Description

Technical Field

[0001] The utility model relates to the technical field of injection molding syringes, in particular to a double-color injection molding light-proof injection molding syringe. Background Art

[0002] The syringe is a common medical device. As early as the 15th century, the Italian Catinel proposed the principle of the syringe. The needle is mainly used to extract or inject gas or liquid. The syringe can also be used in medical equipment and containers, such as some scientific instruments in chromatography, for injection through rubber diaphragms. In clinical nursing work, the syringe is the most commonly used medical tool, which is used to safely inject liquid medicine into the body.

[0003] However, the syringes currently used for clinical injections do not have a light-shielding function, and many liquid medicines need to be protected from light. Clinically, only light-shielding paper can be used on the outside of the syringes. However, after adding the light-shielding paper, there is no way to observe the use of the liquid medicine.

[0004] Therefore, it is particularly important to design a novel two-color injection molding light-proof injection molding syringe to solve the above-mentioned technical defects and improve the practicality of the overall two-color injection molding light-proof injection molding syringe. Utility Model Content

At the same time, when the connecting component drives the piston to absorb the injection molding material, it can simultaneously drive the shading cloth to move, and block the shading cloth on the outside of the syringe body. The shading cloth plays a shading role for the injection molding material in the syringe body. When the injection molding material is extruded during injection molding, the shading cloth can be driven to descend, which is convenient for the user to check the injection molding measurement, so as to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] A two-color injection light-shielding injection syringe comprises a connecting frame 1, a positioning frame 2 is arranged on the top of the connecting frame 1, two groups of syringe bodies 4 are connected to the connecting frame 1 through a connecting component 3, and light shielding components 5 are arranged on both the front and rear sides of the connecting frame 1;

[0027] Among them, pistons 401 are slidably connected inside the two groups of syringe bodies 4 and at the bottom of the two groups of lifting blocks 302. The two groups of pistons 401 are connected to the two groups of lifting blocks 302 in a fixed manner. The outer sides of the two groups of syringe bodies 4 are marked with scales 402, and the bottoms of the two groups of syringe bodies 4 are fixedly connected with injection heads 403.

[0028] Specifically, first, the syringe body 4 sucks the injection molding raw material, pulls the connecting component 3 outward, and then pulls the pistons 401 in the two groups of syringe bodies 4 through the connecting component 3. At this time, the connecting frame 1 plays a limiting and fixing role for the two groups of syringe bodies 4, and the injection molding raw material is sucked into the syringe body 4 through the injection head 403 through the piston 401. The scale 402 can accurately display the scale of the injection molding raw material. At the same time, the connecting component 3 can drive the shading component 5 to rise and fall when it is raised and lowered, and then the shading component 5 plays a shading role on the syringe body 4.

[0029] Also, see Figure 1-Figure 3 , the connecting frame 1 is connected with two sets of syringe bodies 4 through a connecting assembly 3;

[0030] The connecting assembly 3 is used for synchronous connection between two sets of syringe bodies 4. The specific structure of the connecting assembly 3 is as follows:

[0031] The connecting component 3 includes two groups of sliding columns 301, a lifting block 302, a pull ring 303, a connecting ring 304 and a sliding groove 305. The two groups of sliding columns 301 are respectively fixedly connected to the left and right sides of the connecting frame 1. The lifting blocks 302 are slidably connected between the two groups of sliding columns 301 and above the two groups of syringe bodies 4. The pull ring 303 is fixedly connected to the top of the two groups of lifting blocks 302. The connecting ring 304 is slidably connected between the two groups of sliding columns 301 and on the outside of the two groups of syringe bodies 4. Sliding grooves 305 are provided on the inner sides of the two groups of sliding columns 301 and at the corresponding positions of the two groups of lifting blocks 302. Slide blocks are fixedly connected to the two groups of lifting blocks 302 and the outside of the connecting ring 304 and at the corresponding positions of the sliding grooves 305.

[0032] Specifically, the piston 401 is driven to move through the connecting component 3, the pull ring 303 is pulled upward, and the lifting block 302 is pulled through the pull ring 303, so that the lifting block 302 moves in the sliding groove 305 between the two groups of sliding columns 301, and the lifting block 302 drives the piston 401 to move in the syringe body 4 when moving, and then the injection molding material is sucked into the syringe body 4 from the injection head 403 through the piston 401. During injection molding, the lifting block 302 is pressed downward, so that the lifting block 302 moves between the two groups of sliding columns 301, and then the piston 401 is pressed by the lifting block 302, and the injection molding material in the piston 401 is squeezed out through the injection head 403.

[0033] Then, see Figure 1 , Figure 2 as well as Figure 4 , both the front and rear sides of the connecting frame 1 are provided with a shading component 5;

[0034] The shading component 5 is used to shield the syringe body 4 from light. The specific structure of the shading component 5 is as follows:

[0035] The shading assembly 5 includes a support plate 501, a winding seat 502, a winding roller 503, a connecting belt 504, a dividing belt 505 and a shading cloth 506. The support plate 501 is fixedly connected to the bottom of the front side of the connecting frame 1, the top of the support plate 501 is fixedly connected to the winding seat 502, the internal rotation of the winding seat 502 is connected to the winding roller 503, two groups of connecting belts 504 are provided between the winding roller 503 and the connecting ring 304, the dividing belt 505 is fixedly connected between the two groups of connecting belts 504, and the shading cloth 506 is fixedly connected between the two groups of connecting belts 504 and below the dividing belt 505.

[0036] Specifically, when the connecting component 3 drives the piston 401 to move downward, the injection molding material is squeezed out of the syringe body 4, and the connecting belt 504 is driven to move at the same time, and then the dividing belt 505 and the blackout cloth 506 are driven to move through the connecting belt 504, and the blackout cloth 506 is moved away from the outside of the syringe body 4, thereby eliminating the blackout cloth 506 from blocking the syringe body 4. At this time, the scale 402 on the surface of the syringe body 4 can be used to accurately check the measurement of the extruded injection molding material. When the injection molding material is sucked into the interior of the syringe body 4 through the connecting component 3, the connecting component 3 drives the connecting belt 504 to move, and then the blackout cloth 506 is pulled out from the winding roller 503 in the winding seat 502 through the connecting belt 504, so that the blackout cloth 506 has a blackout effect on the syringe body 4.

[0037] In this embodiment, the implementation scenario is specifically as follows: in actual use, the syringe body 4 is first sucked into the injection molding raw material, the connecting component 3 is pulled outward, and then the pistons 401 in the two groups of syringe bodies 4 are pulled through the connecting component 3. At this time, the connecting frame 1 plays a limiting and fixing role for the two groups of syringe bodies 4, and the injection molding raw material is sucked into the syringe body 4 through the injection head 403 through the piston 401. The scale 402 can accurately display the scale of the injection molding raw material. At the same time, the connecting component 3 can drive the shading component 5 to rise and fall when it is raised and lowered, and then the shading component 5 plays a shading role on the syringe body 4. Compared with the existing injection molding syringes, the utility model can improve the overall practicality of the injection molding syringe through design.
