Technical Field

[0001] The invention belongs to the technical field of sports equipment, and specifically refers to an intelligent pull-up testing device. Background Art

[0002] Pull-ups are a basic method of training the back, upper limbs and trunk strength. They can be performed with only a pair of horizontal bars. They are a common exercise method used by many sports enthusiasts, and are also a common test item in physical fitness tests.

[0003] The existing pull-up intelligent testing device has the following problems:

[0004] The existing intelligent pull-up testing device does not have the ability to adjust the height of the horizontal bar, and cannot be suitable for both tall and short testers. In addition, the traditional intelligent pull-up testing device does not have the ability to protect the tester from slipping, thereby reducing the use efficiency of the intelligent pull-up testing device. Therefore, it cannot meet the existing use requirements of the intelligent pull-up testing device. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present solution provides an intelligent pull-up testing device that can adjust the height of the horizontal bar, is suitable for both tall and short testers, and can protect testers who slip.

[0006] The technical scheme adopted in this scheme is as follows: A pull-up intelligent testing device proposed in this scheme includes a base, a weighing seat, an adjustable pulling mechanism and an anti-fall protection mechanism, the weighing seat is arranged through the inner wall of the base, the adjustable pulling mechanism is arranged at one end of the base, the anti-fall protection mechanism is arranged at the end of the base away from the adjustable pulling mechanism, the adjustable pulling mechanism includes a testing mechanism and a height control mechanism, the testing mechanism is arranged on the upper wall of the base, the height control mechanism is arranged on the testing mechanism, the anti-fall protection mechanism includes a buffer mechanism, a positioning mechanism and an anti-cracking mechanism, the buffer mechanism is arranged on the upper wall of the end of the base away from the testing mechanism, the positioning mechanism is arranged on the buffer mechanism, and the anti-cracking mechanism is arranged on the buffer mechanism on one side of the positioning mechanism.

[0007] As a further preferred embodiment of the present invention, the testing mechanism includes a testing plate, a testing shaft, a testing frame, a pull-up rod and a load-bearing block. The testing plate is symmetrically arranged on the upper wall at one end of the base, and the load-bearing block is arranged on the upper wall of the base between the testing plates. The testing shaft passes through the testing plate and is arranged on the side wall of the load-bearing block. The testing shaft is rotatably arranged on the side wall of the load-bearing block. The testing frame is arranged at one end of the testing shaft close to the testing plate, and the pull-up rod is arranged between one end of the testing frame away from the testing shaft. The height control mechanism includes a guide column, a height control spring, a locking frame, a locking wheel and a locking port. Multiple groups of the guide columns are arranged through the inner wall of the testing plate, the locking frame is arranged on the side of the guide column away from the testing plate, the height control spring is arranged between the test plate and the locking frame on the outside of the guide column, the locking wheel is arranged on the side of the testing shaft away from the load-bearing block, and multiple groups of the locking ports are arranged on the side wall of the locking wheel.

[0008] When in use, the height of the pull-up bar is adjusted according to the height of the person to be tested, and the locking frame is pulled. The locking frame slides along the test plate away from the locking wheel under the action of the elastic deformation of the height control spring, and the locking wheel is turned. The locking wheel drives the test frame to rotate and lift up through the test shaft, and the test frame drives the pull-up bar to rise in height. The locking frame is then released, and the locking frame is inserted into the locking port under the rebound of the height control spring to fix the locking wheel. The test shaft and the locking wheel change from an active state to a fixed state, and the tester grabs the pull-up bar with his hands to perform pull-ups.

[0009] Preferably, the buffer mechanism includes a sliding frame, a buffer plate, a buffer airbag, a retraction spring, an air pump, an air tube and a weighing scale. The sliding frame is slidably arranged on the upper wall of the base away from the test plate. The buffer plate is arranged on the upper wall of the sliding frame. The buffer plate is inclined. The buffer airbag is arranged on the upper wall of the buffer plate. The retraction spring is arranged between the sliding frame and the base. The air pump is arranged on the side of the sliding frame away from the retraction spring. The air tube passes through the buffer plate and is connected between the buffer airbag and the inflation end of the air pump. The weighing scale is arranged on the upper wall of the weighing seat. The positioning mechanism includes a positioning port, a positioning column, a positioning spring and a limit plate , multiple groups of positioning ports are arranged on the upper wall of one end of the base close to the sliding frame, the positioning column is arranged through the inner wall of the sliding frame, the limit plate is arranged on the upper wall of the positioning column, and the positioning spring is arranged between the limit plate on the outside of the positioning column and the sliding frame; the anti-cracking mechanism includes a pressure relief valve, an air supply pump and a ranging sensor, the pressure relief valve is symmetrically arranged on the bottom walls at both ends of the buffer plate, the pressure relief valve passes through the buffer plate and is connected to the buffer airbag, multiple groups of air supply pumps are arranged on the bottom wall of the buffer plate, the inflation end of the air supply pump passes through the buffer plate and is connected to the buffer airbag, multiple groups of ranging sensors are arranged on the bottom wall of the buffer plate, and the ranging end of the ranging sensor passes through the bottom wall of the buffer airbag.

[0010] When in use, the tester who is doing pull-ups has both feet off the ground when holding the pull-up bar with both hands. To prevent the tester from slipping and falling during the exercise, the limit plate is pulled, and the limit plate drives the positioning column away from the upper wall of the base through the deformation of the positioning spring, pushing the buffer plate, and the sliding frame slides along the base under the deformation of the retraction spring. The sliding frame drives the buffer airbag to move to a position obliquely below the tester through the buffer plate, and the limit plate is released. The positioning spring resets and drives the positioning column to be inserted into the positioning port, and the sliding frame changes from an active state to a fixed state, which can prevent the tester from falling. The tester's back falls to the ground, and the tester stands on the weighing scale. The weighing scale measures the tester's weight. According to the tester's weight, the operator fills the cushion airbag with a specified amount of gas. When the tester weighs more, the cushion airbag is filled with more gas. When the tester weighs less, the cushion airbag is filled with less gas. This can prevent the cushion airbag from rebounding during the cushioning process due to the mismatch between the tester's weight and the amount of gas filled in the airbag, causing harm to the tester. The air pump fills the cushion airbag with gas through the inflation tube. The cushioning gas is filled in the whole part, and the pressure relief threshold of the pressure relief valve is pre-set. When the tester slides down from the outside of the pull-up bar under normal circumstances, the back of the tester fits against the upper wall of the cushioning airbag, and the overall force of the cushioning airbag is relatively uniform, and there will be no large squeezing force in a certain area. When the tester slides down from the outside of the pull-up bar under abnormal circumstances, the shoulders and elbows of the tester will cause a large depression depth in a certain area of ​​the cushioning airbag. The over-stressed cushioning airbag will accelerate wear and damage, shorten its service life, and may lose its cushioning effect due to rupture, thereby losing its To enhance the protection capability for testers, therefore, when the ranging end of the ranging sensor detects that the distance between it and the inner wall of the top of the cushion airbag is small, the air replenishment pump inflates the deeper depressed area of ​​the cushion airbag through the inflation end to maintain the cushioning capacity of the cushion airbag, and the gas in the squeezed part of the cushion airbag flows to other parts, thereby increasing the gas pressure in other parts. When the air pressure in other parts reaches the threshold value preset by the pressure relief valve, the pressure relief valve is turned on to discharge the gas on one or both sides of the depressed part, thereby reducing the probability of the cushion airbag rupture, thereby providing better protection for the testers.

[0011] Specifically, a controller is provided on an upper wall at one end of the base.

[0012] Wherein, the controller is electrically connected to the air pump, the weighing scale, the air supplement pump and the distance measuring sensor respectively.

[0013] Preferably, the model of the distance measuring sensor is C1-JCS1501.

[0014] Furthermore, the model of the controller is HAD-SC200.

[0015] The beneficial effects achieved by adopting the above structure are as follows:

[0016] Compared with the prior art, this solution adopts a combination of weighing and gas filling. Through the adjustable pulling mechanism and anti-fall protection mechanism, the inflation volume of the cushioning airbag can be controlled according to the weight of the tester under the coordinated use of the testing mechanism, the height control mechanism, the buffer mechanism, the positioning mechanism and the anti-cracking mechanism, so as to avoid the rebound of the cushioning airbag during the cushioning operation, and to a certain extent improve the protection ability of the tester who falls. Through the air filling operation of the cushioning airbag depression by the air filling pump, the cushioning capacity of the area with a larger depression depth of the cushioning airbag can be maintained, and under the setting of the pressure relief valve, When the gas pressure on both sides of the depressed part of the buffer airbag is high, the gas that increases the internal pressure of the buffer airbag can be discharged to avoid the rupture of the buffer airbag and ensure the buffering effect of the buffer airbag. The air replenishing pump inflates the deeper depressed area of ​​the buffer airbag through the inflation end to maintain the buffering capacity of the buffer airbag. The gas in the squeezed part of the buffer airbag flows to other parts, increasing the gas pressure in other parts. When the air pressure in other parts reaches the preset threshold of the pressure relief valve, the pressure relief valve is turned on to discharge the gas on one or both sides of the depressed part, reducing the probability of the buffer airbag rupture, thereby providing better protection for the testers.

[0034] A controller 34 is disposed on an upper wall at one end of the base 1 .

[0035] The controller 34 is electrically connected to the air pump 21 , the weighing scale 31 , the air supplement pump 30 and the distance measuring sensor 33 respectively.

[0036] The model of the distance measuring sensor 33 is C1-JCS1501.

[0037] The model of the controller 34 is HAD-SC200.

[0038] When in use, the height of the pull-up bar 8 is adjusted according to the height of the person to be tested, and the locking frame 12 is pulled. The locking frame 12 slides away from the locking wheel 13 along the test plate 5 under the action of the elastic deformation of the height control spring 11, and the locking wheel 13 is rotated. The locking wheel 13 drives the test frame 7 to rotate and lift up through the test shaft 6, and the test frame 7 drives the pull-up bar 8 to rise in height, and then the locking frame 12 is released. The locking frame 12 is inserted into the locking port 14 under the rebound of the height control spring 11, and the locking wheel 13 is fixed. The test shaft 6 and the locking wheel 13 are changed from an active state to a fixed state. The tester stands on the upper wall of the weighing scale 31, and then the tester jumps up and grabs the pull-up bar 8 with his hands to perform pull-up movements;

[0039] Specifically, when the tester performs the pull-up exercise, his feet are off the ground when holding the pull-up bar 8 with both hands. To prevent the tester from slipping and falling during the exercise, the limit plate 27 is pulled. The limit plate 27 drives the positioning column 25 away from the upper wall of the base 1 through the deformation of the positioning spring 26, pushing the buffer plate 18. The sliding frame 17 slides along the base 1 under the deformation of the retraction spring 20. The sliding frame 17 drives the buffer airbag 19 to move to a position obliquely below the tester through the buffer plate 18. The limit plate 27 is released, and the positioning spring 26 is reset to drive the positioning column 25 to be inserted into the positioning port 24. The sliding frame 17 changes from an active state to a fixed state, which can prevent the tester from falling on his back.

[0040] The tester stands on the upper wall of the weighing scale 31, and the controller 34 controls the weighing scale 31 to start. The weighing scale 31 measures the weight of the tester, and according to the weight of the tester, fills the cushioning airbag 19 with the amount of gas that meets the requirements of the operator. When the tester weighs more, the cushioning airbag 19 is filled with more gas, and when the tester weighs less, the cushioning airbag 19 is filled with less gas, so as to prevent the cushioning airbag 19 from rebounding during the cushioning process due to the mismatch between the weight of the tester and the amount of gas filled in the airbag, thereby causing harm to the tester.

[0041] The controller 34 controls the air pump 21 to start, and the air pump 21 fills the buffer gas into the buffer airbag 19 through the air filling pipe 22. The pressure relief threshold of the pressure relief valve 29 is pre-set. When the tester slides down from the outside of the pull-up rod 8 under normal circumstances, the back of the tester fits against the upper wall of the buffer airbag 19, and the overall force of the buffer airbag 19 is relatively uniform, and there will not be a large squeezing force on a certain area. When the tester slides down from the outside of the pull-up rod 8 under abnormal circumstances, the shoulders and elbows of the tester will cause a large depression depth in a certain area of ​​the buffer airbag 19. The over-stressed buffer airbag 19 will accelerate wear and damage, shorten its service life, and may lose its buffering effect due to rupture, thereby losing its ability to protect the tester;

[0042] Therefore, the controller 34 controls the distance measuring sensor 33 to start. When the distance measuring end of the distance measuring sensor 33 detects that the distance between it and the inner wall of the top of the buffer airbag 19 is small, the controller 34 controls the air supply pump 30 to start. The air supply pump 30 inflates the deeper recessed area of ​​the buffer airbag 19 through the inflation end to maintain the buffering capacity of the buffer airbag 19. The gas in the squeezed part of the buffer airbag 19 flows to other parts, thereby increasing the gas pressure in other parts. When the air pressure in other parts reaches the threshold value preset by the pressure relief valve 29, the pressure relief valve 29 is turned on to discharge the gas on one or both sides of the recessed part, thereby reducing the probability of rupture of the buffer airbag 19, thereby better providing protection for the tester. Repeat the above operation the next time you use it.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
