Description

The Electric fan protective net clamping and drawing device

The utility model relates to the protecting wire net clamping and drawing device, particularly relate to and a kind ofly have protruding lip, convex body, fastening recess and eye-splice, middle ring that preceding net can be fastened and the simple rapid Electric fan protective net clamping and drawing device of the assembling that clamping and drawing device constituted that includes auricle, fastening piece thereof by inner face.

The structure of normally used Electric fan protective net clamping and drawing device such as Fig. 1, Fig. 2, shown in Figure 3 are to be formed by middle ring (1), front flat edge (2), back flat edge (3) and clamping and drawing device (4) structure; Wherein, should have protruding lip (11) and some convex bodys (12) by middle ring (1) inner face, make and form a circular rabbet (13) between protruding lip (11) and convex body (12), snap in for front flat edge (2), convex body then has shrinkage pool on (12), be the eye-splice (14) and the fastening device (4) of concave shape with cooperation, back flat edge (3) snapped in and clip is fixed; This fastening device (4) comprising: fastening piece (40), one end have a oblique crank Z bar (41), with in the  shape hole (15) that penetrates middle ring (1) and pivot joint location, as the pivot point of fastening piece (40); The other end has clamping sheet (42) and block holder (43), snaps in the clip hole (16) of middle ring (1) respectively and fastens back flat edge (3); Other has a spiral shell spare (44), but spiral shell is worn the perforation (171) of lug (17) upper end on the middle ring (1), and is pressed on fastening piece (40) end face.The prior art structure of above-mentioned Electric fan protective net clamping and drawing device, though firmly, yet when assembling (or dismounting), need spiral shell spare (44) to be screwed tight or the spiral shell pine by instrument (screwdriver), obviously rather trouble inconvenience expends assembling manpower and man-hour.

The purpose of this utility model is, a kind of easy Electric fan protective net clamping and drawing device is provided, and is formed by a ring and a clamping and drawing device structure in one, and ring inner face has protruding lip, convex body, fastening recess and eye-splice in this, front flat edge can be fastened; Clamping and drawing device then comprises: an auricle, and ring is last and corresponding with eye-splice in the outstanding what of consubstantiality, has a rectangle slotted eye, and its inboard has a projection above the rectangle slotted eye, and then respectively there is an alcove both sides, bottom; Fastening piece slightly is

Shape, its upper end is a plate, the middle slide block that protrudes, can slip over the rectangle slotted eye of auricle and engage with projection, the both sides, bottom respectively have a piece, can snap in the alcove, so that fastening piece is located, and can be used as the rotating fulcrum of fastening piece, have between the diaxon piece-clipping block, but net behind the clip, and said structure is simple convenient rapidly, but economization assembling manpower and man-hour, overcome the inconvenient shortcoming of existing structure assembling trouble.

The purpose of this utility model is achieved through the following technical solutions: the utility model is mainly formed by middle ring (1) and clamping and drawing device B structure, middle ring (1) inner face has fastening recess (circular rabbet) (13) and the eye-splice (14) that forms between protruding lip (11), convex body (12), protruding lip and the convex body, front flat edge can be fastened; It is characterized in that: the main structure that is arranged on the clamping and drawing device B on the middle ring (1) comprises: ring (1) is last and corresponding with eye-splice (14) in the outstanding what of auricle (5) consubstantiality, has a rectangle slotted eye (51), there is a projection (52) its inboard above the rectangle slotted eye, then respectively there is an alcove (53) both sides, bottom; And fastening piece (6), be Shape, its upper end is plate (61), middle outstanding slide block (62), can slip over the rectangle slotted eye (51) of auricle (5) and engage with projection (52), respectively there is a piece (63) both sides, bottom, can snap in the alcove (53), so that fastening piece (6) is located, and, clipping block (64) is arranged between the diaxon piece (63) as the rotating fulcrum of fastening piece, be used for clip back flat edge (3).

Narrate the utility model embodiment below in conjunction with accompanying drawing:

During assembling, as long as fastening piece (6) is penetrated from rectangle slotted eye (51), and the application of force snaps in two alcoves (53) two pieces (63) slightly, fastening piece (6) can be located, plate (61) that makes fastening piece (6) and slide block 62) outside of position what auricle, clipping block (64) then is positioned at inboard (state shown in Figure 6); And inwardly pull simultaneously plate (61), making fastening piece (6) is rotating fulcrum with axle piece (63), make slide block go in the rectangle slotted eye (51) and engage with projection (52), inwardly move simultaneously and by means of fan (3) behind vertical end face (65) pushing tow, make clipping block (64) clip back flat edge (state shown in Figure 7) downwards, and reach the pull purpose in jail of fan network interface card.Wherein this fastening piece (6) is hollow state because of the centre, can make its upper end plate (61) have elasticity in order to pulling, intermediate slider (62) then has pushing face-drawing, can be with pulling pulling and slipping over the rectangle slotted eye (51) of auricle (5) easily of sheet (61), and with projection (52) engaging or separate, diaxon piece (63) is to place in the alcove (53), can be used as the pivot point of fastening piece (6), clipping block (64) then is hanging shape and tool elasticity slightly, and its front end is to push away and pulls out cambered surface, but clip back flat edge (3).

When dismounting, as long as plate (61) is outwards pulled open, make slide block (62) skid off the rectangle slotted eye (51) of auricle and separates with projection (52), the while also drives clipping block (64) and breaks away from no longer clip back flat edge (3), and recovery original state as shown in Figure 6, can unload the fan net easily this moment.

When advantage of the present utility model and effect are to implement assembling, need not utilize any instrument, Outline is executed thrust snaps in the alcove (53) of auricle, namely two axle pieces (63) of fastening piece (6) Plate (61) can be pulled simultaneously again in fastening piece (6) location, just can borrow clipping block (64) with rear fan Net (3) clip location, obviously quite simply rapidly again convenient, not only can reach the fan network interface card is pulled Purpose firmly, but and economization assembling manpower and man-hour.
