Embodiment 1

[0018] Example 1: Please refer to figure 2 , a flexible connection structure, including a first connecting piece 1, a second connecting piece 2 and a sliding piece 3, the first connecting piece 1 is provided with a counterbore 101, the second connection is provided with a mounting hole 201, the sliding The first end 302 of the member 3 is provided with a stopper 303, the stopper 303 is nested in the counterbore 101 and can slide relative to the counterbore 101, the second end 301 of the slider 3 is provided with a fastener 4 , the sliding member 3 is connected with the mounting hole 201 by an interference fit through the fastener 4 .

[0019] Assembly: the slider 3 passes through the counterbore 101 of the first connector 1, exposes the second end 301 of the first connector 1, sets the fastener 4 on the second end 301 of the slider 3, locks The fastening part 5 is locked; the fastening part 4 is pressed into the corresponding hole 101 on the second connecting part 1 by press...

Embodiment 2

[0021] Example 2: Please refer to image 3 , Figure 4 The difference between this embodiment and Embodiment 1 is that the second end 301 of the sliding member 3 is provided with a hole 304 with a cross groove 305, and the locking member 6 is a self-tapping screw, which is threaded into the hole 304. Because the self-tapping screw has a taper, the deeper the screw-in hole 304 is, the larger the opening of the cross groove 305 is, and the fastener 4 will open accordingly. With this structure, the interference force between the fastener 4 and the hole 101 can be adjusted through the screw-in length of the self-tapping screw, so as to ensure the reliability of the connection.

[0022] In the above embodiments, the fastener 4 can use an elastic element, so that the interference force when it is pressed into the hole 101 is large enough to ensure the reliability of the connection.

[0023] After adopting this movable connection structure, the hole 201 on the second connecting par...

Embodiment 3

[0024] Example 3: Please refer to Figure 5 , a delayed demoulding mold, comprising an upper mold 1 and a lower mold assembly, the upper mold 1 has a built-in cavity, the lower mold assembly is provided with a core, and the lower mold assembly also includes a lower mold 7 And the stripping plate 2, the core is arranged on the lower mold 7, the stripping plate 2 is provided with a through hole, the core passes through the through hole to match the cavity; the lower mold 7 and the stripping plate 2 is provided with a first sliding mechanism 8, the first sliding mechanism 8 enables the release plate to slide relative to the upper mold 1;

[0025] A second sliding mechanism is also provided between the stripping plate 2 and the upper mold 1, and the second sliding mechanism enables the stripping plate to slide relative to the upper mold.

[0026] The movable connecting part of the present invention is used as the second sliding mechanism of the delayed demoulding mold, wherein th...

Abstract

The invention provides a movable connecting structure. The movable connecting structure comprises a first connecting part, a second connecting part and a sliding part, a counter bore hole is designed in the first connecting part, a mounting hole is designed in the second connecting part, a stop block is arranged at a first end of the sliding part, the stop block is nested into the counter bore hole and can slide by being relative to the counter bore hole, a fastening part is arranged at a second end of the sliding part in a sleeve mode, and the sliding part is connected with the mounting hole in an interference fit mode by means of the fastening part. The movable connecting structure is simple and convenient to mount, and movement allowance of two relative movement parts can be easily adjusted.

Description

technical field [0001] The present invention relates to a movable connection structure. Background technique [0002] Please refer to figure 1 , when the existing two parts are movably connected and produce a certain distance of relative linear motion, it is usually used to drill holes on the two parts to be connected, insert bolts 3 in the holes, use nuts 4 at both ends, fuse or directly rivet, etc. Method, by leaving a certain gap in the first connecting part 1 and the second connecting part 2 to control the movement margin between the parts. When one or both of the first connecting part 1 and the second connecting part 2 are thicker, it is difficult to drill the installation holes, the bolts are not easy to fix, the movement margin is not easy to adjust, and it is easy to cause the nuts to be stuck and other non-removable situations. , resulting in inconvenient problems such as processing, installation, adjustment, and disassembly. Contents of the invention [0003] ...
