Description

Technical Field

[0001] This utility model relates to the field of telescopic lock technology, specifically an explosion-proof telescopic lock. Background Technology

[0002] In battery storage compartments, due to the risks of thermal runaway, electrolyte leakage, short circuit and explosion caused by a large number of lithium batteries, explosion-proof telescopic locks are key protective components to ensure the safety of the compartment. An explosion-proof telescopic lock is a special lock with explosion-proof function and telescopic lock body structure. It is usually composed of lock body, telescopic lock head, drive device and other parts, and is mainly used in places and equipment that require explosion-proof safety protection.

[0003] When existing telescopic door locks are installed on battery storage compartments, the impact force of a battery explosion is relatively large. The bolt of a single-point locking door lock cannot withstand the impact pressure of the explosion. Furthermore, the cooperation between the moving and fixed parts of the bolt opening and closing is difficult to control precisely. Excessive gaps may lead to loosening of the lock and affect the fixing effect of the lock body structure. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof telescopic lock to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof telescopic lock, comprising a bolt and a lock body, wherein the lock body is provided with a limiting block and a steering handle respectively, the steering handle rotates inside the limiting block, the bolt is provided with a screw, the screw is provided with a retaining ring and a first washer respectively, the screw is provided with a pin, and the bottom end of the screw is connected to a nut;

[0006] The lock body is equipped with a lock cylinder shell and a spring. The lock cylinder is located inside the lock cylinder shell and is connected to a screw. The steering handle is equipped with a matching second washer and a screw. The bottom of the steering handle is equipped with a cotter pin and a third washer.

[0007] Preferably, the latch and lock body are made of stainless steel, and the extension stroke of the latch is 7mm, which facilitates the control of the extension stroke of the latch to open and close the telescopic lock structure respectively.

[0008] Preferably, the inner side of the limiting block has a notch with an angle of 135°, and the steering handle is set in the notch. The angle of the notch facilitates precise control of the steering angle of the steering handle, thereby enabling precise control of the travel of the locking tongue.

[0009] Preferably, the lock cylinder housing and the lock cylinder are disposed on the outside of the screw, and the screw has a shaft hole. The pin is matched with the shaft hole, which facilitates the connection between the pin and the shaft hole and makes it convenient for the components to move together.

[0010] Preferably, the nut is an M14 lock nut, and the M14 lock nut is located at the bottom of the outer side of the screw rod, which facilitates fixing the bottom of the screw rod and prevents the locking tongue from disengaging from the screw rod during its travel.

[0011] Preferably, the bottom end of the steering handle is provided with a positioning post, and a third washer is provided on the outside of the positioning post, while a cotter pin is inserted inside the positioning post, which facilitates the setting of a positioning structure below the handle to prevent the handle from rotating on its own.

[0012] The explosion-proof telescopic lock proposed in this utility model has at least the following beneficial effects:

[0013] This explosion-proof telescopic lock is constructed entirely of stainless steel for the bolt and lock body, enabling the bolt to withstand loads exceeding 10,000N. Multiple locking points are distributed throughout the door, and the synchronous action of these multiple locking points evenly distributes the locking force, enhancing overall resistance to deformation and sealing performance. Furthermore, the combination of the steering handle and the limit block allows for precise control of the rotation range of the steering handle, ensuring accurate coordination between the moving and fixed parts during the opening, closing, and telescopic movement of the bolt. This prevents excessively large or small gaps in the lock body structure that could lead to loosening, friction, or deformation causing jamming and affecting operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Please see Figure 1-4 The present invention provides an embodiment of an explosion-proof telescopic lock, comprising a bolt 1 and a lock body 2, wherein the bolt 1 and the lock body 2 are made of stainless steel, and the telescopic stroke of the bolt 1 is 7mm, which facilitates the control of the stroke of the bolt 1 to open and close the telescopic lock structure respectively.

[0021] The lock body 2 is provided with a limiting block 3 and a turning handle 4 respectively. The turning handle 4 rotates inside the limiting block 3. The limiting block 3 has a notch on its inner side with an angle of 135°. The turning handle 4 is set in the notch. By setting the angle of the notch, it is easy to accurately control the turning angle of the turning handle 4, thereby accurately controlling the stroke of the lock tongue 1.

[0022] The locking tongue 1 has a screw 5 inside, and a retaining ring 6 and a first washer 7 are respectively provided on the screw 5. A pin 8 is sleeved inside the screw 5. A nut 9 is connected to the bottom end of the screw 5. The nut 9 is an M14 anti-loosening nut, and the M14 anti-loosening nut is located at the bottom end of the outside of the screw 5, which facilitates fixing the bottom end of the screw 5 and prevents the locking tongue 1 from going out of the screw during its stroke.

[0023] The lock body 2 has a lock cylinder shell 10 and a spring 12 inside. The lock cylinder shell 10 contains a lock cylinder 11, which is connected to the screw 5. The lock cylinder shell 10 and the lock cylinder 11 are located on the outside of the screw 5. The screw 5 has a shaft hole, and the pin 8 matches the shaft hole to facilitate the connection between the pin 8 and the shaft hole, which facilitates the linkage of the component structure. The steering handle 4 is provided with a matching second washer 13 and screw 14. The bottom of the steering handle 4 is provided with a positioning post, and the outside of the positioning post is provided with a third washer 16. The inside of the positioning post is provided with a cotter pin 15, which facilitates the setting of a positioning structure below the handle to prevent the handle from rotating. The bottom of the steering handle 4 is provided with a cotter pin 15 and a third washer 16.

[0024] Example 1, as Figure 1-4 As shown, when the door lock structure is applied to the battery energy storage compartment, in order to withstand the impact force generated by the battery explosion, the door lock structure is distributed on the top, bottom and sides of the edge of the locked object, so as to evenly distribute the locking force. According to the application case with 7 locking points, the pressure that the entire door can withstand can reach more than 0.2 bar.

[0025] Working principle: This explosion-proof telescopic lock;

[0026] When using this telescopic lock structure, the lock body structure is set on the edge of the locked object and multiple sets are distributed in a multi-point locking manner to seal the battery storage compartment door for explosion protection. The limit block 3 limits the steering handle 4, so that the maximum rotation angle of the steering handle 4 within the limit block 3 is 135°. This causes the steering handle 4 to drive the lock cylinder 11, lock cylinder shell 10 and screw 5 to adjust their movement. Under the extension and retraction of the spring 12, the extension and retraction stroke of the lock tongue 1 is 7mm, realizing precise control of the locking stroke of the lock tongue 1, increasing the matching accuracy between the moving parts and the fixed parts of the lock body structure, and further enhancing the locking and fixing effect.
