Description

Technical Field

[0001] The utility model relates to the technical field of syringe plugging, in particular to a plugging device based on a gel syringe. Background Art

[0002] Gel is a semi-solid substance, usually a mixture of high molecular polymers (such as gelatin, succinate, sodium polyacrylate, etc.) and water or other solvents. Gel has properties similar to those of liquids and solids. It can flow when subjected to force and maintain its shape when not subjected to force. Its special properties make it widely used in biomedicine, biochemistry, pharmaceuticals and other fields.

[0003] In order to facilitate the storage and use of gel, it is necessary to extract and store the gel with the help of a syringe. In order to speed up the production efficiency of the syringe, it is necessary to use a plugging device based on the gel syringe to perform a plugging operation on the injection rod in the syringe. For example, the prior art Chinese Patent Publication No. "CN219730491 U" provides an automatic plugging device for syringes, including a plugging box and a material rack located inside the plugging box. The material rack contains syringes and rubber plugs located on the top of the syringes. A lifting mechanism is provided on the top of the plugging box, and the lifting mechanism presses the rubber plug into the syringe when it descends. By placing the material rack containing the syringes and rubber plugs into the plugging box, first evacuating the inside of the plugging box, and then driving the lifting actuator through the lifting drive source to drive the plugging head to descend, thereby pressing the rubber plug into the syringe, a single operation can achieve the plugging operation of all syringes in the material rack, with a wide plugging area and high plugging efficiency.

[0004] The plugging device of some syringes fixes the syringe barrel and the plug by providing a material rack. However, in actual operation, considering that different specifications of syringes may be required during the use of the gel, the lengths and diameters of syringes of different specifications are different, and similar material racks do not have measures to be compatible with syringes of different specifications. As a result, the plugging device can only perform plugging operations on syringes of the same specification, which limits the practicability and scope of application of the device. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the prior art lacks the above-mentioned measures for being compatible with syringes of different specifications, resulting in the plugging device being able to perform plugging operations only on syringes of the same specification, and to propose a plugging device based on a gel syringe.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A plugging device based on a gel syringe comprises a processing table 1, a support frame 2 and a fixing seat 3 are fixedly installed on the top of the processing table 1, a pressing member 5 is fixedly installed on the support frame 2 through a driving member 4, and a bracket 7 for placing a syringe 6 is slidably connected to the end surface of the fixing seat 3;

[0022] Among them, the bracket 7 includes a base 71 and a top plate 72. The interior of the base 71 is provided with a fixing part 8 for fixing the syringe 6, and the base 71 is slidably connected to the top plate 72 through a locking part 9. The locking part 9 is used to adjust the height of the top plate 72 to adapt to syringes 6 of different specifications.

[0023] It is worth mentioning that a rubber pad is provided at the bottom of the clamping member 5 to prevent sliding with the injection rod 62 during compression, and a guide rod slidably connected to the support frame 2 is fixedly installed on the top thereof, and the guide rod is used to ensure that the clamping member 5 remains stable when sliding.

[0024] Furthermore, the driving member 4 is a cylinder 41, the support frame 2 is an L-shaped structure, and the cylinder 41 is fixedly installed on the top thereof, the axial end of the cylinder 41 is slidably connected to the support frame 2, and the clamping member 5 is fixedly installed thereon, and the clamping member 5 is used to compress the syringe 6, and the syringe 6 includes a syringe barrel 61 and an injection rod 62.

[0025] Furthermore, the fixing member 8 includes a U-shaped plate 81, the base 71 is an I-shaped structure, and a slide groove 82 is penetrated on one side of the top, the U-shaped plate 81 is slidably connected to the slide groove 82, and a first spring is fixedly connected between its side surface and the inner side surface of the slide groove 82, and the end surface of the base 71 and the two sides of the U-shaped plate 81 are respectively penetrated by a plurality of circular holes 83 and strip holes 84, the injection cylinder 61 is slidably connected in the circular hole 83 and the strip hole 84, and it can be tightened by the strip hole 84, and the end surface of the top plate 72 is provided with a plurality of sponge rings 723 through the circular hole 83, and the sponge ring 723 is used to cooperate with the strip hole 84 to fix the injection rod 62.

[0026] It is not difficult for a person skilled in the art to know that a pair of hanging ears are provided on the top of the conventional syringe 61, and the syringe 61 uses the pair of hanging ears to contact the top of the base 71 to achieve the effect of being inserted into the circular hole 83 and the strip hole 84, and then the circular hole 83 cooperates with the strip hole 84 to clamp the syringe 61 by pressing against the U-shaped plate 81, so as to achieve the purpose of being applicable to the syringe 61 of different diameters;

[0027] Among them, the sponge ring 723 can be used to fix the injection barrel 61 of different diameters. After the injection rod 62 is pressed into the injection barrel 61, the injection rod 62 uses the rubber plug to generate friction with the inner wall of the injection barrel 61 to prevent the injection rod 62 from rising with the top plate 72. The inner walls of the circular hole 83 and the strip hole 84 are both provided with elastic pads.

[0028] In more detail, the top plate 72 and the top of the base 71 are slidably connected via a sliding rod 73, and a second spring 74 is provided on the outer periphery of the sliding rod 73. Both ends of the second spring 74 are fixedly connected to the sides of the top plate 72 and the base 71, respectively, and a locking member 9 is provided at the bottom of one of the sliding rods 73.

[0029] It is worth mentioning that the use of the slide rod 73 and the second spring 74 can prevent the pressure applied by the clamping member 5 from being too large, thereby damaging the injection cylinder 61. On the other hand, by adjusting the length of the slide rod 73, the height of the top plate 72 can be changed, thereby facilitating the use of injection rods 62 of different lengths.

[0030] In general, the locking member 9 includes a cartridge 91 slidably connected to the bottom of one of the slide bars 73, and a plurality of slots 92 are provided on both sides of the bottom of the slide bar 73. The cartridge 91 is rotatably connected to two sides with claws 93 via a rotating seat 911. The claws 93 can be clamped into the slots 92, and a third spring 94 is fixedly connected between the side surfaces of the claws 93 and the side surfaces of the cartridge 91. A pair of the claws 93 can abut against the top of the base 71.

[0031] Specifically, under normal circumstances, the pair of claws 93 are clamped into the clamping groove 92 under the support of the third spring 94, so as to fix the clamping cylinder 91 and clamp the slide rod 73;

[0032] Among them, because the sliding rod 73 is locked, the height of the top plate 72 is fixed to achieve an adjustable effect. The advantage of this is that changing the height of the top plate 72 can adapt to the injection rods 62 of different lengths, and prevent the top plate 72 from being too high when the injection rod 62 is short, so that the injection rod 62 cannot be accurately pressed into the injection barrel 61;

[0033] Furthermore, because the claw 93 is in conflict with the base 71 , the second spring 74 will not affect the sliding of the top plate 72 , and will not affect the plugging operation of the injection rod 62 .

[0034] Finally, the side of the U-shaped plate 81 is provided with a protrusion 811 slidably connected to the slide groove 82, and the side of the top plate 72 is fixedly installed with a push rod 721, and one side of the push rod 721 is provided with a guiding slope 722, and the guiding slope 722 slides against the protrusion 811.

[0035] It is worth mentioning that, generally speaking, the larger the diameter of the conventional injection barrel 61 is, the longer the length of the injection rod 62 will be. If the diameter of the injection barrel 61 is large, the heights of the top plate 72 and the push rod 721 will be high. When the top plate 72 is pressed to slide downward, the push rod 721 will use the guide slope 722 to resist and push the U-shaped plate 81 to slide.

[0036] After the push rod 721 is separated from the protruding portion 811, the U-shaped plate 81 slides back to its original position under the action of the first spring, so that the syringe 61 loses its fixation and can be taken out.

[0037] Working mode: When working, press the pair of claws 93 to disengage them from the slot 92, and then press the top plate 72 to slide the slide bar 73. The pair of claws 93 are clamped into the slot 92 under the action of the third spring 94 to fix the height of the top plate 72;

[0038] Then, several injection cylinders 61 and injection rods 62 are respectively placed into the circular hole 83 and the sponge ring 723 at the top of the base 71, and then the bracket 7 is pushed under the pressing member 5, and the cylinder 41 drives the pressing member 5 to press the top plate 72;

[0039] Finally, during the plugging process, several injection rods 62 move downward under the drive of the top plate 72, and the top plate 72 also drives the push rod 721 to move so that the guiding slope 722 contacts and pushes the protrusion 811. Driven by the protrusion 811, the U-shaped plate 81 uses the strip hole 84 to cooperate with the circular hole 83 to fix the injection barrel 61, so as to facilitate the injection rod 62 to be inserted into the injection barrel 61.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
