DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a portable bracket for a bearing heater comprises a bearing heater 1, a control switch 2 installed at the front end of the bearing heater 1 and a heating frame 3 provided at the top of the bearing heater 1, a bracket 4 is provided at the bottom end of the bearing heater 1, rollers 5 are installed at the four corners of the bottom end of the bracket 4, vertical frames 6 are installed on both sides of the rear end of the bracket 4, two groups of guide rods 7 are installed on the two groups of vertical frames 6, the outside of the two groups of guide rods 7 are slidably connected with guide sleeves 8, a connecting plate 9 is provided between the two groups of guide sleeves 8, a protective cover 10 is installed at the front end of the connecting plate 9, and a movable positioning component is provided on the outside of the guide sleeve 8.

[0023] By installing the bearing heater 1 on a movable bracket 4, the bracket 4 can drive the bearing heater 1 to move quickly through the roller 5 at the bottom, thereby improving the convenience during use. When the bearing heater 1 needs to heat the bearing, a protective cover 10 that can be installed on the upper end of the bracket 4 and can move laterally can be used to drive the two sets of guide sleeves 8 to move laterally along the guide rod 7, so that the protective cover 10 can be quickly moved to the outside of the heating frame 3 to protect the outside of the bearing on the heating frame 3, avoid external objects from contacting the heated bearing, and improve the convenience of the device during use.

[0024] In other embodiments, the movable positioning assembly includes a slide bar 12, a transverse plate 13, a movable plate 14, a positioning column 15, a positioning hole 16, a pull rod 17 and a reset spring 18. Two groups of slide bars 12 are installed at the front end of the guide sleeve 8. The front ends of the two groups of slide bars 12 are fixed with the transverse plate 13. The two groups of slide bars 12 are externally slidably connected with the movable plate 14. The positioning columns 15 are installed on both sides of the rear end of the movable plate 14. Two groups of positioning holes 16 are opened on the guide sleeve 8. The rear ends of the two groups of positioning columns 15 can be inserted into the positioning holes 16. The pull rod 17 is installed at the front end of the movable plate 14.

[0025] By installing a movable plate 14 that can move forward and backward on the outside of the guide sleeve 8, the movable plate 14 can drive the two groups of positioning columns 15 to quickly insert into the two groups of positioning holes 16 on the guide rod 7 under the elastic force of the two groups of slide rods 12, and quickly form a movable limiting effect on the guide sleeve 8 to prevent the protective cover 10 from being displaced during use, thereby improving the stability of the device during use. When it is necessary to move the protective cover 10, the pull rod 17 can be pulled forward, so that the movable plate 14 can drive the two groups of positioning columns 15 to move forward along the two groups of slide rods 12. When the two groups of positioning columns 15 completely leave the two groups of positioning holes 16, the protective cover 10 can be pushed laterally, so that the protective cover 10 drives the two groups of guide sleeves 8 to move toward the side ends along the guide rod 7 and leave the outside of the heating frame 3.

[0026] In other embodiments, an observation window 11 is provided at the front end of the protective cover 10, and a high temperature resistant glass is installed in the observation window 11;

[0027] This design makes it easy to directly observe the bearing on the heating rack 3 from outside the protective cover 10 through the observation window 11, so that the operator can make real-time records.

[0028] In other embodiments, two groups of through holes are formed on the horizontal plate 13, and the pull rod 17 passes through the two groups of through holes;

[0029] Through this design, the pull rod 17 can move forward and backward along the through hole on the cross plate 13 .

[0030] In other embodiments, the two ends of the return spring 18 are respectively connected to the outer wall of the movable plate 14 and the outer wall of the horizontal plate 13, and the movable plate 14 is elastically connected to the horizontal plate 13 through two sets of slide bars 12;

[0031] Through this design, the two groups of sliding rods 12 can exert elastic force on the movable plate 14 toward the guide sleeve 8 , so that the movable plate 14 can drive the two groups of positioning columns 15 to quickly insert into the two groups of positioning holes 16 .

[0032] In other embodiments, the outer wall of the pull rod 17 is provided with anti-slip textures;

[0033] This design can effectively increase the friction between the pull rod 17 and the user's hand, making it easier to pull the pull rod 17.

[0034] In other embodiments, the outer diameter of the positioning column 15 is the same as the inner diameter of the positioning hole 16;

[0035] With this design, when the end of the positioning column 15 is inserted into the positioning hole 16 , the positioning column 15 can be effectively prevented from shaking in the positioning hole 16 , thereby improving the stability of the positioning column 15 when in use.

[0036] The electrical components mentioned in this article are all connected to an external main controller and industrial power supply, and the main controller can be a conventional known device for control such as a computer.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
