Description

Technical Field

[0001] This utility model relates to the field of packaging box handle technology, specifically a limiting handle for packaging boxes. Background Technology

[0002] In daily life, there are various packaging boxes with handles. The handles are mainly for the convenience of people to pick up goods and move objects. The existing handles are usually produced separately from the packaging box body. They are made by a combination of anti-detachment blocks at both ends of a handle and a fixing plate installed on the packaging box. The fixing plate is set in the cardboard packaging box, and then the anti-detachment blocks at both ends of the handle are fixed to the packaging box body through the fixing holes opened on the packaging box.

[0003] Since the handles are made of plastic, their bending strength is limited. When the handle is lifted upwards, the force is concentrated on the upper surface of the anti-detachment block. The anti-detachment block will deform due to the weight of the packaging box and the items stored inside, resulting in the handle separating from the fixing plate. Therefore, a limiting handle for packaging boxes is proposed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a limiting handle for packaging boxes to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a limiting handle for a packaging box, comprising a fixing plate and a handle strip, wherein both ends of the handle strip are connected to anti-detachment blocks extending through to the bottom of the fixing plate, and the bottom of the fixing plate is slidably provided with two sets of anti-detachment components sleeved on the outside of the anti-detachment blocks; The anti-detachment component includes a frame that is slidably connected to the bottom of the fixed plate. A U-shaped cover is fixed to the top of the frame. An L-shaped block that abuts against the top of the anti-detachment block is fixed inside the U-shaped cover. The end of the L-shaped block near the anti-detachment block has a chamfer. A groove is reserved on the top of the anti-detachment block. A rubber strip that engages with the groove is fixed to the bottom of the L-shaped block. An arc-shaped elastic plastic strip that adheres to the end face of the fixed plate is fixed to the top of the U-shaped cover.

[0006] As a preferred technical solution, both ends of the fixing plate are provided with extensions covering the upper surface of the arc-shaped elastic plastic strip, and the extensions and the fixing plate are integrally formed.

[0007] As a preferred technical solution, the top of the fixing plate is provided with two sets of clearance grooves, and the internal dimensions of the clearance grooves are adapted to the handle strip and the anti-detachment block.

[0008] As a preferred technical solution, each set of the frame has a constraint strip fixed on its front and back surfaces, and the outer wall of the constraint strip is slidably sleeved with an outer sleeve fixed to the bottom of the fixing plate.

[0009] As a preferred technical solution, the end face of the L-shaped block and the U-shaped cover form an insertion port, and the length of the insertion port is greater than the length of the anti-detachment block.

[0010] As a preferred technical solution, the handle strip and the anti-detachment block are integrally injection molded using a mold.

[0011] In summary, the present invention has the following main advantages: This invention uses an anti-detachment component to constrain the anti-detachment block, thereby improving the anti-bending strength of the anti-detachment block. At the same time, it ensures that the anti-detachment block always slides horizontally at the bottom of the fixing plate, preventing it from slipping off the fixing plate and causing the handle strip to detach. This makes the handle strip firmly and stably connected to the fixing plate, better supporting the weight of the items inside the packaging box. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0015] The embodiments of this utility model will be described below based on its overall structure.

[0016] A type of packaging box uses a limiting handle, such as Figures 1 to 6As shown, it includes a fixed plate 100 and a handle strip 110. Both ends of the handle strip 110 are connected to anti-detachment blocks 140 that extend through to the bottom of the fixed plate 100. The bottom of the fixed plate 100 is slidably provided with two sets of anti-detachment components 200 sleeved on the outside of the anti-detachment blocks 140. The anti-detachment component 200 includes a frame 210 slidably connected to the bottom of the fixed plate 100, a U-shaped cover 220 fixed to the top of the frame 210, an L-shaped block 250 fixed inside the U-shaped cover 220 that abuts against the top of the anti-detachment block 140, a chamfer 251 provided at one end of the L-shaped block 250 near the anti-detachment block 140, a groove 141 reserved at the top of the anti-detachment block 140, a rubber strip 252 fixed at the bottom of the L-shaped block 250 that engages with the groove 141, and an arc-shaped elastic plastic strip 230 fixed to the top of the U-shaped cover 220 that adheres to the end face of the fixed plate 100. Both ends of the fixing plate 100 are provided with extensions 130 covering the upper surface of the arc-shaped elastic plastic strip 230, and the extensions 130 and the fixing plate 100 are integrally formed. The top of the fixing plate 100 is provided with two sets of clearance grooves 120, and the internal dimensions of the clearance grooves 120 are adapted to the handle strip 110 and the anti-detachment block 140. The end face of the L-shaped block 250 and the U-shaped cover 220 form an insertion port 240, the length of which is greater than the length of the anti-detachment block 140.

[0017] First, place the fixing plate inside the top of the packaging box, aligning the clearance groove 120 with the hole on the packaging box. Simultaneously, apply relative external force to the two sets of bottom strips 210. The curved elastic plastic strip 230 deforms and generates a certain reverse force, aligning the middle of the insertion port 240 with the clearance groove 120. Next, insert the anti-detachment blocks 140 at both ends of the handle strip 110 into the packaging box through the hole, passing through the clearance groove 120 to reach the bottom of the fixing plate 100. The anti-detachment blocks 140 enter the strips 210 through the insertion port 240. At this point, the external force applied to the two sets of strips 210 can be removed. The curved elastic plastic strip 230 recovers its elasticity and pushes the two sets of strips 210 away from each other. Alternatively, a relative force can be manually applied to the two sets of strips 210 to move them away from each other. The L-shaped block 250 will adhere to the top of the anti-detachment block 140, as per the instruction manual. Figure 5 As shown, the rubber strip 252 also enters the groove 141. The chamfer 251 on its end face is designed to prevent the end of the anti-detachment block 140 from sticking up, making the anti-detachment block 140 and the L-shaped block 250 easy and efficient to engage. This can improve the bending strength of the anti-detachment block 140, so that the anti-detachment block 140 will not easily slip off the bottom of the fixing plate 100. The frame 210 can slide on the bottom of the fixing plate 100 with the bending of the handle strip 110, which can make it easy for the handle strip 110 to gradually come to a horizontal state, which can facilitate the stacking of packaging boxes.

[0018] Please refer to this carefully. Figure 2 , Figure 4 and Figure 6 Each set of frame 210 has a constraint strip 260 fixed on its front and rear surfaces, and the outer wall of the constraint strip 260 is slidably sleeved with an outer sleeve 150 fixed to the bottom of the fixing plate 100.

[0019] The cooperation between the outer jacket 150 and the constraint strip 260 allows the frame 210 to slide linearly at the bottom of the fixed plate 100.

[0020] Please refer to this carefully. Figure 2 The handle strip 110 and the anti-detachment block 140 are integrally injection molded.

[0021] The one-piece molding structure strengthens the connection between the two, allowing it to better support the weight of the items inside the packaging box.

[0022] In use, first place the fixing plate inside the top of the packaging box, aligning the clearance groove 120 with the hole on the packaging box. Simultaneously, apply relative external force to the two sets of bottom strips 210. The curved elastic plastic strip 230 deforms and generates a certain reverse force, aligning the middle of the insertion port 240 with the clearance groove 120. Next, insert the anti-detachment blocks 140 at both ends of the handle strip 110 into the packaging box through the hole, passing through the clearance groove 120 to reach the bottom of the fixing plate 100. The anti-detachment blocks 140 enter the strips 210 through the insertion port 240. At this point, the external force applied to the two sets of strips 210 can be removed. The curved elastic plastic strip 230 recovers its elasticity and pushes the two sets of strips 210 away from each other. Manually applying a force to move the two sets of strips 210 away from each other will cause the L-shaped block 250 to adhere to the top of the anti-detachment block 140, as per the instruction manual. Figure 5 As shown, the rubber strip 252 also enters the groove 141. The chamfer 251 on its end face is designed to prevent the anti-detachment block 140 from warping at the end, making the anti-detachment block 140 and the L-shaped block 250 easy and efficient to engage. This improves the bending strength of the anti-detachment block 140, preventing it from easily slipping off the bottom of the fixing plate 100. The frame 210 can slide on the bottom of the fixing plate 100 as the handle strip 110 bends, making it easier for the handle strip 110 to gradually become horizontal, which facilitates the stacking of packaging boxes. All parts not mentioned are the same as or can be implemented using existing technology.
