Description

Technical Field

[0001] The utility model belongs to the technical field of fixing devices, in particular to a safety belt fixing device for a scaffolding upright pole. Background Art

[0002] During the scaffolding construction process, the vertical pipes are built first, and then the horizontal pipes are built. When the workers hang the safety belts, they often hang them on the horizontal pipes that have been built nearby. Therefore, when the workers build the scaffolding, they are always unable to achieve the use requirements of the safety belts hanging high and using low. Even if the safety belts can hang the workers after an accident, because the safety belts are near the workers when they are hung, after the accident, the safety belts need to be lowered to a certain height to play a role. Therefore, due to the height difference when the safety belts are used, the workers will still fall a certain distance, which will cause injuries to the workers. Utility Model Content

[0005] Preferably, the locking member includes an insertion rod portion, the length of the insertion rod portion is greater than the diameter of the lower tube body, one end of the insertion rod portion is fixedly connected to the circular plate portion, and the other end of the insertion rod portion forms a through hole, which is used in conjunction with a safety pin.

[0006] Preferably, the plurality of lower tube holes are evenly arranged along the axial direction of the lower tube body, and a tapered portion is formed at the bottom of the lower tube body.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, by Figure 1-5The utility model relates to a safety belt fixing device for a scaffolding upright pole, comprising a lower tube body 1 and an upper tube body 2 matched with the lower tube body 1, wherein a tube groove 101 is formed inside the lower tube body 1, and a plurality of lower tube holes 102 are formed on the outer wall of the lower tube body 1, the upper tube body 2 is connected to a ring body 3, and an upper tube hole 201 is formed on the outer wall of the upper tube body 2, and the upper tube hole 201 on the upper tube body 2 is locked with the lower tube hole 102 on the lower tube body 1 by a locking member 4;

[0022] With this design, the device has two working states when in use, as follows:

[0023] The first working state: reference Figure 4 When the steel pipe 5 is at a higher position, since the height of the steel pipe 5 itself is relatively high, the device does not need to be set at a long distance. It can be used by simply passing the locking member 4 through the upper tube hole 201 of the upper tube body 2 and the lower tube hole 102 on the lower tube body 1, so that the lower tube body 1 can be basically inserted into the interior of the steel pipe 5. The safety belt of the staff can be hung on the ring body 3 through the hook to meet the requirement of high hanging and low use of the safety belt;

[0024] The second working state: reference Figure 5 When the steel pipe 5 is at a lower position, the lower tube body 1 is partially inserted into the interior of the steel pipe 5, and then another locking piece 4 is installed in the middle of the lower tube body 1 to prevent the lower tube body 1 from continuing to descend; the staff's safety belt can be hung on the ring body 3 through a hook to meet the requirements of high hanging and low use of the safety belt.

[0025] The locking member 4 includes a rod portion 401, the length of which is greater than the diameter of the lower tube 1, one end of which is fixedly connected to a circular plate portion 402, and the other end of which forms a through hole 403, which is used in conjunction with a safety pin 404;

[0026] This design makes it easy to lock the free end of the insertion rod portion 401 through the safety pin 404 to prevent it from being disengaged during use.

[0027] A plurality of lower tube holes 102 are evenly arranged along the axial direction of the lower tube body 1, and a tapered portion 103 is formed at the bottom of the lower tube body 1;

[0028] Such a design makes it easier for the lower tube body 1 to be inserted into the interior of the steel tube 5 through the tapered portion 103 .

[0029] The upper tube body 2 and the ring body 3 are fixedly connected.

[0030] The upper tube body 2 is rotatably connected to the ring body 3;

[0031] With such a design, when the user drives the ring body 3 to rotate through the hook on the safety belt, the ring body 3 can also rotate, thereby preventing the safety belt from being entangled.

[0032] The bottom radius of the upper tube body 2 is greater than the middle radius of the upper tube body 2, and the shape of the tube groove 101 matches the shape of the upper tube body 2;

[0033] Such a design can improve the stability of the upper tube body 2 when sliding inside the tube groove 101 .
