[0002] The connecting head of metal pipe fittings, also known as pipe joint or pipe fitting connector, is a metal fitting used to connect different building pipes or pipe fittings to achieve the transmission and distribution of fluids (such as water, gas, etc.).

[0003] In the prior art, for the connection between metal elbow pipes and metal straight pipes, the disassembly and adjustment are mostly carried out through the screws and nuts on the fixing parts, so as to improve the stability of the connection between metal elbow pipes and metal straight pipes.

[0004] There are still some problems in the actual application of the above scheme. In some usage scenarios, when the pipeline needs to work in a humid area for a long time, due to the influence of factors such as humid air, the nuts and screws will rust. And the rusting of the nuts and screws will increase the friction force between the nuts and screws, making it necessary to use greater force and longer time for disassembly, and even the situation of being unable to disassemble may occur.

[0005] Therefore, the utility model provides a connection structure for building pipes. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique.

[0008] As a further technical solution of the utility model, the pressing and disassembly device includes a first fixing block, the first fixing block is slidably connected to the end of the second arc-shaped fixing part far away from the rotating shaft, and a fixing column is fixedly connected to the upper part of the first fixing block.

[0009] As a further technical solution of the present utility model, a guiding column is fixedly connected to one end of the fixing column away from the first fixing block. A plurality of fixing grooves are equidistantly arranged on the outer ring surface of the guiding column. An arc-shaped clamping block is fixedly connected to the end of the guiding column away from the fixing column.

[0010] As a further technical solution of the present utility model, a moving block is slidably connected to the outer ring surface of the guiding column.

[0011] As a further technical solution of the present utility model, the pressing and disassembling device further includes a second fixing block. The second fixing block is fixedly connected to one end of the first arc-shaped fixing member away from the rotating shaft. A reciprocating cylinder column is fixedly connected to the top of the second fixing block. An inner cavity is provided inside the reciprocating cylinder column.

[0012] As a further technical solution of the present utility model, a guiding groove is penetrated and opened in the middle of one side of the second fixing block away from the first arc-shaped fixing member.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. For the connection structure for building pipes of the present utility model, by manually sleeving the first arc-shaped fixing member and the second arc-shaped fixing member at the junction of the L-shaped connector and the metal straight pipe. At this time, by pressing down the first arc-shaped fixing member, the first arc-shaped fixing member rotates around the rotating shaft. While the first arc-shaped fixing member rotates, the other components connected to the first arc-shaped fixing member also move with the rotation of the first arc-shaped fixing member. At this time, the arc-shaped clamping block enters the reciprocating cylinder column through the guiding hole opened at the bottom of the second fixing block. At the same time, the arc at the top of the arc-shaped clamping block pushes the moving sliding rod and the inclined clamping block along the guiding of the guiding groove to the side away from the first arc-shaped fixing member. When the arc-shaped clamping block completely falls into the reciprocating cylinder column, the adjustment is completed by pulling the moving sliding rod and the reset spring and cooperating with the multiple groups of fixing grooves opened on the outer ring surface of the guiding column. At this time, the inclined clamping block is stuck inside the fixing groove, thus completing the fixing work of the L-shaped connector and the metal straight pipe, and at the same time avoiding the situation that the pipeline is damaged due to the staff over-tightening the screw and nut.

[0017] 2. For the connection structure for building pipes of the present utility model, by pulling the movable sliding rod and the inclined clamping block away from the first arc-shaped fixing member, the inclined clamping block can be disengaged from the guide groove formed on the outer ring surface of the guide post. At this time, by manually opening the first arc-shaped fixing member by the staff, it can be disassembled and replaced more easily and quickly, which greatly shortens the maintenance time and improves the maintenance efficiency.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1:

[0027] Please refer to Figures 1 to 5, A connection structure for building pipes, including a pipe fixing device 1. The pipe fixing device 1 includes an L-shaped connector 101. One end of the L-shaped connector 101 is fixedly connected to a metal straight pipe 102. The pipe fixing device 1 further includes a first arc-shaped fixing member 103. One end of the first arc-shaped fixing member 103 is fixedly connected to a rotating shaft 104. The outer ring surface of the rotating shaft 104 is rotatably connected to a second arc-shaped fixing member 105. The first arc-shaped fixing member 103 and the second arc-shaped fixing member 105 are sleeved at the junction of the L-shaped connector 101 and the metal straight pipe 102. One end of the first arc-shaped fixing member 103 and the second arc-shaped fixing member 105 away from the rotating shaft 104 is provided with a pressing and disassembling device 2, and the pressing and disassembling device 2 is used for quick disassembly in the later stage.

[0028] Specifically, when the pipe needs to work in a humid area for a long time, due to the influence of factors such as water vapor, the nut and the screw will rust. The rusting of the nut and the screw will increase the friction between the nut and the screw, resulting in the need for greater force and longer time for disassembly, and even the situation of being unable to disassemble.

[0029] In this embodiment, the first arc-shaped fixing member 103, the rotating shaft 104 and the second arc-shaped fixing member 105 are manually sleeved at the junction of the L-shaped connector 101 and the metal straight pipe 102. At the same time, the fixing of the first arc-shaped fixing member 103 and the second arc-shaped fixing member 105 is completed through the screw and the nut. However, since the screw and the nut will rust when working in a humid environment for a long time, it will lead to the need for greater force and longer time for disassembly in the later stage, and even the situation of being unable to disassemble. At this time, by replacing the pressing and disassembling device 2, the components in the pressing and disassembling device 2 are directly pulled to achieve the purpose of quick disassembly.

[0030] Embodiment 2: Compared with Embodiment 1, another implementation manner of the present invention is as follows:

[0031] As Figure 4 shown, one end of the fixing column 202 away from the first fixing block 201 is fixedly connected to a guiding column 203. A plurality of fixing grooves 204 are equidistantly arranged on the outer ring surface of the guiding column 203. One end of the guiding column 203 away from the fixing column 202 is fixedly connected to an arc-shaped clamping block 205.

[0032] As Figure 4 shown, the pressing and disassembling device 2 further includes a second fixing block 207. The second fixing block 207 is rotatably connected to one end of the first arc-shaped fixing member 103 away from the rotating shaft 104. The top of the second fixing block 207 is fixedly connected to a reciprocating cylinder column 208, and an inner cavity is opened inside the reciprocating cylinder column 208.

[0033] As Figure 4As shown, a guiding groove 209 is penetratingly formed in the middle of the side of the second fixing block 207 away from the first arc-shaped fixing member 103.

[0034] As Figure 4 shown, a moving slide bar 210 is slidably connected inside the guiding groove 209, and a reset spring 211 is fixedly connected to the side of the guiding groove 209 away from the first arc-shaped fixing member 103.

[0035] As Figure 4 shown, one end of the reset spring 211 close to the first arc-shaped fixing member 103 is fixedly connected to an inclined block 212, the inclined block 212 is fixedly connected to one end of the moving slide bar 210 close to the first arc-shaped fixing member 103, and the reset spring 211 is sleeved on the outer ring surface of the transverse rod of the moving slide bar 210.

[0036] Specifically, by pressing down the first arc-shaped fixing member 103, the first arc-shaped fixing member 103 drives the second fixing block 207, the reciprocating cylinder column 208, the guiding groove 209, the moving slide bar 210, the reset spring 211 and the inclined block 212 to move. When the inner wall of the first arc-shaped fixing member 103 fits the outer ring surface at the junction of the L-shaped connector 101 and the metal straight pipe 102, by pushing the second fixing block 207 along the rectangular block on the side of the first arc-shaped fixing member 103 towards the first fixing block 201, during the movement, the fixing column 202 will enter the inner cavity of the reciprocating cylinder column 208 through the guiding opening formed at the bottom of the second fixing block 207. At this time, the arc-shaped structure at the top of the arc-shaped block 205 will move the inclined block 212 and the moving slide bar 210 along the guiding direction of the guiding groove 209 away from the first arc-shaped fixing member 103, and the arc-shaped block 205 will slide into the inner cavity of the reciprocating cylinder column 208. When the arc-shaped block 205 slides into the inner cavity of the reciprocating cylinder column 208, since the diameter of the fixing column 202 is smaller than the bottom diameter of the arc-shaped block 205, the compressed reset spring 211 will reset, and at the same time, it will push the inclined block 212 to move along the guiding direction of the guiding groove 209 towards the first arc-shaped fixing member 103. At this time, the inclined block 212 will be stuck at the bottom of the arc-shaped block 205. By continuously pressing down the first arc-shaped fixing member 103, the components of the disassembly device 2 can be pressed down to make the inclined block 212 slide into the fixing grooves 204 at different heights, so as to ensure that the inner sides of the first arc-shaped fixing member 103 and the second arc-shaped fixing member 105 are kept in close contact with the junction of the L-shaped connector 101 and the metal straight pipe 102, avoiding the situation that the pipeline is damaged due to the staff over-tightening the screw and nut.

[0037] As Figure 4 and Figure 5 shown, a moving block 206 is slidably connected to the outer ring surface of the guiding column 203.

[0038] As Figure 4 and Figure 5As shown in the figure, the pressing and disassembling device 2 includes a first fixing block 201, and the first fixing block 201 is rotatably connected to one end of the second arc-shaped fixing member 105 away from the rotating shaft 104. A fixing column 202 is fixedly connected to the upper part of the first fixing block 201.

[0039] Specifically, when it is necessary to disassemble the pressing and disassembling device 2, the staff pulls the moving slide rod 210 along the guide of the guide groove 209 in a direction away from the first arc-shaped fixing member 103. At this time, by pulling the second fixing block 207 upward along the guide of the rectangular block on the side wall of the first arc-shaped fixing member 103, the components on the second fixing block 207 will completely separate from the components on the first fixing block 201. Secondly, by pulling the first arc-shaped fixing member 103 to rotate around the rotating shaft 104, the device can be opened. Through the setting of the first arc-shaped fixing member 103, it can be disassembled and replaced more easily and quickly, which greatly shortens the maintenance time and improves the maintenance efficiency.

[0040] Working principle: By pressing down the first arc-shaped fixing member 103, the first arc-shaped fixing member 103 drives the second fixing block 207, the reciprocating cylinder column 208, the guide groove 209, the moving slide rod 210, the return spring 211 and the inclined block 212 to move. When the inner wall of the first arc-shaped fixing member 103 fits the outer ring surface at the intersection of the L-shaped connector 101 and the metal straight pipe 102, by pushing the second fixing block 207 to move along the rectangular block on the side of the first arc-shaped fixing member 103 towards the first fixing block 201, during the movement, the fixing column 202 will enter the inner cavity of the reciprocating cylinder column 208 through the guiding opening opened at the bottom of the second fixing block 207. At this time, the arc-shaped structure at the top of the arc-shaped block 205 will move the inclined block 212 and the moving slide rod 210 along the guide of the guide groove 209 in a direction away from the first arc-shaped fixing member 103, and the arc-shaped block 205 will slide into the inner cavity of the reciprocating cylinder column 208. When the arc-shaped block 205 slides into the inner cavity of the reciprocating cylinder column 208, since the diameter of the fixing column 202 is smaller than the bottom diameter of the arc-shaped block 205, the compressed return spring 211 will reset, and at the same time, it will push the inclined block 212 to move along the guide of the guide groove 209 towards the first arc-shaped fixing member 103. At this time, the inclined block 212 will be stuck at the bottom of the arc-shaped block 205. By continuously pressing down the first arc-shaped fixing member 103, the components of the pressing and disassembling device 2 can make the inclined block 212 slide into the fixing grooves 204 at different heights, so as to ensure that the inner sides of the first arc-shaped fixing member 103 and the second arc-shaped fixing member 105 can be kept in close contact with the intersection of the L-shaped connector 101 and the metal straight pipe 102, avoiding the situation that the pipeline is damaged due to the staff over-tightening the screw and nut;

[0041] When it is necessary to disassemble the pressing and disassembling device 2, the staff pulls the moving slide bar 210 along the guide of the guide groove 209 in a direction away from the first arc-shaped fixing member 103. At this time, by pulling the second fixing block 207 upward along the guide of the rectangular block on the side wall of the first arc-shaped fixing member 103, the components on the second fixing block 207 will completely disengage from the components on the first fixing block 201. Secondly, by pulling the first arc-shaped fixing member 103 to rotate around the rotating shaft 104, the device can be opened. Through the setting of the first arc-shaped fixing member 103, it can be disassembled and replaced more easily and quickly, which greatly shortens the maintenance time and improves the maintenance efficiency.

[0042] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
