Description

Technical Field

[0001] This utility model relates to the field of pull-up machine technology, and in particular to a multifunctional pull-up machine. Background Technology

[0002] Pull-up machines are a common type of exercise equipment, frequently used in physical education classes and gyms. Existing pull-up machines are typically single-bar machines, limiting their use to pull-ups. While a later Chinese utility model patent (CN205516146U) disclosed a pulley-assisted abdominal toning and waist-twisting supine board, integrating pull-ups, parallel bars, a supine board, and a waist-toning machine into one unit for comprehensive exercise, the supine board itself only functions as a sit-up machine. Furthermore, its design is extremely inconvenient to disassemble; it cannot be removed when not in use for sit-ups. This not only takes up space and interferes with other exercises but also increases manufacturing costs, raising the overall cost for users. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0035] Example 1: See Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a multifunctional pull-up machine includes a base frame 1 and support rods 2 symmetrically distributed on the base frame 1. Each support rod 2 is equipped with a lifting arm 3. A crossbar 4 is provided on the upper part of the symmetrically distributed support rods 2, and a bent rod 5 is provided on the crossbar 4. The bent rod 5 is fixedly connected to the corresponding support rod 2. In this embodiment, the bent rod 5 and the corresponding support rod 2 are fixed together by locking parts (screws), which is beneficial to the user for safer and more stable use. A connecting rod 6 is provided between the base frame 1 and the corresponding support rod 2. The connecting rods 6 are symmetrically distributed. A detachable sit-up device 7 is provided between the symmetrically distributed connecting rods 6. An installation device 8 for installing the sit-up device 7 is provided on the symmetrically distributed support rods 2. When the sit-up device 7 is installed on the installation device 8, it forms a backrest. This sit-up device 7 forming a backrest not only helps to prevent body swaying during pull-up exercises and helps to stabilize the center of gravity, but also provides the user with rest support and safety protection.

[0036] Example 2: This can be explained based on Example 1, such as... Figure 2 As shown, the sit-up device 7 includes a mounting frame 71 for detachable fixation to the connecting rod 6 or the mounting device 8. The mounting frame 71 has mounting positions 72 for mounting on the connecting rod 6 or the mounting device 8. A locking element 73 for fixing to the connecting rod 6 or the mounting device 8 is provided at the mounting position 72. A lying board 74 and a leg hook 75 are provided on the mounting frame 71. In use, the user can perform sit-ups while lying on the lying board 74. Further explanation: the mounting positions 72 are located on both sides of the mounting frame 71. This arrangement is reasonable and facilitates a more stable installation of the mounting frame 71 on the connecting rod 6 or the mounting device 8. In this embodiment, the mounting frame 71 has two mounting positions 72 on each side, which is a reasonable and easy-to-implement arrangement.

[0037] Among them, such as Figure 3As shown, the locking component 73 includes a fixed shaft 731 disposed on a mounting bracket 71 at the mounting position 72. A hook plate 732 is disposed on the fixed shaft 731 and rotates back and forth around the fixed shaft 731. After the mounting position 72 of the mounting bracket 71 is installed on the connecting rod 6 or the mounting device 8, the hook plate 732 is rotated to lock the connecting rod 6 or the mounting device 8. This facilitates the fixation of the sit-up device 7 on the connecting rod 6 or the mounting device 8. When the hook plate 732 is rotated to unlock, the mounting position 72 of the mounting bracket 71 can be disengaged from the connecting rod 6 or the mounting device 8, which is convenient for disassembly. It can be seen that this disassembly and installation is extremely convenient and beneficial to the user's operation. In this embodiment, there is one locking component 73 on each side of the mounting bracket 71. This can fix the sit-up device 7 on the connecting rod 6 or the mounting device 8 and also reduces the number of rotations of the hook plate 732, making it more convenient for the user to install and disassemble.

[0038] Example 3: This can be explained based on Example 2, such as... Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, each connecting rod 6 includes an arc-shaped rod 61 disposed between the base frame 1 and the corresponding support rod 2. The sides of the corresponding arc-shaped rods 61 are provided with fixing rods 62 for installation on the corresponding mounting positions 72. The locking member 73 can lock the fixing rods 62 on the mounting positions 72, so as to stably fix the sit-up device 7 on the corresponding connecting rods 6 for sit-ups. When it is necessary to remove the sit-up device 7, simply unlock the locking member 73, and then the sit-up device 7 can be removed from the corresponding connecting rods 6. The removed sit-up device 7 can be installed on the mounting device 8, which can be used as a back pad.

[0039] Example 4: This can be described based on Example 2 or Example 3, such as... Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the mounting device 8 includes a device base 81 mounted on symmetrically distributed support rods 2. Each symmetrically distributed device base 81 has a corresponding stabilizing rod 82 on its corresponding surface to cooperate with the mounting position 72. A locking member 73 can lock the fixing rod 62 on the mounting position 72, facilitating the stable fixing of the sit-up device 7 onto the corresponding device base 81. This not only helps prevent body swaying during pull-ups and stabilizes the center of gravity, but also provides the backrest with rest support and safety protection. When the sit-up device 7 needs to be removed, simply unlock the locking member 73, and then the sit-up device 7 can be removed from the corresponding device base 81 and mounted on the corresponding connecting rod 6. This device allows for sit-up exercises, offering multiple functions and greater convenience for users, meeting their needs.

[0040] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 2 , Figure 7 and Figure 8 As shown, the base frame 1 is equipped with a foot hook 11. This design makes it easier to hook the feet when performing sit-up exercises, thus facilitating better exercise.

[0041] Example 6: This can be described based on Example 1, Example 2, Example 3, Example 4, or Example 5, such as... Figure 1 and Figure 6 As shown, the lifting arm 3 includes an arm body 31, an elbow pad 32 is provided on the upper surface of the arm body 31, and a double bar 33 is provided at the front of the arm body 32, which is beneficial for users to exercise their arm strength.

[0042] Example 7: This can be described based on Example 1, Example 2, Example 3, Example 4, Example 5, or Example 6, such as... Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, each support rod 2 is equipped with a climbing rock 21 at its top. The climbing rock 21 helps to simulate rock climbing exercises and increase arm and finger strength. Furthermore, each support rod 2 is also fixedly equipped with a pull rope 22, on which a handle 23 is attached. This arrangement facilitates arm strength training for the user.

[0043] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0044] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
