Description

Technical Field

[0001] This invention relates to the field of tire testing technology, specifically to a tire puncture resistance testing device. Background Technology

[0002] A tire is a ring-shaped elastic rubber product fitted onto the rim (commonly known as a "wheel") of various vehicles or machinery (such as bicycles and balance bikes). During tire production, the tire's puncture resistance needs to be tested to ensure tire quality.

[0003] A search revealed a Chinese patent with application number "CN202511299342.2", which specifically describes a tire puncture resistance testing device and its usage method. The device includes a gantry frame, on which a tire mounting mechanism, a puncture mechanism, and a driving mechanism for moving the puncture mechanism up and down are arranged from bottom to top. The puncture mechanism includes a needle and a sealed syringe. The needle has a central air hole axially connected to the syringe. A rotating ring is rotatably provided on the outer wall of the syringe. Several rectangular blades offset from the syringe axis are equidistantly arranged on the outer circumference of the rotating ring. An annular groove is provided on the inner wall of the rotating ring and is sealed and connected to the syringe. An exhaust hole is horizontally provided within the blades and is connected to the annular groove.

[0004] In existing methods of inspecting bicycle and balance bike tires, the puncture needle is controlled to descend and puncture the tire. During the puncture process, the needle may break and shatter when it pierces the steel wires or hard foreign objects inside the tire, causing the needle to fly out. Since no protective parts are installed, the flying needle can easily hit the workers, posing a safety hazard and increasing the risk of accidents.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides the following technical solutions:

[0021] Example 1

[0022] Please see Figure 1 - Figure 4A tire puncture resistance testing device includes a base plate 1, a fixing frame 2 fixedly connected to the upper side of the base plate 1, a connecting plate 7 fixedly connected to the outer side of the fixing frame 2, a connecting rod 8 fixedly connected to the left side of the connecting plate 7, a positioning plate 6 fixedly connected to the left end of the connecting rod 8, a puncture unit 9 disposed on the left side of the fixing frame 2, two fixing blocks 3 fixedly connected to the upper side of the base plate 1, an electric push rod 4 fixedly connected to the outer side of each of the two fixing blocks 3, a clamping block 5 fixedly connected to the outer end of the electric push rod 4, and a side plate 91 fixedly connected to the left side of the fixing frame 2, with a clamping block 5 fixedly connected to the upper side of the side plate 91. A hydraulic cylinder 92 has a lifting block 93 fixedly connected to its lower output end. A puncture needle 94 is provided on the lower side of the lifting block 93, and a protective component 95 is provided on the outer side of the lifting block 93. The protective component 95 is used to block the splashing puncture needle 94. When puncturing a tire, the tire is first placed between two clamping blocks 5. Then, the electric push rod 4 is controlled to move the clamping blocks 5, so that the clamping blocks 5 limit the tire and the positioning plate 6 positions the tire. Then, the hydraulic cylinder 92 is controlled to lower the lifting block 93, and the lifting block 93 lowers the puncture needle 94 to puncture the tire, which facilitates puncture testing.

[0023] The protective assembly 95 includes a lifting plate 951, which is fixedly connected to the outside of the lifting block 93. Two sliding grooves 952 are formed on the outside of the lifting plate 951. A slider 953 is slidably connected to the inner side of each of the two sliding grooves 952. A base block 954 is fixedly connected to the lower side of each slider 953. Protective covers 955 are fixedly connected to the lower sides of both base blocks 954. A cover plate 956 is provided on the outside of the puncture needle 94. A contact cover 957 is fixedly connected to the lower side of the cover plate 956. An installation device is fixedly connected to the outside of the cover plate 956. Block 958 is mounted on a sliding rod 959, the upper end of which passes through the upper side of the lifting plate 951 and is fixedly connected to a top block 9510. A lifting ring 9512 is fixedly connected to the outer side of the top block 9510. Rotating blocks 9513 are fixedly connected to both sides of the lifting ring 9512. An inclined plate 9514 is rotatably connected to the outer side of the rotating blocks 9513. Rotating blocks 9515 are fixedly connected to the upper side of both sliding blocks 953. Rotating blocks 9515 are rotatably connected to the inclined plate 9514. The slide bar 959 is slidably connected to the lifting plate 951. A spring 9511 is fixedly connected between the top block 9510 and the lifting plate 951. The left and right inclined plates 9514 are symmetrically distributed. The protective cover 955 is made of rubber. When puncturing the tire, the hydraulic cylinder 92 drives the lifting block 93 to descend, and the lifting block 93 drives the contact cover 957 to descend, so that the contact cover 957 contacts the tire. At this time, the puncture needle 94 continues to descend, so that the lifting ring 9512 rises relative to the lifting block 93. The lifting ring 9512 drives... The inclined plate 9514 rotates, which drives the slider 953 to move. Since the two inclined plates 9514 are symmetrically distributed, the sliders 953 on both sides move closer to each other. The sliders 953 drive the base block 954 to move, and the base block 954 drives the protective cover 955 to move, so that the protective covers 955 on both sides move closer to each other. This makes it easier for the protective covers 955 on both sides to block the splashing puncture needle 94 when puncturing the tire, and to block the splashing puncture needle 94 again through the contact cover 957, thereby increasing the safety of the device during use.

The puncture unit 9 includes a side plate 91, which is fixedly connected to the left side of the fixing frame 2. A connecting plate 7 is fixedly connected to the upper side of the side plate 91. A hydraulic cylinder 92 is provided, and a lifting block 93 is fixedly connected to the output end of the lower side of the hydraulic cylinder 92. A puncture needle 94 is provided on the lower side of the lifting block 93, and a protective component 95 is provided on the outer side of the lifting block 93. The protective component 95 is used to block the splashing puncture needle 94. When puncturing the tire, the tire is first placed between two clamping blocks 5. Then, the electric push rod 4 is controlled to drive the clamping blocks 5 to move, so that the clamping blocks 5 limit the tire and the positioning plate 6 positions the tire. Then, the hydraulic cylinder 92 is controlled to drive the lifting block 93 to descend. The lifting block 93 drives the puncture needle 94 to descend and puncture the tire, which facilitates puncture testing.

[0026] A fixing ring 9516 is fixedly connected to the inner side of the contact cover 957. Multiple moving grooves 9517 are provided on the outer side of the fixing ring 9516. Moving blocks 9518 are slidably connected to the inner side of the moving grooves 9517. Branch plates 9532 are fixedly connected to the lower side of each moving block 9518. Branch blocks 9533 are fixedly connected to the lower side of each branch plate 9532. A control rod 9538 is provided on the outer side of each branch block 9533. A limit roller 9534 is provided at the outer end of the control rod 9538. Rotary blocks 9519 are fixedly connected to the upper side of each moving block 9518. A linkage plate 9520 is rotatably connected to the outer side of each rotating block 9519. A rotating... Block 4 9521, a control ring 9522 is fixedly connected to the upper side of the rotating block 4 9521, a moving rod 9523 is fixedly connected to the upper side of the control ring 9522, a top ring 9525 is fixedly connected to the upper end of the moving rod 9523, a spring 9524 is fixedly connected between the top ring 9525 and the contact cover 957, two stabilizing blocks 9526 are fixedly connected to the upper side of the cover plate 956, a rocker 9527 is rotatably connected between the two stabilizing blocks 9526, an inclined plate 9528 is rotatably connected to the outer side of the rocker 9527, a connecting block 9529 is fixedly connected to the upper side of the top ring 9525, the inclined plate 9528 is rotatably connected to the connecting block 9529, and the lower side of the lifting plate 951 is fixed. A base rod 9530 is connected, and a contact roller 9531 is fixedly connected to the lower end of the base rod 9530. A spring 9535 is fixedly connected between the limit roller 9534 and the branch block 9533. A control rod 9538 is slidably connected to the branch block 9533. During piercing, the lifting plate 951 descends, which in turn causes the base rod 9530 to descend. The base rod 9531 then causes the contact roller 9531 to descend, bringing it into contact with the rocker plate 9527. This causes the contact roller 9531 to press down on the rocker plate 9527, which rotates. The rocker plate 9527 then rotates the inclined plate 9528, which in turn rotates the top ring 9525, causing it to rise. The top ring 9525 drives the moving rod 9523 to rise, the moving rod 9523 drives the control ring 9522 to rise, the control ring 9522 drives the linkage plate 9520 to rotate, and the linkage plate 9520 drives the moving block 9518 to move. Since the multiple linkage plates 9520 are arranged in a circular array, the multiple moving blocks 9518 move closer to each other. The moving block 9518 drives the branch plate 9532 to move, the branch plate 9532 drives the branch block 9533 to move, and the branch block 9533 drives the limiting roller 9534 to move, so that the multiple limiting rollers 9534 move closer to the puncture needle 94, which facilitates the multiple limiting rollers 9534 to limit the puncture needle 94 and increases the stability of the puncture needle 94 during puncture.

[0027] An electromagnet 9536 is fixedly connected to the outside of the control rod 9538, and two metal plates 9537 are fixedly connected to the lower side of the branch plate 9532. Through the control rod 9538 and the spring 9535, the limiting roller 9534 can conveniently limit the puncture needles 94 of various sizes. When limiting, the electromagnet 9536 is activated, so that the electromagnet 9536 and the metal plates 9537 are attracted to each other, which facilitates the limiting roller 9534 to be limited.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the tire is first placed on the outside of the positioning plate 6. Then, the electric push rod 4 is controlled to move the clamping block 5, so that the clamping blocks 5 on both sides limit the tire. Then, the hydraulic cylinder 92 is controlled to drive the puncture needle 94 to descend and puncture the tire. At the same time, the lifting plate 951 drives the contact cover 957 to contact the tire. The puncture needle 94 is continued to descend, causing the lifting ring 9512 to rise. Under the action of the inclined plate 9514, the slider 953, and the bottom block 954, the protective covers 955 on both sides are brought closer to each other. The contact cover 957 blocks the splashing puncture needle 94, increasing the safety of the device. At the same time, the lifting plate 951 drives the bottom rod 9530 and the contact roller 9531 to descend, pressing down the rocker plate 9527. Under the action of the inclined plate 9528, the top ring 9525 rises. Under the action of the moving rod 9523, the control ring 9522, and the linkage plate 9520, the multiple limiting rollers 9534 at the bottom move, limiting the puncture needle 94 and increasing the stability of the puncture needle 94 during puncture.
