Description

Technical Field

[0001] The utility model belongs to the field of medical supplies, in particular to a bedside surgery support table. Background Art

[0002] The magnetic pump is a pump body that transmits torque through a magnetic field. A magnet is set on the inner wheel, and the power is transmitted to the outer wheel through the transmission shaft, thereby realizing the suction and discharge of the medium. It does not need to set up a traditional mechanical sealing device, avoiding leakage problems. Figure 1 As shown in the outer wheel casing, during the production process, a transmission hole for passing the transmission shaft needs to be set at the outer wheel casing of the magnetic pump, and a through hole is required to cross the transmission hole to facilitate the installation and fixing of the bearing. However, in the actual processing process, due to the different apertures of the through hole and the transmission hole, burrs are likely to appear at the intersection of the two holes during the drilling process, which causes troubles to the subsequent installation and use of parts. The burrs of the parts need to be removed after processing. However, since the edges of the intersection of the two holes are curved and need to be inserted into the hole for processing, ordinary scrapers are not convenient for operation. Utility Model Content

[0003] In view of this, the utility model aims to provide a bedside surgery support tabletop to facilitate doctors and nurses to perform surgery beside the patient's bed.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] A burr removal device for an outer wheel casing of a magnetic pump comprises a telescopic rod and a sleeve sleeved on the telescopic rod, a connecting block rotatably connected to one end of the telescopic rod, at least one scraper group is arranged on the periphery of the telescopic rod, and each scraper group comprises two blades, and one end of the two blades is hinged, the other end of one blade is hinged to the connecting block, and the other end of the other blade is hinged to the end of the sleeve, and when the sleeve moves toward the connecting block, the hinge of the two blades can move outward, and the cutting edge of each blade faces outward.

[0006] Furthermore, two scraper groups are provided on the periphery of the telescopic rod, and the scraper groups are symmetrically arranged with the axis of the telescopic rod as the center.

[0007] Furthermore, a spring is sleeved on the telescopic rod, and one end of the spring abuts against the end of the sleeve, and the other end abuts against the connecting block.

[0008] Furthermore, a plug connector is provided at the end of the telescopic rod, the connecting block is provided with a central hole, the connecting block is plugged with the plug connector, and a nut is threadedly connected to the end of the plug connector.

[0009] Furthermore, a support surface is provided at one end of the sleeve away from the connecting block, and a limiting portion extends outwardly from the telescopic rod. When the sleeve moves toward the connecting block to an extreme position, the limiting portion can be placed on the support surface.

[0010] Furthermore, the support table extends a blocking piece vertically upward, and when the telescopic rod and the sleeve are relatively rotated to the extreme position, the limiting portion can abut against the blocking piece.

[0011] Furthermore, the sleeve is provided with a receiving groove along the length direction, and when the sleeve moves in a direction away from the connecting block, the limiting portion can be placed in the receiving groove.

[0012] Furthermore, each blade is arc-shaped.

[0013] Furthermore, the edge of each blade is arc-shaped, and the top of the arc faces outward.

[0014] Furthermore, an angle is provided between the two blades in each scraper group in the length direction.

[0015] Compared with the prior art, the magnetic pump outer wheel housing burr removal device described in the utility model has the following advantages:

[0016] The utility model adopts a mutually hinged arrangement of two scrapers with blades facing outwards, and controls the outward opening angle of the ends of the scrapers through a telescopic rod, so that after the scrapers are inserted into a predetermined position in the hole, they can be opened outwards, so that the blades of the scrapers can contact the intersection of the two through holes of the outer wheel housing, so as to scrape off the burrs on the hole wall;

[0017] Two sets of scraper groups are generally used so that the two symmetrically arranged blades can contact the edges of the intersection of the two holes at the same time, so that the device only needs to pull or press the telescopic rod or sleeve during use, without the need to apply additional lateral force, which is more convenient for the user to apply force;

[0018] A spring is used to retract the blades on both sides after scraping off the burrs, making it easier for the device to pull out of the through hole;

[0019] The support table and the baffle are used to control the blade to maintain the blade posture after opening outwards through the telescopic rod and the sleeve, and to simultaneously rotate the sleeve and the telescopic rod through the telescopic rod to reduce the external force on the blade.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] The burr removal device for the outer wheel housing 5 of the magnetic pump described in the utility model comprises a telescopic rod 2 and a sleeve 1, wherein the telescopic rod 2 is inserted into the sleeve 1, and both ends of the telescopic rod 2 extend out of the sleeve 1, and one end of the telescopic rod 2 extends out of the sleeve 1 through a plug connector 21 along the axial direction, and an external thread is formed at the end of the plug connector 21, and the plug connector 21 is inserted into the central hole of a connecting block, so that the connecting block is rotatably connected to the end of the telescopic rod 2, and is screwed to the plug connector 21 through a nut 22, thereby limiting the connection rod. At least one scraper group is provided on the side of the telescopic rod 2, and each scraper group includes two blades 31, and one end of the two blades 31 is hinged, the other end of one blade 31 is hinged to the connecting block, and the other end of the other blade 31 is hinged to the end of the sleeve 1, and when the sleeve 1 moves toward the connecting block, the hinge of the two blades 31 can move outward, and the edge of each blade 31 faces outward. More specifically, in this embodiment, the scraper group is provided with two groups, and the two scraper groups are symmetrically arranged with the axis of the telescopic rod 2 as the center, one end of each blade 31 is provided with a second hinge ear 32, and the other end extends a third hinge ear 33 along the length direction of the blade 31, and the connecting block extends outward. A hinged ear 41, a fourth hinged ear 12 extends outward from one end of the sleeve 1 near the connecting block, the two blades 31 in each scraper group are hinged to each other through the third hinged ear 33, the second hinged ear 32 of the blade 31 near the connecting block is hinged to the first hinged ear 41 of the connecting block through a pin, the second hinged ear 32 of the other blade 31 is hinged to the fourth hinged ear 12, and the total length of the two blades 31 in each scraper group is greater than the maximum distance between the first hinged ear 41 and the fourth hinged ear 12, so that one end of the third hinged ear 33 of the two blades 31 can form an outwardly opened hinged ear, and when the sleeve 1 moves toward the connecting block, one end of the third hinged ear 33 of the two blades 31 can move outward. By using the two groups of scrapers arranged axially symmetrically, the scraper group is first extended into the area to be processed from the thinner through hole 52. When the scraper group reaches the preset position, the sleeve 1 is moved toward the connecting block to control the blades 31 of the two groups of scrapers to open outward so that the edge of the blade 31 corresponds to the area to be processed. Then, the telescopic rod 2 is pulled upward or the sleeve 1 is pressed downward so that the upper blade 31 or the lower blade 31 contacts the edge of the processed hole wall. At the same time, the telescopic rod 2 or the sleeve 1 is rotated so that the blade 31 rotates along the edge of the hole wall. Since the two groups of scrapers are arranged axially symmetrically, the positions where the blades 31 of the two scrapers contact the edge of the hole wall are also arranged axially symmetrically. Therefore, the force on the processed part of the hole wall is more uniform, and the hole wall is prevented from being scratched by the scraper while facilitating the user to apply force.

[0033] A support table 13 is provided at one end of the sleeve 1 away from the connecting block, and a limiting portion 23 extends outward from the telescopic rod 2. When the sleeve 1 moves to the extreme position in the direction of the connecting block, the limiting portion 23 can be placed on the support table 13. The sleeve 1 is provided with an accommodating groove 15 along the length direction. When the sleeve 1 moves in the direction away from the connecting block, the limiting portion 23 can be placed in the accommodating groove 15 to prevent the sleeve 1 from resetting when the external force is lost or the external force is uneven, which makes it easier for users to operate the device. The support table 13 extends a baffle 14 vertically upward. When the telescopic rod 2 and the sleeve 1 rotate relative to each other to the limit position, the limit portion 23 can abut against the baffle 14 to simplify the user's control of the device during the rotation process. The user only needs to press and rotate the telescopic rod 2 to make the telescopic rod 2 and the sleeve 1 rotate synchronously and apply external force to the edge of the hole wall to scrape off burrs, thereby avoiding the torsion force around the axial direction of the telescopic rod 2 applied by the telescopic rod 2 or the sleeve 1 alone, thereby avoiding deformation of the blade 31. The telescopic rod 2 is sleeved with a spring 11, and one end of the spring 11 abuts against the end of the sleeve 1, and the other end abuts against the connecting block. After the processing is completed, the telescopic rod 2 is rotated to the initial position, and the spring 11 can reset the telescopic rod 2 and the sleeve 1, so that the device can be quickly withdrawn from the hole after the processing is completed to process the next workpiece.

[0034] Each blade 31 is arc-shaped, and the edge of each blade 31 is arc-shaped, with the top of the arc facing outward, and an angle is provided in the length direction of the two blades 31 in each scraper group, and the opening direction of the angle is opposite to the arc opening direction of the blade 31, so that when the blade 31 rotates to scrape off the burrs, the burrs are guided into the hole to prevent the burrs from moving outward and contacting the hole wall and scratching the hole wall.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
