Abstract
The utility model discloses an improved structure of an oblique bench pull pin. One end of a seat plate is connected on a bottom frame in a pivot mode. An arc-shaped locating piece is arranged below the bottom plate. The locating piece is provided with a plurality of locating holes. The bottom frame is provided with an inserting hole which is used for the locating piece to be inserted in. A pull pin sleeve is arranged on the hole wall of the inserting hole. The elastic pull pin is inserted inside the pull pin sleeve. The inner end of the elastic pull pin is inserted into one locating hole of the locating piece on the normal state to enable the seat plate to be fixed on the bottom frame. When the elastic pull pin is under outer force, the inner end of the elastic pull pin retreats from the locating hole so that fixation of the seat plate on the bottom frame is removed, and adjusting of the height and the inclination angle of the seat plate is achieve. According to the improved structure of the oblique bench pull pin, adjusting of the height and the inclination angle is convenient, and the oblique bench pull pin is suitable for different people and training of different intensity.
Description
Technical field
The utility model relates to the technical field of health and fitness facilities, draws the pin structure-improved relevant with oblique stool especially.
Background technology
In the prior art, the oblique stool of body-building is comprised of arch underframe, seat board and backboard; Underframe is installed on the level land, has slideway on the underframe, offers some jacks on the slideway; Slide block and locating piece are installed in the below of seat board, and slide block slidably is installed on the slideway of underframe, offers locating hole on the locating piece, draws pin to intert seat board is fixed on the underframe; Backboard is installed in an end of seat board at a certain angle, and crash roll all is housed on backboard and the seat board.
When the oblique stool of above-mentioned body-building need to be regulated height, to draw first pin to pull outward, make and draw the inner end of pin from locating hole, to withdraw from, relend and help slide block to cooperate with slideway, seat board is slided at underframe, when sliding into when being fit to the position, will draw again pin again to aim at corresponding locating hole and be inserted in the locating hole, make seat board be fixed on the underframe relevant position, finish adjusting.
This shows, the action that the height Adjustment operation of the existing oblique stool of body-building needs repeatedly plug to draw pin and aim at locating hole, Adjustment operation extremely bothers, and can only do and highly regulate and can not do the angle of inclination and regulate, and can't be fit to different crowd and varying strength and train.
In view of this, inventor's specialized designs a kind of oblique stool draw the pin structure-improved, with the adjusting at convenient height and angle of inclination, this case produces thus.
The utility model content
The purpose of this utility model provides a kind of oblique stool and draws the pin structure-improved, and the adjusting at convenient height and angle of inclination is to be fit to the training of different crowd and varying strength.
In order to reach above-mentioned purpose, solution of the present utility model is:
Tiltedly stool draws the pin structure-improved, and an end of seat board is articulated on the underframe, and the arc spacer is installed in the below of seat board, offers some locating holes on the spacer; Offer one for the interspersed jack of spacer at underframe; Draw guide to be installed on the hole wall of jack; Elasticity is drawn pin to be plugged on and is drawn in the guide; Elasticity draws pin to be inserted in the locating hole of spacer seat board is fixed on the underframe in the inner end under normal conditions, and elasticity draws pin inner end when the external broach effect to withdraw from locating hole and height and the angle of inclination of removing the fixedly realization seat board of seat board on underframe regulated.
Described elasticity draws pin by drawing pin and back-moving spring to form; Draw the inner and the outer end of guide to offer respectively inner via hole and accessibke porosity; Draw pin to be plugged on and draw in the guide, and inner via hole and accessibke porosity are passed respectively in two ends; Back-moving spring is set in and draws on the pin, and the outer end of back-moving spring is against on the peritreme of accessibke porosity and inner being against on the protruding wall that draws pin; Draw pin be inserted in the locating hole of spacer by the action of reset spring inner end in normality seat board is fixed on the underframe, draw pin inner end when being subjected to external broach, compression reseting spring to withdraw from the locating hole of spacer and remove seat board on underframe, seat board can be rotated at underframe regulate height and angle of inclination.
The jack of described underframe draws the opposite hole wall of guide that sprue is installed in installation, forms the groove that draws the inner end of pin to plant for elasticity on the sprue.
Described elasticity draws the outer end of pin that handle is installed.
After adopting such scheme, when the utility model need to be regulated the height of seat board and angle of inclination, draw pin to pull outward elasticity first, make and draw the inner end of pin from locating hole, to withdraw from, again seat board is done up and down at underframe and rotated, regulate the height of seat board and the position that the angle of inclination extremely is fit to, then decontrol elasticity and draw pin, make elasticity draw the inner end self-return of pin to be inserted on the spacer in the corresponding locating hole by elasticity, seat board is fixed on the underframe at height and angle of inclination that this is fit to, finishes height and the angle of inclination of seat board and regulate.
The utility model is compared with the latch structure that draws of the oblique stool of existing body-building, only do not need repeatedly to insert the action of drawing pin and aiming at locating hole, Adjustment operation is very convenient, and by the arc spacer with rotate the adjusting to realize simultaneously height and angle of inclination, be fit to better different crowd and varying strength and train.
