Description

Technical Field

[0001] The present application relates to the technical field of rubber tube installation, and in particular to an L-shaped rubber tube joint locking fixture. Background Art

[0002] The compressor sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it through the operation of the motor to drive the piston, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. In order to ensure the operation of the compressor, the compressor is connected to an oil inlet pipe through an L-shaped rubber pipe joint. The oil inlet pipe transports the lubricating oil from the oil pool to various lubrication parts of the compressor, providing lubrication for various moving parts of the compressor, reducing wear and tear, and ensuring the normal operation of the compressor.

[0003] Reference Figure 1 The L-shaped rubber tube joint includes a joint body 01, which is L-shaped. Both ends of the L-shaped joint body 01 are provided with threaded joints 02. The compressor is provided with a threaded interface matching the threaded joint 02. When producing the compressor, the threaded joint 02 needs to be threadedly connected to the threaded interface so that it can be connected to the oil inlet pipe when the compressor is working. The usual installation method requires workers to tighten the rubber tube joint manually or with a wrench. When a large number of compressors need to be installed, a lot of installation time is required. The installation efficiency of the rubber tube joint is low, which has obvious shortcomings. Utility Model Content

[0004] In order to improve the installation efficiency of the rubber pipe joint, the present application provides an L-shaped rubber pipe joint locking fixture.

[0005] The present application provides an L-shaped rubber pipe joint locking fixture adopts the following technical solution:

[0006] An L-shaped rubber pipe joint locking fixture comprises a mounting block, wherein the mounting block is provided with a mounting groove for mounting the L-shaped rubber pipe joint, a sleeve is provided on the bottom surface of the mounting block, and a driving member for driving the mounting block to rotate is provided in the sleeve.

[0007] By adopting the above technical solution, when installation is required, the worker places the rubber tube joint in the installation groove, and then starts the driving member, the driving member drives the sleeve to rotate, the sleeve drives the installation block to rotate, and the installation block drives the rubber tube joint to rotate, and the installation of the rubber tube joint is realized during the rotation process. This installation process realizes the rapid installation of the rubber tube joint through the driving member. When installing a large number of compressors, the installation time consumed is shortened compared to manual installation, thereby improving the installation efficiency of the rubber tube joint.

[0008] Optionally, the driving member is a pneumatic screwdriver, and the bit of the pneumatic screwdriver is connected to the sleeve.

[0009] By adopting the above technical solution, the pneumatic screwdriver drives the motor through compressed air, thereby driving the cutter head to rotate, and the rotation of the cutter head drives the rubber tube joint to be screwed into the interface of the compressor. The pneumatic screwdriver is small in size and light in weight, which is convenient for workers to carry. Workers can flexibly install interfaces in various positions, thereby improving the flexibility of the installation of the rubber tube joint.

[0010] Optionally, a clamping groove is provided on the bottom surface of the sleeve, and the bit of the pneumatic screwdriver is clamped in the clamping groove.

[0011] By adopting the above technical solution, the provision of the clamping groove makes it convenient for workers to disassemble the pneumatic screwdriver, so that workers can replace pneumatic screwdrivers of different specifications according to installation blocks of different specifications, which is convenient for workers to operate.

[0012] Optionally, a clamping assembly is provided in the mounting groove, and the clamping assembly includes a gear rotatably connected to the inner side wall of the mounting groove, one end of the gear is meshed with an upper rack plate, and the other opposite end is meshed with a lower rack plate, the upper rack plate and the lower rack plate are both slidably connected to the inner side wall of the mounting groove, and clamping plates are provided at both ends of the upper rack plate and the lower rack plate that are away from each other, and the two clamping plates are slidably set in the mounting groove.

[0013] By adopting the above technical solution, after the worker puts the rubber tube joint into the installation groove, the gear is rotated. The rotation of the gear drives the meshing upper rack plate and the lower rack plate to move in opposite directions, so that the two clamping plates are close to each other. When both clamping plates are in contact with the rubber tube joint, the gear is stopped and the rubber tube joint is fixed in the installation groove. The stability of the rubber tube joint during the installation process is improved by the clamping assembly, and the clamping of rubber tube joints of different specifications and sizes is also realized.

[0014] Optionally, an upper guide rod and a lower guide rod are provided at opposite ends of the mounting groove, the upper rack plate is slidably connected to the upper guide rod, the lower rack plate is slidably connected to the lower guide rod, both ends of the upper guide rod and the lower guide rod are commonly connected with a connecting block, one end of the connecting block is slidably connected to the upper guide rod, and the other end is slidably connected to the lower guide rod, and the surface of the connecting block is connected to the surface of the clamping plate.

[0015] By adopting the above technical solution, under the guiding action of the upper guide rod and the lower guide rod, the upper rack plate and the lower rack plate can only move along a fixed direction. At the same time, the setting of the connecting block reduces the friction force of the clamping plate sliding in the installation groove, making the clamping process of the clamping plate smoother.

[0016] Optionally, a mounting cylinder is provided on the outer surface of the mounting block, and a driving component for driving the gear to rotate is provided in the mounting cylinder, the driving component includes a rotating shaft rotatably provided in the mounting cylinder, an external gear is fixedly connected to the rotating shaft, the external gear is rotatably provided inside the mounting cylinder, one end of the rotating shaft is coaxially fixedly connected to the gear, and the other end is fixedly connected to a handwheel, and a locking component for limiting the rotation of the external gear is provided in the mounting cylinder.

[0017] By adopting the above technical solution, when it is necessary to clamp the rubber pipe joint, the worker turns the hand wheel, the rotation of the hand wheel drives the rotating shaft to rotate, the rotation of the rotating shaft drives the gear to rotate, so that the clamping assembly clamps the workpiece, and when the clamping is completed, the rotation of the outer gear is limited by the locking assembly, the outer gear cannot rotate, the rotating shaft cannot rotate, and the gear cannot rotate, the upper rack plate and the lower rack plate cannot move, and the clamping plate is fixed, avoiding the phenomenon that the clamping plate is separated from the rubber pipe joint due to the worker accidentally touching the hand wheel, thereby further improving the stability of the clamping assembly after clamping.

[0018] Optionally, the locking assembly includes an inner gear ring slidably arranged in the mounting cylinder, sliders are provided at opposite ends of the inner gear ring, a sliding groove slidably matched with the slider is opened on the mounting cylinder, a plurality of springs are arranged in the mounting cylinder, one end of the spring is connected to the inner gear ring, and the other end is connected to the outer wall of the mounting block, when the spring is in a natural state, the inner gear ring is meshed with the external gear, and a pull ring is provided on a side of the inner gear ring away from the mounting block.

[0019] By adopting the above technical solution, when clamping is required, the worker pulls the pull ring outward to make the inner gear ring disengage from the outer gear, and the rotating shaft can be rotated at this time. When the clamping is completed, the worker releases the pull ring, and the spring reset drives the inner gear ring to re-engage with the outer gear. Under the restriction of the slider and the slide groove, the inner gear ring cannot be rotated, so that the outer gear cannot be rotated, and at the same time, the gear coaxially fixed to the outer gear cannot be rotated, thereby achieving the locking of the gear.

[0020] Optionally, rubber pads are provided on the opposite surfaces of the two clamping plates.

[0021] By adopting the above technical solution, the provision of the rubber pad reduces the extrusion force of the rubber pipe joint from the extrusion plate, thereby reducing the possibility of the rubber pipe joint being damaged.

[0023] 1. The present application provides a mounting block, a sleeve and a driving member, wherein the driving member drives the sleeve to rotate, the sleeve drives the mounting block to rotate, and the mounting block drives the rubber tube joint to rotate, so that the rubber tube joint is installed during the rotation process.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The embodiment of the present application discloses an L-shaped rubber pipe joint locking fixture.

[0034] Reference Figure 2 and Figure 3 An L-shaped rubber pipe joint locking fixture includes a mounting block 1, a mounting groove 2 for mounting the L-shaped rubber pipe joint is opened on the mounting block 1, a sleeve 3 is fixedly installed on the bottom surface of the mounting block 1, a vertically arranged clamping groove 31 is opened on the bottom surface of the sleeve 3, and a driving member 4 is arranged in the clamping groove 31. Specifically, the driving member 4 is a pneumatic screwdriver 41, and the blade of the pneumatic screwdriver 41 is clamped in the clamping groove 31.

[0035] When installation is required, the worker places the rubber tube joint in the installation groove 2, and then starts the pneumatic screwdriver 41. The pneumatic screwdriver 41 drives the sleeve 3 to rotate, the sleeve 3 drives the installation block 1 to rotate, and the installation block 1 drives the rubber tube joint to rotate. The installation of the rubber tube joint is achieved during the rotation process. The installation process uses the pneumatic screwdriver 41 to achieve rapid installation of the rubber tube joint. At the same time, the pneumatic screwdriver 41 is small in size and light in weight, so it is convenient for workers to carry it. When installing a large number of compressors, workers can flexibly install the threaded interfaces of each compressor. Compared with manual installation, the installation time is shortened, thereby improving the installation efficiency of the rubber tube joint.

[0036] The arrangement of the clamping slot 31 facilitates workers to disassemble the pneumatic screwdriver 41, so that workers can replace pneumatic screwdrivers 41 of different specifications according to the installation blocks 1 of different specifications, which is convenient for workers to operate.

[0037] Reference Figure 4 A clamping assembly 5 for clamping a rubber pipe joint is arranged in the installation groove 2. Specifically, the clamping assembly 5 includes a gear 51 rotatably connected to the inner wall of the installation groove 2. An upper rack plate 52 is meshed at one end of the gear 51, and a lower rack plate 53 is meshed at the other end thereof. An upper guide rod 6 and a lower guide rod 7 are fixedly installed on the inner wall of the installation groove 2. The upper guide rod 6 and the lower guide rod 7 are both horizontally arranged and distributed at both ends of the installation groove 2. The upper rack plate 52 is slidably connected to the upper guide rod 6, and the lower rack plate 53 is meshed at the other end thereof. The strip plate 53 is slidably connected to the lower guide rod 7, and one end of the upper rack plate 52 and the lower rack plate 53 close to the inner wall of the mounting groove 2 are fixedly connected to a connecting block 8, one end of the connecting block 8 is slidably connected to the upper guide rod 6, and the other end is slidably connected to the lower guide rod 7. A clamping plate 54 is fixedly installed on the surface of each connecting block 8, and the clamping plate 54 extends along the length direction of the mounting block 1. The clamping plate 54 is slidably set inside the mounting groove 2, and rubber pads 9 are installed on the surfaces of the two clamping plates 54 close to the rubber pipe joint.

[0038] After the worker puts the rubber tube joint into the installation groove 2, he rotates the gear 51. The rotation of the gear 51 drives the meshing upper rack plate 52 and the lower rack plate 53 to move in a direction close to each other, so that the two clamping plates 54 are close to each other. When the rubber pads 9 on the two clamping plates 54 are in contact with the rubber tube joint, the rotation of the gear 51 is stopped, and the rubber tube joint is fixed in the installation groove 2 by the two clamping plates 54. The stability of the rubber tube joint during the installation process is improved by the clamping assembly 5, and the clamping of rubber tube joints of different specifications and sizes is also achieved. When clamping rubber tube joints of different specifications, the worker does not need to replace the installation blocks 1 of different specifications, thereby further improving the installation efficiency of the rubber tube joint. At the same time, the setting of the rubber pad 9 reduces the extrusion force of the rubber tube joint from the extrusion plate, reducing the possibility of damage to the rubber tube joint.

[0039] Reference Figure 4 and Figure 5 A mounting cylinder 10 is fixedly mounted on the surface of the mounting block 1 facing away from the mounting groove 2, and a driving component 11 for driving the gear 51 to rotate is arranged in the mounting cylinder 10. Specifically, the driving component 11 includes a rotating shaft 111 rotatably arranged in the mounting cylinder 10, and an external gear 112 is fixedly connected to the rotating shaft 111. The external gear 112 is rotatably arranged inside the mounting cylinder 10. One end of the rotating shaft 111 extends into the mounting groove 2 and is coaxially fixedly connected to the gear 51, and the other end extends out of the mounting cylinder 10 and is fixedly connected to a handwheel 113.

[0040] A locking assembly 12 for limiting the rotation of the external gear 112 is provided in the mounting cylinder 10. Specifically, the locking assembly 12 includes an inner gear ring 121, which is slidably connected in the mounting cylinder 10. Slide blocks 122 are provided at opposite ends of the inner gear ring 121. A slide groove 101 slidably matched with the slide block 122 is provided on the opposite inner walls of the mounting cylinder 10. The slide groove 101 is arranged along the length direction of the mounting cylinder 10. Two springs 123 are symmetrically arranged about the rotating shaft 111 in the mounting cylinder 10. One end of each spring 123 is fixedly connected to one end of the inner gear ring 121, and the other end is fixedly connected to the outer wall of the mounting block 1. When the spring 123 is in a natural state, the inner gear ring 121 is meshed with the external gear 112, and a pull ring 124 is provided on the side of the inner gear ring 121 away from the spring 123.

[0041] When the rubber pipe joint needs to be clamped, the worker pulls the pull ring 124 outward to disengage the inner gear ring 121 from the outer gear 112, and then the worker rotates the hand wheel 113, the rotation of the hand wheel 113 drives the rotating shaft 111 to rotate, and the rotation of the rotating shaft 111 drives the gear 51 to rotate, so that the clamping assembly 5 clamps the workpiece. When the clamping is completed, the worker releases the pull ring 124, the spring 123 resets and drives the inner gear ring 121 to move toward the direction close to the spring 123, and the inner gear ring 121 meshes with the outer gear 112, and at the same time, the slider 1 22 and the slide groove 101, the rotation of the inner gear ring 121 is restricted so that the outer gear 112 cannot be rotated, and the rotating shaft 111 fixedly connected to the outer gear 112 cannot be rotated, so that the gear 51 cannot be rotated. The gear 51 cannot rotate so that the upper rack plate 52 and the lower rack plate 53 cannot move, and the clamping plate 54 is fixed, avoiding the occurrence of the clamping plate 54 detaching from the rubber pipe joint due to the worker accidentally touching the hand wheel 113, thereby further improving the stability of the clamping assembly 5 after clamping.

[0042] The implementation principle of an L-shaped rubber tube joint locking fixture in an embodiment of the present application is as follows: first, a worker places the rubber tube joint into the installation groove 2, and then the worker pulls the pull ring 124 outward to disengage the inner gear ring 121 from the outer gear 112, and turns the hand wheel 113. The hand wheel 113 drives the clamping assembly 5 to clamp the rubber tube joint. After clamping, the pull ring 124 is released to engage the inner gear ring 121 with the outer gear 112, and the gear 51 cannot be rotated. Finally, the worker starts the pneumatic screwdriver 41, and the pneumatic screwdriver 41 drives the sleeve 3 to rotate, and the sleeve 3 drives the installation block 1 to rotate, and the installation block 1 drives the rubber tube joint to rotate. The installation of the rubber tube joint is realized during the rotation process. The installation process realizes the rapid installation of the rubber tube joint through the pneumatic screwdriver 41, and the installation time consumed is shortened compared to manual installation, thereby improving the installation efficiency of the rubber tube joint.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
