Abstract
A net height measuring device for ball games with nets comprises a base and a vertical ruler fixed to the base, wherein a vernier in sliding fit with the ruler is arranged on the ruler, two laser transmitters are arranged on the vernier and located at the same height, transmitting ends of the two laser transmitters are in the opposite directions, a locking mechanism is arranged between the ruler and the vernier, and the ruler and the vernier are fixed through the locking mechanism. When the net height measuring device is in use, firstly, the vernier is adjusted to the height needed by a ball net, the vernier is fixed through the locking mechanism, then, the laser transmitters are started, the two laser transmitters can emit red or blue visual laser beams towards the two sides, and the visual laser beams emitted by the two laser transmitters are located on the same horizontal line. Therefore, the heights of all the positions of the ball net can be measured at the same time through the visual laser beams on the same horizontal line, and whether the two ends and the center of the ball net are located on the same horizontal line or not can be observed quite visually by comparing the position of the upper end of the ball net and the positions of the visual laser beams.
Description
Technical field
The present invention relates to height measuring device, specifically a kind of net class ball project net height measurement mechanism.
Background technology
The competition rule that the net globoids such as tennis, shuttlecock, vollyball and beach volleyball are educated project requires as follows: the first, the height of disparity items (or sex or competition group) net is different; The second, net two ends and central height will be in the same horizontal line, and its error range must meet the requirements.
In practice, because same net is used by disparity items (or sex or competition group), therefore need to adjust frequently net height, when adjusting net height, need accurately to measure, the instrument of at present conventional measurement net height is traditional straight-bar type scale, and this scale is merely able to the height of a position of disposable measurement net, and whether cannot intuitively observe net two ends and central height at same level line, thereby while causing adjusting net height, work efficiency is high and measure out of true.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of simple in structure, measure accurate net class ball project net height measurement mechanism.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: net class ball project net height measurement mechanism, it comprises base and is fixed on the vertical scale on base, scale is provided with the vernier being slidably matched with it, vernier is provided with two generating lasers, two generating lasers are on sustained height, and the transmitting terminal of two generating lasers is towards the opposite, be provided with and make the locking mechanism fixed between the two between scale and vernier.
Described generating laser is common commercially available miniature laser transmitter, as laser pen etc.
For the purpose of succinct description, below net class ball project net height measurement mechanism of the present invention referred to as this measurement mechanism.
While using this measurement mechanism to carry out net height measurement, first vernier is adjusted to net desired height, by locking mechanism, vernier is fixed, then open generating laser, two generating lasers can be launched to both sides the visible laser beam such as redness or blueness, and the visible laser beam that two generating lasers send is positioned at same level line, by the visible laser beam on same level line, can measure like this height of all positions of net simultaneously, by comparing the position relationship of net upper end and visible laser beam, whether in the same horizontal line just can observe very intuitively net two ends and central height, thereby handled easily personnel adjust net two ends and central height.
From technique scheme, this proving installation is simple in structure, by this proving installation, whether in the same horizontal line not only can intuitively observe net two ends and central height, and it measures accurately, has promoted the work efficiency of adjusting net height.
As improvement of the present invention, the xsect of scale is rectangular, the xsect side of the being annular of vernier, and vernier is enclosed within on scale, and described locking mechanism comprises the tapped through hole having on vernier and is connected in the bolt on tapped through hole.Adopt this structure to vernier, to be fixed easily, unclamp bolt, vernier can move along scale easy on and off, and slider position tights a bolt after determining.
Preferably, described bolt is wing bolt.
As improvement of the present invention, the xsect of scale is rounded, vernier is the annular with opening, its two ends have respectively outwardly directed clamping plate, vernier is enclosed within on scale, described locking mechanism comprises through hole and the screw bolt and nut having on two clamping plate, and bolt is through through hole, nut and bolt-connection on two clamping plate.Adopt this structure to vernier, to be fixed easily, unclamp nut, between vernier and scale, produce gap, vernier can move along scale easy on and off, and after slider position is determined, fastening nut, can effectively fix vernier.
Preferably, described nut is wing nut.
