Description

Technical Field

[0001] The utility model relates to the technical field of cleaning brushes, in particular to a cleaning brush for a cement fineness detection screen. Background Art

[0002] Cement fineness test screen cleaning brush plays an important role in ensuring the accuracy of cement fineness test and the reuse of screen. In practical applications, cement fineness test screen cleaning brush usually needs to have the following characteristics:

[0003] 1. The soft but resilient bristles can penetrate deep into the screen holes to remove residual cement particles without damaging the screen;

[0004] 2. The appropriate brush head shape and size fits closely with the structure of the screen to achieve comprehensive and effective cleaning;

[0005] 3. Durable material, can withstand frequent use and erosion of cement materials, not easy to deform or damage;

[0006] 4. Good cleaning effect, can completely remove the attachments on the screen, ensuring the air permeability and screening accuracy of the screen.

[0007] Currently, there are some problems with the use of cleaning brushes for cement fineness detection screens. The bristles of some cleaning brushes are too soft and lack sufficient toughness to effectively remove stubborn cement residues, resulting in incomplete cleaning. The shape of the brush head of some cleaning brushes does not match the screen, resulting in blind spots and affecting the cleaning quality. Some cleaning brushes are made of materials that are not resistant to wear and corrosion. After a period of use, the bristles deform and fall off, reducing the cleaning effect and service life. Moreover, some cleaning brushes are prone to generating static electricity during the cleaning process, absorbing cement dust, causing secondary pollution, and affecting the cleaning effect. In addition, some cleaning brushes are inconvenient to operate, which increases the difficulty and time cost of cleaning work.

[0008] For example, a Chinese patent discloses a cleaning brush, patent number: CN214340756U, which is installed together with the shell through a mounting tube through reinforcing ribs, thereby improving the stability of the shell and thus increasing its service life.

[0009] However, there is a prominent problem with the above method. The brush head and soft bristles in the above device are fixedly connected in the cleaning brush. Frequent friction with the cement fineness detection screen over a long period of time will cause serious wear of the bristles of the brush head. Since it is a fixed connection, the brush head or bristles cannot be replaced individually, and the cleaning brush can only be replaced as a whole, which increases the cost of use. Utility Model Content

[0010] (1) Technical problems solved

[0011] In response to the deficiencies in the prior art, the utility model provides a cement fineness detection screen cleaning brush, which solves the technical problem that the brush head and soft bristles in the above-mentioned device are fixedly connected in the cleaning brush, and frequent friction with the cement fineness detection screen for a long time will cause severe wear of the bristles of the brush head. Due to the fixed connection, the brush head or bristles cannot be replaced individually, and the cleaning brush can only be replaced as a whole, which increases the cost of use.

[0012] (2) Technical solution

[0013] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0014] A cement fineness detection screen cleaning brush comprises a mounting shell, wherein two bidirectional threaded rods are rotatably connected to the inside of the mounting shell, and a hexagonal slot is provided inside the two bidirectional threaded rods.

[0016] Preferably, two groups of round rods are fixedly connected inside the installation shell.

[0017] Preferably, a handle is sleeved inside the installation shell, and a sliding groove is opened inside the installation shell.

[0018] Preferably, a comb plate is slidably connected to the interior of the slide groove, and an eccentric block is rotatably connected to the interior of the mounting shell.

[0019] Preferably, two groups of spring limit blocks are slidably connected inside the installation shell.

[0020] (3) Beneficial effects

[0021] 1. When the brush head needs to be replaced after long-term use, use an Allen wrench to insert it into the hexagonal slot and twist it to drive the bidirectional threaded rod to rotate. During the rotation of the bidirectional threaded rod, the two clamping blocks connected on the surface are driven to slide in opposite directions. The two clamping blocks slide to loosen the clamping of the cylindrical block. At this time, the brush head can be pulled out for replacement. The operation is simple and convenient, which is conducive to improving the convenience of the brush head replacement operation. By setting a brush head that is easy to replace, it is conducive to extending the reusability and service life of the device.

[0022] 2. After the screen is cleaned, hold the eccentric block and turn it ninety degrees. The eccentric block is eccentrically connected in the mounting shell and fits the surface of the comb plate to limit it. Twist the eccentric block to loosen the limit on the comb plate. At this time, pull the comb plate out of the slide slot and slide the bristles in the brush head to clean them. The comb plate is limited and fixed by the eccentrically connected eccentric block to improve the carrying stability of the comb plate. The comb plate that can be taken out at any time makes it more convenient to comb and clean the brush head, thereby ensuring the cleaning ability of the brush head. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The embodiment of the present application provides a cement fineness detection screen cleaning brush, which effectively solves the problem that the brush head and soft bristles in the above-mentioned device are fixedly connected in the cleaning brush, and frequent friction with the cement fineness detection screen for a long time will cause the bristles of the brush head to be severely worn. Due to the fixed connection, the brush head or bristles cannot be replaced separately, and the cleaning brush can only be replaced as a whole, which increases the cost of use. When the brush head needs to be replaced after long-term use, an Allen wrench is inserted into the hexagonal slot and twisted to drive the bidirectional threaded rod to rotate. During the rotation of the bidirectional threaded rod, the two clamping blocks connected on the surface are driven to slide in opposite directions. The two clamping blocks slide to loosen the clamping of the cylindrical block. At this time, the brush head can be pulled out for replacement. The operation is simple and convenient, which is conducive to improving the convenience of the brush head replacement operation. By providing a brush head that is easy to replace, the reusability and service life of the device are extended.

[0031] Example

Due to the fixed connection, the brush head or the bristles cannot be replaced separately, and the cleaning brush can only be replaced as a whole, which increases the cost of use. The overall idea is as follows: A cement fineness detection screen cleaning brush, including a mounting shell 11, the mounting shell 11 has two bidirectional threaded rods 12 rotatably connected inside, the two bidirectional threaded rods 12 are provided with hexagonal slots 13 inside, the outer surfaces of the two bidirectional threaded rods 12 are threadedly connected to a group of clamping blocks 14, the outer surfaces of the two groups of clamping blocks 14 are sleeved with return springs 15, the mounting shell 11 is internally slidably connected to a brush head 16, the upper end of the brush head 16 is fixedly connected to a quick-release mechanism, the quick-release mechanism includes two cylindrical blocks 17, the two cylindrical blocks 17 are fixedly connected to the upper end of the brush head 16, and the two cylindrical blocks 17 are respectively connected to the two The two clamping blocks 14 are adapted to each other, and arc grooves 18 are provided inside the two sets of clamping blocks 14. Two sets of round rods 19 are fixedly connected to the inside of the mounting shell 11, and the two sets of round rods 19 are in fit with the two sets of arc grooves 18. When the brush head 16 needs to be replaced after long-term use, an inner hexagonal wrench is inserted into the hexagonal slot 13 and screwed to drive the two-way threaded rod 12 to rotate (the two threads set on the outside of the two-way threaded rod 12 are rotated in opposite directions). During the rotation of the two-way threaded rod 12, the two clamping blocks 14 connected on the surface are driven to slide in opposite directions. The two clamping blocks 14 slide and release the clamping of the cylindrical block 17. At this time, the brush head 16 can be pulled out for replacement. The operation is simple and convenient, which is conducive to improving the convenience of the brush head 16 replacement operation. By setting the brush head 16 that is easy to replace, it is conducive to extending the reusability and service life of the device. During the sliding process of the two sets of clamping blocks 14, the round rods 19 set in the mounting shell 11 are in fit with them to limit them, thereby ensuring stability during the sliding process.

[0033] A handle 21 is sleeved inside the mounting shell 11. After the cement fineness detection screen has been used for a long time, cement particles are likely to accumulate on the surface. At this time, hold the handle 21 to fit the brush head 16 connected to the mounting shell 11 against the surface of the screen and move it back and forth along the surface of the screen to brush and clean it.

[0034] A slide groove 22 is provided inside the mounting shell 11, and a comb plate 23 is slidably connected inside the slide groove 22. An eccentric block 24 is rotatably connected inside the mounting shell 11, and the eccentric block 24 fits the outer surface of the comb plate 23. Two sets of spring limit blocks 25 are slidably connected to the mounting shell 11, and the two sets of spring limit blocks 25 are both clamped inside the brush head 16. After the screen cleaning is completed, the eccentric block 24 is held and twisted ninety degrees. The eccentric block 24 is eccentrically connected to the mounting shell 11 and fits the surface of the comb plate 23 to limit it. The eccentric block 24 is twisted to loosen the limit on the comb plate 23. At this time, the comb plate 23 is pulled out of the slide groove 22, and the bristles in the brush head 16 are slidably cleaned (the through groove opened in the comb plate 23 and the bristle size on the surface of the brush head 16 are consistent with each other). The combing plate 23 is adapted to the size, and the combing plate 23 is combed back and forth to clean the residue on the surface of the brush head 16). The combing plate 23 is limited and fixed by the eccentric block 24 connected eccentrically, so as to improve the carrying stability of the combing plate 23. The combing plate 23 that can be removed at any time is more convenient for combing and cleaning the brush head 16, thereby ensuring the cleaning ability of the brush head 16. The new brush head 16 is slid out of the mounting shell 11. During the sliding process of the brush head 16, the spring limit block 25 is fitted with the inclined surface and squeezed to slide to the side away from the brush head 16. When the brush head 16 slides and fits the inner surface of the mounting shell 11, the spring limit block 25 slides and is clamped in the brush head 16. During the sliding clamping operation, its metal surface fits the surface of the brush head 16 and makes a sound to remind the staff that it has been installed in place.

[0035] In response to the problems existing in the prior art, the utility model provides a cement fineness detection screen cleaning brush. When the brush head 16 needs to be replaced after being used for a long time, an Allen wrench is inserted into the hexagonal slot 13 and twisted to drive the bidirectional threaded rod 12 to rotate. During the rotation of the bidirectional threaded rod 12, the two clamping blocks 14 connected on the surface are driven to slide in opposite directions. The two clamping blocks 14 slide to release the clamping of the cylindrical block 17. At this time, the brush head 16 can be pulled out for replacement. The operation is simple and convenient, which is conducive to improving the convenience of the brush head 16 replacement operation. By providing a brush head 16 that is easy to replace, the reusability and service life of the device are extended.

[0036] Working principle:

[0037] The first step is that after the cement fineness detection screen has been used for a long time, cement particles are likely to accumulate on the surface. At this time, hold the handle 21 to fit the brush head 16 connected to the mounting shell 11 to the surface of the screen and move back and forth along the surface of the screen to brush and clean it.

[0038] The second step is to replace the brush head 16 after long-term use, use an Allen wrench to insert the hexagonal slot 13, and twist it to drive the two-way threaded rod 12 to rotate (the two threads arranged on the outside of the two-way threaded rod 12 are rotated in opposite directions). During the rotation of the two-way threaded rod 12, the two clamping blocks 14 connected on the surface are driven to slide in opposite directions, and the two clamping blocks 14 slide and release the clamping of the cylindrical block 17. At this time, the brush head 16 can be pulled out for replacement, which is simple and convenient to operate, which is conducive to improving the convenience of replacing the brush head 16. By setting the convenient replacement of the brush head 16, it is conducive to extending the reusability and service life of the device. During the sliding process of the two sets of clamping blocks 14, the round rod 19 arranged in the mounting shell 11 is fitted with it to limit it, ensuring stability during the sliding process. After the screen is cleaned, hold the eccentric block 24 and twist it ninety degrees. The eccentric block 24 is eccentrically connected in the mounting shell 11 and fits the surface of the comb plate 23 to limit it. The eccentric block 24 is twisted to loosen the limit of the combing plate 23. At this time, the combing plate 23 is pulled out from the slide groove 22 to slide and clean the bristles in the brush head 16 (the through grooves in the combing plate 23 are adapted to the size of the bristles on the surface of the brush head 16, and the combing plate 23 is combed back and forth to clean the residue on the surface of the brush head 16). The eccentric block 24 connected eccentrically limits and fixes the combing plate 23, which improves the stability of the combing plate 23 when carried, and the combing plate 23 that can be taken out at any time is more convenient. Comb and clean the brush head 16 to ensure the cleaning ability of the brush head 16, and slide the new brush head 16 out of the mounting shell 11. During the sliding process, the brush head 16 is in contact with the inclined surface of the spring limit block 25 and squeezed to slide to the side away from the brush head 16. When the brush head 16 slides and contacts the inner surface of the mounting shell 11, the spring limit block 25 slides and is clamped in the brush head 16. During the sliding clamping operation, its metal surface contacts the surface of the brush head 16 and makes a sound to remind the staff that it has been installed in place.

[0039] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
