Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a quick fixing device for pipes buried in buildings and a method for using the device. Background Art

[0002] During construction, it is often necessary to open grooves on the walls. The main purpose of the grooves is to bury wire pipes. After the wire pipes are buried, the cables are then passed through. This installation method makes it easy to replace the cables later, which brings convenience to the later work.

[0003] However, when installing cable conduits, they are typically tied and secured within the trench, but this can lead to insecure fixation. Furthermore, the cable conduits are made of plastic and have a certain degree of elasticity. Therefore, when covering the concrete, the conduits sway, preventing the concrete from effectively filling the gap between the rear end of the conduits and the trench. This results in the formation of voids after the concrete dries. After a certain number of years of use, cracks may occur in the wall where the conduits are located, affecting their usability. Furthermore, these gaps are also susceptible to entry by pests such as rats and cockroaches. Therefore, a rapid fixing device for buried pipes in buildings is urgently needed. Summary of the Invention

[0004] In order to solve the above problems in the prior art, a quick fixing device for pipes buried in a building and a method for using the same are provided.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0007] Preferably, a horizontally arranged slide is provided in the shell, a side push rod is slidably connected in the slide, and a first rack is provided on one side of the side push rod; the shell is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to the pressure rod, and a first gear is fixedly sleeved on the rotating shaft, and the first gear and the first rack are meshed.

[0008] Preferably, a connecting rod rotatably connected to the shell is provided in the movable space, a rocker arm is fixedly connected to the upper end of the connecting rod, a first slide groove is provided at the lower end of the connecting rod, a second slide groove is provided at one end of the side push rod, and sliding shafts are movably provided in the first slide groove and the second slide groove.

[0009] Preferably, a second gear rotatably connected to the housing is further provided in the activity space, a second rack is provided on one side of the upper pressing rod, and the second gear is meshed with the second rack.

[0010] Preferably, the second gear is fixedly connected to a plurality of groups of shift forks, with gaps being left between each group of shift forks, and the upper end of the rocker arm is slidably disposed in the gaps.

[0011] Preferably, the spring is arranged in the movable space, and in an initial state, a connection point between the spring and the upper pressing rod is higher than a connection point between the spring and the housing.

[0012] Preferably, one side of the upper push rod is connected to a first guide block, and one side of the shell is connected to a second guide block. The spring is sleeved on the first guide block and the second guide block. One end of the spring is connected to the upper push rod, and the other end of the spring is connected to the shell.

[0013] Preferably, a limiting block having a limiting function is fixed to the upper push rod, and the limiting block is arranged in the activity space. In an initial state, under the action of a spring, the limiting block is in contact with the housing.

[0014] The present invention also provides a method for using a quick fixing device for pipes buried in buildings, which uses the quick fixing device for pipes buried in buildings, including the following steps:

[0015] S1: Place the housing in the buried pipe groove opened in the wall, then place the threading pipe in the card cavity, and push the housing inward through the threading pipe;

[0016] S2: As the threading pipe is continuously pushed, the upper push rod contacts the buried pipe groove, driving the upper push rod to move toward the housing. The upper push rod drives the second gear to rotate through the second rack. The second gear drives the swing rod to swing through the shift fork. The swing rod drives the side push rod to move to both sides through the connecting rod, and the side push rod drives the push rod to rotate.

[0017] S3: As the threading tube continues to be pushed, when the connection point between the spring and the upper push rod is lower than the connection point between the spring and the shell, the spring pushes the upper push rod to continue moving, so that the side push rod passes through the shell and contacts the buried pipe groove, and the pressure rod continues to rotate to clamp the threading tube.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention is provided with an upper push rod. First, the shell is placed in the buried pipe groove, and then the wire threading tube is placed in the card cavity. The shell can be driven to move into the buried pipe groove through the wire threading tube, thereby driving the upper push rod to move into the shell. The upper push rod can drive the shift fork to rotate through the second gear, and then drive the connecting rod to rotate through the rocker rod. The connecting rod can drive the side push rod to move to both sides. After the side push rod moves out of the shell, the side push rod and the buried pipe groove are in contact, which can realize the relative fixation of the shell. At the same time, the side push rod can drive the pressure rod to rotate, and the pressure rod can realize the relative fixation of the wire threading tube. The operation is convenient, and the wire threading tube can be quickly fixed after being buried in the groove. The fixing effect is good, which effectively simplifies the overall construction process and improves the construction efficiency.

[0020] 2. The present invention is provided with a spring. In the initial state, since the connection point between the spring and the upper pressure rod is higher than the connection point between the spring and the shell, the spring can drive the upper end of the upper pressure rod to pass through the shell, and the side pressure rod is located in the shell. As the upper pressure rod moves into the shell, when the connection point between the spring and the upper pressure rod is lower than the connection point between the spring and the shell, the spring can push the upper pressure rod to continue to move downward, so that the side pressure rod contacts the buried pipe groove, and the pressure rod contacts the threading tube, thereby realizing relative fixation of the shell and the threading tube, and the fixing effect is good, and the spring can provide continuous force.

[0026] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] Reference Attachment Figure 1-2 This embodiment proposes a quick fixing device for buried pipes in buildings, including a shell 2, which has a card cavity 22 for placing a wire conduit 14. The shell 2 also has an activity space 21, and the activity space 21 is connected to the card cavity 22.

[0028] The card cavity 22 is arranged in the middle and lower part of the shell, and the active space 21 is arranged on both sides of the card cavity 22. The card cavity 22 is a closed structure at the top and open at the lower end. The lower opening part of the card cavity 22 is connected to the active space 21. The card cavity 22 is adapted to the threading tube 14. The lower end opening of the card cavity 22 is slightly larger than the diameter of the threading tube 14. The threading tube 14 can be clamped in the card cavity 22 through the opening part below the card cavity 22.

[0029] A pressure rod 1 is rotatably connected in the movable space 21, and the pressure rod 1 is symmetrically arranged on both sides of the card cavity 22. When the pressure rod 1 rotates, the two pressure rods 1 cooperate with each other to achieve the support work of the lower end of the threading tube 14. The pressure rod 1 and the card cavity 22 cooperate with each other to achieve the relative fixation of the threading tube 14.

[0030] An upper push rod 9 arranged in the vertical direction is also slidably connected to the shell 2. The upper end of the upper push rod 9 passes through the shell 2, and the lower end of the upper push rod 9 is arranged in the activity space 21. The upper push rod 9 is connected to the shell 2 through a spring 12. The upper push rod 9 is used to drive the pressure rod 1 to rotate, and the spring 12 is always in a compressed state.

[0031] One side of the upper push rod 9 is connected to a first guide block 19, and one side of the shell 2 is connected to a second guide block 20. The spring 12 is sleeved on the first guide block 19 and the second guide block 20. One end of the spring 12 is rotatably connected to the upper push rod 9, and the other end of the spring 12 is rotatably connected to the shell 2.

[0032] When the upper push rod 9 moves downward, it drives the spring 12 to rotate. At this time, the spring 12 can rotate relative to the housing 2 and the upper push rod 9, thereby changing the direction of the spring 12. The first guide block 19 and the second guide block 20 can guide the spring 12, so that the spring 12 can maintain good linearity, which is beneficial for the subsequent movement of the upper push rod 9 driven by the spring 12.

[0033] The upper push rod 9 is fixed with a limit block that serves as a limit. The limit block is set in the activity space 21. In the initial state, under the action of the spring 12, the limit block and the shell 2 are in contact. Under the action of the limit block, the upper push rod 9 can be prevented from passing through the shell 2 too far.

[0034] The spring 12 is arranged in the active space 21. In the initial state, the connection point between the spring 12 and the upper push rod 9 is higher than the connection point between the spring 12 and the shell 2. Therefore, under the action of the spring 12, the upper end of the upper push rod 9 can be driven to pass through the shell 2, so that the limit block and the shell 2 are in contact, preventing the upper push rod 9 from passing through the shell 2 for too long.

[0035] A horizontal slideway 15 is provided within the housing 2. A side push rod 4 is slidably connected within the slideway 15. A first rack 5 is provided on one side of the side push rod 4. A rotating shaft is rotatably connected to the housing 2. The rotating shaft is fixedly connected to the pressure rod 1. A first gear 3 is fixedly sleeved on the rotating shaft and meshes with the first rack 5. When the side push rod 4 moves, the first rack 5 drives the first gear 3 and the pressure rod 1 to rotate.

[0036] There are openings on both sides of the slide 15, and the side push rod 4 is always slidably set in the slide 15. The slide 15 plays a role of limiting and guiding the side push rod 4. One end of the side push rod 4 can pass through the shell 2, so that the side push rod 4 and the buried pipe groove 13 are in contact, thereby playing a role of relatively fixing the shell 2.

[0037] A connecting rod 6 rotatably connected to the shell 2 is provided in the activity space 21, the upper end of the connecting rod 6 is fixedly connected to the rocker arm 11, the lower end of the connecting rod 6 is provided with a first slide groove 16, and one end of the side push rod 4 is provided with a second slide groove 17, and a sliding shaft 18 is movably provided in the first slide groove 16 and the second slide groove 17.

[0038] The upper end of the connecting rod 6 is rotatably connected to the shell 2, and a first slide groove 16 is provided at the lower end of the connecting rod 6. A second slide groove 17 is provided at the end of the side push rod 4 close to the connecting rod 6. The sliding shaft 18 always moves freely in the first slide groove 16 and the second slide groove 17. Therefore, when the upper end of the connecting rod 6 rotates around the shell 2, the lower end of the connecting rod 6 can drive the side push rod 4 to move, and the first slide groove 16 and the second slide groove 17 play a role in preventing jamming.

[0039] The end of the side push rod 4 away from the connecting rod 6 can be connected to a pressure block through a small spring. A cavity is opened at the end of the side push rod 4 away from the connecting rod 6. The pressure block and the small spring are slidably arranged in the cavity. One end of the small spring is connected to the pressure block, and the other end of the small spring is connected to the side push rod 4. A rubber pad can be provided on one side of the pressure block to increase the friction force, so as to facilitate the relative fixation of the shell 2. In the initial state, under the action of the spring 12, the pressure block and the side push rod 4 are both located in the shell 2.

[0040] When the connecting rod 6 drives the side push rod 4 to contact the buried pipe groove 13, the pressure block can be brought into contact with the buried pipe groove 13 to compress the small spring. The elastic force of the small spring is much smaller than the elastic force of the spring 12. Therefore, the spring 12 can drive the small spring to compress, so that the spring 12 drives the upper push rod 9 to move downward a sufficient distance, so that the pressure rod 1 rotates a sufficient angle to achieve the support work of the threading tube 14, and also makes the side push rod 4 move a sufficient distance out of the shell 2. At this time, the relative fixation of the shell 2 can also be achieved under the action of the small spring.

[0041] A second gear 8 is also provided in the movable space 21 and is rotatably connected to the housing 2. A second rack 10 is provided on one side of the upper push rod 9. The second gear 8 is meshed with the second rack 10. When the upper push rod 9 moves vertically, the second gear 8 can be driven to rotate by the second rack 10.

[0042] The second gear 8 is fixedly connected to a plurality of shift forks 7, with gaps between each set of shift forks 7. The upper end of the rocker arm 11 slides within these gaps. The shift forks 7 are long enough to ensure that the upper end of the rocker arm 11 always slides within the gaps between the forks 7. When the shift forks 7 rotate, they drive the rocker arm 11 to rotate. At this time, the rocker arm 11 can slide freely within the gaps between the forks 7, preventing it from getting stuck.

[0043] The present invention also provides a method for using a quick fixing device for pipes buried in buildings. The method comprises the following steps:

[0044] S1: Place the housing 2 in the buried pipe groove 13 opened in the wall, then place the threading tube 14 in the card cavity 22, and push the housing 2 inward through the threading tube 14;

[0045] S2: As the threading tube 14 is continuously pushed, the upper push rod 9 contacts the buried pipe groove 13, driving the upper push rod 9 to move toward the housing 2. The upper push rod 9 drives the second gear 8 to rotate through the second rack 10. The second gear 8 drives the swing rod 11 to swing through the fork 7. The swing rod 11 drives the side push rod 4 to move to both sides through the connecting rod 6. The side push rod 4 drives the pressure rod 1 to rotate.

[0046] S3: As the threading tube 14 continues to be pushed, when the connection point between the spring 12 and the upper push rod 9 is lower than the connection point between the spring 12 and the shell 2, the spring 12 pushes the upper push rod 9 to continue to move, so that the side push rod 4 passes through the shell 2 and contacts the buried pipe groove 13, and the pressure rod 1 continues to rotate to clamp the threading tube 14.

[0047] In addition, the housing 2 can also be placed on one side of a wall or a corresponding building to achieve rapid fixing of the threading tube 14. Taking a wall as an example, the threading tube 14 is first placed in the clamping cavity 22, and the housing 2 is pushed toward the wall. After the upper push rod 9 contacts the wall, it drives the upper push rod 9 to move toward the housing 2. When the connection point between the spring 12 and the upper push rod 9 is lower than the connection point between the spring 12 and the housing 2, the spring 12 pushes the upper push rod 9 to continue moving, thereby driving the pressure rod 1 and the clamping cavity 22 to cooperate, thereby clamping the threading tube 14. At the same time, the side push rods 4 on both sides extend. By fixing the side push rods 4, the housing 2 can be fixed, thereby achieving rapid fixing of the threading tube 14.

[0048] It should be noted that the shell 2 is first placed in the buried pipe groove 13, and then the wire threading tube 14 is placed in the card cavity 22. The shell 2 can be driven to move into the buried pipe groove 13 through the wire threading tube 14, thereby driving the upper push rod 9 to move into the shell 2. The upper push rod 9 can drive the fork 7 to rotate through the second gear 8, and then drive the connecting rod 6 to rotate through the rocker rod 11. The connecting rod 6 can drive the side push rod 4 to move to both sides. After the side push rod 4 moves out of the shell 2, the side push rod 4 and the buried pipe groove 13 are in contact, which can realize the relative fixation of the shell 2. At the same time, the side push rod 4 can drive the pressure rod 1 to rotate, and the pressure rod 1 can realize the relative fixation of the wire threading tube 14. It is easy to operate, and can realize the rapid fixation of the wire threading tube 14 after it is buried in the groove. The fixing effect is good, which effectively simplifies the overall construction process and improves the construction efficiency.

[0049] In addition, in the initial state, since the connection point between the spring 12 and the upper push rod 9 is higher than the connection point between the spring 12 and the shell 2, the spring 12 can drive the upper end of the upper push rod 9 to pass through the shell 2, and the side push rod 4 is located inside the shell 2. As the upper push rod 9 moves into the shell 2, when the connection point between the spring 12 and the upper push rod 9 is lower than the connection point between the spring 12 and the shell 2, the spring 12 can push the upper push rod 9 to continue to move downward, so that the side push rod 4 and the buried pipe groove 13 are in contact, and the pressure rod 1 and the threading tube 14 are in contact, thereby realizing the relative fixation of the shell 2 and the threading tube 14, and the fixing effect is good, and the spring 12 can provide continuous force.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
