Detailed Description
The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the utility model are shown, but in which the utility model is not so limited.
As shown in fig. 1, the unidirectional locking alignment device with triggering conditions comprises a base 1, a locking block 3, tension springs 4, a pressure spring 7, a bearing sliding block 8 and a shifting fork 9, wherein a window is formed in the base 1 in a hollow mode and is formed in the front and the rear of the base 1, the inner bottom of the base 1 is fixedly connected with one end of the pressure spring 7, the other end of the pressure spring 7 is fixedly connected with the bottom of the bearing sliding block 8, the bearing sliding block 8 slides in the base 1, an eccentric hole is formed in the portion, exposed out of the window of the base 1, of the bearing sliding block 8, a bearing pin 11 penetrates through the eccentric hole of the bearing sliding block 8 through clearance fit, two locking blocks 3 are respectively arranged at the front end and the rear end of the bearing pin 11 through clearance fit, a tension spring strut 5 is fixedly connected to the locking block 3 positioned in the front of the bearing sliding block 8, two tension spring struts 5 are respectively connected with two ends of the tension springs 4, two hinge pins 10 are respectively connected with two ends of the shifting fork 9, and hinge pins 10 are respectively connected with the two ends of the locking block 3 at the rear of the bearing sliding block 8.
The left and right sides of the bearing slide block 8 are provided with groove bodies, the left and right sides of the base 1 are respectively provided with a limiting pin 6 which is inserted into the groove bodies at the left and right sides of the bearing slide block 8, and the bearing slide block 8 is prevented from being ejected out of the base 1 by the pressure spring 7; the locking blocks 3 are fixedly connected with the bearing pin 11 through a positioning pin 2, so that synchronous rotation of the bearing pin 11 and the two locking blocks 3 is realized; the outer ends of the hinge pins 10 are provided with check rings for limiting the axial movement of the hinge pins 10.
Through the collocation of the parts, the device can realize the unidirectional locking function under the external input force.
The structural device is arranged in the framework of the basin bottom magnetic stimulation treatment chair and is positioned below the treatment magnetic beats, the use quantity of the therapeutic magnetic beats can be determined according to the specific structure of the basin bottom magnetic stimulation treatment chair, if 1 therapeutic magnetic beats are used, the therapeutic magnetic beats are placed in the middle of the basin bottom magnetic stimulation treatment chair, and if 2 therapeutic magnetic beats are used, the therapeutic magnetic beats are placed at two ends of the therapeutic magnetic beats, so that the therapeutic magnetic beats are symmetrically placed. In this embodiment, as shown in fig. 2, 2 pieces of the utility model are symmetrically placed under the therapeutic magnetic beats, the base 1 is mounted on the framework of the therapeutic chair by screws, and two bearing sliding blocks 8 are propped against the pre-adjusted therapeutic magnetic beats.
As shown in fig. 3, when the device of the present utility model is in the initial state, under the action of the tension spring 4, the hinge pin 10 fixedly connected to the locking block 3 is already propped against the open slot end of the fork 9, and the rotation of the locking block 3 is controlled by the rotation track of the fork 9.
As shown in fig. 4, when the device of the present utility model receives force, the received force is transferred to the bearing slide block 8 through the therapeutic magnetic claps, so that the bearing slide block 8 slides in the compression direction of the compression spring 7, the sliding of the bearing slide block 8 drives the bearing pin 11 and the two locking blocks 3 to slide downwards together, and simultaneously, the two locking blocks 3 and the bearing pin 11 rotate synchronously under the action of the shifting fork 9 and the hinge pin 10. Under the continuous or instant action of external input force, the bearing slide block 8 continuously slides downwards, simultaneously drives the bearing pin 11 and the two locking blocks 3 to continuously slide, and the two locking blocks 3 continuously rotate around the axis of the bearing pin 11 under the action of the shifting fork 9 until the bearing slide block reaches a certain position.
As shown in fig. 5, the carrier slider 8 reaches a bottoming position, which is a boundary condition reached by the carrier slider 8 from an initial state under the action of an external input force, where the mechanical characteristics and functions of the device of the present utility model will change. In this state, the locking block 3 rotates around the axis where the bearing pin 11 is located under the action of the shifting fork 9 to the dead point of the locking block, that is, the rotation moment generated by the tension force of the tension spring 4 on the locking block 3 reverses the direction at the moment, and as seen from the first diagram of fig. 5, before the locking block 3 reaches the dead point, the rotation moment generated by the tension force of the tension spring 4 on the locking block is anticlockwise, and the rotation moment after the dead point is reached becomes clockwise, wherein the shifting fork 9 has the function of enabling the locking block 3 to smoothly pass through the dead point and enabling the rotation moment to overturn.
As shown in fig. 6, in the state after the rotation moment is reversed, the locking block 3 rotates to a new position under the action of the tension spring 4, at this time, the opening end of the shifting fork 9 is not propped against the hinge pin 10 on the locking block 3, that is, the locking block 3 is separated from the motion constraint of the shifting fork 9, the locking block 3 rotates around the axis where the bearing pin 11 is located, one end of the locking block 3 always contacts with the window wall of the base 1 under the action of the tension spring 4, and in this state, the mechanical property of the device reaches the unidirectional locking function.
After external input force is removed, the device also smoothly passes through the dead point position of the locking block, at the moment, along with the rebound of the therapeutic magnetic bat, the bearing sliding block 8 synchronously rebounds under the action of the pressure spring 7, the locking block 3 on the moving direction does not play a locking role, and when the therapeutic magnetic bat rebounds to align with the therapeutic magnetic bat and the cushion wood board, the therapeutic magnetic bat is required to be locked at the position, and at the moment, the device can play a role in preventing the reverse direction movement.
As can be seen from fig. 7, when the load-bearing slider 8 rebounds under the action of the two compression springs 7, one end of the locking block 3 always contacts with the window wall of the base 1, the locking block 3 is acted by the contact force of the window wall of the base 1, wherein the contact force consists of friction force and positive pressure, and as can be seen from the first diagram of fig. 7, the contact force causes the locking block 3 to rotate anticlockwise around the axis where the load-bearing pin 11 is located, namely, the locking block 3 has a tendency to be separated from the contact of the window wall of the base 1, so that the load-bearing slider 8 is not blocked in the rebound direction; when the bearing slide block 8 rebounds to the level position of the therapeutic magnetic claps and the cushion wood board to stop, the bearing slide block 8 can not slide reversely any more, because at this time, if the trend of reverse movement exists or the force exceeding the compression direction of the pressure spring 7 is acted, the locking block 3 can be acted by the contact force of the window wall of the base 1, wherein the friction force direction in the contact force is towards the rebound direction of the pressure spring 7, so that the locking block 3 has the trend of rotating clockwise around the axis of the bearing pin 11, namely, the locking block 3 and the window wall of the base 1 are contacted more tightly, and the positive pressure causes the locking block 3 to have the trend of rotating anticlockwise around the axis of the bearing pin 11, so that the locking block 3 has the trend of separating from the window wall of the base 1, and when the contact friction coefficient of the window wall of the locking block 3 and the window wall of the base 1 and the related dimension meet the friction self-locking condition, the effect of the friction force can be larger than the effect, namely, the friction force of the two causes the locking block 3 and the window wall of the base 1 to contact more tightly, and the locking block 3 has the trend of wedging into the window wall of the base 1.
Through the structure and the installation position of the device, the triggering condition of the unidirectional locking function of the utility model becomes the therapeutic magnetic swatter itself of which the position is to be adjusted, the unidirectional locking function of the utility model can be realized through the external force applied to the cushion and the therapeutic magnetic swatter, and the self-adaptive alignment of the therapeutic magnetic swatter and the cushion can be realized under the condition that the adjustment cannot be touched or the invisible condition can not be realized.
Embodiment two: in another embodiment, the way that the locking block 3 is in contact with the window wall of the base 1 can be replaced by a ratchet and pawl locking way by friction self-locking, namely, the locking block 3 is deformed into a pawl structure, the window wall of the base 1 is deformed into a ratchet strip structure, and the way can also realize the function of unidirectional locking.
Embodiment III: in another embodiment, the form of the fork 9 controlling the rotation of the locking piece 3 may be replaced by a spring piston structure, and the resilience of the spring piston makes the locking piece 3 pass through the dead point smoothly when the locking piece 3 reaches the dead point position by using the compressibility and resilience of the spring piston.
The foregoing is only a preferred embodiment of the utility model, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the utility model.
