Abstract
The utility model discloses a tension spring part for a tread hammer, which comprises a tension spring, an upper tension spring block and a lower tension spring block. The upper tension spring block and the lower tension spring block are respectively arranged at the two ends of the tension spring. The tension spring is composed of a spring and draw hooks at the two ends of the spring. The corresponding sides of the upper and lower tension spring blocks are provided with pins connected with the draw hooks of the tension spring. The top of the upper tension spring block is provided with a semicircular hole used for the pin of the tread hammer to pass through, wherein the pin cannot be freely rotated after passing through the hole. In this way, during the rotation of the tread hammer, the tread hammer exerts a pull force on the upper tension spring block, and then further exerts the pull force onto the tension spring. A bearing is arranged between the pin of the upper tension spring block and the semicircular hole. According to the technical scheme of the utility model, the tread hammer is driven to reset in position under the elastic force of the tension spring part. Since the tension spring is connected with the bearing, the movement of the tension spring part is not limited in a linear manner during the force transmission process. Therefore, the sensitivity of the tread hammer is greatly improved.
Description
Technical field
The utility model belongs to percussion instrument accessory field, particularly relates to a kind of for stepping on the extension spring parts of hammer.
Background technology
Existing stepping on beaten effort of drum, and less to the hitting dynamics of drum, striking frequency is lower, and drumstick position is not easy to reply.
Summary of the invention
In order to solve the problems of the technologies described above, it is a kind of for stepping on the extension spring parts of hammer that the utility model provides, and relies on spring to impel and step on the reply of hammer position, greatly improved the sensitivity of stepping on hammer.
For this reason, technical solutions of the utility model are as follows:
For stepping on extension spring parts for hammer, comprise extension spring and be arranged at respectively upper extension spring piece and the tension spring piece at extension spring two ends; Described extension spring is comprised of the drag hook of spring and both ends of the spring; Described upper and lower extension spring piece respective side is provided with the pin that connects extension spring drag hook, and upper extension spring piece top is formed with the semi-circular hole of passing and can not arbitrarily rotate for the bearing pin of hammering into shape; The rotational that guarantees hammer produces pulling force to upper extension spring piece, then extension spring is produced to pulling force; Between the pin of described upper extension spring piece and semi-circular hole, be divided into two sections, and two sections of dependence bearings connections, make extension spring parts not only be defined as rectilinear motion, improve its sensitivity.
The pin downside of described tension spring piece is a screw rod with two nuts.
Described upper extension spring piece top is provided with the polygonal screw rod with nut, for these extension spring parts are connected with associated components.
This steps on the extension spring parts of hammer, relies on spring to impel and steps on the reply of hammer position, and connection bearing in power transmittance process, makes extension spring parts not only be defined as rectilinear motion, has greatly improved the sensitivity of stepping on hammer.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model extension spring parts;
Fig. 2 is the left view of the utility model extension spring parts.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1: a kind of for stepping on the extension spring parts of hammer, comprise extension spring 1 and be arranged at respectively upper extension spring piece 2 and the tension spring piece 3 at extension spring two ends; Described extension spring 1 is comprised of the drag hook of spring and both ends of the spring; Described upper and lower extension spring piece 2,3 respective side are provided with the pin 4,5 that connects extension spring 1 drag hook, and upper extension spring piece 2 tops are formed with the semi-circular hole 6 of passing and can not arbitrarily rotate for the bearing pin of hammering into shape; The rotational that guarantees hammer produces pulling force to upper extension spring piece, then extension spring is produced to pulling force; Between the pin 4 of described upper extension spring piece 2 and semi-circular hole 6, be divided into two sections, and two sections of dependence bearings 9 connections, make extension spring parts not only be defined as rectilinear motion, improve its sensitivity.
Described upper extension spring piece 2 tops are provided with the polygonal screw rod 8 with nut, for these extension spring parts are connected with associated components.
This steps on the extension spring parts of hammer, relies on spring to impel and steps on the reply of hammer position, and connection bearing in power transmittance process, makes extension spring parts not only be defined as rectilinear motion, has greatly improved the sensitivity of stepping on hammer.
