Description

Technical Field

[0001] The utility model belongs to the technical field of cable ties, and in particular relates to a double-locking tie with a QR code label. Background Art

[0002] Cable ties, also known as cable ties, cable ties, and lock ties, are straps used to tie things together. They can generally be divided into nylon cable ties, stainless steel cable ties, plastic-sprayed stainless steel cable ties, etc. according to their materials. They can be divided into ordinary cable ties, retractable cable ties, label cable ties, fixed lock cable ties, latch cable ties, heavy-tension cable ties, etc. according to their functions. In order to supervise the quality of concrete projects, general supervisory departments will witness the sampling, and these concrete specimens and powder specimens are generally tied tightly with cable ties during transportation. When the quantity is large or large, plastic bags are generally used to seal the samples. At this time, cable ties are needed to tighten the plastic bags to ensure the particularity of the concrete specimens or powders and avoid replacement. However, some existing cable ties often have certain deficiencies when used, so they need to be improved.

[0003] In the Chinese patent with publication number CN211686434U, a binding strap is mentioned, including a strap body and a locking component, wherein the locking component is arranged at one end of the strap body, the locking component includes a locking body, and the locking body is provided with a channel for the other end of the strap body to slide out; the locking component also includes a locking piece and an unlocking piece, the locking piece is arranged in the channel, and the locking piece is configured to be able to selectively abut against the groove on the strap body; one end of the unlocking piece is connected to the locking piece, and the other end extends out of the locking body, and the unlocking piece is configured to enable the locking piece to deform and disengage from the groove. The locking piece of the binding strap can selectively abut against the groove on the strap body, thereby locking the strap body, and the locking piece can be deformed and disengaged from the groove through the unlocking piece. When disassembling, there is no need to damage the binding strap, and it can be reused, saving resources.

[0004] However, although the above technical solution can achieve the purpose of locking an object when used, if it is used to lock a plastic bag, the arc-shaped position of the belt body will contact the sealing surface of the plastic bag. The arc-shaped position of the belt body is relatively smooth. If the object inside the plastic bag is subjected to severe shaking during transportation, the larger concrete specimen inside the plastic bag will collide with the belt body at the sealing portion of the plastic bag, which may easily cause the concrete specimen to fall off or even damage the concrete specimen. Therefore, it has certain limitations when used. Utility Model Content

[0005] The purpose of the utility model is to provide a double-locking tie strap with a QR code label to solve the problem in the background art that the friction between the curved arc of the tie strap and the object to be tied is small, which easily causes the tie strap to slip.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A double-locking tie strap with a QR code label comprises: a tie strap body, a hand-tear tape provided inside the tie strap body, a positioning block fixedly connected to one side of the top of the tie strap body, a connecting strap fixedly connected to the inside of the hand-tear tape, three groups of fixed cones fixedly connected to one side of the inner side wall of the connecting strap, a plurality of clamping blocks fixedly connected to the other side of the inner side wall of the connecting strap, two clamping rods passing through the interior of the positioning block, and an extrusion block fixedly connected to the surface of the clamping rod.

[0008] Preferably, connecting rings are fixedly connected to both sides of the positioning block, and a ring cover is threadedly connected to the surface of the connecting ring. A first lock hole is opened on one side of the top of the positioning block, and the surface of the connecting belt passes through the inside of the first lock hole. A second lock hole is opened on the other side of the top of the positioning block.

[0009] Preferably, two sliding grooves are provided inside the positioning block, and the extrusion block slides inside the sliding grooves, and a blocking block is fixedly connected to the inner side wall of the sliding groove.

[0010] Preferably, a compression spring is fixedly connected to one side of the blocking block, and an end of the compression spring away from the blocking block is fixedly connected to one side of the extrusion block.

[0011] Preferably, two through holes are provided on one side of the bottom of the binding belt body, and the surface of the connecting belt passes through the inside of the through holes, and a QR code label is fixedly connected to the other side of the top of the binding belt body.

[0012] Preferably, a stabilizing block is fixedly connected to the inner side wall of the first lock hole, and the clamping rod passes through the interior of the stabilizing block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) After a larger concrete specimen is placed inside a plastic bag, the plastic bag can be tightened by the binding belt body. At the same time, after the binding belt body tightens the plastic bag, it can prevent the bending part from slipping at the pinched part of the plastic bag. The binding belt body is designed with double lock holes, which makes it more stable when locking the plastic bag. Smaller sample specimens can also be tied up to prevent them from being replaced. At the same time, the locking belt and the binding belt body are easy to separate to avoid direct damage and facilitate subsequent reuse.

[0015] (2) When the clamping block is stuck in the upper position of the inclined part of the clamping rod, the inclined part of the clamping rod is located between the two adjacent clamping blocks, and the clamping rod is reset. The annular cover prevents the clamping rod from moving to the left, causing the clamping rod to fall off from between the two adjacent clamping blocks. At the same time, the inspection personnel can scan the QR code label to understand whether the concrete specimen inside the plastic bag has been replaced and identify the authenticity of the concrete specimen.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figures 1 to 4As shown, a double-locking tie strap with a QR code label includes a tie strap body 1, a hand-tear strap 2 is arranged inside the tie strap body 1, a positioning block 3 is fixedly connected to one side of the top of the tie strap body 1, a connecting strap 4 is fixedly connected to the inside of the hand-tear strap 2, three groups of fixing cones 5 are fixedly connected to one side of the inner side wall of the connecting strap 4, and a plurality of clamping blocks 6 are fixedly connected to the other side of the inner side wall of the connecting strap 4, two clamping rods 8 are passed through the interior of the positioning block 3, and an extrusion block 9 is fixedly connected to the surface of the clamping rod 8. By setting the hand-tear tape 2, the hand-tear tape 2 and the connecting tape 4 can be finally separated from the binding tape body 1. One side of the hand-tear tape 2 is connected to the binding tape body 1 through an intermittent connecting block, which is convenient for subsequent tearing. This technology is a prior art and will not be described in detail. By setting the fixed cone 5, when the connecting tape 4 ties the plastic bag, the ring-shaped position can be stably connected to the plastic bag to avoid sliding. The end of the clamping rod 8 close to the extrusion block 9 is designed to be inclined to facilitate the passage of the clamping block 6. Through the setting of the clamping block 6, it can be engaged with the clamping rod 8. Through the setting of the extrusion block 9, the compression spring 11 can be squeezed.

[0024] Two sliding grooves 10 are provided inside the positioning block 3, and the extrusion block 9 slides inside the sliding grooves 10, and the inner sidewall of the sliding grooves 10 is fixedly connected with a blocking block 17. By opening the sliding grooves 10, the extrusion block 9 is able to slide inside it.

[0025] A compression spring 11 is fixedly connected to one side of the blocking block 17, and the end of the compression spring 11 away from the blocking block 17 is fixedly connected to one side of the extrusion block 9. The setting of the blocking block 17 allows one end of the compression spring 11 to be squeezed by the extrusion block 9 while the other end is blocked, causing it to be compressed, thereby allowing the clamping rod 8 to move to the left. The surface of the clamping rod 8 passes through the interior of the blocking block 17, allowing it to move.

[0026] The inner side wall of the first lock hole 12 is fixedly connected with a stabilizing block 7, and the clamping rod 8 runs through the inside of the stabilizing block 7. Through the arrangement of the stabilizing block 7, the clamping rod 8 plays a certain guiding role when moving, and makes it more stable.

[0027] Example 2:

[0028] See also Figures 1 to 3As shown, both sides of the positioning block 3 are fixedly connected with a connecting ring 14, and the surface of the connecting ring 14 is threadedly connected with an annular cover 15. A first locking hole 12 is opened on one side of the top of the positioning block 3, and the surface of the connecting belt 4 passes through the interior of the first locking hole 12. A second locking hole 13 is opened on the other side of the top of the positioning block 3. The provision of the connecting ring 14 allows the annular cover 15 to be connected thereto, while blocking the end of the clamping rod 8 close to the connecting ring 14 to prevent it from being pulled at will. The opening of the first locking hole 12 and the second locking hole 13 allows the connecting belt 4 to pass through the interior thereof, so that the connecting belt 4 can be fixed therein. It should be noted that the internal structures of the first locking hole 12 and the second locking hole 13 are the same, but the directions are opposite, so that the connecting belt 4 can be fixed after passing through the interior thereof.

[0029] Two through-holes 18 are provided on one side of the bottom of the tie strap body 1, and the surface of the connecting strap 4 extends through the interior of the through-holes 18. A QR code label 16 is fixedly attached to the other side of the top of the tie strap body 1. The through-holes 18 allow the connecting strap 4 to pass through the interior of the tie strap body 1. It should be noted that the apertures of the through-holes 18 are larger than the apertures of the first lock hole 12 and the second lock hole 13, which facilitates the passage of the connecting strap 4.

[0030] The working principle of the present invention is as follows: the staff puts the concrete specimen or powder into the inside of the plastic bag in advance, then pinches the plastic bag, and then fits the binding belt body 1 with the pinched part of the plastic bag, and then passes the end of the connecting belt 4 through the through hole 18 and the inside of the first lock hole 12. At this time, several clamping blocks 6 on the other side of the inner wall of the connecting belt 4 enter the inside of the through hole 18 and the first lock hole 12, and then the staff pulls it upward, and then the clamping block 6 squeezes the inclined part of the clamping rod 8, and the clamping block 6 squeezes the inclined part of the end of the clamping rod 8 When squeezing, the clamping rod 8 moves to the left, and at the same time, the squeezing block 9 on the clamping rod 8 squeezes the compression spring 11 to compress it. When the clamping block 6 passes through the inclined part of the clamping rod 8 and is located above it, the compression spring 11 is reset, so that the clamping block 6 contacts the position above the inclined part of the clamping rod 8, so that the clamping rod 8 is fixed. At the same time, several fixing cones 5 at the bending part of the connecting belt 4 are inserted into the inside of the plastic bag to keep it fixed and avoid sliding. For safety reasons, the staff can also insert the connecting belt 4 after passing through the first lock hole 12 and then The second locking hole 13 is passed through the inside of the second locking hole 13 to obtain a double engagement, making the plastic bag more stable when tied. When the binding strap body 1 needs to be disassembled later, the staff rotates the annular cover 15 to separate the annular cover 15 from the connecting ring 14. Then the staff pulls the clamping rod 8 to the left, thereby causing the extrusion block 9 to squeeze the compression spring 11. At this time, the clamping rod 8 moves in the direction of the connecting ring 14, thereby separating the clamping block 6 located above the inclined part of the clamping rod 8 from it. The staff continuously pulls the connecting strap 4 downward to separate the connecting strap 4 from the first locking hole 12, thereby separating the tied plastic bag from the binding strap body 1. If the binding strap body 1 is damaged and difficult to use later, the staff can directly separate the connecting strap 4 from the binding strap body 1 by tearing the strap 2 by hand, which is convenient for the staff to take the concrete specimen or powdered object inside the plastic bag. The staff can scan the QR code label 16 on the binding strap body to observe whether the photo of the plastic bag is consistent with the appearance of the plastic bag and the binding strap body 1 seen on site, so as to determine whether the concrete specimen inside the plastic bag has been replaced.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
