Description
Technical field
The utility model is related to a kind of lifting gear, the combination of specifically a kind of jack and security bracket.
Background technology
Jack, can be by top pallet in stroke as the essential lifting gear of other machinery maintenances of vehicle
Interior jacking weight.In practical operation, automobile is first jacked up into certain altitude using jack, branch is then placed under automobile chassis
The security bracket of support, finally takes out jack.Since the Support Position of security bracket and the jack-up position of jack be not same
The variation of one position, Support Position can cause automobile to shake, and have security risk, be easy to happen personnel and damaged vehicle
Accident.
Utility model content
The purpose of the utility model is to overcome the deficiency in above-mentioned background technology, a kind of jack and security bracket branch are provided
Support point overlaps the lifting gear used, which should ensure that security bracket support is firm, while also have easy to operate
The characteristics of.
The technical solution of the utility model is：
A kind of jack overlaps the lifting gear used with security bracket supporting point, and jack therein includes that wheel is housed
Pedestal, Support bracket parallelogram mechanism, installation in the base with push parallelogram mechanism oil pump component, drive
Make that oil pump pump core in oil pump component moves press hand and the handle of hand is pressed in connection；It is characterized in that：The bracket is horizontal cloth
The U-shaped bracket set, the distance between U-shaped bracket two-arm are more than the top width of security bracket, so that top can pass through U-shaped up and down
Space among bracket carries out operation.
The jack further includes the movable tray for being movably placed on bracket top.
The parallelogram mechanism is hingedly formed successively by bracket, crane arm, connecting rod and pedestal wallboard.
The top of two crane arms is hinged commonly through an articulated shaft and U-shaped bracket, and the top of two connecting rods is then respective
It is hinged with an arm of U-shaped bracket respectively by an articulated shaft.
Hand, connecting rod and the crane arm pressed rotationally is hinged on pedestal wallboard.
The utility model has the beneficial effects that：
The utility model is simple in structure, easy to operate, and the top of security bracket can be interspersed in the bracket of jack,
So that the jack-up position of jack is overlapped with the Support Position of security bracket, security risk is eliminated, maintenance mans are effectively improved
The safety of work.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Fig. 2 is the occupation mode schematic diagram of the utility model.
Fig. 3 is the occupation mode schematic diagram (omitting movable tray) of the utility model.
Fig. 4 is the dimensional structure diagram of security bracket and movable tray mated condition.
Specific implementation mode
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
A kind of jack overlaps the lifting gear used with security bracket supporting point, and jack therein includes pedestal 1, support
Frame 2 (being used to support load), connecting rod 4, oil pump component (being omitted in figure), presses hand 5, movable tray 6 at crane arm 3.
The pedestal includes two blocks of wallboards 12, and the bottom of wallboard is mounted on for the wheel 11 of jack for moving.The company
The both ends of bar and crane arm are rotationally hinged between wallboard and bracket, and bracket, connecting rod, crane arm and wallboard form one
Parallelogram mechanism, it can be ensured that the top surface of bracket remains horizontal in the motion process of parallelogram mechanism
State.
For pushing the oil pump component of parallelogram mechanism motion to install in the base, (oil pump component includes oil cylinder and oil
Pump, oil pump are used for oil cylinder pump oil), it presses hand and is connected to handle (being omitted in figure) and the pump core of oil pump can be driven to move, pressing hand can
Rotationally it is hinged on wallboard.
The improvement of the utility model is：The bracket is U-shaped bracket, and U-shaped bracket is horizontally disposed, is open towards base length
The one end (press hand and the other end in base length direction is arranged) in direction, crane arm is rotationally hinged on U-shaped respectively with connecting rod
The both sides of bracket are (visible in figure：The top of two crane arms is hinged commonly through an articulated shaft 7 and U-shaped bracket；Two connecting rods
Top then each by a short axle 8 hinged, the axis coaxle of two short axles with an arm 2-1 of U-shaped bracket respectively).U-shaped
The distance between bracket two-arm is more than the top width of security bracket, and top carries out between can passing through U-shaped bracket two-arm up and down
Operation.The security bracket is common support tool；As shown in Figure 4:The security bracket usually by bearing, can move up and down vertically
Ground positions rack in the holder and drives the gear of drive rack to form by handle；The top of rack is the top 15 of V-arrangement,
Rack width and top it is of same size.
The occupation mode of the utility model has following two：
1, as shown in Figure 2；In use, movable tray is placed on bracket top, then automobile of jack-uping, then it will protect
Peace holder is moved in jack, so that the top of security bracket is interspersed in the space between U-shaped bracket two-arm and (is located at activity support
Below disk) and rising security bracket makes top withstand movable tray, finally falls jack；Movable tray is completely by ensuring public security at this time
Holder is supported, therefore the Support Position of automobile chassis does not change, and can still keep supporting & stablizing.
2, as shown in figure 3, being operated without using movable tray；Jack stand automobile and then security bracket is moved
It moves into jack, the top of security bracket is made to be interspersed in the space among U-shaped bracket direct jacking automobile chassis, same energy
It is enough accurately to support automobile chassis in bracket locations, still keep supporting & stablizing.
