Description

Technical Field

[0001] This utility model relates to the field of reducer housing technology, and in particular to a housing connection structure that can be quickly disassembled and assembled. Background Technology

[0002] As an important mechanical transmission device, speed reducers are widely used in various fields of industrial production, such as metallurgy, mining, hoisting and transportation, power, energy, and building materials.

[0003] Currently, most gearbox housings on the market adopt a split structure, consisting of an upper housing and a lower housing. This structure facilitates the manufacturing, installation, and maintenance of the gearbox. Existing technologies commonly use bolts and nuts to connect the upper and lower housings. For example, Chinese invention patent CN119042309A discloses a gearbox housing structure in which the upper and lower housings are fixedly connected by multiple bolts and nuts. Specifically, corresponding bolt holes are provided on the mating surfaces of the upper and lower housings. During installation, the upper and lower housings are aligned so that the bolt holes correspond one-to-one. Then, the bolts are passed through the bolt holes of the upper and lower housings in sequence, and nuts are installed on the other end of the bolts. Tightening the nuts tightly connects the upper and lower housings together.

[0004] However, this traditional bolt and nut connection method has many inconveniences in actual use, especially during the disassembly and installation of the reducer. During disassembly, each bolt must be loosened and removed one by one before the upper housing can be opened. Since the reducer housing typically requires multiple bolts to ensure connection strength and sealing, the bolt removal process is quite cumbersome, consuming a lot of time and manpower, and is also prone to problems such as bolt loss or damage during disassembly.

[0005] Similarly, when installing the upper housing, the holes need to be aligned before each bolt is passed through the upper and lower housings in sequence, and then the nuts are tightened one by one. This process also requires a lot of time and effort. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a quick-disassembly and assembly housing connection structure to solve the problem of cumbersome disassembly and assembly process of reducer housing.

[0007] A quick-assembly and disassembly box connection structure includes a first box, a second box, and multiple fasteners capable of generating clamping force. After the first box and the second box are fastened together, they are fixed to the edge of the box by multiple fasteners.

[0008] The first box body and the second box body are respectively provided with a first contour edge and a second contour edge that can abut against each other. The first contour edge and the second contour edge are respectively provided with outward opening notches. When the boxes are fastened together, the two notches overlap. The middle part of the fastener fits into the notch. The two ends of the fastener abut against the first contour edge and the second contour edge respectively. The bottom of the fastener is rotatably connected to the second contour edge.

[0009] In this invention, the fastener includes a bolt and a nut, with the shank of the bolt located inside a notch, the nut of the bolt abutting the top of the first profile edge, and the nut abutting the bottom of the second profile edge.

[0010] Furthermore, the nut has outwardly extending pivots on both sides, and the fastener is rotatably engaged at the bottom of the second contour edge via the pivots on the nut.

[0011] Furthermore, a connecting seat is provided on the bottom surface of the second contour edge and below the notch, and the nut is rotatably fitted onto the connecting seat.

[0012] Furthermore, the connecting seat is provided in two sets and symmetrically arranged on both sides below the notch. A limiting plane is provided on the opposite side between the two sets of connecting seats. A sliding groove is provided on the limiting plane. The interval length L between the two sets of limiting planes is equal to the opposite side dimension S of the nut. The nut is fitted between the two connecting seats and the rotating shafts on both sides are slidably fitted in the sliding grooves on both sides. The limiting plane abuts against the opposite side plane of the nut for limiting.

[0013] In this utility model, the connecting seat is integrally formed on the second contour edge, the slide groove extends out along the length direction of the notch to form a port, the rotating shafts on both sides of the nut are inserted into the slide groove from the port of the slide groove, and the port of the slide groove is covered and closed by a limiting block fixed on the connecting seat.

[0014] In this invention, a limiting groove is provided at the position of the notch corresponding to the top of the first contour edge, and the width K of the cut formed by the limiting groove at the opening end of the notch is less than the opposite side dimension S of the nut.

[0015] The beneficial effects of this utility model are:

[0016] This invention features first and second contoured edges with notches that abut against each other on the edges of the first and second housings. Fasteners that are rotatably connected to the second contoured edges are used for fixation. During disassembly, simply loosen the fasteners and flip them outwards to remove them from the notches. During assembly, simply flip the fasteners upwards to insert them into the notches and tighten them for fixation. This eliminates the cumbersome process of completely loosening and separating, removing, and initially tightening through the connecting holes, which is required in traditional bolt and nut connection methods. This greatly saves time and manpower for disassembling and installing the reducer housing, reduces the risk of lost or damaged bolts, and improves work efficiency. Attached Figure Description

[0027] Please see Figures 1 to 6 :

[0028] This embodiment discloses a quick-assembly and disassembly housing connection structure applied to a reducer housing. It mainly includes a first housing 1, a second housing 2, and multiple fasteners 3 that can generate clamping force. After the first housing 1 and the second housing 2 are fastened together, they are fixed to the edge of the housing by multiple fasteners 3. The first housing 1 and the second housing 2 are preferably an upper and lower structure, that is, the first housing 1 is fastened on the upper part of the second housing 2. Specifically, the lower edge of the first housing 1 and the upper edge of the second housing 2 are respectively provided with a first contour edge 11 and a second contour edge 21 that can abut against each other. The first contour edge 11 and the second contour edge 21 are also respectively provided with U-shaped notches 4 with outward openings. When the housings are fastened together, the notches 4 on the first contour edge 11 and the second contour edge 21 overlap.

[0029] At this time, the middle part of the fastener 3 is fitted into the notch 4, and the two ends of the fastener 3 abut against the top surface of the first contour edge 11 and the bottom surface of the second contour edge 21 respectively. Then the tightened fastener 3 clamps and fixes the first contour edge 11 and the second contour edge 21. When disassembling, the first box 1 can be removed simply by loosening the fastener 3 and taking it out of the notch 4.

[0030] In addition, such as Figure 6 As shown, the bottom of the fastener 3 is rotatably connected to the bottom surface of the second contour edge 21. After loosening the fastener 3, it can be directly flipped outward to exit the notch 4, eliminating the need to completely loosen and remove the bolt and nut. Conversely, during assembly, after fastening the first housing 1 and the second housing 2, the fastener 3 can be directly flipped upward to enter the notch 4, thereby tightening and fixing the fastener 3, eliminating the need to pass the bolt and nut through the connecting hole and initially tighten it.

[0031] In this embodiment, as Figure 3 As shown, the fastener 3 includes a bolt 31 and a nut 32. When the bolt 31 and the nut 32 are engaged, the shank of the bolt 31 is located in the notch 4, the nut 311 of the bolt 31 abuts against the top of the first profile edge 11, and the nut 32 abuts against the bottom of the second profile edge 21.

[0032] In addition, such as Figure 4 As shown, the nut 32 has outwardly extending shafts 321 on both sides, and the fastener 3 is rotatably fitted to the bottom of the second contour edge 21 through the shafts 321 on the nut 32.

[0033] Furthermore, such as Figure 4As shown, to facilitate the engagement of the nut 32, connecting seats 5 are respectively provided on the bottom surface of the second contour edge 21 and on both sides below the notch 4. The two sets of connecting seats 5 are symmetrically arranged, and a limiting plane 51 is provided on the opposite side between the two sets of connecting seats 5. A sliding groove 52 is also provided on the limiting plane 51. The interval length L between the two sets of limiting planes 51 is equal to the opposite side dimension S of the nut 32. The nut 32 is engaged between the two connecting seats 5, and the rotating shafts 321 on both sides are slidably engaged in the sliding grooves 52 on both sides. At the same time, the limiting plane 51 abuts against the opposite side plane of the nut 32 to limit the movement and prevent the nut 32 from rotating relative to the bolt 31.

[0034] Furthermore, such as Figure 4 As shown, the connecting seat 5 is integrally formed on the second contour edge 21. In order to facilitate the installation of the nut 32, the slide groove 52 extends out along the extension direction of the notch 4 to form a port. At this time, the rotating shafts 321 on both sides of the nut 32 can be inserted into the slide groove 52 from the port of the slide groove 52. Then, the limiting block 6 is fixed on the connecting seat 5 to cover and close the port of the slide groove 52 to prevent the nut 32 from falling out. In addition, the slide groove 52 has a certain stroke space and can slide up and down with the rotating shaft 321. When the bolt 31 needs to be rotated outward, it can provide sufficient rotation space for the nut 32.

[0035] In this embodiment, as Figure 5 As shown, the fastener 3 is easy to come out of the notch 4 when it is loose, which affects the assembly. Therefore, a limiting groove 7 is provided at the position of the notch 4 at the top of the first contour edge 11. The width K of the notch 4 opening formed by the limiting groove 7 is smaller than the opposite side dimension S of the nut 311. This structure can prevent the fastener 3 from easily coming out of the notch 4. Only when the bolt 31 is loosened to a height above the groove plane of the limiting groove 7 can the fastener 3 be flipped outward to come out of the notch 4.

[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present invention.
