Description

Technical Field

[0001] The utility model relates to the technical field of electric cylinders, in particular to an electric cylinder with good waterproof performance. Background Art

[0002] Electric cylinders are products designed for continuous motion, low to high loads, and can be used for many cycles during their service life. These products have extremely high positioning accuracy and controllability, and can achieve precise motion control under loads from several kilograms to 50 tons.

[0003] At present, electric cylinders mainly use motors and screws to drive the hollow piston rod fixed with the nut to make linear motion. The connection between the electric cylinder nut and the hollow piston rod is a single-side step structure. The motor piston rod is round and needs to be anti-rotation treated. The anti-rotation structure is complex and the load conditions need to be considered. For loads that can rotate, other structures need to be installed to prevent the piston rod from rotating. The piston rod of this structure is a hollow cylinder structure. For long-stroke electric cylinders, the accuracy and economy of linear motion are improved. The electric cylinder of this structure is mainly grease lubricated, which greatly reduces the life of the screw nut transmission. If the lubrication is not in place, the transmission part will heat up, and the screw and nut will burn out, causing the electric cylinder to fail.

[0004] In the prior art, a Chinese patent with a publication number of CN207777324U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: an electric cylinder, including an external power device, a lead screw, a nut, a push rod and a coupling disk, wherein the external power device is connected to the lead screw, the nut is sleeved on the lead screw, a push rod is fixed to the top of the nut, and the top of the push rod is connected to the coupling disk. The beneficial effect of the utility model is that due to the adoption of the above-mentioned technical solution, an electric cylinder with large thrust, high transmission strength, good guiding accuracy, impact resistance, ultra-long life, low noise, and lubricated with grease can be provided. However, there is still a problem that the motor needs ventilation and heat dissipation, which causes water to easily penetrate into the interior of the motor and affect the service life of the motor, which has certain limitations. Summary of the invention

[0005] The purpose of the utility model is to provide an electric cylinder with good waterproof performance to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An electric cylinder with good waterproof performance comprises a base and an electric cylinder body; the electric cylinder body is fixedly installed on the top of the base, a telescopic rod is slidably connected to the top of the inside of the electric cylinder body, a waterproof shell is fixedly installed on the top of the electric cylinder body outside the telescopic rod, a sealing ring is attached to the inside of the waterproof shell, a motor is fixedly installed on the top of the base on one side of the electric cylinder body, a shell is fixedly connected to the periphery of the motor, a protective cover is fixedly installed on the top of the shell, fixed plates are fixedly installed at both ends of the protective cover, connecting plates are arranged at both ends of the protective cover on the other side of the fixed plate, the outer end of the connecting plate is rotatably installed with the protective plate through a rotating shaft, the inner end of the connecting plate is fixedly connected with a connecting block, a spring is fixedly installed inside the connecting block and the connecting plate, a sliding frame is fixedly connected to one side of the spring, a clamping block is fixedly installed on one side of the sliding frame, the clamping block runs through the inside of the connecting block, and clamping grooves matching the shapes of the connecting block and the clamping block are provided at both ends of the shell, and the clamping grooves are located directly below the connecting block and the clamping block.

[0008] By installing the waterproof shell, the periphery of the telescopic rod can be protected. By installing the sealing ring, the waterproof shell and the telescopic rod can be sealed, so that water can be prevented from penetrating into the telescopic rod, achieving a waterproof effect. By inserting the connecting block into the inside of the protective cover, and then using the elastic force of the spring itself, the card block can be inserted into the inside of the protective cover to achieve the connection between the protective plate and the protective cover, so that it is convenient to use the protective cover and the protective plate to protect the top of the shell, and prevent water from directly flowing into the inside of the shell from the top and affecting the motor, achieving a waterproof effect. When the electric cylinder body needs to be installed upside down, by pushing the sliding frame to one side, the card block can be separated from the inside of the protective cover at the same time, so that it is convenient to separate the waterproof shell from the protective cover, disassemble the protective plate, fix the connecting plate, turn the protective plate upward by 180 degrees, and then push the sliding frame to one side to insert the connecting block into the inside of the shell. After loosening the sliding frame, the card block can be inserted into the inside of the shell by using the elastic force of the spring itself, so that the protective plate and the shell are connected, so that it is convenient to use the protective plate to waterproof the shell, and expand the protection range of the protective plate.

[0009] A further improvement of the technical solution of the utility model is that the shape of the protective plate is an inclined plate inclined toward the bottom of the outer end.

By opening a through hole matching the shape of the plug on the surface of the fixing plate at the bottom of the plug, the connecting plate can be fixed at two different positions on the other side of the fixing plate by using the plug.

[0017] A further improvement of the technical solution of the utility model is that a push block is fixedly installed on the other side of the sliding frame, and the push block is located on the other side of the connecting plate.

[0018] By adopting the above technical solution, in this solution, the contact area between the user's hand and the sliding frame can be enlarged by installing the pushing block, thereby facilitating pushing the sliding frame.

[0019] A further improvement of the technical solution of the utility model is that: filter plates are fixedly connected to both ends of the protective cover, and the filter plates are located on the other side of the fixed plate.

[0020] By adopting the above technical solution, in this solution, the air entering the interior of the protective cover can be filtered by installing a filter plate, thereby preventing dust from entering the interior of the protective cover and affecting the motor, thereby achieving a dust-proof effect.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides an electric cylinder with good waterproof performance. By installing a waterproof shell and a sealing ring, the waterproof shell and the telescopic rod can be sealed to prevent water from penetrating into the telescopic rod. By installing a protective cover and a protective plate, the top of the shell can be protected to prevent water from directly flowing into the inside of the shell from the top and affecting the motor, thereby achieving a waterproof effect.
