[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the following embodiments are combined with the accompanying drawings to specifically illustrate the technical solutions of the present invention.

[0023] It should be noted that the accompanying drawings are schematic diagrams only and do not represent actual dimensions. In the present invention, the terms "first", "second", etc. are used to distinguish objects and are not necessarily used to describe a specific order or sequence. The directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "vertical", "horizontal", "transverse", "longitudinal", etc. are based on the directions or positional relationships shown in the accompanying drawings. These terms are mainly for better describing the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0024] See Figure 2 In one embodiment of the present invention, a connecting lock for easy splicing is provided, which includes: a first module 1 fixed to a first splicing object 100 and a second module 2 fixed to a second splicing object 200. In this embodiment, the first splicing object 100 and the second splicing object 200 are two parts of a prop to be spliced.

[0025] See Figures 1 to 5 The first module 1 includes a first housing 11 and a locking shaft 12. The first housing 11 is provided with a locking shaft hole, and the locking shaft 12 is located in the first housing 11 and fixed in the locking shaft hole. The first housing 11 is also provided with a fixing hole for installing screws to fix it to the first splicing object.

[0026] The first trough shell 11 includes a U-shaped trough shell body 111 and a fixed edge 112 set at the edge of the U-shaped trough shell body. The top angle of the fixed edge 112 is set as an arc chamfer. The width dimension of the fixed edge 112 (such as Figure 5 The overall height of the U-shaped trough shell body 111 (as shown in FIG. Figure 4 As shown in a) is 35mm to 40mm. The overall length of the U-shaped trough shell body 111 (as shown in Figure 4 b) is 80mm to 100mm. The width of the U-shaped trough shell body 111 (as shown in FIG. Figure 4 c) shown is 10mm to 12mm.

[0027] The fixing hole 113 is provided on the fixing edge 112 of the first pot shell 11. In this embodiment, Figure 4As shown, there are four groups of fixing holes 113, each group having two fixing holes. The two fixing holes 113 in each group can be the same or different. When the two fixing holes 113 in each group are set as holes of the same type, a hole in one position can be selected according to actual needs to install a screw. In this case, the two holes in each group play the role of selecting a position. When the two fixing holes 113 in each group are set as holes of different types, for example, one hole is a hole opened on a plane and the other hole is an inwardly concave hole, different types of holes can match different screws, so one of the holes can be selected according to actual needs to install a corresponding type of screw.

[0028] like Figure 3 As shown, three through holes 114 are provided on the U-shaped trough shell body 111. In actual situations, screws can be installed in the fixing holes 113 and / or part of the through holes 114 according to the structural characteristics of the props to be spliced, so as to achieve fixation with the props. Figure 2 , the figure shows a screw 26, the first module 1 is fixed to the first splicing object 100 by installing the screw through the first main fixing hole, and the second module 2 is fixed to the second splicing object 200 by installing the screw through the second main fixing hole.

[0029] See Figure 1 、 Figure 2 、 Figures 6 to 9 The second module 2 includes a second slot shell 21, a countersunk threaded column 22, a locking hook 23, a limiting pin 24, and a limiting cover 25.

[0030] The second trough shell 21 has the same structure as the first trough shell 11. The second trough shell 21 includes a U-shaped trough shell body 211 and a fixed edge 212 disposed at the edge of the U-shaped trough shell body. Fixing holes 213 are provided in the fixed edge 212 of the second trough shell 21. Three through holes 214 are provided in the U-shaped trough shell body 211.

[0031] The second housing 21 has a threaded hole into which a countersunk threaded post 22 is threadedly mounted. The countersunk threaded post 22 has a countersunk groove that can be any of an internal triangle, internal hexagon, or plum blossom shape. In this embodiment, a hexagonal countersunk threaded post 22 is used in conjunction with an internal hexagonal wrench. Inserting the hexagonal wrench into the internal hexagonal groove and turning the hexagonal wrench rotates the countersunk threaded post 22.

[0032] The lock hook 23 is located within the second housing 21 and has an overall delta-shaped structure. A first end 231 of the lock hook 23 is secured to the countersunk threaded post 22, which can be welded. A second end 232 of the lock hook 23 is a curved hook that engages the lock shaft 12.

[0033] A limiting pin 24 is fixedly installed in the second trough shell 21 . The limiting pin 24 is located on one side of the hook-shaped end of the locking hook 23 and is fixed in one of the through holes 214 on the U-shaped trough shell body 211 .

[0034] The retaining cover 25 is welded and fixed to the first trough shell 11. It has an arched structure, consisting of a connected arched portion and two side panels. The first end 231 of the locking hook 23 is located in the space between the two side panels. The arched portion is located outside the second end 232 of the locking hook 23. The distance between the two side panels matches the thickness of the locking hook 23, so that the locking hook 23 is retained between the two side panels, ensuring that it does not deviate or wobble during rotation, maintaining stability. Preferably, the distance between the two side panels is set to be 0.5 mm to 1 mm greater than the thickness of the locking hook 23.

[0035] See Figure 2 The usage of the convenient splicing connecting lock of the embodiment of the utility model is as follows:

[0036] The first module 1 is pre-fixed to the first splicing object 100 (part of the prop), and the second module 2 is pre-fixed to the second splicing object 200 (another part of the prop). At the exhibition site, the two parts of the prop are spliced ​​and contacted so that the positions of the first module 1 and the second module 2 correspond. Then, a hexagonal wrench is inserted into the hexagonal countersunk groove of the countersunk threaded column 22. Turning the hexagonal wrench can drive the countersunk threaded column 22 to rotate, thereby driving the locking hook 23 to rotate until the curved hook-shaped second end 232 is matched with the locking shaft 12 to hook and connect the two parts of the prop. When disassembly is required, the hexagonal wrench is used again to rotate the countersunk threaded column 22 in the opposite direction, driving the second end 232 of the locking hook 23 to disengage the locking shaft 12, thus separating the two parts of the prop. After disassembly, it does not affect the reuse of the prop.

[0037] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to fall within the scope of protection of the present invention.
