Description
Technical Field
The utility model relates to a duplexer field especially relates to a duplexer that shocks resistance.
Background
The duplexer is the main accessory of the different-frequency duplex radio station and the relay station, and has the function of isolating the transmitted signal from the received signal and ensuring that the receiving and the transmitting can work normally at the same time. It is composed of two groups of band-stop filters with different frequencies to prevent the transmission of local transmitting signals to the receiver.
and current duplexer is mostly the rectangle structure, when taking place the striking to the duplexer in the external world, will aggravate the striking to the duplexer, current duplexer does not set up the device that shocks resistance, when receiving external impact, be difficult for protecting the duplexer, current duplexer is generally fixed in a certain position, when the duplexer bumps, be difficult for slowing down the striking of duplexer, the life of duplexer has been reduced, therefore, need design a duplexer that shocks resistance and solve the not enough of prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the not enough of prior art, provide a duplexer that shocks resistance.
The utility model discloses a realize through following technical scheme:
The utility model provides a duplexer that shocks resistance, is including holding the frame, it installs the connecting block to hold frame left and right sides face symmetry, the screw has been seted up on the connecting block, it installs the protective layer to hold frame internal surface symmetry, hold both sides wall about the frame and seted up the guide slot, it all overlaps and is equipped with the slider to hold both sides wall about the frame, slider right side fixed mounting has second coil spring, second coil spring right-hand member fixed mounting has the locating piece, the locating piece with hold and install fastening screw between the frame, be provided with the duplexer between the slider, the duplexer respectively with between the slider symmetry install first coil spring, the duplexer surface evenly is provided with the joint.
As the utility model discloses an optimal technical scheme, slider and locating piece respectively with hold frame sliding fit.
As the utility model discloses a preferred technical scheme, the duplexer is circular structure.
As the preferred technical scheme of the utility model, the protective layer is made for rubber materials.
As the utility model discloses an optimized technical scheme, hold the frame inboard and seted up the guide slot corresponding with the slider.
Compared with the prior art, the beneficial effects of the utility model are that:
The utility model discloses a set the duplexer to circular structure, when the duplexer takes place to strike, will slow down the striking to the duplexer, setting through the protective layer, thereby can realize the protection to the duplexer, buffer the duplexer when the duplexer bumps, and simultaneously, send into when offeing at the duplexer, because the slider is to first coil spring's pulling, thereby can make the duplexer reset fast, for fixing the duplexer in fixed position, make the duplexer can move about, thereby more help the protection to the duplexer, through the setting of first coil spring and second coil spring, the setting of recombination protective layer, thereby can carry out multiple protection to the duplexer, slow down the impact to the duplexer, and reasonable in design, and convenient for operation, accord with the demand in duplexer field.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. duplexer, 2, joint, 3, first coil spring, 4, slider, 5, second coil spring, 6, locating piece, 7, fastening screw, 8, guide slot, 9, hold the frame, 10, connecting block, 11, protective layer, 12, screw.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution:
The utility model provides a duplexer that shocks resistance, is including holding frame 9, hold frame 9 left and right sides face symmetric mounting and have connecting block 10, screw 12 has been seted up on the connecting block 10, hold frame 9 internal surface symmetry and install protective layer 11, hold about frame 9 both sides wall and seted up guide slot 8, hold about frame 9 both sides wall all overlap and be equipped with slider 4, 4 right side fixed mounting of slider has second coil spring 5, 5 right-hand member fixed mounting of second coil spring have locating piece 6, locating piece 6 and hold and install fastening screw 7 between the frame 9, be provided with duplexer 1 between the slider 4, duplexer 1 respectively and slider 4 between the symmetry install first coil spring 3, duplexer 1 surface evenly is provided with connects 2.
The sliding block 4 and the positioning block 6 are respectively in sliding fit with the containing frame 9.
The duplexer 1 is of a circular structure.
The protective layer 11 is made of rubber material.
The inner side of the containing frame 9 is provided with a guide groove corresponding to the slide block 4.
The working principle is as follows: firstly, screws are screwed in the screw holes 12, the containing frame 9 is positioned at the position needing to be installed, when an impact occurs to the duplexer 1, the duplexer 1 will be caused to pull the first coil spring 3, when the sliding block 4 is pulled and the duplexer 1 impacts the protective layer 11, the protective layer 11 can protect the duplexer 1, the damage of the duplexer 1 caused by the too heavy collision of the duplexer 1 can be avoided, due to the pulling of the first coil spring 3 and the second coil spring 5, the slider 4 is facilitated to slide reciprocally, thereby realizing the pulling of the duplexer 1 and slowing down the impact on the duplexer 1, and the duplexer 1 of the device is arranged in a round shape, thereby reducing the edges and corners, therefore, when the duplexer 1 is impacted, the impact contact area is correspondingly reduced, so that the impact surface contact is converted into point contact, and the duplexer 1 has the function of resisting impact.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
