Description

Technical Field

[0001] The utility model relates to the technical field of spring energy storage rings, in particular to a spring energy storage ring with an internal structure anti-breaking function. Background Art

[0002] The spring energizer is a high performance seal consisting of a jacket made of PTFE or other polymeric material and a corrosion resistant metal spring.

[0003] After searching, a Chinese patent with publication number CN218207775U discloses a metal spring energy storage seal ring, including a seal ring body, a first card slot is provided on the inner wall of the seal ring body, and a limit slot is provided at the opening of the first card slot, a metal spring part is arranged in the first card slot, and an elastic baffle is arranged in the limit slot, an annular protrusion is arranged on the upper surface of the seal ring body, and a second card slot is provided on the side wall of the seal ring body, and a sealing ring is arranged in the second card slot. The utility model can achieve the purpose of reducing the use cost of the device and improving the sealing effect of the device by opening a second card slot on the outer side wall of the seal ring body, arranging a sealing ring in the second card slot, and arranging a limit slot at the opening of the first card slot, and arranging an elastic baffle in the limit slot, and using a detachable seal ring and an elastic baffle with high elasticity.

[0004] Although the above scheme can reduce the cost of using the device and improve the sealing effect of the device, the spring energy storage sealing ring in the above patent does not have the effect of preventing breaking. Generally, spring energy storage sealing rings are often used in some high-pressure environments. If they are in a high-pressure state for a long time, the spring energy storage sealing ring is prone to breakage. For this reason, we provide a spring energy storage ring with an internal structure anti-breaking function to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that the spring energy storage ring in the prior art does not have the anti-breaking effect, and provides a spring energy storage ring with an internal structure anti-breaking function.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spring energy storage ring with an internal structure anti-breakage function, comprising a heat-resistant and wear-resistant outer shell, the inner wall of the heat-resistant and wear-resistant outer shell is fixedly connected to the outer circumferential surface of the first elastic reinforcement layer plate, the inner wall of the first elastic reinforcement layer plate is fixedly connected to the outer circumferential surface of the second elastic reinforcement layer plate, the inner wall of the second elastic reinforcement layer plate is fixedly connected to the outer circumferential surface of the I-shaped limiting clamping ring, the groove on the top of the I-shaped limiting clamping ring is clamped with the outer circumferential surface of the first spring body, and the close fit between the components can effectively achieve the effect of preventing breakage.

[0007] Furthermore, there are two groups of the first spring bodies, and the two groups of first spring bodies are respectively clamped in the grooves on both sides of the I-shaped limiting clamp ring. The setting of the I-shaped limiting clamp ring can effectively limit the first spring body.

[0008] Furthermore, the inner wall of the I-shaped limit clamp is fixedly connected to one side of the first protective base, the other side of the first protective base is fixedly connected to one end of the first limit rod, and the outer circumferential surface of the first limit rod is fixedly connected to the groove in the middle of the U-shaped limit clamp. The setting of the U-shaped limit clamp avoids separation of the components when they move, thereby avoiding the situation where the expected effect cannot be achieved.

[0009] Furthermore, the outer circumferential surface of the first limiting single rod is slidably connected to the groove in the middle of the position control protective shell, one side of the position control protective shell is fixedly connected to one end of the second limiting single rod, and the other end of the second limiting single rod is fixedly connected to the inner wall of the I-shaped limiting clamp. The setting of the second limiting single rod can effectively support other components and prevent other components from shaking.

[0010] Furthermore, the inner wall of the position control protective shell is fixedly connected to the outer circumferential surface of the blocking and limiting cylinder, one end of the blocking and limiting cylinder is fixedly connected to one end of the first buffer spring, and the other end of the first buffer spring is fixedly connected to the other end of the first limiting single rod. The setting of the first limiting single rod can effectively make other components move along a predetermined route.

[0011] Furthermore, there are two groups of the first buffer springs, which are symmetrically distributed on both sides of the blocking limit cylinder. Both groups of the first buffer springs are located on the inner wall of the position control protective shell. The first buffer springs are existing technology and will not be described in detail.

[0012] Furthermore, the top of the first elastic reinforcement layer is fixedly connected to the bottom of the first anti-wear layer, and the outer circumferential surface of the first anti-wear layer is fixedly connected to the inner wall of the heat-resistant and wear-resistant outer shell. The setting of the heat-resistant and wear-resistant outer shell greatly improves the practicality of the spring energy storage ring and increases its service life.

[0013] Furthermore, the outer circumferential surface of the heat-resistant and wear-resistant shell is fixedly connected to one side of the first anti-wear pad. There are four groups of first anti-wear pads, and the four groups of first anti-wear pads are evenly distributed on the outer circumferential surface of the heat-resistant and wear-resistant shell. The setting of the first anti-wear pads can effectively reduce the damage caused by friction to the spring energy storage ring itself.

[0014] Compared with the prior art, the spring energy storage ring with an internal structure anti-breaking function has the following beneficial effects:

[0015] 1. The utility model can effectively achieve the effect of preventing breakage through the arrangement of the heat-resistant and wear-resistant outer shell, the first elastic reinforcement layer plate, the second elastic reinforcement layer plate, the I-shaped limit clamp ring, and the first spring body. Even if the spring energy storage ring is in a high-pressure working environment for a long time, it still maintains its original shape for movement and is not prone to breakage.

[0016] 2. The utility model can effectively provide auxiliary support for achieving the anti-breakage effect through the arrangement of the first limiting single rod, the U-shaped limiting splint, the control protective shell, the second limiting single rod, the blocking limiting cylinder, the first buffer spring, the first anti-wear layer, the first anti-wear pad, and the first protective base, thereby further strengthening the stability of the spring energy storage ring and enhancing the practicability of the spring energy storage ring.

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] See also Figure 1The present embodiment proposes a spring energy storage ring with an internal structure anti-breaking function, including a heat-resistant and wear-resistant outer shell 1. The setting of the heat-resistant and wear-resistant outer shell 1 can reduce the loss of the spring energy storage ring during operation. The heat-resistant and wear-resistant outer shell 1 is elastic. The outer circumferential surface of the heat-resistant and wear-resistant outer shell 1 is fixedly connected to one side of the first anti-wear pad 13. There are four groups of first anti-wear pads 13, and the four groups of first anti-wear pads 13 are evenly distributed on the outer circumferential surface of the heat-resistant and wear-resistant outer shell 1. The purpose of setting multiple groups of first anti-wear pads 13 is to reduce the area of ​​direct contact between the external machine and the spring energy storage ring, thereby ensuring that the spring energy storage ring always maintains smooth movement.

[0024] See also Figure 1 and Figure 2 The inner wall of the heat-resistant and wear-resistant outer shell 1 is fixedly connected to the outer circumferential surface of the first elastic reinforcing layer plate 2, the top of the first elastic reinforcing layer plate 2 is fixedly connected to the bottom of the first wear-resistant layer plate 12, and the outer circumferential surface of the first wear-resistant layer plate 12 is fixedly connected to the inner wall of the heat-resistant and wear-resistant outer shell 1. The setting of the first wear-resistant layer plate 12 can effectively avoid the problem that the internal components of the spring energy storage ring are affected by external factors.

[0025] See also Figure 2 The inner wall of the first elastic reinforced layer plate 2 is fixedly connected to the outer circumferential surface of the second elastic reinforced layer plate 3, and the inner wall of the second elastic reinforced layer plate 3 is fixedly connected to the outer circumferential surface of the I-shaped limit snap ring 4. The first elastic reinforced layer plate 2, the second elastic reinforced layer plate 3 and the I-shaped limit snap ring 4 are tightly combined to avoid detachment between the components, and the I-shaped limit snap ring 4 is elastic.

[0026] See also Figure 3 The inner wall of the I-shaped limit clamp 4 is fixedly connected to one side of the first protective base 14, and the other side of the first protective base 14 is fixedly connected to one end of the first limit single rod 6. The outer circumferential surface of the first limit single rod 6 is slidably connected to the groove in the middle of the position control protective shell 8. The setting of the first limit single rod 6 realizes contraction under the joint action of the position control protective shell 8.

[0027] See also Figure 3 The inner wall of the position control protection shell 8 is fixedly connected to the outer circumferential surface of the blocking and limiting cylinder 10, and one end of the blocking and limiting cylinder 10 is fixedly connected to one end of the first buffer spring 11. There are two groups of first buffer springs 11, and the two groups of first buffer springs 11 are symmetrically distributed on both sides of the blocking and limiting cylinder 10. Both groups of first buffer springs 11 are on the inner wall of the position control protection shell 8. The purpose of setting multiple groups of first buffer springs 11 is to increase fault tolerance and prevent the spring energy storage ring from being affected by external force. When the shape is changed, excessive squeezing between components may damage the spring energy storage ring.

[0028] See also Figure 3The other end of the first buffer spring 11 is fixedly connected to the other end of the first limiting single rod 6, one side of the position control protection shell 8 is fixedly connected to one end of the second limiting single rod 9, and the other end of the second limiting single rod 9 is fixedly connected to the inner wall of the I-shaped limiting clamp 4. The setting of the second limiting single rod 9 can effectively limit the position control protection shell 8 and prevent the position control protection shell 8 from shaking.

[0029] See also Figure 2 , Figure 3 and Figure 4 The outer circumferential surface of the first limiting single rod 6 is fixedly connected to the groove in the middle of the U-shaped limiting clamp 7, and the groove at the top of the I-shaped limiting clamp 4 is clamped with the outer circumferential surface of the first spring body 5. There are two groups of first spring bodies 5, and the two groups of first spring bodies 5 are respectively clamped in the grooves on both sides of the I-shaped limiting clamp 4. The purpose of setting multiple groups of first spring bodies 5 is to make the spring energy storage ring more stable and to restore the original state when deformation occurs.

[0030] Working principle: After the spring energy storage ring is installed in the specified position, the external force acts on the spring energy storage ring, and firstly, the force will be applied to the heat-resistant and wear-resistant shell 1 through the first anti-wear pad 13. Under the interaction of the first elastic reinforcement layer 2, the second elastic reinforcement layer 3, the I-shaped limit snap ring 4 and the first spring body 5, the heat-resistant and wear-resistant shell 1 can be restored to its original state. At the same time, the I-shaped limit snap ring 4 will also transmit the force to the first protective base 14. Under the action of the elasticity of the first buffer spring 11 itself, the first limit single rod 6 is pushed to slide in the control protective shell 8 with the blocking limit cylinder 10 as the fulcrum. Under the action of the U-shaped limit splint 7, it can ensure that the first limit single rod 6 pushes the first protective base 14 to act on the I-shaped limit snap ring 4, so as to avoid excessive deformation of the I-shaped limit snap ring 4. Under the close cooperation between the components, the spring energy storage ring can effectively achieve the effect of preventing breaking, so that the spring energy storage ring can maintain efficient movement for a long time.
