Description

Technical Field

[0001] This utility model relates to the field of pipe support technology, and in particular to a pipe support frame that is easy to store. Background Technology

[0002] A utility model patent with publication number CN 209587352 U and publication date of 2019.11.05 discloses a pipe support, including: a base, a support part, and a height adjustment mechanism; one end of the height adjustment mechanism is connected to the support part, the support part is used to support the pipe, and the height adjustment mechanism is connected to the base. The support height of the pipe support can be adjusted by adjusting the connection position between the height adjustment mechanism and the base.

[0003] When using the pipe support provided by this utility model, the pipe connected to the fan unit is placed on the support part of the pipe support. The operator holds the support part with one hand and adjusts the connection position between the height adjustment mechanism and the base with the other hand until the horizontal height of the pipe is adjusted to meet the test standard. Compared with the prior art, the pipe support is more accurate and saves more time and effort when adjusting the support height.

[0004] However, the utility model has the following two problems in actual use: 1. The legs of the bracket are welded to the fixing plate and the reinforcing plate, so the bracket cannot be further reduced in size when stored, resulting in a large space occupied when stored.

[0005] 2. When adjusting the height, the limit block is rotated by the push rod. The limit block further uses the thread to drive the screw to drive the connecting plate and the support plate to move up and down. However, in this process, when the pipe is placed between the two support plates, the weight of the pipe will increase the friction between the limit block and the fixed plate through the screw, which will make it very difficult to rotate the limit block.

[0006] Therefore, there is an urgent need for an easy-to-store pipe support frame that takes up less space when stored and is easier to adjust in terms of height. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides an easy-to-store pipe support frame, which solves the problem that existing supports cannot be further reduced in size when stored, resulting in a large space occupied during storage and difficulty in adjusting the height.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] An easy-to-store pipe support frame includes a support tube, a plurality of hinge seats are provided on the outer wall of the support tube, a support arm is hinged in the hinge seat, a connecting arm is provided at the end of the support arm away from the hinge seat, a sliding sleeve is slidably fitted on the support tube, and the other end of the connecting arm is connected to the sliding sleeve. When the connecting arm is in a horizontal state, the support arm provides support for the support tube.

[0010] A guide tube is fixed inside the support tube, a screw is installed inside the guide tube, a mounting seat is detachably provided at the top of the screw, clamps are symmetrically provided on the mounting seat, and a nut sleeve is fitted on the screw;

[0011] A bearing is provided at the end of the guide tube and on the bottom side of the nut sleeve. The inner circle of the bearing is connected to the guide tube, and a connecting ring is fitted on the outer circle of the bearing. The connecting ring has multiple connecting holes that extend through it along the height direction. A connecting rod is provided on the nut sleeve at the position corresponding to the connecting holes. A locking element is fitted on the connecting rod. When the nut sleeve rotates around the screw, the connecting rod drives the connecting ring to rotate together.

[0012] Furthermore, the mounting base has T-shaped locking blocks at both ends, and one end of the clamping plate has a reinforcing part. The reinforcing part has a T-shaped locking groove corresponding to the position of the T-shaped locking block, and the included angle between the two clamping plates on the mounting base is 120 degrees.

[0013] Furthermore, the mounting base has a fixing hole in the middle, and the screw has a threaded hole along the axial direction at the position corresponding to the fixing hole. The threaded hole is equipped with a connecting bolt for connecting the screw and the mounting base.

[0014] Furthermore, the mounting base is provided with a trapezoidal pressure block between the two clamping plates. The trapezoidal pressure block is connected to the screw bolt, and the two sides of the trapezoidal pressure block are in contact with the side walls of the clamping plates.

[0015] Furthermore, rubber pads are provided on the side walls of the clamping plate.

[0016] Furthermore, the outer wall of the connecting rod is threaded, and the locking element is a nut that is threadedly connected to the connecting rod.

[0017] Furthermore, the end of the connecting rod has a pin hole perpendicular to the axial direction, and the locking element is a pin that mates with the pin hole.

[0018] Furthermore, the nut sleeve is provided with rotating arms at both ends.

[0019] Furthermore, a countersunk hole is provided in the middle of the trapezoidal pressure block.

[0020] In summary, the beneficial technical effects of this utility model are as follows:

[0021] (1) By utilizing the cooperation of the support arm, hinge seat, connecting arm and sliding sleeve, not only does it provide support for the entire bracket and improve the stability of the bracket when supporting the pipeline, but also the support arm can be folded along the hinge seat when stored, reducing the radius of the virtual circle where the three support arms are located and achieving the effect of being parallel to the support pipe. This further reduces the volume of the bracket when stored and reduces the space occupied. At the same time, by utilizing the connecting ring on the outer circle of the bearing and connecting the nut sleeve to the connecting ring through the connecting rod, when the height is adjusted by rotating the nut sleeve, the nut sleeve can rotate with the outer circle of the bearing, further reducing the friction and making the adjustment more effortless.

[0022] (2) The T-shaped card block and T-shaped card slot realize the detachable connection between the mounting base and the clamp plate, so that the clamp plate can be removed separately when storing. Compared with the fixed connection between the two clamp plates and the mounting base, it effectively avoids the squeezing and deformation of the two clamp plates by other objects when storing.

[0031] The present invention will now be described clearly and completely with reference to the embodiments.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Example 1

[0035] See appendix Figure 1-4 The image shows an easy-to-store pipe support frame, including a support pipe 1. Three hinge seats are welded around the outer wall of the support pipe 1. A support arm 3 is hinged in each hinge seat. The support arm 3 can rotate and open relative to the support pipe 1 along the hinge seat. A connecting arm 4 is hinged to the end of the support arm 3 away from the hinge seat. At the same time, a sliding sleeve 5 is slidably fitted on the support pipe 1. The sliding sleeve 5 is hinged to the other end of the connecting arm 4. In use, when the support arm 3 is opened relative to the support pipe 1, the sliding sleeve 5 slides downward along the support pipe 1. When the connecting arm 4 reaches a horizontal state, the opening angle of the support arm 3 is at its maximum. At this time, the support arm 3 provides support for the support pipe 1. In order to prevent the sliding sleeve 5 from sliding off the support pipe 1, a limit plate 6 is welded to the end of the support pipe 1.

[0036] A guide tube 2 is welded inside the support tube 1. A screw 7 is installed inside the guide tube 2. A mounting seat 15 is installed at the top of the screw 7. Two clamping plates 17 are symmetrically arranged at a 120-degree angle on the mounting seat 15. A rubber pad 20 is provided on the side of the two clamping plates 17 that are close to each other. When in use, the pipe 27 is placed between the two clamping plates 17, and the coating on the outer wall of the pipe 27 can be effectively protected by the rubber pad 20.

[0037] A nut sleeve 8 is provided on the screw 7 through threaded engagement. Rotating arms 9 for rotating the nut sleeve 8 are provided at both ends. A bearing 10 is provided at the end of the guide tube 2 and located on the bottom side of the nut sleeve 8. The inner circle of the bearing 10 is welded and fixed to the guide tube 2. A connecting ring 11 is fitted on the outer circle of the bearing 10. When the outer circle of the bearing 10 is rotated, the connecting ring 11 rotates with it.

[0038] The connecting ring 11 has four connecting holes 26 extending along the height direction. At the same time, the nut sleeve 8 has a connecting rod 12 at the position corresponding to the connecting holes 26. The outer wall of the connecting rod 12 is threaded, and the connecting rod 12 is fitted with a nut 13 through the thread. When the screw 7 is installed into the guide tube 2, the connecting rod 12 passes through the connecting holes 26, and the nut 13 is used to connect the connecting ring 11 and the nut sleeve 8. Then, the nut sleeve 8 is rotated forward and backward by the rotating arm 9. When the nut sleeve 8 rotates, the connecting rod 12 drives the connecting ring 11 to rotate around the bearing 10. Thus, the connecting ring 11 achieves the connection between the nut sleeve 8 and the outer circle of the bearing 10, which reduces the friction when the nut sleeve 8 rotates and makes height adjustment more effortless.

[0039] Furthermore, the mounting base 15 has T-shaped locking blocks 16 at both ends, and the clamping plate 17 has a reinforcing part 18 with a right-angled triangular cross section at one end. The reinforcing part 18 has a T-shaped slot 19 at the position corresponding to the T-shaped locking block 16. The mounting base 15 and the clamping plate 17 are detachably connected through the cooperation of the T-shaped locking block 16 and the T-shaped slot 19. At the same time, a fixing hole 22 is opened in the middle of the mounting base 15, and the screw 7 has a threaded hole 21 along the axial direction at the position corresponding to the fixing hole 22. A connecting bolt 23 is provided in the threaded hole 21. The mounting base 15 and the screw 7 are fixed by the connecting bolt 23.

[0040] Furthermore, to prevent the clamping plate 17 from sliding off the mounting base 15 along the T-shaped locking block 16, a trapezoidal pressure block 24 is provided between the two clamping plates 17 in the mounting base 15. A countersunk hole 25 is provided in the middle of the trapezoidal pressure block 24. The countersunk hole 25, the fixing hole 22, and the threaded hole 21 are concentric. When in use, the trapezoidal pressure block 24 is placed between the two clamping plates 17. At this time, the two sides of the trapezoidal pressure block 24 are respectively attached to the side walls of the clamping plates 17. Then, the connecting bolt 23 is passed through the countersunk hole 25 and the fixing hole 22 in sequence and connected to the threaded hole 21. The trapezoidal pressure block 24 can exert a downward squeezing force on the clamping plates 17 at both ends, so that the T-shaped locking groove 19 and the T-shaped locking block 16 fit more tightly. At this time, the nut of the connecting bolt 23 is placed in the countersunk hole 25 and the end is flush with the trapezoidal pressure block 24, so that when the pipe 27 is placed between the clamping plates 17, the contact area between the pipe 27 and the two clamping plates 17 and the trapezoidal pressure block 24 is larger.

[0041] See appendix for usage. Figure 5 Appendix Figure 6As shown, firstly, the three support arms 3 on the support tube 1 are opened outwards, so that the connecting arm 4 is in a horizontal state. Then, the pipe 27 is placed between the two clamps 17 to achieve the support effect. Then, the nut sleeve 8 is rotated by the rotating arm 9. The rotation of the nut sleeve 8 drives the screw 7 to move up and down along the guide tube 2 through the thread. The screw 7 further drives the top mounting seat 15 and clamp 17 to move up and down. During this period, the nut sleeve 8 is connected to the outer circle of the bearing 10 through the connecting ring 11. The bearing 10 reduces the friction when the nut sleeve 8 rotates, making the rotation resistance smaller and the adjustment easier. When storing, the sliding sleeve 5 is pushed upwards along the support tube 1. At this time, the connecting arm 4 pulls the support arm 3 to rotate inward along the hinge seat, so that the support arm 3 is in a parallel state relative to the support tube 1 to achieve storage. This reduces the volume of the entire bracket and reduces the space occupied during storage.

[0042] Another beneficial effect of this utility model is that by setting the clamping plate 17 and the mounting base 15 to a detachable connection, the entire bracket can be disassembled into individual parts during storage and transportation, thus further reducing the volume. More importantly, it avoids the compression and deformation of the two clamping plates 17 by external objects, which would cause the angle between the two to change. At the same time, by setting a right-angled triangular reinforcement 18 at the joint between the clamping plate 17 and the mounting base 15, the support strength of the pipe 27 after it falls between the two clamping plates 17 is enhanced, preventing the clamping plates 17 from expanding and deforming outward.

[0043] Example 2

[0044] See appendix Figure 7 As shown, unlike Embodiment 1, in Embodiment 2, the end of the connecting rod 12 is provided with a pin hole perpendicular to the axis direction, and a pin 14 is provided in the pin hole. When the nut 13 sleeve 8 is connected to the connecting ring 11, the connecting rod 12 is passed through the connecting hole 26, and then the pin 14 is inserted into the pin hole.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
