Description

Locking device and instrument box

Technical Field

The utility model relates to a hasp technique especially relates to a locking device and instrument shelter.

Background

Instrument boxes on the market are various, and the types of lock catches used on the instrument boxes are mainly divided into two types: a snap-fit type (plastic material) and a snap-fit type (metal material).

Fig. 1 is a conventional fastening type instrument box, fig. 2 is a partial sectional view of fig. 1, the instrument box includes a cover 106 and a box 105, one of the cover 106 and the box 105 is provided with an abutting portion 104, and the other is provided with an instrument box fastening position 101, and the fastening type fastener mainly includes: a latch snap 102 and a latch lever portion 103. The locking and unlocking actions of the instrument box are completed by the friction clamping matching of the instrument box locking position 101 and the locking and buckling position 102, the locking and buckling lever part 103 is rotatably arranged on one side of the abutting part 104 far away from the instrument box locking position 101, and the abutting part 104 can abut against the instrument box locking position 101 when the cover 106 covers the opening of the box body 105.

The buckling process comprises the following steps:

(1) pressing the latch lever part 103 downwards by hand to drive the latch buckling position 102 to rotate downwards and enable the abutting part 104 and the instrument box buckling position 101 to be positioned on the inner side of the latch;

(2) when the lock catch buckling position 102 contacts the instrument box buckling position 101, the two buckling positions are rubbed, the plastic is deformed, and the hand continues to press down forcefully until the lock catch buckling position 102 presses down to the lower side of the instrument box buckling position 101;

(3) at the moment, the position of the lock catch buckling position 102 is positioned in a groove of the instrument case buckling position 101 and clamped, meanwhile, a certain pretightening force is reserved due to the squeezing relation of the contact parts, the contact parts and the instrument case buckling position 101 keep static, the abutting part 104 abuts against the instrument case buckling position 101 and is positioned on the inner side of the lock catch lever part 103, and the box body 105 is locked.

Similarly, the specific process of opening is as follows:

(1) the locking lever part 103 is pulled up by hand to drive the locking position 102 to rotate upwards;

(2) the buckling position 102 of the lock catch and the buckling position 101 of the instrument case are rubbed, and the hand continues to pull the lock catch lever part 103 until the lock catch buckling position 102 is driven to be pulled up to the upper surface of the buckling position 101 of the instrument case;

(3) at this time, the instrument box engaging portion 101 and the latch engaging portion 102 are separated from each other, so that the abutting portion 104 and the instrument box engaging portion 101 are exposed to the outside and the box body 105 can be opened.

The open state is shown in fig. 3.

The box hasp structure of another kind of frequent use is the hasp formula, and this material is mostly the metal. One type of buckle that is commonly used in the market is shown in fig. 4. The use history of the buckle has been decades, and the buckle is mostly used in the case or wooden case which is common in the past.

Both the fastening type lock catch and the hasp type lock catch have the advantages of reliability and reusability, and the popularization of the two types of lock catch switches proves the practicability in past historical application. With the progress of products, the quality and performance requirements of chassis accessories are continuously improved, and the defects of the two types of latches are exposed.

The disadvantages of the snap-lock fastener mainly lie in: 1. the service life is shortened along with the increase of the use times. Because its switch closure mode mainly relies on the friction to realize, the plastic material rubs and will lead to the fact the wearing and tearing of material for a long time certainly, causes the friction department area of contact to reduce to make the hasp detain not tight box, finally cause hasp inefficacy, the unable closure of box. 2. Because its switch closure mode mainly relies on the friction to realize, the box is stable firm enough when guaranteeing to close, and the pretightning force will be big enough to certain extent during the closure prevents that the lock department from breaking away, and this just requires frictional force big enough to can take the strength of considerable degree to overcome the friction and lock the box during the messenger's lock, so can make the user experience not good because of the considerable dynamics of the cost.

The disadvantage of the snap-on lock catch is: 1. the material is metal, and is placed for a long time and easily causes rustiness when being used outdoors, especially in a humid environment, and the service life is influenced. 2. The use mode of hasp is comparatively complicated, needs both ends cooperation during the use, has the principle of violating the simplicity and ease.

Therefore, there is a need for a latch that is easy to use, reliable, and durable to close the instrument container.
