[0001] The utility model relates to the technical field of nut locking, in particular to a flange-type tooth-belly locking nut seat and an installation structure. Background Art

[0002] At present, for the installation and connection of some components, mating nuts and bolts are often used for connection. However, for some occasions with rapid and high-frequency vibration, conventional nuts are difficult to withstand such rapid and high-frequency vibration of such intensity. During use, the problem of nut loosening is likely to occur, and the installation and connection of components cannot be achieved stably, firmly and reliably.

[0003] For example, during the rapid nail driving of a pallet nailer in use, for the installation and connection of the nailer, if ordinary nuts and bolts are used for connection, then during the rapid and high-frequency vibration nail driving process, the nuts will loosen, resulting in the situation that the nailer is not firmly installed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that ordinary nuts will loosen during high-frequency vibration in the prior art, and a new flange-type tooth-belly locking nut seat and an installation structure are proposed.

[0005] In order to achieve the above purpose, as the first aspect of the utility model, the following technical scheme is adopted:

[0006] A flange-type tooth-belly locking nut seat and an installation structure, including a nut part and a connecting part. The nut part is provided with a threaded hole, an axial slit is formed in the nut part, a radial slit connected to the axial slit is further formed in the nut part, connecting holes for jointly cooperating to lock the nut part are respectively formed on the nut part on both sides of the axial slit, and the connecting part is connected to the nut part and extends radially out of the nut part.

[0007] In some embodiments, at least one end of the axial slit is connected to the radial slit. The axial slit extends inward along the radial direction and penetrates the inner ring thread wall of the nut part close to it, and the axial slit extends outward along the radial direction and penetrates the outer wall of the nut part.

[0008] Preferably, one end of the axial slit is connected to the radial slit in a communicating manner, and the other end of the axial slit penetrates one end of the nut part.

[0009] In some embodiments, at least one radial slit is provided. The radial slit extends at least inward along the radial direction to the inner ring thread wall of the nut part close to it, and the radial slit extends outward along the radial direction to the outer wall of the nut part.

[0010] Preferably, the radial slit extends radially inwardly to a distal inner thread wall of the nut portion.

[0011] In some embodiments, the connecting portion is configured as a connecting flange, and the connecting flange is connected to an end of the nut portion away from the axial slit.

[0012] As a second aspect of the utility model, a mounting structure is also provided, which includes the above-mentioned flange-type thread-flank locking nut seat, and also includes a pressure rod and a pressure seat, the pressure rod is threadedly connected to the nut part, the head of the pressure rod extends out of one end of the nut part and is configured as an operating end, the root of the pressure rod extends out of the other end of the nut part and is configured as a radially protruding chassis, the pressure seat is provided with an accommodating cavity to prevent the chassis from axially escaping, the chassis is installed in the accommodating cavity and can be driven by the operating end to rotate in the accommodating cavity while axially pressing the pressure seat.

[0013] In some embodiments, an elastic seat cushion is embedded in the bottom of the pressure seat, and the elastic seat cushion protrudes out of the bottom of the pressure seat.

[0014] Preferably, the bottom of the elastic seat cushion is provided with a concave cavity, and the flange around the concave cavity is configured as a pressed edge portion.

[0015] In some embodiments, the pressure seat includes a base and a connecting end cover, the connecting end cover is detachably connected to the top of the base, the accommodating cavity is constructed between the connecting end cover and the top of the base, the elastic seat pad is embedded in the base, and the chassis is accommodated in the accommodating cavity.

[0016] Compared with the prior art, the utility model provides a flange-type thread-flank locking nut seat, which has the following beneficial effects:

[0017] By providing the axial slits, radial slits and connecting holes on the nut portion, after tightening the peripheral fastener, such as a screw, in the connecting hole, the component threadedly connected to the nut, such as a compression rod in the mounting structure, can be firmly held;

[0018] By setting the connection part on the nut part, the nut part can be connected to the peripheral fixing member, so as to realize the fixation of the flange-type thread-flank type locking nut seat, and then the parts connected with the nut thread, such as the pressure rod in the installation structure, can be reliably fixed;

[0019] It can be seen that the flange-type threaded locking nut seat can, on the one hand, firmly hold the parts connected with its threads, and on the other hand, fix itself to the peripheral fixed component. In this way, even in the process of high-frequency vibration, the flange-type threaded locking nut seat will not loosen, and can adapt to the installation and fixation of nailing machines in high-frequency vibration environments such as pallet nailing machines;

[0020] The installation structure of the present utility model adopts a flange-type tooth-belly locking nut seat, and is also provided with a pressure rod and a pressure seat with a chassis. The chassis can rotate inside the pressure seat and press down the pressure seat downward. In this way, the peripheral components to be fixed, such as a nail gun, can be pressed and fixed under the pressure seat (of course, the bottom of the nail gun is provided with peripheral supporting components). As the operating end is rotated, the pressure rod rotates and moves downward, thereby driving the chassis to rotate inside the pressure seat and press down the pressure seat, so as to gradually press and fix the nail gun by the pressure seat.

[0021] It should be noted that during the pressing and fixing process, the peripheral fasteners, such as screws, are in a loosened state. After the pressing and fixing is in place, they can be locked in the connecting holes, so that the nut part firmly holds and locks the pressure rod. Brief Description of the Drawings

Detailed Description of the Embodiment

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0029] In the description and claims of this application, a certain component 1, a certain component 2, etc. are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0030] Refer to the attached Figures 1-4 , a specific embodiment of a flange-type tooth-bellied locking nut seat and an installation structure is provided, wherein the flange-type tooth-bellied locking nut seat 100 mainly includes the following components: a nut portion 1 and a connecting portion 2, and the connecting portion 2 is connected to the nut portion 1 and radially extends out of the nut portion 1. An installation hole is provided on the connecting portion 2 for fixing the entire flange-type tooth-bellied locking nut seat 100 to an external fixing member 3.

[0031] The nut portion 1 is provided with a threaded hole 4, and the threaded hole 4 penetrates through both ends of the nut portion 1. The nut portion 1 is provided with an axial slit 5, and the nut portion 1 is further provided with a radial slit 6 connected to the axial slit 5. Connecting holes 7 for jointly cooperating to lock the nut portion 1 are respectively provided on the nut portion 1 on both sides of the axial slit 5. By screwing an external fastener, such as a screw (not shown), into the connecting hole 7, the nut portion 1 can be locked.

[0032] Among them: The purpose of setting the axial slit 5 is to cut the nut portion 1 at this place to form two symmetrical parts; the setting of the radial slit 6 is mainly to enable the two cut parts to have a certain tightening elasticity, and can be connected and firmly locked by an external fastener.

[0033] Through the cooperative setting of the above-mentioned components, the flange-type tooth-bellied locking nut seat 100 can lock the nut portion 1 by screwing an external fastener into the connecting hole 7; and the setting of the connecting portion 2 can fix the flange-type tooth-bellied locking nut seat 100.

[0034] Among them, for the specific structure of the axial slit 5, there are multiple implementable ways. In this embodiment, the radial span of the axial slit 5 extends inward and penetrates the inner ring thread wall 8 near the nut portion 1, and the radial span of the axial slit 5 extends outward and penetrates the outer wall 9 of the nut portion 1. It can be understood that through the above settings, that is, the axial slit 5 only penetrates one side wall thickness of the nut portion 1 in the radial direction, so there is an axial slit on the nut portion 1. Specifically, for the inner ring thread wall 8 and the outer wall 9 near, reference can be made to Figure 4 . Of course, in other embodiments, the axial slit 5 is allowed to be constructed with 2, 3, or even multiple slits. Specifically, it can be determined according to the actual situation.

[0035] In this embodiment, one end of the axial slit 5 is connected to the radial slit 6 in a communicating manner, and the other end of the axial slit 5 penetrates one end of the nut portion 1. It can be understood that in this embodiment, an axial slit 5 is provided, and after one end of the axial slit 5 penetrates one end of the nut portion 1, the other end of the axial slit 5 is also vertically connected to the radial slit 6. After being vertically connected to the radial slit 6, the nut portion 1 on both sides of the axial slit 5 has a tightening elastic force, so that the nut portion 1 can be tightened by screwing in the outer fastener into the connection hole 7.

[0036] For the radial slit 6, there are also multiple implementable ways. In this embodiment, one radial slit 6 is provided. According to the orientation as Figure 1 shown, the radial slit 6 is provided below the axial slit 5.

[0037] For the radial inward extension depth of the radial slit 6, it can be at least extended to the inner ring thread wall 8 near the nut portion 1. In order to make the nut portion 1 on both sides of the axial slit 5 have better tightening elastic force as much as possible, in this embodiment, the radial slit 6 extends radially inward to the inner ring thread wall 10 far from the nut portion 1. Among them, the inner ring thread wall 10 far from can be specifically referred to in the appendix Figure 4 at the shown position.

[0038] For the specific structure of the connecting portion 2, in this embodiment, the connecting portion 2 is configured as a connecting flange. The connecting flange is connected to one end of the nut portion 1 far from the axial slit 5 and is an integral structure with the nut portion 1. And installation holes are also provided on the connecting flange for fixing the flange-type tooth abdomen locking nut seat 100 as a whole to the outer fixing member 3. Of course, in other embodiments, the connecting portion 2 can be provided as multiple connecting blocks. The multiple connecting blocks protrude radially from the nut portion 1, and each connecting block is provided with an installation hole, and the connecting blocks are circumferentially distributed along the nut portion 1.

[0039] As the flange-type tooth-bellied locking nut seat 100 of the present utility model, considering that it needs to be fixed to the bottom of the peripheral fixing member 3 by the connecting portion 2, and the peripheral fixing member 3 is basically a plate body, therefore, when designing the flange-type tooth-bellied locking nut seat 100, in this embodiment, the distance between the radial slit 6 and the connecting flange should be at least equal to or greater than the thickness of the plate body, so that the radial slit 6 extends out of the plate body, so that the axial slit 5 and the connecting hole 7 can both extend out of the plate body for convenient operation.

[0040] The present utility model also discloses an installation structure provided with the above-mentioned flange-type tooth-bellied locking nut seat 100. Refer to the attached Figures 1-4 , in this embodiment, the installation structure includes a pressure rod 11 and a pressure seat 12. The pressure rod 11 is threadedly connected to the nut portion 1. The head of the pressure rod 11 extends out of one end of the nut portion 1 and is connected with an operation end 13. For the convenience of operation, the operation end 13 is an operation handwheel, and the operation handwheel is fixedly connected to the top end of the pressure rod 11.

[0041] The root of the pressure rod 11 extends out of the other end of the nut portion 1 and is configured as a radially protruding chassis 14. The pressure seat 12 is provided with a receiving cavity 15 for preventing the chassis 14 from axially disengaging. The chassis 14 is installed in the receiving cavity 15 and can rotate axially and press the pressure seat 12 tightly in the receiving cavity 15 under the drive of the operation end 13. It should be noted that when the operation end 13 rotates, it drives the pressure rod 11 to screw into the threaded hole 4 of the nut portion 1. Since the flange-type tooth-bellied locking nut seat 100 is fixed on the peripheral fixing member 3, the nut portion 1 will not move. At this time, the chassis 14 can rotate and press down the pressure seat 12. If there is a component to be fixed at this time, such as a nail gun is pressed under the pressure seat 12. Of course, there is a supporting component (not shown) at the bottom of the nail gun. In this way, as the operation end 13 is continuously rotated, the component to be fixed will be tightly pressed between the pressure seat 12 and the supporting component, realizing a temperature and reliable connection and fixation. Of course, the supporting component can further use fasteners to connect the component to be fixed and the supporting component, so that the installation is more firm and reliable.

[0042] It should be noted that, in order to enable the chassis 14 to rotate in the receiving cavity 15 and also have the required axial movement, the radial dimension of the receiving cavity 15 is slightly larger than the radial dimension of the chassis 14, and the height is also set according to the axial movement stroke and should be greater than the axial thickness of the chassis 14.

[0043] In order to avoid the clamping damage of the fixed parts as much as possible, the bottom of the press seat 12 is embedded with an elastic seat pad 16, and the elastic seat pad 16 protrudes out of the bottom of the press seat 12. In order to further reduce wear, the bottom of the elastic seat pad 16 is provided with a concave cavity 17, and the flange around the concave cavity 17 is configured as a pressing edge portion 18. The provision of the concave cavity 17 not only reduces the contact area and wear, but more importantly, avoids the elastic seat pad 16 from adhering to the fixed parts during disassembly and assembly.

[0044] As for the specific structure of the pressure seat 12, multiple deformation structures are allowed. In this embodiment, the pressure seat 12 includes a base 19 and a connecting end cover 20. The connecting end cover 20 is detachably connected to the top of the base 19. In this embodiment, it is preferably connected with conventional bolts. The accommodating cavity 15 is constructed between the connecting end cover 20 and the top of the base 19. The elastic seat pad 16 is embedded in the base 19, and the chassis 14 is accommodated in the accommodating cavity 15. Through such a setting, on the one hand, it is easy to construct the accommodating cavity 15, because the accommodating cavity 15 can be mainly processed on a separate component, that is, the connecting end cover 20. After installation and connection, the accommodating cavity 15 can be constructed between the connecting end cover 20 and the top of the base 19; on the other hand, after the accommodating cavity 15 is constructed, it can meet the rotation of the chassis 14 in the pressure seat 12, but will not drive the pressure seat 12 to rotate, so that it can avoid driving the fixed component when operating the operating end 13.

[0045] When installing the fixed component specifically, the pressure rod 11 and the nut part 1 have been threadedly connected and assembled into the above-mentioned installation structure. At this time, the connecting part 2 is connected to the peripheral fixing member 3 with fasteners to realize the fixation of the flange-type thread-belly locking nut seat 100; then the fixed component is placed between the supporting component and the pressure seat 12 below, and at the same time, the bottom of the fixed component is connected and fixed to the supporting component with fasteners, and then the operating end 13 is rotated to drive the chassis 14 at the root of the pressure rod 11 to rotate in the accommodating cavity 15 of the pressure seat 12 while axially pressing the pressure seat 12 downward. The pressure seat 12 is subjected to force, thereby pressing the fixed component below tightly until it is pressed into place; then the peripheral fasteners are screwed into the connecting hole 7 and gradually tightened, so that the nut part 1 gradually hugs the pressure rod 11, and the installation of the entire fixed component is completed.

[0046] It can be seen that the flange-type thread-belly locking nut seat and installation structure of the utility model will not cause the nut part to loosen when the fixed parts are installed, and it is difficult to loosen even in high-frequency vibration conditions, so the fixed parts can be reliably installed, and the overall structure is compact and simple, and the installation and fixing are convenient.

[0047] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
