Description

Technical Field

[0001] The utility model relates to a building repair tool, specifically an exterior wall waterproofing processor. Background Art

[0002] In the field of building maintenance, the waterproof treatment or repair of exterior walls is a key task. Traditional methods for exterior wall waterproof treatment usually require workers to hang a hanging basket from the roof using ropes for operation. This method has relatively high safety risks and is costly. For example, regardless of the repair area size, the cost of the hanging basket for a single operation can be as high as 500 yuan. A Japanese utility model patent with the publication number JP2023152230A proposes an exterior wall repair device and an exterior wall repair method. The device includes a walking part on the roof, a hanging and lifting trolley, and a manipulator in the hanging basket. The repair area is photographed by a photographing unit, and the hanging basket is fixed to the exterior wall surface using a fixing device. The device also includes a remote operation part equipped with a monitor and gloves for the operator to operate, to achieve synchronous remote operation of the manipulator. Although the device of this patent does not require personnel to enter the hanging basket, thus having some innovation in improving operation safety, there are still some deficiencies: First, the device still needs to set up a hanging basket, which is not cost-effective for small-area repair work. Second, the operation process is relatively complex and lacks intuitiveness, increasing the operation difficulty. Finally, the structure of the device is relatively complex, which may lead to inconvenience in maintenance and repair. Summary of the Utility Model

[0003] In view of the limitations of the prior art, the utility model aims to provide a more economical, practical, easy-to-install and maintain exterior wall waterproof treatment solution, making the exterior wall waterproof treatment more convenient and economical. The technical solution adopted by the utility model is as follows:

[0004] An exterior wall waterproofing processor, in addition to including a commercially available waterproof agent spray can, further includes

[0005] a telescopic rod composed of 2 or more than 2 sleeves, with a maximum length of 3m;

[0006] a first fixing seat, including a first sleeve adapted to be sleeved on the telescopic rod near the top end, and a top-tightening screw is radially screwed on the first sleeve to fix it on the telescopic rod, and a tray for supporting the waterproof agent spray can is fixedly connected to the first sleeve;

[0007] a second fixing seat, located above the first fixing seat, including a second sleeve adapted to be sleeved on the telescopic rod, and a top-tightening screw is radially screwed on the second sleeve to fix it on the telescopic rod, and a rectangular slot is fixedly connected to the second sleeve. The rectangular slot communicates with the inner cavity of the second sleeve through a window, and a first long hole is opened on the telescopic rod corresponding to the window;

[0008] The U-shaped body is obliquely inserted into the rectangular slot, with its front and bottom open. On both sides of the bottom opening, flanges extend inward respectively, and counterbored through holes are provided on the inner surface.

[0009] The wedge-shaped body directly or indirectly abuts against the pressing head of the waterproof agent spray can at the bottom, directly or indirectly abuts against the inner top surface of the U-shaped body at the top. On the upper parts of both side surfaces, limiting strips extend outward. The limiting strips are inserted into the U-shaped body and are in clearance fit. The lower parts of both side surfaces are in clearance fit with the flanges, and counterbored blind holes are provided on the inner end surfaces.

[0010] The spray trigger includes a pipe clamp sleeved on the telescopic rod near the bottom end. Both ends of the pipe clamp are locked by bolts and an L-shaped handle is hinged at the same time. A deep-groove pulley is rotatably arranged at the upper end of the handle, and a rope-end fixing nut is screwed at the middle part of the handle. A long slot two is provided on the telescopic rod corresponding to the deep-groove pulley.

[0011] Two deep-groove steering balls are rotatably arranged inside the telescopic rod, corresponding to the long slot one and the long slot two respectively.

[0012] The steel wire rope has its upper end located in the counterbored blind hole and fixed to the wedge-shaped body, and its lower end sequentially passes through the counterbored through hole, the long slot one, bypasses the two deep-groove steering balls, passes through the long slot two, bypasses the deep-groove pulley, and is finally fixed to the handle by the rope-end fixing nut.

[0013] The spring has its two ends respectively embedded in the counterbores of the counterbored blind hole and the counterbored through hole, and allows the steel wire rope to pass through it.

[0014] Furthermore, a wide-angle spherical mirror is also included, which is fixedly connected to the top end of the telescopic rod through an adjustable curvature bracket and a rotatable ball head.

[0015] Furthermore, a baffle is fixedly arranged on the front end face of the U-shaped body.

[0016] Furthermore, the tightening screw screwed to the sleeve one is a butterfly screw so as to quickly adjust the position of the sleeve one on the telescopic rod to adapt to waterproof agent spray cans of different sizes; the rope-end fixing nut is a butterfly nut so as to quickly adjust the tension of the steel wire rope to adapt to the telescopic rod being adjusted to different lengths in different usage scenarios.

[0018] Further, shallow grooves are formed on the upper and lower surfaces of the wedge-shaped body. Axial holes are densely formed on both side walls of the shallow grooves. A first slope is formed on the side wall above the axial holes. The two ends of the needle roller are tapered to form roller shafts. The half-width of the end of the roller shaft is also obliquely cut to form a second slope. The distance between the two ends of the roller shaft is slightly greater than the width of the shallow groove. When pressing the middle of the needle roller with a finger, the needle roller is bent and deformed, the distance between the two ends of the roller shaft becomes smaller and it moves downward. After releasing the hand, the needle roller returns to its original state. The two ends of the roller shaft are respectively embedded in the axial holes and are in clearance fit with them and cannot be disengaged.

[0019] Further, external threads are formed at the upper end of the outer tube of the telescopic rod and a plurality of telescopic slits are axially formed. A rotary locking sleeve with a conical inner cavity is screwed to the outer tube, allowing the user to quickly adjust the length of the telescopic rod through a rotating action and ensuring the stability of the telescopic rod during operation.

[0020] Further, anti-slip textures or cushions are provided in the sleeves of the first fixing seat and the second fixing seat to increase the friction with the telescopic rod and prevent sliding during use.

[0021] Further, a hook is connected to the lower end of the handle, and the hook can be hooked on the telescopic rod.

[0022] Further, an isolation sheet is clamped between the lower surface of the wedge-shaped body and the pressing head of the waterproof agent spray can.

[0049] An exterior wall waterproof processor as shown in the attached drawings includes

[0050] The waterproofing agent spray can 100 is a commercially available product widely used in building maintenance and waterproofing treatment. The spray can is designed with a preset pressure tank that can efficiently spray the waterproofing agent evenly on the target surface in an atomized form. The waterproofing agent contained in the spray can can be water-based or in latex form, with various formulations to meet the waterproofing needs of different materials and environmental conditions;

[0051] The telescopic rod 1 is composed of two or more than two sections of sleeves, with a maximum length of 3m; it is composed of two or more nested sleeves to achieve length adjustability. This design allows users to easily adjust the length of the telescopic rod according to actual needs to adapt to the waterproofing treatment tasks of exterior walls at different heights. The length of 3m is sufficient to cover the exterior wall maintenance work of most low-rise buildings, and it is also convenient for users to operate on the ground or at the window, reducing the need to use ladders or other auxiliary equipment. This design of the telescopic rod not only improves the convenience and safety of operation but also increases the applicable range and flexibility of the equipment. It is especially suitable for high-rise buildings and construction by reaching out of the window indoors.

[0052] The first fixing seat 2 includes a first sleeve 21 adapted to be sleeved on the telescopic rod 1 near the top. The first sleeve 21 is radially screwed with a tightening screw to fix it on the telescopic rod 1. The first sleeve 21 is fixedly connected to a tray 22 that supports the waterproofing agent spray can 100; it plays a role in connecting with the telescopic rod 1 and supporting the waterproofing agent spray can 100. The first sleeve 21 is fixed to the telescopic rod 1 by a radially screwed tightening screw. This design allows users to adjust the position of the first sleeve 21 on the telescopic rod 1 according to needs to ensure that the spray can 100 can be operated at an ideal height. The size and shape of the tray 22 match the spray can 100 to ensure that the spray can can be stably placed on the tray, facilitating the operator's control and use. The design of the first fixing seat 2 takes into account the stability during operation to ensure that even when the telescopic rod 1 is extended to the maximum length, the spray can 100 can remain stable, avoiding uneven spraying caused by shaking or instability. Through the design of the first fixing seat 2, the operator can easily install the waterproofing agent spray can 100 on the telescopic rod 1 and quickly adjust its position according to needs, improving the convenience and efficiency of operation.

[0053] The second fixing seat 3 is located above the first fixing seat 2 and includes a second sleeve 31 adapted to be sleeved on the telescopic rod 1. The second sleeve 31 is radially screwed with a tightening screw to fix it on the telescopic rod 1. The second sleeve 31 is fixedly connected to a rectangular slot 32, and the rectangular slot 32 communicates with the inner cavity of the second sleeve 31 through a window 33. A long hole 11 is opened on the telescopic rod 1 corresponding to the window 33; the second fixing seat 3 provides a structural support for remotely controlling the pressing head of the waterproofing agent spray can 100.

[0054] The U-shaped body 4 is inserted obliquely into the rectangular slot 32, with its front and bottom open, and the two sides of the bottom opening extend inward to form blocking wings 41, and a countersunk through hole 42 is provided on the inner surface; in order to improve the firmness of its insertion with the rectangular slot 32, as shown in FIG. Figure 3 As can be seen, there is a self-tapping screw connecting them. The front and bottom of the U-shaped body 4 are designed as an open structure, which is convenient for the assembly of the wedge-shaped body 5.

[0055] The wedge-shaped body 5 directly or indirectly abuts against the pressing head of the waterproofing agent spray can 100 at the bottom, and directly or indirectly abuts against the inner top surface of the U-shaped body 4 at the top. The upper parts of the two side surfaces extend outward to form limit strips 51, which are inserted into the U-shaped body 4 and are clearance-matched. The lower parts of the two side surfaces are clearance-matched with the retaining wings 41, and the inner end surface is provided with a countersunk blind hole 52. The wedge-shaped body 5 converts the horizontal pulling force into the vertical thrust through its structural design. This conversion is usually achieved through the angle and shape of the wedge-shaped body, so that when the wedge-shaped body is subjected to a horizontal pulling force, its inner end surface generates a force perpendicular to the surface of the wedge-shaped body, and the working principle is similar to the lever principle. The inner end surface of the wedge-shaped body 5 is designed to be tightly matched with the pressing head of the waterproofing agent spray can 100. When the wedge-shaped body is subjected to a horizontal pulling force, it directly or indirectly applies pressure to the pressing head of the spray can, thereby triggering the spray can to release the waterproofing agent. The moving distance and speed of the wedge-shaped body 5 can be precisely controlled by operating the spray trigger 6, thereby precisely controlling the pressing force and duration of the pressing head of the waterproofing agent spray can 100.

[0056] The spraying trigger 6 comprises a pipe clamp 61 sleeved on the telescopic rod 1 near the bottom end, the two ends of the pipe clamp 61 are locked by bolts and an L-shaped handle 62 is hinged at the same time, the upper end of the handle 62 is rotated to set a deep groove pulley 63, and the middle part of the handle 62 is screwed to the rope end fixing nut 64; a long hole 12 is provided on the telescopic rod 1 corresponding to the deep groove pulley 63; the design of the spraying trigger 6 provides a simple and direct method to control the spraying of the waterproofing agent, so that the operator can operate safely and accurately away from the wall.

[0057] Two deep groove steering balls 7 are arranged inside the telescopic rod 1, corresponding to the long strip hole 11 and the long strip hole 2 12 respectively; the main function of the deep groove steering balls 7 is to change the pulling direction of the wire rope 8 when the wire rope passes through them. The deep groove provides a path around the wire rope, which helps to keep the wire rope on the predetermined track and reduce the risk of escape due to deviation from the track. The spherical deep groove steering ball can perfectly fit with the inner wall of the telescopic rod. The wire rope 8 has no additional space deflection when passing through the steering ball, ensuring that the wire rope moves accurately along the predetermined path and reducing the swing of the wire rope during movement. The guiding accuracy of the wire rope is improved, ensuring stability and reliability during operation.

[0058] The steel wire rope 8 has its upper end located within the countersunk blind hole 52 and fixedly connected to the wedge-shaped body 5. The lower end sequentially passes through the countersunk through hole 42, the first elongated hole 11 from top to bottom, bypasses 2 deep-groove steering balls 7, passes through the second elongated hole 12, bypasses the deep-groove pulley 63, and is finally fixed to the handle 62 by the rope-end fixing nut 64.

[0059] The spring 9 has its two ends respectively embedded in the countersinks of the countersunk blind hole 52 and the countersunk through hole 42, and allows the steel wire rope 8 to pass through it. The two ends of the spring 9 are respectively embedded in the countersinks of the countersunk blind hole 52 of the wedge-shaped body 5 and the countersunk through hole 42 of the U-shaped body 4. This embedding method ensures the stable installation of the spring in the structure. The spring 9 allows the steel wire rope 8 to pass through it. The spring provides a path for the steel wire rope, and the steel wire rope in turn provides a clear movement path for the spring, restricting the movement range of the spring and preventing the spring from bending due to excessive stretching or compression. When the spray trigger 6 is loosened, the elastic force of the spring 9 causes the wedge-shaped body 5 to quickly return to its initial position. This quick reset function is crucial for improving the operation efficiency and response speed.

[0060] The overall working process is described as follows:

[0061] Preparation stage: Place the commercially available waterproofing agent spray can 100 on the tray 22 of the first fixed seat 2 and fix it to the top end of the telescopic rod 1 by the tightening screw.

[0062] Telescopic rod adjustment: According to the height of the exterior wall to be sprayed, adjust the telescopic rod to the appropriate length through the locking mechanism between the sleeves on the telescopic rod 1.

[0063] Wedge-shaped body positioning: The wedge-shaped body 5 is positioned by the clearance fit with the gap within the U-shaped body 4 through the limiting strip 51, and it is ensured that the lower end of the wedge-shaped body can directly or indirectly abut against the pressing head of the waterproofing agent spray can 100.

[0064] Spray trigger preparation: The spray trigger 6 is fixed to the bottom end of the telescopic rod 1 by the pipe clamp 61, and the L-shaped handle 62 is ready for operation.

[0065] Steel wire rope and spring setting: The upper end of the steel wire rope 8 is fixed within the countersunk blind hole 52 of the wedge-shaped body 5, and the lower end passes through the countersunk through hole 42 of the U-shaped body 4, passes through the first elongated hole 11 and the second elongated hole 12 on the telescopic rod 1, bypasses the deep-groove steering balls 7 and the deep-groove pulley 63, and is finally fixed to the rope-end fixing nut 64 on the handle 62.

[0066] Spring 9 installation: The two ends of the spring 9 are embedded within the countersunk blind hole 52 of the wedge-shaped body 5 and the countersunk through hole 42 of the U-shaped body 4, and the steel wire rope passes through it, providing the wedge-shaped body 5 with the ability to quickly reset.

[0067] Operation process: The operator holds the L-shaped handle 62 of the spray trigger 6 at the ground or window and controls the tension of the wire rope 8 by pulling or pushing the handle. When the handle 62 is pulled, the wire rope 8 transmits the pulling force through the deep groove pulley 63 and the rope end fixing nut 64, causing the wedge body 5 to move downward, thereby pressing the pressing head of the waterproof agent spray can 100 to release and spray the waterproof agent. Through the length adjustment of the telescopic rod 1 and the support of the fixed seat, the operator can perform precise spraying at different heights and angles.

[0068] Reset process: When the handle 62 is released, the elastic force of the spring 9 causes the wedge body 5 to quickly return to the initial position, preparing for the next spraying operation.

[0069] End operation: After completing the spraying task, the operator retracts the telescopic rod 1 to the shortest length, disconnects the trigger 6 from the wire rope 8, and stores the equipment properly.

[0070] Through this series of steps, the exterior wall waterproofing processor realizes efficient, safe and user-friendly waterproof agent spraying operations, which are suitable for the exterior wall maintenance and waterproofing treatment tasks of various low-rise and high-rise buildings.

[0071] In another preferred embodiment, it further includes a wide-angle spherical mirror 10, which is fixedly connected to the top end of the telescopic rod 1 through an adjustable curvature bracket 101 and a rotatable ball head 102. Such an installation position makes the spherical mirror located above or beside the waterproof agent spray can 100, and the operator can observe the condition of the area to be repaired through the reflection of the wide-angle spherical mirror 10. The reflection of the spherical mirror enables the operator to clearly see the operation area without getting too close to the wall. The adjustable curvature bracket 101 allows the operator to adjust the curvature of the spherical mirror according to needs to change the reflection angle and observation range to adapt to different observation distances and viewing angle requirements. The rotatable ball head 102 provides additional flexibility, enabling the spherical mirror to rotate in the horizontal and vertical directions, further expanding the observation range. Before the waterproof agent spraying operation, the operator adjusts the adjustable curvature bracket 101 and the rotatable ball head 102 to ensure that the spherical mirror is aligned with the area to be repaired. By observing the reflected image in the spherical mirror, the operator can evaluate the spraying position and coverage range to ensure that the waterproof agent is evenly sprayed on the target area. During the spraying process, the operator can observe and adjust the positions of the telescopic rod 1 and the wedge body 5 in real time, and make fine adjustments according to the feedback in the spherical mirror to achieve a more precise spraying effect.

[0072] In another preferred embodiment, a baffle 103 is fixedly arranged on the front end face of the U-shaped body 4. The baffle provides a physical barrier to ensure that the wedge body remains in the predetermined position of the U-shaped body and can prevent the wedge body 5 from slipping out. The assembled baffle is easy to inspect and maintain, and its condition can be regularly checked and cleaned or replaced to maintain good working conditions.

[0073] In another preferred embodiment, the tightening screw screwed to the first sleeve 21 is a butterfly screw so as to quickly adjust the position of the first sleeve 21 on the telescopic rod 1 to adapt to waterproof agent spray cans 100 of different sizes; the rope end fixing nut 64 is a butterfly nut so as to quickly adjust the tension of the steel wire rope to adapt to the telescopic rod 1 being adjusted to different lengths in different usage scenarios. The design of the butterfly screw and the butterfly nut allows the user to quickly make adjustments without using tools and can be tightened or loosened manually, greatly improving the operation efficiency. By using the butterfly screw to be screwed to the first sleeve 21, the position of the first sleeve on the telescopic rod 1 can be easily adjusted to adapt to waterproof agent spray cans 100 of different sizes, ensuring that the spray can can be stably installed at an appropriate height. The rope end fixing nut 64 adopts the design of a butterfly nut, making it simple and fast to adjust the tension of the steel wire rope 8. The user can finely adjust the tension of the steel wire rope as needed.

[0074] In another preferred embodiment, a retaining edge 23 larger than the diameter of the waterproof agent spray can 100 extends upward from the upper surface of the tray 22, and a reinforcing rib 24 is provided between the lower surface of the tray 22 and the first sleeve 21. The retaining edge design can prevent the spray can from rolling or slipping on the tray, improving the placement stability. It can serve as an auxiliary edge when the operator loads and unloads the spray can, facilitating the operator to pick up and place the spray can. The reinforcing rib structure enhances the load-bearing capacity of the tray, enabling it to better support the weight of the waterproof agent spray can 100.

[0075] In another preferred embodiment, shallow grooves 54 are formed on the upper and lower surfaces of the wedge 5, axial holes 55 are densely formed on both side walls of the shallow grooves 54, a first slope 56 is formed on the side wall above the axial holes 55, both ends of the needle roller 53 are tapered to form roller shafts 57, and half of the end of the roller shaft 57 is also obliquely cut to form a second slope 58. The distance between both ends of the roller shaft 57 is slightly larger than the width of the shallow groove 54. When pressing the middle of the needle roller 53 with a finger, the needle roller 53 is bent and deformed, the distance between both ends of the roller shaft 57 becomes smaller and it moves downward. After releasing the hand, the needle roller 53 returns to its original state, and both ends of the roller shaft 57 are respectively inserted into the axial holes 55 and are in clearance fit therewith and cannot fall out. The purpose of adding the needle roller is to replace sliding friction with rolling friction, which can significantly reduce the friction force between moving parts, thereby reducing the required operating force. This makes the operation smoother. The structural design of the needle roller makes the assembly more convenient.

[0076] In another preferred embodiment, external threads are formed at the upper end of the outer tube of the telescopic rod 1 and a plurality of telescopic slits are axially formed. A rotary locking sleeve with a conical inner cavity is screwed to the outer tube, allowing the user to quickly adjust the length of the telescopic rod through a rotary action and ensuring the stability of the telescopic rod during operation.

[0077] In another preferred embodiment, the sleeves of the first fixing seat 2 and the second fixing seat 3 have anti-slip textures or cushions to increase the friction with the telescopic rod 1 and prevent sliding during use.

[0078] In another preferred embodiment, a hook is connected to the lower end of the handle 62, and the hook can be hooked on the telescopic rod 1. This allows the user to hang the handle on the telescopic rod when needed, thus releasing the hand and avoiding fatigue caused by long-term continuous gripping. At the same time, it can be conveniently retrieved when quick operation recovery is required.

[0079] In another preferred embodiment, an isolation sheet is clamped between the lower surface of the wedge 5 and the pressing head of the waterproof agent spray can 100 to prevent the waterproof agent from contaminating the wedge 5 or the rolling needle.

[0080] Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.

[0081] Matters not described in detail in the present utility model are the prior art or common general knowledge in the art.
