Abstract
The utility model provides a lifting device of projectors, comprising a housing for holding the projector. A platform is arranged in the housing, on which the projector can be put. A forficiform lifting support is arranged between the platform and the bottom of the housing. A tension spring is arranged between the two legs of the forficiform lifting support, which is used for sending up the forficiform lifting support. A locating mechanism is arranged between the platform and the housing, which is used for making the forficiform lifting support in a compressing position. The lifting device of projector has the advantages of simple mechanical structure, easy manufacture, convenient use, high reliability and convenient operation.
Description
Technical field
The utility model relates to projector, and particularly a kind of projector of can realizing rises the projector jacking gear that uses and pack up preservation fast fast.
Background technology
General engineering truck or communication vehicle need carry projector equipment, and common on the market family expenses or teaching often need to be fixed on the body of wall, also need punching for this reason, and therefore such mounting means also is not suitable for the installation of vehicle-mounted projector.The use of at present vehicle-mounted projector all is to be fixed in the interior drawer of car, perhaps uses the electric up-down platform to be fixed.Both shortcomings are: the former uses is trouble, also needs to install operations such as power lead temporarily; The latter is because use is electronic, so use is simple relatively, but needs motor is installed, and operational reliability is not high, and has noise.
Summary of the invention
Goal of the invention: the utility model provides a kind of projector jacking gear at the deficiencies in the prior art.
Technical scheme: the utility model provides a kind of projector jacking gear, and it comprises the casing that can hold projector, is provided with the platform that is used to place projector in the casing; Be provided with the scissor lifting support between the bottom of platform and casing, between two legs of scissor lifting support, be provided with the back-moving spring that the scissor lifting support is risen, between platform and casing, be provided with the detent mechanism that the scissor lifting support is in compression position.
Described detent mechanism is made of the L shaped bayonet lock of band collar and the back-moving spring that is enclosed within on the bayonet lock, and L shaped bayonet lock can snap in the pin-and-hole of cabinet wall under the effect of back-moving spring.
The bottom of described casing is provided with spacing pedestal, two lower support pin of scissor lifting support are supporting surface with spacing pedestal, can guarantee the stability of projector jacking gear integral body like this, can limit the open stroke of feet of scissor lifting support again, thus the rise height of control scissor lifting support.
For the scissor lifting support is risen and reduce more flexible, the friction force that contacts with ground when reducing the lifting of scissor lifting support, the supporting leg of described scissor lifting support is provided with roller.
Beneficial effect: projector jacking gear described in the utility model, physical construction is simple, is convenient to make and use, the reliability height, easy to operate.The utility model only need overcome spring when packing up use pulling force gets final product, so do not need very big strength just can be fixed, and when rise is used, only need to press downwards, push bayonet lock aside, the whole erection platform will rise under the effect of spring automatically.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the utility model detent mechanism structural drawing.
Embodiment
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
As shown in Figure 1, the projector jacking gear of a kind of embodiment of the utility model, it comprises the casing 1 that can hold projector, is provided with the platform 2 that is used to place projector in the casing 1.Platform 2 is connected with two upper support legs of scissor lifting support 3.The bottom of described casing 1 is provided with spacing pedestal 6, and two lower support legs of scissor lifting support 3 are provided with roller 7 and are supporting surface with spacing pedestal 6, and are provided with spring 4 between two supporting legs of scissor lifting support 3.Between platform 2 and casing 1, be provided with the detent mechanism that scissor lifting support 3 is in compression position.
As shown in Figure 2, described detent mechanism is made of the L shaped bayonet lock 5 of band collar and the spring 8 that is enclosed within on the bayonet lock 5, and L shaped bayonet lock 5 can snap in the pin-and-hole of casing 1 inwall.
The utility model utilizes the pulling force between the spring 4 between the feet that scissor lifting support 3 is risen automatically, and when platform 2 did not need to rise, bayonet lock 5 was stuck in the pin-and-hole of casing 1 inwall.During use the mounting platform 2 of projector is pressed downwards, dialled tight bayonet lock 5 to the inside, whole erection platform 2 will rise under the effect of spring 4; When packing up, only need to press platform 2 downwards, when platform 2 moved down into the fixed position, the bayonet lock 5 of platform snapped in the pin-and-hole of casing 1 inwall under the effect of spring 8 pulling force automatically.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
