Description

Bench press body-building apparatus of area protection

Technical Field

The invention relates to the technical field of fitness equipment, in particular to a protective lying-pushing fitness equipment.

Background

Along with the development of society, people begin to pay more and more attention to their health, and people also seek correct and effective fitness methods while paying more attention to their bodies. However, in the gymnasium, the recumbent push apparatus has been popular as an effective apparatus for exercising upper body muscles, but the statistical flat-plate recumbent push is one of the apparatuses with the highest global fatality rate. The currently used relatively extensive bench press mainly increases the weight at the connecting section of the bench press bar, thereby achieving the effect of weight increasing exercise.

For example, Chinese patent discloses a 'free lying push protection device' (patent number: CN201810542768.X), which comprises a support plate arranged at intervals, a plurality of hooks arranged at intervals on the front wall surface of the support plate, barbells hung on the hooks, a lying push chair arranged in front of the support plate, and the barbells are prevented from falling by using the hooks.

However, during exercise, many people add a very high weight to the barbell in pursuit of the limit, and during exercise, the barbell cannot be placed on the hook at the first time due to the fact that arms cannot bear the force of the barbell, so that hands are loosened to cause the barbell to fall.

Detailed Description

The embodiment of the invention provides a protective lying-pushing fitness apparatus, which comprises a supporting seat 1, a fixing hole 3, a holding rod 5, two box bodies 7, a sliding block 8 and two fixing columns 9 as shown in figures 1-5. The fixed orifices 3 are the equidistance and offer on supporting seat 1, and two box 7 are fixed mounting respectively in 5 both sides of holding rod, and slider 8 is in 7 both sides mirror image distributions of box, and two fixed columns 9 pass box 7 both sides dorsad respectively and set up, fixed orifices 3 and fixed column 9 phase-match. Two first support rods 11, two sliding grooves 12, a second support rod 13, a first spring 14, a second spring 15, a handrail 16 and a support plate 17 are arranged in the box body 7. The vertical fixed mounting of backup pad 17 is in bottom in box 7, and two chutes 12 are vertical to be seted up in backup pad 17 one side, two bracing piece 11 one sides respectively with two chutes 12 sliding fit, two bracing piece 11 opposite sides articulate respectively in two fixed columns 9 one sides. The handrail 16 is fixedly arranged on the surface of one end of the second support rod 13, the first spring 14 is fixedly arranged between the second support rod 13 and the box body 7, one side of the second support rod 13 is respectively pivoted with the bottoms of one sides of the first support rods 11, the other side of the second support rod 13 penetrates through the box body 7 and is arranged in the holding rod 5, and the second spring 15 is fixedly arranged between the bottoms of the second support rod 13 and the holding rod 5.

The second support rod 13 is driven by pressing down the handrail 16, the first support rod 11 is driven by the support rod 13, and the first support rod 11 slides downwards through the sliding groove 12 formed in the support plate 17, so that the fixing column 9 hinged with the first support rod 11 is driven, the fixing column 9 leaves the fixing hole 3, and the bench press training is started.

Also included are top seat 4 and notch 201. The notch 201 passes through the support seat 1. The top seat 4 is fixedly installed at the top of the supporting seat 1, sliding rails 202 are arranged on two sides in the groove opening 201, and the sliding rails 202 are in sliding fit with the sliding blocks 8.

Through the sliding fit of the sliding block 8 and the sliding rail 202, the person can only move up and down when pushing, thereby ensuring that the holding rod 5 cannot deviate in position during movement.

When the body-building personnel exercises, the first reaction is to loosen the hands and loosen the hands when the body-building personnel encounters exhaustion, so that the main barbell can be clamped when the personnel suddenly loosens the hands through the matching of all the parts, and the safety of the personnel is protected.

The barbell bar comprises a barbell bar 6 and a baffle 10, wherein one side of the barbell bar 6 passes through the baffle 10 and is fixedly arranged on one side of the box body 7.

The working principle is as follows: when the barbell bar is used, a person firstly puts a barbell disc on the barbell bar 6, then the person lies on the deck chair, holds the position of the handrail 16 on the holding rod 5 with two hands, presses down the handrail 16, the handrail 16 drives the supporting rod two 13, the supporting rod 13 drives the supporting rod one 11, and the supporting rod one 11 slides downwards through the sliding groove 12 formed in the supporting plate 17, so that the fixing column 9 hinged with the supporting rod one 11 is driven, the fixing column 9 leaves the fixing hole 3, and the bench press exercise is started. If the two hands of the person leave the handrails 16, the first spring 14 at the bottom of the first support rod 11 bounces to drive the first support rod 11 to slide upwards, so that the fixing column 9 is ejected out to enter the fixing hole 3 to clamp the holding rod 5 and the barbell bar 6, the holding rod and the barbell bar are not easy to fall, and the person is protected from being injured.

In summary, the barbell can be fixed by the protective bench press fitness equipment through the matching of the fixing column and the fixing hole, so that the barbell is prevented from falling; through setting up the handrail on the holding rod, the handrail passes through the cooperation of bracing piece, spring and fixed column, can control the fixed column in holding rod department, when carrying out the bench press, loosens the handrail suddenly and bounces, pops out the card with the dead lever of linkage and goes into in the fixed orifices, prevents that the barbell from falling.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
