[0022] This application provides a Smith machine, such as... Figures 1-8 As shown, the Smith machine includes a frame 1, two sets of guide components 2, and two sets of positioning components 3.

[0023] like Figures 1-8 As shown, frame 1 includes two vertically arranged first longitudinal beams 111. Frame 1 also includes two vertically arranged second longitudinal beams 112, with each second longitudinal beam 112 forming a group with one of the first longitudinal beams 111. Frame 1 also includes two horizontally arranged first transverse beams 121, with each first transverse beam 121 connecting the first longitudinal beams 111 and the second longitudinal beams 112.

[0024] The frame 1 also includes two horizontally arranged second crossbeams 122, one of which connects to two first longitudinal beams 111, and the other connects to two second longitudinal beams 112.

[0025] In some embodiments, the two first crossbeams 121 and the two second crossbeams 122 are located on the same side, for example, as shown in the figure. Figure 1 As shown, the two first crossbeams 121 and the two second crossbeams 122 are located on the upper side of the frame 1, forming a quadrilateral support structure. The frame 1 also includes two third crossbeams 123 located on the other side, each third crossbeam 123 connecting two first longitudinal beams 111 or two second longitudinal beams 112 or one first longitudinal beam 111 and one second longitudinal beam 112 on the other side.

[0026] Through the above construction, frame 1 has a stable structure that is not easily deformed and can provide reliable support during training.

[0027] Guide component 2 is used to guide the barbell bar 4 to move in a set direction. For example... Figure 1 , Figure 4 , Figure 5 and Figure 8 and Figure 9 As shown, two sets of guide components 2 are respectively set with two first longitudinal beams 111. Each set of guide components 2 includes a swing rod 21. The first end of the swing rod 21 is rotatably connected to the frame 1. The second end of the swing rod 21 can be displaced relative to the corresponding first longitudinal beam 111 to change the angle between the swing rod 21 and the vertical direction.

[0028] Two sets of positioning components 3 are respectively set up corresponding to two sets of guiding components 2. For example Figure 1 , Figure 9 , Figure 13 and Figure 14 As shown, each positioning assembly 3 includes: an adjustment plate 31, a positioning frame 32, and a locking element 33.

[0029] The adjusting plate 31 is installed on the corresponding swing rod 21. The adjusting plate 31 extends from the swing rod 21 toward the corresponding first longitudinal beam 111. Multiple adjusting holes 311 are provided on the adjusting plate 31 at intervals. The multiple adjusting holes 311 are located on a circle with the rotation center of the corresponding swing rod 21 as the center.

[0030] The positioning frame 32 is installed on the side of the corresponding first longitudinal beam 111. At least a part of the positioning frame 32 is spaced apart from the corresponding first longitudinal beam 111 and forms a plug-in part 321. The plug-in part 321 allows the adjustment plate 31 to be inserted. The positioning frame 32 has a through positioning hole 322. The positioning hole 322 and a plurality of adjustment holes 311 are located on the same circumference.

[0031] The locking member 33 passes through the positioning hole 322 on the positioning frame 32 and an adjustment hole 311 on the adjustment plate 31, and is inserted into the insertion part 321 to lock the corresponding swing rod 21 at the corresponding angle.

[0032] In the above embodiment, the swing rod 21 of the guide component 2 is designed to be rotatably connected to the frame 1, which can change the angle between the swing rod 21 and the vertical direction, thereby adjusting the movement direction of the barbell bar 4. Multiple adjustment holes 311 are provided on the adjustment plate 31 corresponding to different preset angles between the swing rod 21 and the vertical direction. When the swing rod 21 is adjusted to the required angle, the corresponding adjustment hole 311 aligns with the positioning hole 322 on the positioning frame 32. By inserting the locking piece 33, the angle of the swing rod 21 is locked. During subsequent training, the barbell bar 4 will move along the selected angle for bench press and other exercises, meeting the needs of diverse training angles. This allows for multi-track training using a single device, enhancing the diversity of Smith machine training scenarios.

[0033] The number and position of the adjustment holes 311 are designed according to the requirements of different training angles. In some embodiments, such as Figure 1 , Figure 9 as well as Figure 13 and Figure 14 As shown, each adjustment plate 31 is provided with two adjustment holes 311, namely a first adjustment hole 3111 near the swing rod 21 and a second adjustment hole 3112 away from the swing rod 21; when the locking member 33 is inserted into the first adjustment hole 3111, the swing rod 21 is located in the vertical direction; when the locking member 33 is inserted into the second adjustment hole 3112, the angle between the swing rod 21 and the vertical direction is 3°~10°.

[0034] In the above embodiment, two training angles are provided: the vertical direction and the oblique direction with an angle of 3° to 10° with respect to the vertical direction. The movement trajectory at the 3° to 10° inclination is more closely aligned with the direction of force applied by the arms, which can improve the comfort of the training process and reduce the risk of sports injury.

[0035] Optionally, such as Figure 13 and Figure 14 As shown, the locking element 33 can be a spring pin.

[0036] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the first end of the swing rod 21 is rotatably connected to the first longitudinal beam 111. Figure 12As shown, a rotating shaft fixing bracket 51 is installed on the first longitudinal beam 111, and a rotating shaft 52 is installed on the rotating shaft fixing bracket 51; a rotating sleeve 53 is installed at the first end of the swing rod 21, and the rotating sleeve 53 is sleeved on the outside of the rotating shaft 52 so as to rotate the first end of the swing rod 21 onto the first longitudinal beam 111.

[0037] The rotating shaft 52 is installed on the side of the first longitudinal beam 111 facing the second longitudinal beam 112. The axis of the rotating shaft 52 is perpendicular to the plane where the first longitudinal beam 111 and the second longitudinal beam 112 are located, so that the swing rod 21 swings in the plane where the first longitudinal beam 111 and the second longitudinal beam 112 are located.

[0038] In some other embodiments, the first end of the swing rod 21 may also be rotatably connected to the third crossbeam 123 that connects the first longitudinal beam 111 and the second longitudinal beam 112. The above implementation method can be referred to, and will not be repeated here.

[0039] In some embodiments, such as Figure 13 and Figure 14 As shown, the positioning frame 32 includes a fixing plate 323 and a plug-in plate 324. The fixing plate 323 extends along the side of the first longitudinal beam 111 and is fixedly connected to the first longitudinal beam 111. The plug-in plate 324 includes a first extension 3241, a second extension 3242, and a connecting portion 3243. The first extension 3241 and the second extension 3242 are arranged side by side in the vertical direction and connected to the fixing plate 323. The first extension 3241 and the second extension 3242 extend away from the fixing plate 323. The connecting portion 3243 connects the ends of the first extension 3241 and the second extension 3242 away from the fixing plate 323. A plug-in portion 321 is formed between the connecting portion 3243 and the fixing plate 323, and a positioning hole 322 is formed on the connecting portion 3243.

[0040] The above embodiment provides one implementation of the positioning frame 32. The positioning frame 32 of this structure is installed in close contact with the first longitudinal beam 111 through the fixing plate 323, which can achieve stable installation. At the same time, the plug-in plate 324 provides plug-in space for the adjustment plate 31 and cooperates with the locking member 33 to lock the angle of the swing rod 21.

[0041] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the two positioning frames 32 are respectively installed on the two opposing surfaces of the two first longitudinal beams 111. The opposing surfaces of the two first longitudinal beams 111 are the outward-facing surfaces. The positioning frames 32 are placed on them without being obstructed, which facilitates adjustment by the user during use.

[0042] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, each guide assembly 2 also includes a sliding rod 22 and a sliding sleeve 23. The sliding rod 22 is arranged side by side with the swing rod 21 and swings synchronously with the swing rod 21. The sliding sleeve 23 is sleeved on the sliding rod 22 and slides in cooperation with the sliding rod 22. The sliding sleeve 23 is used to install the barbell bar 4.

[0043] In the above embodiment, the sliding rod 22 swings with the swing rod 21 to the required angle, and the sliding sleeve 23 guides the barbell bar 4 to move along the axial direction of the sliding rod 22, thereby realizing the movement of pushing the barbell bar 4 in the set direction.

[0044] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 11 As shown, a guide member 6 is installed on the first crossbeam 121. The guide member 6 is located close to the first longitudinal beam 111. A guide portion 601 is formed in the guide member 6 along the swing path of the sliding rod 22 following the swing of the swing rod 21. The end of the sliding rod 22 that swings with the swing rod 21 is inserted into the guide portion 601 and can slide along the guide portion 601.

[0045] The first crossbeam 121 is close to the second end of the swing rod 21, that is, close to the swing end of the swing rod 21. A guide member 6 is provided on the first crossbeam 121, and the guide member 6 is provided with a guide part 601 for the end of the sliding rod 22 to be inserted. The guide part 601 can guide the swinging motion of the sliding rod 22, so that the sliding rod 22 and the swing rod 21 swing along a specific motion trajectory.

[0046] In some embodiments, such as Figure 15 As shown, the guide member 6 includes a first mounting plate 61, a second mounting plate 62, and a guide plate 63. The first mounting plate 61 is mounted on one side of the first crossbeam 121 and extends toward the swing rod 21; the second mounting plate 62 is mounted on the other side of the first crossbeam 121 and extends toward the swing rod 21, with the first mounting plate 61 and the second mounting plate 62 opposite to each other; the guide plate 63 connects the ends of the first mounting plate 61 and the second mounting plate 62 away from the first crossbeam 121, and a guide hole 631 is provided on the guide plate 63 through the swing path of the sliding rod 22 along the swing rod 21; a guide space is formed between the first mounting plate 61, the second mounting plate 62, and the guide plate 63, and the end of the sliding rod 22 is inserted into the guide space through the guide hole 631.

[0047] In the above embodiments, a specific implementation of the guide member 6 is provided. The guide member 6 consists of a first mounting plate 61, a second mounting plate 62, and a guide plate 63. The guide member 6 can be a sheet metal part integrally formed by stamping. The swing end of the sliding rod 22 is inserted into the guide member 6 through the guide hole 631, and the swing end of the sliding rod 22 is guided to slide through the guide hole 631. In addition, the length design of the guide hole 631 can also limit the swing stroke of the sliding rod 22, preventing the swing rod 21 and the sliding rod 22 from being not effectively fixed and causing large-scale swinging if the locking member 33 is not locked during the angle adjustment process, which could lead to accidental injury to equipment or personnel.

[0048] In some embodiments, the guide hole 631 is formed as an elongated hole arranged along the axial direction of the first crossbeam 121, thereby restricting the swing path of the sliding rod 22 to the axial direction of the first crossbeam 121, so that the swing rod 21 and the sliding rod 22 swing in the plane containing the first longitudinal beam 111 and the second longitudinal beam 112.

[0049] In some embodiments, such as Figure 15 As shown, a sliding guide 7 is installed at the end of the sliding rod 22 that is inserted into the guide space. The size of the sliding guide 7 is larger than the size of the guide hole 631, thereby restricting the sliding rod 22 from coming out of the guide hole 631.

[0050] In some embodiments, the sliding guide 7 is a guide bearing, the outer diameter of which is adapted to the distance between the first mounting plate 61 and the second mounting plate 62, such that the two radial sides of the guide bearing contact the inner walls of the first mounting plate 61 and the second mounting plate 62 respectively, thereby ensuring that the end of the sliding rod 22 swings along a straight line.

[0051] Because the swing end of the sliding rod 22 makes an arc-shaped movement, the sliding guide 7 installed at the end of the sliding rod 22 also makes an arc-shaped movement. In order to cooperate with the sliding guide 7 at the end of the sliding rod 22, in some embodiments, the guide plate 63 is inclined from the side near the first longitudinal beam 111 to the side away from the first longitudinal beam 111, and the inclination direction gradually moves away from the first cross beam 121, such as... Figure 4 and Figure 5 As shown; or, the guide plate 63 is designed as an arc-shaped plate with the pivot 52 as the center (not shown in the figure).

[0052] Through the above design, the guide plate 63 can better guide the end of the sliding rod 22 to slide along a specific trajectory. The first mounting plate 61 and the second mounting plate 62 are adjusted to adapt to the shape of the guide plate 63.

[0053] In some embodiments, such as Figure 11As shown, a stop 64 is provided at one end of the guide plate 63 away from the first longitudinal beam 111. The stop 64 includes a stop plate 641 and a buffer portion 642 mounted on the stop plate 641. The buffer portion 642 is disposed facing the sliding rod 22. The buffer portion 642 is configured to abut against the sliding rod 22 before the sliding rod 22 moves along the guide hole 631 and contacts the edge of the guide hole 631 near the stop 64, thereby restricting the sliding rod 22 from continuing to move.

[0054] By setting the stop 64, a buffer effect can be formed at the end of the swing path of the sliding rod 22, so as to avoid the sliding rod 22 from frequently hitting the guide 6 during the adjustment of the angle, which would damage the guide 6 and affect the service life of the component. In addition, the buffer part 642 on the stop 64 can reduce the noise generated during the collision and improve the user experience.

[0055] In some embodiments, the two first mounting plates 61 of the two guide members 6 are respectively located on the sides of the two first crossbeams 121 that are far apart from each other, and a logo plate 8 is installed on the first mounting plate 61 for aesthetic and promotional purposes.

[0056] In some embodiments, such as Figure 10 As shown, the second end of the swing rod 21 is bent to form an assembly part 211. The assembly part 211 has a through assembly hole 212. The sliding rod 22 passes through the assembly hole 212 and its end is inserted into the guide part 601. The assembly part 211 is sleeved on the sliding rod 22 through the assembly hole 212. This structure enables the swing rod 21 and the sliding rod 22 to swing synchronously.

[0057] In some embodiments, such as Figure 1 and Figure 9 As shown, the swing bar 21 is provided with multiple support parts 213 along its length. The multiple support parts 213 are located on the side of the swing bar 21 away from the adjustment plate 31 and are bent obliquely upward. The barbell bar 4 is equipped with a hook 9, which cooperates with the support parts 213 to limit the downward sliding of the barbell bar 4.

[0058] By setting a support part 213 on the swing arm 21 and installing a hook 9 on the barbell bar 4, the hook 9 can be hooked by the support part 213 during the downward sliding of the barbell bar 4, preventing the barbell bar 4 from continuing to slide down, preventing the barbell bar 4 from accidentally falling off and hitting the user during training, avoiding user injury, and improving the safety of the Smith machine.
