[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0022] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.
[0023] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.
[0024] This embodiment provides a novel locking rod snap-fit connection structure, which is installed on the single or double doors of a switch cabinet, providing convenient pre-installation when installing the switch cabinet door panel.
[0025] Specifically, the snap-fit connection structure includes a door lock and a lock rod 2. The door lock includes a lock body 11 and a rack 12. The rack 12 is movably mounted on the lock body 11, and one end of the rack 12 is exposed on one side of the lock body 11. The lock body 11 is provided with a keyhole, and the lock body 11 is provided with an action structure that is linked to the keyhole. When a key is inserted into the keyhole of the lock body 11 and rotated, the rack 12 can be driven to move relative to the lock body 11. In this embodiment, the rack 12 preferably performs a telescopic movement relative to the lock body 11.
[0026] Both the door lock and the locking rod 2 are installed on the cabinet body. The locking rod 2 is movably installed on the side of the cabinet door. One end of the locking rod 2 is connected to the rack 12, and the other end is used to lock and unlock the cabinet door. Preferably, the cabinet door and the cabinet body are provided with locking grooves. When the cabinet door is closed, the action of the rack 12 can drive the locking rod 2 to move, so that the other end of the locking rod 2 can be inserted into or disengaged from the locking groove. When inserted, it blocks the cabinet door to lock it, and when disengaged, it unlocks it.
[0027] The rack 12 and the locking rod 2 are connected by a snap-lock structure to form a detachable connection, enabling the pre-installation of the door lock and the locking rod 2 before installation into the cabinet. The snap-lock structure includes a through hole 21 at the end of the locking rod 2 and a locking hook 13 at the end of the rack 12. The through hole 21 is a straight through hole structure with a first set thickness and a first set width. The locking hook 13 is bent at the end of the rack 12, preferably at a right angle, so that the locking hook 13 is perpendicular to the locking rod 2 when the rack 12 is connected to the locking rod 2, which facilitates the pulling action of the rack 12 on the locking rod 2. The locking hook 13 has a second set thickness and a second set width. The second set thickness of the locking hook 13 is slightly smaller than the first set thickness of the through hole 21, and the second set width of the locking hook 13 is slightly smaller than the first set width of the through hole 21. Therefore, when the width direction of the locking hook 13 is parallel to the width direction of the through hole 21, the locking hook 13 can be inserted into the through hole 21.
[0028] Furthermore, the locking hook 13 is provided with inwardly recessed locking grooves 131 on both sides along the second set width direction. The locking grooves 131 on both sides form a waist-tight structure in the middle of the locking hook 13, so that the width of the locking hook 13 portion between the two locking grooves 131 is less than the second set width of the locking hook 13, and also less than the first set thickness of the through hole 21. Moreover, the width of the locking groove 131 is greater than the thickness of the locking rod 2. Therefore, when the locking hook 13 is inserted into the through hole 21 until the locking groove 131 is aligned with the through hole 21, the locking rod 2 and the locking hook 13 can rotate relative to each other, so that the width direction of the locking hook 13 is no longer parallel to the width direction of the through hole 21. Then, the locking rod 2 is restricted in the locking groove 131, so that the locking groove 131 and the through hole 21 are engaged, and the locking rod 2 and the locking hook 13 cannot be disengaged, thus forming a connection relationship.
[0029] Preferably, when the locking rod 2 and the locking hook 13 are connected, the length direction of the locking rod 2 is in the same direction as the extension and retraction direction of the rack 12. Thus, the extension and retraction of the rack 12 can drive the translational movement of the locking rod 2, thereby enabling the locking rod 2 to lock and unlock the cabinet door.
[0030] The locking rod 2 has mounting holes for bolts to pass through, so that the locking rod 2 can be installed on the cabinet with bolts. The mounting holes have a set length to allow the bolts to move to a position, and the length direction of the mounting holes is opened along the direction of the translation movement of the locking rod 2 to support the movement of the locking rod 2.
[0031] The ends of the locking hook 13 are also provided with guide chamfers on both sides along the second width direction to facilitate the alignment and insertion of the locking hook 13 into the through hole 21.
[0032] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
