[0052] The locking rod 4 is installed in the vertical base plate 3 and passes through the connecting sleeve 6. At the same time, it can move axially. The connecting sleeve 6 is locked to the fixed installation block 5 through the axial movement of the locking rod 4, and the vertical base plate 3 is fixedly installed on the upper end of the bottom plate 1.

[0053] In this embodiment, a buckle assembly for fixing the side panel 2 to the vertical base plate is installed at the end of the locking rod 4 through a hinge connection.

[0054] In this embodiment, the buckle assembly includes a connecting plate 7, a buckle plate 8 having a buckle groove, and a buckle pin 9 fixedly mounted on the side plate;

[0055] The two ends of the connecting plate are rotatably connected to the buckle plate 8 and the locking rod 4 through pins respectively;

[0056] The upper portion of the buckle plate 8 is rotatably mounted on the vertical base plate 3 via a pin shaft, and the buckle plate 8 is driven to rotate by the axial movement of the locking rod 4, and the engagement state of the buckle groove and the buckle plate 8 is controlled.

[0057] In this embodiment, the fixed connection block 5 is provided with a movable groove 5.1 matching with the locking rod 4. The movable groove has a tapered circular hole. An opening groove 5.2 is provided at the upper end of the movable groove 5.1 and the opening distance is smaller than the inner diameter of the movable groove.

[0058] In this embodiment, the locking rod 4 is provided with a flat portion 4.1 which matches the opening slot 5.2 and can be separated from the opening slot.

[0059] In this embodiment, the buckle plate 8 is provided with an elastic compression buffer groove 8.1.

[0060] In this embodiment, the locking rod and the movable groove are locked by a taper, and the connecting sleeve and the fixed connecting block are locked by a taper; the hole and the shaft are matched by a taper, which ensures the stability of the locking and reduces the risk of loose fit between the shaft and the hole.

[0061] In this embodiment, the upper end of the fixed connection block is provided with a rounded corner for facilitating assembly and guidance, and the upper end of the open groove is provided with an oblique angle for facilitating assembly and guidance.

In the process of installing the connecting sleeve 6 and the fixed connecting block 5, the flat portion 4.1 of the locking rod 4 is aligned with the open groove 5.2 of the connecting block 5, so that the locking rod 4 can smoothly enter the movable groove 5.1; at the same time, when the side plate 2 moves, the buckling pin 9 drives the buckle plate to rotate, so that the buckling groove is buckled on the buckling pin 9. In the process of the buckle plate rotating, it drives the axis of the locking rod to move, and makes the flat portion and the open groove of the connecting block misaligned, so that the connecting sleeve is locked to the connecting block, thereby realizing the fastening connection between the bottom plate 1, the side plate 2 and the vertical base plate 3.

[0064] Embodiment 2:

[0065] like Figure 11-Figure 12 As shown, a precise quick connection device comprises a fixed connection block 5, a connection sleeve 6 and a locking rod 4; the fixed connection block 5 is fixedly mounted on the upper end of the base plate 1;

[0066] The connecting sleeve 6 is fixedly installed in the vertical base plate 3 and is movably sleeved on the fixed connecting block 5;

[0067] The locking rod 4 is installed in the vertical base plate 3 and passes through the connecting sleeve 6. At the same time, it can move axially. The connecting sleeve 6 is locked to the fixed installation block 5 through the axial movement of the locking rod 4, and the vertical base plate 3 is fixedly installed on the upper end of the bottom plate 1.

[0068] In this embodiment, the fixed connection block 5 is provided with a movable groove 5.1 matching with the locking rod 4, and an opening groove 5.2 with an upper opening and an opening distance smaller than the inner diameter of the movable groove is provided at the upper end of the movable groove 5.1.

[0069] In this embodiment, the locking rod 4 is provided with a flat portion 4.1 which matches the opening slot 5.2 and can be separated from the opening slot.

[0070] In this embodiment, a buckle assembly for fixing the side panel 2 to the vertical base plate is installed at the end of the locking rod 4 through a hinge connection.

[0071] In this embodiment, the buckle assembly includes a front connecting member 10, an intermediate rotating member 8 and a rear connecting member 7;

[0072] The middle and upper part of the intermediate rotating member 8 is rotatably mounted on the vertical base plate 3 through a pin shaft, and the two ends of the intermediate rotating member 8 are rotatably connected to the front connecting member 10 and the rear connecting member 7 through pin shafts, wherein the front connecting member 10 is rotatably mounted with a vertical transmission rod 11 through a pin shaft, and the rear connecting member 7 is rotatably connected to the locking rod 4 through a pin shaft;

[0073] The transmission rod 11 is movably mounted vertically on the side plate.

[0074] When the present embodiment is in use, the fixed connection block 5 is prefabricated on the upper end of the bottom plate, the connection sleeve and the locking rod are prefabricated and installed in the vertical base plate 3, and the buckle pin 9 is prefabricated and installed in the side plate 2. When in use, the vertical base plate is installed on the bottom plate and positioned by the fixed connection block, and the connection sleeve is sleeved on the fixed connection block 5 by its own gravity. In the process of installing the connection sleeve 6 and the fixed connection block 5, the flat portion 4.1 of the locking rod 4 is aligned with the open groove 5.2 of the connection block 5, so that the locking rod 4 can smoothly enter the movable groove 5.1; at the same time, when the side plate is installed, when the vertical transmission rod moves vertically, the vertical transmission rod drives the intermediate rotating member 8 to rotate, and when the intermediate rotating member 8 rotates, it drives the axis of the locking rod to move, and makes the flat portion and the open groove of the connection block misaligned, so that the connection sleeve is locked to the connection block, thereby realizing the tight connection between the bottom plate 1 and the vertical base plate 3; in this process, one force point realizes the transmission of multi-point linear array and circular array equal forces, thereby realizing linear and circumferential multi-point locking or unlocking.

[0075] In this embodiment, the locking rod and the movable groove are locked by a taper, and the connecting sleeve and the fixed connecting block are locked by a taper; the hole and the shaft are matched by a taper, which ensures the stability of the locking and reduces the risk of loose fit between the shaft and the hole.

[0076] In this embodiment, the upper end of the fixed connection block is provided with a rounded corner for facilitating assembly and guidance, and the upper end of the open groove is provided with an oblique angle for facilitating assembly and guidance.

[0077] In this embodiment, the axial through hole of the connecting sleeve (the through hole for installing the fixed mounting block) is provided with a taper, and the fixed mounting block matching the through hole is also provided with a taper matching therewith; at the same time, the transverse through hole of the connecting sleeve (the through hole for installing the locking rod) is also provided with a taper, and the locking rod matching the transverse through hole is also provided with a taper matching therewith. Through the taper matching, the installation is more convenient and stable.

[0078] Embodiment three:

[0079] like Figure 13-Figure 18As shown, compared with the first and second embodiments, this embodiment differs in the locking rod 4 and the connecting sleeve 6. In this embodiment, the connecting sleeve is provided with a transverse locking rod movable hole, and an internal thread 6.1 is provided at one end of the locking rod movable hole;

[0080] The locking rod is provided with a threaded portion 4.2 matching the nut, and the flat portion 4.1 is located at the threaded portion. Meanwhile, a hexagonal hole 4.3 is provided at one end of the locking rod.

[0081] In this embodiment, the locking rod can be driven by an Allen wrench. When in use, the Allen wrench is inserted into the hexagonal hole, and the locking rod is driven to rotate by rotating the Allen wrench. Since the threaded portion of the locking rod matches the internal thread, when the locking rod rotates, the locking rod will move axially, thereby achieving alignment or misalignment of the flat portion and the open groove, thereby achieving a locking connection between the connecting sleeve and the locking rod.

[0082] In this embodiment, the locking rod and the movable groove are locked by a taper, and the connecting sleeve and the fixed connecting block are locked by a taper; the hole and the shaft are matched by a taper, which ensures the stability of the locking and reduces the risk of loose fit between the shaft and the hole.

[0083] In this embodiment, the upper end of the fixed connection block is provided with a rounded corner for facilitating assembly and guidance, and the upper end of the open groove is provided with an oblique angle for facilitating assembly and guidance.

[0084] In this embodiment, the axial through hole of the connecting sleeve (the through hole for installing the fixed mounting block) is provided with a taper, and the fixed mounting block matching the through hole is also provided with a taper matching therewith; at the same time, the transverse through hole of the connecting sleeve (the through hole for installing the locking rod) is also provided with a taper, and the locking rod matching the transverse through hole is also provided with a taper matching therewith. Through the taper matching, the installation is more convenient and stable.

[0085] Embodiment 4:

[0086] like Figure 19-21 As shown, compared with the third embodiment, this embodiment has a different structure between the fixed mounting block 5 and the connecting sleeve 6. In this embodiment, the fixed connecting block sleeve is provided with a plurality of connecting rings 12 clamped between the connecting sleeve and the bottom plate, and the connecting rings are fixedly mounted on other vertical base plates outside the fixed connecting block.

[0087] In this embodiment, the locking rod and the movable groove are locked by a taper, and the connecting sleeve and the fixed connecting block are locked by a taper; the hole and the shaft are matched by a taper, which ensures the stability of the locking and reduces the risk of loose fit between the shaft and the hole.

[0088] In this embodiment, the upper end of the fixed connection block is provided with a rounded corner for facilitating assembly and guidance, and the upper end of the open groove is provided with an oblique angle for facilitating assembly and guidance.

[0089] In this embodiment, the locking rod can be driven by an inner hexagonal wrench. When in use, the inner hexagonal wrench is inserted into the inner hexagonal hole, and the locking rod is driven to rotate by rotating the inner hexagonal wrench. Since the threaded portion of the locking rod matches the internal thread, when the locking rod rotates, the locking rod will move axially, thereby achieving alignment or misalignment between the flat portion and the open groove, thereby achieving a locking connection between the connecting sleeve and the locking rod;

[0090] However, during use of this embodiment, an inner cone hole connecting ring can be installed, and the connecting ring can be fixedly connected to the surrounding vertical, horizontal and inclined substrates, so as to achieve positioning and fixing of multiple substrates through one connecting device.

[0091] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general scheme defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the scheme and novel features disclosed herein.
