Description

Technical Field

[0001] The utility model relates to the technical field of glass scrapers, in particular to a safety glass scraper. Background Art

[0002] A glass scraper is a cleaning tool used on glass surfaces. The blade can be used to remove stains on the glass surface. When decorating a house, there is often dripping solidified mud or glue on the glass or the ground, which can be easily scraped off with a blade.

[0003] During use, the blade is usually placed in a housing and extended and retracted by hand. If the blade does not have an automatic retraction structure, it is easy to forget to store the blade in the housing, and the extended blade poses a safety risk. In particular, when the scraper needs to be put into a pocket, the risk factor is even higher. Therefore, it is necessary to design a glass scraper that can automatically retract while ensuring the stability of the blade after it is extended. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-4As shown, the safety glass scraper proposed by the utility model comprises an outer shell 1 and a blade body 3, an inner cavity 13 is provided in the outer shell 1, a blade clamp 2 is slidably connected in the inner cavity 13, the blade clamp 2 is a U-shaped structure, and the open end extends out of the outer shell 1, a fixed cavity 21 is provided at the open end of the blade clamp 2, a blade seat 31 with the same size as the fixed cavity 21 is fixed at the end of the blade body 3, a sliding groove 11 is provided at the upper end of the inner cavity 13, a push block 4 is fixed at the upper end of the blade clamp 2 and at a position corresponding to the sliding groove 11, a positioning component 6 is provided between the push block 4 and the bottom of the inner cavity 13, a reset spring 53 is installed between the inner side of the inner cavity 13 and the blade clamp 2, an anti-skid pad 14 is fixed to the side wall of the opening of the inner cavity 13, the inner side of the anti-skid pad 14 is against the outer wall of the blade clamp 2, the blade clamp 2 is made of elastic metal material, and a through hole 12 is provided in the middle position of the rear side of the outer shell 1.

[0020] A sliding plate 52 is slidably connected inside the inner cavity 13 and located at the rear side of the blade clamp 2. A pair of connecting blocks 51 are fixed on the front side of the sliding plate 52. An insertion rod 5 is fixed inside the blade clamp 2. Both ends of the insertion rod 5 are fixed to the connecting blocks 51. A return spring 53 is fixed between the sliding plate 52 and the inner wall of the inner cavity 13.

[0021] The positioning assembly 6 includes an end plate 62 and a positioning hole 65. A telescopic groove 61 is provided at the upper end of the push block 4. The end plate 62 is slidably connected in the telescopic groove 61, and the upper end extends out of the telescopic groove 61. A vertical rod 63 is fixed to the bottom of the end plate 62. The positioning hole 65 is provided at the bottom of the inner cavity 13 and is aligned with the vertical rod 63. The bottom of the vertical rod 63 passes through the blade clamp 2 and is inserted into the positioning hole 65. An ejection spring 64 is fixed between the bottom of the telescopic groove 61 and the end plate 62. An adapter hole 22 is provided on the blade clamp 2 and is aligned with the vertical rod 63. The vertical rod 63 passes through the adapter hole 22.

[0022] In this embodiment, the blade clamp 2 can slide inside the inner cavity 13 by pushing the push block 4. When sliding forward, the blade body 3 can be extended from the inner cavity 13, and the reset spring 53 can be stretched. After releasing the push block 4, the reset spring 53 is used to reset the sliding plate 52, and finally the blade clamp 2 and the blade body 3 are driven into the belt housing 1 to achieve the purpose of automatic retraction. In order to ensure that the blade body 3 is stably extended during operation, after the blade body 3 is extended, the position of the vertical rod 63 will be aligned with the positioning hole 65. At this time, the end plate 62 can be pressed down by fingers to compress it. When the spring 64 is ejected, the end plate 62 and the vertical rod 63 are driven to move downward, and finally the bottom of the vertical rod 63 is inserted into the positioning hole 65, ensuring that the blade body 3 is stably extended. At the same time, the blade body 3 can be retracted as long as the hand is released, ensuring the storage safety. When replacing the blade body 3, it is necessary to continuously push the protrusion forward so that the blade clamp 2 can extend further out of the shell 1. At this time, after the openings on both sides of the fixed cavity 21 extend out of the shell 1, the blade body 3 can be pulled out from both sides, and the disassembly and assembly operation can be easily completed. On the contrary, when in use, the blade seat 31 is located inside the shell 1 to ensure the stability of the blade body 3.
