Description

Technical Field

[0001] This utility model belongs to the field of fire sprinkler branch pipe technology, and more specifically, it relates to a positioning and clamping mechanism for fire sprinkler branch pipe. Background Technology

[0002] Fire sprinkler branch pipes, also known as terminal drainage pipes of fire sprinkler fire prevention systems, are an important component of fire sprinkler fire prevention systems. They are usually used in conjunction with main pipelines and sprinkler heads. During the construction and installation of fire sprinkler branch pipes, it is necessary to position and clamp the fire sprinkler branch pipes to support them and keep them stable, so as to facilitate the connection between fire sprinkler branch pipes.

[0003] Application number CN202322899050.5 discloses a positioning and clamping mechanism for fire sprinkler branch pipes, including a base plate and a fixed chamber. Two movable seats are slidably connected inside the fixed chamber. A support ring is fixedly connected to the top of each movable seat. A positioning component is provided on the support ring. An adjusting component is provided on the fixed chamber. The positioning component includes a driven gear rotatably connected to the outside of the support ring. Three fixed frames are fixedly connected to the outside of the support ring, and a rotating rod is rotatably connected inside each fixed frame. This fire sprinkler branch pipe positioning and clamping mechanism, by setting the positioning component, enables the positioning of the fire sprinkler branch pipe by placing it inside the support ring, then activating a second motor to move the three fixed plates. The three fixed plates cooperate to position and fix the fire sprinkler branch pipe, keeping it stable and making the fixing of the fire sprinkler branch pipe more convenient and stable.

[0004] Based on the above patent search and understanding of the application of existing fire sprinkler branch pipe positioning and clamping mechanisms: Currently, most fire sprinkler branch pipes are assembled by connecting two pipes, and there is no force point at the installation position. Therefore, during the process of shaking between the two pipes, it is easy for the two pipes to break apart. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fire sprinkler branch pipe positioning and clamping mechanism, which solves the problem that most existing fire sprinkler branch pipes are connected between two pipes during assembly, and there is no force point at the installation position. Therefore, during the process of shaking between the two pipes, the two pipes are prone to breakage.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A positioning and clamping mechanism for a fire sprinkler branch pipe includes a positioning seat; a protrusion is fixedly installed at the middle position of the top of the positioning seat, and the middle position of the protrusion is rotatably connected to the middle position of a double-ended screw. A sliding block is slidably connected at the front and rear ends of the top of the positioning seat. The two sliding blocks are symmetrically designed, and a threaded hole is opened at the lower position of each sliding block. The threaded holes of the two sliding blocks are designed in opposite directions. The left and right sides of the double-ended screw are respectively located in the threaded holes of one of the sliding blocks.

[0008] According to one embodiment of the present invention, a clamping sleeve is fixedly installed at the top position of each sliding block. The two clamping sleeves are symmetrically designed, and a bevel gear is rotatably connected to the upper part of the interior of each clamping sleeve. A hexagonal groove is provided at the top position of the bevel gear.

[0009] According to one embodiment of the present invention, the middle position of each clamping sleeve is a through-type design, and a bevel gear ring is rotatably connected inside the clamping sleeve. The upper inner side of the bevel gear ring meshes with a bevel gear for transmission, and a spiral groove is provided on the outer side of the bevel gear ring.

[0010] According to one embodiment of the present invention, a sliding groove is provided at the left and right ends of the outer side of the clamping sleeve, and an L-shaped adjusting member is slidably connected in the sliding groove of the clamping sleeve. The rear end of each L-shaped adjusting member is engaged with the spiral groove of the bevel gear ring for transmission.

[0011] According to one embodiment of the present invention, each of the L-shaped adjusting members has a threaded hole on its side, and a bolt is rotatably connected in the threaded hole of each L-shaped adjusting member, and an arc-shaped clip is rotatably connected to the inner side of each bolt.

[0012] According to one embodiment of the present invention, a fire-fighting pipe is inserted into the interior of each of the two clamping sleeves, and the two fire-fighting pipes are in contact with each other.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. After connecting the two fire-fighting pipes using traditional bolting methods, rotate the two bevel gears. The bevel gears will drive the bevel gear ring to rotate, and the bevel gear ring will drive the two L-shaped adjusting parts that are meshed with it to move towards each other until the inner sides of the two arc-shaped clips are in contact with the two sides of the fire-fighting pipes. This provides auxiliary support for the installation position of the two fire-fighting pipes and avoids the situation where there is no point of force during the connection of the two pipes.

[0015] 2. After the two fire pipes are connected and the positioning seat is installed, the positioning seat can be supported and connected to the wall and the ground, thereby increasing the force points at the connection point of the two fire pipes.

[0016] 3. When there is no fixing measure between two fire pipes and they need to be installed together, the two fire pipes are first limited by the arc-shaped clamp. Then, the double-ended screw is rotated. Through the cooperation of the double-ended screw and the sliding block, the two sliding blocks can slide towards each other above the positioning seat until the two fire pipes are close together and tightly fitted, thus increasing the means of fastening the installation between the two fire pipes.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a positioning and clamping mechanism for fire sprinkler branch pipes, including a positioning seat 1; a protrusion 101 is fixedly installed at the middle position of the top of the positioning seat 1, and the middle position of the protrusion 101 is rotatably connected to the middle position of the double-ended screw 102. A sliding block 103 is slidably connected to the front and rear ends of the top of the positioning seat 1, the two sliding blocks 103 are symmetrically designed, and a threaded hole is opened at the lower part of each sliding block 103. The threaded holes of the two sliding blocks 103 are designed in opposite directions. The left and right sides of the double-ended screw 102 are respectively located in the threaded holes of one of the sliding blocks 103. A clamping sleeve 104 is fixedly installed at the top of each sliding block 103, the two clamping sleeves 104 are symmetrically designed, and a bevel gear 105 is rotatably connected to the upper part of the inside of each clamping sleeve 104. A hexagonal groove is provided at the top of the bevel gear 105.

[0029] Each clamping sleeve 104 has a through-type design in the middle, and a bevel gear ring 106 is rotatably connected inside the clamping sleeve 104. The upper inner side of the bevel gear ring 106 meshes with a bevel gear 105 for transmission. A spiral groove is provided on the outer side of the bevel gear ring 106. A sliding groove is provided at the left and right ends of the outer side of the clamping sleeve 104, and an L-shaped adjusting member 107 is slidably connected in the sliding groove of the clamping sleeve 104. The rear end of each L-shaped adjusting member 107 meshes with the spiral groove of the bevel gear ring 106 for transmission.

[0030] Each L-shaped adjusting component 107 has a threaded hole on its side, and a bolt 108 is rotatably connected in the threaded hole of each L-shaped adjusting component 107. An arc-shaped clip 109 is rotatably connected to the inner side of each bolt 108. A fire pipe 2 is passed through the inner part of each of the two clamping sleeves 104, and the two fire pipes 2 are in contact with each other.

[0031] In use: When assembling the two fire-fighting pipes 2, first, thread the two fire-fighting pipes 2 through the inside of the two clamping sleeves 104 respectively. Then, connect the two fire-fighting pipes 2 using the traditional bolting method. Next, rotate the two bevel gears 105 respectively. The bevel gears 105 will drive the bevel gear ring 106 to rotate. The bevel gear ring 106 will drive the two L-shaped adjusting parts 107 that are meshed with it to move towards each other until the inner side of the two arc-shaped clamps 109 is in contact with the two sides of the fire-fighting pipes 2. This provides auxiliary support for the installation position of the two fire-fighting pipes 2, thereby avoiding the situation where there is no force point during the connection of the two pipes.

[0032] After the two fire pipes 2 are connected and the positioning seat 1 is installed, the positioning seat 1 can be used to support the connection between the wall and the ground, thereby increasing the force points at the connection point of the two fire pipes 2.

[0033] When there is no fixing measure between the two fire pipes 2 and they need to be connected for installation, the two fire pipes 2 are first limited by the arc-shaped clip 109. Then, the double-ended screw 102 is rotated. Through the cooperation of the double-ended screw 102 and the sliding block 103, the two sliding blocks 103 can slide towards each other above the positioning seat 1 until the two fire pipes 2 are close together and tightly fitted, thus increasing the means of fastening the installation between the two fire pipes 2.

While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments.
