Description

Technical Field

[0001] This utility model relates to the field of safety locking technology, and in particular to a locking device for mechatronic equipment. Background Technology

[0002] Mechatronics equipment refers to equipment that integrates multiple technologies such as mechanical, electrical, and electronic control into a single device. When in use, mechatronics equipment needs to be installed on a support base. For mechatronics equipment used for a long period of time, threaded fasteners are generally inserted into the mounting holes on the mechatronics equipment and the mounting holes on the support base to connect and lock the mechatronics equipment to the support base. For mechatronics equipment used for a short period of time, which requires frequent disassembly and assembly, using threaded fasteners for connection and fixation is time-consuming and laborious during the disassembly and assembly process. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a locking device for mechatronic equipment.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] A locking device for mechatronics equipment includes a cylindrical mounting tube and a steel wire rope.

[0006] Two guide holes are provided on the bottom wall of the mounting tube, arranged radially along the mounting tube. A locking block that reciprocates along the guide hole is installed in each guide hole. The two ends of the steel wire rope are respectively fixed in the two locking blocks.

[0007] A guide mechanism is interference-fitted into the bottom opening of the mounting tube, and a compression spring is clamped between the guide mechanism and each of the two locking blocks.

[0008] A T-shaped unlocking mechanism is inserted into the top opening of the installation tube, and the middle part of the steel wire rope is installed on the unlocking mechanism;

[0009] A limiting ring is screwed to the upper outer side of the mounting tube. A pressure ring and a second compression spring are sleeved on the mounting tube between the locking block and the limiting ring. The second compression spring is sandwiched between the pressure ring and the limiting ring.

[0010] The head of the mounting tube is inserted into the mounting hole on the electromechanical integrated equipment and the mounting hole on the support base, and the pressure ring cooperates with the locking block to clamp the electromechanical integrated equipment and the support base.

[0011] The upper outer wall of the mounting tube is provided with an external thread, the axial length of which is half the total length of the mounting tube, and the limiting ring is screwed to the external thread.

[0012] The limiting ring has two protrusions extending radially along its outer side, and the two protrusions are arranged in a mirror-symmetrical manner about the center of the limiting ring.

[0013] The locking block has limiting blocks extending axially along the mounting tube at its top and bottom sides on the centripetal side.

[0014] The centrifugal side of the locking block is a curved surface that slopes outward from bottom to top.

[0015] The bottom of the centrifugal side of the locking block is located in the guide hole during the reciprocating motion of the locking block.

[0016] The locking block has a spring receiving groove in the center of its centripetal side, and one end of the compression spring is received in the spring receiving groove.

[0017] The guiding mechanism comprises, from bottom to top, a circular cover plate, a cylindrical plug, and a rectangular guide block. The cover plate, plug, and guide block are integrally formed. The bottom edge of the cover plate is rounded. The plug is interference-fitted with the bottom opening of the mounting tube. The guide block has one main guide hole and two secondary guide holes that are perpendicular to each other, and the main guide hole is connected to the two secondary guide holes. The two ends of the wire rope pass through the main guide hole and out of the two secondary guide holes respectively.

[0018] The unlocking mechanism includes a straight handle, a cylindrical guide tube, and a steel pin. The guide tube is vertically welded to the bottom of the straight handle. A circular hole communicating with the inner cavity of the guide tube is opened in the center of the straight handle. A pin hole perpendicular to the circular hole is also opened in the straight handle. The steel pin is interference-fitted into the pin hole and hooks the middle of the wire rope.

[0019] The beneficial effects of this utility model are as follows: During installation, simply pinch the limiting ring with your hand and insert the head of the mounting tube into the mounting hole on the mechatronic equipment and the mounting hole on the support base. The locking block extends out of the guide hole under the spring restoring force of the first compression spring, and the pressure ring moves towards the locking block under the spring restoring force of the second compression spring, so that the pressure ring and the locking block cooperate to clamp the mechatronic equipment and the support base. During disassembly, pinch the unlocking mechanism with your hand and pull it away from the mounting tube to retract the locking block into the guide hole. Continue to pull the unlocking mechanism away from the mounting tube until the mounting tube is pulled out from the mounting hole on the mechatronic equipment and the mounting hole on the support base. This locking device has a simple structure, is easy to install and disassemble, and is convenient for use in mechatronic equipment that is frequently disassembled and assembled.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 8 As shown, a locking device for mechatronic equipment includes a cylindrical mounting tube 1 and a steel wire rope 2. Two guide holes 11 are provided on the bottom wall of the mounting tube 1, arranged radially along the mounting tube 1. A locking block 3 is installed in each guide hole 11 and moves reciprocally along the guide hole 11. The two ends of the steel wire rope 2 are respectively fixed in the two locking blocks 3.

[0032] The top and bottom of the centripetal side of the locking block 3 are respectively provided with limiting blocks 31 extending along the axial direction of the mounting tube 1. The limiting blocks 31 prevent the locking block 3 from popping out of the guide hole under the restoring force of the compression spring 1.

[0033] The centrifugal side of the locking block 3 is a curved surface 32 that slopes outward from bottom to top. During the process of inserting the mounting tube 1 into the mounting hole on the mechatronic equipment and the mounting hole on the support, setting the centrifugal side of the locking block 3 to a curved surface 32 facilitates contact with the hole wall of the mounting hole, allowing the locking block 3 to move towards the center of the mounting tube 1.

[0034] The bottom of the centrifugal side of the locking block 3 is located in the guide hole 11 during the reciprocating motion of the locking block 3. This prevents the bottom of the locking block 3 from protruding outside the mounting tube 1 and obstructing the insertion of the locking block and the mounting tube into the mounting holes of the mechatronic equipment and the mounting holes of the support base during the insertion of the mounting tube 1 into the mounting holes of the mechatronic equipment and the mounting holes of the support base.

[0035] A guide mechanism 4 is interference-fitted into the bottom opening of the mounting tube 1. The guide mechanism 4 includes, from bottom to top, a circular cover plate 41, a cylindrical tube plug 42, and a rectangular guide block 43. The cover plate 41, tube plug 42, and guide block 43 are integrally formed. The bottom edge of the cover plate 41 is rounded. The tube plug 42 is interference-fitted into the bottom opening of the mounting tube 1. The guide block 43 has a main guide hole 431 and two secondary guide holes 432 that are perpendicular to each other. The main guide hole 431 is connected to the two secondary guide holes 432. The two ends of the steel wire rope 2 pass through the main guide hole 431 and out into the two secondary guide holes 432 respectively.

[0036] A compression spring 5 is sandwiched between the guide mechanism 4 and the two locking blocks 3 respectively; a spring receiving groove 33 is provided in the center of the centripetal side of the locking block 3, one end of the compression spring 5 is received in the spring receiving groove 33, and the other end of the compression spring 5 abuts against the side of the guide block 43. This serves two purposes: first, to prevent the compression spring 5 from slipping and separating from the locking block 3 during compression; and second, to provide a receiving space for the compression spring 5, thereby increasing the space in the mounting tube for accommodating the guide mechanism.

[0037] The head of the wire rope 2 is welded to the center of the bottom of the spring receiving groove 33, and a compression spring is placed on the wire rope.

[0038] A T-shaped unlocking mechanism 6 is inserted into the top opening of the mounting tube 1. The middle part of the steel wire rope 2 is installed on the unlocking mechanism 6. The unlocking mechanism 6 includes a straight handle 61, a cylindrical guide tube 62, and a steel pin 63. The guide tube 62 is vertically welded to the bottom end of the straight handle 61. A circular hole 611 communicating with the inner cavity of the guide tube 62 is opened in the center of the straight handle 61. A pin hole 612 perpendicular to the circular hole 611 is also opened in the straight handle 61. The steel pin 63 is interference-fitted into the pin hole 612 and hooks the middle part of the steel wire rope 2.

[0039] In this embodiment, the diameter of the steel pin 63 is 3 mm, and the diameter of the steel wire rope 2 is 1 mm. The specifications of the steel pin and steel wire rope can also be adapted to suit different usage scenarios.

[0040] A limiting ring 7 is screwed onto the upper outer side of the mounting tube 1. Specifically, an external thread 12 is provided on the upper outer side wall of the mounting tube 1, and the limiting ring 7 is screwed onto the external thread 12. The axial length of the external thread 12 is half the total length of the mounting tube 1, providing sufficient space for the position adjustment of the limiting ring 7.

[0041] A pressure ring 8 and a compression spring 9 are fitted on the mounting tube 1 between the locking block 3 and the limiting ring 7. The compression spring 9 is sandwiched between the pressure ring 8 and the limiting ring 7. When the head of the mounting tube 1 is inserted into the mounting hole on the mechatronic equipment and the mounting hole on the support, the pressure ring 8 abuts against the mechatronic equipment or the support under the spring restoring force of the compression spring 9. The top of the locking block abuts against the support or the mechatronic equipment. The pressure ring 8 and the locking block 3 cooperate to clamp the mechatronic equipment and the support.

[0042] Two protrusions 71 extending radially along the outer side of the limiting ring 7 are provided, and the two protrusions 71 are arranged in a mirror symmetrical arrangement about the center of the limiting ring 7. When adjusting the position of the limiting ring 7 on the mounting tube 1, the two protrusions 71 are pinched by hand and rotated.

[0043] When inserting the mounting tube into the mounting hole on the mechatronic equipment and the mounting hole on the support, pinch the limiting ring 7 or the protrusion 71 with your hand to press the head of the mounting tube into the mounting hole on the mechatronic equipment and the mounting hole on the support.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
