[0002] When the existing mops are used to clean the space under the sofa or under the bed, since the height of such areas is relatively low and small, the cleaners need to bend down, squat or even kneel on the ground to carry out the cleaning work, which brings great inconvenience to the cleaning work and is time-consuming and laborious at the same time. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bendable mop rod. By arranging a bendable nylon mop rod inside the main body of the mop rod, the included angle between the mop rod and the mop cloth can be changed, which is convenient for the cleaner to insert the mop cloth into the flat and low areas when standing, and solves the problem that it is inconvenient to clean the flat and low areas with the existing mops;

[0004] At the same time, the nylon mop rod can be telescopic, so that the insertion depth of the mop cloth and the bending angle of the nylon mop rod can be further adjusted, and the needs of various different working conditions can be met.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A bendable mop rod includes a hollow main body of the mop rod. The lower end of the main body of the mop rod is inserted into a clamping head. A telescopic rod is sleeved at the lower end of the main body of the mop rod. A telescopic nylon mop rod is sleeved inside the telescopic rod. A threaded connection part is formed at the end of the nylon mop rod; a locking component is arranged between the telescopic rod and the nylon mop rod.

[0007] Through the above technical solution, the threaded connection part is threadedly connected with one end of the mop plate. The structure of the mop plate is generally a rectangular plate. A threaded connection head is arranged in the middle of a short side of the rectangular plate, and this threaded connection head is connected with the connection part; during the cleaning work, hold the main body of the mop rod. After the mop cloth is installed on the mop plate, the mop cloth is attached to the ground. Pressing down the main body of the mop rod can make the nylon mop rod bend, and an included angle of 60-90 degrees can be generated between the main body of the mop rod and the ground, so that the lower flat area can be cleaned without bending down or squatting.

[0008] At the same time, the nylon mop rod can be telescopic. The greater the length of the extended nylon mop rod, the greater the bending angle of the nylon mop rod. The extended length of the nylon mop rod can be limited by the locking component.

[0009] The present utility model is further configured as follows: The locking assembly includes a socket and a locking seat fixed to the lower end of the telescopic rod. The locking seat is formed with a nylon drag rod guiding hole axially penetrating therethrough and a convex platform protruding upward. The nylon drag rod passes through the nylon drag rod guiding hole. A sunken groove is formed on the convex platform, and a pair of through holes arranged coaxially are formed on the middle side wall of the sunken groove. A support shaft is sleeved and fixed in the pair of through holes. A locking buckle is rotatably connected to the support shaft, and the locking buckle is placed in the sunken groove;

[0010] A retaining platform is formed at the front end of the locking buckle, and a relief hole is formed on the front bottom surface of the sunken groove; A number of linearly evenly distributed retaining holes are formed on the upper end surface of the nylon drag rod; The protruding end of the retaining platform passing through the relief hole is inserted into one of the retaining holes;

[0011] A compression spring is provided between the end of the locking buckle far from the retaining platform and the sunken groove.

[0012] Through the above technical solution, the movement of the nylon drag rod in the telescopic rod can be restricted by inserting the retaining platform into the retaining hole; When it is necessary to move the nylon drag rod, press one end of the locking buckle close to the compression spring. Through the action of the support shaft, the other end of the locking buckle tilts upward to drive the retaining platform to disengage from the retaining hole. At this time, the nylon drag rod can freely expand and contract in the locking seat, so as to adjust the extended length of the nylon drag rod. After the adjustment is completed, release the locking buckle, and under the action of the compression spring, the locking buckle can automatically reset to make the retaining platform insert into another retaining hole again;

[0013] The nylon drag rod guiding hole can guide and support the nylon drag rod.

The upper end of the compression spring presses against the bottom surface of the locking buckle. An insertion rod is formed on the bottom surface of the locking buckle, and the insertion rod is inserted into the spring retaining sleeve.

[0015] Through the above technical solution, by arranging the compression spring on the hemispherical spring seat, the compression spring can also change its position with the hemispherical spring seat when pressing the locking buckle, so that the compression spring can always face the locking buckle directly, and the locking buckle can always be effectively supported.

[0016] The present utility model is further configured as follows: The nylon drag rod includes two planes arranged up and down and two arc surfaces arranged coaxially on the left and right sides of the two planes; The contour enclosed by the two planes and the two arc surfaces is arranged in cooperation with the inner wall contour of the nylon drag rod guiding hole.

[0017] Through the above technical solution, the cross section of the nylon drag rod is generally in the shape of a flat waist, which is convenient for bending the nylon drag rod.

[0018] The utility model is further arranged as follows: several pairs of linearly evenly distributed side deep grooves are formed on the outer edge of the upper plane, several linearly evenly distributed deep holes are formed in the middle of the upper plane, several pairs of linearly evenly distributed side shallow grooves are formed on the edge of the lower plane, and several linearly evenly distributed shallow holes are formed in the middle of the lower plane.

[0019] By arranging several side deep grooves, deep holes, side shallow grooves and shallow holes, the bendability of the nylon drag rod can be further improved, and at the same time, the flexibility of the nylon drag rod can be enhanced.

[0020] The utility model is further arranged as follows: the inner diameter of the telescopic rod and the outer diameter of the arc surface are in clearance fit, which can support the nylon drag rod extending into the telescopic rod and help the nylon drag rod to recover its deformation.

[0021] The outstanding effect of the utility model is:

[0022] Compared with the prior art, by arranging a bendable nylon drag rod in the drag rod main body, the included angle between the drag rod and the drag cloth can be changed, which is convenient for the cleaning personnel to intake the drag cloth into the flat and lower area for cleaning while standing, and solves the problem that it is inconvenient to clean the flat and lower area with the existing mop.

[0023] At the same time, the nylon drag rod is telescopic, so that the extending depth of the drag cloth and the bending angle of the nylon drag rod can be further adjusted, and the requirements of various different working conditions can be met. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will further describe in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0041] The following reference Figures 1 to 6 will describe the present invention:

[0042] A bendable drag rod includes a drag rod main body 10 provided hollow. The lower end of the drag rod main body 10 is inserted and sleeved on a clamping head 11. The lower end of the drag rod main body 10 is sleeved with a telescopic rod 20. A telescopic nylon drag rod 30 is sleeved inside the telescopic rod 20. A threaded connection part 308 is formed at the end of the nylon drag rod 30. A locking assembly 40 is provided between the telescopic rod 20 and the nylon drag rod 30.

[0043] The threaded connection part is connected to one end of the drag plate by a threaded connection. The structure of the drag plate is roughly a rectangular plate. A threaded connection head is provided in the middle of one short side of the rectangular plate, and the threaded connection head is connected to the connection part. During cleaning, the drag rod body is held in the hand, and the drag plate is equipped with a mop and the mop is placed on the ground. The nylon drag rod can be bent by pressing the drag rod body downward, so that an angle of 60-90 degrees is generated between the drag rod body and the ground, so that a person can clean a lower flat area without bending or squatting.

[0044] At the same time, the nylon tow rod is retractable. The longer the nylon tow rod is extended, the greater the bending angle of the nylon tow rod is. The extended length of the nylon tow rod can be limited by the locking assembly.

[0045] The locking assembly 40 includes a locking seat 401 which is inserted and fixed to the lower end of the telescopic rod 20. The locking seat 401 is formed with an axially penetrating nylon drag rod guide hole 402 and an upwardly protruding boss 403. The nylon drag rod 30 passes through the nylon drag rod guide hole 402. The boss 403 is formed with a sink 404. A pair of coaxial through holes 405 are formed on the middle side wall of the sink 404. A support shaft 41 is sleeved and fixed in the pair of through holes 405. A locking buckle 42 is rotatably connected to the support shaft 41. The locking buckle 42 is placed in the sink 404.

The compression spring 43 is inserted into the outside of the spring retaining sleeve 441 and its lower end is pressed against the hemispherical head spring seat 44, and the upper end of the compression spring 43 is pressed against the bottom surface of the locking buckle 42. A plug rod 422 is formed on the bottom surface of the locking buckle 42, and the plug rod 422 is inserted into the spring retaining sleeve 441.

[0051] By arranging the compression spring on the hemispherical head spring seat, when the locking buckle is pressed, the compression spring can also change position with the hemispherical head spring seat so that the compression spring can always face the locking buckle directly, so that the locking buckle can always be effectively supported.

[0052] The nylon tow bar 30 includes two upper and lower planes 302 and two coaxial arc surfaces 303 arranged on the left and right sides of the two planes 302 ; the contour enclosed by the two planes 302 and the two arc surfaces 303 is matched with the inner wall contour of the nylon tow bar guide hole 402 .

[0053] The cross section of the nylon tow bar is generally flat and waist-shaped, which facilitates the bending of the nylon tow bar.

[0054] The outer edge of the upper plane 302 is formed with a plurality of pairs of linearly evenly distributed side deep grooves 304, the middle of the upper plane 302 is formed with a plurality of linearly evenly distributed deep countersunk holes 305, the edge of the lower plane 302 is formed with a plurality of pairs of linearly evenly distributed side shallow grooves 306, and the middle of the lower plane 302 is formed with a plurality of linearly evenly distributed shallow countersunk holes 307.

[0055] By providing a plurality of side deep grooves, deep countersunk holes, side shallow grooves and shallow countersunk holes, the bendability of the nylon tow bar can be further improved, and the flexibility of the nylon tow bar can be enhanced.

[0056] The inner diameter of the telescopic rod 20 and the outer diameter of the arc surface 303 are matched with each other in a clearance, so as to support the nylon drag rod inserted into the telescopic rod and help the nylon drag rod to recover its deformation.
