[0041] EP tube 3 Detailed Implementation
[0042] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0043] This utility model provides an anti-tipping EP pipe fixing device, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes a suction cup 1 and a fixing cylinder 2. The bottom of the fixing cylinder 2 is set on the suction cup 1. The fixing device can be attached to the table by the suction cup 1 to prevent it from tipping over. At the same time, the suction cup 1 is provided with a pulling column 11. When the suction cup 1 is in the suction state, the suction cup 1 can be pulled up by pulling the pulling column 11, thereby moving the entire fixing device. It is simple to operate and easy to use.
[0044] like Figure 2 , Figure 3 As shown, the fixed cylinder 2 has a receiving cavity 25 inside, which communicates with the outside through an opening at the top of the fixed cylinder 2. The receiving cavity 25 is used to place the EP tube 3. When placing the EP tube 3, it can enter the receiving cavity 25 through the opening. In addition, the fixed cylinder 2 is equipped with a first support assembly 21 and a second support assembly 22. The first support assembly 21 is located at the bottom of the inside of the fixed cylinder 2, and the second support assembly 22 is arranged above the first support assembly 21. When the EP tube 3 is placed in the receiving cavity 25, the first support assembly 21 supports the bottom of the EP tube 3, and the second support assembly 22 adjustably supports the middle of the EP tube 3. Through the two support assemblies, the EP tube 3 can be stably held in the receiving cavity 25, improving the stability of the device.
[0045] like Figure 2 As shown, the first support assembly 21 includes a left support rod 211, a left connecting rod 212, a right support rod 213, and a right connecting rod 214. One side of the left connecting rod 212 is connected to the inner wall of one side of the fixed cylinder 2, and the other side of the left connecting rod 212 is connected to the left support rod 211. The end of the left support rod 211 is preferably hinged to the left connecting rod 212. One side of the right connecting rod 214 is connected to the inner wall of the other side of the fixed cylinder 2, and the other side of the right connecting rod 214 is connected to the right support rod 213. The end of the right support rod 213 is preferably hinged to the right connecting rod 214. The left support rod 211 and the right support rod 213 are respectively clamped on both sides of the bottom of the EP tube 3, providing auxiliary support for the bottom of the EP tube 3.
[0046] Furthermore, both the left support rod 211 and the right support rod 213 are in contact with the EP tube 3 through a clamping ring 215. The inner side of the clamping ring 215 is an arc-shaped structure that matches the EP tube 3. By setting the clamping ring 215 with an arc-shaped structure, the support contact surface for the EP tube 3 is larger and the firmness is better.
[0047] like Figure 2 , Figure 3 As shown, the second support component 22 includes multiple fixing units 221, which are arranged around the circumference of the EP tube 3. For example, the number of fixing units 221 can be 2, 3, ..., etc., preferably 2. The middle part of the EP tube 3 is clamped and fixed by the multiple fixing units 221, which increases the stability of the EP tube 3 after placement.
[0048] like Figure 3As shown, each of the fixing units 221 includes a threaded rod 2211 and a pressing plate 2212. The fixing cylinder 2 is provided with a threaded hole 23 and a guide groove 24 communicating with the threaded hole 23. The guide groove 24 is connected to the receiving cavity 25. The pressing plate 2212 is arranged in the guide groove 24 and can slide in the guide groove 24. The threaded rod 2211 passes through the threaded hole 23 and can move along the axial direction of the threaded hole 23 by screwing. The inner end of the threaded rod 2211 is connected to the pressing plate 2212. The outer end of the threaded rod 2211 extends to the outside of the fixed cylinder 2. A handle 231 is provided on the outer end of the threaded rod 2211. When the handle 231 is pinched and turned, the extrusion plate 2212 can be driven to move along the guide groove 24 into or out of the fixed cylinder 2. When the extrusion plate 2212 moves along the guide groove 24 into the fixed cylinder 2, the extrusion plate 2212 extrudes the surface of the EP tube 3, which can squeeze the EP tube 3 tightly and thus fix the EP tube 3, increasing the stability of the EP tube 3 after it is placed in the receiving cavity 25.
[0049] It should be noted that the inner surface of the extrusion plate 2212 is made of soft material, which can reduce damage to the EP tube 3.
[0050] This utility model achieves effective fixation of the EP tube 3 by setting a suction cup structure at the bottom and configuring two support components on the fixing cylinder 2, preventing the EP tube 3 from tipping over. The entire structure can be designed into different specifications according to requirements to adapt to different specifications of EP tube 3.
[0051] The working principle of this utility model is as follows:
[0052] In use, first press down the suction cup 1 to fix it on the table, then put the EP tube 3 into the receiving cavity 25. At this time, the bottom of the EP tube 3 is clamped and fixed by the clamping ring 215 on the left support rod 211 and the clamping ring 215 on the right support rod 213. Then, pinch the handle 231 and turn the handle 231. At this time, the threaded rod 2211 moves along the axis of the threaded hole 23 into the fixed cylinder 2. At the same time, the threaded rod 2211 drives the extrusion plate 2212 to slide along the guide groove 24 towards the receiving cavity 25 until the extrusion plate 2212 extrudes the surface of the EP tube 3 and squeezes the EP tube 3 tightly. At this time, the fixation of the EP tube 3 is completed.
[0053] When the EP tube 3 is needed, hold the handle 231 with your hand and turn the handle 231 in the opposite direction. At this time, the threaded rod 2211 moves along the axis of the threaded hole 23 towards the outside of the fixed cylinder 2. At the same time, the threaded rod 2211 drives the extrusion plate 2212 to slide along the guide groove 24 away from the receiving cavity 25. The extrusion plate 2212 leaves the surface of the EP tube 3. At this time, the EP tube 3 can be taken out. If the fixing device is no longer needed, the suction cup 1 can be pulled up by pulling the pull column 11 and the device can be put back in its original position.
