Abstract
Description
Technical Field
[0001] This utility model relates to handheld products. Background Technology
[0002] Handheld products, such as handheld cleaners, handheld power tools, and handheld appliances, are equipped with handles for users to hold. For ease of storage and transportation, the handles can be designed to be foldable. Foldable handles can rotate around a pivot point to close to the product body, thus achieving the folding function. Utility Model Content
[0003] The technical problem solved by this utility model is that the handle can be positioned when rotated to a predetermined position.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a folding handle structure, including a handle connecting part of the main body of the product and a folding handle hinged to the handle connecting part. The handle connecting part is provided with an arc-shaped limiting track, and the folding handle is provided with a limiting block that cooperates with the arc-shaped limiting track. The end of the arc-shaped limiting track is provided with a positioning groove, and a telescopic spring is provided between the folding handle and the handle connecting part. The telescopic spring has the tendency to make the limiting block lock in the positioning groove.
[0005] According to the above technical solution, when the user rotates the folding handle, the limiting block moves along the arc-shaped limiting track. When the folding handle and the handle connection part are in a straight line, under the elastic force of the telescopic spring, the limiting block engages in the positioning groove at one end of the arc-shaped limiting track, and the folding handle is positioned and in use. When storing, the user disengages the limiting block from the positioning groove, thereby causing the folding handle to rotate and move closer to the main body of the product.
[0006] Alternatively, the middle of the handle connection part is hollowed out, and the folding handle is hinged in the hollowed-out structure. The arc-shaped limiting track is set on the inner side wall of the handle connection part, and the limiting block is set on the outer side wall of the folding handle.
[0007] As described above, the hinge shaft is located on the handle connection part. The folding handle has a strip-shaped shaft hole, and the telescopic spring is located in the internal cavity of the folding handle, connecting to the hinge shaft that mates in the strip-shaped shaft hole. When the user rotates the folding handle, the telescopic spring rotates accordingly. When the folding handle and the handle connection part are in a straight line, the limiting block engages in the positioning groove at one end of the arc-shaped limiting track, and the handle is in the use state. When the folding handle is needed, the user pulls down the folding handle to disengage the limiting block from the positioning groove before rotating the folding handle. When the folding handle is close to the main body of the product, the limiting block engages in the positioning groove at the other end of the arc-shaped limiting track, and the handle is in the retracted state. When the handle is needed, the user pulls the folding handle to disengage the limiting block from the positioning groove before rotating the folding handle downwards.
[0008] Alternatively, the folding handle has a hollowed-out center, with the handle connection part hinged in the hollowed-out structure. The arc-shaped limiting track is set on the outer side wall of the handle connection part, and the limiting block is set on the inner side wall of the folding handle.
[0009] As described above, the hinge shaft is located on the folding handle. The handle connection part has a strip-shaped shaft hole, and the telescopic spring is located in the internal cavity of the handle connection part, connecting with the hinge shaft that fits in the strip-shaped shaft hole. When the user rotates the folding handle, the telescopic spring will not rotate accordingly. When the folding handle and the handle connection part are in a straight line, the limiting block engages with the positioning groove at one end of the arc-shaped limiting track, and the handle is in the use state. When the handle needs to be folded, the user pulls down the folding handle to disengage the limiting block from the positioning groove before rotating the handle. When the folding handle is close to the product body, the telescopic spring exerts a spring force on the hinge shaft pointing towards the product body, thus pressing the folding handle firmly against the product body, and the handle is in the retracted state. When the handle needs to be used, the user rotates the folding handle downwards.
[0010] Alternatively, the hinge shafts on the folding handle are a pair of half-shafts, integrally formed on the folding handle. A recessed groove is provided on the outer wall of the handle connection portion, the arc-shaped limiting track forms the sidewall of the recessed groove, the strip-shaped shaft hole is located in the recessed groove, and the recessed groove has a clearance notch. A locking block is engaged with the handle connection portion, and the locking block closes the clearance notch. During assembly, the pair of half-shafts enter the recessed groove through the clearance notch, then engage with the strip-shaped shaft hole. The telescopic spring is installed into the internal cavity of the handle connection portion. After completion, the locking block is engaged with the handle connection portion, closing the internal cavity and the clearance notch.
[0011] The handle of this product can be folded and stowed, which facilitates product storage and transportation. Moreover, the handle is effectively limited when folded and in use. Attached Figure Description
