Description

Technical Field

[0001] This utility model relates to the field of scraper technology, specifically a combination scraper for decoration. Background Technology

[0002] During the renovation and decoration process, there are often multiple scraping and cleaning operations involved, such as removing old wallpaper, cleaning adhesive residue from tile grout, repairing wall putty, and removing silicone sealant. As a core tool, the ease of use, safety, and adaptability of the scraper directly affect the construction efficiency and quality.

[0003] For example, patent number CN221211750U discloses a shovel, including a handle, a first shovel fixing head, a second shovel fixing head, and a blade. The first shovel fixing head is disposed at the front end of the handle, and the first shovel fixing head and the handle are integrally formed. A mounting groove is provided on one side of the first shovel fixing head, and the second shovel fixing head is disposed in the mounting groove. A through hole is provided on the first shovel fixing head, and a fixing post with an internal thread structure is provided on the second shovel fixing head at a position corresponding to the through hole. A threaded rod is provided on the outer side of the first shovel fixing head.

[0004] While the aforementioned device can solve the above technical problems, the blade of the fixed shovel is exposed without any storage or protective structure. During idle storage, on-site handling, or high-altitude operations, the sharp edge can easily cut construction workers. At the same time, the exposed edge is also prone to dust and moisture accumulation, and after long-term storage, it is prone to rust and dulling, which greatly shortens the service life of the shovel blade. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a combined scraper for decoration, which solves the problem of exposed scraper blades without any storage or protective structure.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A modular scraper for decoration includes: a handle, an anti-slip sleeve fixedly connected to the outer wall of the handle base plate, and a scraper head structure fixedly connected to the inner wall of the top of the handle; the scraper head structure includes a protective plate, a connecting plate slidably connected to the inner wall of the protective plate, a scraper blade slidably connected to the inner wall of the connecting plate, a push handle fixedly connected to the outer wall of the connecting plate, a screw threadedly connected to the inner wall of the connecting plate, and sliders symmetrically fixedly connected to the outer wall of the side of the connecting plate, with slots formed on the outer wall of the side of the sliders.

[0010] Preferably, the outer wall of the screw is slidably connected to the inner wall of the blade, and the outer wall of the slider is slidably connected to the inner wall of the side of the protective plate. When it is necessary to replace blades of different specifications to adapt to different working scenarios, first loosen the screws on the inner wall of the connecting plate to release the screws from squeezing and fixing the blades, take the old blades out of the mounting slot of the connecting plate, and then put the new blades of the new specifications into the corresponding mounting position of the connecting plate. After aligning the connecting holes of the screws, tighten the screws. The screw threads lock the blades firmly on the connecting plate, thus completing the quick replacement of the blades.

[0011] Preferably, a sliding rod is fixedly connected to the inner wall of the side of the protective plate, and a tension spring is fixedly connected to the inner wall of the bottom of the protective plate.

[0012] Preferably, the tension spring is disposed outside the slide rod, the outer wall of the slide rod is slidably connected to the inner wall of the slider, and the outer wall of the tension spring on the side away from the protective plate is fixedly connected to the outer wall of the bottom of the slider. In the initial state, the connecting plate and the scraper blade are stored inside the protective plate, the tension spring is in a naturally contracted state, and the slider is in the initial position of adhering to the inner wall of the protective plate.

[0013] Preferably, the inner wall of the side of the protective plate is symmetrically provided with sliding grooves, and the inner wall of the sliding groove is slidably connected with a locking block. The outer wall of the locking block is fixedly connected with a pull rod, the outer wall of the pull rod is fixedly connected with a pull handle, and the outer wall of the locking block is fixedly connected with a compression spring.

[0014] Preferably, the outer wall of the compression spring on the side away from the locking block is fixedly connected to the inner wall of the slide groove, the outer wall of the pull handle is slidably connected to the inner wall of the slide groove, and the outer wall of the locking block is slidably connected to the inner wall of the locking groove. Pulling the pull handles on both sides causes the locking block to disengage from the locking groove through the pull rod, releasing the limitation on the slider. At this time, the rebound force of the tension spring will pull the slider to slide down along the slide rod, and the connecting plate will drive the shovel blade to retract synchronously into the protective plate, realizing the storage and protection of the shovel blade.

[0015] (III) Beneficial Effects

[0016] This utility model provides a combined scraper for decoration and renovation. It has the following beneficial effects:

[0017] (I) The shovel head structure is equipped with a protective plate and a telescopic storage structure. In the initial state, the shovel blade can be completely stored inside the protective plate. After the operation is completed, it can also be automatically reset and stored by the rebound force of the tension spring. The protective plate can effectively isolate the blade edge of the shovel, preventing the blade edge from scratching the operator during idle or transportation. At the same time, it can prevent the blade edge from getting contaminated with dust and moisture and rusting, thus extending the service life of the shovel blade.

[0018] (ii) The connecting plate is fixed by screws through a detachable structure for the scraper blades. Different specifications of scraper blades, such as flat, pointed, and curved blades, can be quickly replaced according to different decoration conditions. It is suitable for various work needs such as removing old wallpaper from walls, cleaning adhesive stains in tile gaps, and scraping putty from curved pipes. There is no need to equip multiple special scrapers, which reduces the number of construction tools to carry and lowers construction costs. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6This utility model provides a technical solution: a combined scraper for decoration, comprising: a handle 2, an anti-slip sleeve 3 fixedly connected to the outer wall of the bottom plate of the handle 2, and a scraper head structure 1 fixedly connected to the inner wall of the top of the handle 2; the scraper head structure 1 includes a protective plate 11, a connecting plate 12 slidably connected to the inner wall of the protective plate 11, a scraper blade 13 slidably connected to the inner wall of the connecting plate 12, a push handle 14 fixedly connected to the outer wall of the connecting plate 12, a screw 15 threadedly connected to the inner wall of the connecting plate 12, and sliders 16 symmetrically fixedly connected to the outer wall of the side of the connecting plate 12, with slots 17 formed on the outer wall of the side of the slider 16.

[0028] The outer wall of screw 15 is slidably connected to the inner wall of blade 13, and the outer wall of slider 16 is slidably connected to the inner wall of side of protective plate 11. When it is necessary to replace blades 13 of different specifications to adapt to different working scenarios, first loosen screw 15 on inner wall of connecting plate 12 to release the screw 15 from squeezing and fixing blade 13, take the old blade 13 out of the mounting slot of connecting plate 12, and then put the new blade 13 into the corresponding mounting position of connecting plate 12. After aligning with the connecting hole of screw 15, tighten screw 15. The screw 15 is firmly fixed to connecting plate 12 by the thread locking force of screw 15, thus completing the quick replacement of blade 13.

[0029] A sliding rod 18 is fixedly connected to the inner wall of the side of the protective plate 11, and a tension spring 19 is fixedly connected to the inner wall of the bottom of the protective plate 11.

[0030] The tension spring 19 is disposed outside the slide bar 18. The outer wall of the slide bar 18 is slidably connected to the inner wall of the slider 16. The outer wall of the tension spring 19 on the side away from the protective plate 11 is fixedly connected to the outer wall of the bottom of the slider 16. In the initial state, the connecting plate 12 and the scraper blade 13 are stored inside the protective plate 11, the tension spring 19 is in a naturally contracted state, and the slider 16 is in the initial position of adhering to the inner wall of the protective plate 11.

[0031] The inner wall of the protective plate 11 is symmetrically provided with sliding grooves 191, and a locking block 192 is slidably connected to the inner wall of the sliding groove 191. A pull rod 193 is fixedly connected to the outer wall of the locking block 192, a pull handle 194 is fixedly connected to the outer wall of the pull rod 193, and a compression spring 195 is fixedly connected to the outer wall of the locking block 192.

[0032] The outer wall of the compression spring 195 away from the block 192 is fixedly connected to the inner wall of the slide groove 191. The outer wall of the handle 194 is slidably connected to the inner wall of the slide groove 191. The outer wall of the block 192 is slidably connected to the inner wall of the slot 17. Pulling the handles 194 on both sides causes the block 192 to disengage from the slot 17 via the pull rod 193, releasing the limit on the slider 16. At this time, the rebound force of the tension spring 19 will pull the slider 16 to slide down along the slide rod 18. The connecting plate 12 drives the scraper blade 13 to retract into the protective plate 11 simultaneously, realizing the storage and protection of the scraper blade 13.

[0033] When in use, the safety, convenience and adaptability of shoveling operations are achieved through the telescopic adjustment of the shovel head structure 1, the detachable fixing of the shovel blade 13 and the limiting lock of the slider 16 slot 17. The operator operates by holding the anti-slip sleeve 3 on the handle 2.

[0034] In the initial state, the connecting plate 12 and the blade 13 are housed inside the protective plate 11, the tension spring 19 is in a naturally contracted state, and the slider 16 is in the initial position against the inner wall of the protective plate 11. When a scraping operation is required, the operator first pushes the handle 14 upward, and the connecting plate 12 drives the slider 16 to slide upward along the slide bar 18 on the inner wall of the protective plate 11. The tension spring 19 is gradually stretched and accumulates elastic force as the slider 16 moves. At the same time, the slider 16 will squeeze the locking block 192 to slide outward along the slide groove 191, and the compression spring 195 is compressed. When the blade 13 extends to the required working length, the rebound force of the compression spring 195 pushes the locking block 192 to reset and re-lock into the corresponding slot 17, completing the position locking of the scraper head structure 1, and the scraping operation for decoration can then be carried out.

[0035] When it is necessary to replace the scraper blade 13 with a different specification to adapt to different working scenarios, first loosen the screw 15 on the inner wall of the connecting plate 12 to release the screw 15 from squeezing and fixing the scraper blade 13. Take the old scraper blade 13 out of the mounting slot of the connecting plate 12, and then put the new scraper blade 13 into the corresponding mounting position of the connecting plate 12. After aligning with the connecting hole of the screw 15, tighten the screw 15. The screw 15 will be firmly fixed to the connecting plate 12 by the thread locking force of the screw 15, thus completing the quick replacement of the scraper blade 13 and meeting the scraping needs of different decoration working conditions.

[0036] After the operation is completed, pull the two handles 194 again to disengage the locking block 192 from the slot 17 via the pull rod 193, thereby releasing the limit on the slider 16. At this time, the rebound force of the tension spring 19 will pull the slider 16 to slide down along the slide rod 18. The connecting plate 12 will drive the shovel blade 13 to retract into the protective plate 11 in sync, thus realizing the storage and protection of the shovel blade 13. After releasing the handle 194, the locking block 192 will reset, and the shovel head structure 1 will return to the storage state. The protective plate 11 can effectively prevent the blade edge of the shovel blade 13 from cutting personnel.
