For example, the first to-be-installed piece 2 may be a main board, a main board bracket, etc. in the electronic device, the second to-be-installed piece 3 may be a casing of the device or a structural member connected with the casing, such as a chassis, a chassis base, etc., and the first to-be-installed piece 2 and the second to-be-installed piece 3 may be specifically indefinite, and may be any two structural members that need to be fixedly connected by a latch module. The latch module in this embodiment includes a fixing member 1, a first connecting component and a second connecting component, wherein the fixing member 1 is mounted on a first member to be mounted 2, the first connecting component is mounted in the fixing member 1, and two ends of the first connecting component extend out of the fixing member 1, for example, two ends of the first connecting component extend out of the fixing member 1 correspondingly. Specifically, the first connecting component has a first end and a second end, and the first end extends into the second to-be-installed part 3 after extending out of the fixing part 1 so as to be connected with the second to-be-installed part 3, so that the first to-be-installed part 2 is connected with the second to-be-installed part 3, and the first to-be-installed part 2 is limited on the second to-be-installed part 3. For the second end of the first connecting component, the second connecting component is connected with the second end of the first connecting component, and the second connecting component can prevent the first connecting component from slipping out of the fixing piece 1, so that the first part to be installed 2 and the second part to be installed 3 can be stably connected based on the first connecting component and the fixing piece 1.

Based on the disclosure of the above embodiment, it can be known that the beneficial effects of the present embodiment include that the fixing piece 1 is disposed on the first to-be-installed piece 2, the first connecting component is installed in the fixing piece 1, and two ends of the first connecting component respectively extend out of the fixing piece 1, wherein the first end is used for extending into the second to-be-installed piece 3, so that the first to-be-installed piece 2 is limited on the second to-be-installed piece 3. The second connecting component is then installed on the second end of the first connecting component 11 set to prevent the first connecting component from sliding out of the fixing component 1, so that the first to-be-installed component 2 and the second to-be-installed component 3 can be stably connected. The bolt module of this embodiment simple structure, easily preparation, and the equipment is convenient, and follow-up installation is maintained of being convenient for, and small in size occupies little installation space moreover, supports electronic equipment's slim simplification design.

Specifically, as shown in fig. 1 and 3, the fixing member 1 in the present embodiment has a receiving chamber 4, and the receiving chamber 4 penetrates through the fixing member 1, for example, the fixing member 1 may be cylindrical, or may be a square cylinder or a cylinder with a cross section of other shapes, where the cylinder of the fixing member 1 is in a central control shape, and two ends of the cylinder are penetrated. The first connecting component is installed in the accommodating chamber 4, and two ends of the first connecting component respectively extend out of the accommodating chamber 4, for example, the first connecting component is installed in the hollow cylinder body, and two ends of the first connecting component extend out of the cylinder body.

In this embodiment, in order to connect the first to-be-installed part 2 with the fixing part 1, a connection hole is formed in the first to-be-installed part 2, one end of the fixing part 1 is provided with a circle of protruding edge 5, for example, the fixing part 1 extends horizontally and outwards towards one end of the first to-be-installed part 2 to form the circle of protruding edge 5, or an annular part can be independently sleeved on the fixing part 1 to form the circle of protruding edge 5 based on the annular part, which is not unique in specific mode, that is, the protruding edge 5 can be integrally formed with the fixing part 1, or can be independently arranged. One end of the fixing piece 1 with the convex edge 5 stretches into the connecting hole of the first piece 2 to be installed and is clamped and fixed with the outer edge of the connecting hole through the convex edge 5.

For example, the first part to be mounted 2 is a motherboard bracket in an electronic device, and is used for mounting and fixing a motherboard, and the motherboard may be located on the motherboard bracket to form a whole. Of course, the first member to be mounted 2 may be a main board, and is not particularly limited. The main board support is mounted on the second to-be-mounted part 3, and the second to-be-mounted part 3 can be, for example, a chassis or a chassis base of an electronic device, that is, the main board and the main board support are mounted on the chassis or the chassis base through the first connecting component and the fixing part 1. When the fixing piece 1 is installed, connecting holes can be correspondingly formed in the main board and the main board support, then the main board and the main board are sleeved outside the fixing piece 1 through the corresponding connecting holes, and one board surface of the main board support is abutted against and clamped with one circle of convex edge 5 of the fixing piece 1.

Alternatively, in practical application, the flange 5 may be an annular structure with a plane at least facing the first member to be mounted 2, or may have another shape, such as a stepped annular structure. That is, a flange 5 having a stepped surface may be provided at the end of the fixing member 1, and specifically, two layers of flanges 5 that cooperate to form a stepped shape may be provided. Meanwhile, the surface of the first part to be mounted 2, such as the surface of the main board or the main board bracket, which is abutted against the surface of the stepped convex edge 5, also needs to be provided with a stepped shape matched with the structure of the convex edge 5 for being abutted against and clamped with the convex edge 5 in a matched manner. So set up, can effectively avoid mounting 1 at the direction activity of perpendicular mainboard face, increase the area of contact between mounting 1 and first piece 2 of waiting such as mainboard or mainboard support, promote the contact and lean on the power, increase and connect the compactness.

Of course, the provision of the flange 5 in a generally annular step shape is not the only option, but it is also possible to provide the flange 5 in a step shape on at least one side facing the first member to be mounted 2, and at the same time, to change the shape of the step, such as to make the outer edge of the step in a zigzag shape, a curve shape, a wavy shape, or the like. The number of steps is also not limited, and two steps may be used, or more steps may be provided. Likewise, the main board or the main board holder to be mounted also needs to be matched with the structure of the flange 5, i.e. a matching structure is provided to achieve the connection with the first to be mounted 2. Alternatively, a plurality of limit protrusions may be provided on a surface of the flange 5 facing the first member to be mounted 2, and the protrusions may be not unique in structural shape and number, such as circular protrusions, rectangular protrusions, bar-shaped protrusions, and the like. The protrusions may be arranged on the surface of the flange 5, for example, in an array, and the protrusions are combined to form a rectangle, a circle, or a plurality of concentric rectangles, circles, or the like, and the grooves are disposed on the corresponding protrusions on the first part to be mounted 2, such as the main board or the main board support, so as to realize the matching engagement between the first part to be mounted 2 and the flange 5.

Further, the first connecting component in the present embodiment has elasticity, and can move relative to the fixing piece 1, that is, the first connecting component can move in the accommodating chamber 4 to generate elastic force. When the second end of the first connecting component is subjected to external force of drawing type, for example, when the first connecting component is pulled out of the fixing piece 1, the first connecting component can offset the external force based on the elastic force, so that the first connecting component is stably limited in the accommodating chamber 4. Moreover, based on this elastic force, it is possible to ensure that the first connection assembly is positionally stable with respect to the mount 1, i.e. stably restrained in the housing chamber 4, even when not subjected to a pulling force.

Specifically, the first connecting component comprises a connecting pin 6 and an elastic piece 7, the elastic piece 7 can be a spring, the connecting pin 6 is in a rod shape, the elastic piece 7 is sleeved outside the connecting pin, the connecting pin 6 carries the elastic piece 7 to be penetrated in the accommodating cavity 4 in the fixing piece 1 and is limited in the accommodating cavity 4 through the elastic piece 7, and two ends, namely a first end and a second end, of the connecting pin 6 extend out of the accommodating cavity 4 respectively and are connected with the second connecting component and the second piece to be installed 3 respectively, and the ground elastic force is generated by the elastic piece 7.

With continued reference to fig. 4, in this embodiment, the connecting pin 6 is provided with a first limiting protrusion 8, for example, a first limiting protrusion 8 is provided adjacent to the first end of the connecting pin 6, and the first limiting protrusion 8 is located in the accommodating chamber 4, which may specifically be a ring of protruding edges, that is, annular protruding edges. The second end of the accommodating chamber 4 or the fixing piece 1 facing the first connecting component is provided with a second limiting protrusion 9, and the second limiting protrusion 9 may also be a ring-shaped protruding ridge, for example, the second limiting protrusion 9 is formed by extending in a horizontal box of the inner wall of the accommodating chamber 4, or may be formed by extending horizontally inwards of the fixing piece 1 facing one end of the second connecting component, that is, the second limiting protrusion 9 may be located in the accommodating chamber 4, or may be located at the edge of the chamber, or may be the end of the fixing piece 1, specifically but not exclusively. The second limit projection 9 is preferably located at the end of the fixing element 1 in this embodiment. The second limiting protrusion 9 is disposed at any position, surrounds the connecting pin 6, and has a certain gap with the outer wall thereof, so as to facilitate the installation and the disassembly between the connecting pin 6 and the fixing member 1. Likewise, the first limiting protrusion 8 is preferably adjacent to the inner wall of the accommodating chamber 4, i.e. there is a gap therebetween, but the gap is smaller than the gap between the second limiting protrusion 9 and the connecting pin 6, so as to ensure the limitation of the elastic member 7. The two ends of the elastic piece 7 are respectively propped against the first limiting bulge 8 and the second limiting bulge 9, namely are respectively and stably sleeved outside the connecting pin 6 through the first limiting bulge 8 and the second limiting bulge 9 and are positioned in the accommodating cavity 4.

Further, in this embodiment, after the first end of the connecting pin 6 extends out of the fixing element 1, the first end of the connecting pin 6 may be connected with the second to-be-installed element 3 through plugging, screwing or other connecting elements 11, and the first end of the connecting pin 6 may be provided with a plug, an external thread, a connecting hole or the like according to an actual connection manner, and the second to-be-installed element 3 may be provided with a plugging slot, a threaded hole, or the connecting element 11 or the like according to an actual connection manner. For example, a socket or a socket hole may be disposed on the second to-be-mounted member 3, a connection portion such as a cross groove is disposed on the end face of the first end of the connection pin 6 toward the pin, and after the connection pin 6 is inserted into the socket or the socket hole through the first end, the connection portion such as the cross groove may be clamped with a structure disposed in a matching manner such as a cross protrusion at the bottom of the socket groove, or connected through a cross connection bolt penetrating through the socket hole or the socket groove, so as to cooperate with the fixing member 1 to achieve an effect of stably connecting the first to-be-mounted member 2 with the second to-be-mounted member 3. Of course, the structure of the connection pin 6 to the second member to be mounted 3 is not unique, and other types of connection structures are also possible. If the connecting part is not cross-shaped, the connecting part can be m-shaped, T-shaped and the like.

Optionally, as shown in fig. 6 and 7, in this embodiment, a plug hole is disposed at a position of the second part to be installed 3 corresponding to the first part to be installed 2 where the connecting hole is disposed, the hole wall of the plug hole extends toward the connecting hole to form a hollow boss, and the first end of the connecting pin 6 is inserted into the plug hole, and the boss is located below the flange 5 of the fixing part 1 and is adjacent to the flange 5, or is abutted to the flange 5, that is, the flange 5 is limited between the first part to be installed 2 and the boss of the second part to be installed 3, so that the fixing part 1 can be limited more stably, and is not easy to separate from the first part to be installed 2, or shake in the axial direction relative to the first part to be installed 2, and is not separated from the first part to be installed 2 when the first connecting component such as the connecting pin 6 or the fixing part 1 itself receives the pulling force.

Further, as further shown in fig. 6 and 7, the second connecting component and the connecting pin 6 in the present embodiment are detachably connected to the ends of the first member to be mounted 2 and the second member to be mounted 3 facing away from each other. That is, the second connection assembly is detachably connected to the second end of the connection pin 6 to facilitate the installation or removal of the latch module.

For example, the second connecting component may be detachably connected to the connecting pin 6 in a pluggable manner, or may be detachably connected to the connecting pin 6 by a detachable connecting piece 11, such as a bolt, or may be detachably connected to the connecting pin 6 by a fastening structure or by a threaded connection, or the like, which is not the only manner. The second connecting component in this embodiment is provided to prevent the connecting pin 6 from moving axially in a direction approaching the first member to be mounted 2 and the second member to be mounted 3 and slipping out of the fixing member 1.

Specifically, the second connecting component in this embodiment includes a connecting piece 11 detachably connected to the connecting pin 6, and a handle 10 installed at an end of the connecting pin 6 through the connecting piece 11, where the handle 10 is detachably connected to the connecting piece 11. For example, the handle 10 is sleeved on the connecting pin 6 and is fixed by the connecting piece 11, or the handle 10 is detachably connected with the connecting piece 11, and the connecting piece 11 carries the handle 10 to be connected with the connecting pin 6. Wherein the handle 10 or the combination of the handle 10 and the connecting piece 11 needs to be propped against the end of the corresponding fixing piece 1 or the second limit protrusion 9 on the fixing piece 1 to provide supporting force/counter-pulling force for the connecting pin 6, so as to ensure that the connecting pin 6 cannot slide out of the fixing piece 1 along the axial direction of the connecting pin 6.

As shown in connection with fig. 4, the second end of the connecting pin 6 in this embodiment is provided with a connecting structure for mating connection with the connecting member 11. The connecting structure can be a threaded counter bore, the connecting piece 11 is a bolt, and the connecting piece 11 and the connecting pin 6 are detachably connected through threads. Or, the connecting structure is a counter bore with elastic bulges, the connecting piece 11 is a structural piece with a T-shaped longitudinal section, and comprises a connecting cap and a rod body connected with the connecting cap, and the rod body is used for being inserted into the counter bore. The rod body is provided with a notch, the elastic bulge is extruded when the rod body slides into the counter bore, and the elastic bulge can relatively slide to a position corresponding to the notch along with the continuous movement of the rod body into the bore, so that the rod body slides into the notch to realize clamping. And the sliding guide surface can be matched between the notch and the elastic bulge so that the elastic bulge and the notch relatively move along with the extension and extension of the rod body relative to the counter bore, the elastic bulge can be ensured to smoothly slide into and slide out of the notch, and the connection and separation between the rod body and the counter bore are realized. When connection structure is the screw hole, the degree of depth of screw hole is not limited, and when connection structure is the elastic bulge, the elastic bulge is indefinite with the setting quantity of notch, and specific setting position is indefinite, and a plurality of elastic bulge can follow stretching into, the direction of stretching out of the body of rod evenly setting with the notch, also can set up round or multiturn along the circumference of the body of rod, and specific setting mode is not unique, as long as can ensure that connecting piece 11 is connected with connecting pin 6 is stable, can dismantle simultaneously.

With continued reference to fig. 3, 5 and 7, the handle 10 in this embodiment is in a circular shape, such as a circular truncated cone shape. In order to facilitate the application of force, the handle 10 in this embodiment is an annular cylinder, the outer peripheral surface of which gradually retracts along the extending direction of the connecting piece 11 relative to the connecting pin 6 to form an inclined surface, and the inclined surface is provided with patterns for friction force of the shelf.

Further, a first step is arranged at the through hole in the center of the handle 10 and is used for being clamped with the connecting cap of the connecting piece 11, namely, the connecting piece 11 is clamped with the first step in the through hole of the handle 10 after passing through the through hole of the handle 10, the rod body of the connecting piece 11 passes through the through hole and is matched and connected with the connecting structure of the connecting pin 6, and at the moment, the handle 10 is pressed above the connecting pin 6 and the fixing piece 1 through the connecting piece 11 and can be abutted with the end part of the fixing piece 1 or the second limiting bulge 9 thereof, such as direct abutting or indirect abutting. For convenience in handling the connecting element 11, if the connecting element 11 is a bolt, the surface of the nut/connecting cap facing away from the fixing space may be flush with the corresponding surface of the handle 10 or may sink into the stepped hole of the first step. If the connecting piece 11 is of a structure that is connected with the connecting pin 6 in a plugging mode through arranging an elastic bulge, the connecting cap of the connecting piece needs to extend out of the handle 10 or the connecting cap is flush with the surface of the handle 10, but an operation part positioned outside the handle 10 is arranged on the connecting cap for a user to operate and plug the connecting piece 11, such as a pull ring arranged on the connecting cap, the pull ring is in a rotatable mode, when the connecting piece is not used, the pull ring is rotated to be abutted with the connecting cap, and when the connecting piece 11 is to be pulled, the pull ring is rotated to be raised for the user to operate and realize the plugging of the connecting piece 11.

In addition, the cross section of the handle 10 covers at least part of the fixing element 1 so that the two can be stably clamped against each other to provide stable supporting force for the connecting pin 6. The outer edge of the handle 10 in this embodiment extends out of the fixing member 1, that is, in the axial direction of the connecting pin 6, the shadow area of the handle 10 covers the fixing member 1 and the connecting pin 6, so that the contact area between the handle 10 and the end of the fixing member 1 or the second limiting protrusion 9 can be enlarged, and better supporting force and limiting force can be provided for the connecting pin 6.

In order to further realize the limiting connection pin 6, as shown in fig. 3 and 7, the limiting connection pin is prevented from sliding out of the fixing piece 1 along the axial direction, and is separated from the first to-be-installed piece 2 and the second to-be-installed piece 3, so that the connection of the two to-be-installed pieces is not stable enough, the second connection assembly in the embodiment further comprises a stop piece 12, the stop piece 12 is arranged at one end, away from the first to-be-installed piece 2 and the second to-be-installed piece 3, of the connection pin 6, that is, one end for connecting the second connection assembly, and is positioned on the outer part of the accommodating cavity 4, and the stop piece 12 is simultaneously positioned below the handle 10 and is propped against the end part of the fixing piece 1 or the second limiting protrusion 9 arranged on the fixing piece 1. That is, the handle 10 in this embodiment is abutted against the end of the fixing element 1 or the second limit protrusion 9 by the stop member 12.

For example, as shown in fig. 7, a circle of clamping groove is provided at the position of the second limiting protrusion 9 on the accommodating chamber 4/the fixing element 1, which is outside the second end of the connecting pin 6 in the present embodiment, and the stop member 12 is limited in the clamping groove and abuts against the outer wall of the second limiting protrusion 9. Through the interaction of the stop piece 12 with the clamping groove and the second limiting bulge 9, the connecting pin 6 can not slip out of the fixing piece 1 due to gravity, pressing force or the like, and meanwhile, the connecting pin 6 can not slip out of the fixing piece 1 due to drawing force or the like under the action of the elastic piece 7, so that the connecting pin 6 can have limiting force in the axial direction through the stop piece 12, the clamping groove, the second limiting bulge 9, the first limiting bulge 8 and the limiting of the elastic piece 7, and the connecting pin 6 can be ensured to be stressed in the axial direction, so that the connecting pin 6 can not be separated from the fixing piece 1. Because the first to-be-installed part 2 is matched and connected with the fixing part 1, the connecting pin 6 is connected with the second to-be-installed part 3, therefore, based on the limiting effect of the connecting pin 6, the first connecting component where the connecting pin 6 is located can be matched with the fixing part 1 only so as to stably connect the first to-be-installed part 2 with the second to-be-installed part 3 and prevent the first to-be-installed part and the second to-be-installed part from being separated.

Alternatively, the above-mentioned clamping groove may be formed by partially concave connecting pin 6, or may be formed by sleeving and fixing an annular flange on connecting pin 6, which is not the only specific forming mode.

As shown in fig. 4, the connecting pin 6 in this embodiment includes a first cylinder and a second cylinder, the second cylinder is located at a side of the first cylinder facing the second end of the connecting pin 6, and the cross-sectional dimension of the second cylinder is smaller than that of the first cylinder, that is, the first cylinder and the second cylinder are different in size, and a step is formed at the connection portion between the first cylinder and the second cylinder. The first column body is provided with a circle of annular flange, a groove for connecting the stop piece 12 is formed between the annular flange and the step in a matching way, the first end of the second column body, which faces the connecting pin 6, is provided with an annular protruding edge, and the annular protruding edge is used for forming the first limit protrusion 8. The annular flange may be integrally formed with the connecting pin 6, or may be independently disposed on the connecting pin 6. The stop piece 12 can be an annular gasket or a C-shaped gasket, and is clamped in the groove, and two side surfaces of the stop piece are respectively abutted against the groove surface of the groove and the second limit protrusion 9 on the fixing piece 1. That is, the thickness of the annular or C-shaped spacer in the present embodiment matches the height of the groove, but the width of the spacer is wider than the width of the groove, i.e., the spacer protrudes out of the groove and abuts against the second limit projection 9 of the fixing member 1, so that the stopper 12 applies a force in the antigravity direction to the connecting pin 6 for preventing the connecting pin 6 from sliding out of the fixing member 1 in a direction approaching the first member to be mounted 2.

With continued reference to fig. 3 and 5, the handle 10 in this embodiment covers a ring of annular flanges on the first post, i.e., the annular flanges are located in the through holes of the handle 10, and the lower surface of the handle 10 abuts against the stopper 12. In order to match with the annular flange, a second step is arranged in the through hole of the handle 10, the second step is opposite to the first step in the opening direction, and the annular flange is matched and clamped at the second step. In order to reduce the distance between the handle 10 and the fixing element 1, and better limit the stop element 12, especially when the stop element 12 is a C-shaped element, the stop element 12 is prevented from sliding out of the groove on the connecting pin 6, that is, is separated from the connecting pin 6, and cannot play the role of limiting the connecting pin 6 with the handle 10, in this embodiment, one end of the handle 10 facing the stop element 12 is further provided with a third step, which is communicated with the second step, that is, one end of the handle 10 facing the stop element 12 is provided with a second step hole, or one end of the handle 10 facing the stop element 12 is provided with a limiting groove communicated with the step hole of the second step, and the stop element 12 is located in the step hole of the third step or in the limiting groove and is matched with the step surface of the third step or the groove bottom of the limiting groove to be abutted. In practical application, the depth of the third step or the depth of the limiting groove may be smaller than the thickness of the stop member 12, or may be approximately equal to the thickness of the stop member 12, which is not particularly unique, so long as the effect of surrounding and limiting the stop member 12 can be achieved.

Further, as shown in fig. 7, the connecting pin 6 in this embodiment extends into the handle 10, and the parts of the first step and the second step are correspondingly abutted against the hole wall of the through hole of the handle 10. In order to avoid the instability caused by the rotation of the handle 10 relative to the connecting pin 6, at least the portion of the connecting pin 6 that corresponds to the handle 10 may be rectangular, that is, the first column of the connecting pin 6 may be rectangular, or a non-circular structure such as a polygonal cross section may be provided, or the connecting pin 6 may be entirely a non-circular structure such as a rectangular cross section, a polygonal cross section, or an elliptical cross section. Still alternatively, as in the present embodiment, the connecting pin 6 may be integrally formed as a cylinder with a circular cross section, and only a plane is cut from the portion of the connecting pin 6 corresponding to the handle 10, and a plane body structure corresponding to the plane is also disposed on the corresponding portion of the handle 10, so that the situation of preventing the handle 10 and the connecting pin 6 from rotating relatively can be also realized, and the connection stability of the whole latch module is increased.

The electronic equipment in this embodiment can be notebook computer, desktop computer etc. and the bolt module can be used for fixing the mainboard in the electronic equipment, makes the mainboard stably firmly install on electronic equipment's box, and installs, dismantles conveniently, and required installation space is less, not only is convenient for later stage electronic equipment or the repair maintenance of mainboard, supports electronic equipment miniaturization, slim design moreover, satisfies user's different user demand, if convenient to carry etc. simultaneously more pleasing to the eye, promotes user to electronic equipment's use experience.
