Abstract

本实用新型涉及一种使用更安全可靠的气动扣 钉枪;它包括有壳体17和进气管1、启动阀和带活塞 总成10的气缸9,其主要特征是在启动闭上增设有 一带受传感器控制的安全阀的泻压孔24;使用时需 打开启动阀和安全阀,才能将气缸前端的气体经泻压 孔泻出,气缸内前后部形成压差推动活塞总成向前, 才能使扣钉顶杆撞击扣钉,使扣钉射出;本实用新型 避免了一般扣钉枪仅因启动阀被无意错打开而泻压, 扣钉误射的不足,因而使用更安全可靠。

Description

本实用新型涉及一种气动工具,特别是一种使用更安全可靠的气动扣钉枪。
现有的气动扣钉枪一般包括有枪壳体和壳体上的进气管,进气管与启动阀接通,气体经进气管、启动阀和导气管进入有活塞总成的气缸内,使气缸内活塞前后的压力形成平衡;使用时,气缸前部的气体通过管路回到启动阀腔内泻出,使气缸后部的压力大于气缸前部的压力,推动活塞带动顶杆撞击扣钉尾部,使扣钉射出;由于启动阀门的阀芯常因无意的轻微触动或抖动而打开,造成扣钉误射、乱射,因而使用极不安全可靠,如在CN2086190U中公开的自动进钉高效气动打钉机就存在上述不足。
本实用新型的目的就是设计一种结构简单,使用方便、可靠的安全气动扣钉枪。
本实用新型的目的是通过以下结构实现的:安全气动扣钉枪包括有壳体和进气管以及导气管接通的启动阀,导气管接在有活塞总成、活塞平衡阀的气缸上,气缸前端固有有导钉板的钉夹总成,其主要特征在于:启动阀是由带有进气孔、进出气孔和泻压孔的阀体以及在泻压孔与进气孔之间的隔片组成,隔片单向滑动套有顶开进气孔的阀芯,在泻压孔上接有受传感器控制的安全阀;使用时,在启动阀打开的同时必须触发传感器打开安全阀,使气缸前端的气体经启动阀的泻压孔顺利泻出,才能使气缸前后两部形成气压差,活塞总成才能带动顶杆撞击扣钉;如安全阀关闭,即使启动阀被误打开气体也不能泻出,则活塞总成不能动作,扣钉就不会误射。
本实用新型与现有技术相比,由于仅在启动阀上增设泻压孔和隔片以及传感器、安全阀,因而结构简单,且在使用上避免了扣钉枪误射,具有使用安全可靠等优点。
本实用新型的附图说明如下:
图1为本实用新型的结构示意图;
图2为图1的A-A向剖视图;
图3为启动阀结构示意图;
图4为安全阀示意图;
图中:1、进气阀,2、启动阀推杆,3、阀芯,4、阀体,5、导气管,6、弹簧,7、活塞平衡阀,8、紧圈,9、气缸,10、活塞总成,11、顶杆,12、弹簧,13、阀座,14、阀杆,15、弹簧,16、板柄,17、壳体,18、钉夹总成,19、曲杆,20、摆动压板,21、导钉板,22、进气孔,23、进出气孔,24、泻压孔,25、隔片。
下面结合附图和实施例对本实用新型作进一步说明。
如图1所示:本实用新型包括有壳体17和进气管1以及与导气管5接通的启动阀2,导气管接在有活塞总成10,活塞平衡阀7的气缸9上,气缸前端固有带导钉板21的钉夹总成18,其中:启动阀是由带有进气孔22,进出气孔23和泻压孔24的阀中4以及在泻压孔与进气孔之间的隔片25组成,隔片单向滑动套有顶开进气孔的阀芯3,在泻压孔上接有受传感器控制的安全阀;传感器是由滑动固在导钉板21上的安全顶杆11和与顶杆固接顶紧安全阀杆14的曲杆19构成,如图2所示,使用时只需顶动顶杆带动曲杆顶动安全阀杆则可打开安全阀,为了顶动顶杆更方便,顶杆前端略前于导钉板前端;为了使阀芯3实现单向滑动和泻压时隔片有微漏气,阀芯3的前端略大于后部,如图3所示;安全阀可由阀体、阀杆14和套在阀杆后部的弹簧12构成,如图4所示。
