Abstract
The utility model relates to a safety device for a circular saw blade protecting cover of a circular sawing machine. The side end of a supporting seat of a base of a circular sawing machine is pivoted with a connecting sheet and a Y-shaped connecting rod, wherein a long sliding chute is arranged on the Y-shaped connecting rod; the top edge of the supporting seat is pivoted with a handle and an upper protecting cover of a saw blade; a lower protecting cover is arranged on a corresponding position of the upper protecting cover; the shaft center of the lower protecting cover is embedded with a circular fixing plate; a screw bolt penetrates among the long sliding chute, the circular fixing plate, the lower protecting cover, the upper protecting cover and the handle and slides along the long sliding chute. The utility model is characterized in that the top edge of the terminal end of the long sliding chute is concavely provided with a clamping hole which can be used for clamping the screw bolt. The utility model has the function that the protecting covers are forced to be reset and clamped so that the protecting covers can not be lifted, therefore the effect of safe operation can be obtained.
Description
The utility model relates to the safety device of the saw blade protecting cover of circular sawing machine.
Circular sawing machine is carpenter's indispensable facility, and the saw blade of traditional circular sawing machine is not established the protecting cover protective device, and is careless slightly in the use, very easily causes sudden hurt accident.The inventor creates a kind of saw blade holding protective cover device of circular sawing machine; and it is disclosed by Taiwan patent announcement 276575; as shown in Figure 1; it comprises protecting cover 30 down; Y type connecting rod 10; fixed head 35; the one interlock structure that last protecting cover 20 and pulley 21 etc. constitute; by the interlock of pulling of the top between the pulley 21 of Y type connecting rod 10 and last protecting cover 20; make the microscler chute 11 of Y type connecting rod 10 progressively guide protecting cover 30 and fixed head 35 pressure playback down; play the safety operation effect; its major defect is this time protecting cover 30 no blocking structures; started easily in the use; and lose the safeguard protection effect, and saw blade is exposed fully, cause sudden hurt accident.
The purpose of this utility model is to provide a kind of safety device of saw blade protecting cover of circular sawing machine, supporting seat side at the circular sawing machine base articulates brace and Y type connecting rod, microscler chute apical margin at Y type connecting rod is arranged with the blocking hole, protecting cover is slided in the microscler chute relatively by bolt, have the effect of forcing its playback and blocking not to start, reach purpose safe in utilization.
The purpose of this utility model is achieved in that
Major advantage of the present utility model is: owing to be arranged with the blocking hole at the apical margin of the microscler chute of the Y type connecting rod that is hubbed at the circular sawing machine base, following protecting cover slides in the microscler chute relatively by bolt, have protecting cover playback and its effect that can not start of blocking down forced, prevent down that protecting cover is started by improper, has effect safe in utilization.
Further specify below in conjunction with preferred embodiment and accompanying drawing.
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of brace of the present utility model and Y type connecting rod;
Fig. 4 is the enlarged diagram of partial structurtes of the present utility model;
Fig. 5 is a blocking action schematic diagram (part) of the present utility model.
Consult Fig. 2-Fig. 5, the utility model is articulated with brace 15 and Y type connecting rod 10 at the side of the supporting seat 42 of circular sawing machine base 40, microscler chute 11 terminal apical margin appropriate locations at Y type connecting rod 10 are arranged with blocking hole 12, supporting seat 42 apical margins by 21 be pivoted handle 25 and saw blade 50 on protecting cover 20, protecting cover 20 relative positions are provided with down protecting cover 30 on the correspondence, place, axle center at following protecting cover 30 is embedded circular fixed head 35, this circle fixed head 35 is arranged in the microscler chute 11 by bolt 36, make circular fixed head 35 and following protecting cover 30 relative sliding in the microscler chute 11, force protecting cover 30 playback down.
The utility model is arranged with the blocking hole 12 that can supply bolt 36 embedding systems at the appropriate location of microscler chute 11 terminal apical margins, when in using, upwards starting down protecting cover 30 because of improper operation, bolt 36 on its circular fixed head 35 can slide to blocking hole 12 immediately, forms the blocking phenomenon and can't will descend protecting cover 30 to start (as shown in Figure 5).Thereby improve the effect safe in utilization of circular sawing machine.
Using method of the present utility model is as follows: when the user pressed down handle 25, bolt 36 slided to supporting seat 42 along microscler chute 11, and drove lower jacket 30 and be pulled upwardly, and can saw the material operation; When handle 25 pull-ups, bolt 36 slides to the terminal apical margin of microscler chute 11, and drives protecting cover 30 covering saw blades 50 down, forms the safeguard protection effect; This moment, if bolt 36 slided in the blocking hole 12 immediately when desiring to start lower cover 30, formed the blocking phenomenon and can't will descend protecting cover to start, and prevented that sudden hurt accident from taking place.
Claims (1)
1, a kind of safety device of saw blade protecting cover of circular sawing machine, the supporting seat side that is included in the circular sawing machine base articulates brace and Y type connecting rod, this Y type connecting rod is provided with microscler chute, the last protecting cover of this supporting seat apical margin axle pivot handle and saw blade, should go up the protecting cover relative position and be provided with down protecting cover, the place, axle center of this time protecting cover is embedded circular fixed head; Bolt is arranged in this microscler chute, circular fixed head, following protecting cover, goes up between protecting cover and the handle and slide along this microscler chute, it is characterized in that the apical margin of this microscler chute end is arranged with the blocking hole that can supply this bolt embedding system.
