[0032] Please see Figures 1 to 5The present invention provides a conduit fixer for building construction. A conduit fixer for building construction includes a positioning cylinder 10, an inner compression block 20, an outer compression block 30, an elastic element 40, and a detachable snap-fit ​​element 50. The positioning cylinder 10 is installed in a wire groove, and the conduit passes through the positioning cylinder 10. An extension cylinder 11 extending radially outward is provided on one side of the positioning cylinder 10, and a through channel 12 communicating with the positioning cylinder 10 is provided on the extension cylinder 11. The inner compression block 20 is slidably connected in the through channel 12 and is located on the side of the through channel 12 closest to the positioning cylinder 10. The outer extrusion block 30 is used to apply pressure to the outer wall of the conduit; the outer extrusion block 30 is slidably connected in the through channel 12 and is located on the side of the through channel 12 away from the positioning cylinder 10; the outer extrusion block 30 is used to apply pressure to the inner wall of the wire groove; the elastic element 40 is installed in the through channel 12 and is located between the inner extrusion block 20 and the outer extrusion block 30; the detachable snap-fit ​​element 50 is installed on the extension cylinder 11 and is connected to the inner extrusion block 20 and the outer extrusion block 30; the detachable snap-fit ​​element 50 is used to limit the position of the inner extrusion block 20 and the outer extrusion block 30.

[0033] The conduit fixing device for building construction provided by this utility model, compared with the prior art, has a core structure including a positioning cylinder 10, an inner pressing block 20, an outer pressing block 30, an elastic element 40, and a detachable snap-fit ​​element 50. The positioning cylinder 10 serves as the basic load-bearing structure, its main body used to insert the conduit and install it inside the conduit groove, ensuring the conduit extends stably along the groove direction. An extension cylinder 11 on one side and its internal through-channel 12 provide installation space for the inner pressing block 20 and the outer pressing block 30, allowing them to slide radially. The inner pressing block 20 is close to the inner side of the positioning cylinder 10, directly acting on the outer wall of the conduit, while the outer pressing block 30 is located outside the through-channel 12, contacting the inner wall of the groove. The two form an elastic linkage structure through the intermediate elastic element 40. The detachable snap-fit ​​component 50 pre-locks the positions of the inner compression block 20 and the outer compression block 30. When the detachable snap-fit ​​component 50 is removed, the inner compression block 20 and the outer compression block 30 are respectively placed into the conduit and the trough under the action of the elastic component 40.

[0034] The specific operating steps are as follows: First, select the appropriate number of positioning cylinders 10 according to the size of the cable tray and place them in the cable tray reserved in the wall construction, ensuring that the axis of the positioning cylinder 10 is consistent with the direction of the cable tray; then, pass the cable through the positioning cylinder 10 and adjust the position of the cable to the design requirements; next, quickly remove the detachable snap-fit ​​part 50 from the extension cylinder 11, so that the elastic part 40 in the compressed state releases its potential energy and pushes the inner extrusion block 20 and the outer extrusion block 30 to slide to both sides in the through channel 12, so that the inner extrusion block 20 presses against the outer wall of the cable tray and the outer extrusion block 30 presses against the inner wall of the cable tray, thereby clamping and fixing the entire fixing device in the cable tray, and fixing the cable tray to prevent the cable tray from deforming or falling off. In this way, a rigid connection system of "conduit-fixer-trough" is formed by the bidirectional extrusion structure of the inner extrusion block 20 and the outer extrusion block 30. The inner extrusion block 20 adapts to fit the outer diameter of the conduit, and the outer extrusion block 30 is in close extrusion contact with the inner wall of the trough, so that the fixer is fixed in the trough and the conduit is fixed in the trough, preventing the conduit from deforming or falling off, ensuring the good and stable use of the conduit, and not affecting the service life of the conduit.

[0035] Please see Figures 1 to 5 As a specific embodiment of the conduit fixer for building construction provided by this utility model, the extension cylinder 11 is provided with two connecting holes 13 corresponding to the inner extrusion block 20 and the outer extrusion block 30. Both the inner extrusion block 20 and the outer extrusion block 30 are provided with mounting holes 21 arranged coaxially with the corresponding connecting holes 13. The detachable snap-fit ​​component 50 is provided with two positioning shafts 51 that pass through the connecting holes 13 and the mounting holes 21 respectively. When assembling the fixer, the connecting holes 13 of the extension cylinder 11 are coaxially arranged with the mounting holes 21 of the inner extrusion block 20 and the outer extrusion block 30, and the positioning shafts 51 of the detachable snap-fit ​​component 50 pass through them, achieving a rigid connection between the three. After the positioning shafts 51 are inserted, they can lock the positions of the inner extrusion block 20 and the outer extrusion block 30 when they are not in operation. In use, the two positioning shafts 51 are directly pulled out from the connecting holes 13 and the mounting holes 21. Under the action of the elastic force of the elastic element 40, the inner extrusion block 20 is pushed to squeeze the conduit, and the outer extrusion block 30 is pushed to squeeze the inner wall of the conduit groove. This method features a simple and compact structure, convenient coaxial positioning during installation, and a secure and reliable through-connection of the positioning shaft 51, which effectively prevents the inner extrusion block 20 and the outer extrusion block 30 from sliding when not in use.

[0036] Please see Figure 1 , Figure 2 and Figure 5As a specific embodiment of the conduit fixing device for building construction provided by this utility model, the detachable snap-fit ​​component 50 also includes a middle crossbar 52 for connecting the ends of the two positioning shafts 51 and a handle 53 installed on the middle crossbar 52. That is, the detachable snap-fit ​​component 50 connects the ends of the two positioning shafts 51 through the middle crossbar 52, so that the two positioning shafts 51 form a rigid integral structure. The handle 53 is installed in the middle of the crossbar for easy force application. After the positioning shaft 51 passes through the connecting hole 13 of the extension cylinder 11 and the mounting holes 21 on the inner extrusion block 20 and the outer extrusion block 30, pushing and pulling the handle 53 can synchronously drive the positioning shaft 51 to move, realizing the quick locking or unlocking of the inner extrusion block 20 and the outer extrusion block 30. The handle 53 reduces the difficulty of operation, and the construction personnel can easily adjust the position of the inner extrusion block 20 and the outer extrusion block 30 with one hand, improving the installation efficiency; the middle crossbar 52 ensures that the two positioning shafts 51 are subjected to uniform force, avoids the problem of fixing failure caused by unilateral offset, and enhances the stability and reliability of the connection structure.

[0037] Please see Figure 1 , Figure 2 and Figure 5 As a specific embodiment of the conduit fixing device for building construction provided by this utility model, the two positioning shafts 51, the intermediate crossbar 52, and the handle 53 are integrally formed. The two positioning shafts 51, the intermediate crossbar 52, and the handle 53 adopt an integral molding design, forming a rigid, seamless whole structure through injection molding or die casting. After the positioning shaft 51 passes through the hole in the extension cylinder 11 and the inner extrusion block 20 or the outer extrusion block 30, the handle 53 can directly drive the entire assembly to move synchronously, realizing the locking and releasing of the inner extrusion block 20 and the outer extrusion block 30. The integral molding structure eliminates gaps between components, resulting in higher structural strength and preventing the positioning shaft 51 from loosening and falling off.

[0038] Please see Figure 2 and Figure 5 As a specific embodiment of the conduit fixing device for building construction provided by this utility model, the end of the positioning shaft 51 away from the intermediate crossbar 52 is provided with a positioning boss 54, and the outer diameter of the positioning boss 54 is larger than the diameter of the connecting hole 13; the side of the positioning boss 54 near the extension cylinder 11 is an inclined guide surface 55. The positioning boss 54 at the end of the positioning shaft 51 away from the intermediate crossbar 52, whose outer diameter is larger than the diameter of the connecting hole 13, can be locked onto the outside of the extension cylinder 11 to prevent the positioning shaft 51 from axially falling off; the inclined guide surface 55 on the side of the positioning boss 54 near the extension cylinder 11 can guide the positioning shaft 51 to smoothly disengage from the connecting hole 13 and the mounting hole 21 during installation. The positioning boss 54 cooperates with the inclined surface so that after the positioning shaft 51 passes through the connecting hole 13, it is axially locked by the positioning boss 54, and at the same time, the guiding effect of the inclined surface reduces the operating resistance during construction.

[0039] Please see Figure 1 , Figure 2 and Figure 4 As a specific embodiment of the conduit fixer for building construction provided by this utility model, the end of the inner extrusion block 20 near the positioning cylinder 10 is an arc-shaped surface 22 adapted to the outer wall of the conduit, and the arc-shaped surface 22 is provided with a plurality of protrusions 23 for increasing friction. The end of the inner extrusion block 20 near the positioning cylinder 10 is designed as an arc-shaped surface 22 adapted to the outer wall of the conduit. This curved surface can closely fit the circular contour of the conduit, so that the extrusion stress is evenly distributed in the circumference of the conduit, avoiding localized stress concentration that could lead to conduit deformation; the plurality of protrusions 23 provided on the arc-shaped surface 22, by increasing the contact friction coefficient with the outer wall of the conduit, effectively prevent the conduit from sliding axially or rotating circumferentially in the fixed state. The contoured design of the curved surface 22 improves the compatibility between the fixture and the conduit, making it compatible with the installation of conduits of different diameters. The uniform compression contact reduces the risk of deformation of the conduit caused by rigid clamping. The friction-enhancing structure of the protrusion 23 further strengthens the fixing reliability, ensuring stable fixing of the conduit even when the wall vibrates or the force changes.

[0040] Please see Figure 1 , Figure 2 and Figure 4 As a specific embodiment of the conduit fixer for building construction provided by this utility model, the outer extrusion block 30 has a straight boss 31 or a cross boss at one end away from the positioning cylinder 10 for contacting the inner wall of the conduit groove. The straight boss 31 or cross boss at the end of the outer extrusion block 30 is used for contacting and extruding against the inner wall of the conduit groove. The straight boss 31 or cross boss can be embedded into the inner wall of the conduit groove, increasing the contact friction and enhancing the interlocking and fixing effect between the outer extrusion block 30 and the conduit groove. This effectively prevents the fixer from falling off and improves the fixing stability and applicability.

[0041] Please see Figure 1 , Figure 2 and Figure 4 In one specific embodiment of the conduit fixation device for building construction provided by this utility model, the elastic element 40 is a spring, and the inner compression block 20 and the outer compression block 30 are provided with receiving grooves 32 at their opposing ends for embedding the two ends of the spring. The elastic force generated when the spring is compressed pushes the inner compression block 20 and the outer compression block 30 to press against the conduit and the groove respectively. The receiving grooves 32 can limit the radial displacement of the spring and prevent it from slipping or tilting during expansion and contraction. With this structure, the spring provides a continuous and stable elastic compression force to meet the buffering needs of slight deformation of the wall; the receiving grooves 32 ensure accurate spring installation and positioning, enhance structural reliability, and prevent the fixation force from weakening due to spring displacement.

[0042] Please see Figures 1 to 3As a specific embodiment of the conduit fixer for building construction provided by this utility model, the positioning cylinder 10 and the extension cylinder 11 are integrally formed by injection molding or die casting, forming a rigid, seamless whole structure. The integral molding design eliminates weak points at component connections, ensuring the perpendicularity of their axes and structural stability. Furthermore, the high coaxiality of the entire positioning cylinder 10 and extension cylinder 11 facilitates the sliding guidance of the inner extrusion block 20 and the outer extrusion block 30, enhancing the reliability and durability of the fixer after installation.

[0043] Please see Figure 1 and Figure 2 As a specific embodiment of the conduit fixing device for building construction provided by this utility model, there are two extension cylinders 11, symmetrically arranged on both sides of the positioning cylinder 10; each extension cylinder 11 is provided with an inner pressing block 20, an elastic element 40, and an outer pressing block 30; there are two detachable snap-fit ​​pieces 50, which are respectively installed on the two extension cylinders 11. Two extension cylinders 11 are symmetrically arranged on both sides of the positioning cylinder 10, and each extension cylinder 11 is provided with an inner pressing block 20, an elastic element 40, and an outer pressing block 30. The two sets of detachable snap-fit ​​pieces 50 respectively lock the inner pressing block 20 and the outer pressing block 30 in the two extension cylinders 11. The symmetrically distributed extension cylinders 11 can simultaneously press the outer wall of the conduit through the inner pressing block 20, and the outer pressing block 30 presses against the inner wall of the conduit groove. The elastic element 40 provides bidirectional continuous elastic force, forming a circumferentially balanced clamping system. The detachable snap-fit ​​pieces 50 pre-fix the positions of the inner pressing block 20 and the outer pressing block 30 to prepare for the subsequent pressing action. In this way, the double-sided symmetrical structure ensures that the conduit is subjected to uniform stress, avoiding deformation or displacement caused by unilateral compression, and effectively resisting the stress generated by wall vibration or settlement; the double extension tube 11 design can be adapted to various conduit cross sections such as rectangular and trapezoidal, and the bidirectional buffering effect of the elastic element 40 enhances the structure's adaptability to environmental deformation.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
