Description
Technical Field
The utility model relates to a teenager's body fitness weight lifting exercise frame body equipment especially relates to a teenager's body fitness weight lifting exercise frame whereabouts stop device.
Background
For the convenience of weight lifting practice, athletes will not generally place the weight lifting barbell directly on the ground, but rest on the cross bar of the frame body. Because the height of the body of the practicer is different, the height of the barbell placed on the cross bar needs to be adjusted at any time. The existing cross bar is of a penetrating type, namely, a cross bar penetrates through two vertical frame bodies with certain spacing to support, and a cross pin is additionally arranged at the penetrating end to prevent the cross bar from being separated.
When the height of the cross bar is changed, the cross pin at the penetrating end of the cross bar needs to be firstly pulled out, then the cross bar is pulled out from the two vertical supports separated by a certain width, and then the cross bar is transmitted into the other needed height gear hole. The mode of changing the height of the horizontal bar is relatively original and lagged, and is inconvenient to operate.
Disclosure of Invention
The utility model discloses a remedy prior art not enough, provide a teenagers' body fitness exercise frame whereabouts stop device.
In order to achieve the purpose, the utility model is realized by adopting the following technical scheme:
the utility model provides a teenagers' body fitness weight lifting exercise frame whereabouts stop device, includes that the support body supports, sleeve pipe, the sleeve pipe includes interior sleeve pipe and outer tube, be equipped with the spacer pin in the outer tube, interior sleeve pipe is on a parallel with the axis and opens there is the elongated slot, and the elongated slot is passed at the spacer pin both ends and fixes on the outer tube, and interior sleeve pipe outer end is sealed, is equipped with the pressure spring between spacer pin and the interior sleeve pipe end.
Preferably, the frame body support comprises two support rods, and a plurality of gear holes respectively corresponding to the inner sleeve and the outer sleeve are vertically distributed on the two support rods.
The diameter of the pressure spring is slightly smaller than the inner diameter of the inner sleeve, and the pressure spring is in clearance fit with the inner sleeve.
Preferably, the limit pin and the outer sleeve are of an integrated structure.
Compared with the prior art, the utility model discloses an advantage lies in with positive effect:
1. the utility model discloses simple structure, it is easy and simple to handle, shortened the adjustment time of weight lifting barbell whereabouts height.
2. The utility model discloses only need the support body to support one side opening, processing is simple and easy, and spacing altitude mixture control convenient and fast.
Drawings
Fig. 1 is a side sectional view of the present invention.
Fig. 2 is a top view (sectional view of the frame support) of the present invention.
The figures are numbered: 1. the frame body support 2, outer tube 3, inner tube 4, stop pin 5, pressure spring 6, elongated slot.
Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.
Example 1
The attached drawings are a specific embodiment of the invention, as shown in fig. 1 and fig. 2. The main part of the device comprises a frame support 1, an outer sleeve 2, an inner sleeve 3, a stop pin 4, a pressure spring 5 and the like.
The inner sleeve 3 is sleeved at one end of the outer sleeve 2, the tail end of the inner sleeve 3 is closed, and a pressure spring 5 is arranged in the inner sleeve 3. The upper end and the lower end of the inner sleeve 3 are correspondingly provided with elongated slots 6, the stop pin 4 is fixed on the inner wall of the outer sleeve 2 (can be of an integrated structure or fixed by welding and the like), and the stop pin 4 penetrates through the upper elongated slot 6 and the lower elongated slot 6 of the inner sleeve 3 and can move axially along the elongated slots 6 along with the outer sleeve 2. The compression spring 5 is positioned between the stop pin 4 and the closed tail end of the inner sleeve 3, the elongated slots 6 formed on two surfaces of the inner sleeve 3 are parallel to the axis, and the stop pin 4 penetrates through the elongated slots 6 after installation. The stop pin 4 can move axially under the drive of the outer sleeve 2 and the pressure spring 5 compresses, and the moving distance is the free distance between the stop pin 4 and the long groove of the inner sleeve 3. The diameter of the pressure spring 5 is slightly smaller than that of the inner sleeve 3, so that the inner sleeve 3 is in clearance fit with the pressure spring 5 and limited by the inner sleeve 3 to generate elastic pressure parallel to the axial direction of the inner sleeve and the outer sleeve.
The inner sleeve 3 and the outer sleeve 2 at two ends of the two rack bodies corresponding to the limiting device are provided with a plurality of gear holes with different heights, the rack body gear hole at the side of the outer sleeve 2 is large, and the gear hole at the side of the inner sleeve 3 is small, so that the inner sleeve and the outer sleeve at two ends of the limiting device are respectively inserted into the gear holes supported by the two rack bodies in a normal state.
When the required barbell falling limit height needs to be changed: 1. the outer sleeve 2 is held by hand to apply force to one side of the inner sleeve 3 axially, the inner sleeve and the outer sleeve are displaced relatively after the stop pin 4 on the outer sleeve 2 compresses the pressure spring 5, the limiting device is shortened integrally, one end of the outer sleeve 2 is separated from the restriction of the support hole, and then the other end of the limiting device can be drawn out; 2. one end of the inner sleeve 3 is inserted into a corresponding supporting hole with required height, then the outer sleeve 2 is forced to compress the pressure spring 5 towards one side of the inner sleeve 3 to integrally shorten the limiting device, and at the moment, one end of the outer sleeve 2 can be inserted into the corresponding supporting hole to complete height conversion.
The utility model discloses only need the support body to support one side opening, processing is simple and easy, and spacing altitude mixture control convenient and fast.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
