Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher processing, and in particular to a fire extinguisher filling and drilling device. Background Technology

[0002] Dry powder fire extinguishers are a commonly used type of fire extinguisher. The cylinder of a dry powder fire extinguisher is filled with dry powder extinguishing agent. Dry powder extinguishing agent is free-flowing and dry, and is composed of inorganic salts and pulverized and dried additives. It can effectively extinguish initial fires. In the production process of dry powder fire extinguishers, the fire extinguisher cylinder is processed first, and then the dry powder extinguishing agent is filled into the fire extinguisher cylinder. After the dry powder is filled, the suction pipe is inserted to install the fire extinguisher valve.

[0003] According to announcement number CN220407181U, a fire extinguisher filling and drilling device addresses the problems of existing equipment typically failing to uniformly fill the fire extinguisher canister and lacking the ability to limit the fire extinguisher's position during filling and drilling, resulting in poor production stability. The proposed solution includes a base, a support plate fixedly mounted on the top of the base, a housing fixedly mounted on the top of the support plate, a motor fixedly mounted on the top of the base, a rotating mechanism connected to the motor's output shaft, two second transmission rods rotatably connected to the housing, and two third transmission rods fixedly connected to the inner side wall of the housing. This invention is simple to operate, convenient to use, can uniformly fill the fire extinguisher canister, and can limit the fire extinguisher's position during filling and drilling, thus improving production stability during fire extinguisher filling and drilling.

[0004] However, in actual use, most fire extinguishers are processed by first taking them out and placing them for drilling. After releasing the clamps, the fire extinguishers still need to be manually taken to the filling station. This is mostly a separate design, and processing them separately is quite troublesome. Therefore, improvements have been made based on the problems mentioned above. Utility Model Content

The fixing block 316 is slidably connected to the inner wall of the handle 315, mainly serving to limit the position of the handle 315. The outer wall of the fixing plate 311 is provided with a through groove 312, and the handle 315 is slidably connected to the outer wall of the through groove 312, so that the handle 315 extends and provides a certain limiting support. The top of the inner wall of the fixing plate 311 is provided with two fixing holes 313, which are respectively opened at both ends of the opening of the fixing plate 311. There are two springs 317, which are respectively connected to the front and rear ends of the fixing block 316. The bottom of the inner turntable 314 is fixedly connected to the drilling machine 7.

The filling mechanism includes a storage tank 4, a connecting pipe 5, and a filling machine 6. The storage tank 4 is fixedly connected to the top of the frame 1 to support the storage tank 4. The bottom of the storage tank 4 is fixedly connected to the connecting pipe 5 to transfer the extinguishing agent. The bottom of the inner turntable 314 is fixedly connected to the filling machine 6 to support the filling machine 6. The extension end of the connecting pipe 5 is fixedly connected to the filling machine 6.

[0029] Reference Figure 1 , Figure 2 , Figure 7The bottom of the hydraulic cylinder 2 is fixedly connected to a connecting plate 8, which provides support for the connecting plate 8.

The toothed plate 912 is slidably connected to the outer wall of the guide rail 911. The outer wall of the toothed plate 912 has insertion holes 913. Multiple sets of insertion holes 913 are provided for easy adjustment according to needs.

The position of the two sets of toothed plates 912 can be quickly adjusted by setting the connecting plate 11. The inner wall of the frame 1 is rotatably connected to a bidirectional screw 12, which supports the bidirectional screw 12. The outer wall of the bidirectional screw 12 is fixedly connected to a gear 13. The rotation of the bidirectional screw 12 is controlled by the meshing of the gear 13 with the toothed plate 912. The teeth of the gear 13 mesh with the teeth on the inner wall of the toothed plate 912.

[0030] Reference Figure 1 , Figure 4 A limiting rod 15 is fixedly connected to the frame 1. A clamping mechanism 14 is provided on the bidirectional screw 12, which supports and moves the clamping mechanism 14. The clamping mechanism 14 includes a sliding plate 141. The inner wall of one end of the sliding plate 141 is threadedly connected to the outer wall of the bidirectional screw 12, allowing the sliding plate 141 to move along the bidirectional screw 12. The inner wall of the other end of the sliding plate 141 is slidably connected to the outer wall of the limiting rod 15, which limits the sliding plate 141. A groove is provided on the inner wall of the sliding plate 141, and a slider 142 is slidably connected to the inner wall of the groove. The slider can be adjusted according to different sizes of fire extinguishers. The position control clamp 143 is fixed to the slider 142. The top of the slider 142 is threaded with a bolt B144, which serves to fix the slider 142. The outer wall of the slider 142 is fixedly connected with the clamp 143, which serves to connect the clamp 143 and clamp the fire extinguisher. The outer surface of the clamp 143 is hard, and the inside is deformable, so the clamp 143 can be slightly deformed to increase the clamping effect. The bottom of the frame 1 is fixedly connected with a processing table 16. An opening is opened on the left side of the frame 1 to facilitate the scraping and cleaning of debris left after drilling on the worktable.

[0031] Working principle: First, the operator manually places the fire extinguisher body on the processing table 16. The lifting mechanism drives the bottom connecting plate 8 downward, thereby causing the toothed plate 912 on the connecting plate 8 to move downward. When the toothed plate 912 moves downward along the guide rail 911, it drives the gear 13 on the outer wall of the bidirectional screw 12 to rotate, thereby driving the bidirectional screw 12 to rotate continuously. This controls the clamping mechanism 14 to clamp the fire extinguisher. The toothed plate 912 can be adjusted according to different specifications of the fire extinguisher body. When the fire extinguisher body is thicker, the length of the toothed plate 912 is adjusted upward, thus shortening the stroke of the toothed plate 912 to fix the thicker fire extinguisher body. If the fire extinguisher body is smaller, the stroke of the toothed plate 912 is extended, so that the clamping mechanism 14 continues to move along the bidirectional screw 12. The movement is fixed, and an insertion hole 913 is opened behind the toothed plate 912, which is fixed to the hole opened behind the connecting plate 8 by bolt A914. At the same time, the slider 142 on the sliding plate 141 can move and be fixed by bolt B144, so that the clamping plate 143 can be adjusted and fixed according to the size of different specifications of fire extinguisher cylinders. Finally, the lifting mechanism drives the fixing plate 311 to descend and drill holes in the fire extinguisher body first, and then the filling machine 6 fills the fire extinguishing agent into it. By pulling the handle 315 to rotate the inner turntable 314, the fixing block 316 inside the handle 315 is inserted into the fixing hole 313 opened in the inner wall of the fixing plate 311 under the action of spring 317, so that the drilling machine 7 and the filling machine 6 can be switched to quickly complete the drilling and filling of the fire extinguisher body.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
