Description

Technical Field

[0001] This utility model relates to the field of machinery, specifically to a support frame. Background Technology

[0002] Due to manufacturing process issues, the annular pipes produced by pipe bending machines are rarely perfectly round; they almost always have process defects that are uncontrollable. This results in each annular pipe being slightly different, leading to situations where the connection with the base is not tight in some areas or cannot be made at all. Utility Model Content

[0003] The purpose of this utility model is to provide a bracket for installing annular bends to solve the above-mentioned technical problems.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution:

[0005] A bracket for mounting annular bends includes a support rod, characterized in that a first groove is formed on the side wall of the support rod, a clamping block is inserted into the first groove, the clamping block is provided with a notch, and the orientation of the notch is the same as the orientation of the first groove.

[0006] The clamping block is provided with a clamping block on the side facing away from the notch, which drives the clamping block to slide along the first groove.

[0007] In use, the clamping block drives the clamping block to move outward along the first groove, thereby pushing out the clamping block and engaging the smaller diameter part of the annular bend. The clamping block moves inward along the first groove, thereby reducing the extension length of the clamping block and engaging the larger diameter part of the annular bend.

[0008] As a preferred embodiment, the support rod is further provided with a second groove, which is located in the vertical direction with its opening facing upwards, while the first groove is located in the horizontal direction.

[0009] The clamping block is located in the second groove, and a first bolt mechanism is connected to the clamping block to drive the clamping block to slide up and down along the second groove.

[0010] The second groove and the first groove are connected, the clamping block and the pressing block are pressed together at the connection point, and at least one of the surfaces of the clamping block and the pressing block near the connection point is an inclined surface.

[0011] Preferably, a first bolt hole is formed on the bottom of the second groove, and the orientation of the first bolt hole is the same as the orientation of the second groove;

[0012] The clamping block has a first through hole at a position corresponding to the first bolt hole, and the first bolt passes through the first through hole and is screwed into the first bolt hole;

[0013] The first bolt, the first bolt hole, and the through hole constitute the first bolt mechanism. This allows the position of the clamping block to be adjusted using the limiting first bolt, and after adjustment, the position of the clamping block can be fixed, thereby fixing the position of the clamping block.

[0014] Preferably, a spring is fitted onto the first bolt, with one end of the spring abutting against the clamping block and the other end abutting against the bottom of the second groove. Thus, after the first bolt is removed, the spring force causes the clamping block to move upwards and return to its original position.

[0015] As another preferred embodiment, the clamping block is located in the first groove, the clamping block and the clamping block are in close contact, and a second bolt mechanism is connected to the clamping block to drive the clamping block to slide along the first groove.

[0016] Preferably, the support rod has a second bolt hole that communicates with the first groove. The second bolt passes through the second bolt hole and is fixedly connected to the clamping block. This allows the position of the clamping block to be adjusted using the limiting second bolt, and after adjustment, the position of the clamping block can be fixed, thereby fixing the position of the clamping block.

[0017] Preferably, the clamping blocks are symmetrical vertically, and the diameter of the notch gradually increases from the inside to the outside. This structure makes it easier for the notch of the clamping block to be snapped onto the annular pipe fitting. In addition, it has the following unexpected technical effects: on the one hand, it allows the notch of the clamping block to open and close relatively uniformly, thereby solving the snapping problem when the diameter of the annular pipe fitting varies in different places by utilizing the opening and closing of the clamping block; on the other hand, the clamping blocks can be installed vertically interchangeably, thereby reducing the requirements for the installation direction during installation.

[0018] Preferably, the notch is covered with a functional layer. This functional layer improves the strength of the notch and the stability of the connection between the notch and the annular pipe.

[0019] Preferably, there are multiple support rods arranged in a ring structure, with the first groove of each support rod facing the center of the ring structure. This increases the stability of the annular pipe by utilizing multiple support rods.

[0020] Preferably, the bracket for mounting the annular bend further includes a support plate connected below the support rod, wherein the cross-sectional area of ​​the support plate is larger than that of the support rod. This increases the contact area between the bracket and the external base, thereby improving the support strength and stability of the bracket. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The bracket for installing annular bend pipe mainly includes a support rod 1, a clamping block 2, and a pressing block 3. A first groove is opened on the side wall of the support rod 1, and the clamping block 2 is inserted into the first groove. The clamping block 2 has a notch, and the orientation of the notch is the same as that of the first groove. A pressing block 3 is provided on the side of the clamping block 2 facing away from the notch, which drives the clamping block 2 to slide along the first groove.

[0027] In use, the clamping block 3 drives the clamping block 2 to move outward along the first groove, thereby pushing out the clamping block 2 and engaging the smaller diameter part of the annular bend. The clamping block 2 moves inward along the first groove, thereby reducing the extension length of the clamping block 2 and engaging the larger diameter part of the annular bend.

[0028] Specific embodiment 1, such as Figure 1 As shown

[0029] The support rod 1 also has a second groove, which is located in the vertical direction with the opening facing upwards, while the first groove is located in the horizontal direction. Figure 1 The first groove faces left, and the second groove faces upward. The second groove and the first groove are connected. The clamping block 2 is located in the first groove, and the pressing block 3 is located in the second groove. The clamping block 2 and the pressing block 3 are pressed together at the connection point. The lower left side of the pressing block 3 is pressed against the upper right side of the clamping block 2, and at least one of the lower left side of the pressing block 3 and the upper right side of the clamping block 2 is a slope. Figure 1In this structure, both sides are inclined surfaces with the same degree of inclination. Specifically, the side of clamping block 2 away from the first groove consists of a first inclined surface, a first vertical surface, and a second inclined surface connected sequentially from top to bottom. Alternatively, the side of clamping block 2 away from the first groove consists of a first inclined surface, a first arc-shaped surface, and a second inclined surface connected sequentially from top to bottom. Or, the side of clamping block 2 away from the first groove consists of a first inclined surface and a second inclined surface connected sequentially from top to bottom. The side of clamping block 2 inserted into the first groove consists of a third inclined surface and a fourth inclined surface connected sequentially from top to bottom. This structure makes clamping block 2 symmetrical, allowing for uniform opening and closing of the clamping block 2's opening, and reducing the requirements for installation direction. Furthermore, this structure also serves as a guide, facilitating insertion into the first groove. The left side of the clamping block 3 consists of a second vertical surface and a fifth inclined surface connected sequentially from top to bottom. The inclination angle of the fifth inclined surface is the same as that of the third inclined surface. When the clamping block 3 moves downward, the fifth inclined surface of the clamping block 3 presses against the third inclined surface of the clamping block 2, thereby forcing the clamping block 2 to move to the left, that is, to move to the outside of the first groove.

[0030] The height of the bottom of the second groove is preferably less than the height of the groove wall above the first groove, but greater than the height of the lower edge of the third inclined surface. This ensures that the junction of the third and fourth inclined surfaces of the clamping block 2 can effectively abut against the bottom of the groove, thereby guaranteeing the support strength of the clamping block 2.

[0031] A first bolt mechanism is connected to the clamping block 3, which drives the clamping block 3 to slide up and down along the second groove. A first bolt hole 5 is opened on the bottom of the second groove, with the first bolt hole 5 facing the same direction as the second groove. A first through hole is opened on the clamping block 3 at a position corresponding to the first bolt hole. A first bolt 4 passes through the first through hole and is screwed into the first bolt hole. The first bolt 4, the first bolt hole, and the through hole constitute the first bolt mechanism. This allows the position of the clamping block 3 to be adjusted using the limiting first bolt, and after adjustment, the position of the clamping block 3 can be fixed, thereby fixing the position of the clamping block 2. A spring can be fitted onto the first bolt, with one end of the spring abutting against the clamping block 3 and the other end abutting against the bottom of the second groove. Thus, after the first bolt is removed, the spring force causes the clamping block 3 to move upward and reset. A countersunk hole is provided at the top of the through hole, thereby accommodating the bolt head and preventing the bolt head from being exposed.

[0032] Lubricating oil can be provided between the clamping block 3 and the holding block 2 to improve wear during their relative movement. In this case, the contact surface of the clamping block 3 is preferably provided with oil guiding grooves.

[0033] Specific embodiment 2, such as Figure 2 As shown

[0034] The clamping block 3 is located within the first groove, and the clamping block 2 and the clamping block 3 are in close contact. A second bolt mechanism is connected to the clamping block 3 to drive it to slide along the first groove. Preferably, the support rod 1 has a second bolt hole that communicates with the first groove, and a second bolt 9 passes through the second bolt hole and is fixedly connected to the clamping block 3. This allows the position of the clamping block 3 to be adjusted using the limiting second bolt 9, and after adjustment, the position of the clamping block 3 can be fixed, thereby fixing the position of the clamping block 2.

[0035] In this embodiment, the side of the clamping block 2 away from the first groove is composed of a first inclined surface, a first vertical surface, and a second inclined surface connected sequentially from top to bottom. Alternatively, the side of the clamping block 2 away from the first groove is composed of a first inclined surface, a first arcuate surface, and a second inclined surface connected sequentially from top to bottom. Alternatively, the side of the clamping block 2 away from the first groove is composed of a first inclined surface and a second inclined surface connected sequentially from top to bottom. The side of the clamping block 2 near the clamping block 3 is not limited and can be a plane or the shape shown in specific embodiment 1.

[0036] Yes, the clamping block 3 and the holding block 2 can be combined, eliminating the need for a separate clamping block 3. The second bolt directly connects to the holding block 2. However, it is preferable to include a clamping block 3. This facilitates the replacement of the holding block 2, addressing the issue of its easy wear and replacement.

[0037] In both embodiments described above, the clamping block 2 is preferably made of an elastic material. Thus, as the clamping block 2 delves deeper into the first groove, the opening of the clamping block 2 gradually decreases until it clamps the side wall of the annular bend.

[0038] In both embodiments described above, it is preferable that the support rod 1 has a downward-facing third bolt hole at its lower end, which is used to connect to the external base. There are at least three third bolt holes, with a spacing between adjacent holes to increase connection stability and prevent rotation of the support rod 1.

[0039] In both of the above embodiments, preferably, the notch of the clamping block 2 can be covered with a functional layer 8, such as... Figure 4 As shown. For example, the functional layer can be an anti-slip layer made of anti-slip material, a wear-resistant layer made of wear-resistant material, or a metal plating layer. The recess can also have strip-shaped protrusions or grooves, which serve as the functional layer.

[0040] In both embodiments described above, preferably, a downward-facing limiting hole 7 is provided below the support rod 1. A limiting member is inserted into the limiting hole 7, guiding the connection between the support rod 1 and the external base, thus facilitating the connection. Preferably, the limiting member is partially inserted into the limiting hole and partially exposed outside the limiting hole. The outer contour of the limiting member's cross-section is preferably polygonal to prevent the support rod 1 from rotating. The depth of the limiting hole 7 can be no less than half the minimum distance from the second groove to the bottom of the support rod. This limits the position of the support rod using the limiting member. A separate connecting bolt can be omitted from the support rod; instead, the limiting member can be used for direct external connection. The limiting hole is preferably located at the center. The support rod can rotate around the limiting member to adjust the orientation of the notch, thereby adapting to the snapping of irregular parts of the annular tube.

[0041] In both of the above embodiments, it is preferred that a support plate 6 is also included, such as... Figure 3 As shown, the support plate 6 is connected below the support rod 1, and the cross-sectional area of ​​the support plate 6 is larger than that of the support rod 1. This increases the area of ​​the support rod 1, allowing it to be more stably connected to the base. The support plate may have fourth bolt holes, which are used to connect to the third bolt holes of the support rod 1, thus completing the connection between the support plate and the support rod 1. The support plate can be square or circular. Preferably, the support plate is circular, reducing the angle requirements during installation. The number of fourth bolt holes 10 on the support plate is greater than the number of third bolt holes on the support rod 1, allowing for adjustment of the relative position of the support rod 1 and the support plate by selecting different bolt holes during use, thereby enabling the fixing of more sizes of annular bends. The fourth bolt holes 10 are preferably arranged in a ring. This provides more selectable values ​​for the distance between two fourth bolt holes, accommodating support rods 1 with different third bolt hole spacings.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
