DETAILED DESCRIPTION

[0023] It should be noted that the embodiments and features in the application can be combined with each other without conflict. The application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] In order for those skilled in the art to better understand the application, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings of the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the application.

[0025] As Figures 1-4 shown, the application provides a push rod motor mounting protection device, comprising a lifting table assembly 1, the lifting table assembly 1 has a support 11, the support 11 is suitable for contacting with the ground and supporting the lifting table assembly 1, and a fixed part 12 is fixedly installed on the support 11, the fixed part 12 has a groove (not marked in the figure), and the upper end position of the fixed part 12 is conical;

[0026] And a telescopic assembly 2 is inserted in the groove, the telescopic assembly 2 includes a rubber buffer pad 21 inserted in the groove, and a push rod motor 23 is installed on the rubber buffer pad 21, and a slot 22 is formed in the rubber buffer pad 21, and a support rod 13 is inserted in the slot 22, the support rod 13 is a hollow structure, and the support rod 13 is sleeved on the push rod motor 23, so that when the support rod 13 is inserted in the slot 22, the position close to the upper end of the fixed part 12 is in contact with the surface of the support rod 13, and the support rod 13 is fixed on the fixed part 12 by connecting bolts (not shown) between the fixed part 12 and the support rod 13;

[0027] The fixed part 12 is fixed on the support 11, and the groove provides a basis for the installation of the telescopic assembly 2. The existence of the groove enables the telescopic assembly 2 to be accurately inserted and initially positioned, and the rubber buffer pad 21 is inserted in the groove, which can effectively buffer the vibration generated by the push rod motor 23 during operation, reduce the transmission of vibration to the support 11 and the entire lifting table assembly 1, and effectively buffer the vibration generated by the push rod motor 23 during operation, reduce the noise during equipment operation, and the support rod 13 is sleeved on the push rod motor 23 and fixedly connected with the fixed part 12, which not only provides additional support and protection for the push rod motor 23 to prevent displacement or shaking during operation, but also blocks dust, debris and other objects from entering the push rod motor 23 to some extent, prolonging the service life of the motor;

[0028] And a connecting plate 24 is fixedly installed at the telescopic end of the push rod motor 23, and two groups of push rods 25 are fixedly installed on the connecting plate 24, the push rods 25 are suitable for pushing the lifting table assembly 1 to lift, and a receiving platform 213 is clamped in one end of the support rod 13, the receiving platform 213 is movably sleeved on the two groups of push rods 25, a fixed seat 26 is fixedly installed on the receiving platform 213, and two groups of adsorption units are installed on the fixed seat 26;

[0029] The telescopic end of the push rod motor 23 is connected with the connecting plate 24, and the telescopic power of the motor is transmitted to the two groups of push rods 25 through the connecting plate 24, when the push rod motor 23 starts and telescopes, the push rods 25 move linearly under the driving of the push rod motor 23, and then push the lifting table assembly 1 to realize the lifting function, providing a core power transmission mechanism for the electric lifting table;

[0030] The adsorption unit comprises a first clamping ring 27 fixedly installed on the fixed seat 26, a second clamping ring 28 movably connected on the first clamping ring 27, and a movable rod 210 hingedly connected on the first clamping ring 27 at a position away from the hinge point, while a clamping groove 29 adapted for the movable rod 210 is formed on the second clamping ring 28, and a sponge block 212 is arranged on the contact area of the first clamping ring 27 and the second clamping ring 28 with the push rod 25, which is used to absorb water droplets attached to the push rod 25, and a screw member 211 is threadedly connected on the movable rod 210, which can be a nut;

[0031] Therefore, when the first clamping ring 27 and the second clamping ring 28 are attached, the movable rod 210 is clamped into the clamping groove 29, so that the first clamping ring 27 and the second clamping ring 28 tightly clamp the push rod 25, and then the screw member 211 is tightened and attached to the second clamping ring 28 to tightly clamp the push rod 25. The sponge block 212 is arranged on the contact area of the two clamping rings with the push rod 25, which has good water absorption and can absorb water droplets attached to the surface of the push rod 25, and is convenient for cleaning the sponge block 212 after long-term use;

[0032] And a protection assembly 4 is installed on the support rod 13, which comprises an angle plate 41 fixedly installed on the side surface of the support rod 13, a guide rod 47 fixedly installed on the angle plate 41, a sliding sleeve 42 slidably installed on the guide rod 47, and a protection shell 46 fixedly installed on the sliding sleeve 42, which is sleeved on the support rod 13, and the sliding sleeve 42 has a hooking part 43, and a rotating handle 44 is rotatably installed on the hooking part 43, which has a protruding part 45;

[0033] The protection shell 46 can slide along the guide rod 47, and the user can flexibly adjust the position of the protection shell 46 on the support rod 13 according to actual needs to protect the push rod 25 after telescopic adjustment, and the hooking part 43 of the sliding sleeve 42 is used to install the rotating handle 44, which can freely rotate around the connection point with the hooking part 43. When the protection shell 46 moves to the desired position, for example, completely shielding the push rod 25 after telescopic adjustment, the user holds and rotates the rotating handle 44. The protruding part 45 on the rotating handle 44 will move close to the guide rod 47 with rotation, and when the protruding part 45 contacts the guide rod 47, the friction between the protruding part 45 and the surface of the guide rod 47 prevents the sliding sleeve 42 from continuing to slide, thereby fixing the position of the protection shell 46;

[0034] The user can freely and flexibly adjust the position of the protective shell 46 on the support rod 13 according to the actual position of the telescopic adjustment of the push rod 25. This means that whether the push rod 25 is in a fully extended state or a retracted state, the effective protection of the protective shell 46 can be achieved by moving it, meeting the protection needs in different use scenarios, and greatly improving the applicability of the protection device.

[0035] In summary: the push rod motor mounting protection device of the present application precisely receives the telescopic assembly 2 through the groove of the fixing part 12, wherein the rubber buffer pad 21 effectively absorbs the vibration generated when the push rod motor 23 is operating, reduces the spread of noise to other parts of the lifting table, and ensures the quietness of the use environment. The hollow support rod 13 is sleeved with the push rod motor 23 and fastened with the fixing part 12 through bolts, which not only enhances the stability of the motor, but also blocks the invasion of dust and sundries, prolonging the service life of the motor.

[0036] The telescopic power of the push rod motor 23 is transmitted to the push rod 25 through the connecting plate 24, and the lifting table assembly 1 is realized smoothly. The receiving platform 213 assists the movement of the push rod 25 and provides a mounting basis for the adsorption unit. The first clamping ring 27 and the second clamping ring 28 of the adsorption unit tightly clamp the push rod 25 through the movable rod 210 and the screw part 211, and the sponge block 212 in the contact area can efficiently absorb the water droplets condensed on the surface of the push rod 25 in a humid environment, preventing moisture from entering the motor and avoiding short circuit, corrosion and other faults.

[0037] At the same time, the protective shell 46 can slide along the guide rod 47, and the user can conveniently rotate the handle 44 to adjust the position of the protective shell 46 according to the telescopic state of the push rod 25. When the protective shell 46 is in place, it is fixed through the friction force between the protruding part 45 and the guide rod 47, effectively blocking small sundries such as clothing fibers, loose cables, paper debris, etc. from approaching the push rod 25, avoiding being sucked into the inside of the push rod motor 23, and eliminating safety hazards.

[0038] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
