Description

Technical Field

[0001] This utility model relates to the technical field of components for operating machinery, and in particular to a fixing device for an engine hood support rod and operating machinery including the fixing device. Background Technology

[0002] The engine hood of the work machinery can be opened for maintenance and is supported by a strut. One end of the strut (the movable end) is fixed to the engine hood, while the other end is hinged to a location in the engine compartment. When the engine hood is closed, the movable end of the strut can be stored inside the work machinery, such as on a side panel of the engine compartment. A "clip" or "slot" structure is provided at this location to secure the movable end of the strut.

[0003] Existing clips for securing struts may include a snap-fit ​​portion for securing the strut and a clip mounting portion for mounting to an engine compartment. The clip is mounted to a wall panel, for example, within the engine compartment, by passing a fastener through a screw hole in the clip mounting portion. Such a structure is prone to damage when the strut is pulled out or placed with excessive force, and the need for fasteners (e.g., bolts, nuts) increases the installation process and the number of parts required. Furthermore, it requires a larger installation space, which is detrimental to cost reduction and improved installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the above-mentioned problems and / or other problems existing in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a fixing device is provided for fixing an engine hood support rod. The fixing device includes a first bracket and a fixing buckle connected to the first bracket. The first bracket is provided with a mounting hole. The fixing buckle includes a mounting structure and a support rod fixing structure. The mounting structure includes two opposing first plate portions. The support rod fixing structure includes two opposing second plate portions. The two second plate portions are respectively connected to the two first plate portions to form two opposing plate-like members. The two plate-like members are configured to be able to approach each other to pass through the mounting hole and then spring back away from each other so that the fixing buckle is fixed to the mounting hole via the mounting structure. The two second plate portions are configured to be able to move away from each other to allow the engine hood support rod to enter and then spring back towards each other to clamp the engine hood support rod.

[0006] According to one embodiment of the present invention, each first plate portion includes a first segment, a second segment, and a connecting segment connecting the first segment and the second segment, wherein the first segment and the second segment both bulge outward in a direction away from the other first plate portion relative to the connecting segment.

[0007] According to one embodiment of the present invention, the mounting hole is a rectangular hole, the width of the fixing buckle is adapted to the length of the mounting hole, the distance between each part of the two first plate portions when the fixing buckle is in a free state is greater than the width of the mounting hole, and the first distance defined by the mutually opposing outward protrusions of the two first portions is greater than the second distance defined by the mutually opposing outward protrusions of the two second portions.

[0008] According to one embodiment of the present invention, the first distance defined by the mutually opposing outward protrusions of the two first segments is 1.5-4 mm larger than the width of the mounting hole.

[0009] According to one embodiment of the present invention, the second distance defined by the mutually opposing protruding portions of the two second sections is 1-2 mm larger than the width of the mounting hole.

[0010] According to one embodiment of the present invention, when the fixing buckle is in a free state, the third distance defined by the outer sides of the two connecting segments that are opposite to each other is 0.2-0.5 mm larger than the width of the mounting hole.

[0011] According to one embodiment of the present invention, the extension length of each of the connecting segments is adapted to the thickness of the first bracket at the mounting hole.

[0012] According to one embodiment of the present invention, each of the second plate portions includes a third portion connected to the second portion, and the two third portions extend outward relative to each other to jointly define a receiving space sized to fit the engine hood strut.

[0013] According to one embodiment of the present invention, each second plate portion further includes a fourth section and a transition section, the two fourth sections being connected via the transition section to the end of the third section opposite to the second section and being far apart from each other in the direction opposite to the third section, the distance between the two transition sections being less than the diameter of the engine hood strut.

[0014] According to one embodiment of the present invention, the fixing buckle is integrally formed as a whole and has an outwardly flared cross-section.

[0015] According to one embodiment of the present invention, the fixing device further includes a second bracket, and the fixed end of the engine hood support rod is hinged to the second bracket.

[0016] According to another aspect of the present invention, a working machine is provided, which includes an engine hood support rod and a fixing device as described above.

[0017] The fixing buckle of this utility model, through two oppositely arranged plate-like members, can approach each other and pass through the mounting hole, and can also spring back to each other, so that the fixing buckle can be fixed into the mounting hole via the two first plates. This avoids the need for bolts for fixing buckles in the prior art. It only uses its own structure to install and fix the engine hood support rod. The structure is lightweight and saves on installation process and parts. Furthermore, it avoids the possibility of damage to the buckle due to excessive or excessive operating force, as is the case in the prior art. Attached Figure Description

Therefore, the following aspects, features, embodiments, and advantages are for illustrative purposes only and should not be construed as elements or limitations of the claims unless expressly set forth in the claims.

[0024] The terms "first" and "second" are used below to describe the elements of this application. These terms are used only to distinguish the individual elements and not to limit the nature, order, or number of these elements. The terms "comprising" and "having" are used to indicate an open-ended inclusion and mean that there may be additional elements / components besides those listed.

[0025] Figure 1 A fixing device according to one embodiment of the present invention is shown, which can be used to fix an engine hood support rod 1 to a side plate 2 on one side of the engine compartment of a working machine. Figure 1 As shown, the fixing device according to this embodiment may include a first bracket 3, a second bracket 4, and a fixing buckle 5 that is detachably fixed to the first bracket 3.

[0026] The first bracket 3 generally includes a strut support section and a side plate mounting section that are perpendicular to each other, such as... Figure 4 As shown. The strut support section is provided with mounting holes 31 for installing the fixing clips 5. The side plate mounting section is provided with two through holes 32, which allow the first bracket 3 to be installed on the side plate 2 by passing two bolts through the corresponding holes and through holes 32 on the side plate and tightening them with nuts. The fixing clips 5 are located in the mounting holes 31.

[0027] The second bracket 4 is fixed to the side plate 2 by welding and extends obliquely upward in the direction away from the first bracket 3, so that the through hole 41 provided on the second bracket 4 is not blocked by the side plate 2. In this embodiment, both the first bracket 3 and the second bracket 4 are provided on the side plate 2. In some other embodiments, the first bracket 3 and the second bracket 4 may also be provided on different components.

[0028] The engine hood support rod 1 may include a fixed end and a movable end, and its fixed end ( Figure 1 The upper right end of the hood support rod 1 is provided with a hook that passes through the through hole 41 on the second bracket 4, allowing the fixed end of the hood support rod 1 to be hinged to the second bracket 4. The hood support rod 1 as a whole can rotate relative to the second bracket 4 to be positioned in a supported position and a retracted position. When the hood support rod 1 is in the supported position, its movable end can abut against the hood, thereby supporting the hood and facilitating maintenance of equipment in the engine compartment. When the hood support rod 1 is in the retracted position, its movable end can be snapped onto the fixing buckle 5 and fixed to the first bracket 3 via the fixing buckle 5.

[0029] Figure 2 A specific example of the fixing clip 5 of this embodiment being installed into the mounting hole 31 is shown. For example... Figure 2As shown, the fixing buckle 5 may include a mounting structure 51 and a strut fixing structure 52. The mounting structure 51 may include two first plate portions 53 arranged opposite each other, and the strut fixing structure 52 may include two second plate portions 54 arranged opposite each other. The two second plate portions 54 are respectively connected to the corresponding first plate portions 53, thereby forming two plate-shaped members that are opposite each other and are each thin plate-shaped. The two plate-shaped members may be made of metal, plastic or other materials as a single piece, and have a certain degree of elasticity due to their extended length. In this way, the two plate-shaped members can move closer or further away from each other. When a force is applied to the two plate-shaped members to bring them closer together, the fixing buckle 5 can be inserted into the mounting hole 31. Then, when the applied force is released, the two plate-shaped members can spring back away from each other, so that the two first plate portions 53 abut against the hole wall of the mounting hole 31. Thus, the fixing buckle 5 can be fixed into the mounting hole 31 by the mounting structure 51. The hood support rod 1 is pressed between the two second plates 54, allowing the hood support rod 1 to push the two second plates 54 away from each other, thereby entering the receiving space between the two second plates 54. Then, the two second plates 54 can spring back closer to each other to clamp the hood support rod 1. In this embodiment, the description of plates and plates does not limit the shape of the cross-section of each component itself. For example, the first plate 53 and the plate-shaped member refer to a structure that is thin and plate-shaped in a broad sense, without limiting whether it is flat or corrugated.

[0030] In this embodiment, the fixing buckle 5 may further include a bent portion 55 connecting the two plate-shaped members to each other. The bent portion 55 is disposed at one end of the mounting structure 51 away from the support rod fixing structure 52, and is preferably integrally formed with the two plate-shaped members, for example, by bending or stamping a metal sheet. Figure 2 and Figure 3 As shown.

[0031] Optionally, the cross-section of the bend 55 can be either rounded or pointed. Setting the cross-section of the bend 54 to a rounded shape, i.e., the cross-section of the bend 55 having an arc shape, simplifies the manufacturing process. Setting the cross-section of the bend 55 to a pointed shape provides greater elastic force for the mutual springback of the two plate-like members, such as... Figure 2 and Figure 3 As shown. Of course, in practical applications, if the space occupied by the bent portion 55 is large after the fixing buckle 5 is installed on the first bracket 3, the cross-section of the bent portion 55 can also be a flat angle shape. The cross-section of the fixing buckle 5 is an outwardly flared trumpet shape, which can provide a larger springback space for the fixing buckle 5, especially the support rod fixing structure 52.

[0032] Figure 3 A perspective view of the fixing buckle 5 according to this embodiment is shown. Combined with... Figure 2 and Figure 3 As shown, each first plate portion 53 may include a first segment 531, a second segment 532, and a connecting segment 533. Two first plate portions 53 are arranged opposite to each other. Each first segment 531 protrudes outward in a direction away from the other first segment 531 to form its own first outward protrusion, and each second segment 532 also protrudes outward in a direction away from the other second segment 532 to form its own second outward protrusion. The connecting segment 533 connects the first segment 531 and the second segment 532. According to... Figure 3 As shown, in this embodiment, the two plate-shaped members are symmetrical with respect to the X-plane. The direction of each plate-shaped member facing the X-plane is called inward, and the direction away from the X-plane is called outward. An operator can squeeze the two plate-shaped members together by hand, causing them to move closer under external force. The strut fixing structure 52 and the second section 532 pass through the mounting hole 31 in sequence, and then the connecting section 533 is placed inside the mounting hole 31. Releasing the two plate-shaped members causes the two first plate sections 53 to spring back away from each other, and the fixing buckle 5 can be engaged with the mounting hole 31 of the first bracket 3 via the connecting section 533. The outward convex features of the first section 531 and the second section 532 prevent the connecting section 533 from detaching from the mounting hole 31.

[0033] refer to Figures 2 to 4 As shown, the mounting hole 31 can be a rectangular hole with a length of a and a width of b. The width D of the two plate-like members in the Y direction is adapted to (for example, slightly smaller than) the length a of the mounting hole 31, which facilitates the insertion of the fastener 5 into the mounting hole 31. When the fastener 5 is in a free state, the maximum distance defined between the portions of the two first plate portions 53 is greater than the width b of the mounting hole 41. For example, the opposing first protrusions of the two first portions 531 define a first distance L1. The first distance L1 is set to be greater than the width b of the mounting hole 31. Correspondingly, a second distance L2 is defined between the opposing second protrusions of the two second portions 532. The second distance L2 is also set to be greater than the width b of the mounting hole 31. This prevents the fastener 5 from slipping out of the mounting hole 31. Furthermore, the first distance L1 is greater than the second distance L2.

[0034] Optionally, the first spacing L1 is 1.5-4 mm larger than the width b of the mounting hole 31. This ensures that when the fixing buckle 5 is in the mounting state fixed to the first bracket 3, it can be effectively fixed into the mounting hole 31 and will not fall off the first bracket 3 when the engine hood support rod 1 is pulled out from the fixing buckle 5. In this embodiment, the first spacing L1 is preferably 3.6 mm larger than the width b of the mounting hole 31.

[0035] The second spacing L2 is 1-2 mm larger than the width b of the mounting hole 31. On the one hand, it allows for sufficient width between the protrusions of the two second sections 532 to keep the fixing buckle 5 in the mounting hole 31. On the other hand, it also facilitates the two second sections 532 that are brought close to each other by external force to pass through the mounting hole 31.

[0036] In this embodiment, the width b of the mounting hole 31 is 6mm, and the first spacing L1 and the second spacing L2 when the fixing buckle 5 is fixed into the mounting hole 31 are 8.2mm and 7.8mm, respectively.

[0037] Continue to refer to Figures 2 to 4 As shown, at the extreme position where the two plate-like members are close to each other, that is, when the ends of the two plate-like members facing away from each other are pinched together, the distance between the opposing second protrusions of the two second segments 532 is set to be less than or equal to the width b of the mounting hole 31. This facilitates the fastener 5 passing through the mounting hole 31. It is understood that since the first segment 531 does not need to pass through the mounting hole 31, the distance defined by the opposing first protrusions of the two first segments 531 at the extreme position where the two plate-like members are close to each other does not need to be considered.

[0038] In the above embodiments, when the connecting section 533 is fixed into the mounting hole 31 by the fixing buckle 5, the connecting section 533 can at least partially fit against the hole wall of the mounting hole 31, such as... Figure 2 As shown. In Figure 3 When the fixing buckle 5 is in a free state, a third gap L3 is defined between the opposite outer sides of the two connecting segments 533. This third gap L3 is also set to be larger than the width b of the mounting hole 31. Under the elastic force of the two plate-like members before the fixing buckle 5 returns to its free state, the connecting segments 533 elastically abut against the first bracket 3 within the mounting hole 31, thus securing the fixing buckle 5. Furthermore, the extension length H of the connecting segments 533 can be adapted to the thickness h of the strut support segment of the first bracket 3. This allows for axial positioning of the fixing buckle 5 within the mounting hole 31. Optionally, the third gap L3 is 0.2-0.5 mm larger than the width b of the mounting hole 31, ensuring that the two connecting segments 533 can elastically abut against the first bracket 3 after passing through the mounting hole 31. For example, if the width b of the mounting hole 31 is 6 mm, the third gap L3 of the fixing buckle 5 is 6.2 mm to 6.6 mm, preferably 6.4 mm. It is understandable that the first spacing L1, the second spacing L2, and the third spacing L3 are all at the position of the fixed buckle 5. Figure 3 The free state shown is limited to this.

[0039] refer to Figure 2 and Figure 3As shown, each second plate portion 54 may include a third portion 541 connected to the second portion 532. The two third portions 541 expand outwards relative to each other at their respective midpoints, thereby jointly defining a receiving space. In this embodiment, the cross-section of the hood support rod 1 is approximately circular, and the outwardly expanding portion of the third portion 541 has an arcuate surface that matches the local circumferential surface of the hood support rod 1. Therefore, after the hood support rod 1 enters between the two third portions 541, the two plate-like members spring back against each other, clamping the hood support rod 1 within the receiving space. For example, in this embodiment, the cross-section of the hood support rod 1 is a circle with a diameter of 8 mm. When the retaining clip 5 is in a free state, the diameter of the arcuate surface of the outwardly expanding portion of the third portion 541 can be slightly less than 8 mm. This slightly opens the two third portions 541 when the hood support rod 1 is within the receiving space, allowing the two third portions 541 to have a certain elastic force to clamp the hood support rod 1.

[0040] Optionally, each second plate portion 54 may further include a fourth portion 542 connected to the end of the third portion 541 that faces away from the second portion 532, such as Figure 3 As shown. The fourth segment 542 extends outward from the third segment 541 in a direction away from the second segment 532 (for example, at an angle of approximately 45° to the X-plane). By distancing the two fourth segments 542 from each other in a direction away from the third segment 541, it facilitates the entry of the hood support rod 1 into the receiving space. Even if the hood support rod 1 is offset from the position between the two third segments 541, it can be guided smoothly into the receiving space by the guide surface provided by the fourth segment 542.

[0041] Optionally, each second plate portion 54 may also include a transition section 543. Each fourth section 542 and the corresponding third section 541 are connected via the transition section 543, and the distance between the two transition sections 543 is less than the diameter of the hood support rod 1, thereby limiting the hood support rod 1 within the receiving space when the fixing device is in the installed state fixed into the mounting hole 31.

[0042] This utility model also provides a working machine that includes the above-mentioned fixing device.

[0043] Industrial applicability

[0044] The fixing device according to this invention is suitable for work machinery that requires support of the engine hood during maintenance. However, it should be understood that the fixing device according to this invention can also be used for other equipment that requires support of components, such as motor vehicles with engine hoods.

[0045] by Figures 1 to 4In the illustrated embodiment, during the assembly and fixing of the device, the second bracket 4 is welded to the side plate 2 of the working machinery, and the first bracket 3 is fixed to the side plate 2 by bolts and nuts. The two plate-shaped members are squeezed together until they are in a compressed extreme position, i.e., the two transition sections 543 are in abutting position. The strut fixing structure 52 and the two second sections 532 are then... Figure 2 The lower side extends upward through the mounting hole 31. When the two connecting sections 533 are inside the mounting hole 31, the two plate-shaped members are released, allowing the two first plate sections 53 to spring back against each other, thus abutting the connecting sections 533 against the wall of the mounting hole 31. The first sections 531 and the second sections 532 are positioned on opposite sides of the strut support section of the first bracket 3, thereby securing the fixing buckle 5 to the first bracket 3. This completes the assembly of the fixing device onto the side plate 2 of the working machinery.

[0046] The fixed end with a hook on the hood support rod 1 is hinged to the second bracket 4. That is, the hook on the hood support rod 1 passes through the through hole 41 on the second bracket 4, allowing the hood support rod 1 to extend along the extension direction of the side plate 2. When the hood support rod 1 needs to be placed in the storage position, the movable end of the hood support rod 1 can be placed between the two fourth sections 542 of the fixing buckle 5, and the hood support rod 1 can be pressed down so that it can enter the receiving space between the two third sections 541 through the guidance of the fourth sections 542. During this process, the two second plates 54 move away from each other. After the hood support rod 1 enters the receiving space, the two second plates 54 move closer to each other due to the rebound, and the hood support rod 1 is fixed to the fixing buckle 5 by the clamping of the two second plates 54.

[0047] As described above, the fixing buckle 5 of the fixing device according to this utility model can approach each other via its two oppositely arranged plate-like members, allowing the strut fixing structure 52 and the mounting structure 51 to pass through the mounting hole 31 in sequence. When the mounting structure 51 corresponds to the mounting hole 31, the two first plate portions 53 can spring back and be fixed into the mounting hole 31. This avoids the need for bolts for installation in the prior art fixing buckle, and only uses its own structure to install and fix the engine hood strut 1. The structure is lightweight and saves on installation process and installation parts. Furthermore, it avoids the situation in the prior art where the buckle may be damaged due to excessive or excessive operating force.

[0048] Various modifications and variations can be made to the embodiments disclosed above without departing from the scope or spirit of this invention. Other embodiments of this invention will be apparent to those skilled in the art based on the practice of this invention disclosed in this specification. This specification and the examples disclosed herein should be considered illustrative only, and the true scope of this invention is defined by the appended claims and their equivalents.
