Description

Technical Field

[0001] The invention belongs to the technical field of support frames, and in particular relates to a support frame device that provides a rated outward thrust in a shell cavity. Background Art

[0002] Some shell products require the assembly of conformable layers in the shell cavity. Such shell products generally have the following characteristics: (1) The shell cavity is a rotating body or a special-shaped body; (2) The shell cavity is small, deep and sealed at one end, and the shell needs to be turned over during the layer assembly process; (3) The layers are bonded to the shell inner wall with glue, the layers are heavy and have a soft surface. These characteristics require that after the layers are bonded, appropriate pressure should be applied to each layer in a timely manner to fix them until the glue solidifies.

[0003] In the prior art, a push rod is used to fix the layers. This method has disadvantages: first, each push rod can only fix two opposite layers, which is inconvenient to operate and inefficient; second, the applied pressure cannot be quantified, and the applied pressure is often insufficient. When the shell is turned over, the layers often slide, or the pressure is too high, which will leave an indentation on the surface of the layer, affecting the quality of the layer fixation. Summary of the invention

[0004] In view of the deficiencies existing in the related art, the present invention provides a support frame device that provides a rated outward thrust in the shell cavity, so as to solve the problems of low efficiency of the top rod fixing the layer and poor quality of the indentation on the layer surface.

[0005] The present invention provides a support frame device for providing a rated outward thrust in a housing cavity, comprising:

[0006] The support frame comprises a ring body and two fixing frames, wherein the two fixing frames are respectively fixed to the upper and lower end surfaces of the ring body;

[0007] A guide assembly is arranged in the ring body, comprising an axial guide assembly and a plurality of radial guide members, wherein the axial guide assembly is located in the central axial direction of the ring body and penetrates the two fixing frames, and the plurality of radial guide members are radially arranged around the axial guide assembly;

[0008] A plurality of thrust assemblies, each of which is radially arranged corresponding to a radial guide member,

[0009] One end of each of the thrust assemblies is fixed to the corresponding radial guide, and the other end thereof penetrates through and extends out of the ring body;

[0010] An operating member is installed at one end and / or the other end of the axial guide assembly; when the operating member is rotated, the force is transmitted to the radial guide member through the axial guide assembly in turn after reversing and then to the thrust assembly, and the ends of multiple thrust assemblies are in contact with the shell cavity to provide outward thrust to the shell.

[0011] The technical solution realizes supporting multiple layers at a time, and solves the problems of low efficiency in fixing the layers and indentations on the surface of the layers.

[0012] In some embodiments, the axial guide assembly includes:

[0013] A guide rod, wherein the guide rod is provided with positive and negative threads;

[0014] A compression spring is sleeved on the guide rod;

[0015] Two conical sleeves are respectively sleeved on the positive and negative threads of the guide rod and are located at both ends of the compression spring;

[0016] Two limiting sleeves are respectively sleeved on the positive and negative threads at both ends of the guide rod and are located outside the two conical sleeves. The two ends of the guide rod are respectively fixed to the fixing frame through the two limiting sleeves, and the operating member is installed on the limiting sleeves;

[0017] The operating member is rotated to drive the guide rod to rotate, and the two limit sleeves simultaneously move backward along the guide rod, and the compression spring releases elastic energy to push the two conical sleeves to pop open, providing an axial-to-radial force to the radial guide member. This embodiment realizes the transformation of force from axial to radial.

[0018] In some embodiments, a plurality of radial guides are arranged around the conical sleeve, the inner side of the radial guide matches the conical shape of the conical sleeve, the two conical sleeves move in opposite directions to convert the axial force into a radial force to push the radial guide assembly to provide a radial thrust to the thrust assembly, and when the two conical sleeves move relative to each other, the center of the housing cavity of the radial guide assembly is folded. This embodiment realizes the transmission of force in the radial direction.

[0019] In some embodiments, each of the thrust assemblies comprises:

[0020] A connecting rod, one end of which is fixed to the radial guide member, and the other end of which penetrates the ring body and extends out of the ring body;

[0021] A return spring, sleeved on the connecting rod and located between the radial guide and the ring body;

[0022] The supporting spring is installed at the end of the connecting rod located outside the ring body; this embodiment realizes the thrust to the housing cavity.

[0023] In some embodiments, the positions where the two fixing frames are fixed to the end surface of the ring body and the intersection point where the connecting rod passes through the ring body are not on the same vertical line. This embodiment improves the strength of the device.

[0024] In some embodiments, the connecting rod is retractable. This embodiment realizes that the thrust on the layer can be adjusted and is suitable for special-shaped shells.

[0025] In some embodiments, the connecting rod is a support rod and a sleeve rod screwed together. This embodiment enables the length adjustment of the connecting rod.

[0026] In some embodiments, the support spring is rotatably connected to the connecting rod. This embodiment enables the support spring to adjust its angle, so that the support frame device can adapt to the special-shaped housing.

[0027] In some embodiments, the housing cavity is circular.

[0028] In some embodiments, the shell cavity is elliptical. When the shell cavity is elliptical, the lengths of the plurality of connecting rods are different.

[0029] Based on the above technical solution, a support frame device in an embodiment of the present invention provides a rated outward thrust in the shell cavity, which solves the problems of low efficiency of the top rod fixing the layer and poor quality of the indentation on the surface of the layer.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by terms such as "center", "lateral", "longitudinal", "up", "down", "top", "bottom", "inside", and "outside" are the orientations or positional relationships shown, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1-Figure 2 As shown, the present invention provides a support frame device for providing a rated outward thrust in a housing cavity, comprising: a support frame body 10, a guide assembly 20, a plurality of thrust assemblies 30 and an operating member 40, wherein

[0039] The support frame body 10 includes a ring body 11 and two fixing frames 12. The two fixing frames 12 are respectively fixed to the upper and lower end surfaces of the ring body 11. As shown in this embodiment, the two ends of the two ring bodies 12 are fixed to the upper and lower end surfaces of the ring body 11 by screws 13. When in use, the support frame body 10 is placed in the shell cavity, and the central axis of the ring body 11 is parallel to or coincides with the central axis of the shell.

[0040] The guide assembly 20 is arranged in the ring body 11, and includes an axial guide assembly 21 and a plurality of radial guide members 22. The axial guide assembly 21 is located in the central axis of the ring body 11 and penetrates the two fixed frames 12. The plurality of radial guide members 22 are radially arranged around the axial guide assembly 21. When working, the guide assembly 20 converts the axial force into a radial force.

[0041] A plurality of thrust assemblies 30 are provided, each of the thrust assemblies 30 is radially arranged corresponding to a radial guide member 22, one end of each thrust assembly 30 is fixed to the corresponding radial guide member 22, and the other end passes through and extends out of the ring body 11; it can be understood that the plurality of thrust assemblies 30 provide a plurality of supporting points, and when working, the force is transmitted to the thrust assembly 30 through the guide assembly 20, and the thrust assembly 30 applies a sustainable force to the layer in the shell cavity to fix the layer in the shell cavity.

[0042] To further illustrate, the support frame device has a plurality of thrust assemblies 30, which can fix a circle of layers around the shell cavity at a time.

[0043] The operating member 40 is installed at one end and / or the other end of the axial guide assembly 20; by rotating the operating member, the force is sequentially transmitted to the radial guide member through the axial guide assembly after reversing and then to the thrust assembly, and the ends of the multiple thrust assemblies are in contact with the housing cavity to provide an outward thrust to the housing. It is understandable that one or two operating members 40 can be installed. When in use, operating one operating member 40 can drive the axial guide assembly 21; installing two is convenient for operation from one end of the support frame device.

[0044] To further explain, after the operating member 40 is rotated in one direction, the thrust assembly 30 moves into the shell cavity, applying thrust to the layer in the shell cavity until the layer is fixed in the shell cavity. If the force applied at this time is too small, the operating member 40 continues to be rotated. If the force applied is too large, the operating member 40 is rotated in the opposite direction.

[0045] The above exemplary embodiment realizes fixing a plurality of layers to the shell cavity at one time, thereby solving the problems of low efficiency of fixing the layers by the push rod and poor quality of indentations on the surface of the layers.

[0046] like Figure 2 As shown, in some embodiments, the axial guide assembly 21 includes:

[0047] A guide rod 211, wherein the guide rod 211 is provided with positive and negative threads;

[0048] The compression spring 212 is sleeved on the guide rod 211 ; it can be understood that the compression spring 212 is always in a compressed state.

[0049] The two conical sleeves 213 are respectively sleeved on the positive and negative threads of the guide rod 211 and are located at both ends of the compression spring 212; when the operating member 40 is rotated and the two conical sleeves 213 move in the opposite direction along the guide rod 211, the compression spring 212 between the two conical sleeves 213 is bounced open, releasing elastic energy, and pushing the radial multiple radial guide members 22 to move outward until the thrust assembly 30 acts on the layer. The thrust assembly 30 is subjected to a balance between the reaction force of the layer and the thrust. The guide rod 211, the compression spring 212, and the two conical sleeves 213 are subjected to a force balance and remain relatively still. If the operating member 40 continues to be rotated, the two conical sleeves 213 will not continue to move.

[0050] Further, the distance between the end of the thrust assembly 30 facing the layer and the layer determines the compression amount of the compression spring 212. According to Hooke's law, the greater the distance between the layer and the thrust assembly 30, the greater the compression amount of the compression spring 212.

[0051] The two limit sleeves 214 are respectively sleeved on the positive and negative threads at both ends of the guide rod 211 and are located on the outside of the two conical sleeves 213. The two ends of the guide rod 211 are respectively fixed to the fixing frame 12 through the two limit sleeves 214. As shown in this embodiment, the limit sleeve 214 is fixed in the hole on the fixing frame 12, and the operating member 40 is installed on the limit sleeve 214. It can be understood that a limit sleeve 214 is provided at the outer end of each conical sleeve 213, and the limit sleeve 214 prevents the conical sleeve 213 from being bounced out of the guide rod 211.

[0052] The operating member 40 is rotated to drive the guide rod 211 to rotate, and the two limit sleeves 214 move backward along the guide rod 211 at the same time. The compression spring releases elastic energy to push the two conical sleeves 213 to pop open, providing an axial-to-radial force to the radial guide member 22.

[0053] The above exemplary embodiments realize the reversal of force from axial to radial direction.

[0054] like Figure 2 As shown, in some embodiments, a plurality of radial guides 22 are arranged around the conical sleeve 213. As shown in this embodiment, 8 radial guides 22 are arranged around the conical sleeve 213. The inner side surface of the radial guide 22 matches the conical shape of the conical sleeve 213. It can be understood that the inner side surface of the radial guide 22 clamps the two conical sleeves 213. The two conical sleeves 213 move in reverse to convert the axial force into a radial force to push the radial guide assembly to provide a radial thrust to the thrust assembly 30. When the two conical sleeves 213 move relative to each other, the center of the housing cavity of the radial guide assembly 22 is folded. It can be understood that when the two conical sleeves 213 are ejected, a plurality of radial guides 22 move toward the layer direction at the same time.

[0055] The above exemplary embodiments realize the reversal of force from axial to radial direction.

[0056] like Figure 1-2 As shown, in some embodiments, each of the thrust assemblies 30 includes:

[0057] The connecting rod 31 has one end fixed on the radial guide 22, and the other end passes through the ring body 11 and extends out of the ring body 11; as shown in this embodiment, a through hole is opened on the ring body 11, and a hole is opened on the outer side of the radial guide. During installation, the through hole of the ring body 11 is aligned with the outer side surface of the radial guide, and the connecting rod is passed through the through hole and inserted into the hole.

[0058] The return spring 32 is sleeved on the connecting rod 31 and is located between the radial guide 22 and the ring body 11; when the radial guide 22 pushes the thrust assembly 30 to move in the direction of the layer, the return spring 32 is compressed.

[0059] The support spring 33 is installed at the end of the connecting rod 31 located outside the ring body 11; it can be understood that the support spring 33 is in contact with the layer, and the size and shape of the support spring 33 can be determined according to the size and shape of the layer.

[0060] Furthermore, when disassembling the support frame device, the operating member 40 is rotated, and the radial guide member 22 moves inward under the action of the return spring 32, driving the support spring sheet 33 to separate from the layer sheet, and then the support frame device is taken out from the housing cavity.

[0061] The above exemplary embodiments enable the support frame device to provide a quantified thrust to the layer.

[0062] like Figure 1-2 As shown, in some embodiments, the portion where the two fixing frames 12 are fixed to the end surface of the ring body 11 and the intersection point where the connecting rod 31 passes through the ring body 11 are not on the same vertical line. It can be understood that the fixed connection portion between the fixing frame 12 and the ring body 11 and the hole where the connecting rod 31 passes through the ring body 11 are staggered to improve the strength of the ring body 11. This embodiment improves the strength of the support frame device and makes the structure more stable.

[0063] like Figure 1-2As shown, in some embodiments, the connecting rod 31 is retractable. It is understandable that the length of the connecting rod 31 can be adjusted. Furthermore, the connecting rod 31 can be adjusted in length, and all the connecting rods 31 can be adjusted uniformly, in order to obtain a quantitative force between the end of the thrust assembly and the layer, to avoid insufficient thrust causing the layer to slide or excessive thrust causing the layer to be crushed; in addition, the length of the connecting rod 31 can also be adjusted by only a few of the connecting rods 31 to adapt to shells of irregular shapes. This implementation realizes the quantitative adjustment of thrust and adapts to special-shaped shells, such as elliptical shells.

[0064] like Figure 1-2 As shown, in some embodiments, the connecting rod 31 is a support rod 311 and a sleeve rod 312 that are screwed together. During installation, the support rod 311 is inserted into the sleeve rod 312, the end of the support rod is connected to the support spring 33, and the return spring 32 is sleeved on the sleeve rod. This embodiment realizes that the length of the connecting rod 31 is adjustable.

[0065] like Figure 1-2 As shown, in some embodiments, the connecting rod 31 and the supporting spring 33 are rotatably connected. As shown in this embodiment, the connecting rod 31 and the supporting spring 33 are connected by a ball 34, the ball 34 is buried in the end face of the connecting rod 31, the threaded hole on the ball 34 faces the mouth of the ball nut 35, and the supporting spring 33 is fixed on the ball 34 by a countersunk screw 36; the ball nut 35 is installed on the connecting rod 31, the ball 34 is located in the ball socket set on the end face of the connecting rod 31, and the supporting spring 33 can swing within a certain angle under the action of the ball 34. The swinging back and forth of the supporting spring 33 within a certain angle can adapt to the special-shaped shell and improve the applicability of the supporting frame.

[0066] like Figure 1-2 As shown, in some embodiments, the operating member 40 is a handle.

[0067] In some embodiments, the housing cavity is circular. It is understandable that when the lengths of the connecting rods 31 are the same, the housing cavity is circular.

[0068] In some embodiments, the housing cavity is elliptical, and when the housing cavity is elliptical, the lengths of the plurality of connecting rods 31 are different. The connecting rod 31 is manually screwed together with the length of the support rod 311 and the sleeve rod 312. This embodiment realizes the applicability of the device.

[0069] Through the description of multiple embodiments of a support frame device for providing a rated outward thrust in a housing cavity of the present invention, it can be seen that the present invention has at least one or more of the following advantages:

[0070] 1. The present invention solves the problem of low efficiency of fixing the layers by the mandrel and poor quality of indentations on the surface of the layers, and realizes fixing multiple layers to the shell cavity at one time;

[0071] 2. The thrust assembly of the present invention has an adjustable length and an adjustable end angle, and is suitable for rotating bodies or irregular bodies with regular shapes, and has high applicability;

[0072] 3. The present invention can obtain controllable quantitative thrust by adjusting the length of the thrust assembly to control the distance between the support spring and the layer, thereby avoiding the layer from sliding due to insufficient thrust or the layer from being crushed due to excessive thrust;

[0073] 4. The present invention can retract the thrust assembly by rotating the guide rod, which is very convenient for removal.

[0074] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0075] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
