[0027] A sliding limit structure with a detachable slide rail, as Figure 1 shown, includes an inner rail 1, a middle rail 2 and an outer rail 3 that are slidably mated.

[0028] As Figure 1 shown, the inner rail 1 includes a movable bar 11, a toggle block 12 and a rotating block 13. The movable bar 11 is slidably connected in the length direction of the inner rail 1, and a tension spring is installed between the movable bar 11 and the inner rail 1, which is used to drive the movable bar 11 to reset.

[0029] As Figure 1 shown, the toggle block 12 is rotatably connected to the middle of the inner rail 1, and the rotating block 13 is rotatably connected to the toggle block 12, and the two are rotatably connected to the same rivet.

[0030] As Figure 2As shown, the toggle block 12 is provided with a first bridge-shaped portion 121 and a second bridge-shaped portion 122, which are symmetrically arranged about the center of the toggle block 12, and the first bridge-shaped portion 121 and the second bridge-shaped portion 122 form an arched space on the toggle block 12. A bending portion 123 is provided at one end of the toggle block 12, and when unlocking, the toggle block 12 is driven to rotate by pressing the bending portion 123. The end of the toggle block 12 away from the bending portion 123 is provided with a first contact wall 125 and a second contact wall 126, the second contact wall 126 is located at the edge of the second bridge-shaped portion 122, the second contact wall 126 is in a hook shape, the first contact wall 125 is provided as an inclined surface, and the first contact wall 125 is located outside the second contact wall 126.

[0031] Combination Figure 1 and Figure 2 As shown, a resilient member is installed on the toggle block 12, and the resilient member is a torsion spring 14. The toggle block 12 is provided with a torsion spring slot 124, which provides an installation position for the torsion spring 14. The torsion spring 14 is located on one side of the toggle block 12, and will be reset by the elastic force of the torsion spring 14 when there is no loss of external force. The resilient member can also be replaced with a spring sheet or a spring sheet according to the needs of different types of slide rails.

[0032] Combination Figure 1 and Figure 3 As shown, the rotating block 13 is provided with a bent first step portion 131 and a second step portion 132. When the inner rail 1 and the middle rail 2 are in a closed state, the first step portion 131 and the second step portion 132 are embedded in the space formed by the first bridge-shaped portion 121 and the second bridge-shaped portion 122, so as to realize the engagement between the rotating block 13 and the toggle block 12. A resilient member is installed on the rotating block 13, and the resilient member is a second torsion spring 15. The second torsion spring 15 is arranged on the rotating block 13, and the second torsion spring 15 drives the rotating block 13 to rotate and reset.

[0033] like Figure 1 As shown, a locking plate 211 is provided on the inner locking block 21, and the locking plate 211 is detachably connected to the inner locking block 21 by screws. The locking plate 211 is bent inwardly. When the inner rail 1 is pulled out to the limit, the second contact wall 126 and the second contact wall 126 of the locking plate 211 are engaged. When the inner rail 1 is locked, the locking plate 211 and the rotating block 13 are engaged.

[0034] Specific working process:

[0035] Combination Figure 1 and Figure 4As shown, when the inner rail 1 needs to be disassembled, the inner rail 1 is pulled outwards to the extreme position at this time, and the bent portion 123 is toggled, driving the toggle block 12 to start rotating around the rivet, so that the second contact wall 126 of the toggle block 12 is separated from the locking plate 211 of the inner locking block 21. At this time, the inner rail 1 can be pulled outwards until the middle rail 2 is removed and separated. When the inner rail 1 is reinstalled, the first contact wall 125 of the toggle block 12 contacts the inner locking block 21. Since the first contact wall 125 is an inclined surface, it drives the toggle block 12 to rotate around the rivet. Then the inner rail 1 continues to be inserted, and the toggle block 12 is reset under the action of the first torsion spring 14. At this time, the inner locking block 21 is clamped in the gap formed by the second contact wall 126 of the toggle block 12 and the rotating block 13. At this time, the inner rail 1 and the middle rail 2 are in a locked state.

[0036] Combined with Figure 1 and Figure 5 As shown, when the slide rail needs to be closed, the end of the movable bar 11 is pressed, and the movable bar 11 moves inwards along the length direction of the slide rail. The movable bar 11 presses the rotating block 13, and the rotating block 13 rotates around the rivet and disengages from the inner locking block 21. The inner rail 1 can continue to move inwards. After the unlocking is completed, the movable bar 11 is released and reset under the action of the elastic force, and the rotating block 13 is reset under the action of the second torsion spring 15. At this time, the toggle block 12 and the rotating block 13 fit together, and the two stepped portions of the rotating block 13 are inserted into the space formed by the first bridge-shaped portion 121 and the second bridge-shaped portion 122 of the toggle block 12. The first bridge-shaped portion 121 presses the movable bar 11 and the rotating block 13 to ensure the normal operation when the components move relative to each other.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0038] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
