Description

Technical Field

[0001] The utility model relates to the technical field of spray room equipment installation, in particular to a cross arm support quick-insertion structure for a spray room. Background Art

[0002] As is known, quick-connection and bolt connection are common connection structures for on-site construction and installation of equipment, which can reduce the cost and difficulty of welding construction. Because the spraying room has many conveying tracks and suspended parts, a large number of support rod racks are required for support rack installation. The traditional simple support rod rack generally includes three parts: vertical pole, cross arm and diagonal brace. The vertical pole and the cross arm are vertical. Therefore, in order to achieve quick connection, a positioning block is first fixed vertically on the vertical pole for the cross arm to be inserted. After the cross arm is inserted in place, it is respectively connected and fixed with the positioning block and the diagonal brace by bolts.

[0003] However, usually the vertical poles, cross arms and diagonal braces are all designed as pipe fittings. In order to save costs, bolts will not penetrate the entire rod and then screw nuts to connect. However, if only connecting holes are set on the wall of the pipe, it is not easy to insert tools into the pipe fittings to screw nuts or bolts. The solution is to weld nuts in advance at the corresponding positions of the positioning blocks and the diagonal braces, and then set corresponding connecting holes on the cross arms. When the cross arms are inserted into place, the bolts or screws are directly screwed through the connecting holes and the fixed nuts. However, this connection method still has the following defects: welding nuts on pipe fittings in advance will still increase welding costs, and thin-walled pipe fittings are prone to deformation during welding, which increases the difficulty of welding. After welding is completed, once the exposed nuts collide during transportation and assembly, they will also cause deformation, making it inconvenient to screw the bolts, thereby scrapping the entire pipe fitting. In addition, the cross arms need to be bolted to the vertical poles and diagonal braces at two corresponding positions respectively, which is very troublesome. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a quick-insertion structure for a cross arm support of a spray booth, which can reduce the cost and difficulty of disassembly and assembly and improve the convenience of disassembly and assembly.

[0005] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0006] The lockhole that is formed on the upper and lower ends of the support frame is formed on the upper and lower ends of the support frame, and the lockhole that is formed on the upper and lower ends of the support frame is formed on the support frame.

[0007] Furthermore, four plug plates are provided on four sides of the outer end surface of the inner tube seat, the vertical rod is configured as a square tube, and the tube wall of the square tube is provided with a socket for correspondingly plugging in the plug plates for welding positioning.

[0008] Furthermore, the inserting strips are provided with two and are symmetrically fixed on both sides of the upper end surface of the diagonal support member.

[0009] Furthermore, an extension plate is provided on the outer side of the upper end surface of the diagonal bracing member, and the extension plate is connected to the lower tube wall of the cross arm tube by screws.

[0010] Furthermore, each side wall of the inner tube seat is provided with a plurality of mounting holes.

[0011] Furthermore, the mounting hole is configured as a waist-shaped long hole whose length is along the axial direction of the inner tube seat, and the hole wall at one end of the waist-shaped long hole is widened to form two symmetrical steps, and the step surfaces of the steps are configured as inclined surfaces inclined outwardly toward the other end of the waist-shaped long hole, and the distance between the two steps is narrowed to be smaller than the width of the other end of the waist-shaped long hole; the clip nut comprises a nut body and two elastic clips symmetrically fixed on both sides of the nut body, and the upper end of the elastic clip is concave to form a slot adapted to clamp the corresponding hole edge of the narrow part of the waist-shaped long hole.

[0012] Furthermore, a height adjustment component is provided at the bottom end of the vertical pole.

[0013] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0014] The quick-insertion structure of the cross arm support of the spray room disclosed by the utility model is different from the traditional nut welding form. It adopts a card nut quick-release card installation method to connect the cross arm pipe, which avoids welding deformation while ensuring convenient installation and facilitating replacement, thereby greatly reducing the cost and installation difficulty. The card connection of the plug strip itself and the plug seam to the long strip hole can not only effectively support and limit the cross arm rod, but also improve the convenience of disassembly and assembly.
