DETAILED DESCRIPTION

[0032] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] like Figures 1 to 3 As shown, the utility model provides a glue injection box, including a body 1 and a support leg 2, wherein the body 1 has a plurality of first connection ends 11, a glue injection port 12, a glue injection cavity 13 and a connecting port 14, the glue injection cavity 13 is connected with the glue injection port 12, and is used to contain and inject glue, the first connection end 11 is connected with the glue injection cavity 13 through the connecting port 14, forming a connected internal space, so that the glue injection cavity 13 and the support leg 2 can be connected with each other. The support leg 2 is detachably connected with the first connection end 11, and the first connection end 11 has a first matching portion 111, and the support leg 2 has a second matching portion 21 adapted to the first matching portion 111, ensuring that the support leg 2 can be accurately docked with the first matching portion 111 of the first connection end 11 of the body 1 through the second matching portion 21, so as to be firmly connected, and realize the detachable connection of the support leg 2. The support leg 2 has a hollow structure, so that when the second matching part 21 is connected to the first matching part 111, the support leg 2 is connected to the connecting port 14 through the first connecting end 11 to form a continuous flow channel with the glue injection cavity 13, so that glue can flow from the glue injection port 12 into the glue injection cavity 13 and flow to the dialyzer through the support leg 2.

[0034] Based on the above structure, glue can flow from the glue injection port 12 into the glue injection cavity 13, and flow to the support leg 2 through the connecting port 14, and then flow to the dialyzer, which is detachably connected through the second matching portion 21 of the support leg 2 and the first matching portion 111 of the connecting end, so that after the amount of residual glue in the support leg 2 of the glue injection box reaches a certain level, a new support leg 2 can be replaced to avoid the problem that the glue separation structure cannot be used anymore due to excessive residual glue; at the same time, the detachable connection between the support leg 2 and the main body facilitates the staff to clean the residual glue in the main body or the support leg 2, thereby improving efficiency. In addition, the support leg 2 can be replaced to meet different dialyzer production requirements and match different dialyzer components.

[0035] It should be noted that the glue injection port 12 of the main body 1 is relatively large, which can facilitate manual glue cleaning and multiple reuses.

[0036] like Figure 7 or Figure 8 As shown, in some embodiments, the support leg 2 has a second connection end 22 sleeved on the first connection end 11, the second connection end 22 is a hollow structure, the second matching portion 21 is a first groove 235 structure surrounding the inner circumference of the second connection end 22, and when assembled with the first connection end 11, it can provide a space for receiving and fixing the first connection end 11, and correspondingly, the first matching portion 111 is a first protrusion structure surrounding the outer circumference of the first connection end 11, and the first protrusion structure is adapted to the first groove 235 structure, so that the first protrusion structure can be inserted into the first groove 235 structure on the inner circumference of the second connection end 22, thereby forming a stable, sealed or guided connection effect, thereby realizing the nested installation of the support leg 2 and the main body;

[0037] In this embodiment, another method can also be adopted: the second matching portion 21 is a second protrusion structure surrounding the inner circumference of the second connecting end 22, and the first matching portion 111 is a second groove 246 structure surrounding the outer circumference of the first connecting end 11, and the second protrusion structure is adapted to the second groove 246 structure.

[0038] Compared with the previous method, the second matching portion 21 is a protruding structure, and the first matching portion 111 is a groove structure accordingly. The second protruding structure and the second groove 246 structure are also matched with each other to ensure that the two are closely connected.

[0039] Read also Figure 5In some embodiments, the main body 1 further includes a box body 15, which has a diverter 16 to divide the glue injection cavity 13 into a plurality of sub-cavities 131, so that the glue injected into the glue injection cavity 13 can be distributed into each sub-cavity 131 to meet the needs of multi-point glue injection or simultaneous multi-directional or multi-component glue injection; a plurality of connecting ports 14 are opened on the periphery of the box body 15, and each connecting port 14 is arranged corresponding to a sub-cavity 131. The first connecting end 11 is arranged on the periphery of the box body 15 and is connected to the connecting port 14 to guide the glue from a specific sub-cavity 131 to the support leg 2, thereby realizing the glue injection operation on different positions or different components.

[0040] In some embodiments, the box body 15 and the first connecting end 11 are an integral structure formed by blow molding.

[0041] It is understandable that when producing the injection box, the blow molding process technology is used, so that the box body 15 and the first connection end 11 are directly made into an integral structure through a single blow molding operation, so that there is no seam or connection point between the box body 15 and the first connection end 11, which enhances the overall mechanical properties and durability of the injection box. In addition, integration reduces the gap caused by assembly, which helps to improve the sealing effect.

[0042] like Figure 4 As shown, in some embodiments, the box body 15 includes a bottom wall 151, a side wall 152 and a top wall 153, the bottom wall 151 and the top wall 153 are connected through the side wall 152, the bottom wall 151 serves as a basic support for the box body 15, the side wall 152 is a peripheral structure formed by extending upward from the bottom wall 151, and the top wall 153 is located at the top of the box body 15, and is tightly connected to the bottom wall 151 through the side wall 152, and the bottom wall 151, the side wall 152 and the top wall 153 enclose a glue injection cavity 13 for accommodating and controlling the flow of glue. It can be understood that the box body 15 in this embodiment is blow-molded, so the bottom wall 151, the side wall 152 and the top wall 153 are an integrated structure, and the connection between the side wall 152 and the top wall 153 in this embodiment is in an arc shape. When the glue injection box is in the centrifugal process, the arc shape and the top wall 153 are used to prevent the glue from being thrown out during the centrifugation process, thereby maintaining the stability of the glue injection process and avoiding glue waste.

[0043] Due to the limitations of the injection molding process, in terms of product structure, the purpose of heat-sealing the PE film is mainly to prevent the glue from being thrown out of the glue injection box due to the centrifugal force during the centrifugal process. Compared with the existing injection molding method, the box body 15 of this embodiment is optimized to blow molding. The connection between the side wall 152 and the top wall 153 is arc-shaped, so that no glue will be thrown out of the glue injection box during the centrifugal process.

[0044] It can be understood that the support leg 2 in this embodiment is also formed by blow molding, and the redundant sprue can be cut off by the sprue cutting equipment.

[0045] Read also Figure 6 In some embodiments, the diverter 16 includes a diverter body 161 located in the center and a diverter branch 162. The diverter branch 162 is arranged at intervals around the axis of the diverter body 161. One end of the diverter branch 162 is connected to the diverter body 161, and the other end of the diverter branch 162 extends to the inner wall of the box body 15, so that the glue injected into the glue injection cavity 13 can be effectively distributed to each diverter branch 162 and flow to each sub-cavity 131 through them. It can be understood that the two sides of the diverter branch 162 in this embodiment form a slope to facilitate the glue to flow to the sub-cavity 131, ensuring that the glue can flow from the glue injection port 12 and be dispersed into each diverter channel.

[0046] In addition, the first end surface 1621 of the flow dividing branch 162 facing the glue injection port 12 is substantially flush with the second end surface 1611 of the flow dividing body 161 facing the glue injection port 12 (eg, Figure 5 As shown), when the glue passes through the diversion body 161 and the diversion branch 162, no obstruction will be formed at the lowest point of the connecting port 14, ensuring that the glue can smoothly enter each sub-cavity 131 from the glue injection cavity 13, effectively avoiding the occurrence of glue accumulation or flow obstruction.

[0047] Read also Figure 7 In some embodiments, the support leg 2 includes multiple first support legs 23 and multiple second support legs 24, the length of the first support legs 23 is longer than the length of the second support legs 24, the multiple first support legs 23 are spaced apart around the axis of the main body 1, the multiple second support legs 24 are spaced apart around the axis of the main body 1, and the first support legs 23 and the second support legs 24 are spaced apart.

[0048] It can be understood that in the centrifugal process of this embodiment, two dialyzers will be centrifugally injected with glue at the same time. The dialyzers will be placed one above the other in a cross-shaped manner. The first leg 23 is assembled with the dialyzer at the bottom, and the second leg 24 is assembled with the dialyzer at the top to match the dialyzer assembly.

[0049] In some embodiments, the first support leg 23 includes a first section 231 and a second section 232, the first section 231 is connected to the second section 232, and the end of the first section 231 away from the connection with the second section 232 is connected to the second connection end 22, the first section 231 is used to dock with the main body 1, and the second section 232 provides height support; the second support leg 24 includes a third section 241, a fourth section 242 and a fifth section 243, the third section 241, the fourth section 242 and the fifth section 243 are connected in sequence to form a support structure with multiple sections, and the end of the third section 241 away from the connection with the fourth section 242 is connected to the second connection end 22, the third section 241 is used to dock with the main body 1, and the fourth section 242 and the fifth section 243 provide height support.

[0050] In some embodiments, a first reinforcing rib 233 is provided between the first section 231 and the second section 232 to enhance the mechanical strength and stability of the connection portion, prevent breakage or deformation when bearing pressure, torsion or impact, so as to improve the overall rigidity and durability of the entire support leg 2 and even the injection box, ensure stability and safety during the injection process, and extend the service life of the injection box. In addition, the fourth section 242 adopts a curved structure at the portion connected to the third section 241 to increase the flexibility of the support leg 2, and at the same time, as a stress release point, reduce stress concentration at the right-angle connection, and enhance the durability and stability of the overall structure.

[0051] In some embodiments, the outer periphery of the second segment 232 has a plurality of first protrusions 234 and a plurality of first grooves 235 .

[0052] The multiple first protrusions 234 in this embodiment can increase the friction force, so that during installation or use, the friction between the first leg 23 and the inner wall of the dialyzer liquid port can provide a better anti-slip effect. The multiple first grooves 235 serve as exhaust grooves. After the glue is injected, the glue reacts and generates heat. During the glue reaction, the generated gas and heat are discharged through the first grooves 235.

[0053] In addition, the outer circumference of the fifth segment 243 has a plurality of second protrusions 245 and a plurality of second grooves 246 .

[0054] The multiple second protrusions 245 in this embodiment can increase the friction force, so that during installation or use, the friction between the second leg 24 and the inner wall of the dialyzer liquid port can provide a better anti-slip effect. The multiple second grooves 246 serve as exhaust grooves. After the glue is injected, the glue reacts and generates heat. The gas and heat generated during the glue reaction are discharged through the second grooves 246.

[0055] In summary, the embodiment of the utility model provides a glue injection box with a single structure and no interference. If any assembly part has a problem during the manufacturing process, it can be replaced with a new one without causing the entire product to be scrapped. The glue cleaning is convenient, which can effectively increase the number of times the product is reused. At the same time, it can be applied to dialyzers of different specifications and sizes. When using an extended dialyzer, it only needs to replace the long and short legs of the glue injection box of the corresponding specifications to resume normal production.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
