Description

Technical Field

[0001] This utility model relates to the field of pipe sealing technology, and in particular to a sealing device for a ribbed bend pipe. Background Technology

[0002] In existing pipe bending connection technologies, the internal insertion method is commonly used. A sealing strip is wrapped around the smaller end of the pipe fitting, and then this smaller end is inserted into the larger end of another pipe fitting to seal the connection. However, the presence of the sealing strip makes insertion difficult. The sealing strip has elasticity and friction, requiring the fitting to overcome significant resistance during insertion. This not only increases installation difficulty and time costs but also may cause the sealing strip to shift or twist during installation, affecting the sealing effect. Furthermore, the sealing strip is prone to aging and wear, reducing sealing performance and even causing leaks, posing a threat to the normal operation and safety of related equipment.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a ribbed bend sealing device. The ribbed bend sealing device includes a main component 100, a bend 101 and a connecting pipe 102, with the connecting pipe 102 located on one side of the bend 101.

[0030] A sealing assembly 200 is disposed at one end of the bend 101 and includes a mounting component 201. The mounting component 201 includes a first connector 201a, a second connector 201b, and a locking block 201c. The first connector 201a is fixed to one end of the bend 101, the second connector 201b is fixed to one end of the connecting pipe 102, and the locking block 201c is fixed to the second connector 201b. A locking groove 201a-1 is provided on the first connector 201a, and the locking block 201c can engage with the locking groove 201a-1.

[0031] The mounting component 201 is designed to securely connect and fix the bend 101 and the connecting pipe 102. The locking block 201c is annular. Through the cooperation of the locking block 201c and the locking groove 201a-1, when the locking block 201c is fully engaged with the locking groove 201a-1, the bend 101 and the connecting pipe 102 are connected.

[0032] The sealing assembly 200 also includes a sealing ring 202. One end of the sealing ring 202 is fitted with the end face of the first connector 201a. A through groove 202-1 corresponding to the locking block 201c is opened on the sealing ring 202. The locking block 201c is inserted into the through groove 202-1. The other end of the sealing ring 202 is fitted with the end face of the second connector 201b.

[0033] The sealing ring 202 is used to ensure the sealing of the connection between the bend 101 and the connecting pipe 102. When the bend 101 and the connecting pipe 102 are connected, force is applied to make them fit more tightly. The first joint 201a and the second joint 201b will simultaneously apply compressive force to the sealing ring 202, thereby causing the sealing ring 202 to deform. This brings the first joint 201a and the second joint 201b closer together, thereby enhancing the sealing of the connection between the bend 101 and the connecting pipe 102.

[0034] Example 2

[0035] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the sealing assembly 200 also includes a locking element 203, which is disposed on one side of the locking block 201c. It includes a locking block 203a and a first spring 203b. A first moving groove 201a-2 is provided in the first connector 201a. The locking block 203a slides in the first moving groove 201a-2. The first spring 203b is fixed to one end of the locking block 203a and the other end is fixed to the inner wall of the first moving groove 201a-2. A locking groove 201c-1 is provided on the locking block 201c. The locking block 203a can engage with the locking groove 201c-1.

[0037] The locking element 203 is used to lock the position of the locking block 201c, ensuring that after the locking block 201c moves to the appropriate position, it will not move again, which would cause the connection between the bend pipe 101 and the connecting pipe 102 to be unstable and affect subsequent use.

[0038] The first spring 203b applies a continuous thrust to the locking block 203a to ensure that the locking block 203a can engage with the locking groove 201c-1. Through the cooperation between the locking block 203a and the locking groove 201c-1, when the two are engaged, the movement of the locking block 201c in the groove 201a-1 will be restricted, preventing the locking block 201c from shifting position and affecting the sealing effect of the sealing ring 202.

[0039] Specifically, a second moving groove 201a-3 is provided in the first connector 201a, and a moving block 203c is provided in the second moving groove 201a-3. A second spring 203d is fixed to one end of the moving block 203c, and the other end of the second spring 203d is fixed to the inner wall of the second moving groove 201a-3.

[0040] The movable block 203c is used to unlock the engagement between the locking block 203a and the locking groove 201c-1. When it is necessary to unlock the limit of the locking block 201c, the movable block 203c moves along the second movable groove 201a-3 towards the direction of the locking block 203a. At this time, the second spring 203d will extend.

[0041] Specifically, a force-receiving groove 203a-1 is provided on the locking block 203a, and one end of the moving block 203c can engage with the force-receiving groove 203a-1.

[0042] As the moving block 203c moves, one end of the moving block 203c will contact and press against the force groove 203a-1, thereby causing the locking block 203a to move upward along the first moving groove 201a-2, moving the locking block 203a away from the locking groove 201c-1, and thus separating the two. At this time, the card block 201c can move arbitrarily within the card groove 201a-1 again.

[0043] Specifically, one end of the movable block 203c is inclined, and the shape of the force-receiving groove 203a-1 corresponds to it.

[0044] By tilting the movable block 203c, when it moves, its tilted surface will first contact the inclined surface of the force groove 203a-1 and squeeze it, thereby separating the locking block 203a from the locking groove 201c-1. At this time, the locking block 203a will not affect the movement of the locking block 201c.

[0045] Specifically, one end of the locking block 203a is inclined, and there are multiple locking grooves 201c-1. The locking grooves 201c-1 are circular in shape and have inclined slopes.

[0046] The locking block 201c is circular in shape, and the locking groove 201c-1 is set on the arc surface of the locking block 201c in a ring shape, so as to ensure that the bend 101 and the connecting pipe 102 are connected at any angle, and the locking block 203a can engage with the locking groove 201c-1, thereby limiting the locking block 201c.

[0047] The inclined surface of locking block 203a can contact and press against the inclined surface of locking groove 201c-1. When pushing the card block 201c to engage with the card groove 201a-1, the inclined surface of locking block 203a will first contact the end face of card block 201c, and card block 201c will press against the inclined surface of locking block 203a, thereby moving locking block 203a away from card block 201c and not hindering card block 201c from engaging with card groove 201a-1.

[0048] By setting multiple locking grooves 201c-1, when the bend 101 and the connecting pipe 102 are initially connected, the locking block 203a can engage with one of the locking grooves 201c-1. When the bend 101 and the connecting pipe 102 are pushed to make them more tightly connected, the first connector 201a and the second connector 201b simultaneously squeeze the sealing ring 202, causing it to deform. At this time, the inclined surface of the locking block 203a will squeeze the inclined surface of the locking groove 201c-1, thereby causing the locking block 203a to move upward. The first spring 203b will be compressed, and the locking block 203a will not affect the movement of the locking block 201c in the locking groove 201a-1. When the locking block 203a is once again in a coaxial position with another locking groove 201c-1, the first spring 203b returns to its original position, causing the locking block 203a to engage with the locking groove 201c-1 again, thereby restricting the movement of the locking block 201c again and improving the sealing effect of the sealing ring 202.

[0049] Example 3

[0050] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, the sealing ring 202 is made of rubber and has a certain deformation capacity.

[0052] When force is applied to bring the bend 101 and the connecting pipe 102 closer together, the first connector 201a and the second connector 201b simultaneously squeeze the sealing ring 202, causing the sealing ring 202 to deform, thereby bringing the bend 101 and the connecting pipe 102 closer together.

[0053] Specifically, a rubber block 201d is fixed to the inner wall of the slot 201a-1, and the card block 201c can fit with the rubber block 201d.

[0054] When the bend 101 and the connecting pipe 102 are initially connected, as a pushing force is applied, the clamping block 201c and the rubber block 201d deform together. At the same time, the end face of the clamping block 201c will also squeeze the rubber block 201d, causing the rubber block 201d to deform synchronously.

[0055] Specifically, there are four sets of locking blocks 203a and first springs 203b, which are evenly distributed within the first connector 201a.

[0056] By simultaneously limiting the locking block 201c by the four locking blocks 203a, it is ensured that the locking block 201c will not move again after moving to the appropriate position, which would prevent the sealing ring 202 from tightly fitting with the first connector 201a and the second connector 201b, thus affecting the sealing effect.

[0057] Specifically, a connecting plate 203e is fixed to one end of the movable block 203c, and a compression ring 203f is fixed to one side of the connecting plate 203e.

[0058] The connecting plate 203e is used to unlock the locking block 203a from the locking groove 201c-1. Pushing the connecting plate 203e causes the moving block 203c to move along the second moving groove 201a-3 towards the locking block 203a. The second spring 203d will be stretched, causing the moving block 203c to move closer to the force groove 203a-1. The inclined surface of the moving block 203c presses against the inclined surface of the force groove 203a-1, causing the locking block 203a to move upward along the first moving groove 201a-2, thereby separating the locking block 203a from the locking groove 201c-1. At this time, pulling the connecting tube 102 will cause the second connector 201b to move away from the first connector 201a, separating the first connector 201a from the groove 201a-1, thereby disconnecting the bend tube 101 from the connecting tube 102.

[0059] Pushing the compression ring 203f to move the connecting plate 203e will cause the four locking blocks 203a to separate from the locking groove 201c-1 at the same time, thereby unlocking the limit on the card block 201c, so that the card block 201c can be smoothly separated from the card groove 201a-1.

[0060] After the connecting plate 203e stops being pushed, the second spring 203d returns to its original position, which will push the second spring 203d to move away from the moving block 203c and back to its initial position, while the compression ring 203f returns to its initial position.

[0061] In use, the sealing ring 202 is installed onto one end of the second connector 201b, and the locking block 201c is inserted into the through groove 202-1. Then, the second connector 201b is moved, causing the locking block 201c to engage with the locking groove 201a-1. As the locking block 201c moves, when one of the locking grooves 201c-1 is coaxial with the locking block 203a, the two engage, initially connecting the bend 101 and the connecting pipe 102. Then, when the bend 101 and the connecting pipe 102 are pushed forcefully to make the connection tighter, the first connector 201a and the second connector 201b simultaneously compress the sealing ring 202, causing it to deform. When the distance between the first connector 201a and the second connector 201b decreases, the inclined surface of the locking block 203a will press against the inclined surface of the locking groove 201c-1, thereby causing the locking block 203a to move upward. The first spring 203b will be compressed, and the locking block 203a will not affect the movement of the locking block 201c in the groove 201a-1. When the locking block 203a is once again in a coaxial position with the other locking groove 201c-1, the first spring 203b will return to its original position, causing the locking block 203a to engage with the locking groove 201c-1 again, thereby restricting the movement of the locking block 201c again and improving the sealing effect of the sealing ring 202.

[0062] When the sealing effect is slightly reduced, the bend 101 and the connecting pipe 102 can be pushed harder again to make them more tightly connected, and the sealing ring 202 will be squeezed again, thereby temporarily improving the sealing performance.

[0063] When the sealing ring 202 needs to be replaced, push the compression ring 203f to move the connecting plate 203e, and move the moving block 203c along the second moving groove 201a-3 towards the locking block 203a. The second spring 203d will be extended, so that the moving block 203c is close to the force groove 203a-1. The inclined surface of the moving block 203c presses against the inclined surface of the force groove 203a-1, so that the locking block 203a moves upward along the first moving groove 201a-2, and then the locking block 203a separates from the locking groove 201c-1. At this time, pull the connecting pipe 102, which will move the second connector 201b away from the first connector 201a, so that the first connector 201a separates from the slot 201a-1, thereby disconnecting the bend pipe 101 from the connecting pipe 102, and the sealing ring 202 can be replaced.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
