1. Field of the Invention
The present invention relates to a support with a locking device, and more particularly to a support with a locking device for a barbecue, with which it is easy to adjust the height of a barbecue grill cover to control the temperature.
2. Description of the Related Art
A barbecue has a gas burner, a grill and a cover. The cover is mounted over the grill to concentrate the heat and accelerate the cooking process.
However, the cover can only be completely opened or completely closed. Hence, when cooking, the grill is either completely exposed or completely covered such that it is difficult to control the temperature.
Therefore, the invention provides a support with a locking device for a barbecue grill cover to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a support with a locking device for a barbecue grill cover with which is easy to adjust the height of the cover to control the temperature.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The base plate (21) has a bracket (211) mounted on a lower sidewall thereof. A channel (210) is formed between the bracket (211) and the lower sidewall of the base plate (21). The channel (210) faces downward and has two open ends. Multiple parallel slots (212) are transversely defined in the base plate (212).
The adjusting plate (22) has a handle (221) mounted at a first end thereof and an up-turned end (222) formed at a second end thereof. A slit (220) is defined transversely in a middle portion of the adjusting plate (22) and has a larger width than the base plate (21). Two ears (223) are respectively formed at two opposite sides of the adjusting plate (22) and extend upwards. Corresponding through holes are defined in each ear (223). A pin (224) is inserted through the through holes in the ears (223).
The locking plate (23) has a V-shaped cross section forming two wings. A first wing has a bent locking tab (230) formed at a free end and a second wing has a bent thumb tab (231) formed at a free end.
In assembly, the base plate (21) is inserted into the slit (220) of the adjusting plate (22) so that the adjusting plate (22) can be moved longitudinally along the base plate (21). The locking plate (23) is mounted on the adjusting plate (22) between the ears (223). The pin (224) is inserted into the through holes of the ears (223) over the locking plate (23) so that the locking plate (23) can pivot about the pin (224). The spring (24) is mounted between the adjusting plate (22) and the thumb tab (231) to bias the locking plate (23). The locking tab (230) is inserted into and securely connected to a slot (212).
In another embodiment, the spring (24) can be mounted between the adjusting plate (22) and the wing of the locking plate (23) with the locking tab (230) thereby the wing is pulled downward by the spring.
