Abstract
The utility model aims at providing a ball joint clamping device for an operation table, which can generate elastic deformation, and comprises a locking seat, a fixing block, a universal ball head, a locking block and a compression bolt, wherein a hollow cavity is arranged in the locking seat, the fixing block is fixedly installed at one end of the locking seat, the universal ball head and the locking block are arranged in the hollow cavity of the locking seat, the compression bolt is pressed on the locking block, and a disk spring is arranged at the position where the compression bolt is connected with the locking block. The ball joint clamping device has the advantages that the disk spring is arranged at the position where the compression bolt is connected with the blocking block, the compression bolt presses the disk spring firstly, and then presses the universal ball head, and the universal ball head is pre-pressed, so that the rigid compression process is changed into flexible compression process, and further an operator is more relax, and the operation is convenient.
Description
Technical field
This utility model relates to a kind of ball-joint clamping device that is used for operating-table.
Background technology
Clinically, the medical worker for easy to operate, needs position, the angle and direction of operating-table are regulated within the specific limits in the process of implementing operation sometimes.Usually use the universal ball end hold down gag in the prior art, realize the rotation of each parts on the operating-table.Described universal ball end hold down gag comprises locking bed, is fixedly installed in the fixed block of locking bed, universal ball end and latch segment in the locking bed, be pressed in the hold-down bolt on the latch segment and be fixed on the spanner that compresses of hold-down bolt end.The personnel of operation platform can rotatably compress spanner as required, and control is advanced in the hold-down bolt or gone out, and when advancing in the hold-down bolt, hold-down bolt is pressed on universal ball end on the ball cup by latch segment, and the operating-table parts are fixed; When hold-down bolt was gone out, hold-down bolt, latch segment, universal ball end, ball cup were separated from one another, and universal ball end can rotate arbitrarily in locking bed, and the operating-table parts are movable.With the degree of tightness of this institutional adjustment universal ball end, when realizing the universal rotation of operating-table mechanism, when hold-down bolt compressed universal ball end by latch segment, feel was jerky, and the operator requires great effort very much.Universal ball end only has two states of degree of tightness, when loosening, tighten bulb, and the deformation of bulb generation rigidity, it is stiff that the component locations that bulb supports switches, and has a strong impact on the service life of each parts.
Disk spring is that its characteristics are as follows: 1. rigidity is big with the washer type spring in metal blank or the truncated cone shape cross section that forms of forging and pressing blank, and the buffering vibration absorption ability is strong, can bear big load with small deformation, is suitable for the little occasion of axial space requirement.2. have the change stiffness characteristics, have the nonlinear characteristic of very wide scope.3. adopt different compound modes with same disk spring, spring performance is in very large range changed.Can adopt involutory, superimposed compound mode, also can adopt compound different-thickness, the compound mode of different sheet numbers etc.When a plurality of disk springs were superimposed, with respect to same distortion, spring number load more at most was big more.
The utility model content
The purpose of this utility model is to provide a kind of elastically-deformable ball-joint clamping device that is used for operating-table that takes place.Establish universal ball end and latch segment in the locking bed of cavity, the fixed block that is fixedly installed in locking bed one end, locking bed cavity in this utility model comprises, be pressed in the hold-down bolt on the latch segment, the junction of described hold-down bolt and latch segment is provided with disk spring.The number of described disk spring is one or more, and when the disk spring number was two or more, each disk spring made up in superimposed mode.Be provided with packing ring between described disk spring and the hold-down bolt.Described hold-down bolt one end is near latch segment, and the other end is provided with and compresses spanner.
Advantage of the present utility model is, junction at hold-down bolt and latch segment is provided with disk spring, hold-down bolt compression disk spring repress is earlier compeled universal ball end, universal ball end has a process that compresses in advance, make rigidity be packed together to the process that a flexibility compresses, make the operator more laborsaving, be convenient to operation; Gimbal suspension compresses, gets loose in the process, and stiff rigidity deformation no longer takes place, and has effectively prolonged the service life of each parts, reduces cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment is described.
As shown in Figure 1, establish universal ball end 3 and latch segment 4 in the locking bed 1 of cavity, the fixed block 2 that is fixedly installed in locking bed one end, locking bed cavity in this utility model comprises, be pressed in the hold-down bolt 5 on the latch segment 4, the junction of described hold-down bolt 5 and latch segment 4 is provided with disk spring 6.
The number of described disk spring can be one or more, and when the disk spring number was two or more, each disk spring made up in superimposed mode.Same disk spring adopts different compound modes, and spring performance is in very large range changed, and can adopt compound different-thickness, the compound mode of different sheet numbers etc.When a plurality of disk springs were superimposed, with respect to same distortion, spring number load more at most was big more.The number of disk spring and thickness in this utility model can make one's choice according to actual needs.
Be provided with packing ring 7 between described disk spring and the hold-down bolt.Described hold-down bolt one end is near latch segment, and the other end is provided with and compresses spanner 8, and compressing spanner can rotate, and is used to control hold-down bolt and advances in the cavity of locking bed or retreat.
This utility model generally belongs to the ball-joint impaction state at work, and this moment, operating-table or its each several part parts all were fixed.Under the ball-joint impaction state, hold-down bolt acts on disk spring by packing ring, disk spring generation elastic deformation, and the disk spring after the deformation acts on latch segment, and latch segment is tightly pushed down universal joint, makes operating-table or its parts maintain static.
When needs are adjusted the operating-table position, pull and compress spanner, hold-down bolt acts on disk spring by packing ring, disk spring recovers prototype gradually, latch segment has reduced gradually to the universal ball end thrust, separates post gap between locking bed and the universal ball end and becomes gradually greatly, and universal ball end can random rotation transformation direction, operating-table or its parts also just can adjusting positions, angle and direction, so just guaranteed the smooth transition when universal ball end is shifted one's position.
After operating-table or its component locations, angular adjustment are finished, the operator pulls and compresses spanner and screw hold-down bolt, universal ball end and locking bed gap are diminished gradually, hold-down bolt acts on disk spring by packing ring, disk spring generation elastic deformation, the disk spring after the deformation acts on latch segment, and latch segment is tightly pushed down universal joint, with its locking, make operating-table and parts thereof maintain static.Disk spring also remains a pre-pressing force in this process, and it is steady to guarantee that universal ball end is shifted one's position.
In aforementioned process, because pre-pressing force exists, make rigidity be packed together to the process that a flexibility compresses, make the operator more laborsaving, be convenient to operation.In the process that compresses, gets loose at gimbal suspension, stiff rigidity deformation can not take place again, effectively prolong the service life of each parts, reduce cost.
