Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a stethoscope with adjustable squeezing force, which comprises: a stethoscope convenient for adjusting the degree of compression force comprises an ear piece 1, a thread mechanism and an elastic telescopic mechanism.

The earpieces 1 are arc-shaped, the earpieces 1 are arranged to be opposite to each other, the upper ends of the earpieces 1 are oppositely bent to form plug parts which are convenient to insert into ears, the lower ends of the earpieces 1 are connected through a connecting pipe 11 made of Y-shaped rubber, the earpieces 1 can rotate around the connecting pipe 11 to realize opening and closing, and the tail end of the connecting pipe 11 is connected with a chest piece 13 through a rubber pipe 12. The end of the plug part is provided with the earplug 3 made of rubber for the earplug, so that the toughness is increased, and the phenomenon that the ear is not easily extruded is avoided.

The screw thread mechanism is arranged between the two ear pieces 1, and the screw thread mechanism can push and pull the ear pieces 1 at two sides when rotating so as to open and close the two ear pieces 1 around the connecting pipe 11. The screw thread mechanism includes a screw thread section of thick bamboo 2, and threaded section of thick bamboo 2 interpolation has two screw threads 21 that the screw thread direction of turning is opposite about, and when screw thread section of thick bamboo 2 rotated, two screw threads 21 move in opposite directions or back-to-back, and the length of connecting pipe 11 is 15 ~ 20 mm. The connecting pipe 11 is made of rubber, is consistent with the rubber pipe 12 in material, has toughness, and has certain supporting force, the length of 15-20 mm is moderate, and the toughness and the supporting force are also right. The threaded cylinder 2 rotates, and the two threaded rods 21 approach to or depart from each other, so that the ear piece 1 is opened and closed to connect the position fulcrum of the pipe 11. The circumference of a screw thread section of thick bamboo 2 is provided with the anti-skidding burr of increase frictional force, increases frictional force, makes things convenient for the hand to hold between the fingers the rotation, and a screw thread section of thick bamboo 2 and threaded rod 21 here are the downside that is close to two ear pieces 1, are difficult to influence the chin, simultaneously, are close to connecting pipe 11 more, and the sensitivity of adjusting during the rotation is also higher more.

The elastic telescopic mechanism is arranged between the thread mechanism and the ear piece 1, the elastic telescopic mechanism can be elastically stretched when the two ear pieces 1 are pulled apart, and the tail end of the elastic telescopic mechanism can rotate around the ear piece 1. The elastic telescopic mechanism comprises coaxial guide cylinders 22 fixed at the opposite ends of the two threaded rods 21, the cross sections of the guide cylinders 22 are square, telescopic rods 23 matched with each other are inserted in the guide cylinders 22, the telescopic rods 23 can stretch along the guide cylinders 22, the outer ends of the telescopic rods 23 are rotatably connected with the ear pieces 1 on the same side, and the inner ends of the telescopic rods 23 and the inner ends of the inner cavities of the guide cylinders 22 are connected through elastic parts. The 22 cross-sections of guide cylinder are square, and guide cylinder 23 also rotates when avoiding a screw thread section of thick bamboo 2 to rotate, under elastomeric element's effect, taut two ear pieces 1 to realize that the cock portion presss from both sides tight ear, guarantee the effect, when a screw thread section of thick bamboo 2 drives two threaded rods 21 and is close to in opposite directions, the distance reduces between two ear pieces 1, and the centre gripping dynamics increases, and then just in time to some small in face, some big in face, then the reverse rotation screw thread section of thick bamboo 2. The elastic component is a spring 24, two ends of the spring 24 are fixedly connected with the corresponding end surfaces of the telescopic rod 23 and the guide cylinder 22 respectively, and the spring 24 has good elasticity and long service life.

Still include the installation mechanism of fixed mounting on the ear piece 1, installation mechanism can slide along ear piece 1 to the distance of adjustment screw thread section of thick bamboo 2 to the chin, and telescopic link 23 rotates with installation mechanism and is connected. If the threaded barrel 2 is close to next work, the threaded barrel 2 is moved downwards through the mounting mechanism, and meanwhile, the threaded barrel 2 is rotated to shrink the two threaded rods 21. The mounting mechanism comprises a coaxial sleeve 25 sleeved on the ear piece 1, the telescopic rod 23 is rotatably connected with the sleeve 25 through a pin shaft, a front lug and a rear lug for mounting the pin shaft are fixed on the sleeve 25, and a fastening component for fixing is arranged on the sleeve 25. The sleeve 25 can slide along the earpiece 1 and the fastening means are used to secure the sleeve 25. The fastening part is a fastening knob 26, the inner end of the fastening knob 26 abuts against the ear piece 1, and the fastening knob 26 is used for fixing, so that the ear piece is simple and convenient. The screw thread end of the fastening knob 26 is sleeved with a reinforcing screw thread cylinder 27 fixed on the sleeve 25, so that the connection length of the fastening knob 26 is increased, and the fastening knob is firmer and is not easy to slide.

The working principle is as follows: when the ear plug is used, the two ear pieces 1 are pulled outwards, the plug part can be plugged into the ear by overcoming the elasticity of the spring 24, and the flexibility of the ear plug 3 is increased, so that the ear is more comfortable; according to fat thin condition, when needing to adjust the distance between two ear pieces 1, rotate a screw thread section of thick bamboo 2, a screw thread section of thick bamboo 2 drives two threaded rods 21 and is close to each other or keeps away from, to the person that is fat on the face, make two threaded rods 21 outwards remove, increase the opening between two ear pieces 1, the clamping-force to the ear is just less like this, and is same, the person that is thin on the face, then opposite direction adjusts, threaded rod 21 removes in opposite directions, distance between two ear pieces 1 reduces, thereby better centre gripping ear, avoid too lax influence auscultation, spring 24 provides elastic tension, make telescopic link 23 remove in guide cylinder 22, press from both sides tight ear, here, can realize the elasticity adjustment through the rotation of rotating a screw thread section of thick bamboo 2, one-hand operation can, and is simple and convenient, and more practical, and convenient. For the person with thick chin, the fastening knob 26 can be unscrewed, the sleeve 25 can be moved downwards, and at the same time, the two threaded rods 21 can be moved inwards to ensure that the opening between the two ear pieces 1 is unchanged, so that the height of the threaded cylinder 2 is reduced, the distance from the chin is reduced, and the chin is prevented from being scratched.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
