Description

TECHNICAL FIELD

[0001] The utility model relates to the field of connecting structure, in particular to a kind of hoop structure. BACKGROUND

[0002] Hoop structure, hoop structure is often used to be connected on tubular structure, usually including main body and connecting rod, wherein, main body is used to be arranged on the outer wall surface of tubular structure, and connecting rod is usually connected to first end and second end, and can be cooperated with other structures (such as nut), realize the adjustment of the spacing between the first end and the second end of main body structure, to realize the locking of main body and tubular structure.

[0003] For example, the Chinese patent with publication number CN 117231603A discloses a hoop, a hoop installation device and a hoop installation method, and specifically discloses that the hoop body 10 further includes a quick-mounting assembly 16, which is used to lock the head flange 14 and the tail flange 15 when the hoop body 10 is folded……The quick-mounting assembly 16 includes a tensioning bolt 161, a tensioning nut 162, and a positioning nut 163. First and second communication holes are formed on the head flange 14 and the tail flange 15, respectively. When the hoop body 10 is folded, the tensioning bolt 161 passes through the positioning nut 163, the first communication hole, the second communication hole, and the tensioning nut 162 in sequence to lock the hoop body 10.

[0004] The existing hoop structure and hoop structure usually adopt the structure shown in the above-mentioned scheme to realize the locking and disassembly of the hoop body by cooperating with the bolt and nut, but it is limited by the nut adjustment. The axial movement distance is small when the nut is rotated each time, and the hoop and hoop body cannot be quickly disassembled. SUMMARY

[0005] The technical problem to be solved by the utility model is to overcome the defects in the prior art, thereby providing a hoop structure. To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A hoop structure, comprising:

[0007] The main body has a first end and a second end, and the distance between the first end and the second end can be changed to change the locking strength of the main body and realize the disassembly of the main body;

[0008] The connecting rod is connected to the first end and passes through the second end;

[0009] The hoop structure further comprises:

[0010] The adjusting assembly is slidably arranged on the connecting rod and located on the side of the second end away from the first end, and the adjusting assembly can change its axial length.

[0011] The disassembly assembly is connected with the connecting rod and forms a limiting section with the first end to limit the axial movement space of the second end and the adjusting assembly, and the disassembly assembly has a first state and a second state, and the axial length of the limiting section in the first state is smaller than that in the second state;

[0012] In the first state, the adjusting assembly with different axial lengths will make the first end and the second end have different distances to achieve different locking strength of the clamp structure; in the second state, the main body is in a disassembled state.

[0013] According to the above scheme, the adjusting assembly is slidably installed on the connecting rod and located between the disassembly assembly and the second end of the main body, so that one end of the adjusting assembly can be limited by the disassembly assembly, and the other end can apply a force to the second end of the main body when the axial length of the adjusting assembly changes, thereby pushing the second end to approach or move away from the first end, and adjusting the locking strength of the main body. Further, the disassembly assembly can realize quick installation and disassembly of the clamp, for example, in the first state, the clamp structure is in an installed state, and in the second state, the clamp is in a disassembled state. In the traditional clamp structure, the functions of adjustment and disassembly are realized by the cooperation of the bolt and the nut. In this case, since the bolt needs to function as an adjustment, it is difficult to achieve quick disassembly. The arrangement of the adjusting assembly and the disassembly assembly separates the adjustment function from the disassembly function. Therefore, the adjusting assembly can change the axial length slowly to make the clamp have different locking strengths, and the disassembly assembly can change the axial length quickly to realize quick installation and disassembly of the clamp. Thus, the adjustment function of the adjusting assembly and the disassembly function of the disassembly assembly do not affect each other, so that the adjusting assembly can change the axial length slowly to facilitate fine adjustment, and the disassembly assembly can quickly switch between the first state and the second state without being affected by the change of the axial length of the adjusting assembly.

[0014] It can be understood that when the clamp structure needs to be locked, the disassembly assembly is switched from the second state to the first state, the axial length of the limiting section is relatively reduced, one end of the adjusting assembly close to the disassembly assembly is limited by the disassembly assembly, and the other end can push the first end of the main body to approach or move away from the second end, so as to adjust the distance between the first end and the second end of the main body, and further adjust the locking strength of the main body. When the clamp structure needs to be disassembled, the disassembly assembly is switched from the first state to the second state, at this time, the axial length of the limiting section is relatively increased, the adjusting assembly can slide along the connecting rod away from the second end, the distance between the first end and the second end is quickly increased, and the clamp structure is quickly unlocked.

[0015] Preferably, the disassembling assembly comprises a first rotating member, a guide groove arranged on the first rotating member, and a guide rod matched with the guide groove, the guide rod is inserted into the connecting rod in a plug-in manner;

[0016] The guide groove comprises at least an active section extending in the axial direction and a locking section extending only in the circumferential direction, and the active section is located on one side of the locking section close to the first end.

[0017] Through the above scheme, the guide rod is inserted into the connecting rod in a plug-in manner, and is matched with the guide groove arranged on the first rotating member, so that when the first rotating member rotates, the guide rod can be located at different positions of the guide groove, and the guide groove has at least an active section extending in the axial direction and a locking section extending only in the circumferential direction, when the guide rod moves along the active section, the first rotating member can move axially relative to the connecting rod, thereby realizing quick disassembly of the clamp structure; when the guide rod is located in the locking section, the axial position of the first rotating member relative to the connecting rod is fixed due to the axial limiting of the locking section on the circumferential direction of the guide rod, so that the end of the adjusting assembly close to the disassembling assembly is limited, thereby increasing the locking effect of the clamp structure; when the locking section and the guide rod are matched, even if the locking section and the guide rod axially abut, they will not slide circumferentially due to the abutting force.

[0018] Preferably, the active section is a helical groove structure extending in the axial direction and the circumferential direction.

[0019] Through the above scheme, the active section is set as a helical groove structure, so that during locking of the clamp structure, the rotational movement of the first rotating member is converted into axial movement through the inclined surface, so that the first rotating member only needs to overcome a smaller component force along the inclined surface of the helical groove, and does not need to directly apply a counterforce to the second end of the adjusting assembly and the main body, thereby being able to reduce the driving force required to drive the first rotating member to move to a certain extent, and realizing more labor-saving locking of the clamp structure.

[0020] Preferably, the active section further comprises a first section and a second section, the second section is located between the first section and the locking section, and the lead angle of the first section is greater than the lead angle of the second section.

[0021] Through the above scheme, the active section is set as the first section and the second section with different lead angles, when the guide rod moves in the first section, the first rotating member can move axially quickly, thereby realizing quick disassembly of the clamp structure; when the guide rod moves in the second section, the first rotating member moves axially slowly, and at the same time, the first rotating member rotates more labor-savingly when rotating the same angle, so as to better overcome the resistance during locking of the main body.

[0022] Preferably, the axial length of the first section is greater than the axial length of the second section.

[0023] Through the above scheme, the clamp structure can be quickly disassembled during disassembly.

[0024] Preferably, the lead angle of the guide groove is gradually changed, and the lead angle is larger as it is closer to the first end.

[0025] Through the above scheme, the lead angle of the guide groove is smaller as it is closer to the locking section. When the first rotating member rotates by the same angle during locking of the clamp structure, the change in axial distance gradually decreases, thereby achieving more labor-saving locking of the clamp structure.

[0026] Preferably, the guide groove is provided with two, and the two guide grooves are rotationally symmetrically arranged about the center axis of the connecting rod.

[0027] The guide rod is arranged through the connecting rod and is arranged at both ends in cooperation with the two guide grooves, or the guide rod is provided with two, and the two guide rods are arranged in cooperation with the two guide grooves.

[0028] Through the above scheme, through the cooperation between the multiple guide grooves and the connecting rod, the force on the guide rod is more uniform, avoiding stress concentration on the guide rod during main locking, which causes damage and deformation of the guide groove and the guide rod.

[0029] Preferably, the first rotating member is provided with a driving sleeve outside, and the driving sleeve is fixedly connected with the first rotating member to drive the first rotating member to rotate.

[0030] Through the above scheme, the driving sleeve is fixedly connected with the first rotating member, thereby driving the first rotating member to rotate, so that the rotation adjustment of the first rotating member is more convenient and labor-saving.

[0031] Preferably, the adjustment assembly comprises a rotating sleeve, one of the rotating sleeve and the first rotating member is provided with a circumferentially extending cooperation groove, and the other is provided with a cooperation pin inserted into the cooperation groove, so that when the first rotating member moves axially, the cooperation groove and the cooperation pin cooperate to make the adjustment assembly move axially synchronously.

[0032] Through the above scheme, the rotation adjustment of the disassembling assembly and the adjustment assembly is not affected, and the disassembling assembly can drive the adjustment assembly to move axially synchronously, so that when the disassembling assembly moves axially, the adjustment assembly can be directly driven to move axially away from or close to the second end of the main body, achieving quick unlocking or quick locking of the clamp structure.

[0033] Preferably, the adjusting assembly further comprises a second rotating member, an abutting member, a guide member and a guide surface, the guide surface is a spiral surface structure, the guide member is slidably connected with the guide surface, one of the guide member and the guide surface is arranged on the second rotating member, and the other is arranged on the abutting member, the rotating sleeve is internally provided with an accommodating cavity, the guide member, the guide surface and the second rotating member are located inside the accommodating cavity, and the second rotating member is circumferentially limitedly connected with the rotating sleeve.

[0034] The adjusting assembly further comprises a plurality of grooves arranged on the guide surface, so that when the guide member cooperates with the grooves and slides on the guide surface, the abutting member and the second rotating member will move in a direction away from each other.

[0035] Through the above scheme, the rotating sleeve is arranged to drive the second rotating member, the guide surface is arranged as a spiral surface, so that it is more labor-saving to adjust the locking of the second rotating member and the locking hoop structure, the grooves arranged on the guide surface can not affect the sliding of the guide member along the guide surface to drive the relative movement of the abutting member and the second rotating member, and can also make the second rotating member stop rotating, when the abutting member abuts against the second end of the main body, the guide member can be clamped into the groove, thereby the stability of the abutting member can be increased to a certain extent, and the locking effect of the clamp structure is increased.

[0036] It can be understood that the rotating sleeve can drive the second rotating member to rotate synchronously during the rotation of the rotating sleeve, so that different positions of the guide surface abut against the guide member, thereby driving the abutting member to slide along the axial direction, and the adjustment of the axial length of the adjusting assembly is realized.

[0037] Compared with the prior art, the utility model has at least the following beneficial effects:

[0038] 1、 by the adjustment assembly slip installation connecting rod, and between the disassembly and assembly component and the main body second end, make the adjustment assembly one end can be limited by the disassembly and assembly component, and the other end can apply force to the main body second end when the adjustment assembly changes its axial length, in turn, push the second end close to or away from the first end, realize the adjustment of the main body locking strength. Further, through the disassembly and assembly component and the adjustment assembly cooperate with each other, wherein, the disassembly and assembly component can quickly realize the change of the limiting section axial length, and the adjustment assembly can change its axial length in the limiting section, in turn, can realize the quick installation and disassembly of the clamp structure. It can be understood that when the clamp structure needs to be locked, the disassembly and assembly component is switched from the second state to the first state, the axial length of the limiting section is relatively reduced, and the end of the adjustment assembly close to the disassembly and assembly component is limited by the disassembly and assembly component, and the other end can push the first end of the main body close to or away from the second end, realize the adjustment of the distance between the first end and the second end of the main body, further realize the adjustment of the main body locking strength.

DETAILED DESCRIPTION

[0054] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0055] In the description of the present application, it should be noted that the directions or position relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0056] Referring to Figures 1 to 8 The present application provides a clamp structure, which comprises a main body 1, a connecting rod 2, an adjusting assembly 3 and a dismounting assembly 4. The main body 1 has a first end 11 and a second end 12, and the locking strength of the main body 1 can be changed by changing the distance between the first end 11 and the second end 12, and the main body 1 can be disassembled. The connecting rod 2 is connected to the first end 11 and penetrates through the second end 12. The adjusting assembly 3 is slidably arranged on the connecting rod 2 and located on the side of the second end 12 away from the first end 11, and the adjusting assembly 3 can change its axial length. The dismounting assembly 4 is located on the side of the adjusting assembly 3 away from the second end 12, and the dismounting assembly 4 is connected with the connecting rod 2 and forms a limiting section with the first end 11 to limit the axial movement space of the second end 12 and the adjusting assembly 3. The dismounting assembly 4 has a first state and a second state, and the axial length of the limiting section in the first state is smaller than that in the second state. In the first state, the adjusting assembly 3 with different axial lengths will make the first end 11 and the second end 12 have different distances, so as to realize that the clamp structure has different locking strengths. In the second state, the main body 1 is in a disassembled state.

[0057] It should be understood that the adjusting assembly 3 is slidingly mounted on the connecting rod 2 and located between the disassembling assembly 4 and the second end 12 of the main body 1, so that one end of the adjusting assembly 3 can be limited by the disassembling assembly 4, and the other end can apply a force to the second end 12 of the main body 1 when the adjusting assembly 3 changes its axial length, thereby pushing the second end 12 to approach or move away from the first end 11, achieving the adjustment of the locking strength of the main body 1.

[0058] Further, through the cooperation of the disassembling assembly 4 and the adjusting assembly 3, the disassembling function and the adjusting function of the clamp structure can be separated from each other, so as to avoid the traditional clamp structure which simultaneously realizes the functions of adjustment and disassembly through the cooperation of bolts and nuts, resulting in that it is difficult to realize the function of quick disassembly while meeting the function of adjustment. As for the screw drive mechanism similar to the threaded cooperation, if the thread angle of the screw drive structure is large, the structure is difficult to realize fine adjustment, and if the thread angle is small, it is difficult to realize quick installation and disassembly.

[0059] Therefore, the arrangement of the aforementioned disassembling assembly 4 and the adjusting assembly 3 can realize that the adjusting assembly 3 changes its axial length slowly to make the clamp have different locking strengths, and the disassembling assembly 4 can change its axial length quickly to realize the quick installation and disassembly of the clamp. Thus, the adjusting function of the adjusting assembly 3 and the disassembling function of the disassembling assembly 4 are not affected by each other, so that the adjusting assembly 3 can change its axial length slowly to realize fine adjustment, and the disassembling assembly 4 can quickly switch between the first state and the second state without being affected by the change of the axial length of the adjusting assembly 3.

[0060] Among them, the disassembling assembly 4 can quickly realize the change of the axial length of the limiting section, and the adjusting assembly 3 can change its axial length in the limiting section, thereby realizing the adjustment of the locking strength of the clamp structure and the quick installation and disassembly of the clamp structure.

[0061] It should be understood that when the clamp structure needs to be locked, the dismounting assembly 4 is switched from the second state to the first state, the axial length of the limiting section is relatively reduced, and the adjusting assembly 3 is limited by the dismounting assembly 4 at one end close to the dismounting assembly 4, and the other end can push the second end 12 of the main body 1 to be close to the first end 11, so as to adjust the distance between the first end 11 and the second end 12 of the main body 1, and further adjust the locking strength of the main body 1. When the clamp structure needs to be disassembled, the dismounting assembly 4 is switched from the first state to the second state, at this time, the axial length of the limiting section is relatively increased, the adjusting assembly 3 can slide along the connecting rod 2 in the direction away from the second end 12, the distance between the first end 11 and the second end 12 is rapidly increased, and the clamp structure is quickly unlocked. Of course, in the clamp structure, the axial length of the adjusting assembly 3 can be adjusted first, and then the dismounting assembly 4 is switched from the second state to the first state, so that the clamp structure has different locking strengths.

[0062] Further, the length of the limiting section can be set to be greater than the sum of the thickness of the second end 12 and the maximum length of the adjusting assembly 3, so that in the adjustment range of the adjusting assembly 3, the first end 11 and the second end 12 can have different distances to ensure that the clamp has different locking strengths.

[0063] Referring to Figure 1 and Figure 2 , the first end 11 and the second end 12 of the main body 1 form an opening 13, and adjusting the distance of the opening 13 can realize the tightness adjustment of the main body 1. Specifically, one end of the connecting rod 2 is rotationally connected to the first end 11; the connecting rod 2 also penetrates the sunken groove 121 provided on the second end 12, when the clamp structure is disassembled, the second end 12 can be quickly separated from the connecting rod 2 to make the opening 13 quickly larger, thereby facilitating the disassembly of the clamp structure, and for the same reason, when the clamp structure needs to be installed, the connecting rod 2 can be directly slid into the sunken groove 121 from the gap of the sunken groove 121 to penetrate the second end 12, thereby facilitating the installation of the clamp structure. Of course, in other embodiments, one end of the connecting rod 2 can also be fixedly connected to the first end 11.

[0064] Referring to Figures 1 to 6 , the dismounting assembly 4 includes a first rotating piece 41, a guide groove 42 provided on the first rotating piece 41, and a guide rod 43 matched with the guide groove 42, wherein, as Figure 3 and Figure 4The guide rod 43 is also inserted into the connecting rod 2 to be axially limited by the connecting rod 2. It is understood that when the first rotating member 41 rotates, the guide rod 43 can be located at different positions of the guide groove 42, and the guide rod 43 is axially limited by the connecting rod 2 to realize the axial movement of the first rotating member 41 along the connecting rod 2 during rotation, so as to change the minimum axial distance between the disassembling assembly 4 and the first end 11, and to adjust the axial length of the limiting section. Here, the axial direction refers to the central axis direction of the connecting rod 2.

[0065] Further, the guide groove 42 includes a locking section 421 and a movable section 422, and the movable section 422 is located on the side of the locking section 421 close to the first end 11. Since the locking section 421 only extends along the circumference of the first rotating member 41, when the guide rod 43 cooperates with the locking section 421, the guide rod 43 and the locking section 421 will not slide relative to each other due to the contact force, and it is not easy to slide relative to each other due to the vibration of the pipeline, so as to ensure the relative locking between the first rotating member 41 and the guide rod 43, and avoid the relative sliding. The movable section 422 at least extends along the axial direction of the first rotating member 41, so that the first rotating member 41 can move axially to realize the quick disassembly and assembly of the clamp structure. It should be noted that when the guide rod 43 cooperates with the locking section 421, the disassembling assembly 4 is in the first state, and when the guide rod 43 cooperates with the end of the movable section 422 away from the locking section 421, the disassembling assembly 4 is in the second state.

[0066] Specifically, the locking section 421 only extends along the circumference of the first rotating member 41, and when the guide rod 43 is located in the locking section 421, the guide rod 43 is axially limited by the locking section 421, so that the axial position of the first rotating member 41 relative to the connecting rod 2 is fixed, and the end of the adjusting assembly 3 close to the disassembling assembly 4 is limited. By changing the axial length of the adjusting assembly 3 as a whole, the locking effect of the clamp structure can be changed.

[0067] Preferably, the movable section 422 is a spiral groove structure extending in the axial and circumferential directions. When the guide rod 43 moves along the movable section 422, the first rotating member 41 can move axially relative to the connecting rod 2, thereby realizing the quick disassembly and assembly of the clamp structure.

[0068] It should be understood that the movable section 422 is provided as a spiral groove structure, and during the locking of the clamp structure, the rotational movement of the first rotating member 41 is converted into axial movement through the inclined surface, so that the first rotating member 41 only needs to overcome a smaller component force along the inclined surface of the spiral groove, and does not need to directly resist the reaction force applied by the adjusting assembly 3 and the second end 12 of the main body 1, thereby being able to reduce the driving force required to drive the first rotating member 41 to move to a certain extent, and to realize more labor-saving locking of the clamp structure.

[0069] Further, in the embodiment, the active section 422 is a curved surface structure with a gradually changing lead angle, and the lead angle is smaller closer to the locking section 421. It can be understood that, during the locking process of the clamping structure, the force required to push the second end 12 closer to the first end 11 is greater as the distance between the first end 11 and the second end 12 gradually decreases, thereby making it more difficult for the second end 12 to approach the first end 11. Through the gradually changing lead angle described above, the change in axial distance gradually decreases when the first rotating member 41 rotates by the same angle during the locking process, thereby enabling the clamping structure to be locked more easily.

[0070] Referring to Figures 1 to 6 In order to make the guide rod 43 bear force more evenly and avoid the guide rod 43 being deformed due to cooperation with a single guide groove 42, in the embodiment, two guide grooves 42 are provided, and the two guide grooves 42 are rotationally symmetric about the center axis of the connecting rod 2, and the guide rod 43 penetrates the connecting rod 2 and is arranged in cooperation with the two guide grooves 42 at both ends. Thus, the force can be dispersed to avoid the guide rod 43 and the guide groove 42 from being damaged due to excessive force.

[0071] Preferably, the guide rod 43 is a cylindrical rod, and the central axis of the guide rod 43 is always perpendicular to the central axis of the connecting rod 2.

[0072] It can be understood that, since the two guide grooves 42 are rotationally symmetric about the center axis of the connecting rod 2, when the first rotating member 41 is in any axially movable position, the two ends of the guide rod 43 are located at the same position of the two guide grooves 42. For example, when one end of the guide rod 43 is located at the locking section 421 of the guide groove 42, the other end of the guide rod 43 is also located at the locking section 421 of the guide groove 42. Similarly, when one end of the guide rod 43 is located at the active section 422 of the guide groove 42, the other end of the guide rod 43 is also located at the active section 422 of the guide groove 42. The two ends of the guide rod 43 bear the same force, making the guide rod 43 bear force more evenly and the local force smaller.

[0073] Of course, in another embodiment, the guide rod 43 can also be provided with two, and the two guide rods 43 are fixed on both sides of the connecting rod 2, and the two guide rods 43 are arranged in cooperation with the two guide grooves 42, respectively, so that the force between the guide rod 43 and the first rotating member 41 can be evenly distributed to the two guide rods 43, making the single guide rod 43 bear smaller force, thereby avoiding the guide rod 43 being deformed due to cooperation with a single guide groove 42.

[0074] Referring to Figures 2 to 6In order to drive the first rotating member 41 more easily, a driving sleeve 5 is arranged outside the first rotating member 41, and the driving sleeve 5 is fixedly connected with the first rotating member 41, so as to drive the first rotating member 41 to rotate through the driving sleeve 5.

[0075] Specifically, the driving sleeve 5 is further provided with a plurality of force applying parts 50, so as to be more labor-saving in the process of rotating the driving sleeve 5.

[0076] It should be noted that the fixed connection between the driving sleeve 5 and the first rotating member 41 means that the relative position between the driving sleeve 5 and the first rotating member 41 is fixed, that is, the driving sleeve 5 and the first rotating member 41 rotate and slide synchronously.

[0077] Specifically, the driving sleeve 5 is provided with a through hole 51, the first rotating member 41 is provided with an insertion slot 52, and an insertion rod 53 penetrates through the through hole 51 and the insertion slot 52, so as to realize the fixed connection between the driving sleeve 5 and the first rotating member 41, and the driving sleeve 5 and the first rotating member 41 are assembled conveniently. Of course, in other embodiments, the fixed connection between the driving sleeve 5 and the first rotating member 41 can also be achieved by fasteners.

[0078] Further, in order to avoid the deformation of the insertion rod 53, the connection structure formed by the through hole 51, the insertion slot 52 and the insertion rod 53 can also be arranged in two groups or in a circumferential array.

[0079] Referring to Figures 2 to 8 In order to realize the quick disassembly and assembly of the clamp structure, the disassembly and assembly component 4 is axially limitedly connected with the adjusting component 3, so that the disassembly and assembly component 4 and the adjusting component 3 can slide synchronously along the axial direction, and the rotation adjustment of the disassembly and assembly component 4 and the rotation adjustment of the adjusting component 3 do not interfere with each other.

[0080] Specifically, the first rotating member 41 of the disassembly and assembly component 4 is provided with a circumferentially extending matching slot 6, and the adjusting component 3 comprises a rotating sleeve 31, and the rotating sleeve 31 is provided with a matching pin 7 inserted into the matching slot 6. Through the structure, the rotating sleeve 31 and the first rotating member 41 can rotate relative to each other.

[0081] When the first rotating member 41 moves axially, the adjusting component 3 can move away from or close to the second end 12 of the main body 1 synchronously through the cooperation of the matching slot 6 and the matching pin 7, so as to realize the quick unlocking or locking of the clamp structure.

[0082] It should be understood that the "the rotating sleeve 31 is provided with the matching pin 7 inserted into the matching slot 6" in the embodiment means that the matching pin 7 and the rotating sleeve 31 have a plug-in relationship (that is, can be axially limited). Of course, it can also be fixedly connected by fasteners, and the front end of the fastener is connected with the matching slot 6 in a sliding manner.

[0083] Further, it should be understood that the rotating sleeve 31 and the first rotating member 41 are respectively provided with a circumferentially extending matching groove 6 and a matching pin 7 inserted into the matching groove 6, so as to ensure that the rotation of the rotating sleeve 31 and the first rotating member 41 does not interfere with each other, and that the two can be synchronously axially moved.

[0084] Further, referring to Figure 4 and Figure 6 , the adjusting assembly 3 further comprises a second rotating member 32, an abutting member 33, a guide member 34 and a guide surface 35. The guide member 34, the guide surface 35 and the second rotating member 32 are located inside the accommodating cavity 311 of the rotating sleeve 31, and the second rotating member 32 is circumferentially limitedly connected with the rotating sleeve 31, so that the rotating sleeve 31 can synchronously drive the second rotating member 32 to rotate during the rotation of the rotating sleeve 31. The guide surface 35 is a helical surface structure, the guide member 34 is slidably connected with the guide surface 35, the guide member 34 is arranged on the abutting member 33, and the guide surface 35 is arranged on the second rotating member 32. When the rotating sleeve 31 drives the second rotating member 32 to rotate, the guide member 34 abuts against different positions of the guide surface 35, so that the abutting member 33 can axially slide along the connecting rod 2, the axial length of the adjusting assembly 3 can be adjusted, and the distance between the first end 11 and the second end 12 can be further adjusted. In addition, the guide surface 35 is arranged as a helical surface, so that it is more labor-saving to adjust the locking of the second rotating member 32 and the clamp structure.

[0085] It should be understood that the guide member 34 and the guide surface 35 are arranged on the second rotating member 32 and the abutting member 33 respectively, so that the second rotating member 32 can drive the abutting member 33 to axially slide along the connecting rod 2 during the rotation of the second rotating member 32.

[0086] Further, the adjusting assembly 3 further comprises a plurality of grooves 36 arranged on the guide surface 35, so that when the guide member 34 cooperates with the grooves 36 and slides towards the guide surface 35, the abutting member 33 and the second rotating member 32 will move towards the direction of moving away from each other.

[0087] It should be understood that the grooves 36 arranged on the guide surface 35 can not affect the sliding of the guide member 34 along the guide surface 35 to drive the abutting member 33 and the second rotating member 32 to move away from each other, and can also make the second rotating member 32 stop rotating. When the abutting member 33 abuts against the second end 12 of the main body 1, the guide member 34 can be clamped into the groove 36, so as to further increase the stability of the abutting member 33 and the locking effect of the clamp structure.

[0088] Embodiment Two

[0089] The difference between the embodiment and the embodiment one is that:

[0090] Referring toFigure 9 In this embodiment, the active section 422 comprises a first section 4221 and a second section 4222, wherein the second section 4222 is located between the first section 4221 and the locking section 421, and the lead angle of the first section 4221 is greater than the lead angle of the second section 4222.

[0091] By setting the active section 422 to have the first section 4221 and the second section 4222 with different lead angles, when the guide rod 43 moves in the first section 4221, the first rotating member 41 can move axially at a high speed, so that the fast disassembly and assembly of the clamp structure can be realized; when the guide rod 43 moves in the second section 4222, the first rotating member 41 can move axially at a relatively slow speed, and the component force of the first rotating member 41 along the inner wall surface (inclined surface) of the second section 4222 is also relatively small, so that the first rotating member 41 is more labor-saving.

[0092] Referring to Figures 1 to 6 In order to realize the fast disassembly of the clamp structure, the axial length of the first section 4221 is greater than the axial length of the second section 4222.

[0093] Embodiment Three

[0094] The difference between the embodiment three and the embodiment one and the embodiment two is that:

[0095] Referring to Figure 10 The adjusting assembly 3 comprises a threaded sleeve 37 and an abutting member 33, wherein the threaded sleeve 37 is sleeved outside the abutting member 33 and is in threaded connection with the abutting member 33, so that the axial length of the adjusting assembly 3 can be changed by the threaded connection between the threaded sleeve 37 and the abutting member 33.

[0096] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the range of protection of the utility model, and any non-essential changes and replacements made by the person skilled in the art on the basis of the utility model all belong to the range of protection required by the utility model.
