Description

Technical Field

[0001] This utility model relates to a stool, specifically a stool with a movable function. Background Technology

[0002] Traditional children's stools are mostly fixed designs (such as wooden or plastic stools), which only meet the needs of sitting and lying down and lack interactivity and movement functions, making it difficult to stimulate children's interest in exploration. Therefore, wheels are designed under the stools to assist in moving the stools and improve children's interest in exploration.

[0003] Currently available rolling stools suffer from two technical drawbacks in practical use due to deficiencies in their support structure design: First, limited by conventional structural design, the force transmission path is concentrated at the wheel connection point when the stool is under load. Lacking an effective stress dispersion mechanism, this area is prone to significant stress concentration, directly affecting the product's load-bearing capacity. Second, the clearance structure design of the wheel moving parts fails to effectively consider dust prevention requirements, easily accumulating foreign objects in complex usage environments, leading to rolling resistance and significantly reducing the smoothness and reliability of the device's movement. Therefore, this utility model provides a stool with a moving function to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1In this embodiment of the utility model, a stool with a movable function includes a stool body 10 and a movable component. The four corners of the bottom of the stool body 10 are fixedly connected to mounting brackets 12 for connection. Support components for supporting the stool body 10 are installed on the two side walls of the mounting brackets 12. The support components can disperse the stress on the stool body 10 to the support components, thereby improving the load-bearing capacity of the stool body 10. The movable component is installed at the bottom of the mounting brackets 12. Specifically, the bottom of the stool body 10 is fixedly connected to a reinforcing rib 11 for improving the load-bearing capacity of the stool body 10. The reinforcing rib 11 is rectangular in the middle and extends to the two ends and four corners. The reinforcing rib 11 extends through the four corners to the movable component. Through the design of the reinforcing rib 11, the pressure on the stool body 10 can be dispersed to all parts of the stool body 10, avoiding the concentrated pressure on the stool body 10 from causing damage.

[0024] See Figure 2 The moving component includes wheels 20, a housing 21, and a steering rod 22. A rotating shaft is installed at the axis of the wheels 20 for movement. The wheels 20 are rotatably connected to the inner wall of the housing 21 through the rotating shaft. The steering rod 22 for adjusting the direction of travel is rotatably connected to the top of the housing 21. When moving, the bench body 10 can be moved by the rotation of the wheels 20, and the orientation of the wheels 20 can be adjusted by the rotation of the steering rod 22. The wheels 20 can move in different directions.

[0025] The mounting bracket 12 is equipped with a connecting assembly for limiting the steering rod 22. The connecting assembly includes a mounting plate 31 that is bolted to the mounting bracket 12 and a mounting seat 30 that is fixedly connected to the bottom of the mounting plate 31. The mounting bracket 12 has a slot for mating installation. The mounting plate 31 is adapted to the slot. The steering rod 22 is installed at the axial position of the mounting seat 30. The bottom and top of the mounting seat 30 are both provided with a through hole. The steering rod 22 passes through the first through hole at the bottom end of the mounting seat 30. The bottom moving assembly can be installed in the mounting bracket 12 by the cooperation of the mounting seat 30 and the mounting plate 31.

[0026] See Figure 3 A rotating assembly for assisting the rotation of the steering rod 22 is installed in the middle of the inner wall of the mounting base 30. The rotating assembly is designed to assist the rotation of the steering rod 22 and avoid excessive resistance that would affect its rotation stability. A cleaning assembly for cleaning the steering rod 22 is installed at the bottom of the inner wall of the mounting base 30. The cleaning assembly is used to clean the impurities carried on the steering rod 22 and avoid impurities causing the steering rod 22 to jam and affect its rotation stability.

[0027] The mounting plate 31 contains an adjustment component for adjusting the drive support assembly. The position of the support assembly can be adjusted to different ranges to adapt to different pressures.

[0028] See Figure 4 The rotating assembly includes a rotating disk 50, a mounting rod 51, and ball bearings 53. The mounting rod 51 is fixedly connected to the top axis of the rotating disk 50. The mounting rod 51 has a hollow structure and communicates with the first through hole at the bottom of the mounting base 30. The rotating disk 50 is rotatably connected to the bottom end of the mounting rod 51. The steering rod 22 passes through the rotating disk 50 and is slidably connected to the inner wall of the mounting rod 51. A ring-shaped fixing ring 52 is fixedly connected to the inner wall of the mounting base 30 at the bottom of the rotating disk 50. A ring-shaped rotating groove is formed on the wall surface opposite to the fixing ring 52 and the rotating disk 50. The inner wall of the rotating groove is rotatably connected to the ball bearings 53. The outer walls on both sides of the steering rod 22 are provided with a first sliding groove. A protrusion 54 is fixedly connected to the inner ring of the rotating disk 50. The protrusion 54 is slidably connected to the inner wall of the first groove. When the steering rod 22 slides, it can slide along the inner wall of the mounting rod 51 to guide the sliding direction of the steering rod 22, so as to avoid its deviation and affect the stability of the movement of the wheel 20 at the bottom. When the orientation of the steering rod 22 changes, the steering rod 22 rotates, and the steering rod 22 can drive the rotating disk 50 to rotate through the protrusion 54. Then, it rotates on the fixed ring 52 through the ball bearing 53. The ball bearing 53 reduces the friction generated during rotation and avoids friction causing the steering rod 22 to jam and affect the change of the movement direction of the wheel 20.

[0029] See Figure 3 The support assembly includes a support plate 40 and an adjusting plate 41. The mounting frame 12 has a second sliding groove at both ends. The adjusting plate 41 is slidably connected to the inner wall of the second sliding groove. The support plate 40 is fixedly connected to the tail end of the adjusting plate 41. The top of the support plate 40 is in contact with the bottom of the bench body 10. When the bench body 10 is subjected to pressure, the pressure can be transmitted to the mounting frame 12 at the top through the four wheels 20. At this time, the support plate 40 can expand the area of ​​the mounting frame 12 that bears the load on the bench body 10. Under the same pressure, the pressure is reduced and the load-bearing capacity of the bench body 10 is improved.

[0030] See Figure 6 The support assembly also includes a second telescopic rod 47 and a first rotating seat 48. The first rotating seat 48 is fixedly connected to the outer wall of the mounting frame 12 and located at both ends of the adjusting plate 41. Both ends of the support plate 40 are provided with rotating slots. The two ends of the second telescopic rod 47 are respectively rotatably connected to the inner walls of the rotating slots on the first rotating seat 48 and the support plate 40. When the support plate 40 moves, it can drive the second telescopic rod 47 to stretch and rotate synchronously. At this time, the stress on the support plate 40 can be transmitted to the first rotating seat 48 through the second telescopic rod 47, further dispersing the stress borne by the support plate 40 and improving the load-bearing capacity of the bench body 10.

[0031] See Figure 3The adjustment assembly includes a connecting block 43 and a steel plate 44. An adjustment groove is formed on the inner wall of the mounting plate 31. A first telescopic rod 42 is fixedly connected to the top inner wall of the adjustment groove. The connecting block 43 is fixedly connected to the bottom end of the first telescopic rod 42. A second through hole, communicating with the first through hole on the mounting base 30, is formed at the bottom end of the adjustment groove. The steel plate 44 is fixedly connected to both ends of the connecting block 43 and contacts the other side of the adjustment groove. Third sliding grooves are formed on both sides of the adjustment groove on the mounting plate 31. A sliding plate 45 is slidably connected to the inner wall of the third sliding groove. The steel plate 44 is made of nickel-titanium alloy and contacts the sliding plate 45. A transmission rod 46 is fixedly connected to the wall opposite to the sliding plate 45 and the adjustment plate 41. Sliding holes are formed at both ends of the adjustment groove. The transmission rod 46 is slidably connected to the inner wall of the sliding hole. A return spring is fixedly connected to the wall opposite to the sliding plate 45 and the adjustment groove. The return spring is sleeved on the outer wall of the transmission rod 46. When the user... When a person sits on the bench body 10, the pressure is transmitted to the wheels 20 at the bottom and drives the steering rod 22 to slide within the mounting rod 51 via the outer casing 21. When the steering rod 22 slides into the adjustment groove, it can squeeze the connecting block 43. The connecting block 43, when squeezed, moves along the extension and retraction direction of the first telescopic rod 42, and causes the steel plate 44 to deform and expand outward. At this time, the pressure on the sliding plate 45 is squeezed through the transmission rod 46 to squeeze the adjustment plate 41, thereby adjusting the position of the support plate 40. When the pressure on the bench body 10 changes, the pressure on the steel plate 44 changes synchronously, and the position of the support plate 40 changes accordingly. The support plate 40 can be moved a different distance according to the pressure it bears, further expanding the bearing area, reducing the pressure, and improving the bearing effect of the bench body 10. When the bench body 10 is not in use, it can be reset by the deformation of the steel plate 44 and the return spring.

[0032] See Figure 5 The cleaning assembly includes a connecting rod 60 and a cleaning block 61. The bottom inner wall of the mounting base 30 has multiple fourth sliding grooves arranged in a circular pattern at the first through hole. A sliding block 63 is slidably connected to the inner wall of each fourth sliding groove. A fixed plate 23 is fixedly connected to the middle position of the outer wall of the steering rod 22. The connecting rod 60 is rotatably connected to the wall surfaces opposite the fixed plate 23 and the sliding block 63. A second rotating seat 62 is fixedly connected to the wall surfaces opposite the fixed plate 23 and the sliding block 63. Rotating pins are rotatably connected to both ends of the connecting rod 60, and the rotating pins are fixedly connected to the second rotating seat 62. The cleaning block 61 is fixedly connected to the sliding block 63 on the side near the steering rod 22 on the inner wall of the rotating seat 62. The cleaning block 61 is equipped with bristles on the side away from the sliding block 63. When the steering rod 22 moves upward, the fixed plate 23 moves upward at the same time, which can drive the second rotating seat 62 on it to move upward, and then drive the connecting rotating rod 60 inside it to rotate. The connecting rotating rod 60 can drive the sliding block 63 to slide in the fourth sliding groove and approach the steering rod 22 through the second rotating seat 62 at the other end, so that the bristles on the cleaning block 61 are attached to the outer wall of the steering rod 22 for cleaning.

[0033] The working principle of this utility model is as follows: When it is necessary to ride, the user sits on the top of the bench body 10. At this time, under the pressure of the user's weight, the steering rod 22 is driven to slide in the mounting rod 51, so that the wheel 20 can rotate to move forward and the steering rod 22 can rotate to turn. When the steering rod 22 rotates, the ball bearings 53 on the rotating disk 50 can slide on the top of the fixed ring 52 through the protrusion 54, thereby reducing the friction during rotation.

[0034] When the steering rod 22 moves, it can press the connecting block 43 upward and drive the steel plate 44 to deform and press the sliding plate 45. It can also press the adjusting plate 41 through the transmission rod 46, causing the adjusting plate 41 and the support plate 40 to move outward, increasing the bearing area, reducing the pressure, increasing the bearing capacity of the bench body 10, and dynamically adjusting the outward displacement of the support plate 40 according to the weight of the user.

[0035] When the steering rod 22 moves, the cleaning block 61 can be driven to approach the outer wall of the steering rod 22 through the connecting rotating rod 60, and the bristles on it can clean the outer wall of the steering rod 22.

[0036] When in use, this utility model, through the set adjustment component and support component, can expand the support area according to the user's weight, reduce the pressure on the bench body 10 when subjected to pressure, distribute the load on the bench body 10, and improve its load-bearing capacity.

[0037] The cleaning components can clean the steering rod 22, preventing impurities on the steering rod 22 from being brought into the mounting base 30, which could cause the steering rod 22 to jam and affect its rotation, thereby affecting the steering of the wheel 20 and the smoothness of its movement.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
