Description

Technical Field

[0001] The present application relates to the technical field of arc doors, and in particular to an arc door structure, medical experimental equipment and immunohistochemistry instrument. Background Art

[0002] As the requirements for batch production and automation of medical experimental equipment become higher and higher, a door structure that can be opened and closed is required to provide a closed environment for the operating space within the medical experimental equipment.

[0003] The door structure cover is arranged above the operating space, and usually adopts a flip cover structure. Specifically, a cover body is arranged above the medical equipment, and the cover body is hinged with the upper edge at the back of the working side. The operator pushes the edge of the cover body to make an arc movement to open the cover body to expose the workbench.

[0004] However, this structure requires the operator to use force for a long time, especially when the cover body needs to meet a certain avoidance space. At this time, the cover body is large in size and weight, and it takes a lot of force to open the cover body, which is not convenient to operate. Utility Model Content

[0005] The purpose of the present application is to provide a circular arc rotating door structure that allows smoother door opening and closing.

[0006] In the first aspect, the arc revolving door structure provided by the present application adopts the following technical solution:

[0007] A circular arc door structure, comprising:

[0008] A support frame, having an operation window, and being arranged above the operation space of the working equipment, wherein the support frame is provided with an arc-shaped guide structure; and

[0009] The arc door is provided with a limiting structure matched with the guide structure and has a travel of sliding up and down along the guide structure. When the arc door is in the upper position, the operating window is opened, and when the arc door is in the lower position, the operating window is sealed and covered.

[0010] By adopting the above technical solution, when opening and closing the door, the arc door slides up and down along the guide structure. Compared with the flip-type door structure, it occupies less space, and the limiting structure on the arc door cooperates with the guide structure on the support frame, so that the pushing and pulling of the arc door is smoother and more stable.

[0011] Optionally, the guide structure includes a plurality of guide wheel groups, each of which includes two guide wheels, and the plurality of guide wheel groups are arranged on the support frame at intervals along the sliding direction of the arc door;

[0012] The limiting structure includes an arc guide rail, which is installed on the arc door, inserted between the two guide wheels in each guide wheel group and slidably connected with the guide wheels.

[0013] By adopting the above technical solution, the arc guide rail is connected to the arc door, and the guide wheel group constrains the arc guide rail to prevent the arc door from deflecting during the process of pushing and pulling the arc door, and the pushing and pulling of the arc door is smoother.

[0014] Optionally, the guide wheel includes a rotating shaft mounted on the support frame, an upper roller and a lower roller rotatably connected to the rotating shaft and spaced apart from each other, and an end of the arc guide rail is wedged between the upper roller and the lower roller and abuts against each other.

[0015] Since the arc guide rail slides along the edge of the annular part of the support frame, and the arc guide rail has a certain thickness, when the arc guide rail slides, the linear speed between the inner and outer sides of the arc guide rail is not consistent, which makes the roller easily damaged. By adopting the above technical solution, the guide wheel is divided into an upper roller and a lower roller, and the upper roller and the lower roller rotate independently on the rotating shaft, which can effectively prevent the damage to the guide wheel caused by the inconsistent linear speed of the inner and outer sides of the arc guide rail.

[0016] Optionally, the guide structure further includes arc grooves arranged at both ends of the support frame, and the arc door has an up and down sliding stroke along the arc grooves.

[0017] By adopting the above technical solution, the arc groove cooperates with the arc door. When the arc door is pushed and pulled, the arc door moves along the opening track of the arc groove, thereby being limited, further preventing the possibility of the arc door being offset during the pushing and pulling process.

[0018] Optionally, it also includes a power-assisting member, one end of which is elastic and used to be connected to a working device or a support frame, and the other end of the power-assisting member is connected to the arc door to provide power to the arc door to slide from a lower position to an upper position.

[0019] By adopting the above technical solution, the power-assisting member provides a balancing force for pulling the moving arc door. When the arc door moves from the upper position to the lower position, the arc door automatically slides down due to gravity, making the movement of the arc door smoother.

[0020] Optionally, the power assist member includes a traction rope and a first elastic element, the first elastic element is used to be installed on the working equipment, one end of the traction rope is connected to the first elastic element, and the other end of the traction rope is connected to the arc door.

[0021] By adopting the above technical solution, when the arc door is pushed, the elastic element gradually shrinks back to its initial state, and the pulling force applied to the arc door is gradually reduced to adapt to the different position states of the arc door, making the entire pushing and pulling process smooth.

[0022] Optionally, a buffer component is also included, which is used to be installed on the working equipment and is located on the side of the support frame facing away from the operating space, and is used to abut against the arc door when it is in the upper position.

[0023] By adopting the above technical solution, when the arc door moves from the lower position to the upper position, it will contact the buffer component to protect the equipment.

[0024] Optionally, the buffer component includes a mounting seat and a second elastic element, the mounting seat is mounted on the support frame, one end of the second elastic element is connected to the mounting seat, and the other end of the second elastic element is used to abut against the arc door when it is in the upper position.

[0025] By adopting the above technical solution, when the arc door moves from the lower position to the upper position, the second elastic element balances the effect of gravity, and the buffer column provides a buffering effect in the process of pushing the arc door down, making the movement smooth, avoiding impact damage, and reducing the noise generated when opening the door.

[0026] Optionally, the buffer component further comprises a buffer column mounted on the mounting seat, the second elastic element is sleeved on the buffer column and allows the end of the buffer column to extend out;

[0027] A connecting plate is installed on one side of the arc door that can abut against the second elastic element, and a plug hole that matches the buffer column is provided on the connecting plate.

[0028] By adopting the above technical solution, before the connecting plate abuts against the second elastic element, the buffer column is inserted into the insertion hole to constrain the movement of the connecting plate and ensure the stability of the arc door when it moves to the lower position.

[0029] Optionally, it also includes a drag chain and a display screen arranged on the arc door, the drag chain is used to accommodate electrical circuits connected to the display screen, one end of the drag chain is connected to the support frame, and the other end of the drag chain is connected to the arc door.

[0030] By adopting the above technical solution, a display screen for controlling the device program will be provided on the revolving door, and the display screen is connected to the control board outside the revolving door through the electrical circuit, and the electrical circuit is guided by the drag chain to prevent the electrical circuit from being pulled and damaged when the revolving door is opened and closed.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. In this application, an arc door structure is provided to provide a closed environment for medical equipment. When opening and closing the door, the arc door slides up and down along the guide structure. Compared with the flip-type door structure, it occupies less space, and the limiting structure on the arc door cooperates with the guide structure on the support frame, so that the arc door can be pushed and pulled more smoothly and stably.

[0033] 2. In the present application, a power-assisting member is provided to provide a balancing force for pulling the moving arc door. When the arc door moves from the upper position to the lower position, the arc door automatically slides down due to overcoming gravity, making the movement of the arc door smoother.

[0034] 3. In the present application, a buffer is provided to protect the equipment. When the arc door moves from the lower position to the upper position, the second elastic element balances the effect of gravity, and the buffer column provides a buffering effect in the process of pushing the arc door down, so that the movement is smooth, avoiding impact damage, and reducing the noise generated when opening the door.

[0050] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0051] A medical experimental device, referring to Figure 1 and Figure 2 , including a working device 10 and an arc door 2 structure, the working device 10 has an operating platform 20, the arc door 2 structure is installed on the working device 10, and the two end surfaces of the arc door 2 are sealed. When the arc door is closed, a closed working environment can be provided for the working device 10, wherein the working device 10 can be a medical device (such as: an immunohistochemical instrument, a staining machine, a frozen slicer, etc.), or other experimental equipment. In this embodiment, the working device 10 uses an immunohistochemical instrument.

[0052] Reference Figure 1 The arc door 2 structure includes a support frame 1, which is arranged above the operating space 30 of the immunohistochemistry instrument and has an operating window 11. The support frame 1 is provided with an arc-shaped guide structure 3 and an arc door 2, and the arc door 2 has a travel that slides up and down along the guide structure 3.

[0053] The support frame 1 includes a support plate 12 and a U-shaped rod 13 located at both ends of the support plate 12. The two ends of the support plate 12 are respectively connected to the two U-shaped rods 13 in a one-to-one correspondence, so that one side of the support frame 1 is closed and an operation window 11 is formed on the other side. When the arc door 2 is in the upper position, the operation window 11 is opened, and the staff can put experimental equipment, raw materials and samples on the operating platform 20. When the preparation work is completed, the arc door 2 is pushed so that the arc door 2 is in the lower position to seal the operation window 11. The operating space 30 is closed to provide a closed environment for the experiment. At this time, the staff operates the working equipment 10 to conduct the experiment.

[0054] Correspondingly, it also includes a drag chain 9 and a display screen 8 arranged on the arc door 2. When the arc door 2 covers the operation window 11, the display screen 8 faces the staff. The staff inputs instructions on the display screen 8 to operate the working equipment 10, and the drag chain 9 is used to accommodate the electrical circuit connected to the display screen 8. The drag chain 9 is generally U-shaped, one end of which is connected to the support frame 1, and the other end is connected to the arc door 2 to facilitate wiring and prevent the electrical circuit from being damaged during the pushing and pulling of the arc door 2.

[0055] In addition, combined Figure 3 A limiting sleeve 70 and two groups of limiting columns 80 are provided on both sides of the limiting sleeve 70. In this embodiment, two limiting columns 80 form a group, and the two limiting columns 80 are diagonally distributed relative to the limiting sleeve 70. The limiting sleeve 70 is plugged into the drag chain 9. By setting the limiting sleeve 70 and the limiting column 80, the movement trajectory of the drag chain 9 is constrained.

[0056] Reference Figure 1 and Figure 2 The arc door 2 is correspondingly provided with a limiting structure 4 that cooperates with the guide structure 3. In one embodiment, the guide structure 3 includes an arc groove 32 arranged at both ends of the support frame 1, and a roller (not shown in the figure) is provided on the arc door 2. The roller slides in the arc groove 32 so that the arc door 2 has an up and down sliding stroke along the arc groove 32. When the arc door 2 is pushed to slide, the arc door 2 will slide along the opening direction of the arc groove 32, and the moving trajectory will be constrained by the arc groove 32 to improve the stability of the sliding arc door 2.

[0057] It should be noted that the arc groove here can be additionally opened on the side where the two U-shaped rods 13 are close to each other, or the U-shaped rod 13 can be integrally formed with the arc groove 32 on the side close to the arc door 2.

[0058] In another embodiment, the arc groove 32 may not be provided on the support frame 1, and the clearance between the U-shaped rod and the support plate 12 is matched to form a limiting space for limiting the arc door 2 for the insertion of the arc door 2, thereby achieving the same restraining effect as the arc groove 32.

[0059] Furthermore, combined with Figure 4 In other embodiments, the guide structure 3 includes a plurality of guide wheel groups, the number of guide wheel groups is preferably two groups, each guide wheel group includes two guide wheels 31, and the plurality of guide wheel 31 groups are arranged on the support plate 12 at intervals along the sliding direction of the arc door 2, and the limiting structure 4 includes an arc guide rail 41, which is installed on the arc door 2, inserted between the two guide wheels 31 in each guide wheel group and slidably connected to the guide wheel 31.

[0060] When the arc door 2 is pushed, the arc guide rail 41 installed on the arc door 2 will be guided and limited by the guide wheel 31 group, thereby facilitating the pushing of the arc door 2 and improving the stability of the sliding arc door 2.

[0061] In this embodiment, the guide structure 3 includes the above-mentioned arc groove 32 and guide wheel group, and the limiting structure 4 includes the above-mentioned arc guide rail 41, that is, the above-mentioned two methods of restraining the arc door 2 are simultaneously adopted to further improve the stability of the sliding arc door 2.

[0062] Furthermore, in other embodiments, a fixing seat 33 for mounting the guide wheel group is provided on the support plate 12, a mounting hole 331 is opened on the fixing seat 33, and a gear 34 is rotatably connected in the mounting hole 331. Correspondingly, a rack 43 capable of meshing with the gear 34 is installed on one side of the arc guide rail 41 close to the fixing seat 33.

[0063] Among them, the gear 34 is driven by a motor (not shown in the figure). When the motor rotates, the gear 34 will drive the rack 43 to make the arc guide rail 41 slide, and the automatic opening and closing of the arc door 2 can be realized through the forward and reverse rotation of the motor. In addition, a damper (not shown in the figure) can be connected to the other side of the gear 34 to prevent the process force from changing abruptly when opening and closing the arc door 2, so as to balance the force applied to the arc door 2.

[0064] When the revolving door is pushed or pulled, the arc guide rail 41 slides relative to the fixed seat 33. During the sliding process, the arc guide rail 41 will push the guide wheel 31 to rotate, and driven by the rack 43, the gear 34 will also rotate. The coordination between the rack 43 and the gear 34 ensures the smooth movement of the arc door 2.

[0065] It should be noted that, in other embodiments, the guide wheel 31 set and the gear 34 may also be directly installed on the support plate 12 to ensure the smooth movement of the arc door 2.

[0066] Reference Figure 4 and Figure 5 The guide wheel 31 includes a rotating shaft 311 installed on the support frame 1, an upper roller 312 and a lower roller 313 rotatably connected to the rotating shaft 311 and spaced apart from each other, and a chamfer is arranged around the side where the upper roller 312 and the lower roller 313 are close to each other, so that the end of the arc guide rail 41 can be wedged into the gap between the upper roller 312 and the lower roller 313. Correspondingly, the arc guide rail 41 is tapered on both sides along its own width direction, and abuts against the upper roller 312 and the lower roller 313.

[0067] When the arc door 2 is pushed, the movement trajectory of the arc guide rail 41 is an arc. In other words, the arc guide rail 41 makes a circular motion relative to the support frame 1. Since the arc guide rail 41 has a thickness, the linear speeds of the inner and outer sides of the arc guide rail 41 are inconsistent. The arc guide rail 41 is slidingly connected to the upper roller 312 and the lower roller 313 respectively, and the upper roller 312 and the lower roller 313 rotate independently, thereby preventing the inner and outer linear speeds of the arc guide rail 41 from being inconsistent when sliding, causing greater damage to the guide wheel 31.

[0068] In addition, rolling bearings 314 are provided in the upper roller 312 and the lower roller 313. The rolling bearings 314 are sleeved on the rotating shaft 311 to improve the smoothness of the rotation of the upper roller 312 and the lower roller 313 relative to the rotating shaft 311, so as to reduce the friction between the arc guide rail 41 and the upper roller 312 and the lower roller 313 when sliding, and further protect the guide wheel 31.

[0069] Reference Figure 1 In order to facilitate the staff to push and pull the arc door 2, a push handle 7 is installed on the side of the arc door 2 away from the arc guide rail 41.

[0070] Further, refer to Figure 6 and Figure 7 , and also includes a power-assisting member 5, one end of which is elastically connected to the working equipment 10 or the support frame 1. In this embodiment, the elastic end of the power-assisting member is connected to the working equipment 10. In other embodiments, the elastic end of the power-assisting member 5 can also be connected to the support frame 1. The other end of the power-assisting member 5 is overlapped on the support frame 1 and connected to the arc door 2, so as to provide power for the arc door 2 to slide from the lower position to the upper position.

[0071] Specifically, the assisting member 5 includes a traction rope 51 and a first elastic element 52. The number of the traction rope 51 and the first elastic element 52 can be one or more. In the present embodiment, the traction rope 51 and the first elastic element 52 are both arranged in two groups. The two groups of traction ropes 51 are arranged in one-to-one correspondence with the two groups of first elastic elements 52. The first elastic element 52 is preferably a spring, which is installed on the working equipment 10. One end of the traction rope 51 is connected to the first elastic element 52, and the other end of the traction rope 51 is connected to the arc door 2.

[0072] Taking the door opening action as an example, when the arc door 2 is in the lower position, the first elastic element 52 is in a stretched state, applying a pulling force to the arc door 2 to provide assistance to the staff when pushing the arc door 2 from the lower position to the upper position. It should be noted that in the process of the arc door 2 being pushed, the first elastic element 52 gradually shrinks back to the initial state, and the pulling force applied to the arc door 2 is gradually reduced to adapt to the different position states of the arc door 2 (when the arc door 2 is in different positions, the resistance encountered when pushing and pulling the arc door 2 is different, the resistance is the largest in the lower position, and the resistance is the smallest in the upper position), so that the entire pushing and pulling process is smooth.

[0073] It should be noted that in other embodiments, only the first elastic element 52 may be provided. The first elastic element 52 is provided in an arc shape, one end of which is connected to the arc door 2, and the other end is connected to the working equipment 10, so as to achieve the same power-assisting effect.

[0074] In the present embodiment, in order to further improve the stability of the sliding arc door 2, the traction rope 51 includes a first traction rope 511 and a second traction rope 512. Correspondingly, a pulley group 53 is provided on the working equipment 10, including a fixed pulley 531 and a movable pulley 532. The first traction rope 511 is overlapped with the movable pulley 532, one end of which is connected to the arc door 2, and the other end is connected to the working equipment 10, while the second traction rope 512 is overlapped with the fixed pulley 531, one end of which is connected to the first elastic element 52, and the other end is connected to the movable pulley 532.

[0075] The pulley block 53 and the traction rope 51 are arranged so as to better transmit the pulling force applied by the elastic element to the arc door 2 to the arc door 2 .

[0076] In addition, a supporting plate 40 is installed on the support plate 12. The supporting plate 40 is arranged in an arc shape and is used to support the first traction rope 511 to prevent the first traction rope 511 from being directly placed on the support plate 12 during the process of pushing and pulling the arc door 2, and scratching the support plate 12 after long-term pushing and pulling of the arc door 2.

[0077] Reference Figure 6 and Figure 7 , also includes a buffer member 6, which is installed on the working equipment 10 and is located on the side of the support frame 1 facing away from the operating space 30, and can be offset against the arc door 2 when it is in the upper position. Specifically, the buffer member 6 includes a mounting seat 61 and a second elastic element 62, the mounting seat 61 is installed on the support frame 1, one end of the second elastic element 62 is connected to the mounting seat 61, and the other end of the second elastic element 62 is used to offset the arc door 2 when it is in the upper position.

[0078] When the arc door 2 moves from the lower position to the upper position, the arc door 2 will contact and compress the second elastic element 62. The second elastic element 62 balances the gravity, so that the arc door 2 moves smoothly when its center of gravity moves downward.

[0079] Furthermore, the buffer member 6 further includes a buffer column 63 mounted on the mounting seat 61 to constrain the second elastic element 62 and prevent the second elastic element 62 from moving during compression. The number of the buffer column 63 and the second elastic element 62 may be one or more. In the present embodiment, two buffer columns 63 and two second elastic elements 62 are provided. The two buffer columns 63 are oppositely mounted on both sides of the mounting seat 61 and are arranged one-to-one with the two second elastic elements 62.

[0080] The second elastic element 62 is sleeved on the buffer column 63, and the end of the buffer column 63 is extended out, and a connecting plate 42 is installed on the side of the arc door 2 that can abut against the second elastic element 62. The connecting plate 42 is connected to the side of the arc guide rail 41 away from the arc door 2. A socket 421 matching the buffer column 63 is provided on the connecting plate 42. The aperture of the socket 421 is larger than the outer diameter of the buffer column 63 to facilitate the insertion of the buffer column 63.

[0081] Before the connecting plate 42 abuts against the second elastic element 62, the buffer column 63 is inserted into the insertion hole 421 to constrain the movement of the connecting plate 42. The buffer column 63 provides a buffering effect in the process of pushing the arc door 2 to fall backward, avoiding impact damage, and also reducing the noise generated when opening the door, thereby ensuring the stability of the arc door 2 when it moves to the upper position.

[0082] The implementation principle of the embodiment of the present application is: hold the push handle 7 to push the revolving door. At this time, the arc guide rail 41 located on one side of the arc door 2 will be constrained by the guide wheel 31, and the two ends of the arc door 2 will be constrained by the arc groove 32. In the process of pushing the revolving door, the first elastic element 52 applies a pulling force to the arc door 2 to make the door opening action smoother and smoother. When the arc door 2 reaches the upper position from the lower position, the second elastic element 62 gradually contracts to filter out the impact formed during the door opening action. The arc door 2 is finally covered on the support plate 12, which has the characteristics of small occupation area and smooth and stable pushing and pulling.

[0083] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
