Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a novel anti-impact handle valve. Background Technology

[0002] A handle valve is a control device that uses a handle to rotate the valve stem to open and close the valve. It is widely used in water conservancy, chemical industry, machinery and other fields.

[0003] Based on the above, the inventors have discovered the following problems: Currently, the handle and valve stem of existing handle valves are usually directly fixedly connected, which does not have an impact resistance function. When the handle is subjected to external impact, the impact force will be directly transmitted to the connection between the handle and the valve stem, which can easily lead to loosening, breakage and other damage at the connection, affecting the normal use of the handle valve, reducing its service life, and may even cause safety accidents.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a new type of impact-resistant handle valve in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a novel impact-resistant handle valve to solve the problem mentioned in the background art, where the handle and valve stem of the existing handle valve are usually directly fixedly connected, which does not have an impact resistance function. When the handle is subjected to external impact, the impact force will be directly transmitted to the connection between the handle and the valve stem, which can easily lead to loosening, breakage and other damage at the connection, affecting the normal use of the handle valve, reducing its service life, and even potentially causing safety accidents.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A novel impact-resistant handle valve includes a valve body. A first connecting ring is fixedly connected to the outer side of the top of the valve body. A second connecting ring is provided at the top of the first connecting ring. Buffer mechanisms are installed on all four sides of the top of the second connecting ring. A protective ring is installed at the top of each buffer mechanism. Plug seats are installed on all four sides of the top of the first connecting ring. Plug connectors are installed on all four sides of the bottom of the second connecting ring. The outer bottom end of each plug connector is inserted into the inner side of the plug seat. Positioning mechanisms are embedded in the bottom ends of both sides of each plug connector. Each positioning mechanism includes a protrusion. Grooves are formed on both sides of the inner surface of the plug seat. One end of each protrusion is engaged with the inner side of the groove.

[0008] Furthermore, the buffer mechanism includes a damper, the top end of which is fixedly connected to the bottom end of the protective ring, the bottom end of which is fixedly connected to the top end of the second connecting ring, and a buffer spring is sleeved on the outside of the damper.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, by sleeved with a buffer spring on the outside of the damper, the spring absorbs energy during impact and buffers the oscillation through the damper, converting the instantaneous impact force into a slow deformation force, effectively weakening the influence of external force on the valve body.

[0010] Furthermore, a first connecting plate is installed at the bottom end of the buffer spring, and the bottom end of the first connecting plate is fixedly connected to the top end of the second connecting ring.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by installing a first connecting plate at the bottom of the buffer spring, the contact area between the spring and the second connecting ring is increased, so that the spring is subjected to uniform force.

[0012] Furthermore, a second connecting plate is installed at the top of the buffer spring, and the top of the second connecting plate is fixedly connected to the bottom of the protective ring.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by installing a second connecting plate at the top of the buffer spring, the connection stability between the spring and the protective ring is enhanced.

[0014] Furthermore, the connector has an internal cavity, and both sides of the cavity are slidably connected to limit plates. The other end of the protrusion is fixedly connected to one side of the limit plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by slidingly connecting limit plates on both sides of the cavity, the movement trajectory of the protrusion is restricted, preventing the protrusion from shifting when engaging or disengaging.

[0016] Furthermore, a partition is installed in the middle of the inner side of the cavity, and springs are installed on both sides of the partition. One end of the spring is fixedly connected to the other side of the limiting plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, by installing springs on both sides of the partition, a continuous elastic force is provided to the limiting plate and the protrusion, ensuring that the protrusion is tightly engaged in the groove.

[0018] Furthermore, one end of the protrusion is arc-shaped.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, by making one end of the protrusion arc-shaped, it can automatically squeeze and shrink when the connector is inserted into the connector socket, reducing assembly resistance and facilitating quick docking. During disassembly, the protrusion can also be easily pushed out of the groove by external force, improving the convenience of disassembly and assembly and reducing maintenance difficulty.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This impact-resistant novel handle valve achieves rapid assembly of the first and second connecting rings by inserting the outer bottom end of the plug and the inner side of the plug seat. The protrusion of the positioning mechanism is engaged in the groove, enhancing connection stability and preventing detachment. The protective ring supported by the buffer mechanism can absorb external impact force, reducing damage to the handle valve when impacted. A buffer spring is sleeved on the outer side of the damper. During impact, the spring absorbs energy and buffers the oscillation through the damper, converting the instantaneous impact force into a slow deformation force, effectively weakening the impact of external force on the valve body. A first connecting plate is installed at the bottom end of the buffer spring, increasing the contact area between the spring and the second connecting ring, making the spring force evenly distributed. A second connecting plate is installed at the top to enhance the connection stability between the spring and the protective ring. Limiting plates are slidably connected to both sides of the cavity to restrict the movement trajectory of the protrusion and prevent it from shifting when engaging or disengaging. Springs are installed on both sides of the partition to provide continuous elastic force to the limiting plates and the protrusion, ensuring that the protrusion is tightly engaged in the groove. One end of the protrusion is arc-shaped, which allows it to automatically compress and shrink when the connector is inserted into the connector socket, reducing assembly resistance and facilitating quick docking. During disassembly, the protrusion can also be easily pushed out of the groove by external force, improving the convenience of disassembly and assembly and reducing maintenance difficulty. This utility model can effectively achieve impact resistance and prevent the handle from being damaged by external impact, and has high practical value. Attached Figure Description

The outer bottom of the plug connector 4 is plugged into the inner side of the plug seat 3, and the two sides of the plug connector 4 are... The bottom end is equipped with a positioning mechanism 5, which includes a protrusion 501. The inner sides of the plug seat 3 are provided with grooves 301. One end of the protrusion 501 is engaged with the inner side of the groove 301. The first connecting ring 2 and the second connecting ring 6 are quickly assembled by inserting the outer bottom end of the plug 4 into the inner side of the plug seat 3. The protrusion 501 of the positioning mechanism 5 is engaged in the groove 301 to enhance the connection stability and prevent it from falling off. The protective ring 7 supported by the buffer mechanism 8 can absorb external impact force and reduce the damage to the handle valve when it is hit.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5The buffer mechanism 8 includes a damper 801, with the top end of the damper 801 fixedly connected to the bottom end of the protective ring 7, and the bottom end of the damper 801 fixedly connected to the top end of the second connecting ring 6. A buffer spring 804 is sleeved on the outside of the damper 801, and a first connecting plate 802 is installed at the bottom end of the buffer spring 804. The bottom end of the first connecting plate 802 is fixedly connected to the top end of the second connecting ring 6, and a second connecting plate 803 is installed at the top end of the buffer spring 804. The top end of the second connecting plate 803 is fixedly connected to the bottom end of the protective ring 7. With the buffer spring 804 sleeved on the outside of the damper 801, the spring absorbs energy during impact and buffers the oscillation through the damper, converting the instantaneous impact force into a slow deformation force, effectively weakening the influence of external force on the valve body 1. The first connecting plate 802 installed at the bottom end of the buffer spring 804 increases the contact area between the spring and the second connecting ring 6, making the spring more evenly stressed. The second connecting plate 803 installed at the top end of the buffer spring 804 enhances the connection stability between the spring and the protective ring 7.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 The connector 4 has an internal cavity 401. Limiting plates 503 are slidably connected to both sides of the cavity 401. The other end of the protrusion 501 is fixedly connected to one side of the limiting plate 503. A partition 502 is installed in the middle of the inner side of the cavity 401. Springs 504 are installed on both sides of the partition 502. One end of each spring 504 is fixedly connected to the other side of the limiting plate 503. One end of the protrusion 501 is arc-shaped. The movement of the protrusion 501 is restricted by the slidable connection of the limiting plates 503 to both sides of the cavity 401. The movement trajectory prevents the protrusion 501 from shifting when engaging or disengaging. Springs 504 are installed on both sides of the partition 502 to provide continuous elastic force to the limiting plate 503 and the protrusion 501, ensuring that the protrusion 501 is tightly engaged in the groove 301. One end of the protrusion 501 is arc-shaped, which allows it to automatically squeeze and retract when the connector 4 is inserted into the connector 3, reducing assembly resistance and facilitating quick docking. During disassembly, the protrusion 501 can also be easily pushed out of the groove 301 by external force, improving the convenience of disassembly and assembly and reducing the difficulty of maintenance.

[0033] Specifically, the working principle of this new type of impact-resistant handle valve is as follows: During use, the first connecting ring 2 and the second connecting ring 6 are quickly assembled by inserting the outer bottom end of the connector 4 into the inner side of the connector 3. The protrusion 501 of the positioning mechanism 5 is engaged with the groove 301, enhancing connection stability and preventing detachment. The protective ring 7 supported by the buffer mechanism 8 absorbs external impact force, reducing damage to the handle valve when impacted. A buffer spring 804 is sleeved on the outer side of the damper 801. During impact, the spring absorbs energy and buffers the oscillation through the damper, converting the instantaneous impact force into a slow deformation force, effectively weakening the impact of external force on the valve body 1. A first connecting plate 802 is installed at the bottom end of the buffer spring 804, increasing the contact area between the spring and the second connecting ring 6, making the spring more evenly stressed. A second connecting plate 802 is installed at the top end of the buffer spring 804. The disc 803 enhances the connection stability between the spring and the protective ring 7. Limiting plates 503 are slidably connected to both sides of the cavity 401 to restrict the movement trajectory of the protrusion 501 and prevent it from shifting during engagement or disengagement. Springs 504 are installed on both sides of the partition 502 to provide continuous elastic force to the limiting plates 503 and the protrusion 501, ensuring that the protrusion 501 is tightly engaged in the groove 301. The protrusion 501 has an arc-shaped end, allowing it to automatically compress and retract when the connector 4 is inserted into the connector 3, reducing assembly resistance and facilitating quick connection. During disassembly, external force can easily push the protrusion 501 out of the groove 301, improving ease of assembly and disassembly and reducing maintenance difficulty. This invention effectively achieves impact resistance, preventing damage to the handle from external impacts and has high practical value.
