Description

Technical Field

[0001] The utility model relates to a brush, in particular to a crevice brush. Background Art

[0002] It is inconvenient to clean the gaps, so a gap brush was invented, such as the storage-type furniture gap dust removal brush disclosed in CN104643563A, which includes a brush handle and at least one row of brushes connected to the front end of the brush handle, a groove is provided on the inner side of the brush handle, and a scraper is connected to the rear end of the brush handle, which is embedded in the groove. The head of the scraper has an arc-shaped scraping head that is integral with the scraper, and an arc-shaped scraping groove is provided on the outer side of the scraping head. The storage-type furniture gap dust removal brush adopts a brush of this design, and can use the arc-shaped scraping head to remove some accumulated dust and stubborn dirt, thereby achieving the purpose of thorough cleaning. However, the brush head part in the patent cannot be removed, so it cannot be replaced. At the same time, the structure with an extension rod cannot be well controlled when cleaning the desktop, which is very inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is now further described with reference to the accompanying drawings.

[0027] like Figure 1-7 As shown, a crevice brush comprises a brush body 1, a mounting handle 2 and a hinged spring buckle 3, one end of the mounting handle 2 is provided with a spring buckle mounting groove 21, the hinged spring buckle 3 is embedded in the spring buckle mounting groove 21, the mounting handle 2 is connected to the brush body 1 through the hinged spring buckle 3, two elastic arms 31 are provided on the hinged spring buckle 3, a space for the two elastic arms 31 to move is provided in the spring buckle mounting groove 21, hinged columns 32 are provided on the outer side walls of the two elastic arms 31, a hinged groove 11 is provided on the brush body 1, the lower end of the mounting handle 2 is inserted into the hinged groove 11, and a hinged hole 12 is provided on the side wall of the hinged groove 11 on the brush body 1, the elastic arms 31 on both sides are unfolded outward to push the hinged columns 32 on both sides to be hinged into the hinged holes 12, and the brush body 1 and the mounting handle 2 are connected by the hinged columns 32 and the hinged holes 12.

[0028] Optionally, an extension rod may be provided on the side of the mounting handle 2 away from the brush body 1 , and the extension rod may be threadedly connected or clamped to the mounting handle 2 , thereby achieving a long-distance cleaning effect.

[0029] like Figure 5-7 As shown, it is optional that in the present embodiment, a plurality of elastic arms 31 may be provided on the hinged spring buckle 3, and the number of the elastic arms 31 may be 1-5, wherein 2 are preferably provided, so that the user can separate the brush body 1 and the mounting handle 2 by pressing two elastic arms 31 simultaneously with one hand.

[0030] In this solution, the axis lines of the hinged columns 32 on the two brush bodies 1 are on the same straight line, so that the brush body 1 can rotate at a certain angle with the axis of the hinged column 32 as the circular axis, so as to improve the cleaning efficiency and flexibility of the crevice brush.

[0031] Preferably, a docking notch 22 is provided at a position below the mounting handle 2, and a docking protrusion 33 that fits with the docking notch 22 is provided on the articulated snap 3. By the mutual cooperation of the provided docking notch 22 and the docking protrusion 33, the articulated snap 3 can be stably docked and installed with the mounting handle 2, preventing the articulated spring piece from falling off the mounting handle 2.

[0032] Preferably, a fitting member 35 is provided on the inner arm of the articulated snap 3, and the fitting member 35 is embedded in the snap mounting groove 21. Through the cooperation of the provided fitting member 35 and the snap mounting groove 21, the setting stability of the articulated snap 3 in the mounting handle 2 is ensured, preventing the articulated snap 3 from axially rotating on the mounting handle 2.

[0033] As Figure 5-6 shown, the articulated snap 3 in this solution is arranged in a V shape, or a U shape, or a U-shaped setting. The outer side wall of the articulated snap 3 fits with the outer side wall of the mounting handle 2. Among them, it is preferably to set the articulated snap 3 in a V shape. The mounting handle 2 is arranged in an inverted conical shape, and the cross-section of the articulated groove 11 is arranged in an inverted triangle shape, so as to further improve the movement range of the mounting handle 2 in the articulated groove 11 and improve the cleaning flexibility of the gap brush.

[0034] On this basis, in order to further improve the pressing convenience of the elastic members on both sides, pressing protrusions 34 are respectively provided on the outer side surfaces of the elastic arms 31, and the pressing protrusions 34 are arranged above the articulated columns 32. The staff can press the pressing protrusions 34 to bend the elastic arms 31 on both sides inward, so that the articulated columns 32 are separated from the articulated holes 12. At this time, the brush body 1 and the mounting handle 2 can be separated.

[0035] Preferably, a connecting portion 23 is provided inside the snap mounting groove 21, and the connecting portion 23 is对接 with the inside of the mounting handle 2. The two elastic arms 31 are arranged on both sides of the connecting portion 23, so as to further improve the structural strength of the mounting handle 2.

[0036] Preferably, a hypotenuse is provided on the lower side of the articulated column 32. During use, the mounting handle 2 can be directly pressed down onto the articulated groove 11 on the brush body 1. The hypotenuse on the articulated column 32 abuts against the inner arm of the articulated groove 11 to bend the elastic arms 31 on both sides inward and slide into the articulated holes 12 to achieve rapid installation.

[0037] The technical principle of the present invention has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted in any way as a limitation of the protection scope of the present invention. Based on the explanations herein, those skilled in the art can联想到 other specific embodiments of the present invention without creative labor, and these embodiments will fall within the protection scope of the claims of the present invention.
