Description

Technical Field

[0001] This utility model relates to the field of packing straps, and specifically to a packing strap that is easy to connect. Background Technology

[0002] Packing straps are used to bind and secure the boxes during the sealing process to ensure their stability during transportation. Using packing straps can also reduce overall packaging costs and environmental pollution.

[0003] The existing packing straps still have the following problems when used: When connecting the beginning and end of the packing straps, knots are usually used. However, manual knotting cannot guarantee a strong connection, and it is inconvenient to untie them later.

[0004] Therefore, it is necessary to invent a packing strap that is easy to connect to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a packing strap that is easy to connect, in order to solve the problem mentioned in the background art that when using existing packing straps, the beginning and end sections of the packing strap are usually connected by knotting. Manual knotting cannot guarantee the strong connection of the packing strap, and it is also inconvenient to untie it later.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packing strap for easy connection, comprising a packing strap wrapped around the outside of a box, with connecting holes provided on both sides of the packing strap, and a lower connecting plate movably installed outside the connecting holes. A connecting rod is fixedly installed on the top of the lower connecting plate, the connecting rod passes through the connecting holes, and the upper end of the connecting rod matches a pre-reserved connecting groove inside the upper connecting plate. A channel is provided inside the upper connecting plate, the channel communicating with the connecting groove, and a locking rod is movably connected inside the channel via a spring, and the locking rod matches a pre-reserved locking groove inside the connecting rod. A threaded groove is pre-reserved inside the upper connecting plate, and a threaded rod is threadedly connected inside the threaded groove. The package also includes:

[0007] The anti-detachment component has a threaded groove connected to an annular groove, and an annular block is rotatably connected inside the annular groove. A limiting rod is fixedly connected to the inner wall of the annular block. The limiting rod is slidably connected to the limiting groove reserved inside the threaded rod to ensure that the connection between the threaded rod and the threaded groove does not fall off.

[0008] Preferably, the connecting holes are distributed linearly at equal intervals on the packing strap.

[0009] Preferably, the channel is provided in two places, and each channel is internally connected to two symmetrically arranged locking rods. The ends of the two locking rods located inside the channel are movably connected by a spring to ensure the movement of the locking rods located inside the channel and subsequent reset movement.

[0010] Preferably, the ends of the two clamping rods located in the groove are fixedly connected with pull ropes, and the two pull ropes inside one groove are wound together into one, and the upper end of the pull rope extends through into the threaded groove and is fixedly connected to the lower end of the threaded rod. In this way, when the threaded rod is rotated, the pull rope can be pulled to move, so that the pull rope pulls the clamping rod to achieve the matching and separation of the clamping rod and the clamping groove.

[0011] Preferably, the top and bottom of the limiting groove are both closed ends, and the inner wall of the limiting groove is attached to the outer wall of the limiting rod to achieve a sliding connection between the upper and lower parts, ensuring that the connection between the threaded rod and the threaded groove does not fall off and does not affect the rotation of the threaded rod.

[0012] Preferably, the top of the threaded rod has two symmetrically arranged arc-shaped cavities, and the arc-shaped cavities are connected to the limiting groove, which facilitates the subsequent manipulation of the threaded rod through the cavities.

[0013] In the above technical solution, the technical effects and advantages provided by this utility model are as follows: This utility model matches the pre-reserved connecting groove inside the upper connecting plate with the upper end of the connecting rod passing through the connecting hole, and twists the threaded rod. The reset rotation of the threaded rod causes the pull rope fixedly connected to the lower end of the threaded rod to unwind. At this time, the spring reset movement pushes the locking rod to match the locking groove pre-reserved inside the connecting rod. At this time, the upper and lower connecting plates are installed, and the front and rear ends of the packing strap are connected. This allows the packing strap to be reused later, and the operation is more environmentally friendly.

[0014] Furthermore, the anti-loosening component ensures that the threaded connection between the threaded rod and the threaded groove will not come off, and will not affect the rotation of the threaded rod inside the threaded groove. Attached Figure Description

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-4 The diagram shows a type of easy-to-connect packing strap, including a packing strap 1 wrapped around the outside of a box body 3. Connecting holes 2 are provided on both sides of the packing strap 1, and a lower connecting plate 4 is movably installed outside the connecting holes 2. A connecting rod 6 is fixedly installed on the top of the lower connecting plate 4, passing through the connecting holes 2. The upper end of the connecting rod 6 matches a pre-reserved connecting groove 7 inside an upper connecting plate 5. A channel 8 is provided inside the upper connecting plate 5, communicating with the connecting groove 7. A locking rod 9 is movably connected inside the channel 8 via a spring 10, and the locking rod 9 matches a pre-reserved locking groove 15 inside the connecting rod 6. A threaded groove 12 is pre-reserved inside the upper connecting plate 5, and a threaded rod 13 is threadedly connected inside the threaded groove 12. The diagram also includes:

[0024] The anti-detachment component 14 has a threaded groove 12 connected to an annular groove 1402, and an annular block 1401 is rotatably connected inside the annular groove 1402. A limiting rod 1403 is fixedly connected to the inner wall of the annular block 1401. The limiting rod 1403 is slidably connected to the limiting groove 1404 reserved inside the threaded rod 13 to ensure that the connection between the threaded rod 13 and the threaded groove 12 does not fall off.

[0025] The connecting holes 2 are evenly spaced in a linear pattern on the packing strap 1 to ensure that the connecting rods 6 on the lower connecting plate 4 are smoothly matched with the corresponding connecting holes 2.

[0026] There are two channels 8, and each channel 8 is internally connected to two symmetrically arranged locking rods 9. The ends of the two locking rods 9 inside the channel 8 are connected by a spring 10 to ensure the movement of the locking rods 9 inside the channel 8 and subsequent reset movement.

[0027] Both ends of the two levers 9 located in the channel 8 are fixedly connected to pull ropes 11, and the two pull ropes 11 inside one channel 8 are wound together into one, and the upper end of the pull rope 11 extends through to the inside of the threaded groove 12 and is fixedly connected to the lower end of the threaded rod 13. In this way, when the threaded rod 13 is rotated, the pull rope 11 can be pulled to move, so that the pull rope 11 pulls the lever 9 to move, thereby realizing the matching and separation of the lever 9 and the groove 15.

[0028] The top and bottom of the limiting groove 1404 are closed ends, and the inner wall of the limiting groove 1404 is attached to the outer wall of the limiting rod 1403 to achieve a sliding connection between the upper and lower parts, ensuring that the connection between the threaded rod 13 and the threaded groove 12 does not fall off and does not affect the rotation of the threaded rod 13.

[0029] The top of the threaded rod 13 has two symmetrically arranged arc-shaped cavities 16, and the arc-shaped cavities 16 are connected to the limiting groove 1404, so as to facilitate the subsequent manipulation of the threaded rod 13 through the cavities 16.

[0030] Working principle: When using a packing strap that is easy to connect, first confirm whether the clamping rod 9 is completely inside the channel 8. If the front end of the clamping rod 9 is inside the connecting groove 7, twist the threaded rod 13 to rotate. The rotation of the threaded rod 13 pulls the pull rope 11 fixedly connected to the lower end of the threaded rod 13 to move. At this time, the pull rope 11 pulls the two clamping rods 9 that are movably connected inside the channel 8 to move towards each other. The clamping rod 9 then moves completely into the channel 8.

[0031] By fitting the connecting holes 2 at both ends of the packing strap 1 onto the corresponding connecting rods 6, the packing strap 1 is wrapped around the box 3 to be packed. Then, the upper connecting plate 5 is placed on top. The connecting groove 7 reserved inside the upper connecting plate 5 matches the upper end of the connecting rod 6. Similarly, the above operation is reversed by twisting the threaded rod 13. The rotation causes the threaded rod 13 to reset and rotate, causing the pull rope 11 fixedly connected to the lower end of the threaded rod 13 to unwind. The spring 10 connected between the two clamping rods 9 resets and pushes the clamping rod 9 to move and match the clamping groove 15 reserved inside the connecting rod 6. At this time, the upper and lower connecting plates are installed, and the front and rear ends of the packing strap 1 are connected.

[0032] When the packing strap 1 needs to be disassembled, the same operation steps as above are followed to twist the threaded rod 13 to drive the locking rod 9 to move away from the slot 15 reserved inside the connecting rod 6.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
