[0002] In the field of interior decoration, in order to save indoor space and improve aesthetics, water pipes and electrical wires are all designed to be hidden. That is, during the water and electricity renovation process, cable troughs or pipe troughs are dug on the walls and the ground in advance. After the wire pipes are buried, cement mortar needs to be filled in the cable troughs and the cable troughs need to be filled and powdered to ensure the stability of the cable troughs and the flatness of subsequent construction (this process is collectively referred to as powdering the troughs).

[0003] The existing powder trough process is that the operator pours the mixed cement mortar into the line trough, and then scrapes back and forth with a handheld scraper to fill the cement mortar into the line trough to complete the powder trough.

[0004] The existing powder trough process has the following defects: when the operator is powdering the trough, excess cement mortar will fall to the ground, resulting in a waste of material costs and inconvenience in subsequent floor cleaning; at the same time, when powdering the trough, the cement mortar cannot be completely filled in the line trough, which is prone to material shortages and voids, and is prone to cracking during subsequent painting construction, affecting the aesthetics. Utility Model Content

[0005] The utility model provides a special scraper for a powder trough with adjustable width, which solves the defects of the existing powder trough process, such as material waste and the inability of cement mortar to completely fill the line trough, which easily causes material shortage and cracking.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: the present invention provides a special scraper for a powder trough with adjustable width, which comprises:

[0030] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1-3The figure is a schematic diagram of the structure of the utility model of the width-adjustable powder trough scraper, which includes a main board 1, an adjustment component, a scraper 17, a scraping trough and a scraping portion 19. The main board 1 is a rectangular plate having a first back side and a second back side (the first back side and the second back side are arranged oppositely, as shown in FIG. Figure 1 As shown, the first back side and the second back side are the two sides of the rectangular plate with the largest area, that is, the sides surrounded by the long side and the wide side).

[0034] There are two groups of guide components, which are relatively arranged on the first back side of the main board 1. The two groups of guide components can be adjusted inward or outward synchronously, thereby adjusting the width spacing between the two groups of guide components to meet the mortar scraping operations of wire troughs of different widths and improve versatility.

[0035] The guide assembly includes a side baffle 7, a guide plate 8, a positioning hole 9 and a positioning column 10. The side baffle 7 is arranged on the first back side of the main board 1 and is parallel to the long side of the main board 1. The guide plate 8 is integrally connected to one side of the side baffle 7 and is tilted inward. When scraping cement mortar, the inclined guide plate 8 can gather the cement mortar on both sides of the wire groove inward, thereby improving the fullness of the mortar coating and avoiding the hollowing phenomenon, which leads to subsequent cracking; and the inclined guide plate 8 gathers the cement mortar inward, making it convenient for the material trough 18 at the bottom of the main board 1 to collect excess cement mortar, avoiding the cement mortar from overflowing outward during the powder trough process, thereby causing waste of cement mortar, and also avoiding the situation where the overflowed material is not cleaned in time after falling to the ground, making it difficult to clean after hardening.

[0036] Positioning holes 9 are spaced apart on the main plate 1. Positioning posts 10 are inserted into these holes with an interference fit and rest against the outside of the guide plate 8. During the powder troughing process, the guide plate 8 scrapes the cement mortar around the wire trough inward. Because cement mortar has a certain viscosity, the guide plate 8 is easily deformed by the force applied during scraping. Therefore, the positioning posts 10 rest against the outside of the guide plate 8 to enhance the structural strength of the guide plate 8 during the scraping process. After adjusting the position of the side baffles 7 and guide plate 8, the positioning posts 10 can be removed and reinserted into the appropriate positioning holes 9.

[0037] The positioning column 10 abuts against the center point of the guide plate 8 to ensure that the guide plate 8 is subjected to more uniform force when scraping cement mortar.

[0038] The limiting plate 2 is fixed to the first back side of the main plate 1. The limiting slot 3 extends horizontally through the limiting plate 2. The adjusting plate 6 is fixed to the inner side of the side baffle 7 and inserted into the limiting slot 3. The adjusting plate 6 can move within the limiting slot 3, thereby driving the side baffle 7 and the guide plate 8 to move, thereby changing the width of the gap between the two sets of guide assemblies, meeting the mortar scraping operation of different widths of cable trunking and improving versatility.

[0039] The width of the adjusting plate 6 is equal to the width of the limiting groove 3, and the thickness of the adjusting plate 6 is equal to the thickness of the limiting groove 3. When the adjusting plate 6 moves, the limiting groove 3 will limit the adjusting plate 6 to prevent the adjusting plate 6 from shaking during the movement, thereby affecting the scraping effect of the powder trough.

[0040] The gear 4 is rotatably mounted in the limiting groove 3, and the rack 5 is fixed on the inner side of the adjustment plate 6 and meshes with the gear 4. The gear 4 is rotated to drive the rack 5 to move, thereby driving the adjustment plate 6 to move in the limiting groove 3. Figure 3 As shown, when the gear 4 rotates, it will drive the upper and lower racks 5 to move inward or outward synchronously, and then drive the guide components on both sides to move inward or outward synchronously. When scraping cement mortar, it ensures that the cement mortar is gathered more evenly in the groove, avoiding the defect of inconsistent mortar distribution on the left and right sides.

[0041] Rotating column 14 is connected to gear 4 and extends through main plate 1. Knob 15 is fixed to the end of rotating column 14 away from gear 4. Knob 15 facilitates the oiler's rotation of gear 4, thereby adjusting the diversion components on both sides. Handle 16 is fixed to the second back side of main plate 1. The operator holds handle 16 to scrape cement mortar into the cable duct.

[0042] like Figure 4 As shown, a through slot 11 extends through the adjustment plate 6. Internal fixing holes 12 are spaced apart in the through slot 11, and the diameter of the internal fixing holes 12 is greater than the width of the through slot 11. An external fixing hole 13 extends through the main plate 1 and the limit plate 2 and mates with the internal fixing hole 12. The operator turns the knob 15 to rotate the gear 4. Due to the meshing of the gear 4 with the rack 5, the adjustment plate 6 and the diverter components on both sides move. When the adjustment plate 6 is moved to the appropriate position, a fastening bolt is inserted through the external fixing hole 13 and the internal fixing hole 12, and a fastening nut is added on the other side to secure the position of the adjustment plate 6 (the fastening bolt mates with the internal fixing hole 12 and the external fixing hole 13, so the diameter of the fastening bolt is greater than the diameter of the through slot 11).

[0043] Since the diameter of the fastening bolt is larger than the diameter of the through slot 11 , the fastening bolt will be stuck in the through slot 11 , thereby preventing the gear 4 from loosening and causing the position of the adjustment plate 6 to shift when scraping the cement mortar.

[0044] The scraper 17 is integrally connected to the bottom of the main board 1, and the material trough 18 is arranged on the side of the scraper 17 facing the guide component. The guide component gathers the cement mortar on both sides of the wire trough inward, and the excess cement mortar will fall into the material trough 18, avoiding the waste of cement mortar and also saving the subsequent cleaning process.

[0045] The scraping portion 19 is arranged on the side of the scraper 17 away from the main board 1, and the cross-section of the scraping portion 19 is pointed. The scraping portion 19 is used to perform secondary scraping treatment on the cement mortar gathered in the wire groove to improve the fullness of the cement mortar filling. At the same time, the excess cement mortar on both sides of the wire groove can be scraped flat to improve the effect after the powder groove is powdered.

[0046] When the utility model uses a special scraper for powder trough with adjustable width, the operator first adjusts the distance between the two groups of guide components, and the operator holds the handle 16 and scrapes it from top to bottom. The guide plate 8 gathers the cement mortar on both sides of the line trough inward, thereby improving the fullness of the mortar smear and avoiding the hollowing phenomenon. The excess cement mortar falls into the material trough 18 below (initial scraping); then scrape it from bottom to top, and the scraper 17 performs a secondary scraping treatment on the cement mortar gathered in the line trough. At the same time, the excess cement mortar on both sides of the line trough can be scraped flat, thereby improving the effect of the powder trough (fine scraping).

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
