Abstract
Description
Technical Field
[0001] This invention belongs to the field of sterilizer technology, specifically an adaptive adjustment device and a pressure-type sterilizer using such a device. Background Technology
[0002] The hardware components of a common vertical sterilizer door closing signal detection system mainly include: door assembly, drive device, micro switch, and connecting assembly. The micro switch is set in a specific position, and a safety post is connected to the door or door beam. When the door moves to the closed position, the safety post presses the micro switch to generate a door closing signal, and the equipment proceeds to the next operation.
[0003] The microswitches used for signal detection are often plunger-type microswitches. The top of the plunger-type microswitch is very smooth and arc-shaped, with a raised center and lower edges. The matching safety post is a solid structure. Due to machining and installation errors of various parts of the equipment, as well as the positive and negative pressure changes generated during equipment operation, the door position may move slightly. The center position of the safety post and the center position of the plunger-type microswitch may be offset. When the offset angle is too large, the safety post may press against the plunger-type microswitch, creating a risk of it slipping off the arc-shaped top of the plunger, resulting in the loss of the door closing signal and thus interrupting the equipment program. Therefore, this door closing signal detection method needs improvement. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adaptive adjustment device and a pressure sterilizer using such a device. The adaptive adjustment device can adjust the XY degree of freedom of the safety column to adapt to the center position of the micro switch and ensure that the closing signal is not lost.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The adaptive adjustment device includes a mounting plate, a first floating seat, a first guide shaft, a second floating seat, a second guide shaft, and a safety column. The first floating seat is slidably mounted on the first guide shaft, and the second floating seat is slidably mounted on the second guide shaft. Two sets of second floating seats are symmetrically arranged at both ends of the first guide shaft. The first guide shaft and the second guide shaft are arranged perpendicular to each other. A first adjusting spring is provided on the first guide shaft on both sides of the first floating seat, and a second adjusting spring is provided on the second guide shaft on both sides of the second floating seat. The mounting plate is fixedly mounted at both ends of the second guide shaft, and the safety column is vertically arranged on the lower side of the first floating seat.
[0006] Preferably, a groove is provided on the bottom side of the safety post, and the groove is chamfered.
[0007] Preferably, the second floating seat is provided with a mounting block, which is connected to the first guide shaft.
[0008] Preferably, the first floating seat and the second floating seat are linear bearings.
[0009] A pressure sterilizer using an adaptive adjustment device includes a pressure sterilizer body, a pressure door, a micro switch, and a drive device. The micro switch is disposed on the pressure sterilizer body, the adaptive adjustment device is disposed on the pressure door, and the drive device is disposed on the pressure sterilizer body and drives the pressure door to move together with the adaptive adjustment device until the safety post of the adaptive adjustment device matches the micro switch.
[0010] Preferably, it also includes a door beam, a bracket, and a connecting plate. One end of the door beam is connected to the drive device, and the other end is connected to the pressing door. The bracket is set on the door beam, and one end of the connecting plate is connected to the bracket, while the other end is vertically connected to the mounting plate of the adaptive adjustment device.
[0011] Preferably, the first floating seat, the second floating seat, and the connecting plate are arranged in parallel.
[0012] Compared with existing technologies, the beneficial effects of this technical solution are:
[0013] This invention achieves free floating adjustment of the mounting column in the XY direction by setting a first floating seat and a second floating seat. The first floating seat is vertically connected to the second floating seats symmetrically arranged on both sides of the first floating seat via a first guide shaft. The first floating seat has a first adjusting spring that can float freely on the extension section of the first guide shaft at both ends, which can achieve floating adjustment in the X direction when a force is applied. The second floating seat is connected to the mounting plates arranged on both sides of the second floating seat via a second guide shaft. The second floating seat also has a second adjusting spring that can float freely on the extension section of the second guide shaft on both sides of the second floating seat, which can drive the second floating seat and indirectly drive the first floating seat to achieve floating adjustment in the Y direction when a force is applied. Therefore, when the safety column set on the lower side of the first floating seat cooperates with the micro switch, if the center does not match and cannot be aligned, the safety column can achieve floating adjustment in the XY direction under the force of the micro switch, so that it can fully cooperate with the micro switch. The structure is simple. Attached Figure Description

Detailed Implementation
[0018] Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.
[0019] Reference Figures 1-2 A pressure-fitting sterilizer using an adaptive adjustment device includes a pressure-fitting sterilizer body 6, a pressure-fitting door 1, a micro switch 7, a drive device, and an adaptive adjustment device. The drive device of this invention is an electric push rod 2, which is connected to a door beam 3 and indirectly drives the pressure-fitting door 1, which is mounted on the door beam 3, to move. A bracket 4 is mounted on the door beam 3. The adaptive adjustment device is connected to the bracket 4 through a connecting plate 5. When the electric push rod 2 drives the pressure-fitting door 1 to move along a certain path, the adaptive adjustment device moves together. The micro switch 7 is a plunger-type micro switch, which is set at a specific position on the pressure-fitting sterilizer body 6. When the pressure-fitting door 1 is closed, the adaptive adjustment device matches the micro switch 7 to generate a door closing signal, and the equipment proceeds to the next operation.
[0020] Reference Figure 3 The adaptive adjustment device includes a mounting plate 8, a first floating seat 11, a first guide shaft 12, a second floating seat 13, a second guide shaft 14, and a safety post 9. The first floating seat 11 is installed in conjunction with the first guide shaft 12, and the second floating seat 13 is installed in conjunction with the second guide shaft 14. There are two sets of the second floating seat 13 and the second guide shaft 14, which are symmetrically arranged at both ends of the first guide shaft 12. The first floating seat 11 and the second floating seat 13 are arranged perpendicular to each other. A first adjusting spring 10 is provided on the extension section of the first guide shaft 12 on both sides of the first floating seat 11, and a second adjusting spring 16 is provided on the extension section of the second guide shaft 14 on both sides of the second floating seat 13. The mounting plate 8 is vertically arranged at both ends of the second guide shaft 14, and the safety post 9 is vertically arranged on the lower side of the first floating seat 11.
[0021] Specifically, the first floating seat 11 and the second floating seat 13 of this utility model are linear bearings. There is one set of the first floating seat 11 and two sets of the second floating seat 13. The two second floating seats 13 are arranged in parallel, and the first floating seat 11 and the second floating seat 13 are arranged perpendicularly and are located in the middle position of the two second floating seats 13.
[0022] The first floating seat 11 is installed in conjunction with the first guide shaft 12. The first guide shaft 12 is a shaft with one side that is not arc-shaped. The first adjusting spring 10 is set on the extension section of the first guide shaft 12 on both sides of the first floating seat 11, with one end connected to the first floating seat 11 and the other end connected to the second floating seat 13.
[0023] The second floating seat 13 is installed in conjunction with the second guide shaft 14. The second adjusting spring 16 is set on the extensions of the second guide shaft 14 on both sides of the second floating seat 13, with one end connected to the second floating seat 13 and the other end connected to the mounting plate 8. A mounting block 15 is provided on the side of the second floating seat 13 near the first floating seat 11. The first adjusting spring 10 passes through the extension of the first guide shaft 12 and connects the first floating seat 11 and the mounting block 15 respectively. The elastic force generated by the two first adjusting springs 10 makes the first floating seat 11 located at the center position of the two mounting blocks 15 in the natural state, and achieves free floating adjustment in the X direction when subjected to force.
[0024] Vertical mounting plates 8 are provided at both ends of the second guide shaft 14. The mounting plates 8 are connected to the connecting plate 5. The connecting plate 5 is horizontally positioned, and the mounting plates 8 are vertically positioned below the connecting plate 5. The second floating seat 13 is positioned between the two mounting plates 8 and is parallel to the connecting plate 5. The elastic force generated by the second adjusting springs 16 on both sides of the second floating seat 13 ensures that the second floating seat 13 is located at the center position of the two mounting plates 8 in its natural state. When subjected to force, it can achieve free floating adjustment in the Y direction, thereby driving the first adjusting seat 11 to achieve free floating adjustment in the Y direction.
[0025] A safety post 9 is provided on the lower side of the first floating seat 11. The bottom side of the safety post 9 has a groove with a certain draft angle, and the edge of the groove is chamfered. When the pressure door 1 is closed, the safety post 9 matches the plunger-type micro switch, and the column at the top of the micro switch 7 is inserted into the groove of the safety post 9. Unlike a solid safety post 9, when the position is offset, because of the groove on the bottom side of the safety post 9, the safety post 9 will not slide directly away from the micro switch 7, but will be hooked on the column of the micro switch 7. The adaptive adjustment device adjusts the position of the safety post 9 so that the center groove of the safety post 9 is completely matched with the center of the plunger on the micro switch 7, generating a door closing signal.
[0026] Work process:
[0027] When the equipment issues a door-closing command, the electric push rod 2 extends, driving the pressing door 1, door beam 3, and bracket 4 to move. The motion is transmitted to the adaptive detection device through the connecting plate 5. The adaptive detection device moves according to the specified motion path. Ideally, when the equipment reaches the closed position, the center groove of the safety column 9 coincides with the center of the plunger-type micro switch. However, due to the presence of machining and installation errors of various parts of the equipment, as well as the slight movement of the door position caused by the positive and negative pressure changes during equipment operation, the center position of the safety column 9 and the center position of the plunger-type micro switch may be relatively offset. At this time, the top of the plunger contacts the edge of the safety column 9 and exerts a pushing force on the safety column 9 in a direction perpendicular to the chamfer of the groove of the safety column 9. At the same time, the first adjusting spring 10 on both sides of the first floating seat 11 and the second adjusting spring 16 on both sides of the second floating seat 13 are squeezed by this force and move adaptively in the XY plane, so that the center position of the safety column 9 adapts to the plunger position. As the electric push rod 2 continues to extend, the plunger is inserted into the groove at the bottom of the safety column 9 and receives pressure to contract downward, generating a door-closing signal.
[0028] When the device executes the door opening command, the electric push rod 2 retracts and the adaptive detection device moves upward. At this time, as the safety column 9 separates from the plunger-type micro switch, the linear bearing of the adaptive detection device moves to the initial position. When the two are completely separated, the safety column 9 returns to the initial position due to the spring 10, avoiding error accumulation and not affecting the next program operation.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
