Description

Technical Field

[0001] This utility model relates to the field of wall decoration technology, and in particular to a wall plastering and leveling device for wall decoration. Background Technology

[0002] Plastering refers to a wall that has been plastered with lime or cement mortar. During the plastering process, the lime is usually applied to the wall by hand with a trowel, and then the lime is smoothed with the trowel. After the plastering is completed, the wall surface can be painted white.

[0003] Before plastering, rectangular holes such as socket holes or indoor light switch holes are reserved on the wall. When plastering manually, it is necessary to deliberately avoid the rectangular holes. Manually avoiding the rectangular holes will affect the overall efficiency of the plastering work. If the rectangular holes are filled with lime or cement mortar, it will directly affect the subsequent installation of sockets and indoor light switches. In severe cases, sockets and indoor light switches may not be able to be installed. Utility Model Content

Detailed Implementation

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] A wall plastering and smoothing device for wall decoration, such as Figures 1-7 As shown, the device includes a housing 1, with a handle 2 fixedly installed on one side of the housing 1, and a brake shaft 4. Several brake shafts 4 are slidably connected inside the housing 1. The top of each brake shaft 4 is connected to a first spring, which is in a contracted state. Flexible fabric 10 is fixedly installed at the bottom of each brake shaft 4, and the flexible fabric 10 is rotatably connected to the housing 1. The bottom of each brake shaft 4 is spherical. A sealing plate 5 is slidably connected inside each brake shaft 4. The brake shaft 4 has an upper inclined surface inside, which cooperates with the sealing plate 5. The sealing plate 5 is slidably connected to the housing 1. A delay mechanism is provided inside the housing 1, which can cooperate with the brake shaft 4.

[0023] The delay mechanism includes friction wheels 6. Several friction wheels 6 are movably connected inside the housing 1. One end of a first pull rope 7 is connected to the friction wheel 6 via a swivel ring. The other end of the first pull rope 7 is fixedly connected to the sealing plate 5. The first pull rope 7 is slidably connected to the housing 1. A friction zone 101 is opened inside the housing 1. Several friction wheels 6 are located in the friction zone 101. The top of the friction zone 101 has a large friction, while the top right side of the friction zone 101 does not have friction. Several friction wheels 6 are in contact with the top of the friction zone 101. A roller 3 is rotatably connected to the bottom of the inner wall of the housing 1.

[0024] The delay mechanism also includes a push rod 8. Several push rods 8 are slidably connected inside the housing 1. One end of the push rod 8 is an inclined surface. The brake shaft 4 has a lower inclined surface inside. The inclined surface of the push rod 8 cooperates with the lower inclined surface of the brake shaft 4. A push body 9 is fixedly installed at the other end of the push rod 8. A second spring is connected between the top of the push rod 8 and the inner wall of the housing 1.

[0025] It also includes a leveling component 14, which is fixedly installed on one side of the housing 1. The leveling component 14 is tilted to both sides, and the cement mortar can be guided by the leveling component 14. Conveying pipes 16 are fixedly installed on both sides of the leveling component 14. A scraper 15 is fixedly installed at the bottom of several sealing plates 5. The scraper 15 is adapted to the tilt of the leveling component 14.

[0026] It also includes a pull plate 11, which is slidably connected inside the housing 1. A third spring connects the pull plate 11 to the housing 1. A storage area 102 is provided inside the housing 1. One end of a second pull rope 12 is fixedly installed on one end of the pull plate 11. The other end of the second pull rope 12 slides through the storage area 102 and is fixedly installed with a multi-stage telescopic plate 13. The multi-stage telescopic plate 13 is slidably connected to the storage area 102. A conveying pipe 16 is connected to the storage area 102. The conveying pipe 16 can guide the collected cement mortar into the storage area 102. A slot is provided on the outer wall of the housing 1. A block 17 is slidably connected to one side of the pull plate 11. The block 17 is slidably connected to the housing 1. The block 17, in conjunction with the slot, can restrict the movement of the pull plate 11. A discharge port is provided at the bottom of the housing 1.

[0027] When preparing for plastering the wall, first pull the locking block 17 to align it with the slot. Then pull the locking block 17 upwards, causing it to slide into the slot and restricting the movement of the pulling plate 11. At this time, the third spring is in a contracted state. Next, remove the multi-stage telescopic plate 13 from the storage area 102 and fill the storage area 102 with an appropriate amount of cement mortar. Then place the multi-stage telescopic plate 13 on the top of the inner wall of the storage area 102, ensuring that the bottom of the multi-stage telescopic plate 13 is in contact with the cement mortar. Then, manually hold the handle 2, ensuring that the side of the housing 1 with the rollers 3 faces the wall and that the rollers 3 and brake shaft 4 are in contact with the wall. Then, push the locking block 17 downwards to release the restriction on the pulling plate 11. The third spring begins to release, pushing the pulling plate 11 to slide. The pulling plate 11 pulls the multi-stage telescopic plate 13 through the second pull rope 12. The multi-stage telescopic plate 13 moves downwards within the storage area 102, compressing the cement mortar. Cement mortar is discharged from the discharge port at the bottom of the casing 1. The discharged cement mortar is sprayed onto the wall surface. Then, the casing 1 is pushed forward by the handle 2. The casing 1 drives the leveling component 14 to move synchronously. The forward movement of the leveling component 14 can level the cement mortar sprayed onto the wall surface, thus carrying out the plastering operation. When the leveling component 14 is leveling the cement mortar, the tilted sides of the leveling component 14 can guide excess cement mortar to the two conveying pipes 16 on both sides, where it is collected. As more and more cement mortar is collected in the conveying pipes 16, the cement mortar will be squeezed against each other inside the conveying pipes 16. Since the cement mortar enters the conveying pipes 16 from below, the cement mortar below will squeeze the cement mortar above and move it upward. Then, the cement mortar above will move through the top of the conveying pipes 16 to the storage area 102, thus avoiding waste of excess cement mortar. It is worth noting that from Figure 2 As can be seen, the connection between the conveying pipe 16 and the storage area 102 is inclined downwards. This condition can prevent the cement mortar sprayed downwards from the storage area 102 from entering the conveying pipe 16.

[0028] Before plastering, rectangular holes are pre-drilled in the wall surface. During manual plastering, workers must deliberately avoid these holes and prevent cement mortar from being sprayed into them. This manual avoidance of the rectangular holes affects the overall efficiency of the plastering process. Therefore, a brake shaft 4 is installed inside the housing 1 to detect the position of the rectangular holes. The specific working principle is as follows:

[0029] Since there are several brake shafts 4, and in actual use, not all of them will move, we will take the two middle brake shafts 4 as an example. The operator holds the handle 2 and pushes the housing 1 to perform plastering. When the housing 1 moves to the rectangular hole position, and the two middle brake shafts 4 are above the rectangular hole, the first spring at the top of the two middle brake shafts 4 is released, pushing the two middle brake shafts 4 into the rectangular hole. During the movement of the brake shafts 4, the flexible fabric 10 will rotate downwards. At the same time, the upper inclined surface of the brake shaft 4 contacts the inclined surface of the sealing plate 5, squeezing the sealing plate 5 towards the discharge port of the housing 1. The movement of the sealing plate 5 pulls the friction wheel 6 via the first pull rope 7, causing the friction wheel 6 to move to the left side of the friction area 101. Simultaneously, the sealing plate 5 drives the bottom scraper 15 to move synchronously. When the bottom end of the brake shaft 4 contacts the bottom of the rectangular hole, the brake shaft 4 stops moving. At this time, the inside of the housing 1 is... Figure 7 In the current state, the sealing plate 5 blocks the discharge port, and cement mortar no longer discharges from the discharge port corresponding to the rectangular hole. The friction wheel 6 is pulled by the first pull rope 7 and the sealing plate 5. There is a certain gap between the friction wheel 6 and the roller 3. The scraper 15 contacts one side of the leveling part 14. Figure 5 As can be seen, the sealing plate 5 is inverted L-shaped, with vertical plates at the bottom of the sealing plate 5 positioned on both sides. These vertical plates prevent the cement mortar sprayed on both sides from entering the vertical plates when one or more sealing plates 5 move. At the same time, scrapers 15 are provided at the bottom of the vertical plates on both sides. These scrapers can level the cement mortar that the leveling component 14 has not yet leveled when the sealing plate 5 moves, and remove the excess cement mortar. When the scraper 15 comes into contact with the leveling component 14, the leveling component 14 needs a certain amount of time to guide the cement mortar, which may cause the leveling component 14 to push the cement mortar into the rectangular hole. The operation of the scraper 15 can remove the excess cement mortar, preventing it from entering the rectangular hole.

[0030] As the housing 1 moves, the flexible fabric 10 will contact the side corner of the rectangular hole and be squeezed by it. After being squeezed, the flexible fabric 10 will gradually retract into the housing 1 and bend. The gradual retraction of the flexible fabric 10 can slowly lift the brake shaft 4 upward and cause the first spring to slowly contract. As the housing 1 moves, the distance between the side corner of the rectangular hole and the brake shaft 4 gets closer and closer. When the flexible fabric 10 is completely retracted into the housing 1, the side corner of the rectangular hole will contact the bottom spherical end of the brake shaft 4 and squeeze it. After being squeezed, the bottom end of the brake shaft 4 will move upward. Subsequently, the brake shaft 4 will completely disengage from the rectangular hole and complete its reset. Through the above actions, it is possible to avoid spraying cement mortar into the rectangular hole without deliberately avoiding it during plastering.

[0031] from Figure 2 As can be seen, the brake shaft 4 is located to the right of the sealing plate 5 and the discharge port. The housing 1 can only operate normally by moving to the right. Therefore, due to the position of the brake shaft 4, the sealing plate 5, and the discharge port, as well as the working state of the housing 1 moving to the right, a problem arises: after the brake shaft 4 is reset, the discharge port of the housing 1 is still above the rectangular hole. If the discharge port is opened at this time, the discharged cement mortar will also be sprayed into the rectangular hole. To avoid this problem, a delay mechanism is designed, the working principle of which is as follows:

[0032] When the bottom end of the brake shaft 4 is pressed by the side corner of the rectangular hole, the lower inclined surface of the brake shaft 4 will contact the inclined surface of the push rod 8, pushing the push rod 8 towards the friction wheel 6. At this time, the second spring contracts, and the push rod 8 drives the push body 9 to move synchronously, pushing the friction wheel 6 through the push body 9, causing the friction wheel 6 to move within the friction zone 101 and contact the roller 3. It is worth noting that through... Figure 7It can be seen that after the sealing plate 5 blocks the discharge port of the housing 1, a portion remains on the left side. Therefore, at this time, the friction wheel 6 moves, and the sealing plate 5 is moved by the first pull rope 7, while the discharge port remains blocked. After the friction wheel 6 contacts the roller 3, the housing 1 is manually pushed to move. Since the roller 3 is in contact with the wall, the roller 3 can rotate when the housing 1 moves. The rotation of the roller 3 can drive the friction wheel 6 to rotate in place. Since the friction wheel 6 contacts the top of the friction area 101, and the top of the friction area 101 has a large friction, the friction wheel 6 rotates in place. The friction wheel 6 is prevented from rotating due to the friction, while the roller 3 drives it to rotate in place. Therefore, the rotation of the friction wheel 6 in place will be transformed into movement along the friction zone 101, causing the friction wheel 6 to move to the right and reset. During the reset process, the first pull rope 7 will pull the sealing plate 5 to move. After the friction wheel 6 is reset, it will be located on the right side of the friction zone 101. Since the top right side of the friction zone 101 does not have friction properties, the friction wheel 6 will no longer move after reset and will only be affected by the rotation of the roller 3, causing it to rotate in place. The friction wheel 6 is connected to the first pull rope 7 via a rotating ring, which is essentially a rotatable connection. Therefore, the rotation of the friction wheel 6 will not cause any impact. After the friction wheel 6 resets, the sealing plate 5 no longer seals the discharge port of the housing 1. At this time, the discharge port of the housing 1 is no longer located above the rectangular hole. Thus, the problem of the discharge mortar being sprayed into the rectangular hole if the discharge port is opened at this time is avoided after the brake shaft 4 resets, when the discharge port of the housing 1 is still above the rectangular hole. It is worth noting that the brake shaft 4 resets, and the discharge mortar is still located above the rectangular hole. When the moving shaft 4 is driven into the rectangular hole again, the second spring will be released, causing the push rod 8 and the push body 9 to move away from the friction wheel 6. During the process of the sealing plate 5 pulling the friction wheel 6, its power source is the first spring, and the force of the first spring is greater than the friction at the top of the friction area 101, thus enabling the sealing plate 5 to smoothly pull the friction wheel 6 to move. At the same time, during the process of the sealing plate 5 pulling the friction wheel 6, the friction wheel 6 will contact and rotate with the roller 3. Since the friction wheel 6 is connected to the first pull rope 7 through the rotating ring, the rotation of the friction wheel 6 will not cause any impact.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
