Abstract
The utility model provides a manual/electric switch mechanism of an explosion-preventing electric device for a fire monitor, belonging to the technical field of fire-fighting equipments. The object of the utility model is to provide a manual/electric switch mechanism of an explosion-preventing electric device for a fire monitor, so that the product using the manual/electric switch mechanism has less volume and light weight. The utility model has the main improvement that in the electric state, the distance between the upper end face of the upper sleeve of a clutch and the end face of the shaft bottom of a manual shaft is the height of the claw of the clutch, the clutch boss is lower than the upper end face of the upper sleeve of the clutch by the height of the claw of the clutch, thereby the distance between the manual shaft and the upper sleeve of the clutch is reduced to the minimum state.
Description
Technical field
The utility model belongs to the fire-fighting equipment field, particularly relates to a kind of hand/electronic switching mechanism that is applicable to fire monitor with the anti-explosion electric device.
Background technology
Fire monitor is the electric device that fire monitor producer adopts for the 360 degree revolutions that realize barrel with the anti-explosion electric device, and it generally has manually and electronic two kinds of patterns.Manually and the switching between the electric model rely on hand/electronic switching mechanism to realize.In the design of prior art, hand/electronic switching mechanism mainly comprises the switching handle, shift fork, small clevis pin with head, up-and-down rod, clutch, overlap on the clutch, as shown in Figure 1, when motoring condition, the upper end surface of overlapping on the end face of clutch boss and the clutch is in same plane, and manually clearance distance is a twice toothpick height between the upper surface of overlapping on axle toothpick end face and the clutch.When switching to manual state, clutch need be lifted twice toothpick height, make the end face of boss exceed the upper surface twice toothpick height that overlaps on the clutch, make the clutch boss and the toothpick of manual axle mesh, rotate manual handle, manually overlap on the axle drive clutch, cover drives clutch by the engagement of keyway and clutch boss on the clutch, and clutch drives driving shaft work.But the problem that this prior art exists is on volume also to become excessive at corresponding fire monitor with the anti-explosion electric device because the upper end surface of overlapping on the end face of clutch boss and the clutch makes in same plane, and weight becomes weight.
The utility model content
The purpose of this utility model provides the hand/electronic switching mechanism of a kind of fire monitor with the anti-explosion electric device, and it can make the smaller volume of application product in design, weight saving.
The technical solution of the utility model is: a kind of fire monitor is with the hand/electronic switching mechanism of anti-explosion electric device, comprise the switching handle, shift fork, small clevis pin with head, up-and-down rod, clutch, overlap on the clutch, be connected with shift fork on the described switching handle, two arms of shift fork are equipped with small clevis pin with head, the small clevis pin with head of its middle and lower part connects up-and-down rod, and in the groove of the end difference embeddeding clutch of small clevis pin with head, clutch stretches in the keyway that overlaps by its boss and matches with last cover, cover and ball bearing stationary fit on the clutch, described mechanism is one times of clutch toothpick height between the axle bottom face of upper surface of overlapping on the clutch and manual axle when motoring condition, and the clutch boss is lower than the upper surface one times of clutch toothpick height that overlaps on the clutch; When described mechanism switches to manual state, move and switch handle 1 drive shift fork 2, clutch is lifted twice toothpick height under the shift fork effect, and the clutch boss exceeds the upper surface twice toothpick height that overlaps on the clutch, clutch boss and the manually toothpick engagement of axle.
Technique scheme can further be improved to: described clutch also is set with a spring.
The beneficial effects of the utility model are: by dwindling the distance between the cover on manual axle and the clutch, make both distances reach minimum state, thereby make that the volume of applied product is dwindled, saved the space, alleviated weight.

Fig. 2 is the utility model overall structure schematic diagram.
Structural representation when Fig. 3 is the utility model manual state.
Fig. 4 is the structural representation of the utility model when motoring condition.
The specific embodiment
Below in conjunction with accompanying drawing, technology contents of the present utility model is further elaborated.
As shown in Figure 2, a kind of fire monitor comprises and switches handle 1, shift fork 2 with the hand/electronic switching mechanism of anti-explosion electric device, small clevis pin with head 3, up-and-down rod 4, clutch 5 overlaps 6 on the clutch, be connected with shift fork 2 on the described switching handle 1, two arms of shift fork 2 are equipped with small clevis pin with head 3, and the small clevis pin with head of its middle and lower part connects up-and-down rod 4, in the groove of the end difference embeddeding clutch 5 of small clevis pin with head 3.Clutch 5 stretch on the clutch by its boss 7 in the keyway of cover 6 with clutch on overlap and matches cover 6 and ball bearing stationary fit on the clutch.As shown in Figure 3, during motoring condition, be the height of one times of clutch toothpick 9 between the axle bottom face of the upper surface of cover 6 and manual axle 8 on the clutch, clutch boss 7 is lower than the height of the one times of clutch toothpick 9 in upper surface of cover 6 on the clutch.
Be essential to change to manual state the time in this mechanism, move and switch handle 1 and drive shift fork 2, under the shift fork effect, clutch 5 meshes with tooth embedding 10 disengagings on the turbine 12, be lifted the height of twice clutch toothpick 9, therefore clutch boss 7 exceeds one times of toothpick height in upper surface of cover 6 on the clutch, and then clutch boss 7 and manually toothpick 11 engagements of axle 8.The maintenance of this state is erecting by up-and-down rod 4.Rotate manual handle, manually overlap on the axle drive clutch, cover drives clutch by the engagement of keyway and clutch boss 7 on the clutch, and clutch drives driving shaft work.
When motoring condition need switch to manual state, only need press automatically controlled button and turbine 12 be rotated drive up-and-down rods 4 and, and then under the effect of the spring 13 of clutch suit, clutch be fallen to finish the engagement of motoring condition.
The utility model dwindles the distance between the cover on manual axle and the clutch than prior art, makes both distances reach minimum state, thereby so that the volume of applied product is dwindled, has saved the space, has alleviated weight.
Claims (2)
1. a fire monitor comprises the switching handle, shift fork with the hand/electronic switching mechanism of anti-explosion electric device, small clevis pin with head, up-and-down rod, clutch, overlap on the clutch, be connected with shift fork on the described switching handle, two arms of shift fork are equipped with small clevis pin with head, and the small clevis pin with head of its middle and lower part connects up-and-down rod, in the groove of the one end difference embeddeding clutch of small clevis pin with head, clutch stretches in the keyway that overlaps by its boss and matches with last cover, and cover and ball bearing stationary fit on the clutch is characterized in that:
Described mechanism is one times of clutch toothpick height between the axle bottom face of upper surface of overlapping on the clutch and manual axle when motoring condition, and the clutch boss is lower than the upper surface one times of clutch toothpick height that overlaps on the clutch;
