    The lead screw cover is a kind of protective cover, also known as the lead screw cover, which can effectively protect the lead screw, light bar, shaft, column and other parts from external pollution and damage such as dust. Stretching or compressing motion, can be used vertically or horizontally. It is recommended to use a plastic or aluminum support ring when used horizontally, to maintain a certain uniform distance between the inner cavity of the shield and the screw rod to extend the service life. When the stretch length is large, a metal ring can be added to each fold to improve the stability of the shield. The connection or fixed end usually uses a metal flange, or a ferrule can be selected.
    Order requirements:
    Ordering example: shield inner diameter × outer diameter × stretched length × compressed thickness × material design parameters: length after stretching, length after shrinking, length at lower connection length, length at upper connection, outer ring diameter, inner ring diameter connection, outer diameter connection, inner diameter, note As long as the user fills in the above data and selected materials when ordering, our company will design and manufacture them.

    2. If the user has special requirements on the type of shield, our factory can negotiate with the user to design and meet the requirements.
    Technical Description:
    In general, the ratio of the length of the sheath after stretching to the thickness after shrinking is one meter to fifteen centimeters. It can also be processed to produce telescopic sheath products with larger or smaller ratios according to customer requirements. A basic component of it is that a PVC skeleton supporting and stabilizing is installed in each hinge. This skeleton can be closely connected with the external hinge material through different processing methods. One is thermal bonding. At a certain temperature, with the help of special flux, the inner PVC skeleton can be firmly bonded with the outer hinge. This method can be used if the shield is used in a medium temperature environment. This kind of thermal bonding shield does not need to be maintained at all, and is waterproof, dustproof, oil-resistant and acid-resistant.
    The other is a sewing method, which is used in high-temperature working environments. Sewing with a special thread is durable and durable even under extreme loads. The PVC skeleton is sewn on each fold to reinforce the stable cover.

    The lead screw cover is a kind of protective cover, also known as the lead screw cover, which can effectively protect the lead screw, light bar, shaft, column and other parts from external pollution and damage such as dust. Stretching or compressing motion, can be used vertically or horizontally. It is recommended to use a plastic or aluminum support ring when used horizontally, to maintain a certain uniform distance between the inner cavity of the shield and the screw rod to extend the service life. When the stretch length is large, a metal ring can be added to each fold to improve the stability of the shield. The connection or fixed end usually uses a metal flange, or a ferrule can be selected.


    The screw cap can be divided into two forms according to the processing method, and also considering the factors that different materials are suitable for different processing technologies.


    One is a screw guard supported by a steel ring. This shield uses a variety of fabrics and is supported by a hard wire ring. It can work normally at a high temperature of 110 ° C and a low temperature of -40 ° C. It can effectively prevent dust, water, oil, anti-emulsions and chemicals. This shield has the characteristics of neat appearance and is not easy to deform. Based on its tightness and strength, this shield can be used for ventilation and dust removal of many machinery. The flexibility of this product is not only in the choice of materials, but also in that it can determine the required diameter and length according to the specific requirements.


    The other is the sewing screw cover. The circular screw cover is made of stamped discs. The two inner edges and the two outer edges are sewn together. It can be better by sewing. The shape is stable and firm in the horizontal direction. There are many choices of materials according to the working environment.
