Editorial Note 2016100452 There are three pages of description only An embedded ground lock Technical field This utility model relates to an embedded ground lock. Background technology In existing technology, most bicycle ground locks achieve fixation through the screw and the ground. As time goes on, the lock will become loose so that the anti-burglary ability reduces and the bicycle may be easily stolen. Based on the above problem, a ground lock structure which can effectively prevent levering is required. Invention content The technical problem to be solved by this utility model is to provide an embedded ground lock. During using the device, the locking bar fits with the hollow rod to complete locking. The locking bar is embedded in the groove. In normal conditions, the device can lock well and avoid loss. The pouring rod connects with the ground, which enhances fixation firmness of this device and avoids levering To solve the above problem, this utility model adopts the following technical proposal: An embedded ground lock includes the disk. Annular groove is set on the top of disk. Locking bar of semi-arc shape is set in the groove. Through-hole is set on the outer ring of disk. The through-hole passes through the groove. The locking bar owns the first through hole which fits with the through-hole. A spindle fits between the through-hole and the first through-hole. A nut fits at both ends of spindle. Pouring rod is set at the axis at the bottom of disk. The pouring rod is a hollow rod. Optimally, two force application grooves which fit with the groove are symmetrically set at the top of disk. Optimally, both ends of the first through-hole own large aperture part. Seal ring is embedded in the large aperture part. The spindle passes through the seal ring. The seal ring and the spindle form sealing. Optimally, an improved embedded ground lock is characterized by that, the spindle is solid. Optimally, an opening is set at the bottom of pouring rod. At least one assembling hole is set on the rod body of pouring rod. Transverse pouring rod is inserted in the assembling hole. Optimally, the first groove is set at the axis at the top of disk. Grade plate is embedded in the first groove. Beneficial effects of this utility model are as follows: during using the device, the locking bar fits with the hollow rod to complete locking. The locking bar is embedded in the groove. In normal conditions, the device can lock well and avoid loss. The pouring rod connects with the ground, which enhances fixation firmness of this device and avoids levering. The structure of this device is simple, and its cost is low. Besides, it is convenient to use. Hence, 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 section view of this utility model; Fig.2 is vertical view 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 Figs.1-2, an embedded ground lock includes the disk 1. Annular groove 101 is set on the top of disk 1. Locking bar of semi arc shape 2 is set in the groove 101. Through-hole 102 is set on the outer ring of disk 1. The through-hole 102 passes through the groove 101. The locking bar 2 owns the first through-hole 201 which fits with the through-hole 102. A spindle 3 fits between the through-hole 102 and the first through-hole 201. A nut 301 fits at both ends of spindle 3. Pouring rod 4 is set at the axis at the bottom of disk 1. The pouring rod 4 is a hollow rod. As an optimal implementation example, two force application grooves 111 which fit with the groove 101 are symmetrically set at the top of disk 1. As an optimal implementation example, both ends of the first through-hole 201 own large aperture part (not shown). Seal ring 211 is embedded in the large aperture part. The spindle 3 passes through the seal ring 211. The seal ring 211 and the spindle 3 form sealing. As an optimal implementation example, the spindle 3 is solid. As an optimal implementation example, an opening is set at the bottom of pouring rod 4. At least one assembling hole 411 is set on the rod body of pouring rod 4. Transverse pouring rod 412 is inserted in the assembling hole 411. As an optimal implementation example, the first groove 123 is set at the axis at the top of disk 1. Grade plate 124 is embedded in the first groove 123. Beneficial effects of this utility model are as follows: during using the device, the locking bar fits with the hollow rod to complete locking. The locking bar is embedded in the groove. In normal conditions, the device can lock well and avoid loss. The pouring rod connects with the ground, which enhances fixation firmness of this device and avoids levering. The structure of this device is simple, and its cost is low. Besides, it is convenient to use. Hence, it is suitable for promotion.
The above content shows and describes the fundamentals, main features and advantages of this utility model. The technicians of this industry should know this utility model is not limited to the implementation example mentioned above. The above implementation example and descriptions just depict the principle of this utility model. There will be various changes and improvements for this utility model without deviation from the spirit and range of this utility model. These changes and improvements will be included in the range of the protected utility model. The scope of protection required by this utility model is defined by the claim attached and its equivalent.
