Description

Technical Field

[0001] The invention relates to the technical field of vacuum pump mounting seats, and in particular to a stable mounting seat for a rotary vane vacuum pump. Background Art

[0002] The rotary vane vacuum pump is one of the most basic vacuum obtaining equipment in vacuum technology and is widely used in production and scientific research departments such as electronics, chemicals and medicine. The pump body of the rotary vane vacuum pump needs to be installed and fixed through a mounting base to ensure stable and efficient operation of the rotary vane vacuum pump.

[0003] However, the existing mounting base for the rotary vane vacuum pump has fixed specifications, and the angle and height of the mounting platform cannot be adjusted, resulting in the horizontal state and height of the pump body when it is installed and used through the mounting base being completely dependent on the setting state of the base connecting component. The mounting base cannot be used to autonomously adjust the use state of the pump body after installation, resulting in poor flexibility and low practicality. Summary of the invention

[0004] In view of this, the present invention provides a stable mounting base for a rotary vane vacuum pump, which has a support assembly. The coordinated use of three groups of support assemblies can realize the regulation of the horizontal state and the use height of the mounting platform. The platform assembly can be adapted to be installed and used on different base connecting components, and the function of adjusting the use state of the pump body on the top of the mounting platform can be realized through the support assembly. The use is flexible, and the support assembly has a self-locking function, so that factors such as vibration generated by the pump body during operation will not affect the support assembly. The support assembly will not accidentally change the use state of the mounting platform when the pump body is working. The flexibility, adaptability and stability are extremely strong.

[0005] The present invention provides a stable mounting base for a rotary vane vacuum pump, specifically comprising a platform assembly, wherein the platform assembly comprises a bottom positioning plate, wherein the bottom positioning plate is fixedly mounted on the ground at the installation position of the rotary vane vacuum pump; and further comprising a support assembly, wherein the platform assembly further comprises a mounting platform; the support assembly comprises a support column, a positioning support rod, an adjustment seat, a synchronous sprocket and a control seat, wherein the bottom of the support column is fixedly mounted on the top of the bottom positioning plate, and the positioning support rod is inserted into the interior of the support column, the top of the positioning support rod is rotatably connected to the bottom of the mounting platform via a connecting ball, the adjustment seat is rotatably connected to the top of the support column, and the synchronous sprocket is rotatably connected to the outside of the adjustment seat, and the control seat is inserted into the outside of the support column.

[0006] Furthermore, a track block is provided inside the supporting column, and a track groove is provided inside the positioning supporting rod, and the track block is inserted into the track groove.

[0007] Furthermore, the rod body of the positioning support rod is provided with threads on the outside, and the positioning support rod is screwed to the inside of the adjustment seat through the rod body threads.

[0008] Furthermore, the support components are provided in three groups, and the three groups of support components are installed in a ring array inside the platform component, and the synchronous sprocket wheels of the three groups of support components are connected by chain transmission.

[0009] Furthermore, a synchronous top spring is provided at the bottom of the control seat, and two ends of the synchronous top spring are respectively against the bottom of the control seat and the outside of the supporting column.

[0010] Furthermore, the adjustment seat and the synchronous sprocket are provided with synchronous tooth grooves on the opposite side, and the top of the control seat is provided with a synchronous gear. Under the action of the synchronous top spring, when the control seat is not affected by external force, the synchronous gear is simultaneously inserted into the synchronous tooth grooves of the adjustment seat and the synchronous sprocket.

[0011] Furthermore, a locking seat is inserted at the bottom of the supporting column of one group of the supporting assemblies, and a limiting groove is provided inside the locking seat, and a limiting block is provided outside the supporting column, and the limiting groove is inserted inside the limiting block.

[0012] Furthermore, a locking top spring is provided at the bottom of the locking seat, and two ends of the locking top spring respectively abut against the bottom of the locking seat and the bottom of the supporting column.

[0013] Furthermore, a locking tooth groove is provided at the top of the locking seat, and a locking gear is provided at the bottom of the control seat on which the supporting assembly of the locking seat is installed. Under the action of the locking top spring, when the locking seat is not subjected to external force, the locking tooth groove is inserted into the outside of the locking gear.

[0014] The present invention provides a stable mounting seat for a rotary vane vacuum pump, which has the following beneficial effects.

[0015] 1. The coordinated use of the three groups of support components can realize the regulation of the horizontal state and the use height of the installation platform. The platform components can be installed and used on different base connection components, and the support components can realize the function of adjusting the use state of the pump body on the top of the installation platform. It is flexible to use and highly adaptable.

[0016] 2. The support assembly has a self-locking function, so that factors such as the vibration generated by the pump body during operation will not affect the support assembly. The support assembly will not accidentally change the use status of the installation platform when the pump body is working, and it has extremely strong stability.

[0017] 3. The support assembly can realize the function of adjusting the use status (height, levelness, etc.) of the installation platform, and can be adapted to installation and use on different ground connecting components. When it is necessary to adjust the use height of the installation platform, it is only necessary to rotate the adjustment seat of any group of support assemblies to adjust the use height of the installation platform. When rotating any one of the adjustment seats, the adjustment seats of the three groups of support assemblies can rotate synchronously, so that the three positioning support rods can be lifted and lowered synchronously to change the effective support height, that is, the use height of the installation platform is changed. When it is necessary to adjust the levelness of the installation platform, the support angle of the installation platform can be changed when the effective support height of the positioning support rod of a certain support assembly is adjusted separately. When it is necessary to adjust a certain support assembly separately, it is only necessary to pull down the control seat of the group of support assemblies and then rotate the adjustment seat to realize the effective support height of the positioning support rod of the group of support assemblies separately. After that, when the adjustment seat is rotated, the adjustment seat can only rotate separately and will not drive the adjustment seats of other support assemblies to rotate, thereby realizing the function of separately adjusting the effective support height of the positioning support rod of a certain support assembly. The adjustment is convenient and fast, and can adapt to different installation and use requirements.

[0018] 4. The support assembly has a self-locking function. The locking top spring can lift the locking seat to lock the support assembly. When the locking seat is lifted, the locking tooth groove is plugged into the outside of the locking gear. At this time, the adjustment seat, the synchronous sprocket and the control seat of the support assembly cannot rotate as a whole. Therefore, under the cooperation of the chain and the three synchronous sprockets, the overall locking operation of the three support assemblies can be achieved. When it is necessary to adjust the use height of the mounting platform, it is only necessary to pull down the locking seat to release the plug-in locking relationship between the locking tooth groove and the locking gear. The adjustment seats of the three support assemblies can be unlocked and rotated freely, thereby realizing the function of adjusting the use height of the mounting platform. When adjusting the horizontal state of the mounting platform, it is not necessary to unlock the support assembly by pulling down the locking seat. It is only necessary to pull down the control seat of the corresponding support assembly to release the overall relationship between the adjustment seat and the synchronous sprocket. The adjustment seat can rotate independently of the locking seat and the synchronous sprocket, thereby realizing the function of adjusting the horizontal state of the mounting platform, thereby improving the stability of the device.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention.

[0034] Please refer to Figures 1 to 9 As shown:

[0035] Embodiment 1: The present invention provides a stable mounting base for a rotary vane vacuum pump, including a platform assembly 1, wherein the platform assembly 1 includes a bottom positioning plate 101, and the bottom positioning plate 101 is fixedly mounted on the ground at the installation position of the rotary vane vacuum pump; it also includes a support assembly 2, and the platform assembly 1 also includes a mounting platform 102; the support assembly 2 includes a support column 201, a positioning support rod 202, an adjustment seat 203, a synchronous sprocket 204 and a control seat 205, the bottom of the support column 201 is fixedly mounted on the top of the bottom positioning plate 101, and the positioning support rod 202 is inserted into the inside of the support column 201, the top of the positioning support rod 202 is rotatably connected to the bottom of the mounting platform 102 through a connecting ball, the adjustment seat 203 is rotatably connected to the top of the support column 201, and the synchronous sprocket 204 is rotatably connected to the outside of the adjustment seat 203, the control seat 205 is inserted into the outside of the support column 201, and the rotary vane vacuum pump is fixedly mounted on the top of the mounting platform 102.

[0036] Among them, a track block 2011 is provided inside the support column 201, and a track groove 2021 is provided inside the positioning support rod 202. The track block 2011 is inserted into the track groove 2021. The track block 2011 can limit the moving trajectory of the positioning support rod 202 inside the support column 201 through the track groove 2021, so that the positioning support rod 202 will not be skewed, twisted, or rotated during movement, which will cause the support component 2 to fail in its regulating function, and the use is stable.

[0037] Among them, the outside of the rod body of the positioning support rod 202 is provided with a thread, and the positioning support rod 202 is screwed to the inside of the adjustment seat 203 through the rod body thread. By rotating the adjustment seat 203, the effective support height of the positioning support rod 202 can be adjusted, thereby realizing the function of adjusting the use status (height, levelness, etc.) of the installation platform 102, and can adapt to installation and use on different ground connection components.

[0038] Among them, there are three groups of support components 2, and the three groups of support components 2 are installed in a circular array inside the platform component 1. The synchronous sprockets 204 of the three groups of support components 2 are connected by chain transmission. The setting of the three groups of support components 2 realizes the function of adjusting the height and levelness of the installation platform 102, and the two adjustment methods are independent of each other and do not interfere with each other during adjustment, which is convenient for adjustment.

[0039] Among them, a synchronous top spring 2052 is provided at the bottom of the control seat 205, and the two ends of the synchronous top spring 2052 are respectively against the bottom of the control seat 205 and the outside of the support column 201, the adjustment seat 203 and the synchronous sprocket 204 are provided with synchronous tooth grooves 2031 on the opposite sides, and a synchronous gear 2051 is provided at the top of the control seat 205. Under the action of the synchronous top spring 2052, when the control seat 205 is not affected by external force, the synchronous gear 2051 is simultaneously inserted into the synchronous tooth grooves 2031 of the adjustment seat 203 and the synchronous sprocket 204.

[0040] Specific usage and function of this embodiment: In the present invention, after the bottom positioning plate 101 is installed on the ground connection component, the use state of the mounting platform 102 is adjusted according to the actual situation. When the use height of the mounting platform 102 needs to be adjusted, the use height of the mounting platform 102 can be adjusted by rotating the adjustment seat 203 of any group of support components 2. When any adjustment seat 203 is rotated, the adjustment seat 203 can drive the positioning support rod 202 to move up and down inside the support column 201 through the rod body thread of the positioning support rod 202 to change the effective support height. At the same time, the synchronous top spring 20 52, the control seat 205 is not subjected to external force. The synchronous gear 2051 is simultaneously inserted into the synchronous tooth groove 2031 of the adjustment seat 203 and the synchronous sprocket 204, so that the adjustment seat 203, the synchronous sprocket 204 and the control seat 205 form a whole. Therefore, under the cooperation of the chain and the synchronous sprocket 204 of the three groups of support components 2, when any one of the adjustment seats 203 is rotated, the adjustment seats 203 of the three groups of support components 2 can rotate synchronously, so that the three positioning support rods 202 can be raised and lowered synchronously to change the effective support height, that is, the use height of the installation platform 102 is changed.

[0041] When it is necessary to adjust the levelness of the installation platform 102, the effective support height of the positioning support rod 202 of a certain support component 2 can be adjusted individually to change the support angle of the installation platform 102, so that the levelness of the installation platform 102 can be adjusted and used by adjusting the effective support height of the positioning support rod 202 of the required support component 2 individually according to actual conditions. When it is necessary to adjust a certain support component 2 individually, it is only necessary to pull down the control seat 205 of the group of support components 2 and then rotate the adjustment seat 203 to achieve the effective support height of the positioning support rod 202 of the group of support components 2 individually. After the control seat 205 is pulled down, the synchronous gear 2051 will escape from the interior of the synchronous tooth groove 2031 of the adjustment seat 203, thereby releasing the overall state between the adjustment seat 203 and the synchronous sprocket 204, so that when the adjustment seat 203 is rotated thereafter, the adjustment seat 203 can only rotate alone and will not drive the adjustment seats 203 of other support components 2 to rotate, thereby realizing the function of adjusting the effective support height of the positioning support rod 202 of a certain support component 2 alone, and after the adjustment is completed and the control seat 205 is released, under the action of the synchronous top spring 2052, the control seat 205 can automatically move up and reset to restore the overall relationship between the adjustment seat 203, the synchronous sprocket 204 and the control seat 205;

[0042] After the use height and horizontal state of the installation platform 102 are adjusted, the pump body can be installed on the top of the installation platform 102 .

[0043] Embodiment 2: On the basis of embodiment 1, a locking seat 3 is inserted at the bottom of the supporting column 201 of one group of supporting assemblies 2, and a limiting groove 301 is provided inside the locking seat 3, and a limiting block 2012 is provided outside the supporting column 201, and the limiting groove 301 is inserted inside the limiting block 2012. This design makes it impossible for the locking seat 3 to rotate outside the supporting column 201, thereby realizing the function of locking the supporting assembly 2, avoiding the phenomenon that the effective supporting height of the positioning support rod 202 is accidentally changed due to factors such as vibration generated by the pump body during use, and the use is stable.

[0044] Among them, a locking top spring 303 is provided at the bottom of the locking seat 3, and the two ends of the locking top spring 303 respectively abut against the bottom of the locking seat 3 and the bottom of the supporting column 201, a locking tooth groove 302 is provided at the top of the locking seat 3, and a locking gear 2053 is provided at the bottom of the control seat 205 of the supporting assembly 2 on which the locking seat 3 is installed. Under the action of the locking top spring 303, when the locking seat 3 is not subjected to external force, the locking tooth groove 302 is inserted into the outside of the locking gear 2053.

[0045] Specific usage and function of this embodiment: In the present invention, the locking top spring 303 can lift the locking seat 3 in the reset state (when the locking seat 3 is not pulled by external force) to lock the support assembly 2. When the locking seat 3 is lifted up, the locking tooth groove 302 is plugged into the outside of the locking gear 2053, so that the adjustment seat 203, the synchronous sprocket 204 and the control seat 205 of the group of support assemblies 2 cannot rotate as a whole. Therefore, under the cooperation of the chain and the three synchronous sprockets 204, the overall locking operation of the three groups of support assemblies 2 can be achieved. When it is necessary to adjust the use height of the mounting platform 102, it is only necessary to pull the locking seat 3 downward to release the plug-in locking relationship between the locking tooth groove 302 and the locking gear 2053. The adjustment seats 203 of the support components 2 can be unlocked and rotated freely, thereby realizing the function of adjusting the use height of the installation platform 102. After the adjustment is completed, the locking seat 3 is released and the locking seat 3 can be automatically reset to restore the locking state of the support component 2 under the action of the locking top spring 303. At the same time, when adjusting the horizontal state of the installation platform 102, there is no need to unlock the support component 2 by pulling down the locking seat 3. When it is necessary to rotate the adjustment seat 203 of a certain support component 2 separately, after the overall relationship between the adjustment seat 203 and the synchronous sprocket 204 is released by pulling down the control seat 205, the adjustment seat 203 can independently rotate with the locking seat 3 and the synchronous sprocket 204, thereby realizing the function of adjusting the horizontal state of the installation platform 102, which is convenient for regulation.

[0046] In another embodiment, a rubber buffer pad is provided on the top of the mounting platform 102, which can provide a certain buffering effect for the pump body when working, thereby improving the durability of the pump body.
