Abstract
The invention discloses a fan and a locking device of a front mesh enclosure and a back mesh enclosure of the fan. The locking device of the front mesh enclosure and the back mesh enclosure comprises a C-shaped locking ring which is used for surrounding a buckle connection position of the front mesh enclosure and the back mesh enclosure and is provided with an opening. Two end heads of the locking ring are matched through connection in an inserting mode. Long holes which extend along the circumference of the locking ring in the length wise direction and penetrate two end faces of a locking ring body in the depth wise direction are respectively arranged in the two end heads which are matched through the connection in the inserting mode, the two end heads of the locking ring are connected together through a wedge-shaped locking block which is arranged in the long holes in a penetrating mode and is matched with the long holes in a rotation stop mode. At least one of two side surfaces, facing hole ends of the long holes, of the locking block is a wedge-shaped inclined surface of the locking block, the locking block is fixedly connected with the locking ring through a bolt which is arranged on a small end face of the locking block in a rotation mode, and the locking ring drives the locking block to move in the long holes along with the rotation of the bolt, so that hole shrinkage of the locking ring is achieved. The two side surfaces of the locking block are respectively contacted with and cooperated with the hole ends, adjacent to the opening, of the long holes of the two end heads of the locking ring when the locking ring is tightened.

Fan generally comprises front mesh enclosure and rear net cover; fan screen has the effect of protection flabellum and personal safety; therefore the locking device of front mesh enclosure and rear net cover is extremely important, and before and after fan of the prior art, the locking device of guard mainly comprises plastic latch collar mechanism and hasp mechanism.Hasp mechanism is installation activity hasp on fan screen edge therein, fixes by the mode and another guard that fasten, although hasp mechanism is durable, and the easy not tight problem of appearance fastening in use; Plastic latch collar mechanism is around a plastic latch collar with C shape opening in guard make-up junction, fan front and back, this plastic latch collar inboard radially is provided with groove, before and after fan, the outer rim of guard projection is fastened in groove, then by plastic button, the two ends that C moulds the material clamp ring are coupled together, thereby before and after making fan, guard is locked.Although this plastic ring locking mechanism is simple in structure, in use can't adjusting tightness, when the plastic latch collar expand with heat and contract with cold will make fan when becoming slack before and after guard can not get locking.
Summary of the invention
The object of the present invention is to provide a kind of fan that can regulate the clamp ring elasticity.Simultaneously, the present invention also provides the locking device of guard before and after this fan.
for achieving the above object, before and after fan of the present invention, the locking device of guard adopts following technological scheme: the locking device of guard before and after fan, comprise be used to being looped around guard make-up junction, fan front and back, C shape clamp ring with opening, peg graft and coordinate in two terminations of described clamp ring, being respectively equipped with length direction on two terminations that this grafting coordinates circumferentially extends along clamp ring, depth direction runs through the slotted hole of two end faces of clamp ring circle body, two terminations of clamp ring are by being located in slotted hole, only screwing with slotted hole the wedge lock piece that closes links together, at least one in two sides of slotted hole nose end of described locking block is for forming the inclined-plane of locking block wedge shape, locking block is fixedly connected in clamp ring by the bolt that is screwed on locking block small end end face, clamp ring pulls locking block movement in slotted hole to realize that undergauge tightens up with the rotation of described bolt, described two sides of locking block coordinate with the corresponding contact of nose end of the close opening of the slotted hole of clamp ring two terminations respectively when clamp ring is tightened up.
One of them is " recessed " character form structure, another " protruding " character form structure for coordinating with the termination grafting of " recessed " font for two terminations that described grafting coordinates.
The size of the large end end face of described locking block on the slotted hole length direction is less than the length of slotted hole, and the height of described locking block is not more than the thickness of clamp ring.
Be provided with external diameter between the head of described bolt and clamp ring greater than the pad of slotted hole width.
fan of the present invention adopts following technological scheme: fan, comprise front mesh enclosure, the locking device of rear net cover and front and back guard, the locking device of front and back guard comprises be used to being looped around guard make-up junction, fan front and back, C shape clamp ring with opening, peg graft and coordinate in two terminations of described clamp ring, being respectively equipped with length direction on two terminations that this grafting coordinates circumferentially extends along clamp ring, depth direction runs through the slotted hole of two end faces of clamp ring circle body, two terminations of clamp ring are by being located in slotted hole, only screwing with slotted hole the wedge lock piece that closes links together, at least one in two sides of slotted hole nose end of described locking block is for forming the inclined-plane of locking block wedge shape, locking block is fixedly connected in clamp ring by the bolt that is screwed on locking block small end end face, clamp ring pulls locking block movement in slotted hole to realize that undergauge tightens up with the rotation of described bolt, described two sides of locking block coordinate with the corresponding contact of nose end of the close opening of the slotted hole of clamp ring two terminations respectively when clamp ring is tightened up.
One of them is " recessed " character form structure, another " protruding " character form structure for coordinating with the termination grafting of " recessed " font for two terminations that described grafting coordinates.
The size of the large end end face of described locking block on the slotted hole length direction is less than the length of slotted hole, and the height of described locking block is not more than the thickness of clamp ring.
Be provided with external diameter between the head of described bolt and clamp ring greater than the pad of slotted hole width.
The present invention puts into the wedge lock piece slotted hole of two terminations of clamp ring grafting cooperation, two terminations of clamp ring are linked together, when screwing bolt, wedge lock piece depth direction along slotted hole in slotted hole moves, because the inclined-plane of wedge lock piece coordinates with the corresponding contact of nose end of the close clamp ring opening of slotted hole, therefore in the process that locking block moves in slotted hole, exert pressure to the slotted hole nose end in the inclined-plane of locking block, make two terminations of clamp ring close, thereby clamp ring is tightened up, thereby before and after fan, guard just can be realized locking.The present invention only need to screw bolt just can regulate the elasticity of clamp ring, not only simple in structure, and easy to operate.
