Description

一种执手具有缓冲功能的门锁 技术领域
本实用新型涉及一种门锁，具体是一种执手具有缓冲功能的门锁。
背景技术
目前市场上的面板锁具在家庭和办公楼宇、医院等场合得到广泛的使用。但现有市面上使用的锁具是没有缓冲、减振、减噪音功能的，这些锁具在使用过程中会产生噪音，给正在休息的家人、正在工作的人员、正在疗养的病人带来不小的影响。究其原因，其最主要的噪声来源于拨叉与执手复位时，限位部件之间的相互撞击。现有技术中，由于执手体积大，质量重，为了使其在开锁后能自动复位，在执手与面板间设置有复位装置，当用户转动执手开锁后。随着用户施加的扭力的消失，执手在复位装置的作用下快速回弹复位，执手带动拨叉上的限位装置快速撞击，从而发出工作噪音，因此有必要对现有的锁体结构作进一步改善，以降低其工作噪音。
实用新型内容
本实用新型的目的是为了克服已有技术存在的缺点，提供一种结构简单，使用方便，能降低关门噪音，减少机械磨损，延长使用寿命的一种执手具有缓冲功能的门锁。
本实用新型目的是用以下方式实现的：一种执手具有缓冲功能的门锁，其包括锁体及铰接安装在锁体上的执手，执手内设置有方杆孔，方杆孔套装在锁芯驱动杆表面，用户转动执手通过方杆驱动锁芯运动，实现开锁及关锁，其特征在于：所述的锁体内设置有拨叉片，拨叉片套装在方杆孔表面，拨叉片随着执手转动而转动，所述的锁体内还铰接安装有驱动片，驱动片中部与锁体铰接，其一端通过连接板与拨叉片铰接，其另一端与缓冲 缸的活塞杆铰接，缓冲缸的尾端与锁体铰接，执手转动时，缓冲缸产生阻尼减缓执手回弹速度。
所述的驱动片中部设置有铰接孔，锁体内设置有铰接座与该铰接孔连接。
所述的所述的铰接座包括固定在锁体上的固定轴及套装在该固定轴表面的转动套，转动套与铰接孔固定。
所述的驱动片、连接板及缓冲缸呈半包围结构分布在方杆孔外围。
所述的缓冲缸为拉伸缓冲型液压缓冲缸。
本实用新型的有益效果是：1、结构简单可靠，生产成本低，市场竞争力强。2、在锁体内设置有缓冲缸，缓冲缸通过驱动片及连接板与执手连接，执手复位时，缓冲缸产生阻尼降低执手的回弹速度，从而避免执手回弹速度过快产生噪音。3、驱动片及连接板的设置，有效降低力臂的长度，从而令本结构更为紧凑。
附图说明
图1、2为本实用新型总装效果图。
图3为本实用新型中隐藏隔板后结构示意图。
图4为本实用新型结构装配图。
图5为本实用新型中驱动片及连接板与缓冲缸装配图。
具体实施方式
下面结合附图对本实用新型作具体进一步的说明。一种执手具有缓冲功能的门锁，其包括锁体1及铰接安装在锁体1上的执手2，执手内设置有方杆孔3，方杆孔套装在锁芯驱动杆表面，用户转动执手2通过方杆驱动锁 芯运动，实现开锁及关锁，其特征在于：所述的锁体1内设置有拨叉片4，拨叉片4套装在方杆孔表面，拨叉片4随着执手2转动而转动，所述的锁体1内还铰接安装有驱动片5，驱动片5中部与锁体1铰接，其一端通过连接板6与拨叉片4铰接，其另一端与缓冲缸7的活塞杆71铰接，缓冲缸7的尾端与锁体1铰接，执手2转动时，缓冲缸7产生阻尼减缓执手2回弹速度。
所述的驱动片5中部设置有铰接孔51，锁体1内设置有铰接座8与该铰接孔51连接。
所述的所述的铰接座8包括固定在锁体上的固定轴81及套装在该固定轴表面的转动套82，转动套82与铰接孔固定。
所述的驱动片5、连接板6及缓冲缸7呈半包围结构分布在方杆孔3外围。
所述的缓冲缸7为拉伸缓冲型液压缓冲缸。
工作原理：本案中的执手在开关过程中，驱动拨叉片运动，其中拨叉片上设置有限位缺口，并设置有限位台置于该限位缺口内，限位缺口的设置使得本执手只能旋转一定的角度，从而避免执手开合角度过大影响手感。
进一步地：如图3所示，常态下，缓冲缸处于压缩状态。当用户向下扳动执手开门时，执手带动拨叉逆时针转动，使得拨叉通过连接板驱动驱动片发生偏转，驱动板偏转时其另一端向内推动缓冲缸，使得缓冲缸向内回缩。其中由于本案中的缓冲缸为拉伸缓冲型，因此缓冲缸向内压缩时，不会产生阻尼。
当用户松手后，执手在复位弹簧的作用下反转复位，使得锁具处于关 闭状态。执手在复位过程中，拨叉片通过连接板拉动驱动板回转，此时的缓冲缸的活塞杆被缓慢拉出，执手缓慢复位关闭，从而避免了传统技术中门锁复位速度过快造成的响声及磨损，在提升使用质感的同时，避免锁具内部磨损过快影响其使用寿命。
进一步地：本案中采用驱动片及连接板中转的结构可使得缓冲器利用较小的行程即可实现对拨叉的缓冲，从而降低缓冲器的体积及运动行程，使得锁具内部结构更为紧凑小巧，工作效率也更高，故可广泛推广使用。
以上显示和描述了本实用新型的基本原理和主要特征和本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本实用新型的原理，在不脱离本实用新型精神和范围的前提下，本实用新型还会有各种变化和改进，这些变化和改进都落入要求保护的本实用新型范围内。
