Description

A tension latch for the door of an energy storage box Technical Field

[0001] This utility model relates to the field of lock technology, specifically a tensioning latch for the door of an energy storage box. Background Technology

[0002] Against the backdrop of "dual carbon" (carbon and energy conservation), the energy storage industry has developed rapidly. In recent years, energy storage boxes, as an innovative energy storage solution, have many advantages, including high energy density, long service life, high integration, easy installation and hoisting, and being environmentally friendly and easy to maintain. They have broad application prospects and market potential in many fields such as energy supply, grid stability, microgrids, and emergency backup power. Consequently, safety has become increasingly important. To meet safety requirements, many projects have installed passive explosion relief panels. When the internal pressure reaches a certain level, these panels automatically release pressure to prevent large-scale explosions and greater safety hazards. Corresponding to the pressure, the internal door locks must have sufficient pressure resistance to ensure they remain closed until the explosion relief panels open.

[0003] Currently, the strength of commonly used linkage lock latches does not meet the corresponding strength requirements, which poses a risk of loss of control. To address this, we provide a tensioning latch for energy storage box doors. Summary of the Invention

[0004] The purpose of this utility model is to provide a tension latch for the door of an energy storage box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A latch for a door of an energy storage box includes a lock body, a rotating column passing through the inside of the lock body, a locking plate being provided at the top of the lock body, a retaining spring being sleeved between the lock body and the locking plate, and an anti-loosening nut being threadedly connected to one end of the rotating column passing through the locking plate.

[0007] A connecting rod is inserted inside the bottom of the lock body. An M5 flat washer is provided at the bottom of one end of the connecting rod, and an M5 cross flat head bolt is inserted inside the M5 flat washer.

[0008] Preferably, the lock body and the rotating column are elastically connected by a snap ring.

[0009] Preferably, one end of the rotating column is connected to the locking plate via a lock nut, and one end of the rotating column is adapted to the square hole of the locking plate.

[0010] Preferably, the other end of the rotating column is connected to one end of the connecting rod (4) by an M5 crosshead bolt.

[0011] Preferably, the other end of the rotating column is shaped like a plum blossom and is adapted to the plum blossom hole at one end of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The lock body is designed with an irregularly shaped base, which increases the contact area and reduces deformation caused by local stress concentration. Four bolt fixing points are added to the lock body, and the lock body is fixed to the energy storage box door by the corresponding four bolts, ensuring that the lock body can still be firmly fixed to the energy storage box door under the action of force.

[0014] The rotating column is machined from a 14mm diameter column, which ensures that the stud will not be damaged under stress, the deformation will not exceed the requirements, and it can still be opened normally after deformation.

[0015] Reinforcing ribs are added to the locking plate to ensure that the locking plate does not fail under a thrust of 6500N.

[0016] The rotating column and connecting rod are fitted with plum blossom-shaped ends and plum blossom holes, and are fixed with M5 cross-head bolts and M5 flat washers, ensuring a firm and stable connection that can effectively transmit power.

[0017] The overall structure is reasonably designed, and all components work together to meet the pressure requirements of the energy storage box before the explosion, ensuring that the box door remains closed and improving the safety of the energy storage box. Attached Figure Description

[0024] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4. This utility model provides a technical solution: a tensioning latch for an energy storage box door, including a lock body 1. The lock body 1 is set as an irregularly shaped base, which increases the contact area and reduces deformation caused by local stress. Four bolt fixing points are added to the lock body 1. The lock body 1 is fixed to the energy storage box door by the corresponding four bolts, ensuring that the lock body 1 can still be fastened to the energy storage box door under the action of force.

[0026] A rotating pin 2 is inserted inside the lock body 1, and a locking plate 3 is provided on the top of the lock body 1. A retaining spring 8 is sleeved between the lock body 1 and the locking plate 3. A locking nut 5 is threaded to one end of the rotating pin 2 through the locking plate 3. The lock body 1 and the rotating pin 2 are elastically connected by the retaining spring 8. One end of the rotating pin 2 is connected to the locking plate 3 by the locking nut 5, and one end of the rotating pin 2 is adapted to the square hole of the locking plate 3.

[0027] The rotating column 2 is made of a column with a diameter of 14mm, which ensures that the stud will not be damaged under the force of the locking plate 3, the deformation will not exceed the requirements, and it can still be opened normally after deformation.

[0028] Reinforcing ribs are added to the locking plate 3 locally to ensure that the strength of the locking plate 3 meets the requirements of not failing under a thrust of 6500N.

[0029] A connecting rod 4 is inserted through the bottom of the lock body 1. An M5 flat washer 6 is provided at the bottom of one end of the connecting rod 4. An M5 cross flat head bolt 7 is inserted through the inside of the M5 flat washer 6. The other end of the rotating column 2 is connected to one end of the connecting rod 4 through the M5 cross flat head bolt 7. The other end of the rotating column 2 is shaped like a plum blossom and is adapted to the plum blossom hole at one end of the connecting rod 4.

[0030] Pass the spline end of the rotating column 2 through the spline hole at one end of the connecting rod 4 and thread it with the M5 cross flat head bolt 7. Also, press the M5 flat washer 6 against the locking plate 3 to securely connect the locking plate 3 to the rotating column 2.

[0031] Working principle:

[0032] Several lock bodies 1 are sequentially installed on the energy storage box door using bolts, and several connecting rods 4 are movably connected to the connecting rod in Figure 4 using pins.

[0033] When the connecting rod moves, the connecting rod pushes the connecting rod 4 to rotate, which in turn drives the rotating column 2 to rotate. Since the rotating column 2 is connected to the locking plate 3 through the anti-loosening nut 5, it can drive the locking plate 3 to rotate. When the locking plate 3 is in a vertical state, the locking plate 3 is disengaged from the lock hole of the energy storage box door frame, and the energy storage box door can be opened. When the locking plate 3 is in a horizontal state, the locking plate 3 is inserted into the lock hole of the energy storage box door frame, which can lock the energy storage box door.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
