Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, the tightness adjusting device for a slide cable carrying cable of the present invention comprises a housing 1, as shown in fig. 2 and 3, a ratchet shaft 2 is transversely disposed in the housing 1, a connecting end of the ratchet shaft 2 is located outside the housing 1, a ratchet 3 is sleeved on the ratchet shaft 2, a rotating handle 4 is disposed at the connecting end of the ratchet shaft 2, the rotating handle 4 can rotate the ratchet shaft 2 to drive the ratchet 3 to rotate, a ratchet seat 5 is vertically disposed in the housing 1, an upper end and a lower end of the ratchet seat 5 are exposed out of the housing 1, a ratchet of the ratchet seat 5 is engaged with teeth of the ratchet 3, a pawl 6 is disposed in the housing 1, a tail end of the pawl 6 is disposed in the housing 2 through a pin 61, the pin 61 is transversely erected in the housing 1, such that the pawl can rotate in the housing 2, the improved ratchet wheel is characterized in that a reset spring 7 is arranged in the shell 1, one end of the reset spring 7 is connected with the shell 1, the other end of the reset spring 7 is connected with the lower portion of the pawl 6, the reset spring can jack the pawl, a pawl rotating control piece 8 is arranged in the shell 1, the pawl rotating control piece 8 is located above the pawl 6, and the pawl rotating control piece 8 can jack the pawl 6 to open the tooth surface of the ratchet wheel 3.

In the present invention, the upper end of the ratchet seat 5 is provided with a bearing cable long-end fixing lug 51, and the lower end of the ratchet seat 5 is provided with a bearing cable short-end fixing lug 52. The bearing cable long end fixing lug 51 is used for connecting a bearing cable at the long end of an upper station, and the bearing cable short end fixing lug 52 is used for connecting a bearing cable at the short end of a lower station, so that the tightness adjusting device can adjust the tightness of the bearing cable of the sliding cable.

In addition, for making operating personnel operate more conveniently, the cover is equipped with a handle sleeve 41 on twist grip 4.

A positioning groove (not shown) is formed in the inner wall of the housing 1, one end of the return spring 7 is arranged in the positioning groove, and the other end of the return spring 7 is connected with the lower portion of the pawl 6. The return spring can perform the return operation on the pawl.

As shown in fig. 4 and 5, the pawl rotation control member 8 of the present invention includes a rotating shaft 81, the rotating shaft 81 is transversely disposed in the housing 1, an end of the rotating shaft 81 is exposed out of the housing 1, an end of the rotating shaft 81 is provided with a direction shifting piece 82, a cam 83 is sleeved on a middle portion of the rotating shaft 81, and the cam 83 is located above the pawl 6; the direction-dialing piece 82 can drive the cam 83 to rotate on the pawl 6 after rotating, so that the pawl 6 can be clamped with teeth of the main ratchet wheel or the pawl can be separated from the teeth of the ratchet wheel. When the bearing rope needs to be loosened, the direction shifting piece can be shifted to the right, the direction shifting piece drives the cam 83 on the rotating shaft 81 to overcome the action of the return spring, namely, the cam 83 presses the pawl downwards to push the pawl to open the tooth surface of the ratchet wheel (namely, the pawl can be separated from the teeth of the ratchet wheel), and the ratchet wheel can freely rotate at the moment.
