DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] like Figures 1 to 12 As shown, the limiting clamp of the medical harness of the present invention comprises a base 1, a locking member 2, a pressure member 3 and a locking block 4. The locking member 2 is arranged on the base 1 and can move up and down on the base 1, thereby driving the pressure member 3 installed on the locking member 2 to move up and down. The locking block 4 is arranged in the middle of the base 1 and is used to limit the position of the locking member 2, so that after the pressure member 3 on the locking member 2 limits the position of the medical harness, the locking member 2 will not be pushed in the reverse direction.

[0037] The base 1 is provided with a notch 5 for accommodating the medical harness, and the notch 5 is used to place the medical harness and limit the position of the medical harness. At the same time, the pressure of the pressure member 3 on the locking member 2 is cooperated so that the medical harness in the notch 5 is compressed.

[0038] Cover plates 6 are provided on both sides of the base 1 , locking arms 7 are provided on the cover plates 6 , undercut portions 8 are provided on the locking arms 7 , and locking grooves 9 matched with the undercut portions 8 are provided on the base 1 .

[0039] The lower end of the receiving hole 10 is connected to the receiving groove 11. A connecting hole 12 is provided inside the base 1.

The limiting groove 16 cooperates with the locking block 4. A positioning surface 18 cooperating with the limiting surface 15 is provided on the locking end 17.

[0040] The locking member 2 is symmetrically arranged on the base 1, and the base 1 is provided with a receiving hole 10 for receiving the locking member 2. The locking member 2 is composed of a pressing body 19, a connecting body 20 and a locking body 21. An installation area 22 is formed between the pressing body 19 and the locking body 21, the connecting body 20 is placed in the installation area 22, and the pressure member 3 is arranged in the installation area 22.

[0041] The cross section of the connecting body 20 is circular, and the pressure member 3 is provided with a receiving opening 23 for receiving the connecting body 20 . The receiving opening 23 is provided with an entry opening 24 . The receiving opening 23 is arranged in an arc shape, and the arc angle is a major arc.

[0042] A plurality of first teeth 25 are provided on the locking body 21. The locking block 4 is composed of a rotating end 26 and a locking end 17, and the locking end 17 is provided with a second tooth 27 that matches with the first teeth 25.

[0043] A tooth groove 28 is formed between the first teeth 25, and the second teeth 27 is disposed in the tooth groove 28.

The first plane 30 and the second plane 32 are in contact, and the first inclined surface 29 and the second inclined surface 31 cooperate to guide.

[0044] With the cooperation of the limiting surface 15 and the positioning surface 18 , the locking block 4 cannot rotate upwards and can only be pushed and rotated downwards by the locking member 2 , thereby compressing the second elastic member 33 .

[0045] A cavity 34 is formed in the middle of the rotating end 26, and a surface of the cavity 34 close to the first through hole 35 is a contact surface 36, which cooperates with a blocking surface 38 of the blocking head 37. The locking block 4 is pushed by the first elastic member 13, so that the contact surface 36 contacts the blocking surface 38. The cover plate 6 is provided with a rotating hole 39 for accommodating the rotating end 26.

[0046] A first through hole 35 is provided at one end of the locking block 4, and a second through hole 40 is provided at the other end.

[0047] The pressure member 3 is arranged on the symmetrical locking member 2, and the pressure member 3 is arranged at the upper end of the notch 5. The pressure member 3 is composed of a pressure strip 41 and a pressure block 42. The pressure strip 41 and the pressure block 42 are connected by a connecting portion 43, and the pressure block 42 is arranged in a triangular shape. During installation, the pressure member 3 is directly inserted into the connector 20 to limit the position, so that the pressure member 3 is installed on the locking member 2.

[0048] The locking block 4 is arranged inside the base 1, and a receiving groove 11 for receiving the locking block 4 is arranged in the middle of the base 1. The locking block 4 cooperates with the locking member 2 to limit the position of the locking member 2 in the receiving hole 10. The locking blocks 4 are arranged symmetrically, and a first elastic member 13 is arranged between the symmetrically arranged locking blocks 4. When the first elastic member 13 is between the locking blocks 4, it remains in a compressed state, so that the first elastic member 13 has a certain elastic potential energy, pushing the locking blocks 4 at both ends, so that the contact surface 36 contacts the blocking surface 38.

[0049] A second elastic member 33 is provided at the lower end of the locking block 4, one end of the second elastic member 33 is connected to the locking block 4, and the other end is connected to the inner wall of the receiving groove 11.

The second elastic member 33 is a tension spring, the first elastic member 13 is a spring, one end of the second elastic member 33 is connected to the first fixing ring 44, and the other end is connected to the second fixing ring 45.

[0050] And from the attached Figure 3 It can be seen that the second fixing ring 45 is not located directly below the first fixing ring 44, but is offset toward the inside of the receiving groove 11, which can better limit the position of the locking block 4. The state of the second elastic member 33 remains in a natural state. When the locking block 4 is pressed, the locking block 4 can stretch the second elastic member 33, so that the locking end 17 of the locking block 4 enters the limiting groove 16.

[0051] The locking blocks 4 are connected to each other through a rotating shaft 14, and the first elastic member 13 is installed on the rotating shaft 14. A plurality of strip grooves 46 are provided at both ends of the rotating shaft 14, and an elastic arm 47 is provided at one end of the strip groove 46, and a blocking head 37 is provided on the elastic arm 47, and a blocking surface 38 and a first guiding inclined surface 48 are provided on the blocking head 37.

[0052] The locking end 17 is provided with a second guiding inclined surface 49 that matches with the first guiding inclined surface 48 . The second guiding inclined surface 49 is disposed at one end of the first through hole 35 .

[0053] Press the pressure piece 3, keep the pressure piece 3 to drive the locking piece 2 to move downward, apply pressure to the medical wiring harness in the notch 5, and when in contact, press the locking block 4 to keep the first elastic piece 13 compressed and the second elastic piece 33 stretched, keeping the locking block 4 separated from the locking piece 2.

[0054] In addition, a fixing groove 50 is provided at the lower end of the base 1, and a magnet 51 is provided in the fixing groove 50, so as to facilitate the absorption of the limit clip on a magnetic object, thereby guiding and limiting the medical wire harness.

[0055] When in use, first remove the pressure piece 3 or directly pass the medical wire harness between the pressure piece 3 and the base 1, and then directly press the pressure piece 3 so that the pressure body applies pressure to limit the medical wire harness in the notch 5.

[0056] When the medical wire harness in the gap 5 needs to be taken out, the rotating ends 26 at the cover plates 6 at both ends are pressed, so that the locking block 4 compresses the first elastic member 13, so that the second teeth 27 on the locking block 4 enter the limiting groove 16 and separate from the first teeth 25, and then the pressure member 3 can be pulled. Alternatively, the pressure member 3 can be directly removed.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
