Description

Technical Field

[0001] The utility model relates to the technical field of automobile glass logistics transportation packaging, in particular to a universal backrest limiting component of an automobile glass packaging and transportation frame. Background Art

[0002] Traditionally, the rear backrest retaining technology for automotive glass packaging and transport racks involves attaching protective materials like foam or rubber to the rear backrest square tube. Alternatively, the curvature of the glass at a fixed location is extracted and CNC-machined to match the protective material's shape or angle, or the square tube is adjusted to accommodate the curvature. Adjusting this curvature during the packaging process is difficult and limited, making it incompatible with a wide range of glass types. Improper angles often lead to unilateral or angular contact between the glass and the rear backrest retainer, resulting in cosmetic defects or cracks during transport. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a universal backrest limiter for an automobile glass packaging and transporting rack.

[0004] The technical solution adopted by the utility model is a universal backrest limiter for an automobile glass packaging and transporting rack, comprising a vertical square tube, the outer side wall of the vertical square tube being vertically fixed to a horizontal square tube, the vertical square tube being slidably connected to the rear backrest square tube of the packaging and transporting rack, a plurality of through holes being vertically spaced apart on the rear backrest square tube, a hole being provided on the outer side wall of the vertical square tube and a plug-in pin being inserted into the through hole of the rear backrest square tube for height limiting, a connecting rod being provided in the horizontal square tube, one end of the connecting rod being located inside the horizontal square tube and being pivotally connected to the horizontal square tube up and down, the other end of the connecting rod being located outside the horizontal square tube and being pivotally connected to the back side of a back plate left and right, a rubber pad being provided on the front side of the back plate in contact with the glass.

[0005] Furthermore, a first fixed shaft is transversely arranged on the transverse square tube, and one end of the connecting rod is rotatably connected to the first fixed shaft.

[0006] Furthermore, a second fixed shaft is vertically arranged at the other end of the connecting rod, and two connecting ears are spaced apart on the back of the support plate, and the two connecting ears are rotatably connected to the two ends of the second fixed shaft.

[0007] Furthermore, the lower end of the square tube of the rear backrest is arranged obliquely toward the front.

[0008] The utility model has the following beneficial effects:

[0009] 1. Simple materials and easy production facilitate later maintenance and replacement. It can be adjusted up and down to meet the requirements of glass of different heights and curvatures. This provides maximum contact protection with the glass and avoids contact with the glass from one side or one angle, which may cause uneven force on the glass during transportation.

[0010] 2. The present invention does not adopt the traditional idea of ​​designing the backrest limiter to conform to the curvature of the glass. Instead, the force of the glass leaning back causes the backrest limiter to be stressed, and the angle of the backrest limiter is formed following the curvature of the glass to meet the maximum contact area.

[0011] 3. It can adapt to the curvature of different automobile glasses, realize the versatility of packaging and transportation boxes, and achieve the purpose of one box for all. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a universal backrest limiter for an automobile glass packaging and transporting rack of the present invention in conjunction with the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, a universal backrest limiter for an automobile glass packaging and transport rack comprises a vertical square tube 1, the outer side wall of the vertical square tube 1 being vertically fixed with a horizontal square tube 2, the vertical square tube 1 being slidably connected to a rear backrest square tube 91 of a packaging and transport rack 9, a plurality of through holes being vertically spaced on the rear backrest square tube 91, a hole being provided on the outer side wall of the vertical square tube 1 and a plug-in pin 3 being inserted into the through hole of the rear backrest square tube 91 for height limitation, a connecting rod 5 being provided in the horizontal square tube 2, one end of the connecting rod 5 being located inside the horizontal square tube 2 and being pivotally connected to the horizontal square tube 2 up and down, the other end of the connecting rod 5 being located on the outer side of the horizontal square tube 2 and being pivotally connected to the back side of a back plate 7 left and right, a rubber pad 8 being provided on the front side of the back plate 7 in contact with the glass.

[0017] The design and application of the universal backrest limiter of the utility model breaks the traditional thinking and frees the packaging designers and packaging manufacturers from the process-oriented technical difficulties of "obtaining the two-dimensional curvature of the support surface at a certain position of the glass and CNC processing the protective material according to the two-dimensional curvature of the glass". The utility model does not provide a separate two-dimensional curvature according to any glass product. Instead, during the packaging process of the automobile glass, the force of the glass leaning backward causes the universal backrest limiter to be subjected to the force to achieve the maximum contact area, which not only avoids complex technical problems but also cleverly meets the needs.

[0018] In this embodiment, the lower end of the rear backrest square tube 91 is tilted forward, creating a slight angle with the glass. This angle can then be adjusted using the universal backrest stopper of the present invention. This universal backrest stopper is mechanically welded together using conventional 50*50 square tubes, 20*20 square tubes, round steel, nuts, shaft pins, and plug-in latches.

[0019] A first fixed shaft 4 is transversely mounted on the transverse square tube 2. One end of a connecting rod 5 is pivotally connected to the first fixed shaft 4. A second fixed shaft 6 is vertically mounted on the other end of the connecting rod 5. Two connecting lugs are spaced apart on the back of a support plate 7 and pivotally connected to the ends of the second fixed shaft 6. The rubber pad 8, where it contacts the vehicle's glass, is made of a highly elastic rubber material, and the contact surface does not react with the glass.

[0020] During use, the universal backrest limiter can be adjusted up or down by adjusting the latch 3 to the desired height, depending on the height of the glass product. The first fixed axis 4 can be adjusted to match the longitudinal curvature of the glass contact point, while the second fixed axis 6 can be adjusted to match the transverse curvature. This utility model has been applied to the rear backrest limiter of the GT710 universal windshield canopy rack, suitable for loading and transporting a variety of windshield and canopy products.

[0021] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
