Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, the present invention is a schematic diagram of a fast-assembling and fast-fetching mechanism. The utility model provides a fast-assembling quick access mechanism 2, it includes: a fixed seat 21, a movable fastener 22, a first elastic element 23, a pivot shaft 24, a slide block 25, a second elastic element 26, a push rod 27, a key 28 and a shell 29.
The fixed base 21 is fixedly mounted on the housing 29 by a fastener such as a screw. The fixing seat 21 is provided with a butt joint cavity 219 which is through from front to back. The side wall of the fixing base 21 is provided with a sliding groove 212 at a position close to the rear end 216. The pushing portion 251 of the slider 25 is correspondingly disposed in the sliding groove 212 and extends into the docking cavity 219. The pivot shaft 24 is disposed in the positioning hole 211 of the fixing base 21 and the positioning hole 221 of the movable fastener 22 for pivotally connecting the movable fastener 22 to the fixing base 21. The movable fastener 22 is fastened to the front end of the fixed seat 21 and connected to the fixed seat 21 through a first elastic element 23.
Referring to fig. 2 and 3, fig. 2 is a schematic view of the quick-mount quick-access mechanism of the present invention, wherein the movable fastener is in a closed position. Fig. 3 is a schematic view of the quick-mounting and quick-fetching mechanism of the present invention, wherein the movable fastener is in an open position. The front end 215 of the fixed seat 21 is provided with a first semicircular ring 214. The inner edge of the front end 215 is polygonal (e.g., octagonal) in contour; referring back to fig. 1, the inner edge of the rear end 216 is rounded in profile. The movable fastener 22 is provided with a second semicircular ring 222.
Referring to fig. 2, when the movable fastener 22 is in the closed position, the first elastic member 23 is in a free state or a slightly stretched state, and the second semicircular ring 222 is closed with the first semicircular ring 214, that is, the upper end of the second semicircular ring 222 is in a fitted state or a state with a small gap with the upper end of the first semicircular ring 214. Second semi-circular ring 222 closes into a circle with first semi-circular ring 214.
Referring to fig. 3, when the movable fastener 22 is in the open position, the first elastic member 23 is in a large stretching state, and the second semi-circular ring 222 is open relative to the first semi-circular ring 214, that is, the upper end of the second semi-circular ring 222 is open to a set degree relative to the upper end of the first semi-circular ring 214. The force for overcoming the first elastic element 23 can be derived from an external force to press the button 28, so that the push rod 27 cooperating with the button 28 is actuated, and then the push rod 27 can apply a force to the movable fastener 22, so that the second semicircular ring 222 is expanded to a set degree relative to the first semicircular ring 214.
It is worth mentioning that the front end 215 and the rear end 216 of the holder 21 are different and can be well adapted to a docking member inserted into the docking cavity 219 from the front end 215, for example, a stirring head, which will be described in detail later; and another docking member inserted into the docking cavity 219 from the rear end 216, for example, this docking member is a drive mechanism, i.e., the drive mechanism and the agitator head dock within the docking cavity 219.
Referring to fig. 4, fig. 4 is an exploded view of the fast-assembling and fast-fetching mechanism of the present invention, omitting the housing. As can be seen, in the fixed seat 2, a positioning hook 217 is provided; in the movable fastener 22, a positioning hole 223 is provided. The two ends of the first elastic element 23 can connect the upper end of the movable fastener 22 with the upper end of the fixed seat 2 by respectively connecting the positioning hook 217 and the positioning hole 223. The movable buckle 22 is provided with a tongue portion 224 protruding toward the side where the first elastic member 23 is located.
The pivot shaft 24 is provided with a pivot portion 241 and a fixing portion 242. The pivot portion 241 is correspondingly received in the positioning hole 221 of the movable fastener 22. The fixing portion 242 is correspondingly disposed in the positioning hole 211 of the fixing base 21. Patterns or other structures are arranged on the outer surface of the fixing part 242, so that the fixing part 242 is difficult to rotate in the positioning hole 211; the appearance of the pivot portion 241 is smooth, so that the lower end of the movable buckle 22 can rotate relatively easily with respect to the lower end of the fixed seat 21.
The slider 25 includes, in addition to the pushing portion 251, a positioning post 252 for matching with the second elastic element 26 to position the second elastic element 26; and a base 253 for engaging with the housing 29 (for example, the housing 29 is provided with a sliding slot corresponding to the base 253), so as to be capable of moving forward and backward relative to the fixing base 21, wherein the maximum value of the set distance of the forward and backward movement is limited by the forward and backward dimension of the sliding slot 212.
It is worth mentioning that the portion of the pushing portion 251 that extends into the docking cavity 219 is limited to be able to be pushed by the structural portion of the mixing head inserted into the docking cavity 219 from the front end 215, and to not hinder the normal operation of the structural portion of the driving mechanism inserted into the docking cavity 219 from the rear end 216.
One end of the second elastic element 26 is sleeved on the positioning column 252 and abuts against the sliding block 25. Referring back to fig. 1, the other end of the second resilient element 26 abuts against a mating structure on the housing 29. That is, when the slider 25 slides backward by an external force, the second elastic member 26 can be compressed. Once the external force is released, the second elastic element 26 returns to the original position, and the slider 25 can be driven to slide forwards.
The push rod 27 comprises a positioning hole 271 for matching with the positioning post 213 on the fixing base 21; a finger portion 272 for applying a force to an upper end of the movable catch 22; and a base 273 for mating with the key 28.
The finger portion 272 has an arc shape and matches with the outer peripheral contour of the holder 21. The finger tip of the finger portion 272 faces the upper end of the movable catch 22 and is located below the tongue plate 224 at the upper end of the movable catch 22. It can be understood that the tongue plate 224 is located above the fingertips of the fingers 272, and can serve as a limiting function, which is beneficial to limit the fingers 272 from above to be attached to the periphery of the fixing base 21 as much as possible.
In the present embodiment, the first elastic element 23 is a tension spring, and the second elastic element 26 is a compression spring. In other embodiments, the first elastic element 23 may be a compression spring and the second elastic element 26 may be a tension spring.
