Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a walkie-talkie injection molded housing structure that is easy to assemble. Background Technology

[0002] In the production process of walkie-talkie housings, injection molds are required. Existing injection molds are usually installed using bolts during assembly, which requires the use of various types of installation wrenches and other tools, making the operation cumbersome and inconvenient.

[0003] A walkie-talkie injection-molded housing structure with publication number CN218488945U, belonging to the field of plastic mold technology, is disclosed. It includes an injection-molded housing mechanism comprising a mounting plate, a mold placed on top of the mounting plate, an injection groove on the top of the mold, four positioning rods on the top of the mold, and a positioning slot; an auxiliary positioning mechanism located on top of the mounting plate, which works in conjunction with the mold; and a limiting mechanism located on top of the mounting plate, which works in conjunction with the auxiliary positioning mechanism. This invention, by setting an auxiliary positioning mechanism, can achieve the purpose of assisting in the positioning of the mold, making the assembly process of the mold more convenient, and preventing misalignment after assembly, allowing the mold to be quickly assembled into the required position.

[0004] The aforementioned prior art uses the reaction force of a spring to move a movable plate during installation. The movement of the movable plate moves a limiting rod, which then enters the inner cavity of the limiting hole, thereby limiting the limiting plate and the mold. However, during assembly, the limiting rod needs to be pulled upwards at all times when the dovetail block is inserted into the dovetail groove. If the limiting rod pops out due to slippage or other errors, it will be stuck by the mounting plate when the dovetail block is inserted into the dovetail groove. This makes the assembly susceptible to slippage and other errors, resulting in a low assembly error tolerance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the ease with which assembly is affected by errors like hand slippage and the low tolerance for assembly errors, and to propose a walkie-talkie injection-molded housing structure that is easy to assemble.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a walkie-talkie injection molding housing structure that is easy to assemble, including a mounting plate and a mold. The top of the mold has a through hole, and a torsion bar is rotatably installed inside the through hole. A positioning component is installed at the upper end of the torsion bar, and a locking block is fixedly connected to the outer wall of the torsion bar. The mounting plate has an insertion hole on its top, a slot adapted to the card block on the side of the insertion hole, and a card groove adapted to the card block on the bottom of the insertion hole.

[0007] Furthermore, the positioning component includes a groove formed on the top of the mold, two positioning slots formed on the side wall of the groove, a knob fixedly connected to the top of the torsion bar, and a positioning block adapted to the positioning slots installed on the outer wall of the knob via a pop-out component.

[0008] Furthermore, the pop-out component includes a mounting groove formed on the outer wall of the knob, and a positioning block is inserted into the interior of the mounting groove through a limiting component. A spring piece is fixedly connected to one end of the positioning block located in the mounting groove, and the end of the spring piece away from the positioning block abuts against the inner wall of the mounting groove.

[0009] Furthermore, the limiting component includes a limiting groove formed on the top of the knob, a limiting post slidably installed inside the limiting groove, and a positioning block fixedly connected to the lower end of the limiting post.

[0010] Furthermore, an annular groove is formed at the bottom of the groove, a retaining ring is fixedly installed inside the annular groove, and a limiting ring located inside the annular groove is fixedly connected to the outer wall of the torsion bar, with the top of the limiting ring abutting against the retaining ring.

[0011] Furthermore, the top wall of the slot is chamfered.

[0012] The present invention proposes a walkie-talkie injection-molded housing structure that is easy to assemble. The advantages are as follows: When assembling this walkie-talkie injection-molded housing structure, the torsion bar is first inserted into the socket, and then the knob and the limiting post are pinched and rotated to allow the locking block to be inserted into the slot, thus completing the assembly of the mold and the mounting plate. This is more convenient and faster than using bolts for assembly. At the same time, as two assembly actions, inserting the torsion bar into the socket and pinching the knob and the limiting post and rotating them are performed separately and do not need to be performed continuously, which effectively reduces the difficulty of assembly and the error rate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 As an embodiment of this utility model, a walkie-talkie injection molding housing structure that is easy to assemble is disclosed, including a mounting plate 1 and a mold 2. The top of the mold 2 is provided with a through hole 21, and a torsion bar 3 is rotatably installed inside the through hole 21. A positioning component 4 is installed at the upper end of the torsion bar 3, and a locking block 5 is fixedly connected to the outer wall of the torsion bar 3. Preferably, a plurality of positioning posts are fixedly installed at the top of the mounting plate 1, and the upper ends of the positioning posts penetrate through and slide to connect with the mold 2. The top of the mold 2 is provided with an injection groove for injection molding the walkie-talkie housing. The top of the mounting plate 1 is provided with an insertion hole 6, the side of the insertion hole 6 is provided with a slot 61 that matches the card block 5, and the bottom of the insertion hole 6 is provided with a card groove 62 that matches the card block 5. During installation, mold 2 is placed on several positioning posts, and torsion bar 3 is inserted into insertion hole 6, so that locking block 5 is inserted into the bottom of slot 61. Then, torsion bar 3 is rotated so that locking block 5 is inserted into slot 62. Positioning component 4 positions torsion bar 3 to prevent it from rotating and drives locking block 5 to disengage from slot 62. Torsion bar 3, in conjunction with insertion hole 6, positions and guides mold 2, preventing it from moving or rotating in the plane. Locking block 5, in conjunction with slot 62, limits mold 2 in the vertical direction, thereby fixing mold 2 on mounting plate 1. This completes the assembly of mold 2 and mounting plate 1 into a walkie-talkie injection molded shell, so that it can be molded with moving mold to complete the injection molding of walkie-talkie shell.

[0017] Specifically, the positioning component 4 includes a groove 41 formed on the top of the mold 2, two positioning slots 42 formed on the side wall of the groove 41, a knob 43 fixedly connected to the top of the torsion bar 3, and a positioning block 44 adapted to the positioning slot 42 is installed on the outer wall of the knob 43 through the pop-out component 7. Preferably, the two positioning slots 42 are located above the slot 61 and the card slot 62, respectively. During disassembly, pinch the knob 43 to disengage the positioning block 44 from the positioning groove 42 above the slot 62, then rotate the torsion bar 3 to disengage the slot 5 from the slot 62 and enter the slot 61, aligning the positioning block 44 with the positioning groove 42 above the slot 61. Release the knob 43 to insert the positioning block 44 into the positioning groove 42 above the slot 61, and then lift it up to remove the mold 2. During assembly, insert the torsion bar 3 into the socket 6 and insert the locking block 5 into the slot 61. Then, pinch the knob 43 to disengage the positioning block 44 from the positioning groove 42 above the slot 61. Then, rotate the torsion bar 3 to disengage the locking block 5 from the slot 61 and into the slot 62, aligning the positioning block 44 with the positioning groove 42 above the slot 62. Release the knob 43 to insert the positioning block 44 into the positioning groove 42 above the slot 61.

[0018] Furthermore, the pop-out component 7 includes a mounting groove 71 formed on the outer wall of the knob 43. A positioning block 44 is inserted into the interior of the mounting groove 71 through a limiting component 8. A spring piece 72 is fixedly connected to one end of the positioning block 44 located in the mounting groove 71, and the end of the spring piece 72 away from the positioning block 44 abuts against the inner wall of the mounting groove 71. The positioning block 44 is pushed outward by the spring piece 72 so that it is automatically inserted into the positioning slot 42 when it is aligned with the positioning slot 42.

[0019] Furthermore, the limiting component 8 includes a limiting groove 81 formed on the top of the knob 43, a limiting post 82 is slidably installed inside the limiting groove 81, and the lower end of the limiting post 82 is fixedly connected to the positioning block 44. The positioning block 44 is positioned by the limiting post 82 in conjunction with the limiting groove 81 to prevent it from falling out of the mounting groove 71. At the same time, by pinching the knob 43, the limiting post 82 can be pinched to bring it close to the center of the knob and drive the positioning block 44 to move inward and fall out of the positioning groove 42.

[0020] It should be noted that an annular groove 9 is provided at the bottom of the groove 41, and a retaining ring 10 is fixedly installed inside the annular groove 9. A limiting ring 11 located inside the annular groove 9 is fixedly connected to the outer wall of the torsion bar 3, and the top of the limiting ring 11 abuts against the retaining ring 10. The retaining ring 10 presses the limiting ring 11 into the ring groove 9, so that it can only rotate within the ring groove 9 and cannot move up and down, thereby rotating the torsion rod 3 into the through hole 21.

[0021] In some embodiments, a chamfer is formed on the top wall of the card slot 62. By forming a chamfer on the top wall of the card slot 62, it is easier for the card block 5 to be inserted into the card slot 62.

[0022] Working method: When disassembling, pinch the knob 43 and the limiting post 82 to make the positioning block 44 disengage from the positioning groove 42 above the slot 62, then rotate the torsion bar 3 to make the block 5 disengage from the slot 62 and enter the slot 61, and make the positioning block 44 aligned with the positioning groove 42 above the slot 61. Release the knob 43 so that the positioning block 44 can be inserted into the positioning groove 42 above the slot 61 under the action of the spring piece 72, and the mold 2 can be lifted up directly to remove it. During assembly, insert the torsion bar 3 into the socket 6 and insert the locking block 5 into the slot 61. Then, pinch the knob 43 and the limiting post 82 to disengage the positioning block 44 from the positioning groove 42 above the slot 61. Then, rotate the torsion bar 3 to disengage the locking block 5 from the slot 61 and insert it into the slot 62, aligning the positioning block 44 with the positioning groove 42 above the slot 62. Release the knob 43 to insert the positioning block 44 into the positioning groove 42 above the slot 61, thus completing the assembly of the mold 2 and the mounting plate 1.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
