Example 1:

referring to fig. 1, an embodiment of the present invention, the adjustable popliteal pad comprises a supporting unit 100 and an adjusting unit 200.

Specifically, the receiving unit 100 has a triangular prism structure, and the triangular prism is designed to have a through hole hollow structure in consideration of the lightweight type of the device, and the three sides of the triangular prism structure may be divided into a rocker plate 101, a bushing structure 102, and a base plate 103. The rocking plate 101 and the bushing structure 102 are connected through a rotating shaft (a hinge connection can also be used), so that the rocking plate 101 can rotate around the rotating shaft; the inlaid structure 102 and the bottom plate 103 are vertically fixed together through mechanical connection; the rocker plate is connected with the base plate 103 in an open manner, and in this embodiment, the rocker plate is not connected with the base plate, and a snap connection can be used.

The inlaid structure 102 is a hollow plate capable of being inlaid and formed by rolling a metal strip or a plastic sheet, and the metal strip or the plastic sheet is pre-shaped into an elastic curled layer with a memory function and smaller than the outer diameter of the plate body, so that the inlaid structure has a self-tightening function, and the curled layer always has elastic potential energy for applying pressure to the telescopic hollow plate. The outer diameter difference of each section of plate is not more than 0.2mm, one end of each section of plate is curled inwards, the other end of each section of plate is curled outwards, and then the plates are sequentially sleeved and connected. (telescoping rod principle, like the telescopic plate rod structure of a luggage case).

The mounting structure 102 is a structure that helps the carrying unit 100 to be able to zoom in and out in vertical height, and in practical application, a common flat plate structure can be used.

The adjusting unit 200 includes a first adjusting member 201.

The first adjustment assembly 201 is configured as a torsion shaft. The working principle of the torsion rotating shaft is that the torsion applied by the outside is smaller than the torsion required by the rotation of the rotating shaft, and if the applied torsion is continuously increased by the outside, the torsion is larger than the torsion required by the rotation of the rotating shaft, and then the rotating shaft can rotate. The axis of the torsion rotating shaft is on the same straight line with the axis of the rotating shaft arranged between the rocking plate 101 and the bushing structure 102, and in the limit, the first adjusting component 201 adopts the torsion rotating shaft which is completely used as the connecting part of the rocking plate 101 and the bushing structure 102. Which intermittently holds the rocker paddle 101 stationary at an angle to the mounting structure 102.

When using the adjustable popliteal pad of this embodiment, the user places his legs on the support unit 100, and the popliteal pad is placed on the rotation axis between the rocker plate 101 and the inlay structure 102. Then, according to actual conditions, the extension length of the inlay structure 102 is adjusted to adjust the height of the popliteal pad, and the first adjusting assembly 201 is rotated to rotate the torsion rotating shaft to adjust the angle of the popliteal pad.

Example 2:

referring to fig. 1-2, an embodiment of the present invention is an adjustable popliteal pad, which is different from embodiment 1 in that: the adjustment unit 200 further comprises a second adjustment assembly 202, the second adjustment assembly 202 being arranged on the mounting structure 102 of the receiving unit 100.

Specifically, the inlay structure 102 is divided into two parts, an inlay 102a and a case 102b, the inlay 102a being insertable into the case 102 b; the second adjustment assembly 202 includes a limited number of pin holes 202a and pins 202b disposed on the mounting structure 102; the pin 202b can be inserted into the pin hole 202a to fix the relative positions of the inlay 102a and the shell 102b in the inlay structure 102.

In consideration of the structural portability, the inlay 102a is designed to be a grid-shaped flat plate structure, and is shaped like a flat plate net frame, which is called a net frame for short; the grid structure has the advantages of large space rigidity, good integrity and stability, good earthquake resistance and good modeling effect, and is convenient to manufacture.

In practice, the addition of the second adjustment assembly 202 increases the stability of the carrying unit 100 to maintain a certain height, so that the inlay 102a and the sleeve 102b do not slide relative to each other when the patient is using the carrying unit.

When using the adjustable popliteal pad of this embodiment, the user places his legs on the support unit 100, and the popliteal pad is placed on the rotation axis between the rocker plate 101 and the inlay structure 102. The pins 202b of the second adjustment assembly 202 can then be pulled out of the pin holes 202a of the inlay 102, and the extended length of the inlay 102 can then be adjusted to achieve the adjustment of the height of the popliteal pad, and the rotation of the torsion shaft of the first adjustment assembly 201 can be rotated to achieve the adjustment of the angle of the popliteal pad, as the case may be.

Example 3

The axial cross-section of the pin hole 202a and the pin 202b of the second adjustment assembly 202 is quadrilateral, and the end surface of the pin 202b is a slope surface.

Specifically, a blind hole a is formed in the casing 102b, a spring is placed in the blind hole a, the spring is fixed at the bottom of the blind hole a, and the other end of the spring is fixedly connected with a pin 202 b.

The axial cross-section of the pin 202b and the pin hole 202a is quadrilateral, and the contact mode is surface contact, so that the stability is higher. The end face of the pin 202b is provided with a slope half-slope, and the slope can realize unidirectional locking when external force is applied to the hand-held inlay 102a in a direction perpendicular to the axis of the pin 202 b. The inlay 102a is movable in one direction and not movable in the other direction.

When using the adjustable popliteal pad of this embodiment, the user places his legs on the support unit 100, and the popliteal pad is placed on the rotation axis between the rocker plate 101 and the inlay structure 102. Then, the pin 202b of the second adjusting member 202 is pulled out from the pin hole 202a of the bushing structure 102 (the spring is in a stretching state at this time) according to actual conditions, and then the extending length of the bushing structure 102 is adjusted to adjust the height of the popliteal pad, (after the adjustment is completed, since the pin 202b is fixed on the bushing structure 102 through the spring, the spring automatically pulls the pin 202b back to the pin hole 202a aligned at this time after the hand is loosened), and the rotation of the torsion rotating shaft of the first adjusting member 201 is rotated to adjust the angle of the popliteal pad.

If the popliteal pad is intended to be taller, the inlay 102a may also be pulled in a single direction, such that the pin 202b may be pushed away from the pin hole 202a due to the ramped surface of the pin 202b, such that the inlay 102a may be pulled.

Specifically, in consideration of the portability of the device, the inlay 102a of the inlay structure 102 is a hollow plate structure, one end of the inlay is set as an arc b, and brackets are arranged at two sides of the inlay structure for receiving the rocker plate 101 and connecting the rotating shaft with the inlay structure 102; one end of the inlay structure 102 is provided with a round shaft type structure c which can be wrapped in the arc b of the inlay 102a, and the rocker plate 101 and the inlay structure 102 are connected with a rotating shaft and arranged on the round shaft structure c; the first adjusting component 201 is designed to be a ratchet structure, a ratchet 201a of the ratchet structure is welded on one end of the rotating shaft, and when the ratchet 201a rotates, the rotating shaft is driven to rotate; the pawl 201b is arranged on a circular shaft structure c of the rocking plate 101; a spring diaphragm 201c is provided below the pawl 201 b.

The ratchet mechanism can convert continuous rotation or reciprocating motion into unidirectional stepping motion, and belongs to the mature prior art scheme. Generally, the ratchet mechanism is provided with a rocker on which the pawl is provided, and in the present embodiment, the rocker plate 101 replaces the rocker of the conventional ratchet mechanism.

In this embodiment, the ratchet 201a and the pawl 201b form a unidirectional intermittent motion mechanism, the teeth of the ratchet 201a are unidirectional teeth, the pawl 201b is hinged on the rocking plate 101, and when the rocking plate 101 swings clockwise, the driving pawl 201b is inserted into the teeth of the ratchet to push the ratchet 201a to rotate in the same direction; when the rocker plate 101 swings counterclockwise, the pawl 201b slides over the ratchet wheel 201a, and the ratchet wheel 201a stops rotating. The diaphragm spring 201c is used for ensuring that the pawl 201b can be attached to the ratchet 201a, and when the ratchet mechanism needs to be reset, the diaphragm spring can be moved, so that the pawl 201a is separated from the ratchet 201a, and at this time, the ratchet 201a can rotate in both the clockwise direction and the anticlockwise direction.
