Technical Field

The utility model relates to a technical field of body-building auxiliary machinery, in particular to protector is used in bench press training.

Background

The bench press is a short term for supine press, also called as bench press or bench press, mainly exercises pectoralis major, pectoralis minor, deltoid anterior, brachial triceps and elbow, and also exercises premolars, biceps brachii, brachial coracoid and forearm muscle groups, and the like, and has a significant effect on developing extensor muscles of upper limbs and pectoralis major, which is incomparable with other actions, and a prescribed action of strength-lift competition, so that the demand for a safety protection device for barbell bench press training is increasing.

Barbell bench press training that exists on the existing market does not avoid the accident that appears in the training process, leads to partial training person to receive the injury when the training, consequently, provides a safety device for barbell bench press training to above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a protector is used in bench press training to solve the easy injured problem in the current barbell bench press training process.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: the utility model provides a protector is used in bench press training, includes four support columns that become the rectangular distribution, every the bottom of support column all is equipped with the chassis, two that correspond around all by supreme first telescopic link and the pivot of being connected with down between the support column, the extension rod is connected in the free end rotation of pivot, it has a plurality of through-holes to run through on the extension rod, lies in to be connected with the second telescopic link between two extension rods with one side.

The principle and the effect of the technical scheme are as follows: when people carry out barbell bench press training, place the support column in the both sides of bench press equipment, can make two elbows of training personnel open completely when interval between two extension rods can be complete through adjusting first telescopic link, and through adjusting the length of second telescopic link, can make this device be applicable to the training personnel of different heights, at last through adjusting the concrete position of second telescopic link both ends on the extension rod to ensure that training personnel do not receive the injury under different training actions, improved the security of training.

Further, every the support column is all run through to the front side of pivot, the front end that lies in the support column in the pivot by inside outside be equipped with in proper order first ratchet and with first ratchet on the second ratchet opposite direction, first ratchet is located the front and back both sides that correspond the support column respectively with the extension rod, still rotate on the support column at first ratchet place and be connected with first ratchet matched with first pawl and with second ratchet matched with second pawl, first pawl, second pawl respectively and support column between all be connected with the torsional spring, be equipped with the twist grip on the front end of pivot.

Through the aforesaid setting, can restrict the anticlockwise clockwise rotation of first ratchet with the help of first pawl, the second pawl restricts the clockwise rotation of second ratchet, thereby can fix the pivot with the help of first ratchet and second ratchet, the stability of this device has been strengthened, and when rotating the turning handle, with arbitrary pawl and the ratchet phase separation back that corresponds, can drive pivot and extension rod and rotate along a direction, thereby realize the regulation to the extension rod angle, can make the second telescopic link when adjusting self length, the both ends of second telescopic link can keep the level.

Furthermore, every the left and right sides of second telescopic link all is equipped with a plurality of draw-in grooves with barbell matched with at an interval.

Through the arrangement, the barbell can be hooked in the training process if the barbell suddenly falls off by means of the clamping groove, and the problem that the barbell falls off to a person is avoided.

Further, a rubber gasket is adhered to the bottom of the chassis.

Through the setting, can play skid-proof effect with the help of the rubber gasket to make this device can place on unclean subaerial and do not take place the slope, maintained the stability of this device.

Compared with the prior art, the beneficial effect of this scheme:

1. according to the scheme, the length of the first telescopic rod is adjusted, so that the device does not influence the bench press action of a trainer;

2. this scheme is through adjusting the height at second telescopic link both ends and realize the protection to different bench presses actions, has strengthened bench press training's security.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments:

reference numerals in the drawings of the specification include: the device comprises a support column 1, a chassis 2, a rubber gasket 3, a first telescopic rod 4, a rotating shaft 5, an extension rod 6, a second telescopic rod 7, a first ratchet wheel 8, a second ratchet wheel 9, a first pawl 10, a second pawl 11, a rotating handle 12 and a clamping groove 13.

The embodiment is substantially as shown in figures 1 and 2: the utility model provides a protector is used in bench press training, includes four support columns 1 that become the rectangle and distribute, and the bottom of every support column 1 all is equipped with circular shape chassis 2, and the bottom of every chassis 2 all is stained with rubber gasket 3, borrows rubber gasket 3 to make this device place the subaerial and the not slope of taking place of the cleanliness factor of difference, has strengthened the stability of this device, and rubber gasket 3 still can play skid-proof effect simultaneously. All pegging graft between two support columns 1 that correspond around and having first telescopic link 4 and pivot 5, the front end of every pivot 5 all runs through support column 1 and pivot 5 rotates and connects on support column 1, interval division has two pinholes on pivot 5, all peg graft in every pinhole and have extension rod 6, it has five through-holes to open on four extension rods 6 of the left and right sides, be located and be connected with second telescopic link 7 between two extension rods 6 with one side, round pin axle that blocks with the through-hole mutually is all worn to be equipped with at both ends about every second telescopic link 7, the draw-in groove 13 that three equidistance distributes is all opened to the left and right sides of every second telescopic link 7, draw-in groove 13 can cooperate with the barbell, the condition that the sudden landing of barbell and cause the injury to training personnel has been avoided.

As shown in fig. 3, one end of each rotating shaft 5, which is located outside the supporting column 1, is coated with a first ratchet wheel 8 and a second ratchet wheel 9, which is opposite to the direction of the ratchet on the first ratchet wheel 8, the first ratchet wheel 8 and the extension rod 6 are respectively located at the front side and the rear side of the corresponding supporting column 1, the supporting column 1 where the first ratchet wheel 8 is located is further rotatably connected with a first pawl 10 matched with the first ratchet wheel 8 and a second pawl 11 matched with the second ratchet wheel 9, the first pawl 10 can limit the ratchet wheel to rotate anticlockwise, the second pawl 11 can limit the ratchet wheel to rotate clockwise, torsion springs are respectively connected between the first pawl 10 and the second pawl 11 and the supporting column 1, and a rotating handle 12 is further adhered to the front end of the rotating shaft 5.
