Description

Technical Field

[0001] The utility model relates to the technical field of mechanical structures, in particular to a chambering indicator device. Background Art

[0002] First, we need to use the rotary lancet correctly. Hold the lancet in your hand, pinch the sides of the lancet with your thumb and index finger, and point the tip downward. Then, gently turn the knob until you hear a "click" indicating that the refill is in place. Next, we use a disposable lancet to collect blood samples. To ensure safety, wash your hands and fingers before blood collection. Next, insert the disposable lancet into the needle slot of the lancet, being careful not to insert it too deep or too shallow to avoid affecting the accuracy of blood collection. Then, gently press the lancet into the surface of the skin, making sure that the end of the needle is in good contact with the blood vessels under the skin. Finally, push the rounded part of the lancet hard to squeeze out the blood and collect it in a test tube or other container for subsequent processing and analysis.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model discloses a loading indication device, including a mounting box 8 and a T-shaped block 4. The rear end of the mounting box 8 is fixedly installed with a slide bar 6 near the left and right sides. The center of the rear end wall of the mounting box 8 is fixedly installed with a pressure sensor 1. The rear end wall of the mounting box 8 is fixedly installed with a spring 7 near the center. The end of the spring 7 away from the mounting box 8 is fixedly installed with a slide block 3. The left and right sides of the slide block 3 are fixedly installed with movable blocks 5. The front of the mounting box 8 is fixedly installed with moving rods 11 near the four corners. The end of the plurality of moving rods 11 away from the mounting box 8 is fixedly installed with a slide block 3. Limiting blocks 12 are fixedly installed, a control panel 10 is provided at the top of the installation box 8 near the front end, a multi-color indicator light 9 is provided at the top of the installation box 8 near the rear end, connecting blocks 18 are fixedly installed at the center of the inner top wall and the inner bottom wall near the front end, adjacent ends of the two connecting blocks 18 are provided with mounting grooves 17, connecting springs 16 are fixedly installed inside the two mounting grooves 17, and limiting balls 15 are provided at adjacent ends of the two connecting springs 16, and limiting grooves 19 are evenly provided at the top and bottom of the T-shaped block 4 near the rear end.

[0024] Specifically, one end of the two slide bars 6 away from the installation box 8 passes through the rear ends of the two movable blocks 5 and is fixedly connected to the center of the inner front end wall of the installation box 8 near the left and right sides, and the connection between the slide bar 6 and the movable block 5 is a movable sleeve.

[0025] In this embodiment, the stability of the slide bar 6 is enhanced and the stability of the rear end slide block 3 during sliding is enhanced.

[0026] Specifically, a clamping rod 2 is fixedly mounted on the rear end of the slider 3 , and the outer surfaces of the clamping rod 2 and the pressure sensor 1 are movably sleeved with the two ends of the spring 7 , respectively. The clamping rod 2 and the pressure sensor 1 are symmetrically arranged.

[0027] In this embodiment, the pressing rod 2 and the pressure sensor 1 are both located inside the spring 7 .

[0028] Specifically, a slide groove 14 is provided on the inner bottom wall of the installation box 8 , the interior of the slide groove 14 is movably connected to the lower surface of the slider 3 near the bottom, and a through groove 13 is provided on the front side of the installation box 8 .

[0029] In this embodiment, the stability of the sliding block 3 when sliding in the sliding groove 14 is enhanced.

[0030] Specifically, the outer surface of the T-shaped block 4 is movably sleeved with the inner part of the through groove 13 near the rear end, and the front sides of the plurality of movable rods 11 respectively penetrate the rear end of the T-shaped block 4 near the four corners and extend out of the front side of the T-shaped block 4. The connection between the movable rod 11 and the T-shaped block 4 is movably sleeved, and the rear end of the T-shaped block 4 is aligned with the slider 3.

[0031] In this embodiment, it is convenient to achieve symmetry during subsequent movement.

[0032] Specifically, the front sides of the plurality of moving rods 11 respectively penetrate the rear end of the T-shaped block 4 near the four corners and are movably sleeved therewith.

[0033] In this embodiment, the stability of the T-block during movement is enhanced.

[0034] Specifically, the surfaces of the two limiting balls 15 are respectively movably connected to the inside of two of the limiting grooves 19 among the plurality of limiting grooves 19 , and the limiting balls 15 are made of metal material.

[0035] In this embodiment, the T-shaped block 4 is limited thereby.

[0036] Specifically, one end of the T-shaped block 4 away from the mounting box 8 is connected to a loading device.

[0037] When in use, the loading device is loaded, so that when the T-shaped block 4 is subjected to external thrust or pressure, the T-shaped block 4 retracts into the installation box 8. When the T-shaped block 4 is retracted into the installation box 8, the limiting ball 15 is retracted into the installation slot 17 by the extrusion force, and the connecting spring 16 is also compressed. When the T-shaped block 4 moves to a certain position and the outlet of the installation slot 17 corresponds to the limiting slot 19, the extrusion force on the limiting ball 15 disappears, and the connecting spring 16 pushes the limiting ball 15 back into the limiting slot 19, thereby limiting the T-shaped block 4 in normal times or in use, making it convenient for the subsequent T-shaped block 4 to connect to the loading structure. When the T-shaped block 4 moves close to the slider 3, the slider 3 is pushed along the slide slot 14 to drive the movable block 5 to move along the slide rod 6 toward the inner rear end wall of the installation slot 17, and the spring 7 is subjected to pressure, so that the rear end of the clamping rod 2 is connected to the inner rear end wall of the installation slot 17. When the front detection end of the pressure sensor 1 is touched, the multi-color indicator light 9 is electrically started when the pressure sensor 1 is under pressure. The greater the pressure on the pressure sensor 1, the more different colors of the multi-color indicator lights 9 will light up, so that the user can directly check whether the gun is loaded from the surface of the installation box 8, and can identify the loading force. After the loading force disappears, when the T-shaped block 4 is no longer subjected to external thrust or pressure, the pressure of the spring 7 also disappears, so that the spring 7 pushes the slider 3 and the clamping rod 2 away from the pressure sensor 1 through pressure, and also pushes the T-shaped block 4 to withdraw from the interior of the installation box 8. The limit column and the connecting spring 16 are affected by the thrust and retract into the installation groove 17, and the T-shaped block 4 returns to its original position. When the thrust of the spring 7 disappears, the limit column and the connecting spring 16 extend out of the installation groove 17 again, which is convenient for next use.

[0038] To sum up, the loading indication device, by setting the pressure sensor 1, the multi-color indicator light 9 and the spring 7, can accurately display the pressure generated when the chamber is loaded when the chamber is under pressure. When used, it is more intuitive and accurate. By setting the slide rod 6 and the slide groove 14, the slider 3 can be limited when sliding, ensuring that the subsequent clamping rod 2 can accurately contact the pressure sensor 1.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
