Preferably, a positioning ring is arranged on the fixing shaft on the inner side of the fixing hole.

The utility model has the advantages that:

fixing lugs are arranged on two sides of the lamp body, fixing holes are formed in the fixing lugs, the fixing shafts are inserted into the fixing holes, the fixing holes are regular polygons, the number of sides of each regular polygon is 3N, N is an integer, N is more than or equal to 2 and less than or equal to 5, and an isosceles triangle open slot is formed in the middle of each straight side of each fixing hole; the end surface of the outer end of the fixed shaft is an equilateral triangle, and the end surface of the inner end of the fixed shaft is circular; when the fixed shaft rotates in the fixed hole, the circular end surface part of the fixed shaft is tightly attached to each side of the fixed hole, and the circular end surface part of the fixed shaft plays a role in supporting and centering the rotation of the fixed shaft; the vertex angles of the triangular end surface part of the fixing shaft are correspondingly arranged in the open slots, the fixing shaft is stopped by the open slots because the silica gel layer has certain resilience, and when the lamp body is rotated by hands or the hinged frame is hinged, the vertex angles of the triangular end surface part of the fixing shaft can be rotated out of the open slots because of the extrudability of the silica gel layer.

Therefore, the utility model discloses the articulated shaft is rotatable, and when the apex angle card of the triangle-shaped terminal surface part of fixed axle goes into corresponding open slot, the fixed axle is stopped, and when rotating the fixed axle with the hand, the open slot can be rolled out to the apex angle of the triangle-shaped terminal surface part of fixed axle, the utility model discloses simple structure, the rotation of articulated frame, fixed convenient operation that uses.

Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make more clear and definite definitions of the scope of the present invention.

Referring to the attached drawings 1 to 4 in the specification, a square hinge frame 2 with an opening at one end is arranged at the rear part of a lamp body 1, the lamp body is arranged between two opening ends of the hinge frame, the opening ends of the hinge frame 2 are respectively provided with a fixing shaft 21, two sides of the lamp body 1 are provided with fixing lugs 11, the fixing lugs 11 are provided with fixing holes 12, the fixing shafts 21 are inserted into the fixing holes 12, the fixing holes are regular hexagons, the number of gear shifting of the hinge frame is increased along with the number of sides of the regular polygons, the number of transposition gears is increased, and an isosceles triangle open slot 121 is arranged in the middle of each straight side of; the end face of the outer end of the fixed shaft 21 is an equilateral triangle, the end face of the inner end of the fixed shaft is circular, the outer surface of the fixed shaft is covered with a silica gel layer 22, the circular end face of the fixed shaft is an inscribed circle of the fixed hole, when the fixed shaft rotates in the fixed hole, the circular end face part of the fixed shaft is tightly attached to each side of the fixed hole, the circular end face part of the fixed shaft plays a supporting and centering role for the rotation of the fixed shaft, the distance from the central point of the triangular end face of the fixed shaft to the vertex angle is equal to the distance from the central point of the end face of the fixed hole to the bottom angle of the open slot of the corresponding side and is larger than the distance from the central point of the end face of the fixed hole to the corresponding side and does not exceed the central point of the end face of the fixed hole to the vertex angle of the corresponding triangular open slot, because of the extrudability of the silica gel layer, the vertex angle of the triangular end surface part of the fixed shaft can be rotated out of the open slot.

Furthermore, a positioning ring 23 is arranged on the fixing shaft 21 on the inner side of the fixing hole, and plays a role in fixing and preventing the fixing shaft from falling off, so that the hinged frame is prevented from shaking in the axial direction of the fixing shaft.

To reduce wear during rotation, the bottom corners 1211 of the open slot are rounded and the top of each vertex of the triangular end surface of the stationary shaft is rounded.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred embodiments of the present invention, and the present invention is not limited by the above preferred embodiments, and various changes and modifications can be made without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the present invention as claimed.
