DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Embodiment 1

[0029] Reference Figure 1-Figure 5 As shown, a door lock structure of the utility model comprises:

[0030] The support frame 1 comprises a base 11, on which a first boss 12, a second boss 13 and a third boss 14 are arranged at intervals along the length direction thereof, and the first boss 12, the second boss 13 and the third boss 14 are all provided with mutually coaxial through holes 15, and the inner walls of the through holes 15 of the second boss 13 and the third boss 14 are respectively provided with first protrusions 16 and second protrusions 17 at positions corresponding to each other;

[0031] The plug rod 2 is a round rod matching the diameter of the through hole 15. The plug rod 2 is provided with a plurality of annular grooves 21 arranged at intervals in the length direction thereof, and a groove 22 extending in the length direction thereof is provided on the side surface of the plug rod 2. The groove 22 extends from one end of the plug rod 2 to the other end and passes through the annular groove 21;

[0032] The password ring 3 is provided with multiple annular grooves 21 respectively corresponding to each other. The password ring 3 is an annular structure whose inner diameter matches the outer diameter of the insertion rod 2. A third protrusion 31 is provided on the inner wall of the password ring 3, and a plurality of password numbers 32 arranged at intervals around the circumference are provided on the circumferential surface of the password ring 3.

[0033] Principle of use: first install the support frame 1 horizontally on the cabinet door of the cabinet body, and then pass the insertion rod 2 through the through holes 15 of the first boss 12, the second boss 13 and the third boss 14 in sequence, and ensure that the groove 22 corresponds to the position of the first protrusion 16 and the second protrusion 17 during the insertion process. When the insertion end of the insertion rod 2 has just passed through the through hole 15 of the second boss 13, first sleeve a fixing ring 4 on the insertion end of the insertion rod 2, and then sleeve multiple password rings 3 in sequence (the third protrusions 31 on the multiple password rings 3 correspond to the position of the groove 22, so that they can be sleeved on the insertion rod 2), and finally sleeve another fixing ring 4, and then the insertion rod 2 passes through the through hole 15 of the third boss 14. At this time, the fixing ring 4 and the password ring 3 arranged in sequence between the second boss 13 and the third boss 14 are restricted between the second boss 13 and the third boss 14, and when the insertion rod 2 is inserted into place, the multiple password rings 3 respectively corresponds to the position of an annular groove 21, and each password ring 3 can be rotated along its corresponding annular groove 21 through the third protrusion 31 thereon, and finally the lever 5 is screwed on the threaded hole 23 on the section of the plug rod 2 located between the first protrusion 12 and the second protrusion 13 to complete the installation of the door lock; the section of the plug rod 2 passing through the through hole 15 of the third protrusion 14 can be inserted into the corresponding jack on the cabinet body so that the cabinet door cannot be opened, and then the password of the password ring 3 is scrambled (rotating the password ring), that is, at least one of the third protrusions 31 of the password ring 3 is not in the position corresponding to the groove 22, at this time the plug rod 2 cannot move, and the cabinet door is locked; when the cabinet door needs to be opened, each password ring 3 is rotated to a predetermined number (corresponding to a series of predetermined passwords), that is, the third protrusions 31 of each password ring 3 are all located in the groove 22, at this time the plug rod 2 can be pulled out of the jack, and the cabinet door can be opened.

[0034] The door lock structure of the utility model adopts the form of a password lock, and the energy storage cabinet door can be locked or unlocked without using a key. It is easy to operate and can avoid the risk and trouble caused by key loss. In addition, the various components of the door lock structure are mechanically connected, and each component can be disassembled, which is simpler and more convenient for manufacturing and later replacement. At the same time, when one of the components is damaged, only the corresponding component needs to be replaced, which can reduce the cost of use. The entire door lock structure has a simple structure, is easy to install and maintain, and is suitable for practical use.

[0035] Reference Figure 4 As shown, further, a fixing ring 4 is included, and the fixing ring 4 is a ring-shaped structure whose inner diameter matches the outer diameter of the insertion rod 2. Specifically, the fixing ring 4 and the password ring 3 which are sequentially sleeved on the insertion rod 2 fit together to form a cylinder that matches the spacing between the second boss 13 and the third boss 14, so that the password ring 3 is restricted to a predetermined position, and the password ring 3 can only rotate at its position and will not move laterally, thereby ensuring that the password ring 3 corresponds to a position of an annular groove 21.

[0036] Furthermore, one end of the groove 22 extends to the outside of an end surface of the insertion rod 2 , and the other end of the groove 22 extends to a position of two-thirds of the length of the insertion rod 2 .

[0037] Furthermore, a lever 5 is vertically connected to the side surface of the insertion rod 2, and the lever 5 and the groove 22 are located on the same straight line.

[0038] Reference Figure 5 As shown, further, the lever 5 is a round rod, one end of the lever 5 is coaxially provided with a stud 51, a threaded hole 23 located in the same straight line as the groove 22 is vertically opened on the side of the plug rod 2, and the plug rod 2 is screwed into the threaded hole 23 through the stud 51. Specifically, the lever 5 is limited between the first boss 12 and the second boss 13, so that the range of movement of the plug rod 2 can be limited, so that the plug rod 2 will not be separated from the support frame 1, and the lever 5 is also convenient for the operator to insert and remove the plug rod 2.

[0039] Furthermore, the first protrusion 16 , the second protrusion 17 and the third protrusion 31 are all rectangular parallelepiped structures.

[0040] Furthermore, the groove 22 is a straight groove that matches the shape and size of the first protrusion 16, the second protrusion 17 and the third protrusion 31. Specifically, the first protrusion 16, the second protrusion 17 and the third protrusion 31 serve as stoppers for the insertion rod 2, so that the insertion rod 2 cannot rotate and can only move along a straight line. There is a certain range of motion between the first protrusion 16, the second protrusion 17 and the third protrusion 31 to ensure that the insertion rod 2 can slide.

[0041] Reference Figure 3 As shown, further, the password ring 3 includes a main body in the shape of a decagonal prism, and a central hole matching the outer diameter of the plug rod 2 is coaxially opened on the main body to form a ring-shaped password ring 3, and the ten edges of the password ring 3 are sequentially arranged with password numbers 32 of 0-9, and a third protrusion 31 is arranged on the inner wall of the central hole, and the third protrusion 31 corresponds to the position of any password number 32. Specifically, the diameter of the central hole of the password ring 3 is slightly larger than the diameter of the plug rod 2, that is, the password ring 3 has a certain activity space in the diameter direction of the plug rod 2, but it is necessary to ensure that the height of the free end of the third protrusion 31 is always lower than the circumferential surface of the plug rod 2. It can be imagined that the password ring 3 is set to be in the shape of a decagonal prism. When the password ring 3 is rotated, the edge surface of the password ring 3 facing the base 11 can be used as the support surface of the password ring 3, so that the password ring 3 can be kept in one state, which is convenient for the operator to identify and adjust the password.

[0042] Furthermore, the lengths of the first protrusion 16 , the second protrusion 17 and the third protrusion 31 are not greater than the lengths of the holes in which they are located.

[0044] The utility model also discloses an energy storage cabinet, comprising the door lock structure of embodiment 1. The door lock mechanism of the utility model can be used as a door lock for a variety of cabinets, is easy to use, and has high versatility.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
