Description

Technical Field

[0001] The present application relates to the technical field of film scrapers, and in particular to a wall film scraper. Background Art

[0002] Wallpaper, also known as wall paper, is an interior decoration material used for wall coverings. It is widely used in interior decoration of residences, offices, guesthouses, and hotels. The material is not limited to paper, but also includes other materials. Wallpaper is divided into many categories, such as laminated wallpaper, coated wallpaper, embossed wallpaper, etc. The base paper is usually produced from bleached chemical wood pulp, and then processed through different processes, such as coating, printing, embossing or surface coating, and finally cut and packaged before leaving the factory. It has certain strength, toughness, beautiful appearance and good water resistance. When laying wallpaper, a scraper is generally used to scrape the wallpaper flat.

[0003] The existing patent (publication number: CN207711689U) discloses a new wallpaper scraper. The handle is connected to the upper part of the scraper body. The upper part of the scraper body is provided with a trapezoidal recess. The handle is set in the middle position of the trapezoidal recess. The handle and the upper part of the scraper body are on the same horizontal plane. The handle is provided with an anti-slip sleeve. A sharp corner is provided on one side of the scraper body. A scale is provided at the lower part of the scraper body. A rectangular recess is provided on the scraper body above the scale. The scraper body below the scale is also fixedly connected to a scraper strip, providing a simple structure and easy use. It can not only effectively promote the fit of wallpaper, but also clean dust attached to the surface of wallpaper.

[0004] However, during use, the above patent requires workers to stand on a ladder to complete the film application work when scraping the film at a high place. When film application work needs to be performed at different locations, the workers need to come down, move the ladder to the area where the film needs to be applied, and then climb up the ladder to work. The time spent in moving the ladder is too long, resulting in low work efficiency. At the same time, standing on the ladder to work may cause accidents, resulting in injuries to the workers. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a wall film scraper with advantages such as ease of use. However, the above patent requires workers to stand on a ladder to complete the film work when scraping the film at a high place during use. When film work needs to be performed at different locations, the workers need to come down, move the ladder to the area where the film needs to be pasted, and then climb up the ladder to work. The time spent in moving the ladder is too long, resulting in low work efficiency. At the same time, standing on the ladder to work may cause accidents, resulting in injuries to the workers.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a wall film scraper, comprising a support rod, a telescopic rod being slidably connected to the inside of the support rod, a plurality of positioning holes being provided on the surface of the support rod, the positioning holes being provided along the length direction of the support rod, a fixing groove being provided at the lower end of the telescopic rod, a second spring being fixedly connected to the inside of the fixing groove, one end of the second spring being fixedly connected to a telescopic block corresponding to the plurality of positioning holes, one end of the telescopic block passing through the fixing groove and extending to the surface of the telescopic rod.

[0007] Through the above solution, a second spring is fixedly connected inside the telescopic rod, and one end of the second spring is fixedly connected to a telescopic block corresponding to the positioning hole. When it is necessary to apply film to a high place during use, it is only necessary to press the telescopic block with your hand. Since the telescopic block is connected to the second spring, the telescopic block will move into the telescopic rod when pressed. Then, the telescopic rod is pulled to adjust the length of the part of the telescopic rod that protrudes from the support rod until the telescopic block protrudes from the positioning hole.

[0008] Furthermore, the lower end of the telescopic rod is fixedly connected to a rotating seat, and a rotating block is rotatably connected inside the rotating seat.

[0009] Through the above solution, the rotating block can rotate inside the rotating seat during actual use.

[0010] Furthermore, the lower end of the rotating block is fixedly connected to a mounting seat, a slide rail is provided inside the mounting seat, a mounting groove is provided inside the slide rail, a rotating frame is rotatably connected inside the mounting groove, and a clamping block is fixedly connected to the lower end of the rotating frame.

[0011] With the above solution, when the rotating frame rotates clockwise, it drives the clamping block to move downward.

[0012] Furthermore, a first spring is fixedly connected to the upper end of the interior of the installation slot, and the lower end of the first spring is fixedly connected to the upper end of the rotating frame on one side close to the clamping block.

[0013] Through the above solution, when the end of the rotating frame away from the clamping block is not subjected to force, the first spring will drive the clamping block to move downward.

[0014] Furthermore, a sliding block is slidably connected inside the slide rail.

[0015] Through the above solution, the sliding block is slidably connected to the slide rail so that the sliding block can slide out from any end of the slide rail.

[0016] Furthermore, a scraper is fixedly connected to the lower end of the sliding block, and a clamping groove corresponding to the clamping block is opened on the surface of the sliding block.

[0017] Through the above solution, when the locking block is located in the locking slot, the sliding block will be locked, and at this time the sliding block will not move inside the slide rail.

[0018] Furthermore, a button is fixedly connected to one side end of the rotating frame away from the clamping block, and the button passes through the slide rail and extends to the upper end of the slide rail.

[0019] According to the above solution, when the button is pressed, the button will move downward under the action of pressure, and the button will drive the rotating frame to rotate.

[0020] Furthermore, the upper end of the support rod is fixedly connected to a handle, and the upper end of the handle is fixedly connected to a limit plate.

[0021] With the above solution, the staff needs to hold the handle to perform the film application during use.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The wall film scraper is fixedly connected to a second spring inside the telescopic rod, and one end of the second spring is fixedly connected to a telescopic block corresponding to the positioning hole. When in use, when it is necessary to apply film to a high place, it is only necessary to press the telescopic block by hand. Because the telescopic block is connected to the second spring, the telescopic block will move into the telescopic rod when pressed, and then the telescopic rod is pulled to adjust the length of the part of the telescopic rod that protrudes from the support rod until the telescopic block protrudes from the positioning hole. During use, there is no need for workers to climb up the ladder to perform the film application operation, the operation process is safer, and the time of moving the ladder can be saved, and the efficiency is relatively high. At the same time, when scrapers of different specifications need to be replaced for work in different areas, it is only necessary to press the button to make the button move downward, which will drive the rotating frame to rotate. The rotation of the rotating frame will drive the block at the end of the rotating frame away from the button to move upward. When the block leaves the slot, the scraper can be taken out and replaced with scrapers of different sizes. The scope of application is relatively wide. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, the staff needs to hold the handle 6 to perform the film application work, a plurality of positioning holes 3 are opened on the surface of the support rod 1, and the positioning holes 3 are opened along the length direction of the support rod 1, and a fixing groove 18 is opened at the lower end of the telescopic rod 2, and a second spring 19 is fixedly connected inside the fixing groove 18. One end of the second spring 19 is fixedly connected to a telescopic block 20 corresponding to the plurality of positioning holes 3, and one end of the telescopic block 20 passes through the fixing groove 18 and extends to the surface of the telescopic rod 2.

[0033] See also Figure 1 、 Figure 2 The lower end of the telescopic rod 2 is fixedly connected to a rotating seat 5, and the rotating block 7 is rotatably connected inside the rotating seat 5. During actual use, the rotating block 7 can rotate inside the rotating seat 5. The lower end of the rotating block 7 is fixedly connected to a mounting seat 8. A slide rail 9 is provided inside the mounting seat 8. A sliding block 10 is slidably connected inside the slide rail 9. The sliding block 10 is slidably connected to the slide rail 9, so the sliding block 10 can slide out from either end of the slide rail 9. The lower end of the sliding block 10 is fixedly connected to a scraper 11.

[0034] See also Figure 3When the cam 13 is in the state of being moved, the spring 16 is pressed against the top of the cam 13 and the spring 16 is pressed against the top of the cam 13 so that the cam 13 can be moved downwards.

[0035] In this embodiment, when scrapers 11 of different specifications need to be replaced for working in different areas, it is only necessary to press the button 14 to move the button 14 downward, which will then drive the rotating frame 13 to rotate. The rotation of the rotating frame 13 will drive the block 15 at one end of the rotating frame 13 away from the button 14 to move upward. When the block 15 leaves the slot 17, the scraper 11 can be taken out and replaced with scrapers 11 of different sizes. The scope of application is relatively wide.

[0037] The working principle of the above embodiment is:

[0038] When in use, the staff only needs to hold the handle 6 to carry out the film pasting work. When it is necessary to apply the film to a high place, it is only necessary to press the telescopic block 20 with the hand. Because the telescopic block 20 is connected to the second spring 19, the telescopic block 20 will move into the telescopic rod 2 when pressed again, and then the telescopic rod 2 is pulled to adjust the length of the part of the telescopic rod 2 that leaks out of the support rod 1 until the telescopic block 20 leaks out of the positioning hole 3. During use, there is no need for the staff to climb the ladder to perform the film pasting operation. The operation process is safer and can save time in moving the ladder. The efficiency is relatively high. At the same time, when it is necessary to replace scrapers 11 of different specifications for work in different areas, it is only necessary to press the button 14 to make the button 14 move downward, and then the rotating frame 13 will rotate. The rotation of the rotating frame 13 will drive the block 15 at one end of the rotating frame 13 away from the button 14 to move upward. When the block 15 leaves the slot 17, the scraper 11 can be taken out and replaced with scrapers 11 of different sizes.
