Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer which is easy to disassemble. Background Art

[0002] Reducers play an optimization role in mechanical structure design. Using reducers can reduce the power requirements of the motor, thereby simplifying the entire product design structure. This allows functional components to be designed to be more refined and compact, avoiding the product from looking "dumb and clumsy". This optimization not only reduces material and manufacturing costs, but also improves the overall performance and appearance of the product. Therefore, mechanical design engineers tend to choose to use reducers.

[0003] The existing reducer has the following problems:

[0004] 1. When repairing the reducer, the cover is not easy to remove quickly for maintenance, which is a waste of time.

[0005] 2. After the cover is removed for maintenance, it cannot be quickly positioned during installation. Utility Model Content

[0006] The purpose of the utility model is to provide a speed reducer that is easy to disassemble, so as to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A reducer that is easy to disassemble comprises a reducer body, the upper surface of which is provided with a mounting hole, a cover plate fixedly connected to the front of the reducer body, a mounting buckle provided on the front of the cover plate, and a positioning buckle provided on the side of the reducer body.

[0009] The mounting buckle comprises a mounting shell fixedly connected to the inside of the cover plate, a protrusion is fixedly connected to the inner wall of the mounting shell, and a fixing cylinder is fixedly connected to the inside of the mounting shell.

[0010] A further improvement of the technical solution of the utility model is that: a sliding rod is slidably connected inside the fixing tube, and a tightening spring piece is fixedly connected to the other end of the sliding rod.

[0011] A further improvement of the technical solution of the utility model is that a spring is sleeved on the surface of the fixing tube, the two ends of the spring are respectively fixedly connected to the mounting shell and the tightening spring sheet, the side of the tightening spring sheet is fixedly connected to a spring sheet boss, and the convex block and the spring sheet boss are adapted to each other.

[0012] A further improvement of the technical solution of the utility model is that: a pressing rod is fixedly connected to the upper surface of the tightening spring sheet, and a disassembly hole is fixedly connected to the upper surface of the mounting shell.

[0013] A further improvement of the technical solution of the utility model is that the positioning buckle comprises a positioning shell fixedly connected to the side of the reducer body, and a positioning rod is movably connected inside the positioning shell.

[0014] A further improvement of the technical solution of the utility model is that a baffle is fixedly connected to the surface of the positioning rod and located inside the positioning shell, and a positioning spring is sleeved on the surface of the positioning rod.

[0015] A further improvement of the technical solution of the utility model is that the two ends of the positioning spring are fixedly connected to the baffle and the positioning shell respectively, and one end of the positioning rod extends to the outside of the positioning shell and is fixedly connected with a pull head.

[0016] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0017] 1. The utility model provides a speed reducer which is easy to disassemble. The speed reducer is installed in a suitable position through the installation hole by matching the installation buckle, sliding rod, spring, pressing rod, tightening spring piece and disassembly hole. When the interior of the speed reducer body is damaged or lubrication maintenance is required, the cover plate needs to be removed. The user only needs to put his finger into the disassembly hole and press the pressing rod downward. The downward movement of the pressing rod drives the tightening spring piece and the sliding rod to move downward together. The downward movement of the tightening spring piece will compress the spring. At the same time, the downward movement of the tightening spring piece will drive the spring piece boss to move downward together. When the spring piece boss moves downward, it will slide relative to the protrusion. The contact between the protrusion and the spring piece boss will make the buckle outside the tightening spring piece retract into the installation shell. At this time, the installation buckle can be pulled upward to remove the installation buckle from the inside of the cover plate, so that the cover plate can be removed.

[0018] 2. The utility model provides a speed reducer which is easy to disassemble. It cooperates with a positioning buckle, a positioning rod, a pull head, a positioning spring and a baffle. When the cover needs to be disassembled, the installation buckle is removed and the cover is slid downward. A positioning hole is opened on the side of the cover. When the cover slides downward, the inclined surface on the surface of the positioning rod pushes the positioning rod to slide inside the positioning shell, and the positioning rod will pop out from the positioning hole, so that the cover can be directly disassembled. When installing the cover, the cover needs to be installed and positioned. The cover is slid upward and the pull head is pulled outward. The outward movement of the pull head will drive the positioning rod and the baffle to move outward together. The positioning spring will be compressed during the outward movement of the baffle. When the cover slides to a suitable position, the pull head is released, and the positioning spring is reset to fix the positioning rod to the positioning hole, thereby completing the positioning of the cover.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the embodiments:

[0026] Example 1

[0027] like Figure 1-5 The utility model provides a reducer that is easy to disassemble, including a reducer body 1, an upper surface of the reducer body 1 is provided with a mounting hole 2, a cover plate 5 is fixedly connected to the front of the reducer body 1, a mounting buckle 3 is provided on the front of the cover plate 5, a positioning buckle 4 is provided on the side of the reducer body 1, the mounting buckle 3 includes a mounting shell 31 fixedly connected to the inside of the cover plate 5, a protrusion 32 is fixedly connected to the inner wall of the mounting shell 31, a fixing cylinder 33 is fixedly connected to the inside of the mounting shell 31, a sliding rod 34 is slidably connected to the inside of the fixing cylinder 33, and a fixing spring 37 is fixedly connected to the other end of the sliding rod 34, a spring 35 is sleeved on the surface of the fixing cylinder 33, two ends of the spring 35 are respectively fixedly connected to the mounting shell 31 and the fixing spring 37, a spring boss 38 is fixedly connected to the side of the fixing spring 37, the protrusion 32 and the spring boss 38 are adapted, a pressing rod 36 is fixedly connected to the upper surface of the fixing spring 37, and a disassembly hole 39 is fixedly connected to the upper surface of the mounting shell 31.

[0028] In this embodiment, the reducer is installed in a suitable position through the mounting hole 2 for operation. The mounting hole 2 is set at the top of the reducer, which is convenient for maintaining the reducer from the side and keeping the force on the top of the reducer uniform to improve stability. When the interior of the reducer body 1 is damaged or lubrication maintenance is required, the cover plate 5 needs to be removed. It is only necessary to extend a finger into the disassembly hole 39 and press the pressing rod 36 downward. The pressing rod 36 moves downward to drive the tightening spring piece 37 and the sliding rod 34 to move downward together. The tightening spring piece 37 moves downward to compress the spring 35. At the same time, the tightening spring piece 37 moves downward to drive the spring piece boss 38 to move downward together. When the spring piece boss 38 moves downward, it will slide relative to the protrusion 32. The contact between the protrusion 32 and the spring piece boss 38 will cause the buckle outside the tightening spring piece 37 to be retracted into the mounting shell 31. At this time, the mounting buckle 3 can be pulled upward to remove the mounting buckle 3 from the inside of the cover plate 5, so that the cover plate 5 can be removed, thereby improving the convenience of the device.

[0029] Example 2

[0030] like Figure 1-5 It is shown that, based on Example 1, the utility model provides a technical solution: preferably, the positioning buckle 4 includes a positioning shell 41 fixedly connected to the side of the reducer body 1, and the interior of the positioning shell 41 is movably connected with a positioning rod 43.

[0031] In this embodiment, when the cover 5 needs to be disassembled, after removing the mounting buckle 3, the cover 5 is slid downward. A positioning hole is opened on the side of the cover 5. When the cover 5 slides downward, the inclined surface on the surface of the positioning rod 43 will push the positioning rod 43 to slide into the inside of the positioning shell 41, and the positioning rod 43 will pop out of the positioning hole, so that the cover 5 can be directly removed, thereby improving the convenience of the device.

[0032] Example 3

[0033] like Figure 1-5 It is shown that, based on Example 1, the utility model provides a technical solution: preferably, a baffle 44 is fixedly connected to the surface of the positioning rod 43 and located inside the positioning shell 41, a positioning spring 45 is sleeved on the surface of the positioning rod 43, and the two ends of the positioning spring 45 are respectively fixedly connected to the baffle 44 and the positioning shell 41, and a pull head 42 is fixedly connected to one end of the positioning rod 43 and extends to the outside of the positioning shell 41.

[0034] In this embodiment, when installing the cover plate 5, it is necessary to install and position the cover plate 5, slide the cover plate 5 upward, pull the pull head 42 outward, and the outward movement of the pull head 42 will drive the positioning rod 43 and the baffle 44 to move outward together. The positioning spring 45 will be compressed during the outward movement of the baffle 44. When the cover plate 5 slides to the appropriate position, release the pull head 42, and the positioning spring 45 will reset to fix the positioning rod 43 to the positioning hole, thereby completing the positioning of the cover plate 5 and improving the applicability of the device.

[0035] The following is a detailed description of the working principle of this easy-to-disassemble reducer.

[0036] like Figure 1-5 The reducer is installed in a suitable position through the mounting hole 2 for operation. When the interior of the reducer body 1 is damaged or needs lubrication and maintenance, the cover plate 5 needs to be removed. The finger only needs to be extended into the disassembly hole 39 and the pressing rod 36 is pressed downward. The pressing rod 36 moves downward to drive the tightening spring piece 37 and the sliding rod 34 to move downward together. The tightening spring piece 37 moves downward to compress the spring 35. At the same time, the tightening spring piece 37 moves downward to drive the spring piece boss 38 to move downward together. When the spring piece boss 38 moves downward, it will slide relative to the protrusion 32. The contact between the protrusion 32 and the spring piece boss 38 will make the buckle outside the tightening spring piece 37 retract into the installation shell 31. At this time, the installation buckle 3 can be pulled upward to remove the installation buckle 3 from the inside of the cover plate 5, so that the cover plate 5 can be removed. When the cover 5 needs to be disassembled, after removing the mounting buckle 3, the cover 5 is slid downward. A positioning hole is provided on the side of the cover 5. When the cover 5 slides downward, the inclined surface on the surface of the positioning rod 43 pushes the positioning rod 43 to slide into the inside of the positioning shell 41, and the positioning rod 43 will pop out from the positioning hole, so that the cover 5 can be directly disassembled. When installing the cover 5, it is necessary to install and position the cover 5, slide the cover 5 upward, and pull the pull head 42 outward. The outward movement of the pull head 42 will drive the positioning rod 43 and the baffle 44 to move outward together. The positioning spring 45 will be compressed during the outward movement of the baffle 44. When the cover 5 slides to the appropriate position, release the pull head 42. The positioning spring 45 will reset and fix the positioning rod 43 to the positioning hole, thereby completing the positioning of the cover 5.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
