Description

Technical Field

[0001] The present application relates to the technical field of workshop equipment, and in particular to a circuit breaker shaft sleeve workpiece storage and retrieval rack. Background Art

[0002] The circuit breaker sleeve is a crucial component in the circuit breaker's mechanical structure. It supports and secures the breaker's rotating shaft (operating axis), ensuring stable rotation and transmitting operating force. It is typically cylindrical or stepped cylindrical (with a flange at one end) and has a central through-hole for the shaft.

[0003] During the production process of circuit breaker sleeves in a workshop, the processed circuit breaker sleeve workpieces usually need to be placed on a storage and retrieval rack. After a certain number of circuit breaker sleeve workpieces are placed on the storage and retrieval rack, the circuit breaker sleeve workpieces are transported by moving the storage and retrieval rack to facilitate the circuit breaker sleeve workpieces to be sent to another processing equipment for the next process.

[0004] However, in the process of placing and transporting circuit breaker sleeve workpieces on the existing storage and retrieval rack, the circuit breaker sleeve workpieces are easily exposed to the air in the workshop for a long time. In addition, the circuit breaker sleeves are easily affected by the vibration during the movement of the storage and retrieval rack due to factors such as unstable placement position and excessive placement and stacking, which will affect the structural strength and additional performance (such as insulation performance, etc.) of the circuit breaker sleeve workpieces. Summary of the Invention

[0005] The present application provides a circuit breaker shaft sleeve workpiece storage and retrieval rack, which can facilitate workers to place the circuit breaker shaft sleeve workpiece on the storage and retrieval rack and transport it by moving the storage and retrieval rack, while effectively ensuring the quality of the circuit breaker shaft sleeve workpiece during placement and transportation.

[0006] The present application provides a circuit breaker sleeve workpiece storage and retrieval rack, which adopts the following technical solution:

[0007] A circuit breaker sleeve workpiece storage and retrieval rack, comprising a rack body, at least three rotating wheels and a plurality of storage and retrieval units;

[0008] The interior of the frame has a cavity for arranging the plurality of access units, the cavity is opened at one side of the frame, and the rotating wheel is arranged at the bottom of the frame;

[0009] The storage and access unit includes a storage and access cabinet, a base plate, a pressure plate and a linkage assembly;

[0010] The storage cabinet is slidably connected to the frame, and a plurality of the storage cabinets are distributed in the cavity along a direction perpendicular to the sliding direction of the storage cabinets; the storage cabinet has a storage space for placing workpieces inside, and the storage space forms an opening at the top of the storage cabinet for the workpiece to enter and exit the storage space, and after the workpiece is placed in the storage space, its top is located above the storage space;

[0011] The bottom plate and the pressure plate are both elastic, the bottom plate is arranged inside the storage cabinet and located at the bottom of the storage space; the pressure plate is movably connected to the frame and is located above the storage cabinet, and the movement direction of the pressure plate is parallel to the distribution direction of the plurality of storage cabinets;

[0012] The linkage assembly is connected to the storage and access cabinet and the pressure plate at the same time. When the storage and access cabinet slides in a direction away from the frame, the linkage assembly drives the pressure plate to move in a direction away from the bottom plate. When the storage and access cabinet slides in a direction close to the frame to an extreme position, the pressure plate contacts and abuts against the top of the workpiece in the storage space.

[0013] By adopting the above technical solution, the workpiece can be placed in the storage space by pulling out the storage and retrieval cabinet, and the workpiece in the storage space can be stored in the cavity by pushing the storage and retrieval cabinet in. The workpiece in the storage space can maintain a relatively stable position in the storage space under the clamping positioning of the pressure plate and the bottom plate, thereby reducing the probability of the stored workpiece moving and vibrating during the movement of the storage and retrieval rack and causing it to be bumped and damaged. It can facilitate the staff to place the circuit breaker shaft sleeve workpiece on the storage and retrieval rack and transport it by moving the storage and retrieval rack, and at the same time can effectively ensure the quality of the circuit breaker shaft sleeve workpiece during the placement and transportation process.

[0014] Optionally, the access unit includes a plurality of positioning protrusions, and the positioning protrusions are used to be inserted into the inner space of the workpiece.

[0015] By adopting the above technical solution, it is convenient for workers to place and position the workpiece in the storage space and place it neatly, and at the same time it can effectively improve the position stability of the workpiece after placement.

[0016] Optionally, the plurality of positioning protrusions are distributed on the bottom plate at equal intervals and the positioning protrusions in adjacent rows are staggered, and after the positioning protrusions are inserted into the internal space of the workpiece, the spacing between adjacent workpieces is maintained.

[0017] By adopting the above technical solution, the capacity of the storage space for workpieces can be increased, the workpieces can be more reasonably distributed in the storage space, and the probability of collision and damage between adjacent workpieces during the placement of workpieces or the movement of storage and retrieval racks can be further reduced.

[0018] Optionally, the access unit further comprises a plurality of first elastic members, and the bottom plate is movably connected to the access cabinet along the movable direction of the pressure plate;

[0019] The two ends of the first elastic member are respectively connected to the bottom plate and the access cabinet, and have a tendency to drive the bottom plate to move upward to the limit position and maintain it, and the first elastic member is squeezed after the pressure plate applies pressure to the workpiece.

[0020] By adopting the above technical solution, the storage and retrieval unit can store workpieces of different axial sizes, and can further reduce the damage to the workpiece due to clamping and positioning while ensuring the position stability of the workpiece after storage. In addition, when the first elastic member drives the bottom plate to move upward to the extreme position after the storage and retrieval cabinet is pulled out, it can further facilitate the staff to access the workpiece.

[0021] Optionally, the positioning protrusion includes an expansion and contraction part and a fixing part;

[0022] The expansion and contraction member is elastic and has an air cavity therein; one end of the fixing member is fixedly connected to the bottom of the storage and access cabinet, and the other end of the fixing member seals the opening of the air cavity;

[0023] During the movement of the bottom plate relative to the storage and access cabinet, the expansion and contraction member is driven by the fixing member to expand and contract, and after expansion, the expansion and contraction member contacts and abuts against the inner wall of the workpiece.

[0024] By adopting the above technical solution, when the workpiece is clamped and positioned between the pressure plate and the base plate, the positioning effect of the positioning protrusion on the workpiece is also improved, thereby further reducing the probability of displacement and vibration of the workpiece during the movement of the storage and retrieval rack, thereby further ensuring the storage quality of the workpiece.

[0025] Optionally, it also includes a temperature control device and a humidity control device;

[0026] The temperature regulating device and the humidity regulating device are both arranged on the top of the frame, and both the temperature regulating device and the humidity regulating device are communicated with the cavity, and are respectively used to regulate the temperature and humidity in the cavity.

[0027] By adopting the above technical solution, a suitable environment can be provided for storing workpieces, thereby effectively reducing the probability that the workpieces will be affected by being stored in an unsuitable environment for a long time.

[0028] Optionally, the plurality of storage spaces are communicated with each other in the cavity, and the internal spaces of the plurality of workpieces are sealed between adjacent pressing plates and the bottom plate.

[0029] By adopting the above technical solution, the temperature and humidity control effects on the workpieces in the storage space can be effectively improved, and at the same time, the inner walls of the workpieces can be effectively protected to improve the reliability of subsequent use of the workpieces.

[0030] Optionally, a locking assembly is provided on a side of the storage cabinet away from the frame, and the locking assembly includes a locking member, a rotating member and a handle;

[0031] The rotating member is rotatably connected to the storage and access cabinet, the rotation axis of which is horizontal and perpendicular to the distribution direction of the plurality of storage and access units, and the rotation of the rotating member relative to the storage and access cabinet is limited;

[0032] The locking member is provided on the rotating member, and a locking groove for the locking member to engage with is provided on the frame; when the storage cabinet slides toward the frame to an extreme position, the rotating member rotates toward the frame to an extreme position, and the locking member engages with the locking groove to restrict the sliding of the storage cabinet; when the rotating member rotates toward the frame to an extreme position, the locking member leaves the locking groove to release the restriction on the sliding of the storage cabinet;

[0033] The handle is provided on the rotating member and is used to control the rotating member to rotate relative to the storage and access cabinet.

[0034] By adopting the above technical solution, it is convenient for staff to control the sliding of the storage and access cabinet, and at the same time it can effectively reduce the probability of the storage and access cabinet sliding out due to inertia or vibration during the movement of the storage and access rack after being pushed in.

[0035] Optionally, the locking assembly further includes a second elastic member;

[0036] The second elastic member is disposed between the rotating member and the storage cabinet, and has a tendency to drive the rotating member to rotate toward the frame body to a limit position and maintain the limit position.

[0037] By adopting the above technical solution, the relative position stability between the storage cabinet and the frame body after being pushed in can be further improved, thereby further improving the reliability of storing workpieces in the storage space.

[0038] Optionally, when the plurality of storage and access cabinets slide to their limit positions in a direction close to the frame and the plurality of rotating members rotate to their limit positions in a direction close to the frame, the plurality of storage and access cabinets and the plurality of rotating members together make the opening of the cavity have a certain sealing property.

[0039] By adopting the above technical solution, after the storage and retrieval cabinet is pushed in and locked into position, the impact of the external environment on the workpieces stored inside can be effectively reduced, and at the same time, the regulating effect of the temperature control device and the humidity control device on the workpiece storage environment can be further improved.

DETAILED DESCRIPTION

[0052] The following is combined with Figure 1-6 This application is described in further detail.

[0053] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a circuit breaker sleeve workpiece storage and retrieval rack, which is used in a circuit breaker sleeve production workshop for storing workpieces 6 during the circuit breaker sleeve processing process, and is convenient for staff to transport a large number of workpieces 6, so as to facilitate the transfer of workpieces 6 between different processing equipment.

[0054] Reference Figure 2 and Figure 3 The storage and retrieval rack comprises a frame 1, at least three rotating wheels 2, multiple access units 3, a temperature control device 4, and a humidity control device 5. The frame 1 serves as a carrier for other structures and also provides space for storing workpieces 6. The rotating wheels 2 allow the frame 1 to move on the ground, making it easier for staff to control the movement of the storage and retrieval rack. The access units 3 allow the storage and retrieval rack to store and retrieve workpieces 6. The temperature control device 4 and humidity control device 5 are used to adjust the temperature and humidity of the storage environment of the workpieces 6, respectively, to ensure the storage quality of the workpieces 6.

[0055] The frame 1 has an overall rectangular parallelepiped structure, with a rectangular parallelepiped cavity 11 formed therein. The cavity 11 extends through one side of the frame 1 to form an opening. In this embodiment, the length and width of the cavity 11 are preferably parallel to the length and width of the frame 1, respectively, and one side of the width of the cavity 11 extends through one side of the width of the frame 1 to form an opening.

[0056] The rotating wheels 2 are fixedly mounted on the bottom of the frame 1, and the rotating wheels 2 can rotate relative to the frame 1, thereby moving the frame 1 on the ground. In this embodiment, the storage and retrieval rack preferably includes four rotating wheels 2, which are respectively mounted at the four corners of the bottom of the frame 1. At this time, the frame 1 is in contact with the ground at the same time through the four rotating wheels 2, and the height direction of the frame 1 is vertical at this time; and the rotating wheels 2 are preferably universal wheels, which can automatically adjust their position according to the direction in which the staff controls the movement of the frame 1, so that the staff can control the movement of the frame 1; since universal wheels are common existing technologies, they will not be described in detail here, and they are only briefly shown in the accompanying drawings; in other embodiments, a handle 362 can be extended outward from the top of the frame 1 to facilitate the staff to control the movement of the storage and retrieval rack.

[0057] Reference Figure 3 and Figure 4 The access unit 3 is installed on the frame 1 , and the cavity 11 provides space for installing multiple access units 3 , and the multiple access units 3 are evenly spaced on the frame 1 along the height direction of the frame 1 .

[0058] Reference Figure 1 and Figure 4The access unit 3 includes a storage cabinet 31, a base plate 32, a pressure plate 33, a linkage assembly 34, a plurality of positioning protrusions 35, and a locking assembly 36. The storage cabinet 31 is used to place workpieces 6; the base plate 32 and the pressure plate 33, through the linkage assembly 34, position the workpieces 6 placed on the storage cabinet 31; the positioning protrusions 35 further position the workpieces 6 placed on the storage cabinet 31, making it easier for workers to store and retrieve the workpieces 6; and the locking assembly 36 is used to improve the positional stability of the storage cabinet 31 on the frame 1, thereby improving the positional stability of the workpieces 6 placed on the storage cabinet 31.

[0059] The storage cabinet 31 is generally rectangular in shape, and includes a storage space 311 for placing the workpiece 6 therein. In this embodiment, preferably, one side of the storage space 311 extends through the height of the storage cabinet 31 to form an opening, and preferably, the length and width of the storage space 311 are parallel to the length and width of the storage cabinet 31, respectively.

[0060] The storage cabinet 31 is slidably connected to the frame 1, with its sliding direction parallel to its own width and to the width of the frame 1. Furthermore, the storage cabinet 31 can enter and exit the cavity 11 through the opening of the cavity 11 during its sliding relative to the frame 1. In this embodiment, the storage cabinet 31 is preferably slidably connected to the frame 1 via pulleys and tracks (e.g., a drawer). Furthermore, the storage cabinet 31 preferably remains connected to the frame 1 when it slides away from the frame 1 to its extreme position, thereby reducing the probability of the storage cabinet 31 falling due to excessive sliding. Since the aforementioned sliding connection method is common in the prior art, it will not be described in detail here, and is only briefly illustrated in the accompanying drawings.

[0061] When the access cabinet 31 slides to the extreme position toward the frame 1, the side of the access cabinet 31 away from the frame 1 will be flush with the end face of the side of the frame 1 close to the opening of the cavity 11; when the access cabinet 31 slides to the extreme position toward the direction away from the frame 1, the staff can easily place the workpiece 6 on the access cabinet 31.

[0062] The bottom plate 32 and the pressing plate 33 are both rectangular plate structures and have a certain degree of elasticity.

[0063] The size of the bottom plate 32 is adapted to the size of the storage space 311, that is, the length and width of the bottom plate 32 are respectively equal to the length and width of the storage space 311, and the bottom plate 32 is installed near the bottom of the storage space 311 in a position in which the thickness direction of the bottom plate 32 is parallel to the height direction of the storage space 311; the bottom plate 32 can move relative to the storage cabinet 31 in its own thickness direction in the storage space 311, and a plurality of first elastic members 37 are installed between the bottom plate 32 and the inner wall of the bottom of the storage space 311. The two ends of the first elastic members 37 are respectively fixedly connected to the bottom plate 32 and the storage cabinet 31, and have a tendency to drive the bottom plate 32 to move upward to the extreme position and maintain it, and at this time the bottom plate 32 is still located near the bottom of the storage space 311; when the bottom plate 32 overcomes the force of the first elastic members 37 and moves downward to the extreme position, the top of the workpiece 6 placed on the bottom plate 32 will be located above the storage space 311. In this embodiment, the first elastic member 37 is preferably a spring, and the workpiece 6 is preferably placed on the bottom plate 32 in a position in which the axial direction is parallel to the thickness direction of the bottom plate 32 .

[0064] The pressure plate 33 is movably mounted on the frame 1 and is located in the cavity 11. It is located above the corresponding bottom plate 32 and above the corresponding storage and access cabinet 31, and its movable direction is parallel to the height direction of the storage and access cabinet 31. In this embodiment, the length and width directions of the pressure plate 33 are preferably parallel to the length and width directions of the bottom plate 32, respectively.

[0065] The pressure plate 33 is used to contact and abut the top of the workpiece 6 placed on the base plate 32, and the pressure plate 33 and the corresponding access cabinet 31 are linked through the linkage component 34, so that when the access cabinet 31 slides to the extreme position in the direction close to the frame 1, the pressure plate 33 moves downward to the extreme position relative to the frame 1; when the access cabinet 31 slides to the extreme position in the direction away from the frame 1, the pressure plate 33 moves upward to the extreme position relative to the frame 1; and the pressure plate 33 remains above the corresponding access cabinet 31 during the movement relative to the frame 1.

[0066] Reference Figure 4 and Figure 5 The linkage assembly 34 includes a first rack 341 , a second rack 342 , a first gear 343 , a second gear 344 and a synchronous belt 345 .

[0067] The first rack 341 is fixedly installed on one side of the length direction of the access cabinet 31 along the width direction of the access cabinet 31; the second rack 342 is fixedly installed on one side of the length direction of the pressure plate 33 along the thickness direction of the pressure plate 33 and extends along the thickness direction of the pressure plate 33; the first gear 343 and the second gear 344 are both rotatably installed on the position of the frame 1 on one side of the length direction in the cavity 11, the second gear 344 is located above the first gear 343 and is aligned with the second gear 344 along the height direction of the frame 1, the rotation axes of the first gear 343 and the second gear 344 are both parallel to the length direction of the frame 1, the first gear 343 is meshed with the first rack 341 and the second gear 344 is meshed with the second rack 342; the synchronous belt 345 is simultaneously wound around the first gear 343 and the second gear 344, so that the first gear 343 and the second gear 344 rotate synchronously and in the same direction relative to the frame 1. In this embodiment, the storage cabinet 31 and the pressure plate 33 are preferably linked by two linkage assemblies 34, and the two linkage assemblies 34 are symmetrically located on either side of the length of the storage cabinet 31. In this embodiment, the pressure plate 33 preferably has a tendency to move upward to and maintain its limit position (e.g., via a tension spring). When the storage cabinet 31 slides away from the frame 1 to its limit position, the first rack 341 and the first gear 343 disengage. As the storage cabinet 31 slides toward the frame 1, the first rack 341 and the first gear 343 reengage. During the movement of the pressure plate 33, the second rack 342 and the second gear 344 remain engaged.

[0068] Reference Figure 1 and Figure 4 The positioning protrusion 35 includes an expansion member 351 and a fixing member 352. The expansion member 351 is fixedly mounted on the bottom plate 32, and the fixing member 352 is fixedly mounted on the bottom of the storage cabinet 31. The expansion member 351 is used to position the workpiece 6 after it is placed on the bottom plate 32; and the fixing member 352 is used to drive the expansion member 351 to expand and contract, thereby facilitating the expansion member 351 to position and release the workpiece 6.

[0069] The expansion and contraction member 351 is generally spherical in structure, is elastic, and has an internal air cavity 3511. Expansion and contraction are achieved by changes in the volume of the air cavity 3511. The expansion and contraction member 351 is fixedly mounted on the top of the base plate 32, and an opening is correspondingly provided on the base plate 32, connecting the air cavity 3511 with the space below the base plate 32. Multiple expansion and contraction members 351 are evenly spaced on the top of the base plate 32, and adjacent rows of expansion and contraction members 351 are staggered. In this embodiment, the spacing between adjacent expansion and contraction members 351 is preferably such that when each adjacent expansion and contraction member 351 has a corresponding workpiece 6 positioned therein, the adjacent workpieces 6 maintain a certain spacing.

[0070] One end of the fixing member 352 is fixedly connected to the inner wall at the bottom of the storage space 311, and the other end extends upward in a direction parallel to the movement direction of the bottom plate 32, and passes through the bottom plate 32 to seal the opening of the air cavity 3511 of the corresponding expansion and contraction member 351; during the movement of the bottom plate 32 relative to the storage and access cabinet 31, the top of the fixing member 352 keeps the opening of the air cavity 3511 sealed.

[0071] When the base plate 32 moves downward to its limit position, the expansion member 351 expands to its maximum, and the radial dimension of the expansion member 351 is now larger than the inner diameter of the workpiece 6 with the largest inner diameter. When the base plate 32 moves upward to its limit position, the expansion member 351 contracts to its minimum, and the radial dimension of the expansion member 351 is now smaller than the inner diameter of the workpiece 6 with the smallest inner diameter. This allows the positioning protrusion 35 to accommodate workpieces 6 of different inner diameters, thereby enabling the storage and retrieval unit 3 to accommodate workpieces 6 of different sizes.

[0072] Reference Figure 2 and Figure 4 When the access cabinet 31 slides to the extreme position in the direction away from the frame 1, the staff can place multiple workpieces 6 on the bottom plate 32 according to the positions of the multiple positioning protrusions 35. At this time, the gravity of the workpieces 6 can drive the bottom plate 32 to overcome the force of the multiple first elastic members 37 and move downward, so that the multiple expansion and contraction members 351 expand slightly, but at this time the expansion and contraction members 351 cannot completely fit and resist the inner wall of the workpiece 6; afterwards, when the access cabinet 31 slides to the extreme position in the direction close to the frame 1, the corresponding pressure plate 33 will move downward relative to the frame 1 until it contacts and resists the tops of the multiple workpieces 6. At this time, as the access cabinet 31 continues to slide, the pressure plate 33 will apply downward pressure to multiple workpieces 6, thereby driving the corresponding bottom plates 32 to continue to move downward until the storage and retrieval cabinet 31 slides into place, and during this process, the expansion and contraction parts 351 will be able to expand to completely fit against the inner wall of the workpiece 6, so that the workpiece 6 is clamped and positioned by the pressure plate 33 and the bottom plate 32 above and below, and the radial displacement and vibration are limited by the expanded expansion and contraction parts 351, so as to ensure the position stability of the workpiece 6 stored in the cavity 11; and, at this time, the top opening of the internal space of the workpiece 6 is sealed by the pressure plate 33, and the bottom opening is sealed by the expansion and contraction parts 351, which can effectively reduce the probability of impurities entering the internal space of the workpiece 6 and affecting it during the storage of the workpiece 6.

[0073] Reference Figure 3 and Figure 4The temperature control device 4 and the humidity control device 5 are both fixedly mounted on the top of the frame 1. The temperature control device 4 is used to control the temperature of the air in the cavity 11, while the humidity control device 5 is used to control the humidity of the air in the cavity 11, thereby making the temperature and humidity of the air in the cavity 11 more suitable for the long-term storage of the workpiece 6. In this embodiment, since the temperature control device 4 and the humidity control device 5 having the above-mentioned functions are both common existing technologies, they will not be described in detail here, and they are only briefly shown in the drawings.

[0074] When the storage cabinet 31 slides to its limit position toward the frame 1, a gap exists between the storage cabinet 31 and the inner wall of the cavity 11, which is away from the opening. At this point, the temperature control device 4 and the humidity control device 5 can both regulate the temperature and humidity of the environment in which the workpiece 6 is stored by adjusting the temperature and humidity of the air in the cavity 11.

[0075] Reference Figure 2 and Figure 4 The locking assembly 36 is installed on the side of the access cabinet 31 away from the frame 1 and is located at the top of the access cabinet 31. It is used to fix the relative position between the access cabinet 31 and the frame 1, and includes a rotating member 361, a locking member 364, a handle 362 and a second elastic member 363.

[0076] The rotating member 361 is a rectangular plate-shaped structure as a whole, and one end of the rotating member 361 is rotatably connected to the top of the other end of the storage and access cabinet 31 in the width direction. The rotating axis is parallel to its own length direction and the length direction of the storage and access cabinet 31.

[0077] The rotating member 361 is restricted in its rotation relative to the storage cabinet 31 .

[0078] When the rotating member 361 rotates upward to its limit position, the width of the rotating member 361 is parallel to the height of the storage and access cabinet 31, and the end of the rotating member 361 away from the corresponding storage and access cabinet 31 is close to the bottom of the storage and access cabinet 31 above it. In this embodiment, preferably, a sealing strip is fixedly installed on the side of the rotating member 361 away from the corresponding storage and access cabinet 31; when the storage and access cabinet 31 slides toward the frame 1 to its limit position and the rotating member 361 rotates upward to its limit position, the rotating member 361 will contact and abut the storage and access cabinet 31 above it through the sealing strip, thereby improving the sealing performance; when multiple storage and access cabinets 31 all slide toward the frame 1 to their limit positions and the rotating member 361 rotates upward to their limit positions, the opening of the cavity 11 will have a certain degree of sealing performance, thereby improving the temperature and humidity control effect of the temperature control device 4 and the humidity control device 5 on the storage environment of the workpiece 6.

[0079] When the rotating member 361 rotates downward to the limit position, the width direction of the rotating member 361 is parallel to the width direction of the access cabinet 31, and most of the rotating member 361 will be located on the side of the corresponding access cabinet 31 away from the frame 1.

[0080] The handle 362 is fixedly installed on the side of the rotating member 361 away from the corresponding storage and access cabinet 31, which is used to facilitate the staff to control the rotation of the rotating member 361 relative to the storage and access cabinet 31, and at the same time facilitate the staff to apply force to control the storage and access cabinet 31 to slide relative to the frame 1; when the rotating member 361 rotates downward to the extreme position, the handle 362 is located at the bottom of the rotating member 361.

[0081] The second elastic member 363 is mounted at the pivotal connection between the rotating member 361 and the access cabinet 31. Its ends are fixedly connected to the rotating member 361 and the access cabinet 31, respectively. The second elastic member 363 has the tendency to drive the rotating member 361 to rotate upward relative to the access cabinet 31 to its limit position and maintain that position. In this embodiment, the second elastic member 363 is preferably a torsion spring. Since torsion springs are common in the art, their detailed description is omitted here. The figures only illustrate their mounting location and omit their structure.

[0082] Reference Figure 2 and Figure 6 The locking member 364 is fixedly installed on the rotating member 361 near the storage cabinet 31 and is located at one end of the length direction of the rotating member 361. A locking groove 12 is correspondingly opened on the frame 1 for the locking member 364 to enter and form a snap connection, and the locking groove 12 is formed with an opening for the locking member 364 to enter and exit on the side of the frame 1 near the opening of the cavity 11.

[0083] When the rotating member 361 is rotated downward to its limit relative to the storage cabinet 31, the locking member 364 is in a position where it can freely enter and exit the locking groove 12. When the storage cabinet 31 slides toward the frame 1 to its limit, the rotating member 361 is controlled to rotate upward to its limit relative to the storage cabinet 31, which drives the locking member 364 into the locking groove 12 and forms a snap fit with the frame 1 to restrict the storage cabinet 31 from sliding relative to the frame 1. In this embodiment, since the locking member 364 with the above-mentioned functions is common in the prior art, it will not be described in detail here, and it will only be briefly illustrated in the drawings.

[0084] The implementation principle of a circuit breaker sleeve workpiece storage and retrieval rack in the embodiment of the present application is as follows:

[0085] When a certain amount of workpieces 6 need to be stored on the access rack, the handle 362 is used to control the rotating member 361 to move downward to the limit position, and then the access cabinet 31 is slid away from the rack body 1. Then, the workpiece 6 is placed on the bottom plate 32 through the multiple positioning protrusions 35, so that the expansion and contraction member 351 enters the interior of each workpiece 6. After the workpiece 6 is placed, the handle 362 is also used to control the rotating member 361 to move downward to the limit position, and then the access cabinet 31 is controlled to slide towards the rack body 1 to the limit position. Then, the handle 362 is released, and the rotating member 361 can be rotated upward to the limit position under the action of the second elastic member 363, so that the locking member 364 is engaged in the locking groove 12, so that the relative position of the access cabinet 31 relative to the rack body 1 is fixed, which is convenient for the staff to control the movement of the access rack through the multiple rotating wheels 2 later.

[0086] When the access cabinet 31 is controlled to slide toward the rack body 1 to its limit position, the access cabinet 31 drives the corresponding pressure plate 33 to move downward through the linkage assembly 34, so as to contact and abut against the tops of the multiple workpieces 6 and apply downward pressure to the workpieces 6, causing the bottom plate 32 to overcome the force of the multiple first elastic members 37 and move downward, thereby causing the multiple expansion and contraction members 351 to expand and further position the workpieces 6. At this time, the workpieces 6 will be clamped and positioned between the pressure plate 33 and the bottom plate 32, thereby improving the position stability of the workpieces 6 during the subsequent movement of the access cabinet and reducing the probability of the workpieces 6 being damaged by collision.

[0087] When the workpiece 6 is stored on the storage rack for a long time, the staff can control the temperature control device 4 and the humidity control device 5 according to the type of the workpiece 6, so that the workpiece 6 can be stored in a suitable environment to ensure the quality of the workpiece 6.

[0088] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
