Embodiment Construction

[0022] refer to Figure 1-Figure 2 . In the following description of the embodiment, a multi-point mechanical lock for anti-loosening reinforced cabinets includes: a lock cylinder mechanism composed of a lock cylinder 6 connected to a gear 5, and the lock cylinder 6 with a rotating square shaft drives the gear 5 along both sides of the lock box 13 Push the connecting rod up and down, push it into the chute 2 at both ends and enter the limit mechanism of the lock buckle 1 at both ends, wherein the lock tongue 10 is connected to the gear 5 through the lock hole of the lock box cover 12, and the key pushes the stop pin 8 to compress the spring 7 to connect The square shaft lock cylinder 6, after the stop pin 8 disengages from the lock cover 9, rotate the square shaft lock cylinder 6 to drive the lock tongue 10 to rotate, and at the same time drive the end gear 5 to rotate, and the gear 5 is linked with the racks 4 on both sides to push the connecting rod 3, Sliding under the lim...

Abstract

The invention discloses a multi-point mechanical lock for an anti-dropping reinforced cabinet, and aims to provide a mechanical door lock which is resistant to strong vibration and strong impact mechanical environment. According to the technical scheme, a lock tongue (10) is connected with a gear through a lock hole of a lock box cover (12), a key push a stop pin (8) to compress a spring (7) to connect with a square shaft lock core (6), after the stop pin is separated from a lock cover (9), the square shaft lock core is rotate to drive the lock tongue to rotate, the end gear is driven to rotate at the same time, the gear is linked with racks (4) at two sides, connecting rods (3) are pushed to slide under the limiting and guiding action of sliding chutes (2) at two ends, the connecting rodsare clamped and locked in end locking catches (1), and the lock tongue (10) is rotationally clamped into a middle locking catch (11), so that the two end locking catches (1) and the middle locking catch clamped into the middle generate larger compression pre-tightening force; after the lock tongue is locked in place, the key is withdrawn; and the spring (7) pushes the stop pin to be clamped intothe lock cover (9), so that the anti-dropping function of resisting the strong vibration and the strong impact mechanical environment is realized.

Description

technical field [0001] The invention relates to an anti-detachment reinforced multi-point mechanical lock for cabinets used in electromagnetic compatibility requirements, harsh mechanical environments or climate conditions, especially a mechanical lock that can be used as a general accessory for various industrial cabinets or power distribution cabinets. Background technique [0002] Anti-loosening reinforced multi-point mechanical locks for cabinets must have the characteristics of small size, light weight, and strong locking and fastening force. Most of the traditional mechanical locks on the market are large in size and heavy in weight, making it difficult to use them conveniently in industrial cabinets or power distribution cabinets. Even though some mechanical locks are small in size and light in weight, they cannot be used in harsh mechanical environments, climatic environments or electromagnetic environments. Compatible with environmental requirements, this type of eq...
