Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to double dumbbell bench press equipment with a ground protection function. Background Art

[0002] The dumbbell bench press is a machine exercise. The bodybuilder holds the dumbbell and pushes it upward, with the elbows inward and the chest squeezed at the same time. The dumbbell is slightly tilted forward while it is upward, forming a parabolic trajectory. When the arms are straight, the center of gravity of the dumbbell is close to the support point of the shoulder joint. But it should not be exactly at the support point of the shoulder joint, otherwise the bones will support the weight of the dumbbell, causing the chest muscles to relax and affecting the exercise effect. Then, open the two straight arms to the sides, slowly bend the arms, and let the dumbbell fall vertically. When it drops to the lowest point, it is pushed up.

[0003] After searching, for example, the utility model with application number 201822241747.2 discloses a dumbbell bench press rack, including a base, a support frame vertically installed on the base and a bracket installed above the support frame, wherein the base includes a side bottom tube and a rear bottom tube, wherein a dumbbell seat is fixedly installed at one end of the side bottom tube, wherein the rear bottom tube is fixedly connected to the other ends of the two side bottom tubes. When fitness personnel use dumbbells to perform bench press exercises, they usually hold the dumbbells until the moment of exhaustion. At this time, fitness personnel usually choose to throw the dumbbells directly on the ground. Due to the heavy weight of the dumbbells, the dumbbells will generate a huge impact force on the ground at the moment of landing. If the ground of the gym or home is not protected against impact, the impact force generated by the dumbbells will directly damage the ground of the gym or home. Therefore, in order to solve the above defects, the inventor proposes a double dumbbell bench press equipment with a ground protection function. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The utility model discloses a double dumbbell bench press device with a ground protection function, such as Figure 1 As shown, it includes a bed 1, and the user can lie on the surface of the bed 1. Support columns 2 are fixedly installed on both sides of the bottom surface of the bed 1, and rotating rods 5 are movably installed on both sides between the two support columns 2. Protective blocks 3 are fixedly installed on the outer surfaces of the two rotating rods 5. When the rotating rods 5 rotate, the protective blocks 3 can be driven to rotate, so that the protective blocks 3 can be stored when not in use. Support blocks 4 are fixedly installed on both sides of the bed 1.

[0024] like Figure 2 As shown, a buffer cavity 301 is provided on one side of the protection block 3, and a plurality of spring buffers 302 are fixedly installed inside the buffer cavity 301. A support plate 303 is fixedly installed on the top surface of the spring buffer 302, and a first rubber pad 304 is fixedly installed on the top surface of the support plate 303. When the dumbbell falls, it can fall and contact with the first rubber pad 304, thereby pushing the support plate 303 to fall. The spring buffer 302 will reduce the impact force of the dumbbell when it falls, and at the same time, it also avoids the direct contact between the fallen dumbbell and the ground. A second rubber pad 305 is fixedly installed on the outer bottom surface of the protection block 3.

[0025] It should be noted that a panel 306 is fixedly mounted on one side of the top surface of the protection block 3 , which can effectively prevent the dumbbell that falls onto the first rubber pad 304 from rolling to the ground.

[0026] like Figure 3 As shown, a gear 501 is fixedly mounted on one side of the two rotating rods 5. When the gear 501 rotates, the rotating rod 5 can be driven to rotate.

[0027] Two fixed plates 502 are fixedly installed on one side of the support column 2, a first threaded rod 503 is movably installed on one side between the two fixed plates 502, and a first sliding rod 504 is fixedly installed on the other side between the two fixed plates 502, a rack 505 is movably connected to the outer surface of the first threaded rod 503, and the rack 505 is movably connected to the first sliding rod 504, and then when the first threaded rod 503 rotates, it can drive the rack 505 to rise and fall, and the first sliding rod 504 can prevent the rack 505 from rotating with the rotation of the first threaded rod 503.

[0028] A motor 506 is fixedly installed on one side of the two fixed plates 502, and the output end of the motor 506 is fixedly connected to the first threaded rod 503. The motor 506 can drive the first threaded rod 503 to rotate, and the rack 505 is engaged with the two gears 501. When the rack 505 is raised or lowered, it can drive the two gears 501 to rotate, and then drive the two rotating rods 5 to rotate.

[0029] like Figure 4 As shown, two second slide bars 401 are fixedly installed inside the support block 4 , and the outer surfaces of the two second slide bars 401 are movably connected with a lifting block 402 , which can be lifted and lowered along the second slide bars 401 .

[0030] A placement plate 404 is fixedly installed on one side of the lifting block 402. When the lifting block 402 is lifted or lowered, the placement plate 404 can be driven to lift or lower. An electric push rod 403 is fixedly installed inside the support block 4, and the output end of the electric push rod 403 is fixedly connected to the lifting block 402. The electric push rod 403 can push the lifting block 402 to lift or lower.

[0031] Following the above practical example, Figure 5 As shown, two placement blocks 4041 are fixedly installed on one side of the placement plate 404 , and dumbbells can be placed in the two placement blocks 4041 .

[0032] Two connecting plates 4042 are fixedly installed on one side of the placement plate 404, and one side of the two connecting plates 4042 is movably connected with a second threaded rod 4043. One end of the two second threaded rods 4043 is movably connected to a limit block 4044. Rotating the second threaded rod 4043 can push the limit block 4044 down.

[0033] The working principle of the utility model is as follows: when in use, the motor 506 is first started to drive the first threaded rod 503 to rotate, and as the first threaded rod 503 rotates, the rack 505 can be driven to rise, so as to drive the two gears 501 to rotate, and the two rotating rods 5 can be rotated to make the two protection blocks 3 contact the ground, and then the user lies on the surface of the platform 1 and rotates the second threaded rod 4043 to drive the limit block 4044 to rise, and then the electric push rod 403 is started to drive the lifting block 402 and the placement plate 404 to descend, so that the user can take down the dumbbells for exercise, and after exercise, the user can directly throw the dumbbells down, and the dumbbells will contact the first rubber pad 304, thereby preventing the dropped dumbbells from directly contacting the ground.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
