[0020] Example

[0021] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3 As shown, this embodiment is a rubber tube pressing device, including a bracket 1, a lower positioning seat 4 and an upper positioning block 3. A cylinder 2 is installed on the top of the bracket 1, one end of the cylinder 2 passes through the upper positioning block 3, and its telescopic end is connected to a pressing plate 5; the lower positioning seat 4 is arranged on the lower side of the upper positioning block 3, and a U-shaped clamping block 6 is embedded in the middle of the lower positioning seat 4. The cylinder 2 drives the upper positioning block 3 and the pressing plate 5 to move downward, so that the upper positioning block 3 contacts the lower positioning seat 4, and the pressing plate 5 moves further downward toward the U-shaped clamping block 6; specifically, when the utility model is in use, first Put the aluminum foil insulation sleeve on the outside of the rubber tube, and put a certain section of it in the U-shaped tube clamping block 6. The cylinder 2 drives the pressure plate 5 and the upper positioning block 3 to move downward as a whole. When the operator sees that the edge of the upper positioning block 3 is flush with the edge of the lower positioning seat 4, it is ensured that the pressure plate 5 is just pressing on the top of the rubber tube. The pressure plate 5 cooperates with the wrapping of the U-shaped tube clamping block 6, so that the aluminum foil insulation sleeve can evenly cover and fit tightly on the surface of the rubber tube. After the cylinder 2 is raised, the operator can move the pipe forward for a section and then press it for another section. The operation is convenient and simple.

[0022] Reference Figure 1 and Figure 3 As shown, the lower positioning seat 4 in this embodiment is detachably connected to the U-shaped tube clamping block 6, and the lower positioning seat 4 is provided with a locking groove 41. The lower end of the U-shaped tube clamping block 6 is provided with a limiting protrusion 61 that is inserted into the locking groove 41 in cooperation with the locking groove 41; specifically, the U-shaped tube clamping block 6 can be replaced according to rubber tubes of different diameters, and has a wider range of applications. After the limiting protrusion 61 of the U-shaped tube clamping block 6 is inserted into the locking groove 41, the U-shaped tube clamping block 6 can be prevented from rotating and displacing during the pressure application of the pressure plate 5.

[0023] In order to prevent the U-shaped clamping tube block 6 from being lost in the axial position, limit screws 8 are installed on the end faces of both sides of the lower positioning seat 4, and the U-shaped clamping tube block 6 is pressed and fixed by the limit screws 8, so that the U-shaped clamping tube block 6 cannot swing horizontally.

[0024] The side end surface of the bracket 1 in this embodiment is installed with a guide rail 11, and the upper positioning block 3 is slidably connected to the guide rail 11, so that the upper positioning block 3 moves up and down more smoothly.

[0025] Reference Figure 1 and Figure 2 As shown, an escape slot 31 is provided in the middle of the upper positioning block 3 in this embodiment. When the upper positioning block 3 contacts the lower positioning seat 4 , the upper end of the U-shaped clamping tube block 6 is accommodated in the escape slot 31 .

[0026] In addition, the pressing plate 5 adopts an arc structure, and the arc range of the pressing plate 5 is 80°-100°; specifically, in order to ensure that the contact area between the pressing plate 5 and the hose is larger during the pressing process of the pressing plate 5, a pressing plate 5 with a smaller arc is used for compression.

[0027] In order to facilitate the operator to perform compression control, the present embodiment further includes an air-controlled switch 7, which is connected to the air pipe of the cylinder 2. The cylinder 2 can be controlled to move downward and upward by pressing the control switch.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
