DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1-5 As shown;

[0025] A snap-on fixed spiral cable comprises a connector 1, wherein both ends of the connector 1 are respectively covered with a connector sleeve 1 2 and a connector sleeve 2 3, and the outer sides of the connector sleeve 1 2 and the connector sleeve 2 3 are connected to the cable body 4; a locking mechanism 9 is provided in the connector 1, wherein a mounting seat 13 is symmetrically provided in the connector 1, and a movable groove 2 131 is evenly provided on the mounting seat 13, and the locking mechanism 9 is installed in the movable groove 2 131, and the locking mechanism 9 comprises a fixing rod 91, which is fixed in the movable groove 2 131, and a frustum 1 92 is fixed at one end of the fixing rod 91, and a frustum 2 93 is covered on the outer periphery of the fixing rod 91, and the frustum 2 93 and the frustum 1 92 are symmetrical, and positioning rods 94 are evenly provided on the inner sides of the connecting sleeves 1 2 and 2 3. The positioning rod 94 is sleeved with an elastic member 2 96, which can be a spring. A clamping block 95 is fixed to the other end of the elastic member 2 96. The clamping block 95 extends out of the positioning rod 94. The clamping block 95 is wedge-shaped and matches the frustum 2 93 and the frustum 1 92. A telescopic groove 132 is provided in the mounting seat 13 corresponding to the inner side of the movable groove 2 131. An elastic member 3 98 is installed in the telescopic groove 132. The elastic member 3 98 can be a spring. A rebound rod 97 is fixed to the other end of the elastic member 3 98. The rebound rod 97 corresponds to the position of the positioning rod 94.

[0026] During installation, the connecting sleeve 1 2 and the connecting sleeve 2 3 are respectively put on the two ends of the connecting head 1, so that the positioning rod 94 is inserted into the movable groove 2 131, and then the connecting sleeve 1 2 and the connecting sleeve 2 3 are pushed inward to move the positioning rod 94 into the movable groove 2 131, so that the clamping block 95 slowly contacts the frustum 1 92. When the clamping block 95 contacts the frustum 1 92, since the inclined surface of the clamping block 95 and the inclined surface of the frustum 1 92 are in the same direction, the clamping block 95 is squeezed by the frustum 1 92 and retracted into the positioning rod 94. At the same time, the elastic member 2 96 is compressed. When the block 95 moves to the inside of the cone 1 92, the block 95 is separated from the cone 1 92, and the block 95 extends out. In the process of the positioning rod 94 moving inward, the elastic member 3 98 is squeezed by the rebound rod 97. At this time, the connecting sleeve 1 2 and the connecting sleeve 2 3 are loosened, so that the rebound rod 97 rebounds and abuts against the end of the positioning rod 94, so that the block 95 abuts against the inside of the cone 1 92. In this way, the cone 1 92 will restrict the block 95, so that the connecting sleeve 1 2 and the connecting sleeve 2 3 are fixed, and the installation is completed. When disassembling, continue to push the connecting sleeve inward. The first sleeve 2 and the second sleeve 3 are connected to make the block 95 continue to move inward. Since the inclined surface of the block 95 is opposite to the inclined surface of the second cone 93, when the block 95 contacts the second cone 93, it is squeezed into the positioning rod 94 by the second cone 93. In the process of continuing to move, the block 95 will slowly extend from the positioning rod 94 until the block 95 moves to the inner side of the second cone 93. Since the second cone 93 is movable on the fixed rod 91, the block 95 is against the inner side of the second cone 93. Then the connecting sleeve 1 2 and the connecting sleeve 2 3 are released. The elastic member 3 98 drives the rebound rod 97 to rebound, so that the clamping block 95 drives the frustum 2 93 to move outward until the frustum 2 93 and the frustum 1 92 are in contact. At this time, the positioning rod 94 is still pushed outward by the rebound rod 97, and the clamping block 95 will slowly retract into the positioning rod 94. Since the frustum 2 93 and the frustum 1 92 are in contact, the clamping block 95 moves directly to the outside of the frustum 1 92, so that the clamping block 95 contacts the restriction. In this way, the connecting sleeve 1 2 and the connecting sleeve 2 3 can be removed. This disassembly method is convenient and fast, and improves maintenance efficiency.

[0027] Furthermore, a connecting core 5 is provided on the inner side of the connecting sleeve 1 2 and the connecting sleeve 2 3, and the two connecting cores 5 are connected to each other. A component for connecting the two is provided in the connecting head 1 (not shown in the figure). This connecting component is cylindrical and realizes connection without affecting the inward movement of the connecting core 5. A card seat 51 is provided on the periphery of the connecting core 5. A snap mechanism 6 is evenly provided in the connecting head 1. The snap mechanism 6 includes a connecting plate 61. A movable groove 12 is evenly provided in the connecting head 1. The connecting plate 61 is fixed in the movable groove 12 by an elastic member 64. The elastic member 64 can be a spring. A card plate 62 is provided perpendicular to the end of the other side of the connecting plate 61. The card plate 62 extends into the connecting head 1 and matches the card seat 51. The outward contact surface of the card plate 62 is wedge-shaped, and the inward contact surface of the card seat 51 is wedge-shaped.

[0028] During installation, push the connecting sleeve 1 2 and the connecting sleeve 2 3 inward, and the connecting core 5 moves in the mounting seat 13 until it slowly contacts the clamping plate 62. When the clamping seat 51 contacts the clamping plate 62, the clamping seat 51 slowly squeezes the clamping plate 62, causing the clamping plate 62 to slowly move into the movable groove 12 until the clamping seat 51 passes through the clamping plate 62. At this time, the connecting sleeve 1 2 and the connecting sleeve 2 3 are released, and the clamping seat 51 is restricted by the clamping plate 62, realizing a snap-on fixed connection.

[0029] Furthermore, a driving block 63 is provided perpendicularly to the other end of the connecting plate 61, wherein a telescopic rod is provided in the middle of the connecting plate 61, so that the driving block 63 and the card plate 62 are displaced synchronously, and the driving block 63 extends into the second movable groove 131. The driving block 63 matches the second frustum 93. The driving block 63 is conical, and its inclined surface is opposite to the inclined surface of the second frustum 93.

[0030] When disassembling the connecting sleeve 1 2 and the connecting sleeve 2 3, the frustum 2 93 moves outward, thereby squeezing the driving block 63 to move into the movable groove 12. At the same time, the clamping plate 62 also moves into the movable groove 12, thereby releasing the restriction of the clamping seat 51, and then the connecting sleeve 1 2 and the connecting sleeve 2 3 can be taken out.

[0031] like Figure 1-2 As shown;

[0032] Positioning blocks 8 are evenly arranged on the inner periphery of the connecting sleeve 1 2 and the connecting sleeve 2 3, and positioning grooves 11 are symmetrically and evenly opened on the periphery of the connector 1. The positioning blocks 8 can be inserted into the positioning grooves 11. The positioning blocks 8 and the positioning grooves 11 facilitate the positioning and installation of the connecting sleeve 1 2 and the connecting sleeve 2 3, thereby improving the installation efficiency;

[0033] Furthermore, a fixing mechanism 7 is provided on the outside of the connecting sleeve 1 2 and the connecting sleeve 2 3. The fixing mechanism 7 includes a threaded spring piece 71. The threaded spring piece 71 is provided with several and annularly fixed on the outside of the connecting sleeve 1 2 and the connecting sleeve 2 3. The circle surrounded by them is used to install the cable body 4. A protrusion 72 is provided on the outward position of the inner side of the threaded spring piece 71. The outer periphery of the several threaded spring pieces 71 is threadedly connected with a screw sleeve 73. By rotating the screw sleeve 73 to move outward, it slowly approaches the protrusion 72, so that the protrusion 72 will squeeze the cable body 4, making the cable body 4 more firmly installed and not easy to fall off.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
