Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses a novel parallel bars for body-building, which is a body-building apparatus and is an improvement of the existing parallel bars for body-building.
The parallel bars comprise two groups of parallel bars with the same structure, and the two groups of parallel bars are arranged at intervals. The structure according to one of the horizontal bars is described below. As shown in fig. 1, 2 and 3, the horizontal bar includes two support columns arranged in parallel and at intervals and a transverse connecting rod 1 arranged at the top ends of the support columns. And two ends of the transverse connecting rod 1 are respectively connected with two ends of the two supporting columns.
The support column mainly comprises a fixed support column 2 and an adjusting column. The lower extreme of fixed stay post 2 and ground fixed connection, the upper end sets up the screw hole. The lower end of the adjusting column is a stud 3, and the upper end is an integrated plug-in mounting sleeve 4. The stud 3 can be in threaded fit with a screw hole in the upper end of the fixed support column 2. The upper end surface of the inserting sleeve 4 is provided with an inserting hole, and an ejector rod 5 is inserted in the inserting hole. The top end of the ejector rod 5 is used for being connected with the transverse connecting rod 1. Because the inserting sleeve 4 and the ejector rod 5 are in an inserting structure, in order to ensure the stable and reliable connection, a puller bolt 6 is arranged on the outer wall of the inserting sleeve 4 through threaded connection, and the puller bolt 6 can penetrate through the side wall of the inserting sleeve 4 to jack the ejector rod 5, so that the ejector rod 5 is prevented from moving; mainly to prevent the jack 5 from moving upwards. Since the ram 5 is less likely to move upward and is subjected to a limited amount of tension even when moved, the use of the jack bolt 6 can be satisfactory.
The carrier rod 5 is intended to be connected to the end of the transverse bar 1, where a fixed connection is not used, but rather a hinged connection. The concrete structure is that, the fixed articulated ear seat 7 that sets up in the up end of ejector pin 5, the tip of horizontal connecting rod 1 is provided with radial through-hole, and the tip of horizontal connecting rod 1 can be connected with articulated ear seat 7 through the round pin axle is articulated, and horizontal connecting rod 1 can rotate around the round pin axle. The horizontal connecting rod 1 does not move up and down when being in a horizontal state. The transverse connecting rod 1 is not directly placed on the upper end face of the ejector rod 5, but a gap must be provided between the lower side face of the transverse connecting rod 1 and the upper end face of the ejector rod 5, and the gap is controlled to be 4 cm-7 cm. The gap provides an action space for the up-and-down movement of the push rod 5, and the push rod 5 can move a certain distance along the axial direction due to the existence of the gap. When the height of the transverse connecting rod 1 is adjusted, for example, when the height needs to be adjusted, the adjusting columns at one ends are adjusted to ascend to be incapable of moving, then the adjusting columns at the other ends are adjusted to ascend to be incapable of moving, the adjusting columns on the two supporting columns need to be adjusted and rotated alternately until the preset height is reached, and the transverse connecting rod 1 needs to be ensured to be in a horizontal state. In actual tests, the requirements can be met by alternately adjusting twice or three times.
In a specific implementation, in order to facilitate the fixing of the hinge lug 7, a circular truncated cone 8 may be provided at the upper end of the push rod 5 to enlarge the area of the top end. The hinged lug seat 7 is fixedly arranged on the circular truncated cone 8, and a gap is formed between the transverse connecting rod 1 and the upper end face of the circular truncated cone 8.
In a specific implementation, the length of the threaded hole at the upper end of the fixed support column 2 is equal to or greater than that of the stud 3, so that a larger adjusting space of the stud 3 is ensured. Preferably, the stud 3 has a length of 40cm to 60 cm.
In a specific implementation, the lower end of the fixed supporting column 2 is integrally provided with a round mounting seat 9, and the round mounting seat 9 is fixedly connected with the ground by using an anchor bolt. A concrete foundation may be generally provided on the ground in advance.
The utility model is improved by arranging a height adjusting structure and adopting a sectional structure of a fixed supporting column and an adjusting column; the lower end of the adjusting column is in threaded connection with the fixed support column, and the upper end of the adjusting column is in inserted fastening connection with the ejector rod. The structure can provide stable upward axial supporting force for the transverse connecting rod, and meanwhile, the transverse connecting rod and the ejector rod can not move upwards. The utility model discloses a structure in ejector pin and the articulated of horizontal connecting rod are connected and set up the clearance can realize carrying out unilateral adjustment height in proper order to even only have the height control to horizontal connecting rod that also can accomplish alone. The novel parallel bars are good in service performance.
