The novel limit stoper of a kind of The Cloud Terrace
Technical field
The utility model belongs to the security protection field of video monitoring, the novel limit stoper of especially a kind of The Cloud Terrace.
Background technique
At present, the limit method of the The Cloud Terrace in the field of video monitoring adopts catch directly to contact with limit switch usually, realizes regulating the function of limit switch.But because catch self need occupy certain space, therefore, The Cloud Terrace can only be realized 355 degree rotations, can't reach 360 degree rotations, causes the adjustment range of The Cloud Terrace limited, influences the performance of product.Rotate for realizing that The Cloud Terrace 360 is spent, the mode that adopts is the installation conducting slip ring at present, but its cost is more expensive, and Economy is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple, safe and reliable, economical and practical, and the novel limit stoper of The Cloud Terrace of the index of can effectively enhancing product performance.
The utility model is achieved through the following technical solutions:
The novel limit stoper of a kind of The Cloud Terrace, it is characterized in that: mainly constitute by a pair of limit switch, a plectrum and the catch that are installed on the fixed plate, plectrum is installed between limit switch and the catch, two limit switch symmetries are installed on the both sides of plectrum one end, are shaped on the retaining head that can touch the plectrum the other end on the catch.
And, plectrum is installed by pillar, nut and torsion spring, column is installed on fixed plate threadably, on the column above the fixed plate, install plectrum, fixedly plectrum of nut is installed on column, overlapping torsion spring on the column between fixed plate and the plectrum, an end of this torsion spring is inserted on the fixed plate, and the other end of torsion spring is inserted on the plectrum.
Advantage of the present utility model and beneficial effect are:
1. the novel limit stoper of this The Cloud Terrace, play the intermediate transfer effect by set elasticity plectrum, its spacing angle is determined by the distance of set a pair of limit switch, thereby can realize 360 degree rotations of The Cloud Terrace easily, even surpass the above rotation of 360 degree, effectively improve the performance of product.
2. the utlity model has the function of The Cloud Terrace rotary stopper adjustable angle, and have simple in structure, reasonable in design, processing and easy for installation, cheap, advantage such as effectively safe in utilization.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The novel limit stoper of a kind of The Cloud Terrace, it mainly is made of a pair of limit switch 5, a sheet of plectrum 8 and the discoidal catch 9 that are installed on the fixed plate 6, plectrum is installed between limit switch and the catch, two limit switch symmetries are installed on the both sides of plectrum one end, and the catch outer rim is shaped on the retaining head that can touch the plectrum the other end.
The concrete mounting type of plectrum is: plectrum is installed by pillar 1, nut 2 and torsion spring 7, and column is installed on fixed plate threadably, installs plectrum on the column above the fixed plate, on the column on the plectrum nut is installed.Suit torsion spring on the column between fixed plate and the plectrum, an end of this torsion spring is inserted on the fixed plate, and the other end of torsion spring is inserted on the plectrum.Pillar one end is a worm structure, and the other end is that screw thread adds boss structure.Torsion spring is to be used for guaranteeing that plectrum when being vibrated, can not contact limit switch, guarantees that plectrum is in state of equilibrium.Plectrum one end has the bending structure.Two limit switch limit switches all are installed on the desired location of fixed plate with the thread connecting mode symmetry by screw 3, packing ring 4.
Catch is connected and rotates with axle or other part, catch rotate one week its retaining head of back contact with plectrum, the drive plectrum makes plectrum rotate around pillar, the plectrum the other end contacts with limit switch, reaches spacing purpose.When backward rotation, plectrum contacts with another limit switch, reaches spacing purpose.When the banking stop and the plectrum of limit switch is under the contactless state, plectrum is got back to reduction point under the effect of torsion spring.When design, adjust the mounting point of limit switch on fixed plate, or adjust the position of pillar on fixed plate, can realize 360 degree of The Cloud Terrace, or rotate above 360 degree.
