Abstract

The utility model discloses a safe bead necklace rope, which comprises a plurality of beads and a connecting rope for connecting the beads. The connecting rope is a twisted stay cord. By adopting the twisted stay cord, the bead necklace rope will naturally twist into one when the extending end of the bead necklace rope is free. The length of the untwisted bead necklace rope section is not more than 3 cm and no object will be taken in, so the harm to the baby caused by the free end of the bead necklace rope can be avoided. The structure is simple and the safety is higher.

Description

A kind of safe bead cord

Technical field

The utility model relates to the curtain technical field, relates in particular to a kind of theft-resistant link chain pearl rope of curtain folding and unfolding.

Background technology

Manual curtain coiling apparatus, majority are to rely on pelletron, and with pulling moving bead cord, the drive curtain is done and rolled or put down; This kind bead cord stretch out a sagging bead cord, in family uses, can occur twining baby's incident, cause and cause injury, disable, even deadly incident; Increase a pulley in the free end bottom, this pulley is fixed on the body of wall for this reason, but also because of the user does not pack into pulley to bead cord, causes above-mentioned incident to still have the possibility of generation, and institute is still dangerous in this way; For this reason through constantly very improvement of research, the patent No. is that 200420071930.8 Chinese patent discloses a kind of safe pelletron that is used to drive the curtain body folding and unfolding, this pelletron is made up of several beads and the line that is connected between bead, the two ends of pelletron is incorporated on a connecting seat, form a chain link, form the holding tank that is complementary with bead in the Connection Block, and be extended with splitting groove by holding tank towards the Connection Block end, the width of splitting groove is less than the holding tank internal diameter; Bead on the described pelletron termination is embedded in the holding tank.Adopt such structure, chain link is subjected to certain external force and does the time spent, but it is embedded at the termination bead trip-free in the Connection Block, promptly utilize the connectivity structure design of holding tank and splitting groove and splitting groove to rise automatically to receive principle and realize, thereby the oneself who reaches chain link unties, avoid its cover to be buckled in the people and to cause unnecessary accident, but this structure still can not well solve contingency, and fault is also more.

The utility model content

Technical problem to be solved in the utility model provides a kind of safe bead cord, avoids its cover to be buckled in the people and to cause some unnecessary accidents, and simple in structure, security performance is better.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of safe bead cord, bead cord is made up of several beads and the line that is connected between bead, it is characterized in that: described line adopts the stay cord that the twist is arranged.

As preferably, the described stay cord that the twist arranged is provided with 6~8 and twists with the fingers for per 10 millimeters.

Further improve, described have the stay cord of the twist under natural winding state bead cord to be divided into two sections, and the hypomere bead cord is not twined between the bead cord of epimere for twining section, and the per share bead cord length of epimere is not more than 3cm, to avoid entangling any object.

As improvement, the bead cord of described winding section is synthesized one with two strands.

Compared with prior art, advantage of the present utility model is: adopt the bead cord that the twist is arranged, when the bead cord external part is free state, can be wound in one by nature between per share bead cord, its length of pelletron ran of not twining is not more than 3cm, therefore can not be inserted in any object, thereby avoid free end because of bead cord to cause injury the baby; Simple in structure, security performance is better.

Description of drawings

Fig. 1 is bead cord of the present utility model and window shade arrangement schematic diagram;

Fig. 2 twines schematic diagram for the utility model bead cord.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1~2: a kind of safe bead cord, bead cord is made up of several beads that are intervally arranged 2 and the line that is connected between bead;

Traditional bead cord is wrapped on driving wheel and the follower, and the stay cord 1 that the line in this bead cord adopts is a twist-free rope, and the external part of this stay cord 1 can freely hang down, so that pulling; What key point of the present utility model was the line employing is the stay cord 1 that the twist is arranged, there is the stay cord 1 of the twist to be provided with 6~8 and to twist with the fingers for per 10 millimeters, because the effect of the twist, when the bead cord external part is free state, can wind up by nature between one bead cord and another burst bead cord, thereby two bursts of bead cord are wound in one, make bead cord under natural winding state, bead cord is divided into two sections, the hypomere bead cord is for twining section, do not twine between the bead cord of epimere, the per share length of bead cord that does not have to twine is not more than 3cm, thereby can't spur, have only when the free end 4 of this bead cord is inserted in the follower 3 of lower end, just separated between the described bead cord, therefore can guarantee fully when the user does not pack bead cord into follower 3 or bead cord when follower 3 is deviate from, guarantee can not be inserted in any object, thereby avoid lasso because of the free end 4 of bead cord to cause injury the baby.
