Therefore, they should not be construed as limiting this invention.

[0016] Example 1: Please see Figure 1-5 As shown, this application provides a technical solution: an adjustable disc-lock scaffold, including uprights 12, a horizontal connecting rod 3 disposed between two uprights 12, a connecting plate 13 on the uprights 12, a detachable first connecting member 14 on the connecting plate 13, the horizontal connecting rod 3 including a first rod 31 with one end connected to the first connecting member 14, a second rod 32 with one end connected to the first connecting member 14 on the other side, and a first adjusting rod 33 disposed between the first rod 31 and the second rod 32 for adjusting the distance between the first rod 31 and the second rod 32. Both the first rod 31 and the second rod 32 are provided with internal threads on the side where they connect to the first adjusting rod 33, and the first adjusting rod 33 is provided with matching external threads; a first locking nut 34 is also provided on the first adjusting rod 33.

[0017] Using the above structure, the connection between the first connecting member 14 and the first rod 31 and the second rod 32 can be achieved by welding or threaded connection. The internal threads on the first rod 31 and the internal threads on the second rod 32 have opposite directions of rotation, or the threads at both ends of the first adjusting rod 33 have opposite directions of rotation. In this way, when it is necessary to adjust the distance between the two uprights 12, the first adjusting rod 33 can be rotated in one direction. Through the threaded engagement between the first adjusting rod 33 and the first rod 31 and the second rod 32, the first rod 31 and the second rod 32 move closer or further apart simultaneously under the action of the threads, thereby causing the two connected uprights 12 to move closer or further apart, thus achieving the purpose of adjusting the distance between the two uprights 12.

[0018] In a preferred embodiment, two parallel clamping surfaces 331 are provided in the middle of the first adjusting rod 33.

[0019] With the above structure, the upper and lower clamping surfaces 331 of the first adjusting rod 33 can be clamped with an adjustable wrench, and then the adjustable wrench can be rotated to rotate the first adjusting rod 33.

[0020] In a preferred embodiment, a first through hole 131 is provided on the connecting plate 13, and a matching second through hole 142 is provided on the first connector 14. A first pin 15 for fixing the connecting plate 13 and the first connector 14 is provided in the first through hole 131 and the second through hole 142.

[0021] With the above structure, when it is necessary to fix the first connector 14 to the connecting plate 13, the first through hole 131 and the second through hole 142 can be aligned, and then the detachable first pin 15 can be inserted. The first pin 15 has a tapered structure, so it is not easy to come out from the lower end of the first through hole 131 when the first through hole 131 and the second through hole 142 are inserted from top to bottom.

[0022] Example 2: Further explanation in conjunction with Example 1; This embodiment is a further optimized design based on Embodiment 1. Repeated content will not be described here; only the differences from Embodiment 1 will be described. These differences are as follows: In a preferred embodiment, an inclined connecting rod 4 is provided between the two uprights 12. A detachable second connecting member 16 is provided on the connecting plate 13 corresponding to both ends of the inclined connecting rod 4. A first shaft 21 connected to the horizontal connecting rod 3 and a second shaft 22 connected to the inclined connecting rod 4 are hinged on the second connecting member 16.

[0023] Using the above structure, the oblique connecting rod 4 includes a third rod 41 connected to one side connecting plate 13, a fourth rod 42 connected to the other side connecting plate 13, and a second adjusting rod 43 disposed between the third rod 41 and the fourth rod 42. Here, the oblique connecting rod 4 has a similar structure to the horizontal connecting rod 3, and the principle of adjusting the spacing is the same, so it will not be described again here. Setting the oblique connecting rod 4 can further improve the connection strength between the two uprights 12. The connection method between the first shaft 21, the second shaft 22 and the second connecting piece 16 can be welding or threaded connection.

[0024] In a preferred embodiment, a groove 162 is provided on the side where the second connector 16 is connected to the inclined connecting rod 4. A first crossbar 18 and a second crossbar 19 are provided in the groove 162 along the height direction. One of the first shaft 21 and the second shaft 22 is hinged to the first crossbar 18, and the other is hinged to the second crossbar 19.

[0025] With the above structure, the horizontal connecting rod 3 and the diagonal connecting rod 4 can be arranged in one plane. This allows for the addition of a diagonal connecting rod 4 when the distance between the two horizontal connecting rods 3 connecting the two uprights 12 is large, thereby improving the connection strength of the entire adjustable disc-lock scaffold.

[0026] In a preferred embodiment, a third through hole 161 is provided on the second connector 16, and a second pin 17 for fixing the connecting plate 13 and the second connector 16 is provided in the third through hole 161 and the first through hole 131.

[0027] With the above structure, during installation, the third through hole 161 and the first through hole 131 can be aligned first, and then the second pin 17 can be inserted into the third through hole 161 and the first through hole 131 to fix the second connector 16 onto the connecting plate 13.

[0028] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
