Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing rings, and more particularly to an O-type sealing ring disassembly device. Background Art
[0002] An O-ring is a rubber sealing ring with a circular cross-section. It is a commonly used sealing element. It is widely used in various fields due to its simple structure, easy installation, and reliable sealing performance. During the long-term use of equipment, the O-ring may need to be replaced or repaired regularly due to wear and aging. Therefore, the removal of the O-ring has become an important link.
[0003] In the prior art, the O-ring removal process mainly relies on manual labor with the help of a screwdriver or hook to hook the O-ring out of the hole. During the removal process, when the hook or screwdriver is inserted into the bottom of the O-ring to hook the O-ring, its sharp part may scrape the side of the O-ring, thereby increasing the wear of the O-ring. Therefore, a new solution is needed to reduce the wear of the O-ring caused by tools during the removal process. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an O-ring removal device, which reduces the probability of wear on the O-ring when the hook is inserted by arranging baffles on both sides of the hook.
[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: the O-ring removal device includes a handle and a hook fixedly connected to each other, and baffles fixedly connected to each other are provided on both sides of the hook. The side of the baffle close to the handle is fixedly connected to a connecting rod, and the end of the connecting rod close to the handle is slidably connected to a pressing plate for supporting the handle. When the contact area between the pressing plate and the handle is zero, the hook slides downward and extends out of the baffle.
[0006] The utility model is further configured as follows: the two baffles are connected by a fixing strip, and a moving hole having the same diameter as the hook is opened on the fixing strip.
[0007] The utility model is further configured as follows: a T-shaped sliding groove is provided on the lower surface of the pressing plate, the connecting rod is slidably connected to the inner wall of the sliding groove, and the outer surface of the upper end of the connecting rod is fitted with the inner wall of the sliding groove.
[0008] The utility model is further configured as follows: a through slot is provided on one end of the pressing plate close to the handle and passes through the thickness direction of the pressing plate, and the hook passes through the through slot and is fixedly connected to the handle.
[0009] The utility model is further configured such that: the distance between the handle and the upper surface of the baffle is greater than the distance between the hook and the bottom surface of the baffle.
[0010] The utility model is further configured as follows: the end of the baffle away from the handle is configured as an arc, and the cross-sectional area of the end of the baffle away from the handle is smaller than the cross-sectional area of the other end.
[0011] In summary, the utility model has the following beneficial effects: the O-ring disassembly device is provided with baffles on both sides of the hook, and the hook is stored between the two baffles in the initial state, reducing the probability of scratching the surface of the O-ring when the disassembly device is inserted between the O-ring and the object. At the same time, a pressing plate supporting the handle is provided on the baffle, so that the position of the hook can be fixed during the insertion process, so that the hook will not slip out from between the two baffles. At the same time, the baffle can be inserted by applying pressure to the pressing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0017] The O-ring removal device, such as Figure 1-Figure 3 As shown, it includes a handle 1 and a hook 2 fixedly connected to each other. When removing the O-ring, the operator holds the handle 1 and uses the hook 2 to squeeze the O-ring and insert it between the O-ring and the device. Then, the bent part of the hook 2 is turned under the O-ring and a pulling force is applied upward to pull the O-ring out. Baffles 3 bonded to each other are provided on both sides of the hook 2. When the O-ring needs to be removed, the O-ring can be squeezed with the baffle 3 first. When the baffle 3 is inserted into the bottom surface, the hook 2 is rotated to enter under the O-ring, reducing the probability of wear on the O-ring during the squeezing and insertion process.
[0018] Such as Figure 1As shown, the side of the baffle 3 close to the handle 1 is fixedly connected to the connecting rod 4, and the end of the connecting rod 4 close to the handle 1 is slidably connected to a pressing plate 5 for supporting the handle 1. In the initial state, the upper surface of the pressing plate 5 is against the lower surface of the handle 1, and the pressing plate 5 provides a supporting force for the handle 1. In the initial state, the bent portion of the hook 2 is received between the two baffles 3, reducing the probability of the hook 2 sliding out of the baffle 3 and contacting the O-ring during the downward insertion process, causing wear of the O-ring. The operator applies pressure on the upper surface of the pressing plate 5 to insert the baffle 3 between the O-ring and the device, and then applies a pulling force to the pressing plate 5 to move the pressing plate 5 on the connecting rod 4 away from the handle 1, thereby eliminating the supporting force below the handle 1. The operator applies force to the handle 1 to make the hook 2 reach the bottom and rotate into the bottom of the O-ring and apply a pulling force upward to pull the O-ring out.
[0019] like Figure 2 As shown, the two baffles 3 are connected by a fixing bar 6, and a movable hole 7 with the same diameter as the hook 2 is opened on the fixing bar 6. The movable hole 7 not only provides space for the up and down movement of the hook 2, but also ensures that the hook 2 will not move in the baffle 3, so that the hook 2 and the handle 1 can move parallel to the baffle 3 on the fixed track, and at the same time can cooperate with the pressing plate 5 above so that the pressing plate 5 can stably restrict the handle 1.
[0020] like Figure 3 As shown, a T-shaped sliding groove 8 is provided on the lower surface of the pressing plate 5, and the connecting rod 4 is slidably connected to the inner wall of the sliding groove 8. The outer surface of the upper end of the connecting rod 4 fits with the inner wall of the sliding groove 8. The setting of the sliding groove 8 enables the pressing plate to slide in a direction perpendicular to the connecting rod 4. In the initial state, the pressing plate 5 has a supporting effect on the handle 1. When the pressing plate 5 slides on the connecting rod 4 so that the contact area between the pressing plate 5 and the handle 1 is zero, the restriction of the pressing plate 5 on the handle 1 disappears, and the handle 1 can move freely up and down. The sliding groove 8 and the upper end of the connecting rod 4 are both set to T-shape, so that the connecting rod 4 will not slide into the groove 8, and the connecting rod 4 can be stably connected to the pressing plate 5.
[0021] like Figure 3 As shown, a through slot 9 is provided at one end of the pressing plate 5 close to the handle 1, which runs through the thickness direction of the pressing plate 5. The hook 2 passes through the through slot 9 and is bonded to the handle 1. The axis of symmetry in the width direction of the through slot 9 and the central axis of the hook 2 perpendicular to the connecting rod 4 are on the same plane. The width of the through slot 9 is smaller than the diameter of the handle 1. The connecting section of the hook 2 slides on the inner wall of the through slot 9. When the connecting section of the hook 2 slides inside the through slot 9, the pressing plate 5 provides supporting force to the handle 1. When the hook 2 slides out of the through slot 9, the supporting force of the pressing plate 5 on the handle 1 disappears, so that the handle 1 can move up and down.
[0022] like Figure 1-Figure 3As shown, the distance between the handle 1 and the upper surface of the baffle 3 is greater than the distance between the hook 2 and the ground of the baffle 3, which can ensure that the handle 1 can move downward a distance sufficient to allow the bend of the hook 2 to extend out of the baffle and into the bottom of the O-ring, so that the operator's pulling force can be applied to the O-ring, thereby pulling the O-ring out. The baffle 3 is arranged in an arc shape at one end away from the handle 1 and the side away from the hook 2. The cross-sectional area of the end of the baffle 3 away from the handle 1 is smaller than the cross-sectional area of the other end. The smaller area of the bottom of the baffle 3 can make the baffle 3 less obstructed when entering between the O-ring and the equipment, thereby better enabling the device to be inserted between the O-ring and the equipment to disassemble the O-ring.
[0023] Working principle: When using the O-ring removal device, the baffle squeezes the O-ring and inserts it between the O-ring and the equipment, and applies pressure to the pressing plate 5 to make the baffle reach the bottom of the gap. The pressing plate 5 is then slid on the connecting rod 4 to eliminate the supporting force of the pressing plate 5 on the handle 1. The operator applies force to the handle 1 to make the hook 2 move downward to the bottom of the gap and rotates the handle 1 to make the hook 2 rotate out of the baffle and extend into the bottom of the O-ring. The pulling force applied by the operator to the handle 1 is transmitted to the O-ring through the hook 2 to remove the O-ring.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
