[0004] The present invention relates to the technical field of threaded installation, and in particular to a directionable threaded installation structure and an installation method thereof. Background Art

[0005] Currently commonly used threaded installation structures do not have a directional function due to the random distribution of the starting and ending positions of the threads. For example, with a cross-slot screw, there is no way to ensure that the cross slot is always in a vertical or horizontal state after installation. In addition, the commonly used directional structure uses a stop for orientation, and then the threads need to be locked from the inside of the device. When the threaded structure is disassembled, the device needs to be disassembled.

DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0060] The terms "first," "second," etc., used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of such features. In the description of this disclosure, unless otherwise specified, "plurality" means two or more.

[0061] In the present invention, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0062] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0063] Example 1:

[0064] In the prior art, commonly used threaded installation structures such as cross-slot screws and threaded bolts, etc., have random distribution of the starting and ending positions of the threads, so it is impossible to ensure that the cross slot is always in a vertical or horizontal state after installation. This may make it difficult to control the direction during installation or disassembly, and it is necessary to adjust according to actual conditions; at the same time, for threaded connections using directional structures, it may be necessary to tighten the threads from the inside of the device during disassembly, which means that when performing disassembly operations, the device may need to be disassembled before it can be carried out, which increases the complexity and workload of disassembly.

[0065] In order to solve the problems existing in the prior art, embodiment 1 of the present invention provides a directional threaded installation structure, as shown in Figure 1, comprising: a fixed component 1 and a movable part 2, wherein the fixed component 1 is provided on the device, and the movable part 2 is installed on the fixed component 1; wherein, the fixed component 1 can be fixed inside the device, and under some specific requirements, the fixed component 1 can also be fixed outside the device, and the specific situation depends on the actual situation. The movable part 2 can be selected according to actual use requirements. The movable part 2 matches the fixed component 1, and the installation and disassembly of the movable part 2 can be completed from the outside of the device. Moreover, after the installation of the movable part 2 is completed, except for the part installed into the fixed component 1, the rest of the movable part 2 is outside the device, which is convenient for using the movable part 2 from the outside. The movable part 2 can be an L-shaped screw, and the external L-shaped bend can be used to hold items. Its specific structure will be described below.

[0066] In a preferred embodiment, referring to Figure 2, the fixing assembly 1 includes a fixing base 10, a nut 11 and an elastomer 12, and the nut 11 and the elastomer 12 are arranged in the fixing base 10; a bayonet 100 is provided at one end of the fixing base 10, and a boss 20 is provided on the movable part 2, and the bayonet 100 matches the boss 20 for controlling the installation direction of the movable part 2.

[0067] The fixing base 10 is fixed inside the device. This fixing includes but is not limited to using an adhesive to fix the bottom of the fixing base 10 inside the device, and fixing the bottom of the fixing base 10 inside the device with screws. The nut 11 and the elastic body 12 are disposed inside the fixing base 10. The elastic body 12 may be a spring. In other embodiments, the elastic body 12 may be replaced with other elastic devices. This is not described further in this embodiment.

[0068] A bayonet 100 is provided at one end of the fixing seat 10, and a boss 20 is provided on the movable part 2, and the bayonet 100 matches the boss 20. The shape of the bayonet 100 can be consistent with the shape of the boss 20, and the volume of the boss 20 is slightly smaller than the volume of the bayonet 100, so that the boss 20 can enter the bayonet 100. The depth of the bayonet 100 is the height of the boss 20. The shape and size of the bayonet 100 and the boss 20 can be set according to actual needs and are not specifically limited in this embodiment. When the movable part 2 is installed on the fixed component 1, the bayonet 100 will be correctly aligned with the boss 20, and the installation direction of the movable part 2 can be controlled by setting the direction of the bayonet 100.

[0069] The installation method of the nut 11 , the elastic body 12 and the fixing seat 10 will be described below.

[0070] In a preferred embodiment, the movable part 2 is used to be connected to the nut 11, and the movable part 2 is continuously rotated in a preset locking direction to allow the nut 11 to slide in the fixing seat 10 until the boss 20 is engaged with the bayonet 100; when the boss 20 completely enters the bayonet 100, the elastomer 12 is used to reset the nut 11, and the nut 11 is used to pull the movable part 2 to achieve locking of the movable part 2.

[0071] As shown in Figure 3, when the nut 11, elastic body 12, and fixing seat 10 are pre-assembled, the elastic body 12 is in a compressed state, exerting a backward preload on the nut 11, so that the nut 11 is normally located at the rear end of the fixing seat 10. The preset tightening direction depends on the thread distribution within the nut 11 and can be clockwise or counterclockwise. In this embodiment, the clockwise direction is used as an example. By locking the movable part 2, the boss 20 on the movable part 2 continuously approaches the bayonet 100 until the boss 20 contacts the front surface of the fixing seat 10. At this time, the movable part 2 is continued to be rotated, and the movable part 2 will drive the nut 11 to move toward the front surface of the fixing seat 10 in the fixing seat 10, and the nut 11 will compress the elastic body 12. When the boss 20 enters the bayonet 100, the nut 11 will move backward under the action of the elastic body 12, and at the same time drive the movable part 2 to be locked until the boss 20 completely enters the bayonet 100. At this time, the movable part 2 cannot be rotated any further, and the locking of the threaded mounting structure is completed.

[0072] Compared with the prior art, the beneficial effects of the present invention are: on the one hand, the present invention installs the fixing component on the device and the movable part on the fixing component, and the movable part is outside the device after installation, so that the installation and disassembly of the threaded mounting structure can be completed outside the device without disassembling the device; on the other hand, by setting the bayonet to match the boss, the installation direction of the movable part can be controlled by setting the direction of the bayonet, and the movable part can be stabilized in the required direction.

[0073] The specific structure of the threaded mounting structure will be described below.

[0074] In a preferred embodiment, as shown in FIG4 , the movable portion 2 includes a screw 21 , the screw 21 is provided with a first thread 22 , and the boss 20 is provided at the tail of the screw 21 ; the screw 21 is mounted on the nut 11 through the first thread 22 .

[0075] In this embodiment, the movable part 2 can be an L-shaped movable part, and a screw rod 21 is provided at the front end of the movable part 2. The first thread 22 on the screw rod 21 matches the thread in the nut 11. The length of the first thread 22 can include the entire screw rod 21, or only a section of the first thread 22 is provided at the front part of the screw rod 21, and this section of the first thread 22 matches the thread on the nut 11.

[0076] The length of the screw 21 is set according to the length of the fixing seat 10 and actual needs. The boss 20 is set at the tail of the screw 21. The bending part of the movable part 2 can be set according to actual needs. It can be used as a direction indicator of the screw 21 and can also be used for other external uses.

[0077] In order to set the nut 11 in the fixing seat 10 and facilitate the sliding of the nut 11, in a preferred embodiment, as shown in Figure 5, the fixing seat 10 also includes a sliding groove 101 and a through hole 102, and the sliding groove 101 is connected to the through hole 102; the nut 11 is slidably set on the sliding groove 101, and the inner surface of the through hole 102, the inner surface of the sliding groove 101 and the outer surface of the nut 11 are matched to facilitate the nut 11 to slide in the sliding groove 101 and the through hole 102; as shown in Figure 6, the nut 11 is provided with a second thread 110, and the second thread 110 matches the first thread 22, and the screw 21 is connected to the nut 11 through the through hole 102.

[0078] In a preferred embodiment, in order to facilitate the sliding of the nut 11 in the sliding groove 101, corresponding sliding components can be provided on the sliding groove 101 and the nut 11. For example, a sliding bar can be provided in the sliding groove 101, and a notch matching the sliding bar can be provided on the outer surface of the nut 11. Alternatively, a notch can be provided in the sliding groove 101, and a sliding bar matching the notch can be provided on the outer surface of the nut 11. The specific implementation method will not be described in detail in this embodiment.

[0079] In other embodiments, the bottom of the sliding groove 101 can be a plane. In order to reduce the friction of the nut 11 sliding in the sliding groove 101, the bottom of the sliding groove 101 can also be set to be hollow and used in conjunction with the above-mentioned sliding component. The specific implementation method will not be described in detail in this embodiment.

[0080] The nut 11 can be set to be square and the sliding groove 101 is a plane. In other embodiments, only one surface of the nut 11 can be ensured to be a plane to prevent the nut 11 from flipping over, and this plane can be used as the contact surface between the nut 11 and the sliding groove 101. The other surfaces can be of any shape; the sliding groove 101 is used for the sliding of the nut 11. Referring to Figures 5 and 7, a limit platform 103 is provided at one end of the sliding groove 101, and one end of the nut 11 abuts against the limit platform 103 to limit the sliding range of the nut 11.

[0081] 3 , 5 and 6 , a limit block 104 is provided between the sliding groove 101 bayonet 100 and the through hole 102, and the elastomer 12 is arranged in the sliding groove 101 through hole 102; a protrusion 111 is provided at the other end of the nut 11, one end of the elastomer 12 abuts against the limit block 104, and the other end of the elastomer 12 is connected to the nut 11, and the protrusion 111 is used to prevent the elastomer 12 from sliding out.

[0082] In the initial state, the elastic body 12 is arranged in the sliding groove 101, one end of the elastic body 12 abuts against the limit block 104, and the other end of the elastic body 12 abuts against the nut 11. The nut 11 is provided with a protrusion 111 to prevent the elastic body 12 from sliding. For example, the protrusions 111 can be provided at the four corners of the nut 11 to limit the four sides of the elastic body 12. When the elastic body 12 is in a compressed state, there is a backward pre-pressure on the nut 11, and the limit platform 103 is used to balance the pre-pressure applied by the elastic body 12 to the nut 11. In other embodiments, the limit platform 103 can also be set to a closed state, and the nut 11 can be blocked by a square block structure to balance the pre-pressure applied by the elastic body 12 to the nut 11. However, the implementation of this solution requires an opening in the square block structure for the passage of the tail of the screw 21. The specific implementation scheme is not further explained in this embodiment.

[0083] In order to facilitate setting the locking and unlocking force of the threaded mounting structure according to actual needs, in a preferred embodiment, as shown in Figures 8-10, the boss 20 includes a first limiting surface 200 and a second limiting surface 201, and the first limiting surface 200 and the second limiting surface 201 are inclined surfaces or straight surfaces, and the shape of the bayonet 100 matches the first limiting surface 200 and the second limiting surface 201.

[0084] Among them, after the boss 20 contacts the front surface of the fixed seat 10 as the movable part 2 rotates, in order to facilitate the rotation of the movable part 2, the two surfaces of the boss 20 are set to be inclined surfaces or straight surfaces, which is more conducive to the rotation of the movable part 2. In actual use, there may be different requirements for locking and unlocking forces. Therefore, according to the actual locking force and unlocking force, the first limiting surface 200 and the second limiting surface 201 are set as follows: the first limiting surface 200 and the second limiting surface 201 are inclined surfaces or straight surfaces, including: the first limiting surface 200 and the second limiting surface 201 are both inclined surfaces; or, the first limiting surface 200 and the second limiting surface 201 are both straight surfaces; or, the first limiting surface 200 is an inclined surface and the second limiting surface 201 is a straight surface; or, the first limiting surface 200 is a straight surface and the second limiting surface 201 is an inclined surface.

[0085] It is worth noting that regardless of whether the first limiting surface 200 and the second limiting surface 201 are straight or inclined, the contact surfaces of the bayonet 100 that mate with the first limiting surface 200 and the second limiting surface 201 are compatible. In this embodiment, there are two bosses 20, arranged symmetrically above and below the center. Therefore, the bayonet 100 also has two portions for retaining the bosses 20. In other embodiments, multiple bosses 20 may be provided to ensure that the first limiting surface 200 and the second limiting surface 201 on the bosses 20 are oriented in the same direction, thereby reducing effort when locking or unlocking the movable portion 2. This will not be further explained in this embodiment.

[0086] As shown in FIG8 , the movable portion 2 and the fixed assembly 1 are locked. When the first limiting surface 200 is a straight surface and the second limiting surface 201 is an inclined surface, assuming that the locking direction is in the clockwise direction, the locking torque of the device is less than the unlocking torque. When unlocking, the movable portion 2 must first be pulled outward along the axial direction of the movable portion 2 until the boss 20 disengages from the latch 100 on the fixed seat 10, and then the movable portion 2 is unlocked. When the first limiting surface 200 is an inclined surface and the second limiting surface 201 is a straight surface (not shown in the figure), assuming that the locking direction is in the clockwise direction, the locking torque of the device is greater than the unlocking torque. When locking, when a portion of the boss 20 enters the latch 100, the movable portion 2 must first be pulled outward along the axial direction of the movable portion 2 until the boss 20 disengages from the latch 100 on the fixed seat 10, and then the movable portion 2 is locked.

[0087] As shown in Figure 9, when the bevel angle of the first limiting surface 200 is greater than the bevel angle of the second limiting surface 201, the locking torque of the movable part 2 is less than the unlocking torque of the movable part 2; when the bevel angle of the first limiting surface 200 is less than the bevel angle of the second limiting surface 201, the locking torque of the movable part 2 is greater than the unlocking torque of the movable part 2.

[0088] The first limiting surface 200 and the second limiting surface 201 are both inclined surfaces, and their oblique angles will affect the locking torque and unlocking torque of the movable part 2. When the oblique angle of the first limiting surface 200 is greater than the oblique angle of the second limiting surface 201, the locking torque of the movable part 2 is less than the unlocking torque. In this state, a greater force is required to unlock the movable part 2, and the locking effect is also better. When the oblique angle of the first limiting surface 200 is less than the oblique angle of the second limiting surface 201, the locking torque of the movable part 2 is greater than the unlocking torque. In this case, a greater force is required to lock the movable part 2. This design may be used to ensure that the device remains stable in a specific working state, or to provide sufficient force when the device state needs to be changed.

[0089] As shown in Figure 10, the first limiting surface 200 and the second limiting surface 201 are both straight surfaces, including: when the movable part 2 is locked or unlocked, the boss 20 enters the bayonet 100 of the fixed seat 10, and then the movable part 2 is pulled outward along the axial direction of the movable part 2 until the boss 20 is disengaged from the bayonet 100 on the fixed seat 10, and then the movable part 2 is locked or unlocked.

[0090] Among them, when the first limiting surface 200 and the second limiting surface 201 are both straight surfaces, as the movable part 2 rotates, the boss 20 gradually approaches the bayonet 100. When the boss 20 partially enters the bayonet 100, since the second limiting surface 201 is a straight surface, if the movable part 2 is continued to be rotated, the boss 20 will be stuck in the bayonet 100 and cannot continue to rotate. At this time, it is necessary to first pull the movable part 2 outward along the axial direction of the movable part 2, while driving the nut 11 to compress the elastic body 12, and then continue to rotate the movable part 2. When the boss 20 enters the bayonet 100 again, the above operation is repeated until the boss 20 completely enters the bayonet 100, completing the locking of the movable part 2. When unlocking is required, the movable part 2 is pulled along the axial direction of the movable part 2 and rotated in the opposite direction of the locking direction until it is completely unlocked.

[0091] Example 2:

[0092] In Example 1, a directional threaded mounting structure is proposed. In this embodiment, its mounting method will be further described. As shown in Figures 1, 2, and 11, the mounting method includes:

[0093] Step 101 : Connect the movable part 2 to the nut 11 , and continuously rotate the movable part 2 in a preset locking direction to allow the nut 11 to slide in the fixing seat 10 until the boss 20 engages with the bayonet 100 .

[0094] 13 , the screw 21 is screwed into the nut 11 and the screw 21 is screwed into the nut 11. At this time, the angle a between the tail of the screw 21 and the vertical direction is recorded as a0, which is the angle from the tail of the screw 21 to the vertical direction along the tightening direction of the first thread 22, in degrees, and may be any angle.

[0095] Step 102 : When the boss 20 completely enters the bayonet 100 , the elastic body 12 resets the nut 11 , and the nut 11 pulls the movable part 2 to achieve locking of the movable part 2 .

[0096] When the screw 21 continues to be rotated in the tightening direction, since the boss 20 on the screw 21 contacts the front surface of the fixing seat 10, it will be supported by the fixing seat 10, and the screw 21 cannot move axially toward the rear side of the fixing seat 10. As a result, the screw 21 will pull the nut 11, causing the nut 11 to move axially toward the front end of the fixing seat 10 in the sliding groove 101 and the through hole 102.

[0097] Continue to rotate the screw 21 in the tightening direction. The angle a between the tail of the screw 21 and the vertical upward direction gradually decreases. When a decreases to 0, the boss 20 aligns with the bayonet 100 on the fixing seat 10. The nut 11 moves axially forward by a distance L1 = a0 / 360*p, where p is the pitch of the thread. At this point, the screw 21 is no longer in contact with the fixing seat 10. The support force of the fixing seat 10 on the screw 21 disappears. The nut 11 is subjected to the elastic force of the elastic body 12, and the nut 11 drives the screw 21 backward until it contacts the stopper 103. The movement distance is L1, which is also the depth of the boss 20 on the screw 21 entering the bayonet 100.

[0098] In combination with the aforementioned embodiment 1, as shown in FIG14 , different locking methods are selected according to the shapes of the first limiting surface 200 and the second limiting surface 201 on the boss 20 introduced in embodiment 1, which will not be described in detail in this embodiment. If the screw 21 is continued to rotate, so that the boss 20 is separated from the bayonet 100, the boss 20 is in contact with the front surface of the fixing seat 10 again, and the screw 21 drives the nut 11 to move axially toward the front surface of the fixing seat 10, and then rotates to a=0. The distance L2 of the nut 11 moving forward axially is L2=a0 / 360+1*p. At this time, the screw 21 has no contact with the fixing seat 10, and the supporting force of the fixing seat 10 on the screw 21 disappears. The nut 11 is subjected to the elastic force of the elastic body 12, and the nut 11 will drive the screw 21 to move backward until it contacts the limiting platform 103. The movement distance is L2, which is also the depth of the boss 20 entering the bayonet 103. By repeating this process, the following can be obtained:

[0099] When a=0 for the first time, L1=a0 / 360*p;

[0100] The second time a=0, L2=(a0 / 360+1)*p;

[0101] The third time a=0, L3=(a0 / 360+2)*p;

[0102] When a=0 for the Nth time, Ln=(a0 / 360+n-1)*p.

[0103] In combination with the aforementioned embodiment 1, as shown in FIG15 , when Ln is greater than the height of the boss 20 , the boss 20 partially and completely enters the interior of the bayonet 100 , which means that the installation is completed.

[0104] The specific structure of the orientable threaded mounting structure is described in Example 1 and will not be repeated in this embodiment.

[0105] Example 3:

[0106] In Example 1, an orientable threaded mounting structure is proposed. In this embodiment, a use example of the threaded mounting structure is proposed to further illustrate the structure.

[0107] As shown in FIG16 , a chassis product is provided, the front panel of which is designed with two fiber optic brackets for supporting and fixing optical fibers. The tail of the bracket is required to be vertically upward to support and fix the optical fibers or cables. The fiber optic bracket is outside the chassis, which increases the overall size of the chassis, increases packaging and transportation costs, and is not conducive to equipment installation. Through the threaded mounting structure, the fixing component 1 is set inside the chassis, and the fiber optic bracket is designed as a detachable part as the movable part 2. As shown in FIG17 , after the equipment in the chassis and the fixing component 1 are installed, the movable part 2 is installed. The vertical structure at the tail of the movable part 2 can be used to support and fix the optical fiber or cable outside the chassis, thereby reducing packaging and transportation costs.

[0108] Among them, the specific structure of the threaded mounting structure is referred to Example 1, and the installation method of the threaded mounting structure is referred to Example 2, which will not be repeated in this embodiment.
