What is a tension spring?
Tension springs are a variety of practical springs that are widely used in various industries today. This type of spring offers various capabilities. Tension springs are actually a type of spring that is designed as a chain of rings attached to each other and very close to each other with two hooks at both ends.
Their function is such that when the spring is pulled, mechanical energy is stored in it and when it is released, this energy is released, thus achieving its function in storing and transferring energy. Tension springs have high durability and resistance, hence they are used for various industrial, sports, etc. purposes. In addition, these springs have a very long life, so they can be considered as a functional part in various equipment. In this type of springs, by applying tensile force, they are stretched and opened, and then they lean towards each other again when the force is cut off. When they are used in parts, due to their efficiency, they prevent the separation of two parts from each other and make them lean towards each other.

The function of the tension spring
Tension springs, like other springs, work according to Hooke's law, they expand when force is applied and return to their normal state when force is removed. In fact, by applying force and stretching it, it stores mechanical energy in them, and finally, by removing this force, it causes the release of this mechanical energy in them. The tension springs are connected to the parts by means of the hooks in their two heads, and when they want to move away from each other, they approach each other with the action of the tension springs.
Due to the materials used in the construction of the tension springs, they have such a capability, that is, the alloys used in their construction have caused such a behavior in these springs, as a feature of the reversibility of the state. they have the original state and if force is applied to them, they will not undergo permanent deformation and will return to their original state.
Types of tension spring
There are different types of tension springs that have different uses depending on the type and materials used in their construction.
hook spring
A hook spring is a spring that has a hook on one side, by which it can be connected to a surface or system. Due to their design, hook springs are used to hang objects, etc. on the ceiling or other surfaces.
Pronged spring
These springs are designed in spiral form, which have two prongs parallel to their body, and for this reason, they are different from other springs. These springs have various applications in the industry and due to their high flexibility, they are well used for cases that require high flexibility.

quinque spring
This spring is designed in the form of a ring, and due to its special shape, it is used for situations that require easy installation and removal. Quink springs are designed in the form of rings, which have high flexibility and therefore can be very suitable for repeated operations.
Applications of tension spring
Tension springs can be used in the following cases, including:
Automotive industry: The use of tension springs in car wipers can be one of the most important uses of tension springs. In addition, the tension spring can be used in the suspension system, clutch, etc.
Toys: These springs can be used in different toys and provide different performance depending on the type and location. For example, these tension springs can be used to move or throw some toys.
Electronics industry: In many electronic components, tension springs play an auxiliary role in creating movement and adjusting pressure.
The use of tension springs in the construction of doors and windows: these tension springs can be used for better opening and closing of doors and windows.
Agricultural equipment: Other applications of tension springs include their use in agricultural equipment and machinery.
Medical industry: In the medical industry and related instruments, you can see the wide applications of tension springs, such as optometry devices, operating room lights, etc.
