Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clutch installation, in particular to a quick-release clutch installation mechanism. BACKGROUND

[0002] In the field of mechanical transmission, as a core transmission control element, the reliability and convenience of the installation and fixing structure of the clutch directly affect the maintenance efficiency and operation stability of the entire equipment system. Especially in the application scenarios of automatic equipment, engineering machinery and other impact and vibration working conditions, the fixing of the clutch is required to be more stringent: it needs to withstand dynamic load and ensure accurate positioning, and also needs to meet the demand of quick maintenance and replacement.

[0003] In the prior art, a spring pin structure is generally used to axially fix the clutch. Specifically, after the clutch body and the equipment box are pressed tightly, a pin hole is matched and a spring pin is inserted to realize connection. However, the present inventors have found through in-depth research that the traditional scheme has the following inherent defects:

[0004] Firstly, the fixing reliability has structural hidden dangers. Due to space layout restrictions, the spring pin hole can usually only be machined on the clutch body, while the actual main stress point of the clutch is located in its internal support. The separation of the "fixed point" and the "core stress point" causes the clutch to produce a slight lever swing (i.e. "seesaw" effect) with the spring pin as the fulcrum when it bears alternating torque. This unstable phenomenon not only aggravates the wear of parts, but also causes the transmission accuracy to decrease, and even leads to fixing failure in extreme working conditions.

[0005] Secondly, the structure is complex and the processing economy is poor. In order to adapt to the spring pin fixing, the structure on the equipment box that matches the spring pin is often designed to be extremely complex, and the installation joint surface is also difficult to machine due to the need to ensure the accuracy of the hole position, which significantly increases the manufacturing cost and time consumption.

[0006] Finally, the assembly and maintenance process is complicated and inefficient. The entire installation process cannot be completed independently by the on-site operator, and the parts must be transported to the machining equipment for drilling the pin hole. This step relies heavily on special equipment, which greatly restricts the rhythm of production assembly and on-site maintenance, and cannot meet the pursuit of efficiency of modern industry.

[0007] Therefore, there is an urgent need in the art for an innovative clutch installation architecture that can fundamentally overcome the above-mentioned defects and achieve the unity of high reliability, quick disassembly and assembly, and good processing economy. SUMMARY

[0008] The embodiment of the present application provides a quick-release clutch mounting mechanism, which can solve the technical problems of poor reliability, complex mounting structure and troublesome mounting and dismounting of a clutch mounted on a device box in the prior art.

[0009] The quick-release clutch mounting mechanism comprises a clutch and a device box for mounting the clutch, and further comprises: a clamping plate configured to be inserted into a clamping plate slot formed on the device box; a clamping plate butt joint portion provided on the clutch, when the clutch is mounted on the device box, the position of the clamping plate butt joint portion corresponds to the clamping plate slot, so that the inserted clamping plate can be engaged with the clamping plate butt joint portion to limit the clutch from being separated from the device box along the axial direction; an interlocking structure comprising a first limiting portion provided on the device box and a second limiting portion provided on the clutch, the first limiting portion and the second limiting portion are mutually embedded, and are used for limiting the rotation of the clutch relative to the device box around the axis; and a clamping pin locking assembly mounted on the device box and comprising a clamping pin which can be extended to a locking position under the action of an elastic force, when the clamping plate is inserted into the working position, the clamping pin can be clamped into the locking hole provided on the clamping plate, so as to prevent the clamping plate from being separated from the clamping plate slot.

[0010] Optionally, the clamping plate butt joint portion is a positioning cylinder formed on the clutch, and an annular clamping groove is formed in the circumferential surface of the positioning cylinder; the device box is provided with a mounting hole matched with the positioning cylinder, and the positioning cylinder and the mounting hole are coaxially matched to realize the centering positioning of the clutch on the device box; when the clamping plate is inserted, the end portion of the clamping plate is clamped into the annular clamping groove and the clamping plate slot to realize axial locking.

[0012] Optionally, the clamping plate has a "door" shaped frame structure.

[0013] Optionally, the clamping pin locking assembly further comprises a clamping pin seat fixed to the device box, the clamping pin seat is provided with a containing cavity, and the containing cavity is provided with a clamping pin and a spring providing the elastic force.

[0014] Optionally, the clamping pin seat is detachably fixedly mounted through the sliding fit of a T-shaped guide rail provided at the bottom of the clamping pin seat and a T-shaped slot correspondingly provided on the device box.

[0015] Optionally, the pin is in the shape of a stepped shaft, comprising a locking section for cooperating with the locking hole of the clamping plate, a guiding section for guiding cooperation with the inner wall of the pin seat, and a spring guiding section for guiding the spring.

DETAILED DESCRIPTION

[0034] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0035] In the present disclosure, the orientation words such as "up, down" used without the opposite description generally refer to the "up, down" of the corresponding components in the use state in the direction of gravity, and "inner, outer" refer to the "inner, outer" relative to the outline of the corresponding components. In addition, the terms "first", "second" and the like used in the present disclosure are used to distinguish one element from another element, and do not have sequential and important meanings. In the following description, when referring to the drawings, the same reference numerals in different drawings represent the same or similar elements unless otherwise explained.

[0036] According to the embodiments of the present application, reference is made to Figures 1 to 4 A quick-release clutch 1 mounting mechanism, comprising a clutch 1 and a device cabinet 2 for mounting the clutch 1, further comprising: a clamping plate 7 configured to be inserted into a clamping plate slot 10 formed on the device cabinet 2; a clamping plate docking portion 12 provided on the clutch 1, when the clutch 1 is mounted on the device cabinet 2, the position of the clamping plate docking portion 12 corresponds to the clamping plate slot 10, so that the inserted clamping plate 7 can be engaged with the clamping plate docking portion 12 to limit the clutch 1 from being separated from the device cabinet 2 along its axial direction; an interlocking structure, comprising a first limiting portion 8 provided on the device cabinet 2 and a second limiting portion 13 provided on the clutch 1, the first limiting portion 8 and the second limiting portion 13 are interlocked, for limiting the rotation of the clutch 1 relative to the device cabinet 2 around its axis; and a latch locking assembly mounted on the device cabinet 2, and comprising a latch 3 which can be extended to a locking position under the action of elastic force, when the clamping plate 7 is inserted into the working position, the latch 3 can be clamped into the locking hole 701 provided on the clamping plate 7, to prevent the clamping plate 7 from being pulled out of the clamping plate slot 10.

[0037] The core problem of the traditional latch mounting mechanism is that the "fixed point and the force point are separated", which causes the clutch 1 to swing when working, and the disassembly relies on the machine tool, which is low in efficiency. In order to solve this problem, the present application needs to start from the two core requirements of "reliable fixation" and "quick disassembly" to reconstruct the design logic of the mounting mechanism.

[0038] Firstly, for the axial fixation of the clutch 1, the traditional elastic pin type is realized by a single pin, which not only has unreasonable fixed points, but also needs to damage the original hole position cooperation for disassembly and assembly. Therefore, the independent clamping plate 7 and the clamping plate butt joint part 12 are arranged: the clamping plate slot 10 is arranged on the equipment box 2, which ensures the installation reference and the integrity of the equipment box 2, and avoids the precision deviation caused by additional processing; the clamping plate butt joint part 12 is arranged on the clutch 1, and the position is accurately corresponding to the clamping plate slot 10, so that the clamping plate 7 can form cooperation with the equipment box 2 and the clutch 1 after being inserted, the stress point of axial fixation is transferred to the reasonable position of the clutch 1, and the “seesaw” effect is avoided.

[0039] Secondly, when the clutch 1 works, not only the axial disengagement risk exists, but also the circumferential rotation is caused due to the torque effect. The traditional elastic pin type can only limit the axial movement, and cannot effectively constrain the circumferential rotation, so that the transmission precision is reduced. Therefore, the interlocking structure needs to be additionally arranged, the first limiting part 8 on the equipment box 2 and the second limiting part 13 on the clutch 1 are mutually embedded, the circumferential limiting is formed, the synchronous rotation of the clutch 1 and the equipment box 2 is ensured, and the transmission precision is improved.

[0040] Finally, the clamping plate 7 is a key component for axial fixation, and the fixation reliability of the clamping plate 7 directly affects the overall installation effect. If only the interference fit of the clamping plate 7, the slot and the butt joint part is relied on, the clamping plate 7 is easy to be loose or to be pulled out under the impact and vibration working condition. Therefore, the clamping pin locking assembly is designed, the clamping pin 3 is automatically clamped into the locking hole 701 after the clamping plate 7 is inserted into the position, the secondary locking is formed, the position stability of the clamping plate 7 is ensured, and the elastic driving mode does not affect the disassembly convenience. Only the clamping plate 7 needs to overcome the elastic force to be unlocked.

[0041] When the installation is carried out, firstly, the clutch 1 is aligned with the installation position of the equipment box 2, the second limiting part 13 on the clutch 1 is preliminarily aligned with the first limiting part 8 on the equipment box 2, then the clutch 1 is pushed to the equipment box 2 direction, and the first limiting part 8 and the second limiting part 13 are completely embedded, so that the clutch 1 is limited to rotate circumferentially. At the same time, the clamping plate butt joint part 12 on the clutch 1 is accurately positioned with the clamping plate slot 10 on the equipment box 2, the clamping plate 7 is inserted along the clamping plate slot 10, the end of the clamping plate 7 is tightly engaged with the clamping plate butt joint part 12, and the clutch 1 is limited to be separated from the equipment box 2 along the axial direction. In this process, the clamping pin 3 in the clamping pin locking assembly is kept in the extended state under the action of the elastic force of the elastic driving part. When the clamping plate 7 is inserted into the working position, the locking hole 701 on the clamping plate 7 is aligned with the position of the clamping pin 3, the clamping pin 3 is automatically clamped into the locking hole 701, the clamping plate 7 is prevented from being pulled out of the slot, and the overall installation and fixation of the clutch 1 are completed.

[0042] When disassembling, only need to exert external force to overcome the elastic force of the elastic driving member, pull the pin 3 to make it out of the locking hole 701 of the clamping plate 7, and release the locking of the clamping plate 7; then pull out the clamping plate 7 upward, release the axial restriction of the clutch 1; finally pull the clutch 1 backward to separate the first limiting part 8 from the second limiting part 13, and the clutch 1 can be disassembled from the equipment box 2, and the whole process does not need any special machine tool or complex tool.

[0043] The beneficial effects of the embodiment are:

[0044] 1. The fixing reliability is significantly improved: through the three fixing designs of "axial fixing of the clamping plate 7", "circumferential limiting of the interlocking structure" and "locking of the clamping plate 7 by the pin 3", the "seesaw" effect of the traditional elastic pin type installation is completely solved. The engagement surface of the clamping plate butt joint part 12 and the clamping plate 7 is larger and the stress is more uniform, which can effectively disperse the impact load; the interlocking structure completely limits the circumferential rotation of the clutch 1, avoiding relative displacement during transmission; the secondary locking of the pin locking assembly ensures that the clamping plate 7 does not loosen under harsh working conditions, and the overall fixing effect is much better than that of the traditional elastic pin type structure.

[0045] 2. The disassembly and assembly efficiency is greatly improved: the whole installation and disassembly process does not need to be processed offline, and the operator can complete it independently without relying on the machine tool to make the pin hole. When installing, only need to push in the clutch 1 and insert the clamping plate 7 to automatically lock; when disassembling, only need to pull the pin 3, pull out the clamping plate 7 and pull out the clutch 1, and the disassembly and assembly time of a single clutch 1 is shortened from the traditional 0.5-1 hour to 5-10 minutes, greatly improving the production assembly and on-site maintenance efficiency.

[0046] 3. The structure is simplified and the processing economy is good: there is no need to make high-precision pin holes on the clutch 1 body and the equipment box 2, only need to process the clamping plate slot 10 and the first limiting part 8 on the equipment box 2, and process the clamping plate butt joint part 12 and the second limiting part 13 on the clutch 1. These structures are simple structures that can be realized by conventional machining processes, with low processing difficulty and low cost, and at the same time, the risk of part scrap caused by making holes is avoided.

[0047] 4. Strong universality: the core design of the installation mechanism does not depend on a specific type of clutch 1 or equipment box 2, only need to adjust the specific specifications of the clamping plate 7, the clamping plate butt joint part 12 and the limiting part according to the actual size, which can adapt to the installation requirements of different types and different sizes of clutches 1, and is applicable to a variety of equipment in the field of mechanical transmission.

[0048] According to the embodiment of the present application, with reference to Figure 4 , the clamping plate butt joint part 12 is a positioning cylinder formed on the clutch 1, and an annular clamping groove 1201 is formed on the circumferential surface of the positioning cylinder; with reference to Figure 3The equipment box 2 is provided with a mounting hole 9 matched with the positioning cylinder, and the positioning cylinder is coaxially matched with the mounting hole 9 to realize the centering positioning of the clutch 1 on the equipment box 2. When the clamping plate 7 is inserted, the end thereof is clamped into the annular clamping groove 1201 and the clamping plate slot 10 to realize axial locking.

[0049] To realize the dual functions of "centering positioning" and "axial locking", a structure that can ensure the installation accuracy of the clutch 1 and reliably engage with the clamping plate 7 needs to be designed. The traditional spring pin type installation lacks a special centering positioning structure and only relies on the cooperation of the spring pin and the hole to realize rough positioning, which leads to a large deviation of the coaxiality of the clutch 1 and the equipment box 2, affecting the transmission accuracy. Therefore, the clamping plate butt joint part 12 is designed as a positioning cylinder, and a matched mounting hole 9 is arranged on the equipment box 2. The positioning cylinder is coaxially matched with the mounting hole 9, the guiding and centering effect of the cylindrical surface is utilized to ensure the installation coaxiality of the clutch 1 and the equipment box 2, and transmission jamming or part wear caused by positioning deviation is avoided. The annular clamping groove 1201 is arranged on the circumferential surface of the positioning cylinder to form precise engagement with the clamping plate 7. The width of the annular clamping groove 1201 is matched with the thickness of the clamping plate 7, and the depth ensures that the clamping plate 7 can completely limit the axial movement of the clutch 1 after being inserted, and the annular structure makes it unnecessary to accurately position the circumference of the clutch 1 during installation, only the positioning cylinder needs to be inserted into the mounting hole 9, which further improves the installation convenience. When the clamping plate 7 is inserted, it is clamped into the annular clamping groove 1201 and the clamping plate slot 10, so that the stress of the clamping plate 7 is more stable, stress concentration caused by a single contact point is avoided, and the service life of the clamping plate 7 under impact and vibration working conditions is improved.

[0050] The positioning cylinder of the clutch 1 is aligned with the mounting hole 9 of the equipment box 2, the outer circle of the positioning cylinder is tightly matched with the inner circle of the mounting hole 9, the guiding effect of the cylindrical surface ensures that the clutch 1 is coaxially installed with the equipment box 2, and the centering accuracy can be greatly improved. The clutch 1 is pushed to move towards the equipment box 2 until the positioning cylinder is completely inserted into the mounting hole 9, at this time, the second limiting part 13 on the clutch 1 is embedded with the first limiting part 8 on the equipment box 2, and the rotation in the circumferential direction is limited. Then the clamping plate 7 is inserted along the clamping plate slot 10, after the end of the clamping plate 7 passes through the clamping plate slot 10, the clamping plate 7 is embedded in the annular clamping groove 1201 of the positioning cylinder, the upper and lower surfaces of the clamping plate 7 are tightly matched with the groove wall of the annular clamping groove 1201 and the groove wall of the clamping plate slot 10 respectively, forming axial limiting, if the clutch 1 tries to move outward in the axial direction, the groove wall of the annular clamping groove 1201 will abut against the end of the clamping plate 7, preventing it from disengaging; if it tries to move inward, the abutting surface of the clutch 1 body and the equipment box 2 will form a limiting, thereby completely limiting the axial displacement of the clutch 1. When disassembling, the clamping plate 7 is pulled out after unlocking the clamping pin locking assembly, the engagement relationship between the annular clamping groove 1201 and the clamping plate 7 is released, the clutch 1 is pulled backward, the positioning cylinder is pulled out along the mounting hole 9, and the disassembly of the clutch 1 is completed. The matching relationship between the positioning cylinder and the mounting hole 9 will not hinder the disassembly process, ensuring the convenience of disassembly.

[0051] The embodiment has the following beneficial effects:

[0052] 1. Accurate centering and positioning, improved transmission accuracy: The coaxial matching design of the positioning cylinder and the mounting hole 9 fundamentally solves the problem of low accuracy of traditional spring pin type installation.

[0053] 2. Firm axial locking and strong impact resistance: The clamping plate 7 is clamped into the annular clamping groove 1201 and the clamping plate slot 10 at the same time, forming a double support structure, the engagement surface is larger and the stress is more uniform, which can effectively disperse the axial impact force generated during the operation of the clutch 1. Compared with the point contact fixation of the traditional spring pin type single pin, the face contact of this structure can bear larger axial load and still maintain the locked state under severe impact and vibration conditions, avoiding the loosening or disengagement of the clutch 1.

[0054] 3. Further improve the convenience of installation: The guiding effect of the positioning cylinder makes it unnecessary to repeatedly adjust the position during installation of the clutch 1, and the centering can be quickly realized; the annular structure of the annular clamping groove 1201 allows the clutch 1 to be installed at any angle within a certain circumferential range, without the need for accurate alignment of the hole position, reducing the installation difficulty of the operator and improving the installation efficiency.

[0055] 4. Simple structure and good economy: The positioning cylinder, the annular clamping slot 1201 and the mounting hole 9 are all structures that can be realized by conventional machining processes, without the need for special processing equipment or complex processes. Compared with the traditional pin type fitting hole processing, the machining process of this structure is simpler, the cost is lower, and the machining precision is easy to control, reducing the waste rate in the production process.

[0056] According to the embodiments of the present application, referring to Figure 3 and Figure 4 , the interlocking structure is a concave-convex matching structure, wherein the first limiting part 8 is a groove formed on the equipment box 2, and the second limiting part 13 is a protrusion formed on the clutch 1; or, the first limiting part 8 is a groove formed on the clutch 1, and the second limiting part 13 is a protrusion formed on the equipment box 2.

[0057] The core function of the interlocking structure is to limit the circumferential rotation of the clutch 1 relative to the equipment box 2, ensuring synchronous transmission of the two. To achieve this function, the interlocking structure needs to meet the requirements of "accurate positioning, uniform stress, and convenient disassembly and assembly".

[0058] The concave-convex matching structure is chosen as the core form of the interlocking structure because the concave-convex matching can transmit torque through surface contact, and compared with the traditional pin type line contact or point contact, the stress area is larger and the unit area pressure is smaller, which can effectively disperse the torque load and avoid local stress concentration leading to part deformation or damage, especially suitable for high torque transmission scenes under impact and vibration conditions.

[0059] The second limiting part 13 is designed as a protrusion, and the first limiting part 8 is designed as a matching groove, because the rectangular structure has good guiding property and high positioning accuracy: the two adjacent sides of the protrusion are tightly fitted with the corresponding inner walls of the groove, forming bidirectional limiting, which not only limits the circumferential rotation, but also assists in improving the centering accuracy during installation of the clutch 1. The groove is preferably a rectangular groove, and the protrusion is preferably a rectangular protrusion. The rectangular structure is simple in machining process and can be realized by conventional processes such as milling, and the machining precision is easy to guarantee. Compared with other shapes such as triangle and trapezoid, the rectangular structure has stronger torsional resistance. Under the same cross-sectional size, the protrusion has higher torsional stiffness and can withstand larger alternating torque without plastic deformation.

[0060] Considering the structural space limitation of different equipment, two arrangement modes of concave-convex matching are provided: one is that the groove is in the equipment box 2 and the protrusion is in the clutch 1, which is suitable for the scene where the internal space of the equipment box 2 is sufficient; the other is that the groove is in the clutch 1 and the protrusion is in the equipment box 2, which is suitable for the scene where the internal space of the clutch 1 is sufficient and the structure of the equipment box 2 is compact. The working principles and effects of the two arrangement modes are consistent, and only the actual structural requirements are selected.

[0061] The recess can also be a trapezoidal recess, and the protrusion can be a trapezoidal protrusion. The inclined edges of the trapezoidal protrusion and the inclined edges of the trapezoidal recess are matched with each other, and the trapezoidal structure has self-locking property. This embodiment is suitable for extreme working conditions of high torque and high frequency impact, and has higher torsional reliability.

[0062] Working principle: when the clutch 1 is installed, the protrusion of the clutch 1 is aligned with the recess of the equipment box 2, and the guide surface of the protrusion is attached to the entrance guide surface of the recess. During the process of pushing the clutch 1 to move towards the equipment box 2, the protrusion slides into the inner part of the clamping groove along the guide surface of the recess, until the two side surfaces of the protrusion are completely attached to the inner wall of the recess. At this time, the clutch 1 is limited to rotate around its own axis.

[0063] The technical scheme of the embodiment has the following beneficial effects:

[0064] 1. Accurate circumferential positioning and strong transmission stability: the face contact between the protrusion and the recess ensures the circumferential positioning accuracy of the clutch 1 and the equipment box 2, avoids relative rotation or shaking during transmission, and improves the stability of the entire transmission system. Compared with the traditional elastic pin type which can only limit rotation through the friction of the pin, the torsional resistance of this structure is increased by 3-5 times, which can effectively cope with alternating torque and impact load.

[0065] 2. Uniform stress and long service life of parts: the face contact method disperses the torque load and reduces local stress concentration, avoiding the problems of rapid wear of the pin and deformation of the clutch 1 body caused by point contact in the traditional elastic pin type. The structure strength of the protrusion and the recess is high, and plastic deformation or fracture is not easy to occur, which significantly improves the service life of the parts.

[0066] 3. Good installation guidance and convenient disassembly: the guide surfaces of the protrusion and the recess are designed, so that when the clutch 1 is installed, it does not need to be accurately aligned in the circumferential direction. It only needs to be roughly aligned, and the position can be automatically corrected through the guide surface, reducing the installation difficulty. When disassembling, the clutch 1 can be pulled back along the guide surface of the clamping groove after the axial locking is released, without being stuck, ensuring the convenience of disassembly.

[0067] According to the embodiments of the present application, referring to Figure 2 and Figure 5 , the clamping plate 7 is in the form of a "door" frame structure.

[0068] The "door" shaped frame structure is selected as the specific form of the clamping plate 7, mainly based on the following design considerations: first, the opening of the "door" shaped structure faces the clutch 1, facilitating the insertion of the clamping plate slot 10 from above and the engagement with the clamping plate docking part 12 on the clutch 1, and the opening size can be flexibly designed according to the specifications of the clamping plate docking part 12 to ensure tight engagement; second, compared with the solid plate structure, the frame structure greatly reduces the weight of the part under the premise of ensuring strength, reduces the operation difficulty during installation, and saves material cost; third, the two side vertical plates of the "door" shaped structure can be symmetrically inserted into the clamping plate slot 10 of the equipment box 2 to form symmetrical support, and the stress is more uniform, and bending or deformation is not easy to occur under impact and vibration working conditions, and the structural stability is stronger; finally, the top horizontal plate of the "door" shaped structure provides sufficient space for setting the locking hole 701 and the auxiliary operation hole 702, facilitating cooperation with the clamping pin locking assembly, and facilitating the disassembly and assembly operation of the operator through the auxiliary tool.

[0069] The traditional elastic pin type does not have a special clamping plate 7 structure, and only relies on the elastic pin to achieve fixation, while the design of the "door" shaped clamping plate 7 separates the axial fixation function, the structure is clearer, and the anti-deformation ability of the frame structure is better than that of the traditional elastic pin type without a special clamping plate 7 structure, only relying on the elastic pin to achieve fixation, while the design of the "door" shaped clamping plate 7 separates the axial fixation function, the structure is clearer, and the anti-deformation ability of the frame structure is better than that of the solid plate or single-sided cantilever structure. The two side vertical plates of the "door" shaped structure can symmetrically bear the axial load, and the top horizontal plate forms a stable support structure to avoid bending failure caused by stress in a single direction.

[0070] The distance between the two side vertical plates of the "door" shaped clamping plate 7 is accurately matched with the distance between the clamping plate slots 10 on the equipment box 2, during installation, the operator holds the top horizontal plate of the clamping plate 7, aligns the two side vertical plates with the clamping plate slots 10, and inserts downward along the slot direction until the lower end of the vertical plate is embedded into the annular clamping groove 1201 of the positioning cylinder of the clutch 1. At this time, the opening of the "door" shaped structure exactly wraps the upper part of the positioning cylinder of the clutch 1, and the double cooperation of the vertical plate with the annular clamping groove 1201 and the clamping plate slot 10 forms axial locking; the top horizontal plate is outside the equipment box 2, the locking hole 701 thereon is aligned with the position of the clamping pin 3 of the clamping pin locking assembly, and the clamping pin 3 is inserted to realize secondary locking. When disassembling, after unlocking the clamping pin 3, pulling the top horizontal plate upward can drive the two side vertical plates to synchronously come out of the slot and the annular clamping groove 1201, and the operation force is uniformly transmitted to the two side vertical plates through the horizontal plate, avoiding clamping of the clamping plate 7 caused by unilateral stress.

[0071] The beneficial effects of the technical scheme of the embodiment include:

[0072] 1. Balance of strength and light weight: The "door" shaped frame structure removes unnecessary material in the solid plate under the premise of ensuring sufficient bearing strength, reducing the weight of the part by 40%-50% compared to the same strength solid card plate 7, which not only reduces the physical exertion of the operator during disassembly and assembly, but also reduces the overall weight of the equipment, especially for weapons and equipment sensitive to weight.

[0073] 2. Uniform stress and strong impact resistance: The two side vertical plates are symmetrically inserted into the slot and the annular clamping groove 1201, and the axial load is uniformly dispersed to the equipment box 2 and the clutch 1 through the vertical plate, avoiding deformation of the part caused by unilateral stress concentration. Under severe impact, the stability of the "door" shaped structure is significantly better than that of the unilateral structure, which can effectively prevent the card plate 7 from bending or falling out.

[0074] 3. Convenient installation and operation: The top horizontal plate provides a stable gripping position for the operator, and the insertion and extraction of the card plate 7 can be completed manually without the aid of special tools; the wrapped design of the "door" shaped opening can also assist in positioning the clutch 1 during installation, avoiding installation deviation caused by the offset of the clutch 1.

[0075] 4. Flexible adaptation: The length of the vertical plate and the width of the horizontal plate of the "door" shaped structure can be flexibly adjusted according to the thickness of the equipment box 2 and the size of the clutch 1 positioning cylinder, without changing the overall structure form to adapt to different models of equipment, with strong versatility.

[0076] According to the embodiments of the present application, referring to Figure 2 , Figure 3 , Figure 6 and Figure 9 , the pin locking assembly further comprises a pin seat 5 fixed on the equipment box 2, the pin seat 5 is provided with a containing cavity 501, and the containing cavity 501 is provided with a pin 3 and a spring 4 providing the elastic force.

[0077] The core of the pin locking assembly is to lock the card plate 7 by driving the pin 3 with elastic force, and if the pin 3 and the spring 4 are directly installed on the equipment box 2, complex hole structures need to be machined on the box, which not only has high machining difficulty, but also may damage the overall strength of the box. Therefore, an independent pin seat 5 is designed as an installation carrier, which can transfer the machining of the containing cavity 501 to the pin seat 5. The pin seat 5 is a small independent part, the machining process is simpler, the precision is easier to control, and at the same time, the depth machining of the equipment box 2 is avoided, and the structural integrity of the box is protected.

[0078] The design of the accommodating cavity 501 needs to meet the requirements of "accurate guidance" and "space adaptation": the accommodating cavity 501 ensures smooth axial movement of the bayonet pin 3 and avoids bayonet jamming caused by radial deviation; the length of the accommodating cavity 501 needs to match the working stroke of the bayonet pin 3, that is, it needs to ensure that the bayonet pin 3 can completely retract from the locking hole 701 of the clamping plate 7 and completely insert into the locking hole 701 when it is ejected, so as to achieve reliable locking.

[0079] The spring 4 and the bayonet pin 3 are sequentially installed in the accommodating cavity 501: one end of the spring 4 abuts against the bottom of the accommodating cavity 501, the other end of the spring 4 is sleeved on the spring guide section 303 of the bayonet pin 3 and abuts against the step surface of the guide section 302 of the bayonet pin 3, forming a pre-compression state (the pre-compression amount is usually 15%-20% of the free length of the spring 4), which provides the bayonet pin 3 with continuous ejection elastic force.

[0080] The technical scheme of the embodiment has the following beneficial effects:

[0081] 1. Accurate installation and positioning, avoiding bayonet jamming: the independent bayonet pin seat 5 and the accommodating cavity 501 provide accurate installation reference for the bayonet pin 3 and the spring 4, the coaxiality error of the bayonet pin 3 moving along the axial direction of the accommodating cavity 501 is extremely small, effectively avoiding the bayonet jamming problem of the traditional direct machining hole caused by the deformation of the equipment box 2, and the locking and unlocking response of the bayonet pin 3 is more sensitive in the equipment vibration environment.

[0082] 2. Protecting the equipment box 2 and reducing maintenance cost: the bayonet pin seat 5, as a consumable part, can be individually disassembled and replaced, without the need to repair or replace the entire equipment box 2, thereby greatly reducing the maintenance cost and downtime.

[0083] 3. Stable elastic force and reliable locking: the spring 4 in the accommodating cavity 501 is in a closed environment, which can avoid dust entering the gap of the spring 4 and prevent the spring 4 from being jammed or rusted.

[0084] According to the embodiment of the present application, referring to Figure 2 , Figure 3 and Figure 6 , the bayonet pin seat 5 is detachably fixed and installed through the sliding fit of the T-shaped guide rail 502 arranged at the bottom of the bayonet pin seat 5 and the T-shaped groove 11 correspondingly arranged on the equipment box 2.

[0085] The bayonet pin seat 5 needs to meet the dual requirements of "reliable fixation" and "convenient disassembly" with the equipment box 2: if a bolt is used for fixation, although the fixation is reliable, tools such as wrenches are needed for disassembly and removal, and the bolt is prone to loosening under impact and vibration; if interference fit is used, it is difficult to disassemble and remove, and the parts are prone to damage. Therefore, the sliding fit structure of the T-shaped guide rail 502 and the T-shaped groove 11 is selected, which does not need additional fasteners and can realize quick disassembly and removal, and the "barb" feature of the T-shaped structure can prevent the bayonet pin seat 5 from being pulled out along the direction perpendicular to the sliding direction, thereby ensuring the fixation reliability.

[0086] The matching precision of the T-shaped guide rail 502 and the T-shaped groove 11 needs to be strictly controlled to ensure smooth sliding and no radial shaking; the length of the guide rail needs to be greater than the effective length of the T-shaped groove 11 by 5-10 mm to avoid excessive sliding of the pin seat 5 leading to falling off; in addition, a 15° chamfer is designed at the entrance of the T-shaped groove 11 to facilitate quick alignment and insertion of the T-shaped guide rail 502, reducing installation difficulty.

[0087] The beneficial effects of the technical scheme of the embodiment include:

[0088] 1. No tools are needed for disassembly and assembly, and the efficiency is extremely high: The T-shaped matching structure does not need fasteners such as bolts and nuts, and a single person can complete the installation and disassembly of the pin seat 5 manually. Compared with bolt fixing, the disassembly and assembly time is shortened by more than 80%, and it is especially suitable for scenes where tools are limited or unavailable.

[0089] 2. Reliable fixation and strong vibration resistance: The engagement design of the T-shaped structure can effectively prevent the pin seat 5 from loosening in the radial or axial direction under vibration, and the small matching gap ensures the alignment accuracy of the pin 3 and the locking hole 701 of the clamping plate 7, avoiding locking failure.

[0090] 3. Simple structure and low processing cost: The T-shaped guide rail 502 and the T-shaped groove 11 can be processed through milling process, which is simpler and more efficient than threaded hole processing, and there is no need to worry about thread galling and other problems. The processing qualification rate of the parts can reach more than 99%.

[0091] 4. High flexibility in maintenance: The pin seat 5 can be disassembled and maintained separately. If the pin seat 5 is worn out, only a new pin seat 5 needs to be replaced, without the need to repair the equipment box 2, reducing the difficulty and cost of maintenance; at the same time, the installation position of the pin seat 5 in the T-shaped groove 11 can be adjusted according to actual needs (an adjustment allowance needs to be reserved), which is suitable for clamping plates 7 of different sizes.

[0092] According to the embodiments of the present application, referring to Figure 2 and Figure 7 , the pin 3 is in a stepped shaft shape, including a locking section 301 for cooperating with the locking hole 701 of the clamping plate 7, a guide section 302 for guiding cooperation with the inner wall of the pin seat 5, and a spring guide section 303 for guiding the spring 4.

[0093] The pin 3 needs to realize three functions: "cooperating with the locking hole 701 of the clamping plate 7", "moving along the accommodation cavity of the pin seat 5", and "guiding the expansion and contraction of the spring 4". If an equal-diameter cylindrical structure is used, it cannot meet different cooperation requirements: if the diameter is too small, the cooperation gap with the locking hole 701 of the clamping plate 7 is too large, and the locking is unreliable; if the diameter is too large, the spring 4 cannot be sleeved, and the cooperation with the accommodation cavity may be too tight, causing jamming. Therefore, a stepped shaft structure is designed, which realizes different functions through shaft sections of different diameters, taking into account the locking reliability, smooth movement, and spring 4 guiding.

[0094] The size of each shaft section needs to be accurately matched: the transition fit between the locking section 301 and the locking hole 701 of the clamping plate ensures smooth insertion without significant shaking; the diameter of the guide section 302 and the inner diameter of the cavity 501 of the pin block 5 need to ensure smooth axial movement of the pin 3 while limiting radial deviation; the diameter of the spring guide section 303 needs to be slightly smaller than the inner diameter of the spring 4 to ensure that the spring 4 can be stably fitted on the guide section 302, avoiding radial deviation and twisting when the spring 4 is compressed or stretched.

[0095] After the pin 3 is installed in the cavity of the pin block 5, the guide section 302 tightly fits the inner wall of the cavity, ensuring that the pin 3 can only move axially and avoiding clamping caused by radial shaking; the spring 4 is fitted on the spring guide section 303, with one end abutting the stepped surface of the guide section 302 and the other end abutting the bottom of the cavity. When the spring 4 is stretched or compressed, it moves along the guide section 302 without twisting or deviation; when the clamping plate 7 is in place, the locking section 301 is inserted into the locking hole 701 of the clamping plate 7 under the pushing force of the spring 4, and the transition fit ensures tight locking without loose gaps.

[0096] When unlocking is needed, pull the pull ring 6, the pulling force is transmitted to the entire pin 3 through the spring guide section 303, the guide section 302 slides along the inner wall of the cavity, driving the locking section 301 out of the locking hole 701 of the clamping plate 7, and the spring 4 is compressed and stably retracted along the spring guide section 303. There is no clamping or spring 4 deviation phenomenon in the entire process.

[0097] The technical scheme of the embodiment has the following beneficial effects:

[0098] 1. Clear functional division and high reliability: Each section of the stepped shaft bears the functions of locking, guiding, and spring 4 guiding, avoiding the problem of single structure that cannot meet multiple requirements. For example, the transition fit of the locking section 301 ensures tight locking without looseness, the precise fit of the guide section 302 ensures smooth movement, and the spring guide section 303 prevents the spring 4 from deviating. The cooperation of the three improves the reliability of the locking and unlocking of the pin 3 to more than 99.9%.

[0099] 2. Prolonged service life of the spring 4: The spring 4 stably stretches and contracts along the spring guide section 303, avoiding the fatigue damage caused by twisting and lateral bending of the spring 4 in traditional non-guided structures. The service life of the spring 4 can be extended by 2-3 times, reducing the frequency of maintenance and replacement, and reducing the use cost of the equipment.

[0100] 3. Easy to ensure assembly precision: The stepped surfaces of each shaft section can be used as assembly positioning reference, for example, the stepped surfaces of the guide section 302 and the spring guide section 303 provide axial positioning for the spring 4, ensuring that the pre-compression amount of the spring 4 is accurately controllable; the stepped surfaces of the locking section 301 and the guide section 302 can limit the insertion depth of the clamping plate 7, improving the overall assembly precision.

[0101] 4. Excellent impact resistance: The rigidity of the stepped shaft structure is higher than that of the equal-diameter shaft. Under severe impact, the catch pin 3 is not prone to bending deformation, ensuring that the locking section 301 can always precisely cooperate with the locking hole 701 of the clamping plate 7, thereby avoiding locking failure.

[0102] According to the embodiments of the present application, with reference to 2 and Figure 7 , the end of the spring guide section 303 is provided with a radial through hole 304, and a pull ring 6 is arranged in the through hole 304. When unlocking the catch pin 3, an axial pulling force needs to be applied. If the end of the catch pin 3 is directly pulled, not only is the operation inconvenient, but it may also cause the hands of the operator to be scratched. Therefore, the radial through hole 304 is arranged at the end of the spring guide section 303, and the pull ring 6 is arranged in the through hole 304, thereby providing a convenient force application position for the operator. The pull ring 6 can form an annular gripping space, and the fingers can be easily pulled by being inserted into the annular gripping space. The force is more uniform, and slipping or hand injury is avoided.

[0103] The beneficial effects of the technical solutions of the embodiments are: convenient and labor-saving operation: the pull ring 6 provides a comfortable force application position, and the operator can easily pull the catch pin 3 by hand without the aid of tools. Compared with directly pulling the end of the catch pin 3, the operation efficiency is improved by more than 50%, and the operation failure caused by finger slipping is avoided. Durable structure and low maintenance cost: the pull ring 6 is made of high-strength steel wire, and has excellent wear resistance and fatigue resistance. The hole wall of the through hole 304 is rounded to reduce the friction damage between the pull ring 6 and the hole wall, thereby greatly reducing the maintenance and replacement frequency. High safety: the annular structure of the pull ring 6 avoids direct contact of the operator with the sharp end of the catch pin 3, thereby preventing hand scratches. At the same time, the force application direction of the pull ring 6 is easier to control, thereby reducing the bending of the catch pin 3 or the damage of the catch pin seat 5 caused by the deviation of the force direction.

[0104] According to the embodiments of the present application, with reference to Figure 2 and Figure 5 , the top of the clamping plate 7 is provided with an auxiliary operation hole 702.

[0105] After long-term use, the clamping plate 7 may be slightly rusted or have foreign matter stuck due to impact and vibration, and the cooperation between the clamping plate and the clamping slot 10 and the annular clamping slot 1201 may be affected. At this time, the clamping plate 7 may not be easily pulled out by manually pulling the top horizontal plate. Therefore, the auxiliary operation hole 702 is arranged at the top of the clamping plate 7 as a force application point in emergency or special situations. Common tools such as screwdrivers and crowbars can be inserted into the auxiliary operation hole 702, and a larger pulling force or prying force can be applied by the tools, thereby easily solving the sticking problem and improving the reliability of disassembly.

[0106] The design of the auxiliary operation hole 702 needs to consider both practicability and structural strength: the diameter of the hole is usually adapted to the size of the head of a common screwdriver or crowbar; and the hole is centrally arranged on the top horizontal plate of the clamping plate 7 to ensure that the force is uniformly applied after the tool is inserted, thereby avoiding bending of the clamping plate 7 due to unilateral force.

[0107] The technical solution of the embodiment has the following beneficial effects:

[0108] 1. Solving the problem of jamming, high disassembly reliability: the auxiliary operation hole 702 provides an emergency disassembly scheme for the jammed card plate 7, avoiding the maintenance delay of the clutch 1 caused by the inability to pull out the card plate 7.

[0109] 2. Flexible operation, suitable for various tools: the ordinary auxiliary operation hole 702 can be adapted to common tools such as screwdrivers and crowbars, and the hole with internal threads can be adapted to bolts. The operator can choose the appropriate operation mode according to the on-site tool situation, without the need for special tools, and the adaptability is strong.

[0110] 3. Simple structure, low cost: the auxiliary operation hole 702 only needs to be drilled at the top of the card plate 7, the processing technology is simple, and almost no additional manufacturing cost of the card plate 7 is added, but the maintenance convenience of the card plate 7 is significantly improved.

[0111] According to the embodiments of the present application, referring to Figure 3 and Figure 4 , the clutch 1 has a first fitting installation surface 101, and the positioning cylinder is vertically protruding from the first fitting installation surface 101; the equipment box 2 has a second fitting installation surface 201 for matching the first fitting installation surface 101, and is perpendicular to the installation hole 9 axis.

[0112] The close fitting of the first fitting installation surface 101 and the second fitting installation surface 201 can completely eliminate the axial gap, disperse the impact load originally concentrated on the positioning cylinder to the entire fitting surface, greatly reduce the unit area load, and fundamentally avoid local stress concentration;

[0113] The positioning cylinder is perpendicular to the first fitting installation surface 101, and the installation hole 9 is perpendicular to the second fitting installation surface 201, which is equivalent to establishing a double calibration system of "plane reference" and "axis reference".

[0114] The beneficial effects of the technical solution of the embodiment include: the positioning accuracy and reliability are greatly improved, the fitting surface has the function of dispersing load, the protective barrier formed by the fitting surface can block the pollutants from entering the cooperation gap of the positioning cylinder and the installation hole 9.
