Description

Technical Field

[0001] The present invention relates to the technical field of electromechanical pipelines, and in particular to a sealing and protective structure for the connection of electromechanical pipelines in underground garages. Background Art

[0002] In the field of construction, with the increasing functionality of buildings, electromechanical pipelines are often used in the electromechanical field. The reserved and pre-buried wire pipes account for a very large proportion in the electromechanical field. Generally, through-wall openings are set on the masonry wall for the passage of electromechanical pipelines.

[0003] For example, a pipe connector with publication number CN214466896U is used to connect an inner pipe and an outer pipe, comprising an inner pipe, a pipe wall of the inner pipe having a notch along its axial direction, at least one end of the notch penetrating the pipe wall, the inner pipe being sleeved between the inner pipe and the outer pipe, the notch corresponding to the notch on the outer pipe; an outer sleeve, the outer sleeve being sleeved on the outside of the inner pipe, a receiving cavity being provided between the outer sleeve and the inner pipe, the outer pipe being clamped in the receiving cavity, and an opening being provided at a position corresponding to the notch on the outer sleeve; an adjustment assembly, the adjustment assembly being connected to the outer sleeve, the adjustment assembly being used to adjust the size of the opening, and the notch being closed or loosened by adjusting the opening. The pipe connector provided in this application is used to connect two inner and outer pipes, and the size of the notch on the pipe connector is adjusted by the adjustment assembly, thereby squeezing the outer pipe to shrink and compressing the inner pipe. The pipe connector has a simple structure, is easy to install, has good stability, can realize quick connection and fixation of the inner and outer pipes, and is suitable for pipes with greater hardness. However, this patent does not solve the problem of easy leakage in the current electromechanical pipeline connections. Due to the different components of the circulating medium, the electromechanical pipeline connectors will leak after a period of use, which will cause the connections to be damaged by the impact of pressure, resulting in increased replacement and maintenance costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a sealing and protective structure for the connection of electromechanical pipelines in underground garages, so as to solve the problem proposed in the above-mentioned background technology that the electromechanical pipeline connectors leak after a period of use, which in turn causes the connection to be damaged due to pressure impact, resulting in increased replacement and maintenance costs.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sealing and protective structure for the connection of electromechanical pipelines in an underground garage, comprising a first pipe and a second pipe arranged in the lower half of the first pipe, the first pipe portion being inserted into the second pipe, and the outer wall of the first pipe being in contact with the inner wall of the second pipe; further comprising: a fixing ring, the fixing ring being arranged on the outer circumferential surface of the first pipe, an annular groove being provided at the bottom of the fixing ring, a sealing layer being provided in the annular groove, and a sealing groove being provided at the bottom of the sealing layer; a connecting ring being provided at the top of the second pipe, the connecting ring being inserted into the sealing groove, and the connecting ring and the sealing layer being in an interference fit.

[0006] By adopting the above technical solution, through the cooperation of the fixing ring, the sealing groove, the sealing layer and the connecting ring, the connecting ring and the sealing layer are fully fitted together, so that the gap between the first pipe and the second pipe is completely blocked, thereby improving the sealing effect of the connecting piece between the first pipe and the second pipe, preventing the connecting part from being subjected to pressure shock, and reducing maintenance costs.

[0007] Preferably, sealing rings are provided on both the inner and outer walls of the second pipe, the sealing ring is arranged in an arc shape on the side away from the second pipe, and the sealing ring fits against the outer wall of the first pipe or the inner wall of the annular groove.

[0008] By adopting the above technical solution and setting the sealing ring, when the first pipe and the second pipe are matched, the sealing ring is deformed, further blocking the gap between the first pipe and the second pipe, thereby improving the sealing effect of the connecting piece between the first pipe and the second pipe.

[0009] Preferably, the connecting ring is configured such that the wall thickness gradually decreases from top to bottom.

[0010] By adopting the above technical solution, the wall thickness of the connecting ring is gradually reduced from top to bottom, so that the connecting ring is easily inserted into the sealing groove, and the sealing layer is squeezed toward both sides, so that the sealing layer is tightly attached to the connecting ring, thereby further improving the sealing effect of the first pipe and the second pipe connector.

[0011] Preferably, the outer circumferences of the first pipe and the second pipe are jointly provided with a connecting assembly, and the connecting assembly includes a plurality of fixing blocks, and the plurality of fixing blocks are evenly arranged on the lower half of the outer circumference of the first pipe. A placement groove is provided on the side of the fixing block away from the first pipe, and the top of the placement groove is provided with a through hole. A fixing rod is hingedly provided on the bottom wall of the placement groove, and the upper half of the fixing rod extends to the outside of the placement groove; a clamping assembly is provided below the fixing block.

[0012] By adopting the above technical solution, through the cooperation of the fixing block, the fixing rod and the clamping assembly, compared with the traditional flange connection, this structure makes it easier for operators to disassemble and install the connecting parts, thereby reducing the labor intensity of the operators.

[0013] Preferably, the clamping assembly includes a clamping ring, a clamping groove is provided on the top of the clamping ring, several of the fixing blocks are located in the clamping groove, a clamping groove is provided on the inner wall of the clamping groove, a clamping block is provided at a position corresponding to the clamping groove on the side of the fixing rod away from the first pipe, a spring is provided between the fixing rod and the fixing ring, and when the spring is in a natural state, the corresponding clamping block is inserted into the clamping groove.

[0014] By adopting the above technical solution, through the cooperation of the card slot, the card block and the spring, pressing the fixing rod can easily disengage the first pipe from the second pipe, making it convenient for the operator to disassemble and install the connecting piece, thereby reducing the labor intensity of the operator.

[0015] Preferably, the slot is annular.

[0016] By adopting the above technical solution, the annularly arranged card groove makes it unnecessary for the first pipe and the second pipe to be aligned at an angle during installation. It is only necessary to insert the first pipe into the second pipe, and the card block can be inserted into the card groove, thereby eliminating the step of aligning the card block with the card groove and facilitating use by the operator.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 5 The present invention provides a technical solution: a sealing and protective structure for the connection of electromechanical pipelines in an underground garage, comprising a first pipe 1 and a second pipe 2 arranged in the lower half of the first pipe 1, the first pipe 1 is partially inserted into the second pipe 2, and the outer wall of the first pipe 1 is in contact with the inner wall of the second pipe 2.

[0029] See Figure 1 The outer circumferences of the first and second pipes 1 and 2 are both provided with a connecting assembly 9. This connecting assembly 9 comprises a plurality of fixing blocks 91, evenly spaced along the lower half of the outer circumference of the first pipe 1. A placement slot 92 is defined on the side of the fixing blocks 91 facing away from the first pipe 1. The top of the placement slot 92 is provided with a through-hole. A fixing rod 93 is hingedly connected to the bottom wall of the placement slot 92, with the upper half of the fixing rod 93 extending outside the placement slot 92.

[0030] A snap-fit ​​assembly 94 is located below the fixed block 91. This assembly includes a snap ring 941 with a snap-fit ​​groove 942 defined at its top. Several fixed blocks 91 are positioned within these grooves, with the sidewalls of the fixed blocks 91 fitting snugly against the inner walls of these grooves, preventing the first pipe 1 from shaking horizontally. The inner wall of these grooves is also defined by a ring-shaped snap-fit ​​groove 943.

[0031] See Figure 2A locking block 944 is provided on the side of the fixing rod 93 away from the first pipe 1 at a position corresponding to the locking groove 943. A spring 945 is provided between the fixing rod 93 and the fixing ring 3. When the spring 945 is in a natural state, the corresponding locking block 944 is inserted into the locking groove 943. During the process of rotating the fixing rod 93 until the locking block 944 is out of the locking groove 943, the fixing rod 93 does not contact the inner wall of the placement groove 92.

[0032] When the clamping block 944 is inserted into the slot 943, the first pipe 1 and the second pipe 2 cannot move vertically relative to each other, and due to the high friction between the clamping block 944 and the slot 943, the first pipe 1 and the second pipe 2 cannot rotate relative to each other. The annular slot 943 eliminates the need for aligning the first and second pipes 1 and 2 during installation. Simply insert the first pipe 1 into the second pipe 2, and the clamping block 944 can be inserted into the slot 943 in any position.

[0033] When removing the first pipe 1 and the second pipe 2, press the fixing rod 93 to disengage the block 944 from the slot 943, lift the first pipe 1 upward or pull the second pipe 2 downward to separate the first pipe 1 and the second pipe 2, and then release the fixing rod 93. When installing the connector, first press the fixing rod 93, then insert the first pipe 1 into the second pipe 2, and then release the fixing rod 93. The block 944 automatically inserts into the slot 943, securing the first pipe 1 and the second pipe 2.

[0034] See Figure 2 The apparatus further includes a fixing ring 3 disposed on the outer circumference of the first pipe 1. An annular groove 4 is defined at the bottom of the fixing ring 3. A sealing layer 5 is disposed within the annular groove 4. The sealing layer 5 is made of a soft, deformable material. A sealing groove 6 is defined at the bottom of the sealing layer 5.

[0035] See Figure 1 and Figure 3 A connecting ring 7 is provided at the top of the second pipe 2 and is inserted into the sealing groove 6. The connecting ring 7 and the sealing layer 5 form an interference fit. The wall thickness of the connecting ring 7 gradually decreases from top to bottom, which not only facilitates the insertion of the connecting ring 7 into the sealing groove 6 but also squeezes the sealing layer 5 toward both sides, making it tightly attached to the connecting ring 7.

[0036] See Figure 1 and Figure 3 The second pipe 2 is provided with a sealing ring 8 on both the inner and outer walls. The side of the sealing ring 8 away from the second pipe 2 is arc-shaped and fits against the outer wall of the first pipe 1 or the inner wall of the annular groove 4. When the first pipe 1 is inserted into the second pipe 2, the sealing ring 8 deforms, further blocking the gap between the first and second pipes 1 and 2.

[0037] Working Principle: When removing the first pipe 1 and the second pipe 2, press the fixing rod 93 to disengage the block 944 from the slot 943, lift the first pipe 1 upward or pull the second pipe 2 downward to separate the first pipe 1 and the second pipe 2, and then release the fixing rod 93. When installing the connector, first press the fixing rod 93, then insert the first pipe 1 into the second pipe 2, and then release the fixing rod 93. The block 944 automatically inserts into the slot 943, securing the first pipe 1 and the second pipe 2.

[0038] When the first pipe 1 is inserted into the second pipe 2, the first pipe 1 squeezes the sealing ring 8, which is deformed to block the gap between the first pipe 1 and the second pipe 2. The connecting ring 7 is inserted into the sealing groove 6, squeezing the sealing layer 5, causing the sealing layer 5 to deform and thus tightly adhere to the connecting ring 7, further improving the sealing effect of the connection between the first pipe 1 and the second pipe 2.

[0039] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
