After the data memory card is inserted into the chassis clamping groove, the cam 7 is manually shifted to rotate, the upper wedge-shaped pressing block 9 can be driven to move downwards, and the middle wedge-shaped pressing block 10 is pushed to slide, so that the middle wedge-shaped pressing block 10 and the chassis clamping groove wall are in interference fit, and locking of the data memory card is realized. When the data storage card is in a locking state, a gap does not exist between the data storage card and the chassis clamping groove, so that heat of the data storage card is mainly radiated through heat conduction, and compared with heat radiation of a traditional data storage card, the heat radiation efficiency of the data storage card is higher. And in a high-magnitude vibration environment, the data storage card and the chassis clamping groove are tightly attached and cannot move, so that the stability and the reliability of data transmission are improved.
Specifically, the supporting bar 11 is fixedly connected with the housing 2, as shown in fig. 6 and 7, two sides of the supporting bar 11 perpendicular to the housing 2 and including long sides are provided with bosses 16 along the axial direction, and the upper wedge-shaped pressing block 9, the middle wedge-shaped pressing block 10 and the lower wedge-shaped pressing block 12 are provided with stop blocks 17 in fit connection with the bosses 16. The sides of the upper wedge-shaped pressing block 9, the middle wedge-shaped pressing block 10 and the lower wedge-shaped pressing block 12 facing the shell 2 are preferably opening surfaces, so that the supporting bar 11 is conveniently fixed on the shell 2 through bolts. The middle wedge-shaped pressing block 10 can horizontally displace relative to the supporting bar 11 during movement, and the boss 16 and the stop block 17 can prevent the middle wedge-shaped pressing block 10 from being separated from the supporting bar 11 along the radial direction during movement. The boss 16 and the stopper 17 can also prevent the opening surfaces of the upper wedge-shaped pressing block 9 and the lower wedge-shaped pressing block 12 from being accidentally separated from the supporting bar 11.
The cams 7 of the two locking bars are preferably connected by a handle 6; the handle 6 is in contact with the housing 2 in the locked state; the side of the housing 2 in contact with the handle 6 is provided with a groove. Providing the recess prevents fingers from interfering with the housing 2 and thereby making the handle 6 inconvenient to grasp. The handle 6 is arranged to be more convenient for manually driving the cam 7 to rotate, an operator can complete the insertion and extraction, locking and unlocking of the data memory card by one hand, and the operation is convenient. Two cams 7 are preferably symmetrically arranged on one first spring assembly 18, so that the stress points of the upper wedge-shaped pressing block 9 are uniformly distributed, and the movement of the upper wedge-shaped pressing block is smoother.
Referring again to fig. 5, both ends of the supporting bar 11 are provided with blind holes; the first spring assembly 18 includes a cylindrical pin with a spring sleeved on an outer wall thereofPartially inserting into one of the blind holes; the second spring assembly 13 comprises an adjusting bolt 14, the outer wall of which is sleeved with a spring, and the adjusting bolt 14 is in threaded connection with the other blind hole.

The pretensioning force of the springs in the second spring assembly 13 can be adjusted by rotating the adjusting bolt 14, so that the locking and unlocking moment of the handle 6 and the locking force of the locking device 1 are adjusted. The greater the preload of the second spring assembly 13, the greater the thrust required to compress the same displacement, and the greater the torque required to rotate the cam 7, the more forceful it is to move the handle 6 ； At the same time, the higher the pressure of the upper wedge-shaped pressing block 9 and the lower wedge-shaped pressing block 12 on the middle wedge-shaped pressing block 10 is, the higher the pressure between the middle wedge-shaped pressing block 10 and the clamping groove of the case is, and therefore the higher the locking force of the locking device 1 is.
In the scheme, the cushion block 8 is preferably arranged between the upper wedge-shaped pressing block 9 and the cam 7, and the cushion block 8 is in sliding connection with the first spring assembly 18, so that the cam 8 can be prevented from wearing the upper wedge-shaped pressing block 9. The adjusting bolt 14 is preferably an outer hexagonal bolt, and one surface of the head portion is attached to the surface of the housing 2, so that the locking force of the locking device is prevented from being lowered due to loosening during long-term use.
The locking device 1 of this scheme theory of operation does:
1. when the lock is performed, the handle 6 is rotated to drive the cam 7 to rotate, so that the long diameter of the cam 7 presses against the upper wedge-shaped pressing block 9, and the springs in the first spring assembly 18 are compressed under pressure, so that the upper wedge-shaped pressing block 9 moves downwards. The upper wedge-shaped pressing block 9 presses the middle wedge-shaped pressing block 10, and the middle wedge-shaped pressing block 10 slides along an inclined contact surface between the upper wedge-shaped pressing block and the middle wedge-shaped pressing block, so that the middle wedge-shaped pressing block 10 can downwards displace and simultaneously generate horizontal displacement, the middle wedge-shaped pressing block 10 is tightly attached to a clamping groove of a case, and pressure is generated, so that a tight connection is obtained. The displacement of the upper wedge press 9 can be transferred to the lower wedge press 12 and compress the springs of the second spring assembly 13. The movement tracks of the upper wedge-shaped pressing block 9, the middle wedge-shaped pressing block 10 and the lower wedge-shaped pressing block 12 during locking can be referred to as fig. 4.
2. When unlocking, the handle 6 is rotated to drive the cam 7 to rotate to the side of the cushion block 8 in a short diameter, the pressure applied to the first spring assembly 18 disappears, the first spring assembly 18 rebounds, and the elastic force of the spring drives the upper wedge-shaped pressing block 9 to move upwards to the original position. Similarly, the second spring component 13 rebounds and drives the lower wedge-shaped pressing block 12 to move upwards, and the lower wedge-shaped pressing block 12 pushes the middle wedge-shaped pressing block 10 to move along the inclined contact surface between the two, so that the middle wedge-shaped pressing block 10 generates horizontal displacement and is not tightly attached to the chassis clamping groove. At this time, the data storage card can be taken out from the case card slot by one hand by holding the handle 6.
