Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical connection and locking technical field, especially a kind of compression locking mechanism. BACKGROUND

[0002] In modern engineering field, reliable connection between components and stable locking play a very key role for the normal operation of equipment.

[0003] Traditional locking mechanism often adopts bolt nut connection, welding or simple buckle structure. Although bolt nut connection mode can provide higher connection strength, its installation process is complex, needs to be operated by special tool, and can significantly increase the weight of overall structure;Welding mode can realize relatively firm connection, but this connection is permanent, not detachable, and in welding process, it is prone to cause deformation, thermal damage and other problems of component, affect the performance and precision of component;Buckle structure is relatively simple and light, but its load capacity is limited, and the reliability of connection is poor, when facing harsh working conditions such as high vibration and strong impact, it is prone to looseness or even falling phenomenon, difficult to guarantee long-term stable operation of equipment. Therefore, a compression locking mechanism is needed to consider convenience, compactness and reliability. SUMMARY

[0004] In order to overcome the above technical problems of prior art, the utility model provides a compression locking mechanism, which solves the technical problem that traditional locking mechanism is difficult to consider convenience, compactness and reliability.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical scheme:

[0006] A compression locking mechanism is used for pressing and locking a pair of mounting plates into one, comprising: a connecting rod, the connecting rod is pivotally connected with the mounting plate, a pair of mounting plates are provided with corresponding missing parts corresponding to the connecting rod, when the connecting rod is located in a pair of missing parts, the connecting rod is axially connected with a pair of mounting plates;A set of limit stoppers, a set of limit stoppers are arranged between a pair of mounting plates;Compression mechanism, the compression mechanism comprises: pressure head, elastic element, the elastic element is installed on the connecting rod, the pressure head is connected with the elastic element, when the mechanism is in locking state, the elastic element drives the pressure head to abut on the side of mounting plate away from limit stopper;Trigger mechanism, the trigger mechanism is used for controlling the release of elastic element.

[0007] Based on the above structure, the principle of the compression locking mechanism is that the connecting rod is pivotally connected with the mounting plate, and the mounting plate is provided with a corresponding missing part corresponding to the connecting rod. When the connecting rod is in the missing part, the axial connection of the two mounting plates is realized. This connection mode provides a basis for subsequent compression locking, ensures the stability of the connection, and is convenient for subsequent operation. A set of limiting blocks are arranged between the two mounting plates, which can accurately limit the relative position of the mounting plates, ensure the accurate position of the mounting plates during compression locking, avoid deviation, and improve the stability and reliability of the overall structure. The elastic element in the compression mechanism is installed on the connecting rod and connected with the pressing head. In the locked state, the elastic element drives the pressing head to abut against the side of the mounting plate away from the limiting block, and the elastic force is used to realize the tight compression of the mounting plate, so as to ensure the adhesion degree between the mounting plates and enhance the stability of the connection. The trigger mechanism is used to control the release of the elastic element, so that the unlocking operation of the whole compression locking mechanism is controllable, and when the mounting plates need to be separated, the locking state can be smoothly released.

[0008] Further, the connecting rod and the mounting plate are pivotally connected, and the torsional elastic element is arranged at the pivotally connected position. The torsional elastic element ensures that the connecting rod is in a folded state. As a preferred solution of the present application, the connecting rod of the compression locking mechanism of the present application can automatically remain folded when the mounting plate locking operation is not performed, thereby saving space, facilitating the storage and storage of the whole mechanism, and improving the space utilization efficiency and portability of the mechanism. When the compression locking mechanism is ready to be used, the torsional elastic element makes the connecting rod in a folded state in advance, so that the operator does not need to manually adjust the connecting rod to a specific initial position, thereby simplifying the operation process, improving the convenience of use, and reducing the possibility of operation errors.

When the mechanism is in a locked state, the first block and the second block are axially connected. As a preferred solution of the present application, the first block and the second block of the compression locking mechanism of the present application are axially connected when the mechanism is in a locked state, which can limit the two mounting plates and prevent the two mounting plates from rotating relative to each other, thereby ensuring the stability and reliability of the overall structure during use. In addition, the first block and the second block can also play a guiding role during installation. The operator can accurately place the two mounting plates in the appropriate position by observing the butt joint of the first block and the second block, thereby improving the installation efficiency.

As a preferred scheme of the application, the first defect and the second defect are arranged on a pair of mounting plates, which ensures that the connecting rod can be accurately positioned; the supporting part on the inner side wall of the first defect is closely matched with the contraction section on the connecting rod, the width of the contraction section is adapted to the spacing of the supporting part, so that the supporting part can stably support the connecting rod, effectively preventing the connecting rod from moving or shaking in the working process, and the operator can easily align the contraction section of the connecting rod with the supporting part and smoothly install it, greatly simplifying the installation process and improving the assembly efficiency.

As a preferred scheme of the application, the adjusting part is threadedly connected with the sleeve, by rotating the adjusting part, the position of the adjusting part on the sleeve can be changed, so as to adjust the compression degree of the elastic member, which enables the operator to control the pressure applied by the pressing head to the mounting plate according to actual needs, so as to adapt to different mounting plate materials, thicknesses or connection tightness requirements, and to ensure that reliable compression effect can be achieved under various working conditions; the elastic member is sleeved outside the sleeve, and the two ends of the elastic member are respectively axially abutted with the pressing head and the adjusting part, which can effectively transmit the elastic force of the elastic member to the pressing head, and ensure that the mounting plate is continuously and stably pressed in the locked state.

[0012] Further, the compression locking mechanism in the application, the trigger mechanism includes: a Z-shaped trigger part, an activation part, the Z-shaped trigger part is rotationally installed on the connecting rod, the moving shaft is provided with a notch adapted to the end of the Z-shaped trigger part, when the end of the Z-shaped trigger part is located in the notch, the moving shaft is positioned on the connecting rod, and the activation part is arranged at the end of the Z-shaped trigger part away from the moving shaft. When the Z-shaped trigger part contacts with the activation part, the end of the Z-shaped trigger part near the moving shaft is separated from the notch. As a preferred scheme of the application, the above trigger mechanism provides a simple unlocking method, by setting the activation part, the unlocking operation of the moving shaft can be realized, and then the pressure of the elastic member is released, so that the pressing head is pressed and locked to the mounting plate
