Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically a bench press fitness exercise device. Background Technology

[0002] As people's living standards continue to improve, they are paying more and more attention to their health, leading to a surge in various fitness activities and the emergence of a wide range of fitness equipment. Heavy workloads and family chores mean that most people don't have fixed times to go to the gym for systematic training. Therefore, fitness plazas in residential areas and parks have sprung up, with various fitness equipment neatly arranged, allowing fitness enthusiasts to exercise at any time. Among the many sports, the bench press is a widely popular strength training exercise. The bench press, also known as bench press training, includes three forms: flat bench press, incline bench press, and decline bench press, which can train various muscle groups in the arms, shoulders, chest, and back.

[0003] For example, the utility model patent with authorization announcement number CN218793721U discloses a bench press training device. This device uses a moving part to push two third benches horizontally away from each other, so that the training bench can be used by trainees with different shoulder widths. The tops of the first, second, and third benches are level. When using it, the user lies on the first, second, and two third benches, holds the bar, and rotates the swing arm by extending the arm upward. The counterweight component is installed on the swing arm to form resistance, thereby achieving the exercise effect. It is simple and convenient to use.

[0004] However, in actual use, the device requires the user to lie on the recliner and slowly move to find the best training position. Also, each time the number of weights is adjusted, the threaded barrels on both sides need to be rotated and the fixing rods need to be removed in order to add or remove weights, which is quite cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide a bench press fitness exercise device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bench press fitness exercise device includes: a base, a reclining chair mounted on the base, a movable slide seat slidably mounted on the base via a movable slide rail, a pair of pressing frames mounted on the movable slide seat, pressing seats mounted on the pressing frames, and pressing bars slidably inserted into the pressing seats; a moving mechanism mounted on the base for adjusting the position of the pressing frames; and a buffer mechanism mounted on the pressing frames for dissipating force from the pressing bars.

[0008] As a preferred embodiment, the moving mechanism includes a pair of movable mounting seats mounted on a base, a movable lead screw rotatably mounted between the movable mounting seats, a movable slider threaded onto the movable lead screw, the movable slider being fixedly connected to a movable slide block, and a movable motor mounted at the end of each movable mounting seat, the output end of the movable motor being drivenly connected to the shaft end of the movable lead screw.

[0009] As a preferred embodiment, the lifting seat has a vertically arranged lifting groove, and the lifting rod is slidably inserted into the lifting groove.

[0010] As a preferred embodiment, the lifting seat is further provided with an inclined limiting groove at the position corresponding to the lifting groove.

[0011] As a preferred embodiment, limit baffles are also installed on both sides of the lifting rod, the limit baffles being located outside the lifting seat. A counterweight is fitted onto the lifting rod, and a locking block is also fitted onto the lifting rod. The locking block, in conjunction with the limit baffles, clamps the counterweight. A locking nut seat is installed on the locking block, and a locking screw is threaded into the locking nut seat, with the end of the locking screw abutting against the lifting rod.

[0012] As a preferred embodiment, the buffer mechanism includes a buffer groove and an auxiliary groove opened on the outer side of the lifting frame. The auxiliary groove and the buffer groove are separated by a buffer seat. A buffer plate is slidably inserted into the buffer groove. A buffer rod is also slidably inserted into the buffer seat. The upper end of the buffer rod is fixedly connected to the lower end of the buffer plate. A buffer spring is also fitted on the buffer rod. The two ends of the buffer spring abut against the corresponding side of the buffer plate and the buffer seat, respectively.

[0013] As a preferred embodiment, the lower end of the buffer rod is also fitted with an end cap, which is located within the auxiliary groove.

[0014] Compared with existing technologies, the advantages of this invention are as follows: A movable motor drives a movable screw to rotate, which in turn moves a movable slider threaded onto the screw, causing the movable slide block to move, thereby adjusting the position of the lifting bar. This allows the lifting bar to be adjusted to a comfortable position for the user, facilitating exercise. By rotating the locking screw, the locking block can be removed, allowing for the addition or removal of counterweights. Compared to requiring the rotation of two screw-on cylinders to add or remove counterweights, this method is simpler and increases the speed of counterweight adjustment, thus better meeting user needs. This invention has a reasonable structure, automatically adjusting the position of the lifting bar to help users find the optimal exercise position. It also facilitates the addition and removal of counterweights, better meeting user requirements. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-4 A bench press fitness exercise device includes: a base 1, a reclining chair 11 mounted on the base 1, a movable slide 2 slidably mounted on the base 1 via a movable slide rail 24, a pair of lifting frames 3 mounted on the movable slide 2, a lifting seat 31 mounted on the lifting frame 3, a lifting rod 4 slidably inserted into the lifting seat 31, a vertically arranged lifting groove 32 opened on the lifting seat 31, the lifting rod 4 slidably inserted into the lifting groove 32, and an inclined limiting groove 33 opened on the lifting seat 31 corresponding to the position of the lifting groove 32; the limiting groove 33 facilitates the placement of the lifting rod 4; a moving mechanism mounted on the base 1 for adjusting the position of the lifting frame 3; and a buffer mechanism mounted on the lifting frame 3 for dissipating force on the lifting rod 4.

[0022] The working principle of this utility model is as follows: When in use, the user lies down on the recliner 11, and then the moving mechanism drives the moving slide 2 to move, thereby adjusting the lifting bar 4 to a comfortable position for the user to exercise. By setting a buffer mechanism, the safety of the device can be improved and the possibility of the lifting bar 4 falling and injuring the user can be reduced.

[0023] As a further embodiment, the moving mechanism includes a pair of movable mounting seats 21 mounted on the base 1, with a movable lead screw 23 rotatably mounted between the movable mounting seats 21. A movable slider 25 is threaded onto the movable lead screw 23, and the movable slider 25 is fixedly connected to the movable slide block 2. A movable motor 22 is also mounted at the end of each movable mounting seat 21, and the output end of the movable motor 22 is drivenly connected to the shaft end of the movable lead screw 23.

[0024] The working principle of the moving mechanism is as follows: When moving, the moving motor 22 is started, which drives the moving screw 23 to rotate, thereby causing the moving slider 25, which is threaded on the moving screw 23, to move the moving slide block 2, thereby realizing the adjustment of the position of the lifting bar 4. The lifting bar 4 can be adjusted to a comfortable position for the user to exercise.

[0025] As a further embodiment, limit baffles 41 are installed on both sides of the lifting rod 4. The limit baffles 41 are located outside the lifting seat 31. A counterweight is fitted on the lifting rod 4. A locking block 42 is also fitted on the lifting rod 4. The locking block 42 cooperates with the limit baffles 41 to clamp the counterweight. A locking nut seat 43 is installed on the locking block 42. A locking screw 44 is threaded into the locking nut seat 43. The end of the locking screw 44 abuts against the lifting rod 4.

[0026] When the number of counterweights needs to be adjusted, rotate the locking screw 44 to separate the end of the locking screw 44 from the lifting rod 4. Then, remove the locking block 42 from the end of the lifting rod 4. Immediately afterwards, the number of counterweights can be adjusted. After the adjustment is completed, put the locking block 42 on and let it work with the limit stop 41 to clamp the counterweights. Then rotate the locking screw 44 so that its end abuts against the lifting rod 4 to prevent the locking block 42 from moving. The installation work is now complete. Compared to rotating two threaded barrels to add or remove counterweights, this method is simple and can improve the speed of counterweight adjustment, thus better meeting the needs of use.

[0027] As a further embodiment, the buffer mechanism includes a buffer groove 5 and an auxiliary groove 51 opened on the outer side of the lifting frame 3. The auxiliary groove 51 and the buffer groove 5 are separated by a buffer seat 53. A buffer support plate 52 is slidably inserted into the buffer groove 5. A buffer rod 54 is also slidably inserted into the buffer seat 53. The upper end of the buffer rod 54 is fixedly connected to the lower end of the buffer support plate 52. A buffer spring 55 is also fitted on the buffer rod 54. The two ends of the buffer spring 55 respectively abut against the corresponding side of the buffer support plate 52 and the buffer seat 53. In this embodiment, an end cap is also installed at the lower end of the buffer rod 54. The end cap is located in the auxiliary groove 51.

[0028] The working principle of the buffer mechanism is as follows: when the lifting rod 4 slips off, the buffer plate 52 supports the lifting rod 4, and then the lifting rod 4 presses down against the buffer plate 52. At this time, the buffer spring 55 is compressed, which can effectively reduce the instantaneous impact force generated by the lifting rod 4 falling off and improve the safety of the device.
