Description

Technical Field

[0001] This utility model relates to the field of spring testing technology, and more specifically, to a mobile spring force measuring tension and compression testing machine. Background Technology

[0002] A spring force testing machine is a specialized piece of equipment used to test the mechanical properties of springs. It can accurately apply tensile and compressive forces to simulate the actual stress state of a spring during operation. Through high-precision sensors, it can accurately measure the force changes of the spring at different stress stages in real time, and simultaneously display and record the data. This equipment can efficiently complete tests such as spring tensile and compressive strength and fatigue life, providing crucial information for spring quality control and optimized design. It is widely used in many industries, including machinery, automotive, and electronics.

[0003] Publication No. (CN212844676U) discloses a tensile testing machine for spring testing with a safety protection structure, including a base, an oil tank, and a pressure relief switch. A support is mounted on the upper surface of the base, and a groove is formed on the upper surface of the support. The inner surface of the groove connects to the outer surface of a pulley. The upper end of the pulley is connected to the lower end of a protective plate. A support column is provided in the middle of the protective plate, and the lower end of the support column is mounted on the upper end of the base. An upper baffle is mounted on the upper end of the support column, and a hook is mounted on the lower surface of the upper baffle. A movable frame is mounted on one side of the hook. This tensile testing machine for spring testing with a safety protection structure has a protective plate outside the support column. The protective plate, made of tempered glass, isolates the device while allowing direct observation of the device during spring measurement, preventing the tensile testing machine from breaking the spring during measurement and causing fragments to fly and injure the operator.

[0004] However, this type of tensile testing machine for spring testing with a safety protection structure has the following drawbacks: it can only pull the protective plate for protection, but cannot effectively store the spring or observe its state while protecting it. Furthermore, the upper and lower pull-type protective plates cannot be fixed when fully pulled up, and the internal spring state is completely invisible. Continuous increase in testing may cause the spring to collapse and attack, which cannot be detected in advance and cannot be stopped in advance, resulting in a great waste of resources. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a mobile spring force measuring tension and compression testing machine to solve the problem that it is impossible to effectively store and observe the spring state while protecting it in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mobile spring force measuring tension and compression testing machine, comprising...

[0007] The frame has a protective plate slidably connected to its inner wall, a fixed frame fixedly connected to the outer side of the protective plate, two locking pins fixedly connected to the inner wall of the fixed frame, a rotating plate rotatably connected to the outer side of each locking pin, a locking post fixedly connected to the inner wall of the rotating plate, a support rod rotatably connected to the outer side of the locking post, a connecting block fixedly connected to the outer side of the support rod, a spring fixedly connected to the outer side of the connecting block, a slider fixedly connected to the end of the spring away from the connecting block, a limit post movably connected to the inner wall of the rotating plate, multiple stabilizing grooves opened on the outer side of the fixed frame, and a protective component for protecting subsequent parts slidably connected to the inner wall of the protective plate.

[0008] The protective assembly includes two limiting plates, both of which are slidably connected to the inner wall of the protective plate. An extension plate is fixedly connected to the outside of each limiting plate, and a spring is fixedly connected to the end of each limiting plate away from the extension plate.

[0009] The limiting post is externally movably connected to the inner wall of the protective plate, and the rotating plate is externally movably connected to the inner wall of the fixed frame.

[0010] The outer side of the support rod is in contact with the inner wall of the rotating plate, and the end of the support rod away from the locking pin is movably connected to the inner wall of the fixed frame.

[0011] The slider is externally slidably connected to the inner wall of the rotating plate, and the outer side of the rotating plate is in contact with the inner wall of the stabilizing groove.

[0012] The extension plate is slidably connected to the inner wall of the protective plate, and the outer side of the second spring is in contact with the inner wall of the protective plate.

[0013] The outer surface of the first spring is in contact with the outer surface of the rotating plate, and the outer surface of the first spring is in contact with the outer surface of the fixed frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, lifting the two limiting posts disengages them from the extension plates. At this point, the spring inside the slider releases its potential energy, driving the rotating plate to rotate around the locking pin on the fixed frame and return to its original position, sliding into the stabilizing groove for storage. Simultaneously, the support rod rotates around the locking post. During storage, the two extension plates move, expanding the protective area and effectively ensuring the safety of workers.

[0016] In the above solution, by setting up protective components, the extension plate slides out from inside the protective plate when it moves due to the action of the spring connected to the limiting plate, thus expanding the protective area. After the work is completed, the extension plate is fixed by the linkage engagement between the limiting post and the extension plate. Then, the position of the protective plate on the frame is moved to reduce the space occupied, facilitate storage, and improve space utilization. Attached Figure Description

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a mobile spring force measuring tension and compression testing machine, including...

[0024] The frame 1 has a protective plate 2 slidably connected to its inner wall. Frame 1 serves as the basic support structure for the entire testing machine, providing a location for installation and fixation. The protective plate 2 can slide on the inner wall of frame 1, allowing for easy adjustment of its position to suit different work requirements or for storage, thus improving space utilization. A fixing frame 3 is fixedly connected to the outside of the protective plate 2. The protective plate 2 provides protection, while the fixing frame 3 provides stable support. Two locking pins 4 are fixedly connected to the inner wall of the fixing frame 3. These pins 4 serve as the connection points for the rotation of the rotating plate 5, providing a rotatable axis for the plate 5 to rotate around. Rotating plates 5 are rotatably connected to the outside of both locking pins 4. Through this rotatable connection, the rotating plates 5 can rotate as needed, changing their position to achieve storage or unfolding functions. A locking post 6 is fixedly connected to the inner wall of the rotating plate 5. The locking post 6 is fixed to the inner wall of the rotating plate 5 and is used to connect the support rod 7, so that the support rod 7 can rotate around the locking post 6, thereby realizing the supporting or auxiliary storage function of the rotating plate 5 in different positions.

[0025] A support rod 7 is rotatably connected to the external of the locking post 6. The support rod 7 is rotatably connected to the locking post 6. During the rotation of the rotating plate 5, the support rod 7 rotates accordingly to adjust its position. When stored, it rotates and folds together with the rotating plate 5, and when unfolded, it provides some support. A connecting block 8 is fixedly connected to the external of the support rod 7. The connecting block 8 is mainly used to connect to spring 9, which transmits force, transferring the force of spring 9 to the support rod 7 or vice versa. Spring 9 is also fixedly connected to the external of the connecting block 8. When the rotating plate 5 is not in the stored state, spring 9 stores a certain amount of potential energy. When the rotating plate 5 needs to be stored, spring 9 releases this potential energy, pushing the rotating plate 5 back into the stabilizing groove 12, thus achieving automatic storage of the rotating plate 5. A slider 10 is fixedly connected to one end of spring 9 away from connecting block 8. The slider 10 is connected to one end of spring 9 and can slide on the inner wall of rotating plate 5. During the process of spring 9 releasing potential energy to push rotating plate 5 to reset, slider 10 slides on the inner wall of rotating plate 5 to assist the rotation and reset of rotating plate 5, while limiting the movement direction of spring 9 to a certain extent.

[0026] A limiting post 11 is movably connected to the inner wall of the rotating plate 5. The limiting post 11 primarily restricts the position of the rotating plate 5. When the rotating plate 5 is unfolded for operation, the limiting post 11 fixes its position, preventing it from rotating arbitrarily. When it needs to be stored, the limiting post 11 is lifted to release the restriction on the rotating plate 5. Multiple stabilizing slots 12 are provided on the outside of the fixing frame 3. When the rotating plate 5 is stored, it rotates to the position corresponding to the stabilizing slot 12 and embeds itself in the slot, ensuring the rotating plate 5 remains stably stored without wobbling. The protective component is slidably connected to the inner wall of the protective plate 2. It unfolds during operation to increase the protective area, providing better protection for personnel and internal components. When stored, it slides into the protective plate 2, reducing the overall volume and facilitating storage.

[0027] The protective assembly includes two limiting plates 13, both of which are slidably connected to the inner wall of the protective plate 2. The limiting plates 13, being part of the protective assembly, primarily limit and support the extension plate 14. During the movement of the extension plate 14, the limiting plates 13 move together with it, simultaneously connecting to a second spring 15 and transmitting its force. The extension plate 14 is fixedly connected to the outside of the limiting plates 13. When the protective assembly is deployed, the extension plate 14 extends from inside the protective plate 2, extending the protective area of ​​the protective plate 2 and better preventing injury to workers in the event of spring collapse, thus greatly protecting worker safety. The end of the limiting plate 13 furthest from the extension plate 14 is fixedly connected to the second spring 15. Spring 2 15 is connected to the end of the limiting plate 13 away from the extension plate 14. When the protective assembly needs to be unfolded, spring 2 15 releases potential energy, pushing the limiting plate 13 and the extension plate 14 to move outward from the inside of the protective plate 2, increasing the protective area. When it needs to be retracted, spring 2 15 stores potential energy, allowing the extension plate 14 and the limiting plate 13 to smoothly return to the inside of the protective plate 2.

[0028] The limiting post 11 is externally and movably connected to the inner wall of the protective plate 2, and the rotating plate 5 is externally and movably connected to the inner wall of the fixing frame 3. The limiting post 11 is movably connected to the inner wall of the protective plate 2, which facilitates the lifting operation when needed to release the restriction on the rotating plate 5; the rotating plate 5 is movably connected to the inner wall of the fixing frame 3, which ensures that the rotating plate 5 can rotate around the locking pin 4, realizing the functions of unfolding and storing.

[0029] The outer side of the support rod 7 contacts the inner wall of the rotating plate 5, and the end of the support rod 7 away from the locking post 6 is movably connected to the inner wall of the fixed frame 3. The support rod 7 contacts the inner wall of the rotating plate 5, and during the rotation of the rotating plate 5, the support rod 7 rotates together with the rotating plate 5. Its end away from the locking post 6 is movably connected to the inner wall of the fixed frame 3, ensuring stability during rotation. Simultaneously, when the rotating plate 5 is unfolded, the support rod 7 provides a certain supporting force.

[0030] The slider 10 is externally slidably connected to the inner wall of the rotating plate 5, and the outer side of the rotating plate 5 is in contact with the inner wall of the stabilizing groove 12. The slider 10 is slidably connected to the inner wall of the rotating plate 5. During the process of the spring 9 pushing the rotating plate 5 to reset, the slider 10 slides on the inner wall of the rotating plate 5 to assist the rotation and reset of the rotating plate 5. The rotating plate 5 is in contact with the inner wall of the stabilizing groove 12. When the rotating plate 5 is retracted, the rotating plate 5 is embedded in the stabilizing groove 12 to achieve a stable retracted state.

[0031] The extension plate 14 is slidably connected to the inner wall of the protective plate 2, and the outer side of the second spring 15 is in contact with the inner wall of the protective plate 2. The extension plate 14 is slidably connected to the inner wall of the protective plate 2, which facilitates the unfolding and retraction of the protective components when needed; the second spring 15 is in contact with the inner wall of the protective plate 2, and during the unfolding and retraction of the extension plate 14, the second spring 15 stores and releases potential energy through contact with the inner wall of the protective plate 2, thereby driving the movement of the extension plate 14.

[0032] The outer surface of spring 9 is in contact with the outer surface of rotating plate 5 and the outer surface of fixed frame 3. Spring 9, in contact with the outer surfaces of rotating plate 5 and fixed frame 3, stores potential energy when rotating plate 5 is deployed. When rotating plate 5 needs to be retracted, spring 9 releases its potential energy, pushing rotating plate 5 back to its original position. The contact between spring 9 and rotating plate 5 and fixed frame 3 ensures the transmission of force and the stability of rotating plate 5's retraction.

[0033] The working process of this utility model is as follows:

[0034] First, after moving the frame 1 to a suitable position, the two limiting posts 11 are lifted. At this time, the limiting posts 11 are no longer engaged with the extension plate 14. The rotating plate 5 will be reset into the stabilizing groove 12 due to the potential energy released by the spring 9 in the slider 10. During this process, the rotating plate 5 will rotate in the locking pin 4 connected to the fixed frame 3, while the support rod 7 rotates on the surface of the locking post 6. In this way, the rotating plate 5 is fully retracted and the two extension plates 14 will move, extending the area to prevent damage from spring collapse and greatly protecting the safety of the staff.

[0035] During the movement of the extension plates 14, two of the extension plates 14 will be subjected to the force of the spring 15 connected to the limiting plate 13, causing the two extension plates 14 to leave the interior of the protective plate 2, increasing the protective area. After the work is completed, the limiting post 11 can be used to fix the extension plate 14 to the extension plate 14 through the relationship between the limiting post 11 and the extension plate 14. Then, by moving the protective plate 2 in the position of the frame 1, the area can be reduced while facilitating storage and improving space utilization.
