Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline cleaning equipment, specifically relating to a portable grease cleaning device for narrow pipelines. Background Technology

[0002] Grease buildup in narrow pipes can easily cause blockages. Existing tools have the following shortcomings: poor portability, insufficient propulsion, large size of the electric device making it difficult to carry to the site, low cleaning efficiency, single brush / shovel cannot reciprocate, resulting in incomplete grease removal, poor adaptability, and fixed shovel head cannot be adapted to different pipe inner diameters, resulting in insufficient versatility.

[0003] Therefore, there is an urgent need for a structurally optimized grease cleaning device for narrow pipes. Utility Model Content

[0004] The purpose of this invention is to provide a portable grease cleaning device for narrow pipes, in order to solve the problem that a single brush / scraper cannot perform reciprocating operations and has low cleaning efficiency.

[0005] The technical solution of this utility model is: a portable grease cleaning device for narrow pipes, including a cleaning rod and a fixed box. The cleaning rod has a groove on its side. The fixed box has a crank-connecting rod propulsion device. The crank-connecting rod propulsion device includes two sets of symmetrically arranged cranks, two cranks in each set. A long connecting rod connects the two sets of cranks. A short connecting rod connects the two cranks in the same position in each set. A pin is provided on the side of the long connecting rod. The pin is adapted to engage with the groove. The bottom of the cleaning rod is detachably provided with an arc-shaped shovel.

[0006] As a further improvement of this utility model, a rear limiter is provided at the bottom of the cleaning rod, and a one-way pneumatic connector is provided on the rear limiter. The rear limiter is connected to the fixed box through a positioning pin.

[0007] As a further improvement of this utility model, the crank connecting rod propulsion device is provided with a rocker handle, and the fixed housing is provided with a rocker handle movable window, through which the rocker handle is connected to the rocker handle movable window.

[0008] As a further improvement of this utility model, the side of the fixed box is provided with a latch movable window, and the latch passes through the latch movable window and is matched and engaged with the groove.

[0009] As a further improvement of this utility model, the cleaning rod and the shovel head are detachably connected by fixing bolts.

[0010] The beneficial effects of this utility model are as follows:

[0011] The crank-connecting rod mechanism drives the positioning pin to reciprocate, which, through the engagement of the slot, pushes the cleaning rod up and down inside the pipe, thus scraping away grease. Reverse cranking returns the cleaning rod to its original position, and this reciprocating motion improves cleaning efficiency. The detachable, arc-shaped scraper head can be replaced according to the pipe size; a one-way pneumatic connector ensures a stable connection between the device and the pipe, and the positioning pin connects to the fixed housing to prevent loosening during operation.

[0012] Compared with the prior art, this utility model has the following advantages: 1. Portable and efficient: The crank connecting rod propulsion device has a compact structure and the rocker arm operation is labor-saving, making it suitable for narrow spaces; 2. Replaceable shovel head: It can be adapted to different pipes, improving its applicability; 3. Stable propulsion: The groove and positioning pin cooperate to ensure the linear movement of the cleaning rod, resulting in excellent cleaning effect; 4. Reliable positioning: The one-way pneumatic connector and positioning pin enhance the stability of the device and prevent displacement during operation.

[0013] This utility model is specifically a grease cleaning device suitable for narrow pipes (such as kitchen branch pipes, small oil pipelines, etc.), which is portable, efficient and highly adaptable. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-4As shown, a portable grease cleaning device for narrow pipes includes a cleaning rod 3 and a fixed housing 4. The cleaning rod 3 has a groove on its side. The fixed housing 4 has a crank-connecting rod propulsion device 10. The crank-connecting rod propulsion device 10 includes two sets of symmetrically arranged cranks 11, with two cranks 11 in each set. A long connecting rod 12 connects the two sets of cranks 11. A short connecting rod 13 connects the two cranks 11 in the same position in each set. A pin 9 is provided on the side of the long connecting rod 12. The pin 9 is adapted to engage with the groove. The bottom of the cleaning rod 3 is detachably provided with an arc-shaped shovel head 6.

[0021] The bottom of the cleaning rod 3 is equipped with a rear limiter 8, and the rear limiter 8 is equipped with a one-way pneumatic connector 2. The rear limiter 8 is connected to the fixed box 4 through the positioning pin 14.

[0022] The crank-connecting rod propulsion device 10 is equipped with a rocker handle 17, and the fixed housing 4 has a rocker handle movable window 16. The rocker handle 17 passes through the rocker handle movable window 16 and is connected to the rocker 5.

[0023] The side of the fixed housing 4 is provided with a latch movable window 15, and the latch 9 passes through the latch movable window 15 and is matched and engaged with the groove.

[0024] The cleaning rod 3 and the shovel head 6 are detachably connected by fixing bolts 7.

[0025] The following steps are included when using this utility model:

[0026] Assembly: Install the shovel head 6 at the end of the cleaning rod 3 and insert it into the pipe 1; connect the one-way pneumatic connector 2 and connect it to the fixed box 4 through the positioning pin 14; push the pin 9 into the groove of the cleaning rod 3.

[0027] Operation: Shake the crank handle 17 to push the cleaning rod 3 forward and backward, and scrape off the grease with the scraper head 6; shake it in the opposite direction to retract the cleaning rod 3 to complete the cleaning.

[0028] Maintenance: Remove fixing bolt 7 and replace shovel head 6; check the wear of crank connecting rod propulsion device 10 and ensure that the parts are tight.

[0029] The cleaning rod 3 has a groove that engages with the pin 9 of the crank-connecting rod propulsion device 10 to achieve axial movement and linear reciprocating motion, ensuring stable propulsion force. The crank-connecting rod propulsion device 10 is driven by the rocker handle 17, converting circular motion into linear propulsion force to drive the cleaning rod 3 axially. The detachable shovel head 6 has an arc-shaped cutting edge to fit the inner wall of the pipe 1. The center of the shovel head 6 can be quickly replaced to fit different pipe diameters via the fixing bolt 7, improving cleaning flexibility. The one-way pneumatic connector 2 quickly connects to the pipe 1 being cleaned. The rear limiter 8 maintains the absolute position of the one-way pneumatic connector 2 and the pipe 1, while the positioning pin 14 connects to the fixed housing 4, enhancing the stability of the device. The rocker handle 17 is operated within the rocker handle movable window 16, converting circular motion into linear propulsion force, making operation labor-saving and suitable for working in confined spaces.

[0030] This device, through its innovative structural design, enables efficient cleaning of grease from narrow pipes. It boasts advantages such as portability, stability, and replaceable scraper heads, making it suitable for industrial pipeline maintenance.
