[0032] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0033] Please refer to Figure 1 In some embodiments, the buckle device 1000 includes a base 1, a movable piece 2 and a spring 3. The base 1 is provided with a first buckle part 11. The movable piece 2 is arranged on the base 1, and the movable piece 2 is provided with a second buckle part 21. The movable piece 2 can reciprocatingly slide relative to the base 1, so that the second buckle part 21 moves away from or approaches the first buckle part 11. The spring 3 is connected with the base 1 and the movable piece 2. When the second buckle part 21 moves away from the first buckle part 11, the spring 3 deforms to generate an elastic action against the second buckle part 21 moving away from the first buckle part 11.

[0034] In some embodiments, the base 1 is provided with a stop part 12, and the buckle device 1000 includes a locking piece 4. The locking piece 4 is arranged on the movable piece 2, and the locking piece 4 is configured to move at least partially relative to the movable piece 2. The locking piece 4 has a locking state in which the locking piece 4 abuts against the stop part 12, and an unlocking state in which the locking piece 4 is away from the stop part 12. When the second buckle part 21 moves away from the first buckle part 11 by a first distance, the locking piece 4 can move and switch to the locking state to keep the relative distance between the first buckle part 11 and the second buckle part 21. When the locking piece 4 switches to the unlocking state, the spring 3 drives the second buckle part 21 to approach the first buckle part 11. The first distance can be matched according to the to-be-buckled piece T to be buckled by the first buckle part 11 and the second buckle part 21, so as to satisfy that when the locking piece 4 is in the locking state, there is enough space between the first buckle part 11 and the second buckle part 21 for the to-be-buckled piece T to be disassembled.

[0035] The latching device 1000 provided in this embodiment of the application, by providing a locking member 4, switches to a locked state when the second latching part 21 moves away from the first latching part 11 by a first distance, so that the first latching part 11 and the second latching part 21 maintain a relative distance, thereby facilitating the removal of the latching device 1000 from the component T to be latched. When the latching device 1000 is used to latch the guide rail of electrical equipment, when removing the latching device 1000, the operator does not need to continuously pull the movable part 2 to overcome the elastic force of the elastic member 3 to move the second latching part 21 away from the first latching part 11, thereby improving the convenience of removing the latching device 1000.

[0036] In some embodiments, the sliding direction of the movable member 2 is parallel to the moving direction of the second latching part 11 relative to the first latching part 21.

[0037] Please see Figure 1 and Figure 2 In some embodiments, the locking member 4 includes an elastic portion 41 and a first abutting portion 42. The elastic portion 41 is connected to the first abutting portion 42. When the locking member 4 is in the locked state, the first abutting portion 42 abuts against the stop portion 12 along the direction X from the second latching portion 21 toward the first latching portion 11. When the locking member 4 switches to the unlocked state, the elastic portion 41 is subjected to force and undergoes elastic deformation, causing the first abutting portion 42 to move away from the stop portion 12.

[0038] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the locking member 4 includes a second abutment 43 disposed opposite to the first abutment 42, and an elastic portion 41 connected to the second abutment 43. When the locking member 4 is switched to the unlocked state, the first abutment 42 and the second abutment 43 move toward each other, and the elastic portion 41 is used for compression deformation. The stop portion 12 is provided with a clearance channel 12a extending along the sliding direction of the movable member 2, and the clearance channel 12a has an opening 12b formed at the end facing the locking member 4. The clearance channel 12a is used to accommodate the first abutment 42 and the second abutment 43 when the locking member 4 is in the unlocked state. When in the locked state (e.g. Figure 3 When (as shown), along the direction X of the second latching part 21 approaching the first latching part 11, the first abutting part 42 and the second abutting part 43 abut against the stop part 12. The elastic part 41, under pressure, undergoes elastic deformation, causing the first abutting part 42 and the second abutting part 43 to move towards each other until the first abutting part 42 and the second abutting part 43 enter the clearance channel 12a through the opening 12b, thereby allowing the locking member 4 to switch to the unlocked state (as shown). Figure 5 (As shown). The first abutting part 42 and the second abutting part 43, which are arranged opposite to each other, abut against the stop part 12 together. Compared with the first abutting part 42 being provided alone against the stop part 12, this is beneficial to improving the stability between the locking member 4 and the abutting part in the locked state.

[0039] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the elastic part 41 comprises a spiral part 411, a first connecting arm 412 and a second connecting arm 413, the spiral part 411 comprises a first end 4111 and a second end 4112, the first connecting arm 412 connects the first end 4111 and the first abutting part 42, the second connecting arm 413 connects the second end 4112 and the second abutting part 43, and the first connecting arm 412 and the second connecting arm 413 are arranged at an included angle. When the elastic part 41 is pressed, the spiral part 411 elastically deforms, and the included angle α between the first connecting arm 412 and the second connecting arm 413 decreases to drive the first abutting part 42 and the second abutting part 43 to move towards each other. When the locking piece 4 is in the locked state, by pressing the first connecting arm 412 and the second connecting arm 413, the spiral part 411 is forced to elastically twist, the included angle α between the first connecting arm 412 and the second connecting arm 413 continuously decreases, and the first abutting part 42 and the second abutting part 43 move close to each other until they enter the avoiding channel 12a through the opening 12b, at this time, the locking piece 4 is in the unlocked state, and under the action of the elastic piece 3, the second buckle part 21 moves towards the first buckle part 11 in the direction X.

[0040] In some embodiments, the movable piece 2 is provided with a mounting column 26, and the spiral part 4113 is arranged around the mounting column 26.

[0041] In some embodiments, the buckle device 1000 comprises a mounting bolt 27, the mounting bolt 27 is screwed and fixed to the mounting column 26, and the spiral part 4113 is limited between the screw cap 271 of the mounting bolt 27 and the movable piece 2.

[0042] In some embodiments, the locking piece 4 is integrally wound by a spring steel wire.

[0043] Please refer to Figure 3 , Figure 5 and Figure 6In some embodiments, the locking member 4 comprises a first supporting portion 44 and a second supporting portion 45, the first supporting portion 44 is connected with the first abutting portion 42, and the second supporting portion 45 is connected with the second abutting portion 43, and the first supporting portion 44 and the second supporting portion 45 at least partially overlap in the sliding direction of the movable member 2 when the locking member 4 is in the locked state. The portion of the first supporting portion 44 that overlaps with the second supporting portion 45 abuts against the second supporting portion 45, and the first supporting portion 44 and the second supporting portion 45 slide relative to each other when the included angle a between the first connecting arm 412 and the second connecting arm 413 changes. By arranging the first supporting portion 44 and the second supporting portion 45 to form a generally triangular ring structure together with the spiral portion 411, the first connecting arm 412, the second connecting arm 413, the first abutting portion 42, and the second abutting portion 43, the stability of the locking member 4 as a whole can be improved.

[0044] Referring to Figure 6 In some embodiments, the locking member 4 comprises a first bending portion 46 and a second bending portion 47, the first bending portion 46 is connected between the first abutting portion 42 and the first supporting portion 44, and the second bending portion 47 is connected between the second abutting portion 43 and the second supporting portion 45, and the first bending portion 46 and the second bending portion 47 are oppositely arranged in the direction from the first abutting portion 42 to the second abutting portion 43. The first supporting portion 44 comprises a third end portion 441 and a fourth end portion 442 that are oppositely arranged, and the second supporting portion 45 comprises a fifth end portion 451 and a sixth end portion 452 that are oppositely arranged, the third end portion 441 is connected with the first bending portion 46, the fourth end portion 442 is a free end extending towards the second bending portion 47, the fifth end portion 451 is connected with the second bending portion 47, and the sixth end portion 452 is a free end extending towards the first bending portion 46, and the first supporting portion 44 and the second supporting portion 45 are in contact.

[0045] In some embodiments, the second supporting portion 45 and the first supporting portion 44 are sequentially arranged in the direction X from the second clamping portion 21 towards the first clamping portion 11, and the first bending portion 46 is used to limit the sixth end portion 452 in the direction from the second abutting portion 43 towards the first abutting portion 42, and when the first connecting arm 412 and the second connecting arm 413 are compressed to change the included angle a, the sixth end portion 452 can move towards the first bending portion 46 until it abuts against the first bending portion 46. The limiting effect of the first bending portion 46 on the sixth end portion 452 can help to reduce the problem of excessive twisting of the spiral portion 4113 caused by excessive stress on the first connecting arm 412 and the second connecting arm 413, which can cause the spiral portion 4113 to fail.

[0046] In some embodiments, the first support portion 44 and the second support portion 45 are sequentially arranged in the direction of the first clamping portion 11 close to the second clamping portion 21, and the second bending portion 47 is configured to limit the fourth end portion 442 in the direction from the first abutting portion 42 to the second abutting portion 43. When the first connecting arm 412 and the second connecting arm 413 are pressed to change the included angle a, the fourth end portion 442 can move towards the second bending portion 47 until abutting against the second bending portion 47. The limiting effect of the second bending portion 47 on the fourth end portion 442 helps to reduce the problem that the excessive stress on the first connecting arm 412 and the second connecting arm 413 causes the spiral portion 4113 to be excessively twisted and thus fails.

[0047] In some embodiments, the axis of the first connecting arm 412 and the axis of the second connecting arm 413 are located in the same plane. Compared with the arrangement that the axis of the first connecting arm 412 and the axis of the second connecting arm 413 are located in different planes, the arrangement that the axis of the first connecting arm 412 and the axis of the second connecting arm 413 are located in the same plane helps to improve the stability of the first connecting arm 412 and the second connecting arm 413 when they are pressed, and reduce the additional stress or deformation of the elastic portion 411.

[0081] In order to facilitate the reader to understand the utility model, the disassembly process and working principle of the buckling device 1000 will be completely explained below by taking the guide rail strip as the to-be-fastened piece T as an example:

[0082] Please refer to Figures 1-5 and Figure 8 When the buckling device 1000 is in the initial state, the locking piece 4 is in the unlocked state, the first abutting part 42 and the second abutting part 43 are located in the avoiding passage 12a, the first abutting part 42 abuts against the surface of the first vertical plate 121 facing the second vertical plate 122, the second abutting part 43 abuts against the surface of the second vertical plate 122 facing the first vertical plate 121, along the direction X of the second buckling part 21 approaching the first buckling part 11, the third limiting part 25 abuts against the stop part 19, and the elastic piece 3 is in the compressed state.

[0083] The installation process of the buckling device 1000 is as follows:

[0084] First, the first recess part 111 is buckled into the seventeenth end part T1 of the guide rail strip, so that the first buckling part 11 buckles the seventeenth end part T1;

[0085] Then, the base 1 is pressed towards the guide rail strip, so that the eighteenth end part T2 abuts against the guide inclined surface 212 of the second buckling part 21 (as Figure 8As shown in the figure, the thrust of the eighteenth end T2 acts on the second buckle part 21, overcoming the sliding friction between the first abutting part 42 and the surface of the first vertical plate 121 towards the second vertical plate 122, the sliding friction between the second abutting part 43 and the surface of the second vertical plate 122 towards the first vertical plate 121, and the elastic force generated by the compression of the elastic member 3, so that the plate body 24 slides in the sliding groove 1a, thereby driving the second buckle part 21 to move in the direction Y away from the first buckle part 11, and in the process of moving the second buckle part 21, the eighteenth end T2 continuously abuts and slides along the guide inclined surface 212 until it finally slides into the second recessed groove part 212, at this time, under the action of the elastic force of the elastic member 3, the second buckle part 21 and the first buckle part 11 jointly clamp and fix the guide rail strip, thus completing the installation process of the buckle device 1000.

[0086] The disassembly process of the buckle device 1000:

[0087] Pulling the part of the plate body 24 protruding from the base 1 in the direction Y drives the movable member 2 as a whole to move in the direction Y away from the first buckle part 11 along the second buckle part 21, when the moving distance reaches the first distance, the first abutting part 42 and the second abutting part 43 automatically exit the avoidance channel 12a at the opening 12b, losing the limiting effect of the first vertical plate 121 and the second vertical plate 122, under the action of the spiral part 4113, the angle α between the first connecting arm 412 and the second connecting arm 413 becomes larger, thereby driving the first abutting part 42 and the second abutting part 43 to pop out and abut on the first flat part 1211 and the second flat part 1221 respectively, and the locking member 4 switches to the locked state, at this time the buckle device 1000 can be removed from the guide rail strip.

[0088] Restoring the buckle member to the initial state:

[0089] Pressing the first connecting arm 412 and the second connecting arm 413 until the locking member 4 switches to the unlocked state, the elastic force of the elastic member 3 automatically drives the movable member 2 to move in the direction X of the second buckle part 21 towards the first buckle part 11, until the third limiting part 25 abuts on the stop part 19.
