Description

Technical Field

[0001] The invention relates to the technical field of loader parts, and in particular to a base self-locking structure of a loader control box. Background Art

[0002] The existing loader control box installation method is mostly flip installation, specifically Figure 1 As shown, the control box 3 is connected to the mounting plate 2 via a hinge. A spring support 1 is provided on one side of the hinge. The upper end of the spring support 1 is hinged to the control box 3, and the lower end is hinged to the mounting plate 2. A clamping member 8 is rotatably connected to one side of the control box 3. A hook is provided at the lower part of the clamping member 8. A corresponding snap ring is provided on the mounting plate 2. The hook and the snap ring are detachably connected. At this time, the control box 3 is in a locked state. When the operator presses down on the control box 3 and swings the clamping member 8, the hook separates from the snap ring. The control box 3 is quickly flipped under the action of the spring support 1, and the control box 3 is released and the locked state is released. Since there is no corresponding buffer mechanism when the control box 3 is quickly flipped, the quickly flipped control box 3 will be subjected to a large impact force at the moment of emergency stop, which can easily cause the connecting parts and even the internal parts of the control box 3 to be subjected to large vibrations, and even the parts may become loose, affecting the service life of the control box 3.

[0003] Furthermore, since the clip 8 is rotatably mounted, its position can be freely moved after the control box 3 is released. When the control box 3 needs to be flipped over and locked, the operator needs to manually adjust the position of the clip 8 to ensure that the hook of the clip 8 is connected to the snap ring. Since the hook and snap ring at the bottom of the clip 8 are located below the control box 3, the operator cannot see the hook and snap ring during the connection and locking process. In addition, the small opening of the hook makes it difficult to connect with the snap ring, resulting in the problem of the clip 8 not locking smoothly, which requires a long time to debug.

[0030] Example

[0031] like Figure 2-6 As shown, a self-locking structure for the base of a loader control box comprises a control box 3, a mounting plate 2, a spring support 1, and a clamping member 8. The bottom surface of the control box 3 is hinged to the mounting plate 2 via a hinge. The spring support 1 is located on one side of the hinge, with its upper end hinged to the control box 3 and its lower end hinged to the mounting plate 2. The clamping member 8 is hinged to the side of the control box 3 away from the hinge. A telescopic rod 1-4 is hinged to the bottom surface of the control box 3. The hinge is located between the spring support 1 and the telescopic rod 1-4. The telescopic rod 1-4 is connected to a damping rod 5, the bottom of which is hinged to the mounting plate 2.

[0032] It should be noted that the bottom of the existing control box 3 is provided with a cavity, and the mounting plate 2 is provided with a slot, and the hinged ends of the spring support 1 and the damping rod 5 are installed in the corresponding cavity or slot, so Figure 1 and Figure 2 In the schematic diagram shown, the hinged ends of the spring support 1 and the damping rod 5 are hidden and cannot be seen.

[0033] The damping rod 5 provides a strong cushioning effect, providing protection during the tilting of the control box 3. In this embodiment, when the spring support 1 reaches two-thirds of its total extended length, the telescopic rod 1 4 reaches its contraction limit and cannot further retract. Specifically, when the spring support 1 reaches less than two-thirds of its total extended length, the contraction of the telescopic rod 1 4 offsets the displacement of its end portion during the tilting of the control box 3. Therefore, in this tilted state, the damping rod 5 neither hinders the tilting of the control box 3 nor contracts due to the forces acting on it. When the spring support 1 reaches more than two-thirds of its total extended length, the telescopic rod 1 4 is already in its ultimate compression state. Therefore, the damping rod 5 is squeezed and contracted by the tilting force of the control box 3. Due to this interaction of forces, the damping force generated by the contraction of the damping rod 5 also acts on the control box 3, slowing its tilting speed and preventing the excessive impact force generated when the control box 3 stops due to excessive tilting speed, thus effectively protecting the control box 3.

[0034] A connecting rod 7 is provided on the side of the clamping member 8 away from the control box 3, and a card slot 15 is opened on one side of the lower end of the connecting rod 7. The card slot 15 is located on the side away from the control box 3, and the mounting plate 2 is provided with a rotation locking structure 11 and a latch linkage structure 10 for locking the card slot 15.

[0035] The rotation locking structure 11 includes a mounting seat 111, a mounting seat 2 112, a V-shaped clamp 113, a locking plate 114, and a spring 115. Both the mounting seat 111 and the mounting seat 2 112 are fixedly connected to the mounting plate 2 via a connecting plate 116. A plug-in gap 117 having a width greater than the width of the connecting rod 7 is provided between the mounting seat 111 and the mounting seat 2 to enable plugging of the connecting rod 7 and prevent interference between the connecting rod 7 and the mounting seat. In addition, to further prevent interference between the connecting rod 7 and the mounting seat, the bottom of the connecting rod of this embodiment is configured as an arc shape. The locking plate 114 is slidably mounted in the plug-in gap 117 and can move up and down. The top of the spring 115 is connected to the locking plate 114, and the bottom is fixedly connected to the connecting plate 116. A groove 119 is provided on one side of the mounting seat 111, and the V-shaped clamp 113 is installed in the groove 119 by rotating the shaft. A torsion spring is provided on the shaft, and the torsion force generated by the torsion spring can move the V-shaped clamp 113 toward the groove 119 away from the side of the mounting seat 2 112.

[0036] A first positioning claw 120 and a second positioning claw 121 are respectively provided at each end of the V-shaped clamp 113. A locking plate 114 is positioned between the first and second positioning claws 120 and 121. A slot 118 is provided on the side of the locking plate 114 facing away from the V-shaped clamp 113. A limit pin 122 is provided below the second positioning claw 121 and is connected to the connecting plate 116. When the connecting rod 7, through the locking plate 114, drives the second positioning claw 121 into contact with the limit pin 122, the first positioning claw 120 precisely engages the slot 15. The limit pin 122 is used to limit the rotational position of the V-shaped clamp 113 and the downward displacement of the connecting rod 7 and the locking plate 114.

[0037] When the control box 3 needs to be locked, the control box 3 is pressed down, the bottom of the connecting rod 7 is inserted into the insertion gap 117, and the locking plate 114 is pushed downward, driving the V-shaped clamp 113 to rotate, so that the positioning claw 120 is inserted into the card slot 15, and the inner side of the positioning claw 120 is in contact with the bottom of the card slot 15 to form a buckling action on the connecting rod 7. When the control box 3 is released, the V-shaped clamp 113 will move forward under the action of the torsion spring. Figure 5 The counterclockwise rotation in the middle and the sidewall contact of the slot 119 away from the mounting base 2 112. In addition, the locking plate 114 will rise and reset under the restoring force of the spring 115, but the positioning claw 2 121 contacts with the locking plate 114 all the time.

[0038] The latch linkage mechanism 10 is mounted within the second mounting base 112 and includes a latch rod 103, a driven pressure rod 102 for driving the latch rod 103 horizontally, and an active pressure rod 101 for driving the driven pressure rod 102 vertically. The second mounting base 112 includes a vertical mounting slot 105 and a horizontal mounting slot 206. The top of the first mounting slot 105 extends through the top of the second mounting base 112. One end of the second mounting slot 106 connects to the middle of the first mounting slot 105, and the other end extends through the side of the second mounting base 112. When the second mounting slot 106 is aligned with the slot 118, the second positioning claw 121 contacts the stop pin 122.

[0039] The driven pressure rod 102 is movably inserted in the installation groove 105 and is connected to an elastic component. The latch rod 103 is movably installed in the installation groove 2 106 and is connected to an elastic structure. The driven pressure rod 102 and the latch rod 103 are both square rods, and the bottom end of the driven pressure rod 102 and the end of the latch rod 103 facing the installation groove 105 are both provided with an inclined cross-section 108, so that the latch rod 103 can move toward the slot 118 under the squeezing action of the driven pressure rod 102 and finally be inserted into the slot 118.

[0040] When the elastic assembly is in its natural state, the driven pressure rod 102 is spaced apart from the latch rod 103. At this point, the elastic structure is in its natural state, and the end of the latch rod 103, away from the first mounting groove 105, is perfectly positioned within the second mounting seat 112. The active pressure rod 101 is positioned above the driven pressure rod 102. When the driven pressure rod 102 moves downward, it compresses the elastic assembly and pushes the latch rod 103 horizontally, compressing the elastic structure.

[0041] Specifically, the elastic component includes a positioning frame 1001, a first limiting piece 1002, and a second spring 1003. The positioning frame 1001 is fixedly mounted on the top of the second mounting seat 112. The driven pressure rod 102 movably penetrates the positioning frame 1001. The first limiting piece 1002 is fixedly mounted on the driven pressure rod 102 and located within the positioning frame 1001. The second spring 1003 is movably mounted on the driven pressure rod 102 and located between the first limiting piece 1002 and the second mounting seat 112. The elastic structure includes a positioning slot 1004, a second limiting piece 1005, a limiting block 1006, and a third spring 1007. The limiting block 1006 is located on the side of the second mounting seat 112 facing the insertion gap 117. The second mounting slot 106 extends through the limiting block 1006. The positioning slot 1004 is located between the limiting block 1006 and the first mounting slot 105. The second limiting piece 1005 is fixedly mounted on the latch rod 103 and located within the positioning slot 1004. The third spring 1007 is movably mounted on the latch rod 103 and located between the second limiting piece 1005 and the limiting block 1006. Springs 1003 and 1007 can be made of springs with high spring rates to ensure a strong elastic force during reset and avoid reset problems.

[0042] The connecting rod 7 is provided with a plug-in slot, in which a movable rod 9 is movably plugged. The top of the movable rod 9 extends above the connecting rod 7 and is connected to a rebound self-locking assembly 6. The rebound self-locking assembly 6 includes a rebounder 61 and a pressing plate 62. The top of the rebounder 61 is fixedly connected to the top of the movable rod 9 via the pressing plate 62. The rebounder 61 is a prior art. When the rebounder 61 self-locks the piston rod inside it, the length of the movable rod 9 extending from the connecting rod 7 is the shortest, and the movable rod 9 is in the locking gear. When the rebounder 61 does not self-lock the piston rod inside it, the length of the movable rod 9 extending from the connecting rod 7 is the longest, and the movable rod 9 is in the reset gear.

[0043] The rebound self-locking assembly 6 also includes a protective frame, which includes a frame body 63 and a flip cover 64. The frame body 63 is fixedly connected to the connecting rod 7. The rebounder 61 and the pressing plate 62 are both located within the frame body 63. One side of the flip cover 64 is hinged to the frame body 63, and the opposite side is detachably connected to the frame body 63 via two mutually attracted magnet strips 65. The protective isolation function of the protective frame prevents accidental pressing of the pressing plate 62.

[0044] A strip-shaped through-slot 104 is provided at the lower portion of the connecting rod 7. One end of the active pressure rod 101, away from the passive pressure rod 102, movably passes through the strip-shaped through-slot 104 and is fixedly connected to the movable rod 9, so that the movement of the movable rod 9 can drive the movement of the active pressure rod 101. Specifically, a pressure block 107 is provided on the top of the passive pressure rod 102. The pressure block 107 is in contact with and connected to the active pressure rod 101. When the active pressure rod 101 descends, the linkage between the pressure block 107 and the active pressure rod 101 drives the passive pressure rod 102 to descend.

[0045] When the control box 3 needs to be locked, the operator presses the control box 3 downward to insert the connecting rod 7 into the rotation locking structure 11, and the rotation locking structure 11 engages the connecting rod 7. After the rotation locking structure 11 has engaged the connecting rod 7, the movable rod 9 is pushed to the locking position, and the latch rod 103 of the latch linkage structure 10 is inserted into the slot 118 of the locking plate 114 to lock the current operating state of the rotation locking structure 11. As a result, the operating states of the latch linkage structure 10 and the rotation locking structure 11 are locked at this time, and the control box 3 is locked.

[0046] When the control box 3 needs to be released, the movable rod 9 is driven to the reset position, the driven pressure rod 102 is reset and moved upward, the latch rod 103 is reset and separated from the slot 118, and the rotation locking structure 11 releases the connection with the connecting rod 7. The control box 3 is flipped under the driving action of the extension force of the spring support 1, and the connecting rod 7 is separated from the rotation locking structure 11, thereby realizing the release of the control box 3 and causing it to flip under the driving action of the spring support 1.

[0047] Furthermore, a connecting seat 12 is pivotally mounted on one side of both the connector 8 and the control box 3. A second telescopic rod 13 is hingedly mounted between the two connecting seats 12. A spring 4 14 is sleeved around the outer side of the second telescopic rod 13. The spring 4 14 and the second telescopic rod 13 are designed to prevent the connector 8 from rotating freely, ensuring convenient locking of the control box 3. The bottom of the locking plate 114 is connected to the connecting plate 116 via a vertically mounted third telescopic rod 123. A spring 115 sleeved around the outer side of the third telescopic rod 123 ensures the stability of the locking plate 114 during its vertical movement.

[0048] The working principle of the present invention is as follows: When the control box 3 needs to be locked, the control box 3 is first turned over so that the connecting rod 7 is inserted into the insertion gap 117. During the insertion process, the connecting rod 7 will press against the locking plate 114 and descend, and the spring 115 will contract at this time. Since the locking plate 114 is always in contact with the positioning claw 2 121 of the V-shaped clamp 113, the descent of the locking plate 114 will drive the V-shaped clamp 113 to rotate. When the V-shaped clamp 113 contacts the limiting pin 122, the continued downward force on the control box 3 is stopped. At this time, the positioning claw 1 120 will be inserted into the card slot 15, forming a buckling action on the connecting rod 7, and the slot 118 is directly opposite the latch rod 103. Next, the flip cover 64 is opened and the pressing plate 62 is pressed downward, causing the movable rod 9 to move downward. Driven by the movable rod 9, the active pressure rod 101, the pressure block 107, and the driven pressure rod 102 also move downward. When the driven pressure rod 102 contacts the latch rod 103, it pushes the latch rod 103 into the slot 118, thereby locking the locking plate 114. When the rebounder 61 self-locks its piston rod, the control box 3 is locked. To release the control box 3, the flip cover 64 is opened and the pressing plate 62 is pressed downward to trigger the rebounder 61. The rebounding action of the rebounder 61 drives the movable rod 9 upward. Simultaneously, under the action of the spring forces of springs 2 1003 and 3 1007, the driven pressure rod 102 and the latch rod 103 are reset in sequence. After resetting, the latch rod 103 disengages from the slot 118, and the locking plate 114 is no longer locked. Under the action of the spring support 1, the control box 3 is turned over, thereby driving the connecting rod 7 to turn over and disengage it from the insertion gap 117, and the V-shaped clamp 113 and the locking plate 114 are also reset in sequence.

[0049] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
