[0033] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0034] like Figure 1 As shown, this embodiment of the invention proposes a hanger structure that is easy to install and dismantle, including an embedded part 1, a locking assembly, and a hanger rod 6; wherein, the embedded part 1 is used to be embedded in the building structure as the positioning and installation foundation of the hanger rod 6; the locking assembly is used to connect the hanger rod 6 and the embedded part 1; the locking assembly includes a locking bracket 2, a locking sleeve 3, and a locking pin 4; the locking bracket 2 is detachably connected to the embedded part 1; the locking sleeve 3 is nested with the locking bracket 2 and slidably connected; the locking pin 4 is movably connected to the sliding sleeve; the hanger rod 6 is detachably connected to the locking sleeve 3; the locking sleeve 3 can move relative to the locking bracket 2 to switch to a first position, a second position, and a third position; in the first position, the locking pin 4 automatically engages and locks with the locking bracket 2; in the second position, the locking pin 4 is unlocked from the locking bracket 2; in the third position, the locking sleeve 3 disengages from the locking bracket 2.

[0035] In this embodiment, during installation, the locking bracket 2 is first installed on the embedded part 1, and then the locking sleeve 3 is moved towards the embedded part 1 to the first position, so that the locking pin 4 automatically locks with the locking bracket 2 to form a reliable connection. Finally, the hanger 6 is installed on the locking sleeve 3. This simple and quick method realizes the connection and assembly of the embedded part 1 and the hanger 6. Compared with the existing technology, which uses drilling to install the hanger 6, this method simplifies the installation process of the hanger 6, reduces the difficulty of operation for workers, and effectively improves the installation efficiency.

[0036] In this embodiment, when the hanger needs to be rearranged, the hanger rod 6 and the locking assembly need to be removed. During removal, the hanger rod 6 is removed first, and then the locking sleeve 3 is pushed towards the embedded part 1 to the second position, which can unlock the locking pin 4 from the locking bracket 2. Then, the locking sleeve 3 is pushed away from the embedded part 1 to the third position, which can disengage the locking sleeve 3 from the locking bracket 2. Finally, the locking bracket 2 can be removed. This simple and quick removal of the locking sleeve 3 and the locking bracket 2 leaves space for the hanger to be rearranged later, which is beneficial for adjusting and modifying the pipeline.

[0037] Furthermore, in this embodiment, the aforementioned embedded part 1 includes a positioning seat 11 and a connecting rod 13. One end of the positioning seat 11 is provided with a connecting ring 12; the other end is connected to the connecting rod 13; the other end of the connecting rod 13 is provided with a threaded structure. During the construction of building structures such as floor slabs, the positioning seat 11 can be fixed to the structural steel bars through the connecting ring 12, and is fixed in the set position of the building structure as the concrete is poured; the position of the positioning seat 11 corresponds to the position of the hanger 6 to be installed, so as to ensure the accurate position of the hanger 6; the connecting rod 13 extends to the bottom of the building structure and is threadedly connected to the locking bracket 2. The connection method is simple to operate and has high stability.

[0038] In one specific embodiment, the positioning seat 11 includes a wing plate and a positioning element. The wing plate is located at one end of the positioning element, and the connecting rod 13 is located at the other end of the positioning element. The external dimensions of the three decrease in sequence. The connecting ring 12 is located on the wing plate, which makes it easier to connect the wing plate to the structural steel bars. After the building structure is finalized, the connection area with the wing plate is large, which can bear the weight of larger conduits or cable trays.

[0039] In one specific embodiment, the positioning base 11 includes a positioning disk and a positioning rod. The positioning disk is provided with a connecting ring 12. One end of the positioning rod is vertically connected to the center of one side of the positioning disk, and the other end is connected to the connecting rod 13.

[0040] Furthermore, in this embodiment, the locking bracket 2 includes an upper ball bracket 21 and a lower ball bracket 22; the diameter of the upper ball bracket 21 is larger than that of the lower ball bracket 22 and the connection end of the positioning seat 11 and the connecting rod 13, and is slidably connected to the connecting rod 13; the center of the lower ball bracket 22 is collinear with that of the upper ball bracket 21, and is threadedly connected to the connecting rod 13; the upper ball bracket 21 has a snap-fit ​​surface and a first guide spherical surface connected to the snap-fit ​​surface, and the lower ball bracket 22 has a bearing surface opposite to the snap-fit ​​surface and a second guide spherical surface connected to the bearing surface.

[0041] In the above embodiment, both the upper ball support 21 and the lower ball support 22 are hemispherical structures and are arranged opposite to each other when installed on the connecting rod 13. The upper ball support 21 is located above the lower ball support 22. In its natural state, the upper ball support 21 falls on the lower ball support 22 under the action of gravity, and its snap-fit ​​surface abuts against the bearing surface of the lower ball support 22.

[0042] The diameter of the upper ball support 21 is larger than that of the lower ball support 22. When the upper ball support 21 falls on the lower ball support 22, the edge of the locking surface of the upper ball support 21 protrudes radially from the bearing surface of the lower ball support 22. The locking surface is used to engage with the locking pin 4 to achieve automatic locking. The bearing surface is used to engage with the locking pin 4 to bear the weight transmitted by the locking pin 4 after automatic locking. The positioning seat 11 is also used to engage with the upper ball support 21 to release the lock.

[0043] Both the first and second guide spherical surfaces can be slidably connected to the locking pin 4, so as to realize the automatic locking, unlocking and separation of the locking support 2 and the locking sleeve 3 during the movement of the locking sleeve 3 along the lower ball support 22 or the upper ball support 21. In this embodiment, the processes of automatic locking, unlocking and separation of the locking support 2 and the locking sleeve 3 are as follows:

[0044] like Figure 2As shown, when the locking sleeve 3 moves along the direction from the lower ball support 22 to the upper ball support 21, it contacts the locking pin 4 and is pushed up by the locking pin 4, so that a gap is formed between the upper ball support 21 and the lower ball support 22. At this time, the locking pin 4 can automatically insert into the gap and make full contact with the bearing surface. In this way, the weight of the locking sleeve 3, the hanger 6 and the pipelines and cable trays supported by the hanger 6 are all borne by the bearing surface and further transferred to the embedded part 1 and the main structure through the lower ball support 22.

[0045] As the locking sleeve 3 continues to move towards the upper ball support 21, it lifts the upper ball support 21 until it engages with the positioning seat 11. At this time, the upper ball support 21 pushes the locking pin 4 away from its center to release the locking state until it slides into contact with the first guide ball surface. At this time, the upper ball support 21 falls onto the lower ball support 22.

[0046] As the locking sleeve 3 moves downward along the upper ball support 21, it can slide and connect with the first guide ball surface and the second guide ball surface in sequence until it is completely separated from the lower ball support 22.

[0047] Furthermore, in this embodiment, the lock sleeve 3 includes a main body and a locking part; the main body has an inner cavity 31 with one end open, the diameter of which is adapted to the diameter of the upper ball support 21; the locking part is provided with a lock hole 32, which is radially connected to the inner cavity 31; a self-locking spring 5 is provided in the lock hole 32, and a locking pin 4 is movably inserted through the lock hole 32 and connected to the self-locking spring 5. Through this arrangement, the self-locking spring 5 can cooperate with the upper ball support 21 and the lower ball support 22 successively, driving the locking pin 4 to move radially relative to the inner cavity 31, thereby realizing the automatic locking, unlocking and separation of the lock support 2 and the lock sleeve 3.

[0048] The inner cavity 31 is used to house the lock support 2 inside the lock sleeve 3 during the movement of the lock sleeve 3; it is understood that the inner cavity 31 has sufficient length along the length direction of the connecting rod 13 so that the locking pin 4 can lift the upper ball support 21 to the positioning seat 11 and continue to move upward until the locking pin 4 contacts the first guide ball surface.

[0049] In one specific embodiment, the locking sleeve 3 has a cylindrical structure with an inner cavity 31 in its middle; the main body and the locking part are integrally molded, and the locking part is located at the opening of the inner cavity 31; the lifting rod 6 is connected to the end of the locking sleeve 3 away from the opening of the inner cavity 31, preferably, the lifting rod 6 is threadedly connected to the locking sleeve 3.

[0050] The locking hole 32 penetrates the locking part radially along the inner cavity 31, and is used to limit the movement direction of the locking pin 4, allowing it to move radially closer to or further away from the inner cavity 31; the self-locking spring 5 is used to realize the movement of the locking pin 4, and the position of the locking pin 4 relative to the inner cavity 31 is different when it is in different degrees of compression; specifically, in the unused state, the self-locking spring 5 is in a naturally relaxed or minimally compressed state, at which time the locking pin 4 extends into the inner cavity 31; when the locking sleeve 3 moves along the lower ball support 22, the locking pin 4 slides and connects with the second guide ball surface, and holds Continue to compress the self-locking spring 5; when the locking pin 4 pushes up the upper ball support 21, the locking pin 4 loses the radial constraint from the lower ball support 22, and moves radially into the gap between the upper ball support 21 and the lower ball support 22 under the action of the rebound force of the self-locking spring 5; when the locking sleeve 3 continues to move, the upper ball support 21 pushes against the locking pin 4, and the locking pin 4 compresses the spring and moves away from the gap; when the locking pin 4 slides upward along the first guide surface, the compression deformation of the self-locking spring 5 gradually decreases; when the locking pin 4 slides downward along the first guide surface, the compression deformation of the self-locking spring 5 gradually increases.

[0051] Furthermore, in the embodiments of this application, such as Figure 3 As shown, the locking pin 4 has a pointed structure 31 at one end near the inner cavity 31. The pointed structure 31 has a guide slope on the side facing the opening of the inner cavity 31, and a pressing surface on the side facing away from the opening of the inner cavity 31. By providing the guide slope, the locking sleeve 3 can be unlocked through sliding connection with the upper ball support 21; by providing the pressing surface, the locking sleeve 3 can be stably fixed on the lower ball support 22, ensuring the stability of the connection and the reliable transmission of load.

[0052] Specifically, when the upper ball support 21 engages with the positioning seat 11 and the locking sleeve 3 continues to move upward, the guide slope can slide with the edge of the upper ball support 21, thereby causing the locking pin 4 to move outward and upward relative to the upper ball support 21 at the same time, until the locking pin 4 slides with the second guide spherical surface, so as to realize that the pressing surface can;

[0053] Specifically, when the locking pin 4 is inserted into the gap between the upper ball support 21 and the lower ball support 22, that is, when it is self-locking, the pressing surface can form a surface contact with the bearing surface, realizing a reliable connection between the two, and thus realizing the effective transfer of load.

[0054] Furthermore, in this embodiment, the end of the locking pin 4 furthest from the pointed structure 31 is provided with a locking head 43. The locking head 43 is located outside the lock hole 32 and movably abuts against the lock hole 32. The locking head 43 is used to limit the maximum length of the locking pin 4 extending into the inner cavity 31, so as to prevent the self-locking spring 5 from driving the locking pin 4 to move and disengage from the lock hole 32 when it rebounds. This ensures that the locking pin 4 can both make contact with the lower ball support 22 and be stably connected with the lock sleeve 3 to achieve load transfer, and play the role of unlocking and separating the lock sleeve 3 from the lock support 2 in subsequent use.

[0055] Specifically, when the card head 43 abuts against the lock hole 32, the pointed structure 31 extends into the inner cavity 31 by a certain length, and the device is in a locked state; when the lock is released and the lock sleeve 3 separates from the lock support 2, the length of the pointed structure 31 extending into the inner cavity 31 is less than the length in the locked state.

[0056] Furthermore, in this embodiment, the length of the locking pin 4 is greater than that of the lock hole 32; along the length direction of the locking pin 4, the length of the pointed structure 31 is greater than the length of the upper ball support 21 that radially protrudes from the lower ball support 22. This arrangement ensures that, in the locked state, the guide slope of the pointed structure 31 is in contact with the edge of the upper ball support 21, so that when the locking sleeve 3 continues to move upward, the two form a sliding connection, thereby releasing the locked state.

[0057] Further, in this embodiment, the lock hole 32 includes a first limiting hole 321 and a second limiting hole 322; the pointed structure 31 is movably engaged with the first limiting hole 321; the self-locking spring 5 is sleeved on the locking pin 4, with its two ends abutting against the pointed structure 31 and the second limiting hole 322 respectively. The first limiting hole 321 is used to limit the extreme position of the locking pin 4 when it moves away from the inner cavity 31, so as to prevent the locking pin 4 from disengaging from the lock hole 32; the second limiting hole 322 is used to cooperate with the locking pin 4 to limit the deformation and movement range of the self-locking spring 5, so that while the lock sleeve 3 moves, the self-locking spring 5 is compressed by the locking pin 4, and the elastic force of the self-locking spring 5 is used to achieve automatic locking, unlocking, and separation of the lock sleeve 3 from the lock support 2.

[0058] In one alternative technical solution, the locking pin 4 includes a pointed structure 31 and a straight section 42 connecting the pointed structure 31 and the locking head 43. The external dimensions of the pointed structure 31 and the locking head 43 are both larger than those of the straight section 42. The self-locking spring 5 is sleeved on the straight section 42, and its two ends abut against the pointed structure 31 and the second limiting hole 322, respectively.

[0059] Preferably, the cross-sectional shape of the locking pin 4 is circular, and the locking head 43 is also circular; the cross-sectional shape of the locking hole 32 is circular.

[0060] In the above embodiment, the locking hole 32 includes a first limiting hole 321, a second limiting hole 322, and a third limiting hole 323 connected in sequence. The first limiting hole 321 is adapted to the pointed structure 31, and its length is not less than the length of the pointed structure 31, and its diameter is slightly larger than the maximum diameter of the cross-section of the pointed structure 31. The second limiting hole 322 is adapted to the self-locking spring 5, and its diameter is smaller than that of the first limiting hole 321, so that the pointed structure 31 can only move within the range of the first limiting hole 321. At the same time, its diameter is larger than the outer dimensions of the self-locking spring 5, allowing the self-locking spring 5 to undergo compression deformation. The third limiting hole 323 is adapted to the straight section 42, and its diameter is smaller than that of the second limiting hole 322, so that the self-locking spring 5 can only move and deform within the range of the second limiting hole 322. At the same time, the diameter of the third limiting hole 323 is smaller than the outer dimensions of the locking head 43, so as to limit the locking head 43 to the outside of the third limiting hole 323.

[0061] In this embodiment, the locking part is uniformly arranged around the circumference of the main body and can be multiple independent structures spaced apart. For example, the locking part can be a boss structure, protruding from the outside of the main body. Each boss is provided with a lock hole 32. Multiple bosses are evenly distributed around the circumference of the main body to ensure that the lock sleeve 3 is subjected to balanced force when locked and to improve the connection stability between the lock sleeve 3 and the lower ball support 22. Preferably, when the locking part is a boss, its number is not less than three. Alternatively, the locking part can also be a ring-shaped structure, protruding from the outside of the main body and having multiple lock holes 32 evenly arranged around the circumference. Preferably, the number of lock holes 32 is not less than three.

[0062] This application also proposes a method for using the above-mentioned easy-to-install and dismantle hanger structure, including an installation method and a dismantling method. The installation method includes:

[0063] S101. During the construction of the building structure, the embedded parts 1 shall be installed simultaneously.

[0064] In this embodiment, the installation of the embedded part 1 is carried out after the steel reinforcement of the building structure is tied. It is fixed to the structural steel reinforcement by the connecting ring 12, corresponding to the position of the hanger 6 to be installed. The embedded part 1 is fixed inside the building structure as the building structure is poured.

[0065] S102. Install the upper ball support 21 and the lower ball support 22 onto the embedded part 1 in sequence;

[0066] In this embodiment, the upper ball support 21 is first passed through the connecting rod 13, and then the lower ball support 22 is threaded to the end of the connecting rod 13 to ensure a stable connection between the lower ball support 22 and the connecting rod 13.

[0067] In this embodiment, a threaded hole is provided in the middle of the bearing surface of the lower ball support 22. During installation, the lower ball support 22 is screwed until the connecting rod 13 reaches the bottom of the threaded hole.

[0068] S103. Install the locking sleeve 3 on the outside of the lower ball support 22, and move the locking sleeve 3 from bottom to top until the locking pin 4 abuts against the lower ball support 22.

[0069] In this embodiment, the locking sleeve 3 is moved from bottom to top, and the locking pin 4 is slidably connected to the second guide spherical surface, so that the locking sleeve 3 can move upward along the lower ball support 22. When the locking pin 4 moves to the top of the second guide spherical surface, the upper end of the locking pin 4 contacts the snap-fit ​​surface of the upper ball support 21. At this time, the locking support 2 continues to move upward, and the upper ball support 21 can be lifted by the locking pin 4, so that a gap is formed between the upper ball support 21 and the lower ball support 22. Under the elastic force of the self-locking spring 5, the locking pin 4 automatically inserts into the gap and fully contacts the bearing surface to achieve automatic locking.

[0070] S104. Install the hanger rod 6 onto the lock sleeve 3;

[0071] In this embodiment, the hanger rod 6 is threaded to the bottom of the locking sleeve 3. After the hanger rod 6 is installed, the C-shaped channel steel 7 can be further installed. The C-shaped channel steel 7 is used to support the conduit and cable tray. The two ends of the C-shaped channel steel 7 are respectively connected to the two hanger rods 6.

[0072] In one specific embodiment, the C-shaped channel steel 7 is provided with mounting holes, the hanger 6 passes through the mounting holes and is locked and fixed by the nut 8.

[0073] Disassembly methods include:

[0074] S201, Remove lifting rod 6;

[0075] If the C-shaped channel steel 7 is connected to the hanger 6, or if there are conduits, cable trays, etc. on the C-shaped channel steel 7, the C-shaped channel steel 7, conduits, cable trays, etc. need to be removed before the hanger 6 is removed, or the conduits and cable trays need to be fixed by other temporary facilities.

[0076] S202. Continue to move the locking sleeve 3 upwards until the locking sleeve 3 passes the upper ball support 21, and the upper ball support 21 slides down onto the lower ball support 22.

[0077] like Figure 4 As shown, continue to move the locking sleeve 3 upwards, so that the locking pin 4 pushes up the upper ball support 21 until the upper ball support 21 engages with the positioning seat 11. At this time, the edge of the upper ball support 21 contacts the guide slope of the locking pin 4. Continue to move the locking sleeve 3 so that the two can slide together. During this process, the upper ball support 21 pushes the locking pin 4 to move away from its center until the pointed structure 31 of the locking pin 4 moves into the first limiting hole 321, and the locking sleeve 3 and the locking support 2 are unlocked.

[0078] Continue moving the locking sleeve 3 upwards, the locking pin 4 slides and connects with the first guide ball surface until the locking sleeve 3 passes the upper ball support 21. At this time, the upper ball support 21 also enters the inner cavity 31 and slides down onto the lower ball support 22.

[0079] S203. Move the lock sleeve 3 downwards until the lock sleeve 3 disengages from the lock support 2;

[0080] When moving the locking sleeve 3 downwards, as Figure 5 As shown, the locking pin 4 is slidably connected to the first guide ball surface until it moves to the bottom of the upper ball support 21; when it continues to move downward, the locking pin 4 is slidably connected to the second guide ball surface until the locking pin 4 moves to the bottom of the lower ball support 22, at which point the locking sleeve 3 separates from the locking support 2.

[0081] S204, Remove lock bracket 2;

[0082] First, remove the lower ball support 22 from the connecting rod 13, then remove the upper ball support 21. The locking support 2 and locking sleeve 3 can be reused in the next location, which can effectively save construction costs.

[0083] The advantages and positive effects of this invention are:

[0084] (1) By setting a locking bracket consisting of an upper ball support and a lower ball support, as well as a locking sleeve with an inner cavity and a locking pin movably set on the locking sleeve, the locking pin and the locking bracket can be automatically locked in the first position during the movement of the locking sleeve relative to the locking bracket, so that the locking sleeve and the lower ball support can form a reliable connection, and the installation of the lifting rod can be completed easily and quickly. Compared with the existing technology of installing the lifting rod by drilling holes, the installation process of the lifting rod is simplified, the difficulty of operation for workers is reduced, and the installation efficiency is effectively improved. At the same time, the connection is stable, ensuring the reliable transmission of load. The locking pin and the locking bracket can also be unlocked in the second position by moving the locking sleeve, and the locking sleeve can be disengaged from the locking bracket in the third position, so that the removal of the locking sleeve and the locking bracket can be achieved more easily and quickly.

[0085] (2) The operation is simple and easy to control. The lock sleeve and lock bracket can be reused, which helps to save construction costs.
