It also makes it easier to take them out. However, existing two-component mixing delivery devices do not have support devices and require the use of other items for auxiliary support, which is extremely inconvenient to use.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] A typical implementation of the present invention is as follows: Figure 1 and Figure 8 As shown, a two-component mixed liquid delivery device includes a syringe 3. Two syringes 3 are provided and placed side by side. The syringe 3 is a common syringe on the market, including an outer sleeve 301 and a push rod 302. The outer sleeve 301 is sleeved on the outside of the push rod 302. A piston is provided at one end of the push rod 302, and a power assist plate 303 is provided at the other end. The power assist plates 303 on the two syringes 3 are connected through a push plate frame 1.

[0030] Specifically, such as Figure 2 As shown, the push plate frame 1 includes a top plate 101 and a limit plate 102. There are two limit plates 102. The two limit plates 102 are arranged side by side and at a set distance. The two limit plates 102 are arranged parallel to the top plate 101. The bottom of the top plate 101 is connected to the bottom of the two limit plates 102 through a first connecting plate. A limit groove 103 is formed between the top plate 101 and the two limit plates 102. The thickness of the limit groove 103 is adapted to the thickness of the power-assisting plate 303, so that the power-assisting plate 303 can be placed in the limit groove 103. The limit plate 102 is tilted toward the side of the top plate 101 at a set angle so as to clamp the power-assisting plate 303 placed in the limit groove 103.

[0031] A U-shaped hole 104 is provided in the middle of the limiting plate 102 , and the top of the U-shaped hole 104 is open. When the assisting plate 303 is placed in the limiting groove 103 , the push rod 302 can be placed in the U-shaped hole 104 from the top, thereby facilitating the fixation of the assisting plate 303 .

[0032] A buckle 105 is provided on the top of one side of the top plate 101 facing the limiting plate 102. There are two buckles 105, and the two buckles 105 are arranged opposite to the U-shaped holes 104 of the two limiting plates 102. When the two assisting plates 303 are placed in the limiting grooves 103, the assisting plates 303 are limited by the buckles 105 to prevent the assisting plates 303 from escaping from the limiting grooves 103.

[0033] A side surface of the top plate 101 away from the limiting plate 102 is provided with anti-slip grooves.

[0034] One end of the outer sleeve 301 is provided with a hanging ear 304, and the hanging ears 304 on the two syringes 3 are fixedly connected by the fixing bracket 2. Specifically, Figure 3 and Figure 4 Two grooves 201 are provided in the middle of the fixed bracket 2. The grooves 201 are C-shaped. The two grooves 201 are arranged side by side and at a set distance. The outer sleeves 301 on the two syringes 3 can be respectively snapped into the two grooves 201 of the fixed bracket 2, thereby fixing the two syringes 3.

[0035] A fixing plate 204 is provided on one side of the fixing bracket 2, and the fixing plate 204 is located between the two grooves 201. The top of the fixing plate 204 is connected to the fixing bracket 2 through a second connecting plate. The fixing plate 204 and the fixing bracket 2 are spaced a set distance apart, so that a fixing groove 205 is formed between the fixing plate 204 and the fixing bracket 2. The fixing groove 205 is adapted to the hanging ear 304 on the syringe 3, and the hanging ear 304 on the syringe 3 can be stuck in the fixing groove 205, and the hanging ear 304 on the syringe 3 can rotate in the fixing groove 205 along the axis of the syringe 3.

[0036] The first push-pull handle 202 is symmetrically arranged on the left and right sides of the fixed bracket 2, and the second push-pull handle 203 is symmetrically arranged on the upper and lower sides of the fixed bracket 2. The first push-pull handle 202 and the second push-pull handle 203 are both in an inner arc structure on the side away from the fixed plate 204, which is convenient for buckling the syringe 3 when injecting.

[0037] The outer sleeve 301 of the two syringes 3 is provided with an injection port 305 at one end away from the ear 304. Figure 7 As shown, the injection port 305 is connected to the liquid inlet end of the tee 5 through a Luer connector 502, and the liquid outlet end of the tee 5 is provided with a quick fixing connector 503. The tee 5 is fixedly connected to the mixing head 6 through the thread on the quick fixing connector 503, and the other end of the mixing head 6 is connected to the Luer thread head 7.

[0038] A one-way clamping ring 504 is provided at one end of the mixing head 6 close to the Luer thread head 7. The Luer thread head 7 is clamped to the mixing head 6 through the one-way clamping ring 504, so that the Luer thread head 7 can rotate freely around the axis of the mixing head 6 after being clamped.

[0039] The three-way pipe 5 is also rotatably connected to the support base 4, and the support base 4 is connected to the three-way pipe 5 through the circular slot 401 and the fixing column 501. Specifically, Figure 5 and Figure 6 The support seat 4 includes a bottom plate 406 and a support plate 407 . There are two support plates 407 . The two support plates 407 are respectively located on both sides of the bottom plate 406 and are vertically arranged with respect to the bottom plate 406 .

[0040] A circular slot 401 is provided at one end of the support plate 407, and the arc angle of the circular slot 401 is 270~285 degrees. An opening is provided on one side of the circular slot 401, and fixing columns 501 are provided on both sides of the tee pipe 5. The two fixing columns 501 are respectively provided corresponding to the two circular slots 401, and the fixing columns 501 can enter the circular slot 401 from the opening of the circular slot 401. A triangular guide hole 402 is provided at the opening of the circular slot 401, which is convenient for clamping the fixing column 501 in the circular slot 401, thereby realizing the rotational connection between the support seat 4 and the tee pipe 5, so that the support seat 4 can be closed and opened.

[0041] An arc groove 408 is provided on the upper surface of the bottom plate 406. There are two arc grooves 408, which are arranged side by side. The arc groove 408 is adapted to the outer wall of the outer sleeve 301 of the syringe 3. When the bottom plate 406 is parallel to the axis of the syringe 3, that is, when the support seat 4 is closed, the outer sleeve 301 can be placed in the arc groove 408, so that the bottom plate 406 and the outer sleeve 301 are fitted together. Support platforms 404 are provided on both sides of the upper surface of the bottom plate 406 near one end of the circular slot 401. When the support seat 4 is closed, the three-way pipe 5 can be supported by the support platform 404. A contoured buckle 403 is provided on the top of the support plate 407. When the support seat 4 is closed, the contoured buckle 403 can be engaged with the outer wall of the outer sleeve 301, so that the support seat 4 is fixed by the contoured buckle 403 to prevent the support seat 4 from rotating, which is convenient for the staff to use.

[0042] A limiting surface 405 is provided on one end face of the bottom plate 406 close to the support platform 404. When the bottom plate 406 is perpendicular to the axis of the syringe 3, that is, when the support seat 4 is opened, the limiting surface 405 contacts the three-way pipe 5, thereby limiting the rotation angle of the support seat 4, and then utilizing the support seat 4 to support the two-component mixed liquid delivery device. The support angle is 20 degrees, which is convenient for the staff to take.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
