Referring to fig. 1 to 3, a fan frame 100 provided by the present application includes at least two frame bodies 10 connected in series and a locking structure 20 disposed on a circumferential side wall of the frame body 10. Here, the serial connection is a case where the housing bodies 10 are sequentially stacked in the blowing direction, but of course, the number of housing bodies may be increased according to actual needs, for example, two or more housing bodies may be stacked in the blowing direction. The frame bodies 10 have a joint end surface 10a for serial connection, the locking structure 20 includes a locking portion 21 disposed on a first frame body 10 and a locking mating portion 22 disposed on an adjacent second frame body 10 and adapted to the locking portion 21, the locking portion 21 and/or the locking mating portion 22 protrude from the joint end surface 10a, and the locking portion 21 and the locking mating portion 22 are locked or unlocked when the two adjacent frame bodies 10 rotate around a central axis. It can be understood that, when the plurality of fan housings 100 are used in combination, except that the housing bodies 10 at two ends have only one combination end surface 10a, the other housing bodies 10 have two opposite combination end surfaces 10a, and the combination end surfaces 10a of two adjacent housing bodies 10 are in contact when connected in series. And, the frame body 10 of both ends is provided with only the locking part 21 or the locking fitting part 22, and the remaining frame body 10 is provided with two locking parts 21; alternatively, two lock engagement portions 22; or one locking portion 21 and one locking mating portion 22. And, in order to ensure the connection between two adjacent frame bodies 10, the locking portion 21 needs to protrude from the connecting end surface 10a to ensure a connecting space with the locking mating portion 22. Of course, the lock engagement portion 22 may protrude from the joint end surface 10a, or both may protrude from the joint end surface 10 a. At the same time, it is emphasized that: when two adjacent frame bodies 10 are combined, the locking portion 21 and the locking engagement portion 22 are locked or unlocked by rotating around their own central axes. Here, the locking structure 20 is a structure that is easily detachable, that is, the locking portion 21 and the locking engagement portion 22 can be connected and combined by a connection method such as a snap, a buckle, or the like.

In the fan housing 100 of the present invention, when the adjacent second housing bodies 10 are connected in series, the joint end surfaces 10a of the second housing bodies 10 are in contact or abutting contact with each other, and the locking or unlocking of the locking portion 21 and the locking engagement portion 22 is realized by rotating around their own central axes, for example, when the housing bodies 10 rotate clockwise around an axis, the locking portion 21 and the locking engagement portion 22 are locked, and when the housing bodies 10 rotate counterclockwise around an axis, the locking portion 21 and the locking engagement portion 22 are unlocked. Therefore, the whole series connection and combination process is quick and efficient, and the operation efficiency is greatly improved.

Referring to fig. 1 to 3, in an embodiment, the fan frame 100 includes a positioning structure 30, the positioning structure 30 includes a positioning column 31 disposed on the combining end surface 10a of the first frame body 10 and a positioning slot 32 disposed on the combining end surface 10a of the adjacent frame body 10, and the positioning column 31 can slide in the positioning slot 32 when the adjacent two frame bodies 10 rotate around the central axis. It can be understood that since the joint end surfaces 10a of two adjacent frame bodies 10 are smooth, the positioning of the locking portions 21 and the lock fitting portions 22 is not facilitated during the pivoting of the frame bodies 10. Therefore, the positioning columns 31 and the positioning grooves 32 are arranged on the joint end surface 10a to ensure that no relative sliding exists between two adjacent frame bodies 10 in the radial direction, so that the locking part 21 can be accurately connected with the locking matching part 22 in the process of rotating along with the frame bodies 10, and the impact or damage to the locking part 21 or the locking matching part 22 protruding out of the joint end surface 10a caused by the relative sliding of the adjacent second frame bodies 10 in the radial direction can be avoided.

Referring to fig. 1, in one embodiment, the frame body 10 is cylindrical. Because frame body 10 accessible locking structure 20 direct dismouting need not to use the screw, then frame body 10 need not to set up the prism that supplies the screw to wear to establish, and whole volume is littleer.

Example one

Referring to fig. 1 to 3, in the present embodiment, the locking portion 21 includes a fastening plate 21a, a fastening hole 21b is formed on the fastening plate 21a, the fastening plate 21a protrudes from the combining end surface 10a, and the locking engagement portion 22 is a convex fastener. It can be understood that the positions of the fastening hole 21b on the fastening plate 21a protruding from the combining end surface 10a of the frame body 10 and the position of the protruding buckle on the other frame body 10 are corresponding, that is, when two adjacent frame bodies 10 rotate around the shaft, the fastening plate 21a and/or the protruding block translate on the circumferential side wall of the frame body 10, and finally, the protruding buckle is fastened into the fastening hole 21b of the fastening plate 21 a. Of course, when the frame body 10 rotates reversely, the convex buckle is released from the clamping hole 21 b.

Preferably, referring to fig. 4, the male buckle has a lead-in slope 22a for assisting sliding into the snap hole 21 b. It can be understood that, in order to smoothly and rapidly enter the fastening hole 21b, the convex buckle is provided with a guiding inclined surface 22a, so that the outline of the convex buckle is in a structural form with one end lower and the other end higher, which facilitates the installation of the convex buckle.

Optionally, referring to fig. 4, the male buckle further has a guiding-out inclined surface 22b for assisting in sliding out of the fastening hole 21b, and the guiding-out inclined surface 22b is in transition with the guiding-in inclined surface 22a, so that the outline of the male buckle is in a structural form with two low ends and a high middle, and thus, when the frame body 10 rotates reversely, the male buckle can smoothly slide out of the fastening hole 21b under the guidance of the guiding-out inclined surface 22 b.

Referring to fig. 2, in an embodiment, the locking portion 21 further includes an extending plate 21c disposed on the circumferential side wall of the frame body 10, and an end of the fastening plate 21a facing away from the structural end surface is connected to the extending plate 21 c. Here, the extending plate 21c serves to increase the coupling area of the locking plate 21a and the housing body 10, thereby improving the connection stability with the housing body 10.

Example two

Referring to fig. 5, in the present embodiment, the locking portion 21 is a first engaging arm, the locking mating portion 22 is a second engaging arm, and the first engaging arm protrudes from the combining end surface 10 a; or the second clamping arm protrudes out of the combination end surface 10 a; alternatively, the first and second snap arms may protrude from the coupling end surface 10 a. It can be understood that the first snap arms and the second snap arms can be overlapped in a staggered manner in the circumferential direction of the frame body 10, and then the connection is achieved, that is, the two adjacent frame bodies 10 cannot be separated in the axial direction. When separation is needed, the frame body 10 continues to rotate around the shaft or reversely rotate, so that the first clamping arm and the second clamping arm do not have overlapped parts, and then the two frame bodies 10 can be separated.

Specifically, referring to fig. 5, the first clamping arm includes a first clamping section 21d, a second clamping section 21e and a third clamping section 21f connected in sequence, the first clamping section 21d is connected to the frame body 10, and the third clamping section 21f is used for clamping and connecting to the second clamping arm. It can be understood that the first clamping section 21d extends out of the sidewall of the frame body 10, so that a certain distance is formed between the second clamping section 21e and the sidewall of the frame body 10 and between the third clamping section 21f and the sidewall of the frame body 10, so as to provide a position space for being fastened with the second clamping arm, and meanwhile, the second clamping section 21e functions to extend the third clamping section 21f into the joint end surface 10a, so as to meet the position requirement for being fastened with the second clamping arm. The third clamping section 21f may be bent toward the frame body 10 or bent away from the frame body 10, so as to form an end surface fastened with the second clamping arm.

Specifically, referring to fig. 5, the second clamping arm includes a fourth clamping section 22c and a fifth clamping section 22d connected in sequence, the fourth clamping section 22c is connected to the frame body 10, and the fifth clamping section 22d is clamped and connected to the third clamping section 21 f. It can be understood that the fifth clamping section 22d can be bent away from the frame body 10 or bent toward the frame body 10, so as to form an end surface capable of being buckled with the third clamping section 21 f.

Specifically, referring to fig. 5, the third clamping section 21f and/or the fifth clamping section 22d are provided with a protrusion structure 22f for maintaining the connection stability of the two. It can be understood that, when the third engaging section 21f and the fifth engaging section 22d are engaged, a gap exists between them, and therefore, the two corresponding frame bodies 10 are easy to be loosened in the axial direction, and thus, the connection stability between them is low. In order to solve the above problem, the protrusion structure 22f can reduce the gap therebetween, thereby preventing the looseness between the frame bodies 10. Specifically, protruding structure 22f is the colloid that can deform, utilizes the deformability and the high coefficient of friction of colloid, can fill the space between third joint section 21f and the fifth joint section 22d effectively, simultaneously, avoids third joint section 21f and fifth joint section 22d not to take place relative slip after the lock.

The present application further provides a fan, which includes a plurality of the fan frame bodies 100.

The fan provided by the utility model can be quickly assembled and disassembled on the basis of the fan frame body 100, thereby greatly improving the working efficiency.

It should be understood that the fans may be combined by a variable number of fan housings 100, for example, by combining two fan housings 100 or by combining more than two fan housings 100 according to actual use requirements.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
