    • A connector of flexible pipe according to the present invention includes a flexible pipe; a fastening nut in which the flexible pipe is inserted; a latching ring having an inner portion received in a valley section of the flexible pipe and an outer portion extruded outward from a thread section of the flexible pipe for preventing the fastening nut from separating from the flexible pipe; and a socket tube screw combined with the fastening nut for pressurizing and transforming an end portion of the flexible pipe toward the latching ring. Accordingly, the coupler structure of the flexible pipe is conveniently achieved as well as the flexible pipe can be coupled easily by cutting in a desired length, and since there is no need to perform the process for machining the coupling portion, a cost for coupling the members is saved.
    • 根据本发明的柔性管的连接器包括柔性管; 一个紧固螺母,其中柔性管被插入其中; 具有容纳在柔性管的谷部中的内部部分的锁定环和从柔性管的螺纹部向外挤出的外部部分,用于防止紧固螺母与柔性管分离; 以及与紧固螺母结合的插座管螺钉,用于将柔性管的端部朝向锁定环加压和变换。 因此,柔性管的联接器结构方便地实现,并且可以通过以期望的长度切割而容易地连接柔性管,并且由于不需要执行用于加工联接部的处理,所以将 会员被保存。

    • An electric parking brake including a housing, an actuator, a gear box assembly, a driven gear, a spindle, a screw nut, an equalizer through which the spindle is penetrated and the screw nut is rotatably inserted, brake cables connected to opposite sides of the equalizer, respectively, each brake cable having a first end formed with a coupling piece for the connection of the equalizer and a second end connected to an associated one of wheel brake devices, and an emergency release device including cam units and operating levers and adapted to slacken the brake cables in an emergency release situation, so as to release the parking brake. In the case of any emergency situation, such as electric discharge of a vehicle or failure of the parking brake, the parking brake is released by a simple cable pulling action. Further, the parking brake has the effect of preventing a vehicle driver from being placed in any dangerous situation because there is no need for the vehicle driver from getting underneath the vehicle, and improving the convenience of operation because it can be released from any place where a cable is connected, such as a driver's seat, etc.
    • 一种电动驻车制动器,包括壳体,致动器,齿轮箱组件,从动齿轮,主轴,螺母,均衡器,主轴穿过该平衡器并且螺母被可旋转地插入,制动电缆连接到 均衡器,每个制动器电缆具有形成有用于连接均衡器的联接件和连接到相关联的一个车轮制动装置的第二端的第一端,以及包括凸轮单元和操作杆的应急释放装置,并且适于 在紧急情况下松开制动电缆,以释放驻车制动器。 在任何紧急情况下,例如车辆放电或驻车制动器的故障,驻车制动器通过简单的电缆牵引动作被释放。 此外,驻车制动器具有防止车辆驾驶员处于危险状态的效果,因为不需要车辆驾驶员进入车辆下方,并且提高了操作的便利性,因为它可以从任何地方 连接电缆,如司机座椅等
