Description

Technical Field

[0001] This utility model relates to the field of profile tube manufacturing technology, and in particular to a profile tube support device. Background Technology

[0002] When spraying the profile tube, it needs to be fixed. One way to fix the profile tube is to clamp it on the outer surface of both ends. However, when fixing it on the outer surface, the spray will leave marks in the clamping area, so the marked parts are usually cut off after spraying, resulting in waste. Another way is to insert fixing blocks into both ends of the profile tube for fixation. However, the above fixing method is more convenient for fixing regular tubes, but it is more difficult to fix irregular tubes, resulting in poor fixing effect. Utility Model Content

[0003] The purpose of this utility model is to provide a profile tube support device to improve the fixing effect and reduce material waste.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a profile tube support device, which includes two sets of expansion components 1. Each set of expansion components 1 includes a first support plate 11. A first bladder 13 is provided on one side of the two first support plates 11 facing each other. A first filling hole 12 is provided on the first support plate 11. The first bladder 13 is connected to a fluid replenishment device through the first filling hole 12. The first support plates 11 of the two sets of expansion components 1 can move closer to or further away from each other.

[0031] When fixing the profile tube, it is only necessary to move the two first support plates 11 closer together and insert the two first bladders 13 into both ends of the profile tube. Then, gas or liquid is filled into the first bladders 13 to make them expand. The expanded first bladders 13 can adapt to different inner surfaces of the profile tube and can be fixed by the friction between the first bladders 13 and the profile tube, thus making the fixation more stable. After the spraying is completed, the liquid or gas in the first bladders 13 can be released, and then the two first support plates 11 can be moved away from each other. There is no need to cut off both ends of the profile tube, avoiding material waste.

[0032] like Figure 2 As shown, in some embodiments, the expansion tube further includes a first conduit 14. One end of the first conduit 14 is fixed on the first support plate 11, and the end of the first conduit 14 covers the first filling hole 12, so that the first filling hole 12 is located inside the first conduit 14. The other end of the first conduit 14 is connected to the first bladder 13. When the first bladder 13 is inserted into the profile tube, the profile tube can be supported by the first conduit 14, which further facilitates the fixing of the profile tube.

[0033] like Figure 2As shown, in some embodiments, the expansion assembly 1 further includes a base 119, on which a first driving member 15 is fixed. A first support plate 11 is disposed at the output end of the first driving member 15, thereby driving the first support plate 11 to move through the first driving member 15, thus enabling the two first bladders 13 to move closer or further apart. Specifically, each first support plate 11 is provided with at least one first driving member 15. To ensure stability, in the current embodiment, each first support plate 11 is provided with two first driving members 15. A first elastic member 16 is connected between the output end of the first driving member 15 and the first support plate 11, thereby buffering when the first support plate 11 contacts the profile tube, reducing hard contact between the first support plate 11 and the profile tube, and reducing unnecessary damage. More specifically, the first driving member 15 is an electric push rod, and the push rod end of the electric push rod is provided with a sliding groove 116 arranged along the push rod axis. A guide rod 117 is connected to the first support plate 11. The first elastic member 16 is a compression spring, which is sleeved on the guide rod 117 and abuts against the output end between the first support plate 11 and the first driving member 15. The guide rod 117 slides in the sliding groove 116, thereby guiding the first elastic member 16 and reducing the stability of the first elastic member 16 during the extrusion process, thus ensuring the stability of the movement of the first support plate 11.

[0034] In some embodiments, the first capsule 13 is an annular capsule, and the corresponding first conduit 14 is an annular tube. The annular capsule can increase the contact area with the profile tube, thereby improving stability.

[0035] like Figure 2 As shown, in some embodiments, the expansion assembly 1 further includes a second support plate 17, on which a second bladder 19 is disposed, and a second filling hole 18 is disposed on the second support plate 17. The second bladder 19 is connected to a fluid replenishment device through the second filling hole 18, thereby allowing fluid to be supplied to the second bladder 19 to inflate it. The second support plate 17 is movable relative to the first support plate 11, thereby allowing the second bladder 19 to intersect with the first bladder 13, so that the second bladder 19 abuts against the first bladder 13 radially along the profile tube, increasing the contact pressure between the first bladder 13 and the profile tube, and further improving the fixation stability.

[0036] In the current embodiment, when the first bladder 13 is an annular bladder, the first bladder 13 is sleeved on the outside of the second bladder 19. In the initial state, the second bladder 19 extends out of the first bladder 13. After the first bladder 13 and the second bladder 19 are filled with fluid, the second support plate 17 is moved so that the second bladder 19 enters the inner ring of the first bladder 13, thereby squeezing the first bladder 13 and increasing the contact pressure between the first bladder 13 and the inner wall of the profile tube.

[0037] like Figure 2As shown, in some embodiments, the expansion assembly 1 further includes a second conduit 110. One end of the second conduit 110 is fixed to the second support plate 17, with the second filling hole 18 located inside the second conduit 110. The other end of the second conduit 110 passes through the first support plate 11 and is connected to the second bladder 19. The second conduit 110 can move relative to the first support plate 11 under the action of the second support plate 17. The second conduit 110 can ensure smooth fluid flow to the second bladder 19 when the first bladder 13 expands, reducing the impact of the expansion of the first bladder 13 on the fluid flow to the second bladder 19.

[0038] Since the first capsule 13 is in a ring-shaped state, the second catheter 110 is inserted into the inner ring of the first capsule 13.

[0039] like Figure 2 As shown, in some embodiments, a ring seat 111 is fixed inside the second conduit 110, and a support rod 112 is inserted into the ring seat 111. The first end of the support rod 112 extends into the second bladder 19, thereby supporting the second bladder 19 and reducing the possibility that the second bladder 19 is in a bent state when it is not filled with fluid, thus avoiding affecting the filling effect.

[0040] like Figure 2 As shown, the first end of the support rod 112 is provided with a support head 113. The support head 113 can be, but is not limited to, a circular block. Using the support head 113 to support the second bladder 19 can increase the contact area and reduce the risk of the first end of the support rod 112 damaging the second bladder 19. In addition, the second end of the support rod 112 is provided with a blocking block 114. The blocking block 114 and the support head 113 are located on both sides of the ring seat 111, and the support rod 112 can slide relative to the ring seat 111. A second elastic element 115 is provided between the blocking block 114 and the ring seat 111 or between the support head 113 and the ring seat 111. So when fluid enters the second bladder 19, the fluid acts on the support head 113 and drives the support rod 112 to move relative to the ring seat 111. At this time, the second elastic element 115 accumulates potential energy, so that it can drive the support rod 112 to return to its original position after the force is lost. Exemplarily, the second elastic element 115 is also a compression spring, which is sleeved on the support rod 112. Furthermore, the presence of the second elastic element 115 can also buffer the force of the support head 113 against the second bladder 19, preventing excessive impact.

[0041] like Figure 2 As shown, in some embodiments, the expansion assembly 1 further includes a third drive member 118, which may be disposed on the base 119. Each second support plate 17 corresponds to at least one third drive member 118. The second support plate 17 is connected to the output end of the third drive member 118, thereby driving the second support plate 17 to move via the third drive member 118. Exemplarily, the third drive member 118 may be, but is not limited to, an electric push rod.

[0042] like Figure 1 As shown, in some embodiments, the profile tube support device further includes a mounting base 4, on which a slide rail 3 and a rack 6 are provided. The rack 6 and the slide rail 3 extend in the same direction. The base 119 of the two expansion components 1 slides on the slide rail 3. A second driving member 2 is provided on the base 119. The output end of the second driving member 2 is connected to a drive gear 5, which meshes with the rack 6. Thus, the two expansion components 1 are driven to move closer or further apart through the second driving member 2. In the current embodiment, the two expansion components 1 are respectively associated with the second driving member 2. In use, the positions of the two sets of expansion components 1 can be roughly adjusted by first driving the second driving member 2, and then the positions can be precisely adjusted by the first driving member 15 and the third driving member 118.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
