Abstract
The utility model relates to a cutting saw with a safety shield, which comprises a base for containing a workpiece to be cut; a supporting arm is hinged on the base; the supporting arm is provided with a power head; the power head drives a rotatable saw bit; and a fixed shield and a movable shield cover on the saw bit. The cutting saw is characterized in that one end of a shield connecting rod is hinged with the movable shield, and the other end of the shield connecting rod is connected with a locating pin structure. The utility model has the advantages that on the premise of ensuring the original turnup movement performance of the movable shield, a cutting blade is protected in the whole cutting operation process.
Description
Technical field
The utility model relates to a kind of saw of cutting with safety guard.
Background technology
The common element of cutting saw comprises: be used to place the base of workpiece to be cut, hinged support arm on base is placed in the unit head on the support arm and drives rotatable saw blade by unit head.When the startup unit head makes the saw blade rotation, press down handle, can make saw blade cut the workpiece that is supported on the base on demand.
In order to guarantee handling safety, the saw blade first half and Lower Half are covered with secure shroud and movable shield respectively.The structure of comings and goings guard shield is to disclose respectively among ZL200720043502.8 and the US5893311 in the patent No..Wherein, fan-shaped geometric center and saw blade axis that typical structure is the sector movable guard shield form revolute pair, the cover body precalculated position of this movable shield and an end of guard shield connecting rod are hinged, have the straight trough consistent with the connecting rod bearing of trend near the other end of this guard shield connecting rod, near the alignment pin the hinged point of this straight trough and support arm constitutes moving sets.
In carrying out cutting operation process, when pressing down handle, aforementioned link mechanism is rotated the connection movable shield, makes it overlapping with secure shroud gradually, exposes saw blade, so that cut workpiece; And when lifting handle, aforementioned link mechanism loses the connection to movable shield, under the effect of reduction torsion spring, it is resetted gradually, is returned to the position involutory with secure shroud, saw blade is covered fully, thereby avoid saw blade to cause unexpected injury.Owing to consider that saw blade is a wearing detail, when needs are changed, the guard shield connecting rod can be lifted, make near the alignment pin of the hinged point of support arm be in the inner of guard shield connecting rod straight trough relatively, thereby can upwards dig movable shield, give and change the saw blade turnover space that saw blade is abdicated necessity.
Summary of the invention
The purpose of this utility model provides a kind of saw of cutting of protecting cutting blade in operating process fully.
In order to achieve the above object, the technical solution of the utility model has provided a kind of saw of cutting with safety guard, comprise the base that is used to place workpiece to be cut, support arm is hinged on base, is provided with unit head on support arm, and unit head drives rotatable saw blade, on saw blade, be covered with secure shroud and movable shield, it is characterized in that an end and the movable shield of guard shield connecting rod are hinged, the other end connects locating pin structure.
Further, described locating pin structure comprises link assembly and opens groove on secure shroud, one end of link assembly links to each other with described support arm, the connecting rod axial screw passes described guard shield connecting rod, link assembly and the groove opened on secure shroud links together three parts, and sliding in groove by the connecting rod axial screw forms moving sets.
Described link assembly comprises adjutage, and adjutage is located on the described support arm, has rotatable must the linking to each other with adjutage of an end of the adjutage connecting rod of microscler groove, is equipped with described connecting rod axial screw in the other end.
Like this, when pressing down handle when carrying out cutting operation,, guaranteed handling safety because the effect of locating pin structure can the connection movable shield be dug gradually.
The utility model has the advantages that: guaranteeing that movable shield is original digs under the performance prerequisite whole process protection cutting blade in the cutting operation process.
Description of drawings
Fig. 1 is a cut state structural representation of the present utility model;
Fig. 2 is the structural representation of non-cut state of the present utility model.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
As depicted in figs. 1 and 2, present embodiment cut saw mainly by the base 4 that is used to place workpiece to be cut, by jointed shaft 10 hinged on base support arm 11, be placed in unit head on the support arm 11, drive rotatable saw blade 5 and handle 1 is formed by unit head.Securing elongated arm 13 on the support arm 11, the upper end of this adjutage 13 are equipped with from the not far dog screw 14 of jointed shaft 10.The outside of saw blade 5 is covered with synthetic back and is the fan-shaped secure shroud 2 of full circle and movable shield 3 substantially, the geometric center of movable shield 3 and reduction torsion spring 7 and saw blade center of rotation, be unit head rotating shaft 6 in be formed centrally revolute pair, its cover body is hinged near an end of center position and guard shield connecting rod 8, the other end, lower end of a connection movable shield 3 of reduction torsion spring 7 is connected and fixed the rear end of guard shield 2, the revolute pair that reduction torsion spring 7 is produced is opposite with the direction that movable shield 3 is dug, one end of guard shield connecting rod 8 is made the arc elbow of stepping down, the other end has a through hole, pass the through hole of guard shield connecting rod 8 one ends by connecting rod axial screw 9, pass the through hole that the L shaped groove of being opened on the secure shroud 2 passes adjutage connecting rod 12 1 ends again, guard shield connecting rod 8, secure shroud 2, adjutage connecting rod 12 3 parts connect together, slide in L shaped groove by connecting rod axial screw 9 and to constitute moving sets, the other end of adjutage connecting rod 12 has microscler groove, by dog screw 14 it is connected on the adjutage 13 and constitutes revolute pair.
When pressing down cutting by handle 1, because connecting rod axial screw 9 slides in L shaped groove, therefore can connection movable shield 3 dig gradually, as shown in Figure 1, saw blade 5 contacts with workpiece.After lifting handle 1, because the active force connection movable shield 3 of reduction torsion spring 7 falls gradually, as shown in Figure 2, be fixed guard shield 2 and movable shield 3 of saw blade 5 covers fully.When changing saw blade, if make adjutage connecting rod 12 by dog screw 14 along sliding into the position, back in the microscler groove of adjutage connecting rod 12 1 ends, as shown in Figure 3, this moment, movable shield 3 was dug as required, abdicated necessary saw blade and passed in and out the space.
