Editorial Note 2016100454 There are 3 pages of Description A modified automobile wheel protection lock Technical field This utility model relates to a modified automobile wheel protection lock. Background technology When a vehicle parks on a ramp for a long time, it is necessary to put a protection lock below the tire to avoid sliding. However, in existing technology, the structure of protection lock is complex, and the weight is large. So, it is inconvenient to carry. For female drivers, it is strenuous to operate. Invention content The technical problem to be solved by this utility model is to provide a modified automobile wheel protection lock. The structure of this device is simple. Through adjusting the elevation angle of limit plate, the limit need of tires with different size can be met to avoid sliding. Besides, the structure volume of this device is small, so it is convenient to use. The protective pad protects the tire from abrading. To solve the above problem, this utility model adopts the following technical proposal: A modified automobile wheel protection lock includes the base plate. A slope is set at the top of base plate near the right side. A groove is set at the top of base plate. A through-hole is set at the front end dace of base plate. The through-hole passes through the groove. Limit plate is set in the groove. The limit plate has the first through-hole which fits with the through-hole. A bolt is between the through-hole and the first through-hole. A limit slot is set at the front end face of base plate. The limit slot passes through the base plate lengthways. Locking groove is set at the bottom of limit slot. A locking rod is in the locking groove. The locking rod leans against the lower surface of limit plate. The limit plate has an upper surface with sunken arc. Protective pad is set on the upper surface of limit plate. The protective pad and the limit plate are fixed by gluing. The protective pad is made of rubber. Optimally, the base plate is of circular arc transition at the right end; the thickness of base plate is 8mm-16mm. Optimally, the first groove is set at the bottom of base plate. Anti-skidding mat is set in the first groove. The anti-skidding mat is made of rubber. The thickness of anti-skidding mat is 2mm-3mm. The thickness of anti-skidding mat is greater than the depth of the first groove. Beneficial effects of this utility model are as follows: the structure of this device is simple. Through adjusting the elevation angle of limit plate, the limit need of tires with different size can be met to avoid sliding. Besides, the structure volume of this device is small, so it is convenient to use. The protective pad protects the tire from abrading. The cost of this device is low, so it is suitable for promotion.
Descriptions of attached figures To explain the implementation example or the technical proposal more clearly, the attached figure used in the implementation example or the technical proposal is simply introduced as follows. Obviously, the attached figure just describes some implementation examples of this utility model. For common technical personnel in this field, they can gain other attached figures under the precondition of no creative work. Fig.1 is structure diagram of this utility model. Detailed implementation way The optimized implementation example of this utility model is elaborated as follows in combination of the attached figure so that the advantages and features of this utility model can be easily understood by technical personnel in this field and the protection scope of this utility model can be defined more clearly and explicitly. According to Fig.1, a modified automobile wheel protection lock includes the base plate 1. A slope 101 is set at the top of base plate 1 near the right side. A groove (not shown) is set at the top of base plate 1. A through-hole 102 is set at the front end dace of base plate 1. The through-hole 102 is a stepped-type hole. The through-hole 102 passes through the groove. Limit plate 2 is set in the groove. The limit plate 2 has the first through-hole (not shown) which fits with the through-hole 102. A bolt 3 is between the through-hole 102 and the first through-hole. A limit slot 4 is set at the front end face of base plate 1. The limit slot 4 passes through the base plate 1 lengthways. Locking groove 401 is set at the bottom of limit slot 4. A locking rod 402 is in the locking groove 401. The locking rod 402 leans against the lower surface of limit plate 2. The limit plate 2 has an upper surface with sunken arc. Protective pad 211 is set on the upper surface of limit plate 2. The protective pad 211 and the limit plate 2 are fixed by gluing. The protective pad 211 is made of rubber. As an optimal implementation example, the base plate 1 is of circular arc transition at the right end; the thickness of base plate 1 is 8mm-16mm. As an optimal implementation example, the first groove (not shown) is set at the bottom of base plate 1. Anti-skidding mat 111 is set in the first groove. The anti-skidding mat 111 is made of rubber. The thickness of anti-skidding mat 111 is 2mm-3mm. The thickness of anti-skidding mat 111 is greater than the depth of the first groove. Beneficial effects of this utility model are as follows: the structure of this device is simple. Through adjusting the elevation angle of limit plate, the limit need of tires with different size can be met to avoid sliding. Besides, the structure volume of this device is small, so it is convenient to use. The protective pad protects the tire from abrading. The cost of this device is low, so it is suitable for promotion.
