Description

Connecting device with self-locking function

Technical Field

The utility model belongs to the tool to lock field, specifically speaking especially relates to a connecting device with from locking function.

Background

The traditional locking device is mainly connected with a lock, the lock is also popular with people due to high safety, but in daily life, certain trouble is often caused to life due to too many lost keys or keys. For example, if a door cabinet in a home is locked and a key is forgotten, the lockset is easy to remove and damage; when children are small at home, some dangerous goods and flammable and fragile goods cause danger due to improper placement, and if the dangerous goods and the flammable and fragile goods are locked, the keys are too many, the time consumption is troublesome, and the dangerous goods and the flammable and fragile goods are easy to lose.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a connecting device with from locking function, it can realize the interim fixed and the locking of devices such as door cabinet, and can realize from the locking under the condition that need not the key.

In order to achieve the purpose, the utility model is realized by the following technical proposal:

the connecting device with the self-locking function comprises a lock A and a lock B, wherein the lock A comprises a frame body, fixing rings are arranged at two ends of the frame body, a suspension rod is arranged in each fixing ring, and limiting rings are arranged at two ends of each suspension rod; the lock B comprises a ring body, and a U-shaped part is arranged on the ring body; the inner diameter of the fixing ring allows the U-shaped part to pass through, and the inner space of the U-shaped part allows the limiting ring to pass through laterally.

Compared with the prior art, the beneficial effects of the utility model are that:

this application can realize two subassembly tool to lock A and tool to lock B's nestification after interlude each other through the cooperation of self structure, realizes the locking function then. The user can realize the locking and the opening of the object provided with the connecting device under the condition of not needing a key, and can improve the use pleasure of the user in the use process while efficiently and quickly using the connecting device.

Detailed Description

The technical solutions described in the present application are further described below with reference to the accompanying drawings and embodiments.

Example 1: a connecting device with a self-locking function comprises a lock A and a lock B, wherein the lock A comprises a frame body 3, two ends of the frame body 3 are provided with fixing rings 2, a suspension rod 4 is arranged inside the fixing rings 2, and two ends of the suspension rod 4 are provided with limiting rings 1; the lock B comprises a ring body 5, and a U-shaped part 6 is arranged on the ring body 5; the inner diameter of the fixing ring 2 allows the U-shaped part 6 to pass through, and the inner space of the U-shaped part 6 allows the limiting ring 1 to pass through laterally.

In the following detailed description of the locking principle and operation of the present application, it should be noted that the directional terms used in the following paragraphs, including but not limited to front, rear, left, right, outer, inner, etc., are to be construed in the context of the drawings of the specification as illustrated and should not be construed as limiting the present application.

In this application, tool to lock A include support body 3, two free ends of support body 3 weld respectively or buckle and have solid fixed ring 2, gu fixed ring 2 is airtight ring body, its internal diameter is d 2. The suspension rods 4 are placed on the two fixing rings 2, the limiting rings 1 are welded or bent at the two ends of the suspension rods 4, the limiting rings 1 are closed ring bodies, and the inner diameter of each limiting ring is d 1. The two limiting rings 1 are both positioned outside the corresponding fixing rings 2. The inner diameter d1 of the limiting ring 1 is larger than the inner diameter d2 of the fixing ring 2, so that the suspension rod 4 can be placed inside the fixing ring 2 instead of falling off.

The lock B described in this application comprises a ring 5, the ring 5 being a closed ring and a U-shaped portion 6 protruding the ring being machined on one side of the ring 5. As shown in fig. 2 and 3.

The dimensional relationship among the above-mentioned each structure is: the outer diameter d3 of the U-shaped portion 6 needs to be able to pass through in the direction of the inner diameter d2 of the fixing ring 2, and the inner diameter d5 of the U-shaped portion 6 needs to allow the stop ring 1 to pass through in the thickness direction.

In the process of combining the two, firstly respectively hold the frame body 3 and the ring body 5 by hands, insert the U-shaped part 6 into the fixing ring 2 on any side of the frame body 3, and stop when the length of the U-shaped part 6 extending out of the fixing ring 2 meets the requirement that the limiting ring 1 passes through the U-shaped part 6.

At this time, the retainer ring 1 is inserted from one side of the U-shaped portion 6 to the corresponding side through the inside of the U-shaped portion 6, and the suspension rod 4 connected to the retainer ring 1 does not interfere with the U-shaped portion 6.

After the limiting ring 1 completely passes through the U-shaped part 6, the U-shaped part 6 is withdrawn from the fixing ring 2, so that the lock A and the lock B can be locked, namely, the state shown in fig. 4 is achieved.

When it is necessary to separate the two as shown in fig. 4, the ring body 5 which has been fitted over the suspension rod 4 is lifted, and the U-shaped portion 6 of the ring body 5 is passed through the fixing ring 2 from the side of the fixing ring 2 where the suspension rod 4 is located. And stopping when the U-shaped part 6 extends out of the fixing ring 2 for a length which meets the requirement that the limiting ring 1 passes through the inner side of the U-shaped part 6.

At this moment, the limiting ring 1 is located on one side of the U-shaped portion 6, and after the limiting ring 1 penetrates through the inside of the U-shaped portion 6 from the position and reaches the corresponding side, the U-shaped portion 6 is pulled out of the fixing ring 2, so that the lock A can be separated from the lock B.

In this application, support body 3 and ring body 5 can adopt different shapes, but no matter what kind of shape is adopted to support body 3 and ring body 5, all need guarantee that the size of the solid fixed ring 2 at 3 both ends of support body is less than the size of spacing ring 1, leave the convex U type portion 6 of inwards buckling on the ring body 5, and the size relation of each part needs to satisfy narration in the above-mentioned paragraph.
