Description
Technical field
The utility model is related to production and processing equipment technical fields, more particularly to a kind of pulley track modular construction.
Background technology
PCBA board (printed circuit board) is widely used at present, and PCBA board is the important component part of electronic product, in group
With before preceding or manufacture in order to ensure the quality of product, it usually needs carry out various functions test and burn-in test, existing test
When equipment is tested, usually by trial product to be measured or the fixture of trial product to be measured need to be mounted with it is pushed into test station, push
Cheng Zhong, there are larger frictions between the trial product to be measured or the fixture and test equipment, on the one hand, trial product to be measured or fixture
It is not easy push-in and releases test equipment, on the other hand, trial product to be measured easy tos produce electrostatic with test equipment, is easy when electrostatic is excessive
Extremely unstable when causing to test, there are great security risks.
Utility model content
To solve the above problems, the utility model provides a kind of pulley track modular construction, convenient for push, installation side
Just.
To solve above-mentioned purpose, the following technical solution that the utility model uses.
A kind of pulley track modular construction, including two groups of pulley assemblies being symmetrical set, pulley assembly are equipped with support frame
Frame, two groups of support plates and several pulleys, braced frame are equipped with the groove body that is symmetrical set along the y direction of braced frame, and two
Group support plate is inserted into respectively in corresponding groove body, several pulleys turnably are installed between two groups of support plates.
As the further scheme of the utility model, support plate offers U-shaped card slot, and pulley is connected with bolt, bolt two
End is respectively clamped into the U-shaped card slot of corresponding support plate.
As the further scheme of the utility model, braced frame is connected with baffle.
As the further scheme of the utility model, braced frame both ends are equipped with the positioning deviate from for barrier support plate
Mechanism.
As the further scheme of the utility model, braced frame material is aluminium alloy.
The beneficial effects of the utility model are as follows：
The braced frame of the utility model is fixed with two groups of support plates without bolt, is directly inserted into two groups of support plates
Can be completed assembly in corresponding groove body, installation is more convenient, several pulleys turnably be installed in two groups of support plates it
Between, convenient for pushing trial product to be measured, while the friction coefficient between trial product and test equipment to be measured can be reduced, it can be significantly
The electrostatic generated by friction during push is reduced, the harm of electrostatic generation is thereby reduced, promotes the stability of test.

Fig. 2 is the dimensional structure diagram of the pulley assembly of the utility model；
Fig. 3 is the pulley assembly main structure diagram of the utility model；
Fig. 4 is the dimensional structure diagram of the support plate of the utility model.
Reference sign：1. pulley assembly, 2. braced frames, 21. groove bodies, 3. support plates, 31.U shapes card slot, 4. are slided
Wheel, 5. bolts, 6. baffles, 7. detent mechanisms.
Specific implementation mode
The utility model is further described below in conjunction with attached drawing.
Referring to figs. 1 to Fig. 4, a kind of pulley track modular construction, including two groups of pulley assemblies 1 being symmetrical set, pulley
Component 1 is equipped with 2, two groups of support plates 3 of braced frame and several pulleys 4, braced frame 2 are set along the y direction of braced frame 2
There are the groove body 21 being symmetrical set, two groups of support plates 3 to be inserted into respectively in corresponding groove body 21, several pulleys 4 are turnably
It is installed between two groups of support plates 3.Using above-mentioned technical proposal, the braced frame 2 of the utility model is not necessarily to two groups of support plates 3
It being fixed by bolts, directly two groups of support plates 3 is inserted into corresponding groove body 21, assembly can be completed, installation is more convenient, if
Dry pulley 4 turnably is installed between two groups of support plates 3, convenient for pushing trial product to be measured, while can be reduced to be measured
Friction coefficient between trial product and test equipment can substantially reduce the electrostatic generated by friction during push, into
And the harm of electrostatic generation is reduced, promote the stability of test.
Fig. 4 shows that support plate 3 offers U-shaped card slot 31, and pulley 4 is connected with bolt 5, and 5 both ends of bolt are respectively clamped into correspondence
In the U-shaped card slot 31 of support plate 3, timing is organized, bolt 5 is worn into pulley 4 and by the U for being fastened on support plate 3 at 5 both ends of bolt
In shape card slot 31, thus pulley 4 is rotationally installed between two groups of support plates 3, fixed without screw, and assembly is more convenient.
With reference to Fig. 2 and Fig. 3, braced frame 2 is connected with baffle 6, and baffle 6 can prevent trial product to be measured from being pushed away in push-in
Former preset path is detached from during going out, 6 unitary design of braced frame 2 and baffle exempts to install, use is more convenient.
Fig. 1 and Fig. 2 shows 2 both ends of braced frame are equipped with the detent mechanism 7 deviate from for barrier support plate 3, localization machine
Structure 7 plays positioning action to support plate 3, prevents the abjection out of braced frame 2 of support plate 3 so that pulley 4 can when in use may be used
It is secured entirely on braced frame 2, unnecessary displacement will not occur.
2 material of braced frame of the present embodiment is aluminium alloy, aluminium alloy extrusions lighter in weight so that this pulley track component
Weight reduction reduces overall load.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
