Description

Technical Field

[0001] This invention relates to the field of product handling technology, and more particularly to handling accessories. Background Technology

[0002] The existing transfer process for LED (Light-Emitting Diode) displays often involves two methods: manually moving the LED cabinet or using U-shaped hooks.

[0003] Handling LED cabinets by hand is unsafe and prone to damage to the LED chips due to human error. While using U-shaped hooks provides a convenient lifting position for the movers, the LED cabinets still pose a risk of falling off during transport, resulting in poor safety. Summary of the Invention

[0004] The purpose of this invention is to provide a handling accessory for transporting boxes, preventing the boxes from falling off and improving safety.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Transporting attachments, including:

[0007] handle;

[0008] A snap-fit ​​assembly, two of which are spaced apart and connected to both ends of the handle respectively; each snap-fit ​​assembly includes a housing and a slider telescopically disposed in the housing, the slider being used to snap-fit ​​with the housing;

[0009] A limiting assembly, the limiting assembly including a limiting member that passes through the slider and slides on the housing, the limiting member having a first state that locks the slider inside the housing, and a second state that releases the slider from the housing.

[0010] As an optional handling accessory, the housing includes a base and a cover plate covering the base. The slider includes a main body and a first sliding part and a second sliding part respectively connected to both ends of the main body. The base is provided with a first sliding groove, a second sliding groove and a third sliding groove. The main body slides in the third sliding groove, the first sliding part slides in the first sliding groove, and the second sliding part slides in the second sliding groove. The limiting member passes through the second sliding part, and the first sliding part is used to extend from the base and engage with the housing.

[0011] As an optional solution for handling accessories, the limiting component includes a limiting block, and the base is also provided with a mounting groove. The limiting member passes through the limiting block and is slidably connected to the limiting block. One end of the limiting member can extend out of the housing, and the other end of the limiting member can pass through the second sliding part. The sliding direction of the limiting member intersects with the sliding direction of the second sliding part. When the limiting member is in the first state, the other end of the limiting member is placed in the second sliding part to prevent the first sliding part from sliding out of the housing. When one end of the limiting member is pressed into the limiting block, the other end of the limiting member can extend out from the second sliding part to release the slider from locking in the housing.

[0012] As an optional solution for handling accessories, a limiting sliding hole is provided on the second sliding part, the limiting sliding hole extends along the sliding direction of the second sliding part, and a first stop is provided at the other end of the limiting member, and a first positioning groove is provided on the second sliding part. When the limiting member is in the first state, the first stop is embedded in the first positioning groove; when one end of the limiting member is pressed into the limiting block, the first stop can disengage from the first positioning groove.

[0013] As an alternative to handling accessories, the inner wall of the second slide is recessed into a relief groove, and when the limiting member is in the second state, the first stop is placed in the relief groove.

[0014] As an optional solution for handling accessories, the limiting component further includes a first elastic element, which is disposed within the limiting block and sleeved on the limiting member. The first elastic element is used to allow one end of the limiting member to extend out of the outer shell.

[0015] As an alternative to the handling attachment, the snap-fit ​​assembly further includes a second elastic element, one end of which abuts against the main body and the other end of which abuts against the side wall of the third slide groove. The second elastic element is used to push the main body to slide along the third slide groove.

[0016] As an optional handling accessory, the handling accessory further includes a reset assembly, which includes a reset rod that passes through the main body. The base is also provided with a guide hole that extends along the sliding direction of the main body, and one end of the reset rod is slidably connected to the guide hole.

[0017] As an optional solution for handling accessories, one end of the reset rod is provided with a second stop and the base has a second positioning groove. When the slider is engaged with the housing, the second stop is embedded in the second positioning groove.

[0018] As an optional solution for handling accessories, a third elastic element is sleeved on the reset rod. One end of the third elastic element abuts against the inner wall of the base, and the other end abuts against the second positioning boss arranged circumferentially on the reset rod. The third elastic element enables the reset rod to move away from the base and causes the second stop to be embedded in the second positioning groove.

[0019] Beneficial effects:

[0020] In this invention, the slider of the snap-fit ​​assembly snaps into the housing, facilitating user operation. The limiting component ensures that the slider is stably locked inside the housing or released from the housing, allowing assemblers to easily switch the connection state with the housing during use. Simultaneously, the limiting component prevents the slider from loosening, improving the reliability and stability of the connection. This effectively prevents the accessory from separating from the housing during transport, thus avoiding the housing from falling off and significantly enhancing safety. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0050] Please see the appendix Figure 1-4This embodiment relates to a handling accessory (hereinafter referred to as the "accessory"). The accessory includes a handle 1, a snap-fit ​​assembly 2, and a limiting assembly 3. Two snap-fit ​​assemblies 2 are spaced apart and connected to both ends of the handle 1 respectively. The snap-fit ​​assembly 2 includes a housing and a slider 21 telescopically disposed within the housing, the slider 21 being used to snap into the housing 100. The limiting assembly 3 includes a limiting member 31, which passes through the slider 21 and slides within the housing. The limiting member 31 has a first state that locks the slider 21 within the housing, and a second state that releases the slider 21 from the housing.

[0051] In this embodiment, the handle 1 is a rod-shaped component that is convenient for the handler to grip. The handle 1 can be made of a non-metallic material with a certain rigidity and hardness, or it can be made of a metallic material to improve wear resistance. Of course, the shape of the handle 1 can be processed into a concave shape that is convenient for the fingers to grip, so as to improve the handling experience. The interior of the handle 1 can be hollow to reduce the weight of this accessory.

[0052] In fact, to facilitate the cooperation between the housing 100 and this accessory and to aid in the operation of handling personnel, mounting holes are provided on the side wall of the housing 100. The slider 21 of the snap-fit ​​assembly 2 engages with the mounting holes, achieving a reliable connection between the accessory and the housing 100. Specifically, the same accessory has two sets of snap-fit ​​assemblies 2, with two sets of sliders 21 extending in opposite directions and engaging with the housing 100. Furthermore, the limiting member 31 can stably lock the slider 21 within the housing, or release it from the housing, ensuring that assembly personnel can easily switch the connection state with the housing 100 during use. Simultaneously, the limiting member 31 releases the slider 21 from the housing, preventing it from loosening, thus improving the reliability and stability of the connection and effectively preventing the accessory from separating from the housing 100 during handling, thereby enhancing safety.

[0053] Please continue to refer to the appendix. Figure 5 Optionally, the outer casing includes a base 22 and a cover plate 23 covering the base 22. The slider 21 includes a main body 211 and a first sliding part 212 and a second sliding part 213 respectively connected to both ends of the main body 211. The base 22 is provided with a first sliding groove 221, a second sliding groove 222 and a third sliding groove 223. The main body 211 slides in the third sliding groove 223, the first sliding part 212 slides in the first sliding groove 221, and the second sliding part 213 slides in the second sliding groove 222. The limiting member 31 passes through the second sliding part 213, and one end of the first sliding part 212 is used to extend from the base 22 and engage with the housing 100.

[0054] In this embodiment, the outer shell consists of two parts, specifically a base 22 and a cover plate 23. The base 22 is connected to the end of the handle 1 by threaded fasteners. After the two outer shells are connected to the handle 1, they form a U-shaped structure. The cover plate 23 covers the base 22, and the connection between the base 22 and the cover plate 23 can be achieved by multiple threaded fasteners to fix the internal structure of the outer shell. The entire outer shell is an inverted L-shape. The base 22 has a first sliding groove 221, a second sliding groove 222, and a third sliding groove 223 inside. The first sliding groove 221 and the second sliding groove 222 are connected to the third sliding groove 223. The first sliding groove 221, the second sliding groove 222, and the third sliding groove 223 are used to accommodate the first sliding part 212, the second sliding part 213, and the main body 211 of the slider 21, respectively. The first sliding part 212 and the second sliding part 213 are connected to both ends of the main body 211, making the slider 21 U-shaped. The slider 21 can be a one-piece structure or a separate connection structure of the first sliding part 212, the second sliding part 213, and the main body 211. The slider 21 can move along the first direction X, which is the engagement direction of the slider 21 and the housing 100. Furthermore, one end of the first sliding part 212 can extend out of the base 22 during the sliding process and abut against the inner wall of the mounting hole of the housing 100, thereby achieving engagement between the two. The limiting member 31 is a rod-shaped member arranged along the second direction Y, wherein the second direction Y is perpendicular to the first direction X. The limiting member 31 passes through the second sliding part 213. The slider 21 can be locked by the compression cooperation between the circumferential outer wall of the limiting member 31 and the second sliding part 213.

[0055] Furthermore, the limiting component 3 includes a limiting block 32, and the base 22 is also provided with a mounting groove 224. The limiting member 31 passes through the limiting block 32 and is slidably connected to the limiting block 32. One end of the limiting member 31 can extend out of the outer shell, and the other end of the limiting member 31 can pass through the second sliding part 213. The sliding direction of the limiting member 31 intersects with the sliding direction of the second sliding part 213. When the limiting member 31 is in the first state, the other end of the limiting member 31 is placed in the second sliding part 213 to prevent the first sliding part 212 from sliding out of the outer shell. When one end of the limiting member 31 is pressed into the limiting block 32, the other end of the limiting member 31 can extend out from the second sliding part 213 to release the slider 21 from being locked in the outer shell.

[0056] In this embodiment, the base 22 is provided with a mounting groove 224 extending along the second direction Y, wherein the limiting block 32 is fixed in the mounting groove 224. The limiting block 32 can be fixedly connected to the base 22 by a threaded fastener. The limiting member 31 passes through the limiting block 32 along the second direction Y, one end of which can extend out of the outer shell, and the other end passes through the second sliding part 213. Before the accessory is snapped into the housing 100, one end of the limiting member 31 extends out of the base 22 and the limiting block 32, and the other end of the limiting member 31 is placed in the second sliding part 213. The first sliding part 212 is located inside the outer shell. When it is necessary to snap the accessory into the housing 100, by squeezing one end of the limiting member 31, the other end of the limiting member 31 is disengaged from the second sliding part 213, so that the slider 21 is released from the housing, and the second sliding part 213 can extend out of the housing and snap into the housing 100.

[0057] Specifically, there are two ways to press one end of the limiting member 31. First, after the outer shell portion is inserted into the housing 100, the operator holds the handle 1 and presses along the second direction Y, causing one end of the limiting member 31 to retract inwards and separating the other end of the limiting member 31 from the second sliding part 213, thus releasing the slider 21 from the outer shell. Second, after the outer shell portion is inserted into the housing 100, the operator manually presses the limiting member 31, causing one end to retract inwards and separating the other end of the limiting member 31 from the second sliding part 213, thus releasing the slider 21 from the outer shell. These two methods are applicable to situations where the depth of engagement between the housing 100 and this accessory is different. Those skilled in the art can flexibly choose the appropriate method based on the actual operating conditions.

[0058] Please see the appendix Figure 1 Appendix Figure 6 and attached Figure 7 Optionally, a limiting sliding hole 2131 is provided on the second sliding part 213, the limiting sliding hole 2131 extends along the sliding direction of the second sliding part 213, the other end of the limiting member 31 is provided with a first stop 33, and the second sliding part 213 is provided with a first positioning groove 2132. When the limiting member 31 is in the first state, the first stop 33 is embedded in the first positioning groove 2132; when one end of the limiting member 31 is pressed into the limiting block 32, the first stop 33 can disengage from the first positioning groove 2132.

[0059] In this embodiment, the second sliding part 213 is a straight rod slidably disposed within the second sliding groove 222. The second sliding part 213 has a limiting sliding hole 2131 extending along the first direction X. The limiting sliding hole 2131 serves as a guide during the sliding engagement between the limiting member 31 and the second sliding part 213. The limiting sliding hole 2131 is an oblong hole. Further, a first positioning groove 2132 is formed by recessing the second sliding part 213 at the end away from the limiting block 32. The first positioning groove 2132 is used to accommodate and limit the first stop block 33 at the other end of the limiting member 31. In this embodiment, the first stop block 33 is a circular piece, fixed to the other end of the limiting member 31 by screws. The cross-sectional shape of the first positioning groove 2132 is also circular to accommodate the first stop block 33. The diameter of the first stop block 33 is larger than the diameter of the limiting member 31, that is, the diameter of the first positioning groove 2132 is larger than the width of the limiting sliding hole 2131.

[0060] Before this accessory is engaged with the housing 100, one end of the limiting member 31 extends out of the base 22 and the limiting block 32, the first stop block 33 is placed in the first positioning groove 2132, and the first sliding part 212 is located inside the housing. When it is necessary to engage this accessory with the housing 100, by squeezing one end of the limiting member 31, the first stop block 33 at the other end of the limiting member 31 is disengaged from the first positioning groove 2132 along the second direction Y. The second sliding part 213 can slide relative to the limiting member 31. At this time, the limiting member 31 releases the lock on the slider 21, the slider 21 can slide along the first direction X, and one end of the first sliding part 212 slides out from the base 22.

[0061] Please continue to refer to the appendix. Figure 5 Optionally, the inner wall of the second slide groove 222 is recessed inward with a relief groove 2221. When the limiting member 31 is in the second state, the first stop block 33 is placed in the relief groove 2221.

[0062] In this embodiment, the first stop 33, along with the limiting member 31, disengages from the first positioning groove 2132 along the first direction X and can be directly inserted into the clearance groove 2221. The clearance groove 2221 is set directly opposite the first stop 33. The setting of the clearance groove 2221 avoids the minimum width limitation of the second sliding groove 222, which can conveniently reduce the gap between the second sliding part 213 and the second sliding groove 222, and ensure the stability of the sliding limit.

[0063] Please see the appendix Figure 2 Furthermore, the limiting component 3 also includes a first elastic element 34, which is disposed inside the limiting block 32 and sleeved on the limiting component 31. The first elastic element 34 is used to make one end of the limiting component 31 extend out of the outer shell.

[0064] In this embodiment, the first elastic member 34 is a standard spring, the outer periphery of the limiting member 31 is provided with a first positioning boss 311, the first elastic member 34 is sleeved on the limiting member 31 and is placed inside the limiting block 32, one end of the first elastic member 34 abuts against the end face of the first positioning boss 311, and the other end abuts against the second sliding part 213.

[0065] Before this accessory is engaged with the housing 100, one end of the limiting member 31 extends out of the base 22 and the limiting block 32, the first stop block 33 is placed in the first positioning groove 2132, and the first sliding part 212 is located inside the housing. At this time, the first elastic member 34 can be unaffected or subjected to a small compressive force. When this accessory needs to be snapped into the housing 100, by squeezing one end of the limiting member 31, the first stop 33 at the other end of the limiting member 31 is disengaged from the first positioning groove 2132 along the second direction Y. At this time, the first elastic member 34 is compressed, the second sliding part 213 slides relative to the limiting member 31, and the first stop 33 is misaligned with the first positioning groove 2132. Under the rebound action of the first elastic member 34, the first stop 33 presses against the wall surface of the second sliding part 213. At this time, the first elastic member 34 is always under pressure. When the first sliding part 212 is retracted into the base 22 under the action of external force, the second sliding part 213 is reset, the first stop 33 is opposite to the first positioning groove 2132, and under the elastic recovery action of the first elastic member 34, the first stop 33 is repositioned into the first positioning groove 2132, so that the slider 21 is locked in the housing.

[0066] Please continue to refer to the appendix. Figure 2 Furthermore, the snap-fit ​​assembly 2 also includes a second elastic member 24, one end of which abuts against the main body 211 and the other end of which abuts against the side wall of the third slide groove 223. The second elastic member 24 is used to push the main body 211 to slide along the third slide groove 223.

[0067] In this embodiment, two second elastic members 24 are provided, respectively located on the side of the main body 211 near the first sliding part 212 and the side near the second sliding part 213. The second elastic member 24 can also be a standard spring. A limiting groove for limiting the second elastic member 24 is provided on the main body 211. The size of the limiting groove matches the diameter of the second elastic member 24. At the same time, one end of the second elastic member 24 is placed in the limiting groove and abuts against the bottom wall of the limiting groove, while the other end abuts against the inner wall of the base 22, specifically the side wall of the third sliding groove 223.

[0068] By setting the second elastic element 24, when the limiting member 31 is in the first state of locking the slider 21 in the housing, the second elastic element 24 is compressed and deformed by the pressure of the main body 211 and stores energy. When the limiting member 31 is in the second state of releasing the slider 21 from the housing, the elasticity of the second elastic element 24 is restored, which will push the slider 21 to slide so that the first sliding part 212 extends out from the base 22 and automatically completes the engagement with the housing 100.

[0069] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 Optionally, the transport accessory also includes a reset assembly 4, which includes a reset rod 41 that passes through the main body 211. The base 22 is also provided with a guide hole 225 that extends along the sliding direction of the main body 211. One end of the reset rod 41 is slidably connected to the guide hole 225.

[0070] In this embodiment, the reset rod 41 passes through the main body 211 along the third direction Z. The third direction Z is perpendicular to the plane formed by the first direction X and the second direction Y. A guide hole 225 is provided in the base 22. The guide hole 225 extends along the first direction X. The guide hole 225 can be elongated or waist-shaped. The reset rod 41 passes through the guide hole 225 and can slide inside the guide hole 225.

[0071] Furthermore, please refer to the attached document. Figure 8 A movable hole 231 is provided on the cover plate 23 corresponding to the guide hole 225. After the reset rod 41 passes through the guide hole 225, it passes through the movable hole 231. The other end of the reset rod 41 extends out of the cover plate 23 through the movable hole 231. The movable hole 231 is used to avoid the reset rod 41. A button cap 44 is also provided on the side of the reset rod 41 that extends out of the cover plate 23. Since the reset rod 41 needs to be subjected to force frequently during the use of the accessory, in this embodiment, a limiting platform is also provided on the main body 211 along the extension direction of the reset rod 41. The reset rod 41 passes through the limiting platform, and the limiting platform and the reset rod 41 pass through the movable hole 231 at the same time. The limiting platform can be used to help strengthen the deformation resistance of the reset rod 41 when subjected to force.

[0072] The mover can manually push the button cap 44 in the opposite direction of the first sliding part 212 extending out of the outer shell to retract the first sliding part 212 into the outer shell, thereby releasing the snap-fit ​​relationship between the housing 100 and this accessory.

[0073] Please see the appendix Figure 8 - Appendix Figure 12 Optionally, a second stop 42 is provided at one end of the reset rod 41, and a second positioning groove 226 is provided on the base 22. When the slider 21 is engaged with the housing 100, the second stop 42 is embedded in the second positioning groove 226.

[0074] In this embodiment, the second positioning groove 226 is provided on the outer wall of the base 22, and the second stop 42 is also a circular part. The second stop 42 is fixed to one end of the reset rod 41 by screws. When the second elastic member 24 squeezes the slider 21 to make the first sliding part 212 extend from the base 22 and engage with the housing 100, the second stop 42 is embedded in the second positioning groove 226 to make the slider 21 self-lock in its sliding direction. Through the limiting effect of the second positioning groove 226 on the second stop 42, it is ensured that other factors (such as vibration factors) can be avoided during the engagement of this accessory and the housing 100 to prevent the slider 21 from disengaging in the opposite direction, thereby improving the reliability and stability of the engagement.

[0075] Please see the appendix Figure 13 Appendix Figure 14 Appendix Figure 16 and appendix Figure 17 Optionally, a third elastic element 43 is sleeved on the reset rod 41. One end of the third elastic element 43 abuts against the inner wall of the base 22, and the other end abuts against the second positioning boss 411 arranged circumferentially on the reset rod 41. The third elastic element 43 can make the reset rod 41 move away from the base 22 and make the second stop 42 embedded in the second positioning groove 226.

[0076] In this embodiment, the third elastic element 43 is a common standard spring. The third elastic element 43 is sleeved on the reset rod 41 and the second positioning boss 411 is arranged circumferentially. The reset rod 41 passes through the main body 211. The third elastic element 43 is disposed inside the main body 211. One end of the third elastic element 43 abuts against the inner wall of the base 22, and the other end abuts against the end face of the second positioning boss 411.

[0077] Before this accessory is engaged with the housing 100, the slider 21 is entirely located inside the housing, the third elastic element 43 is deformed by compression, and the second stop 42 is misaligned with the second positioning groove 226. When this accessory is engaged with the housing 100, the slider 21, under the action of the second elastic element 24, causes the first sliding part 212 to extend from the base 22 and automatically engage with the housing 100. At this time, the third elastic element 43 returns to its original shape, placing the second stop 42 in the second positioning groove 226.

[0078] The following describes the assembly process of this attachment.

[0079] Please see the appendix Figure 1 - Appendix Figure 2 Appendix Figure 5 With attachment Figure 13 - Appendix Figure 18During installation, firstly, the first elastic element 34 is fitted onto the limiting element 31, with one end abutting against the first positioning boss 311. Then, the limiting element 31 and the first elastic element 34 are inserted into the limiting block 32. Further, the other end of the limiting element 31 is passed through the second sliding part 213 of the slider 21, specifically through the limiting sliding hole 2131, and the first stop block 33 is screwed onto the limiting element 31.

[0080] Next, place the second elastic element 24 between the slider 21 and the base 22, and then place the assembled limiting component 3 and the slider 21 into the base 22 respectively. Specifically, place the first sliding part 212 into the first sliding groove 221, the second sliding part 213 into the second sliding groove 222, the main body 211 into the third sliding groove 223, and the limiting block 32 into the mounting groove 224.

[0081] Then, fix the button cap 44 to one end of the reset rod 41, and fit the third elastic member 43 on the other end, so that one end of the third elastic member 43 abuts against the second positioning boss 411, and the other end of the reset rod 41 passes through the main body 211 and through the guide hole 225, so that the second stop 42 is screwed to the other end of the reset rod 41.

[0082] Finally, the cover plate 23 is fastened to the base 22, and the cover plate 23 is connected to the base 22 by multiple screws.

[0083] The following details the operation process and the working principle of the internal structure of this appendix.

[0084] Please see the appendix Figure 1 - Appendix Figure 2 Appendix Figure 5 - Appendix Figure 12Before use, one end of the limiting member 31 extends out of the outer shell. The first stop 33 is fitted into the first positioning groove 2132 under the elastic force of the first elastic member 34. The first sliding part 212 is located inside the outer shell. At this time, under the action of the limiting member 31, the main body 211 is located on the far left, and the second elastic member 24 is pressed. The reset rod 41 is in the pressed state, and the second stop 42 is misaligned with the second positioning groove 226. When the accessory is engaged with the housing 100, the operator holds the handle 1 and inserts part of the engaging component 2 into the interior of the housing 100. Simultaneously, the first stop 33 is lifted up and disengaged from the first positioning groove 2132 by the wall of the housing 100 pressing the limiting member 31. As the limiting effect of the limiting member 31 is released, the slider 21 slides under the action of the second elastic member 24, causing the first sliding part 212 to extend out of the housing and complete the snap-fit. At the same time, the second stop 42 at the other end of the reset rod 41 moves to be opposite to the second positioning groove 226. Under the elastic recovery action of the third elastic member 43, the second stop 42 is embedded in the second positioning groove 226, ensuring that the slider 21 will not loosen after snap-fit. After the housing 100 is moved to the designated location, this accessory needs to be removed from the housing 100. Specifically, the operator can manually press the button cap 44 to push the second stop 42 out of the second positioning groove 226 and continue to push the button cap 44 in the opposite direction of the first sliding part 212 to reset the slider 21 in the reverse direction. At this time, the second elastic element 24 is compressed. After it is fully reset, the first stop 33 is opposite to the first positioning groove 2132. Under the elastic recovery of the first elastic element 34, one end of the limiting member 31 extends out of the outer shell, and the first stop 33 is embedded in the first positioning groove 2132. The locking state is released, and the operator can easily remove this accessory from the housing 100.
