Description
Technical field
The utility model relates to bench saw equipment, is specifically related to the fast locking device of a kind of protective cover.
Background technology
In bench saw equipment, protective cover shrouds around blade, mainly is divided into carriage, left protective cover, right protective cover three parts, and wherein, carriage is connected with following knife plate.Carriage with usually adopt and removably connect with knife plate, the connected mode in the past once adopted or need to utilize instrument to be dismantled and install, time-consuming effort again, and the parts depreciation of connecting portion is serious, affects service life; Although perhaps do not need to utilize instrument, dismounting and the operating procedure of installing are all too loaded down with trivial details.
Summary of the invention
The utility model is in order to simplify the dismounting step of protective cover, thereby the dismounting speed of quickening protective cover has been invented the fast locking device of a kind of protective cover, and this fast locking device has realized exempting from the singlehanded dismounting of instrument, very convenient.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs: the fast locking device of a kind of protective cover, comprise with knife plate, connect the protective cover carriage with the knife plate top, the both sides of protective cover carriage connect protective cover, it is characterized in that, the bottom of described protective cover carriage is provided with horizontal locking pin, connect lock handle on locking pin, go back one section locking spring of ring set on locking pin, the described top edge with knife plate is provided with connecting hole, this connecting hole upper end open, and the latter half of connecting hole is wider than the first half; Described locking pin be mutually perpendicular position with knife plate, locking pin for the part in the Snap joint hole, the height H of its cross section is greater than width B.
As preferably, the part in the Snap joint hole of described locking pin is arranged to the cylindricality of flattening.When locking pin, during in vertical position, the thickness of locking pin is less, can enter from the openend of connecting hole, then through the narrow first half until the lower end of connecting hole; Now, if locking pin is lateral attitude after 90-degree rotation under the effect of external force, the thickness of locking pin increases, be merely able to be stuck in lower end and can't pass from previous narrow part, the protective cover carriage and with knife plate in locking state.
As preferably, described the place ahead with knife plate top edge, connecting hole also is provided with a locating hole, this locating hole upper end open, and locating hole is arranged to by vertically being bent to gradually horizontal shape.
As preferably, described protective cover carriage bottom, with described locating hole, its position is provided with to horizontal alignment pin, alignment pin can snap in locating hole with, alignment pin orthogonal with knife plate.
Above-mentioned is another locating hole and alignment pin to cooperatively interacting.Owing to only depending on, being connected of one group of locking pin and connecting hole is very not firm, if occur rocking in the bench saw process or become flexible, very easily cause the accident, so, increased another tie point, guaranteed that the protective cover carriage is with more firm with being connected of knife plate; Only there is engagement connection between locating hole and alignment pin fast in order not affect the convenient of integrated connection simultaneously, and there is no the annexation of locking mutually.
As preferably, the front end of the protective cover of the front end of described protective cover carriage by being hinged assembly and the left and right sides forms hinge-connection.But protective cover has formed being hinged of flexible rotating with respect to the protective cover carriage, in the process of charging and the material returned, protective cover can be according to actual needs independently, rotate flexibly, all the time in optimal protective position.
As preferably, the middle part of described protective cover carriage is provided with a horizontal locating shaft, and on the protective cover panel of the described left and right sides, the position corresponding with locating shaft be provided with positioning slide, the two ends of locating shaft penetrate respectively in the positioning slide of the left and right sides.The purpose that locating shaft and positioning slide are set herein is, when protective cover rotates up and down, can control, the position of locating protective mask, especially when blade during in obliquity, protective cover also must be the inclination of equal angular, if being connected by protective cover front end and protective cover carriage only now, and there is no the constraint of locating shaft and positioning slide, protective cover can extend out towards the direction of gravity so, increases the friction while rotating, the flexibility ratio that impact is rotated.
As preferably, described positioning slide extends to the protective cover lower limb from the protective cover top edge, be provided with the laterally extending slot in both sides to the left and right in the lower end of positioning slide, and, lower end at positioning slide arranges retainer spring, retainer spring is arranged to up-narrow and down-wide shape, retainer spring opening up, and the spring on opening part both sides inside contracts and forms narrow entrance.Because the rotation of protective cover is smooth and easy very flexibly, in the process that locating shaft moves along positioning slide also almost without the friction, so, in order to meet in practical work process, sometimes need the situation that positions, avoids it arbitrarily to rotate to protective cover, lower end at positioning slide has increased retainer spring, when locating shaft slips into lower end under positioning slide, it is clamp-oned in turn, because retainer spring has elasticity, and the shape design in conjunction with up-narrow and down-wide, must be stuck in locating shaft wherein; If completed location, protective cover need to be discharged, only need use slightly large external force and just locating shaft can be pulled out in retainer spring.
In sum, the utility model compared with prior art has following advantage.
The utility model has been simplified the dismounting step of protective cover, has accelerated the dismounting speed of protective cover, has realized exempting from the singlehanded dismounting of instrument, very convenient, is conducive to increase work efficiency.
Coordinating between the locking pin that the utility model utilizes special shape and connecting hole, by the rotation lock pin, change the position relationship of locking pin and connecting hole, and, in conjunction with the elasticity of spring, finally realize that locking pin and connecting hole mutually break away from, interconnect; The connected mode that the utility model provides is simple in structure, and parts are few, and it is firm to connect; The more important thing is, the dismounting step is extremely simple, only needs one hand to fix the protective cover carriage, then stirs locking wrench with a finger, just can complete the operation of locking or dismounting.
