and the sealing sleeve 42 covers the outer wall of the needle plug, thereby preventing external air from entering the U-shaped tube 2 from the connection point between the syringe 8 and the U-shaped tube 2.

[0049] Preferably, the sealing sleeve 42 can be made of a highly elastic and durable material such as sponge.

[0050] It should be noted that the through hole diameter of the sealing sleeve 42 corresponds to the minimum hole diameter of the syringe 8 needle plug, thereby ensuring that needle plugs of various hole diameters can be inserted and covered in the through hole of the sealing sleeve 42.

[0051] In one embodiment, the pressure-applying assembly 54 includes two support blocks 541 respectively arranged on each clamping clamp 53, the two support blocks 541 are arc-shaped and correspond to the curvature of the corresponding clamping clamp 53, the two support blocks 541 are arranged relative to each other, and a pad 542 is provided at the top of each support block 541 close to the syringe 8, and each pad 542 is provided with an inclined surface. When each clamping clamp 53 clamps the syringe 8, the inclined surface of each pad 542 contacts the top of the syringe and applies downward pressure to the syringe.

[0052] With this design, when each clamping forceps 53 clamps the syringe 8, each pad 542 clamps the outer wall of the syringe together with the corresponding clamping forceps 53 and applies downward pressure to the syringe, further making the syringe fit with the sealing ring 41, thereby improving the sealing between the syringe and the sealing component 4.

[0053] It should be noted that the pad 542 can be made of a material with good elasticity and toughness, such as rubber or silicone, to prevent the pad 542 from squeezing the syringe 8 and causing damage when clamping the syringe 8.

[0054] In one embodiment, a slide groove 11 is provided on the top surface of the support platform 1 , and the slide groove 11 is provided on one side of the clamping component 5 ;

[0055] The detection component 7 includes a slide 71 slidably arranged in the slide groove 11, and a telescopic rod 72 is vertically provided on the slide 71. A pressure sensor 73 is provided on the top of the telescopic end of the telescopic rod 72. The telescopic rod 72 is used to drive the pressure sensor 73 to move vertically back and forth. The pressure sensor 73 is arranged above the push rod of the syringe 8. The pressure sensor 73 is used to detect the pressure applied to the syringe when the push rod is pressed down. A second screw rod 74 is also rotatably provided in the slide groove 11. The second screw rod 74 is arranged along the length direction of the slide groove 11, and one end of the second screw rod 74 passes through the slide 71 and extends out of the slide groove 11. The second screw rod 74 is used to drive the slide 71 to move back and forth in the slide groove 11.

[0056] With this design, after the syringe 8 is clamped, the second screw 74 is rotated and the pressure sensor 73 is driven to move above the push rod of the syringe 8 through the telescopic rod 72. The telescopic end of the telescopic rod 72 contracts and drives the pressure sensor 73 to descend until the pressure sensor 73 contacts the push rod of the syringe 8. At this time, the pressure sensor 73 detects the pressure in the syringe 8 through the push rod. As the telescopic rod 72 continues to descend, the telescopic rod 72 squeezes the push rod of the syringe 8 downward through the pressure sensor 73. At this time, the pressure sensor 73 continues to detect the pressure in the syringe 8 until the push rod moves to the appropriate position. When the syringe 8 is stationary for a period of time, if the value of the pressure sensor 73 does not change, the tightness of the syringe 8 is qualified. If the value of the pressure sensor 73 changes, the tightness of the syringe 8 is unqualified.

[0057] It should be noted that the value of the pressure sensor 73 corresponds to the height change of the water column liquid level in the U-shaped tube 2. When the value of the pressure sensor 73 deviates from the value calculated by the height difference of the water column liquid level in the U-shaped tube 2, the water column liquid level can be made to reach a predetermined height by increasing or decreasing the fluid medium in the U-shaped tube 2, thereby detecting the accuracy of the sealed space in the U-shaped tube 2.

[0058] It should be noted that a retractable adjustment rod can be provided between the pressure sensor 73 and the telescopic rod 72. One end of the adjustment rod is rotatably set at the top of the telescopic end of the telescopic rod 72, and the other end is connected to the pressure sensor 73, so that the position of the pressure sensor 73 can be further adjusted, so that the pressure sensor 73 can contact the syringe 8 more accurately.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
