Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to a connecting joint of a sphygmomanometer. Background Art
[0002] A sphygmomanometer is an instrument for measuring blood pressure, also known as a blood pressure meter. When measuring blood pressure, the sphygmomanometer needs to be inflated. The air pump inflates the cuff through a rubber hose, compressing the local artery with air pressure to stop the pulsation of the local artery, thereby measuring the blood flow pressure during this period.
[0003] The existing hoses of sphygmomanometers are mostly of two-section structure, one section is connected to the sphygmomanometer, and the other section is connected to the cuff. The two sections of the hose are connected by a male and female connector. However, the female connector in the existing connector is recessed in the hose. During connection, it is impossible to confirm whether the male and female connectors are aligned. The position needs to be repeatedly adjusted to align with the hole before insertion and connection, which is very inconvenient. Utility Model Content

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1-Figure 8 As shown, a connecting joint of a sphygmomanometer described in the utility model comprises a male head 1 and a female head 2; the male head comprises a first rubber hose 11, a first connecting seat 12 fixedly mounted on the first rubber hose, a first conical seat 13 fixedly mounted on the first connecting seat, a first connecting head 14 fixedly mounted on the first conical seat, an elastic mechanism 15 slidably mounted on the first connecting head, and a limiting mechanism 16 slidably mounted on the first conical seat; the female head comprises a second rubber hose 21, a second connecting seat 22 fixedly mounted on the second rubber hose, a second conical seat 23 fixedly mounted on the second connecting seat, and a second magnet 24 fixedly mounted on the second conical seat.
[0027] Specifically, the male head and the female head further include a self-locking mechanism 3 .
[0028] Specifically, the male connector and the female connector further include a sealing mechanism 4 .
[0029] Specifically, the elastic mechanism includes a first slide groove 151 fixed on the first connector, a bottom plate 152 slidably disposed on the first slide groove, and a first magnet 153 fixed on the bottom plate; the bottom plate and the first conical seat are connected via a spring 154.
[0030] Specifically, the limiting mechanism includes a limiting sleeve 161 slidably mounted on the first conical seat and a limiting groove 162 fixedly mounted on the limiting sleeve.
[0031] Specifically, the self-locking mechanism includes a second slide groove 31 fixed on the first connecting seat, a locking groove 32 fixed on the first connecting seat, a third slide groove 33 fixed on the second connecting seat, a self-locking sleeve 34 slidably arranged on the third slide groove, and a locking block 35 fixed on the self-locking sleeve.
[0032] Specifically, the sealing mechanism includes a sealing sleeve 41 fixedly arranged on the first connecting seat, a first sealing ring 42 fixedly arranged on the first connecting seat, and a second sealing ring 43 fixedly arranged on the second connecting seat.
[0033] When in use, align the first connector with the second conical seat, insert the first connector into the second conical seat, the first magnet and the second magnet are attracted and fit together, then continue to push the second connector, the second magnet pushes the first magnet and the bottom plate to move on the first slide slot, and the spring is compressed. After pushing a certain distance, the second conical seat contacts the inclined surface of the limiting sleeve, and the second conical seat pushes the limiting sleeve to move along the second conical seat. During the movement, the two ends of the limiting sleeve will be squeezed and expanded by the first conical seat and the second conical seat. After the limiting sleeve expands, it squeezes and fits the sealing sleeve, and the sealing sleeve also applies a reaction force to the limiting sleeve, so that the limiting sleeve clamps the second conical seat, making the connection more stable.
[0034] by Figure 2 For example, in the process of pushing the second connecting seat, the locking block will enter the second sliding groove. When the first sealing ring and the second sealing ring are in contact, the self-locking sleeve will be pushed downward, and the self-locking sleeve will slide to the bottom of the third sliding groove. Since the third sliding groove is slightly shorter than the second sliding groove, the locking block has not moved to the bottom of the second sliding groove at this time. Continue to push the self-locking sleeve downward, and the self-locking sleeve will drive the second connecting seat to move downward. The first sealing ring and the second sealing ring will be over-extruded at this time. When the locking block moves to the bottom of the second sliding groove, the self-locking sleeve is rotated, and the locking block will rotate to the bottom of the locking groove. At this time, the self-locking sleeve is released, and the spring will push the bottom plate to move upward, and then push the second connecting seat to move upward. Since the self-locking sleeve is located at the bottom of the third sliding groove at this time, when the second connecting seat moves upward, it will drive the self-locking sleeve to move upward together, and then the locking block moves to the top of the locking groove to complete self-locking. The first sealing ring and the second sealing ring are in a normal fitting state at this time.
[0035] During disassembly, push the self-locking sleeve downward, the self-locking sleeve will drive the second connecting seat to move downward, the first sealing ring and the second sealing ring will be over-squeezed at this time, and when the locking block moves to the bottom of the locking groove, rotate the self-locking sleeve in the opposite direction, the locking block will rotate to the bottom of the second slide groove, at this time release the self-locking sleeve, the spring will push the bottom plate to move upward, and then push the second connecting seat to move upward. Since the other end of the self-locking sleeve is located at the bottom of the third slide groove, when the second connecting seat moves upward, it will drive the self-locking sleeve to move upward together, and then the locking block moves upward along the second slide groove, releasing the self-locking, the first sealing ring and the second sealing ring are disengaged, and then pull the second connecting seat upward to separate the first magnet and the second magnet, and complete the disassembly.
