[0002] Before creating a dental denture, the patient's teeth must be imaged and the occlusal relationship of the upper and lower teeth determined. This process typically involves two impressions: the first impression is made with a heavy elastomeric impression material, typically mixed by hand. The mixed material is then placed on an impression tray and the patient bites down. The second impression is made with a light elastomeric impression material, typically using an impression material mixer connected to a two-component impression material cartridge, followed by injection. The patient then bites down again to obtain the final, accurate dental image.

DETAILED DESCRIPTION

[0027] One of the core points of the present invention is to provide a material cartridge connecting chuck for a mixer, so as to save materials and reduce the use cost of the mixer.

[0028] Another core of the present invention is to provide a mixer based on the above-mentioned material cartridge connecting chuck for the mixer.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , Figure 1 This is an axonometric view of a material cartridge connecting chuck for a mixer provided by an embodiment of the present invention. Figure 2 A top view of a material cartridge connecting chuck for a mixer provided in an embodiment of the present invention, Figure 3 An axonometric diagram of a mixer provided by an embodiment of the present invention, Figure 5 A cross-sectional view of a material cartridge according to an embodiment of the present invention.

[0031] The embodiment of the present invention provides a material barrel connecting chuck 1 for a mixer, which is used to connect the material barrel 3 and the mixer 2. The material barrel connecting chuck 1 for the mixer includes a chuck body 101. The chuck body 101 is annular as a whole, so that it can be sleeved on the outlet pipe 301 of the material barrel 3. A first axial limiting connector and a second axial limiting connector are provided on the chuck body 101. After the chuck body 101 rotates around the outlet pipe 301 of the material barrel 3 through a preset angle, the first axial limiting connector can cooperate with the first axial limiting fitting on the material barrel 3, and the second axial limiting fitting can cooperate with the first axial limiting fitting on the material barrel 3. The second axial limit connecting piece can cooperate with the second axial limit fitting piece on the mixer 2 to press the inlet pipe 203 of the mixer 2 and the outlet pipe 301 of the material cylinder 3. One of the above-mentioned first axial limit connecting piece and the first axial limit fitting piece can be a convex structure, and the other can be a groove structure. The two gradually cooperate with each other as the chuck body 101 rotates. The second axial limit connecting piece and the second axial limit fitting piece can adopt a concave-convex fitting structure similar to the first axial limit connecting piece and the first axial limit fitting piece.

[0032] To sum up, compared with the prior art, the material cylinder connecting chuck 1 for the mixer provided in the embodiment of the present invention is used by putting the chuck body 101 on the outside of the outlet pipe 301 of the material cylinder 3, and then plugging the mixer 2 into the outlet pipe 301 of the material cylinder 3. Alternatively, the mixer 2 can be plugged into the outlet pipe 301 of the material cylinder 3 first, and then the chuck body 101 can be put on the outside of the outlet pipe 301 of the material cylinder 3. Then, the chuck body 101 is rotated to make the first axial limit connecting piece cooperate with the first axial limit fitting piece, and the second axial limit connecting piece cooperate with the second axial limit fitting piece to realize the installation of the mixer 2. After use, the chuck body 101 is rotated in the opposite direction to the initial position and the mixer 2 is replaced. The chuck body 101 is reusable and does not need to be replaced, which helps to save materials and reduce the use cost of the mixer 2.

[0033] Preferably, one of the first axial limiting connector and the first axial limiting fitting includes a plurality of limiting steps 102 evenly spaced circumferentially, and the other of the first axial limiting connector and the first axial limiting fitting includes a plurality of matching step grooves 302 evenly spaced circumferentially. After the chuck body 101 rotates relative to the material barrel 3 by a preset angle, at least two limiting steps 102 are matched with the matching step grooves 302 in a one-to-one corresponding manner. Specifically, as Figure 1 and Figure 2 As shown, there are two limiting steps 102, which are arranged on the outer wall of the chuck body 101, and the two limiting steps 102 are symmetrical about the central axis of the chuck body 101. Correspondingly, the material cylinder 3 is provided with the above-mentioned matching step groove 302. It should be noted that the number of limiting bosses can be the same as the number of matching step grooves 302. Figure 1 and Figure 5 The two limiting bosses and two matching step grooves 302 shown can also make the number of limiting bosses greater than the matching step grooves 302, that is, use more than two even number of limiting bosses and two matching step grooves 302. In this way, as the chuck body 101 rotates, the various limiting bosses on the chuck body 101 can periodically cooperate with the matching step grooves 302 on the material barrel 3.

[0034] Preferably, if Figure 1 、 Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the second axial limiting connecting member includes a plurality of limiting clamping platforms 107 uniformly distributed circumferentially on the inner wall of the clamping head body 101, and the second axial limiting matching member includes a plurality of first limiting buckles 204 circumferentially arranged on the mixer 2. After the clamping head body 101 and the mixer 2 are rotated relative to each other through a preset angle, the limiting clamping platforms 107 cooperate with the first limiting buckles 204 to axially limit the mixer 2.

[0035] Of course, in other embodiments, other matching methods can also be adopted between the second axial limiting connection piece and the second axial limiting fitting piece. One of the second axial limiting connection piece and the second axial limiting fitting piece can be an L-shaped groove, and the other of the second axial limiting connection piece and the second axial limiting fitting piece can be a clamping protrusion. The L-shaped groove has an opening for the clamping protrusion to enter and exit along the axial section of the clamp body 101 or the mixer 2. In this way, during assembly, the clamping protrusion can be aligned with the opening of the L-shaped groove first, and then the mixer 2 can be pressed down to the extreme position relative to the clamp body 101, and then the clamp body 101 can be rotated.

[0036] Alternatively, one of the second axial limit connecting member and the second axial limit fitting member can be a boss, and a groove with two ends open is provided on the boss along the circumferential direction, forming an avoidance space between two adjacent bosses, and the other one of the second axial limit connecting member and the second axial limit fitting member can be a protrusion that cooperates with the groove.

[0037] It should be noted that the matching structure between the first axial limit connecting part and the first axial limit fitting part and between the second axial limit connecting part and the second axial limit fitting part is not limited to the above embodiments. Those skilled in the art can design it according to their needs and it is not limited here.

[0038] As a preferred embodiment, in order to avoid the separation of the limiting step 102 and the matching step groove 302 during use, in the embodiment of the present utility model, as shown in FIG. Figure 1 and Figure 2 As shown, at least one mating surface of the limiting step 102 and the mating step groove 302 is respectively provided with mutually cooperating anti-slip teeth 104 and anti-slip tooth 104 grooves. In this way, when the limiting step 102 and the mating step groove 302 are mated in place, the anti-slip teeth 104 and the anti-slip tooth 104 grooves engage with each other to limit the limiting step 102 and the mating step groove 302 to prevent the two from accidentally detaching. When the two need to be separated, the anti-slip teeth 104 and the anti-slip tooth 104 groove can be forced to detach by applying a certain external force.

[0039] Further optimize the above technical solutions, such as Figure 1 As shown, one of the upper surface of the limiting step 102 and the inner top surface of the matching step groove 302 is a slope 103. The slope 103 is used to cooperate with the other of the upper surface of the limiting step 102 and the inner top surface of the matching step groove 302 when the limiting step 102 turns into the matching step groove 302 to press the chuck body 101 downward, so that the chuck body 101 has a downward tendency to press the mixer 2 onto the outlet pipe 301 of the material barrel 3.

[0040] Preferably, if Figure 1 As shown, a limit stop 105 is provided at the rear end of the limit step 102 and / or the rear end of the matching step groove 302. The limit stop 105 is used to prevent the chuck body 101 from continuing to rotate after the limit step 102 and the matching step groove 302 are in place.

[0041] Furthermore, the limiting stopper 105 at the rear end of the limiting step 102 extends along the axial direction of the chuck body 101 to form a rotation force-applying structure, which facilitates the user to apply force when rotating the chuck body 101 .

[0042] Preferably, the chuck body 101 is provided with an anti-slip limiter, which is used to cooperate with the anti-slip fitting on the material barrel 3 to prevent the chuck body 101 from being detached from the material barrel 3 when the first axial limiting connector is detached from the first axial limiting fitting.

[0043] Furthermore, one of the anti-slip limiter and the anti-slip mating member is a limit ring plate 106, and the other is a limit groove. The limit ring plate 106 cooperates with the limit groove to prevent the chuck body 101 from being detached from the material cylinder 3. Figure 1 As shown, the limiting ring plate 106 is provided on the chuck body 101, and the limiting groove is provided on the material cylinder 3. In this case, the limiting groove and the matching step groove 302 as the first axial limiting matching part mentioned above have the same structure.

[0044] To facilitate user operation, Figure 1 As shown, anti-slip grooves are provided on the outer wall of the chuck body 101 .

[0045] See also Figure 3 and Figure 4 The embodiment of the present invention also provides a mixer 2 for cooperating with the material barrel connecting clamp 1 for the mixer as described in any one of the above items, wherein the mixer 2 includes an outer tube body 201, a connecting sleeve 202 and a spiral rod 205, wherein one side of the connecting sleeve 202 is provided with an inlet pipe 203 that is plugged into and cooperates with the outlet pipe 301 of the material barrel 3, the inlet pipe 203 is inserted into the outlet pipe 301 of the material barrel 3, the other side of the connecting sleeve 202 is connected to the spiral rod 205, and the spiral rod 205 is inserted into the inner cavity of the outer tube body 201, and the connecting sleeve 202 and the outer tube body 201 are snap-fitted to limit the axial position of the connecting sleeve 202 and the outer tube body 201 relative to each other and are rotatably connected, and a second axial limiting fitting part of the mixer for cooperating with the second axial limiting connector is provided on the outer tube body 201.

[0046] By providing such a mixer 2 that can rotate relatively inside and outside, the mixer 2 can be installed without the first axial limiting connection piece on the chuck body 101 and the first axial limiting fitting piece on the material barrel 3 being separated. The chuck body 101 and the material barrel 3 can be firmly assembled first and then the mixer 2 can be assembled.

[0047] The clamping structure between the connecting sleeve 202 and the outer tube body 201 includes an upper annular boss 206 arranged on the mating surface of the connecting sleeve 202 and the outer tube body 201, and an annular groove arranged on the other. The connecting sleeve 202 and the outer tube body 201 are rotatably matched through the cooperation between the annular boss 206 and the annular groove, and the two are axially limited at the same time.

[0048] The connecting sleeve 202 is provided with two inlet tubes 203, and the outlets of the two inlet tubes 203 are respectively connected to the spiral conveying cavity formed between the spiral rod 205 and the outer tube body 201, so that the two-component materials can produce diversion, cross-mixing and reverse vortex therein, and the two agents can be stirred quickly and evenly, and then output through the outlet of the impression material syringe after instant mixing.
