Embodiment
Referring to Fig. 1, Fig. 2, present embodiment is made up of head 1, rubber ring 2, snap ring 3 and fastening ring 4, and head 1 is provided with some circle outside threads 13, has four head recess 11 on the outside thread 13, and head recess 11 is perpendicular to head bottom disc 12; Snap ring 3 is circular, and its inner ring is provided with the protruding pin 31 of snap ring of four evaginations, and the size of the protruding pin 31 of snap ring and shape and head recess 11 are complementary, and the outer ring of snap ring 3 is provided with a snap ring self-locking block 32, and snap ring self-locking block 32 is structure as a whole with snap ring 3; Fastening ring 4 also is circular, and its inner ring is provided with the internal thread 42 that some circles and outside thread 13 are complementary, and its outer ring is provided with several evenly distributed fastening ring teeth 41, and the size and the shape of snap ring self-locking block 32 and fastening ring tooth 41 are complementary.
During installation, earlier rubber ring 2 is inserted in the head 1 that has head recess 11 and develops with head bottom disc 12, then before panel 5 with in the head 1 insertion mounting hole, in panel 5 back snap ring 3 and fastening ring 4 are installed successively afterwards.When snap ring 3 is installed, as shown in Figure 2,, and make snap ring 3 develop panel 5 with the protruding pin 31 of the snap ring of snap ring 3 head recess 11 of head 1 of packing into accordingly; Because the effect of contraction between protruding pin 31 of snap ring and the head recess 11, snap ring 3 can only move on the axial direction of head 1, and can not rotate.Then precession fastening ring 4 combines itself and snap ring 3 by outside thread 13 and internal thread 42.
As shown in Figure 3, in installation process, utilize the elasticity of material and rubber ring 2, by screwing fastening ring 4, the fastening ring tooth 41 that makes fastening ring 4 and the snap ring self-locking block 32 mutual inlay cards of snap ring 3 are together, because the directivity between snap ring self-locking block 32 and the clamp ring tooth 41, fastening ring 4 can not freely rotate towards the thread looseness direction, thereby makes total realize screw thread self-locking fixed function.
Pass through the interaction of head 1, snap ring 3 and fastening ring 4 like this, make whole neck thread self-locking fixing device can both closely be fixed on the panel 5 down in rugged environment (as vibration environment etc.), compare with the panel fastening means of existing switch or tutorial light, have using scope widely.
As shown in Figure 4, when needing this device of dismounting, only need break the snap ring self-locking block 32 of snap ring 3 off with the fingers and thumb, its clamp ring tooth 42 with fastening ring 4 is separated, just can freely screw out fastening ring 4, reach the purpose of dismounting.
This neck thread self-locking fixing device can be applied on industrial switch or the tutorial light.When being applied on the switch, the supporting use of this device and housing, contact block (band lamp ﹠ lantern switch also supporting have power pack), its middle shell, contact block, power pack are prior art.When being applied on the tutorial light, itself and housing, the supporting use of power pack, its middle shell and power pack are prior art.
When being applied on the switch head, push-button switch head, band button switch head, mushroom-like push-button switch head, key operation head, rotary switch head and tight guard's valve head etc. are arranged specifically; When being applied on the tutorial light head, flat shape tutorial light head and spherical tutorial light head are arranged specifically.
Head 1 in this neck thread self-locking fixing device specifically has two kinds of Placements when cooperating with housing, a kind of is that mode by the self-locking collar is with head 1 and housing chucking (being self-locking collar clamping type), as Fig. 5～push-button switch shown in Figure 7, Fig. 8～mushroom-like push-button switch shown in Figure 10, Figure 11～key operation shown in Figure 13, Figure 14～tight guard's valve shown in Figure 16, Figure 17～rotary switch shown in Figure 19, Figure 20～band button switch shown in Figure 22, Figure 23～flat shape tutorial light shown in Figure 25, Figure 26～spherical tutorial light shown in Figure 28, I wherein are partly for being this neck thread self-locking fixing device.Another kind is directly to tighten (being non-self-locking collar clamping type) by interconnected self-locking mode between head 1 and the housing, as the band button switch of the rotary switch of the tight guard's valve of the key operation of the mushroom-like push-button switch of the push-button switch of Figure 29～shown in Figure 31, Figure 32～shown in Figure 34, Figure 35～shown in Figure 37, Figure 38～shown in Figure 40, Figure 41～shown in Figure 43, Figure 44～shown in Figure 46, Figure 47～flat shape tutorial light shown in Figure 49, the spherical tutorial light shown in Figure 50～Figure 52, I wherein is partly for being this neck thread self-locking fixing device.
