拉杆是机械制造、车辆运输等领域的常用构件。拉杆应用的很多场合都是固定的，无需调节拉力。然而，在某些特殊场合，要求拉杆的拉力可调节或固定，这时普通拉杆将不能满足使用要求。 Tie rods are common components in machinery manufacturing, vehicle transportation and other fields. Many occasions where the tie rod is applied are fixed, and there is no need to adjust the tension. However, in some special occasions, the pulling force of the pull rod is required to be adjustable or fixed, and at this time, the ordinary pull rod will not meet the requirements for use.
发明内容 Contents of the invention
本实用新型的目的在于克服上述不足，提供一种拉力可调节的定力拉杆，其结构简单、操作方便、造价低廉，可满足要求拉杆拉力可调节或固定的使用场合。 The purpose of this utility model is to overcome the above-mentioned shortcomings, and provide a fixed-force pull rod with adjustable pulling force, which has simple structure, convenient operation, and low cost, and can meet the requirements of adjustable or fixed pulling force of the pull rod.
本实用新型的目的是这样实现的：一种拉力可调节的定力拉杆，它包括前段杆体、前段螺纹封头、套筒、中段螺纹封头、中段杆体、花篮螺丝和尾段杆体，所述前段杆体和中段杆体的一端通过弹簧连接，所述中段杆体的另一端插入花篮螺丝的一端，通过中段外六角螺母旋合锁紧，所述尾段杆体的一端插入花篮螺丝，通过外六角螺母旋合锁紧，在所述前段杆体和中段杆体上分别通过销轴设置有前段螺纹封头和中段螺纹封头，所述套筒设置于前段螺纹封头和中段螺纹封头之间。 The purpose of this utility model is achieved in this way: a pull rod with adjustable tension, which includes a front rod body, a front threaded head, a sleeve, a middle threaded head, a middle rod body, a turnbuckle screw and a tail rod body. One end of the front rod body and the middle rod body are connected by a spring, the other end of the middle rod body is inserted into one end of the turnbuckle screw, and screwed and locked by the middle outer hex nut, and one end of the tail rod body is inserted into the turnbuckle screw, and screwed by the outer hex nut. The front section of the rod body and the middle section of the rod body are respectively provided with a front section of the threaded head and a middle section of the threaded head through pin shafts, and the sleeve is arranged between the front section of the threaded head and the middle section of the threaded head.
与现有技术相比，本实用新型的有益效果是： Compared with the prior art, the beneficial effects of the utility model are:
本实用新型的中段杆体与尾段杆体螺纹分别为左旋和右旋，当沿一个方向转动花篮螺丝时，中段杆体与尾段杆体同时收回或放出，当定力拉杆两端固定后，旋转花篮螺丝，即可调节弹簧的拉伸量，即调节定力拉杆的拉力；花篮螺丝与中段杆体、尾段杆体之间的连接螺纹采用自锁螺纹，当定力拉杆拉力调节完成，即花篮螺丝位置固定后，将外六角螺母向花篮螺丝方向旋紧，使花篮螺丝与中段杆体、后段杆体之间产生足够的预紧力，使花篮螺丝位置固定，即保证定力拉杆的拉力恒定；将弹簧安装于套筒之内，对弹簧起到保护作用，防止弹簧损坏导致的拉杆定力不准。 The threads of the middle rod body and the tail rod body of the utility model are left-handed and right-handed respectively. When the turnbuckle screw is turned in one direction, the middle rod body and the tail-section rod body are retracted or released at the same time. , you can adjust the stretching amount of the spring, that is, adjust the tension of the fixed force rod; the connecting thread between the turnbuckle and the middle rod body and the tail rod body adopts self-locking thread, when the tension of the fixed force rod is adjusted, the position of the turnbuckle screw is fixed Finally, tighten the outer hexagonal nut toward the turnbuckle screw, so that sufficient pre-tightening force is generated between the turnbuckle screw, the middle rod body, and the rear rod body, so that the position of the turnbuckle screw is fixed, that is, the pulling force of the constant force pull rod is guaranteed to be constant; install the spring Inside the sleeve, it protects the spring and prevents the pull rod from being inaccurate due to damage to the spring.
