Description

Technical Field

[0001] This invention relates to the field of locking and assisted extraction technology, and more specifically to an integrated assisted extraction device with locking and assisted extraction functions that can be quickly tightened. Background Technology

[0002] In the field of equipment plug-in installation and maintenance, plug-in blades, as core connecting components, require specialized auxiliary tools for fastening and pull-out. Existing technologies primarily employ two methods for fixing plug-in blades: one involves separate operation of the pull-out aid and screws, requiring manual manipulation of the pull-out aid for positioning, followed by screwdriver installation and removal of the screws for tightening—a cumbersome process requiring frequent tool switching; the other uses hand-tightening screws to partially assist in pull-out, but the screw heads are typically small, making manual tightening inconvenient, and requiring a screwdriver for complete tightening, thus failing to achieve true tool-free operation. Furthermore, both methods suffer from fragmented functions and low operational efficiency, and traditional structures lack a stable locking mechanism, making them susceptible to screw loosening due to vibration or other external forces, affecting the reliability of the connection between the plug-in blade and the equipment beam, and failing to meet the requirements for convenient plug-in installation and stable fastening.

[0003] Existing technologies suffer from technical problems such as inconvenient insertion blade fixing operations requiring tool assistance, low fastening efficiency, and insufficient locking stability due to the dispersion of functions. Summary of the Invention

[0004] This application provides an integrated locking and pulling aid that can quickly tighten, which is intended to address the technical problems in the prior art where the fixing of insert blades is inconvenient and requires tool assistance, and where the dispersed functions lead to low tightening efficiency and insufficient locking stability.

[0005] In view of the above problems, this application provides an integrated extraction aid with locking function that can be quickly tightened.

[0006] The first aspect of this application provides an integrated extraction aid with a locking function that can be quickly tightened, the extraction aid comprising: A pull ring assembly; a rotating shaft assembly, the first end of which is hinged to the pull ring assembly; an insert blade, the insert blade being hinged to the second end of the rotating shaft assembly; wherein the pull ring assembly moves relative to the insert blade between an unlocked position and a locked position, and when in the locked position, the pull ring assembly and the insert blade form an elastic limiting lock to restrict the rotation of the rotating shaft assembly.

[0007] A second aspect of this application provides an electronic device comprising a crossbeam and an integrated puller with a locking and pull-out function, as described in the first aspect, for performing a first locking operation and a second unlocking operation, wherein the second unlocking operation is the reverse of the first locking operation; wherein, in the first locking operation, the puller is used to fasten and lock the insert blade to the crossbeam, comprising: aligning the rotating shaft assembly to the screw hole of the crossbeam, rotating a preset lead to press the insert blade to the crossbeam, rotating the horizontal pull ring assembly 90° to press it into the limiting protrusion position, and locking the puller in a locked state according to the first locking operation; wherein, the locked state comprises: the plunger pin elastically engaging the S-shaped protrusion, the limiting step and the plane being locked, maintaining the limiting and locking of the pull ring assembly, and the locking screw being unable to rotate.

[0008] One or more technical solutions provided in this application have at least the following technical effects or advantages: A pull ring assembly; a rotating shaft assembly, the first end of which is hinged to the pull ring assembly; and an insert blade, the insert blade being hinged to the second end of the rotating shaft assembly. The pull ring assembly moves relative to the insert blade between an unlocked position and a locked position. When in the locked position, the pull ring assembly and the insert blade form an elastic limiting lock to restrict the rotation of the rotating shaft assembly. This achieves the integration of pull-out assistance and locking functions, limiting the rotation of the rotating shaft assembly through the elastic limiting lock of the pull ring assembly and the insert blade, thus achieving the technical effect of rapid fastening and stable locking of the insert blade.

Detailed Implementation

[0019] This application provides an integrated locking and pulling aid that can quickly tighten, in order to address the technical problems in the prior art where the fixing of insert blades is inconvenient and requires tool assistance, and where the dispersed functions lead to low tightening efficiency and insufficient locking stability.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, this application provides an integrated extraction aid with a locking function that can be quickly tightened, the extraction aid comprising: Pull ring assembly 1.

[0022] The first end of the rotating shaft assembly 2 is hinged to the pull ring assembly 1.

[0023] Insert blade 3, which is hinged to the second end of the rotating shaft assembly 2.

[0024] The pull ring assembly 1 moves between an unlocked position and a locked position relative to the insert blade 3. When in the locked position, the pull ring assembly 1 and the insert blade 3 form an elastic limiting lock to restrict the rotation of the shaft assembly 2.

[0025] Specifically, the pull ring assembly 1 is a ring structure, consisting of a pull ring, a plunger pin (i.e., an elastic limiting element), and a fixing screw. One side of the pull ring has a mounting screw hole 1013, and the other side has a lifting step 1011 for unlocking operation. A notch is made in the middle and a plunger pin mounting hole 1012 is machined, while a chamfered limiting step 1014 is formed. During assembly, the plunger pin is inserted into the mounting hole, and then the fixing screw is passed through the mounting screw hole 1013, so that the pull ring assembly 1 and the first end of the rotating shaft assembly 2 form a hinge structure.

[0026] The rotating shaft assembly 2 serves as the connecting core, with its first end hinged to the pull ring assembly 1 and its second end hinged to the insert blade 3. The assembly includes a rotating shaft, a locking screw 202, and a limiting screw 203. The rotating shaft has a block structure, with a locking screw mating hole 2012 machined on one side and fixing screw mating holes 2011 on both sides. The other side has a limiting screw fixing hole 2013 machined on it. The locking screw 202 has a machined rod structure, with a multi-threaded thread 2021 at one end to allow for tightening / loosening by no more than two rotations. It has a boss 2023 in the middle and a square notch-shaped limiting step 2022 at the other end. During assembly, the locking screw 202 passes through the mating hole of the rotating shaft and is engaged with the square notch-shaped limiting step 2022 by the limiting screw 203, thus achieving circumferential anti-rotation and axial limiting of the rotating shaft and the locking screw 202. At the same time, the boss 2023 and the insert blade 3 provide thrust resistance.

[0027] The insert blade 3 is the functional execution end, and it has a through hole 301 for the shaft assembly 2 to pass through. It has a double-layer circular stepped surface structure, with the larger step closer to the shaft assembly 2. The panel has a symmetrical limiting protrusion 302 that cooperates with the pull ring assembly 1. The side of the protrusion is machined with an S-shaped protrusion 3021, and the lower part has a plane 3022 that is adapted to the pull ring limiting step 1014. During assembly, the second end of the shaft assembly 2 passes through the through hole 301 of the insert blade 3 to form a hinge relationship.

[0028] In terms of functional cooperation, the pull ring assembly 1 can move between the unlocked position and the locked position relative to the insert blade 3: when switched to the locked position, the plunger pin of the pull ring assembly 1 slides into and locks along the S-shaped protrusion 3021 of the limiting protrusion 302 of the insert blade 3 by means of elasticity, and at the same time, the limiting step 1014 of the pull ring is tightly engaged with the plane 3022 of the lower part of the protrusion of the insert blade 3. The double cooperation forms an elastic limiting lock. This locked state can restrict the rotation of the shaft assembly 2, thereby preventing the locking screw 202 from rotating and ensuring that the puller remains tight; when it is necessary to unlock, by moving the lifting step 1011 of the pull ring assembly 1, the plunger pin is disengaged from the S-shaped protrusion 3021 and the limiting step 1014 is separated from the plane 3022, so that the lock can be released and the rotation ability of the shaft assembly 2 can be restored.

[0029] Furthermore, the pull ring assembly 1 includes: A pull ring, the pull ring having an annular structure; at least one plunger pin, the plunger pin being an elastic limiting element, disposed on the pull ring.

[0030] Specifically, the pull ring has an overall ring structure, and its structural design revolves around ease of operation and reliable limiting. A mounting screw hole 1013 is provided on one side for forming a hinge structure with the rotating shaft assembly 2 through a fixing screw, providing a basis for the rotation of the pull ring relative to the rotating shaft assembly 2. A lifting step 1011 is machined on the other side. This step is the key force-bearing part for unlocking operation, making it easy for the operator to release the lock by moving the step. A notch is provided in the middle of the pull ring, and at least one plunger pin mounting hole 1012 is machined at the notch. At the same time, a limiting step 1014 with a chamfer is formed at the corresponding position of the notch. The limiting step 1014 is used to cooperate with the insert blade 3 to achieve auxiliary anti-rotation. The plunger pin is an elastic limiting component. During assembly, it needs to be inserted into the plunger pin mounting hole 1012 of the pull ring. Its core function is that when the pull ring is switched to the locked position, it slides into and locks itself along the S-shaped protrusion 3021 of the limiting protrusion 302 of the insert blade 3 based on its own elasticity. Together with the limiting step 1014 of the pull ring, it forms a double limiting structure, thereby limiting the rotation of the rotating shaft assembly 2, ensuring that the puller remains in a tight state, and preventing the locking screw 202 from loosening.

[0031] Furthermore, the pull ring has a mounting screw hole 1013 on one side and a lifting step 1011 on the other side, with a notch in the middle and a plunger pin mounting hole 1012 machined therein, while forming a chamfered limiting step 1014; wherein, the mounting screw hole 1013 is used to hinge with the rotating shaft assembly 2, the lifting step 1011 is used to unlock, and the limiting step 1014 is used to limit and prevent rotation with the insert blade 3.

[0032] Specifically, a mounting screw hole 1013 is provided on one side of the pull ring. This mounting screw hole 1013 is used to form a hinge structure with the rotating shaft assembly 2 through a fixing screw, providing an assembly basis for the rotation of the pull ring relative to the rotating shaft assembly 2. A lifting step 1011 is machined on the other side. This lifting step 1011 is a key force-bearing part in the unlocking process. The operator can lift the step to release the pull ring assembly 1 from the locked state with the insert blade 3 and realize the unlocking operation. A notch is provided in the middle of the pull ring. A plunger pin mounting hole 1012 is machined at the notch to install the plunger pin as an elastic limiting member. At the same time, a chamfered limiting step 1014 is formed around the notch. When the pull ring assembly 1 is in the locked position, the limiting step 1014 can tightly engage with the corresponding plane 3022 on the insert blade 3. Together with the elastic clamping effect of the plunger pin, it can limit the rotation of the insert blade 3 and thus restrict the rotation of the rotating shaft assembly 2, ensuring the tightness of the puller.

[0033] Furthermore, the assembly method of the pull ring assembly 1 includes: inserting the plunger pin into the plunger pin mounting hole 1012, and screwing the fixing screw into the mounting screw hole 1013 to form a hinge structure between the pull ring assembly 1 and the rotating shaft assembly 2.

[0034] Specifically, a mounting screw hole 1013 is provided on one side of the pull ring. This screw hole cooperates with a fixing screw to hinge the pull ring to the rotating shaft assembly 2, providing assembly support for the rotation of the pull ring relative to the rotating shaft assembly 2. A lifting step 1011 is machined on the other side. This step is the key force point for unlocking. By moving the lifting step 1011, the operator can drive the pull ring out of the locked state with the insert blade 3, thereby unlocking it. A notch is provided in the middle of the pull ring. A plunger pin mounting hole 1012 is machined at the notch for installing a plunger pin as an elastic limiting member. At the same time, a chamfered limiting step 1014 is formed at the corresponding position of the notch. When the pull ring is in the locked position, the limiting step 1014 can engage with the corresponding plane 3022 on the insert blade 3, assisting the plunger pin in limiting and preventing the insert blade 3 from rotating, thereby restricting the rotation of the rotating shaft assembly 2 and ensuring the fastening effect of the puller.

[0035] Furthermore, the rotating shaft assembly 2 includes: The rotating shaft 201 has a locking screw mating hole 2012 machined on its first surface, and through fixing screw mating holes 2011 machined on both sides. The second surface has a limiting screw fixing hole 2013 machined. The rotating shaft 201 is hinged to the pull ring assembly 1.

[0036] The locking screw 202 is a machined rod structure and is operably connected to the rotating shaft 201. The locking screw 202 is provided with an external thread, which is a multi-start thread 2021.

[0037] An anti-rotation structure is provided between the rotating shaft 201 and the locking screw 202, so that the rotation of the rotating shaft 201 can drive the locking screw 202 to rotate synchronously.

[0038] Specifically, the rotating shaft 201 has a block structure, and its multiple sides are machined with functional matching holes to meet assembly and transmission requirements: the first side is machined with a locking screw mating hole 2012 for inserting the locking screw 202 to achieve the initial assembly of the two; both sides are machined with through fixing screw mating holes 2011, which can form a hinge with the pull ring assembly 1 through the fixing screw, providing a basis for the rotation of the pull ring assembly 1 relative to the rotating shaft 201; the second side is machined with a limit screw fixing hole 2013 for installing the limit screw 203 to construct an anti-rotation structure.

[0039] The locking screw 202 is a machined rod structure that is operably connected to the locking screw mating hole 2012 of the rotating shaft 201. The rod body is provided with an external thread, which is a multi-start thread 2021. The multi-start thread 2021 can be double-start or triple-start. The goal is to achieve a lead of about 5mm in no more than two rotations to meet the needs of quick tightening or loosening. At the same time, one end of the locking screw 202 is provided with a square notch-shaped limiting step 2022, and the middle is provided with a boss 2023.

[0040] To achieve synchronous rotation of the rotating shaft 201 driving the locking screw 202, an anti-rotation structure is provided between them. This structure consists of a square notch-shaped limiting step 2022 at one end of the locking screw 202 and a limiting screw 203 installed in the limiting screw fixing hole 2013 on the second side of the rotating shaft 201. During assembly, after the locking screw 202 is inserted into the locking screw mating hole 2012 of the rotating shaft 201, the square notch-shaped limiting step 2022 of the locking screw 202 is aligned with the rotating shaft. The limiting screw is fixed in the fixing hole 2013 of 201, and then the limiting screw 203 is screwed into the fixing hole and locked into the square notch-shaped limiting step 2022. This not only achieves circumferential anti-rotation of the rotating shaft 201 and the locking screw 202, restricting their relative rotation, but also achieves axial thrust through the contact between the boss 2023 in the middle of the locking screw 202 and the insert blade 3. Finally, the effect of the rotating shaft 201 driving the locking screw 202 to rotate synchronously is achieved, ensuring the stable transmission of the thread tightening or loosening action.

[0041] Furthermore, the anti-rotation structure includes: A limiting step 2022 is provided at one end of the locking screw 202, and a boss 2023 is provided in the middle. The limiting step 2022 is in the shape of a square notch, and the boss 2023 is used for limiting.

[0042] A limiting screw 203 is disposed on the rotating shaft 201 and cooperates with the limiting step 2022.

[0043] The limiting screw 203 is engaged with the limiting step 2022 to perform circumferential anti-rotation and axial limiting between the rotating shaft 201 and the locking screw 202, and to perform thrust resistance between the boss 2023 and the insert blade 3.

[0044] Specifically, the locking screw 202, as the core transmission component of the rotating shaft assembly 2, has a square notch-shaped limiting step 2022 machined at one end and a boss 2023 integrally formed in the middle. The square notch-shaped limiting step 2022 is used to form a matching engagement with the limiting screw 203 on the rotating shaft 201, while the middle boss 2023 undertakes the limiting function and provides thrust support for subsequent assembly with the insert blade 3.

[0045] The rotating shaft 201 has a limiting screw fixing hole 2013 machined at the assembly position corresponding to the locking screw 202 for installing the limiting screw 203. The limiting screw 203 is installed in the fixing hole, and its end can extend to the mating area between the rotating shaft 201 and the locking screw 202, forming a precise fit with the square notch-shaped limiting step 2022 of the locking screw 202.

[0046] In terms of assembly and functional implementation, after the locking screw 202 is inserted into the locking screw engagement hole 2012 of the rotating shaft 201, the positions of the two are adjusted so that the square notch-shaped limiting step 2022 of the locking screw 202 is aligned with the limiting screw fixing hole 2013 of the rotating shaft 201. Then, the limiting screw 203 is screwed into the fixing hole until the end of the limiting screw 203 is engaged in the square notch-shaped limiting step 2022 of the locking screw 202. This engaging structure can limit the circumferential phase between the rotating shaft 201 and the locking screw 202. The rotation of the shaft 201 directly drives the locking screw 202 to rotate synchronously, ensuring the stable transmission of the thread tightening or loosening action. On the other hand, it can achieve axial limiting of both, preventing the locking screw 202 from being displaced in the axial direction. At the same time, the contact between the boss 2023 in the middle of the locking screw 202 and the insert blade 3 can further form an axial thrust, avoiding the loosening of the locking screw 202 due to axial force during transmission, and ensuring the structural stability and transmission reliability of the entire shaft assembly 2.

[0047] Furthermore, the multi-start thread 2021 is configured with a preset lead, which is such that the insertion blade 3 can be tightened or loosened within a range of no more than two rotations.

[0048] Specifically, the locking screw 202, as a key transmission component of the rotating shaft assembly 2, has a multi-start thread 2021 on its shaft body. This multi-start thread 2021 is equipped with a preset lead to meet the needs of quickly tightening or loosening the insert blade 3. The design standard of this preset lead is that when the operator rotates the locking screw 202, within a range of no more than two rotations, the multi-start thread 2021 can drive the insert blade 3 to achieve tight engagement or separation from the crossbeam 4. This multi-start thread 2021 can be set to double-start or triple-start, and its lead target is to achieve an axial movement of about 5mm within two rotations, thereby significantly shortening the operation time. Compared with the traditional single-start thread that requires multiple rotations to complete the tightening / loosening, this significantly improves the operating efficiency of the puller and ensures the connection stability of the insert blade 3 after tightening.

[0049] Furthermore, the insert blade 3 includes: A limiting protrusion 302 is provided to cooperate with the plunger pin. The limiting protrusion 302 has a symmetrical structure, with an S-shaped protrusion 3021 on the side and a plane 3022 on the bottom to cooperate with the limiting step 1014.

[0050] A through hole 301 is provided for the shaft assembly 2 to pass through. The through hole 301 has a double-layer circular stepped surface structure, and the larger step is located on the side closer to the shaft assembly 2.

[0051] Specifically, the insert blade 3, as the functional execution component of the puller, is structurally designed around its limiting fit with the pull ring assembly 1 and its assembly adaptation with the rotating shaft assembly 2. Its specific structure and function are as follows: The insert blade 3 has a limiting protrusion 302 on its panel that engages with the plunger pin in the pull ring assembly 1. This limiting protrusion 302 adopts a symmetrical design, with an S-shaped protrusion 3021 machined on its side and a plane 3022 on its lower part that matches the chamfered limiting step 1014 in the pull ring assembly 1. The S-shaped protrusion 3021 provides a sliding path and locking space for the plunger pin. When the pull ring assembly 1 moves towards the locked position, the plunger pin can slide along the S-shaped protrusion 3021 and lock itself due to its elasticity. Simultaneously, the limiting step 1014 of the pull ring and the plane 3022 on the lower part of the limiting protrusion 302 are tightly engaged, forming a double limiting mechanism to ensure the stability of the locked state of the pull ring assembly 1, thereby restricting the rotation of the rotating shaft assembly 2.

[0052] In addition, the insert blade 3 is provided with a through hole 301 for inserting the rotating shaft assembly 2. The through hole 301 has a double-layer circular stepped surface structure, and the larger step is located on the side closer to the rotating shaft assembly 2. This stepped surface design can be adapted to the boss 2023 of the locking screw 202 in the rotating shaft assembly 2. When the rotating shaft assembly 2 is assembled, after the locking screw 202 penetrates the through hole 301, its boss 2023 can contact the stepped surface of the through hole 301 to achieve axial thrust, avoid axial displacement of the rotating shaft assembly 2 during transmission, and ensure the stability and transmission reliability of the entire puller assembly structure.

[0053] Furthermore, the insert blade 3 includes: When the pull ring assembly 1 is in the locked position, the plunger pin slides along the S-shaped protrusion 3021 into the limiting protrusion 302 and locks in place, performing anti-rotation locking.

[0054] The limiting step 1014 engages with the plane 3022 to assist in preventing rotation.

[0055] Specifically, when the pull ring assembly 1 moves to the locked position, it and the insert blade 3 cooperate through a double structure to achieve stable anti-rotation locking. The specific process is as follows: the plunger pin on the pull ring assembly 1 will slide along the S-shaped protrusion 3021 on the side of the limiting protrusion 302 of the insert blade 3, and finally slide into the protrusion and rely on its own elasticity to lock. This locking structure can directly restrict the rotation of the pull ring assembly 1 relative to the insert blade 3, thereby initially performing the anti-rotation locking function and preventing the pull ring assembly 1 from accidentally disengaging from the locked state.

[0056] Meanwhile, the chamfered limiting step 1014 formed in the middle of the pull ring will tightly engage with the plane 3022 at the lower part of the limiting protrusion 302 of the insert blade 3. The close fit between the two further enhances the anti-rotation effect, forming a double anti-rotation guarantee. This double-fit structure can not only effectively limit the rotation of the pull ring assembly 1, but also indirectly limit the rotation of the rotating shaft assembly 2, preventing the locking screw 202 from loosening due to accidental rotation, ensuring the tightness reliability of the puller in the locked state, and providing support for the stable connection between the insert blade 3 and the crossbeam 4.

[0057] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention provides an electronic device for an integrated extraction aid with a quick-locking and locking function, the electronic device comprising: The crossbeam 4 and an integrated pull-out aid with locking and pulling functions that can be quickly tightened are used to perform a first locking operation and a second unlocking operation, wherein the second unlocking operation is the reverse operation of the first locking operation.

[0058] In the first locking operation, the puller is used to securely lock the insert blade 3 to the crossbeam 4, including: Align the rotating shaft assembly 2 with the screw hole of the crossbeam 4, rotate the preset lead to press the insert blade 3 against the crossbeam 4, rotate the horizontal pull ring assembly 1 90° and press it into the position of the limit protrusion 302, and lock the puller in the locked state according to the first locking operation.

[0059] The locking state includes: The plunger pin is elastically engaged with the S-shaped protrusion 3021, and the limiting step 1014 and the plane 3022 are locked together to keep the pull ring assembly 1 in a limited and locked position, and the locking screw 202 cannot rotate.

[0060] Specifically, the crossbeam 4 serves as a mating component of the extraction aid to fasten the insert blade 3. It works in conjunction with the integrated extraction aid to perform a first locking operation (tightening) and a second unlocking operation (loosening). The second unlocking operation is the reverse of the first locking operation. The specific process and locking state of the first locking operation are as follows: In the first locking operation, the extraction aid fastens and locks the insert blade 3 to the crossbeam 4 through multiple steps: First, the rotating shaft assembly 2 of the extraction aid must be aligned with the pre-set screw hole on the crossbeam 4 to ensure the multiple ends of the locking screw 202 are secure. The thread 2021 can precisely align with the threaded hole of the crossbeam 4; then rotate the shaft assembly 2, and using the preset lead of the multi-start thread 2021 of the locking screw 202, rotate no more than two turns, and drive the insert blade 3 to move towards the crossbeam 4 through the thread transmission until the insert blade 3 is tightly pressed against the surface of the crossbeam 4; at this time, the pull ring assembly 1 is in a horizontal state, and it needs to be rotated 90° around the hinge point with the shaft assembly 2, and the pull ring assembly 1 is pressed into the position of the limiting protrusion 302 of the insert blade 3 to complete the first locking operation, so that the puller enters the locked state. The locking state is stably locked through a dual-structure limiting mechanism: on the one hand, the plunger pin on the pull ring assembly 1 slides into and locks itself along the S-shaped protrusion 3021 of the limiting protrusion 302 of the insert blade 3 using its own elasticity, directly restricting the rotation of the pull ring assembly 1; on the other hand, the chamfered limiting step 1014 in the middle of the pull ring is tightly engaged with the plane 3022 at the lower part of the limiting protrusion 302 of the insert blade 3, further assisting in preventing rotation; the dual limiting structure together maintains the limiting and locking state of the pull ring assembly 1, thereby restricting the rotation of the rotating shaft assembly 2, preventing the locking screw 202 from rotating, and ultimately ensuring the stable fastening state of the insert blade 3 on the crossbeam 4, avoiding loosening due to vibration or external force.
