Abstract

The utility model relates to a protective device of a complex saw, which consists of an outer protective cover, an inner protective cover, a rear protective plate, a seat cover and a base, wherein, the rear part of the outer protective cover is provided with a connecting rod; the inner protective cover is provided with a mounting hole, and the mounting hole is matched with the outer wall of the seat cover; the rear protective plate is fixed on the base; the inner protective cover is sleeved in the outer protective cover. The protective device of the complex saw has reasonable structure, appropriated and compact layout, and adopts spatial protection so that an operator is protected to a maximum extent during the operation; in addition, the inner protective cover and the outer protective cover are made of transparent material, thus the protective device is beautiful in appearance, and more importantly, the operator can pay attention to dangers at any time and make reasonable adjustments accordingly as soon as possible; furthermore, the rear protective plate can prevent fingers of the operator from touching a saw blade by accident, thereby the protective device of the complex saw has better protection effect.

Description

The protector of compound saw

Technical field

The utility model relates to a kind of electronic compound saw, the particularly protector of compound saw.

Background technology

Compound saw is a kind of electric tool commonly used; be widely used in the production; security protection is the most important thing of design always; common protector is that a protective cover directly is installed on framework at present; make it cover the part of saw blade; this kind protector is compared with suitable progress that saw blade is directly come out; but its protective position relative fixed; protection domain can not be done suitable adjustment with the cutting angle conversion of saw; protection can only reach intrinsic coverage in particularly using; can not adjust protection domain automatically along with operator's needs, occur accident repeatedly.

Summary of the invention

The potential safety hazard that the utility model in use exists in view of compound saw, the spy provides a kind of at any time can both adjust protection domain with the need automatically.

The technical solution of the utility model is: comprise outer protective cover, interior protective cover, rear wing, cover for seat, base, establish a linkage behind the outer protective cover; Interior protection is covered with installing hole, and the outer wall of installing hole and cover for seat cooperates; Rear wing is fixed on the base, and interior protective cover is nested in the outer protective cover.

Outer protective cover of the present utility model and interior protective cover are layered distribution, are installed on the saw blade both sides respectively, and its shell material adopts transparent material to make.The installing hole of interior protective cover becomes to be rotatably assorted with the outer wall of cover for seat.Linkage is formed by rotor and rod hinge connection; Rotor is anchored on the swivel base axle, and the connecting rod other end and arc plate are hinged, and arc plate is provided with and keeps off the hinged centre bore of bits sheet, and retaining bits sheet is fixed on the framework.Cover for seat is fixed on the framework.Rear wing is fitted mutually by the clamping plate rear end of two symmetries and is formed, and front end is a cavity, and the rear end is provided with solid top board, is fixed on the base by fixed head.The hinged rotation hole of connecting rod and arc plate is the adjustment hole of longitudinal.

The beneficial effects of the utility model are: the three-dimensional protection of compound saw makes the operator obtain the protection of maximum magnitude in using operation.The structure of outer protective cover and back protection in protection is adopted; Interior protective cover is positioned at the framework the inside; protective cover is close to workpiece all the time in during operation under the gravity effect; the outer outer protective cover of framework is the interlock protective cover; can adjust protection domain automatically with the pattern of compound saw; the interior outer protective cover of transparent material is elegant in appearance; make the operator observe the situation of protection at any time, make rational adjustment as early as possible, back shroud prevents that operator's finger accident collision is to saw blade.The utility model reasonable in design, layout is proper, compact, and protection effect is excellent.

The specific embodiment

Referring to accompanying drawing 1-3, present embodiment comprises outer protective cover 1, interior protective cover 2, rear wing 3, cover for seat 4, base 9, establishes a linkage 7 behind the outer protective cover 1; Interior protective cover 2 is established installing hole 21, and the outer wall 41 of installing hole 21 and cover for seat 4 cooperates; Rear wing 3 is fixed on the base 9, and interior protective cover 2 is nested in the outer protective cover 1.Interior protective cover 2 and outer protective cover 1 are inside and outside two-layer distribution, are installed on the saw blade both sides respectively, and its shell material adopts transparent material to make, and the handled easily person observes the rotation situation of saw blade at any time; The installing hole 21 of interior protective cover 2 is rotatably assorted for 41 one-tenth with the outer wall of cover for seat 4.Linkage 7 is by rotor 71 and connecting rod 72 hinged forming; Rotor 71 is anchored on the swivel base axle 82, and the connecting rod other end and arc plate 73 are hinged, and arc plate 73 is provided with and keeps off the hinged centre bore 74 of bits sheet 10, and retaining bits sheet 10 is fixed on the framework 6.Cover for seat 4 is fixed on the framework 6.Rear wing 3 is fitted mutually by clamping plate 31 rear ends of two symmetries and is formed, and front end is a cavity, and the rear end is provided with solid top board 5, is fixed on the base 9 by fixed head 5.Connecting rod 72 is the adjustment hole of longitudinal with the rotation hole 75 that arc plate 10 is hinged.

When the utility model uses; the saw blade front end of rotation has outer protective cover 1, interior protective cover 2 at a high speed; outer protective cover 1; the saw blade upper end is positioned at framework 6; the saw blade rear end is positioned at the cavity of back screening glass 3, because the installing hole 21 of interior protective cover 2 and the outer wall of cover for seat 4 are rotatably assorted for 41 one-tenth, interior protective cover 2 is close to workpiece under the gravity effect when tiltedly sawing pattern; during the further incision of saw blade, outer protective cover is adjusted protection domain automatically under the effect of linkage 7.The protector of this compound saw forms three-dimensional protection, makes the operator in use obtain the protection of maximum magnitude.
