Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning system installation, in particular to a pipeline bracket. Background Art

[0002] The design and form selection of the pipe support structure is an important part of the air-conditioning system pipe design. In addition to supporting the weight of the pipe, the pipe support can balance the force of the pipe system, limit the displacement of the pipe and absorb vibration.

[0042] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] Embodiment 1 of the present utility model: Figure 1 - Figure 2 and Figure 5 As shown, the utility model proposes a pipe bracket, including an inverted spring piece 1, a pipe clamp 3 and a connecting component 2; the inverted spring piece 1 is connected to the pipe clamp 3 to form a fastening structure for fixing the pipe 4, and the formed fastening structure can fix the pipe 4 from the circumferential direction of the pipe 4, and the fixation of the pipe 4 is more firm; the connecting component 2 is fixedly installed in the middle of the inverted spring piece 1 and is located on the side away from the pipe 4, and the connecting component 2 cooperates with the fastening structure to support the pipe 4. When installed and used, as an embodiment, the connecting component 2 can be directly fixedly connected to the main body of the building. As another embodiment, the connecting component 2 can also be connected to the cross arm 5 of the bracket, and the bracket is fixed to the main body of the building through fasteners.

[0044] The inverted spring piece 1 has two states: a first state, i.e., a concave state ready to embrace the pipe 4; when in the concave state, the concave side 12 of the inverted spring piece 1 faces away from the pipe 4, and an opening is formed on the fastening structure; that is, the concave side 12 of the inverted spring piece 1 faces the connecting component 2, and the inverted spring piece 1 is in a natural state at this time, and an opening is formed on the fastening structure, and the formed opening facilitates the pipe 4 to be placed into the fastening structure through the opening.

[0045] The second state is the convex state that embraces the pipe 4. When in the convex state, the concave side 12 of the recurved spring piece 1 faces the pipe 4, and the fastening structure embraces the outer periphery of the pipe 4; that is, the concave side 12 of the recurved spring piece 1 is away from the connecting assembly 2, and the pipe clamp 3 and the recurved spring piece 1 can be fastened to the outer periphery of the pipe 4. The pipe clamp 3 includes a first clamp 31 and a second clamp 32. The two ends of the recurved spring piece 1 are respectively connected to the first clamp 31 and the second clamp 32, and the connection method can be a fixed connection or a hinged connection. It should be pointed out that the recurved spring piece 1 referred to in this embodiment refers to a long strip structure with two stable shapes. Generally, its two shapes correspond to the aforementioned concave state and convex state, respectively. That is, the recurved spring piece 1 has two stable structures of positive bending and reverse bending; in the above two states, the recurved spring piece 1 is an arc structure, but its bending direction is opposite. The principle of the recurved spring piece 1 is the same as that of the snap ring in the prior art, and the difference is only that the length direction and the bending degree are different in the two states. It should be pointed out that in this embodiment, the concave side 12 is related to the shape of the recurved spring piece 1, that is, it refers to the inner side of the recurved spring piece 1 in the bent state.

[0046] As a preferred embodiment, the first hoop clamp 31 and the second hoop clamp 32 are both hinged to the recurved spring piece 1. Furthermore, the first hoop clamp 31 and the second hoop clamp 32 are connected to the recurved spring piece 1 through a hinge 7. The first hoop clamp 31 is provided with a first clamping portion 311 at one end away from the recurved spring piece 1, and the second hoop clamp 32 is provided with a second clamping portion 321 adapted to the first clamping portion 311 at one end away from the recurved spring piece 1. When the pipeline is installed, the recurved spring piece 1 is in the first state, and the pipeline 4 is placed into the fastening structure through the opening on the fastening structure. The recurved spring piece 1 is pressed down to produce reverse deformation and form a recurved force. At the same time, the first clamping portion 311 of the first hoop clamp 31 is engaged with the second clamping portion 321 of the second hoop clamp 32, so that the first hoop clamp 31, the second hoop clamp 32, and the recurved spring piece 1 are fastened to the pipeline 4. At this time, the recurved spring piece 1 is in the second state. In this way, the installation and fixation of the pipeline 4 can be completed quickly.

[0047] Of course, the pipe clamp 3 may also include only one first clamp 31 or one second clamp 32. When it includes only one first clamp 31 or one second clamp 32, one end of the first clamp 31 or the second clamp 32 is hinged or fixedly connected to one end of the recurved spring sheet 1, and the other end is clamped to the other end of the recurved spring sheet 1.

[0048] As a preferred embodiment, the first clamping portion 311 is a bayonet opening along the length direction of the first clamp 31, and the second clamping portion 321 is a tongue engaging with the bayonet opening. The first clamp 31 and the second clamp 32 may also be connected in other quick connection ways, such as by a spring buckle.

[0049] Embodiment 2 of the present utility model:

[0050] See also Figure 1 - Figure 6 As shown, this embodiment is a further improvement on the basis of the first embodiment, and the same parts as the first embodiment are not repeated here, and only the improved points are described.

[0051] In order to achieve convenient and rapid connection with the cross arm 5 and improve the efficiency of installation, the following measures are taken in this embodiment. The connecting assembly 2 includes a connecting rod 21, an elastic member 22, an elastic self-locking baffle 23 and a lock head 24. One end of the connecting rod 21 is fixedly connected to the recurved spring piece 1. The other end is fixedly connected to the lock head 24; the elastic member 22 and the elastic self-locking baffle 23 are both sleeved on the connecting rod 21, and the elastic member 22 is located between the recurved spring piece 1 and the elastic self-locking baffle 23, and the elastic self-locking baffle 23 is slidably connected to the connecting rod 21. The elastic member 22 can be a spring, and the elastic member 22 can be directly sleeved on the connecting rod 21 without being connected to the recurved spring piece 1 and the elastic self-locking baffle 23. When the elastic self-locking baffle 23 is pushed along the connecting rod 21 toward the recurved spring piece 1, the elastic member 22 is compressed, and the two ends of the elastic member 22 are respectively against the recurved spring piece 1 and the elastic self-locking baffle 23. Of course, both ends of the elastic member 22 may also be connected to one of the inverse spring piece 1 and the elastic self-locking baffle 23 , or both of them.

[0052] The lock head 24 cooperates with a lock nut 6, and the lock nut 6 is installed on the cross arm 5 of the bracket. A mounting groove 51 is provided on one side of the cross arm 5, and the cross section of the mounting groove 51 is C-shaped. The lock nut 6 is installed in the mounting groove 51. In specific implementation, the mounting groove 51 can be provided on the side of the cross arm 5 facing upward, and a baffle 53 is provided at an opposite edge of the notch of the mounting groove 51 along the length direction of the cross arm 5. The sides of the two baffles 53 close to each other are bent toward the bottom of the groove of the mounting groove 51 to form a flange. In order to facilitate the installation of the lock nut in the mounting groove 51, an installation port 52 can be provided at the notch of the mounting groove 51. As an embodiment, the cross arm 5 can also be made of a C-shaped steel pipe.

[0053] The pipe 4 can be quickly fixed on the cross arm 5 of the bracket by plugging and matching the lock head 24 with the lock nut 6. When in use, the connecting rod 21 applies pressure to the lock nut 6. As the connecting rod 21 gradually moves toward the lock nut 6, the elastic self-locking baffle 23 contacts the cross arm 5, and the elastic member 22 is gradually compressed. When the lock head 24 is engaged with the lock nut 6, the elastic member 22 is in a compressed state, and the elastic self-locking baffle 23 is firmly pressed on the cross arm 5 under the reaction force of the elastic member 22, completing the installation and fixation of the pipe 4 on the cross arm 5.

[0054] To further meet the needs of capacity expansion, the installation groove 51 can be opened along the length direction of the cross arm 5 to have the same length as the cross arm 5. To facilitate the installation of the lock nut 6, in addition to opening the installation opening 52 at the notch of the installation groove 51, both ends of the installation groove 51 can also be set as through grooves. Multiple lock nuts 6 can be installed in the installation groove 51 according to the needs of capacity expansion.

[0055] As a preferred embodiment, the lock nut 6 includes two support plates 61 arranged in parallel, and a third clamping portion 62 is provided on opposite sides of the two support plates 61. A clamping path for the lock head 24 to pass through is formed between the two opposite third clamping portions 62. The third clamping portion 62 has a certain elasticity. When subjected to a squeezing force toward the bottom of the mounting groove 51, it can be deformed toward the bottom of the mounting groove 51, so that the lock head 24 can be clamped with the third clamping portion 62 after passing through the clamping path. After the lock head 24 passes through the clamping path, the external force is removed, and under the action of the elastic force of the elastic member 22, one end of the lock head 24 close to the connecting rod 21 is pressed against the end face of the third clamping portion 62 close to the bottom of the mounting groove 51, completing the matching between the lock head 24 and the lock nut 6.

[0056] In order to further improve the locking strength, a multi-stage lock may be provided in the lock nut 6 . Specifically, there are multiple third clamping parts 62 , and the multiple third clamping parts 62 are provided along the direction in which the lock head 24 is inserted into the lock nut 6 .

[0057] The cross section of the lock head 24 is rectangular or trapezoidal. When the lock head 24 is trapezoidal, the large end of the trapezoid is located at a side close to the connecting rod 21, and the small end is located at a side away from the connecting rod 21.

[0058] A rubber gasket 11 is fixedly mounted on the side of the recurved spring piece 1 that contacts the pipe 4 .

[0059] The utility model connects the recurved spring piece 1 with the pipe clamp 3 to form a fastening structure for fixing the pipe 4. The connection assembly 2 is plugged with the lock nut 6 installed on the cross arm 5. No bolts or nuts are required. The pipe can be quickly locked on site by manual pressing. It has the characteristics of flexible deployment, high quality and fast, and can realize fast and safe installation and deployment on the construction site, greatly reducing labor costs. In addition, a rubber gasket 11 is set on the recurved spring piece 1 to abandon the anticorrosive wooden support structure.

[0060] There are two installation methods for the installation process of the pipe 4. In the first installation method, the first step is to install the pipe 4 in the fastening structure formed by connecting the recurved spring piece 1 and the pipe clamp 3. During installation, it is only necessary to press the pipe 4 to make the recurved spring piece 1 deform in the opposite direction to form a reaction force. The first clamp 31 and the second clamp 32 can be manually assisted to rotate so that the bayonet of the first clamp 31 is engaged with the tongue of the second clamp 32; the second step is to install the lock nut 6 into the installation groove 51 on the cross arm 5, and adjust the position of the lock nut 6 in the installation groove 51 as needed; the third step is to insert the lock head 24 on the connecting rod 21 of the pipe 4 installed in the first step into the lock nut 6 to complete the installation of the pipe. The second installation method, the first step is to install the lock nut 6 into the installation groove 51 on the cross arm 5, and adjust the position of the lock nut 6 in the installation groove 51 as needed; the second step is to install the fastening structure formed by connecting the reverse curved spring piece 1 and the pipe clamp 3 to the cross arm 5 through the cooperation of the lock head 24 and the lock nut 6; the third step is to install the pipe 4 in the fastening structure formed by connecting the reverse curved spring piece 1 and the pipe clamp 3.

[0061] Disassembly process of pipe 4: press the bracket to unlock and disengage the lock head 24 from the lock nut 6, manually move the lock head 24 horizontally along the installation groove 51 in the lock nut 6, and after being removed from the lock nut 6, the lock head 24 pops out automatically under the elastic force of the elastic member 22, and then open the clamping point between the first hoop clamp 31 and the second hoop clamp 32, and the recurved spring piece 1 returns to the first state under the action of its own elastic force, and then take the pipe 4 out of the opening of the fastening structure to complete the disassembly of the pipe 4. The disassembled pipe bracket can be recycled and reused.

[0062] In order to facilitate the removal of the lock head 24 from the lock nut 6, at least one side between the two support plates 61 of the lock nut 6 is open along the length direction of the installation groove 51. In this way, when the bracket is pressed to unlock and disengage the lock head 24 from the lock nut 6, the lock head 24 can be manually pushed to move along the direction of the installation groove 51 to disengage the lock head 24 from the third clamping portion 62.
