Technical Field

[0001] The invention relates to the technical field of fixed connection, and in particular to a fixing mechanism. Background Art

[0002] In some work situations, it is necessary to connect the device to be fixed to a fixed object such as a base. However, the rigidity of the connection using ropes and other fixing methods is insufficient, and it is difficult to avoid the relative movement of the two under impact loads. Simple rigid connection mechanisms are not adaptable enough and cannot achieve adaptive adjustment of the device to be fixed. Summary of the invention

[0003] In view of this, the present invention provides a fixing mechanism that can be adjusted in three directions and will not move due to impact loads after the device to be fixed is fixedly connected to the fixed object.

[0004] The technical solution of the present invention is: a fixing mechanism, comprising: a base, a sliding block, a pressing block and a connecting block;

The rotational cooperation between the device to be fixed, the connecting block, the pressing block and the sliding block and the sliding cooperation between the sliding block and the base can realize three-way position adjustment between the device to be fixed and the fixed object. When adjusted to the set position, the other end of the sliding block can be locked with the pressing block.

[0008] Preferably, a T-shaped groove is provided on the upper surface of the base, and a corresponding T-shaped protrusion is provided at the bottom of the sliding block. The T-shaped protrusion at the bottom of the sliding block and the T-shaped groove on the upper surface of the base are engaged with each other through concave-convex cooperation to achieve snap-in connection, and the T-shaped protrusion can slide along the T-shaped groove.

[0009] Preferably, the sliding block and the base are locked by one or more sets of bolt and nut assemblies III.

[0010] Preferably, the sliding block and the pressing block are locked by one or more sets of bolt and nut assemblies II.

[0011] Preferably, three groups of bolt and nut assemblies II are arranged between the sliding block and the pressing block.

[0012] Preferably, the three groups of bolt and nut assemblies II are arranged in a triangle.

[0013] Preferably, the sliding block is a wedge-shaped block structure, and its upper surface is an inclined surface, so that the pressing block can rotate downward relative to the sliding block.

[0014] Beneficial effects:

[0015] 1. The fixing mechanism of the present invention can be adjusted in three directions under the composite motion formed by the rotation between the four-bar linkage and the sliding cooperation between the sliding block and the base, and after the device to be fixed is connected to the fixed object, under the limiting action of the bolt and nut assembly I, it will not move due to impact load.

[0016] 2. The present invention realizes the snap connection through the concave-convex cooperation between the T-shaped protrusion and the T-shaped slide groove, which can realize the sliding cooperation between the sliding block and the base, and can also realize the upper and lower movement limiting between the sliding block and the base.

[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0021] Embodiment 1:

[0022] This embodiment provides a fixing mechanism that can be adjusted in three directions, and will not move due to impact loads after the device to be fixed is fixedly connected to the fixed object.

[0023] like Figure 1 and 2 As shown, the fixing mechanism includes: a base 1, a sliding block 2, a bolt and nut assembly I3, a bolt and nut assembly II4, a bolt and nut assembly III5, a pressing block 6, a rotating pin 7, a connecting pin 8, a connecting block 9 and a fixing pin 10.

[0024] The connection relationship of the fixing mechanism is as follows: the base 1 is fixed on the fixed object, a T-shaped slide groove is provided on the upper surface of the base 1, a corresponding T-shaped protrusion is provided at the bottom of the sliding block 2, and the T-shaped protrusion at the bottom of the sliding block 2 is matched with the T-shaped slide groove on the upper surface of the base 1, so that the sliding block 2 can slide along the T-shaped slide groove in the base 1;

[0025] When the sliding block 2 slides to a set position relative to the base 1, the sliding block 2 and the base 1 can be fixedly connected by one or more sets of bolt and nut assemblies III5, so as to be locked at the set position;

[0026] One end of the pressing block 6 is rotatably connected to one end of the sliding block 2 through a rotating pin 7, so that the pressing block 6 can rotate around the rotating pin 7. The other end of the pressing block 6 is installed with a bolt and nut assembly I3 for limiting the rotation of the pressing block 6 relative to the sliding block 2.

[0027] One end of the connecting block 9 is hinged to the middle of the pressing block 6 through a fixing pin 10, and the other end is hinged to the device to be fixed through a connecting pin 8, and the axial direction of the rotating shaft is parallel to the sliding direction of the sliding block 2. The connecting block 9 can rotate around the fixing pin 10 and the connecting pin 8 respectively, and a four-bar linkage is formed between the device to be fixed, the connecting block 9, the pressing block 6 and the sliding block 2. The fixing mechanism can realize three-way position adjustment under the composite motion formed by the rotational cooperation between the four-bar linkage and the sliding cooperation between the sliding block 2 and the base 1.

[0028] The working principle of the fixing mechanism is as follows: when the fixing mechanism moves to the set position under the compound motion, the connecting block 9 is connected to the device to be fixed through the connecting pin 8, and the sliding block 2 and the pressing block 6 are locked by one or more sets of bolt and nut assemblies II 4, and then the bolt and nut assembly 3 is adjusted to make it press against the sliding block 2 and be spaced a set distance from the sliding block 2, so as to avoid the tendency of the pressing block 6 to rotate toward the sliding block 2 around the rotating pin 7 after the pressing block 6 is locked with one end of the sliding block 2, thereby ensuring that the mechanism will not move due to impact after locking.

[0029] Embodiment 2:

[0030] On the basis of Example 1, the sliding block 2 is a wedge-shaped block structure, and its upper surface is an inclined surface, and the inclined surface is inclined from the end where the rotating pin 7 is located to the end where the bolt and nut assembly II 4 is located, thereby increasing the distance between the pressing block 6 and the sliding block 2, which is conducive to the downward rotation of the pressing block 6 relative to the sliding block 2.

[0031] Embodiment 3:

[0032] On the basis of Example 1 or 2, the sliding block 2 and the pressing block 6 are tightened by three sets of bolt and nut assemblies II4, and the three sets of bolt and nut assemblies II4 are arranged in a triangle, thereby ensuring that the fixing mechanism effectively locks the device to be fixed on the fixed object.

[0033] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
