DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] See also Figures 1 to 8 Now, a mixing device with an automatic locking and unlocking mechanism provided by the present invention is described. A mixing device with an automatic locking and unlocking mechanism includes a fixed base 100 and a barrel body 500.

[0031] The fixed base 100 has an upwardly opening accommodating cavity, a fixed column 200 is provided at the bottom of the accommodating cavity, the fixed column 200 includes a first column 210 and a second column 220 coaxially arranged from top to bottom, the diameter of the first column 210 is smaller than the diameter of the second column 220, a plurality of positioning grooves 230 are circumferentially provided on the upper part of the outer wall of the first column 210, the positioning grooves 230 are opened in the radial direction, a movable sleeve 300 is sleeved on the lower part of the first column 210, an elastic component 400 that is telescopic along the axial direction of the fixed column 200 is provided on the outer side of the fixed column 200, and the top end of the elastic component 400 is higher than the top end of the fixed column 200;

[0032] The barrel body 500 is inserted into the accommodating cavity, and an avoidance hole corresponding to the fixing column 200 is opened at the bottom of the barrel body 500. A plurality of elastic clips 600 corresponding to the positioning grooves 230 are circumferentially arranged on the inner side wall of the avoidance hole. The end of the elastic clip 600 is located in the avoidance hole, and an outward-inclined guide inclined surface 621 is arranged from top to bottom.

[0033] The barrel body 500 contains materials, and a barrel mouth sleeve is circumferentially arranged on the top of the outer wall of the barrel body 500 to facilitate sealing of the barrel body 500. The fixed base 100 is installed on the mixing equipment.

[0034] Specific reference Figure 5 and Figure 6Before performing the mixing operation, the barrel body 500 is inserted from top to bottom into the accommodating cavity in the fixed base 100. During the downward movement of the barrel body 500, the elastic component 400 is gradually compressed. At the same time, the upper end of the fixed column 200 gradually penetrates into the avoidance hole. The ends of multiple elastic clips 600 are blocked by the fixed column 200 and gradually contract radially with the help of their guide inclined surfaces 621 until the fixed column 200 moves to a position where the elastic clips 600 are opposite to the positioning groove 230. Multiple elastic clips 600 pop out radially at the same time with the help of their own elastic force and are stuck in the corresponding positioning grooves 230, thereby fixing the barrel body 500 on the fixed base 100. At this time, the barrel body 500 and the fixed base 100 can achieve radial and axial positioning, and the two remain relatively stable. The mixing equipment drives the barrel body 500 to rotate through the fixed base 100 to achieve the mixing operation.

[0035] Specific reference Figure 7 and Figure 8 After completing the mixing operation, continue to press the barrel body 500 downward. During the downward movement of the barrel body 500, the elastic component 400 continues to be compressed, and the multiple elastic clips 600 continue to shrink and slide out of the positioning groove 230 with the help of the guide slope 621, until the barrel body 500 moves to the position where the multiple elastic clips 600 are opposite to the movable sleeve 300. Since the outer diameter of the first column 210 is smaller than the outer diameter of the second column 220, a step is formed at the bottom of the first column 210, and the barrel body 500 continues to move downward, while the movable sleeve 300 cannot move downward under the limitation of the above-mentioned step, so that the multiple elastic clips 600 continue to be compressed with the help of the guide slope 621 until the ends of the multiple elastic clips 600 simultaneously abut against the circumference of the movable sleeve 300. Afterwards, the external force applied downward to the barrel body 500 is removed, and the barrel body 500 moves upward under the action of the elastic component 400. At this time, the movable sleeve 300 moves upward synchronously under the clamping action of multiple elastic clips 600. The movable sleeve 300 will block the positioning groove 230 during the upward movement, so that the barrel body 500 can be smoothly removed from the accommodating cavity of the fixed base 100.

[0036] The mixing device provided by the present invention with an automatic locking and unlocking mechanism realizes automatic locking of the barrel body 500 and the fixed base 100 by pressing the barrel body 500 to position it in the fixed base 100. The barrel body 500 and the fixed base 100 are automatically unlocked by pressing the barrel body 500 again and then removing the external force. The locking and unlocking operations of the barrel body 500 and the fixed base 100 are simple and convenient to apply force.

[0037] In some embodiments, see Figure 4 A pressure cover 240 is disposed on the top of the first column 210 , and the outer diameter of the pressure cover 240 is larger than the outer diameter of the first column 210 and smaller than the outer diameter of the movable sleeve 300 .

[0038] Specifically, a threaded hole is provided at the top of the first column 210 of the fixing column 200, and a mounting hole is provided on the pressure cover 240. Screws are used to penetrate the mounting hole from top to bottom and are threadedly connected to the upper part of the first column 210, thereby fixing the pressure cover 240.

[0039] Since the outer diameter of the pressure cap 240 is larger than the outer diameter of the first column 210 and smaller than the outer diameter of the movable sleeve 300 , it can be ensured that the movable sleeve 300 will not fall out of the first column 210 , and the end of the elastic clamp 600 can fall out of the pressure cap 240 .

[0040] Preferably, the outer wall of the movable sleeve 300 is inclined outward from bottom to top, and when the movable sleeve 300 moves upward to the lower end of the gland 240 and remains stable, the end of the elastic clamp 600 can smoothly escape along the outer wall of the movable sleeve 300. The outer wall of the gland 240 is inclined outward from top to bottom, and the outer diameter of the bottom of the gland 240 is smaller than the outer diameter of the top of the movable sleeve 300. After the end of the elastic clamp 600 escapes along the outer wall of the movable sleeve 300, it can smoothly escape along the outer wall of the gland 240.

[0041] In some embodiments, see Figure 4 A mounting groove is provided at the bottom of the accommodating cavity, and a plug-in block 250 is provided at the lower end of the fixing column 200. The plug-in block 250 is inserted into the mounting groove and fixed by screws passing from bottom to top; the pressure cover 240 is fixed to the top of the fixing column 200 by screws passing through the pressure cover 240 from top to bottom.

[0042] Specifically, a threaded hole is provided at the bottom of the plug-in block 250, and a corresponding through hole is provided at the bottom of the accommodating cavity. When the plug-in block 250 is inserted into the installation slot, a screw is used to penetrate the through hole from bottom to top to thread the plug-in block 250, so that the fixing column 200 is stably installed at the bottom of the accommodating cavity.

[0043] In some embodiments, see Figure 2 and Figure 4 The elastic component 400 includes a top cover 410 and a plurality of elastic members 420. The top cover 410 is arranged above the fixed column 200, and a avoidance hole for the fixed column 200 to pass through is opened in the middle. The plurality of elastic members 420 are longitudinally arranged in the circumference of the fixed column 200. The lower end of the elastic member 420 is connected to the bottom of the accommodating cavity, and the upper end is connected to the top cover 410, which is used to support and provide an upward elastic force to the top cover 410.

[0044] Specifically, a through hole is provided in the middle of the top cover 410, and the top cover 410 does not interfere with the fixed column 200 when it is raised or lowered. There are multiple elastic members 420, which are evenly arranged on the periphery of the fixed column 200. The elastic members 420 are arranged longitudinally, and their upper ends are connected to the top cover 410, and their lower ends are connected to the bottom of the accommodating cavity to provide longitudinal elastic force. When the elastic member 420 is not stressed, the top cover 410 is supported by the elastic force of the elastic member 420 and is located above the fixed column 200.

[0045] After the barrel body 500 is inserted into the accommodating cavity of the fixed base 100, it first contacts the top cover 410, and the barrel body 500 continues to press down, the elastic member 420 contracts, and the barrel body 500 presses down the top cover 410 until the fixed column 200 penetrates into the through hole of the top cover 410. In this process, the pressure cover 240 always provides an upward elastic force for the barrel body 500 with the help of the elastic member 420. When the barrel body 500 no longer applies external force, the elastic force of the top cover 410 can be used to realize the automatic unlocking of the barrel body 500.

[0046] In some embodiments, see Figure 4 The elastic member 420 includes a first spring 421, a guide rod 422 is inserted into the first spring 421, the upper end of the guide rod 422 is connected to the top cover 410, and the lower end of the guide rod 422 is inserted into a through hole opened at the bottom of the accommodating cavity.

[0047] Specifically, a retaining ring is further provided on the upper part of the guide rod 422. When the upper end of the guide rod 422 is inserted into the top cover 410, the retaining ring can prevent the guide rod 422 from continuing to move upward. The lower end of the guide rod 422 is inserted into the through hole opened at the bottom of the accommodating cavity, so that the guide rod 422 can move up and down along the through hole. The first spring 421 is sleeved on the outside of the guide rod 422, with the upper end abutting against the retaining ring and the lower end abutting against the bottom of the accommodating cavity. When the guide rod 422 moves downward, the first spring 421 can be continuously compressed, so that the first spring 421 continuously stores energy, providing a rebound force for the subsequent automatic unlocking.

[0048] In some embodiments, see Figure 3 A barrel base 510 is installed at the bottom of the barrel body 500, and a fixing plate 520 is installed at the bottom of the barrel base 510. A through hole is coaxially opened in the middle of the barrel base 510 and the middle of the fixing plate 520 to form an avoidance hole. A plurality of mounting holes are circumferentially opened on the inner side wall of the barrel base 510, and a plurality of elastic clips 600 are arranged in the mounting holes one by one.

[0049] Optionally, the barrel base 510 and the fixing plate 520 are sequentially installed below the barrel body 500 and connected to the bottom of the barrel body 500 by connecting screws penetrating from bottom to top.

[0050] Among them, the mounting holes are evenly opened along the circumference of the inner wall of the barrel base 510, the length direction of the mounting holes is consistent with the radial direction of the barrel body 500, and the elastic clip 600 is correspondingly installed in the mounting hole. When the elastic clip 600 is not subjected to force, the end with the guide slope 621 is located in the avoidance hole. After being subjected to external force, the end of the elastic clip 600 can shrink in the mounting hole.

[0051] In some embodiments, see Figure 3 The elastic clamp 600 includes a second spring 610 and a claw 620. The outer wall of the barrel base 510 is provided with a plurality of baffles 630. The plurality of baffles 630 are blocked one by one on the outer side of the mounting hole. The second spring 610 is passed through the mounting hole. One end of the second spring 610 is connected to the corresponding baffle 630, and the other end is connected to the claw 620. The guide slope 621 is located at the end of the claw 620 away from the second spring 610.

[0052] Specifically, the mounting hole is a through hole, and the outer side is blocked by a blocking piece 630, and the blocking piece 630 is installed on the outer wall of the barrel base 510 by screws. One end of the second spring 610 is connected to the corresponding blocking piece 630, and the other end is connected to the claw 620. The second spring 610 compresses or releases the elastic force to make the claw 620 move along the length direction of the mounting hole, thereby realizing the locking and unlocking of the barrel body 500 by the elastic clamp 600.

[0053] In some embodiments, see Figure 3 The barrel body 500 and the barrel base 510 are coaxially arranged, the diameter of the barrel body 500 is larger than the diameter of the barrel base 510 , and the difference between the two is larger than twice the thickness of the baffle 630 .

[0054] The baffles 630 are evenly distributed on the outer periphery of the barrel base 510, corresponding to the mounting holes one by one. The difference between the diameter of the barrel body 500 and the diameter of the barrel base 510 is greater than twice the thickness of the baffles 630. Even if there are baffles 630 on the opposite side of the outer wall of the barrel base 510, the baffles 630 will not protrude from the outer wall of the barrel body 500, so as to prevent the baffles 630 from affecting the installation of the barrel body 500 in the fixed base 100.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
