Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The features and properties of the present invention are described in further detail below with reference to examples.
Specific example 1 of a quick detachable connection structure of the present invention:
as shown in fig. 1 to 9, the connection structure capable of being quickly assembled and disassembled is simply referred to as a connection structure, the connection structure comprises an upper connection piece 1 and a lower connection piece 2, the upper connection piece 1 and the lower connection piece 2 are detachably connected, and fasteners such as screws and the like are not arranged on the whole, so that the assembly and disassembly are convenient.
As shown in fig. 1, a mounting tube 3 is fixedly mounted on the lower connector 2, and the upper end of the mounting tube 3 may or may not be closed. In this embodiment, the structure of the mounting cylinder 3 is as shown in fig. 7, a disc 19 is arranged at the lower end of the mounting cylinder 3, and a ring of engaging teeth 20 is fixed on the disc 19. The mounting tube 3 is vertically through, and guide planes 16 are arranged on two sides of the upper part.

A guide groove 15 is arranged below the guide plane 16, and the guide groove 15 is used for matching with a slide rail 23 on the ejector plate 10 to guide the movement of the ejector plate 10. Each guide plane 16 is provided with a second through hole 17 and a first through hole 18 which penetrate through the mounting cylinder 3, and the first through holes are long holes. The mounting cylinder 3 is further provided with a hinge shaft mounting hole 22 which radially penetrates through the mounting cylinder 3, the hinge shaft mounting hole 22 extends along the radial direction of the mounting cylinder 3, and the extending direction of the hinge shaft mounting hole 22 is parallel to the two guide planes 16. As shown in fig. 7, a push rod through hole 21 is formed in the disk at a position corresponding to the guide groove 15, the push rod through hole 21 vertically penetrates the disk, and the push rod 25 passes through the push rod through hole 21 to guide the push rod 25.
In this embodiment, an installation section of thick bamboo 3 is fixed on lower connecting piece 2 through the riveted mode, specifically, has seted up the through-hole on lower connecting piece 2, and installation section of thick bamboo 3 passes the through-hole from bottom to top and rivets afterwards, realizes fixedly through the cooperation of interlock tooth 20 with lower connecting piece 2.
As shown in fig. 4 to 6, a hinge shaft 4 is mounted on a hinge shaft mounting hole 22 of the mounting tube 3, and as shown in fig. 1 to 3, two swing links 5 are mounted on the hinge shaft 4, and the two swing links 5 are arranged to cross each other to form a scissor arm. The upper end of the swing rod 5 is hinged with a lock rod 6 through a pin shaft 13, the two lock rods 6 are also arranged in a cross way, and the lower end of the swing rod 5 is hinged with a connecting rod 8. A pulling plate 9 is arranged below the mounting cylinder 3, the lower ends of the two connecting rods 8 are hinged on the pulling plate 9, and meanwhile, a tension spring 12 is arranged between the pulling plate 9 and the hinge shaft 4. When the device is used, when the pulling plate 9 is pushed or pulled downwards, the pulling plate 9 overcomes the elastic force of the tension spring 12, so that the upper ends of the two connecting rods 8 are closed in opposite directions, the upper ends of the two swing rods 5 are closed in opposite directions, and meanwhile, the upper ends of the two lock rods 6 are moved upwards along the wall of the installation barrel 3. After the driving force to the pulling plate 9 is removed, the pulling plate 9 moves upwards under the elastic restoring action of the tension spring 12 due to the fixed arrangement of the hinge shaft 4, and all the connecting rods move or swing reversely. As shown in fig. 1, a lock rod spring 7 is further installed between the upper end of the lock rod 6 and the cylinder wall of the installation cylinder 3, and the lock rod spring 7 is a tension spring.
As shown in fig. 2 and 3, two bearing rods 14 are fixed on the pulling plate 9, the positions of the bearing rods 14 correspond to the ejector rod through holes 21, and the upper ends of the bearing rods 14 penetrate into the ejector rod through holes 21 when in use.
As shown in fig. 2 and 3, the upper end of the swing rod 5 is provided with a swing rod hook 51, the swing rod hook 51 corresponds to the first through hole 18, the swing rod hook 51 can swing into and penetrate through the first through hole 18, the upper side surface of the swing rod hook 51 is an inclined surface and is a swing rod direction-changing slope surface 52, and the lower side surface is a limit stop surface 53. The upper end of the lock rod 6 is provided with a lock rod hook 61, and the lock rod hook 61 corresponds to the second perforation 17 and can be hooked in the second perforation 17. The lower side surface of the locking bar hook 61 is an inclined surface and changes direction to a slope for the locking bar.
As shown in fig. 1 and 4, a push plate 10 is sleeved outside the mounting tube 3, the structure of the push plate 10 is shown in fig. 8, two ejector rods 25 are fixed at the lower end of the push plate 10, the ejector rods 25 can penetrate through the ejector rod through holes 21 and push the bearing rod 14 when in use, two slide rails 23 are further integrally formed on the inner wall of the push plate 10, and the slide rails 23 can be matched with the guide grooves 15 to guide the movement of the push plate 10.
As shown in fig. 1, a push plate spring 11 is pressed between the lower connecting member 2 and the push plate 10, and the push plate spring 11 is a compression spring and applies an upward acting force to the push plate 10.
In order to match the installation of the installation barrel 3, an installation hole is arranged on the upper connecting piece 1, the shape of the installation hole is consistent with that of the upper end of the installation barrel 3, and two planar guide inner wall surfaces are arranged.
As shown in fig. 1 and 9, the connection structure further includes a fixing strip 24, the fixing strip 24 is installed between the upper connection member 1 and the lower connection member 2 when in use, a through groove 241 is opened on an upper end surface of the fixing strip 24, and the through groove 241 is a through groove.
The using process of the invention is as follows: before the upper connecting piece 1 and the lower connecting piece 2 are not connected, the lock rod hook 61 is positioned inside the mounting cylinder 3 and below the second through hole 17, the swing rod hook 51 penetrates through the first through hole 18 and extends to the outside of the mounting cylinder 3, and the bearing rod 14 penetrates into the ejector rod through hole 21. When the upper connecting piece 1 is sleeved outside the installation cylinder 3 from top to bottom, when the upper connecting piece 1 passes through the swing rod hook 51, the upper end of the swing rod 5 is pushed to retract inwards by matching with the swing rod redirection slope 52, and the upper connecting piece 1 can cross the swing rod 5. Although the upper end of the swing rod 5 retracts inwards, the swing angle is small, and the locking rod hook 61 is not moved to the second through hole 17 and still remains in the installation cylinder 3.
