Description

Technical Field

[0001] The utility model relates to the technical field of edge locking, in particular to an edge locking mechanism. Background Art

[0002] A mattress is an item that is placed between the human body and the bed to ensure that consumers get a healthy and comfortable sleep. Mattresses are made of a variety of materials, and mattresses made of different materials can bring different sleeping effects to people. With the continuous advancement of material civilization and technological processes, the types of mattresses used by modern people are gradually becoming diversified.

[0003] During the processing of the mattress, the mattress needs to be edge-locked on all sides. The tools for edge locking are usually a set of sewing machines and a large machine tool board. The sewing machine is located on one side of the bed board. Then the mattress is placed on the bed board as a whole so that the edge of the bed contacts the sewing machine to complete the edge locking. After the edge locking on one side of the mattress is completed, the mattress is usually rotated vertically and then the edge locking process continues.

[0004] However, the existing device does not position the edge of the mattress, so that the mattress is prone to tilt during the edge locking process, causing edge locking deviation, which in turn affects the edge locking effect. Therefore, we propose a locking mechanism to solve the above problem. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art in the background technology and proposes a locking mechanism.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] Preferably, both ends of the connecting shaft are provided with limit blocks, and both upper and lower ends of the movable slot are provided with limit slots, and the limit blocks extend into the limit slots;

[0012] When the mattress rotates and contacts the rotating roller, the rotating roller drives the connecting shaft and the limit block to move inside the limit groove, so that the rotating roller is buffered to avoid excessive squeezing of the rotating roller after the mattress rotates, causing deformation.

[0013] Preferably, a fixed shaft rod is arranged inside the limiting groove, and the limiting block is sleeved on the outside of the fixed shaft rod;

[0014] The movement of the limit block can be made more stable, thereby preventing the limit block from shaking or falling off.

[0015] Preferably, a support spring is sleeved on the outside of the fixed shaft, one end of the support spring is fixedly connected to the limit block, and the other end of the support spring is fixedly connected to the inner wall of the limit groove;

[0016] After the rotating roller moves, the limit block can be supported by the support spring, so that the limit block drives the rotating roller to recover, so that the rotating roller can work normally.

[0017] Preferably, a mounting seat is provided at the bottom end of the mounting support frame, a rotating screw is provided at the end of the mounting seat, and the sliding block is sleeved on the outside of the rotating screw;

[0018] The limit baffle can be moved as a whole, so that the limit baffle can be adjusted according to the required edge locking position of the mattress, and can be used for mattresses with different edge locking positions.

[0020] The rotating block can be rotated to drive the rotating screw to rotate, and the rotating screw drives the limit baffle to move. At the same time, the limit baffle can be positioned by the self-locking of the bolt, which is easy to use.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The utility model places the mattress above the mounting support frame so that the side of the mattress contacts the limit baffle. At the same time, the position of the limit baffle can be adjusted to change the contact position between the mattress and the edge locking machine body. Subsequently, the limit baffle can make the mattress more stable during the movement and avoid the tilting of the edge locking.

[0023] 2. After the edge locking of one side of the mattress is completed, the utility model will rotate the mattress, and then the other side of the mattress will rotate and act on the top of the rotating roller. The rotating roller can provide buffering to avoid damage to the rotating roller. At the same time, the rotating roller can reduce the friction between the mattress and the mattress, so that the movement of the mattress is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, limiting grooves 12 are provided at the upper and lower ends of the movable slot 9, so that the limiting block 13 extends to the inside of the limiting groove 12, and a fixed shaft 14 is provided inside the limiting groove 12, and then the limiting block 13 is sleeved on the outside of the fixed shaft 14, and a support spring 15 is sleeved on the outside of the fixed shaft 14, and one end of the support spring 15 is fixedly connected to the limiting block 13, so that the other end of the support spring 15 is fixedly connected to the inner wall of the limiting groove 12.

[0031] For a detailed description of the sliding block 5 in this embodiment, please refer to Figure 3 and Figure 4 A mounting seat 6 is provided at the bottom end of the mounting support frame 1, and then a rotating screw 7 is provided at the end of the mounting seat 6, and the sliding block 5 is sleeved on the outside of the rotating screw 7, and then the end of the rotating screw 7 passes through one group of the mounting seats 6 and extends to the outside, and a rotating block 8 is provided at the end of the rotating screw 7.

[0032] Working principle: When the utility model is in use, the mattress is placed above the mounting support frame 1 so that one side of the mattress comes into contact with the limit baffle 3. At this time, the rotating block 8 can be rotated according to the position where the mattress needs to be locked, so that the rotating block 8 drives the sliding block 5 to move, and the sliding block 5 drives the limit baffle 3 to move, so that the limit baffle 3 supports one side of the mattress, changes the distance between the mattress and the locking machine body 2, and then pushes the mattress so that the locking machine body 2 completes the locking of one side of the mattress.

[0033] After one side of the mattress has been edge-locked, the mattress needs to be rotated so that the other side of the mattress comes into contact with the limit baffle 3. At this time, the mattress squeezes the rotating roller 11, so that the rotating roller 11 slides inside the limit groove 12 through the connecting shaft 10 and the limit block 13, and then recovers through the support spring 15, which can buffer the rotating roller 11 and avoid damage and deformation caused by excessive impact force. At the same time, the mattress comes into contact with the rotating roller 11, which can reduce the friction between the mattress and the mattress, making the movement of the mattress more convenient.
