Description
Technical Field
The invention relates to a lead seal, in particular to a safe lead seal.
Background
Lead seals are snap-lock like devices that are applied by a particular person after an item is boxed and the box door is properly closed. Once the lead seal is properly locked, it cannot be opened unless it is violently broken, and the broken lead seal cannot be reused. As long as the appearance of the box body is complete, the box door is correctly closed, and the lead seal printed with the corresponding lead seal is normally locked, the box body can be proved to have not been opened privately. For example, the electric meter used by each family in daily life is used for preventing some users who want to steal electricity from privately transforming the electric meter, two box doors of an electric box are tightly tied by a lead sealing wire, and then two ends of the lead sealing wire penetrate through a lead sealing block formed by lead through hot melting; for example, some articles that have been specially treated need to be sealed for storage and can only be removed for use, and therefore lead seals are required on the case to determine whether the articles are always in a desired storage state. At present, the common lead seal comprises a lead seal line and a lead seal block, and the lead seal block can be formed only by carrying out hot melting and molding on lead when in use, so that the process is troublesome; one includes a lock block and a cable tie, but is easily opened unintentionally and without damage; still other lead seals are made up of multiple parts and parts that when broken, can cause parts to spill into corners and cause unnecessary trouble.
Chinese patent CN201380014074.4 discloses a safety lead seal which is reliable and convenient to use, and the lead seal part or the whole lead seal can not fall off from the locking device of the lead seal due to failure, the safety lead seal has a lead seal foot and a lead seal head connected with the lead seal foot, the lead seal foot is provided with at least one clamping protrusion, the lead seal head is provided with at least one stopping splint, and each stopping splint is movably connected with the lead seal head through at least one hinge element. When this lead sealing is opened to needs, need outwards scratch the locking splint, then rotate to lead sealing and take off lead sealing, because lead sealing adopts plastics to make, therefore stress whitening phenomenon can appear at the in-process that turns up in the locking splint, if lead sealing is opened just can see easily, but direct manual pulling locking splint to turn up can lead to the fact the damage to the finger, or need adopt appurtenance just can destroy lead sealing, and open the process hard, it is difficult to open, meet the outside and receive unexpected destruction when dragging easily when unexpected, use unstablely.
Disclosure of Invention
The invention aims to provide a safe lead seal, which solves the defects that parts are easy to fall off or not easy to open after the lead seal is damaged and the use is unreliable in the prior art.
In order to solve the technical problems, the invention provides the following technical scheme:
a secure lead seal, comprising:
the end socket comprises an end socket body and a plurality of clamping arms, wherein the end socket body comprises an end socket cover and a pair of end sockets which are oppositely and fixedly arranged on the inner end surface of the end socket cover, clamping blocks are arranged on the end sockets, a pair of clamping arms which extend outwards are arranged on the outer peripheral surface of the end socket cover, and lock core holes which penetrate through the two ends of the end socket body are arranged on the end socket body;
the lock head is in one-way insertion fit with the lock cylinder hole;
one end of each pull wire is connected with the corresponding clamping arm, and the other end of each pull wire penetrates through the corresponding channel on the corresponding sealing pin to be connected with the lock head;
when the lead sealing device works, the lock head is pulled to enable the stay wire to move, so that the clamping arm is driven to bend towards one side of the sealing cover to deform, and the sealing head is rotated to take down the lead seal.
Furthermore, a sinking groove penetrating through two side faces of the clamping arm is formed in the outer top face of the clamping arm, one side of the sinking groove extends to the root of the clamping arm, and the other side of the sinking groove is connected with the sealing cover through a hanging pull arm.
Furthermore, the pull arm is provided with a necking part.
Furthermore, an arc-shaped groove penetrating through two side faces of the clamping arm is formed in the inner side face of the clamping arm, so that the clamping arm is easy to bend and deform.
Furthermore, the lock head comprises a lock head body, a plurality of elastic sheet teeth which are sequentially arranged along the axial direction of the lock head body are respectively arranged on two sides of the lock head body, a pull ring is arranged on the outer end face of the lock head body, the elastic sheet teeth are connected with corresponding convex teeth 7 on the side wall of the lock cylinder hole in a clamping manner, and the other end of the pull wire is connected to the inner end face of the lock head body.
Furthermore, a pair of umbrella hook bodies is arranged on the inner end face of the lock head body, the extending ends of the umbrella hook bodies are close to each other, and the other end of the stay wire is hung on the corresponding umbrella hook body.
Furthermore, the lock head further comprises a pair of elastic sealing plates fixedly arranged on the inner end face of the lock head body, the elastic sealing plates are V-shaped, the outer sides of the elastic sealing plates abut against the corresponding opening of the umbrella hook body, and a rhombic cavity is formed between the pair of elastic sealing plates.
Furthermore, the seal head is made of plastics, and the lock head is made of metal.
According to the technical scheme, the invention has the following beneficial effects:
because the seal head, the lock head and the pull wire are connected together, the phenomenon of scattering of parts can not occur after the lead seal is damaged, and the use is convenient;
the clamping arm can be deformed by pulling the lock head, so that the lead seal is easy to open;
because the lock head is in one-way inserting fit with the lock cylinder hole, the lock head is connected with the clamping arm through the pull wire, after the seal head is forcedly damaged, the lock head and the pull wire can be matched with other seal heads again to form a new lead seal, and the lock head and the pull wire can be repeatedly used for many times, so that the lead seal is easy to open and resources are saved;
the pull arm is broken when the clamping arm is bent, so that whether the lead seal is damaged or not can be easily indicated, and the safety is higher;
because the lead seal can be damaged only after the clamping arm is bent inwards and deformed, the lead seal is not easily interfered by external force and is reliable to use.
The invention is described in further detail below with reference to the figures and the detailed description.
