Abstract
The utility model relates to an integrated module locking device which comprises a module body (1), a threaded rod (2), a front sliding block (3) and a rear sliding block (4). The upper end face and the lower end face of the module body (1) are respectively provided with an isosceles trapezoid block (7). An open oval through hole (8) penetrates through the isosceles trapezoid blocks (7). The threaded rod (2) penetrates through the front sliding block (3) and the open oval through hole (8) in sequence and then is connected with a threaded hole (9) in the rear sliding block (4) in a matched mode. The integrated module locking device has the advantages that a traditional independent locking device is replaced, the number of used screws and rivets is reduced, the threaded rod (2) is rotated, so that the front sliding block (3) and the rear sliding block (4) protrude out, and finally the module body (1) is locked on a case (5) with a guide groove. The integrated module locking device is compact in structure, high in structural strength, high in heat conduction efficiency, and convenient to assemble and disassemble.
Description
Technical field
The utility model relates to a kind of locking device, particularly a kind of integrated module locking device.
Background technique
Cabinet is the carrier of most of Military Electronic Equipment, along with the increase of electronic functionalities and the miniaturization of equipment, electromagnetic compatibility and heat radiation are that the structural design personnel face maximum problem, each functional cards in cabinet etc. all needs to adopt the metal shell shielding, and this type of functional cards with metal shell is called module usually.Under the prerequisite that guarantees the Military Electronic Equipment reliability, need the disassembly and assembly time of shortening heat conducting path and module as much as possible.
It is at present a large amount of that what use is all module latch device independently, be generally Wedge-type locking device, referring to " SJ 20382-2007 Wedge-type locking device standard " such Wedge-type locking device, by modes such as screw thread or riveted joints, with module, be connected, the mode be threaded connection, length requirement to screw is higher, simultaneously due to material and length of thread engagement less, easy sliding tooth; By riveting method, riveting process is had relatively high expectations, during riveted joint, due to unbalance stress, easily cause the bending of wedge type part, cause scrapping.Above two kinds of Placements, the intensity of joint all can obviously descend, and on structure, the space waste is also larger simultaneously, and the gap of joint, also can affect hot conduction.
The model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of compact structure, integrated module locking device that heat conduction efficiency is high are provided, and meets easy accessibility, safe and reliable simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of integrated module locking device, it comprises the cabinet that guide groove is installed and the module body on cabinet is installed, it also comprises screw rod, front-slider and rear slider, be respectively arranged with the isosceles trapezoid piece on the upper-end surface of described module body and lower end surface, one side of isosceles trapezoid piece offers opening shape ellipse hole, front-slider coordinates with an inclined-plane of isosceles trapezoid piece, rear slider coordinates with another inclined-plane of isosceles trapezoid piece, one end of screw rod is provided with straight groove, screw rod is successively through front-slider, opening shape ellipse hole also is connected with the tapped hole that is located at rear slider inside.
Described screw flight length is 2～2.5 times of rear slider reach.
Through-hole diameter on described front-slider equates with the minor axis length of opening shape ellipse hole.
Inclined-plane one side of described rear slider offers through hole, and the diameter of through hole is greater than the nominal diameter of tapped hole.
The utlity model has following advantage: by rotary screw, make front-slider, rear slider projection, realize module latch reaching the purpose of locking in being provided with the cabinet of guide groove.Such integrated module locking device is compact structure not only, and structural strength is high, and heat conduction efficiency is high, easy accessibility.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is screw rod;
Fig. 3 is that the isosceles trapezoid piece is fixed on the side structure schematic diagram on module body;
The structure for amplifying schematic diagram that Fig. 4 is rear slider;
In figure: 1-module body, 2-screw rod, 3-front-slider, 4-rear slider, 5-straight groove, 6-cabinet, 7-isosceles trapezoid piece, 8-opening shape ellipse hole, 9-tapped hole, 10-through hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of integrated module locking device, it comprises the cabinet 6 that guide groove is installed and the module body 1 on cabinet 6 is installed, it also comprises screw rod 2, front-slider 3, rear slider 4 and isosceles trapezoid piece 7, be respectively arranged with isosceles trapezoid piece 7 on the upper-end surface of described module body 1 and lower end surface, a ringent ellipse hole 8 runs through isosceles trapezoid piece 7, front-slider 3 coordinates with an inclined-plane of isosceles trapezoid piece 7, rear slider 4 coordinates with another inclined-plane of isosceles trapezoid piece 7, one end of screw rod 2 is provided with straight groove 5, screw rod 2 is successively through front-slider 3, opening shape ellipse hole 8 also is connected with the tapped hole 9 that is located at rear slider 4 inside.
Described screw rod 2 reaches are 2～2.5 times of rear slider 4 reaches.
Through-hole diameter on described front-slider 3 equates with the minor axis length of opening shape ellipse hole 8.
Inclined-plane one side of described rear slider 4 offers through hole 10, and the diameter of through hole 10 is greater than the nominal diameter of tapped hole 9.
By the straight groove 5 of rotary screw 2 one ends, make front-slider 3 and rear slider 4 move and form projection along the inclined-plane of the isosceles trapezoid piece 7 of module body 1, realize module body 1 is locked in cabinet 6.
