Specific implementation mode
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0025] Refer to Figure 1 - Figure 2 , Figure 4 , an embodiment provided by the present utility model: A portable pH meter for fabrics includes a shell 1. A detection tube 2 is provided on the lower surface of the shell 1. The shell 1 and the detection tube 2 are components of the pH meter. It is a pen-type pH meter with a small size, which is convenient for users to carry. And those skilled in the art can implement it. Since it is prior art, it will not be described in detail in this case. A protective component is provided on the outer wall of the detection tube 2. A chute 5 is opened on the rear surface of the shell 1. A fixing component is provided on the rear surface of the shell 1. The protective component includes a cylindrical shell 31. The cylindrical shell 31 can control the opening and closing of the protective plate 1 33 and the protective plate 2 36 by moving up and down, improving convenience and avoiding the loss of the protective shell of the detection tube 2, thus improving practicability. At the same time, the bottom end of the cylindrical shell 31 is made of a plastic material with certain elasticity to ensure that the protective plate 1 33 and the protective plate 2 36 can be opened smoothly. The cylindrical shell 31 is slidably connected to the outer wall of the detection tube 2. A rotating rod 39 is rotatably connected to the inner wall on the right side of the bottom end of the cylindrical shell 31. The rotating rod 39 can make the protective plate 1 33 rotate stably. The protective plate 1 33 is fixedly connected to the outer wall of the rotating rod 39. When the protective plate 1 33 and the protective plate 2 36 are closed, the bottom end of the detection tube 2 can be sealed and protected. The top end on the right side of the protective plate 1 33 slides on the inner wall on the right side of the bottom end of the cylindrical shell 31.
[0026] Refer to Figure 2 - Figure 3 ,Figure 5 , the fixing component includes a sliding block 43 which is slidably connected to the inner wall of the chute 5. The sliding block 43 is adapted to the chute 5 to ensure the stability of movement. A fixing block 42 is fixedly connected to the rear surface of the sliding block 43. The sliding block 43 can be connected to the elastic clamping block 41 through the fixing block 42. The front surface of the fixing block 42 slides on the rear surface of the housing 1. An elastic clamping block 41 is fixedly connected to the rear surface of the fixing block 42. The elastic clamping block 41 has a certain elasticity, and its bottom end can be pulled open and clamped on an object to fix the pH meter.
[0027] Refer to Figure 1 , Figure 4 , Figure 6 , a torsion spring 35 is sleeved on the outer wall of the rotating rod 39. The torsion spring 35 has a certain elasticity to ensure the stability of the closing between the longitudinal and transverse protection plates 33 and 36. One end of the torsion spring 35 is fixedly connected to the inner wall of the right side of the bottom end of the cylindrical shell 31, and the other end of the torsion spring 35 is fixedly connected to the rear surface of the top right end of the protection plate 33. Thread grooves 34 are formed on the outer wall of the detection tube 2. The thread grooves 34 are adapted to the inner wall of the ring 32 and have a certain up-and-down self-locking property to ensure the stability when the ring 32 is connected to the thread grooves 34. And there are two groups of thread grooves 34. One group is for limiting the ring 32 when the protection plate 33 and the protection plate 36 are closed, and the other group is for limiting when the protection plate 33 and the protection plate 36 are opened. The inner wall of the thread groove 34 is threadedly connected to the ring 32. The lower surface of the ring 32 is rotatably connected to the upper surface of the cylindrical shell 31. The inner wall of the ring 32 slides on the outer wall of the detection tube 2. The cylindrical shell 31 can only slide linearly upward or downward on the outer wall of the detection tube 2. The protection plate 36 slides on the inner wall of the left side of the bottom end of the cylindrical shell 31. A sealing groove 38 is formed on the right surface of the protection plate 36. A sealing strip 37 is fixedly connected to the left surface of the protection plate 33. The left surface of the sealing strip 37 is an arc surface and is made of rubber material with a certain elasticity to ensure that the protection plate 33 and the protection plate 36 can be opened and closed smoothly. The sealing strip 37 contacts the inner wall of the sealing groove 38.
[0028] Refer to Figure 2 - Figure 3 , Figure 5, a connecting plate 45 is elastically connected to the inner wall of the fixed block 42 through a spring 46. The spring 46 has a certain elasticity and always pushes the connecting plate 45 to move to the right through its own elasticity, ensuring the stability of the limit of the limit rod 47. The rear end of the connecting plate 45 is slidably connected to the inner wall of the fixed block 42, and the front end of the connecting plate 45 is slidably connected to the inner wall of the sliding block 43. One end of the spring 46 is fixedly connected to the inner wall of the fixed block 42, and the other end of the spring 46 is fixedly connected to the left surface of the connecting plate 45. A push block 44 is fixedly connected to the right surface of the rear end of the connecting plate 45. By pushing the push block 44, the movement of the connecting plate 45 can be controlled, so that the movement of the limit rod 47 can be controlled, ensuring that the limit of the limit rod 47 can be smoothly released. The push block 44 penetrates and is slidably connected to the right surface of the fixed block 42. A limit rod 47 is fixedly connected to the front surface of the connecting plate 45. The limit rod 47 is adapted to the groove, ensuring the stability of the limit. The limit rod 47 penetrates and is slidably connected to the right surface of the sliding block 43. Multiple groups of grooves are provided on the inner wall of the chute 5, and multiple groups of grooves are provided as the limit points of the elastic block 41 at different heights. The limit rod 47 contacts the inner wall of the groove.
[0029] Working principle: When using this portable pH meter and it is necessary to open the first protective plate 33 and the second protective plate 36, the ring 32 can be rotated. Since the ring 32 is threadedly connected to the thread groove 34 on the outer wall of the detection tube 2, the rotation of the ring 32 will drive the cylindrical shell 31 to slide upward on the outer wall of the detection tube 2 until the ring 32 is disengaged from the thread groove 34. At this time, the cylindrical shell 31 can be directly pulled upward by the ring 32 to slide until the ring 32 moves to the bottom side of another thread groove 34. At this time, the ring 32 can be rotated to make it threadedly connected to another thread groove 34 to ensure stability. When the cylindrical shell 31 moves upward, the detection tube 2 will push open the first protective plate 33 and the second protective plate 36. The first protective plate 33 and the second protective plate 36 will rotate respectively around the centers of the rotating rods 39 connected to them, and at the same time, the torsion spring 35 will be twisted and deformed, and the sealing strip 37 will also smoothly disengage from the inner wall of the sealing groove 38 through its own elasticity. In this way, the first protective plate 33 and the second protective plate 36 can be smoothly opened. When closing, the connection between the ring 32 and another thread groove 34 is released, and the cylindrical shell 31 is pushed downward. The torsion spring 35 will close the first protective plate 33 and the second protective plate 36 through its own elasticity, which is very convenient.
[0030] In terms of the fixed component, the sliding block 43 can slide within the sliding groove 5 on the rear surface of the housing 1. When it is necessary to fix the pH meter, the bottom end of the elastic clamping block 41 is pulled open and clamped onto an object. The connecting plate 45 elastically connected by a spring 46 inside the fixing block 42 always pushes the limiting rod 47 to contact the groove on the inner wall of the sliding groove 5 to limit the position of the sliding block 43. When it is necessary to adjust the position of the elastic clamping block 41, push the push block 44 to drive the connecting plate 45 to move, so that the limiting rod 47 disengages from the groove to release the limit. After adjusting the position, loosen the push block 44, and the spring 46 will push the limiting rod 47 to contact the corresponding groove again for limiting.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
