Description

Technical Field

[0001] This utility model relates to the field of plastic handle technology, specifically a modular plastic handle. Background Technology

[0002] Traditional plastic handles consist of a handle with connecting parts at both ends and a fixing plate that fit together and are installed on the packaging box. The fixing plate is placed inside the cardboard packaging box, and then the fixing plate and handle are assembled through the handle holes opened on the packaging box. Only through the combination of the handle and the fixing plate can the expected use effect be achieved.

[0003] However, due to factors such as packaging or stacking of plastic handles, the connecting parts at both ends are in a relatively horizontal state with the handle. When the handle and the fixing plate are installed together, the connecting arms at both ends will go straight in and out and cannot complete the interlocking effect. It is necessary to manually operate on the inside and outside of the packaging box with both hands, which results in an angle between the connecting part and the handle, making the installation of the handle time-consuming. Therefore, a modular plastic handle is proposed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a modular plastic handle to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined plastic handle, including a bottom strip, a handle strip above the bottom strip, both ends of the handle strip extending to the bottom of the bottom strip and connected to load-bearing end pieces, two sets of rectangular grooves being formed on the end face of the load-bearing end piece near the handle strip, an extension piece being connected in each set of rectangular grooves, and an elastic arc strip that abuts against the lower surface of the handle strip being glued to the top of the two sets of extension pieces.

[0006] As a preferred technical solution, the rectangular groove is provided with a connecting piece connected to the outer wall of the extension piece, and the connecting piece is fixed to the extension piece and the rectangular groove by adhesive.

[0007] As a preferred technical solution, the side of the front and rear surfaces of the extension piece near the load-bearing end piece is inclined.

[0008] As a preferred technical solution, the upper surface of the extension piece is flush with the top of the load-bearing end piece, and the width dimension formed by the two sets of extension pieces and load-bearing end pieces is greater than the length dimension of the clearance groove.

[0009] As a preferred technical solution, the front and rear surfaces of the handle strip are both chamfered at the external corners.

[0010] As a preferred technical solution, the end of the load-bearing end piece away from the handle strip is provided with an arc end, and the load-bearing end piece and the handle strip are integrally injection molded.

[0011] In summary, the present invention has the following main advantages:

[0012] This invention increases the width of the load-bearing end piece by extending it, allowing it to slide securely at the bottom of the base strip. This effectively prevents the base strip and handle strip from separating. At the same time, the elastic strip provides some restraint to the two sets of extension pieces and can enter the relief groove as the handle strip bends, keeping the handle strip in a centrally convex state, thus facilitating manual gripping of the handle strip.

[0018] 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.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] A type of modular plastic handle, such as Figures 1 to 4 As shown, it includes a bottom strip 100, and a handle strip 110 is provided above the bottom strip 100. Both ends of the handle strip 110 extend to the bottom of the bottom strip 100 and are connected to load-bearing end pieces 120. The end face of the load-bearing end piece 120 near the handle strip 110 is provided with two sets of rectangular grooves 122. Each set of rectangular grooves 122 is connected to an extension piece 140. The top of the two sets of extension pieces 140 is glued with an elastic arc strip 160 that abuts against the lower surface of the handle strip 110.

[0021] The upper surface of the extension piece 140 is flush with the top of the load-bearing end piece 120, and the width of the two sets of extension pieces 140 and the load-bearing end piece 120 is greater than the length of the relief groove 130.

[0022] Place the bottom strip 100 inside the packaging box and apply an external force to the load-bearing end piece 120 near the handle strip 110. At this time, extend the load-bearing end pieces 120 at both ends of the handle strip 110 into the relief groove 130 from the outside of the packaging box. The load-bearing end pieces 120 will pass through the pre-reserved groove on the packaging box until the load-bearing end pieces 120 are completely through the relief groove 130, so that the load-bearing end pieces 120 no longer have an external force on the side near the handle strip 110. Its elastic arc strip 160 returns to its original state, and the two sets of extension pieces 140 also return to their original state, as per the instruction manual. Figure 2 and Figure 3 As shown, the dimensions formed by the two sets of extension plates 140 and the load-bearing end plates 120 are larger than the relief groove 130, ensuring that the load-bearing end plates 120 always slide at the bottom of the bottom strip 100. This prevents the load-bearing end plates 120 from falling off as they pass through the relief groove 130, ensuring a secure connection between the handle strip 110 and the bottom strip 100. Simultaneously, the elastic arc strip 160 will also enter the relief groove 130 when the handle strip 110 is pulled upwards by the hand, as shown in the instruction manual. Figure 4 As shown, the handle strip 110 can be kept in a centrally arched state, which makes it easy for the hand to quickly grip the outside of the handle strip 110.

[0023] Please refer to this carefully. Figure 2 and Figure 3 The rectangular groove 122 is provided with a connecting piece 150 connected to the outer wall of the extension piece 140. The connecting piece 150 is fixed to the extension piece 140 and the rectangular groove 122 by adhesive.

[0024] The thinner connecting piece 150 serves as a constraint, allowing the extension piece 140 to rotate smoothly. At the same time, it facilitates the rotation of the extension piece 140 and allows it to tilt and lie flat on the upper surface of the load-bearing end piece 120.

[0025] Please refer to this carefully. Figure 2 and Figure 3 The front and rear surfaces of the extension piece 140 near the load-bearing end piece 120 are inclined.

[0026] This causes the two sets of extension plates 140 to rotate inward and be placed at an angle on top of the load-bearing end plate 120, without contacting the handle strip 110, thus allowing them to pass easily through the clearance groove 130 inside the load-bearing end plate 120.

[0027] Please refer to this carefully. Figure 1 and Figure 2 The front and rear surfaces of the handle strip 110 are both chamfered at the external corners.

[0028] It can reduce the marks on the palm of the hand, making it more comfortable to grip the handle strip 110.

[0029] Please refer to this carefully. Figure 2 and Figure 3 The end of the load-bearing end piece 120 away from the handle strip 110 is provided with an arc end 121, and the load-bearing end piece 120 and the handle strip 110 are integrally injection molded.

[0030] The arc end 121 allows the load-bearing end piece 120 to quickly and accurately extend into the relief groove 130, making the connection between the handle strip 110 and the bottom strip 100 efficient. At the same time, the one-piece injection molding can increase the strength between the load-bearing end piece 120 and the handle strip 110, and better withstand external forces (external forces refer to the weight of the items stored inside the packaging box).

[0031] In use, place the bottom strip 100 inside the packaging box and apply external force to the load-bearing end piece 120 near the handle strip 110. At this time, extend the load-bearing end pieces 120 at both ends of the handle strip 110 into the relief groove 130 from the outside of the packaging box. The load-bearing end pieces 120 will pass through the grooves reserved on the packaging box until the load-bearing end pieces 120 are completely through the relief groove 130, so that the load-bearing end pieces 120 no longer have external force on the side near the handle strip 110. The elastic arc strip 160 returns to its original state, and the two sets of extension pieces 140 also return to their original state, as per the instruction manual. Figure 2 and Figure 3 As shown, the dimensions formed by the two sets of extension plates 140 and the load-bearing end plates 120 are larger than the relief groove 130, ensuring that the load-bearing end plates 120 always slide at the bottom of the bottom strip 100. This prevents the load-bearing end plates 120 from falling off as they pass through the relief groove 130, ensuring a secure connection between the handle strip 110 and the bottom strip 100. Simultaneously, the elastic arc strip 160 will also enter the relief groove 130 when the handle strip 110 is pulled upwards by the hand, as shown in the instruction manual. Figure 4 As shown, the handle strip 110 can be kept in a centrally arched state, which makes it convenient for the hand to quickly grip the outside of the handle strip 110. The parts not shown are the same as or can be implemented using existing technology.
