[0002] Barrier gate, also known as car stop, is a management equipment specially set on the road for limiting the access of vehicles, commonly seen at the entrance of community, parking lot and other places, the existing barrier gate usually includes machine body and gate lever, the controller, drive machine and transmission shaft are installed in the machine body, one end of the gate lever is fixedly connected with the transmission shaft, when working, the controller controls the drive machine to operate to drive the transmission shaft to rotate, which promotes the gate lever to rotate with the transmission shaft.
[0003] However, in the use process of barrier gate, some driver misoperation and other situations will inevitably occur, which will cause the vehicle to impact the gate lever, the gate lever will be deformed in the process of being impacted and will transmit part of the impact force to the transmission shaft through the connection between the gate lever and the transmission shaft, which may cause the transmission shaft to be damaged, and the transmission shaft needs to be replaced, increasing the maintenance cost.
[0004] Therefore, a new scheme needs to be proposed to solve this problem. UTILITY MODEL CONTENTS
[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a barrier gate.
[0006] The above technical purpose of the utility model is realized by the following technical scheme: a barrier gate, comprising a machine body and a gate lever, a transmission shaft is rotatably connected in the machine body, the gate lever comprises a long part and a short part, a circular hole for the transmission shaft to pass through is formed in the short part, and a breakage groove is formed at the connection between the long part and the short part.
[0007] The utility model is further provided as follows: a weight reduction cavity is formed in the long part, and a reinforcing block is arranged in the weight reduction cavity and parallel to the front and rear two side walls of the long part.
[0008] The utility model is further provided as follows: a transmission key is arranged on the outer peripheral wall of the transmission shaft, a key groove for the transmission key to be embedded is formed in the inner peripheral wall of the circular hole, and the center of the key groove is located on the extension line of the center line of the long part.
[0009] The utility model is further provided as follows: the length of the reinforcing block is less than the length of the long part, and one end of the reinforcing block is flush with one end of the long part away from the short part.
[0010] The utility model is further provided as follows: the number of breakage grooves is two, and the two breakage grooves are respectively formed on the front and rear two side walls of the long part.

[0012] The present invention is further configured such that the gate arm is made of PVC material.
[0013] In summary, this utility model has the following beneficial effects:
[0014] When a vehicle impacts the gate arm, the opening of the impact groove makes the wall thickness of the gate arm thinner at that point. The impact force of the vehicle on the gate arm is more likely to form stress concentration at the impact groove, making it easier for the long part to separate from the short part after being impacted. This reduces the impact force transmitted to the short part, reduces the impact on the drive shaft when the vehicle hits the gate arm, and thus reduces the possibility of damage to the drive shaft due to the vehicle impact.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] A type of barrier gate, such as Figure 1 As shown, the device includes a body 1 and a brake arm. A drive shaft 2 is rotatably connected to the body 1. The brake arm includes a long part 4 and a short part 5. A circular hole 6 is provided on the short part 5 for the drive shaft 2 to pass through. A break-off groove 3 is provided at the connection between the long part 4 and the short part 5. When the brake arm is in a horizontal position, the length of the short part 5 does not exceed one-sixth of the length of the long part 4. When a vehicle hits the brake arm, the break-off groove 3 makes the brake arm thinner at that point. The impact force of the vehicle on the brake arm is easily concentrated at the break-off groove 3, making it easier for the long part 4 to separate from the short part 5 after being hit by the impact force. This reduces the impact force transmitted to the short part 5 and reduces the impact on the drive shaft 2 when the vehicle hits the brake arm, thereby reducing the possibility of damage to the drive shaft 2 due to the vehicle impact.
[0021] like Figure 2 and Figure 3As shown, the long part 4 is provided with a weight-reducing cavity, which can effectively reduce the weight of the long part 4, so that the torque required by the rotating shaft when driving the short part 5 to rotate is smaller, and the long part 4 is easier to be lifted. The weight-reducing cavity is provided with a reinforcing block 7 arranged in parallel with the front and rear side walls of the long part 4, which can better improve the rigidity of the long part 4 in the vertical direction. The outer peripheral wall of the transmission shaft 2 is provided with a transmission key 8, and the inner peripheral wall of the circular hole 6 is provided with a key groove 9 for embedding the transmission key 8. The cooperation between the transmission key 8 and the inner wall of the key groove 9 makes it difficult for the transmission shaft 2 and the inner wall of the circular hole 6 to rotate relative to each other, so that the torque of the transmission shaft 2 can be better transmitted to the short part 5, facilitating the control of the transmission shaft 2 on the gate lever. The center of the key groove 9 is located on the extension line of the center line of the long part 4, and the transmission key 8 is fixed in the key groove 9 by screws. This arrangement makes the transmission shaft 2 have the transmission key 8 as support on the extension line of the center line of the long part 4, so that the thickness is thicker, the rigidity is higher, and the anti-deformation ability is stronger. When the long part 4 is hit by a vehicle, the instantaneous impact force is transmitted to the transmission shaft 2 along the gate lever, so that the transmission shaft 2 is less likely to deform, and the possibility of damage to the transmission shaft 2 caused by the vehicle hitting the gate lever can be reduced. The length of the reinforcing block 7 is less than the length of the long part 4, and one end of the reinforcing block 7 is flush with one end of the long part 4 away from the short part 5. This arrangement makes the reinforcing block 7 not connected with the short part 5, so that the long part 4 is more likely to break at the breakage groove 3 when impacted, thereby reducing the impact on the short part 5 and the transmission shaft 2.
[0022] As shown in the drawings, Figure 2 The number of breakage grooves 3 is two, and the two breakage grooves 3 are arranged on the front and rear side walls of the long part 4, respectively. This arrangement makes the upper and lower side walls of the gate lever better connect the long part 4 and the short part 5, so that the transmission shaft 2 is not easy to break at the breakage groove 3 when providing torque to the short part 5 to make the long part 4 and the short part 5 rotate together, ensuring that the gate lever can be used normally. The long part 4 is provided with a plurality of through holes 10 penetrating the reinforcing block 7, and the plurality of through holes 10 are arranged at equal intervals along the length direction of the long part 4. When strong convective weather such as strong wind occurs, the through holes 10 can effectively reduce the windward area of the long part 4, thereby reducing the possibility of the gate lever being blown off at the breakage groove 3 in strong wind weather. The gate lever is made of PVC material, and the long part 4, the short part 5 and the breakage groove 3 are formed by one mold. The PVC material has the advantages of light weight and good weather resistance, so that the gate lever made of this material is relatively light and can adapt to the working environment exposed to the outside for a long time, thereby improving the service life of the gate lever.
