Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially, relates to a kind of support arm structure of baking lamp. BACKGROUND

[0002] There are many medical instruments in hospital, and the medical instruments are used to assist the treatment of patients' diseases. The height and angle of the medical instruments need to be adjusted during use, so the height and angle adjustment performance of the medical instruments has certain requirements. For example, baking lamp therapeutic instrument, which emits heat to act on the treatment site through clothes, and then through the skin, directly makes muscle, subcutaneous tissue and other tissues produce heat effect, accelerates blood circulation, increases metabolism, reduces pain, increases muscle relaxation, produces massage effect, etc. Due to its special treatment effect, it is widely used in various departments of hospitals.

[0003] The height and angle of the existing baking lamp therapeutic instrument are mainly adjusted by its support. The support includes two groups of quadrilateral support arms, each group of support arms includes two parallel support rods and a tension spring, the two support rods of the upper support arm are hinged between the upper connecting seat and the middle connecting seat, the tension spring of the upper support arm is hinged between the middle connecting seat and one of the support rods of the upper support arm, the two support rods of the lower support arm are hinged between the middle connecting seat and the lower connecting seat, and the tension spring of the lower support arm is hinged between the middle connecting seat and one of the support rods of the lower support arm. The lines connecting the two ends of the two support rods in each group of support arms always remain a parallelogram, the upper connecting seat is connected with a therapeutic lamp, and the lower connecting seat is connected with a base or a height adjustment support. During use, the upper and lower support arms are swung to separate the two support rods in the same group of support arms, the distance between the therapeutic lamp and the middle connecting seat and the lower connecting seat is adjusted, and the height and angle of the therapeutic lamp are adjusted. When the upper support arm is swung, the swinging of the upper support arm stretches the tension spring of the upper support arm, and the upward component force of the tension spring of the upper support arm balances the gravity of the upper support arm. Similarly, when the lower support arm is swung, the swinging of the lower support arm stretches the tension spring of the lower support arm, and the upward component force of the tension spring of the lower support arm balances the gravity of the lower support arm, thereby maintaining the angle and height of the therapeutic lamp adjusted.
