Above-mentioned purpose of the present utility model technical scheme is that：A kind of folder of waterproof test mould
Locking structure, including mould in the sealing that alignment is arranged, the lower mould of sealing is close to, in sealing, mould is close to set with lower mould two side ends are sealed respectively
There are clamping plate one, clamping plate two, fixed using bolt between clamping plate one, clamping plate two, actively set on the clamping plate one, clamping plate two respectively
There are handle one, handle two, between handle one and handle two, be provided with pressure bar, pressure bar is respectively with handle one, handle two by connecting
Extension bar one, connecting rod two are articulated and connected.
By adopting above-mentioned technical proposal, by the clamping plate one, clamping plate for being close to seal upper mould, the lower mould two ends of sealing are arranged
Two, sealing upper mould and the lower mould two ends of sealing are compressed, blending bolt fastening limits the degree of freedom of its horizontal direction；Clamping plate one,
Arrange on clamping plate two two handles and arrange between can downwardly against the pressure bar of the upper mould of sealing, and press bar both sides respectively with
The handle of both sides is hinged by connecting rod one, connecting rod two, and during two handles are moved towards, pressure bar is subject to handle
First, the horizontal thrust and vertical thrust of handle two, handle one and handle two are offset to the horizontal component of pressure bar, and one He of handle
Handle two can be such that pressure bar moves straight down to the vertical component of pressure bar, to reach the effect of mould in crush seal.
Preferably, the clamping plate one, clamping plate two are provided with the horizontal shelf that can hold the lower mould of sealing.
By adopting above-mentioned technical proposal, without flat workbench, two clamping plates are carried can be tight with the lower mould of sealing
The horizontal shelf of laminating, can cause pressure bar to play optimal compression effect.
Preferably, the pressure bar side face is vertically provided with vertical slot one, vertical slot two respectively, equal respectively in vertical slot one, vertical slot two
The inner side for being transversely provided with multiple poles one, clamping plate one and clamping plate two evenly is correspondingly provided with multiple poles two, connecting rod one and connection
Two two ends of bar are provided with the circular hole coordinated with pole one, pole two.
By adopting above-mentioned technical proposal, by opening up circular hole at connecting rod two ends, set on pressure bar, handle respectively
The structure put and can be arranged circular hole, achievable connecting rod are hinged with handle, pressure bar respectively.Wherein, can be arranged on pressure bar
The structure of circular hole is the vertical shallow slot for being opened in pressure bar side face, the multiple poles of laterally homogeneous fixation in shallow slot, will connection
The circular hole of bar one end is enclosed within pole, and connecting rod can be rotated upwardly and downwardly relative to pole.Can arrange similar to this on the inside of handle
Be arranged circular hole structure, connecting rod two ends are respectively hinged on the inside of handle, the bar side that presses face, are so designed that, at two
During handle move toward one another, by above-mentioned articulated structure, you can force pressure bar to move downward so as to the upper mould pressure of sealing.
Preferably, the handle one, handle two are hingedly connected to clamping plate one, two top of clamping plate.
By adopting above-mentioned technical proposal, by the top that the root of two handles is articulated with clamping plate, two handles can
Rotate around hinged place, when two handles are rotated in opposite directions, the connecting rod being articulated between pressure bar and handle just can promote pressure
Bar is moved downward, to compress the upper mould of sealing.
Preferably, the clamping plate one, two top of clamping plate are respectively equipped with and are available for handle one, the groove one of the insertion of handle two, lead to
Groove two, groove one, two bottom of groove have the groove one of built-in gear, groove two again, gear central authorities be provided with from clamping plate one,
The axle that two surface of clamping plate is stretched out, shaft end are provided with knob, and handle one, two bottom of handle are equipped with the spur rack that can be engaged with gear
One.
By adopting above-mentioned technical proposal, the movable of two handles is limited using groove one, groove two, can be by groove
One and the width design of groove two must be slightly longer than handle width, therefore handle can be moved left and right in groove.In groove one and logical
Groove one that two bottom of groove opens up respectively, groove two for preventing drive mechanism, the moving left and right in groove with driving handle.
Driving structure is connected with the engagement of spur rack for gear, by arranging spur rack in handle base, then gear is inserted in groove,
Can by rotate gear come driving handle moving left and right in groove.And be fixedly installed in gear central authorities and reach from inside clamping plate
Axle outside cleat surface, and in rotating shaft set upper knob, drive gear can be facilitated to rotate.
Preferably, the clamping plate one, clamping plate two side faces are close to top end and are respectively equipped with through hole one, through hole two, handle one, handss
