Abstract
The utility model discloses an air leakage testing device which comprises a workbench. An accommodation cavity in which a horn is placed is arranged on the workbench. A sealing gland which is matched with a cavity opening is arranged on the accommodation cavity. An air through hole which is communicated with the inside of the accommodation cavity is arranged on the sealing gland. The air leakage testing device further comprises a testing air tube. The testing air tube is communicated with the air through hole. A clamping device which presses the sealing gland on the accommodation cavity is arranged on the workbench. According to the utility model, the air leakage testing device has the advantages of simple structure and convenient use; the horn is placed in the accommodation cavity; the sealing gland is tightened and is clamped by the clamping device; a ventilation switch is turned on to test whether the horn leaks air; the operation is simple and accurate; the cost is reduced; and the efficiency is improved.
Description
Technical field
The utility model relates to a kind of gas leakage proving installation.
Background technology
Thereby electric automobile horn is to sound by the vibration of metallic membrane.Electric automobile horn is made up of iron core, magnetic coil, contact, armature, diaphragm etc.When the driver presses horn switch, electric current passes through coil through the contact, coil produces magnetic force and inhales lower armature, forces diaphragm to move, and armature moves the contact is disconnected, current interruptions, coil magnetic force disappears, and diaphragm sets back together with armature under self elasticity and spring leaf effect, and contact closure circuit is connected again, electric current produces magnetic force by the contact flowing through coil, repeats above-mentioned action.The diaphragm that circulates so repeatedly constantly vibrates, thereby sends sound equipment.Soundboard and diaphragm rigid attachment, can make the vibration smooth-going sound more melodious.
Therefore the sealing of loudspeaker casing is directly connected to tonequality and the product quality of Horn loudspeaker box, can be to the detection of leaking gas of loudspeaker casing before dispatching from the factory.The present pick-up unit complex operation that uses, test result is not very accurately and reliably, can't guarantee the product quality of dispatching from the factory, the cost of labor height, efficient is low.
The utility model content
The utility model purpose: in order to overcome the deficiencies in the prior art, the technical solution adopted in the utility model is:
The gas leakage proving installation comprises worktable, it is characterized in that: described worktable is provided with for the ccontaining cavity of placing loudspeaker, and described ccontaining cavity is provided with the sealing gland that matches with cavity hatch; Described sealing gland is provided with the gas via-hole that is connected with ccontaining inside cavity.
Also comprise the test tracheae, described test tracheae is connected with gas via-hole.
Described test tracheae is connected by sealing gasket and nut are airtight with gas via-hole.
Described worktable is provided with for the clamp device that sealing gland is pressed on the ccontaining cavity.
Described worktable is provided with the ventilation switch.
Described sealing gland is provided with is convenient to the handle that draws back or compress.
Beneficial effect: the gas leakage proving installation that the utility model provides, simple in structure, easy to use, loudspeaker are positioned in the ccontaining cavity, cover tightly sealing gland, further clamp with clamp device again, open the ventilation switch and carry out test horn and whether leak gas, operate simple and easy, accurately and reliably, reduce cost, improved efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Be illustrated in figure 1 as a kind of gas leakage proving installation, comprise worktable 1, described worktable 1 is provided with for the ccontaining cavity 2 of placing loudspeaker, and described ccontaining cavity 2 is provided with the sealing gland 3 that matches with cavity hatch; Described sealing gland 3 is provided with the gas via-hole 4 that is connected with ccontaining inside cavity.Also comprise test tracheae 5, described test tracheae 5 is connected with gas via-hole 4.Described test tracheae 5 is connected by sealing gasket and nut are airtight with gas via-hole 4.Described worktable 1 is provided with for the clamp device 6 that sealing gland is pressed on the ccontaining cavity.Described worktable 1 is provided with ventilation switch (not shown).Described sealing gland 3 is provided with is convenient to the handle 7 that draws back or compress.
The gas leakage proving installation that the utility model provides, simple in structure, easy to use, loudspeaker are positioned in the ccontaining cavity 2, cover tightly sealing gland 3, further clamp with clamp device 6 again, open the ventilation switch and test, it is simple and easy accurate to operate, and reduces cost, and has improved efficient.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (6)
