Description

Technical Field

[0001] This utility model belongs to the field of vacuum sterilization technology, specifically a large-scale pulsed vacuum sterilizer. Background Technology

[0002] The pulsed vacuum steam sterilizer, also known as a pre-vacuum pressure cooker, uses a vacuum pump to remove all air from the cooker, creating a vacuum state. Then, steam is introduced, and this process of alternating between vacuuming and steam filling is repeated multiple times. Finally, steam is introduced and maintained at a certain temperature and pressure inside the cooker for a certain period of time. This allows the steam to quickly diffuse and penetrate deep into the contents of the cooker, achieving an effective sterilization effect.

[0003] Large-scale pulsed vacuum sterilizers are large in size, and their door panels are also larger in area and weight. They are connected and installed on the equipment through hinges or bearing rods. However, there is no positioning mechanism after the door panel is opened, which makes it easy for the door panel to open and close accidentally, affecting the placement of the objects to be sterilized. Furthermore, it is easy for it to be opened further, leading to problems such as bumps and collisions, which poses certain safety hazards.

[0004] Therefore, a large-scale pulsed vacuum sterilizer was developed to address the shortcomings of existing technologies. Utility Model Content

[0012] Preferably, a slide rod is slidably engaged inside the slide cavity, and a support head is fixedly connected to one end of the slide rod near the hinge assembly. The other end of the support head passes through the slide cavity and the door panel body and extends into the interior of the hinge block and engages with the locking teeth. A return spring is abutted and connected to the other end of the slide rod, and the other end of the return spring abuts and is connected to the side of the inner wall of the slide cavity away from the hinge assembly.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Due to the hinge assembly, the hinge block and the drag-reducing ball bearings facilitate the opening and closing of the door panel. Under the constraints of the positioning shaft, spring, etc., the spring can limit the linkage sleeve and locking teeth. Then, the locking teeth are connected to the door panel to lock the door panel, ensuring that the opened door panel can be confined within a fixed range, avoiding arbitrary opening and closing. At the same time, it can also provide a buffer for accidental bumps to reduce the impact intensity.

[0018] 2. Due to the door panel design, the sliding cavity and through hole of this utility model allow the control component to be connected to the sliding rod and the abutment head via a connecting rope through the guide wheel. This enables the operator to simultaneously perform unlocking and opening / closing operations through the control component, reducing the operation process and effectively improving operational efficiency.

[0019] 3. Under the elastic restoring force of the return spring, this utility model can automatically push the slide rod and the abutment head, thereby realizing the automatic connection between the abutment head and the hinge assembly, thus achieving the effect of vibration locking the hinge assembly and the door panel, and keeping the opening and closing angle of the door panel body stable.

[0020] 4. Due to the design of the control components, under the constraints of the slide groove and the limiting groove, and through the elastic restoring force of the positioning spring, this utility model ensures that when the door panel is connected to the hinge assembly, the limiting block is located on the axis of the through hole. Thus, when the operator opens the door panel to pull the control handle or closes the door panel to push the control handle, the limiting block can pull the connecting rope, thereby causing the slide rod and the abutment head to move and disengage from the hinge assembly, achieving the effect of simultaneous unlocking during opening and closing operations.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 7 As shown, this utility model provides a large-scale pulsed vacuum sterilizer, including a door panel 2 and an adapter plate 1 integrally formed at its front end. The door panel 2 is embedded in the front of the adapter plate 1. Two hinge components 3 are connected to one side of the door panel 2.

[0031] The hinge assembly 3 includes a hinge block 31 fixedly connected to the side of the door panel 2. Several evenly distributed resistance-reducing balls 32 are movably embedded in the bottom of the hinge block 31. A linkage sleeve 33 is inserted inside the hinge block 31. Locking teeth 34 are provided on the outer surface of the linkage sleeve 33. One end of the linkage mechanism is connected to the control assembly 4, and the other end of the linkage mechanism is engaged with the locking teeth 34. Two upper and lower positioning shafts 36 are movably sleeved inside the linkage sleeve 33. A positioning rod 35 is fixedly connected between the two positioning shafts 36. The outer diameter of the positioning rod 35 is smaller than the inner diameter of the linkage sleeve 33. A spring 37 located between the two positioning shafts 36 is connected between the linkage sleeve 33 and the positioning rod 35. The two ends of the spring 37 are respectively connected to the inner wall of the linkage sleeve 33 and the outer surface of the positioning rod 35.

[0032] Due to the hinge assembly 3, the hinge block 31 and the drag-reducing ball bearing 32 facilitate the opening and closing of the door panel body 21. Under the constraints of the positioning shaft 36, the spring 37, etc., the spring 37 can restrict the linkage sleeve 33 and the locking tooth 34. Then, the locking tooth 34 is connected to the door panel 2 to lock the door panel 2, ensuring that the door panel 2 can be limited to a fixed range after opening, avoiding arbitrary opening and closing. At the same time, it can also provide a buffer for accidental bumps to reduce the impact intensity.

[0033] The adapter plate 1 includes an adapter plate body 11 integrally formed on the front of the sterilizer 5. The back of the adapter plate body 11 is provided with a connecting port 12 connected to the front end of the sterilizer 5. The front of the adapter plate body 11 is provided with a mounting groove 13 connected to the front end of the connecting port 12. The door panel 2 is embedded in the interior of the mounting groove 13.

[0034] The adapter plate body 11 has a dustproof opening 6 at the bottom of the mounting groove 13 on the front side. The upper end of the dustproof opening 6 is connected to the bottom of the inner cavity of the mounting groove 13, and the lower end of the dustproof opening 6 extends to the bottom of the front end of the adapter plate 1.

[0035] The front of the adapter plate body 11 is provided with two connecting grooves 14 that are connected to one side of the mounting groove 13. The hinge block 31 is rotatably connected to the connecting groove 14. The opposite sides of the two positioning shafts 36 are fixedly connected to the upper and lower ends of the inner cavity of the connecting groove 14. The bottom of the inner cavity of the connecting groove 14 is provided with a slot 15, and the resistance-reducing ball 32 is rotatably connected to the slot 15.

[0036] The door panel 2 includes a door panel body 21 that is embedded in the mounting groove 13 and fixedly connected to the same side of the two hinge blocks 31. The door panel body 21 has two sliding cavities 22 inside, and two through holes 23 located between the two sliding cavities 22 and the upper and lower ends of the control component 4. The upper and lower ends of the through holes 23 are respectively connected to the upper and lower ends of the control component 4 and the facing surfaces of the two sliding cavities 22.

[0037] Due to the configuration of the door panel 2, with the cooperation of the sliding cavity 22 and the through hole 23, the control component 4 can be connected to the sliding rod 24 and the abutment head 25 via the guide wheel 26 through the connecting rope 27. This allows the operator to simultaneously perform unlocking and opening / closing operations through the control component 4, reducing the operation process and effectively improving operation efficiency.

[0038] The slide cavity 22 is slidably engaged with a slide rod 24. One end of the slide rod 24 near the hinge assembly 3 is fixedly connected to a support head 25. The other end of the support head 25 passes through the slide cavity 22 and the door panel body 21 and extends into the interior of the hinge block 31 and engages with a locking tooth 34. The other end of the slide rod 24 is abutted and connected to a return spring 28. The other end of the return spring 28 is abutted and connected to the side of the inner wall of the slide cavity 22 away from the hinge assembly 3.

[0039] Under the elastic restoring force of the return spring 28, the slide bar 24 and the abutment head 25 can be automatically pushed, thereby realizing the automatic connection between the abutment head 25 and the hinge assembly 3, thus achieving the effect of vibration locking the hinge assembly 3 and the door panel 2, so that the opening and closing angle of the door panel body 21 remains stable.

[0040] The slide cavity 22 is rotatably connected to a guide wheel 26 located between the slide rod 24 and the through hole 23. A connecting rope 27 is threaded through the through hole 23. One end of the connecting rope 27 is connected to the control component 4, and the other end of the connecting rope 27 passes through the through hole 23 and extends into the interior of the slide cavity 22. After passing around the guide wheel 26, it is connected to the end of the slide rod 24 away from the hinge component 3.

[0041] The control component 4 includes a slide groove 41 formed on the front of the door panel body 21 and between the upper and lower through holes 23. The upper and lower ends of the slide groove 41 are respectively connected to the two through holes 23. The door panel body 21 also has a limiting groove 42 connected to the left and right sides of the slide groove 41. The slide groove 41 and the limiting groove 42 are slidably engaged with a limiting block 43 located on the extension line of the axis of the two through holes 23. The front of the limiting block 43 is fixedly connected to a slider 44. The front of the slider 44 passes through the slide groove 41 and extends to the front of the door panel body 21 and is fixedly connected to a control handle 45.

[0042] The door panel body 21 is also provided with an embedded groove 46 that is connected to the back of the slide groove 41. A positioning spring 47 is provided inside the embedded groove 46. One end of the positioning spring 47 is connected to the side of the inner wall of the embedded groove 46 away from the slide groove 41, and the other end of the positioning spring 47 passes through the embedded groove 46 and extends into the slide groove 41 and is connected to the limiting block 43.

[0043] Due to the configuration of the control component 4, under the constraints of the slide groove 41 and the limiting groove 42, and under the elastic restoring force of the positioning spring 47, it is ensured that when the door panel 2 is connected to the hinge component 3, the limiting block 43 is located on the axis of the through hole 23. Thus, when the operator opens the door panel body 21 to pull the control handle 45 or closes the door panel body 21 to push the control handle 45, the connecting rope 27 can be pulled by the limiting block 43, thereby causing the slide rod 24 and the abutment head 25 to move and disengage from the hinge component 3, thus achieving the effect of unlocking simultaneously during the opening and closing operations.

[0044] Working principle and usage process of this utility model:

[0045] Assemble the equipment as shown in the diagram;

[0046] When opening the door, grip the operating handle 45 and pull it outward. This will cause the slider 44 to drive the limiting block 43 to slide along the slide groove 41 and the limiting groove 42, causing the limiting block 43 to be misaligned with the axis of the through hole 23. This will cause the limiting block 43 to pull the connecting rope 27, and under the constraint of the through hole 23 and the slide cavity 22, as well as the cooperation of the guide wheel 26, it will pull the slide rod 24 and the abutment head 25, causing the teeth at the front end of the abutment head 25 to disengage from the locking teeth 34 on the outer surface of the linkage sleeve 33, thus completing the unlocking process.

[0047] Continue pulling the locking tooth 34. At this time, under the restriction of the limiting block 43 by the sliding groove 41 and the limiting groove 42, the door panel body 21 is pulled and swings along the mounting groove 13. At the same time, the upper and lower hinge blocks 31 on the other side of the door panel body 21 rotate along the connecting groove 14, thereby completing the opening of the door panel body 21. Then, release the operating handle 45. Under the elastic restoring force of the positioning spring 47, the limiting block 43 and the operating handle 45 are reset as a whole. Release the taut connecting rope 27. At the same time, under the elastic restoring force of the return spring 28, push the sliding rod 24 and the abutment head 25 so that the front end of the abutment head 25 engages with the locking tooth 34 on the outer surface of the linkage sleeve 33, thereby locking the door panel 2.

[0048] When closing the door, grip the control handle 45 firmly and push the control handle 45 forward, and the spring force will close the door panel body 21.

[0049] When the door panel body 21 remains open and is locked by the cooperation of the abutment head 25 and the locking tooth 34, it can provide a buffer in the event of an impact. The abutment head 25 and the locking tooth 34 drive the linkage sleeve 33 to rotate. Under the restriction of the positioning rod 35 and the positioning shaft 36, the spring spring 37 is twisted to deform and increase the elastic restoring force. After the impact ends, the door panel body 21 automatically resets under the action of the elastic restoring force of the spring spring 37.
