Background technology

Tongue tube is a kind of special key of magnetosensitive, is " magnetron " again, and its two contacts are made by special material, is encapsulated in the glass tube of vacuum, as long as use magnet near it, two nodes of tongue tube will be pulled together, and make circuit turn-on.The tongue tube life-span is generally at hundreds thousand of times to millions of times.

If the exploitation or in product, to use certain tongue tube, just must assess it, whether meet design requirement, the life-span of article can define by service time or action frequency, the life-span is one of its important parameter.Life-span is the average service time of a certain series products, and durability test is the method for research life of product feature, and this method can be carried out in the various service conditions of laboratory simulation.Durability test is one of the most basic most important project in the fail-test, and it is product to be placed on investigate its inefficacy (damage) change with time under the specific test condition.By durability test, can understand life characteristics, inefficacy rule, crash rate, the mean lifetime of product and the various failure modes that in the durability test process, may occur.As in conjunction with failure analysis, can further understand fully the main failure mechanism that causes product failure, as the foundation of reliability design, reliability prediction, improvement new product quality and definite reasonably screening, customary (assurance in batches) test condition etc.If can under the condition that does not change failure mechanism, test accelerated life test that Here it is with the method that strengthens stress in order to shorten test period.Can estimate the reliability of products level by durability test, and improve new product reliability level by Quality Feedback.

In sum, the utmost point need design a kind of device that can test the tongue tube life-span, in order to understanding reliability of products level, and the reliability level of raising new product.

The utility model content

The purpose of this utility model is to provide a kind of tongue tube endurance testing device, and is simple in structure, with low cost, can test out the mean lifetime of a collection of tongue tube easily and fast.

The technical scheme that realizes the utility model purpose is: a kind of tongue tube endurance testing device, comprise casing, base, motor, rotating disk, magnet, counter and switch, described casing is fixed on the base top, the upper surface of casing is provided with groove, be provided with a plurality of chassis holes that are used to place tongue tube near groove, the upper surface of casing also is provided with all tongue tube socket and the pilot lamp corresponding with chassis hole; Described motor is fixed between casing and the base, and the motor shaft of motor passes the bottom of the groove of casing; Described rotating disk is fixed on the motor shaft of motor, and is positioned at the groove of casing; Described magnet is provided with a plurality of, and is fixed on the edge of rotating disk; Described counter and switch are fixed on the casing, and counter is used for the number of times of register lamp flicker, and switch is used to control whole device work.

The groove of described casing is circular, and is positioned at the center of casing upper surface, and the motor shaft of motor passes from the center of the bottom of groove.

A plurality of chassis holes on the described casing evenly are arranged on the place near groove, and motor shaft, chassis hole, tongue tube socket and pilot lamp are located along the same line.

Described rotating disk also is circular, and a plurality of magnet evenly are fixed on the edge of rotating disk.

Described counter and switch are separately fixed on two angles of upper surface of casing.

The utlity model has following beneficial effect: (1) the utility model makes the life-span that is used for testing tongue tube by the simulation tongue tube is actual, when magnet when the tongue tube, the tongue tube folding once, the pilot lamp flicker corresponding with tongue tube once, do not glimmer as pilot lamp, then Dui Ying tongue tube damages, and this method of testing accuracy rate is very high, and proving installation is simple in structure, and is cheap for manufacturing cost.

Description of drawings

For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Label is in the accompanying drawing:

Casing 1, groove 11, chassis hole 12, tongue tube socket 13, pilot lamp 14, base 2, motor 3, motor shaft 31, rotating disk 4, magnet 5, counter 6, switch 7, tongue tube 8.

Embodiment

(embodiment 1)

See Fig. 1 and Fig. 2, present embodiment comprises casing 1, base 2, motor 3, rotating disk 4, magnet 5, counter 6, switch 7 and tongue tube 8.

Casing 1 is fixed on base 2 tops, the center of the upper surface of casing 1 is provided with circular groove 11, evenly be provided with 20 chassis holes 12 that are used to place tongue tube 8 near groove 11 places, the upper surface of casing 1 also is provided with all tongue tube socket 13 and the pilot lamp 14 corresponding with chassis hole 12.Motor 3 is fixed between casing 1 and the base 2, and the motor shaft 31 of motor 3 passes from the center of the bottom of the groove 11 of casing 1.Motor shaft 31, chassis hole 12, tongue tube socket 13 and pilot lamp 14 are located along the same line.Circular rotating disk 4 is fixed on the motor shaft 31 of motor 3, and is positioned at the groove 11 of casing 1; Magnet 5 is provided with 12, and evenly is fixed on the edge of rotating disk 4.Counter 6 and switch 7 are separately fixed on two angles of upper surface of casing 1, and counter 6 is used for the number of times of register lamp 14 flickers, and switch 7 is used to control whole device work.
