Abstract
Description
Technical Field
[0001] This utility model relates to the field of launch vehicle technology, specifically to a device for removing a gasket from a connector nozzle. Background Technology
[0002] The launch vehicle's temperature sensor measures temperature by sealing it to the pipeline nozzle via a sensor connector. A sealing gasket is placed at the sealed end between the temperature sensor and the pipeline nozzle. After temperature measurement, when disassembling the temperature sensor and pipeline nozzle, the gasket may become stuck at the sealed end. Currently, the gasket is mainly removed by prying it off with fingers or using a screwdriver. Prying it off with fingers is difficult and can easily scratch the fingers, making removal difficult. Using a screwdriver to remove the gasket makes it difficult to judge the depth of removal, potentially damaging the sealing surface and resulting in substandard sealing performance.
[0003] In summary, the existing technology has the following problems: after the temperature measurement is completed, removing the gasket from the sealing end of the connector can easily damage the sealing surface, resulting in unqualified sealing performance. Utility Model Content
[0004] This utility model provides a device for removing a gasket from a connector nozzle. The technical problem it solves is how to remove the gasket from the sealing end of the connector nozzle after temperature measurement is completed, while ensuring that the sealing performance is not compromised.
[0005] To achieve the above objectives, this utility model proposes a device for removing a gasket from a connector nozzle, comprising:
[0006] A housing with a top opening;
[0007] A top rod that can move up and down and is disposed in the opening of the housing;
[0008] A pry bar that can compress a gasket and create a gap between the gasket and the connector nozzle for removing the gasket, the pry bar being movably disposed within the housing and within the downward stroke range of the top rod;
[0009] A pull plate, which is hinged to the pry bar and extends out of the housing.
[0010] Specifically, the housing has a lower end connected to the connector nozzle and an upper end connected to the top rod; the pry bar is disposed in the housing and slides in contact with the housing; the side wall of the housing has a window through which the pull plate passes; the pull plate is connected to the pry bar through the window.
[0011] Specifically, the pry bar is provided with support end handles on both sides, and the side wall of the housing is also provided with support holes for supporting the support end handles;
[0012] The support end handle is movably mounted in the support hole, optimizing force transmission and structural stability. The support hole provides radial constraint to the pry bar, fixing its position within the housing and preventing lateral shifting or tilting during stress. This ensures the force exerted by the pry bar on the gasket is always transmitted in the predetermined direction, reducing accidental damage to the sealing surface caused by pry bar movement.
[0013] Specifically, the support holes are arranged symmetrically. The symmetrical arrangement of the support holes balances the force on both sides of the pry bar, preventing radial tilting due to excessive force on one side, and ensuring that the force on the gasket is always transmitted in the preset direction, thus structurally eliminating the risk of sealing surface damage caused by off-center loading.
[0014] Specifically, the push rod is threadedly connected to the housing. It is detachable for easy maintenance and replacement. The housing is threadedly connected to the connecting nozzle. The connection is secure and prevents loosening or displacement.
[0015] Specifically, an elastic support block is provided inside the support hole; the support end handle is mounted on the elastic support block. The support block forms a stable force fulcrum, avoiding local overload. The elastic support block, through its own elasticity, causes the pry bar to complete downward displacement.
[0016] Specifically, the top of the pry bar is equipped with a roller for contacting the bottom of the push rod. This roller contact ensures stable contact, preventing jamming and guaranteeing the pry bar rotates along a preset trajectory, indirectly improving the accuracy of subsequent shim operations.
[0017] Specifically, the device also includes a storage slot for accommodating the hooked workpiece, the storage slot being disposed on the housing. This facilitates the easy access to the hooked workpiece.
[0018] Specifically, a connecting lug is provided at one end of the pry bar near the roller, and the pull plate is rotatably connected to the pry bar through the connecting lug. The connecting lug provides a precise and stable connection point for the pull plate.
[0019] Specifically, the device is used to remove the gasket from the pipeline connector of the launch vehicle, and the pipeline connector is sealed to the connector of the temperature sensor of the launch vehicle.
[0020] The beneficial technical effects of the above technical solution are as follows:
[0021] The pry bar of this gasket removal device is positioned by the housing and the connecting nozzle. It applies a controllable peeling force to the gasket using the lever principle, avoiding direct violent prying that could scratch or deform the sealing surface of the connecting nozzle. The linkage structure between the pull plate and the pry bar simplifies the force application method. The gasket can be efficiently removed by simply applying pressure with the top rod in conjunction with the pull plate operation, reducing the difficulty of operation.
[0022] The lower end of the housing connects to the nozzle to achieve precise alignment between the device and the workpiece, preventing deviation during operation; the side window provides movement space for the pull plate, and the contact between the roller and the push rod reduces friction, ensuring that the axial force applied by the push rod is stably transmitted to the pry bar, so that the gasket is subjected to uniform force and the risk of damage to the sealing surface is reduced.
[0023] While ensuring that the sealing performance of the connector is not damaged, the gasket can be easily and safely removed, solving the technical pain point of removing the gasket from the sealing end after temperature measurement. Attached Figure Description

[0034] 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.
[0035] This utility model provides a device for removing a gasket from a connector nozzle, such as... Figure 1 As shown, it includes: a push rod 1, a housing 2, a pull plate 3, a pry bar 4, a roller 5, and a workpiece hook 9;
[0036] Among them, such as Figure 2 , Figure 6 As shown, the lower end of the housing 2 is connected to the connector 6, and the upper end of the housing 2 is connected to the push rod 1; preferably, the push rod 1 is threadedly connected to the housing 2, and the housing 2 is threadedly connected to the connector 6. The threaded connection allows for smooth application of axial force by rotating the push rod. The pry bar 4 is disposed in the housing 2 and slides in contact with the housing 2; the pry bar 4 can compress the gasket 7 and create a gap between the gasket 7 and the connector 6, allowing the gasket 7 to be removed. The side wall of the housing 2 has a window 22 through which a pull plate 3 partially passes; the pull plate 3 is connected to the pry bar 4 through the window 22; as shown... Figure 4 As shown, the top of the pry bar 4 is equipped with a roller 5 for contacting the bottom of the push rod 1. The low-resistance characteristic of rolling friction makes the action of pressing down the push rod or rotating the pry bar smoother. The pry bar is positioned by the housing and the connector, applying a controllable peeling force to the gasket, avoiding direct and violent prying that could scratch or deform the sealing surface of the connector. The contact between the roller and the push rod reduces friction, ensuring that the axial force applied by the push rod is stably transmitted to the pry bar, making the gasket evenly stressed and reducing the risk of damage to the sealing surface.
[0037] like Figure 5 As shown, the upper end of the housing 2 is provided with an internal thread, the pitch of which is 1.0–2.0 mm. The threaded connection allows for smooth application of axial force by rotating the push rod. Combined with the fine pitch of 1.0–2.0 mm, the threaded connection's fine adjustment capability enables precise control of the axial force during gasket removal, ensuring undamaged sealing performance and improving operational controllability. Preferably, the internal thread pitch is 1.5 mm. This allows for extremely small feed rate control, meaning the push rod moves only 1.5 mm per revolution. This allows for precise adjustment of the pressure on the pry bar, preventing damage to the gasket or sealing surface due to excessive force, and is particularly suitable for the delicate operations required when removing gaskets that are tightly attached to the sealing end.
[0038] like Figure 3As shown, the side wall of the housing 2 is also provided with support holes 21 for supporting the pry bar 4; the pry bar 4 is installed in the housing 2 via the support holes 21. There are two support holes 21 arranged symmetrically, and a support block 8 is installed inside each support hole 21. Support handles 41 are provided on both sides of the pry bar 4, and the support handles 41 are installed in the support holes 21, as shown. Figure 8 As shown, the support handle 41 is cylindrical. Two symmetrically arranged support holes 21 provide bilateral radial constraints for the pry bar 4, forming a stable two-point positioning support structure. This spatially restricts the lateral offset or torsion of the pry bar, ensuring that its movement trajectory always follows a preset direction (such as perpendicular to the nozzle sealing surface), avoiding pry bar tilting due to unilateral support, and fundamentally reducing the risk of accidental scratches on the sealing surface. The support handle 41 is mounted on the support block 8. The support block 8 can be a rubber block, glued to the housing 2. The rubber block is elastic, forming a stable force fulcrum and preventing local overload. The elastic support block, through its own elasticity, causes the pry bar to complete downward displacement. Furthermore, the support block 8 absorbs the impact force generated during pry bar movement, preventing rigid collisions between the support handle 41, the support block 8, and the housing 2. This prevents scratches and deformation of the pry bar or housing due to long-term hard contact, while reducing vibration and noise during operation and improving the smoothness of device use.
[0039] The gasket removal device of this utility model also includes a receiving groove for accommodating the hooked workpiece 9. The receiving groove is disposed on the housing 2 and is perpendicular to the upper end face of the housing 2. After the pry bar 4 peels off the gasket, the hooked workpiece 9 is taken out from the receiving groove, and then the deformed gasket is hooked out.
[0040] A connecting lug 42 is provided at the end of the pry bar 4 near the roller 5. The pull plate 3 is rotatably connected to the pry bar 4 via the connecting lug 42. When the pull plate drives the pry bar to move, the two can flexibly rotate relative to each other around the pin or connecting piece of the connecting lug 42, adapting to the angle change of the pry bar 4 under the pressure of the top rod 1, avoiding the unsmooth movement caused by rigid connection, and ensuring that the pry bar 4 can smoothly complete the peeling action when removing the gasket.
[0041] In one implementation, the housing 2 is screwed into the connector 6, and then tightened with a wrench until the pry bar 4 and the washer 7 come into contact. Then, the push rod 1 is connected to the housing 2, so that the bottom of the push rod 1 contacts the top of the pry bar 4, causing the pry bar 4 to move downwards and insert into the washer 7, but without piercing it. The next step is as follows... Figure 7 As shown, pulling the pull plate 3 causes the pry bar 4 to pry the pad 7, creating a gap between the pad 7 and the connector 6, allowing the pad 7 to be removed. The pad 7 is then hooked out with a hook. The rubber block inside the support hole 21 serves as a buffer for the pry bar 4.
[0042] This utility model gasket removal device is used to remove gaskets from inside the connector nozzle or valve of a conduit. It can be replaced with a gasket removal tool of the same specification according to different gasket specifications.
[0043] The pry bar of this gasket removal device is positioned by the housing and the connecting nozzle. It applies a controllable peeling force to the gasket using the lever principle, avoiding direct violent prying that could scratch or deform the sealing surface of the connecting nozzle. The roller contacts the top rod to reduce friction, ensuring that the axial force applied by the top rod is stably transmitted to the pry bar, so that the gasket is subjected to uniform force and the risk of damage to the sealing surface is reduced.
[0044] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. The various components of this utility model can be combined with each other without conflict. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
