Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0057] The present invention will be further described below in conjunction with the embodiments.

[0058] Example

[0059] See also Figure 1-Figure 7 The present invention provides a technical solution: a static loading testing machine for fitness equipment, including a machine base 1, a bearing platform 2, a protection component 3, and a loading component 4.

The skateboard B5 is slidably connected to the outside of the slider 43. A hanging plate 51 is fixedly provided on the top of the skateboard B5, and a support plate 52 is fixedly provided at the bottom of the skateboard B5. An installation shaft 53 for installing the barbell plate 100 is fixedly provided on the outside of the support plate 52.

[0065] Furthermore, in order to facilitate the cleaning of the broken pieces of the barbell plate 100, a support seat 22 is rotatably installed on the side of the bottom of the supporting platform 2 away from the side panel A11. The support seat 22 is fixedly arranged on the top of the machine base 1, and the supporting platform 2 rotates upward under the drive of the loading assembly 4.

[0066] On the basis of the above solution, the loading assembly 4 further includes a vertical plate 45 and an elastic wedge block 46 .

[0067] The vertical plate 45 is fixed on the outside of the slider 43 , and is located on the side of the bearing platform 2 close to the side plate A11 ; the elastic wedge block 46 is slidably arranged on the inside of the vertical plate 45 , and the wedge end of the elastic wedge block 46 is arranged close to the bearing platform 2 .

[0068] A mounting groove is formed on one side of the support platform 2 close to the vertical plate 45 , and a slide seat 23 is fixedly disposed inside the mounting groove. The slide seat 23 is in sliding contact with the elastic wedge block 46 .

[0069] On the basis of the above scheme, in order to facilitate the collection and processing of the barbell plate 100 fragments, a storage box 13 for collecting the barbell plate 100 fragments is fixedly provided on the side of the base 1 away from the side panel A11. The storage box 13 is fixedly connected to the base 1 through a baffle 14, and a box door 15 is movably installed on one side of the storage box 13.

[0070] On the basis of the above solution, in order to clean up the barbell plate 100 fragments inside the protection component 3, the protection component 3 also includes a side panel B33, a front guard plate 34 and a counterweight block 36.

[0071] The side panel B33 serves as the opposite side of the side frame 31 in the cylindrical protective structure, and the side panel B33 is located in the end face direction of the barbell plate 100; the front guard plate 34 is located on the side of the side panel B33 away from the side panel A11, and the top of the front guard plate 34 is rotatably connected to the side frame 31 and the side panel B33 through the rotating shaft 35; the counterweight block 36 is used to drive the front guard plate 34 to open and close automatically, and the counterweight block 36 is fixedly installed at the bottom of the front guard plate 34.

[0072] On the basis of the above scheme, in order to ensure the integrity of the cylindrical protection structure of the protection component 3, the protection component 3 further includes a rear guard plate 37, which is located on the side of the side plate B33 away from the front guard plate 34, and the rear guard plate 37 is fixedly arranged on the outer side of the slider 43;

[0073] On the basis of the above scheme, plate holes 21 are opened on the inner sides of the bearing platform 2 and the supporting seat 22 corresponding to the rear guard plate 37. Specifically, in order to ensure that the barbell plate 100 can be sealed to the cylindrical protective structure by the rear guard plate 37 before loading, when installing the barbell plate 100 with the largest diameter, the distance between the top of the barbell plate 100 and the loading block 44 is greater than the distance between the bottom of the barbell plate 100 and the bottom of the rear guard plate 37. That is, when the bottom of the barbell plate 100 contacts the top of the bearing platform 2, as the slider 43 drives the loading block 44 to approach the top of the barbell plate 100, the slider 43 will synchronously drive the rear guard plate 37 to approach the top of the bearing platform 2, so that the rear guard plate 37 is first contacted and sealed with the bearing platform 2, and finally the loading experiment is carried out. When the diameter of the installed barbell plate 100 decreases, the distance between the top of the barbell plate 100 and the loading block 44 increases, while the distance between the bottom of the barbell plate 100 and the rear guard plate 37 decreases, which can meet the requirement of closing the protective component 3 before the experiment.

[0074] On the basis of the above scheme, in order to prevent the supporting platform 2 from colliding with the supporting seat 22 after separating from the elastic wedge block 46, a buffer assembly 16 is symmetrically fixed on the top of the base 1. The buffer assembly 16 includes a rubber pad that contacts the bottom of the supporting platform 2. Specifically, the buffer assembly 16 also includes an elastic telescopic rod installed at the bottom of the rubber pad and a sleeve slidably installed on the outside of the elastic telescopic rod.

[0075] On the basis of the above solution, the present application also includes a switch assembly 6, which is arranged on the outside of the side frame 31 and is used to drive the slide plate A32 to slide.

[0076] In a specific implementation, the switch assembly 6 includes a rotating plate 61, a sliding hole 62 is opened on the inner side of the rotating plate 61, a sliding pin 38 is slidably arranged on the inner side of the sliding hole 62, the sliding pin 38 is fixedly arranged on the outer side of the slide plate A32, one end of the rotating plate 61 is rotatably arranged on the outer side of the side frame 31, and the rotating plate 61 drives the rotating plate 61 to rotate to open the slide plate A32 when the rear guard plate 37 is reset.

[0077] On the basis of the above solution, the switch assembly 6 further includes a fixed wedge block 63 and a sliding wedge block 65 .

[0078] The fixed wedge block 63 is fixedly set on one end of the rotating plate 61 away from the sliding pin 38; the sliding wedge block 65 is slidably set on the side of the mounting plate 64 close to the fixed wedge block 63, and the mounting plate 64 is fixedly mounted on the outside of the rear guard plate 37 through the connecting plate 39. An elastic member 66 for applying external force to the sliding wedge block 65 is set on the outside of the mounting plate 64.

[0079] refer to Figure 1-Figure 7 The traditional method of testing the compressive performance of barbell plates is usually to apply pressure to the barbell plates for testing. However, when the static pressure exceeds the maximum limit of the barbell plates, the barbell plates may splash, posing a safety hazard to surrounding objects and test operators.

[0080] In order to overcome the above-mentioned defects, the present invention designs a static loading testing machine for fitness equipment.

[0081] Principle and advantages of static loading testing machine:

[0082] First, the loading assembly 4 in the static loading test machine for fitness equipment of the present application applies power to the slider 43 through the hydraulic cylinder 42, so that the slider 43 pushes the loading block 44 to pressurize the barbell plate 100 on the top of the bearing platform 2, thereby achieving a static loading effect, and reflecting the compressive performance of the barbell plate 100 according to the output load of the hydraulic cylinder 42; during the loading process, the barbell plate 100 is protected by the protective assembly 3 on the top of the bearing platform 2 to prevent the pressure on the barbell plate 100 from exceeding the maximum limit and splashing to cause damage to surrounding objects or experimental operators;

[0083] Its advantage is that the barbell plate 100 is protected from splashing by the protective component 3 to prevent damage to surrounding objects or experimenters, and the cylindrical protective structure of the protective component 3 can be opened by a slide plate A32 slidably installed on the inner side of the side frame 31 in the protective component 3, so that the experimenter can take and place the barbell plate 100 inside the protective component 3 to ensure the smooth progress of the loading experiment.

[0084] Experimental method of static loading testing machine:

[0085] First, when the supporting platform 2 is in a horizontal state, the protection component 3 is driven to be in a vertical state. At this time, the side frame 31, the slide plate A32 and the side plate B33 on the top of the supporting platform 2 and the front guard plate 34 rotatably connected to the outside of the side plate B33 are all in a vertical state, and the rear guard plate 37 on the outside of the slider 43 fits on the outside of the side plate B33, and has a certain distance from the top of the supporting platform 2, and the loading component 4 drives the loading block 44 to be located at the highest point, and the elastic wedge block 46 is located above the supporting platform 2; at this time, the loading block 44 is pushed downward by the hydraulic cylinder 42 to drive the installation shaft 53 to reset downward, and the original position of the installation shaft 53 is the position where the maximum diameter barbell plate 100 can be installed, and at the same time, the rear guard plate 37 drives the switch component 6 to automatically drive the slide plate A32 to open the inside of the side frame 31, so that the experimenter can install the barbell plate 100 on the top of the supporting platform 2;

[0086] During installation, align the axial hole of the barbell plate 100 with the installation shaft 53, and install the barbell plate 100 on the outside of the installation shaft 53 in a sleeve manner. The barbell plate 100 is vertically limited below the loading block 44 through the installation shaft 53. When the hydraulic cylinder 42 drives the loading block 44 to move downward, the barbell plate 100 can be driven to approach the top of the bearing platform 2, so that the barbell plate 100 can be vertically installed on the top of the bearing platform 2. At this time, the rear guard plate 37 drives the switch assembly 6 again to automatically close the slide plate A32 to prepare for the loading experiment;

[0087] During the loading experiment, the hydraulic cylinder 42 pushes the slider 43 to slide downward along the right-angle plate 41, so that the slider 43 pushes the loading block 44 to press against the top of the barbell plate 100 to apply static pressure. At this time, the slider 43 drives the outer rear guard plate 37 to be located on the top of the bearing platform 2 or inside the insertion plate hole 21, so as to seal the protective component 3 as a whole; and then the pressure output by the hydraulic cylinder 42 reflects the pressure resistance of the barbell plate 100; if the barbell plate 100 is broken and splashed, the fragments are blocked by the protective component 3 to prevent the splashing of the fragments from causing damage to surrounding objects or experimenters; at the same time, the slider 43 drives the elastic wedge block 46 on the outer side of the vertical plate 45 to slide along the slide seat 23 to the bottom of the bearing platform 2;

[0088] After the experiment, the broken pieces of the barbell plate 100 are located on the top of the bearing platform 2 and on the inner side of the protective assembly 3. When the hydraulic cylinder 42 drives the slider 43 to reset upward, the rear guard plate 37 slides upward to drive the switch assembly 6 to reset, and the slider 43 drives the elastic wedge block 46 to move upward through the vertical plate 45. When the elastic wedge block 46 is located at the bottom of the bearing platform 2, the slider 43 drives the rear guard plate 37 to break away from the inner side of the plate hole 21 and is located above the bearing platform 2. As the slider 43 drives the rear guard plate 37 to continue to rise, the elastic wedge block 46 pushes the bearing platform 2 from bottom to top to rotate on the top of the support seat 22, so that the bearing platform 2 drives the top side frame 31 and side plate B33 to tilt, and the front guard Under the action of the counterweight block 36, the plate 34 rotates around the rotating shaft 35, so that the side of the protective component 3 close to the storage box 13 is opened, and the broken pieces of the barbell plate 100 on the top of the supporting platform 2 can be directly cleaned into the interior of the storage box 13 for collection, until the supporting platform 2 is rotated to a certain angle and disengaged from the elastic wedge block 46. At this time, the supporting platform 2 is automatically reset downward under the action of gravity. During the reset, the supporting platform 2 is supported by the buffer component 16 to prevent the supporting platform 2 from colliding with the support seat 22. Finally, the experimenter directly slides the slide plate A32 to open the protective component 3 again to install the next barbell plate 100 for the experiment. If the barbell plate 100 is not broken, it will not interfere with the normal progress of the experiment.

[0089] It is worth mentioning that the above static loading test method has the following advantages:

[0090] Advantage 1: The hydraulic cylinder 42 drives the slider 43 to rise and fall, so that the slider 43 drives the installation shaft 53 to rise and fall synchronously. When installing the barbell plate 100, the installation shaft 53 is lifted to a high place away from the supporting platform 2, which is convenient for installing barbell plates 100 of different diameters. After the barbell plates 100 of different diameters are installed, they can be limited on the top of the supporting platform 2 under the drive of the slider 43. Then the slider 43 continues to move downward to perform a loading test on the barbell plate 100 after the limit, and the loading test process will not be affected by the installation shaft 53, so that the installation operation of the barbell plate 100 on the top of the supporting platform 2 is more convenient.

[0091] Advantage two, when the slider 43 moves downward to perform the limiting action on the barbell plate 100 after installation, the slider 43 drives the elastic wedge block 46 on the outside of the vertical plate 45 to slide over the slide seat 23 and is located at the bottom of the supporting platform 2. When the slider 43 moves upward to reset, it can drive the elastic wedge block 46 to drag the supporting platform 2 to rotate, so that the supporting platform 2 automatically tilts to clean up the fragments on the top, so as to facilitate the continuous static loading experiment.

[0092] Advantage three, the rear guard plate 37 in the protective component 3 is fixedly installed on the outside of the slider 43, so that the rear guard plate 37 can be lifted and slid under the drive of the slider 43, so that when the rear guard plate 37 closes the cylindrical protective structure of the protective component 3, it will not hinder the lifting and lowering movement of the slider 43 and the vertical plate 45, and the side panel B33 and the side frame 31 will move away from the rear guard plate 37 when following the rotation of the bearing platform 2, and will not affect the rotation of the bearing platform 2 and the side panel B33, so that when the bearing platform 2 is restored to a horizontal state, it drives the side frame 31 and the side panel B33 to automatically align with the rear guard plate 37 to form a cylindrical protective structure.

[0093] Advantage four, the front guard plate 34 located on the outside of the side panel B33 and the side frame 31 will be automatically opened by the counterweight block 36 when the bearing platform 2 rotates and tilts, and the fragments on the inside of the protective component 3 can be automatically cleaned up. When the bearing platform 2 rotates and resets, the front guard plate 34 automatically fits to the outside of the side panel B33 and the side frame 31 under the action of the counterweight block 36, thereby realizing the reorganization of the cylindrical protective structure of the protective component 3.

[0094] Working principle and advantages of switch assembly 6 in static loading testing machine:

[0095] When the hydraulic cylinder 42 drives the loading block 44 and the mounting shaft 53 to move downward to the origin, the rear guard plate 37 drives the sliding wedge block 65 to approach the top of the fixed wedge block 63 through the mounting plate 64, and presses down the fixed wedge block 63 to rotate the rotating plate 61. At this time, the rotating plate 61 moves upward through the sliding pin 38, and then automatically opens the slide plate A32 when the loading block 44 and the mounting shaft 53 are reset. When 100 is installed, the hydraulic cylinder 42 continues to drive the loading block 44 to move downward. At this time, the rear guard plate 37 drives the sliding wedge block 65 on the outside of the mounting plate 64 to continue to move downward along the outside of the fixed wedge block 63 until it is separated from the fixed wedge block 63, so that the slide plate A32 slides downward and resets under the action of its own gravity, without affecting the loading experiment of 100. After the loading experiment is completed, the hydraulic cylinder 42 drives the loading block 44 and the mounting shaft 53 to move downward. The shaft 53 moves upward, and at this time the rear guard plate 37 drives the sliding wedge block 65 to approach the fixed wedge block 63 from bottom to top. When the inclined surface of the sliding wedge block 65 contacts the inclined surface of the fixed wedge block 63, since the fixed wedge block 63 cannot rotate under the restriction of the rotating plate 61, the fixed wedge block 63 squeezes the sliding wedge block 65 until the sliding wedge block 65 is located at the top of the fixed wedge block 63. Then, the sliding wedge block 65 is reset under the action of the elastic member 66. As the hydraulic cylinder 42 drives the loading block 44 and the mounting shaft 53 to move above the origin, the vertical plate 45 drives the bearing platform 2 to start rotating and cleaning through the elastic wedge block 46. At this time, the side frame 31 and the slide plate A32 drive the rotating plate 61 and the fixed wedge block 63 to rotate synchronously. When the bearing platform 2 is reset, the fixed wedge block 63 can be automatically located below the sliding wedge block 65.

[0096] The advantages are that the slide plate A32 can be automatically opened and closed before and after the installation of 100, which reduces the workload of the staff and improves safety; at the same time, the power of the hydraulic cylinder 42 is used to realize the automatic opening and closing of the slide plate A32, which reduces the difficulty of operating the testing machine.
