Description

Technical Field

[0001] This utility model relates to the field of plastic handle technology, and more specifically, to an anti-loosening plastic handle. Background Technology

[0002] Plastic handles are lightweight and durable packaging accessories, usually injection molded from materials such as polyethylene (PE) or polypropylene (PP), and are widely used in packaging containers such as beverage boxes, food boxes, and gift bags.

[0003] A search revealed CN220010597U, which discloses an anti-loosening plastic handle, comprising a handle body and an mounting frame. The handle body is mounted on the mounting frame, and there are two mounting frames. Each mounting frame has a through groove. The bottom end of each handle body extends to the outer surface of the mounting frame through the through groove. The handle body has multiple first engaging grooves, and each first engaging groove has a first engaging block engaged inside. The sides of each handle body that are far apart from each other are fixedly mounted with outer abutment plates. The double anti-loosening structure can prevent loosening from occurring.

[0004] However, although the above technical solution achieves the limiting and fixing of the handle body and the mounting frame through the double anti-loosening structure, it still has certain limitations in practical applications. Specifically, since the anti-loosening components such as the locking block and the outer abutment plate are fixedly connected to the handle, it is difficult to quickly disassemble and replace the handle when it is damaged, thus affecting the maintainability and ease of use of the overall structure. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-loosening plastic handle to solve the problem that some anti-loosening plastic handles in the prior art adopt a double limiting structure, but the locking block and other components are fixedly connected, which makes it difficult to replace after damage, affecting the flexibility of use and the convenience of maintenance.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-loosening plastic handle, comprising...

[0007] The plastic handle body has an expansion frame on the outer surface of both ends. A connector post is fixedly installed on the surface of the bottom end of each of the two expansion frames that are close to each other. A limit strip is fixedly installed on the inner surface of the connector post, and two parallel movable blocks are slidably installed on the inner surface of the connector post. The outer edges of the two movable blocks are slidably installed with the outer surface of the limit strip. A snap-fit ​​block is fixedly installed on the side end of each of the two movable blocks. The two snap-fit ​​blocks are symmetrically arranged. A bidirectional threaded rod is threadedly connected to the middle of the two movable blocks. The outer surfaces of both ends of the bidirectional threaded rod are rotatably installed with the inner surface of the connector post, and an adjustment knob is fixedly installed on the surface of both ends.

[0008] The mounting frame is sleeved on the end of the connector post near the snap-fit ​​block one.

[0009] The mounting frame has a limit ring fixedly installed on its inner surface. The two locking blocks are provided with grooves at their far ends. The outer surface of the locking block is rotatably installed with the inner surface of the mounting frame. The groove is rotatably installed with the outer surface of the limit ring. The outer surface of the connector post is provided with an auxiliary stabilizing mechanism.

[0010] The auxiliary stabilizing mechanism includes a ring frame and a fixing block. The side edge of the ring frame is fixedly installed on the surface of the mounting frame near the joint column. The lower surface of the fixing block is fixedly installed on the outer surface of the joint column. A protruding post is slidably sleeved on the inner surface of the top of the fixing block. A spring is provided inside the fixing block. One end of the spring is fixedly connected to the inner wall of the fixing block, and the other end is fixedly connected to the surface of the protruding post. The end of the protruding post away from the spring is engaged with multiple spherical grooves opened in the middle of the ring frame.

[0011] The plastic handle body has a housing fixedly mounted on its lower surface. A movable rod is movably sleeved in the middle of the housing. A collar is movably sleeved on the outer surface of the movable rod. Two locking blocks are slidably sleeved on both sides of the housing in the width direction. The two locking blocks are symmetrically arranged. A connecting rod is hinged to the upper and lower surfaces of the two locking blocks. The end of the connecting rod away from the locking block is hinged to the surface of the collar. A spring is fixedly connected to the side of the collar away from the locking block. The spring is sleeved on the outside of the movable rod, and the end away from the collar is fixedly connected to the inner wall of the side of the housing.

[0012] A magnetic absorbing plate is fixedly installed on the inner wall of the housing on the side away from the second spring. An iron plate is fixedly installed on the end of the movable rod near the magnetic absorbing plate. The iron plate and the middle of the magnetic absorbing plate are detachably installed. Several insertion slots are opened on both sides of the expansion frame. The inner surface of the insertion slot is engaged with the end of the second snap-fit ​​block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, by setting up a mounting frame, connector post, and other structures, in actual use, first rotate the adjustment knob on the outside of the connector post, causing the connected bidirectional threaded rod to rotate against the inner wall of the connector post. The two movable blocks threaded to the outer surface of the bidirectional threaded rod will slide along the inner wall of the connector post and the outer surface of the limiting strip, and move closer to each other until the surfaces of the two blocks that are close to each other are in contact. At this time, the two locking blocks connected to the ends of the movable blocks are also in contact with each other. Then, insert the connector post into the mounting frame until the locking blocks move away from the movable blocks. After the side of the moving block abuts against the inner wall of the mounting frame, the double-threaded rod is rotated again by adjusting the knob, causing the moving block and the connected snap-fit ​​block 1 to move away from each other. Finally, the outer edge of snap-fit ​​block 1 will abut against the inner surface of the mounting frame. At this time, the snap-fit ​​block 1 in the unfolded state will limit the joint post and connect the joint post to the mounting frame. Thus, the joint post and the mounting frame are snapped together using the snap-fit ​​block 1 and other structures, which facilitates disassembly. In addition, the threaded connection between the double-threaded rod and the moving block can improve stability and enhance the anti-detachment effect.

[0015] In the above scheme, by setting up structures such as a movable rod and a second locking block, when adjustment is needed, the movable rod can be pulled outwards. When the movable rod is pulled out, the iron plate installed at its end will push the collar sleeved on the outside of the movable rod to move and squeeze the connected spring. As the collar moves, the hinged connecting rod will pull the second locking block connected to the other end to move along the inner walls on both sides of the shell into the interior of the shell until the second locking block moves out of the insertion groove opened on the surface of the expansion frame. At this time, the plastic handle body and the expansion frame are unlocked, and the position of the plastic handle body can be adjusted by moving it up and down. Thus, the extension and retraction state of the second locking block can be adjusted by using the movable rod and other structures, thereby adjusting the connection state between the plastic handle body and the expansion frame, which facilitates the adjustment of the position of the plastic handle body.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides an anti-loosening plastic handle, including...

[0025] The plastic handle body 1 has an extension frame 2 on the outer surface of both ends. The bottom ends of the two extension frames 2 are close to each other and the surface of the two extension frames 2 are fixedly installed with a connector post 4. The inner surface of the connector post 4 is fixedly installed with a limit strip 5. Two parallel movable blocks 6 are slidably installed on the inner surface of the connector post 4. The outer edges of the two movable blocks 6 are slidably installed with the outer surface of the limit strip 5. The side ends of the two movable blocks 6 are fixedly installed with a snap-fit ​​block 9. The two snap-fit ​​blocks 9 are symmetrically arranged. The middle of the two movable blocks 6 is threadedly connected with a bidirectional threaded rod 7. The outer surfaces of both ends of the bidirectional threaded rod 7 are rotatably installed with the inner surface of the connector post 4. The surfaces of both ends are fixedly installed with an adjustment knob 8.

[0026] By setting the limiting strip 5 and the limiting ring 11, when the movable block 6 slides against the inner wall of the connector post 4, it will also slide along the outer surface of the limiting strip 5. The limiting strip 5 limits the movable block 6 in the inner cavity of the connector post 4. In addition, when the snap-fit ​​block 9 unfolds to abut against the inner wall of the mounting frame 3, the groove 10 opened on the snap-fit ​​block 9 will fit against the outer surface of the limiting ring 11, providing further limiting treatment for the connection between the snap-fit ​​block 9 and the mounting frame 3.

[0027] Mounting frame 3 is fitted onto the end of connector post 4 near snap-fit ​​block 9.

[0028] Among them, a limit ring 11 is fixedly installed on the inner surface of the mounting frame 3, and grooves 10 are provided at the ends of the two locking blocks 9 that are far apart from each other. The outer surface of the locking block 9 is rotatably installed with the inner surface of the mounting frame 3, and the grooves 10 are rotatably installed with the outer surface of the limit ring 11. An auxiliary stabilizing mechanism 12 is provided on the outer surface of the connector post 4.

[0029] The auxiliary stabilizing mechanism 12 includes a ring frame 120 and a fixing block 121. The side edge of the ring frame 120 is fixedly installed on the surface of the mounting frame 3 near the joint column 4. The lower surface of the fixing block 121 is fixedly installed on the outer surface of the joint column 4. A protruding column 123 is slidably sleeved on the inner surface of the top of the fixing block 121. A spring 122 is provided inside the fixing block 121. One end of the spring 122 is fixedly connected to the inner wall of the fixing block 121, and the other end is fixedly connected to the surface of the protruding column 123. The end of the protruding column 123 away from the spring 122 is engaged with multiple spherical grooves opened in the middle of the ring frame 120.

[0030] By setting the auxiliary stabilizing mechanism 12, after the connector column 4 and the mounting frame 3 are installed, the outer surface of the end of the connector column 4 and the outer surface of the connecting snap block 9 can both rotate against the inner wall of the mounting frame 3, realizing the free steering adjustment of the plastic handle body 1. During the rotation of the connector column 4, the fixing block 121 connected to its outer surface and the protrusion 123 sleeved inside the fixing block 121 will move accordingly. The end of the protrusion 123 will move along the middle of the annular frame 120 on the surface of the fixed mounting frame 3. Due to the elastic force provided by the spring 122, when the protrusion 123 moves to the spherical groove opened inside the annular frame 120, it will push the protrusion 123 to snap into the spherical groove. Therefore, the plastic handle body 1, under non-external force, uses the snapping state of the protrusion 123 and the annular frame 120 to provide a locking effect on the rotation of the plastic handle body 1, preventing the plastic handle body 1 and other structures in a stationary state from suddenly tipping over under the action of gravity or external impact.

[0031] The lower surface of the plastic handle body 1 is fixedly installed with a housing 13. A movable rod 14 is movably sleeved in the middle of the housing 13. A collar 15 is movably sleeved on the outer surface of the movable rod 14. Two locking blocks 17 are slidably sleeved on both sides of the housing 13 in the width direction. The two locking blocks 17 are symmetrically arranged. A connecting rod 16 is hinged to the upper and lower surfaces of the two locking blocks 17. The end of the connecting rod 16 away from the locking block 17 is hinged to the surface of the collar 15. A spring 18 is fixedly connected to the side of the collar 15 away from the locking block 17. The spring 18 is sleeved on the outside of the movable rod 14, and the end away from the collar 15 is fixedly connected to the inner wall of the side of the housing 13.

[0032] Among them, a magnetic absorbing piece 20 is fixedly installed on the inner wall of the side of the housing 13 away from the second spring 18, and an iron piece 19 is fixedly installed on the end of the movable rod 14 near the magnetic absorbing piece 20. The iron piece 19 and the middle part of the magnetic absorbing piece 20 are detachably installed. Several insertion slots 21 are opened on both sides of the expansion frame 2. The inner surface of the insertion slot 21 is engaged with the end of the second snap-fit ​​block 17.

[0033] The working process of this utility model is as follows:

[0034] In actual use, first rotate the adjusting knob 8 on the outside of the connector post 4 to drive the connected bidirectional threaded rod 7 to rotate against the inner wall of the connector post 4. The two movable blocks 6 threaded to the outer surface of the bidirectional threaded rod 7 will slide along the inner wall of the connector post 4 and the outer surface of the limiting strip 5, and move closer to each other until the surfaces of the two sides that are close to each other are in contact. At this time, the two locking blocks 9 connected to the ends of the movable blocks 6 are also in contact with each other. Then, insert the connector post 4 into the interior of the mounting frame 3 until the side of the locking block 9 away from the movable block 6 abuts against the inner wall of the mounting frame 3. Then, adjust the bidirectional threaded rod 7 to rotate again by adjusting the adjusting knob 8, so that the movable block 6 and the connected locking block 9 move away from each other. Finally, the outer edge of the locking block 9 will abut against the inner surface of the mounting frame 3. At this time, the locking block 9 in the unfolded state will limit the connector post 4 and connect the connector post 4 to the mounting frame 3.

[0035] When using the plastic handle body 1, the locking and unlocking states of the movable rod 14 and other structures inside the housing 13 installed at its bottom can be adjusted to achieve the effect of lifting and lowering the plastic handle body 1 along the interior of the expansion frame 2, thus adjusting the actual height of the plastic handle body 1 during use. Specifically, when adjustment is required, the movable rod 14 can be pulled outward. When the movable rod 14 is pulled out, the iron plate 19 installed at its end will push the collar 15 sleeved on the outside of the movable rod 14 to move and squeeze the connected spring 18. As the collar 15 moves, the hinged connecting rod 16 will pull the locking block 17 connected at the other end to move along the inner walls on both sides of the housing 13 into the interior of the housing 13 until the locking block 17 moves out of the insertion groove 21 opened on the surface of the expansion frame 2. At this time, the plastic handle body 1 and the expansion frame 2 are unlocked, and the position of the plastic handle body 1 can be adjusted by moving it up and down.
