[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a gear pump which is convenient for accurate wiring.

[0027] The utility model provides Figure 1-4 A gear pump that is easy to connect accurately as shown includes a pump body 1 and a male head 2 connected to the side wall of the pump body 1, a female head 3 is inserted inside the male head 2, a plurality of vertical rods 4 that are symmetrically arranged are fixedly provided on the outer side of the male head 2, a slide plate 5 is provided on the rod wall sliding sleeve of the vertical rod 4, a clamping block 6 is fixedly provided on the side close to the plurality of slide plates 5, the clamping block 6 is in contact with the outer wall of the female head 3, a fixing ring 7 is fixedly provided on the outer wall of the male head 2, an annular groove is provided on the outer wall of the fixing ring 7, a rotating pushing mechanism is provided inside the annular groove, the rotating pushing mechanism includes a swivel 8, the swivel 8 is rotatably sleeved in the annular groove, and a plurality of push rods 9 that are symmetrically arranged are fixedly provided on the outer wall, a plurality of slots that are symmetrically arranged are provided on the side wall of the swivel 8, the push rods 9 are in contact with the slide plates 5, and the longitudinal sections of the plurality of slide plates 5 are all wedge-shaped.

[0028] Before the pump body 1 is used, the position of the male head 2 is fixed. At this time, the female head 3 is inserted into the male head 2, and the swivel 8 is rotated, so that the swivel 8 rotates in the annular groove and drives multiple push rods 9, so that the push rods 9 start to push the slide plate 5 when they come into contact with the inclined surface of the slide plate 5, so that the slide plate 5 can drive the clamping block 6 to approach the female head 3 after being pushed, and clamp the female head 3 to position it, thereby ensuring the plug-in stability and accuracy of the female head 3 and the male head 2, and avoiding the cable from being detached during the use of the pump body 1 as much as possible.

[0029] In order to fix the position of the swivel 8 after the swivel 8 drives the multiple push rods 9 to push out and clamp, Figure 2-4 As shown, the outer wall of the swivel 8 is provided with a plug-in positioning mechanism for limiting the position of the swivel 8, and the plug-in positioning mechanism includes a sleeve 12, and the outer wall of the fixed ring 7 is provided with a groove, the groove is connected to the annular groove, and the inner wall of the groove is fixedly provided with a support rod 13, the sleeve 12 is slidably sleeved on the outer side of the support rod 13, the sleeve 12 is inserted into the slot, and the rod wall of the support rod 13 is sleeved with a second spring 14, and the two ends of the second spring 14 are respectively fixedly connected to the sleeve 12 and the support rod 13, and the outer wall of the sleeve 12 is fixedly provided with a pull rod 15, and the end of the pull rod 15 passes through the groove and extends to the outside.

[0030] Before the swivel 8 rotates, the pull rod 15 is pulled so that the pull rod 15 drives the sleeve 12 to separate from the inside of the swivel 8, so that the sleeve 12 slides on the outside of the support rod 13 and squeezes the second spring 14. After the swivel 8 rotates and the clamping block 6 squeezes the female head 3, the pull rod 15 is released, and the elastic force of the second spring 14 is restored, so that the sleeve 12 rebounds and is inserted into the slot on the side wall of the swivel 8 again, thereby fixing the position of the swivel 8, thereby ensuring that the extrusion position of multiple clamping blocks 6 is fixed.

[0031] In order to enable the clamping block 6 to be separated from the female head 3 after the push rod 9 is separated from the slide plate 5, so as to facilitate the separation of the female head 3 and the male head 2, as shown in FIG. Figure 2 As shown, the rod wall of the vertical rod 4 is provided with an elastic limiting mechanism, which includes a limiting block 10. The limiting block 10 is fixedly sleeved on the outer side of the vertical rod 4. The rod wall of the vertical rod 4 is sleeved with a first spring 11. The two ends of the first spring 11 are fixedly connected to the slide plate 5 and the limiting block 10 respectively.

[0032] Under normal circumstances, the clamping block 6 is away from the female head 3, and when the push rod 9 pushes the slide plate 5, the slide plate 5 drives the first spring 11 to stretch. When the push rod 9 and the slide plate 5 are away from each other, the elastic force of the first spring 11 is restored, so that the slide plate 5 drives the clamping block 6 to be away from the female head 3, which makes it easy to separate the female head 3 from the male head 2.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
