The concrete start process and the principle that lock condition checkout gear 1 about the screw in the present embodiment are detailed later.
Fig. 4 with Figure 5 shows that the illustrative view that locks condition checkout gear 1 according to the screw of a preferred embodiment of the present utility model.Please a And referring to figs. 2 to Fig. 5.
In present embodiment, a plurality of screws lock condition checkout gear 1 and can be arranged on the check-out console (figure does not show).When detecting, the operator can be positioned over object under test (figure does not show) on the check-out console.Wherein, object under test has one side that screw locks the hole towards check-out console, and the screw on the object under test locks the hole and corresponds respectively to screw and lock condition checkout gear 1.Then, utilize the indicating effect of first indicating member 16 and second indicating member 18 (as shown in Figure 2), the operator can judge that the screw of object under test locks the state that locks of screw in the hole.
Below to lock the state of locking that condition checkout gear 1 detects a screw with a screw be that example illustrates that it detects principle.
In present embodiment, when not locking screw (promptly leaking the lock state) on the object under test, screw locks condition checkout gear 1 and is in original state.At this moment, the pressing part 101 of detecting unit 10 is not subjected to pushing of screw, and depression bar 100 utilizes the elastic force effect of first elastic component 102 to be in initial position.Simultaneously, conducting element 111 utilizes the effect of second elastic component 112 also to be in initial position, and this utilizes the effect of the 3rd elastic component 122 also to be in initial position to the conduction body of rod 121.
Particularly, in present embodiment, when depression bar 100 was in initial position, as shown in Figure 3, the first 1003 of depression bar 100 was positioned at the top of the conducting element 111 of first conductive unit 11, and promptly the first 1003 of depression bar 100 does not contact with conducting element 111.Simultaneously, the second portion 1004 of depression bar 100 does not also contact with second conductive unit 12.In other words, this of first 1003 and conducting element 111 and second portion 1004 and second conductive unit 12 be not to all having electrical connection between the conduction body of rod 121.At this moment, testing circuit is not switched on, and first indicating member 16 and second indicating member 18 all can not send indication.Thus, the operator can detect the state that screw leaks lock.
In present embodiment, when normally locking screw on the object under test, screw locks condition checkout gear 1 and is in first compressive state.At this moment, utilize the action of gravity of object under test self, the pressing part 101 of the screw meeting pressing detecting unit 10 on the object under test, thus make depression bar 100 move first distance.
Particularly, in present embodiment, as shown in Figure 4, and after depression bar 100 moves first distance, the conducting element 111 of first's 1003 contacts, first conductive unit 11 of depression bar 100, promptly first 1003 electrically connects conducting element 111.At this moment, utilize the elastic reaction of second elastic component 112, conducting element 111 can keep can not dropping from through hole 131 with electrical contact of first 1003.In addition, the second portion 1004 of depression bar 100 still contact the conduction body of rod 121 with this of second conductive unit 12, and promptly second portion 1004 does not have electrical connection with this to conducting electricity the body of rod 121.Thus, first 1003 and conducting element 111 turn-on powers 14 and first indicating member 16 (as shown in Figure 2) make the indicating member 16 of winning send indication.In this, it is luminous to be pilot lamp L1.Thus, the operator can judge that object under test normally locks screw.
In present embodiment, when the screw on the object under test during for floating lock state (be screw do not lock fully to screw lock the hole), screw locks condition checkout gear 1 and is in second compressive state.At this moment, utilize the action of gravity of object under test self, the pressing part 101 of the screw meeting pressing detecting unit 10 of object under test come-up lock makes depression bar 100 move second distance.Since during the floating lock of screw screw protrude from height that screw locks the hole when normally locking greater than screw screw protrude from the height that screw locks the hole, therefore, in this, second distance is greater than first distance.
Particularly, in present embodiment, as shown in Figure 5, after depression bar 100 moved second distance, the first 1003 of depression bar 100 broke away from the electrical connection with conducting element 111.That is, first 1003 moves to the below of conducting element 111, and conducting element 111 returns back to initial position under the elastic force effect of second elastic component 112.In addition, this of the second portion 1004 of depression bar 100 and second conductive unit 12 electrically connects the conduction body of rod 121.Thus, second portion 1004 and this make second indicating member 18 send indication to the conduction body of rod 121 turn-on powers 14 and second indicating member 18.In this, it is luminous to be pilot lamp L2.Thus, the operator can detect the state of the floating lock of screw.
In present embodiment, after detecting end, utilize the elastic force effect of first elastic component 102, depression bar 100 returns back to initial position.Utilize the effect of the 3rd elastic component 122, this returns back to initial position to the conduction body of rod 121.Utilize the elastic force effect of second elastic component 112, conducting element 111 returns back to initial position.
In sum, in the utility model preferred embodiment, the screw of object under test has different height when difference locks state.Thus, when screw leaked lock, because the pressing part 101 of detecting unit 10 can not be pressed, so the first 1003 of detecting unit 10 contact with conducting element 111 and second portion 1004 does not contact conducting electricity the body of rod 121 with this of second conductive unit 12.When screw normally locks or float lock, the first 1003 of detecting unit 10 can electrically connect that conducting elements 111 or second portion 1004 can electrically connect second conductive unit 12 this to the conduction body of rod 121, thereby the state that locks by first indicating member 16 and second indicating member, 18 indication screws.So, utilize the screw in the utility model to lock condition checkout gear 1, but the floating lock of the screw of synchronous detection object under test or leakage lock state.In addition, it is time saving and energy saving not only to operate, and has reduced cost.
Though the utility model discloses as above with preferred embodiment; yet it is not in order to limit the utility model; anyly be familiar with this operator; in not breaking away from spirit and scope of the present utility model; when can making all changes that is equal to or replacement, therefore protection domain of the present utility model is when looking being as the criterion that claims define.
