Description

Technical Field

[0001] This utility model relates to the technical field of air compressor supporting equipment, and in particular to a multi-position adjustable air compressor air tank fixing bracket. Background Technology

[0002] The air compressor's matching air tank is a key energy storage component of the compressed air system. It requires a special bracket for fixing and limiting during unit assembly and centralized layout operations in the plant area. Existing air compressor tank mounting brackets use adjustable supports with bolt holes for positioning and adjustment. This requires repeated disassembly and tightening of the bolts, making the process cumbersome. The bolts are prone to loosening due to long-term vibration, resulting in insufficient tank stability. Furthermore, the lack of a double self-locking limit structure makes the air tank susceptible to displacement and impacts from the compressor's start-up and shutdown vibrations, posing a safety hazard. Therefore, there is an urgent need for a multi-position adjustable air compressor tank mounting bracket. Utility Model Content

[0003] Based on the technical problems in the background art, this utility model proposes a multi-position adjustable air compressor storage tank fixing bracket.

[0004] This utility model proposes a multi-position adjustable air compressor tank fixing bracket, comprising: a support plate, with four vertical plates on the top of the support plate; side plates, the ends of which are respectively fixed to the outer surfaces of the four vertical plates; top rods, the two ends of which are respectively fixed to the top of the four vertical plates; bottom plates, with which are respectively fixed to the outer surfaces of the side plates; top plates, with which are respectively fixed to the outer surfaces of the side plates; gear teeth, with which are respectively fixed at equal intervals to the top of the bottom plates; and a limiting mechanism, which is movably disposed in the gaps between the side plates.

[0005] Preferably, the limiting mechanism includes: a transverse rod, multiple transverse rods being movably disposed in the gaps between multiple side plates; a threaded ring, two threaded rings being threadedly sleeved on both ends of the transverse rod; a pressing plate, the pressing plate being fixedly sleeved on the end of the threaded ring; a large spring, one end of the large spring being fixedly disposed on the outer surface of the pressing plate; a compression ring, the outer surface of the compression ring being fixedly disposed on the other end of the large spring; and a rubber cover, the rubber cover being sleeved on the outer surface of the compression ring.

[0006] Preferably, the limiting mechanism further includes: a rotating disk, which is fixedly disposed at one end of the transverse rod; an end disk, which is fixedly disposed at the other end of the transverse rod; a limiting disk, which is fixedly sleeved at one end of the transverse rod; a toggle rod, the ends of which are fixedly disposed on the outer surface of the threaded ring; a movable rod, the ends of which are fixedly disposed on the outer surface of the compression ring; a frustum ring, two frustum rings, which are respectively fixedly sleeved at both ends of the transverse rod; and two pinions, which are respectively fixedly sleeved at both ends of the transverse rod.

[0007] Preferably, the bottom of the pinion is always engaged with the gear teeth at the top of the bottom plate, the four side plates are arranged in a square, the transverse rod is parallel to one part of the side plates, and the transverse rod is perpendicular to the other part of the side plates.

[0008] Preferably, the transverse rod is located between the bottom plate and the top plate, and four movable rods are distributed around the axis of the transverse rod, with the movable rods moving through the pressing plate.

[0009] Preferably, the rubber cover is located on the side of the bottom plate and the top plate, the large spring is movably sleeved around the periphery of the transverse rod, the axis of the movable rod is parallel to the axis of the large spring, and the four movable rods are arranged around the periphery of the large spring.

[0010] Preferably, the horizontal bar and the vertical plate are perpendicular, the side plate and the vertical plate are perpendicular, the top bar and the vertical plate are perpendicular, and the vertical plate is L-shaped.

[0011] The beneficial effects of this utility model are as follows: A gear and rack transmission pair is formed by the small gear and the evenly distributed gear teeth on the bottom plate. Rotating the rotating disk drives the horizontal rod to move continuously and steplessly along the length of the rack. The horizontal and vertical rods, arranged alternately, can freely form limiting cavities of different sizes, adapting to the clamping and positioning of air compressor tanks of various outer diameters on the market. One set of fixing brackets can complete the array-style placement and fixing of tanks of various specifications, saving the cost of custom mold making and welding for multiple specifications of brackets, and reducing the cost of equipment procurement and storage space. A toggle lever serves as the operating handle. Manually operating the lever drives the threaded ring to feed along the transverse rod. By changing the axial displacement of the threaded ring, the compression of the large spring is altered, quickly unlocking and locking the rubber cover. No wrenches, bolts, or other accessories are required throughout the process, simplifying the steps for gas tank replacement and position adjustment, and improving the efficiency of on-site assembly and rectification work. The small gear is constantly engaged and locked into the gear tooth groove, relying on the tooth meshing to achieve mechanical locking and restrict the spontaneous slippage of the transverse rod. Under normal conditions, the large spring continuously and elastically pushes and compresses the ring, causing the rubber cover to fit tightly against the bottom plate and the side wall of the top plate, forming static friction braking.

Detailed Implementation

[0014] Reference Figures 1 to 6 A multi-position adjustable air compressor air tank fixing frame includes: a support plate 1, with four vertical plates 2 on the top of the support plate 1; the support plate 1 is the overall ground bearing base of the device, and all parts of the machine and the air tank A to be fixed are placed on the upper surface of the support plate 1 to achieve concentrated load bearing; the four vertical plates 2 are vertically fixed to the four corners of the upper surface of the support plate 1, and the L-shaped vertical plates 2 serve as a vertical support frame, providing fixed installation fulcrums for the side plates 3 and the top rod 4, building a square three-dimensional installation frame body, and defining the installation boundary and installation height of the entire limiting mechanism.

[0015] In this invention, side plates 3 are fixedly mounted at their ends on the outer surfaces of four vertical plates 2. Multiple side plates 3 are arranged and fixed laterally along the sidewalls of the vertical plates 2, with uniform gaps reserved between adjacent side plates 3. These gaps serve as guide grooves for the sliding of the transverse rods 7. Simultaneously, the outer walls of the side plates 3 provide a flat welding base for the bottom plate 5 and top plate 8, allowing the bottom plate 5 and top plate 8 to be suspended parallel to each other outside the side plates 3. Top rods 4 are fixed at their ends on the tops of the four vertical plates 2. The four top rods 4 are connected end-to-end and fixed to the tops of the four vertical plates 2, forming a closed rectangular frame at the top. This frame constrains the relative positions of the four vertical plates 2 from the top, offsetting the lateral tension caused by the compression of the gas tank A, preventing the vertical plates 2 from deforming outwards under external force, and improving the overall structural integrity and deformation resistance of the entire frame.

[0016] In this utility model, a bottom plate 5, and multiple bottom plates 5 are respectively fixedly disposed on the outer surface of multiple side plates 3; the bottom plate 5 is horizontally fixed in the lower half of the side plate 3, and the upper surface of each bottom plate 5 is evenly provided with installation positions for equidistantly arranging and fixing gear teeth 6. The bottom plate 5 serves as the installation carrier for the gear teeth 6, and its side wall can be in contact with the rubber cover 18 to generate static friction force, which together with the top plate 8 realizes the locking and positioning of the limiting mechanism; the top plate 8, and multiple top plates 8 are respectively fixedly disposed on the outer surface of multiple side plates 3; the top plate 8 is arranged parallel to the position directly above the corresponding bottom plate 5, and the two are coaxially corresponding. The lower side wall of the top plate 8 can also be in contact with the outer wall of the rubber cover 18. The top plate 8 and the bottom plate 5 vertically limit the range of motion of the rubber cover 18 to prevent the rubber cover 18 from vertically detaching, and cooperate with the bottom plate 5 to form a double friction braking surface.

[0017] In this invention, gear teeth 6 are fixedly and equidistantly arranged on the top of multiple bottom plates 5. All gear teeth 6 are evenly arrayed along the length of the bottom plate 5. A single set of gear teeth 6 is integrated with the bottom plate 5 to form a rack structure. The rack and pinion 20 mesh one by one, converting the circumferential rotation of the pinion 20 into the linear translation of the transverse rod 7 along the length of the bottom plate 5. The teeth are pre-limited after the transverse rod 7 moves by meshing. A limiting mechanism is movably arranged in the gap between multiple side plates 3. The entire limiting mechanism is inserted into the cavity gap formed by adjacent side plates 3. The pinion 20 and gear teeth 6 mesh to achieve a large range of positional movement. The large spring 15 elastically presses the rubber cover 18, causing the rubber cover 18 to press against the side wall of the bottom plate 5 and the top plate 8 to generate static friction and achieve self-locking. The positions of multiple limiting mechanisms can be flexibly adjusted to adapt to the clamping and fixing of gas tanks A with different outer diameters and different arrangement specifications.

[0018] In this utility model, the limiting mechanism includes: a transverse rod 7, multiple transverse rods 7 are movably arranged in the gaps between multiple side plates 3; the transverse rod 7 is the central main shaft of the entire limiting mechanism, the transverse rod 7 passes through the gaps between the side plates 3, and the outer wall of the rod body directly abuts against the arc outer wall of the gas storage tank A. Multiple transverse rods 7 are arranged in a crisscross pattern to surround and limit the tank body. All end fittings such as threaded rings 12, pressing plates 14, large springs 15, compression rings 16, frustum rings 19, and small gears 20 are sequentially inserted through both ends of the transverse rod 7, serving as all... The assembly reference shaft of the accessories; two threaded rings 12 are respectively threaded onto the two ends of the transverse rod 7; the inner wall of the threaded ring 12 has an internal thread, which matches and screws with the external threads at both ends of the transverse rod 7; the actuating rod 13 is fixed on the outer ring of the threaded ring 12; the external force rotates the actuating rod 13, which drives the threaded ring 12 to move back and forth along the axial direction of the transverse rod 7; the axial displacement of the threaded ring 12 changes the position of the pressing plate 14, thereby adjusting the compression deformation of the large spring 15, and indirectly controlling the clamping force of the rubber cover 18.

[0019] In this utility model, a pressing plate 14 is fixedly sleeved on the end of a threaded ring 12. The pressing plate 14 is coaxially fastened to the inner end face of the threaded ring 12. The plate surface has through circular holes matching the number of movable rods 17. The movable rods 17 pass through the circular holes to achieve sliding fit. When the threaded ring 12 moves axially, it synchronously drives the pressing plate 14 to move synchronously. The pressing plate 14 serves as a limiting support surface for one end of a large spring 15, pushing or releasing the large spring 15 to achieve compression and extension. One end of the large spring 15 is fixedly set on the outer surface of the pressing plate 14. The large spring 15 is loosely sleeved on the outside of the transverse rod 7. One end face is fixedly attached to the inner side of the pressing plate 14, and the other end is connected to the compression ring 16. It generates continuous elastic force by its own elastic deformation. Under normal conditions, the large spring 15 always remains in a compressed state and continuously applies a pushing force to the compression ring 16, making the rubber cover 18 generate a friction locking force.

[0020] In this invention, a compression ring 16 is fixedly mounted on the other end of a large spring 15 on its outer surface. The compression ring 16 is a ring-shaped structure with multiple movable rods 17 fixed to its outer wall. A rubber cover 18 is fitted onto the outer wall of the ring. The elastic force of the large spring 15 is evenly distributed and transmitted to the rubber cover 18 through the compression ring 16, causing the rubber cover 18 to press tightly against the side walls of the bottom plate 5 and the top plate 8, thus achieving braking and locking. The rubber cover 18 is fitted onto the outer surface of the compression ring 16. The rubber cover 18 is made of high-friction rubber material and covers the outer ring of the compression ring 16. Under the action of the elastic force of the large spring 15, it is tightly attached to the side walls of the bottom plate 5 and the top plate 8, locking the compression ring 16 and the transverse rod 7 in position by relying on the static friction of the contact surface. When the large spring 15 is compressed and the elastic force decreases, the friction between the rubber cover 18 and the plate decreases, thereby releasing the lock and allowing the transverse rod 7 to slide freely.

[0021] In this utility model, the limiting mechanism further includes: a rotating disk 9, which is fixedly installed at one end of the transverse rod 7; the rotating disk 9 is exposed on the outside of the frame and serves as a manually driven component. When the operator holds the rotating disk 9 and rotates it, it can directly drive the transverse rod 7 to rotate coaxially, and synchronously drive the small gears 20 assembled at both ends of the transverse rod 7 to rotate together, relying on the gear and rack to complete the translation adjustment of the transverse rod 7; and an end disk 10, which is fixedly installed at the other end of the transverse rod 7; the end disk 10 is sealed at the outermost end of the transverse rod 7, and its outer diameter is larger than the inner diameter of the small gear 20, limiting the small gear 20, frustum ring 19 and other components from the shaft end to prevent the end accessories from falling off the end of the transverse rod 7 and disintegrating during the rotation or sliding of the transverse rod 7.

[0022] In this invention, a limiting disc 11 is fixedly sleeved on one end of a transverse rod 7. The limiting disc 11 is fixed to the side of the transverse rod 7 near the rotating disc 9, separating the rotating disc 9 from the other end accessories, restricting the accessories from axially moving towards the rotating disc 9, and regulating the installation range of each part on the transverse rod 7. Multiple actuating rods 13 have their ends fixedly disposed on the outer surface of a threaded ring 12. These multiple actuating rods 13 are evenly distributed along the circumference of the threaded ring 12 and extend radially outward, forming an external operating handle, eliminating the need for special tools. Manually moving the lever 13 allows for easy rotation of the threaded ring 12, quickly adjusting the tension of the large spring 15 and unlocking the braking structure. Multiple movable rods 17 have their ends fixed to the outer surface of the compression ring 16. The movable rods 17 extend from the compression ring 16 towards the pressing plate 14 and pass through the pre-drilled hole in the pressing plate 14. The movable rods 17 are clearance-fitted with the hole wall of the pressing plate 14, providing directional guidance when the compression ring 16 moves under the thrust of the large spring 15, preventing radial displacement, tilting, or jamming of the compression ring 16.

[0023] In this invention, two frustum rings 19 are fixedly fitted onto the two ends of the transverse rod 7. The frustum rings 19 are positioned between the pinion 20 and the compression ring 16. One end of the frustum ring 19 has a conical surface abutting against the end face of the pinion 20, while the other end buffers and limits the compression ring 16, isolating the friction components and gear components to prevent them from rubbing against each other during operation. It also serves as an axial limiting and blocking effect. The flat surface of the frustum ring 19 abuts against the sides of the two side plates 3, which can position the transverse rod 7 and the side plates 3 at their overlapping positions. Two pinions 20 are fixedly fitted onto the two ends of the transverse rod 7. The pinions 20 and the transverse rod 7 are interference-fitted to achieve synchronous rotation. The gear teeth precisely mesh with the gear teeth 6 on the bottom plate 5. When the transverse rod 7 rotates with the rotating disk 9, the pinions 20 roll along the arrangement trajectory of the gear teeth 6, thereby driving the entire transverse rod 7 to move smoothly within the gap of the side plates 3.

[0024] In this invention, the bottom of the pinion 20 is always engaged with the gear teeth 6 on the top of the bottom plate 5. In the assembled state, the pinion 20 teeth continuously engage with the gaps in the gear teeth 6, maintaining engagement throughout the process without disengaging. Positioning is achieved through tooth engagement. After the rubber cover 18 releases its friction lock, the pinion 20 rotates and moves linearly along the gear teeth 6, precisely controlling the movement distance of the transverse rod 7. Once in position, the friction lock of the rubber cover 18, combined with the tooth engagement, achieves double limiting. The four side plates 3 are in a... The four side plates 3 are arranged in a square pattern. The horizontal rods 7 are parallel to one part of the side plates 3 and perpendicular to another part of the side plates 3. The four side plates 3 together form a square frame. The horizontal rods 7 are arranged in two groups, horizontal and vertical. The horizontal rods 7 are parallel to one group of side plates 3, and the vertical rods 7 are perpendicular to the group of side plates 3. The horizontal and vertical rods intersect to form multiple sets of rectangular limiting chambers. Each chamber can hold a single gas storage tank A, so that the gas storage tank A array is arranged in a regular manner.

[0025] In this invention, the transverse rod 7 is located between the bottom plate 5 and the top plate 8. The axis of the transverse rod 7 is located at the vertical center of the bottom plate 5 and the top plate 8. Equivalent gaps are reserved on the upper and lower sides to ensure that the rubber cover 18 fitted on the outside of the transverse rod 7 can contact the side walls of the upper and lower plates at the same time, and to limit the transverse rod 7 from tilting up and down due to the pressure of the can, thus constraining the vertical displacement of the transverse rod 7. Four movable rods 17 are distributed around the axis of the transverse rod 7. The movable rods 17 are movably inserted through the pressing plate 14. The four movable rods 17 are evenly arranged around the transverse rod 7 in a ring. The four-point limiting structure ensures that the extrusion ring 16 remains coaxial with the transverse rod 7 throughout the entire process. During the extension and retraction of the extrusion ring 16 driven by the large spring 15, the movable rods 17 slide smoothly along the holes of the pressing plate 14, preventing the extrusion ring 16 from tilting and the rubber cover 18 from failing due to uneven wear on one side.

[0026] In this invention, the rubber cover 18 is located on the sides of the bottom plate 5 and the top plate 8. The outer curved surface of the rubber cover 18 is in close contact with the upper side wall of the bottom plate 5 and the lower side wall of the top plate 8. The upper and lower sides simultaneously contact the plates to form a double friction surface, which greatly improves the locking friction force. Only after the large spring 15 is compressed and shortened and the elastic force decreases, the squeezing force between the rubber cover 18 and the plate decreases and the friction constraint force fails, so that the transverse rod 7 can be adjusted normally. The large spring 15 is movably sleeved on the periphery of the transverse rod 7. The axial direction of the movable rod 17 is parallel to the axial direction of the large spring 15. The four movable rods 17 are arranged around the periphery of the large spring 15. The large spring 15 is suspended on the outside of the transverse rod 7. The four movable rods 17 are arranged around the outside of the ring of the large spring 15. The four movable rods 17 form an outer protective limiting structure. When the large spring 15 is compressed and extended, the outer ring expansion deformation is restricted by the movable rods 17, which prevents the large spring 15 from being twisted or misaligned and stuck, and ensures that the spring force is evenly output along the axis of the transverse rod 7.

[0027] In this invention, the horizontal rod 7 and the vertical plate 2 are perpendicular, the side plate 3 and the vertical plate 2 are perpendicular, and the top rod 4 and the vertical plate 2 are perpendicular. The vertical plate 2 is L-shaped. The assembly relationship of all rods and the vertical plate 2 perpendicular to each other makes the whole frame form a standard orthogonal rectangular frame structure, with uniform force and regular space. The vertical plate 2 with L-shaped bending structure has two supporting surfaces, one side fixing the supporting plate 1 and the other side fixing the side plate 3 and the top rod 4. Compared with the straight plate structure, it has stronger bending resistance, effectively disperses the concentrated load brought by the loading of the gas storage tank A, prevents the corners of the frame from cracking and deforming under stress, and provides a stable and non-deformable installation reference frame for the adjustment and limit of the whole device.

[0028] In use, first, place the gas tank into the gap between the multiple horizontal bars 7, so that the multiple gas tanks are arranged in an array on the top of the support plate 1, and the gas tanks are limited by the multiple horizontal bars 7 and the side plate 3. During adjustment, push the lever 13 by hand to make the threaded ring 12, lever 13, pressing plate 14, large spring 15, compression ring 16, movable rod 17, and rubber cover 18 rotate synchronously. The threaded ring 12 rotates to move along the surface of the transverse rod 7. The compression ring 16, rubber cover 18, and large spring 15 only move axially and do not rotate circumferentially, increasing the distance between the threaded ring 12 and the bottom plate 5, and the distance between the pressing plate 14 and the bottom plate 5. The large spring 15 increases in length due to its own elasticity, and the tension of the large spring 15 reduces the elastic force on the compression ring 16, thus reducing the pressure of the rubber cover 18 on the bottom plate 5. The positive pressure on the outer surface of plate 5 reduces the static friction between rubber cover 18 and bottom plate 5. Then, the rotating disk 9 is turned by hand to make the transverse rod 7 and pinion 20 rotate synchronously. Since the pinion 20 is engaged with the gear teeth 6 at the top of bottom plate 5, the pinion 20 rotates to move along the axial direction of bottom plate 5. The position of transverse rod 7 at the top of bottom plate 5 is adjusted. By adjusting the position of multiple transverse rods 7, multiple transverse rods 7 are always pressed against the sides of multiple gas tanks. The position of multiple transverse rods 7 can limit the gas tanks of various sizes to be arranged in an array and placed on the top of support plate 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
