Description

Technical Field

[0001] This application relates to the field of splicing device technology, and in particular to a snap-on sealing mechanism for quick installation of splicing devices. Background Technology

[0002] Splicing devices are used, for example, on splicing towers to connect fiber optic composite ground wires. Traditional splicing devices seal by installing an O-ring between the cap and the base, then tightening the cap and base with six screws or other fasteners to compress the O-ring and achieve a seal. This sealing method requires tightening multiple screws and fasteners, making the operation cumbersome. To achieve a simpler and more convenient operation, existing splicing devices typically use snap-on sealing rings instead of traditional screws to secure the cap and base, thereby compressing the O-ring to achieve a seal.

[0003] However, the existing snap-on sealing rings are installed on the outside of the connecting device and require screws for fixing, which is still inconvenient in operation. In addition, the existing snap-on sealing rings do not have a good squeezing effect on the cap and the chassis, which may result in gaps in the connecting device after sealing installation, thus failing to ensure a good seal. Summary of the Invention

[0011] The locking assembly is used to connect the first extension block and the second extension block to lock the sealing ring body;

[0012] The outer peripheral surface of the sealing ring body is provided with a squeezing block that contacts and abuts against the pressure block in a one-to-one correspondence when the sealing ring body is in the locked state.

[0013] The pre-tightening assembly includes a pre-fixing rod and an elastic ball;

[0014] The first extension block has a first threaded hole on one side facing the second extension block;

[0015] The second extension block has a pre-threaded hole through itself on one side facing the first extension block;

[0016] One end of the pre-fixed rod can be movably inserted into the first threaded hole and threadedly connected to the first threaded hole;

[0017] The elastic ball can pass through the pre-second threaded hole and contact and abut against the other side of the second extension block opposite to the first extension block.

[0018] Furthermore, the top of the pressure block is provided with multiple evenly distributed grooves;

[0019] The bottom of the extrusion block is provided with multiple protrusions that correspond one-to-one with the grooves.

[0020] Furthermore, a connecting rod is provided protruding on the outer circumferential surface of the sealing ring body along the central axis direction of the sealing ring body;

[0021] The extrusion block is vertically connected to the top of the connecting rod.

[0022] Furthermore, the number of pressure blocks is two, and they are evenly distributed around the top of the fixed flange;

[0023] There are also two extrusion blocks, which correspond one-to-one with the pressure block.

[0024] Furthermore, the elastic ball is made of rubber material.

[0025] Furthermore, the locking assembly includes a screw;

[0026] Fixing posts are provided on the outer end faces of the first extension block and the second extension block away from the sealing ring body;

[0027] Both of the fixed posts have a second threaded hole that passes through them, allowing the screw to pass through and be threadedly connected to the screw;

[0028] The internal thread surfaces of the two second threaded holes rotate in opposite directions.

[0029] Furthermore, the locking assembly also includes a locking element;

[0030] A limiting groove is formed on the screw along its own axial direction;

[0031] The locking member is movably sleeved on the screw along the axial direction of the screw, and is provided with a limiting protrusion that engages with the limiting groove;

[0032] A locking hole is also provided on the other side of the second extension block opposite to the first extension block;

[0041] As can be seen from the above technical solution, the snap-on sealing mechanism for quick installation of the connecting device designed in this application involves placing the O-ring seal between the fixed flange and the fixed plate of the outer shell during installation and use, followed by fitting the sealing ring body of the snap-on seal. Then, the first extension block and the second extension block move closer to each other until the elastic ball on the pre-fixing rod passes through the pre-fixing hole of the second extension block. At this point, the contact between the elastic ball and the second extension block brings the first and second extension blocks into a close proximity, achieving a pre-tightening effect. Then, the locking assembly is used to lock the first and second extension blocks. The entire operation is simple and quick. Furthermore, when the sealing ring body is locked, the contact between the extrusion block and the pressure block further provides extrusion force to the fixed flange, thereby better compressing the fixed flange and the fixed plate. This allows the O-ring seal located between the fixed flange and the fixed plate to provide a better seal, preventing gaps in the connecting device after installation and achieving a better sealing effect.

[0053] This application discloses a snap-on sealing mechanism for quick installation of a splicing device.

[0054] Please see Figure 1 as well as Figure 4 One embodiment of a snap-on sealing mechanism for quick installation of a connecting device provided in this application includes:

[0055] It includes a hollow outer shell 1, a snap-on sealing ring, and a fixing plate 4.

[0056] The bottom of the outer casing 1 is provided with a fixing flange 2, and the top of the fixing flange 2 is provided with a pressure block 7.

[0057] The snap-on sealing ring includes the sealing ring body 3, the locking component, and the pre-tightening component.

[0058] The sealing ring body 3 is sleeved on the outer edge of the fixing flange 2 and the fixing plate 4. At both ends of the outer circumferential surface of the sealing ring body 3, there are a first extension block 11 and a second extension block 15 extending in the radial direction of the sealing ring body 3.

[0059] The locking assembly is used to connect the first extension block 11 and the second extension block 15 to lock the sealing ring body 3.

[0060] The outer circumferential surface of the sealing ring body 3 is provided with a pressing block 9 that corresponds to and abuts against the pressure block 7 when the sealing ring body 3 is in the locked state.

[0061] The pre-tightening assembly includes a pre-fixing rod 13 and an elastic ball 14. The first extension block 11 has a first threaded hole 12 on the side facing the second extension block 15. The second extension block 15 has a pre-second threaded hole 25 that passes through itself on the side facing the first extension block 11. One end of the pre-fixing rod 13 can be movably inserted into the first threaded hole 12 and threadedly connected to the first threaded hole 12. The elastic ball 14 can pass through the pre-second threaded hole 25 and contact and abut against the other side of the second extension block 15 away from the first extension block 11.

[0062] As can be seen from the above technical solution, the snap-on sealing mechanism for quick installation of the connecting device designed in this application, when installed and used, involves placing the O-ring between the fixing flange 2 and the fixing plate 4 of the outer shell 1, and then fitting the sealing ring body 3 of the snap-on sealing ring. Then, the first extension block 11 and the second extension block 15 move closer to each other until the elastic ball 14 on the pre-fixing rod 13 passes through the pre-fixing hole 16 of the second extension block 15. At this time, the contact between the elastic ball 14 and the second extension block 15 can be used to make the first extension block 11 and the second extension block 15 close together, thus achieving the pre-tightening effect. Then, the locking assembly is used to lock the first extension block 11 and the second extension block 15. The whole operation process is simple and quick. Furthermore, when the sealing ring body 3 is locked, the contact and mutual engagement between the extrusion block 9 and the pressure block 7 can further provide the extrusion force of the fixed flange 2, thereby better compressing the fixed flange 2 and the fixed plate 4, so that the O-ring seal located between the fixed flange 2 and the fixed plate 4 can play a better sealing role, avoiding the possibility of gaps in the joint device after sealing installation, and achieving a better sealing effect.

[0063] The above is Embodiment 1 of a snap-on sealing mechanism for quick installation of a connecting device provided in this application. The following is Embodiment 2 of a snap-on sealing mechanism for quick installation of a connecting device provided in this application. Please refer to the following for details. Figures 1 to 6 .

[0064] Based on the solution of Embodiment 1 above:

[0065] Furthermore, the top of the pressure block 7 has multiple evenly distributed grooves 8, and the bottom of the extrusion block 9 has multiple protrusions 22 that correspond one-to-one with the grooves 8. When the locking assembly locks the sealing ring body 3, the extrusion block 9 moves against the sealing ring body 33. It can be understood that during the locking process, the opening of the sealing ring body 3 will gradually narrow. During the narrowing process, the sealing ring body 3 itself will also undergo a certain deformation, which will cause the extrusion block 9 to move relative to it. When the sealing ring body 3 is locked, the extrusion block 9 moves to the top of the pressure block 7 and comes into contact with the pressure block 7, thereby achieving better extrusion between the fixed flange 2 and the fixed plate 4. The design of the protrusions 22 can cooperate with the grooves 8, thereby making the contact between the extrusion block 9 and the pressure block 7 more stable and reliable.

[0066] To allow the extrusion block 9 to move more smoothly to the top of the pressure block 7, the edges of the upper surface of the pressure block 7 are rounded and chamfered. Similarly, the edges of the lower surface of the extrusion block 9 are also rounded and chamfered. In addition, the distance between the extrusion block 9 and the fixed flange 2 is less than the thickness of the pressure block 7, ensuring that the extrusion block 9 can exert a certain extrusion force on the pressure block 7 after contacting it.

[0067] Furthermore, a connecting rod 10 is protruding on the outer circumferential surface of the sealing ring body 3 along the central axis direction of the sealing ring body 3, and the extrusion block 9 is vertically connected to the top of the connecting rod 10.

[0068] Furthermore, in this application, the number of pressure blocks 7 is preferably designed to be two, which are evenly arranged on the top of the fixed flange 2. Correspondingly, the number of extrusion blocks 9 is also two, corresponding one-to-one with the pressure blocks 7.

[0069] Furthermore, the elastic ball 14 is made of rubber material, or of course, other materials with certain elastic properties. When a certain force is applied, the elastic ball 14 can be squeezed through the pre-fixing hole 16. When no additional force is applied, the elastic ball 14 can contact and abut against the second extension block 15 to restrict the first extension block 11 and the second extension block 15 to a relatively close position to achieve pre-fixation.

[0070] Furthermore, the locking assembly includes a screw 21.

[0071] Both the first extension block 11 and the second extension block 15 have fixing posts 24 on their outer end faces away from the sealing ring body 3. Each fixing post 24 has a second threaded hole 25 that passes through itself, allowing the screw 21 to pass through and be threadedly connected to the screw 21. The internal thread surfaces of the two second threaded holes 25 have opposite directions of rotation. With this design, by rotating the screw 21, the first extension block 11 and the second extension block 15 can be moved closer to each other or further away from each other, so as to achieve a locking connection between the first extension block 11 and the second extension block 15.

[0072] Furthermore, the locking assembly also includes a locking member 17. A limiting groove 20 is formed on the screw 21 along its own axial direction. The locking member 17 is movably sleeved on the screw 21 along the axial direction of the screw 21 and is provided with a limiting protrusion 172 that is engaged with the limiting groove 20. A locking hole 19 is also formed on the other side of the second extension block 15 opposite to the first extension block 11. A fixing rod 18 is provided on the locking member 17 that is movably inserted into the locking hole 19.

[0073] By utilizing the engagement between the limiting protrusion 172 and the limiting groove 20, the locking member 17 can be movably engaged with the screw 21 along the axial direction, but fixedly engaged with the screw 21 in the circumferential direction. After the screw 21 completes the locking connection between the first extension block 11 and the second extension block 15, the locking member 17 can be fitted onto the end section of the screw 21 that passes through the second extension block 15, and the fixing rod 18 on the locking member 17 can be inserted into the locking hole 19, thereby locking the rotation of the screw 21, preventing accidental operation of the screw 21, ensuring a stable and reliable locking state between the first extension block 11 and the second extension block 15, and preventing the screw 21 from loosening.

[0074] Furthermore, the outer surface of the fixing rod 18 is covered with a rubber pad that can contact the inner wall of the locking hole 19. The design of the rubber pad can increase the contact friction between the fixing rod 18 and the locking hole 19, making the fit between the fixing rod 18 and the locking hole 19 more stable and reliable.

[0075] Furthermore, the locking member 17 has a first tooth 171 on its outer peripheral surface, and the second extension block 15 has a third extension block 23 on its outer end face away from the sealing ring body 3. The third extension block 23 has a second tooth 231 that meshes with the first tooth. By utilizing the meshing of the first and second teeth, the rotation of the locking member 17 can be further restricted, thereby further restricting the rotation of the screw 21 and better ensuring the locking effect of the screw 21. Specifically, the locking member 17 can also be designed using gears, without limitation.

[0076] Furthermore, the fixing plate 4 is located at the bottom of the outer casing 1, and its upper surface has multiple through holes 5;

[0077] The bottom of the fixing plate 4 is provided with multiple insertion tubes 6. The inside of the insertion tubes 6 is hollow and they are connected to each other one by one. The through holes 5 and insertion tubes 6 are used to insert fiber optic composite ground wires. The end of the inserted fiber optic composite ground wire is connected to the inside of the outer shell 1.

[0078] The above provides a detailed description of a snap-on sealing mechanism for quick installation of a connecting device provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
