Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, a screwing type fixing foot structure is used for being assembled on a product bottom surface 10 and comprises a fixing foot body 1, wherein an upper boss 11 and a lower boss 12 are respectively arranged on a top supporting surface and a bottom supporting surface of the fixing foot body 1, a support frame 2 is fixedly arranged at the center of the upper boss 11, and a through hole 3 matched with the support frame 2 for use is arranged on the product bottom surface 10.

In this embodiment, set up the through-hole on the product bottom surface, set up the support frame on the fixed foot body, penetrate the support frame is whole from the through-hole when using for inside the support bar is located the product, clockwise rotation 90 degrees with fixed foot again just can make support bar fixing clip between product bottom surface and fixed foot body, thereby play the effect of assembling fixed foot on the product bottom surface. The assembling mode is simple and easy to operate, the labor input cost can be reduced, and meanwhile, the assembling efficiency of the fixing foot can be effectively improved.

Optionally, the supporting frame 2 is composed of a protrusion 21 and a supporting bar 22 fixed on the protrusion 21, the shape of the protrusion 21 projected onto the upper protrusion is composed of a rectangle and two circular arcs, and the straight edge 210 of the protrusion 21 is parallel to the long edge 220 of the supporting bar 22. Through the structure, the placing direction of the supporting bar can be judged according to the placing direction of the convex block when the supporting frame penetrates through the through hole, so that the supporting bar can smoothly penetrate through the through hole.

Optionally, the shape of the through hole 3 is composed of a rectangle and two circular arcs respectively protruding outwards from the middle of two long sides of the rectangle, and the circular arc of the through hole 3 is the same as the circular arc of the shape projected onto the upper boss by the bump 21. Through above-mentioned structure, after the support bar passed the through-hole, the circular arc limit on the boss just can just contact the chucking with the circular arc limit of through-hole after with fixed foot clockwise rotation 90 degrees, prevented that fixed foot from taking place not hard up at the removal in-process, further reinforcing the fixed stability of fixed foot.

Optionally, the width of the protrusion 21 is equal to the width of the supporting bar 22, and the length of the supporting bar 22 is equal to the length of the through hole 3. Through above-mentioned structure, because the product bottom plate has certain thickness, consequently want to make the support bar all be located the product in, must have some lug and product bottom plate cross-section contact so, consequently set up the width of lug to equal can be when the support frame penetrates unrestricted smooth the passing in to the through-hole with the width of support bar.

Optionally, the bottom surfaces 221 of the two ends of the supporting strip 22, which are not in contact with the protrusions 21, are inclined planes, and the distance between the lowest point 222 of the two ends of the supporting strip 22 and the top surface 110 of the upper boss 11 is equal to the thickness of the bottom surface 10 of the product. The setting of above-mentioned structure makes fixed foot rotatory relatively smooth, can guarantee moreover that the support bar contacts and the chucking with the medial surface of product bottom surface, and the incline direction of the bottom surface at support bar and the contactless both ends of lug has two kinds in this embodiment, according to the incline direction of difference, according to particular case clockwise rotation 90 degrees or anticlockwise rotation 90 degrees when fixed foot assembly.

Alternatively, the bottom surfaces 221 of the two ends of the supporting bar 22, which are not in contact with the protrusions 21, are inclined at the same angle, and the inclination directions of the two bottom surfaces are opposite.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications described in the claims and the specification of the present invention are included in the scope of the present invention. In addition, the abstract and the title are provided for assisting the search of patent documents and are not intended to limit the scope of the present invention.
