Description

Technical Field

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

[0002] To facilitate carrying or handling of packaging boxes (especially paper boxes), handle holes are usually provided on the boxes for assembling handle structures. This allows the carrier or mover to hold the handle structure to carry or move the goods, greatly reducing physical exertion during the carrying and handling process, making it convenient and quick, and effectively protecting the goods.

[0003] Traditional plastic handles consist of a handle part and a fixing strip that work together to be installed on the packaging box. The fixing strip is placed inside the cardboard packaging box, and then the fixing strip and the handle part are assembled through the handle hole opened on the packaging box. Only through the combination of the handle part and the fixing strip can the expected use effect be achieved.

[0004] Current plastic handles have the following drawbacks in practical use:

[0005] 1. When the packaging box is placed on the ground, the handle cannot be fixed in shape without external force, making it inconvenient to grip the outside of the handle;

[0006] 2. The weight of the items inside the packaging box exerts a downward pull on the fixing strip, which can cause the two ends of the handle to separate from the fixing strip, resulting in the packaging box falling to the ground. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a packaging box handle suitable for storage, so as to solve the technical problems mentioned in the background.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a packaging box handle suitable for storage, comprising a fixing strip and a handle portion, wherein both ends of the handle portion are fixed with a load-bearing portion extending to the bottom of the fixing strip, and the top of the fixing strip near both ends is provided with a clearance groove adapted to the width of the handle portion;

[0009] The inner wall of each set of clearance grooves is fixed with two sets of trapezoidal blocks extending into the handle. The handle has a snap-fit ​​groove at the contact position with the trapezoidal blocks. The top of each set of load-bearing parts is glued with two sets of flexible plastic strips on both sides of the handle. The lower surface of the fixing strip and the position corresponding to the flexible plastic strip are reserved with grooves.

[0010] As a preferred technical solution, each set of trapezoidal blocks and fixing strips is integrally injection molded using a mold.

[0011] As a preferred technical solution, a constraint plate is glued to the bottom of the fixing strip near the center of the relief groove, one end of the load-bearing part extends into the constraint plate, and the constraint plate is reserved with a limiting groove to prevent the load-bearing part from completely detaching.

[0012] As a preferred technical solution, the left and right ends of the load-bearing part are provided with arc-shaped chamfers.

[0013] As a preferred technical solution, the trapezoidal block has a trapezoidal shape in both top and side views.

[0014] As a preferred technical solution, the front and rear surfaces of the handle are provided with rounded chamfers at the external corners.

[0015] In summary, the present invention has the following main advantages:

[0016] This invention increases the stability of the connection between the handle and the fixing strip by setting trapezoidal blocks, better preventing the packaging box from falling off. In addition, the combination of flexible plastic strips and grooves increases the coefficient of friction between the load-bearing part and the fixing strip, making the handle, which is arched in the middle, stable and easy for people to quickly grip the handle to carry the packaging box.

[0023] 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.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A type of packaging box handle suitable for storage, such as Figures 1 to 5 As shown, it includes a fixing strip 100 and a handle 110. Both ends of the handle 110 are fixed with a load-bearing part 120 that extends through to the bottom of the fixing strip 100. The top of the fixing strip 100 near both ends is provided with a relief groove 140 that matches the width of the handle 110.

[0026] The inner wall of each set of clearance grooves 140 is fixed with two sets of trapezoidal blocks 150 extending into the handle part 110. The handle part 110 is provided with a buckle groove 130 at the contact position with the trapezoidal block 150. The top of each set of load-bearing parts 120 is glued with two sets of flexible plastic strips 121 on both sides of the handle part 110. The lower surface of the fixing strip 100 is reserved with a groove 170 at the position corresponding to the flexible plastic strip 121.

[0027] The bottom of the fixing strip 100 is located in the relief groove 140 near the center of the fixing strip 100, and a constraint plate 160 is glued thereon. One end of the load-bearing part 120 extends into the constraint plate 160, and the constraint plate 160 is reserved with a restriction groove 161 to prevent the load-bearing part 120 from completely falling out.

[0028] Place the fixing strip 100 inside the top of the packaging box. (It is worth noting that the load-bearing part 120 and the handle part 110 can swing around the connection point so that the two are in a state of mutual contact.) You can manually apply external force to the load-bearing part 120 to make it fit against the bottom of the handle part 110. At this time, the load-bearing parts 120 at both ends of the handle part 110 can be inserted into the grooves reserved in the packaging box. The load-bearing parts 120 will continue to lower into the relief groove 140 until they pass through the relief groove 140 and return to their original position, so that the handle is installed on the packaging box.

[0029] When lifting the box, place your fingers under the handle 110 in a fist shape, apply downward pressure to the box with your other hand, and apply upward pull with the hand gripping the handle 110. The handle 110 will arch in the middle, as shown in the instruction manual. Figure 1 As shown, at this time, the two load-bearing parts 120 at both ends of the handle 110 will move towards the center and one end will enter the limiting groove 161, so that the load-bearing part 120 is in a horizontal state and fits against the lower surface of the fixing strip 100. The flexible plastic strip 121 is squeezed and deformed by the lower part of the fixing strip 100 as the load-bearing part 120 moves until it enters the strip groove 170. At this time, the trapezoidal block 150 also enters the buckle groove 130, which can limit the handle 110 and prevent it from slipping and falling off. Even when the packaging box is placed on the ground, the handle 110 can remain in the middle arched state, which makes it convenient for people to hold the handle 110 to carry the packaging box next time.

[0030] Please refer to this carefully. Figure 2 Each trapezoidal block 150 and the fixing strip 100 are integrally injection molded using a mold;

[0031] The trapezoidal block 150 has a trapezoidal cross-section in both top and side views.

[0032] This allows the trapezoidal block 150 connected in the relief groove 140 to better withstand external forces, enabling the trapezoidal block 150 to limit the handle part 110 and prevent slippage and detachment.

[0033] Please refer to this carefully. Figure 2 and Figure 4 The left and right ends of the load-bearing part 120 are provided with arc-shaped chamfers.

[0034] By making the end dimension of the load-bearing part 120 smaller than that of the relief groove 140, the load-bearing parts 120 at both ends of the handle part 110 can quickly enter the relief groove 140.

[0035] Please refer to this carefully. Figure 2 and Figure 4 The front and rear surfaces of the handle 110 are both chamfered.

[0036] It can alleviate the marks caused by the handle, thus making it more comfortable to grip the handle 110.

[0037] When using, place your fingers under the handle 110 in a fist shape, apply downward pressure to the packaging box with your other hand, and apply upward pulling force with the hand gripping the handle 110. The handle 110 will arch in the middle, as shown in the instruction manual. Figure 1 As shown, at this time, the two load-bearing parts 120 at both ends of the handle 110 will move towards the center and one end will enter the limiting groove 161, so that the load-bearing part 120 is in a horizontal state and fits against the lower surface of the fixing strip 100. The flexible plastic strip 121 is squeezed and deformed by the lower part of the fixing strip 100 as the load-bearing part 120 moves until it enters the strip groove 170. At this time, the trapezoidal block 150 also enters the buckle groove 130, which can limit the handle 110 and prevent slippage and detachment. Even when the packaging box is placed on the ground, the handle 110 can remain in the middle arched state, which makes it convenient for people to hold the handle 110 to carry the packaging box next time. The parts not involved in this device are the same as the prior art or can be implemented by the prior art.
