Description

Vertical fan structure

The present invention relates to a frame structure of a vertical electric fan, in particular, the frame body has a function of folding, and the frame body can be fixed at an unfolding angle to form a positioning.

According to the structure of a general vertical fan, a telescopic function bracket is arranged on a large area of the base, and a motor body and a blade body driven by the motor body are assembled on the bracket. In use, the length of the bracket can be flexibly adjusted to change the height of the fan blade air supply.

However, since the large-area base will occupy more space, it is not only unfavorable for transportation and carrying, but also extremely inconvenient in collecting. For this reason, some people have developed a vertical fan with a folding function, for example, the Republic of China patent number M265542 The utility model relates to an electric rack with a telescopic support rod, which has a telescopic bracket, and a fan body and a base are respectively pivotally connected at two ends thereof, so as to pivot the base and the bracket relative to each other, thereby saving storage space and carrying convenience. the goal of.

However, there are still some shortcomings in the use of the above-mentioned previous cases to be improved. The main reasons are:

1. Although the front case allows the base and bracket of the vertical fan to pivot relative to each other for easy carrying or unfolding, the previous case does not disclose how the base is used when the electrical frame is deployed. The stent is fixed at an angle of deployment and lacks a positioning mechanism so that the product is not practical.

2. Furthermore, since the bracket needs to bear the load of the motor body and the blade body, if the angle of deployment between the fixed base and the bracket is not sure, it will be easy to shake and vibrate during use.

Therefore, in order to improve the lack of a fixed angle of the vertical fan, the creator is devoted to research and develops a frame structure of a vertical fan, comprising: a body comprising a bracket and a body. The bracket and the base body are configured to be folded or unfolded; a positioning component is disposed on the body, and includes a first positioning portion and a pair of second positioning portions that should be the first positioning portion, the first positioning portion is configured On the bracket, the second positioning portion is disposed on the base body to engage the first positioning portion and the second positioning portion with each other when the bracket is unfolded relative to the base body.

Further, the second positioning portion includes a pair of clamping arms and two opposite engaging surfaces, and the pair of clamping arms define an engaging space to be correspondingly sleeved on the first positioning portion, and the engaging surface is in the The clamping arm faces a side of the engaging space to correspondingly engage the first positioning portion.

Further, the first positioning portion is a circular tubular shape, and the engaging surface of the second positioning portion is curved to correspondingly fit the peripheral edge of the first positioning portion.

Further, the aforementioned clamping arm is a spring piece.

Further, the second positioning portion further includes a connecting surface, an opening opposite to the connecting surface, and a guiding portion connecting the two engaging surfaces, and the clamping arm is facing the opening by the connecting surface The guide portion is extended to form.

Further, the positioning assembly further includes a pair of protective sleeves, and the protective sleeve is sleeved on the clamping arms.

Further, the body further includes a pivoting assembly including a first pivoting portion and a second pivoting portion pivotally connected to each other, the first pivoting portion being disposed on the bracket, the second The pivoting portion is disposed on the base body such that the seat body and the bracket are pivotable relative to each other.

Further, the body further includes a pivoting assembly including a first pivoting portion and a second pivoting portion pivotally connected to each other, the first pivoting portion being disposed on the bracket, and the first pivoting portion is disposed on the bracket The two pivoting portions are disposed on the second positioning portion.

Compare the efficacy of the prior art:

1. In this case, the positioning component is used to stabilize the angle between the fixed seat and the bracket to form a positioning, thereby avoiding the shaking vibration during use or collapsing when the bracket is subjected to excessive load to improve the stability of the structure.

2. In this case, when the force is applied to pull the bracket to the seat, the bracket will be disengaged from the second positioning portion, and the bracket and the seat body can be folded relatively to achieve the purpose of saving the storage space, and the convenience of product transportation and carrying is increased.

3. The positioning component of the present case is provided with a protective sleeve on the clamping arm sleeve to reduce the wear caused by the clamping of the clamping arm facing the bracket, and to improve the fitting effect of the engaging surface of the clamping arm and the circumference of the bracket, avoiding the bracket Shaking.
