[0054] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0055] This embodiment provides a folding key with lighting function, including a straight-cylindrical holding tube 10, a key assembly 20 and a lighting assembly 30 installed at one axial end of the holding tube 10; preferably, see Figures 1 to 4 The holding tube 10 is cylindrical, and the holding tube 10 has a key compartment 112;

[0056] The key assembly 20 includes a mounting rod 21 and a key 22, and the number of the key 22 is at least one; at least one key 22 is integrated with the lighting assembly 30 on the holding tube 10, which is easy to carry and convenient to use the lighting assembly 30 for auxiliary maintenance in dark places. The lighting assembly 30 can provide direct lighting or indirect lighting during the auxiliary maintenance process, that is, the lighting assembly 30 directly illuminates the maintenance area or the lighting assembly 30 illuminates the surrounding area of ​​the maintenance area to improve the brightness of the maintenance area through physical phenomena such as reflection or diffuse reflection.

[0057] The mounting rod 21 includes a first end 2101 and a second end 2102. The first end 2101 is rotatably connected to the holding tube 10. The key 22 is disposed on the mounting rod 21. When the first end 2101 rotates relative to the holding tube 10, the second end 2102 moves between a first position and a second position.

[0058] When the second end 2102 is located at the first position, the second end 2102 and the key 22 are located in the key chamber 112, which is the retracted state of the folding key. The second end 2102 and the key 22 are both retracted into the key chamber 112. At this time, the key assembly 20 is retracted into the holding tube 10, which reduces the volume and space occupied by the folding key, making it easier to carry.

[0059] When the second end 2102 is in the second position, the second end 2102 and at least one key 22 are located outside the key compartment 112, and the portion where the key 22 outside the key compartment 112 cooperates with the lock core is exposed outside the mounting rod 21. This is the use state of the folding key. When in use, the key 22 is used to cooperate with the corresponding lock core to open the lock, which is convenient for maintenance work.

[0060] In some preferred embodiments, the key 22 is sleeved on the mounting rod 21 along the axial direction of the mounting rod 21 , and the structure is simple, and a variety of different types of keys (at least commonly used keys) can be sleeved on the mounting rod 21 .

[0061] In some preferred embodiments, the key 22 includes a key head and a connecting portion connected to each other at one axial end, the key head has a through slot along the axial direction, the connecting portion has a sleeve hole connected to the through slot along the axial direction, the outer diameter of the through slot is not less than the outer diameter of the sleeve hole; the inner wall of the sleeve hole matches the outer wall of the mounting rod;

[0062] The key 22 includes a key head 221 and a connecting portion 222 connected to each other at one axial end. The key head 221 has a through slot along the axial direction, and the connecting portion 222 has a sleeve hole 224 connected to the through slot along the axial direction. The outer diameter of the through slot is not less than the outer diameter of the sleeve hole 224, so that the key 22 can be conveniently sleeved on the mounting rod 21. The inner wall of the sleeve hole 224 matches the outer wall of the mounting rod 21.

[0063] In some preferred embodiments, a key head 221 is provided at each end of the connecting portion 222, and two different types of key heads 221 are integrated at the two ends of the same connecting portion 222, thereby reducing the number of keys 22 and further reducing the volume of the folding key described in the utility model, making it more convenient to carry.

[0064] See also Figure 2 , 6, 7, 8, the through slot of the key head 221 is the part that cooperates with the lock core. The key heads 221 commonly seen on trains are inner octagonal slots and inner square slots, and corresponding key heads 221 can be made according to needs; preferably, the outer side surface or end surface of the key head 221 is engraved with a model number for convenient and quick replacement; when the second end 2102 is in the second position: if only one key 22 is sleeved on the mounting rod 21, the key head 221 of the key 22 is exposed outside the second end 2102 of the mounting rod 21 for unlocking; if several keys 22 are sleeved on the mounting rod 21, the key head 221 of the key 22 at the outermost end near the second end 2102 is exposed outside the second end 2102 of the mounting rod 21 for unlocking;

[0065] Those skilled in the art will appreciate that, when unlocking the lock, the key head 22 must first be inserted into the lock core, that is, the key head 221 must be inserted into the lock core along the axial direction to match the lock core. During this process, if the key 22 or the key head 221 and the mounting rod 21 move relative to each other along the axial direction, it will be difficult for the key head 221 to match the lock core or the matching will fail. When the key head 221 is inserted into the lock core and the matching is completed, the unlocking action can be performed. Usually, the key 22 must be turned to drive the lock core to rotate. During this process, if the key 22 or the key head 221 and the mounting rod 21 rotate relative to each other along the circumferential direction of the mounting rod 21, it will cause the unlocking to fail. Therefore, it is necessary to rotate the key 22 and the mounting rod 2 1: the cooperation between the key head 221 and the lock core includes the process of the key head 221 being inserted into the lock core and the process of the key head 221 driving the lock core to rotate and realize unlocking. At least when the key head 221 is inserted into the lock core, the second limiting structure limits the movement of the key 22 along the axial direction of the mounting rod 21; and at least when the key head 221 drives the lock core to rotate, the second limiting structure limits the rotation of the key 22 along the circumference of the mounting rod 21; if only one key 22 is sleeved on the mounting rod 21, the key 22 is limited by the second limiting structure. When multiple keys 22 are sleeved on the mounting rod 21, at least the key at the outermost end is limited by the second limiting structure.

[0066] A second limiting hole 223 is formed on the side wall of the sleeve hole 224, and a second spring pin 24 matching the second limiting hole 223 is provided on the mounting rod 21. Figure 3 , that is, the second limiting structure includes a second spring pin 24 arranged on the mounting rod 21, and a second limiting hole 223 opened on the side wall of the sleeve hole 224, and the structure is simple;

[0067] In some preferred embodiments, the cross section of the matching portion of the mounting rod 21 and the key 22 is a non-circular cross section, such as a triangle, rectangle, octagon, ellipse, flower shape, etc., to prevent the key 22 and the mounting rod 21 from rotating along the circumferential direction of the mounting rod 21 during the unlocking action. Preferably, see Figure 2The cross section of the portion where the mounting rod 21 and the key 22 match is a regular polygon, preferably a square; the cross section of the portion where the mounting rod 21 and the key 22 match is a square, and a second spring pin 24 is provided on one side of the portion where the mounting rod 21 and the key 22 are sleeved, and the cross section of the corresponding sleeve hole 224 is a square, see also Figure 2 , 6 , 7, 8, a second limiting hole 223 is respectively provided on the four side walls of the sleeve hole 224. When the key 22 is sleeved on the mounting rod 21, any side wall of the sleeve hole 224 corresponds to the side where the second spring pin 24 is located, which facilitates installation and improves installation efficiency; further, the second limiting hole 223 penetrates to the outer surface of the connecting portion 222, and the matching angle between the sleeve hole 223 and the mounting rod 21 can be more intuitively distinguished during installation, further improving installation efficiency;

[0068] Those skilled in the art will know that during the use of the key, it is usually necessary to limit the key head 221 circumferentially so that the key head 221 can drive the lock core to rotate circumferentially. This circumferential limit is achieved through the cooperation of the sleeve hole 224 and the sleeve rod 211. During the cooperation between the key 22 and the lock core, the key head 221 needs to be axially limited. In addition, some keys 22 also need to apply axial pressure during the unlocking process and the key head 221 also needs to be axially limited. The second limiting hole 223 cooperates with the second spring pin 24 to limit the key head 221 axially when the axial force is small. However, when the axial force is large, the cooperation relationship between the second limiting hole 223 and the second spring pin 24 will be released. If the key head 221 is only limited axially by the cooperation of the second limiting hole 223 and the second spring pin 24, the unlocking failure may occur. To solve this problem, see Figure 3 , 5 In some preferred embodiments, the mounting rod 21 includes a sleeve rod 211 and a mounting head 212 fixed at one axial end of the sleeve rod 211. The sleeve rod 211 is a portion where the mounting rod 21 and the key 22 are sleeved together. The mounting head 212 is used to achieve connection with the gripping tube 10. The outer diameter of the mounting head 212 is greater than the outer diameter of the sleeve rod 211. The number of the second spring pin 24 is one. The second spring pin 24 is located on a side of the end of the sleeve rod 211 away from the mounting head 212. When a plurality of keys 22 are sleeved on the sleeve rod 211, adjacent keys 2 2, the second limiting hole 223 on the key 22 at the outermost end cooperates with the second spring pin 24, and the key 22 at the innermost end presses against the mounting head 212, that is, the second limiting hole 223 cooperates with the second spring pin 24 and is mainly used to limit the slipping of several keys 22. When the key head 221 at the outermost end applies pressure to the lock cylinder, since several keys 22 press against each other and the key 22 at the innermost end presses against the mounting head 212, the key head 221 at the outermost end can be effectively supported during the pressure application process, thereby ensuring successful unlocking.

[0069] In some preferred embodiments, when the second end 2102 is located at the second position, the angle between the axis of the mounting rod 21 and the axis of the holding tube 10 is in the range of 90°-120°, preferably 90°, that is, the holding tube 10, the mounting rod 21 and the key head 221 used for unlocking are in the form of an L-shaped wrench, which facilitates the unlocking personnel to apply force and improves the unlocking efficiency.

[0070] In some preferred embodiments, the holding tube 10 includes an open end surface away from the lighting assembly 30, and a notch is provided in the wall of the holding tube 10. Along the axial direction of the holding tube 10, the notch includes a third end 1101 and a fourth end 1102, and the third end 1101 is connected to the open end surface; see Figure 4 The holding tube 10 includes a tube body 11, a first connecting portion 12 for connecting to the lighting assembly 30, and a second connecting portion 13 for connecting to the key assembly, the second connecting portion passes through the corresponding end surface of the tube body 11; a first opening 111 is provided on one side of the tube body 11, and the part of the tube body 11 located in the first opening 111 is the key chamber 112, when the second end 2102 is located in the first position, the mounting rod 21 and the key 22 are located in the holding tube 10, that is, at this time, the key 22 is located in the key chamber 112; a second opening 131 is provided on one side of the second connecting portion 13, the first opening 111 is connected to the second opening 131 to form a gap, and the second opening 131 is the third end 1101;

[0071] The first end 2101 of the mounting rod 21 is rotatably connected to the third end 1101, and the rotation axis 135 is perpendicular to the axis of the holding tube 10. For easy installation, a U-shaped block 132 is provided in the second connecting portion 13. Preferably, the U-shaped block 132 is welded to the inner wall of the second connecting portion 13, and the open end of the U-shaped block 132 faces the second opening 131. The first end 2101 of the mounting rod 21 is rotatably connected to the two side walls of the U-shaped block 132 via the rotation axis 135. The rotation axis 135 is rotatably matched with the two side walls of the U-shaped block 132. The second connecting portion 13 is provided with first shaft holes 134 at both sides of the second opening 131, which is convenient for disassembling and assembling the rotation axis 135. Figure 5 The mounting head 212 has a second shaft hole 213, the middle of the rotating shaft 135 passes through the second shaft hole 213, and both ends of the rotating shaft 135 are respectively rotatably matched with the two side walls of the U-shaped block 132;

[0072] When the first end 2101 of the mounting rod 21 rotates along the rotation axis 135, the second end 2102 of the mounting rod 21 passes through the notch and moves between the first position and the second position;

[0073] When the second end 2102 of the mounting rod 21 is located at the first position, the outer contour line of the key assembly 20 projected along the axis direction of the holding tube 10 does not exceed the outer contour line of the holding tube 10. Preferably, the maximum outer diameter of the folding key as a whole is 22 mm, that is, the outer diameter of the holding tube 10 is 22 mm. When the mounting rod 21 and the key 22 are both received in the holding tube 10, the folding key as a whole is in a cylindrical shape, small in size and beautiful in appearance.

[0074] The distance between the fourth end 1102 and the rotation axis is greater than the distance between the outer end surface of the outermost key 22 and the rotation axis, so as to prevent the mounting rod 21 from interfering with the notch when rotating along the rotation axis 135. Figure 3 , 4 The fourth end 1102 has an arc transition, which makes the appearance smooth and beautiful and facilitates applying force at the second end 2102 to drive the mounting rod 21 to rotate along the rotation axis 135.

[0075] In some preferred embodiments, a first limiting structure is provided between the mounting rod 21 and the gripping tube 10, and the first limiting structure limits the relative rotation between the mounting rod 21 and the gripping tube 10. Figure 4 A first limiting mounting hole 214 is provided on one side of the mounting head 212, the axis of the first limiting mounting hole 214 is parallel to the axis of the second axial hole 213, and a first spring pin 23 is arranged in the first limiting mounting hole 214; a first limiting hole 133 is provided on one side wall of the U-shaped block 132, and when the second end 2102 is located at the first position, the first spring pin 23 cooperates with the first limiting hole 133, so as to prevent the mounting rod 21 from driving the key 22 to rotate out of the holding tube 10 by itself when the mounting rod 21 is in the retracted state, and a force is applied to the mounting rod 21 so that the first spring pin 23 When the first spring pin 23 is contracted and the first spring pin 23 is separated from the matching relationship with the first position-limiting mounting hole 213, the restriction of the mounting rod 21 is released, that is, the mounting rod 21 can rotate along the rotating shaft 135, and the second end 2102 moves between the first position and the second position. In the process of the mounting rod 21 rotating, the first spring pin 23 abuts against the side wall corresponding to the U-shaped block 132. When the second end 2102 returns to the first position, the first spring pin 23 is matched with the first position-limiting mounting hole 213 again, and the rotation of the mounting rod 21 is restricted again.

[0076] In some preferred embodiments, when the second end 2102 is located at the first position, the surface of the mounting head 212 abutting against the closed end of the U-shaped block is a first plane. Figure 3 The left side of the mounting head 212 is the second plane 218 of the side of the mounting head 212 away from the sleeve rod 211. The second plane 218 is shown in FIG. Figure 3The bottom surface of the mounting head 212 is formed in the middle. When the second end 2102 is located at the second position, that is, in the use state, the second plane 218 abuts against the closed end of the U-shaped block 132, and an arc surface 216 is provided between the first plane and the second plane 218 to facilitate the mounting rod 21 to rotate along the rotation axis 135. When the second end 2102 is rotated from the first position to the second position, the same force is continuously applied to try to make the mounting rod 21 continue to rotate along the rotation axis 135. Since the second plane 218 abuts against the closed end of the U-shaped block 132, and the other side surface ( Figure 3 There is no arc transition surface between the other side surface (the right side surface of the middle mounting head 212) and the second plane 218, so the action of continuing to rotate along the rotation axis 135 cannot occur, that is, when the second end 2102 is in the second position, it can only stay in the second position or move back to the first position.

[0077] In some preferred embodiments, the end surface of the second connecting portion 13 is provided with a first chamfer 136. Figure 3 Correspondingly, the second chamfer 217 is provided on the mounting head 212. Figure 5 When the second end 2102 is located at the first position, the first chamfer 136 and the second chamfer 217 are connected as a whole. Figure 1 .

[0078] In some preferred embodiments, a missing portion 219 is provided on the surface of the mounting head 212 opposite to the first plane, and the missing portion 219 is away from the second plane 218, see Figure 5 When the second end 2102 is located at the first position and the mounting rod 21 needs to be rotated, in addition to applying force to the third end 1101, force can also be applied to the mounting head 212 at the missing portion 219 to cause the mounting rod 21 to rotate along the rotating axis 135, which is convenient for one-handed operation, flexible to use, easy to operate, and further improves work efficiency.

[0079] In some preferred embodiments, a process groove 113 is opened on the side wall of the holding tube 10, and the bottom of the process groove 113 is flat, which is convenient for processing logos, names, etc. in the process groove 113.
