[0027] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0028] Refer to Figures 1-5 ,

[0029] A ferrule pre-installer includes: a pre-installer body 1, a pre-installed baffle 2, and a sleeve 3. The pre-installer body 1 includes a push rod 4 and an installation groove 5 located on the opposite side of the push rod 4. The push rod 4 can approach and move away from the installation groove 5 along its own axis. The installation groove 5 forms a sliding connection with the pre-installed baffle 2, so that the pre-installed baffle 2 can be detached from the installation groove 5, facilitating the replacement of the pre-installed baffle 2. A support notch is formed through from the upper end to the middle of the pre-installed baffle 2, and the support notch is used to support the pipe when the push rod 4 pushes the ferrule towards the pipe. The sleeve 3 is connected to one end of the push rod 4 facing the installation groove 5 through a pin. When the push rod 4 moves towards the installation groove 5, the sleeve 3 is docked with the ferrule and pushes the ferrule to be pre-installed on the pipe.

[0030] In another embodiment, the pre-installed baffle 2 forms a convex edge 6. The convex edge 6 is docked with the lower end of the support notch. The convex edge 6 contacts the pipe and provides upward support to the pipe, and the convex edge 6 extends in the length direction towards the push rod 4, increasing the contact length with the pipe to improve the guiding accuracy of the pipe, so that the pre-installation accuracy of the ferrule and the pipe is higher.

[0031] Specifically, it further includes a limit block 7. The limit block 7 is connected to the pre-installed baffle 2. The limit block 7 forms a first semi-circular groove 8, and a second semi-circular groove 9 is formed at the convex edge 6 of the pre-installed baffle 2. The first semi-circular groove 8 and the second semi-circular groove 9 are butt-jointed to form a circular through-hole. The axis of the circular through-hole coincides with the axis of the push rod 4. The pipeline passes through the circular through-hole and the axis of the pipeline coincides with the axis of the circular through-hole. The limit block 7 presses the pipeline onto the convex edge 6 from top to bottom, thereby preventing the pre-assembly accuracy of the ferrule and the pipeline from decreasing due to the shaking of the pipeline.

[0032] Specifically, the limit block 7 forms a sliding groove 10, and the sliding groove 10 is slidably engaged with the edge of the support notch to form a detachable connection. The operator can take out the limit block 7 from the upper end of the support notch by sliding it upward, so as to insert the ferrule and the pipeline into the pre-installer body 1. Then, align the sliding groove 10 of the limit block 7 with the upper end of the support notch and slide it downward from the upper end of the support notch to press the limit block 7 onto the pipeline.

[0033] Specifically, the edge of the pre-installed baffle 2 is slidably engaged with the installation groove 5, so that the pre-installed baffle 2 can slide longitudinally relative to the installation groove 5. The pre-installed baffle 2 and the installation groove 5 form a detachable connection, thereby facilitating the replacement of the pre-installed baffle 2.

[0034] Specifically, it further includes a cover plate 11. The cover plate 11 is rotatably connected to the pre-installer body 1. Specifically, the cover plate 11 is hinged to the pre-installer body 1. When the push rod 4 pushes the ferrule, the operator rotates the cover plate 11 to cover above the push rod 4 to prevent the fingers from accidentally touching the push rod 4 and causing injury. When it is necessary to insert and take out the ferrule and the pipeline from the pre-installer body 1, rotate the cover plate 11 to open the upper part of the push rod 4.

[0035] Working process: The operator rotates the cover plate 11 to open the upper part of the push rod 4, and then slides the limit block 7 upward along the edge of the support notch. The operator sleevs the ferrule on one end of the pipeline, and then puts this end of the pipeline into the pre-installer body 1, so that the ends of the ferrule and the pipeline are located between the pre-installed baffle 2 and the sleeve 3. The operator aligns the sliding groove 10 of the limit block 7 with the upper end of the support notch, and then slides the limit block 7 downward from the support notch, so that the first semi-circular groove 8 and the second semi-circular groove 9 are butted to clamp the pipeline and provide guidance. The operator starts the pre-installer body 1, and the push rod 4 moves towards the pre-installed baffle 2, so that the sleeve 3 abuts against the ferrule and pre-assembles the ferrule at the end of the pipeline.

[0036] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
