[0022] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following provides a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0023] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.

[0025] Embodiment 1, referring to Figures 1 to 4 , which is the first embodiment of the present utility model. This embodiment provides a board fixing structure. By setting the limiting groove 101a-11, the pressing block 201a is locked to prevent the board connected to the pressing block 201a from accidentally falling off.

[0026] Specifically, the installation component 100 includes a fixing member 101 and an assembling member 102 movably disposed on the outer wall of the fixing member 101; the clamping component 200 includes a movable member 201 and a positioning member 202 movably disposed on the outer wall of the movable member 201. Among them, the fixing member 101 includes a bottom plate 101a, a slope 101a-1 is provided on the outer wall of the bottom plate 101a, and a limiting groove 101a-11 is opened on the outer wall of the slope 101a-1. The movable member 201 includes a pressing block 201a disposed outside the bottom plate 101a, and the pressing block 201a is movably matched with the limiting groove 101a-11.

[0027] Among them, the connecting plate 102a is the board that needs to be fixed on the device.

[0028] Among them, the limiting groove 101a-11 is opened at one end of the slope 101a-1, and the thickness of the part of the pressing block 201a that is pulled by hand at one end is slightly smaller than the limiting groove 101a-11, so that the limiting groove 101a-11 can lock the pressing block 201a.

[0029] Preferably, the assembling member 102 includes a connecting plate 102a, and a first through hole 102a-1 is penetrated through the outer wall of the connecting plate 102a.

[0030] Preferably, the positioning member 202 includes a first boss 202a disposed on the connecting plate 102a, and a clamping hole 202a-1 is provided on the outer wall of the first boss 202a.

[0031] Preferably, a second boss 202b is provided on the outer wall of the first boss 202a, and a shaft hole 202b-1 is provided on the outer wall of the second boss 202b.

[0032] Wherein, the apertures of the first through hole 102a-1 and the clamping hole 202a-1 are the same, and the first boss 202a and the second boss 202b are preferably arranged in a cylindrical shape.

[0033] Wherein, the first boss 202a and the second boss 202b are symmetrically arranged on both sides of the connecting plate 102a and are coaxial with the first through hole 102a-1. As Figure 3 shown, the first boss 202a, the second boss 202b and the connecting plate 102a are integrally connected; when it is necessary to lock the connecting plate 102a on the bottom plate 101a, the pressing block 201a is inserted into the limiting groove 101a-11 to complete the locking; the pulled end of the pressing block 201a is preferably arranged in a cylindrical shape and has a diameter larger than that of the second boss 202b.

[0034] In summary, the staff member pulls the pressing block 201a to make the pressing block 201a and the second boss 202b perform a movable fit. When it is necessary to install the connecting plate 102a on the bottom plate 101a, only the pressing block 201a needs to be inserted into the limiting groove 101a-11 to complete the locking, and the operation of the staff member is very convenient.

[0035] Embodiment 2, referring to Figures 1 to 4 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that by passing the pressing block 201a through the bottom of the bottom plate 101a and placing it into the large second through hole 101a-3, when moving along the notch 101a-2 to the slope 101a-1, pulling the pressing block 201a makes the pressing block 201a pass through the slope 101a-1 and then move along the notch 101a-2. When the pressing block 201a moves to the small second through hole 101a-3, the pressing block 201a is clamped into the limiting groove 101a-11 to prevent the board from falling off accidentally.

[0036] Specifically, a notch 101a-2 is opened on the outer wall of the bottom plate 101a, and second through holes 101a-3 are provided at both ends of the notch 101a-2.

[0037] Preferably, a connecting shaft 201b is provided on the outer wall of the pressing block 201a, and an elastic member 201c is sleeved on the outer wall of the connecting shaft 201b.

[0038] Preferably, a convex ring 201b-1 is provided at one end of the connecting shaft 201b.

[0039] Preferably, the convex ring 201b-1 is in movable fit with the clamping hole 202a-1.

[0040] Preferably, the shaft hole 202b-1 is movably fitted with the connecting shaft 201b.

[0041] Preferably, a connecting ring 201a-1 is provided on the outer wall of the pressing block 201a, and the connecting ring 201a-1 is movably fitted with the second boss 202b.

[0042] Among them, the second through holes 101a-3 are of different sizes. The diameter of the larger second through hole 101a-3 is greater than the diameter of the cylinder at the hand-held end of the pressing block 202a, so that the pressing block 201a can pass through from the bottom and be placed into the larger second through hole 101a-3. As Figure 2 shown, the larger second through hole 101a-3 is provided on the left side of the notch 101-2, and the smaller second through hole 101a-3 is provided on the right side of the notch 101a-3. The width of the notch 101-2 is slightly greater than the outer diameter of the connecting ring 201a-1, so that the pressing block 201a can move in the notch 101a-2; the elastic member 201c is preferably set as a compression spring, and the elastic member 201c is arranged in the clamping hole 202a-1.

[0043] Furthermore, the operator inserts the pressing block 201a into the bottom plate 101a from the larger second through hole 101a-3. The pressing block 201a moves along the notch 101a-2 and moves towards the smaller second through hole 101a-3 at the other end of the notch 101a-2. During the movement, when passing through the slope surface 101a-1, the operator pulls the pressing block 201a outwards. At this time, the elastic member 201c sleeved on the connecting shaft 201b is compressed, and the inner wall of the connecting ring 201a-1 is temporarily separated from the second boss 201b. The pressing block 201a moves a certain distance relative to the second boss 202b, so that the pressing block 201a can pass through the slope surface 101a-1. After passing through the slope surface 101a-1, the operator releases the pressing block 201a, the elastic member 201c rebounds, the pressing block 201a resets, and the connecting ring 201a-1 is sleeved on the second boss 202b. Then continue to move the pressing block 201a along the notch 101a-2. When the pressing block 201a reaches the smaller second through hole 101a-3, it is limited. At this time, move the pressing block 201a slightly towards the slope surface 101a-1, and snap the pressing block 201a into the limiting groove 101a-11 for fixation, so that the connecting plate 102a will not fall off easily.

[0044] In summary, when the staff installs the connecting plate 102a, they only need to operate on the pressing block 201a. Put the pressing block 201a into the large second through hole 101a-3, and move the pressing block 202a along the notch 101a-2. When it moves to the slope 101a-1, pull the pressing block 201a so that the pressing block 201a can pass through the slope 101a-1. When the pressing block 201a moves to the small second through hole 101a-3, then snap the pressing block 201a into the limiting groove 101a-11 to lock the entire connecting plate 102a. This process can effectively prevent the accidental detachment of the connecting plate 102a, and the entire operation does not require additional tools, saving the assembly time of the staff.
