Buddhist nun's device it is stuck.
Utility model content
The technical problems to be solved in the utility model is：Overcome in the prior art damping chip damper to annular tolerance compared with
The technical problem of difference, provides a kind of valveless sheet type damping device.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of valveless sheet type damping device, including shell and the sliding that is slidably connected in the middle part of shell
Bar is fixed with damping block on the sliding bar, is hollow structure inside the damping block, the damping block is internally provided with one
The top of the groove of annular, the groove is open in the axial end portion of damping block, is arranged in the axial end portion opening of damping block
There is separating plate, gather through-hole on separating plate, and the two side of the groove is arcuate structure, and the bottom array of the groove is provided with
The top of several damping oil holes, the damping oil hole includes an inlaid hole, the inlaid hole towards the side inside damping block
For hemisphere planar, several hollow beads corresponding with aforementioned damping oil hole are provided in the damping block；The outer wall of damping block and resistance
It is slidably connected between Buddhist nun's device outer casing inner wall.
There are one connection rings for setting on the outer wall of the shell as a further improvement of the utility model, even
It connects and is slidably connected between ring and shell inner wall, be inlaid between the inner wall of the connection ring and the outer wall of shell
The rubber buffer circle of several annulars.
The separating plate is reticular structure as a further improvement of the utility model,.
A screw rod is further fixed on the sliding bar as a further improvement of the utility model, the screw rod passes through
The middle part of damping block, the bottom of the screw rod, which corresponds to damping block and is provided with the side of damping oil hole, fixes that there are one baffles, described
There are one pressing sleeve, the separating plate is pressed on the opening of damping block by pressing sleeve for the other end setting of screw rod.
The position between the damping oil hole is provided with drawing for several cones as a further improvement of the utility model,
Pilot rises.
The utility model has the beneficial effects that：
1, the utility model is realized by several pearls realizes damping oil flow rate to the partial closure of array damping oil hole
Control because being hollow pearl, can will not be too fast with pearl the bottom for sinking to damping block, but with the stream of damping oil
The dynamic bottom for being brought into damping block, to realize the closing of damping oil hole, this structure is compared to valve block, it is not easy to it damages,
Steel ball or bead can be used to replace, materials are simple, and manufacturing cost is low.
2, rubber buffer circle can realize the mobile cushioning between damping block and connection ring when damper velocity is too fast,
Prevent the breakage of damping block.
3, this structure integrally carries out locking fixation using screw rod, is readily disassembled cleaning damping oil hole and replaces steel ball.
4, guide hump can facilitate steel ball to enter in damping oil hole, improve the sensitivity of damper.

Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figure 1, the utility model is a kind of valveless sheet type damping device, including shell and it is slidably connected to
Sliding bar in the middle part of shell is fixed with damping block on the sliding bar, is hollow structure inside the damping block, described
Damping block is internally provided with an annular groove, and the top of the groove is open in the axial end portion of damping block, in damping block
Axial end portion opening be provided with separating plate, separating plate is reticular structure；A screw rod, institute are further fixed on the sliding bar
State the middle part that screw rod passes through damping block, the bottom of the screw rod corresponds to damping block and is provided with there are one the side fixations of damping oil hole
Baffle, there are one pressing sleeve, the separating plate is pressed on the opening of damping block by pressing sleeve for the other end setting of the screw rod；Institute
The two side for stating groove is arcuate structure, and the bottom array of the groove is provided with several damping oil holes, the damping oil hole
Top includes an inlaid hole towards the side inside damping block, and the position between the inlaid hole is provided with several cones
Guide hump, the inlaid hole are hemisphere planar, are provided in the damping block several corresponding with aforementioned damping oil hole hollow
Pearl；It is slidably connected between the outer wall and shell inner wall of damping block.
