[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention.

[0025] Please refer to Figure 1-5 As shown, a waterproof construction device suitable for screw holes in exterior walls comprises: a barrel 1 with a hollow accommodating cavity and an opening at one end, a brush assembly 2 is provided in the barrel 1 for repeatedly moving along its central axis direction for rotationally brushing the screw holes, a push-pull mechanism 3 is movably connected to one side of the brush assembly 2, and the push-pull mechanism 3 is provided with a stabilizing mechanism 4 for preventing the brush assembly 2 from shaking.

[0026] The above embodiment realizes fast and efficient construction of bolt eyes by means of a brush assembly 2 rotatably arranged inside the barrel 1 for rotationally brushing the screw eye, a push-pull mechanism 3 for pushing and pulling the brush assembly 2 for reciprocating rotation along the length direction of the barrel 1, and a stabilizing mechanism 4 for preventing the brush from shaking, thereby improving the quality of bolt eye painting as well as the quality and efficiency of construction.

[0027] like Figure 1 As shown, in order to facilitate the gripping of the waterproof construction device, a handle 6 is provided at the lower part of the cylinder 1 in this embodiment. The handle 6 can be as follows Figure 1 The oblique setting in the figure can also be set according to actual needs, and this application does not limit this.

[0028] like Figure 2 and 3 As shown, the brush assembly 2 includes a brush stand 21 , and a plurality of bristles 22 are fixedly arranged around the brush stand 21 .

[0029] It should be noted that the brush stand 21 in this embodiment is a cylindrical stand, which makes it easier to fix the bristles 22 on its circumference, and the outer shape is easier to fit with the bolt eyes, ensuring that the waterproof coating has a better brushing effect on it.

[0030] In order to better paint the inner wall of the bolt eye, the diameter of the circle where the outer circumference of the plurality of brush bristles 22 is located is equal to or greater than the inner diameter of the screw eye, and the greater here should be understood as slightly greater.

[0031] In order to facilitate the absorption of the waterproof coating on the bristles 22, the bristles 22 in this embodiment are made of rubber material or other materials with good adsorption of waterproof coating. It should be noted that in order to be able to better brush the inner wall of the bolt eye, the bristles 22 should have a certain hardness to facilitate the application of the waterproof coating to the inner wall of the bolt eye.

[0032] like Figure 2 and 4As shown, the push-pull mechanism 3 includes a pull rod 31 that can be pushed and pulled freely along the length direction of the cylinder 1. One end of the pull rod 31 is connected to the center of the brush stand 21, and the other end extends out of the cylinder 1 and is connected to a handle 32 located outside the cylinder 1.

[0033] It is understandable that one end of the cylinder 1 is open to facilitate the bristles 22 to enter and exit the cylinder 1, and the other end can be provided with a closed cover to facilitate the push and pull of the pull rod 31, and a through hole is provided in the center to facilitate the extension of the pull rod 31.

[0034] Considering that the brush part of the brush assembly 2 is likely to be damaged after long-term use, in order to avoid it affecting the effect of the rotary brushing of the waterproof coating. In this embodiment, the brush stand 21 and the pull rod 31 are fixed in an active manner. Since the pull rod 31 needs to rotate, in order to avoid relative rotation between the brush stand 21 and the pull rod 31. The active fixing method avoids the use of connection methods such as threads that are prone to relative rotation. A method such as a pin fixing can be used to avoid the above situation. The replaceable brush assembly 2 enables the device to be suitable for brushing waterproof coatings with bolt eyes of different inner diameters, thereby increasing the scope of use of the device and reducing costs.

[0035] like Figure 5 As shown, the stabilizing mechanism 4 includes a connecting rod 41 that vertically penetrates and is fixed to the pull rod 31 , and an arc-shaped sliding piece 42 that is fixed to both ends of the connecting rod 41 and is slidably connected to the inner wall of the cylinder 1 .

[0036] It is understandable that, since the brush assembly 2 needs to extend out of the barrel 1 when painting the bolt eye, in order to avoid the shaking of the pull rod 31 and the brush assembly 2 during rotation and brushing, which causes inconvenience in use. In this embodiment, a stabilizing mechanism 4 consisting of a connecting rod 41 and arc-shaped slides 42 at both ends is provided on the side of the pull rod 31 close to the handle 32. When the handle 32 is rotated to drive the brush assembly 2 to rotate and push and pull back and forth, the pull rod 31 can be restricted to the center of the barrel 1 due to the sliding connection between the arc-shaped slide 42 and the inner wall of the barrel 1, thereby ensuring the stability of the rotation and movement of the brush assembly 2 outside the barrel 1, and further improving the uniformity of the waterproof coating applied to the inner wall of the bolt eye.

[0037] In order to prevent the stabilizing mechanism 4 from extending out of the cylinder 1 , in this embodiment, the stabilizing mechanism 4 is provided with a pull rod 31 on one side of the cylinder 1 close to the handle 32 .

[0038] like Figure 2 As shown in Fig. 4, in order to prevent the waterproof coating on the bristles 22 from contacting the arc-shaped slide 42 of the stabilizing mechanism 4 along the inner wall of the cylinder 1, thereby increasing the friction between the arc-shaped slide 42 and the inner wall of the cylinder 1. In this embodiment, a circular baffle 5 is arranged between the brush assembly 2 and the stabilizing mechanism 4, and the circular baffle 5 is fixedly sleeved on the pull rod 31.

[0039] In order to prevent the circular baffle 5 from extending out of the cylinder 1 , the circular baffle 5 is arranged at one end of the pull rod 31 close to the stabilizing mechanism 4 in this embodiment.

[0040] The working process of this device is as follows:

[0041] Push the handle 32 to push the brush assembly 2 out of the barrel 1, and after being dipped in waterproof coating, pull the handle 32 to pull the brush assembly 2 back into the barrel 1; align the open end of the barrel 1 with the bolt eye, push and rotate the handle 32 to push the brush assembly 2 into the bolt eye, and apply the waterproof coating to the inner wall of the bolt eye. Repeat the above actions until the waterproof coating on the inner wall of the bolt eye meets the construction requirements.

[0042] The utility model realizes fast and efficient construction of bolt eyes, improves the quality of bolt eye painting, and the quality and efficiency of construction by means of a brush assembly 2 rotatably arranged inside a cylinder 1 for rotationally brushing the screw eye, a push-pull mechanism 3 for pushing and pulling the brush assembly 2 for reciprocating rotational motion along the length direction of the cylinder 1, and a stabilizing mechanism 4 for preventing the brush from shaking.

[0043] The above is a specific implementation of the embodiment of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the scope of protection of this application.
