Common types of industrial handles are folding handles, U-shaped handles and chassis handles, etc., mainly used in industrial boxes, chassis cabinets, outdoor cabinets and other equipment, belonging to a high degree of participation in a low degree of attention to the segmentation of the accessory industry, but as an industrial accessory, the quality of the quality still need to follow strict standards.
Several indicators of industrial handles
Different from ordinary household handles, industrial handles have several indicators: 1, the basic requirement of industrial handles is to be thick, because industrial handles are generally used in heavy equipment above so industrial handles are very much thicker than ordinary household handles.
2, the corrosion resistance of industrial handles is outstanding, especially for chemical products above the use of industrial handles is very strict, such handles are some special industrial handles.
3, the shape of the industrial handles flexible use of a variety of products can be adapted to a variety of products, because the structure of the equipment is very complex, each one is different and diverse.
Hidden in the handle design of ergonomics industrial handles in the work scene of high-frequency applications make it the design of ergonomics have certain requirements. Let's talk about how to ergonomically design the handles to make users feel comfortable.
Speaking of ergonomics, first a simple explanation, it is through the study of people, machines, the laws of the relationship between the environment, and strive to make the overall performance of the human-machine-environmental system to achieve optimization.
Hand tools require the study of various types of hand postures. Human-machine system model: the system model centered on the “handle” is the main body of the person, the handle is the object, and the environment is the condition. The human being relates to the environment through the handle. Hand force analysis: “hand” interface design must comply with the following basic principles: (1) must effectively achieve the intended function; (2) and the operator's hand into the appropriate proportion, so that the operator to play the maximum efficiency; (3) must be in accordance with the operator's strength and operational capacity design, to give due consideration to gender, age, training and physical quality differences; (4) must be in accordance with the operator's strength and operational capacity design, to give due consideration to gender, age, training and physical quality differences; (5) must be in accordance with the operator's strength and operational capacity design, to give due consideration to gender, age, training and physical quality differences. (4) Handle requirements of the operation can not cause excessive fatigue and try to avoid static application of force. When designing handles, grips, hand-contact screens and other product safety holes for tools and devices, consider the size of the hand and its movement possibilities. The average values of the main dimensions of the hand are shown in the figure and given in the table below, where the upper dimensions are for the male hand and the lower for the female hand. The maximum length of the male hand is 21 cm and that of the female 20.5 cm. The hand can swing 135° when the fist is clenched and 150° when the fingers are extended.
The size of the handle: (1) the cross-sectional size of the grip part of the handle depends on its shape, material properties. For hand grips, the size of the tiger's mouth of the hand is used as a reference; for hand grips, the thickness and width of the fingers are used as a reference. For optimum ergonomic grip, engineers should allocate sufficient handle width to accommodate the standard “four fingers”.
(2) The length of the handle, which depends on the width of the palm. 5% of women and 95% of men have a palm width in the range of 71mm to 97mm, so a more suitable handle length is 100mm to 125mm.
(3) Implementation of standardization of ergonomic parameters. This can make the design standardization, simplify the design work, shorten the design cycle, simplify the production process, improve the quality of the system, reliability, reduce production costs. Give the human body parameter change rule, provide a complete reference series, for the design and research work to create conditions.
