Description
Technical field
The utility model relates to beacon vehicle field more particularly to a kind of folding four-bar linkage structures for hydraulic beacon vehicle.
Background technique
The lamp stand part of beacon vehicle is the key position of entire beacon vehicle design, currently, hydraulic beacon vehicle on the market
Lamp stand part is using upright pusher structure or pulley hydraulic structure, this kind of structure is that one section of a section releases lamp stand, upper
Stability is poor during rising, and lifting height is lower, and appearance is also unsightly.
Utility model content
The applicant is directed to above-mentioned existing issue, has carried out Improvement, provides a kind of folding for hydraulic beacon vehicle
Four-bar linkage structure effectively realizes the at the uniform velocity stable rising of double leval jib.
Technical solution used by the utility model is as follows:
A kind of folding four-bar linkage structure for hydraulic beacon vehicle, including a pair of of Socket for lamp pole, in the pair of lamp stand base
One end one end pin joint with first lamp stand respectively of seat, the other end of each first lamp stand and one end pin of the 4th lamp stand
It connects；In other end one end pin joint with second lamp stand respectively of the pair of Socket for lamp pole, the other end of each second lamp stand
By the same pin shaft and the 4th lamp stand pin joint, sold in the one end for also passing through the same pin shaft and third lamp stand on each second lamp stand
Connect, the other end of the third lamp stand and the 4th lamp stand respectively with a pair of 5th lamp stand pin joint；Between a pair of of Socket for lamp pole also
Pass through a logical pin shaft and a pair of second lamp stand pin joint with the movable end of one end pin joint of hydraulic push rod, the hydraulic push rod.
Its further technical solution is:
The pair of Socket for lamp pole is connected to the upper surface of base disc.
The beneficial effects of the utility model are as follows:
The utility model structure is simple, easy to use, and the utility model makes each lamp stand uphill process using four-bar linkage structure
Stability it is good, lifting height can be rolled over when not in use according to actual production increase in demand or reduction, appearance looks elegant
It is folded to save space, effectively meet the use demand of client.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the status diagram of the utility model.
Wherein: 1, base disc；2, Socket for lamp pole；3, the first lamp stand；4, hydraulic push rod；5, the second lamp stand；6, third lamp
Bar；7, the 4th lamp stand；8, the 5th lamp stand；9, lamp group is irradiated.
Specific embodiment
Illustrate specific embodiment of the present utility model below.
As shown in Figure 1, a kind of folding four-bar linkage structure for hydraulic beacon vehicle includes a pair of of Socket for lamp pole 2, in a pair
One end of Socket for lamp pole 2 one end pin joint with first lamp stand 3 respectively, the other end and the 4th lamp stand 7 of each first lamp stand 3
One end pin joint；In other end one end pin joint with second lamp stand 5 respectively of a pair of of Socket for lamp pole 2, each second lamp stand 5
The other end is by 7 pin joint of the same pin shaft and the 4th lamp stand, in also passing through the same pin shaft and third lamp stand on each second lamp stand 5
The other end of 6 one end pin joint, third lamp stand 6 and the 4th lamp stand 7 respectively with a pair of 5th lamp stand, 8 pin joint, as shown in Figure 1, one
The head of 5th lamp stand 8 is connect with mounting bracket, is separately connected irradiation lamp group 9 by multiple connectors in mounting bracket,
Between a pair of of Socket for lamp pole 2 also with one end pin joint of hydraulic push rod 4, the movable end of hydraulic push rod 4 by a logical pin shaft with
5 pin joint of a pair of second lamp stand.As shown in Figure 1, above-mentioned a pair of Socket for lamp pole 2 is connected to the upper surface of base disc 1.
The specific work process of the utility model is as follows:
As shown in Figure 1 and Figure 2, started by the output end of hydraulic push rod 4 and a pair of second lamp stand 5 is driven to act, due to each the
One end of two lamp stands 5 is with 2 pin joint of Socket for lamp pole, therefore the second lamp stand 5 is using the pin shaft as pivot point, due to the second lamp stand
5 one end and 7 pin joint of the 4th lamp stand, therefore the movement of the 4th lamp stand 7 is driven when the second lamp stand 5 is rotated with pin shaft, due to the 4th
One end pin joint of the end of lamp stand 7 and the first lamp stand 3, and the other end of the first lamp stand 3 and 2 pin joint of Socket for lamp pole, therefore the
Four lamp stands 7, which act, simultaneously drives the first lamp stand 3 to be lifted, and similarly, is influenced by the second lamp stand 5, and third lamp stand 6 is also taken advantage of a situation lifting, by
Third lamp stand 6 and the 4th lamp stand 7 drive a pair of 5th lamp stand 8 movement jointly, to realize the cloth in the horizontal direction of irradiation lamp group 9
It sets and is illuminated.The utility model structure is simple, easy to use, and the utility model rises each lamp stand using four-bar linkage structure
The stability of process is good, and lifting height when not in use can may be used according to actual production increase in demand or reduction, appearance looks elegant
Space is saved to fold, effectively meets the use demand of client.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
