[0002] With the continuous improvement of people's living standards and the increasing awareness of health, fitness has become an important way for people to relax and relieve stress. Different fitness equipment can assist users in targeted exercises for specific body parts. Among them, the door-mounted pull-up bar is a common indoor fitness equipment, mainly used for pull-ups and other exercises installed on a door frame. When using it, simply adjust the telescopic mechanism on the bar to securely lock it to the door frame. It allows for exercise in limited space and during spare moments, making it popular among fitness enthusiasts.

[0003] In the existing technology, the traditional door-mounted horizontal bar structure can refer to the telescopic horizontal bar disclosed in CN202740676U. The installation process of the existing door-mounted horizontal bar lacks feedback. Users can only test the installation strength by applying simple force during installation, and cannot determine whether the horizontal bar will fall off during subsequent use, resulting in safety hazards in the use of the door-mounted horizontal bar.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

Detailed Implementation

[0040] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] In the existing technology, the traditional door-mounted horizontal bar structure can refer to the telescopic horizontal bar disclosed in CN202740676U. The installation process of the existing door-mounted horizontal bar lacks feedback. Users can only test the installation strength by applying simple force during installation, and cannot determine whether the horizontal bar will fall off during subsequent use, resulting in safety hazards in the use of the door-mounted horizontal bar.

[0044] Based on the aforementioned problems in the existing technology, this utility model provides a telescopic rod locking indicator mechanism, such as... Figure 1 As shown, the telescopic rod locking and prompting mechanism includes: a main rod 100, an adjusting rod 200, and a prompting component 300. The adjusting rod 200 is connected to one end of the main rod 100 by a lead screw. The prompting component 300 includes a base 310 and a rotating component 320. The base 310 is fixedly connected to the main rod 100 to rotate synchronously with the main rod 100. The rotating component 320 is mounted on the base 310. One of the base 310 and the rotating component 320 has a plurality of resistance grooves 312 on its surface, and the other has a directional elastic component 321. The elastic component 321 is arranged to press against the resistance grooves 312. When the torque applied to the rotating component 320 exceeds the preset resistance, the elastic component 321 undergoes elastic deformation and slides into the adjacent resistance groove 312 along the rotation direction.

[0045] This invention allows the main rod 100 to rotate by gripping the rotating component 320, forming a relative rotational extension length with the adjusting rod 200. When the end of the adjusting rod 200 is subjected to a predetermined pressure, the base 310 connecting the main rod 100 can no longer rotate. At this time, the user continues to apply force to the rotating component 320, causing the torque to exceed the resistance of the resistance groove 312 to the elastic component. This causes the elastic component 321 to undergo elastic deformation and slide into the adjacent resistance groove 312 along the rotation direction. During this process, the operating feel and sound change, providing the user with an indication of the installation status, ensuring that the installation strength of the single bar reaches the predetermined strength, and improving safety during use.

[0046] In the above embodiments, such as Figure 1 and Figure 2As shown, the main body of the telescopic rod locking reminder mechanism of this utility model consists of a main rod 100, an adjusting rod 200, and a reminder component 300. The main rod 100 and the adjusting rod 200 are connected by a lead screw. By controlling the relative rotation of the main rod 100 and the adjusting rod 200, the relative position of the main rod 100 and the adjusting rod 200 can be adjusted to form different states of extension or retraction. In this utility model, when the telescopic rod structure is applied to a single bar on a door, the locking state refers to the state in which the main rod 100 and the adjusting rod 200 are extended to a predetermined length and abut against the two sides of the door frame. In this locking state, the main rod 100 and the adjusting rod 200 are subjected to design pressure, which can maintain the stability of the abutment without generating pressure on the lead screw in the main rod 100 and the adjusting rod 200 that exceeds the design strength, so as to prevent damage to the lead screw structure due to excessive pressure.

[0047] Specifically, the aforementioned prompting component 300 includes a base 310 and a rotating component 320. The base 310 is fixedly connected to the main rod 100. When the base 310 is driven to rotate, the main rod 100 rotates synchronously. In one specific embodiment, a plurality of resistance grooves 312 are provided on the base 310. Correspondingly, the rotating component 320 is rotatably positioned on the main rod 100. The rotating component 320 includes an oriented elastic component 321. The elastic component 321 is positioned toward the resistance groove 312 and is pressed against the resistance groove 312.

[0048] In actual use, the user holds the rotating component 320 and rotates it. Because the elastic component 321 is engaged in the resistance groove 312, and the end of the adjusting rod 200 away from the main rod 100 is not subjected to a predetermined pressure, the elastic component 321 drives the resistance groove 312 to rotate, which in turn drives the main rod 100 to rotate, creating a relative rotation with the adjusting rod 200, thus achieving the effect of adjusting the length of the telescopic rod. When the end of the adjusting rod 200 is subjected to a predetermined pressure, a predetermined lateral pressure is formed on the thread in the lead screw structure. At this time, when the user continues to rotate the rotating component 320, the main rod 100 is restricted and cannot continue to rotate. With the resistance groove 312 fixed, the elastic component 321 is squeezed against the side wall of the resistance groove 312, causing the elastic component 321 to elastically deform and eventually pass through the resistance groove 312 into the next resistance groove 312. During the process, a crisp sound is generated due to the elastic reset impact, which serves as a reminder to the user. In this state, the telescopic rod is locked, and no matter how the user rotates the elastic component 321, it will not cause relative rotation between the main rod 100 and the adjusting rod 200. Therefore, it can avoid the user applying excessive force, prevent the thread structure from stripping or being damaged, and improve the service life and reliability of the door bar.

[0049] In another possible implementation, the resistance groove 312 can also be provided on the rotating member 320, and correspondingly, the elastic component 321 should be provided on the disc body 311 to achieve the same structural correspondence as the above-mentioned motion process.

[0050] Furthermore, in one possible embodiment of this utility model, such as Figure 1 and Figure 5 As shown, the base 310 includes a disc 311 that protrudes circumferentially from the outer wall of the base 310. The disc 311 is preferably integrally formed with the base 310, or is securely connected using a robust structure. A plurality of resistance grooves 312 are arranged in a circumferential array on one side of the disc 311 corresponding to the rotating member 320, for correspondence with the elastic component 321 disposed on the rotating member 320. Furthermore, the elastic component 321 specifically consists of a compression spring 322 and a contact member 323. The elastic curve of the compression spring 322 is preset to control the interaction between the adjusting rod 200 and the door. The pressure strength of the frame, the contact 323 is the part that actually contacts the resistance groove 312. At the same time, the shape of the contact 323 should match the resistance groove 312 so that the contact 323 can be firmly locked in the resistance groove 312 by the elastic compression of the compression spring 322, and when the radial force applied by the user to the rotating part 320 exceeds a certain range, it can reverse the compression spring 322 to break away from the current resistance groove 312 and enter the next resistance groove 312, so as to achieve the effect of impacting the next resistance groove 312 when elastically reset, and form feedback prompts through sound and operation touch.

[0051] In this embodiment, the above-mentioned structural design not only ensures the accuracy of the user's operation during the installation process, but also improves the user experience. When the user feels a certain resistance and hears a crisp sound, he can determine that the bar on the door has reached the predetermined locking state, and there is no need to apply excessive force.

[0052] Furthermore, such as Figure 5 and Figure 6As shown, in a specific embodiment of this utility model, the resistance groove 312 includes at least a first guide surface 312a and a second guide surface 312b arranged opposite to each other. The relative angle between the first guide surface 312a and the disc body 311 should be greater than the relative angle between the second guide surface 312b and the disc body 311. Specifically, a plane may also be provided between the first guide surface 312a and the second guide surface 312b within the resistance groove 312. This application does not limit this. The purpose of the structural arrangement in the resistance groove 312 is to form a stable engagement of the contact member 323 within a certain force range. In this embodiment, the angle of the first guide surface 312a is greater than the angle of the second guide surface 312b. The first guide surface 312a is located on the side corresponding to the radial direction in which the telescopic rod extends when the user rotates the main rod 100, thereby allowing the first guide surface 312a to pass through. The slope of 12a limits the contact 323. Before the adjusting rod 200 forms a predetermined contact with the door frame, the first guide surface 312a locks the contact 323 in the corresponding resistance groove 312 to ensure that the main rod 100 rotates synchronously when the user rotates the rotating part 320. After the adjusting rod 200 forms a predetermined contact with the door frame, when the user continues to rotate the rotating part 320, since the main rod 100 no longer rotates, the first guide surface 312a guides the contact 323. The slope of the first guide surface 312a exerts a component force on the contact 323 that compresses the compression spring 322, causing the compression spring 322 to compress. During this process, the contact 323 moves relative to the first guide surface 312a until the contact 323 disengages from the first guide surface 312a and enters the next resistance groove 312, thus completing the reminder function.

[0053] In this embodiment, as Figure 6 As shown, the first guide surface 312a is located on the side corresponding to the radial direction in which the telescopic rod extends when the user rotates the main rod 100, and the second guide surface 312b is located on the side corresponding to the radial direction in which the telescopic rod retracts when the user rotates the main rod 100. Therefore, to avoid the main rod 100 rotating in the opposite direction due to user misoperation, causing the telescopic rod to retract and creating a safety risk during use, in this embodiment, the angle of the second guide surface 312b is set to be smaller than the angle of the first guide surface 312a. This ensures that when the rotating component 320 rotates in the opposite direction, the elastic component 321 can easily pass over the second guide surface 312b. In other words, there is no locking or limiting effect of the second guide surface 312b on the elastic component 321 during the process. This ensures that the operation process will not cause relative rotation between the main rod 100 and the adjusting rod 200, nor will it affect the installation state of the single bar on the door, thereby ensuring the safety of the user during installation and use.

[0054] On the other hand, in order to ensure that the contact 323 cooperates with the first guide surface 312a and the second guide surface 312b, in this embodiment, the contact 323 should be set along a predetermined arc. Specifically, the contact 323 can be set as a spherical or elliptical shape, etc., and its surface arc should adapt to the slope of the first guide surface 312a and the second guide surface 312b in the resistance groove 312 to ensure that the contact 323 slides stably in the first guide surface 312a and the second guide surface 312b. In addition, the material of the contact 323 should be selected with a certain hardness and wear resistance, such as stainless steel or hard plastic. Correspondingly, the material of the disc 311 should be compatible with the material selected for the contact 323 so that the contact 323 can produce a crisp sound when it enters the next resistance groove 312, so as to ensure that the prompting function is clearly displayed and improve the service life and stability of the contact 323.

[0055] Furthermore, in another possible embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the aforementioned rotating component 320 is rotatably mounted on the base 310. The rotating component 320 has several mounting holes 325 on the side facing the disc 311. These mounting holes 325 are used to install multiple elastic components 321. In this embodiment, multiple elastic components 321 can be simultaneously mounted on the rotating component 320 to achieve the aforementioned driving of the main rod 100 and the function of reminding the user. Specifically, the elastic component 321 includes a compression spring 322 and a contact member 323. The compression spring 322 is slidably mounted within the mounting hole 325, with one end limited by the bottom of the mounting hole 325. The contact member 323 is partially mounted within the mounting hole 325, pressing against the other end of the compression spring 322, causing the compression spring 322 to be in a compressed state. The portion of the contact member outside the mounting hole 325 is located within the resistance groove 312, thus achieving the aforementioned driving rotation and groove-crossing reminder functions.

[0056] In practical applications, the aforementioned multiple mounting slots are evenly arranged radially along the rotating component 320 to ensure that each elastic component 321 is subjected to uniform force during rotation, thereby improving rotational stability and balance. Simultaneously, this design also increases the reliability and durability of the support component 300, ensuring it maintains good working condition even after prolonged use. Furthermore, the design of the mounting holes 325 facilitates the installation and replacement of the elastic components 321, reducing maintenance costs.

[0057] In another possible embodiment of this utility model, in order to achieve the goal of aligning the rotating member 320 with the disk body 311 at a predetermined distance and allowing the rotating member 320 to rotate freely, as follows: Figure 1 and Figure 2As shown, the aforementioned prompting component 300 also includes an annular cover 330. An annular baffle structure is provided on one side of the annular cover 330. The annular cover 330 is used to limit the rotation component 320 and the disc body 311. Specifically, in this embodiment, the rotation component 320 also includes a shaft wheel 324 fixed to one end. The shaft wheel 324 is integrally formed with the rotation component 320, and its diameter is adapted to the diameter of the disc body 311 (the diameter of the shaft wheel 324 is the same as or slightly smaller than the diameter of the disc body 311). During actual installation, the annular cover 330 moves along the rotation component 320... The upper shaft wheel 324 is fitted onto the opposite side, and after the shaft wheel 324 is fitted, the disc body 311 is further fitted onto it. It is then fixedly connected to the outer wall of the disc body 311 by a fixing structure such as screws. The inside of the annular cover 330 is smooth. Under this installation structure, the shaft wheel 324 is restricted to a position close to the disc body 311. On the one hand, this can prevent the contact 323 located in the mounting hole 325 from falling off. On the other hand, it can compress the compression spring 322 with a predetermined pressure, so that the pressure of the compression spring 322 on the contact 323 is matched with the pressure required for the contact 323 to engage in the resistance groove 312 and drive the disc body 311 to rotate.

[0058] Meanwhile, the axle wheel 324 rotates freely within the annular cover 330. Since the rotating part 320 is rotatably mounted on the base 310, the contact part 323 can be used to indicate that the telescopic rod is in the locked (extended and abutting at the predetermined position) state and the contact part 323 passes through the resistance groove 312 and enters the next resistance groove 312.

[0059] Furthermore, such as Figure 1 and Figure 5 As shown, a plurality of clearance grooves 313 are evenly provided on the base 310 at the position corresponding to the rotating member 320. The clearance grooves 313 are arranged radially around the circumference. The arrangement of the clearance grooves 313 reduces the contact area between the base 310 and the rotating member 320, thereby reducing the friction between the rotating member 320 and the base 310. This avoids the situation where the frictional resistance between the rotating member 320 and the base 310 affects the relative rotation between the rotating member 320 and the base 310, causing the aforementioned prompting component 300 to fail.

[0060] In one possible embodiment of this utility model, to ensure the driving effect of the base 310 on the main rod 100, the base 310 can be integrally formed and mounted on the main rod 100 during actual production; in another possible embodiment of this utility model, such as Figure 1 and Figure 5As shown, the base 310 and the main rod 100 can be separate components to facilitate user replacement of functional parts. Specifically, the base 310 is fitted onto one end of the main rod 100 and can be fixedly connected by snap-fit, adhesive, screws, or other fixing structures. To prevent relative rotation between the base 310 and the main rod 100, a notch 110 is provided at the corresponding end of the main rod 100 in this embodiment. Correspondingly, a tenon 315 is provided on the inner side of the base 310. During actual assembly, the tenon 315 fits into the notch 110, thereby forming a radial engagement between the main rod 100 and the base 310 to restrict rotation of the base 310 relative to the main rod 100. This structural design not only improves assembly efficiency and error prevention but also ensures a stable connection between the base 310 and the main rod 100 during use, thus guaranteeing the stability and reliability of the telescopic rod locking indicator mechanism.

[0061] In another possible embodiment of this utility model, such as Figure 2 and Figure 3 As shown, in order to lock the relative distance between the main rod 100 and the adjusting rod 200 in the telescopic rod after adjustment, in addition to preventing the user from over-twisting and preventing the telescopic rod from retracting due to misoperation through the above-mentioned prompting mechanism, the prompting mechanism in this embodiment also includes a locking structure. This structure is specifically composed of an extension 314 provided on the base 310 facing the adjusting rod 200 side and a locking member 340 detachably provided on the extension 314. The extension 314 and the base 310 are preferably made in one piece to prevent the relative rotation between the extension 314 and the base 310 from affecting the locking effect. The extension 314 is specifically a ring structure, and the locking member 340 is fitted onto the extension 314. In practical use, the locking member 340 has two states. When the user needs to adjust the length of the telescopic rod, the locking member 340 is separated from the extension 314. At this time, the locking member 340 is fitted onto the adjusting rod 200 and can move freely along the length direction of the adjusting rod 200. When the user needs to lock the length of the telescopic rod, the locking member 340 is fitted onto a predetermined position on the extension 314. At this time, the locking member 340 and the adjusting rod 200 are engaged, and the position of the adjusting rod 200 is locked by pressure.

[0062] Specifically, the locking member 340 consists of a sleeve 341 fitted on the outer side of the extension 314 and a plurality of tenons 342 integrally formed with the sleeve 341 and disposed on the inner side of the sleeve 341. The tenons 342 are spaced a certain distance from the corresponding surfaces of the sleeve 341. When the locking member 340 is combined with the extension 314, the tenons 342 are inserted into the inner side of the extension 314 and clamp the extension 314 with the sleeve 341 fitted on the outer side of the extension 314 to achieve the installation and fixing effect. At the same time, in this state, the tenons 342 form an interference fit with the outer wall of the adjusting rod 200, thereby locking the adjusting rod 200 by increasing the friction.

[0063] In another embodiment of this utility model, a tenon structure can be provided on the tenon 342, and a corresponding slot structure can be provided on the outer side wall of the adjusting rod 200. After the locking member 340 is installed, the rotation can be restricted by the cooperation of the tenon and the slot.

[0064] Based on the above embodiments, such as Figure 3 and Figure 6 As shown, the working principle of the telescopic rod locking reminder mechanism of this utility model is as follows:

[0065] When the user installs the telescopic rod, the user first makes a rough adjustment to the relative distance between the main rod 100 and the adjusting rod 200 in the telescopic rod so that the end of the adjusting rod 200 forms a contact state with the door frame with a certain friction force.

[0066] Before the adjusting rod 200 forms a predetermined contact with the door frame, the user can extend the main rod 100 and the adjusting rod 200 further by rotating the rotating component 320. During the process, the first guide surface 312a locks the contact component 323 in the corresponding resistance groove 312 to ensure that the main rod 100 rotates synchronously when the user rotates the rotating component 320.

[0067] After the adjusting rod 200 forms a predetermined contact with the door frame, when the user continues to rotate the rotating part 320, since the main rod 100 no longer rotates, the first guide surface 312a guides the contact part 323. The slope of the first guide surface 312a exerts a component force on the contact part 323 that compresses the compression spring 322, causing the compression spring 322 to compress. During this process, the contact part 323 moves relative to the first guide surface 312a until the contact part 323 disengages from the first guide surface 312a and enters the next resistance groove 312, thus completing the reminder function.

[0068] Based on the above embodiments, this utility model also provides a door-mounted horizontal bar, which includes the telescopic rod locking and reminder mechanism described in the above embodiments, such as... Figure 1 and Figure 2As shown, the telescopic rod locking reminder mechanism includes: a main rod 100, an adjusting rod 200 connected to one end of the main rod 100 by a lead screw, and a reminder component 300 disposed on the main rod 100; the reminder component 300 includes a base 310 and a rotating component 320, the base 310 is fixedly connected to the main rod 100 and includes a plurality of resistance grooves 312, the rotating component 320 is positioned and rotatably disposed and includes an oriented elastic component 321, the elastic component 321 is disposed to press against the resistance grooves 312.

[0069] Furthermore, such as Figure 7 As shown, the main rod 100 is mirror-equipped with an adjustment rod 200 and a prompting component 300 at both ends. Furthermore, foot supports 400 are respectively provided at the ends of the adjustment rods 200 located at both ends of the main rod 100. The foot supports 400 are used to actually contact the door frame, so as to increase the contact area and improve the installation stability.

[0070] This invention allows the main rod 100 to rotate by gripping the rotating component 320, creating a relative rotational extension length with the adjusting rod 200. When the end of the adjusting rod 200 is subjected to a predetermined pressure, the base 310 connecting the main rod 100 can no longer rotate. At this point, if the user continues to apply force to the rotating component 320, the applied torque will exceed the resistance of the resistance groove 312 to the elastic component, causing the elastic component 321 to undergo elastic deformation and slide into the adjacent resistance groove 312 along the rotation direction. During this process, the operating feel and sound change, providing the user with an indication of the installation status and ensuring that the bar installation strength reaches the predetermined strength, thus improving safety. In addition, the above structural design can also prevent the user from applying excessive force, preventing problems such as stripping or damage to the threaded structure, and improving the service life and reliability of the bar on the door.

[0071] In summary, this utility model provides a telescopic rod locking reminder mechanism and a door bar. The telescopic rod locking reminder mechanism includes a main rod, an adjusting rod, and a reminder component. The adjusting rod is connected to one end of the main rod by a lead screw. The reminder component includes a base and a rotating component. The base is fixedly connected to the main rod to rotate synchronously with the main rod, and the rotating component is mounted on the base. One of the base and the rotating component has several resistance grooves on its surface, and the other has a directional elastic component that presses against the resistance grooves. When the torque applied to the rotating component exceeds the preset resistance, the elastic component undergoes elastic deformation and slides into the adjacent resistance groove along the rotation direction. This invention allows the main rod to rotate by gripping the rotating component, creating a relative rotational extension length with the adjusting rod. When a predetermined pressure is applied to the end of the adjusting rod, the base connecting the main rod cannot continue to rotate. At this point, the user continues to apply force to the rotating component, causing the torque to exceed the resistance of the resistance groove to the elastic component. This causes the elastic component to elastically deform and slide into the adjacent resistance groove along the rotation direction. During this process, the operating feel and sound change, providing the user with an indication of the installation status and ensuring that the single bar installation strength reaches the predetermined strength, thus improving safety. It should be understood that the application of this invention is not limited to the examples described above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
