Description

一种手动钉枪 技术领域
本实用新型属于打钉工具技术领域， 涉及一种手动钉枪， 特别是涉 及一种具有安全锁定功能的手动钉枪。 背景技术
在装修行业中， 手动钉枪得到广泛的应用。 申请人于 2009年 7月 23日 递交一件实用新型申请， 其公告号 CN201483458 , 该手动钉枪的结构是这 样的， 包括具有凹槽的枪体、 撞针、 储钉槽、 弹簧钢片和压板手， 所述 的撞针设置在枪体的凹槽内， 储钉槽与枪体的凹槽相联通， 压板手一端 作用在撞针上， 另一端穿出枪体， 且压板手能带动撞针沿着凹槽移动， 弹簧钢片一端作用在撞针上， 另一端作用在枪体上， 枪体内还设有当撞 针远离储钉槽时能将撞针锁定住的控制机构。
它的主要工作原理如下， 钉子整排的放置在储钉槽内， 由于储钉槽 是与枪体的凹槽相联通的， 储钉槽最顶部的钉子被输送到枪体的凹槽中。 扳动压板手， 压板手带动撞针沿着凹槽远离储钉槽。 在撞针移动的过程 中， 作用在撞针上的弹簧钢片产生一个弹力； 压板手在扳动到一定程度 后， 压板手脱离撞针， 在弹簧钢片的弹力的作用下， 撞针将储钉槽最上 端的钉子打出去。 在枪体内增加了当撞针远离储钉槽时能将撞针锁定住 的控制机构， 这样在需要时就可以先扳动压板手， 使控制机构将撞针锁 定住， 然后只要轻轻扳动控制机构就可以实现将储钉槽最顶部的钉子打 到需要的地方去。
其控制机构包括开设在撞针上的通孔、 设置枪体内的锁针、 锁针管、 扭簧和小扳手， 锁针一端穿过锁针管与通孔相连， 另一端与小扳手相连， 扭黄一端作用在锁针上， 另一端作用在枪体上。
该手动钉枪虽然考虑了钉枪使用的安全问题， 采用控制机构来控制 撞针， 只在需要时通过扳动小扳手来进行打钉， 从而达到省力和安全的 目的， 但是该手动钉枪却没有解决在枪口正对附近人员时意外触动压板 手或者小扳手从而导致将附近人员打伤的情况， 特别是触动小扳手造成 钉子意外打出的情况， 因为小扳手所需的扳动力比压板手小很多。 发明内容
本实用新型针对现有的技术存在上述问题， 提出了一种手动钉枪， 该手动钉枪具有较高的安全性， 能防止钉子意外打出， 并且使用方便。
本实用新型通过下列技术方案来实现： 一种手动钉枪， 包括枪体和 设置在枪体内能往复移动的撞针， 其特征在于， 在枪体内设有为撞针提 供打钉动力的复位弹簧， 在枪体上设有使上述复位弹簧变形积蓄弹力并 传递弹力到撞针上使撞针打出的手柄， 在枪体内设有使复位弹簧锁定变 形状态用来阻挡撞针打出的锁定机构， 在枪口处设有能够往复移动的解 锁件， 所述解锁件的一端抵靠在锁定机构上并在锁定机构的作用下所述 解锁件的另一端伸出枪口外， 在解锁件往枪口内移动时所述解锁件带动 锁定机构解除对复位弹簧的锁定。
本手动钉枪通过设置在枪口处的解锁件对枪体内的锁定机构进行解 锁， 由于解锁件设置在枪口处， 而钉枪打钉时需要靠近墙体等固定面， 因此， 一端伸出枪口外的解锁件就通过墙体等固定面的推压使解锁件往 枪口内移动， 这时解锁件才带动锁定机构解除对复位弹簧的锁定。 通过 这种结构能够保证使用者在使用本钉枪时必须对着墙体等固定面推压才 可以打出， 即本钉枪的枪口没有对着墙面等固定面挤压， 即使按下手柄 也不会打出钉子， 防止钉子意外打出的情况， 提高了钉枪使用的安全性。
作为手柄和撞针的第一种方案， 在上述的手动钉枪中， 所述撞针上 连接有滑块， 所述滑块与上述复位弹簧连接并将滑块设置在复位弹簧变 形的方向上， 所述手柄能够连接和脱离滑块， 在手柄连接上述滑块时能 带动滑块使复位弹簧变形， 上述的锁定机构能够连接到滑块上使滑块保 持复位弹簧处于变形状态， 并在锁定机构连接到滑块上时所述的手柄脱 离所述的滑块。 手柄带动滑块移动， 通过滑块使复位弹簧产生变形积蓄 弹力， 在滑块移动一段距离后锁定机构连接到滑块上用来阻挡滑块在弹 力作用下反向移动。 而在锁定机构连接到滑块上时所述的手柄脱离所述 的滑块， 这时只要通过上述解锁件对锁定结构进行解锁， 滑块和连接在 滑块上的撞针就处于自由状态， 在复位弹簧的弹力下， 将通过滑块将撞 针打出。
在手柄和撞针的第一种方案中， 在上述的手动钉枪中， 所述的锁定 机构包括锁定件和带动锁定件阻挡在滑块移动路径上的传动结构， 上述 的解锁件与传动结构相抵靠， 在传动结构上连接有带动传动结构使锁定 件移动到滑块移动路径上和同时使上述解锁件伸出枪口的锁定弹簧。 在 锁定弹簧的作用下， 传动结构带动锁定件移动到滑块的移动路径上， 同 时传动结构也推动解锁件往枪口外移动， 在打钉时， 解锁件往枪口内移 动时推动传动结构反向移动克服锁定弹簧的作用力从而由传动结构带动 锁定件脱离滑块， 此时滑块才处于自由状态。
除了上述这种锁定机构外， 锁定机构还可以采用直接插接在滑块内 的锁定插件以及相类似结构配合相应的传动结构来实现； 或者锁定机构 采用拉住滑块的锁定绳索以及相类似结构配合相应的传动结构来实现。

以下是本实用新型的具体实施例， 并结合附图对本实用新型的技术 方案作进一歩的描述， 但本实用新型并不限于这些实施例。
实施例 1 :
如图 1和图 2所示， 手柄钉枪包括枪体 1、 设置在枪体 1 内的储钉 槽 2和在枪体 1 内能往复移动的撞针 3， 枪体 1为正常的手枪形状， 枪 体 1的枪膛部分设置安装槽， 撞针 3设置在安装槽 1 1内， 储钉槽 2与安 装槽 11相连通， 撞针 3经过储钉槽 2 的出钉口， 撞针 3撞击储钉槽 2 出钉口上的钉子时能将钉子打出。
在枪体 1 内设有为撞针 3提供打钉动力的复位弹簧 4， 在安装槽 1 1 内还安装有滑块 5， 撞针 3连接滑块 5， 滑块 5与复位弹簧 4连接并将滑 块 5设置在复位弹簧 4变形的方向上， 在枪体 1上设有使复位弹簧 4变 形积蓄弹力并传递弹力到撞针 3上使撞针 3打出的手柄 6， 手柄 6能够 连接和脱离滑块 5， 在手柄 6连接滑块 5时能带动滑块 5使复位弹簧 4 变形， 锁定机构能够连接到滑块 5上使滑块 5保持复位弹簧 4处于变形 状态， 并在锁定机构连接到滑块 5上时手柄 6脱离滑块 5。 具体来说， 如图 5所示， 该滑块 5为实心的条形金属块， 撞针 3通 过滑块 5上的定位柱 5 1连接到滑块 5上， 滑块 5两侧具有突出的边沿 52， 该边沿 52与安装槽 1 1配合使滑块 5只能在安装槽 1 1 内滑动。滑块 5 的一端具有安装孔， 复位弹簧 4为条形螺旋弹簧， 复位弹簧 4沿着滑 块 5移动方向设置， 复位弹簧 4的一端安装于安装孔内并作用在滑块 5 上， 另一端作用在能够调节弹簧弹力的调整结构上。 配合图 1、 图 3和 图 5所示， 调整结构包括固定在枪体 1上的座体 7和与座体 7通过螺纹 连接的调节螺栓 8，在调节螺栓 8上开有放置复位弹簧 4端部的座孔 81。 通过调节螺栓 8的前进和后退来实现复位弹簧 4的弹力调节。 采用条形 螺旋弹簧和配合实心金属滑块的重量能够完全代替现有产品中的条形弹 片， 并且还能实现对弹簧弹力的调节， 能够延长产品的使用寿命和适应 多种打钉输出力的需求。
如图 1和图 3配合图 2、 4、 5所示， 手柄 6上设有条形销孔 61， 在 条形销孔 6 1内设有销轴 9并且该销轴 9固定在枪体 1内，在手柄 6外侧 还有一卡位口 64并在卡位口 64内设置定位销 2 1， 该定位销 2 1 固定在 枪体 1内， 销轴 9上套有一端作用在手柄下端 62和另一端作用在枪体 1 内壁上的扭簧 10。 正常状态下手柄 6如图 5所示， 销轴 9位于条形销孔 61的下方阻挡手柄 6， 且手柄上端 63伸入到滑块 5内， 转动手柄 6， 手 柄 6移动到定位销 2 1并绕定位销 2 1转动直到销轴 9阻挡在手柄的条形 销孔 6 1上方阻止手柄 6继续移动， 在手柄 6移动过程中手柄上端 63会 下移而脱离滑块 5。
在滑块底面 53开设有凹槽 54， 手柄上端 63插接在凹槽 54内时带 动滑块 5移动， 在手柄上端 63脱离滑块 5时即手柄上端 63脱离凹槽 54 时， 在滑块 5和手柄上端 63之间设有阻挡手柄 6复位的反复位结构。反 复位结构包括设置滑块 5上的挡板 55和设置在手柄上端 63的反复位弹 簧 1 1， 在手柄上端 63脱离滑块 5 时反复位弹簧 1 1一端作用在挡板 55 上， 另一端作用手柄上端 63来阻止手柄 6复位。 为保证结构稳定， 在反 复位弹簧 1 1 内设有螺栓 12， 该螺栓 12的螺纹段穿过手柄上端 63的通 孔后与一螺母 13连接， 反复位弹簧 11的一端顶压在手柄上端 63上， 另 一端顶压在螺栓 12的螺栓头上，手柄上端 63脱离凹槽 54时螺栓头顶压 在滑块 5的挡板 55上。反复位弹簧 11的弹力大于扭簧 10的弹力，因此， 在滑块 5移动前， 手柄上端 63不会在扭簧 10的作用力下提前插接到凹 槽 54中。 只有在滑块 5复位后才手柄 6才能在扭簧 10的作用力复位。
锁定机构用来使复位弹簧 4锁定变形状态以阻挡撞针 3打出， 在枪 口处设有能够往复移动的解锁件 14， 解锁件 14 的一端抵靠在锁定机构 上并在锁定机构的作用下解锁件 14 的另一端伸出枪口外， 在解锁件 14 往枪口内移动时解锁件 14带动锁定机构解除对复位弹簧 4的锁定。

为在打钉时保证枪口正对墙壁等固定面时才能打出， 保证钉子打出 时是垂直于墙面的， 解锁件 14由条形片状体弯折形成 L形， 较长的一边 为长片体 141， 较短的一边为短片体 142， 长片体 141插接在枪口内与上 述的竖挡片 172接触， 短片体 142覆盖在枪口上并在短边上开设供撞针 3穿出并与枪口相适应的通孔 1421。
本手动钉枪有两种操作方式： 第一种是先将解锁件 14 按压在墙面 上， 解锁件 14对锁定机构进行解锁， 然后通过手柄 6实现打钉； 第二种 是先按压手柄 6， 然后将解锁件 14按压在墙面上， 解锁件 14对锁定机 构进行解锁， 钉枪打出一次钉子。 不管何种方式， 都需要将解锁件 14 按压在墙面上才能将钉子打出， 用于提高钉枪使用的安全性， 防止对附 近人员的伤害。 实施例 2 :
