It sets in the presence of design unreasonable, poor work stability, using insecure problem, is further improved.In view of the above-mentioned problems, being permitted
More manufacturers and knowledgeable people have put into a large amount of man power and material and have developed and develop, but there has been no comparatively ideal so far
Product emerges.
Invention content
To overcome deficiencies of the prior art, the purpose of this utility model be to provide it is a kind of it is reasonable in design,
Simple to operate, safe and reliable, stability and using effect is good, lawn machine prefastening seat switch actuating mechanism.
The utility model solves technical solution used by above-mentioned technical problem, it includes the front support being fixed on the rack
Frame and back support rod, seating pad, cushion, switch, switch seat board, left and right seat spring, cushion is fixed on seating pad, described
Cushion prelaminar part is hinged on by axis pin screw on the front support frame of rack, and cushion postlaminar part, which is fixed with to slide up and down with sliding sleeve, matches
The traveller of conjunction, switch are fixed on switch seat board, and the contact of switch is matched with seating pad, are fixed on switch seat board and are sleeved on cunning
Sliding sleeve on column is equipped with preloading spring between seating pad and switch seat board；On cushion nobody when preloading spring jack up seating pad
It is detached with the contact of switch, switch normally-closed contact is connected, and normally opened contact disconnects working power；Seating pad compresses when someone on cushion
The contact of preloading spring and touching switch, switch normally-closed contact disconnect, and normally opened contact connects working power.
The further scheme of the utility model, the lower part of the left and right seat spring correspond to the back support rod for being fixed on rack
On, upper part corresponds to the both sides for being supported on switch seat board by spring base.
The head of the further scheme of the utility model, the traveller is equipped with screw thread and is connected with nut, and rotating nut can
To adjust the pretightning force of idle stroke and preloading spring between seating pad and switch.
With the above structure, it has the following advantages compared with the prior art or effect：First, due to the contact and seat of switch
Backing plate matches, and switchs and is fixed with the sliding sleeve being sleeved on traveller on seat board, is equipped between seating pad and switch seat board and pre-tightens bullet
Spring, when on cushion nobody when preloading spring jack up seating pad detached with the contact of switch, switch normally-closed contact connect, normally opened contact
Disconnect working power；Seating pad compression preloading spring and the contact of touching switch, switch normally-closed contact disconnect when someone on cushion,
Normally opened contact connects working power, stability and good reliability, to meet safety, ensures using installation.Second is that due to left and right
Seat spring is supported on the both sides of switch seat board, and preloading spring can play the role of controlling switch connection or disconnection, left and right seat
Chair spring can play cushioning buffer effect；Third, the nut on traveller head, can not only adjust between seating pad and switch
Idle stroke, and the pretightning force of preloading spring can be adjusted.
Description of the drawings
Fit structure schematic diagram when Fig. 1 is someone on the utility model cushion.
Fig. 2 is the A-A cross-sectional views of the utility model Fig. 1.
Wherein 1 cushion, 2 axis pin screws, 3 racks, 4 or so seat springs, 5 spring bases, 6 switch seat boards, 7 switches, 8 sit
Backing plate, 9 travellers, 10 sliding sleeves, 11 preloading springs, 12 back support rods, 13 front support frames.
Specific implementation mode
It is a kind of specific embodiment party of lawn machine prefastening seat switch actuating mechanism of the utility model shown in Fig. 1 and Fig. 2
Case, it include the front support frame 13 being fixed in rack 3 and back support rod 12, seating pad 8, cushion 1, switch 7, switch seat board 6,
Left and right seat spring 4, cushion 1 are fixed on seating pad 8, and 8 front of seating pad is hinged on rack 3 by axis pin screw 2
Front support frame 13 on, 8 rear portion of seating pad is fixed with the traveller 9 that cooperation is slided up and down with sliding sleeve 10, and switch 7 is fixed on switch base
On plate 6, the contact of switch 7 is matched with seating pad 8, is switched and is fixed with the sliding sleeve 10 being sleeved on traveller 9 on seat board 6, in cushion
It is equipped with preloading spring 11 between plate 8 and switch seat board 6；When on cushion 1 nobody when, the elastic force of preloading spring 11 jacks up seating pad 8
