从现有两份对比文件中可以看出，现有安全注射针均采用侧向安全护套结构，安全护套内设置有与注射针针管配合的钩体，利用钩体与针管的咬合来实现安全护套与针管的相对固定，针管被隐藏在安全护套内，最终实现注射针的安全防护，有效避免意外刺伤事故。
在临床使用过程中，现有技术所记载的安全注射针在使用过程中仍然存在诸多问题，1、安全护套扣入的时候，必须要用较大的力，临床大批量使用时医护人员操作困难；2、钩体结构与针管之间的卡合存在一定的缺陷，当受到一定程度的外力时，两者容易发生脱离，稳定性和安全性均不甚理想；3、当安全护套与针管卡合后，针管仍然保持在笔直的状态，钩体与针管之间的咬合强度不大，针管在钩体内还有活动的余地，导致针管锁定结构稳定性差；4、为了实现使用后方便的将针尖扣锁在安全保护套内，很多专利另外增加了扣锁的部件或者将普通注射针针座改大，因为一次性产品的使用量非常大，造成塑料浪费、增加生产成本。
发明内容
本发明的目的在于提供一种安全注射针，其在针座侧壁上设置卡勾部件并且与安全保护套内的反向具有弹性根部卡扣部件相配合，该设计结构使得安全保护套在被扣入时弹性根部弹开扣入，手感非常轻松，经过测试计算，所需推力约为0.5N左右，临床使用时可以单手操作非常舒适；扣入后如果要打开安全保护套，卡扣的弹性根部随着针座卡勾部件作用力的方向倾斜，产生很强的抗拉力，很难打开安全保护套，克服了现有技术中存在的缺点和不足。利用普通针座的设计，最少程度增加用于实现安全功能的部件，减少产品体积，让产品成本更低更环保。
为了实现上述目的，本发明的技术方案为：一种安全注射针，它包括注射针，所述注射针由针座和针管构成，所述针座通过一弹性翻折机构与安全保护套连接，针座的侧壁上设有两个对称分布的针座卡勾，所述安全保护套，安全 保护套整体呈长条状结构，安全保护套的内腔呈中空状，安全保护套的下端与上述弹性翻折机构的一端连接，弹性翻折机构的另一端与针座的侧壁固定连接，安全保护套的上端呈悬空状，安全保护套随弹性翻折机构的翻折而翻转，安全保护套靠近上述针管的一侧形成开口，安全保护套处与开口相对的另一侧呈形成一封闭面，安全保护套中空的内腔中设有两个对称分布的具有弹性根部的护套卡扣，所述的两个护套卡扣与上述两个针座卡勾相配合，护套卡扣的外侧均设有一护套卡扣挡块。
本发明公开了一种安全注射针，其采用设置于针座侧壁的双针座卡勾结构，配合设置于安全保护套内腔的双护套卡扣，护套卡扣与针座卡勾卡合过程轻巧便捷，所需推力只需要0.5N左右，可实现单手操作，护套卡扣的外侧还设置了护套卡扣挡块，能有效防止护套卡扣与针座卡勾发生松脱。本专利技术的针座部分仍然沿用了现有常规针座的设计结构，仅仅增设了针座卡勾，该结构可一次成型，不需要为了实现安全卡扣功能而增加针座的体积或增加一个可以卡住安全帽的其它组件，有效控制成本、节省材料、简单而且有效的实现了产品的安全操作，另外，沿用常规针座的另一个好处在于，针座的位置更小，产品装配时，一条工装一次可以装配更多产品，生产效率也更高。产品整体设计用简洁的结构巧妙的实现了各项功能要求，稳定性和安全性均可达到理想效果。

具体实施方式
下面参照附图，对本发明进一步进行描述。
本发明公开了一种安全注射针，如图1和图2所示，它包括注射针1，所述注射针1由针座101和针管102构成，其区别于现有技术在于：所述针座101通过一弹性翻折机构4与安全保护套2连接，针座101的侧壁上设有两个对称分布的针座卡勾103，所述安全保护套2整体呈长条状结构，安全保护套2的内腔呈中空状，安全保护套2的下端与上述弹性翻折机构4的一端连接，弹性翻折机构4的另一端与针座101的侧壁固定连接，安全保护套2的上端呈悬空状，安全保护套2随弹性翻折机构4的翻折而翻转，安全保护套2靠近上述针管102的一侧形成开口201，安全保护套2处与开口201相对的另一侧呈形成 一封闭面202，安全保护套2中空的内腔中设有两个对称分布的护套卡扣203，卡扣203具有可以弹动的根部2031(不需要使用其他材料，只需要将该部位做到一定薄度，和安全保护套一次注塑成型)，所述的两个护套卡扣203与上述两个针座卡勾103相配合，护套卡扣203的外侧均设有一护套卡扣挡块204。
在具体实施时，所述针座卡勾103的上端部形成向一侧折弯的勾端1031，护套卡扣203由具有弹性的根部2031和卡扣端部2030构成，护套卡扣203的卡扣端部2030形成一向封闭面202的折弯，针座卡勾103与护套卡扣203的初始接触点为勾端的折弯处和卡扣端部2030的折弯处，并且，勾端与卡扣端部2030的折弯方向相反。该结构设计能确保针座卡勾103与护套卡扣203的初始接触时，两者的触摸面是两个圆弧的折弯面，或者其中一个是圆弧的折弯面，目的是将触发两者咬合的推力降到最低。同时护套卡扣203具有弹性根部2031，当扣安全护套时针座卡勾103顶住护套卡扣203，弹性根部2031顺着针座卡勾103顶的方向(图20的A方向)倾斜，卡勾顶部1030顶过卡扣203顶部时，护套卡扣203按照图21的方向回弹，扣入针座卡勾103，该扣入的力通过实验证实只需要0.5N左右。该技术特性是目前市场上同类产品所无法实现的。(局部放大见图19-图21)
当用外力想要将安全护套和针座打开时，卡勾103以图22的方向拉动卡扣203，卡扣203的弹性根部顺势向C的方向倾斜，这个时候安全护套和针座的打开力变成了：1、卡扣203头部变形滑脱的力，我们可以加厚卡勾203头部的塑料变的很难变形；2、变成拉断弹性根部2031的力，想要拉断塑料是非常困难的；3、卡勾103头部变形滑脱，但是卡勾103的一边是固定在针座上的，不会变形。综上所述所以打开力是很大的。
在具体实施时，所述勾端1031与卡扣端部2030咬合时，护套卡扣挡块204将护套卡扣203的端部限定于安全保护套2边沿和针座之间，使得护套卡扣203的端部不能左右偏离，防止护套卡扣203从针座卡勾103的两侧滑脱，并且， 护套卡扣203与两侧的护套卡扣挡块204配合对针座卡勾103形成一连续的阻挡结构。从上述结构可以看出，当勾端与卡扣端通过反向结构咬合后，通过外力还是有可能将两者分开的，理由是，护套卡扣203可以从针座卡勾103的两侧滑脱，但当护套卡扣203的两侧被护套卡扣挡块204所阻挡后，这种可能性就接近于零。
在具体实施时，所述弹性翻折机构4由固定连接板401和直角连接板402构成，固定连接板401与针座101侧壁垂直固定连接，固定连接板401的另一端与直角连接板402的一端连接，直角连接板402的另一端与安全保护套2的下端固定连接，固定连接板401与直角连接板402的连接处形成折痕线403，直角连接板402沿折痕线403翻转。
在具体实施时，所述针座101上段的两侧外壁处各设有一条加强筋104，上述针座卡勾103设置于加强筋104的顶端处。
在具体实施时，所述封闭面202由上部2021和下部2022构成，上部2021和下部2022的连接处为连续的弧面2023，上部2021和下部2022之间形成小于178度并大于120度的内夹角。该设计结构能确保在咬合状态下针管受压弯曲，并对封闭面202内壁形成反向作用力，增加牢固系数。同时，该设计结构还能最大程度的减少产品体积，利于包装和运输。
在具体实施时，所述安全保护套2中空的内腔中设有一针管固定钩205，该针管固定钩205与上述针管102相配合。
在具体操作过程中，如图3中所示，当注射完成后，将安全保护套沿着着力点A的方向下压时，带动护套卡扣往下呈弧形轨迹位移，当护套卡扣触及针座卡勾时，护套卡扣会被阻挡，经支点3向后变形，形成储蓄力B，如图4中所示，继续下压，当护套卡扣的顶点超过针座卡勾的顶点时，护套卡扣在储蓄力B的释放下形成方向力C，在其作用下抱住针座卡勾，相互咬合，完成两者的挂钩动作。如图4中所示，上述整个过程为安全保护套与注射针卡合的动作 步骤，因为护套卡扣受力变形完成挂钩，受力变形力的大小关系到操作手感，因为护套卡扣的变形部位很薄，经过测试计算，力值非常小，约0.5N，操作手感非常轻微，临床使用非常舒适。
在具体操作过程中，如图5和图6中所示，将安全保护套沿着力D的方向拉动时，带动护套卡扣沿着力E方向拉伸，会造成两个护套卡扣向两侧边发生移动，带来脱钩的风险，故本技术方案中增设了护套卡扣挡块，用于阻挡护套卡扣，故护套卡扣只承受力E，不影响护套卡扣与针座卡勾的咬合状态，故在实际使用过程中，完全杜绝了脱钩的问题，达到强化安全的目的。本产品的安全性能的考量在于卡扣与卡钩脱开失效的力值大小，护套卡扣与针座卡勾之间的咬合为倒钩式咬合，稳定性极佳，非常牢固，唯一失效的可能仅在于卡扣与卡勾变形或断裂，经测试计算，并考虑到材料本身的特性，变形脱开力值需要达到15N以上(不考虑针管脱开的力值)，由此，可见产品本身的安全系数和稳定系数均达到预期的效果值。
在本发明第一实施例中，如图7-图12所示，所述注射针1与采血管5连接。
在本发明第二实施例中，如图13-图18所示，所述注射针1与胰岛素笔6连接。
在具体实施时，所述针座卡勾103在加强筋104上端通过热变形成形。其特点是，模具结构简单，出模率高，热变形在产品组装时候完成。
在具体实施时，所述针座卡勾103在加强筋104上端通过哈弗模具成形。其特点是，可以一次注塑加工成型。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明具体实施只局限于上述这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
