[0002] In building construction, drainage risers come in various sizes to suit different installation locations and drainage needs. Generally, drainage risers are fixed to the wall mounting brackets using clamps. Different inner diameter clamps are required for fixing drainage risers of different diameters, which means that clamps of various inner diameters need to be pre-processed, resulting in high production costs. Furthermore, during installation, workers need to find the matching clamps according to the different sizes of drainage risers, resulting in low installation efficiency. Utility Model Content

[0003] The main purpose of this utility model is to propose a riser support, which aims to solve the problems of high production cost and low installation efficiency when existing riser supports need to fix drainage risers of various diameters.

[0004] To achieve the above objectives, this utility model proposes a riser support, including a mounting base, a connecting arm, and an elastic clamp for surrounding and securing the drainage riser. The mounting base has an installation structure for wall mounting and fixing. The connecting arm is connected to the mounting base. The connecting arm is provided with a plurality of mounting holes for detachable connection of the two ends of the elastic clamp. The plurality of mounting holes are spaced apart in the opening or closing direction of the elastic clamp, so that the distance between the two ends of the elastic clamp can be adjusted to adjust the inner diameter of the elastic clamp.

[0005] According to some embodiments of the present invention, the connecting support arm is further provided with a first guide groove, the plurality of mounting holes are connected through the first guide groove, and both ends of the elastic clamp are movably disposed on the first guide groove.

[0006] According to some embodiments of the present invention, the opening or closing direction of the elastic clamp is consistent with the length direction of the connecting arm. The first guide groove includes a plurality of first groove segments and a second groove segment connecting the plurality of first groove segments. The mounting hole is connected to the second groove segment through the first groove segment. The second groove segment extends along the length direction of the connecting arm. The plurality of first groove segments are spaced apart along the length direction of the connecting arm and extend along its width direction.

[0007] According to some embodiments of the present invention, a rubber protective sleeve is fitted on the elastic clamp, and the rubber protective sleeve has an abutment wall that can abut against the drainage riser.

[0008] According to some embodiments of the present invention, the mounting base includes a fixed plate and a connector connected to each other. The fixed plate has the mounting structure on the side facing away from the connector, and the connector is sleeved on the connecting support arm.

[0009] According to some embodiments of the present invention, the connecting arm is telescopically disposed within the connecting member, and the connecting arm is provided with a plurality of first connecting holes spaced apart along its length direction. The connecting member is provided with corresponding second connecting holes so that bolts can pass through the second connecting holes and be fixedly connected to the corresponding first connecting holes.

[0010] According to some embodiments of the present invention, at least two second connecting holes are provided so that two bolts pass through the two connecting holes respectively and are fixedly connected to the corresponding two first connecting holes.

[0011] According to some embodiments of the present invention, the fixing plate has two fixing hole assemblies, which are respectively located on both sides of the connection between the connector and the fixing plate. The fixing hole assembly includes a plurality of fixing holes spaced apart in the horizontal direction, so that a bolt can pass through one of the fixing holes and be fixedly connected to the wall.

[0012] According to some embodiments of the present invention, the fixing hole assembly further includes a second guide groove for the bolt to be moved, the second guide groove extends in the horizontal direction, and the plurality of fixing holes are connected through the second guide groove.

[0013] According to some embodiments of the present invention, a flexible support arm cap is provided at the end of the connecting support arm away from the mounting base.

[0014] This utility model has at least the following beneficial effects:

[0015] In this invention, the mounting base is first fixed to the wall, and the connecting bracket is connected to the mounting base. When a smaller diameter drainage riser needs to be fixed, the two ends of the elastic clamp are driven closer together, so that the inner diameter of the elastic clamp gradually decreases until the contact area between the inner wall of the elastic clamp and the outer wall of the drainage riser meets the requirements. At this time, the two ends of the elastic clamp are connected to the two corresponding mounting holes to complete the fixing of the drainage riser. When a larger diameter drainage riser needs to be fixed, the two ends of the elastic clamp are driven further apart, so that the inner diameter of the elastic clamp gradually increases until the contact area between the inner wall of the elastic clamp and the outer wall of the drainage riser meets the requirements. At this time, the two ends of the elastic clamp are connected to the two corresponding mounting holes to complete the fixing of the drainage riser. This invention utilizes multiple mounting holes on the connecting bracket. After adjusting the two ends of the elastic clamp to a suitable distance, the two ends of the elastic clamp are fixed through the mounting holes, preventing the elastic clamp from rebounding. This allows the elastic clamp on the riser support to adapt to drainage risers of various diameters. Therefore, it eliminates the need to pre-process clamps of various inner diameters, reducing production costs. Furthermore, it eliminates the need to find clamps that match the diameter of the drainage riser during installation, improving installation efficiency. Attached Figure Description

[0027] This utility model provides a riser support. Figures 1 to 5 This is a specific embodiment of a riser support provided by the present utility model.

[0028] like Figure 1 and Figure 2As shown, this utility model embodiment provides a riser support 100, including a mounting base 1, a connecting arm 2, and an elastic clamp 3 for surrounding and securing a drainage riser 200. The mounting base 1 has an installation structure for wall mounting and fixing. The connecting arm 2 is connected to the mounting base 1. The connecting arm 2 is provided with a plurality of mounting holes 21 for detachable connection of the two ends of the elastic clamp 3. The plurality of mounting holes 21 are spaced apart in the opening or closing direction of the elastic clamp 3 so that the distance between the two ends of the elastic clamp 3 can be adjusted to adjust the inner diameter of the elastic clamp 3.

[0029] In this invention, the mounting base 1 is first fixed to the wall, and the connecting arm 2 is connected to the mounting base 1. When it is necessary to fix a drainage riser 200 with a smaller diameter, the two ends of the elastic clamp 3 are driven to move closer to each other, so that the inner diameter of the elastic clamp 3 gradually decreases until the contact area between the inner side wall of the elastic clamp 3 and the outer side wall of the drainage riser 200 meets the requirements. At this time, the two ends of the elastic clamp 3 are connected to the two corresponding mounting holes 21 respectively to complete the fixation of the drainage riser 200. When it is necessary to fix a drainage riser 200 with a larger diameter, the two ends of the elastic clamp 3 are driven to move further apart, so that the inner diameter of the elastic clamp 3 gradually increases until the contact area between the inner side wall of the elastic clamp 3 and the outer side wall of the drainage riser 200 meets the requirements. At this time, the two ends of the elastic clamp 3 are connected to the two corresponding mounting holes 21 respectively to complete the fixation of the drainage riser 200. This invention utilizes multiple mounting holes 21 on the connecting support arm 2 to fix the two ends of the elastic clamp 3 through the mounting holes 21 after adjusting the two ends to a suitable distance, thus preventing the elastic clamp 3 from rebounding. This allows the elastic clamp 3 on the riser support 100 to adapt to drainage risers 200 of various diameters. Therefore, it is not necessary to pre-process clamps of various inner diameters, reducing production costs. Furthermore, during installation, it is not necessary to find clamps that match the diameter of the drainage riser 200, improving the efficiency of installation.

[0030] Specifically, such as Figure 5 As shown, the elastic clamp 3 includes a flat steel and two threaded rods connected to both ends of the flat steel. The inner side wall of the bent flat steel can fit against the outer side wall of the drainage riser 200, increasing the contact area and thus increasing the friction, making the fixation more secure. The threaded rod is provided with external threads, and after the threaded rod passes through the mounting hole 21, it can be fixed by connecting with a nut.

[0031] It should be noted that in some embodiments, such as Figure 1As shown, the end of the connecting arm 2 furthest from the mounting base 1 is provided with a flexible arm cap 5. Since the connecting arm 2 is generally made of metal, its end is relatively sharp. By providing the flexible arm cap 5 at the end, the end of the connecting arm 2 can be prevented from injuring passing personnel.

[0032] Preferably, in some embodiments, such as Figure 2 As shown, the connecting arm 2 is also provided with a first guide groove 22, and the plurality of mounting holes 21 are connected through the first guide groove 22. Both ends of the elastic clamp 3 are movably mounted on the first guide groove 22. With this configuration, the construction personnel do not need to first drive the two ends of the elastic clamp 3 to adjust the distance between the two ends, and after adjusting to a suitable distance, keep the elastic clamp 3 in its current state before connecting the two ends of the elastic clamp 3 to the two mounting holes 21. They only need to insert the two ends of the elastic clamp 3 into the first guide groove 22, and then directly drive the two ends to move to the corresponding positions of the two mounting holes 21 to complete the connection. This is more labor-saving and has higher installation efficiency.

[0033] Specifically, in some embodiments, such as Figure 2 As shown, the opening or closing direction of the elastic clamp 3 is consistent with the length direction of the connecting arm 2. The first guide groove 22 includes multiple first groove segments 221 and a second groove segment 222 connecting the multiple first groove segments 221. The mounting hole 21 communicates with the second groove segment 222 through the first groove segment 221. The second groove segment 222 extends along the length direction of the connecting arm 2. The multiple first groove segments 221 are spaced apart along the length direction of the connecting arm 2 and extend along its width direction. With this arrangement, the second groove segment 222 serves to adjust the distance between the two ends of the elastic clamp 3, while the groove wall of the first groove segment 221 can act as a limit to prevent the elastic clamp 3 from rebounding.

[0034] Since the elastic clamp 3 is generally made of metal, while the drainage riser 200 is generally made of plastic, the friction between the two materials is small. This results in a poor actual fixing effect even when the elastic clamp 3 clamps the drainage riser 200. Therefore, in some embodiments, such as... Figure 1 and Figure 5As shown, a rubber protective sleeve 4 is fitted onto the elastic clamp 3. The rubber protective sleeve 4 has an abutment wall 41 that can abut against the drainage riser 200. With this configuration, the rubber protective sleeve 4, being made of rubber, generates significant friction with the plastic drainage riser 200. By fitting the rubber protective sleeve 4 onto the elastic clamp 3, the abutment wall 41 of the rubber protective sleeve 4 abuts against the outer wall of the drainage riser 200, making the drainage riser 200 more securely fixed. Simultaneously, the rubber protective sleeve 4 also prevents damage to the outer wall of the drainage riser 200 caused by the metal elastic clamp 3 when clamping it.

[0035] The specific structure of the mounting base 1 is not limited, as long as it ensures that the mounting base 1 can be fixed to the wall. For example, in some embodiments, such as... Figure 1 As shown, the mounting base 1 includes a fixed plate 11 and a connector 12 connected to each other. The fixed plate 11 has the mounting structure on the side facing away from the connector 12, and the connector 12 is sleeved on the connecting support arm 2. This arrangement allows the connector 12 to be fixedly connected to the connecting support arm 2 by sleeve, increasing the contact area between the connector 12 and the connecting support arm 2 and preventing the connection between the connector 12 and the connecting support arm 2 from breaking due to large shear forces.

[0036] Furthermore, in some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the connecting arm 2 is telescopically mounted within the connector 12. The connecting arm 2 has multiple first connecting holes 23 spaced apart along its length. The connector 12 has corresponding second connecting holes 121 for bolts to pass through and be fixedly connected to the corresponding first connecting holes 23. This configuration allows for adjustment of the distance between the elastic clamp 3 and the wall through the telescopic extension of the connecting arm 2, thus adapting to different installation positions of the drainage riser 200. After the connecting arm 2 is telescopically adjusted to a suitable position, bolts pass through the second connecting holes 121 and are fixedly connected to the corresponding first connecting holes 23, thereby achieving the connection and fixation between the connecting arm 2 and the connector 12.

[0037] Because the bolt will be subjected to a large shear force converted from the weight of the connecting bracket 2 and the elastic clamp 3, it may deform after prolonged use. Therefore, in some embodiments, such as Figure 1 and Figure 4As shown, at least two second connecting holes 121 are provided, allowing two bolts to pass through two of the connecting holes respectively and be fixedly connected to the corresponding two first connecting holes 23. By providing multiple second connecting holes 121, the connection between the connecting arm 2 and the connecting member 12 is made more stable, and the shearing force can also be distributed by increasing the number of bolts.

[0038] Because construction workers may encounter situations where the drilling location is exactly at the steel reinforcement skeleton inside the wall when drilling according to the design points of the wall and the riser support 100, the drilling position needs to be adjusted. Therefore, in some embodiments, such as Figure 1 and Figure 3 As shown, the fixing plate 11 has two fixing hole assemblies 111, which are located on both sides of the connection between the connector 12 and the fixing plate 11. Each fixing hole assembly 111 includes multiple fixing holes 1111 spaced apart in the horizontal direction, allowing bolts to pass through one of the fixing holes 1111 and be fixedly connected to the wall. This arrangement allows for several advantages. First, when one fixing hole 1111 is located at the steel reinforcement frame of the wall, the construction worker can choose to drill holes at adjacent fixing holes 1111, ensuring that the bolts do not interfere with the steel reinforcement frame inside the wall when passing through the fixing holes 1111. Second, by adjusting the position of the fixing plate 11 of the mounting base 1 without changing the drilling point, the position of the riser bracket 100 can be adjusted to accommodate different installation positions of the drainage riser 200.

[0039] Furthermore, in some embodiments, such as Figure 1 and Figure 3 As shown, the fixing hole assembly 111 further includes a second guide groove 1112 for bolt movement. The second guide groove 1112 extends horizontally, and the plurality of fixing holes 1111 are connected through the second guide groove 1112. With this configuration, the bolt can first pass through the fixing hole assembly 111 without being locked to the wall. Then, the construction worker drives the mounting base 1 to move, causing the bolt to move relative to the fixing plate 11 on the mounting base 1 until the bolt enters the desired fixing hole 1111 position. After the horizontal position adjustment of the riser bracket 100 is completed, the bolt is then locked to the wall.
