[0012] The beneficial effects of this utility model are:

[0013] This utility model relates to a locking device for a segmented cylindrical photosynthesis detection box. In use, the first pull seat and the second pull seat are fixedly located on the edges of two adjacent arc-shaped plates of the box. By rotating the locking disc with a wrench, the locking disc drives the pull rod to move laterally, and the pull rod then drives the locking block to move laterally. The lateral movement of the locking block can push the first pull seat closer to the second pull seat, thereby achieving a tight connection between the two adjacent arc-shaped plates of the box. The locking reliability is good, the sealing of the connection part is guaranteed, and the operation is simple. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] The locking device for the segmented cylindrical photosynthesis detection box in this embodiment includes a first pull seat 1, a second pull seat 2, a locking block 3, a pull rod 4, and a driver for driving the pull rod. The first pull seat and the second pull seat are arranged side by side.

[0020] In this embodiment, a concave notch is provided on the left side of the first pull seat, and the locking block 3 is disposed in the concave notch.

[0021] In this embodiment, the driver includes a ring sleeve 5 and a locking disc 6 that rotates with the ring sleeve. A connecting hole for fixing the ring sleeve is provided in the middle of the second pull base. A wrench connecting part 7 is provided in the middle of the top surface of the locking disc. The wrench connecting part 7 is a countersunk hexagonal socket that is compatible with an internal hexagonal wrench. Of course, in different embodiments, the structure of the wrench connecting part 7 can also be determined according to the type of wrench used. An end face thread tooth 8 is provided on the bottom surface of the locking disc 6. The end face thread tooth 8 extends in the shape of an Archimedean spiral.

[0022] The pull rod 4 is inserted into the second pull seat 2, the ring sleeve 5, the first pull seat 1 and the locking block 3. The pull rod is provided with a thread 9 for locking block connection, and the pull rod is also provided with an annular groove 10 that mates with the end face thread teeth 8 on the bottom surface of the lock plate. The pull rod slides in conjunction with the second pull seat, the ring sleeve and the first pull seat.

[0023] In this embodiment, the first pull base 1 and the second pull base 2 are provided with countersunk screw connection holes 11, such as... Figure 4 As shown, the first pull base 1 and the second pull base 2 are fixed to the edges of two adjacent arc plates 17 of the cylindrical photosynthesis detection box by countersunk screws. During assembly, first connect the locking block 3 to the pull rod 4, then insert the pull rod 4 sequentially through the first pull base 1, the second pull base 2, and the ring sleeve 5. Finally, rotate the locking disc 6 with an Allen wrench so that the end face threaded teeth 8 on the rotating locking disc 6 are screwed into the annular groove 10. Continuously rotating the locking disc 6 drives the pull rod 4 to move, which can close and lock the two adjacent arc plates together. The operation is simple and convenient. During disassembly, rotate the locking disc 6 in the opposite direction so that the end face threaded teeth 8 gradually exit from the annular groove 10. Then the locking block 3 and the pull rod 4 can be removed, thereby separating the arc plates of the cylindrical photosynthesis detection box.

[0024] As an improvement to the above embodiment, the locking disc 6 is provided with an annular flange 61; the ring sleeve 5 is composed of a left half sleeve 51 and a right half sleeve 52, and the ring sleeve 5 is provided with an annular groove that rotatably engages with the annular flange. In this improvement, the engagement of the annular flange 61 and the annular groove reliably limits the axial position of the locking disc 6, preventing it from dislodging from the ring sleeve. The ring sleeve is composed of a left half sleeve and a right half sleeve, allowing the locking disc 6 with the annular flange 61 to be easily inserted into the ring sleeve 5.

[0025] As an improvement to the above embodiment, a flat surface 53 is provided on the outer side of the sleeve 5 to prevent it from rotating.

[0026] As an improvement to the above embodiment, a first pull rope connector 12 and a second pull rope connector 13 are respectively provided on the sides of the first pull base 1 and the locking block 3, and the first pull rope connector and the second pull rope connector are connected by a pull rope 14. After the locking block 3 and the pull rod 4 are removed, they can be connected to the first pull base 1 through the first pull rope connector 12, the second pull rope connector 13 and the pull rope 14, which can avoid the problem of the locking block 3 and the pull rod 4 falling off and being lost.

[0027] As an improvement to the above embodiment, the first pull base and the second pull base are also provided with screw connection holes 16 for connecting the quick-connect socket 15, which allows the locking device to be connected to a photosynthesis detection instrument through the quick-connect socket 15, further expanding the function of the locking device.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and such modifications or substitutions should all be covered within the scope of the claims of this utility model.
