Abstract
Description
Technical Field
[0001] The utility model relates to the field of conductive pipe connection structures, in particular to a conductive pipe sealing connection structure. Background Art
[0002] Conductive tubes are divided into two categories: metal and non-metal. Conductive tubes are usually nested on the outside of wires, playing an auxiliary role in the transportation of electrical energy by wires, reducing the loss of electrical energy transported by wires in the circuit, thereby achieving efficient transportation of electrical energy.
[0003] When existing conductive tubes need to be connected to each other, the two conductive tubes are generally connected to each other by tightening the protruding external thread column and the recessed internal thread column between the two conductive tubes.
[0004] With respect to the above-mentioned related technologies, after the existing conductive tubes are connected to each other, there are certain gaps between the threads, and water in the external environment can easily penetrate into the conductive tubes along the gaps between the threads. In summary, the existing conductive tube connection structure has the problem of poor sealing. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a conductive tube sealing pipe connection structure to solve the technical problem of poor sealing performance of the existing conductive tube connection structure.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a conductive tube sealing pipe connection structure, comprising a first tube body and a second tube body, wherein the ends of the first tube body and the second tube body close to each other are both provided with an annular clamping platform, one end of the first tube body is fixedly connected with a frustum, and an external threaded column is connected along the frustum, the inner wall of one end of the second tube body is provided with a conical groove that fits the frustum, and an internal threaded column that cooperates with the external threaded column is provided along the conical groove, and a hollow ring is clamped on the clamping platform between the first tube body and the second tube body.
[0007] By adopting the above technical solution, the two conductive tubes are threadedly connected and the mutual extrusion between the conical boss and the groove is used to achieve a sealing and waterproof effect. The extrusion generated when the two conductive tubes are connected to each other is used to deform the hollow ring. The deformed hollow ring squeezes the gap between the two conductive tubes, thereby further improving the sealing performance of the conductive tube connection.
[0008] The utility model is further configured such that both ends of the outer wall of the hollow ring are fixedly connected with a plurality of mutually corresponding fixing plates, a mounting ear is connected between two mutually corresponding fixing plates, and the length direction of the mounting ear is consistent with the diameter direction of the hollow ring.
[0009] By adopting the above technical solution, the spliced conductive tubes can be conveniently installed on the required installation surface by utilizing the installation ears connected to the fixing plate.
[0010] The utility model is further configured that a notch is provided at a position of the mounting ear close to the hollow ring.
[0011] By adopting the above technical solution, the mounting ears are prevented from becoming reinforcing ribs of the outer wall of the hollow ring.
[0012] The utility model is further configured that a mounting hole is provided at a position of the mounting ear away from the hollow ring.
[0013] By adopting the above technical solution, the hollow ring will not protrude from the outer surface of the conductive tube and affect the appearance of the conductive tube.
[0014] The utility model is further configured such that the sum of the widths of the clamping platforms at the ends of the first tube body and the second tube body is smaller than the width of the hollow ring.
[0015] By adopting the above technical solution, the sealing performance of the connection between the first tube body and the second tube body is further improved.
[0016] The utility model is further configured that a sealing gasket is sleeved between the hollow ring and the clamping platform, and the width of the sealing gasket is equal to the sum of the widths of the clamping platforms at the ends of the first tube body and the second tube body.
[0017] By adopting the above technical solution, the sealing performance of the connection of the first conductive tube is further improved.
[0018] The utility model is further configured such that the length of the external thread column is greater than that of the internal thread column.
[0019] By adopting the above technical solution, the connection between the first tube body and the second tube body is made tighter.
[0020] In summary, the utility model mainly has the following beneficial effects:
[0021] The utility model provides a conical boss and a concave boss structure between the thread structures of the two conductive tubes that are connected in opposite directions. When the two conductive tubes are threadedly connected, the conical boss and the concave boss are mutually squeezed and matched to achieve a sealing and waterproofing effect. A hollow ring structure is sleeved at the connection between the two conductive tubes. The extrusion generated when the two conductive tubes are connected to each other causes the hollow ring to deform. The deformed hollow ring squeezes the gap between the two conductive tubes, thereby further improving the sealing performance of the conductive tube connection.
[0022] The utility model fixes the mounting ear structure on the hollow ring and utilizes the mounting holes on the mounting ears to conveniently realize the installation of the conductive tube. At the same time, the mounting ears are connected to the hollow ring by means of fixing plates connected on both sides. Under the premise of not affecting the deformation of the hollow ring, the connection strength of the mounting ears is effectively improved, so that the conductive tube can be installed more stably.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0031] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1
[0032] A conductive tube sealing pipe connection structure, such as Figure 1-6 As shown, it includes a first tube body 1 and a second tube body 2. The ends of the first tube body 1 and the second tube body 2 that are close to each other are both provided with an annular clamping platform 8. One end of the first tube body 1 is fixedly connected with a frustum 4, and an external threaded column 6 is connected along the frustum 4. The inner wall of one end of the second tube body 2 is provided with a conical groove 5 that fits with the frustum 4, and an internal threaded column 7 that cooperates with the external threaded column 6 is provided along the conical groove 5. The length of the external threaded column 6 is greater than that of the internal threaded column 7, so that the internal threaded column 7 can be fully utilized. When the first tube body 1 and the second tube body 2 are connected to each other, the connection between the first tube body 1 and the second tube body 2 is made tighter. A hollow ring 3 is clamped on the clamping platform 8 between the first tube body 1 and the second tube body 2.
[0033] See also Figure 2-6A sealing gasket 9 is also provided between the hollow ring 3 and the clamping platform 8. The width of the sealing gasket 9 is equal to the sum of the widths of the clamping platforms 8 at the ends of the first tube body 1 and the second tube body 2. The sealing gasket 9 is padded at the clamping platform 8 between the first tube body 1 and the second tube body 2, effectively covering the gap at the connection between the first tube body 1 and the second tube body 2. At the same time, under the deformation and extrusion of the hollow ring 3, the sealing gasket 9 can be more evenly attached to the gap at the connection between the first tube body 1 and the second tube body 2, further improving the sealing performance of the connection between the first conductive tube.
[0034] See also Figure 2-6 The sum of the widths of the clamping platforms 8 at the ends of the first tube body 1 and the second tube body 2 is smaller than the width of the hollow ring 3, so that when the first tube body 1 is connected to the second tube body 2, the clamping platforms 8 of the first tube body 1 and the second tube body 2 squeeze the two side walls of the hollow ring 3, causing the hollow ring 3 to deform and bulge. The bulged hollow ring 3 can well fill the gap at the interface between the first tube body 1 and the second tube body 2, further improving the sealing performance of the connection between the first tube body 1 and the second tube body 2. Embodiment 2
[0035] A conductive tube sealing pipe connection structure, such as Figure 1-6 As shown, on the basis of embodiment 1, the difference from embodiment 1 is that both ends of the outer wall of the hollow ring 3 are fixedly connected with a plurality of mutually corresponding fixing plates 10, and a mounting ear 11 is connected between two mutually corresponding fixing plates 10, and the length direction of the mounting ear 11 is consistent with the diameter direction of the hollow ring 3. The mounting ear 11 connected to the fixing plate 10 is used to conveniently install the spliced conductive tube on the required installation surface, and the mounting ear 11 is provided with a mounting hole 13 at a position away from the hollow ring 3. The mounting hole 13 on the mounting ear 11 is passed through a screw or a wall nail to install the conductive tube on the required installation surface. Specifically, the diameter of the outer wall of the hollow ring 3 is the same as the diameter of the outer wall of the first tube body 1 and the second tube body 2, so that the hollow ring 3 will not protrude from the outer surface of the conductive tube and affect the appearance of the conductive tube.
[0036] See also Figure 1-2 A notch 12 is provided at a position of the mounting ear 11 close to the hollow ring 3. The notch 12 on the mounting ear 11 can prevent the mounting ear 11 from contacting the middle of the hollow ring 3 and affecting the deformation of the hollow ring 3, and prevent the mounting ear 11 from becoming a reinforcing rib plate of the outer wall of the hollow ring 3.
[0037] The working principle of the utility model is as follows: the sealing gasket 9 and the hollow ring 3 are sleeved on the clamping platform 8 of the first tube body 1 or the second tube body 2, and then the first tube body 1 and the second tube body 2 are rotated and connected by using the threaded connection structure of the external thread column 6 and the internal thread column 7 between the first tube body 1 and the second tube body 2. Before the cone 4 and the cone groove 5 contact each other, the clamping platform 8 of the first tube body 1 and the second tube body 2 has begun to squeeze the side wall of the hollow ring 3 to deform the hollow ring 3. The inner wall and the outer wall of the hollow ring 3 in the deformed state are both in a bulging state. The raised inner wall of the hollow ring squeezes the sealing gasket 9, which has a good sealing effect on the joint between the first tube body 1 and the second tube body 2. As the first tube body 1 and the second tube body 2 continue to rotate relative to each other, when the first tube body 1 and the second tube body 2 complete the threaded connection, the cone 4 and the cone groove 5 are tightly fitted, further improving the sealing of the conductive ring connection.
[0038] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
