[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only the preferred embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Shelf structure such as Figure 4 As shown, the shelf is a gantry structure, which is stacked and limited by the upper guide angle steel 01 and the lower guide angle steel 05. The upper door beam of the shelf is open, and at the same time, the rear upright 02 is recessed. In this way, the shelf can be stacked and stored in an interlocking manner.

[0022] This embodiment provides a rack manufacturing jig, which can be used for... Figure 4 The welding and assembly of the medium-sized shelving units are designed to accommodate the manufacturing of shelving units of various widths, such as... Figures 1-3 As shown, the shelving manufacturing rack is designed as a track-type adjustable structure, which includes an upper horizontal rail 1, a lower horizontal rail 6, a side frame unit 4, and a base frame unit 5. The two upper horizontal rails 1 and the two lower horizontal rails 6 are arranged horizontally to form the frame-shaped upper and lower guide and upper and lower support of the rack as a whole.

[0023] Two side frame units 4 are used to divide the shelf into left and right structural units for initial assembly. They are longitudinally set between the upper horizontal rail 1 and the lower horizontal rail 6. The fixed position of the two side frame units 4 can be adjusted laterally according to the width specification of the shelf.

[0024] Among them, refer to again Figure 2The side frame unit 4 comprises a side frame, an upper guide support 21, a lower guide support 42, a longitudinal positioning rod 43, a straightening column and a limiting device, and the side frame is in a side U-shaped frame structure to facilitate the assembly and convenient disassembly of the shelf.

[0025] The upper guide support 21 is arranged on the top frame body of the side frame and is used for positioning the upper guide angle steel 01 of the shelf, and the lower guide support 42 is fixedly arranged on the bottom frame body of the side frame and is used for positioning the lower guide angle steel 05 of the shelf. The upper guide support 21 and the lower guide support 42 are arranged along the longitudinal direction, and the positions of the two are corresponding. The lower end of the upper guide support 21 is provided with an L-shaped limiting groove, and the upper end surface of the lower guide support 42 is provided with an L-shaped limiting surface.

[0026] The four straightening columns are respectively used for abutting against the four side columns 02 of the shelf. The straightening columns are fixed between the top frame body and the bottom frame body, and the longitudinal inner side surface of the straightening column abuts against the longitudinal outer side surface of the side column 02. The limiting device 3 is arranged beside the straightening column. After the longitudinal side support 03 is assembled between the front side column 02 and the rear side column 02, the limiting device 3 is used for positioning the transverse outer side surface of the side column 02 and applying a pressing force from both sides, so that the connection between the side column 02 and the longitudinal side support 03 is stable, and the spot welding initial assembly is facilitated. The limiting device 3 of the rear straightening column 44 can be a fixed limiting plate, and the limiting device 3 of the front straightening column 41 can be a movable or detachable limiting plate.

[0027] The two longitudinal positioning rods 43 are arranged on the bottom frame body in the longitudinal direction, and the opposite surfaces of the two are provided with L-shaped positioning grooves, which are used for placing and positioning the longitudinal side support 03.

[0028] After the initial assembly of the structure units on both sides of the shelf is completed, the position of the side frame unit 4 is adjusted, and a plurality of bottom frame units 5 are appropriately laid between the two side frame units 4. The feet of the two ends of the bottom frame unit 5 are sleeved on the two lower cross rails 6, which are used for supporting and placing the transverse side support 04 and the inner support 06.

[0029] As a further technical solution, in order to facilitate the application of the pressing force and the disassembly of the shelf, the limiting device 3 is preferably a movable limiting structure, and the limiting device 3 is further referred to as Figure 3 which comprises a mounting base plate 31, a crank rocker mechanism and a limiting lock plate 36. The crank rocker mechanism comprises a driving crank 32, a driving link 34 and a driven lock rod 35 which are connected in sequence by a pin. A driving handle 33 is connected with the driving crank 32 through a shaft connection arranged on the mounting base plate 31, and the limiting lock plate 36 is connected with the driven lock rod 35. The limiting lock plate 36 has a locking plane. In order to avoid the excessive rotation of the driving crank 32, the locking plane is limited by the transverse outer side surface of the column 02 to reach the dead point position of the crank rocker mechanism, and the crank rocker mechanism enters the limiting locking state. The locking plane is simultaneously abutted on the transverse outer side surface of the column 02 and the straightening column. At the dead point position of the driven lock rod 35, the limiting lock plate 36 can provide a certain pressing force.

[0030] To further improve the support reliability in the locked state, the driven locking rod 35 includes an integral main body section and a connecting section. One end of the main body section is pinned to the mounting base plate 31, and the other end is pinned to the drive connecting rod 34 of the crank rocker mechanism. The connecting section is L-shaped and extends from the outside of the front straight column 41 to its inside. One end of the connecting section is perpendicularly connected to the main body section, and the other end is perpendicularly provided with a limiting locking plate 36. Since the locking plane is perpendicular to the main body section, the force direction on the locking plane follows the direction of the main body section, avoiding damage to the stable support state when the crank rocker mechanism is at the dead point position. To further enhance the stability, in the limited locking state, the drive connecting rod 34 is perpendicular to the main body section.

[0031] As a further technical solution, the manufacturing frame should be adapted to the position of the upper guide angle steel 01 to adapt to the change of shelf height. The upper guide support is set on the upper positioning mechanism 2. The upper positioning mechanism 2 includes a synchronous frame 23 and a lifting cylinder 22. The two ends of the upper guide support are connected to the lower end of the guide column of the synchronous frame 23. The lifting cylinder 22 is installed on the top frame body. The top frame body is provided with two guide holes. The guide column can be slidably set in the guide holes. Under the drive of the lifting cylinder 22, the upper guide support is driven to rise and fall and maintain longitudinal horizontality.

[0032] As a further technical solution, the manufacturing rack should also adapt to changes in shelf depth. The straightening columns are divided into front straightening columns 41 and rear straightening columns 44. According to common specifications and models, multiple front straightening columns 41 are arranged longitudinally at the front end of the side frame, while the rear straightening columns 44 remain unchanged. In order to make full use of the limiting device 3, a longitudinal track 72 is provided on the longitudinal outer surface of the front straightening column 41. The limiting device 3 of the front straightening column 41 is installed on the sliding body 71, and it slides to the side of the corresponding front straightening column 41 through the sliding body 71. The limiting device 3 of the rear straightening column 44 is installed on the rear support column 45.

[0033] As a further technical solution, in order to prevent positioning interference caused by insufficient manufacturing precision of structural components, a clearance slot is opened at the corner of the limiting groove, and the corner of the limiting surface is flattened to form a clearance plane, which is used to make way for the edges of the upper guide angle steel 01 and the lower guide angle steel 05 respectively.

[0034] It should be noted that the slide rails and cross rails mentioned in this article are equipped with locking structures for position locking, such as lock holes and locking pins. This technology is a common means for those skilled in the art to achieve common adjustment functions, and will not be elaborated or limited in this article.

[0035] The directional terms "up," "down," "inside," "outside," "front," "back," "horizontal," "vertical," and "side" mentioned in this article are based on... Figures 1-3The directions and orientations shown in the corresponding figures are described. These terms are primarily for the purpose of better describing the present invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation;
