AI Technical Summary
In the prior art, for strength trainers, more shoulder force is required to push up with a movable barbell push rod, and when the shoulder force is insufficient, the push rod is likely to be pressed down, which poses a safety hazard.
A grip movable bench press rod with a locking structure is designed, adopting a bidirectional screw and a threaded sleeve structure. The friction between the threaded sleeve and the two-way screw is adjusted through the limiting ring and friction plate on the threaded sleeve, so that the sliding resistance of the push rod is adjustable.
By adjusting the fit between the friction plate and the bidirectional screw, increasing the friction between the threaded sleeve and the bidirectional screw, the shoulder strength required by the strength trainer when pushing the rod is reduced, avoiding the push rod down, and improving the safety and comfort of training.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fitness equipment, in particular to a bench press rod with a movable handle and a locking structure. Background Art
[0002] Barbell is a kind of core training sports training equipment, and also a weightlifting equipment, which can be used to increase muscle strength and conduct core training. Barbells are usually composed of three parts: barbell bar, barbell plates and clamps. Among them, the barbell bar is the core part, which is generally 2.20 meters long (men's barbell) or 2.15 meters (women's barbell), weighing 20 kilograms (men's barbell) or 15 kilograms (women's barbell). Barbell plates are available in a variety of weights and colors to facilitate training of different intensities. Standard barbell: It consists of a push rod, barbell plates and clamps, which are suitable for various weightlifting and fitness training. Non-standard barbell: The structure is the same as the standard barbell, but the size requirements are not strict, the production requirements are not high, and the weight can be freely specified. In addition, there are various special barbells, such as flexion barbells, bow barbells and ring barbells, to meet specific training needs. Barbell training can exercise the muscles of the whole body, especially the muscles of the shoulders, back, arms, chest, etc. Through different training movements and weight selection, you can achieve the effects of strengthening muscle strength, improving body coordination, and improving sports performance. At the same time, barbell training can also help burn fat, shape body lines, increase bone density, and prevent osteoporosis.
[0003] When using a barbell, in order to ensure the convenience of using the barbell, the handle on the grip bar is traditionally movable so that the grip can be more targeted. However, for strength trainers, this kind of push rod in the prior art requires more shoulder strength to push up, and for strength trainers, when the shoulder strength is insufficient, the push rod is easily pressed down. Therefore, the adjustable sliding resistance of the threaded sleeve can better protect the safety of strength trainers and avoid the dangerous situation of strength trainers being squeezed by the push rod. Therefore, a bench press rod with a movable grip and a locking structure is urgently needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a bench press rod with a movable handle having a locking structure, which solves the problem that the push rod with a movable handle in the prior art requires more shoulder strength to be pushed up by the strength trainer, and when the shoulder strength is insufficient, the push rod is easily pressed down.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A bench press rod with a movable handle and a locking structure comprises a bidirectional screw, both ends of which are rotatably connected to barbell plates, both ends of which are connected to threaded sleeves by threaded engagement, and one side of the two threaded sleeves is fixedly connected to a limiting ring, the inner sides of the two limiting rings are provided with friction plates, and the tops of the two friction plates are rotatably connected to threaded rods, and the tops of the two threaded rods respectively penetrate the tops of the two limiting rings.
[0007] Preferably, both ends of the bidirectional screw are rotationally connected to one side of the two barbell plates through a rotating shaft.
[0008] Preferably, the top ends of the two threaded rods pass through the tops of the two limiting rings respectively through the threaded grooves.
[0009] Preferably, the two thread sleeves are symmetrically distributed along the center of the bidirectional screw.
[0010] Preferably, the bottom ends of the two threaded rods are rotatably connected to the tops of the two friction plates respectively through a rotating shaft.
[0011] Preferably, the two barbell plates are symmetrically distributed along the center of the bidirectional screw.
[0012] The utility model has at least the following beneficial effects:
[0013] The utility model discloses a movable bench press rod with a locking structure, wherein the handle push rod is a bidirectional screw rod. First, the user lies flat, holds two threaded sleeves with both hands respectively, and pushes up the bidirectional screw rod and two barbell plates, and moves the two threaded sleeves inwards. At this time, the bidirectional screw rod rotates. When the tightness of the threaded sleeve needs to be adjusted, the two threaded rods are rotated manually, so that the friction plate can be driven to move toward the bidirectional screw rod, so as to make the friction plate fit the bidirectional screw rod, so as to increase the friction force between the threaded sleeve and the bidirectional screw rod. Compared with the push rod in the prior art whose handle can be moved, it is necessary for strength trainers to call on more shoulder strength to push it up. When the shoulder strength is insufficient, the push rod is easily pressed down. The method proposed in the utility model manually rotates the two threaded rods, thereby driving the friction plate to move toward the bidirectional screw rod, so as to make the friction plate fit the bidirectional screw rod, increase the friction force between the threaded sleeve and the bidirectional screw rod, and make the barbell strength trainer's movements more stretched and more in line with human mechanics.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] Reference Figure 1-4A movable bench press rod with a locking structure and a handle comprises a bidirectional screw rod 1, both ends of the bidirectional screw rod 1 are rotatably connected with barbell plates 2, both ends of the bidirectional screw rod 1 are connected with threaded sleeves 3 through threaded engagement, and one side of the two threaded sleeves 3 is fixedly connected with a limiting ring 4, the inner sides of the two limiting rings 4 are provided with friction plates 6, and the setting of the friction plates 6 makes the sliding resistance of the screw rod 3 adjustable. The function of the adjustable resistance is to make different settings for trainers with different strengths. For example, for trainers with weak shoulder strength, the friction plates 6 can be set to fit the bidirectional screw rod 1 at the beginning, thereby returning to the conventional use form of the bench press rod, while for trainers with strong shoulder strength, the friction plates 6 can be set to fit the bidirectional screw rod 1 at the beginning, thereby returning to the conventional use form of the bench press rod, and ... For strong trainers, the friction plate 6 can be adjusted to a state where it is completely disengaged from the bidirectional screw 1. Therefore, the design of the friction plate 6 allows the product to cope with different strength trainers while improving the safety of the product. The tops of the two friction plates 6 are rotatably connected to the threaded rods 5, and the tops of the two threaded rods 5 respectively pass through the tops of the two limit rings 4. Specifically, the two threaded rods 5 are manually rotated to drive the friction plate 6 to move toward the bidirectional screw 1, so as to make the friction plate 6 fit with the bidirectional screw 1, thereby increasing the friction between the threaded sleeve 3 and the bidirectional screw 1, so that the barbell strength trainers' movements are more stretched and more in line with human mechanics.
[0022] This program has the following working process:
[0023] When using the movable bench press bar with a locking structure, the user first lies flat and holds the two threaded sleeves 3 with both hands respectively, and pushes up the bidirectional screw rod 1 and the two barbell plates 2, and moves the two threaded sleeves 3 toward the inside. At this time, the bidirectional screw rod 1 rotates. When the tightness of the threaded sleeve 3 needs to be adjusted, the two threaded rods 5 are rotated manually, so that the friction plate 6 can be driven to move toward the bidirectional screw rod 1, so as to make the friction plate 6 fit the bidirectional screw rod 1, so as to increase the friction force between the threaded sleeve 3 and the bidirectional screw rod 1.
[0024] According to the above working process, we can know that:
[0025] By manually rotating the two threaded rods 5, the friction plate 6 can be driven to move toward the bidirectional screw 1, so as to make the friction plate 6 fit the bidirectional screw 1, thereby increasing the friction between the threaded sleeve 3 and the bidirectional screw 1, making the barbell strength trainer's movements more stretched and more in line with human body mechanics.
[0026] Furthermore, both ends of the bidirectional screw rod 1 are rotatably connected to one side of the two barbell plates 2 through a rotating shaft. Specifically, the bidirectional screw rod 1 will not drive the two barbell plates 2 to rotate.
[0027] Furthermore, the top ends of the two threaded rods 5 pass through the tops of the two limiting rings 4 respectively through the threaded grooves 7 .
[0028] Furthermore, the two thread sleeves 3 are symmetrically distributed along the center of the bidirectional screw 1 .
[0029] Furthermore, the bottom ends of the two threaded rods 5 are rotationally connected to the tops of the two friction plates 6 through rotating shafts. Specifically, by adjusting the two friction plates 6, the friction degree between the threaded sleeve 3 and the bidirectional screw 1 can be adjusted at any time.
[0030] Furthermore, the two barbell plates 2 are symmetrically distributed along the center of the bidirectional screw 1 .
[0031] In summary: the bidirectional screw rod 1 will not drive the two barbell plates 2 to rotate, and the friction degree between the threaded sleeve 3 and the bidirectional screw rod 1 can be adjusted at any time by adjusting the two friction plates 6.
[0032] The above shows and describes the basic principle, main features and 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 the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
