Description

Technical Field

[0001] The utility model belongs to the technical field of warp frames, in particular to a warp frame for a circular loom. Background Art

[0002] In order to enhance the strength of the connecting structure in the warp frame, the prior art discloses a warp frame for a circular loom with application number CN202221671794.0, comprising at least two support rods arranged in a vertical direction and a cross rod arranged between the support rods. Several cross rods are arranged at intervals along the length direction of the support rods, and several support rod bodies for assembling warp tubes are provided on the cross rods. Each support rod is provided with an installation through hole for inserting the cross rod at the corresponding cross rod position. The bottom wall of the installation through hole is abutted against the cross rod to form a support structure. The structure also includes a fixing member passing through the support rod and the cross rod, and a locking structure for locking the fixing member on the support rod or the cross rod.

[0003] The cross bar and the support bar are only passed through a fixing piece and then locked with a locking piece, which can easily cause the cross bar to be squeezed inward and deformed. In addition, there are processing errors, and there are dimensional errors between the cross bar and the mounting through hole, which can easily cause the cross bar to swing in the mounting through hole, causing the locking piece to loosen and the fixing piece to fall off, posing a safety hazard. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a circular loom warp frame, which avoids the problem that the warp frame cross bar is squeezed by a single fixing part and a locking part and is excessively deformed inward, and the cross bar shakes at its connection.

[0005] The technical solution of the present utility model is as follows: a circular loom warp frame, comprising a plurality of vertically arranged uprights and a plurality of cross bars arranged between adjacent uprights, each cross bar is provided with a plurality of positioning rods for assembling warp tubes, and mounting through holes for inserting the ends of the cross bars are provided between adjacent uprights. The cross bar is a tubular structure, and the cross bar includes two vertical mounting side walls, which extend into the mounting through holes and are respectively fixed to the inner walls of the mounting through holes by mounting components, and each of the mounting components is symmetrically arranged in pairs around the central axis of the uprights.

[0006] By adopting the above technical solution, the cross bar is inserted into the mounting hole and assembled to the vertical pole, and the two mounting side walls of the cross bar are respectively fixed to the vertical pole by using the mounting assembly, so as to avoid the deformation of the cross bar as a whole caused by excessive squeezing and the shaking of the cross bar in the mounting hole, and prevent the weight of the cross bar from acting entirely on one mounting assembly, so that it is distributed on different mounting assemblies on the two mounting side walls, which correspondingly increases the service life of the mounting assembly, and can prevent the damage of a single mounting assembly. Its symmetrical mounting assembly can continue to fix the cross bar on the vertical pole, and the mounting hole can also temporarily support the cross bar, making it more stable when used. Moreover, it is a detachable connection, and it takes up less space after disassembly, which is convenient for transportation and reduces transportation costs.

[0007] The utility model is further configured as follows: the installation assembly includes a fixing member and a locking member, the fixing member passes through the vertical rod and the horizontal rod and is locked by the locking member, and the fixing member and the locking member are respectively a matching bolt and a nut.

[0008] By further adopting the above-mentioned setting, the fixing part and the locking part are locked by threads, and there is no need to set threads on the vertical poles, horizontal poles or end connecting rods of large parts, making it easier to process, and the bolts and nuts are used for locking, which makes the assembly simple and the structure firm.

[0009] The present invention is further configured as follows: the vertical rods and the horizontal rods are both square tube structures, and the mounting through holes are square through holes.

[0010] With the above further arrangement, the cooperation of the square can effectively prevent the crossbar from rotating. At the same time, the square has two pairs of symmetrical planes, which facilitates the stable arrangement of the fixing member and the locking member.

[0011] A further configuration of the present invention is that the cross bar is provided with a strip-shaped through hole for passing the fixing piece.

[0012] By adopting the above further setting, the position of the cross bar can be fine-tuned when the cross bar passes through the fixing parts to compensate for the error caused by processing. The bottom surface of the cross bar can be controlled to abut against the bottom surface of the mounting through hole, and supported by the mounting through hole, further reducing the effect of the gravity of the cross bar on the mounting assembly.

[0013] The utility model is further configured as follows: the positioning rod is welded or sleeved on the cross bar, the positioning rod comprises a positioning sleeve and a sleeve rod fixed on the positioning sleeve, and each positioning rod sleeve rod is arranged tilted upward in a direction away from the cross bar.

[0014] With the above-mentioned further setting, the positioning rod is sleeved on the cross bar, and the position of the positioning rod on the cross bar can be manually adjusted. When it is fixed to the cross bar by welding, the positioning rod is fixed more firmly and is tilted upward from the inside to the outside. When the warp tube is sleeved on the positioning rod, it is affected by gravity and slides to the bottom and is supported by the positioning sleeve or the cross bar, effectively preventing the warp tube from falling off.

[0015] A further configuration of the present invention is that a plug is provided at the outer opening of each of the mounting through holes.

[0016] With the above further arrangement, the provided plug can be used to seal the outwardly open opening of the installation through hole, thereby keeping the vertical pole beautiful and neat, and preventing the outside world from affecting the locking part, causing the locking part and the fixing part to loosen or even fall off.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being described. In the description of this utility model, "several" means at least two, such as two or three, unless otherwise specifically defined.

[0030] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0031] like Figure 1-Figure 7 As shown, a warp frame of a circular loom includes two vertically arranged uprights 1 and nine cross bars 2 arranged between adjacent uprights 1, and each cross bar 2 is sleeved with a number of positioning rods 9 for assembling warp tubes. The positioning rod 9 includes a positioning sleeve and two sleeve rods symmetrically fixed on the positioning sleeve, and the sleeve rod of each positioning rod 9 is tilted upward away from the end of the cross bar 2. The positioning rod 9 is sleeved on the cross bar 2 through the positioning sleeve, and the position of the positioning rod 9 can be manually slid on the cross bar 2 to adjust the position of the positioning rod 9, so that the warp tube can be reasonably and evenly distributed on one cross bar 2. The positioning rod 9 can also be enhanced by directly welding the positioning sleeve to the cross bar 2. The two sleeve rods of each positioning rod 9 are tilted upward away from the positioning sleeve, so that when the warp tube is sleeved on the positioning rod 9, the bottom of the warp tube slides to the bottom of the positioning rod 9 under the action of gravity and is supported by the cross bar 2, thereby effectively preventing the warp tube from falling off.

[0032] Mounting holes 3 for inserting the ends of the cross bars 2 are provided between adjacent vertical bars 1. The cross bars 2 are inserted into the mounting holes 3 to form a supporting structure. The cross bars 2 and the vertical bars 1 are fixed by setting mounting components.

[0033] The vertical pole 1 and the horizontal pole 2 are all square tube structures. There are four symmetrical side surfaces in the circumferential direction of the vertical pole 1 and the horizontal pole 2. Therefore, each horizontal pole 2 includes two symmetrical mounting side walls 21 that are flush with the vertical side walls of the vertical pole 1. Each mounting side wall 21 is fixed to the vertical pole 1 by passing through a mounting component, and the two mounting components can be symmetrically arranged around the central axis of the vertical pole 1.

[0034] The two mounting side walls 21 extend into the mounting through-holes 3 and are respectively fixed to the inner walls of the mounting through-holes 3 by a mounting assembly. The mounting assembly includes a fixing piece 4 and a locking piece 5. The fixing piece 4 and the locking piece 5 are respectively provided with a threaded structure that engages with each other. The fixing piece 4 can be a bolt, and the locking piece 5 can be a nut. After the fixing piece 4 passes through the vertical pole 1 and the corresponding mounting side wall 21, it is locked by the locking piece 5. The head of the bolt is in close contact with the outer wall of the vertical pole 1, and the screw part of the bolt is locked with the nut in the mounting through-hole 3. The locking of the fixing piece 4 and the locking piece 5 achieved by the thread causes the mounting side wall 21 to squeeze the inner wall of the mounting through-hole 3, effectively avoiding the inward extrusion and deformation of the cross bar after tightening, and affecting the shaking of the cross bar in the mounting through-hole 3. There is no need to set threads on the vertical pole 1, cross bar 2 or end connecting rod 7 of the large part, making its processing simpler. It is more convenient to directly select the matching bolts and nuts for fixing, and it is simple to assemble and has a firm structure.

[0035] The installation side wall 21 is provided with a strip-shaped through hole for passing the fixing piece 4. When the fixing piece 4 is passed through to assemble the cross bar 2, the position of the cross bar 2 can be fine-tuned to compensate for the error caused by processing. It can ensure that the bottom surface of the control cross bar 2 can abut against the bottom surface of the installation through hole 3, so that it is supported by the vertical pole 1, further reducing the effect of the gravity of the cross bar 2 on the installation assembly.

[0036] A plug 8 is provided at the opening of the mounting through hole 3 facing outward and away from the cross bar 2 to seal the opening, keep the vertical pole 1 beautiful and neat, and prevent the outside from affecting the locking piece 5 so that the locking piece 5 and the fixing piece 4 may become loose or even fall off.

[0037] The mounting through hole 3 is a square through hole for inserting the square cross bar 2. After insertion, the assembly is stable, which can effectively prevent the cross bar 2 and the end support rod 7 from rotating, so that the warp tube set above the cross bar 2 can be stably placed. At the same time, the square has two pairs of symmetrical planes, which is convenient for the stable and symmetrical setting of the installation components.

[0038] like Figure 8 、 Figure 9As shown, the above-mentioned two vertical poles 1 and nine horizontal poles 2 constitute a warp wire rack, and adjacent warp wire racks are connected by end support rods 7. Connection holes 6 are opened at the top and bottom ends of the vertical poles 1, and the end support rods 7 are inserted into the connection holes 6 to form a supporting structure. Thus, two adjacent warp wire racks are connected by setting four end support rods 7. The end support rods 7 are perpendicular to the warp wire rack composed of the vertical poles 1 and the horizontal poles 2, and together form a rectangular structure, which can stand stably on the ground.

[0039] The end support rod 7 is fixed to the vertical pole 1 by setting up four mounting components, and two mounting components form a group. The mounting components in each group are symmetrically arranged with respect to the central axis of the vertical pole 1. The installation method of the mounting components is the same as the installation between the above-mentioned cross bar 2 and the vertical pole 1. The end support rod 7 is a square tube structure, and the connecting hole 6 is a square through hole that can be inserted into the end support rod 7.

[0040] The end connecting rod 7 may also be provided with a through hole for passing the fixing piece 4 , which is a strip-shaped through hole, for fine-tuning the installation position of the end connecting rod 7 on the column 1 .

[0041] Specifically, the cross bar 2 is inserted into the mounting hole 3 and assembled to the vertical pole 1, and the end connecting rod 7 is inserted into the connecting hole 6 and assembled to the vertical pole 1, forming a rectangular body structure that can be stably placed on the ground. Each of the two mounting side walls 21 of the cross bar 2 and the mounting wall of the end connecting rod 7 are each provided with at least one mounting component passing through to fix it on the vertical pole 1. The locking piece 4 is located in the mounting hole 3 or the connecting hole 6, so that the mounting side wall 21 is close to the inner wall of the mounting hole 3, effectively avoiding the cross bar 2 caused by being locked by a single fixing piece and a locking piece. Inward deformation prevents the cross bar 2 or the end connecting rod 7 from shaking relative to the vertical rod 1, and prevents the weight of the cross bar 2 or the end connecting rod 7 from acting entirely on one mounting component, so that it is evenly distributed on the remaining mounting components, which can increase the service life of the mounting components and prevent other mounting components from continuing to fix the cross bar 2 on the vertical rod 1 after a single mounting component is damaged. The mounting through hole 3 can also temporarily support the cross bar 2, making it more stable when used. It is a detachable connection, and after disassembly, it occupies less space and is convenient for transportation, reducing transportation costs.
