[0006] Furthermore, the movable hinge is provided with a first clearance groove and a receiving groove. The limiting member passes through the first clearance groove and abuts against the first hinge part. The elastic member is disposed in the receiving groove, and the two ends of the elastic member abut against the groove wall of the receiving groove and the limiting member, respectively.

[0007] Furthermore, the limiting member is provided with a second clearance groove, which is provided correspondingly to the receiving groove. The two ends of the elastic member abut against the groove wall of the receiving groove and the groove wall of the second clearance groove, respectively.

[0008] Furthermore, a top shaft is inserted into the receiving groove, and there is an angle between the moving direction of the top shaft and the limiting member, and one end of the elastic member abuts against the top shaft.

[0009] Furthermore, a guide protrusion is provided on the groove wall of the second clearance groove, and the other end of the elastic element is sleeved on the guide protrusion.

[0010] Furthermore, a spring pin is provided on the side of the movable hinge facing the fixed hinge. The spring pin protrudes from the outer wall of the movable hinge, and when the movable hinge rotates, the spring pin can abut against the outer wall of the fixed hinge.

[0011] Furthermore, the hinge mechanism also includes a torsion spring, which is disposed between the first hinge portion and the second hinge portion, with the two torsion arms of the torsion spring abutting against the first hinge portion and the second hinge portion respectively.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 6As shown, this utility model embodiment provides a hinge mechanism, which includes a fixed hinge 10, a movable hinge 20, and a limiting component 30. The fixed hinge 10 has a first hinge portion 11 and a first connecting portion; the movable hinge 20 has a second hinge portion 21 and a second connecting portion, and the first hinge portion 11 and the second hinge portion 21 are hinged together; the limiting component 30 includes a limiting member 31 and an elastic member. A limiting step 111 is provided on the outer periphery of the first hinge portion 11, and the limiting member 31 is movably disposed on the movable hinge 20. The hinge axis of the first hinge portion 11 and the second hinge portion 21 forms an angle with the moving direction of the limiting member 31. The elastic member can provide elastic force to the limiting member 31 so that the limiting member 31 abuts against the outer periphery of the first hinge portion 11; wherein, when the movable hinge 20 rotates, the limiting member 31 can pass over the limiting step 111 and be limited and engaged with the limiting step 111.

[0033] The hinge mechanism of this utility model includes a fixed hinge 10, a movable hinge 20, and a limiting component 30. The fixed hinge 10 is connected to the housing via a first connecting part, and the movable hinge 20 is connected to the housing door via a second connecting part. When the housing door is opened, the movable hinge 20 rotates relative to the fixed hinge 10. Since the limiting component 31 is movably mounted on the movable hinge 20, it can rotate with the movable hinge 20. Under the action of the elastic force of the elastic element, the limiting component 31 can always abut against the outer periphery of the first hinge part 11. After the movable hinge 20 drives the limiting component 31 to rotate and pass the limiting step 111 of the first hinge part 11, the limiting component 31 extends under the action of the elastic force of the elastic element and engages with the limiting step 111, thereby forming a blocking effect to prevent the movable hinge 20 from rotating in the opposite direction relative to the fixed hinge 10, thus facilitating operation by the operator.

[0034] The limiting step 111 can be set as a limiting groove or other limiting structure to prevent the movable hinge 20 from rotating in any direction, thus improving the limiting effect of the movable hinge 20.

[0035] In other embodiments, the limiting member 31 can be movably disposed on the fixed hinge 10, and the limiting member 31 can always abut against the second hinge portion 21. Correspondingly, the limiting step 111 is disposed on the second hinge portion 21.

[0036] like Figure 1 and Figure 4As shown, the movable hinge 20 is provided with a first clearance groove 22 and a receiving groove 23. The limiting member 31 passes through the first clearance groove 22 and abuts against the first hinge portion 11. The elastic member is disposed in the receiving groove 23, with its two ends abutting against the groove wall of the receiving groove 23 and the limiting member 31, respectively. With the above structure, the first clearance groove 22 can avoid the limiting member 31, and the receiving groove 23 can accommodate the elastic member, which has the advantages of simple structure and easy installation.

[0037] The first clearance groove 22 and the receiving groove 23 can be set separately or connected together.

[0038] like Figure 5 As shown, the limiting member 31 is provided with a second clearance groove 311, which is correspondingly provided with the receiving groove 23. The two ends of the elastic member abut against the groove wall of the receiving groove 23 and the groove wall of the second clearance groove 311, respectively. The second clearance groove 311 can be used to avoid the elastic member.

[0039] The fact that the second clearance groove 311 and the receiving groove 23 are respectively set means that the second clearance groove 311 and the receiving groove 23 partially overlap.

[0040] like Figure 3 As shown, a support shaft 231 is inserted into the receiving groove 23. The support shaft 231 and the moving direction of the limiting member 31 form an angle, and one end of the elastic member abuts against the support shaft 231. Using the support shaft 231 to abut against the elastic member has the advantages of simple structure and easy installation.

[0041] In other embodiments, the length of the second clearance groove 311 may be greater than its moving distance, thereby eliminating the need for the abutment shaft 231, as long as the limiting member 31 does not interfere with the movable hinge 20 when it moves.

[0042] In this embodiment, the extending direction of the abutment shaft 231 is perpendicular to the moving direction of the limiting member 31.

[0043] The elastic element is a spring, and the extension direction of the spring is the same as the movement direction of the limiting element 31.

[0044] like Figure 5 As shown, a guide protrusion 312 is provided on the groove wall of the second clearance groove 311, and the other end of the elastic element is sleeved on the guide protrusion 312. The guide protrusion 312 guides the spring and prevents the spring from deflecting during compression and extension.

[0045] In this embodiment, a receiving sleeve is also provided in the receiving groove 23, the spring is placed in the receiving sleeve, the guide protrusion 312 extends into the receiving sleeve, and the abutment shaft 231 passes through the receiving sleeve.

[0046] like Figure 3 As shown, a spring pin 24 is provided on the side of the movable hinge 20 facing the fixed hinge 10. The spring pin 24 protrudes from the outer wall of the movable hinge 20. When the movable hinge 20 rotates, the spring pin 24 can abut against the outer wall of the fixed hinge 10. During the closing process of the door, the contact between the spring pin 24 and the fixed hinge 10 is earlier than the contact between the movable hinge 20 and the fixed hinge 10. Thus, the spring pin 24 can be used to form a buffer, avoiding hard contact between the movable hinge 20 and the fixed hinge 10, and extending the service life.

[0047] The spring pin 24 includes a spring and a pin disposed at the front end of the spring. The pin is limited on the movable hinge 20, and the spring provides elastic force to push the pin to move and provide cushioning.

[0048] like Figure 1 As shown, the hinge mechanism also includes a torsion spring 40, which is disposed between the first hinge portion 11 and the second hinge portion 21. The two torsion arms of the torsion spring 40 abut against the first hinge portion 11 and the second hinge portion 21, respectively. The torsion spring 40 provides torsional restoring force, causing the movable hinge 20 to rotate automatically after the contact limiting member 31 and the limiting step 111 are engaged, thereby closing the door 60.

[0049] like Figure 3 and Figure 6 As shown, the first hinge portion 11 includes a hinge shaft, and the second hinge portion 21 includes a hinge hole. The hinge shaft passes through the hinge hole, and an annular protrusion is provided on the hinge shaft. A limiting step 111 is provided on the annular protrusion. By adopting the above structure and setting the limiting step 111 on the annular protrusion of the hinge shaft, it has the advantages of simple structure and easy processing.

[0050] Both the first connecting part and the second connecting part are clearance holes for the connecting member. With the above structure, the connecting member can pass through the clearance hole to connect the movable hinge 20 to the door 60 and the fixed hinge 10 to the housing 50.

[0051] In this embodiment, the connector is a screw.

[0052] like Figure 7As shown, another embodiment of this application provides an electric meter box, which includes a box body 50, a box door 60, and a hinge mechanism. The box door 60 is closable on the box body 50. The movable hinge 20 of the hinge mechanism is connected to the box door 60, and the fixed hinge 10 of the hinge mechanism is connected to the box body 50. The hinge mechanism is the hinge mechanism provided above. Using the above-mentioned meter box, the fixed hinge 10 is connected to the box body through the first connecting part, and the movable hinge 20 is connected to the box door through the second connecting part. When the box door is opened, the movable hinge 20 rotates relative to the fixed hinge 10. Since the limiting member 31 is movably set on the movable hinge 20, the limiting member 31 can rotate with the movable hinge 20. Under the action of the elastic force of the elastic member, the limiting member 31 can always abut against the outer periphery of the first hinge part 11. After the movable hinge 20 drives the limiting member 31 to rotate and pass the limiting step 111 of the first hinge part 11, the limiting member 31 extends under the action of the elastic force of the elastic member and cooperates with the limiting step 111 to limit and thus form a blocking effect, preventing the movable hinge 20 from rotating in the opposite direction relative to the fixed hinge 10, thereby facilitating the operation of the operator.

[0053] The hinge mechanism provided in this embodiment has the following advantages:

[0054] (1) The door has a closing reset function: Without changing the original door structure, the door hinge is improved into a reset hinge that can automatically rotate and has a certain torque. Its opening force is moderate, ensuring that the door is not easily opened by external force.

[0055] (2) The door has a closing buffer function: a closing buffer structure is added at the closing point of the door to solve the problem that the door is easily damaged by instantaneous collision when closing and the door is not closed tightly due to repeated collisions when closing, thereby enhancing the service life and closing stability of the door;

[0056] (3) The cabinet door has an opening angle positioning function: Without changing the original cabinet door structure, an opening angle positioning device is added to the cabinet door hinge. This ensures that the cabinet door is always kept in a 90° open position when the cabinet door is opened, providing convenience for operators to work inside the cabinet.
