Abstract

The utility model relates to a hand-hold flash rotation lamp which is a toy lamp and is composed of a lamp cover, a lamp table and a handle, wherein, toothed racks can be alternatively pressed and reset through the action of a pressing spring by holding the handle and pressing the toothed racks in the lamp table with a thumb, so a transmission mechanism in the lamp table is driven to make a shaft extending from the upper part of the lamp table continuously rotate towards one direction and drive a transparent lamp cover sheathed on the shaft to rotate. A battery is arranged in the handle, a conductive wire is connected to a group of copper sheets at the upper end of the lamp table, and a bulb in the lamp cover is connected to a group of copper sheets at the lower end of a lamp base by the conductive wire. When the lamp cover rotates, two groups of copper sheets are discontinuously contacted, and the bulb flashes. The surface of the lamp cover has patterns, and the lamp cover can also be made into various stereo models so as to add the interests of playing.

Description

Hold flash of light and change lamp

The utility model relates to toy lamp, especially a kind ofly rely on staff effect rotation, and lamp is changeed in the flash of light of holding of sending passage of scintillation light.

At present, general toy lamp kind for recreation is more, portable sling type cage lamp is arranged haply and hold fixed torch lamp two big classes.All adopt the common flashlight lighting theory, join the transparent lamp shade of a different shaping.The luminous weighing apparatus of these toy lamps is fixed, can not glimmer, and lampshade can not rotate yet, and is interesting relatively poor.

The purpose of this utility model is the deficiency at above-mentioned toy lamp, provides a kind of simple in structure, lean on the strength of staff to make the lampshade rotation, and lamp is changeed in the flash of light of holding of discovery passage of scintillation light.

Holding flash of light commentaries on classics lamp profile is made up of lampshade, lamp stand and handle.An in succession end of tooth bar of the pushing block of lamp stand side, the tooth bar other end is equipped with stage clip, and double crosslinking gear shaft in the lamp stand and monodentate wheel shaft are formed transmission mechanism together with tooth bar; Monodentate wheel shaft one end stretches out the lamp stand upper end, and the lamp socket lower end of dressing up one with lampshade is enclosed within on this axle that stretches out, and bulb is equipped with in the lamp socket upper end; Handle and lamp stand fuse, and battery is housed in the handle, have lead the battery secondary to be switched on two copper sheets of lamp stand upper end respectively; Bulb two utmost points also have lead to be switched to respectively on other two copper sheets of lamp socket lower end.

The utility model can promote the tooth bar motion by the thrust of thumb, drives transmission mechanism, makes the lampshade rotation, makes battery discontinuously to bulb powered, flashes.Be furnished with transparent lamp shades various patterns or various three-dimensional contourings, in rotation, show passage of scintillation light, novel and lively, increased the interest and the imagination of amusement.Also tempered the strength of hand when playing, be of value to physically and mentally healthy.It is all suitable toy of adult and child.

The utility model is held concrete structure and the principle that lamp is changeed in flash of light, is provided by the following drawings and embodiment.

Fig. 1 holds the structural representation cutaway view that lamp is changeed in flash of light.

Fig. 2 is the cutaway view of A shown in Figure 1 position.

Fig. 3 is the cutaway view of B shown in Figure 1 position.

Fig. 4 is the view of C direction shown in Figure 1.

Embodiment:

The contrast accompanying drawing refers to hold handle 9, thumb press pushing block 7 with four outside one hand or both hands (child) thumb, drive tooth bar 6 moving linearlies that fuse with pushing block 7, the pinion of tooth bar 6 and double crosslinking gear shaft 5 makes double crosslinking gear shaft 5 from Fig. 3 direction, counter rotation.And this moment double crosslinking gear shaft 5 the gears engaged of gear wheel and monodentate wheel shaft 12, make monodentate wheel shaft 12 from Fig. 3 direction, the clockwise direction rotation.When tooth bar 6 is pulled to when running into lamp stand 8 medial surfaces, loosen the thumb of pushing pushing block 7, tooth bar 6 and pushing block 7 return to original position under stage clip 11 effects.Because two ends of double crosslinking gear shaft 5 are to be contained in the top and bottom slotted hole 13 of lamp stand 8, when tooth bar 6 is return, double crosslinking gear shaft 5 is taken to the direction from Fig. 2, on the position that slotted hole 13 is kept right, and make double crosslinking gear shaft 5 from Fig. 3 direction, turn clockwise, at this moment, the gear of the gear wheel of double crosslinking gear shaft 5 and monodentate wheel shaft 12 leaves, and can not be with and change monodentate wheel shaft 12.Use thumb press pushing block 7 again, double crosslinking gear shaft 5 is brought to the direction from Fig. 2 again, and on the position that keeps left in slotted hole 13, the gear wheel of double crosslinking gear shaft 5 and the gear of monodentate wheel shaft 12 mesh again at this moment, and make monodentate wheel shaft 12 from Fig. 3 direction, remain and turn clockwise.

Push continuously and loosen pushing block 7, make monodentate wheel shaft 12 all the time towards a direction rotation.Monodentate wheel shaft 12 1 ends stretch out the last plane of lamp stand 8, drive the lamp socket 3 be enclosed within on the monodentate wheel shaft 12, then the lampshade 1 and the bulb 2 that are fitted together with lamp socket 3, also all the time towards a direction rotation.The rotating speed of lampshade 1 is urged with pushing block 7 and the speed loosened is directly proportional.

The both positive and negative polarity of the battery 10 in the handle 9 is switched on two one group of copper sheets 4 that are fixed on lamp stand 8 upper surfaces by lead respectively by through wires hole 14; Two utmost points of bulb 2 also are switched on two one group of copper sheets 4 that are fixed on lamp socket 3 lower surfaces by lead respectively.During lampshade 1 rotation, two groups of copper sheets 4 contact by phased manner, and bulb 2 is switched on by phased manner, flash.Flashing speed is directly proportional with the rotating speed of lampshade 1.

When lampshade 1 does not change, two groups of copper sheet 4 contacts, then bulb 2 is long bright.Otherwise then do not work.When not playing, lampshade 1 can take off in addition easily to be put.

Claims

A kind of flash of light commentaries on classics lamp of holding comprises the lampshade 1 that bulb 2 is housed, and the lamp stand 8 and the handle 9 that battery 10 is housed of tooth bar 6 and transmission mechanism is housed; It is characterized in that: a gear on tooth bar 6 and the double crosslinking gear shaft 5 meshes all the time, two ends of double crosslinking gear shaft 5 are contained in two slotted holes 13 on the lamp stand 8, whether another gear on the double crosslinking gear shaft 5 and monodentate wheel shaft 12 cog meshes, and depends on the position of double crosslinking gear shaft 5 in slotted hole 13; Tooth bar 6 one ends are equipped with stage clip 11; Two utmost points of battery 10 and bulb 2 are received respectively by lead on the copper sheet 4 of two groups of energy discontinuity contacts when lampshade 1 rotates.
