Description

Technical Field

[0001] This utility model relates to the technical field of protective caps, specifically a new type of rust-proof cap. Background Technology

[0002] End upsetting heads have multiple functions. For example, in automotive bolts, rivets, and other connecting parts, end upsetting heads can provide a larger bearing area, ensuring the reliability and stability of the connection and preventing the connecting parts from loosening or falling off during use. At the ends of some shaft parts, upsetting heads can be used to install positioning devices or cooperate with other components to play a role in precise positioning and force transmission. Existing end upsetting head protective caps only have dustproof functions and do not have rustproof functions. They do not have a vacuum chamber and are easily rusted by water in the air, affecting the surface morphology and appearance quality of the upsetting head, which has a negative impact on the assembly of the vehicle at the OEM. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a novel anti-rust cap. It effectively solves the problem of rust formation on the brake pipe end upsetting head when exposed to moisture in the air through both anti-rust oil and a sealed cavity. This addresses the issue that existing end upsetting head protective caps only provide dust protection and lack rust prevention. They also lack a vacuum cavity, making them highly susceptible to rusting due to moisture in the air, affecting the surface morphology and appearance of the upsetting head, and negatively impacting vehicle assembly at the OEM.

[0007] Preferably, a movable tube is movably sleeved on the protective cap, an annular groove is formed on the inner side wall of the movable tube, a sealing ring is fixedly installed on the inner side wall of the annular groove, the sealing ring is in contact with the outer side wall of the protective cap, and a baffle is fixedly installed on the right end of the movable tube, with an air groove formed on the baffle.

[0008] Preferably, a short pipe b is fixedly installed inside the air groove, a blocking ring b is fixedly installed inside the short pipe b, a short rod b is movably connected inside the blocking ring b, a circular plate b is fixedly installed on the left side of the short rod b, a pressure spring b is fixedly installed on the right side of the circular plate b, the left and right ends of the pressure spring b are fixedly connected to the circular plate b and the blocking ring b respectively, a sealing plate b is fixedly installed on the right end of the short rod b, the sealing plate b is in contact with the right side of the short pipe b, and two arc-shaped plates b are attached to the circular plate b, both of which are fixedly connected to the blocking ring b.

[0009] Preferably, a shielding tube is movably sleeved on the short tube b, the shielding tube is fixedly connected to the baffle, and a filter plate is fixedly installed inside the shielding tube.

[0010] Preferably, a metal ring is fixedly installed on the left side of the movable tube, a fixing ring is fixedly installed on the protective cap, and several magnets are embedded on the right side of the fixing ring, with a flexible plate fixedly installed on the right side of each magnet.

[0011] Preferably, a rotating ring is movably sleeved on the protective cap, and several movable columns are fixedly installed on the rotating ring. Several limiting rods are fixedly installed on the left side of the rotating ring, and a small ring is fixedly sleeved on each limiting rod. An annular block is movably sleeved on the several limiting rods. The annular block is fixedly connected to the protective cap. A circular ring is fixedly sleeved on the connecting head. Several circular grooves are opened on the circular ring. Each limiting rod is movably connected to each circular ring.

[0012] Compared with the prior art, this utility model provides a novel rust-proof cap, which has the following beneficial effects:

[0013] 1. This new type of rust-proof cap is made by placing rust-proof adsorption material at the bottom of the sealing cavity of the protective cap to form a rust-proof adsorption sealing plug. Then, the brake pipe end upsetting head and connector are installed into the protective cap in sequence. In this way, the rust-proof oil and the sealing cavity can effectively solve the problem of the brake pipe end upsetting head rusting when exposed to moisture in the air.

[0014] 2. This new type of rust-proof cap can expel internal air through the exhaust pipe when installing the protective cap, thus avoiding the situation where the protective cap cannot be installed due to the inability to expel internal air.

[0015] 3. This new type of rust-proof cap can seal the short pipe a through the sealing plate a. When the protective cap is installed, the internal air is discharged through the exhaust pipe. The discharged air will push the sealing plate a to move to the right and then discharge the air. After the air is discharged, the rebound of the pressure spring a will drive the sealing plate a to fit with the blocking ring a to perform a sealing treatment to prevent external moisture and other substances from entering the protective cap.

[0016] 4. This new type of rust-proof cap works by first moving the moving tube to the left, then blocking the air groove and then moving the moving tube to the right. This creates a negative pressure inside the moving tube, which in turn moves the sealing plate a to the right, drawing out the air from inside the sealing cap. This allows the sealing ring to fit more closely with the sealing head for a seal.

[0017] 5. This new type of rust-proof cap uses two left-moving tubes to compress the internal air, which in turn causes the sealing plate b to move to the right, expelling the air from the tubes. When the tubes move to the right again, the rebound of the pressure spring b causes the sealing plate a to seal the short tube b, thus creating negative pressure to draw out the air from the protective cap.

[0018] 6. This new type of rust-proof cap can protect the sealing plate and other mechanisms from scratches by external objects through the shielding tube and filter plate. The magnet can attract the metal ring when it gets close. Although it is relatively difficult to move the moving tube to the right due to the attraction force, it can effectively fix the moving tube and prevent it from shaking back and forth for effective use.

[0019] 7. This new type of rust-proof cap can be rotated back and forth by moving the rotating ring to the right, and the protective cap can be rotated back and forth by the movable column after the protective cap is installed. The rotating ring can be moved to the left to drive the limit rod to move to the left and insert it into the corresponding circular groove, thereby preventing the rotating cap from rotating off.

[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] Example 1, please refer to Figures 1-2This utility model provides a technical solution: a novel anti-rust cap, including an end head 1, a sealing head 14 at the right end of the end head 1, a connector 2 sleeved on the end head 1, a threaded groove 27 on the connector 2, a protective cap 6 threadedly sleeved on the threaded groove 27, a sealing cavity 28 inside the protective cap 6, an anti-rust adsorption sealing plug 15 installed inside the sealing cavity 28, the sealing head 14 being placed inside the sealing cavity 28, the sealing head 14 fitting snugly with the anti-rust adsorption sealing plug 15, the anti-rust adsorption sealing plug 15 being made of anti-rust adsorption material, by placing anti-rust adsorption material at the bottom of the sealing cavity 28 of the protective cap 6 to make the anti-rust adsorption sealing plug 15, and then sequentially installing the brake pipe end head 1 and connector 2 into the protective cap 6, thus effectively solving the problem of rust formation when the brake pipe end head 1 encounters moisture in the air through the two methods of anti-rust oil and sealing cavity 28;

[0031] Example 2, please refer to Figures 3-7Based on Embodiment 1, an exhaust pipe 16 is fixedly inserted through the rust-proof adsorption sealing plug 15, and the exhaust pipe 16 is fixedly inserted through the protective cap 6. A sealing ring 41 is fixedly installed inside the protective cap 6, and the sealing ring 41 is fitted against the left side of the sealing head 14. The exhaust pipe 16 can expel the internal air when installing the protective cap 6, thereby avoiding the situation where the protective cap 6 cannot be installed due to the inability to expel the internal air. A short pipe a20 is fixedly installed on the right side of the protective cap 6, and a blocking ring a33 is fixedly installed inside the short pipe a20. A short rod a32 is movably connected inside the blocking ring a33. A circular plate a34 is fixedly installed on the left side of the short rod a32, and a pressure spring a30 is fixedly installed on the right side of the circular plate a34. The left and right ends of the pressure spring a30 are respectively connected to the circular plate a34 and the blocking ring a34. 3. Fixed connection: A sealing plate a31 is fixedly installed on the right end of the short rod a32. The sealing plate a31 is in contact with the right side of the short pipe a20. Two arc-shaped plates a29 are attached to the round plate a34. Both arc-shaped plates a29 are fixedly connected to the blocking ring a33. The sealing plate a31 can seal the short pipe a20. When the protective cap 6 is installed, the internal air is discharged through the exhaust pipe 16. The discharged air will push the sealing plate a31 to move to the right and then discharge the air. After the air is discharged, the rebound of the pressure spring a30 will drive the sealing plate a31 to fit with the blocking ring a33 to seal and prevent external moisture from entering the protective cap 6. A movable pipe 4 is movably sleeved on the protective cap 6. The inner wall of the movable pipe 4 has an annular groove 21. A sealing ring 22 is fixedly installed on the inner wall of the protective cap 6. The sealing ring 22 fits against the outer wall of the protective cap 6. A baffle 5 is fixedly installed on the right end of the moving tube 4. An air groove 17 is opened on the baffle 5. By first moving the moving tube 4 to the left, then blocking the air groove 17, and then moving the moving tube 4 to the right, a negative pressure will be generated in the moving tube 4, thereby driving the sealing plate a31 to move to the right and sucking out the air in the sealing cap 6. This allows the sealing ring 41 to fit further against the sealing head 14 for sealing. A short tube b42 is fixedly installed in the air groove 17. A blocking ring b39 is fixedly installed in the short tube b42. A short rod b38 is movably connected in the blocking ring b39. A circular plate b40 is fixedly installed on the left side of the short rod b38. A pressure spring is fixedly installed on the right side of the circular plate b40. The pressure spring b36 is fixedly connected to the circular plate b40 and the blocking ring b39 at its left and right ends, respectively. A sealing plate b37 is fixedly installed on the right end of the short rod b38, and the sealing plate b37 is attached to the right side of the short tube b42. Two arc-shaped plates b35 are attached to the circular plate b40, and both arc-shaped plates b35 are fixedly connected to the blocking ring b39. When the internal air is compressed by the two left-moving moving tubes 4, the sealing plate b37 will move to the right, and then the air in the moving tube 4 will be discharged. When the moving tube 4 moves to the right again, the rebound of the pressure spring b36 will cause the sealing plate a31 to seal the short tube b42, thus generating a negative pressure to draw out the air in the protective cap 6. A baffle tube 19 is movably sleeved on the short tube b42, and the baffle tube 19 is fixedly connected to the baffle 5.A filter plate 18 is fixedly installed inside the shielding tube 19. A metal ring 7 is fixedly installed on the left side of the moving tube 4. A fixing ring 25 is fixedly installed on the protective cap 6. Several magnets 24 are embedded on the right side of the fixing ring 25. A flexible plate 23 is fixedly installed on the right side of each magnet 24. The shielding tube 19 and the filter plate 18 can protect the sealing plate b37 and other mechanisms from scratches by external objects. The magnets 24 can attract the metal ring 7 when it comes close. Although it is relatively difficult to move the moving tube 4 to the right due to the attraction force, it can effectively fix the moving tube 4 and prevent it from shaking back and forth for effective use. A rotating ring 8 is movably sleeved on the protective cap 6. Several movable On the left side of the column 9 and rotating ring 8, several limiting rods 10 are fixedly installed. Each limiting rod 10 has a small ring 11 fixedly fitted onto it. Annular blocks 26 are movably fitted onto the limiting rods 10, and the annular blocks 26 are fixedly connected to the protective cap 6. A circular ring 12 is fixedly fitted onto the connector 2. Several circular grooves 13 are formed on the circular ring 12. Each limiting rod 10 is movably connected to each circular ring 12. By moving the rotating ring 8 to the right, the protective cap 6 can be rotated back and forth via the movable column 9. After the protective cap 6 is rotated and installed, the rotating ring 8 can be moved to the left, causing the limiting rods 10 to move to the left and insert into the corresponding circular grooves 13, thus preventing the rotating cap 6 from rotating and falling off.

[0032] When using it, the first step is to put rust-proof absorbent material into the bottom of the sealing cavity 28 of the protective cap 6 to make a rust-proof absorbent sealing plug 15, and then install the brake pipe end upsetting head 1 and connector 2 into the protective cap 6 in sequence. In this way, the rust-proof oil and the sealing cavity 28 can effectively solve the problem of the brake pipe end upsetting head 1 rusting when it encounters moisture in the air.

[0033] Step 2: The exhaust pipe 16 can expel the internal air when installing the protective cap 6, thus avoiding the situation where the protective cap 6 cannot be installed due to the inability to expel the internal air.

[0034] Step 3: The sealing plate a31 can seal the short pipe a20. When the protective cap 6 is installed, the internal air is discharged through the exhaust pipe 16. The discharged air will push the sealing plate a31 to the right and then discharge the air. After the air is discharged, the rebound of the pressure spring a30 will cause the sealing plate a31 to fit with the blocking ring a33 to seal and prevent external moisture from entering the protective cap 6.

[0035] Step 4: By first moving the moving tube 4 to the left, then blocking the air groove 17 and then moving the moving tube 4 to the right, a negative pressure will be generated inside the moving tube 4, which will drive the sealing plate a31 to move to the right and then draw out the air from the sealing cap 6. This will allow the sealing ring 41 to further fit with the sealing head 14 for sealing.

[0036] Step 5: By moving the two left-hand moving tubes 4, the internal air is compressed, which will drive the sealing plate b37 to move to the right and then expel the air in the moving tubes 4. When the moving tubes 4 move to the right again, the rebound of the pressure spring b36 will drive the sealing plate a31 to seal the short tube b42, thus generating negative pressure to draw out the air in the protective cap 6.

[0037] Step 6: The shielding tube 19 and the filter plate 18 can protect the sealing plate b37 and other mechanisms from scratches by external objects. The magnet 24 can attract the metal ring 7 when it gets close. Although it is more difficult to move the moving tube 4 to the right due to the attraction force, it can effectively fix the moving tube 4 to prevent it from shaking back and forth and make it effective for use.

[0038] Step 7: By moving the rotating ring 8 to the right, the protective cap 6 can be rotated back and forth by the movable column 9. After the protective cap 6 is rotated and installed, the rotating ring 8 can be moved to the left to drive the limit rod 10 to move to the left and insert it into the corresponding circular groove 13, thereby preventing the rotating cap 6 from rotating and falling off.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
