[0030] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the technical solutions in the utility model embodiments will be clearly and completely described below with reference to the drawings in the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0031] The utility model embodiment provides a kind of lock structure, including mounting plate, half tooth rivet post and lock nut;Mounting plate is the mounting plate of element, half tooth rivet post is set on mounting plate, half tooth rivet post is eccentric with support screw, so that in screwing lock nut, further make support screw and half tooth rivet post closely adhere, reach the disassembly force of increasing support screw, when the disassembly force required increases, when the screw structure connected by support screw is disassembled, then it is not easy to drive support screw to rotate.
[0032] As Figures 1 to 5 As shown in the drawing, mounting plate 1 is provided with lock hole 11 for passing through support screw 4, the hole diameter of lock hole 11 is same or similar with the outer diameter of support screw 4, so that support screw 4 can normally pass through lock hole 11, and there is no excessive gap between the outer wall of support screw 4 and the inner wall of lock hole 11.
[0033] For example, mounting plate 1 is the mounting plate 1 of processor module, mounting plate 1 is superimposed with mainboard, that is, one side of mainboard is central processing unit (CPU), and the other side is mounting plate 1, and the lock structure can be used for locking and assembling processor module, and effectively increasing the disassembly force of support screw 4.
[0034] Mounting plate 1 includes front and back, wherein, the side where half tooth rivet post 2 is defined and set is front, then the other side is back, half tooth rivet post 2 is located on one side of lock hole 11, and support screw 4 is arranged side by side with half tooth rivet post 2 after passing through lock hole 11, wherein, the outer surface 22 of half tooth rivet post 2 includes external thread, for connecting lock nut 3, that is, the axis of lock nut 3 coincides with the axis of half tooth rivet post 2;And in the utility model embodiment, the axis of support screw 4 is located on one side of half tooth rivet post 2 after passing through lock hole 11, support screw 4 and half tooth rivet post 2 are eccentric, the straight line distance range between the axis of half tooth rivet post 2 and lock hole 11 and support screw 4 is 2-5 mm;When lock nut 3 is screwed on half tooth rivet post 2, support screw 4 will be extruded by lock nut 3 and close to half tooth rivet post 2, so that the two are closely matched. Specifically:
[0035] The inner surface 21 of the half-tooth rivet column 2 is used to be attached with the support screw 4, when the support screw 4 passes through the lock hole 11, and the edge position of one side of the support screw 4 is attached with the inner surface 21 of the half-tooth rivet column 2, but at this time, the two are not interfered, and there is no relative force. When the locking nut 3 is screwed with the external thread, the inner wall of the locking nut 3 is used to press the support screw 4 and the inner surface 21 of the half-tooth rivet column 2, and when the locking nut 3 is screwed in place, the support screw 4 is fully close to the inner surface 21 of the half-tooth rivet column 2, so as to ensure the effect of close cooperation between the two.
[0036] When the disassembly operation is needed, the locking nut 3 is unscrewed first, and then the mounting plate 1 and the support screw 4 are sequentially disassembled; and when the screw structure connected with the support screw 4 needs to be individually screwed, the screw structure is screwed by means of a tool, and the torque required for screwing the screw structure is less than the disassembly force of the support screw 4, so that the support screw 4 is not simultaneously driven when the screw structure is screwed, and the stability of the mounting plate 1 structure is ensured.
[0037] With reference to Figures 1 to 5 In the embodiment of the utility model, the inner surface 21 of the half-tooth rivet column 2 is arc surface, when the locking nut 3 is screwed with the external thread, the support screw 4 is attached with the arc surface part.
[0038] When the inner surface 21 is arc surface, the contact surface of the arc surface and the support screw 4 is relatively larger, when the locking nut 3 is screwed, the interference amount of the support screw 4 and the arc surface is larger, and the close degree of the connection between the two is improved, and the disassembly force of the support screw 4 is larger.
[0039] For example, the curvature of the arc surface is the same as the curvature of the support screw 4, when the locking nut 3 is screwed with the external thread, the arc surface is covered on the outer side of the support screw 4, and under the same curvature, the support screw 4 and the arc surface can be fully interfered.
[0040] For example, the curvature range of the arc surface is not less than 180 degrees, and the arc surface covers at least half of the support screw 4, so as to ensure the contact area of the support screw 4 and the arc surface.
[0041] With reference to Figures 1 to 5 In the embodiment of the utility model, the inner thread of the locking nut 3 is used to be attached with the outer edge of the support screw 4, when the locking nut 3 is screwed with the external thread, the inner thread of the locking nut 3 is used to apply pressure to the outer edge of the support screw 4.
[0042] On the outer edge of the support screw 4, one side is attached with the inner surface 21, and the other side can be attached with the inner wall (inner thread) of the locking nut 3, so that the locking nut 3 can apply force to the support screw 4. In addition, the structure of the locking nut 3 can be changed, so that the force applied by the locking nut 3 to the support screw 4 gradually increases, for example, the diameter of the inner thread of the locking nut 3 gradually decreases, and the structure is conical.
[0043] For example, the locking force range applied by the locking nut 3 and the half-dental rivet post 2 to the support screw 4 is 9kgfcm to 10kgfcm.
[0044] The utility model embodiment provides a locking structure, including mounting plate 1, support screw 4, half-dental rivet post 2 and locking nut 3, mounting plate 1 includes lock hole 11, and support screw 4 includes the screw rod structure for passing through lock hole 11, half-dental rivet post 2 is located at the front of mounting plate 1, and the outer surface 22 of half-dental rivet post 2 includes external thread, and the inner surface 21 of half-dental rivet post 2 is used to be combined with screw rod structure, and the axis of half-dental rivet post 2 is not coincident with the axis of lock hole 11 and support screw 4, and the axis of locking nut 3 is coincident with the axis of half-dental rivet post 2, when locking nut 3 is screwed with external thread, locking nut 3 inner wall is used to extrude screw rod structure and the inner surface 21 of half-dental rivet post 2 abut.

[0047] And the locking structure exerts greater dismounting force on the CPU support screw 4, so that when the heat dissipation module is dismounted alone, the screw structure of the heat dissipation module cannot drive the CPU support screw 4 to rotate synchronously, and the stability of the CPU support can be maintained in the double -deck structure.
[0048] For example, the dismounting force of the CPU support screw 4 is about 10Kgfcm by using the locking structure provided by the utility model embodiment, and the dismounting force of the screw structure of the heat dissipation module is 4.5kgfcm to 6.5kgfcm, so that when the screw structure of the heat dissipation module is dismounted, the torque of the screw structure cannot drive the CPU support screw 4 to rotate, thereby ensuring the stability of the installation of the CPU support screw 4.
