DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] See also Figures 1 to 5 The embodiment of the utility model provides a mounting structure of a panel 1 and a housing 2, which is used to mount the panel 1 on the housing 2, including:

[0029] The first installation point includes a protruding card 3 formed on the panel 1 and a card slot 4 formed on the housing 2, and the protruding card 3 is detachably arranged in the card slot 4;

[0030] The second installation point includes a latch 6 formed on the panel 1 and a latch hole 7 formed on the housing 2, wherein the latch 6 is detachably disposed in the latch hole 7;

[0031] The third installation point includes a lock buckle 9 slidably arranged on the panel 1 and a lock-off chamber 8 arranged on the shell 2. Under the action of external force, the lock buckle 9 has a locked state extending into the lock-off chamber 8 and an unlocked state extending out of the lock-off chamber 8. In the locked state, the lock buckle 9 abuts against the lock-off chamber 8 to limit the movement of the panel 1. In the unlocked state, the lock buckle 9 is separated from the lock-off chamber 8 to release the limit fit between the panel 1 and the shell 2.

[0032] Among them, the first installation point is set along the front-to-back direction, the second installation point is set along the top-to-bottom direction, and the third installation point is set along the left-to-right direction.

[0033] In this embodiment, in order to install the panel 1 on the shell 2 of the hot air blower, three installation points are formed between the panel 1 and the shell 2. The first installation point includes a convex card 3 provided on the panel 1 and a card slot 4 provided on the shell 2 and adapted to the convex card 3. The convex card 3 can be detachably embedded in the card slot 4 of the shell 2, thereby realizing the positioning and preliminary fixation of the panel 1 along the front and rear directions. The second installation point includes a latch 6 provided on the panel 1 and a latch hole 7 provided on the shell 2. The latch 6 is also designed to be detachable and can be smoothly inserted into the latch hole 7 of the shell 2, thereby ensuring the stable connection of the panel 1 in the up and down directions and enhancing the stability of the overall structure. The third installation point includes a lock buckle 9 slidably provided on the panel 1 and a corresponding lock buckle 9 chamber on the shell 2. When external force is applied, the lock buckle 9 can slide into or out of the lock chamber 8 to realize the conversion between the two states. In the locked state, the lock buckle 9 slides into the lock chamber 8, tightly abutting against it. In this state, the panel 1 cannot be separated from the shell 2. With the cooperation of the first installation point and the second installation point, the panel 1 cannot move forward and backward, up and down, and under the locking of the lock buckle 9, the panel 1 cannot move left and right. The three installation positioning points are arranged along the front and back, up and down, and left and right directions respectively, forming a three-dimensional space. A stable installation structure ensures that the installation between the panel 1 and the shell 2 is both firm and reliable; in the unlocked state, the lock buckle 9 slides out of the lock chamber 8, so that the panel 1 can move freely. After the unlocked state is released, the panel 1 is first separated from the card slot 4 by the convex card 3, and then the pin 6 is separated from the pin hole 7, and then it can be separated from the shell 2, which is convenient for the user's disassembly operation, and is also convenient for operation and adjustment. It is suitable for use scenarios that require frequent disassembly and assembly or precise alignment. It not only improves the convenience of installation, but also enhances the stability and durability of the overall structure.

[0034] The convex card 3 is provided with a first inclined surface 301 and a second inclined surface 302 in a mirror image, and the first inclined surface 301 and the second inclined surface 302 are inclined inward from one end of the convex card 3 to the other end thereof;

[0035] The card slot 4 is mirror-imaged with a third inclined surface 401 and a fourth inclined surface 402. From the closed end of the card slot 4 to the open end thereof, the third inclined surface 401 and the fourth inclined surface 402 are inclined outwardly for cooperating with the first inclined surface 301 and the second inclined surface 302 respectively.

[0036] In this embodiment, an inclined surface is respectively provided at both ends of the convex card 3, namely a first inclined surface 301 and a second inclined surface 302, and the first inclined surface 301 and the second inclined surface 302 gradually incline inward from one end of the convex card 3 to the other end, so that the convex card 3 can be guided by the inclined surface during the insertion process of the card slot 4, and it is easier to align and slide into place. At the same time, as the insertion depth increases, the mutual squeezing between the inclined surfaces will generate an inward clamping force, which is conducive to a tight fit during fixation and improves the stability of the connection. Correspondingly, matching inclined surfaces are also designed inside the card slot 4, namely a third inclined surface 401 and a fourth inclined surface 402, and the third inclined surface 401 and the fourth inclined surface 402 are inclined outward from the closed end to the open end of the card slot 4, so that when the convex card 3 is inserted, its inclined surface and the inclined surface in the card slot 4 bite each other to form a mechanical locking effect between the inclined surfaces, which not only facilitates the smooth sliding of the convex card 3, but also can strengthen the locking of the convex card 3 and the card slot 4 through the reverse inclination angle of the inclined surface after it is fully inserted to prevent accidental disengagement. Furthermore, the third inclined surface 401 and the fourth inclined surface 402 are elastic cards 5; the elastic card 5 can provide elastic force and self-adjustment function. When the convex card 3 is inserted into the card slot 4, when interacting with the first inclined surface 301 and the second inclined surface 302, the elastic card 5 will be slightly deformed due to pressure, helping the convex card 3 to slide into place more smoothly. When the convex card 3 is fully embedded, the elastic card 5 will press the convex card 3 due to its own restoring force (elastic recovery) to form a tighter and stronger connection. When the convex card 3 is separated from the card slot 4, under the action of external force, the elastic card 5 is deformed, and the mutual guidance of the first inclined surface 301, the second inclined surface 302, the third inclined surface 401 and the fourth inclined surface 402 enables the convex card 3 to be smoothly separated from the card slot 4.

[0037] The panel 1 is provided with an installation compartment 103 arranged in an up-down direction, and the lock buckle 9 is slidably disposed in the installation compartment 103 .

[0038] In this embodiment, an installation bin 103 arranged along the up and down direction is provided on the panel 1. The installation bin 103 is used to accommodate and guide the sliding movement of the lock buckle 9. By arranging the lock buckle 9 in the installation bin 103, a guide and support are provided for the sliding movement of the lock buckle 9, ensuring its smoothness and precision during the sliding process. The installation bin 103 provides precise guidance for the sliding trajectory of the lock buckle 9, ensuring that the lock buckle 9 can accurately extend into or exit the lock bin 8, avoiding misoperation or jamming. The installation bin 103 forms a certain protection for the lock buckle 9, reduces the direct impact or wear on it by external factors, and prolongs the service life of the lock buckle 9.

[0039] The lock buckle 9 includes a movable block 901 and a limit block 902 connected to each other. The movable block 901 is slidably disposed in the installation chamber 103 so that the limit block 902 extends into or out of the lock chamber 8.

[0040] In this embodiment, the lock buckle 9 is composed of two connected parts: a moving block 901 and a limit block 902. The moving block 901 can be slidably installed in the installation bin 103 on the panel 1. By moving the moving block 901, the limit block 902 connected to it can be driven to slide up and down along the guide of the installation bin 103, so that the limit block 902 can be smoothly extended into the lock bin 8 on the shell 2 when needed, or withdraw from the lock bin 8.

[0041] The moving block 901 is provided with a buckle 903 , and the buckle 903 is at least partially protruded outside the installation chamber 103 .

[0042] In this embodiment, a handle 903 is provided on the movable block 901, which is at least partially protruding from the outside of the installation chamber 103. The existence of the handle 903 allows the user to easily grasp and operate the movable block 901 with fingers without complicated tools or going deep into the installation chamber 103, thereby pushing the limit block 902 to slide along the installation chamber 103 to complete the action of extending into or exiting the lock chamber 8.

[0043] The lock and ejection bin 8 is provided with a limiting groove 801 , both ends of which are connected in the up and down directions, and the groove opening is arranged toward the limiting block 902 .

[0044] In this embodiment, an L-shaped limit groove 801 is provided inside the lock chamber 8 of the shell 2. The limit groove 801 is through-through at both ends in the up and down directions, and its opening direction faces the limit block 902, so that when the limit block 902 extends into the lock chamber 8, it can be just embedded in the L-shaped limit groove 801, thereby being effectively positioned and restricted in two directions (up and down and depth), thereby improving the stability of the lock buckle 9 when locked.

[0045] The upper and lower ends of the limit block 902 are respectively provided with a first limit protrusion 10 and a second limit protrusion 11, and the panel 1 is provided with a first locking rib 101 and a second locking rib 102 at intervals. In the unlocked state, the second limit protrusion 11 is limitedly matched with the second locking rib 102. In the locked state, the first limit protrusion 10 is limitedly matched with the first locking rib 101.

[0046] In this embodiment, the upper and lower ends of the limit block 902 are respectively designed with a first limit protrusion 10 and a second limit protrusion 11, and the panel 1 is correspondingly provided with a first locking rib 101 and a second locking rib 102 at intervals, so that in different operating states, the limit block 902 can be accurately limited and matched with the locking rib on the panel 1; when in the unlocked state, the second limit protrusion 11 contacts and limits the second locking rib 102, ensuring that the limit block 902 can be temporarily fixed to a certain extent when it is not completely locked, preventing excessive sliding and facilitating operation and control. In the locked state, as the limit block 902 slides further, the first limit protrusion 10 and the first locking rib 101 achieve a tight limit fit. At this time, the limit block 902 is completely fixed in the lock bin 8, ensuring that the panel 1 and the shell 2 achieve the most stable connection state.

[0047] The first limiting protrusion 10 and the second limiting protrusion 11 are formed with a positioning groove 12 for accommodating the first locking rib 101 and the second locking rib 102 .

[0048] In this embodiment, the first limiting protrusion 10 and the second limiting protrusion 11 are provided with a positioning groove 12, and the positioning groove 12 is used to receive and match the first locking rib 101 and the second locking rib 102 on the panel 1. In the locked or unlocked state, the locking rib can not only contact with the surface of the limiting protrusion, but also be more accurately guided and fixed by the positioning groove 12, ensuring that the fit between the two is tighter and the position is more accurate.

[0049] This embodiment also proposes a hot air blower, which includes the installation structure of the panel 1 and the shell 2 mentioned above. The specific structure of the hot air blower refers to the above embodiment. Since this hot air blower adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
