Description

TECHNICAL FIELD

[0001] The utility model belongs to glass package technical field, concretely relates to a kind of packing frame side baffle locking device. BACKGROUND

[0002] The packaging and transportation of high-generation TFT-LCD glass substrates is a critical link in the industry chain, requiring the glass substrates to be flatly grabbed and loaded in a dust-free environment, and each substrate and spacer paper must be neat and uniform. After loading 200 to 300 pieces, side baffles need to be installed around the frame body to fix the four edges of the glass, so that the glass substrates are not dislocated or rubbed during transportation to produce dust, and the glass substrates are transported to the downstream panel customers intact. The traditional fastening method requires accurate positioning at the initial installation and uses tools for tightening. This process not only consumes time and effort, but also requires higher skills from the operator. In addition, due to the risk of loosening of the fasteners themselves, and repeated stress due to factors such as vibration and impact during transportation, the fasteners can gradually loosen, affecting the stability and protection effect of the side baffles. When the side baffles fall off due to loosening of the fasteners, not only will the contents of the package be damaged, but also safety hazards may occur to the transportation tools and surrounding environment. Especially in long-distance transportation or adverse weather conditions, this risk is more pronounced.

[0003] Some improved packaging frame side baffle fixing devices are available, but these devices often have complex structures, high costs, and certain limitations in actual application. For example, although some devices can achieve quick installation and disassembly, their locking effect and stability still need to be improved. Other devices rely too much on external tools or additional devices for locking, increasing the complexity and inconvenience of operation. UTILITY MODEL CONTENTS

[0014] Preferably, the positioning part is circular, and the locking part is long strip-shaped.

DETAILED DESCRIPTION

[0021] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0022] like Figure 1 As shown, a side panel locking device for a packaging rack is used to lock the packaging rack and the side panel 2. The packaging rack includes a frame body, and a positioning locking hole 1 is provided on the side wall of the frame body. The positioning locking hole 1 includes a positioning part 11 and a locking part 12. The side panel 2 is provided with an installation hole, and an insert rod 3 is installed in the installation hole. The front and rear ends of the insert rod 3 are respectively fixedly connected to a limit handle 5 and a positioning pin 4. The positioning pin 4 is inserted into the positioning part 11 of the positioning locking hole 1 and extends to the rear side of the positioning part 11. Then, the insert rod 3 can be operated to be inserted into the locking part 12 of the positioning locking hole 1. Through the phased cooperation of the positioning part 11 and the locking part 12, a double locking function is achieved, which not only ensures the initial positioning accuracy, but also enhances the stability through gravity self-locking, effectively preventing the side panel 2 from loosening due to vibration during transportation. The structure is simple, the cost is low, the disassembly is convenient, and it can be reused.

[0023] Furthermore, a first limiting block 6 and a second limiting block 7 are provided on the outside of the mounting hole to restrict the rotation of the limiting handle 5. The first limiting block 6 and the second limiting block 7 form a rigid constraint space, which restricts the degree of freedom of the handle and avoids accidental rotation and unlocking of the plug rod 3 due to misoperation or external impact, thus significantly improving the locking reliability.

[0024] Specifically, the first limiting block 6 and the second limiting block 7 are arranged symmetrically about the mounting hole, and both are horizontally positioned on their plate surfaces. This ensures that the force on the limiting handle 5 is evenly distributed, reducing the risk of unilateral wear, while also enhancing the overall structural strength of the device and extending its service life. The first limiting block 6 and the second limiting block 7 are plate-shaped. Plate structures are easy to process and have high bending stiffness, achieving efficient limiting within a limited space while reducing manufacturing costs.

[0025] Furthermore, an elastic element is provided on the front side of the mounting hole. The two ends of the elastic element abut against the side baffle 2 and the limiting handle 5 respectively, providing continuous pre-tightening force to compensate for assembly gaps, eliminate loosening caused by processing errors or wear, and absorb vibration energy during transportation to reduce the risk of abnormal noise.

[0026] Specifically, the elastic element uses a U-shaped rubber strip, whose U-shaped structure combines elastic deformation capability and fatigue resistance. The rubber material is resistant to aging and has a high coefficient of friction, which can maintain a stable pre-tightening effect for a long time. It can be used as a temporary fixation for packaging, or after being perforated, it can be sleeved on the outside of the insertion rod 3 to improve stability.

[0027] Specifically, the side baffle 2 comprises a main baffle part 21, a connecting part 22 and a locking part 23 in sequence, the connecting part 22 is connected to the main baffle part 21 and the locking part 23 at both ends, the locking part 23 is arranged in a staggered manner relative to the main baffle part 21 through the connecting part 22, and a mounting hole is arranged on the locking part 23, so that an avoiding space is formed, and an operator can conveniently observe and adjust the position of the inserting rod 3.

[0028] Specifically, the positioning pin 4 is in a circular plate shape, which is convenient for adapting to the circular profile of the positioning part 11, realizes quick alignment without direction, shortens the assembly time, and increases the contact area to disperse the locking stress. The inserting rod 3 is also in a cylindrical shape, and the cylindrical inserting rod 3 and the long strip-shaped hole of the locking part 12 form a sliding pair, which is automatically returned and locked under the action of gravity, and simplifies the operation process.

[0029] Specifically, the positioning part 11 is in a circular shape, and the locking part 12 is in a long strip shape, and the two are connected in the middle. After being connected, the positioning and locking hole 1 is symmetrical to the left and right. The positioning part 11 in a circular shape and the locking part 12 in a long strip shape are combined to form a guide locking channel. The coarse positioning is realized through the circular part, and then the accurate locking is realized through the long strip-shaped part, which takes into account the positioning accuracy and the operation fault tolerance.

[0030] In use, first, the frame body with glass or in an empty state is placed horizontally, then the limiting handle 5 is placed outside the first limiting block 6 and the second limiting block 7, the positioning pin 4 is aligned with the positioning part 11 of the positioning and locking hole 1, the positioning pin 4 is inserted into the positioning part 11, then the inserting rod 3 moves downward into the locking part 12 under the action of gravity, then the limiting handle 5 is pressed into the first limiting block 6 and the second limiting block 7, the positioning pin 4 is tightly pressed against the side wall of the frame body by extruding the elastic member, and the limiting handle 5 cannot be turned over due to the blocking of the first limiting block 6 and the second limiting block 7, so that the side baffle 2 is locked and avoids shaking up and down and displacement. Repeating the operation, the locking device of a set of matched packaging frame and side baffle 2 is completed, the four edges of the glass substrate are fixed, and transportation is facilitated.
