A luminescent body, a battery tray provided with a battery pack and a spring are arranged in a barrel body, one pin of the luminescent body is contacted with the battery pack, the other pin is arranged at the bottom of the battery tray and is contacted with the spring, the tail end of the luminescent body is assembled with a back cover provided with a fixing sheet and accommodating a press switch and a press key, the tail end of the back cover is connected with a key hanging ring, and then the utility model is formed. When the utility model is used, the press key is pressed, the press switch is driven to make batteries communicate with the luminescent body which emits light, when pressure is relieved, the press switch is reset by the restoring force of the spring, the luminescent body is extinguished. The tail end of the press switch is prolonged and extended into a concave hole of the tail end of the back cover so as to increase the use firmness.

Description

The improvement of key-ring ray structure

The utility model relates to a kind of daily living article, particularly relates to the improvement of key-ring ray structure.

Known key-ring ray structure, as shown in Figure 1, its control knot is arranged at tail end, during use more not smoothly, among Fig. 1,100 is cylindrical shell, and 200 is luminous element, and 300 is battery tray, and 400 is battery pack, 500 is spring, and 600 is bonnet, and 700 is push switch, and 800 is key-ring.Fig. 2 has provided another kind of structure.Among Fig. 2,100 ' is cylindrical shell, and 200 ' is luminous element, and 300 ' is battery tray, and 400 ' is battery pack, and 500 ' is spring, and 600 ' is bonnet, and 700 ' is push switch, and 800 ' is key hanging ring, and 900 is button, and 6001 is stator, and 6002 is key hole.This structure has changed control structure is located at side, but when implementing to use, partly structure is firm inadequately for push switch, loosening easily, whole use smooth and easy of influence.For improving the problems referred to above, the inventor continues to grind the road of improvement deeply, and proposes this utility model so that it more attains perfect.

The purpose of this utility model is to provide a kind of improvement of key-ring ray structure, and it makes the structure of push switch and button stable more with rationally, has increased the stability of whole use.

The improvement of the key-ring ray structure that this use is novel, this key-ring comprises cylindrical shell, be contained in the cylindrical shell and be provided with the luminous element of two pins, be contained in battery pack, spring, bonnet in the battery tray, be contained in the push switch in the bonnet, be contained in the interior button of keyhole of bonnet side, impinge upon the stator and the key hanging ring of bonnet one end, be characterized in that the push switch end is provided with extension, bonnet tail end inner edge is provided with shrinkage pool, and the extension rear end is embedded in the shrinkage pool.

Key-ring ray structure of the present utility model improvement, its advantage are that to have the combination that makes push switch really more firm, the more apparent tight effect of overall structure.And this effect can be improved former control structure switch really and is located at the bottom, grips when using, pushes more smoothly, and construction of switch is disliked firm inadequately drawback slightly.The utlity model has following accompanying drawing:

Fig. 1 is the three-dimensional exploded view of known key-ring ray structure.

Fig. 2 is the three-dimensional exploded view of another known key-ring ray structure.

Fig. 3 is the three-dimensional exploded view of the utility model one preferred embodiment.

Fig. 4 is the combined planar cut-away view of the utility model one preferred embodiment.

Fig. 4 A is that the behaviour in service plane of the utility model one preferred embodiment is cutd open and shown

Figure.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1, Fig. 2 are the three-dimensional exploded view of known key-ring ray structure, and its operating position and shortcoming are no longer narrated in this as described above.

Fig. 3 is the three-dimensional exploded view of a preferred embodiment of the present utility model, can find out by this figure, key-ring ray structure improvement of the present utility model, formed by a cylindrical shell 1, a luminous element 2, a battery tray 3, a battery pack 4, a spring 5, one bonnets 6, a push switch 7, a key hanging ring 8 and a button 9 etc.Wherein battery tray 3 is divided into upper and lower two parts, be respectively equipped with steady pin 33 and fixing hole 34, the side offers a groove 31: an end of bonnet 6 is installed a stator 61, and be provided with a key hole 62 in the appropriate location of side, the tail end inner edge is provided with a shrinkage pool 63: push switch 7 ends are provided with extension 71, and the rear end diameter of extension 71 is slightly less than the aperture of shrinkage pool 63; During combination battery pack 4 packed in the battery accommodation seat 35, fasten battery tray 3, make steady pin 33 insert fixing holes 34 and fixed, luminous element 2 bottoms are inserted in the luminous element seat 32, pin 21 and battery pack 4 one end in contact, another pin 22 prolong groove 31 and extend, and are fixed in battery tray 3 bottoms.Luminous element 2 and battery tray 3 cylindrical shell 1 of packing into, and make luminous element 2 one ends protrude from peristome 11 places.Push switch 7 is installed in the Hou lid 6, the one end protrude from stator 61 central authorities through hole and is connected with spring 5, the middle conical surface that partly is joins with the conical surface of button 9 bottoms, and makes the intercalation of extension 71 Hous end go into Hou to cover in 6 the shrinkage pool 63.The other end of button 9 protrudes from key hole 62 places.Make up bonnet 6, and be connected with a key hanging ring 8 in bonnet 6 ends.

Fig. 4 is the combined planar cut-away view of the utility model one preferred embodiment.Can learn with reference to Fig. 4 A, push button 9, push switch 7 promptly is subjected to the transmission of the conical surface to the battery-end displacement, and an end contacts with battery pack 4, makes luminous element 2 electrified light emittings through spring 5, pin 22.Loosen button 9, the restoring force of mat spring 5 resets push switch 7, button 9, luminous element 2 outages are extinguished, effectively reach the function of open and close luminous element 2, and in use, push switch 7 two ends all are subjected to fixed head 61, the constraint of shrinkage pool 63, support, guarantee switch 7 vertically rectilinear motion make overall structure more shape be firm.

The above only is the utility model one preferred embodiment, if comply with change or modification that conception of the present utility model is done, all should be within protection range of the present utility model, and the spy gives Chen Ming earlier.
