Abstract
The utility model discloses a guard bar connecting device which comprises a spring, a bolt, an elastic seat and a supporting frame. The elastic seat can be fixedly connected with a handrail. The supporting frame is fixedly connected with a pillar. Installation holes for installation of the bolt are formed in the elastic seat and the supporting frame. The bolt sequentially penetrates through the spring, the installation hole in the elastic seat and the installation in the supporting frame and presses the spring, the elastic seat and the supporting frame tightly. When outer force borne by the elastic seat is larger than the elastic force of the spring, the elastic seat is disengaged from the supporting frame and can slide on the bolt. When the outer force borne by the elastic seat disappears or is smaller than the elastic force of the spring, the spring can bounce the elastic seat back and press the supporting frame tightly. The guard bar connecting device is an improvement of a current guard rail connecting manner and makes connection installation and maintenance of the pillar of a guard rail and the handrail of the guard rail more convenient. When the handrail and the pillar of the guard rail are collided, the handrail and the pillar can be elastically disengaged to prolong an action period of colliding force and reduce damage. The disengaged handrail and the pillar can easily recover to the normal connection state or be fixed to achieve the normal connection state.
Description
Technical field
The utility model relates to a kind of guardrail field, is specifically related to a kind of guardrail connector.
Background technology
Development along with urban construction, highway, the extension of road is widened and highway, the foundation of the security protection system of road, highway, therefore the guardrail of road has also obtained using widely, common employed guardrail is made of column and railing, this guardrail when mounted, sometimes adopting guardrail railing string to be loaded in the hole of fence upright directly connects, sometimes by welding or riveted way the guardrail railing is fixed on the fence upright, this class mode had both existed fabrication cycle long, shortcomings such as complex process, also be difficult to operate at the scene, often implement welding or riveted joint in specific place earlier, the scene that transports to then installs and fixes; And above-mentioned connected mode makes railing and column directly pure rigidly connected, when column or railing are subjected to external force collision, the column of whole row's guardrail and railing all can link impaired, also need cutting welding or riveted joint during maintain and replace, bring inconvenience and difficulty to maintenance operation.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, a kind of linkage is provided, described linkage can conveniently connect railing and the column of guardrail, railing is separated rapidly when being clashed into column, and the railing after separating is easy to recover or is returned to when using or separate preceding connection status with column.
The utility model solves the problems of the technologies described above the technical scheme that adopts, a kind of parts of guardrail linkage comprise spring, bolt, bullet seat and support, described bullet seat can be fastenedly connected with railing, described support can be fastenedly connected with column, and described bullet seat and support are provided with the installing hole for erection bolt; Behind installing hole on screw bolt passes spring, the bullet seat and the installing hole on the support above-mentioned parts are pressed together; The suffered external force of bullet seat is during greater than spring force, and the bullet seat separates with support and can slide also at bolt, and the suffered external force of bullet seat disappears or during less than spring force, spring rebounds the bullet seat and the bullet seat is pressed on the support.
Preferably, bullet seat and support are provided with card post and the bayonet socket of mutual location.
Preferably, the bullet seat is provided with the screw that is connected for railing.
Preferably, support is provided with the screw that is connected for column.
Preferably, support is provided with for the fin that supports and locate railing.
Compared with prior art, guardrail linkage of the present utility model has improved the connected mode of existing guardrail, make that the railing installation, maintenance of the column of guardrail and guardrail is more simple and convenient, and when the railing of guardrail and column when being subjected to clashing into, reduce infringement the action time that railing and column can also resilient separation prolong impact, and railing and column can be automatically or repaired quickly and reset afterwards.

Fig. 1 is guardrail linkage schematic diagram;
Fig. 2 is guardrail linkage assembly schematic diagram;
Fig. 3 is guardrail linkage scheme of installation.
The specific embodiment
The utility model describes in further detail below in conjunction with accompanying drawing 1,2,3 embodiment.
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, a kind of linkage is provided, it can conveniently connect railing 6 and the column 5 of guardrail, separate rapidly when it can also make railing 6 be subjected to clashing into column 5, and the railing 6 after separating and column 5 are easy to reply or repair when using or the normal connection status before impaired.At present, the railing 6 of guardrail and column 5 all are to be made by hollow tube, and the tubing of hollow also is convenient to install miscellaneous part except in light weight.Described guardrail linkage has just utilized the characteristics of tubing hollow.
The utility model solves the problems of the technologies described above the technical scheme that adopts, described guardrail linkage comprises parts spring 1, bolt 2, bullet seat 3 and support 4, bullet seat 3 can be fastenedly connected with railing 6, support 4 can be fastenedly connected with column 5, described bullet seat 3 is provided with the installing hole 31 for erection bolt 2, support 4 is provided with the installing hole 41 for erection bolt 2, and installing hole 31 and installing hole 41 are coaxial through hole when installment state; Bolt 2 after passing on installing hole 31 on spring 1, the bullet seat 3 and the support 4 installing hole 41 successively is pressed together above-mentioned parts; Installing hole 31 is that through hole is used for bolt 2 and passes through, and installing hole 41 can be through hole, also can in establish screw thread and be directly used in bolt 2 and install, also can be in an end tightening nuts of bolt 2, that provide among the figure is the screw on embodiment of nut of bolt 2 ends of thread; After bolt 2 was assembled into the guardrail linkage with spring 1, bullet seat 3 and support 4, bullet seat 3 was fitting face with the face of the combination of support 4 assemblings, and bullet seat 3 is under the effect of spring 1 elastic force and tightly compressed by the support 4 of bolt 2 pulling force, and fitting face closely cooperates.When bullet seat 3 suffered external force during greater than spring 1 elastic force, bullet seat 3 separates with support 4 and can slide at bolt 2, and bullet seat 3 suffered external force disappear or during less than spring 1 elastic force, spring 1 rebounds bullet seat 3 and bullet seat 3 is pressed on the support 4.Bullet seat 3 and support 4 are provided with card post 42 and the bayonet socket 32 of mutual location, and the cooperation that is used for bullet seat 3 and support 4 is installed, and except the form of card post 42 and buckle 32, also can be the modes that bayonet lock and hole clipping cooperate, and implementation can be for multiple.Bullet seat 3 is provided with the screw 33 that is connected for railing 6, and bolt passes railing 6 backs and tightens with screw 33, and bullet seat 3 is fixed on the railing 6.Support 4 is provided with the screw 43 that is connected for column 5, and column 5 general both sides all can connect 6, one bolts of railing can pass screw 43 on the support and the through hole on the column, and support 4 is fixed on the column 5.Also be provided with on the support 4 for the fin 44 that supports and locate railing 6.
