DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A connecting sleeve in this embodiment includes a connecting sleeve body 1 and a column body 2. A connecting mechanism is arranged outside the connecting sleeve body 1, and a correction component is arranged inside the connecting sleeve body 1.

[0025] Embodiment 1: The connecting mechanism includes a first mounting seat 3 and a second mounting seat 4, both of which are fixedly connected to the connecting sleeve body 1 and are in two numbers. The two first mounting seats 3 are symmetrically distributed, and the two second mounting seats 4 are symmetrically distributed. The first mounting seat 3 and the second mounting seat 4 are symmetrical parts, which facilitates the connection between the connecting sleeve body 1 and the two column bodies 2, and is convenient for the user to connect the two column bodies 2 together using the connecting sleeve body 1. The first mounting seat 3 is internally rotatably connected with a self-locking knob 5, and the self-locking knob 5 is internally fixedly connected with a threaded screw 6 rotatably connected to the first mounting seat 3. The end of the threaded screw 6 away from the self-locking knob 5 is fixedly connected with a bearing 601, and the bearing 601 is fixedly connected to the first mounting seat 3 to limit the threaded screw 6, which facilitates the rotation of the threaded screw 6 and reduces the loss of driving force during the rotation of the threaded screw 6 through the bearing 601.

[0026] Among them, the external threaded connection of the threaded screw 6 is connected with two sliding seats 7, and a rotating hole is opened inside the first mounting seat 3. The self-locking knob 5 is rotatably connected to the first mounting seat 3 through the rotating hole, which facilitates the installation connection between the self-locking knob 5 and the first mounting seat 3. The user rotates the self-locking knob 5 to drive the threaded screw 6 to rotate, so that the two sliding seats 7 move relative to or apart from the outside of the threaded screw 6, which is convenient for the user to adjust and use. A clamping block 8 is fixedly connected to the left side of the sliding seat 7, and a clamping block 9 is fixedly connected to the opposite side of the two clamping blocks 8.

[0027] In addition, a limiting groove 201 is provided inside the column body 2, and the size of the clamping block 9 is adapted to the limiting groove 201. The two clamping blocks 8 move relative to each other, driving the two clamping blocks 9 to move relative to each other, so that the clamping block 9 is clamped with the limiting groove 201, and the column body 2 is limited, which facilitates the connection between the sleeve body 1 and the column body 2. The inside of the two clamping blocks 8 is plugged with a fixing rod 10 fixedly connected to the second mounting seat 4, and the outside of the fixing rod 10 is sleeved with a telescopic spring 11. The left side of the clamping block 8 is fixedly connected with a connecting seat 801, and the fixing rod 10 is plugged with the clamping block 8 through the connecting seat 801, so as to limit the clamping block 8, so that the clamping block 8 does not rotate with the threaded screw 6, and the relative or separate sliding of the two clamping blocks 8 is convenient.

[0028] It should be noted that by setting up a connecting mechanism, it is convenient for users to adjust and use the connecting sleeve, and it is convenient to connect the connecting sleeve to columns of different sizes, thereby improving the user's efficiency in using the connecting sleeve. It solves the problem that the connecting sleeve has a simple structure, and when using the connecting sleeve to connect with the column, it is inconvenient for the connecting sleeve to adapt to the connection of columns of different sizes, which limits the applicability and practicality of the connecting sleeve and affects the construction personnel's efficiency in using the connecting sleeve.

[0029] Specifically, during the construction of the scaffold, the user sleeves the connecting sleeve body 1 with a column body 2 and turns the self-locking knob 5. The self-locking knob 5 drives the threaded screw 6 to rotate, so that the two sliding seats 7 slide relative to each other on the outside of the threaded screw 6. The two sliding seats 7 drive the clamping blocks 8 to move relative to each other, so that the clamping blocks 9 are engaged with the limiting grooves 201 on the column body 2, and the installation of the connecting sleeve body 1 is completed. Then, the other column body 2 is plugged into the connecting sleeve body 1, and the user turns another self-locking knob 5 to complete the limiting fixation of the other column body 2, and the two column bodies 2 are connected, thereby achieving the purpose of facilitating the construction personnel to adjust and use the connecting sleeve body 1.

[0030] Example 2: Please refer to Figure 1The correction component includes two correction blocks 12 fixedly connected to the connecting sleeve body 1. A slot 202 is provided inside the column body 2. The size of the correction block 12 is adapted to the slot 202. The column body 2 is sleeved with the correction block 12 through the slot 202, which facilitates the correction installation of the column body 2 and the correction installation of the column body 2 of different sizes and the connecting sleeve body 1.

[0031] It should be noted that by providing a correction component, the correction installation of the column and the connecting sleeve is facilitated, and the use of the connecting sleeve is facilitated.

[0032] Specifically, during the process of connecting the column body 2 with the connecting sleeve body 1, the column body 2 is plugged into the connecting sleeve 1, and the card slot 202 on the column body 2 is sleeved with the correction block 12 to complete the correction of the column body 2, facilitating the installation and connection of the column body 2 with the connecting sleeve body 1.

[0033] The working principle of the above embodiment is:

[0034] (1) During the erection of the scaffold, the user sleeves the connecting sleeve body 1 with a column body 2 and rotates the self-locking knob 5. The self-locking knob 5 drives the threaded screw 6 to rotate, so that the two sliding seats 7 slide relative to each other on the outside of the threaded screw 6. The two sliding seats 7 drive the clamping blocks 8 to move relative to each other, so that the clamping blocks 9 engage with the limiting grooves 201 on the column body 2, thereby completing the installation of the connecting sleeve body 1. Then, the other column body 2 is plugged into the connecting sleeve body 1. The user rotates another self-locking knob 5 to complete the limiting fixation of the other column body 2, and the two column bodies 2 are connected, thereby achieving the purpose of facilitating the construction personnel to adjust and use the connecting sleeve body 1.

[0035] (2) During the process of connecting the column body 2 with the connecting sleeve body 1, the column body 2 is plugged into the connecting sleeve 1, and the slot 202 on the column body 2 is engaged with the correction block 12 to complete the correction of the column body 2, thereby facilitating the installation and connection of the column body 2 with the connecting sleeve body 1.
