Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an electric lifting frame for a physiotherapy lamp that can rotate 360 ​​degrees. Background Technology

[0002] A physiotherapy lamp lifting frame is a device used to support and adjust the position of physiotherapy lamps (such as infrared physiotherapy lamps, phototherapy lamps, etc.). During physiotherapy treatment, the height and irradiation angle of the physiotherapy lamp need to be flexibly adjusted according to the patient's body position and height. Therefore, physiotherapy lamp lifting frames usually integrate electric lifting and 360-degree rotation functions. The rotating joints of existing physiotherapy lamp lifting frames mostly adopt a fixed damping structure, while the electric lifting part achieves height adjustment through the cooperation of a telescopic rod and motor transmission.

[0003] Because the existing damping force is a fixed design, it cannot adapt to the differences in the weight of the physiotherapy lamp and the differences in usage habits. When the physiotherapy lamp is heavy, the fixed damping is "insufficient force", resulting in wobbling after rotation and poor angle positioning accuracy; when the physiotherapy lamp is light, the fixed damping is "excessive force", resulting in jamming during rotation and difficulty in operation.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing an electric lifting frame for a physiotherapy lamp that can rotate 360 ​​degrees. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a 360-degree rotatable electric lifting frame for physiotherapy lamps. Firstly, the damping force of this utility model is flexibly adjustable. By rotating the adjustment knob, the pressure of the spring on the friction plate can be changed, adapting to physiotherapy lamps of different weights and different usage habits (such as quick adjustment or precise positioning). This solves the problem of "shaking when too heavy and jamming when too light" caused by fixed damping in existing technologies, improving angle positioning accuracy. Secondly, the sealing cover of this utility model, through a threaded ring and connecting pipe sealing cooperation, can effectively isolate dust and impurities from corroding the damping components. Combined with the wear-resistant properties of the composite resin friction plate, it reduces wear on the damping components, avoids "locking up" or "loss of control" phenomena, and extends the service life of the rotating joint.

[0006] This utility model provides the following technical solution: an electric lifting frame for a physiotherapy lamp that can rotate 360 ​​degrees, including an electric lifting frame body;

[0007] The top of the electric lifting frame body is connected to a connecting pipe by bolts. A connecting rod is rotatably connected to the inner cavity of the connecting pipe. A screw is coaxially fixed to one end of the connecting rod. Multiple friction plates are fitted on the surface of the screw. An adjusting knob is threadedly connected to the surface of the screw. A compression spring is provided between the adjusting knob and the friction plates. A sealing cover is fitted on the surface of the adjusting knob. The sealing cover is detachably connected to the connecting pipe through the threaded ring.

[0008] As a preferred embodiment of this utility model, the connecting tube is internally threaded with a fixing knob a, and the surface of the connecting rod is provided with a plurality of locking holes a in an annular array, with one end of the fixing knob a extending into the inner cavity of the locking hole a.

[0009] As a preferred technical solution of this utility model, the surface of the connecting rod is provided with a plurality of locking holes b in a ring-shaped array at intervals, and at least one connecting frame is movably sleeved on the surface of the connecting rod. Each connecting frame is internally threaded with a fixing knob b, and one end of the fixing knob b extends into the inner cavity of the locking hole b.

[0010] As a preferred embodiment of this utility model, each of the connecting frames is provided with a symmetrical sliding groove on its top, and a connecting bolt passes through the inner cavity of the sliding groove.

[0011] As a preferred embodiment of this utility model, the surface of the adjustment knob is provided with anti-slip texture, and the compression spring is a disc spring, one end of which abuts against the friction plate and the other end of which abuts against the adjustment knob.

[0012] As a preferred technical solution of this utility model, the bottom of the electric lifting frame body is provided with a support frame, and the electric lifting frame body is detachably connected to the inner cavity of the support frame by bolts.

[0013] As a preferred embodiment of this utility model, the top of the support frame is connected to a connecting plate by screws, and the top of the connecting plate is fixed with a control panel for controlling electric lifting by screws.

[0014] As a preferred embodiment of this utility model, the bottom of the support frame is fixedly connected with multiple self-locking casters, and the friction pad is a composite resin friction pad.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 As shown, a physiotherapy lamp electric lifting frame that can rotate 360 ​​degrees includes an electric lifting frame body 1;

[0027] The top of the electric lifting frame body 1 is connected to a connecting pipe 2 by bolts. A connecting rod 201 is rotatably connected to the inner cavity of the connecting pipe 2. A screw 202 is coaxially fixed to one end of the connecting rod 201. Multiple friction plates 203 are fitted on the surface of the screw 202. An adjusting knob 204 is threadedly connected to the surface of the screw 202. A compression spring 205 is provided between the adjusting knob 204 and the friction plates 203. A sealing cover 206 is fitted on the surface of the adjusting knob 204. The sealing cover 206 is detachably connected to the connecting pipe 2 by a threaded ring 207.

[0028] The connecting tube 2 has a fixed knob a3 connected to its internal thread. The surface of the connecting rod 201 has multiple locking holes a301 arranged in a ring array. One end of the fixed knob a3 extends into the inner cavity of the locking hole a301.

[0029] The surface of the connecting rod 201 is provided with a plurality of locking holes b4 in a ring-shaped array at intervals. At least one connecting bracket 401 is movably sleeved on the surface of the connecting rod 201. Each connecting bracket 401 is internally threaded with a fixing knob b402, one end of which extends into the inner cavity of the locking hole b4.

[0030] Each connecting bracket 401 has a symmetrical sliding groove 5 on its top, and a connecting bolt 501 passes through the inner cavity of the sliding groove 5.

[0031] The surface of the adjustment knob 204 is provided with anti-slip texture. The compression spring 205 is a disc spring, one end of which abuts against the friction plate 203 and the other end of which abuts against the adjustment knob 204.

[0032] The electric lifting frame body 1 is provided with a support frame 6 at its bottom. The electric lifting frame body 1 is detachably connected to the inner cavity of the support frame 6 by bolts.

[0033] The top of the support frame 6 is connected to a connecting plate 7 by screws, and the top of the connecting plate 7 is fixed with a control panel 701 for controlling electric lifting by screws.

[0034] The bottom of the support frame 6 is fixedly connected with multiple self-locking casters 8, and the friction plate 203 is a composite resin friction plate.

[0035] The electric lifting frame body 1 provides a lifting support base, and its top is fixed to the connecting pipe 2 by bolts. The connecting rod 201 is rotatably connected to the inner cavity of the connecting pipe 2, which can achieve 360-degree rotation.

[0036] A friction plate 203 is fitted on a screw 202 at one end of the connecting rod 201. An adjusting knob 204 is threadedly engaged with the screw 202. When the adjusting knob 204 is rotated, the pressure on the friction plate 203 can be changed by the compression spring 205 (disc spring), thereby adjusting the damping force when the connecting rod 201 rotates.

[0037] The sealing cap 206 is connected to the connecting pipe 2 via the threaded ring 207, forming a sealed protection for the damping adjustment structure.

[0038] When a fixed rotation angle is required, tighten the fixing knob a3 on the connecting tube 2 so that one end of it extends into the locking hole a301 on the surface of the connecting rod 201 to lock it.

[0039] The connecting frame 401 is movably sleeved on the connecting rod 201. By tightening the fixing knob b402, it extends into the locking hole b4, which can fix the position of the connecting frame 401. The physiotherapy lamp is installed by the connecting bolt 501 passing through the sliding groove 5 on the top of the connecting frame 401. The sliding groove 5 can finely adjust the installation position.

[0040] The bottom of the electric lifting frame body 1 is detachably connected to the support frame 6. The self-locking casters 8 at the bottom of the support frame 6 enable the overall movement and fixation. A control panel 701 is fixed on the connecting plate 7 at the top of the support frame 6 to control the lifting action of the electric lifting frame body 1.

[0041] The electric lifting frame body 1 adopts a three-section nested structure of outer rod, middle rod, and inner rod, which is based on existing technology. Adjacent rods are slidably fitted by a spline structure (the mating surfaces of the outer rod and middle rod, and the middle rod and inner rod are provided with spline teeth), which constrains each rod to move only along the axial direction and not rotate circumferentially. A drive motor is fixed at the bottom of the inner cavity of the outer rod, and the output shaft of the motor is connected to the first lead screw. The first lead screw is threadedly engaged with the first transmission nut fixed to the bottom of the middle rod. A second lead screw is fixed at the top of the inner cavity of the middle rod. The second lead screw is threadedly engaged with the second transmission nut fixed to the bottom of the inner rod, and the top of the inner rod is bolted to the connecting pipe.

[0042] When the lifting command is triggered via control panel 701: the drive motor rotates forward, causing the first lead screw to rotate, and the first transmission nut rises axially along the first lead screw, pushing the middle rod to extend upward along the inner cavity of the outer rod; simultaneously, during the upward movement of the middle rod, the second lead screw in its inner cavity moves synchronously with the middle rod, and the second transmission nut rises axially along the second lead screw, causing the inner rod to extend further upward along the inner cavity of the middle rod, achieving a three-stage linkage lifting of the outer rod, middle rod, and inner rod; when the motor reverses, each rod retracts sequentially, completing the height adjustment. The spline structure ensures no radial sway during the lifting of the three rods, ensuring the stability of the top-connected physiotherapy lamp during height adjustment.
