[0066] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description is not meant to limit the application to all of the embodiments described herein. Rather, the following description is meant to provide examples of methods and apparatuses consistent with the application as detailed in the appended claims.

[0067] The terms "first", "second", "third", "fourth" and the like in the description and in the claims, if any, of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of these terms herein is to be construed to cover a general order and / or structure unless there is a context indicating in any other manner. Furthermore, the use of the terms first, second, third, fourth, etc. herein to describe a process, method, action, operation, step, etc. is only to identify such processes, methods, actions, operations, steps, etc. as being distinct from other processes, methods, actions, operations, steps, etc. that have been previously described or will be described below. However, these terms are not necessarily used herein to identify or describe any specific sequential order or chronology of events, steps, or functions.

[0068] In the related art, some covers and boxes are provided with a support rod. After the cover is opened, the support rod is inserted into the support position on the cover or the box to keep the cover open. When closing the cover, one hand needs to hold the cover and the other hand needs to take out the support rod to close the cover. Some covers and boxes are provided with a support rod and a slide rail at the same time. The upper end of the support rod is rotationally connected with the cover, the lower end of the support rod is slidingly connected with the slide rail, and the slide rail is connected with the box. When the cover is opened, the lower end of the support rod is driven to slide along the slide rail to the limit position to keep the cover open. When closing the cover, one hand needs to hold the cover and the other hand needs to return to slide the support rod to close the cover. Both of them are not convenient for single-handed closing operation, which affects the use experience.

[0069] To solve the above problems in the prior art, the application provides a guide rail mechanism, a tool box and engineering machinery. The guide rail mechanism provided by the application comprises a support, a sliding piece and a connecting piece. The support is connected to a covered piece, and at least one first limiting groove is arranged on the support. The sliding piece is slidingly arranged on the support. The connecting piece is rotatably connected to the covered piece and slidingly connected to the support. When the covered piece covering the covered piece is opened, the connecting piece slides relative to the support under the driving of the covered piece. Part of the connecting piece slides into the first limiting groove, so that the covered piece is kept at a preset opening degree relative to the covered piece. The single-handed cover opening operation is realized. When the covered piece is continuously turned over, the connecting piece is separated from the first limiting groove under the driving of the covered piece. After the connecting piece is separated from the first limiting groove, the sliding piece can slide relative to the support and close the first limiting groove. The connecting piece can slide reversely relative to the support, and the covered piece is arranged on the covered piece to complete the cover closing. When the covered piece is arranged on the covered piece, the sliding piece opens the first limiting groove, and the single-handed cover closing operation is realized. Therefore, the single-handed opening and closing operation is facilitated, and the use experience is improved.

[0070] The technical solutions of the application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described in detail in some examples.

[0071] In the first aspect, referring to Figures 1-14 The guide rail mechanism provided by the embodiments of the application comprises a support 100, a sliding piece 200 and a connecting piece 300.

[0072] The support 100 is connected to the covered piece 10. The support 100 is provided with at least one first limiting groove 101.

[0073] The sliding piece 200 is slidingly arranged on the support 100.

[0074] The connecting piece 300 is rotatably connected to the covered piece 20, and the connecting piece 300 is slidingly connected to the support 100.

[0075] The connecting piece 300 is configured to slide relative to the support 100 under the driving of the covered piece 20 when the covered piece 20 covering the covered piece 10 is opened. Part of the connecting piece 300 slides into the first limiting groove 101, so that the covered piece 20 is kept at a preset opening degree relative to the covered piece 10.

[0076] The connecting piece 300 is configured to be separated from the first limiting groove 101 under the driving of the covered piece 20 when the covered piece 20 is continuously turned over.

[0077] The sliding piece 200 is configured to slide relative to the support piece 100 and close the first limiting slot 101 after the connecting piece 300 is disengaged from the first limiting slot 101, so that the connecting piece 300 can slide reversely relative to the support piece 100, and the cover piece 20 can be covered on the covered piece 10. Alternatively, the first limiting slot 101 is opened when the cover piece 20 is covered on the covered piece 10.

[0078] The covered piece 10 in the embodiment can be a box, a container or the like, and the cover piece 20 can be a cover body, a cover plate or the like. One side of the cover piece 20 can be rotatably connected to the covered piece 10, and the cover piece 20 can be flipped along a horizontal axis to open or close the covered piece 10.

[0079] The guide rail mechanism in the embodiment is used for the rotation opening and closing between the cover piece 20 and the covered piece 10. As shown in Figure 1 、 Figure 9 The covered piece 10 can have a substantially rectangular cavity structure, and has an accommodation cavity inside to store tools, components or the like. The covered piece 10 has an opening at the top. The cover piece 20 has a substantially plate structure, and is covered on the opening. One side of the cover piece 20 can be rotatably connected to the covered piece 10 through a rotating shaft, a hinge or the like. In addition, the side of the cover piece 20 away from the rotating connection can be provided with a locking device for locking with the covered piece 10.

[0080] The support piece 100 in the embodiment can have a plate shape, a strip shape or the like, and can be fixedly connected to the covered piece 10 through screwing, clamping, bonding or the like, such as the inner side wall of the covered piece 10. The extension direction of the support piece 100 is substantially consistent with the horizontal direction and perpendicular to the rotating axis of the cover piece 20. The support piece 100 is provided with one or more first limiting slots 101. The first limiting slot 101 is an open slot with an upward or upwardly inclined opening. When there are multiple first limiting slots 101, they are arranged at intervals along the extension direction of the support piece 100.

[0081] The sliding piece 200 in the embodiment can also have a plate shape, a strip shape or the like, and can be arranged on the support piece 100 through a sliding assembly or a sliding structure. The sliding piece 200 substantially slides along the horizontal direction and towards or away from the rotating axis of the cover piece 20.

[0082] The connecting piece 300 in the embodiment can have a rod shape, a plate shape, a strip shape or the like. The upper end of the connecting piece 300 can be rotatably connected to the cover piece 20 through a rotating shaft or a rotating structure. The lower end of the connecting piece 300 can be connected to the support piece 100 through a sliding part or a sliding structure, and can slide relative to the support piece 100 along the horizontal direction and towards or away from the rotating axis of the cover piece 20.

[0083] Specifically, when the cover 20 is flipped open, the cover 20 causes the connecting member 300 to slide relative to the support member 100 in a direction closer to the rotation axis of the cover 20, such as... Figure 6 As shown in the X-axis direction, when the cover 20 is slid to the first limiting groove 101, it is released, and part of the connecting piece 300 falls into the first limiting groove 101 to support the cover 20 and keep it at a preset opening degree, thus realizing one-handed opening operation. The preset opening degree can be set according to actual needs, and is not specifically limited in this embodiment.

[0084] When the cover 20 is flipped open, the connecting member 300 disengages from the first limiting groove 101 under the action of the cover 20. At this time, the sliding member 200 can slide relative to the support member 100 and close the first limiting groove 101 under the action of the connecting member 300 or the action of the driving component (i.e., the component that can drive the sliding member 200 to slide relative to the support member 100 and close the first limiting groove 101, such as a cylinder, hydraulic cylinder, electric push rod, etc.), so that the opening of the first limiting groove 101 remains flat, so that the connecting member 300 can slide in the opposite direction relative to the support member 100. After the connecting member 300 slides smoothly through the first limiting groove 101, the cover 20 covers the cover 10, realizing the one-handed closing operation.

[0085] When the cover 20 is placed on the cover 10, the slider 200 is reset, which opens the first limiting groove 101 so that the cover 20 falls into the first limiting groove 101 when it is opened again.

[0086] It is understandable that, compared to the operation of closing the cover in the prior art that requires both hands, the application of the guide rail mechanism provided in this application embodiment can facilitate the opening and closing of the cover 20 on the cover 10 with one hand, thus improving the user experience.

[0087] Thus, the guide rail mechanism provided in the embodiments of the present application comprises a support 100, a sliding member 200 and a connecting member 300. The support 100 is connected to the covered member 10, and at least one first limiting groove 101 is arranged on the support 100. The sliding member 200 is arranged on the support 100 in a sliding manner. The connecting member 300 is rotatably connected to the covering member 20, and is slidably connected to the support 100. When the covering member 20 covering the covered member 10 is opened, the connecting member 300 is driven by the covering member 20 to slide relative to the support 100, and part of the connecting member 300 slides into the first limiting groove 101, so that the covering member 20 is kept at a preset opening degree relative to the covered member 10, and the single-hand opening operation is realized. When the covering member 20 is continuously flipped, the connecting member 300 is driven by the covering member 20 to disengage from the first limiting groove 101. After the connecting member 300 disengages from the first limiting groove 101, the sliding member 200 can slide relative to the support 100 to close the first limiting groove 101, so that the connecting member 300 can slide reversely relative to the support 100, and the covering member 20 is arranged on the covered member 10 to complete the closing. In addition, when the covering member 20 is arranged on the covered member 10, the first limiting groove 101 is opened, and the single-hand closing operation is realized, so that the single-hand opening and closing operation is facilitated, and the use experience is improved.

[0088] In a possible design, the guide rail mechanism further comprises a linkage assembly 400 arranged on the support 100 and located at the first limiting groove 101.

[0089] The linkage assembly 400 is configured to limit the connecting member 300 when the covering member 20 covering the covered member 10 is opened, and part of the connecting member 300 is driven by the covering member 20 to slide relative to the support 100 to the opening position of the first limiting groove 101, so that part of the connecting member 300 slides into the first limiting groove 101.

[0090] The linkage assembly 400 is further configured to release the limitation on the connecting member 300 when the covering member 20 is continuously flipped, the connecting member 300 is driven by the covering member 20 to disengage from the first limiting groove 101, and the connecting member 300 slides reversely relative to the support 100.

[0091] In this way, when the covering member 20 is flipped and opened, the linkage assembly 400 can limit the connecting member 300, so that the connecting member 300 cannot slide into the first limiting groove 101 accurately. When the connecting member 300 disengages from the first limiting groove 101, and the connecting member 300 slides reversely relative to the support 100, the linkage assembly 400 no longer limits the connecting member 300.

[0092] Further, in the embodiment, the linkage assembly 400 comprises a limiting piece 410, which is rotationally arranged on the support piece 100, and is located above the first limiting groove 101.

[0093] The limiting piece 410 is configured to abut against one side of the connecting piece 300 when the covering piece 20 is opened and the connecting piece 300 is slid to the opening position of the first limiting groove 101 under the driving of the covering piece 20, and stop after being deflected to the limit position under the driving of the connecting piece 300, so as to limit the opening of the covering piece 20; and when part of the connecting piece 300 is slid into the first limiting groove 101, the limiting piece 410 is reversely deflected to reset, so as to release the limitation.

[0094] The limiting piece 410 is further configured to abut against the other side of the connecting piece 300 when the covering piece 20 is continuously flipped and the connecting piece 300 is disengaged from the first limiting groove 101 under the driving of the covering piece 20, and reversely deflect under the driving of the connecting piece 300 when the connecting piece 300 is reversely slid relative to the support piece 100, so as to release the limitation; and when the connecting piece 300 is disengaged from the limiting piece 410, the limiting piece 410 is deflected to reset.

[0095] Specifically, as shown in Figure 4 , Figure 5 The linkage assembly 400 in the embodiment at least comprises a limiting piece 410 for preventing the opening of the covering piece 20 from being too large to make the sliding part 310 slide through the first limiting groove 101, and the limiting piece 410 can be a limiting plate, a limiting sheet, a limiting bracket, etc. The limiting piece 410 can be rotationally connected to the support piece 100 through a rotating shaft or a rotating structure, and the rotating axis thereof is parallel to the rotating axis of the covering piece 20.

[0096] The limiting piece 410 has a limiting part 411 thereon for stopping or releasing the stopping of the sliding end of the connecting piece 300, and the limiting part 411 can be a first limiting protrusion or a first limiting tooth. The limiting piece 410 is located above the first limiting groove 101, and the limiting part 411 can be directed downward to the first limiting groove 101 by a resetting component or gravity.

[0097] When the covering piece 20 is opened and the connecting piece 300 is slid to the opening position of the first limiting groove 101 under the driving of the covering piece 20, part of the connecting piece 300 abuts against one side of the limiting part 411, as shown in Figure 6 The connecting piece 300 drives the limiting piece 410 to deflect to the limit position, i.e. the limiting part 411 is deflected towards the rotating axis of the covering piece 20, and the deflection direction is as shown in Figure 8As shown in the Y-axis direction, the limiting member 410 stops deflecting and restricts the lateral sliding of the connecting member 300, releasing the cover 20 so that the connecting member 300 falls into the first limiting groove 101, part of the connecting member 300 disengages from the limiting part 411, and the limiting member 410 deflects back to its original position in the opposite direction, thereby preventing the opening of the cover 20 from being too large and causing the connecting member 300 to slide past the first limiting groove 101.

[0098] As the cover 20 continues to flip, driven by the cover 20, the connector 300 disengages from the first limiting groove 101, and as the connector 300 slides in the opposite direction relative to the support 100, a portion of the connector 300 abuts against the other side of the limiting part 411, such as... Figure 10 , Figure 11 As shown, part of the connector 300 causes the limiting member 410 to deflect in the opposite direction, the connector 300 disengages from the limiting part 411 and continues to slide in the opposite direction, the limiting member 410 deflects back to its original position, that is, the limiting part 411 does not restrict the reverse sliding of the connector 300.

[0099] The specific shape and structure of the limiting member 410 can be determined according to actual needs, and no excessive restrictions are imposed in this embodiment.

[0100] Furthermore, in this embodiment, the linkage component 400 also includes an elastic reset member 420, which is connected to the limiting member 410 and is used to deflect the limiting member 410 back to its original position.

[0101] Specifically, such as Figure 4 As shown, the elastic reset member 420 can be a spring, elastic strip, etc., which is connected to the limiting member 410 and the support member 100 respectively, and is used to keep the limiting member 410 in its original position, prevent it from deflecting freely with vibration, and ensure stability.

[0102] The elastic force of the elastic reset member 420 should not be too large to avoid excessive deflection resistance of the limiting member 410. The elastic force, specific specifications, and connection structure between the elastic reset member 420 and the limiting member 410 can be determined according to actual needs, and no specific limitation is made in this embodiment.

[0103] Alternatively, a stop structure can be provided between the limiting member 410 and the support member 100 to limit the deflection range of the limiting member 410.

[0104] For example, such as Figure 8 , Figure 14 As shown, the limiting member 410 has a notch on the side opposite to the limiting part 411, and the two sides of the notch have a first stop part and a second stop part, such as a stop surface or a stop wall. Correspondingly, the support member 100 is provided with a third stop part, such as a stop post or a stop pin. The third stop part is located between the first stop part and the second stop part.

[0105] When the limiting member 410 is deflected to the limit position, as shown in Figure 8 , the third stop portion abuts against the first stop portion to limit the limiting member 410 from continuing to deflect. When the limiting member 410 is reversely deflected to the second position, as shown in Figure 14 , the third stop portion abuts against the second stop portion to limit the limiting member 410 from continuing to deflect.

[0106] In this way, it can be further ensured that the opening of the covering member 20 is not too large to cause the connecting member 300 to slide through the first limiting slot 101. Of course, the limiting member 410 and the support member 100 can also be replaced by other types of limiting structures, and any structure capable of limiting the deflection range of the limiting member 410 can be used, and the present embodiment is not limited in this regard.

[0107] In some embodiments, the connecting member 300 is further configured to, when the covering member 20 is continuously flipped over and the connecting member 300 is disengaged from the first limiting slot 101 and continues to slide relative to the support member 100 under the driving of the covering member 20, drive the sliding member 200 to slide relative to the support member 100 and close the first limiting slot 101.

[0108] The connecting member 300 is further configured to, when the connecting member 300 reversely slides relative to the support member 100 and the covering member 20 is placed on the to-be-covered member 10, drive the sliding member 200 to reversely slide relative to the support member 100 and open the first limiting slot 101.

[0109] In this way, the sliding member 200 can be driven to slide by the connecting member 300 to close or open the first limiting slot 101, thereby achieving a linkage effect and making the structure more compact and the operation more convenient.

[0110] Further, in the present embodiment, the support member 100 is provided with a first sliding groove 102, and the first limiting slot 101 is located on the bottom surface of the first sliding groove 102.

[0111] The sliding member 200 is provided with a second sliding groove 201, and the second sliding groove 201 is parallel to the first sliding groove 102. The second sliding member 200 is further provided with a second limiting slot 202 on the bottom surface of the second sliding groove 201, and the second limiting slot 202 corresponds to the first limiting slot 101.

[0112] The connecting member 300 is provided with a sliding portion 310, and the sliding portion 310 is in sliding connection with the first sliding groove 102 and the second sliding groove 203.

[0113] The sliding portion 310 is configured to, when the covering member 20 placed on the to-be-covered member 10 is opened and the connecting member 300 slides relative to the support member 100 under the driving of the covering member 20, slide along the first sliding groove 102 and the second sliding groove 203 and slide into the first limiting slot 101 and the second limiting slot 202.

[0114] Specifically, as shown in Figure 4 , the first sliding groove 102 and the second sliding groove 201 can both be long grooves, and the long grooves extend along the horizontal direction and close to or away from the rotation axis direction of the cover 20. At least one of the first sliding groove 102 and the second sliding groove 201 is a closed groove, that is, the upper end of the sliding groove is not opened, so as to ensure that the sliding part 310 can stably slide in the first direction or the reverse direction. The first limiting groove 101 is located on the bottom surface of the first sliding groove 102.

[0115] The bottom surface of the second sliding groove 201 is provided with one or more second limiting grooves 202. The second limiting groove 202 is an open groove, and the opening is upward or obliquely upward. When there are multiple second limiting grooves 202, they are arranged at intervals along the extension direction of the sliding part 200. The shape, size and position of the second limiting groove 202 correspond to the first limiting groove 101 one by one. In the initial state, the second limiting groove 202 is aligned with the first limiting groove 101.

[0116] The lower end of the connecting piece 300 has a sliding part 310, such as a sliding rod, a sliding column, a sliding block, etc. The sliding part 310 matches the first sliding groove 102 and the second sliding groove 201, and the sliding part 310 can slide in the first sliding groove 102 and the second sliding groove 201 along the horizontal direction close to or away from the rotation axis of the cover 20.

[0117] The length of the first limiting groove 101 is greater than the length of the first sliding groove 102, so that when the sliding part 310 is in the two limit positions in the first sliding groove 102, the sliding part 310 can drive the sliding part 200 to slide. For example, as shown in Figure 6 , when the cover 20 is not opened, the left ends of the first sliding groove 102 and the second sliding groove 201 are aligned, and the right ends are not aligned. When the cover 20 is continuously turned over, under the driving of the cover 20, when the sliding part 310 is disengaged from the first limiting groove 101, the sliding part 310 abuts against the right end of the second sliding groove 201 and drives the sliding part 200 to slide in the first direction, until the right ends of the first sliding groove 102 and the second sliding groove 201 are aligned, the first limiting groove 101 and the second limiting groove 202 are misaligned to be filled, so that the sliding part 310 can smoothly slide in the reverse direction through the first limiting groove 101 and the second limiting groove 202.

[0118] For another example, Figure 12As shown, after the cover 20 is fully opened, the right ends of the first sliding groove 102 and the second sliding groove 201 are aligned, and the left ends are not aligned. When the cover 20 is flipped in the reverse direction, the sliding part 310 is reversely slid relative to the support 100 under the driving of the cover 20, the sliding part 310 abuts against the left end of the second sliding groove 201, and drives the sliding part 200 to slide in the reverse direction of the first direction, until the left ends of the first sliding groove 102 and the second sliding groove 201 are aligned, and the first limiting groove 101 and the second limiting groove 202 are re-aligned, so that the sliding part 310 can be slid into the first limiting groove 101 and the second limiting groove 202 again when the cover 20 is opened next time. The specific length of the first sliding groove 102 and the second sliding groove 201 can be determined according to actual needs, and is not limited in the embodiment.

[0119] Further, in the embodiment, the first limiting groove 101 is inclined towards the sliding direction of the connecting part 300, and forms an included angle θ with the extension direction of the first sliding groove 102, the included angle θ is an acute angle, and the first limiting groove 101 and the second limiting groove 202 are in the same direction.

[0120] Alternatively, a plurality of first limiting grooves 101 are arranged along the extension direction of the first sliding groove 102, and a plurality of second limiting grooves 202 are arranged along the extension direction of the second sliding groove 201, and the first limiting grooves 101 and the second limiting grooves 202 correspond one by one.

[0121] Specifically, as shown, Figure 10 the openings of the first limiting groove 101 and the second limiting groove 202 are upward and inclined towards the side deviating from the rotation axis of the cover 20, so that the included angle θ formed by the first limiting groove 101 and the extension direction of the first sliding groove 102 is an acute angle.

[0122] In this way, on the one hand, when the cover 20 is continuously opened, the sliding part 310 can easily escape from the first limiting groove 101 and the second limiting groove 202. On the other hand, when the cover 20 is subjected to violent vibration in the external environment, the sliding part 310 is prevented from easily escaping from the first limiting groove 101 and the second limiting groove 202.

[0123] The specific size of the included angle θ can be determined according to actual design needs, and is not limited in the embodiment.

[0124] Further, a plurality of first limiting grooves 101 and a plurality of second limiting grooves 202 are arranged along the first direction, that is, two or more first limiting grooves 101 and two or more second limiting grooves 202 are arranged along the horizontal direction and towards or away from the rotation axis of the cover 20, and the first limiting grooves 101 and the second limiting grooves 202 correspond one by one.

[0125] In this way, the cover 20 can be maintained at different opening degrees. Specifically, the opening degree of the cover 20 is greater when the sliding part 310 falls into the first limiting groove 101 and the second limiting groove 202 which are closer to the rotation axis of the cover 20.

[0126] It should be noted that the linkage component 400 needs to be set at the first limiting groove 101 closest to the rotation axis of the cover 20. The specific number and spacing of the first limiting groove 101 and the second limiting groove 202 can be determined according to actual needs, and no restrictions are imposed in this embodiment.

[0127] In some embodiments, one of the support member 100 and the slider 200 is provided with a sliding protrusion 103, and the other is provided with a sliding groove 203 that matches the sliding protrusion 103, and the sliding groove 203 is slidably connected to the sliding protrusion 103.

[0128] In one example, such as Figure 4 , Figure 5 As shown, the sliding protrusion 103 can be connected to the support member 100 by means of plugging, welding, snap-fitting, etc. The sliding groove 203 matches the sliding protrusion 103, and the sliding protrusion 103 and the sliding groove 203 are slidably connected to ensure that the slider 200 slides stably on the support member 100 and to limit the sliding distance of the slider 200.

[0129] In another example, not shown in the figure, the sliding protrusion 103 can also be provided on the slider 200, and the sliding groove 203 matches the sliding protrusion 103. The sliding groove 203 is provided on the support 100, and the sliding protrusion 103 and the sliding groove 203 are slidably connected, which can also ensure that the slider 200 slides stably on the support 100 and limit the sliding distance of the slider 200.

[0130] Of course, the support member 100 and the sliding member 200 can also be replaced by other types of sliding structures, depending on the actual needs. This embodiment does not impose too many restrictions.

[0131] In addition, such as Figure 4 , Figure 5 As shown, a mounting component 110 can also be provided on the support component 100. This component can be a mounting plate, mounting block, mounting bracket, etc., and can be connected to the side wall of the support component 100 by means of screwing, snap-fitting, welding, etc. A mounting cavity matching a portion of the sliding component 200 is left between the mounting component 110 and the support component 100, so that a portion of the sliding component 200 is inserted into the mounting cavity and slides relative to the support component 100, thereby preventing the sliding component 200 from falling off the support component 100 and ensuring the stability of the sliding.

[0132] Of course, the mounting structure between the sliding member 200 and the support member 100 can also be replaced by other types of mounting structures, and any structure that can ensure the stable sliding of the sliding member 200 in the first direction or the reverse direction can be used, and the present embodiment is not limited in this regard.

[0135] Specifically, the box body has a receiving cavity therein, and the upper end of the box body has an opening. The support member 100 can be fixedly connected to the box body by screwing, clamping, bonding or the like, for example, on the inner side wall of the box body near the opening. The connecting member 300 can be connected to the cover body by a rotating shaft or a hinge on the side of the cover body that faces the box body. The side of the connecting member 300 that is away from the cover body can slide in the horizontal direction towards or away from the rotation axis of the box body, and the sliding member 200 can also slide in the horizontal direction towards or away from the rotation axis of the box body.
