For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] The tube cutting device in the present application is mainly used for the initial cutting of incoming tube materials for medical devices. Specifically, by changing the structure of the cutting device, the cutting quality of the incoming tube materials is improved and the cutting operation efficiency is improved.

[0043] See also Figure 1 , and combined with Figure 3-Figure 8 The pipe cutting device in the utility model comprises a housing 1, a slide rail 2 is arranged on the housing 1, a slide block 3 is installed on the slide rail 2, and a blade 4 installed obliquely is arranged on the slide block 3;

[0044] The top of the shell 1 is provided with a plurality of receiving grooves 11 for placing pipes. The plurality of receiving grooves 11 are arranged in parallel, and the extension direction of the receiving grooves 11 is perpendicular to the arrangement direction of the slide rail 2. The pipes are connected to the lower part of the slide rail 2, and the slider 3 can drive the blade 4 to cut the pipes.

[0045] By setting the slide rail 2 and the slider 3 , the slider 3 can load the blade 4 to move forward and backward relative to the slide rail 2 , and the pipe passing through the lower part of the slide rail 2 can be cut by the inclined blade 4 .

[0046] The inclined installation of the blade 4 can improve the cutting quality of the pipe. The blade 4 is specifically a double-edged blade 4. Through the sliding process of the slider 3 on the slide rail 2, the double-edged blade 4 passes through the pipe, thereby realizing the cutting of the pipe.

[0047] During installation, the pipe is placed in the receiving groove 11 on the top of the shell 1. The receiving groove 11 is specifically in the form of a sinking groove, which is convenient for the placement of the pipe. At the same time, the pipe passes through the slide rail 2 to facilitate cutting during the sliding process of the slider 3.

[0048] The arrangement of the plurality of accommodating grooves 11 facilitates the placement of a plurality of pipes, facilitates the cutting of a plurality of pipes in one slide, and improves the cutting efficiency.

[0049] The mutually parallel receiving grooves 11 can keep multiple pipes in a parallel placement state. Combined with the extension direction of all the receiving grooves 11 being perpendicular to the arrangement direction of the slide rail 2, multiple pipes can be perpendicular to the slide rail 2. Combined with the sliding of the slider 3 loading the blade 4 on the slide rail 2, the straightness of the pipe cut can be ensured.

[0050] A plurality of through holes 21 are provided at the lower part of the slide rail 2. The through holes 21 correspond to the receiving grooves 11 one to one, and the through holes 21 are directly opposite to the receiving grooves 11, so that the pipes can be arranged in a straight line after passing through the through holes 21, thereby ensuring the flatness of the cutting part.

[0051] When the slider 3 slides on the slide rail 2, it can drive the blade 4 to cut the pipe passing through the slide rail 2 to complete the overall cutting operation.

[0052] In one of the specific embodiments, the blade 4 is arranged obliquely relative to the slider 3. The blade 4 is specifically a square thin sheet structure, and a double-sided blade is arranged at the bottom thereof to constitute a cutting double edge. Based on the inclined setting, at least a portion of the cutting double edge at the bottom of the blade 4 is exposed at the bottom of the slider 3. When the slider 3 slides relative to the slide rail 2, the exposed cutting blade of the load-bearing blade 4 can slide through the pipe and cut the pipe connected to the slide rail 2.

[0053] In this embodiment, in order to ensure that the cutting double edges of the blade 4 can be exposed, the angle of the blade 4 of the square sheet relative to the horizontal direction is 30-60°, preferably 30-45°, so that the cutting double edges can be fully exposed.

[0054] For ease of assembly, the cutting blade 4 is specifically installed on the slider 3 by clamping. In another specific embodiment, the slider 3 includes two blocks 31 that are butt-jointed and assembled, and the blade 4 is installed between the two blocks 31. The two blocks 31 are respectively provided with positioning pins 34 and pin holes 35 and are fastened together by screws.

[0055] During the process of clamping the blocks 31, the two blocks 31 can be clamped and fixed by fastening with screws to ensure the stability of the blade 4 on the slider 3. At the same time, the slider 3 can be slidably assembled on the slider 2 through the cooperation between the groove 32 on the block 31 and the slider 2.

[0056] Furthermore, an assembly hole 41 is provided on the blade 4, wherein a positioning pin 34 on one block 31 passes through the assembly hole 41 on the blade 4 and is inserted into a pin hole 35 on another block 31. After the insertion and assembly, the fastening screw 36 is inserted into the connection hole 37 on the block 31 for fastening.

[0057] In order to ensure the limited sliding between the slider 3 and the slide rail 2, the two-way side walls of the slide rail 2 are provided with snap-fit ​​fins 22 for the slider 3 to snap-fit, and the grooves 32 of the two blocks 31 are both provided with snap-fit ​​grooves 33 that cooperate with the snap-fit ​​fins 22 for positioning.

[0058] By means of this arrangement, the slider 3 loaded with the blade 4 can be slidably and position-limitedly mounted on the slide rail 2, thereby ensuring the cutting of the pipe passing through the slide rail 2.

[0059] It should be noted that the slide rail 2 has a certain width, and the slide rail 2 is detachably mounted on the housing 1 through a slot provided on the housing 1. A vertical gap is provided on the slide rail 2, which enables the blade 4 to extend into the gap and cut the pipe that passes through the slide rail 2 horizontally.

[0060] Combination Figure 2 The pipe cutting device in the utility model is mainly used to cut pipe materials of the same length from the same batch. The lengths of pipes from different batches are different. From the perspective of being able to adjust the cutting length of the pipes, a clamping groove 12 is provided inside the shell 1. A movable adjusting clamping plate 5 is provided in the clamping groove 12. The position of the end of the pipe in the accommodating groove 11 is adjusted by adjusting the clamping plate 5, so that the blade 4 is located in the middle of the pipe, and each pipe is divided into two during cutting.

[0061] In order to facilitate adjustment, the adjustment clamping plate 5 is connected to a clamping block 51 exposed on the side of the shell 1 , and the clamping block 51 can be used to conveniently drive the adjustment clamping plate 5 to move and adjust.

[0062] The extension direction of the adjustment clamping plate 5 is perpendicular to the extension direction of the receiving groove 11, and the clamping groove 12 is connected to the receiving groove 11. Further, the clamping groove 12 is a hole structure extending into the interior of the housing 1 and has a certain length. The adjustment clamping plate 5 is arranged in the clamping groove 12 and can move relative to the axial direction of the receiving groove 11, so that the wall surface of the adjustment clamping plate 5 is abutted against the end of the pipe to form a clamping state for sorting and adjustment.

[0063] In this embodiment, the positioning grooves 12 and the adjusting clamping plates 5 include two groups, which are respectively arranged on both sides of the slide rail 2, and can respectively adjust the positioning of the two side ends of the pipe.

[0064] In order to facilitate the length positioning and ensure cutting in the middle of the tube, a positioning scale 13 is provided on the top wall of the shell 1, and a cutting slit 23 for inserting the blade 4 is provided in the center of the slide rail 2. The zero position scale line 14 of the positioning scale 13 is provided in the middle of the shell 1 and coincides with the cutting slit 23.

[0065] Gradually enlarged scale lines are symmetrically arranged on both sides of the zero scale line 14, which can be combined with the adjustment clamp 5 to make the center of the pipe correspond to the zero scale line 14, reducing the measurement of manual rulers, improving cutting efficiency and ensuring cutting accuracy.

[0066] In order to facilitate the taking and placing of pipes, taking and placing grooves 15 are respectively arranged on both sides of the receiving groove 11. The taking and placing grooves 15 are communicated with multiple receiving grooves 11. The taking and placing grooves 15 and the receiving grooves 11 are preferably in the form of sinking grooves. The taking and placing grooves 15 have a certain width, and the width of the taking and placing grooves 15 is at least 4-5 times the width of the receiving groove 11. The extension direction of the taking and placing grooves 15 is perpendicular to the extension direction of the receiving grooves 11, and the taking and placing grooves 15 are in a communicated form with multiple receiving grooves 11, which can facilitate the placement and removal of pipes in the taking and placing grooves 15 and reduce the difficulty of operation.

[0067] A buckling cover plate 6 is connected to the shell 1, and an avoidance notch 61 for avoiding the slide rail 2 and the slider 3 is set in the middle of the buckling cover plate 6. The buckling cover plate 6 can be buckled and fixed to the pipe placed in the receiving groove 11 at the top of the shell 1. The avoidance notch 61 does not hinder the sliding of the slider 3 on the slide rail 2, thereby meeting the normal cutting operation.

[0068] The pipe cutting device of the utility model opens a pipe receiving groove 11 according to the original length of the pipe to be cut, and the cutting slide rail 2 is installed in the middle position of the receiving groove 11. A through hole 21 for the pipe to pass through is reserved at the position of the slide rail 2 corresponding to the receiving groove 11, so that the pipe can pass through the through hole 21.

[0069] A double-edged blade 4 is installed in the cutting slider 3, which is installed at an angle on the slider 3. The slider 3 is then pushed and installed on the slide rail 2 through the groove 32, and is positioned and assembled through the snap-fit ​​fin 22 and the snap-fit ​​groove 33 on the groove 32. The cutting slider 3 is moved forward and backward through the cooperation between the snap-fit ​​fin 22 and the snap-fit ​​groove 33.

[0070] By adjusting the clamping plate 5 , the position of the pipe in the receiving groove 11 can be flexibly adjusted according to the different lengths of the pipe, so that the center of the pipe is opposite to the position of the blade 4 on the slide block 3 .

[0071] The pipe cutting device in the utility model can cut the pipe passing through the slide rail 2 by means of the inclined blade 4, so as to ensure that the cut of the pipe after cutting is flat and smooth without bevel and hair, thereby improving the cutting quality and the cutting efficiency.

[0072] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
