Description

Technical Field

[0001] The invention relates to the technical field of elasticity detection of plastic runways, in particular to an elasticity detection device for plastic runways. Background Art

[0002] The plastic track is also called the all-weather track for athletics. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. The plastic track is composed of materials such as polyurethane rubber, has certain elasticity and color, and has certain UV resistance and aging resistance. When performing elasticity testing on plastic track samples, a tensile tester is required.

[0003] However, in the use of existing tensile testers, operators need to manually rotate the fixing components to fix the two ends of the plastic track sample. Manual adjustment of the position of the fixing components cannot ensure the same position, which makes the clamping force on the two ends of the sample different, which can easily affect the test results of the sample and is not convenient for operators to quickly disassemble and assemble the sample. In addition, when the fixed sample is not in a vertical state with the fixing component, it may not be possible to ensure that the sample is subjected to axial stretching, which can easily affect the accuracy of the sample test data. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides an elasticity detection device for a plastic track.

[0005] The technical solution adopted by the present invention to solve the technical problem is: the elasticity detection device of the plastic track comprises a base, on which a detector body is fixedly installed; a sliding mechanism is slidably installed on the detector body; a fixing mechanism is fixedly installed on the base; a connecting block is fixed on the sliding mechanism and the fixing mechanism; a clamping mechanism is installed on the connecting block; a guiding mechanism is fixed on the clamping mechanism;

[0006] The cam is provided with a plurality of sliding rods, and the plurality of sliding rods are connected to the plurality of clamping blocks, the plurality of clamping blocks are connected to the plurality of clamping blocks by a plurality of sliding rods.

[0007] Specifically, the guide mechanism includes a support frame and a slide plate, two support frames are fixedly installed on the top of the slide rod, the support frame is slidably connected with a slide plate, a telescopic spring is fixedly installed on the slide plate, the telescopic spring is fixedly connected to the support frame, a connecting shaft is fixedly installed between the two slide plates, a guide wheel is rotatably connected to the connecting shaft, a washer is sleeved on the guide wheel, a slide groove is provided on the support frame, the two slide plates and the slide groove are symmetrically arranged, a slide plate is slidably arranged on the slide groove, the guide wheel and the slide plate are rotatably connected, and the cross-sectional diameter of the washer is larger than the cross-sectional diameter of the guide wheel.

[0008] Specifically, the fixing mechanism includes a base plate and a positioning block, the base is fixedly installed with the base, the top of the base plate is fixedly connected with the positioning block, the positioning block is snap-connected with a limit block, the positioning block is rotatably connected with a screw rod, the screw rod is threadedly connected with two fixing rods, the fixing rod is fixedly installed with a clamping block, the clamping block is snap-connected with the limit block, the threads at both ends of the screw rod are in opposite directions, and the fixing rod is slidably connected with the positioning block.

[0009] Specifically, the sliding mechanism includes a finger rod and a slider. The slider is slidably installed on the detector body. Two finger rods are symmetrically fixedly connected to the slider. A sensor is fixedly installed at the bottom end of the slider. A connecting block is fixedly installed on the sensor and the limit block.

[0010] The beneficial effects of the present invention are:

[0011] (1) The elasticity detection device for the plastic track described in the present invention uses a tool to rotate the fixing mechanism, which can facilitate the operator to disassemble and assemble the clamping mechanism on the connecting block, thereby facilitating the improvement of the use effect of the detection device, that is, when the operator installs a connecting block, the operator can first put the limit block fixed at the bottom end of the connecting block into the positioning block, and the positioning block is fixed at the top of the bottom plate. When the limit block is engaged with the inside of the positioning block, the operator can use a tool to rotate the screw installed on the positioning block. Since the end of the screw is provided with a mounting hole with a hexagonal structure, when the screw is turned, the screw can be rotated inside the positioning block. The threads at both ends of the screw are in opposite directions. When it rotates inside the positioning block, the fixing rod threaded on the screw can slide along the side wall of the screw in the positioning block. When the two fixing rods slide toward each other, the clamping block fixed at the end can be driven to engage with the inside of the limit block, so that the clamping block limits the limit block, thereby facilitating the fixing of the limit block in the positioning block, and also facilitating the operator to disassemble and assemble the limit block during use.

[0012] (2) The elasticity detection device for the plastic track described in the present invention can start the clamping mechanism to drive the guide mechanism to slide, thereby facilitating the operator to place one end of the plastic track sample block into the clamping mechanism and the guide mechanism, thereby facilitating the fixing of the sample block, that is, when fixing the plastic track sample block, the control switch of the hydraulic rod can be started first, and the hydraulic rod drives the card plate fixed at the telescopic end to slide toward the bottom end of the fixed block. The two groups of card slots provided on the card plate are equipped with card rods. When the card plate slides along the inner wall of the fixed block, the card rod can drive the connecting rod fixed to the side wall to move under the limiting action of the card slot. Since the connecting rod is limited by the limiting groove provided in the fixed block, when the card plate moves downward, the inner wall exerts a force on the card rod, thereby causing the card rod to drive the connecting rod to slide in the direction close to the side wall of the fixed block, and the connecting rod moves along the fixed block. When the inner wall slides, it can drive the sliding rod fixed on the top to slide in the through groove provided in the fixed block, and a clamping block is fixed at the end of the sliding rod. The two clamping blocks are in a state of mutual engagement before. When the sliding rod slides, a gap can be generated between the two clamping blocks, and one end of the plastic runway sample block is placed in the gap. Restarting the hydraulic rod can make the clamping plate move up, and then the connecting rod drives the sliding rod to move toward the center of the fixed block. The two clamping blocks can be re-engaged when they contact one end of the sample block, and the corresponding side walls of the clamping blocks are arranged in a serrated structure. When the sample block is clamped, the contact area between the sample block and the clamping block can be increased, thereby facilitating the improvement of the fixing effect of the sample block; using the same method, the other end of the sample block can be fixed between a group of clamping blocks close to the sensor, thereby facilitating the rapid clamping and fixing of both ends of the sample block.

[0013] (3) The elasticity detection device for the plastic track described in the present invention fixes the other end of the sample block in a clamping mechanism close to the sliding mechanism. When the sliding mechanism is started, it can drive the sample block on the clamping mechanism to slide in the direction close to the top of the detector body, thereby facilitating the detection of the elasticity of the sample block, that is, when the two ends of the sample block are fixed, the sliding rod will drive the support frame fixed at the top to slide, and a slide plate is slidably installed on the support frame, and a connecting shaft is fixed between the two slide plates. When the sliding rod is reset, the clamping block clamps the end of the sample block, thereby making the gasket sleeved on the guide wheel contact the side wall of the sample block. When the thickness of the test sample block is inconsistent, the guide wheel is driven by the contact force to move the connecting shaft, thereby making the end of the slide plate slide in the support frame. When the detector moves, the telescopic spring can be squeezed. The telescopic spring is installed in the support frame. When the telescopic spring is in a compressed state, the position of the guide wheel can be displaced as the thickness of the sample block changes. During testing, the control switch of the detector body is started, so that the finger rod fixed on the slider is driven to slide along the side wall of the detector body. The sample block slides toward the top of the detector body under the action of the tensile force, and when the sample block contacts the gasket, the guide wheel can be driven to rotate along the connecting shaft, so that it is convenient to guide the sample block while making it perpendicular to the two fixed blocks during the stretching process. The test data can be transmitted to the control console through the sensor installed on the slider, so as to facilitate the test of the elasticity of the plastic track sample block.

[0028] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the clamping mechanism 5 includes a fixed block 501 and a slide bar 502. The connecting block 4 is fixedly mounted with the fixed block 501. Two slide bars 502 are slidably connected to the fixed block 501. The slide bars 502 are fixedly mounted with a clamping block 503. A hydraulic rod 505 is fixedly mounted on the fixed block 501. The telescopic end of the hydraulic rod 505 is fixedly connected with a clamping plate 506. The clamping plate 506 is provided with a clamping groove 507. The clamping plate 506 is slidably connected with a clamping rod 508. The clamping rod 508 is fixedly mounted with a connecting rod 50 9. The two groups of connecting rods 509 are fixedly connected to the two sliding rods 502 respectively. The fixed block 501 is symmetrically provided with two through grooves 504. The two clamping blocks 503 are snap-fitted and connected, and the contacting parts of the two clamping blocks 503 are arranged in a serrated structure. The slot 507 is arranged in a V-shaped structure. The slot 507 is slidably connected with a clamping rod 508. The connecting rod 509 is slidably connected with the clamping plate 506. The through groove 504 is slidably provided with a sliding rod 502. The clamping plate 506 is slidably connected with the fixed block 501.

[0029] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig. 9As shown, the guide mechanism 6 includes a support frame 601 and a slide plate 604, two support frames 601 are fixedly installed on the top of the slide bar 502, the support frame 601 is slidably connected with a slide plate 604, a telescopic spring 605 is fixedly installed on the slide plate 604, the telescopic spring 605 is fixedly connected to the support frame 601, a connecting shaft 606 is fixedly installed between the two slide plates 604, a guide wheel 602 is rotatably connected to the connecting shaft 606, a washer 603 is sleeved on the guide wheel 602, a slide groove 607 is provided on the support frame 601, the two slide plates 604 and the slide groove 607 are symmetrically arranged, and a sliding groove 607 is slidably provided at the slide groove 607. The guide wheel 602 is rotatably connected to the slide plate 604, and the cross-sectional diameter of the washer 603 is larger than the cross-sectional diameter of the guide wheel 602. The clamping mechanism 5 is started to drive the guide mechanism 6 to slide, so that it is convenient for the operator to place one end of the plastic runway sample block into the clamping mechanism 5 and the guide mechanism 6, so as to facilitate the fixation of the sample block. That is, when fixing the plastic runway sample block, the control switch of the hydraulic rod 505 can be started first, and the hydraulic rod 505 drives the card plate 506 fixed at the telescopic end to slide toward the bottom end of the fixed block 501. The two groups of card slots 507 on the card plate 506 are equipped with card rods 508. When the card plate 506 moves along the fixed block 50 When the inner wall of the fixing block 501 slides, the clamping rod 508 can drive the connecting rod 509 fixed on the side wall to move under the limiting effect of the clamping groove 507. Since the connecting rod 509 is limited by the limiting groove provided in the fixing block 501, when the clamping plate 506 moves downward, the inner wall exerts a force on the clamping rod 508, thereby causing the clamping rod 508 to drive the connecting rod 509 to slide in the direction close to the side wall of the fixing block 501. When the connecting rod 509 slides along the inner wall of the fixing block 501, it can drive the sliding rod 502 fixed on the top to slide in the through groove 504 provided in the fixing block 501. A clamping block 503 is fixed at the end of the sliding rod 502. The two clamping blocks 503 are in a mutually engaged state. When the sliding rod 502 slides, A gap is created between the two clamping blocks 503, one end of the plastic track sample block is placed in the gap, and the hydraulic rod 505 is restarted to move the clamping plate 506 upward, thereby causing the connecting rod 509 to drive the sliding rod 502 to move toward the center of the fixed block 501. The two clamping blocks 503 can be re-engaged when they contact one end of the sample block, and the corresponding side walls of the clamping blocks 503 are arranged in a serrated structure. When clamping the sample block, the contact area between the sample block and the clamping blocks 503 can be increased, thereby facilitating the improvement of the fixing effect of the sample block; using the same method, the other end of the sample block can be fixed between a group of clamping blocks 503 close to the sensor 303, thereby facilitating the rapid clamping and fixing of both ends of the sample block.

[0030] Specifically, Figure 1 , Figure 3 , Figure 5 and Fig.10As shown, the fixing mechanism 7 includes a base plate 701 and a positioning block 702, the base 1 is fixedly installed with the base plate 701, the top of the base plate 701 is fixedly connected with the positioning block 702, the positioning block 702 is engaged with a limiting block 704, the positioning block 702 is rotatably connected with a screw rod 703, the screw rod 703 is threadedly connected with two fixing rods 706, a clamping block 705 is fixedly installed on the fixing rod 706, the clamping block 705 is engaged with the limiting block 704, the threads at both ends of the screw rod 703 are in opposite directions, the fixing rod 706 is slidably connected with the positioning block 702, and the fixing mechanism 7 is rotated by a tool, so that the operator can disassemble and assemble the clamping mechanism 5 on the connecting block 4, thereby improving the use effect of the detection device, that is, when the operator installs a connecting block 4, the limiting block 704 fixed at the bottom end of the connecting block 4 can be first clamped into the positioning block When the screw rod 703 is rotated, the fixing rod 706 threadedly connected to the screw rod 703 can slide in the positioning block 702 along the side wall of the screw rod 703. When the two fixing rods 706 slide toward each other, the clamping block 705 fixed at the end can be driven to be clamped in the limiting block 704, so that the clamping block 705 limits the limiting block 704, thereby facilitating the fixing of the limiting block 704 in the positioning block 702 and facilitating the disassembly and assembly of the limiting block 704 during use.

[0031] Specifically, Figure 1 , Figure 2 and Figure 4As shown, the sliding mechanism 3 includes a finger rod 301 and a slider 302. The slider 302 is slidably mounted on the detector body 2. Two finger rods 301 are symmetrically fixedly connected to the slider 302. A sensor 303 is fixedly mounted on the bottom end of the slider 302. A connecting block 4 is fixedly mounted on the sensor 303 and the limit block 704. The other end of the sample block is fixed in a clamping mechanism 5 close to the sliding mechanism 3. When the sliding mechanism 3 is started, it can drive the clamping mechanism 5 to load the sample block. Slide toward the direction close to the top of the detector body 2, so as to facilitate the detection of the elasticity of the sample block, that is: when the two ends of the sample block are fixed, the sliding of the slide bar 502 will drive the support frame 601 fixed at the top to slide, and a slide plate 604 is slidably installed on the support frame 601, and a connecting shaft 606 is fixed between the two slide plates 604. When the slide bar 502 is reset, the clamping block 503 clamps the end of the sample block, so that the gasket 603 sleeved on the guide wheel 602 can be made to contact with the side wall of the sample block. When the sample block is detected When the thickness is inconsistent, the guide wheel 602 is driven by the resistance force to move the connecting shaft 606, so that the end of the slide plate 604 can squeeze the telescopic spring 605 when sliding in the support frame 601. The telescopic spring 605 is installed in the support frame 601. When the telescopic spring 605 is in a compressed state, the position of the guide wheel 602 can be displaced as the thickness of the sample block changes; during detection, the control switch of the detector body 2 is started, so that it drives the finger rod 301 fixed on the slider 302 to slide along the side wall of the detector body 2. The sample block slides toward the top direction of the detector body 2 under the action of the tensile force, and when the sample block contacts the gasket 603, the guide wheel 602 can be driven to rotate along the connecting shaft 606, so that it is convenient to guide the sample block while making it perpendicular to the two fixed blocks 501 during the stretching process. The detected data can be transmitted to the control console through the sensor 303 installed on the slider 302, so as to facilitate the detection of the elasticity of the plastic track sample block.

[0032] When the present invention is used, first, when installing a connection block 4, the operator can first insert the limit block 704 fixed at the bottom end of the connection block 4 into the positioning block 702, and the positioning block 702 is fixed to the top of the bottom plate 701. When the limit block 704 is engaged with the inside of the positioning block 702, the operator can use a tool to rotate the screw rod 703 installed on the positioning block 702. Since the end of the screw rod 703 is provided with a mounting hole with a hexagonal structure, when the screw rod 703 is turned, the screw rod 703 can be rotated inside the positioning block 702. The threads at both ends of the screw rod 703 are in opposite directions. When the screw rod 703 rotates inside the positioning block 702, the fixing rod 706 threadedly connected to the screw rod 703 can slide along the side wall of the screw rod 703 inside the positioning block 702. When the two fixing rods 706 slide toward each other, the clamping block 705 fixed at the end can be driven to engage inside the limit block 704, so that the clamping block 705 limits the limit block 704, thereby facilitating the fixation of the limit block 704 in the positioning block 702, and also facilitating the operator to disassemble and assemble the limit block 704 during use.

[0033] When fixing the plastic track sample block, the control switch of the hydraulic rod 505 can be started first. The hydraulic rod 505 drives the card plate 506 fixed at the telescopic end to slide toward the bottom end of the fixed block 501. The card plate 506 is provided with two groups of card slots 507 with card rods 508 installed. When the card plate 506 slides along the inner wall of the fixed block 501, the card rod 508 can drive the connecting rod 509 fixed on the side wall to move under the limiting action of the card slot 507. Since the connecting rod 509 is limited by the limiting groove provided in the fixed block 501, when the card plate 506 moves downward, the inner wall exerts a force on the card rod 508, thereby causing the card rod 508 to drive the connecting rod 509 to slide in the direction close to the side wall of the fixed block 501. When the connecting rod 509 slides along the inner wall of the fixed block 501, it can drive the sliding rod 502 fixed on the top to move in the through groove 504 provided in the fixed block 501. When the slider 502 is in a state of being engaged with each other, a gap is generated between the two clamping blocks 503, and one end of the plastic runway sample block is placed in the gap. The hydraulic rod 505 is restarted to move the clamping plate 506 upward, and the connecting rod 509 drives the slider 502 to move toward the center of the fixed block 501. When the two clamping blocks 503 contact one end of the sample block, they can be re-engaged, and the corresponding side walls of the clamping blocks 503 are arranged in a serrated structure. When the sample block is clamped, the contact area between the sample block and the clamping blocks 503 can be increased, thereby facilitating the improvement of the fixing effect of the sample block. In the same way, the other end of the sample block can be fixed between a group of clamping blocks 503 close to the sensor 303, thereby facilitating the rapid clamping and fixing of the two ends of the sample block.

[0034] When the two ends of the sample block are fixed, the sliding rod 502 will drive the support frame 601 fixed at the top to slide when it slides. A slide plate 604 is slidably installed on the support frame 601, and a connecting shaft 606 is fixed between the two slide plates 604. When the sliding rod 502 is reset, the clamping block 503 clamps the end of the sample block, so that the washer 603 sleeved on the guide wheel 602 can contact the side wall of the sample block. When the thickness of the test sample block is inconsistent, the guide wheel 602 is driven by the contact force to move the connecting shaft 606, so that the end of the slide plate 604 can slide in the support frame 601 to squeeze the telescopic spring 605. The telescopic spring 605 is installed in the support frame 601. When the telescopic spring 605 is in a compressed state, The position of the guide wheel 602 can be displaced as the thickness of the sample block changes; during testing, the control switch of the detector body 2 is started, so that it drives the finger rod 301 fixed on the slider 302 to slide along the side wall of the detector body 2. The sample block slides toward the top of the detector body 2 under the action of the tensile force, and when the sample block contacts the gasket 603, the guide wheel 602 can be driven to rotate along the connecting shaft 606, so that it is convenient to guide the sample block and it can also be in a vertical state with the two fixed blocks 501 during the stretching process. The test data can be transmitted to the control console through the sensor 303 installed on the slider 302, so as to facilitate the detection of the elasticity of the plastic track sample block.
