Technical Field
[0001] The utility model relates to the technical field of bench press training devices, in particular to a bench press training device with a limiting structure. Background Art
[0002] One form of bench press training device is one with a limit structure, which can help people doing bench press training better control the movement path and range of the barbell during exercise, and prevent sports injuries caused by excessive or violent movements.
[0003] In most of the existing bench press training devices, the limit plates are fixedly installed on the support columns at both ends, and the limit baffles arranged at both ends can play a protective role when the dumbbells fall accidentally.
[0004] However, the limit plate of this design still has some defects in actual use. In actual use, when the trainee suffers from muscle fatigue, he will not be able to continue to support the dumbbells, which will cause the dumbbells to fall. Since the trainee holds the dumbbells in his hands, when the dumbbells fall to the fixed limit baffle, the wrist will be subjected to a huge impact force, which can easily cause wrist injuries to the trainee.
[0005] Therefore, it is necessary to provide a bench press training device with a limiting structure to solve the above technical problems. Utility Model Content
[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a bench press training device with a limiting structure, which can reduce the impact force when the dumbbell falls through a spring buffer, thereby protecting the wrists of the trainees.

DETAILED DESCRIPTION
[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0024] First embodiment:
[0025] like Figure 1-3 As shown, the bench press training device with a limiting structure provided by the utility model comprises: a trainer 100, the trainer 100 comprises: a support frame 101, the support frame 101 is installed on the upper end of a support bottom plate 102, and the support frame 101 is welded to a seat 103 at one end, a top plate 107 is installed on the upper end of the support frame 101, and a limiting support 105 is symmetrically arranged at the center of the upper end of the support bottom plate 102, a placement seat is arranged at one end side of the limiting support 105, and a dumbbell equipment 104 is placed in the placement seat, and a limiting component 200 is arranged on the limiting support 105, and the limiting component 200 comprises: a limiting bottom frame 201, the interior of the limiting bottom frame 201 is a cavity structure, and two supporting seats 205 are symmetrically fixedly arranged on the upper end of the limiting bottom frame 201. A shock absorbing spring 206 is provided at the upper end of the two support seats 205, and the shock absorbing spring 206 is fixedly connected to the upper end limit plate 207. In actual use, through the provided limit support 105 and the limit assembly 200, through the coordinated use of the limit bottom frame 201 and the limit plate 207, when the dumbbell falls, the limit of the limit plate 207 can prevent the dumbbell from pressing the trainee, and by arranging the shock absorbing spring 206 at the lower end of the limit plate 207, the impact force when the dumbbell falls can be reduced, thereby reducing the impact force on the wrist. At the same time, the use of the shock absorbing spring 206 enables the limit plate 207 to be elastically supported, thereby increasing the stability of the trainee's movements, allowing the trainee to focus more on the contraction and relaxation of the muscles, thereby improving the training effect.
[0026] Second embodiment:
[0027] like Figure 2As shown, a plurality of positioning grooves 106 are provided at the lower end of the limit support 105, and the plurality of positioning grooves 106 at the outer end of the limit support 105 are through-hole designs, while the plurality of positioning grooves 106 at the inner end are not through-holes. By setting the limit support 105 and the plurality of positioning grooves 106, in actual use, due to the differences in the body shapes of the trainees, the limit bottom frame 201 and the limit bolt 202 are used in conjunction with the plurality of positioning grooves 106, so that the trainees can adjust the height of the limit plate 207 according to their own height, so as to better adapt to the training.
[0028] Third embodiment:
[0029] like Figure 3 As shown, the interior of the limiting bottom frame 201 is designed as a cavity, the cavity and the limiting bolt 202 are embedded and connected through, and the caliber size of the cavity and the limiting bolt 202 is the same as the caliber size of the positioning groove 106. By using the limiting bottom frame 201 and the limiting bolt 202 in coordination, the limiting bottom frame 201 can be quickly installed and disassembled. In actual use, it is only necessary to pull the limiting bolt 202 out of the inner cavity of the limiting bottom frame 201. Compared with the traditional welding method, it is more convenient in installation, disassembly and height adjustment.
[0030] Fourth embodiment:
[0031] like Figure 3 As shown, a through hole is provided at one end of the limit bolt 202, which is matched with the fixing bolt 203, and a clamping strip 204 is provided at one end of the fixing bolt 203. In actual use, in order to prevent the limit bolt 202 from being detached from the limit bottom frame 201 when the limit bolt 202 is subjected to the impact force when the dumbbell falls, the fixing bolt 203 is matched through the through hole at one end of the limit bolt 202. When in use, the fixing bolt 203 is inserted into the through hole provided by the limit bolt 202, and then the clamping strip 204 is clamped with the fixing bolt 203.
[0032] Fifth embodiment:
[0033] like Figure 2-4 As shown, a threaded bolt 111 is provided on the end side of the limit support 105, one end of the threaded bolt 111 is connected to the adjustment plate 110, the upper end of the adjustment plate 110 is connected to the upper plate 108, and a slider 208 is provided on the upper end of the adjustment plate 110, and the slider 208 is slidably connected in a slide groove 109 opened at the bottom of the upper plate 108. In actual use, through the cooperation of the threaded bolt 111 and the adjustment plate 110, when the threaded bolt 111 is screwed, the adjustment plate 110 moves in the slide groove 109 provided on the upper plate 108, and the left and right distance is adjusted by the adjustment plate 110, so that the dumbbells at both ends are limited to the outside, which can prevent the dumbbell equipment 104 from tilting to the side due to the unstable lifting center during training, causing training hazards to the trainees.
[0034] Working principle: In actual use, the trainee first adjusts the left and right distance through the adjustment plate 110 so that the dumbbells at both ends are limited to the outside, and then sits on the seat 103. After adjusting the posture, the dumbbell equipment 104 is picked up. When the trainee is unable to continue to support the dumbbells due to muscle fatigue, when the dumbbells fall, the limit support 105 and the limit assembly 200 are set, and the limit bottom frame 201 and the limit plate 207 are used in coordination. The limit of the limit plate 207 can prevent the dumbbells from pressing on the trainee, and the shock-absorbing spring 206 is set at the lower end of the limit plate 207 to reduce the impact force when the dumbbells fall, thereby reducing the impact force on the wrist.
[0035] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
