[0003] The surgical bed commonly used in the hybrid operating room is a catheter bed with front, rear, left and right tilt adjustment. When the bed board is tilted, it is necessary to brake the bed board to facilitate positioning of the patient without movement, and the sliding tendency of the bed board needs to be quickly locked. Utility Model Content

[0004] 1. Technical issues

[0005] The utility model aims to provide a locking device and an inclined catheter bed, which solve the problem of locking the bed board when the bed board is inclined to avoid the bed board having a sliding tendency.

[0006] (II) Technical solution

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A locking device comprises an inclined plate and a transverse plate, wherein a fixed seat is fixed on the inclined plate, a long rack is fixed on the transverse plate, a mounting cavity is provided on the fixed seat, through longitudinal strip holes are provided on the two side walls of the mounting cavity, a sharp tooth block which can move up and down is provided in the mounting cavity, a limiting shaft extending into the longitudinal strip hole is fixed on the sharp tooth block; limiting grooves located below the longitudinal strip holes are provided on the two side walls of the mounting cavity, a rubber block is fixed on the sharp tooth block, and the end of the rubber block is inserted into the limiting groove; a driving handle for driving the sharp tooth block to move toward the long rack is also provided on the fixed seat.

[0009] Preferably, the driving handle comprises a rotating rod rotatably mounted on the fixing seat, one end of the rotating rod extends into the pointed tooth block and is sleeved with a limiting sleeve, and the other end of the rotating rod is fixed with a rotating handle perpendicular thereto.

[0010] Preferably, a limiting opening for limiting the limiting sleeve is provided on the pointed tooth block.

[0011] Preferably, the fixing seat is further provided with a cover plate for shielding the installation cavity.

[0012] Preferably, the tooth pitch on the pointed tooth block is the same as the tooth pitch on the long rack.

[0013] This embodiment also proposes an inclined catheter bed, including a base, a bed board, an electric push rod and a cross roller guide rail, and also includes the locking device as described above, the inclined plate is rotatably installed on the base, the electric push rod is used to push the inclined plate to achieve forward and backward and left and right tilting movements, the cross roller guide rail is fixed on the inclined plate, the transverse plate is slidably installed on the cross roller guide rail, and the bed board is fixed on the inclined plate.

[0015] (III) Beneficial effects

[0016] When the bed board in which the catheter is inserted is tilted, the traverse plate has a tendency to slide relative to the inclined plate. After the sharp tooth block is pushed by the driving handle to abut against the long rack, the sharp tooth block forms a limit stop for the long rack due to the force in the sliding direction, so that the traverse plate will not slide. As the inclined plate tilts forward, backward, left and right, the traverse plate is also kept in a stopped state.

[0017] The sharp tooth block is guided and limited by the longitudinal strip holes to ensure the support function of the sharp tooth block in bearing and stopping. At the same time, the rubber block and the limiting groove cooperate to provide elastic force for the sharp tooth block. It has elastic force storage in the stopped state, and can quickly reset and center the sharp tooth block after releasing the sliding tendency force. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-Figure 4 As shown, a locking device is proposed in an embodiment of the utility model, which is applied to a catheter bed, including an inclined plate and a transverse plate. The inclined plate allows the transverse plate and the bed board to adjust their tilt angles forward, backward, left and right. In the inclined state, the transverse plate is carried by the bed board to produce a tendency to slide relative to it, so that in the inclined state, a force along the sliding direction is transmitted to the transverse plate. Therefore, it is necessary to stop the bed board and the transverse plate relative to the inclined plate. At this time, it can prevent the patient on the bed board from slipping, and the tilt angle can be adjusted within a certain range.

[0026] Specifically, a fixing seat is fixed on the inclined plate, a long rack is fixed on the transverse plate, a mounting cavity is provided on the fixing seat, through longitudinal strip holes are provided on the two side walls of the mounting cavity, a sharp tooth block that can move up and down is provided in the mounting cavity, a limiting shaft extending into the longitudinal strip hole is fixed on the sharp tooth block, and a limiting groove located below the longitudinal strip hole is provided on the two side walls of the mounting cavity, a rubber block is fixed on the sharp tooth block, and the end of the rubber block is inserted into the limiting groove;

[0027] The sharp tooth block is limited in the installation cavity by the longitudinal bar hole and the limiting shaft, and has only the tendency to move toward or away from the long rack, and the rubber block can provide the corresponding elastic force. Specifically, a driving handle is provided on the fixing seat to drive the sharp tooth block to move toward the long rack. When stopping is required, the driving handle pushes the sharp tooth block to abut against the long rack. Due to the sliding tendency of the long rack under the action of the transverse plate and the bed plate, a limiting stop is formed on the sharp tooth block. At this time, the sharp tooth block stops in the installation cavity, allowing the rubber block to generate an elastic force with reset, but the elastic force is not enough to make the sharp tooth block out of the limiting state. Among them, the tooth pitch on the sharp tooth block is the same as the tooth pitch on the long rack, which is convenient for quickly realizing the matching limit and improving the accuracy of alignment.

[0028] Only when the inclined state is restored and the long rack has no force exerted on the sharp tooth block in the direction of sliding tendency, the sharp tooth block can be reset and centered due to the restoring elastic force of the rubber block, which is convenient for the next locking operation.

[0029] In this embodiment, the locking is mainly achieved by the shearing force in the sliding trend direction, and can be quickly unlocked after the tilted state is reset, so that the bed board can be slid to move the relative position of the patient.

[0030] Among them, the driving handle is used to push the sharp tooth block close to the long rack for locking operation, and the driving handle includes a rotating rod rotatably installed on the fixed seat, one end of the rotating rod extends into the sharp tooth block and is sleeved with a limit sleeve, and the other end of the rotating rod is fixed with a rotating handle perpendicular to it. The rotating handle rotates the rotating rod, which will cause the sharp tooth block to produce a certain elastic effect with the rubber block, and when the sharp tooth block and the long rack are pushed to form a locking state, the rubber block can have a reset elastic force, which is convenient for rapid reset after releasing the locked state.

[0031] Specifically, a limiting opening for limiting the limiting sleeve is provided on the sharp tooth block, and the limiting sleeve is placed through the limiting opening to facilitate connection between the limiting sleeve and the rotating rod.

[0032] At the same time, a cover plate for shielding the installation cavity is also provided on the fixing seat. The installation cavity is shielded by the cover plate, and the internal sharp tooth block is further limited to prevent the internal parts from falling off.

[0033] On the basis of the above embodiments, the utility model also proposes an inclined catheter bed, comprising a base, a bed board, an electric push rod and a cross-roller guide rail, the locking device in the above embodiments, the inclined plate is rotatably installed on the base, the electric push rod is used to push the inclined plate to achieve forward and backward and left and right tilting movements, the cross-roller guide rail is fixed on the inclined plate, the transverse plate is slidably installed on the cross-roller guide rail, the bed board is fixed on the inclined plate, and after the inclined plate is pushed by the electric push rod, the inclined plate is tilted in the forward and backward and left and right directions relative to the base, and after tilting, the locking device is used to stop and lock the sliding of the transverse plate relative to the inclined plate.

[0034] Among them, the number of the electric push rods is two, one of which is arranged on the base on a side surface of the tilting plate in the front and rear tilting direction, and the other is arranged on the base on a side surface of the tilting plate in the left and right tilting direction. By respectively arranging the two electric push rods in the front and rear tilting directions, corresponding tilt adjustment can be achieved in the left and right tilting directions.

[0035] The electric push rod can be a telescopic air cylinder or a telescopic oil cylinder or a screw nut mechanism, which can push the tilting plate to produce angle changes and support.
