Abstract
The utility model relates to a shock-absorbing device for a rear handle of a wind fire extinguisher. The utility model is arranged between a housing of a blower and the rear handle, a shock-absorbing rubber block is arranged in a cavity arranged on the housing of a blower, and the shock-absorbing rubber block is connected with the rear handle through bolts by means of nuts which are fixed in the shock-absorbing rubber block. The original rigid connection between the rear handle and the housing of a blower is changed into indirect elastic connection, which lightens the sense of vibration of the rear handle and enhance the operating comfort, besides, the blower is avoided to work for a long handle, and the shedding of the rear handle is also avoided.
Description
The utility model belongs to forest fire control equipment, relates in particular to a kind of wind fire-extinguisher.
The defensive position handle of existing wind fire-extinguisher is connected with bolting with Fan casing, in order to alleviate defensive position the judder that when blower fan is worked, produces, between Fan casing and defensive position handle, increased the yielding rubber pad, the yielding rubber pad is clamped in the middle of Fan casing and the back teach-by-doing under the fastening effect of bolt.Because Fan casing and engine are rigid attachment, when the vibration of engine was delivered to Fan casing, the defensive position that is connected with Fan casing by bolt was still strong the sense of shaking, and its damping effect is relatively poor, easily causes operating personnel's arm fatigue.Another shortcoming of this structure is that when blower fan work overlong time, nut is easily loosening, can make defensive position coming off, and brings very big inconvenience to operation.
The purpose of this utility model is to provide a kind of wind fire-extinguisher defensive position damping device, and the vibration sense of defensive position handle increases the comfortableness of operating when working to alleviate blower fan.
For achieving the above object, the employing technical scheme is as follows: the wind fire-extinguisher defensive position is damping device, between Fan casing and defensive position handle, contain a yielding rubber piece, particularly nut places yielding rubber piece inside, have bolt-inserting hole to communicate with nut on the yielding rubber piece, the yielding rubber piece places on the Fan casing in the cavity, and the defensive position handle is connected by bolt with the yielding rubber piece.
In addition, there is annular groove the outside of yielding rubber piece, and the cavity on the Fan casing is opening-like, and its opening part has the bayonet socket edge of matching with yielding rubber piece annular groove.Nut is fixed on the steel plate, together places yielding rubber piece inside with steel plate.
Below in conjunction with the embodiment accompanying drawing the utility model is described in detail.
Fig. 1 is the outer portion connecting structure figure of Fan casing and defensive position handle.
Fig. 2 is that defensive position is the internal structure schematic diagram of damping device.
By Fig. 1, Fan casing 1 links 3 with defensive position, and yielding rubber piece 2 is between Fan casing 1 and defensive position are 3.By Fig. 2, on Fan casing 1, be provided with cavity 11, yielding rubber piece 2 places cavity 11, there is nut 6 to reach the steel plate 5 that is fixed together with nut 6 in the inside of yielding rubber piece 2, has bolt-inserting hole 7 to communicate on the yielding rubber piece 2, annular groove 8 is arranged in the outside of yielding rubber piece 2 with nut 6, cavity 11 is opening-like, its opening part has the bayonet socket that matches with annular groove 8 along 9, and bayonet socket is clamped on yielding rubber piece 2 in the cavity 11 along 9, and block rubber 2 is deviate from from cavity 11 when avoiding vibrating.The taper type design of cavity 11 and yielding rubber piece 2 also is for fixing yielding rubber piece 2 better.Defensive position is fixedlyed connected 3 with nut 6 by bolt 4 with yielding rubber piece 2.The exposed parts of yielding rubber piece 2 is kept apart Fan casing 1 and defensive position to 3.Among Fig. 2, the nut in the yielding rubber piece 2 can be provided with several as required.Defensive position all adopts this kind shock-damping structure to 3 with two joint portions of Fan casing.
Because the yielding rubber piece separates defensive position handle and Fan casing fully, the connection of bolts and nuts is the compression shock absorption block rubber, and then compresses Fan casing indirectly, so the defensive position handle is not rigid attachment with connecting of Fan casing, but resilient connection indirectly.After engine luggine was delivered to Fan casing, defensive position reacted on yielding rubber piece inside to the sense of shaking that produces by bolt and nut again, makes it produce certain elastic deformation, alleviates thereby will vibrate greatly.
The utility model compared with prior art has the following advantages:
1, the defensive position handle is indirect resilient connection with Fan casing, and vibration is cut in yielding rubber piece inside A little less than, vibration sense alleviates greatly, has strengthened the comfortableness of operation.
2, because nut is fixed in yielding rubber piece inside, therefore, after long-term work can not cause Handgrip comes off.
Claims (3)
1, the wind fire-extinguisher defensive position is damping device, between Fan casing and defensive position handle, contain the yielding rubber piece, it is characterized in that nut places yielding rubber piece inside, there is bolt-inserting hole to communicate on the yielding rubber piece with nut, the yielding rubber piece places on the Fan casing in the cavity, and the defensive position handle is connected by bolt with the yielding rubber piece.
2, wind fire-extinguisher defensive position as claimed in claim 1 is characterized in that there is annular groove the outside of yielding rubber piece to damping device, and the cavity on the Fan casing is opening-like, and its opening part has the bayonet socket edge of matching with yielding rubber piece annular groove.
3, as claim 1,2 described wind fire-extinguisher defensive positions damping device, it is characterized in that nut is fixed on the steel plate, together insert yielding rubber piece inside with steel plate.
