The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0041] The following is attached to the instruction manual Figures 4 to 11 , the base of the utility model is introduced.

[0042] In one embodiment, if Figure 4 and Figure 5 As shown, the base includes a supporting base 200 and a top pressing assembly.

[0043] The supporting base 200 is provided with a receiving cavity 210 adapted to the special-shaped tube 101 to receive the special-shaped tube 101 .

[0044] The pushing assembly includes a pushing frame 300 and a pressing rod 400. The pushing frame 300 is slidably arranged on the supporting base 200 to push the pressing rod 400 so that the pressing rod 400 presses the special-shaped tube 101 into the accommodating cavity 210 to eliminate the deformation of the special-shaped tube 101.

[0045] The supporting base 200 is also provided with a coupling shaft 220 , and the pushing frame 300 is provided with a locking track. The coupling shaft 220 can slide in the locking track and lock the pushing frame 300 at a set position.

[0046] When in use, each small tube of the special-shaped tube 101 is placed in the accommodating cavity 210, and the push frame 300 is pressed to move downward. During the downward movement, the push frame 300 pushes the pressure rod 400 so that the pressure rod 400 presses the special-shaped tube 101 into the accommodating cavity 210 to eliminate the deformation of the special-shaped tube 101. At the same time, the coupling 220 can guide and slide in the locking track and lock the push frame 300 in a set position, so that the special-shaped tube 101 is kept in a pressed state, which is convenient for subsequent operations and is not prone to filling errors, thereby greatly improving production efficiency and product quality, and also helping to reduce labor costs and improve the level of automation.

[0047] In one embodiment, if Figure 4 , Figure 5 and Figure 6 As shown, an arc-shaped guide groove 301 is provided on the pushing frame 300, one end of the pressure rod 400 is fixed on the supporting base 200, and the other end is located in the arc-shaped guide groove 301. When the pushing frame 300 slides down, the arc-shaped guide groove 301 can push the pressure rod 400 to cause the pressure rod 400 to undergo elastic deformation.

[0048] Specifically, Figure 4 and Figure 7 As shown, the push frame 300 is in an inverted U shape, including two cantilever arms and a horizontal section. The support base 200 is provided with slots for the two cantilever arms of the push frame 300 to be inserted, and the push frame 300 can be guided and slid up and down in the fork groove. The horizontal section of the push frame 300 is provided with arc-shaped guide grooves 301, and there are three arc-shaped guide grooves 301. Correspondingly, there are also three pressure rods 400 on the support base 200. In other embodiments, other numbers of pressure rods 400 and corresponding arc-shaped guide grooves 301 can also be provided.

[0049] like Figure 6 As shown, the bottom of the arc-shaped guide groove 301 is an arc-shaped guide surface, so as to facilitate elastic deformation of the pressure rod 400.

[0050] The pressure rod 400 is a strip-shaped structure or a stick-shaped structure, and can undergo elastic deformation. For example, the pressure rod 400 can be made of nickel-titanium alloy, hard plastic or spring steel.

[0051] In one embodiment, if Fig. 9 As shown, the coupling 220 includes a rotating handle 222 and a central axis 221 and a sliding axis 223 located at both ends of the rotating handle 222. The central axis 221 is rotatably set on the supporting base 200, and the sliding axis 223 is guided and slidably set in the locking track and can rotate around the central axis 221.

[0052] Specifically, the sliding shaft 223 can be guided to slide in the locking track and rotate around the central axis 221 through the rotating handle 222, so that the push frame 300 can always be guided to slide up and down.

[0053] In one embodiment, if Figure 6 and Figure 8 As shown, the locking track includes an upward segment 310, a locking segment 320 and a downward segment 330. The upward segment 310 and the downward segment 330 are located below the locking segment 320. Both ends of the locking segment 320 are respectively connected to the upward segment 310 and the downward segment 330, and the end of the downward segment 330 merges into the upward segment 310.

[0054] During the downward movement of the push frame 300, the sliding shaft 223 first enters the upward section 310, and then enters the locking section 320, and is locked in the set position. At this time, the pressing rod 400 has pressed the special-shaped tube 101 into the accommodating cavity 210 and maintained at the current position to eliminate the deformation of the special-shaped tube 101. When the special-shaped tube 101 needs to be taken out after the subsequent filling is completed, the sliding shaft 223 enters the downward section 330, thereby releasing the restriction on the pressing rod 400, and the pressing rod 400 is reset, and the special-shaped tube 101 can be taken out.

[0055] In one embodiment, if Figure 6 , Figure 8 and Fig.10 As shown, an elastic reset member for resetting the pushing frame 300 is provided between the pushing frame 300 and the supporting base 200 , one end of the elastic reset member is fixedly connected to the pushing frame 300 , and the other end is fixedly connected to the supporting base 200 .

[0056] In order to make it easier for the sliding shaft 223 to enter the locking section 320 and the downward section 330, the locking section 320 has a first guide section 321 for guiding the sliding shaft 223 into the locking section 320, a recess 322 for accommodating the sliding shaft 223, and a second guide section 323 for guiding the sliding shaft 223 into the downward section 330, wherein the starting point of the second guide section 323 is located on the side of the recess 322 close to the upward section 310.

[0057] When locking, the push frame 300 is pressed, and the sliding shaft 223 enters the first guide section 321 from the upward section 310. The first guide section 321 guides the coupling shaft 220 to a position close to the concave point 322. At this time, the push frame 300 is no longer pressed, and the sliding shaft 223 is constrained in the concave point 322 under the action of the elastic reset member, thereby being locked. When unlocking, the push frame 300 is pressed to overcome the resistance of the elastic reset member. Since the starting point of the inclined guide section is located on the side of the concave point 322 close to the upward section 310, when pressed, the sliding shaft 223 will enter the downward section 330 along with the second guide section 323, thereby being unlocked smoothly. At this time, the push frame 300 is no longer pressed, and the push frame 300 is reset under the action of the elastic reset member.

[0058] In one of the embodiments, in order to prevent the sliding shaft 223 from directly entering the downward section 330 during the downward pressing process, the upward section 310 includes a third guide section 311 and a fourth guide section 312, wherein the end of the third guide section 311 is located above the end of the downward section 330, and the depth of the third guide section 311 is greater than the depth of the downward section 330, wherein a portion of the third guide section 311 is a vertical section extending in the vertical direction, and the sliding shaft 223 will enter the vertical section after detaching from the downward section 330, and the sliding shaft 223 is elastically floatingly arranged on the rotating handle 222, and the sliding shaft 223 can adapt to the depth of the locking track.

[0059] Specifically, the third guide section 311 passes through the push frame 300 , while the sink forming the descending section 330 does not pass through the push frame 300 , so that the depth of the third guide section 311 is greater than the depth of the descending section 330 .

[0060] The rotating handle 222 is provided with a mounting hole, in which a spring is provided. One end of the spring is located in the mounting hole, and the other end is fixedly connected to the sliding shaft 223 , so that the sliding shaft 223 can adapt to the depth of the locking track.

[0061] When in use, the sliding shaft 223 first enters the third guide section 311 . Since the depth of the third guide section 311 is greater than the depth of the descending section 330 , the sliding shaft 223 will only slide in the third guide section 311 during the downward pressing process and will not enter the descending section 330 by mistake.

[0062] Preferably, in order to allow the sliding shaft 223 to smoothly enter the locking section 320, the depth of the fourth guide section 312, the depth of the locking section 320 and the depth of the descending section 330 are the same, and the third guide section 311 and the fourth guide section 312 are transitioned through an inclined surface. In other embodiments, the first guide section 321 and the second guide section 323 can also be transitioned through an arc surface.

[0063] Specifically, the push frame 300 has a mounting boss 302 , and an accommodating groove for the mounting boss 302 to move up and down is provided on the outer side wall of the supporting base 200 .

[0064] In one embodiment, if Fig.10 As shown, the elastic return member is a compression spring 510. Specifically, the upper end of the compression spring 510 is fixedly connected to the lower surface of the mounting boss 302, and the lower end of the compression spring 510 is fixedly connected to the lower surface of the accommodating groove.

[0065] In another embodiment, if Fig.11As shown, the elastic return member is a tension spring 520 . Specifically, the upper end of the tension spring 520 is fixedly connected to the upper surface of the accommodating groove, and the lower surface of the tension spring 520 is fixedly connected to the upper surface of the mounting boss 302 .

[0066] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
