Description

Quick bolt Technical Field The utility model belongs to the field of bolts, and particularly relates to a quick bolt. Background The bolt is widely applied to limit fixing of a plurality of objects, and has simple structure and practicality. Most of the bolts in the prior art are of columnar structures, and the bolts are inserted into the pin holes of two objects to be fixed simultaneously to realize limiting fixation in the radial direction, but the simple structure cannot realize limiting in the axial direction, so that the practicability is not strong. Disclosure of utility model The utility model aims to solve the problems in the prior art and provides a quick bolt. The aim of the utility model can be achieved by the following technical scheme: the quick bolt comprises a tubular base body, wherein a rotating column is rotationally connected to the base body, a pin tongue is arranged on the rotating column, a through hole for the pin tongue to radially extend is formed in the base body, the pin tongue is connected with an elastic structure and has a radially extending elastic trend, a retracting guide structure driven by relative rotation of the base body and the rotating column is arranged between the pin tongue and the base body, and a radially protruding limiting part is arranged on the base body. The quick bolt is used for relatively fixing two or more objects, the rotating column is inserted into the base body and is in a column shape as a whole, the quick bolt can be inserted into a pin hole of the object to be fixed, the base body is provided with the bolt which can radially and telescopically penetrate through a through hole on the base body, when the bolt extends out, a locking space is formed between the bolt and a limiting part on the base body, the object in the space can be limited and fixed in the axial direction, the limiting in the axial direction and the radial direction of the base body are realized, the retracting guide structure realizes the retracting control of the bolt through the circumferential rotation of the rotating column relative to the base body, the smooth insertion of the base body into the pin hole is ensured, and the elastic structure can enable the bolt to extend out of the through hole after the base body reversely rotates or when the rotating column is not limited, so that the smooth locking is ensured. In the above-mentioned quick bolt, the side wall of the rotary column is provided with a radially extending pin tongue groove, the pin tongue is slidably connected in the pin tongue groove, and the elastic structure is arranged between the pin tongue groove and the pin tongue. The pin tongue groove is arranged on the side wall of the rotary column, and the inner section of the pin tongue is matched with the pin tongue groove, so that the pin tongue can stably slide in the pin tongue groove. In the quick bolt, the elastic structure comprises a spring, the bottom of the bolt groove is provided with a spring groove in a radial extending mode, the spring is arranged in the spring groove, and two ends of the spring are respectively connected with the bottom of the spring groove and the bottom surface of the bolt. The bottom of the pin tongue groove is provided with a spring groove which is used for positioning the spring on the one hand and also for reserving space for the minimum length of the compressed spring on the other hand, and of course, a conical spring can be used alternatively, and the spring groove can be omitted on the bottom of the groove due to the small thickness of the compressed spring. In the above-mentioned quick plug, the retracting guide structure includes an outer guide inclined surface disposed at the front end of the latch tongue, and the outer guide inclined surface is inclined inwards in the circumferential direction. The interval of outer direction inclined plane and axial lead changes gradually in circumference direction, and when the relative rotation of steering column and base member, outer direction inclined plane cooperates with corresponding cooperation position, can make the round pin tongue inwards be pressed in the direction, realizes making the effect that the round pin tongue was retracted, of course is formed with near radially extending's face in the side that the slope top of outer direction inclined plane kept away from the slope bottom, and this face is used for spacing the reverse rotation of steering column. In the quick bolt, the outer guide inclined surface comprises a slope bottom and a slope top which are circumferentially distributed, one side of the slope bottom passing through Kong Jin is provided with an inner guide inclined surface which is inclined in the circumferential direction, the inner guide inclined surface is in sliding connection with the outer guide inclined surface, or one side of the slope bottom passing through Kong Jin is radially extended, and the outer guide inclined surface is in sliding connection w
