In the absence of conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other to obtain new embodiments.

[0019] In addition, it should be noted that, unless otherwise clearly specified and limited, the words "installed", "connected", "connected" and similar terms used in the description of this application should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. Technical personnel in the field can understand their specific meanings in this application according to the specific circumstances.

[0020] The main body of the columnar tensioner of the present application is composed of a sleeve mechanism, a tension rod mechanism and a force-limiting spring. The functional requirements of aircraft field mooring can be met by connecting the grommets at both ends of the tensioner. The surface of the tension rod can be marked with scale values, which can be used to accurately measure the range of tension values ​​during mooring. It meets the design requirements of the mooring function when special aircraft models are parked in the field and important components (wings are too long) are limited by the maximum preload.

[0021] like Figure 1-Figure 5 As shown, in order to solve the above problems, the present application provides a columnar tensioner, comprising:

[0022] The tension rod mechanism 2 comprises a screw rod 6 having threads at both ends, a first fixing bolt 4 connected to the first end of the screw rod 6, and a second fixing bolt 5 connected to the second end of the screw rod 6. The second end of the screw rod 6 has a screw head, and the screw head has a through hole, and a right threaded grommet 7 is inserted in the through hole;

[0023] The sleeve mechanism 1 comprises a barrel having a central passage and a left threaded grommet 8 at a first end of the barrel, wherein the outlet diameter of the central passage at a second end is smaller than the inner diameter of the central passage;

[0024] Spring 3;

[0025] The tension rod mechanism 2 is sleeved in the central channel of the sleeve mechanism 1, the spring 3 is sleeved on the tension rod mechanism 2, one end of the spring 3 is against the first fixing bolt 4, and the other end is against the inner edge of the central channel outlet, and the second fixing bolt 5 is against the outer edge of the central channel outlet under the action of the spring 3. The straight rod of the tension rod mechanism 2 has a scale.

[0026] The tension rod mechanism 2 and the sleeve mechanism 1 are connected to ropes at both ends. The rope overcomes the spring force under the tension at both ends to make the screw rod 6 extend out of the sleeve mechanism 1. The range of the tension is determined by observing the extension amount of the screw rod 6.

[0027] In some optional embodiments, the left threaded cable ring 8 includes a connecting bolt and an insert ring. The connecting bolt is threadedly connected to the barrel of the sleeve mechanism 1. The connecting bolt has a through hole, and the insert ring is inserted into the through hole.

[0028] In some optional embodiments, a gasket is provided between the first fixing bolt 4 and the spring 3 .

[0029] In some optional embodiments, a sensor is provided between the tension rod mechanism 2 and the sleeve mechanism 1. When the tension rod mechanism 2 axially escapes from the sleeve mechanism 1 by a predicted length, the sensor is switched on and issues a prompt.

[0030] The advantages of the present application include: 1. The present application converts the pulling force into the pressure of the spring. Even if the spring is damaged in the extreme state, the left threaded grommet 8 and the right threaded grommet 7 will not be disengaged, thus ensuring safety. 2. The present application can adjust the initial compression of the spring by adjusting the screwing of the second fixing bolt 5, thereby adjusting the pulling force range. 3. The present application sets scales, and color areas can be set between the scales, so that the pulling force range can be quickly checked, or the pulling force range can be quickly determined by a sensing device.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
