Abstract
The utility model relates to a pitching mechanism. The pitching mechanism comprises a rear net part and a support part used for supporting the rear net part. The rear net part comprises a cylindrical support and an annular net body supported on the cylindrical support. The whole support part is in a U shape. The top ends of the left and right sides of the support part are provided with a left installation head and a right installation head. The left installation head and the right installation head are provided with inner holes and are symmetric to each other. A large spring and a gland pressing the large spring are arranged inside the outer side of the inner hole of the left installation head. The pitching mechanism has the advantages of being quite simple and practical, and having the quite obvious effect of preventing a box-type fan from automatically dropping the head.
Description
Technical field
The utility model relates to a kind of luffing mechanism, in particular, relates to a kind of luffing mechanism of box fans.
Background technique
Existing box fans, because center of gravity is not on intermediate support, causes existing box fans to have the hidden danger of automatically bowing, and Consumer in use often has the worries that cannot locate luffing angle.
Model utility content
The technical problems to be solved in the utility model is, the above-mentioned defect for prior art, provides a kind of luffing mechanism and fan.
The utility model solves the technological scheme that its technical problem adopts: a kind of luffing mechanism, comprises rear mesh portions and for supporting the holder part of described rear mesh portions; Described rear mesh portions comprises cylindric bearing and is supported in the annular dictyosome on described cylindric bearing; Described holder part overall U-shaped, is provided with the left mounting head with endoporus and the right mounting head of mutual symmetry on its top, left and right sides, the gland that is provided with big spring and pushes down described big spring in the endoporus outside of described left mounting head.
Described holder part is also provided with the left installation sheet corresponding with described left mounting head and the right installation sheet corresponding with described right mounting head simultaneously; From described left installation sheet middle part, protrude left boss, from described right installation sheet middle part, protrude right boss, described left boss and right boss match with the endoporus inner side of described left mounting head and right mounting head through the through hole described cylindric bearing from described cylindric bearing inner side.
Between described right mounting head inner side and the described right boss of described right installation sheet, be provided with slide, in hole on described right boss, there are two little springs that help out, described little spring matches with the corresponding hole of slide, and two little steel balls are placed in respectively on a side of described two little springs and described slide between corresponding hole.
By screw rod and nut, successively described right installation sheet, slide are fixed in the described right mounting head of described holder part.
The beneficial effect that the utility model is reached is: this luffing mechanism is very succinct practical, prevents that the effect that box fans bows is automatically very obvious.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the blast structural representation of the preferred embodiment of the utility model luffing mechanism;
Fig. 2 is the structural representation of the big spring of preferred embodiment in the utility model luffing mechanism;
Fig. 3 is the structural representation after the installing of preferred embodiment of the utility model luffing mechanism.
Embodiment
As Figure 1-3, a kind of luffing mechanism, comprises rear mesh portions 1 and for supporting the holder part 8 of rear mesh portions 1; Rear mesh portions 1 comprises cylindric bearing 1-1 and is supported in the annular dictyosome 1-2 on cylindric bearing 1-1; Holder part 8 overall U-shaped, are provided with the left mounting head 8-2 with endoporus and the right mounting head 8-3 of mutual symmetry on its top, left and right sides, the gland 23 that is provided with big spring 22 and pushes down big spring 22 in the endoporus outside of left mounting head 8-2.
Between right mounting head 8-3 inner side and the right boss 31 of right installation sheet 3, be provided with slide 38, in hole on right boss 31, there are two little springs that help out 37, little spring 37 matches with the corresponding hole of slide 38, and two little steel balls 35 are placed in respectively on a side of two little springs 37 and slide between corresponding hole.
By screw rod 34 and nut 36, successively right installation sheet 3, slide 38 are fixed on the right mounting head 8-3 of holder part 8.
As shown in Figure 2, when luffing mechanism has the trend of automatically bowing, big spring 22 can produce a reaction force to the structure of left big spring 22, acts on rear mesh portions 1, to reach, prevent that rear mesh portions 1 is overweight, center of gravity before partially and the object of bowing.And little spring 37 and little steel ball 35 play auxiliary big spring 22 in this process, also can provide certain reaction force.
The diameter of little steel ball 35 is larger than the internal diameter of little spring 37, when after Manual press, mesh portions 1 is carried out pitching action, 35 of slide 38 and little steel balls can produce a power of cutting sth. askew, little steel ball 35 extruding little springs 37, little steel ball 35, along tabbing between slide 38 hole thereon, produces kaka sound.
This luffing mechanism is very succinct practical, prevents that the effect that box fans bows is automatically also very obvious.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
